Filed: 1974-01-31
Abstract: 1454269 Measuring speed XEROX CORP 31 Jan 1974 [2 Feb 1973] 4450/74 Heading G1N [Also in Divisions G3R and H2J] A method of measuring the speed of a motor by periodically interrupting the supply current thereto and sampling the emf induced in the rotor once the transients consequential upon interrupting the supply current have decayed, is characterized in that the current through the motor is forced to decay at a rate which is faster than the intrinsic rate of decay determined by the inductance and resistance of the motor armature. This is attained, see Division H2, by limiting the back emf to a maximum value set by a Zener diode. The arrangement forms part of an automatic speed-control system, see Division G3, for a tape recorder motor.

Abstract: 270,435. Easting Windscreens, Ltd., and Willard, R. C. Feb. 16, 1926. Windscreens. - In an arrangement for tensioning the celluloid panel of a vehicle window or windscreen for the purpose of preventing buckling, a complete four-sided frame or support, to which the panel is detachably connected, is formed of rigid members, which are so jointed together that the frame is extensible in at least one direction and are adapted to house springs tending to tension the panel in all directions simultaneously. In the construction shown in Fig. 1, the side members 5 - - 8 of the frame are of non- circular cross-section and are telescopically jointed together by four L-shaped corner members 1 - - 4 provided with recesses containing four springs 9, each side member abutting at one end against a fixed pin 10 and at the other end against a spring 9. The celluloid panel 30 is provided at each of its corners with metal plates which are connected to the corner pieces 1 - - 4 by screws or bolts 35. The lower horizontal member 8 of the frame is supported by fixed spigots 36 or by adjustable spigots 46, Fig. 9, carrying U-shaped clips 44, which embrace the frame member and allow the frame to be horizontally adjusted in its own plane. In a modification, Fig. 7, an extension of the frame in the vertical direction is obtained by arranging the vertical frame members 11 to telescope in corner brackets 18, while the horizontal tensioning of the panel 38 is effected by connecting the panel to four slides 20 carried by the cornerpieces and pressed outwardly by springs 25. When attaching the panel to the slides, a key is employed to press the slides inwardly against the effect of the springs 25, while the other springs 19 can be compressed by hand pressure. In another construction the frame is formed of two U-shaped members pressed apart by springs to give the vertical tensioning, and carrying four corner springs to which the celluloid panel is attached for obtaining the horizontal tension. In a still further modification, the frame comprises four L-shaped members telescopically connected to each other at the centre of each side of the frame.
