Title: Improvements in electric motors intended to work in an explosive medium
IPC: H02K9/24
Filed: 1927-04-19
Abstract: 269,592. Ateliers de Constructions Electriques de Charleroi. April 19, 11128, [Convention date]. Casings; motors, cooling and ventilating.-In a self-ventilating electric motor working in an explosive medium and having inlet and outlet openings provided with flame guards, the possibility of flame passing from inside the machine to the surrounding atmosphere is minimized by mounting the buckets of the internal ventilating fan very close to the flame guards so that their thermal mass plus the current of ventilating air tend to extinguish flames. The fan buckets may be replaced by a screen or blade. In the form shown in Fig. 2, the motor casing has flame-guards A, of miners' safety lamp type, and the fan V, keyed on the shaft H, has its open or tubular buckets C, B close to the suction inlet side of the air openings G. The ribs D between the buckets may be thickened in the circumferential direction so as to be as wide or even wider than the bucket openings. Fig. 4 shows a form in which the fan V<1> is separated from the inlet openings, giving an increased suction chamber, and a blade or screen P carried by the fan or shaft is interposed between the fan and inlets close to the flame guards A. This blade is eccentric to the shaft or is apertured so that it alternately covers and exposes the ends of the flame guards.

Title: Improvements in and relating to optical systems
Inventor: CLOTAR GILBERT
IPC: G02B17/08
Filed: 1956-04-05
Abstract: 802,288. Reflecting optical systems. AMERICAN OPTICAL CO. April 5, 1956, No. 10503/56. Class 97(1) The system comprises two centrally apertured mirrors, one being concave and spherical, aligned with each other and with an object area on the short conjugate side so that one mirror iris receives through the aperture in the second mirror light from the object and will reflect said light toward the second mirror which will in turn re-direct the light through the first mirror's aperture to an image-receiving area on the long conjugate side, and the major portion of the direct rays from the object area to the image-receiving area are blanked out by an, opaque disc, axially positioned between the first mirror and the object area, and by an opaque baffle in the form of a truncated cone. As shown, light from a cathode ray tube 10 is twice reflected by apertured mirrors 12, 13 before passing through Schmidt plates 15 to the image  area. Transmission of direct light is substantially prevented by opaque disc 16 and by conical opaque baffle 17. The diameter of the smaller end of baffle 17 is not greater than that of the disc 16, and the sloping walls of the baffle 17 are substantially parallel to the reflected light rays passing adjacent thereto. The baffle may have a pair of opposed scallops in its smaller end or opposite edge portions of disc 16 may be removed.

Abstract: 106,660. Ansingh, H. K. May 29, 1916. Insulators.-To secure conductor bars 8 in porcelain or like insulating-sleeves 1, the sleeve is provided at each end with a screwed plug 14 engaging an internal screw-thread 13 in the sleeve and 'carrying the conductor with a sliding fit. Holes 11, 12 are formed in the conductor at a distance apart slightly less than the length of the sleeve, into which pins are driven to engage the external faces of the plugs when these are in their correct positions. Only one plug may be formed with a screw-thread; but if both are so formed, one plug is formed with a right-hand thread and the other with a left-hand thread, so that they will move apart or towards each other when rotated in the same direction. In a modified construction, the sleeve is screwed externally and the plug or plugs replaced bv internally screwed caps, or the sleeve is left plain and the screwthreads formed on a metal ferrule secured against rotation on the sleeve. The pins carried by the conductor bars may be replaced by disks or other members 21, Fig. 7, which carry screws 23 for accurately adjusting the conductor relatively to the sleeve.
