Abstract: The present invention relates to an aiming device for adjusting the optical axis of an automobile head lamp, characterized in that it comprises a hollow bearing attached to a movable member which is a lamp unit or a reflection mirror to be moved for adjusting the optical axis, a gear case housing a worm gear and a spur gear engaged with each other, the gear case being attached to a fixed member which is an autobody or a housing for supporting said movable member, an aiming screw whose head is fitted into said hollow bearing and whose screw portion is screwed into a female threaded hole formed in the shaft center of said spur gear, and a device for inhibiting said aiming screw from rotating circumferentially.

Abstract: Apparatus for monitoring the cooling system of a liquid-cooled automotive engine. The apparatus provides a warning of a malfunction within the system and diagnostic information of what the malfunction is. The compact apparatus is easily mounted in the inlet radiator hose and includes elements for measuring the coolant level, flow rate, pressure and temperature.

Abstract: There is disclosed a method of recovering a material active in the formation of new bone and cartilage from demineralized bone extract and the composition of said material on a pliable physiologically acceptable support.

Abstract: The invention describes an energy extractor for extracting energy from waves in the sea. A ring spine is disclosed and on the spine, spaced circumferentially thereof are flexible membranes which flex back and forth under the influence of the waves. The back and forth flexing deflects air back and forth and the air movement is used to drive air turbines and electrical generators. Arranging for the spine to be in a ring and spacing the membranes around the ring ensures efficient energy extraction regardless of wave direction.

Abstract: An anti-snoring device includes at least two clasps, each clamping around an upper molar tooth on opposite sides of the mouth; a bridge made of an acrylic-like material connecting the clasps; a button which applies pressure to the soft palate of the person; and an easily bendable wire interconnecting the button and the bridge such that the button applies pressure to the soft palate to prevent vibration thereof.

Abstract: A surgical retractor wherein a plurality of segments are strung together on a strand which may be tensioned; the segments are separated from each other by spacers also strung on the strand; the mating surfaces of the segments are concave and the intervening spacers are convex; tensioning of the strand causes the segments and spacers to frictionally engage each other and rigidize the attitude of the segments with respect to each other.

Abstract: A cantilever rack construction wherein a generally C-shaped connector plate embraces a flange of a column; threaded members pass through arms on the front of the connector plate and engage the column at or near to the root fillet; (which is the point of intersection of a flange on the column and the web of the column.

Abstract: An inflatable body suit is disclosed having the shape of a union suit. The suit has a first and a second layer extending over the entire area thereof defining an air pocket between them that terminates at a seam opening large enough to allow a wearer to put on or take off the suit. A compressed air reservoir is operatively connected to the air pocket, the reservoir having at least two compartments, each compartment having a compressed air capacity sufficient to inflate the air pocket. A detachable helmet is also secured to the suit and has valves for allowing the wearer of the suit to inhale and exhale air with respect to the outside of the suit. The suit is designed to keep the wearer afloat in water.

Abstract: A shrimp sheller having a probe for insertion into the body of a decapitated shrimp between the shell and the flesh, to be moved toward the tail; a sharp offset portion perpendicular to the probe slices through the shell from end to end as the probe is advanced through the tail, enabling the shell to be easily stripped off the body.

Abstract: A snap-action thermal switch having a housing with an open hollow portion at one end with a central enlargement of the housing in the hollow portion; a central cavity in the other end of the housing extending into the central enlargement; a pair of opposed slots communicating between the hollow portions; through the enlargement into the cavity with stationary contact in the hollow portion extending through the slot into the cavity; the widest points of the internal rectangular cavity being equal to or greater than the width of the enlargement.

Abstract: A duplex trailer hitch which provides a hook and a pivotable closure to receive a lunette, and a ball on the end of the end of the hook to receive a coupler.

Abstract: A method of and apparatus for transporting and conditioning a web through a conditioning chamber wherein the web pursues a sinusoidal path, being sustained by air issuing from an apparatus having rectangular openings to move air over a convex indentation and tangentially over the surface of a convex nozzle, and a plurality of air jets issuing from orifices in a direction generally perpendicular to the convex nozzle.

Abstract: Frame location system for microfilm retrieval system. Frame address of desired frame is stored in first reversible counter having maximum count greater than the maximum possible number of frames in a roll of microfilm. Frame address of frame currently being viewed is stored in second reversible counter of same count capacity. A burst of pulses equal to capacity of both counters causes both to count up. First counter to overflow gates burst pulses into third reversible counter. Second counter to overflow terminates count in third counter. As microfilm moves, optical sensors sense frame identifying "blips" on microfilm thereby reducing count in third counter and slowing film to halt when desired frame is in position at viewing station.

Abstract: Analog display utilizing liquid crystal material and for being multiplexed wherein the segments (one group of electrodes) are arranged in groups opposite sectors (the counter electrodes) and wherein the segments in each group are disposed in a sequence opposite to the sequence in which the segments of the next adjacent group are disposed and, further, wherein a segment in each group corresponds to a segment in each other group and wherein all corresponding segments are electrically interconnected in a series connection. In timed sequence with the input signals applied to the sectors, input signals are applied to the segments in a first predetermined sequence with regard to a direction of display movement to be provided by the display, and alternately, the input signals are applied to the segments in an opposite sequence with regard to the direction of display movement whereby the display movement is in one continuous direction.
