Title: Improvements in or relating to circuit controlling devices, particularly applicable to electric refrigerators
IPC: F25B49/02
Filed: 1934-11-16
Abstract: 434,064. Thermal switches; automatic circuit-breakers, IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London. (Assignees of Kuhn, C. W. ; 12th Street, St. Paul Avenue, Milwaukee, Wisconsin, U.S.A.) Nov. 16, 1934, No. 33026. Convention date, Jan. 29. [Class 38 (v)] A circuit-controlling device for an electrically operated refrigerator, comprises fixed contacts 8 adapted to co-operate with a movable bridging contact 10 on an arm 12 pivoted on a fixed bracket 11 and connected by a tension spring 14 to a second arm 13 pivoted at an adjacent point on the bracket 11. A knob 6 is connected by a slide 32 to the arm 13 so that by moving the knob 6 axially the circuit can be opened or closed with a dead-centre snap-action. The switch is also operated automatically by means of a temperature sensitive bellows 70 operating against an adjustable spring 73 to turn a lever 72 about a pivot 79. The lower end of lever 72 carries a point 194 which bears on a spring 88 the other end of which bears on the end 93 of a lever 90 pivoted at 89. From the open position shown, if the bellows expand, the point 94 moves to the right across the point 89 thus moving the point 93 rapidly to the left to withdraw a plate 96 from engagement with contact 10 which then closes under the action of spring 14. On contraction of the bellows the reverse action takes place to open the circuit. The circuit is also opened on overload by a member 46, Fig. 7, biassed to the left by a spring 56 and having a latch 57 which engages a toothed wheel 53 normally held stationary by fusible metal surrounded by a heating coil 48, Fig. 2, connected on the driving circuit. On overload the metal fuses to release the latch 57 and the member 46 moves to the left, Fig. 7, due to spring 56 to engage spring 14 and open the circuit even if the knob 6 is held in the on position as shown in Fig. 7. The device is reset by pulling out knob 6 and pushing it in, the plate 46 being arranged so as to tilt on passing a fixed projection 54 which disengages it from the knob 6 before the circuit is remade. This ensures that the device cannot be reset until the fusible metal has set.

Title: Method of treating polyester polymer materials to improved their adhesion characteristics
IPC: G11B5/702
Filed: 1962-08-29
Abstract: Polyester surfaces are activated by treatment with a solution comprising 0.31-0.57 mol per cent sodium dichromate, 33.4-54.3 mol per cent sulphuric acid, and the balance water, followed by rinsing with water.  Treatment may be effected by immersion in the activating solution for at least 5 seconds, followed by rinsing in water and then immersing in water at 48-100  DEG C. for at least 30 seconds. Polyethylene terephthalate surfaces may be immersed in an activating solution at 40-80  DEG C. for at least 5 seconds. After rinsing in water, the rinsed polyester surfaces may be treated with an aqueous alkaline solution having a sodium hydroxide concentration of at least 2.49 moles per litre, preferably maintained at at least 80  DEG C. In a preferred method, the polyester surface is immersed in the activating solution at 70-95  DEG C. for at least 5 seconds, rinsed in water, and then contacted with the aqueous alkaline solution for at least 5 seconds, the alkaline solution having a temperature from 70-100  DEG C. Such treatment improves the adhesion properties of the surface for binders employed in magnetic oxide coatings, and for metals, e.g. copper, tin, nickel and silver, deposited by electroless techniques.  Polyester surfaces of non-uniform quality may be similarly treated under more closely-controlled conditions. Surfaces so treated may then be sensitized with stannous chloride and palladium chloride solution, and a nickel layer plated thereon.

Title: Improvements in or relating to colour television receivers
IPC: H04N9/455
Filed: 1961-09-15
Abstract: 941,630. Colour television; valve and transistor monostable gating circuits. E. K. COLE Ltd., and P. A. TINGEY. Aug. 24, 1962 [Sept. 15, 1961], No. 33090/61. Headings H3P, H3T and H4F. In an N.T.S.C. television system the colour burst signal is separated from the back porch of the line blanking period of the chrominance signal by means of a thermionic valve (or transistorized) monostable multivibrator which is triggered to its unstable condition by a pulse derived from the line synch. pulse and whilst in this condition the conducting valve or transistor constitutes the burst amplifier. As shown, the monostable multivibrator comprises valves V1, V2 with V1 normally " off" and V2 conducting. A negative going line synch. pulse appearing at the anode of the synch. separator valve V3 is differentiated by the network C1, R1 and the trailing edge of the differentiated pulse triggers the multivibrator. The time constant of the multivibrator is determined by the network R4, C6 and is made equal to the minimum duration of the back porch of the chrominance signal which signal is applied to the terminal A with the separated colour burst appearing across the secondary winding of the transformer T. The circuit C3, L1, tuned to the colour sub-carrier frequency ensures a low grid-cathode impedance of the conducting valve V1, thus effectively reducing the amplitude of the burst signal.

Title: Automatic position-control system
Inventor: EVANS DAVID SILVESTER
IPC: H03M1/00
Filed: 1955-11-18
Abstract: 798,193. Electric selective signalling; electric correspondence control systems. HILGER & WATTS, Ltd. Nov. 16, 1956 [Nov. 18, 1955], No. 33113/55. Class 40 (1). A shaft control arrangement includes two different control systems: an analogue system using two identical tapped potentiometers P1, P2, Fig. 1, a servomotor M being adapted to bring a slider OS to a balanced position approximately corresponding to that of a control slider IS and a digital system in which cam-controlled contacts IC, Fig. 2, provide signals on a combination of lines, the servomotor also driving a coded commutator C to energize a combination of relays Ra-Rd the contacts MC of which are connected to contacts IC so that when the shaft controlled arrives at the precisely correct position a relay RLS is energized to switch off the servomotor and apply braking. The slider IS, Fig. 1, is set by a knob K which also sets the cams Ca-Cd controlling the contacts ICa-ICd. The servomotor is controlled by an error indicator EI in dependence on the error signal, i.e. the difference of potential between the tappings contacted by the sliders IS and OS. The servomotor would tend to overshoot the balanced position and oscillate about it if the digital system did not apply a positive stopping control. In another form the two systems are combined by replacing the servomotor-controlled slider OS by a decoding network of relay contacts, the relays for which are controlled through the coded commutator C. At each position of the controlled shaft the commutator picks up a combination of relays the contacts of which apply to the error indicator EI a voltage from a corresponding one of the tappings of potentiometer P2 for comparison with the voltage on the tapping selected by the control slider IS. Both systems operate in the same manner as before. Where selection on more than one digit is required an analogue and digital system is provided for each digit and automatic means are provided to bring them into operation in succession, e.g. starting with the thousands digit and ending with the units digit. In this case the coding commutator may be replaced by photo-responsive devices controlled by a transparent coded disc.

Filed: 1935-12-03
Abstract: 466,780. Television. GENERAL ELECTRIC CO., Ltd., and EDWARDS, G. W. Dec. 3, 1935, No. 33415. [Class 40 (iii)] To compensate for the trapezoidal distortion introduced by scanning by means of a Nipkow disc, a keystone-shaped image of a rectangular object is projected on to the disc by means of an optical system comprising one or more curved reflecting or refracting surfaces. In the arrangement, shown in Fig. 1, an image of the rectangular gate 2 through which a film 3 is drawn is projected by lenses 4, 4<1> on to a cylindrical reflector 5, the axis of which is inclined to the axis of rotation of the scanning disc 6. The image reflected on to the disc is distorted into the shape shown at b. To correct for the decrease in illumination of the wider part of the image, an absorbing wedge 8 may be suitably inserted in the optical projecting system. The curvature of the curved sides of the image is determined by a suitable choice of the curvature of surface of the reflector 5, and the angle between the other sides of the image is determined by adjustment of the axis of the reflector relatively to the disc. A conical reflector may be used, and may be adjusted to vary the curvature of the effective surface, and hence the curvature of the image. The reflecting surface may be the outer surface of a solid body or the inner surface of a transparent tube. Fig. 4 shows a glass slab with a flat surface on which light is incident, and a curved reflecting surface. The use of a refracting prism 1 for producing a keystoneshaped image A<1> of a rectangular object A is shown in Fig. 7.
