Abstract: An eyedrop bottle attachment has a pair of flexible arms which, in use, extend upwardly therefrom. The arms are squeezed together somewhat, and pads on the ends of the arms are pressed gently against the closed eyelids so that when released, the arms flex back to force the eyelids apart. Thereafter, the pads hold the eye open and provide a steady support for the bottle to insure accurate placement of the drops.

Abstract: Apparatus and method for forming cylindrical tubular lateral extensions on cylindrical or oval body tube by swaging them from around an oval opening, which is narrower along the sides to compensate for the body curvature, the apparatus including a circular male swaging die with a profile that tapers at progressively decreasing angles to the stroke direction, i.e. a series of progressively steeper conical surfaces or a sphere. The die may be a complete ball which is rolled into a formed body tube; positioned over an opening therein and pushed therethrough by a ram driven through the opposite, aligned opening. The body tube may then be inverted and another ball rolled therein to be pushed through the opposite opening.

Abstract: A shielded letter opener comprising a finger having a relatively pointed distal end to be inserted under the flap of a sealed envelope and carrying a cutting blade extending upwardly therefrom and facing forwardly. An elongated hood with depending sides extends above and embraces the blade and the finger to protect the user.

Abstract: A gate valve comprising a fabricated tubular cylindrical body with circular plate end closures. Back up rings are secured to the inner surface of the body to extend axially beyond the ends thereof and welds are placed between the closure plates and the annular ends of the body around the cylindrical surfaces of the back up rings to firmly unitize the tubular body and the end plates. One end closure plate has a slot therein to receive the valve gate closely therethrough for installation and removal thereof as required. The slot is covered by a generally rectangular bonnet plate.

Abstract: A protective glove, particularly for use in skateboarding, wherein the risk of falling is great. At the palm portion between a leather cover and an inner liner, is secured a thick resilient pad disposed to overlie the heel of the palm to absorb shock from impact, when one attempts to break his fall with extended hands. At the base of the glove is secured heavy elastic wrist band to protect against sprains as a result of such impact, and to co-act with the pad and glove leather in transferring and distributing impact forces from the palm pad and glove to the arm of the wearer.

Abstract: A vehicle wheel speed retarding system comprising a positive displacement fluid pump in a liquid system adapted to be driven by positive engagement with means on the wheel drive. The output of the pump is delivered to a valve and governor means also driven by the vehicle wheel drive operates the valve to reduce its flow capacity with increase in speed, thus retarding the positive displacement pump and, hence, the vehicle wheel. Manually regulated means, such as controlled air pressure acting against a diaphragm, resists movement of the valve to control the speed capacity of the device. Failure of air pressure will result in minimum speed capacity.

Abstract: A heat transfer system for cooling water, comprising a relatively large air duct which is open to ambient air at the upstream end, where there is situated an annular, coaxial nozzle to jet hot water through a venturi tube toward the downstream end of the air duct. The high velocity stream of water draws air into the low pressure zone to intermix with the finely divided water droplets moving downstream. The water is cooled by transfer of heat of vaporization as well as by transfer from the air itself, whereby water drawn from the downstream end of the air duct is cool enough for recycling.

Abstract: A vented top for a bacteria culture medium tube having a body with through openings to hold one or more tubes simultaneously. A cap closes off all openings or opens them together. Vent means enable automatic venting of gases generated by the bacteria.

Abstract: A game-board with a series of spaces representing letters of the alphabet forming a continuous path along which game pieces are moved. Letter tiles, determined by the lettered spaces to which game pieces are moved, are purchased. Words from such letters are placed on a player's own word board, which has a limited number of horizontal and vertical spaces. There are four groups of letters, each valued in accordance with the difficulty of forming words therewith, and play money is awarded to players for the total of words formed.

Abstract: A pipeline break detection system wherein a rate timer valve is opened in response to a predetermined pressure drop to direct pressure fluid to activate the time cycle of an on-delay valve and, itself commence a time delay closing cycle. If its closing countdown continues to completion, it depressurizes the on-delay output valve and cancels its countdown. However, if the pipeline experiences a further like pressure drop, before the rate timer valve closes, it will be recharged and held open to keep the output valve timer actuated. If the pipeline pressure fails to level off to allow the rate timer valve to close, and the output relay is thus enabled to complete its timed cycle, the output relay opens to deliver a fluid signal.

Abstract: An emergency hydraulic ram valve actuator having redundant power sources and controls. At least two pressure fluid sources, such as hydraulic accumulators, are connected through separate controls to the cylinder head. Check valves in the cylinder head and base prevent outward flow to insure containment of the fluid even when dismantled for service. Both sets of controls are contained in manifolds connected between the pressure sources and pressure and exhaust lines to and from the cylinder. Flow from each accumulator is normally prevented by a pilot check valve, but selectively operated valves initiate flow which, in turn, biases the pilot check valves to full flow. As full flow commences a portion thereof is diverted to open the exhaust pilot check valves which allow cylinder evacuation. In the event one power and/or control system is disabled, the other will function independently. The pressure and exhaust lines are contained within protective shields throughout their lengths.

Abstract: A valve wherein an expansible tube is stretched around a hollow core, which has a central barrier between inlet and outlet slots around the core. An annular groove is formed around the outer sealing surface of the barrier and extensions of some of the downstream slots open into the groove to vent the groove and produce a pressure drop across the expansible tube to enhance sealing and to provide an initial flow path when the tube is forced away from the sealing surface.

Abstract: A water saving device for a toilet tank comprising an open top container with partitions forming an inverted U, siphon duct opening adjacent the bottom of the container and extending over an end wall to discharge below the container bottom. A top wall seals across the tops of the partitions, with a check valve therein to prevent the entrapment of air. A vent tube opens through the top wall from outside the toilet tank and a shut off valve is selectively operated to open or seal off the vent tube.

Abstract: A variable impact jarring tool comprising a handled shaft with a massive impact sleeve slideable thereon. A self-tapping screw on the end of the shaft is driven to grip the workpiece and a first collar adjacent the handle serves as an anvil against which the sleeve impacts. A second collar may be fixed on the shaft in either of two positions, one adjacent the end for a full impact stroke and the other midway thereof for a limited stroke, but providing more clearance at the end for placement of the screw in close places.

Abstract: A pressure control valve wherein the monitored pressure acts against a diaphragm in opposition to a fixed biasing force which urges a poppet valve away from the seat. A disc with a small orifice therein covers a sensing port whereby flow of the monitored pressure into and out of the diaphragm chamber is retarded to minimize chatter of the diaphragm. A spring holding the orifice disc in place may be overcome by the monitored pressure to allow inward flow around the disc in the event that the orifice is occluded, whereby the valve will not enable undesirable pressure build up in the system in response to a false low pressure signal.

Abstract: A device for adjusting the front wheel alignment of an automotive vehicle including a McPherson-type strut, the upper end of which is carried on the vehicle frame for limited pivotal movement and the lower end of which carries the wheel spindle assembly. The lower end of the strut is fixed on a steering arm which is pivoted on the lower ball joint. A cylindrical mounting member on which the lower ball joint stud is eccentrically secured may be rotated on the steering arm to vary the position of the strut axis relative to the fixed lower ball joint axis, pivoting the strut about its upper end mounting to adjust the camber and caster of the wheel. After the adjustment is made, the bolts attaching the steering arm to the strut are tightened to clamp the cylindrical mounting member in place.

Abstract: An educational device for teaching one to lace shoes comprising a pair of panel members hingedly secured to a base to simulate the side flaps of a lace-up shoe. Areas along the edges of the flaps around the holes are two colors alternately arranged and each end of the shoestring is colored to match one of the hole designation colors, whereby the shoe is laced by threading the shoestring through openings of like colors. Crossed lines of the same colors are placed on the base member to direct crossing of the lace ends and a spot directs placement of a finger to loop the first half of a bow.
