Title: Double reflector motor vehicle headlamp with anti-dazzle device - uses twin parabolic reflectors, one set around one end of lamp bulb and other round other end, to ensure all rays are focussed
IPC: F21V7/00
Filed: 1983-04-26
Abstract: The headlamp uses a double reflector to control the top of the beam to ensure oncoming motorists are not dazzled by light from the headlamp. The light source is treated as being made up of two parts, representing the extremities of the lamp bulb. One end of the bulb is situated in an imaginary half-cone generated by a right segment passing through the focus and the periphery of the first reflector, while the other end of the lamp bulb lies in a similarly defined half-cone associated with the second reflector. This arrangement ensures that all the generated light rays are concentrated into a parallel beam, preventing the spread due to the extended light source which occurs in conventional lamps.

Abstract: ABSTRACT OF THE DISCLOSURE            Concentrated fluid dispersions of amphipathic block or graft copolymer in a hemi-solvent liquid are converted to homogeneous solid masses by heating to a temperature above the glass transition temperature of the components of the copolymer which are insoluble in the hemi-solvent, and then cooling to below that temper-ature.  The process is suitable for coating and potting techniques.

Abstract: ABSTRACT OF THE DISCLOSURE           A system for isothermally separating one component from a fluid mixture to produce a breathable fluid by alternately presenting the fluid mixture to first and second beds of adsorbent material.  A control valve adjacent each of the beds will admit the fluid under pressure from a compressor and a storage reservoir to rapidly build up the pressure in the selected absorbent bed of material.  The beds of adsorbent material are interconnected by a first conduit through which the fluid under pressure is communicated, a second conduit through which the product effluent flowing from the selected bed after retention of one component of the fluid mixture is communicated to the other bed for removal of the one component therefrom by flowing to the atmosphere, a third conduit for equalization of the fluid pressure is the first and second beds upon switching from one bed to the other, and a fourth conduit through which the product effluent is carried to a storage reservoir for use as a breathable fluid.  A timing mechanism is connected to a manual control which automatically switches the operation of valves in the fluid mixture supply line in a first mode of operation is prevented from operating in a second mode when positive pressure breathing is desired by an operator.

Abstract: TRANSIENT SUPPRESSION FOR TAPE PLAYERS    INTEGRATED CIRCUIT PREAMPLIFIER                   Abstract of the Disclosure In a tape player the preamplifier integrated circuit can produce a transient, when the player is turned off, that will impress itself on the head thereby recording a noise signal on the tape.  A circuit is shown for suppressing such transients.    A diode is connected in series with the power supply so that when the player is turned off, the diode disconnects the pre-amplifier from the power supply. In addition a large value filter capacitor is connected across the preamplifier terminals so that the applied voltage can change only at a relatively slow rate.

Abstract: ABSTRACT:           A transmission system for a colour television signal, in particular a system for recording on and re-producing from a record carrier. The chrominance signal is divided into two separate colour signals, which in a line-sequentially alternating fashion are modulated on two separate colour carrier waves. The transmitted or recorded colour television signal can simply be transformed into both a standard PAL and a standard SECAM signal. Owing to the line sequential alternation of the colour signal, colour errors which may arise owing to a mutual difference of the transfer charac-teristics for the two colour signals are automatically, compensated for in the case of reproduction via a PAL receiver.
