Abstract: Apparatus for hairdressers to use in coloring multiple, localized and isolated strands of hair, called highlighting. The task is made easier and the product better by making dozens of parts in the hair, extracting a few locks or strands along the length of each part, storing these selected strands between sheets of plastic film, and only then applying the color-imparting chemicals. The structure of the cap, by design, makes this procedure easy and straightforward for the first time.

Abstract: In the initial part of a wet-process rotary kiln, means to decrease the amount of product dust entrained in the escaping combustion gases. Pipes running lengthwise of the kiln, in the region where the feed slurry is wet enough to flow, fill with slurry as they rotate through the slurry pool at the bottom of the kiln, and discharge their contents through exit ports so placed on each pipe as to emit streams of slurry when the pipe is carried by kiln rotation to a position near the top of the kiln. In conjunction with the forest of chains commonly used in such kilns, the transverse-flowing combustion gases are scrubbed of some of their entrained product dust content by its being entrapped in wet slurry and recycled.

Abstract: The combination of a converter in which liquid petroleum gas is changed in phase from liquid to gas preparatory to fueling an internal combustion engine by adding heat from a fluid, a dual three-way valve, an air-fluid heat exchanger in a human-occupied compartment (the cab), and a fluid circulation system independent of the internal combustion engine cooling system. The dual three-way valve's position either directs engine coolant tapped from the engine through the converter and air-fluid heat exchanger, partially cooling the cab, or directs fluid from the independent fluid circulation system through the converter and air-fluid heat exchanger, fully cooling the cab. As an alternate embodiment for installations when engine coolant can become temporarily too hot to exit the inverter below ambient cab temperature, an independent bypass may be incorporated.

Abstract: A defense system which provides turret-like platforms equipped with missiles at various points on an airplane or helicopter. The missiles are recoiless and may be either self-guided or aviator-guided. The number of missiles and type of launch (pylon or tube) provided are considered to be changeable according to the mission, but this invention only addresses the use of multiple rotatable platforms compatible with existing weaponry and technology.

Abstract: Apparatus and method for making an immersed fuel transfer pump free of possible sources of ignition for fuel-vapor mixtures when the pump is run dry. The bearings and face seals are cooled by hydraulic oil used to power the pump, preferably through connecting the case leakage port on a conventional multiple piston type hydraulic motor to the pump as a supply and ducting the leakage through the bearings and near the seals on its way to the reservoir. An auxiliary pump built into the centrifugal pump shaft increases flow over these critical parts via a closed loop. Leakage past the dynamic face seals is led overboard through a flame-quenching passage.

Abstract: A harness to be worn during situp exercises, the benefit being that it provides a non-moving portion to support the head. The cross strap behind the head which constitutes this non-moving portion is mounted on straps held about eye level by the hands during situps, wound partially around the upper torso, and attached in front of the body to a belt.

Abstract: A dust collector based on filtration of dirty air in which the periodic backflushing of filtration elements is done by admitting atmospheric air at the filtration element exit port. The air is sucked backwards through the filtration element by the dust collector exit blower. Switching between normal usage and backflush is done by inserting a diverter valve containing a valve chamber between the filtration element discharge part and the clean air chamber. The porting of this valve chamber may be to either the atmosphere or to the clean air chamber, which being determined by twisting a shaft slightly less than 90 degrees, said shaft having valve closure plates attached to it at slightly greater than 90.degree. to each other. Twisting force need not be applied during normal operation nor to close off the atmospheric air port. Further, dust shields are provided around each filtration element to prevent backflushed dust moving directly to an adjacent filtration element.

Abstract: A device which rotates an armature through a sequence of angular positions cyclically, using control of the current in a second stator winding while maximum current is applied to a first stator winding. The magnetic poles associated with the two windings are circumferentially offset from each other.

Abstract: A device for use in removal/replacement of single rivets or other fasteners in lines of same, by holding a drill bushing holder rigidly above the defective fastener. The unique features are a tongue and groove joint midway along the device, which can then be locked at any angle, and multiple narrow holddown slots which slide on the anchoring bolts in one direction only, expediting position adjustment.

Abstract: A device for securing eyeglasses to the ear of the wearer, using a ring of stretched elastomer on the bow or temple piece forward of the ear and adjustable in position. A loose loop of flexible line is tied to the ring, and extends in a larger loop around the ear at its base, with a sheath for padding where it touches the ear. The wearer adjusts the ring so as to create a slight force in the larger loop, which force prevents the bow from lifting off the top of the ear, which in turn prevents the eyeglasses from slipping forward down the slope of the nose.

Abstract: A prescription vial which counts cyclically, through a window in the cap, how many times it has been opened/closed that day. The construction is unique in that the principal parts can be formed with straight strokes of the forming press, thus they are suitable for mass production. Spring fingers on an index plate extend past the sealing disc to ride on the upper flank of the closure threads. The fingers touch the thread at a flat helical angle. When the cap is rotated in one direction the index plate and fingers move with it; in the other direction the cap turns but the fingers will not pass an abutment on the thread, so force the index plate to turn inside the cap.

Abstract: A motorized propulsion device for swimmers and scuba divers which is to be attached to the user's forearms. The battery, motor, propeller and propeller shroud are arranged in a compact, linear, hydrodynamic manner. The watertight housing may have one or more integrally shaped nesting protuberances to comfortably accommodate the user's forearm and thereby prevent slippage. The front end surface of the housing has a control panel within reach of the user's fingers.

Abstract: Portable apparatus for breaking the bead of a rubber tire, in which the wheel is placed over a center post. An A frame lying on its side and pivoted at its apex has a shorter lower leg which contacts the root of the tire sidewall and a longer upper leg which is forced downward by a power screw or the like pivoting the A frame and forcing a section of tire bead over the internal ridge on the rim. An adjustment screw meanwhile forces the tip of the lower leg toward the rim which is restrained by the center post.

Abstract: A support for the prone back during an upper enema, in which the legs are folded, with the feet resting on footrests and the buttocks adjacent to an effluent shield which stops the effluent and allows it to drop into a toilet, on which the lower part of the support rests. The support is collapsible for transport or storage, as is a stand which is beneath the center of gravity of body plus support. This stand makes contact with the support on both sides of the center of gravity. At discharge it and the toilet bowl span the center of gravity; during the enema the patient may, by manipulating a lever, raise the buttock part of the support by means of a linkage as desired in order to produce a more thorough irrigation of the colon. Provision is also made for increasing colonic reaction by color and by reflexology prods on the soles of the feet.

Abstract: A tilt switch using a conductive liquid such as mercury to bridge a gap inside the sealed switch. In operation, the pool of mercury is held in a local depression and does not flow but rather distorts in shape enough to reach a ring-shaped second terminal which is spaced from and surrounds the mercury pool.

Abstract: In a lift bag used by divers to lift objects from the ocean bottom to the surface, this invention keeps constant the amount of flotation gas and hence the lift force. A hose connects the gas bubble trapped inside the bag to a point, lower on the bag wall, selected by the diver to give the desired lift force. As the device ascends, lifting the cargo to the surface, any excess volume of gas created by expansion is discharged through the hose. The purpose is to prevent uncontrolled rapid rise of the device which can cause deflation and re-sinking when the lift bag reaches the surface.

Abstract: A medicine bottle and cap, the cap containing a window through which one of several index marks, preferably serial numbers, is visible. The index marks are on a member nesting inside the cap and equipped with spring fingers set at an angle on a skirt. During opening of the bottle, this marked member is prevented from rotating as the cap is unscrewed, thus indexing the index marks. During closing, frictional forces cause all parts to rotate together.

Abstract: Apparatus for determining how squarely a golf club face is presented to the ball near and at the point at which the club face makes contact with the ball. Collimated light from outside the clubhead arc on the target line-of-flight strikes a reflective patch fixed to the club face. The reflected beam is picked up by sensors, each of which if struck by light switches on an adjacent marker light. Thus the path followed by the reflected beam during one stroke is marked in lights for study or playback. As few as one or as many as thousands of sensors may be used, with suitable adjustment to the optics. If the marker lights turned on are right or left of target it indicates a non-square blow. Information about clubface loft angle during the stroke is obtained from the starting and stopping point of the line of marker lights. Opening or closing the clubface near the contact point results in the line of marker lights being other than vertical.
