Title: Improvements in and relating to starter switches for electric discharge lamps
Inventor: NERLINGER PETER
IPC: H05B41/08
Filed: 1967-10-18
Abstract: 1,203,249. Thermal switches. BERLINER GLUHLAMPEN-WERK VEB. 18 Oct., 1967, No. 47384/67. Heading H1N. A glow-type starter switch for electric discharge lamps, more particularly fluorescent lamps, comprises a bi-metal electrode so arranged that the glow discharge on the bimetal electrode takes place mainly on the bimetal component with the lower coefficient of expansion and the bi-metal component with the higher coefficient of expansion is mainly heated by conduction from the component with the lower coefficient of expansion rather than directly by the glow discharge. Thus the bimetal electrode has an increased amount of heat at the moment of closing as a result of which the duration of the closed contact condition is extended. One or both of the bi-metal components may be covered with materials such that the bi-metal component with the higher coefficient of expansion exhibits the higher cathode drop. This bi-metal component may be covered with a layer which is non- gassing, electrically insulating and heat resistant, such as Al 2 O 3  or SiO 2 , by electrophoresis, by metallizing or other process. Alternatively this bi-metal component may be screened in its at-rest position by a covering which does not follow the deflection of the bi-metal such as nickel or ceramics. The bi-metal electrode may be in the form of a hairpin. The legs of the hairpin may be prestressed at normal temperature if the bi-metal is to operate at a higher than normal ambient temperature. The bimetal electrode may be straight and two may be provided to work together, or it may be in beta form. The electrodes may be welded to their current supply members.

Abstract: 1410646 Brush gear A B SHAPIRO V P CHERNYAVSKY and I A KADIOGLY 17 Oct 1972 47795/72 Heading H2A Variations in the current flow at a brush 2 as a consequence of variations in the contact resistance between the brush and a slip ring (not shown) are reduced by connecting a resistive steel pipe 4 in series between a conducting bus 5 and a flexible copper lead 3 for the brush, the resistance of the pipe 4 being comparable with the contact resistance at the slip ring. Dissipated heat is removed by a liquid coolant which is passed in succession through a pipe 7, a resilient insulating pipe 6, and steel pipe 4. A brush holder 12 is fastened to bus 5 by bolts 8 and a plate 9, a set of spacers 10 and bushes 11 serving to insulate the holder from the bus. In a further arrangement (not shown), the brush is connected to the bus by a flexible resistive conductor, e.g. steel, in a resilient pipe through which coolant is passed, the resistance of the conductor being likewise comparable with the contact resistance at the slip ring. The technique of using resistive leads may also be applied to parallel connected brushes (no details) to reduce variations between respective current paths.

Filed: 1967-10-20
Abstract: 1,197,506. Lasers. WESTINGHOUSE ELECTRIC CORP. 20 Oct., 1967 [15 Nov., 1966], No. 47855/67. Heading H1C. In a solid laser the laser rod and pumping lamp are positioned in a reflecting pump cavity through which a cooling fluid flows. A neodymium doped laser rod 32 is inserted at one end in a tight fit relation within an aperture 36 extending through a stainless steel base member 14 and a flash lamp 42 has a terminal 44 projecting from one end which is inserted in aperture 46 in base 44 and a terminal 50 at the other end connected to a terminal connector 70 passing through an insulating cylindrical terminal member 56. The rod 32 and lamp 42 are enclosed by a glass cylindrical enclosure 20 sealed between the base member 14 and terminal member 56, which enclosure 20 forms a pump cavity and is coated on its outside surface with a layer 52 of highly reflective material which reflects and directs the pumping light on to laser rod 32. The coating 52 is protected by a glass coating 54. In order to cool the laser a cooling medium such as water is directed by a pump into inlet 88 through the cavity formed by housing 20 and out through outlet 86 whence it circulates through a reservoir and heat exchanger. Silicone liquid may be used instead of water. The cooling liquid also serves to filter out the unwanted ultra-violet radiation from the pumping lamp 42 and to this end the layer 52 may be of silver which allows the ultra violet radiation from the lamp 42 to be transmitted therethrough and not reflected. The glass of which housing 20 is made may also act as a filter. In a further arrangement, Fig. 3 (not shown), a diffused reflector is formed by a reflective powdery material which is packed between the enclosure 20 and a second cylindrical enclosure having a slightly greater diameter and made of glass or plastics material. This arrangement allows uniform pumping.

Abstract: 1,272,693. Measuring fluid-pressure electrically. BENDIX CORP. Oct. 14, 1970 [Oct.22, 1969], No.48831/70. Heading G1N. A fluid-pressure transducer comprises a bimetallic diaphragm 9, Fig. 1, subjected to the test pressure P to vary the output of a differential transformer 23 accordingly, the output signal being used to energize a local heater 63 which causes the diaphragm to return to its original position, and the temperature at which this occurs is indicative of the pressure P. The diaphragm 9 separates two sealed chambers 11, 13, the latter containing the differential transformer 23 having two sets of secondary windings each with an independent core. The test pressure P determining the air-gap 25 between the transformer and the diaphragm varies the reluctance of one magnetic circuit and the voltage induced in one set of secondary windings. The voltage difference between the two sets of secondary windings is amplified at 43, rectified at 61 and fed to thermoelectric device 63 which heats or cools the diaphragm 9 and its support 1 until a balanced condition is attained. The temperature at which this occurs is sensed by a probe 67 to provide a signal voltage corresponding to the pressure P. In another embodiment, Fig. 4, the diaphragm 73 carries a switch contact 85 which co-operates with a fixed contact 87 to energize a heater 77 when the test pressure P flexes the diaphragm downwards. The temperature rises until the contacts 85, 87 open, and the temperature at balance is measured by a probe 93. Cooling is effected by the upper member 79 acting as a heat sink.
