Abstract: An anti-crime device, known as the Anti-crime Spike-needle, is an inconspicuous device that is attachable in any quantity to fur-coats and other garments and articles, and is harmless to the wearers and users of such garments and articles, but it can sting and injure anyone who uses force or unnecessarily heavy pressure to hold, pull, push, detain, or strike the wearer or the user thereof. Its main components consist of a spike-needle and a hair-like resilient steel wire, the former's needle-sharp point is prevented from touching anyone who is friendly by the latter which encircles or stands next to the former. When a pressure greater than normal or friendly is applied on the garment or other article equipped with the device, such as by a criminal, the resilient hair-like wire or wires yield and expose the sharp point of the spike-needle and discourage and even stop any further overt act against the wearer or user thereof.

Abstract: This invention is intended to prevent the front seat riders of automotive vehicles from being thrown against the windshield when their speeding vehicle suddenly stops in an accident. It includes a collision contact bar, two longitudinal bars, a plurality of electric motors, shafts, chains, gear wheels, and a safety net. The collision contact bar which is securely positioned on the front of the vehicle's front bumper, if struck, causes the longitudinal bars to be pushed rearward, the movement of which closes the circuit to the electric motors, which turns the gear wheels and the shafts, and opens forwardly the windshield, which in turn pulls down a safety net between the front seat riders and its erstwhile position.

Abstract: This invention relates to an automotive vehicle's windshield expressly designed and purposely made to move forward or open automatically and to get out of the way of the vehicle's passengers who may be thrown against it by virtue of Newton's First Law Of Motion and the inertial property of matter when their speeding vehicle suddenly stops, and not designed or made to move or open manually, robotically, nor with any mechanical device for the purpose of ventilation or external communication.

Abstract: A safety device for a vehicle that uses inertia to prevent the upper body of an occupant from colliding with the windshield. A pair of bars are slidingly held to the underside of the vehicle's roof. The bars each have a row of gear teeth in engagement with a semi-circular gear. A net is secured to the semi-circular gears so that as inertia causes the sliding bars to move forward the gears turn and introduce the net between the occupants and the windshield. A ratchet wheel assembly prevents the safety device from moving backwards unless the pawls are manually released.

Abstract: The subject of this invention is a piston engine without cranks and crankshaft. Its pistons are operated by neither steam nor gaseous combustion. It depends on electrical energy, but in a manner quite different from those of the conventional electric cars and motors. Its principal parts include electromagnets having iron cores, electromagnets with magnetic-fluid cores, permanent magnets, pistons that could move reciprocatingly in said magnetic-fluid cores, hydraulically operated turbine receiving its pressure from said pistons, electromagnetically operated polarity wheel that performs functions resembling those of commutators and special computers in the selection, reversal, and timing of currents to insure the coordinated movements of the various parts of the engine.It may be operated as a direct current engine with energy derived from portable storage batteries or generators that are independent of fossil fuels. It does not pollute the atmosphere.
