Abstract: A disposable low cost electrode structure for measuring platelet aggregation in whole blood or PRP which utilizes conductive ink or foil for the electrodes with the electrode pattern printed, heat-stamped or silk-screened onto a suitable plastic non-reactive base. The base material can be any material which does not react with blood and is stiff enough, for example a polycarbonate, while the conductive element can be made with a silver conductive ink. The electrodes can be on one or both sides of the base or substrate material. Platelet aggregates start and build up on the leading edge of a narrow body inserted into the flow path of the blood. The conductive pattern must have its active element on or very near the leading edge of the electrode base material, and in contact with the blood, and the non-active areas of the conductive pattern must be insulated electrically from the blood or plasma being tested so as to allow sensing of the change in resistance caused by the platelet build-up on the active area.

Abstract: A wood or coal burning heater or stove employing a catalytic combustor in its combustion chamber having a primary air supply which feeds air to the fuel, and a secondary air supply which feeds air directly to the catalytic combustor by means of an air diffuser which sprays air evenly over the undersurface of the catalytic combustor. Combustion gases from the burning fuel in the combustion chamber pass through the catalytic combustor to a heat exchanger and then to an exhaust flue. The primary and secondary air supplies are simultaneously controlled so that maximum primary air and reduced secondary air are supplied when maximum heat is demanded, and reduced primary air and maximum secondary air are supplied when minimum heat is demanded. The ratio of primary to secondary air is precisely controlled to maximize overall heating efficiency consonant with high BTU output.

Abstract: A locking wheeled locking carrier including a pair of identical molded half carriage parts each of which carries a pair of canted wheels to support the carrier within a track, and a pendulum part pivoted between the carriage halves and extending downward through the bottom slot in the ceiling track for suspending a desired article. The two carriage halves are slidably interfitted with one another for lateral movement toward and away from one another within the ceiling track, and the pendulum pivot extends slidably through both carriage halves. In the vertical pendulum position a camming action exerted by the pendulum on the two carriage halves forces the carriage halves laterally apart from one another so that their outside surfaces engage the ceiling track slot walls and frictionally lock the carriage in position.

Abstract: A clutch system providing a simplified clutch adjustment which also gives an indication of how much clutch facing remains so that it is known when a clutch face needs replacement. The system mounts the motor armature and flywheel in a bearing structure which is axially shiftable toward the clutch face by utilization of a rotatable element threadedly engaged with the main frame of the motor and which presents against one end of the bearing structure so that it may shift the bearing structure and the entire armature and flywheel by rotation of the threaded element. This threaded element is coupled to the fan cowl of the motor which is in turn held in fixed position by a latching member. With the latching member released, the fan cowl is rotatable to adjust the flywheel, with the fan cowl then being again latched into position to prevent further movement of the flywheel in an axial direction.

Abstract: The method of making cast barrier structures consisting of the steps of, securing a plurality of form plates in a longitudinally spaced array over a supporting surface with the major plane of each form plate oriented substantially vertically and transversely to the length of the array, positioning side panels longitudinally alongside the form plates on opposite sides thereof and extending the length of the array, the side panels having upper and lower longitudinally extending edges with the lower edges seated on the underlying supporting surface and having irregularities on the inside surface which faces the form plates, fixedly securing the side panels to the form plates to form with the form plates and underlying surface an open-topped hollow assembly, and pouring a solidifiable plastic material downward through the open top of the hollow assembly to completely fill the interior thereof and integrally bond together the form plates and the side panels and the plastic material when the latter solidifies.

Abstract: A steam sterilization system for a filling machine having dispensing nozzles connected to a source of product supply, the sterilizing system including a novel autoclave apparatus and a novel condensate purge system. The autoclave structure causes sterilizing steam to flow downward through the inside of the dispensing nozzle to its open ended bottom where it reverses and flows upward between the inside face of a reversing tube and the outside face of the dispensing nozzle to a series of holes through the sidewall of the reversing tube where it emerges and goes down between the outside face of the reversing tube and the inside face of the autoclave shell thereafter passing down into a steam and condensate line. Condensate formed within the dispensing tube drips out the bottom of the dispensing tube and through an aperture at the bottom of the reversing tube, the condensate effectively sealing the bottom of the reversing tube to steam.

Abstract: A fluorescent lamp system including a pair of fluorescent lamp socket bars, a pair of ballast transformers, and a wiring harness. Each lamp socket bar consists of a sandwich of a molded plastic plate which holds the lamp socket contacts and the wiring connector pins, and a printed circuit wiring plate which makes electrical contact with the socket contacts and connector pins through mechanical pressure contact, and which wiring plate contains the circuit wiring excepting for the interconnections with the ballast transformers, such interconnections being effected either by means of a wiring harness having plug connectors which pluggingly connect to pins on the lamp socket bar and to the ballast transformers or by quick-wire connections from the ballast transformers themselves. If a cable harness is used, the ballasts are also pluggably engageable with the fluorescent lamp socket bars.

Abstract: A barrier structure comprising a number of spaced apart inline vertical I-beam sections embedded in a road and having secured to the posts a number of form plates having a pair of downwardly and outwardly diverging legs and a pair of upwardly diverging extending arms, which plates have ears turned out of them used to secure the plates to the I-beams. Reinforcing rods are extended through alined apertures in a number of consecutively spaced plates, and end connected side panels are secured to tabs on the side edges of the plates and interfittingly engaged with the bottoms of the plates legs and the tops of the plates arms so that the side panels are retained in a predetermined position with respect to the upstanding plates. Concrete is poured down through the open top of the structure to completely fill the inside to the top of the side panels which act as a form for the concrete being poured, and which side panels are bonded to the concrete and remain as a permanent part of the barrier structure.

Abstract: An abrasive scrubbing pad device combined with a wringer mop in which the scrubbing pad when not in use is automatically placed in a physical position which does not interfere with the normal mop function of the mop by an automatic pivoting action brought into operation by actuation of the crank handle of the wringer mop. When the crank handle of the wringer mop is moved to the position where the mop head is functional for mopping purposes, the scrubber pad is pivoted out of the way, and when the actuating handle is operated to retract the mop head between the wringer rollers during a squeeze-out operation, the scrubber pad is pivoted into its operating position. The scrubber pad may be incorporated into the mop when originally asssembled or may be added to the mop at a later time. The scrubber pad structure is formed so that the scrubber pad itself may be replaced in the support structure when the pad has been rendered no longer useful by virtue of wear.

Abstract: A flexible traffic standard which includes an anchor support assembly consisting of a hollow cylindrical tube and a driving point, and a resilient standard assembly comprising a tempered spring steel strap, the bottom end of which is disposed within a rigid tube, and a resilient tubular cover which encloses the strap and tube. The resilient standard assembly is disposed within the hollow cylindrical tube of the anchor support assembly and is secured by means of a pair of compression bolts. A rain boot prevents water from running down into the tube and a rain cap prevents the entry of water through the top of the flexible standard. The tempered spring steel strap which forms the resilient core of the device is reversely folded at its midpoint, to form a pair of upwardly extending resilient arms which are laterally outwardly offset by means of a twist in the spring steel at the midpoint reverse point.

Abstract: The invention provides internal self testing within an integrated circuit chip at all points along the logic chain. Internal stimulus generators and supervisory control circuits for the generators formed integrally within a VLSI chip are utilized together with integrally formed multiple fault detectors to provide self testing of the logic chain, mechanical interconnection failures, and power and clock pulse checking. The invention is utilizable in conjunction with either single or duplicate logic, which latter may be either duplicate complementary logic or duplicate functional logic. The multiple fault detectors provide a multiplicity of error signals which are multiplexed within the chip to produce encoded output error signals each of which designates the fault which has been detected within the chip. The invention eliminates the need for sophisticated ancillary test systems for diagnostic and go/no-go or confidence testing for hardware at the chip, board and system level.

Abstract: A T-carrier digital test system which actively monitors each T-carrier wire pair on a time division multiplexing basis while either live communications or test signals are on the line, and determines from the monitored data whether an incipient or hard failure of the line exists. It achieves this result by utilization of interacting devices called Scanners and Scanner Controllers. Each Scanner is housed in a repeater case and is connected to and monitors the output of each regenerative repeater in that case. The Scanner also connects to a fault line which runs in parallel to the T-Carrier wire pair and acts as the communications media and power path between several Scanners and the telecommunications facilities at each end of the cable pair.

Abstract: The filling systems according to the invention utilize pneumatic pressure maintained within closely held tolerance limits to impose a constant dispensing force upon the material being dispensed. The invention in one embodiment utilizes a buffer tank system in which the product to be dispensed is transferred from a supply tank (11) to the buffer tank (12) where the desired pressure is induced through a pneumatic head which is introduced above the product level. The product level in the buffer tank (12) is allowed to fluctuate within a relatively narrow band of depth so as to negate the effect of changes in gravity head pressure. The closed and pressurized system is refilled by forcing the incoming product into the tank (12) under a higher pressure than that in the buffer tank (12). The air within the tank (12) that is displaced as a result of introducing the new product is automatically vented to atmosphere through a precision regulation system (45).

Abstract: A container for shipping and storing large hollow cylindrical rolls of either solid material or wound sheet material. A skid or pallet is combined with a pair of special corrugated paperboard end pads, one for each end of the roll, a pair of spaced apart anti-roll retainers extending longitudinally of and secured to the top of the pallet and between which the roll is placed, a pair of top braces extending between and interfitted with the end pads, a pair of banding straps which transversely encircle and secure together the retained roll and the anti-roll retainers, and a pair of banding straps which longitudinally encircle and secure together the pallet and end pads and top braces. The end pads and anti-roll retainers secure the retained roll from endwise shifting and sidewise rolling motion, and are constructed so that a standard sized end section is utilizable with rolls of widely varying diameters.

Abstract: A locking plier type of device which is provided with very large gripping jaw surfaces movable into face to face apposition, with each being provided with arcuately curved rows of arcuate teeth or serrations which interfit with one another when the jaws are brought together. The arcuate teeth or serrations are angled so that oppositely directed pulls on the tool and the sheet metal clamped between the jaws of the tool tends to cause the serrations to penetrate slightly into the surface of the sheet metal to thereby increase the grip of the tool on the sheet metal. Platen type jaws on the order of an inch and three eighths to an inch and a half square produce quite satisfactory results and permit the exertion of very strong pulling forces on sheet metal panels of substantial size.

Abstract: A resilient traffic standard or bumper includes a dome of resilient material having a central tubular section oriented orthogonally to the support surface and within which tubular section is disposable any one of a number of different types of standards. The outside of the central tubular section is surrounded by a compression spring which helps to restore the resilient dome to its undeformed shape after it has been impacted by a vehicle. The entire structure is anchored to the support surface through the bottom of the central tubular sections. A plurality of resilient domes are stackable and securable together for anchoring to a wall to function as a resilient bumper.
