Title: Improvements relating to railway traffic controlling apparatus
IPC: B61L13/04
Filed: 1945-07-30
Abstract: 580,599. Railway signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. July 30, 1945, No. 19440. Convention date, Aug. 1, 1944. [Class 105] For detecting the presence of a train in a stretch of track and so controlling the release of a signal under either a manual control or a centralized traffic control system ultra high frequency current generated at one end is radiated as a beam at vehicle height along the track to operate a receiver and relay at the other end whereby an ultra high frequency beam (of different frequency or different modulation) is radiated in the return direction to operate a receiver and relay thereby to permit clearance of a wayside signal provided.no train is present to prevent the two receivers responding to the respective ultra high frequency beams. Where the track curves or the gradient changes, reradiators are provided. The radiating and receiving antennae shown as simple vertical dipoles (for vertical polarization) are mounted on the signal masts with metallic shields to prevent backward radiation; their associated generating and detector-amplifier apparatus are preferably also housed on the mast to shorten the connecting cable which is of coaxial form for each antenna. To clear a signal for eastbound movement from the passing-siding location PS1 a centralized traffic control relay SR1 is energized in the usual manner. Front contact 12 of this relay energizes a transmitter OS1 and antenna TE which radiates a beam (of 3 metres or less wave length) along the stretch of track to the next passing-siding location PS2 where a detector-amplifier receiver DA2 is operated to energize a relay 13 whereby with the westbound signals LA, LB at location PS2 being at danger to close detector contacts 15, 16, the transmitter OS2 and antenna TW at location PS2 is energized from a source B. over these contacts 15, 16, front 14 contact of the relay 13, and back contact of unoperated centralized traffic control relay SR2 at location PS2. Thus a return beam is radiated along the track to operate a detectoramplifier receiver DA1 whereby a relay 25 is energized to clear an eastbound signal RA or RB as selected by a points detector over a circuit from a cource B, front contact 17 of centralized traffic control relay SRI, front contact 26 of the relay 25, and points detector contact SW1.18 in one or other position. The stretch of track is shown as having intermediate re-radiators 8, 9 for the beam transmitted from antenna TE and re-radiators 10, 11 for the beam transmitted from antenna TW, the beaming being directed across the track at a small angle with the support posts arranged alternately on opposite sides of the track.

Abstract: 1,149,092. Photographic cameras. EASTMAN KODAK CO. May 5, 1966 [May 6, 1965], No. 19954/66. Headings G2A and G2E. A photographic or cinematographic camera has means for securing the leading end of a film on a take-up spool 2 of the camera, the means being connected with the film winding mechanism and a rewind device so that actuation of the former causes closing of the securing means and actuation of the latter causes opening thereof. The film leader is pushed loosely into a slot between surfaces 2a of the spool and 4b of a cheek or jaw 4 pivotable about the take-up spool spindle 1. Actuation of the film winding mechanism rotates a wheel 7 on the spindle so as to displace a spring-biased lever 9 out of contact with the reduced portion 1a of the spindle, thereby allowing a spring 5 to move a slide member 6 and the spindle 1 in the direction opposite to A. At the same time, the spring 5 pivots the cheek 4 anti-clockwise (as seen) to clamp the film leader between the surfaces 2a and 4b. The lever (9) now rests against an enlarged portion of the spindle (1) Fig.2 (not shown). To engage a rewinding device, (not shown) a knob 1b and hence the spindle 1 and slide 6 are displaced in the direction A, thereby causing surfaces 6a, 6b of the slide 6 to enter between the surfaces 2a, 4b and pivot the cheek 4 clockwise to the position shown, thus freeing the film leader for rewinding.
