Abstract: In a contactless ignition control system having a dwell time control circuit for an internal combustion engine, there is provided a speed responsive bias voltage circuit, a bias voltge switching circuit and a wave shaping circuit. The speed responsive bias voltage changes the switching level of the wave shaping circuit, thereby elongating the dwell time of the current flowing through an ignition coil.In the dwell time control, when the ignition timing comes, the bias voltage switching circuit prevents application of the speed responsive bias voltage so that the ignition timing is made irrespective of the speed responsive bias voltage.

Abstract: For a four cylinder engine, a first and second ignition coil, each having a primary and secondary winding is provided. A first and second electronic switch is connected in series wit the primary winding of each ignition coil and the so-formed series circuits are connected in parallel. A power switch is connected in series with the parallel combination. The power switch is switched to the conductive state a predetermined time interval prior to the ignition time and to the nonconductive state at each ignition time. The series switches are switched to the conductive state alternately during each cycle, but the switching occurs only when the power switch is in the nonconductive state. The on-offswitching of the series switch is controlled by a flip-flop which is clocked at the ignition time and which is initially synchronized to the ignition cycle by a signal derived from a sensor sensing a mark on a rotating shaft in the engine.

Abstract: A four stroke cycle internal combustion engine is presented having a sustained power stroke which results from a delayed mixing of a stratified charge. Use of delayed mixing of an overall stoichiometric air-fuel mixture results in formation of a low amount of the oxides of nitrogen. Delayed mixing of the stratified charge is achieved by placement of a Helmholtz resonator cavity in the head or closed end of each combustion chamber. The Helmholtz resonator cavity communicates with the main combustion chamber via a narrow slot made around the periphery of the top end of the chamber. On the intake stroke of each engine cylinder, the main chamber is filled with a slightly fuel rich gaseous charge while the companion Helmholtz resonator cavity is filled with air. During the compression stroke some of the rich air-fuel mixture is forced into the resonator cavity via the communicating slot. At or near TDC, the air-fuel mixture in the main chamber is ignited.

The control valve is actuated from an electronic system to render one or more cylinders inactive for certain engine power output.

Abstract: A heater system for warming the body of a diver while underwater, to be used in combination with and powered by an air supply tank is disclosed. In essence, the heater system functions by taking in controlled amounts of water from the ambient, heating this water and delivering it to the diver's suit.High-pressure air from the air supply is admitted into the heater system through a pressure regulator which reduces the air pressure and utilizes the energy thus provided to operate as a pneumatic motor and water-circulating pump. The reduced-pressure air controls a fuel pressure regulator, allowing fuel, such as propane, to enter the system from a fuel canister. The air and fuel of controlled volume are permitted to mix and flow together into a catalytic combustion chamber where combustion is initiated by a spark generator.

Such a combination, if positioned with the reflector aperture substantially horizontal and with a North-South disposition of the reflector axis, or with the reflector aperture vertical, its axis substantially vertical and with a Southern exposure of that aperture, will produce effective sun-tracking and efficient heating of the fluid in the tube throughout the daylight hours even though the reflector remains static.

Abstract: A solar heating device for heating a liquid used in the device as the refractive medium. A lens and a heat absorbing member carry the liquid and are connected together so that the liquid may be communicated therebetween. The lens concentrates the solar energy on the heat absorbing member when the lens is full of the liquid, thereby increasing the temperature of the liquid in the heat absorbing member. In a failure condition where the liquid is drained from the heat absorbing member, the liquid also is drained from the lens, decreasing the refraction of the solar energy focused by the lens on the heat absorbing member and thereby decreasing the temperature of the heat absorbing member to avoid a fire.

Abstract: A distensible body having an air impervious bladder of stretchable material is connected to a compressed air source and to a pressure indicator by hoses. A squeeze bulb and a releasable check valve pumping air into the body force the stretchable bladder to distend. The bladder pressure is shown on the pressure indicator which can be entirely mechanical or can include electronic components providing a digital display of such pressure.When relaxed, the body is inserted into the vagina and then the body bladder is distended until it engages the vaginal wall. The elasticity of the vaginal muscles is measured by noting the increase in bladder pressure indicated as more air is pumped into the body. Controlled exercise of the vaginal muscles is effected by alternately distending the body bladder to exert a predetermined amount of pressure on the vaginal wall and releasing the pressure by allowing air to escape through the releasable check valve.
