Aug. 14, 1933, No. 22698. [Class 39 (i)] A discharge lamp is mounted within a jacket and the free end of the lamp is registered with respect to the jacket by means of a Z- shaped spring support 1, Fig. 1, the curved ends of which are adapted to engage the inner surface of the jacket. The support is formed of the material known under the Registered Trade Mark "Nichrome," and is secured to two anode leads 2 which project from the end of the lamp bulb.

Patent GB-1048035-A (GB)
Title: Improvements in or relating to power supply circuits
IPC: G05F1/573
Filed: 1963-06-10
Abstract: 1,048,035. Automatic voltage control. H. WELLHAUSEN.June 10, 1963 [June 9, 1962], No. 22963/63. Heading G3R. [Also in Division H3] In a voltage regulator of the series transistor type, the main transistor is protected against excessive power dissipation by a circuit which is connected across the collector and base of the transistor and which comprises the series combination of a resistor carrying the load current, a second resistor, and a voltage-dependent element. As shown, a voltage regulator supplying a load 2 includes a main transistor 1 and a resistor 9 connected between the collector of the transistor and the load. The end of resistor 9 remote from the collector is connected over a resistor 11 and a Zener diode 10 to the base of transistor 1. When a certain current is exceeded, the voltage drop across resistor 9 and the voltage drop across the collector/emitter circuit of transistor 1 are together sufficient to render Zener diode 10 conductive so that a base current flows in the transistor; on a further increase in current, e.g. on overload or short circuit, this base current causes the collector/emitter voltage to fall, so that most of the input voltage is dropped across the resistor 9 which is so dimensioned that the maximum transistor current is not exceeded even on short circuit. The transistor 1 is thus protected against damage; a fuse can be connected in circuit to protect the supply source. The regulator may include a further Zener diode connected across the collector/base circuit of transistor 1 and an amplifying transistor connected to the base of the transistor (Figs.4 and 6, not shown).

Abstract: 598,706. Engine-starting jacks. GENERAL MOTORS CORPORATION. Sept. 6, 1945, No. 22976. Convention date, Sept. 16, 1944. [Class 78(iii)] [Also in Group XXVII] A starting jack 1 has a handle 21 and two pawls 25, 27, which, as the jack is oscillated about the fulcrum tube 15 resting in the guide member 3, alternatively engage the openings 29 in a fly-wheel 5 of an internal - combustion engine and so impart rotary motion to the said engine. The pawls are pivoted at 23 on either side of the fulcrum 15 and their ends are so designed as to free themselves from the flywheel when the engine starts. Counterrotation of the engine is prevented by the simultaneous engagement of both pawls in the fly-wheel. A bracket 3 may be supplied on either side of the engine for starting it in either direction.
