Abstract: A safety razor head including a guard member, a platform member fixed to the guard member, a leading blade fixed to the platform member, a cap member, a following blade fixed to the cap member, and flexible bridge portions interconnecting the guard and cap members, the bridge portions extending transversely to cutting edges of the blades and being adapted to permit resilient flexing of the cap member relative to the guard member during a shaving operation.

Abstract: Electronic clocks with analog time displays and a vibrating quartz crystal (1) as a time standard, as well as electronic frequency dividers (6, 7). The display elements are driven by an electronically controlled motor (SM), said motor comprising a power winding (87) and a control winding (68). The control and regulating circuit for the electronically controlled motor (SM) is so designed that only one rpm above the rated rpm is controllably adjustable and, when the frequency of the clock varies, correcting signals are supplied to the AC drive pulses in power winding (87) through a bistable flip-flop (50), said flip-flop being subjected to real pulses derived from frequency dividers (6,7) and pulses derived from motor (SM), a NOR element (58) connected to the output of flip-flop (50) and an additional frequency divider (59), a field effect transistor (88), and a resistor (89).

Abstract: A catalytic heating means is disposed in a heating chamber of a tubular body member defining a hair winding portion. The curling device includes a supply of a liquid fuel and aspirating means for vaporizing the fuel and mixing the vaporized fuel with air to supply a vaporized fuel/air mixture to the catalytic heating means. A self-contained ignition means proximate the catalytic heating means is provided for initiating the oxidation of the vaporized fuel/air mixture in the presence of the catalyst. The catalytic heating means includes a woven sleeve with an unravelled end to act as a flame arrestor and increase ignition efficiency.

Abstract: Electronic game apparatus is provided which is controlled by a person jogging in place to establish a simulated race between a jogger and a simulated competitive runner on the face of a display. The simulated figures give an indication of accumulated input pulses between the jogger and the set rate of the electronic controls.

Abstract: A circuit arrangement for charging a flash capacitor of a designated rated voltage from a DC source of a higher rated voltage. A thyristor in the line from the DC source is blocked when the voltage for which the flash capacitor is designed is reached.

Abstract: Apparatus including polarity sensing means and a switch such as a Triac for providing a ground fault circuit interrupter system for an electrical load such as a hand-held appliance. The Triac is electrically connected in a completed circuit with the electrical load and is positively positioned in series with the line conductor of an A.C. power source. Automatic testing circuitry such as introducing synthetic and counterbalancing synthetic faults to the system is included.

Abstract: A conductive touch grid or plate incorporated in the handle portion of apparatus such as an appliance performs the on/off function of the appliance as well as sensing the impedance of the operator with respect to either the line or neutral side of an associated AC source. Whenever the sensed impedance indicates a potentially dangerous condition a switching element in series with the line conductor interrupts current flow to the appliance thereby protecting the operator.

Abstract: A circuit for igniting an electronic flashtube including a thyristor connected in series with the flashtube and an ignition capacitor connected through a switching thyristor to an ignition transformer to trigger the flashtube. The state of the series thyristor is controlled by means such as an electronic threshold switch to provide proper switching operation over a range of flashtubes with different specimen variations with respect to the time required to build up plasma.

Abstract: A dispenser for use in dispensing a product in heated condition from a pressurized container. The dispenser includes a main housing for removably receiving and holding the container and a heat exchanger assembly mounted in the main housing and spaced apart from the container. The heat exchanger assembly comprises a cup-like mass of a heat conductive material and includes an elongated passageway in its wall of a depth substantially equal to that of the wall and extending from the inlet to the outlet of the heat exchanger assembly. The product is directed in a single predetermined direction through the elongated passageway from the inlet to the outlet of the heat exchanger assembly. Further, an electrical heater is disposed along the inner wall of the cup-like mass and a circuit for connecting the heater to a source of power is provided.

Abstract: A housing has a wall constituted by a rigid metal plate formed with an array of throughgoing perforations and by a flexible synthetic-resin sheet overlying the inner face of the rigid wall and having a multiplicity of projections each extending through a respective perforation and beyond the outer surface of the rigid plate. Futhermore the flexible sheet may be inwardly deflectable to actuate a switch in the housing.
