Abstract: A winged aircraft attachable to the body of a pilot including multiple jet engines whereby it may be propelled into and sustained in flight, having angularly adjustable side fins, having pilot operable controls for simultaneously controlling directional issuance of jet streams issuing from the engines and angular adjustment of the fins, including a support for the head of the pilot, and including a support for his feet.

Abstract: A single winged aircraft adapted to be attached to the back of a pilot, including a jet fuel engine whereby it may be propelled into space and sustained in flight, and provided with manually operable controls for controlling operation of ailerons and the directional issuance of the jet stream exhausting from the engine, whereby the aircraft may be directionally controlled in flight by the pilot.

Abstract: A bicycle having a frame extended rearwardly and beyond the rear wheel of the bicycle provided in the extended portion with a pedal crank driven sprocket connected by an endless drive chain with a sprocket gear carried by the rear wheel, the extended portion being in one form of the invention an integral part of the frame, or being in a modified form of the invention an accessory unit separably attachable to the conventional frame of a bicycle, in which modified form the sprocket gear is connectible by the drive chain, at the election of the rider, with either the pedal crank driven sprocket in the accessory unit or with the normal pedal crank driven sprocket in the conventional frame.

Abstract: A system for fuel drip priming an internal gasoline combustion engine of a motor vehicle so as to enable it to subsequently start up quickly after it has become cold from being parked in cold weather for several hours or overnight, in which system the fuel pump is connected through a selectively operable control valve unit with drip nozzle units mounted in the intake manifold near the intake ports of the engine, whereby in addition to the benefits of quick starting of the engine there is also obtained the resultant benefit of fuel saving.

Abstract: Ketchup rapping apparatus having a pair of L-form racks hinged to one another, each adapted to hold a ketchup bottle in a stationary seated position, one of the racks being pivotable through 180 degrees from a back-to-back relationship with the other rack to carry its bottle to inverted vertical alignment with the other bottle, a resilient guide cup to be disposed between the mouth ends of the aligned bottles for avoiding glass-to-glass bottle contact and for guiding the bottle being inverted down into the aligned position with the other bottle, a latch for securing the pivoted rack in the inverted position to allow easy porting of the apparatus in the inverted condition, and shock absorbing pads on the bottom of the non-inverted rack enabling rapping of the latter in the inverted condition of the apparatus against a solid surface so as to jar free a clogged ketchup flow condition without damaging the apparatus or the bottles.

Abstract: A hand held pneumatic nut running tool including an air vane rotary motor, manipulative valving for initially starting air flow to the motor and then terminating such flow, and an air flow shut-off control valve responsive to acceleration of the motor after start-up and before said termination of air flow to continue air flow to the motor, the control valve being further responsive to a predetermined level of deceleration of the motor to discontinue air flow to the motor.

Abstract: An air powered hand tool having combined therein nut running and crimping mechanism in which a common cam member is motor rotated to effect run down of a work nut about a stud and is piston driven to effect crimping of the nut in locking relation to the stud; in which an indicator visually indicates to the operator completion of the crimping action; and in which a stop prevents frictional locking of the cam member in the crimping action; and in which the stud is enabled to rise a considerable distance above the nut as the latter is run down.
