Title: Improvements in apparatus for winding paper webs
IPC: B65H19/22
Filed: 1931-12-15
Abstract: 379,585. Winding webs. KRUIMEL, J. H. A., 20, Hooge Duin en Daalschweg, Bloemendaal, Holland. Dec. 15, 1931, No. 34732. [Class 100 (i).] In a machine for winding paper webs, the web is first attached to a roll 3 mounted by means of trunnions in open bearings 6 carried by a frame 20 which is acted on by springs or by a weight 9, via a cord 10, pulley 11, pinion 13, and rack 14, so as to press the roll 3 towards a winding-drum 1. As the paper is wound and the roll increases in diameter, the trunnions are released from the bearings 6 and are received in other open bearings 16 in levers 15 which normally rest by gravity in the position shown with a projection 19 bearing against a stop 18. The increase in diameter of the roll causes the levers 15 to move to the position shown in dotted lines and the winding is stopped and the levers 15 held by a bolt while the wound roll is removed by a crane. As soon as the roll is released from the first set of bearings, the frame 20 moves to the right under the action of the weight 9 so that the bearings are returned to their original position for taking up a fresh roll to enable the winding to be continued with little interruption as soon as the wound roll is removed.

Title: Improvements relating to circuit arrangements for encoding or decoding stereophonic signals
IPC: H03D1/22
Filed: 1964-08-26
Abstract: 1,073,478. Stereophonic broadcasting systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Aug. 26, 1964 [Sept. 5, 1963; Nov. 20,1963; April 1, 1964], No. 34860/64. Heading H4L. In a receiver or transmitter for stereophonic signals of the type in which an audio-frequency A + B signal is transmitted together with a subcarrier which is suppressed carrier amplitude modulated with the A - B signal, two transistors are arranged to conduct alternately at the subcarrier frequency to effect appropriate switching of the two stereophonic channels. At a receiver, Fig. 1, the composite signal after detection is supplied to a transistor 1 and a 19 kc/s. pilot signal is selected at 5, frequency doubled by diodes 6, 7, and amplified by transistor 8 to reconstitute the 38 kc/s. subcarrier. The composite signal in the emitter circuit of transistor 1 is supplied via transistor 2 to the emitters of the two switching transistors 3, 4, the base circuits of these transistors being supplied with opposite phases of the 38 kc/s. subcarrier or switching signal. Since the composite signal is equivalent to a series of amplitude-modulated pulses alternate pulses being of opposite polarity and representing the A and B signals respectively the A signals appear at point a and the B signals at point b. To reduce cross-talk a predetermined portion of the A+ B signal derived from resistor 12 is supplied via resistors 10, 11 to the points a, b respectively. Rejector circuits 13, 14 suppress the subcarrier signal and the RC circuits following provide de-emphasis. In the absence of a subcarrier both transistors 3, 4 are fully conducting so that a monophonic signal is supplied to the outputs A, B without additional switching. In modifications, Figs. 2 to 5 (not shown) each channel includes a pair of transistor switches connected so that the subcarrier cannot reach the outputs A. B, and the filters 13, 14 may be dispensed with. In some of these arrangements special switching is required for the reception of monophonic signals as the transistor switches are non-conducting in the absence of the subcarrier signal. If the input and output circuits are interchanged the arrangement may be used for providing a composite stereophonic signal for the modulator of a transmitter, Fig. 5 (not shown).
