Abstract: A low pressure low volume plastic metering valve comprised of a cylinder having an external tapered port and a piston having a tapered through port for communicating with the port in said cylinder. Both the tapered port in the cylinder and the through port in the piston are offset from the axis of the cylinder and communicate with each other along an arcuate tapered passageway that varies from a maximum where the ports abut to a minimum. The piston is held by a lip on the cylinder walls which prevents axial movement of the piston but allows rotation of the piston to vary the fluid flow. Sealing is improved by constructing the cylinder of a yieldable plastic and the piston of a different plastic that is brittle and non-yielding.

Abstract: A separate reservoir of fuel having sufficient capacity to operate a vehicle for approximately ten minutes is inserted in the line between the fuel pump and the carburetor. A normally opened remote controlled valve is inserted between the reservoir and the fuel pump and which is independently operable by the vehicle owner. A vent is located in the uppermost portion of the reservoir and consists of a float type check valve that is closed by the rising level of fluid urged into the reservoir from the fuel pump. Leaving the valve open allows the vehicle to operate in the normal fashion. The operator closes the normally opened remotely located valve when leaving the vehicle or giving the vehicle to a parking attendant who has limited authority to only park and service the vehicle. Unauthorized use of the vehicle converts the pressurized fuel system into a gravity fuel system with the limited fuel flowing from the reservoir into the engine carburetor until the fuel is exhausted, thereby stalling the engine.

Abstract: A skateboard capable of being adjusted for different weights and different desired ride characteristics without changing the distance between the fore and aft wheels. The truck assembly is mounted on an angled leaf spring and the leaf spring is slideably engaged against a pad having shoulder guides. The pad mounts against the skateboard and the leaf spring is attached to the pad. In one embodiment, the pad contains slots and is movable in a fore and aft direction to change the spring constant of the leaf spring holding the truck. The leaf spring is fixedly positioned to the skateboard and the pad is free to move in a fore and aft direction as a result of the slots thereby allowing the rider to change the effect of the spring and hence the angle to obtain different ride characteristics.

Abstract: This invention describes apparatus and method for recycling undelivered cement left as residue in cement trucks. Undelivered cement at the end of the working day is deposited on a shaker screen under action of high pressure water jets which trap large aggregate and force the large aggregate onto a first belt for collection. Sand, cement and water fall through the first screen onto a second screen which traps sand under action of high pressure jets that force the sand onto a second belt for delivery to a collection area. The remaining cement, water and slurry is collected in a trough and pumped to a settling tank having an auger that periodically mixes the water and cement to prevent hardening. A skimmer located at the uppermost portion of the settling tank collects clear water used to clean the aggregate and cement previously mentioned. The cement, water and slurry collected in the settling tank is used in combination with fresh sand and cement to provide a fresh charge to waiting cement trucks.

Abstract: A voltage controlled attenuator having extremely wide dynamic range and having low distortion is achieved by limiting the current density in each unit area of the transistors to minimize the current noise and by utilizing high current sources to minimize the noise voltage. A pair of compound gain cells having low current densities are each directly fed by a linearized current source. The gain cells are controlled by a single gain control voltage and feed a pair of linearized buffer amplifiers for minimizing loading on the gain cells. The output of the buffer amplifiers feed a differential output amplifier for generating an output signal that eliminates the effect of the control voltage in the output signal and any DC shift caused by changes in control voltage and nulls remaining distortion products.

Abstract: This invention describes a system for displaying instruments in an overhead console in an automobile. A transverse instrument panel is located against the roofline of an automobile and located transverse of the automobile above the forward windshield. A centrally located cutout in the transverse panel allows a fore and aft beam to be attached to the roof member in the area of the rear view mirror at the forward part and near the dome light in the rearward portion. Tapered brackets attached to the fore and aft brace member hold instrument panels on each side and on the bottom most portion to thereby provide instrument panel space on both the driver's side and the passenger's side. The fore and aft instrument panels mate with the transverse panels giving the appearance of a single overhead instrument console.

Abstract: A method and apparatus for locating a grounded fault in an electrical circuit. An automatic resettable circuit breaker having two terminals is connected across a source of power and the circuit under test. The grounded fault condition causes the resettable circuit breaker to continually recycle in the presence of the grounded fault. An induction current measuring ammeter is movably positioned over the circuit under test to measure the varying current caused by the resettable circuit breaker. The actual location of the ground is determined by the immediate absence of a measured varying current.

Abstract: This invention describes a system and method for precisely locating a combined sleeve bolt in an opening located in a plurality of materials adapted to be connected together. The adjustable nut is constructed in two parts and rotatably attached to each other. The first part contains an internal thread for accepting one end of the sleeve bolt and a bearing surface for bearing only on one end of the projecting outer sleeve. The second portion of the nut has a greater diameter for bearing against the bottommost portion of the materials adapted to be connected together. The two portions of the nut being independently adjustable allow the sleeve bolt to be positioned within the hole regardless of any variations in the length of the sleeve. Once the desired position is achieved, the two portions are locked together, preferably by a set screw, and the tapered bolt is pulled into the hole while the adjustable nut holds the sleeve in the desired and pre-adjusted position.

Abstract: Pulses of ionized gas mixtures are generated periodically, to be entrained and accelerated inside a vessel in a predetermined direction by magnetic waves traveling transverse to the plasma motion. Phase coherence between the pulse train and the magnetic waves is maintained. The forces exerted by the magnetic waves cause the ion mixture of each pulse packet to be sorted into several separate packets in some of which the original concentration of a specific ion has been greatly increased or decreased. The waves then drive each packet into a separate branch of the vessel for recovery. The distance between these branches depends on the timing of the mixed pulse relative to the crest of the magnetic waves, on ion mass-to-charge differences, and on the intensity of the magnetic field. The separation efficiency may be enhanced by reducing the intensity of the magnetic field, by raising its frequency, and by shortening the mixed plasma packets while increasing their density.

Abstract: This invention describes a system and method for detecting unwanted pop and click sound signals caused by mechanical defects on a recording medium. A pair of wholly or partially correlated signals is generated from the recorded sound information by a conventional stereo pickup device. The output signals of the stereo pickup device are combined so that desired sound signals generated by horizontal movement on the record medium are subtracted and undesired signals generated by vertical movement on the record medium are added. The resulting undesired signal representing clicks and pops is detected as the noise signal. A gating signal starting before the leading edge of the detected undesired sound signal terminating innocuously on the sound signal, and having a width that is greater than the width of the detected undesired sound signal, is used in the system to eliminate the undesired signals.

Abstract: This invention describes apparatus and method for constructing an outer garment capable of being converted to a tote bag. The coat comprises a full belt forming an upper half and a lower half. The lower half has a pair of deep pockets having zippered openings on the uppermost portion only. The uppeer half also contains a pair of deep pockets having zippered openings on both the uppermost portion and the lowermost portion. Snap hooks located on the back of the collar and the back portion of the coat in the area of the belt are adapted to snap together thereby defining an equal upper and lower half. The coat is folded about the belt portion and hooks located on the outermost portion of the deep pockets are connected together thereby exposing the upper deep pockets on one side of the belt and the lower deep pockets on the other side of the belt. The belt is adjustable allowing the user to wear the tote bag over a shoulder or to hold the belt as a conventional bag.

Abstract: A fastener, primarily of the precision type for aircraft use in holding together multiple metal stack-ups, makes use of a sleeve, a headed shaft and a nut. The shaft and sleeve as a subassembly is inserted in a hole in a stack-up of sheets, the nut is applied to the shaft and the shaft is drawn forceably into the passageway to expand the sleeve laterally into anchored engagement with the wall of the hole. The fastener is of special construction in that it is an installation formed fastener and sleeve assembly for fatigue critical aircraft structure where the combination of sheet, plate, forgings and other fastener assembly materials may vary in modulus of elasticity, hardness and other physical properties. The fastener assembly consists of a sleeve, a bolt, rivet or stud, and suitable means of retention such as a self locking nut or collar. The sleeve is partially formed and machined to final dimension while in place on the exact bolt which is ultimately used when completing the fastener assembly in place.

Abstract: Charged particles are entrained on a straight or curved path by a traveling magnetic field moving along that path with its magnetic flux vector transverse thereto. The general direction of entrainment is the same for particles of either polarity. The initial relative velocity between the traveling field and the particle drives the latter into motions along a quasi-cycloidal trajectory in the direction of field travel at an average particle speed nearly equal to the field velocity. Streams of charged particles may be accelerated into streams separated from any material objects such as vessel walls, magnetic structures, electrodes, etc. This confinement is achieved predominantly by the balanced interaction of the forces exerted on the particles by the traveling magnetic field and their inertial forces. Auxiliary confining fields may be applied for redirecting to the main stream any particles scattered by secondary effects.

Abstract: An electrical feed-through assembly adapted to be directly connected to a bulkhead assembly for conducting high voltage electrical energy between a low pressure and high pressure area. A hollow casing is removably connected by conventional means of packing glands to a bulkhead assembly. Conductors located within the casing are completely covered by dielectric materials that are bonded directly to each conductor. The conductors and the dielectric materials have different internal and external diameters to form increased bonding areas for withstanding high pressure differentials and high voltage differentials. A deformable dielectric bonding material bonds the conductors to the casing in the area of high pressure. A non-deformable dielectric bonding material adjacent to the deformable bonding material bonds the conductors to the remaining inside area of the casing.

Abstract: An improved flexible merchandise display rack capable of displaying a plurality of similar sized swatches of materials such as carpet samples. A plurality of individual assemblies are each pivotably mounted on a vertical shaft. Each assembly consists of a pair of spaced-apart disc members separated by posts connected to opposite sides of opposing discs along the periphery thereof. The space between opposing discs is a function of the width of the individual samples that are inserted about one or two or even three of the posts with the end portion of the samples towards the central shaft. A plurality of the assemblies may be stacked one above the other on a single shaft thereby allowing a greater number of samples to be displayed in a given area than has heretofore been possible to achieve. In addition, the individual samples are all supported within each assembly thereby obviating the need for the customer to hold or otherwise support any of the samples.

All detected information at a given location is recorded and controlled by a transaction terminal located on the premises. A remotely located central processing unit automatically and periodically communicates with each of a plurality of remotely located transaction terminals for causing all recorded information in each transaction terminal to be transmitted and recorded at a centrally located central processing unit.

Abstract: A first aid package for emergency use in the field for treating and transporting seriously burned patients. The first aid package comprises a soft resilient water absorbent foam material placed on a flexible waterproof outer covering having a pair of interlocking portions. A sterile sheet is placed over the resilient foam material and the sheet and the foam are saturated with an aqueous solution. The burn patient is placed on the sterile sheet and completely covered by the sterile sheet thereby enclosing the patient in a sterile atmosphere. An aqueous solution is then poured over the sheet so as to completely saturate the sheet and the uppermost portion of the patient. The cooperating interlocking portions of the flexible waterproof covering are placed completely around the sheet and the patient and locked into position thereby maintaining the patient in a sterile moist atmosphere.

Abstract: A device to facilitate the pleating of a fabric material comprising a substantially flat sheet of plastic having alternating scorings on each side of the plastic device. On one side the scorings have a substantially V-shaped cross-section and on the opposite side the scorings have an arcuate cross-section. The scoring lines are parallel to each other and are equally spaced from each other to thereby facilitate folding the plastic device accordion style.

Abstract: An improved flushing valve for inter-connecting a water closet with a waste dispensing bowl for preventing overflow in the event of a line stoppage. The valve is opened in the ordinary manner and held open by the action of fluid flowing through the valve onto a floatable member having a positive buoyancy that maintains the valve in an open condition in the presence of fluid flow. In the absence of a fluid flow, the valve is allowed to close. In the presence of a line stoppage, overflow fluid will tend to back up causing the floatable member having a positive buoyancy to release the valve which is allowed to close thereby preventing discharge of any further fluid from the water closet. All attempts to operate the water valve will fail as long as the floatable member is held in a floatable condition by the overflow fluid.
