May 30, 1935, No. 15768. [Class 38 (iv)] In the automatic steering of aircraft, ships, and the like wherein a pair of electric relays causing operation of the steering gear in alternate directions is controlled by photoelectric means in accordance with light passing through a slotted compass card, a single photo-electric cell P is connected to a galvanometer R1, the needle of which switches on one relay or the other according to the sense in which the cell illumination fluctuates from a mean value. The compass card and compass bowl are each provided with windows transmitting the light from a lamp L to the cell, and the window 10 in the card is elongated peripherally of the card. The motor M controlled by the relays, in addition to operating the steering gear, turns the casing of the compass in such a way as to maintain the compass bowl at a given angle relative to the cardinal compass points. The apparatus may be used for graphical registration of the movements of the rudder and the course or directions of the vessel. In an aeroplane the steering member 14, Fig. 4, is rigidly connected with the steering segment 13 and a wheel 12 is loosely mounted on its shaft and actuated by the steering motor shaft 15 which also drives the compass casing 1. A friction clutch couples the wheel 12 with the steering gear and may be maintained in engagement by a spring so long as the member 14 is not pressed down.

Title: Improvements in or relating to the sealing of tins and like containers
IPC: B23K1/00
Filed: 1942-11-09
Abstract: 559,131. Closuring containers. FRASER & SON, Ltd., J., and ROBINS, W. H. Nov. 9, 1942, No. 15828. [Class 125 (ii)] [Also in Group XXII] Soldering.-A tin or like container filled with dry foodstuffs and having its lid sealed thereon except for a small opening, has the opening closed, such as by soldering in a chamber from which air pressure is reduced considerably below atmospheric and the chamber charged with an inert gas to a pressure substantially above atmospheric prior to closing the opening. The containers are placed in a chamber 10 with one or more gas-tight doors 11. The top of the chamber has a swelling 18 with windows 19, 20 and a universal joint 21 for an electrically heated soldering iron 22, packing such as a gland or one or more slip-washers being provided to maintain the joint in a fluidtight condition irrespective of whether the internal pressure is below or above atmospheric. A multi-way valve 24 connects the chamber 10 either to a vacuum pump 25 through a pipe 26 or to a cylinder 27 of inert gas such as carbon dioxide or nitrogen by a flexible pipe 28. The valve 24 may also be arranged to connect the chamber with the atmosphere or a normally pliable release valve may be used. A pressure gauge 36 is also provided. Water vapour given off during evacuation may be condensed by a condenser in the pipe 26. A rack 31 secured to the chamber may support a number of gas cylinders. The gas is fed at a pressure greater than atmospheric so that the chamber can be charged with gas to a pressure say one or two lbs. per sq. in. above atmospheric. When using carbon dioxide the gas may flow into the chamber from a low-pressure cylinder fed from a highpressure cylinder through a pressure reducing valve so as to avoid excessive frost. Nitrogen is used direct from a high-pressure supply, being controlled by a valve 32. Large chambers may be provided across the top and sides with a number of soldering-irons. The tins become bulged by the gas and may be tested for leaks by immersing in a liquid and leaky tins may also be detected in store due to loss of the bulged shape.

Title: Improvements in methods of and means for processing textile fibrous material
Inventor: GREENWOOD FRANK ALFRED
IPC: D01G23/06
Filed: 1961-05-02
Abstract: 930,873. Combining card slivers. T.M.M. (RESEARCH) Ltd. April 30, 1962 [May 2, 1961], No. 15923/61. Classes 120 (1) and 120 (3). [Also in Group XXXV] Variations in the thickness of a sliver 101 of textile fibrous material comprising the combined outputs of two or more carding machines A ... D are corrected by adjusting the feed to one of the machines. The thickness is measured by tongued and grooved rollers 14, 15, one of which is mounted on a pivoted arm whose movement either varies the output of a differential transformer or operates contacts. In either case a reversible servomotor is driven in the appropriate direction when the thickness departs from a preset standard, the motor either adjusting a variable gear, e.g. cone pulleys, in the feed roller drive of one machine A (Fig. 4, not shown) or varying the opening between plates in a feed hopper (Fig. 5, not shown). Correction is made in accordance with integrated error, since the servomotor is run for the whole time that the error persists. If the deviation is excessive the servomotor is witched off and a signal may be given. Specification 886,396 is referred to.

Abstract: 457,853. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. June 4, 1935, No. 16059. Convention date, June 6, 1934. [Classes 40 (iii) and 40 (v)] Synchronizing signals are separated from the picture signals by an amplitude filter comprising a gas-filled discharge tube 5, the bias on which is adjusted manually and automatically by the mean value of the synchronizing signals. The automatic adjustment of the bias is obtained by a high resistance 13 bridged by a condenser 12 which gives to the circuit a time constant greater than the period of several complete scannings. The tube 5 may have a heated cathode. The line and frame synchronizing signals are separated by resonant transformers or chokes 9, 10 tuned to the frequency of the signals and with their coils damped by resistances 14, 15. The transformers are so arranged that positive impulses are fed to the associated relaxation oscillators. The negative bias across the circuit 12, 13 is also used to control the grid bias of an amplifying-valve prior to the separation of the synchronizing-signals, Figs. 3 and 5 (not shown), or as an additional bias for the discharge tubes of the relaxation oscillators.
