Title: Improvements in movable electric bridging switch contacts
IPC: H01H1/22
Filed: 1952-10-17
Abstract: 718,234. Switch contacts. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Oct. 17, 1952 [Dec. 27, 1951], No. 26058/52. Class 38(5) A movable-bridging contact 1 is connected to operating arm 5 by a wire stirrup 6 pivoted to the arm and to the contact. The arm 5 is clamped to a shaft 7 by a collar 8 and between the collar and the arm is clamped one end of a U-shaped leaf spring 9, the other end of the spring pressing against the back of the contact and having a cranked extremity 9A received in a groove in the contact back. On closing movement of the arm 5 through an angle a, the contact 1 first engages a fixed contact 3 and then it pivots about the stirrup 6 to quickly engage the other fixed contact 2. On completion of the closing movement through a further angle b, since the stirrup 6 makes an acute angle with the contact 1, a longitudinal thrust is exerted on the contact 1 and the stirrup moves to the position 6A. This action causes the contact 1 to slide over and clean the contacts 2, 3, and the spring 9 is further stressed to increase the contact pressure. A manner of mounting the shaft 7 to permit its easy removal, comprises, Fig. 4, a pair of clamping collars 10, 11 situated at each end of the shaft. Each collar 11 has a hook 12 terminating in a knife edge which rocks on a support arm 13, whilst each collar 10 has a forked extension 7A receiving a rod 17 hinged at 19 to a member 15 fixed to the arm 13. A compression spring 16 bears on the extension 7A through the intermediary of a part-spherical socket 18 and urges the arm 5 to the open position in which the extension 7A abuts the member 15. To remove the shaft 7 each rod 17 is pivoted through 90 degrees to slide the socket 18 over the forked extension 7A. In a modification (not shown) the leaf spring 9 is replaced by a coiled compression spring.

Abstract: 1,086,610. MHD power plant. SIEMENSSCHUCKERTWERKE A.G. June 13, 1966 [June 12, 1965], No. 26328/66. Heading H2A. In an MHD power plant, seeding material (e.g., potassium carbonate) in solid form is fed from a storage container 1 (which may be followed by a grinding mechanism) to a mixer 1b in a heat exchanger 3, where it is heated by the waste gases leaving the MHD generator duct 4. The heating fluidizes (e.g. evaporates) the seeding material and also chemically decomposes it by an endothermic reaction. The seeding material is mixed in solid, liquid or gaseous form with additional combustion air (which may be enriched with oxygen) supplied to the mixer by a compressor 1a. The mixture is supplied as a fluid through a duct 9 to a burner nozzle 11 which is also fed with fuel oil from a storage container 12. The heat recovered from the waste gases by the endothermic decomposition of the seeding material is thus supplied to the combustion chamber 14. If means for recovering the seeding material in liquid form from the waste gases is provided, the recovered material may be sprayed in liquid form into the additional combustion air in the heat exchanger. It is stated to be known to inject a mixture of soft soap and diesel oil into the combustion chamber, whereby an ionized gas is obtained after combustion.

Abstract: 854,295. Radio receiving systems. GENERAL ELECTRIC CO. Ltd. Aug. 26, 1959 [Aug. 15, 1958], No. 26386/58. Class 40(5). In a panoramic radio receiver, frequency marking of a visual display device, for example a cathode-ray tube, is effected by injecting into the received r.f. signal a signal formed by a plurality of component oscillations separated from one another by a common frequency difference F 1 , and injecting into the I.F. signal derived from the received signal a signal formed by a plurality of component oscillations separated from one another by a common frequency difference F 2 , the frequency F 1  being at least twice F 2 . The output of crystal oscillator 12 having components spaced F 1 , e.g. 10 mc/s apart is added in amplifier 4 to the received signal, the intermediate frequency signal being obtained from frequency changer 1 and local oscillator 2. The output of crystal oscillator 13 has components spaced F 2 , e.g. 2 mc/s apart and is added to the output of frequency changer 1. Oscillator 2 is continuously swept through a band, e.g. 10 mc/s. wide, and the frequencies present in the received signal and the outputs of oscillators 12, 13 are displayed as deflections in a CRT trace. The centre frequency of the band swept by oscillator 2 is selected so that a deflection due to oscillator 12 coincides with a deflection due to oscillator 13, thereby effecting calibration. The frequency scale of the trace may be expanded during calibration to facilitate the correct adjustment of oscillator 2. Specification 712,763 is referred to.
