Abstract: A toy projectile comprising an upper stage having a segmented, tubular rocket-simulating body in which segments or vanes are hinged and formed to provide a rocket vehicle-like configuration in the closed condition and, upon opening, provide radially disposed air foil members which operate in the manner of an autogyro or helicopter to provide gyro rotation of the vehicle for slow descent after it has reached its apogee. The lower stage comprises a tube which is slidably and frictionally receivable within a lower adaptor portion on the upper stage so as to removably mount the lower stage on the upper stage. A solid grain propellant engine, including a thrust charge, delay and separation charge, is mounted in the tube of the lower stage. The lower stage serves to retain the segments or vanes in a closed condition before separation of the upper and lower stages by the separation charge within the lower stage.

Abstract: An adjustable height gauge for use in hair cutting. The gauge is worn on the thumb, much like a ring, and includes a platform of adjustable height that supports the index finger of the same hand. The index finger and middle finger are used to grasp a section of hair and then the gauge is placed under the index finger in contact with the scalp and hair extending beyond the fingers is cut off. This device allows a person to cut his or her own hair by feel to any desired series of lengths for shaping and grooming.

Abstract: Lighting apparatus comprising a long span lightweight luminaire beam with a cross section that is substantially in the shape of an equilateral triangle and is formed in multiple sections secured together. One apex of the triangle is pointed downwardly. The side panels of the beam are used as mounting and reflecting surfaces for fluorescent lights or the like, while the ballast and wiring are mounted inside the beam to protect them from weather. The mounting hole for the ballast also serves as the access hole for assembly of the span, and the ballast may be inverted in its mounting for servicing. The beam is supported in an elevated, substantially horizontally extending position by one or more support posts. This apparatus is particularly advantageous for use in illuminating large outdoor areas such as tennis courts.

Abstract: A power take-off mechanism which converts rotational motion to a variety of available rotating, reciprocating and/or oscillating motions. The device comprises a rocking frame within which is mounted a rotating shaft on which is mounted an unbalanced weight. One end of the shaft is connected through a constant velocity type joint to a power source and the opposite end of the shaft rotates within a restraining ring or area on the frame. The rotating unbalanced weight transmits force through the shaft to the rocking frame which is free to pivot or move rotationally about one axis and at the same time to reciprocate axially along the same axis. Power may be taken off from various points on the frame as either reciprocating motion, reciprocating motion with a cyclicly reversing twist, circular motion inscribed on a plane of rotation, or eliptical motion inscribed on a plane of rotation.

Abstract: This invention provides a pressure transmitting and sealing apparatus between a high or low pressure fluid line and a gauge monitoring the pressure of the fluid in the line. This apparatus transmits pressure fluctuations between the measured fluid and a dissimilar fluid in the standing line connected to the measuring gauge. The invention is particularly applicable in instances where the ambient temperature is below the freezing point of the measured fluid and a non-freezing fluid is required in the standing line and gauge. The apparatus comprises an in-line piston and cylinder unit which transmits variations in the pressure in the measured line to the fluid in the standing line to the gauge, while maintaining separation of the two fluids and at the same time allowing the non-freezing fluid in the standing line to lubricate the piston and cylinder. In the event of a break in the standing line, the piston will prevent leakage from the measured fluid line.

Abstract: A fish hook with a reverse bend near the end of the shank which forms an almost closed loop. A second hook or auxiliary lure or streamer may be attached by slipping the eye thereof over the point and barb of the first hook and snapping the eye of the second hook into the loop near the end of the shank of the first hook.

Abstract: An improved veneer lathe which cuts off a sheet of veneer from a log supported rotatably by applying a torque directly to the outer periphery of the log. An external force for cutting the log is fed from the vicinity of a knife included in the lathe. The log core is not subjected to a load attributable to a cutting resistance so that even logs of a poor quality are usable for turning veneer sheets therefrom, enhancing the yield of plywood production.

Abstract: A carburetor comprising a body defining a throat, a throttle slide member slidably mounted on the body and disposed in the throat, and a tapered metering rod or needle mounted on the slide member and extending downwardly into a fuel supply tube leading into a fuel reservoir or bowl secured to the body. The slide member has front and rear, substantially flat panels disposed in substantially parallel relation, with the front panel being shorter than the rear panel for the purpose of providing air at the outlet of the fuel supply tube even when the slide is in a closed position and for directing air toward the outlet when the slide is in an open position. The body is provided with a substantially axial groove intersecting the fuel outlet at the throat for the purpose of directing high speed air flow toward the metering rod and over the fuel outlet when the slide is opened.
