Title: Improvements in or relating to flash-light lamps
IPC: F21K5/08
Filed: 1941-08-23
Abstract: 549,136. Flash lamps for photography. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Aug. 23, 1941. No. 10781. [Class 9 (ii)] In flash light lamps which contain a solid combustible material such as aluminium or aliminium and magnesium foil or wire, which reacts actinically with oxygen inside a bulb, the gas filling comprises a mixture of oxygen and nitrous oxide gas containing from 10 to 60 per cent. by volume of nitrous oxide gas. This is stated to lengthen the flash time and to increase the time lag, i.e. the time which elapses between the establishment of the ignition current and the commencement of light development, but this latter may be reduced by increasing the gas pressure from say 23 c.m's to 35 c.m's.

Title: Synchronous permanent magnet ac motors
IPC: H02K21/14
Filed: 1973-03-07
Abstract: 1376284 Synchronous motors AMF Inc 7 March 1973 [24 March 1972] 10986/73 Heading H2A  The rotor 20 of an A.C. synchronous motor is rotatable relative to a shaft 26 and carries a pivotally mounted stop member 24 which, on rotation of the rotor in the undesired direction; engages an abutment 18 on the stator and so reverses the rotor, and, on rotation of the rotor in the desired direction, couples the rotor to the shaft so that the two rotate in unison. The motor shown has interdigitated stator poles 14, 16 and a rotor permanent magnet 21. The shaft 26 carries a cam having a leg portion 28. On clockwise rotation of the rotor, the narrower end of the stop member 24 engages the leg 28 of the cam and its point 25 engages abutment 18 to first stop and then reverse the rotor. On initial anti-clockwise rotation of the rotor, the blunt end of stop member 24 engages the leg 28, the sharp point 25 is retracted within the rotor circumference and the rotor is free to rotate, the stop member 24 and the cam then forming a mechanical coupling between the rotor and shaft. In a modification, Figs. 5, 6 (not shown), the cam has two leg portions (36, 37), and the stator includes, several abutments (32), this construction reducing initial rotation of the rotor in the undesired direction or, when the rotor initially rotates in the desired direction, reducing the amount of lost motion of the rotor before the rotor movement is transmitted to the shaft through the stop member and cam.

[Classes 83 (ii) and 83 (iv).] Fishplates 9, Fig. 11, for the joints of rails 10, and which become worn about the middle are heated and pressed between dies 32 which thin the web 9a and flange 7a about the middle, and force the top and bottom bearing surfaces up and down respectively to take up the wear. The dies are so proportioned that this thinning merges into tapering to the original thickness at the ends of plates. When the rails themselves are worn also, the fishplates arc pressed to give extra height and depth about the middle or crowning as in Fig. 9 to take up wear. Fig. 17 shows a modification in which the plates are pressed in at 41, 42, 43 to provide surplus metal to take up the wear. Other modifications are shown.
