Title: Improvements relating to cathode ray tube beam deflexion circuits
Inventor: EDWARDSON STANLEY MAKINSON
IPC: H03K4/24
Filed: 1959-06-02
Abstract: 874,154. Sawtooth and staircase waveform generating circuits: cathode-ray tube circuits. BRITISH BROADCASTING CORPORATION. March 16, 1960 [June 2, 1959], No. 18853/59. Classes 40(6) and 40(7) A cathode-ray tube deflection circuit comprises a bifilar deflection coil, the elementary windings of which are connected in series opposition across a source of operating potential for a bootstrap circuit, the output terminal of the bootstrap circuit being connected to the junction of the elementary windings and a source of potential being connected in series with the bootstrap capacitor. The circuit shown provides O.1c/s frame deflection for a system in which a television picture is transmitted over circuits having small band width. A linear sweep is provided by charging a capacitor C via resistor R, the charging current being maintained constant by the bootstrap cathode follower V1 having a pentode V2 or a resistance (not shown) as cathode load. As the voltage at the cathode of V1 rises, the current in deflection coil W1 decreases whilst that in W2 increases. The sweep is terminated by trigger pulses F firing a gas tube V3 to discharge capacitor C. A fixed potential may be provided at the lower end of capacitor C so that the direct current components in each coil W1, W2 are the same. Alternatively the potential at the lower end of capacitor C is adjustable by R3 to provide trace centering. The potential at the grid of V1 is limited by a diode Dl in the event of failure of trigger pulses, F the cathode potential of Dl being sufficient to ensure the spot is off the screen. Modifications. The coupling potential El may be derived from the H.T. supply or may be replaced by a capacitor. The linear sweep generator may be replaced by a bootstrap staircase waveform generator, each step being triggered by a line pulse. V1 may be replaced by a pentode or an emitter follower transistor.

[Class 38 (iii)] Non-regenerative braking.- A control system for an asynchronous motor effecting traversing and like movements of a crane, comprises a controller having forward and reverse positions on opposite sides of an " off position, and a mechanical brake operated by an alternating current motor, the brake being raised to an extent corresponding to the slip frequency of the driving motor at the first driving positions of the controller, and fully raised at the subsequent driving positions, and an auxiliary switch also being provided by the operation of which the main motor is disconnected at the subsequent driving positions, and subjected to reverse-current braking at the first driving positions. At the first positions of a controller C, a switch CS connects a brake operating motor E to the secondary of the main driving motor M. At the higher speed positions of the controller C the switch CS is operated to connect the motor E to the supply and so completely raise the brake. Upon operation of an auxiliary switch D, the main motor is disconnected if the controller C is in its higher speed positions, but if the controller C is at its first driving position, the reversing contactors A, B, are operated to reverse the connections of the main motor, the motor E, connected to the secondary of the main motor, completely raising the brake. The brake is operated by the motor E through electrohydraulic apparatus such as described in Specification 363,137, [Group XXXIV].

Abstract: 239,031. Isaac, A. L. Aug. 11, 1924. Rotary distributors of the type having a rotary eccentric contact ring b, b<1> pressed radially by a spring c against an internal contact raceway, the spring c being interposed between the contact ring b and a bush secured to the distributor shaft, have the bush a formed on the side a<1> remote from the spring with the same curvature as the contact ring b so that when the distributor is in position thereby freeing the bush from the internal periphery of the contact ring, rocking movement of the contact ring with respect to the bush is reduced to a minimum. The bush is provided at one side with a flange a<6> which with a washer e at the other side retains the ring in the axial position. One end of the spring c is housed in a recess a<5> in the bush and the other end bears against a curved metal plate d bearing on the contact to increase the, friction at that point. Where the eccentric portion a<1> of the bush joins the concentric portion a<2> horns a<3>, a<4> are formed which may be replaced by pins standing out from the bush. A blade spring may be used instead of the coiled spring c.

Density separators.-In a centrifugal separator with a liner two independent feeding passages extend down the central part; one terminates near the periphery of the bowl and supplies the denser liquid, the other terminates between the centre and periphery of the bowl near orifices in the liner. The driving shaft d, fits in a socket in the bottom of the bowl a. Fonr channels i communicate with the central feeding passage h and extend to the edge of the disc j at the bottom of the liner. A tube k passes outside the tube h and passages l arranged alternately with the passages i discharge the liquid from the tube k opposite holes x in the liner plates y. A top disc n with a neck p is arranged above the liner and the space above the disc n communicates with the outlet f for the heavy liquid, while the light liquid is discharged from the inside of the neck p. Covers q catch the materials discharged from the bowl. When in operation, water, brine, or some other liquid heavier than that to be purified is supplied through the tube r and flows through the channels h, i to the bowl periphery. The lighter liquid is supplied through the tube s and passes to the holes in the liner plates and then upwards to the discharge neck p. Any solids in this liquid are thrown out and are carried upwards by the heavier liquid to be discharged through the opening f. Wings v, w are provided to carry the liquids round with the bowl. Specification 142,860 is referred to.

Abstract: 1302942 Starch adhesives OGILVIE FLOUR MILLS CO Ltd 22 April 1970 [25 April 1969] 19257/70 Heading C3U An adhesive composition, particularly suitable for use in the manufacture of laminated and corrugated paperboard, is made by preparing an aqueous caustic solution, e.g. from sodium hydroxide flakes, rapidly adding granular starch (corn, wheat or tapioca) to the solution, raising the temperature of the resulting slurry, whereupon the starch granules swell thickening the slurry, permitting the swelling to continue until a Zahn #3 viscosity (defined) of 12 to 60 seconds is attained, and abruptly terminating the swelling and concomitant thickening by adding a reaction stopper to the slurry. Typically, the temperature of the slurry is slowly raised by steam injection until it is within the range 102-110 F. and the slurry is held at a temperature within this range until a Zahn #3 viscosity of 20-30 seconds is attained. Reaction stoppers: alum, aluminium sulphate, borax, hydrochloric acid, magnesium sulphate, sodium acid phosphate, sodium bicarbonate, sodium bisulphate, sulphamic acid and water. The adhesive compositions may include between 2 and 15%, based on the initial starch weight, of a phenol-formaldehyde, melamine-formaldehyde, urea-formaldehyde or acetone-formaldehyde resin.

IPC: G05G15/08
Filed: 1955-07-04
Abstract: 782,682. Dynamometers. DURAND, F. July 4, 1955, No. 19262/55. Class 106 (2). [Also in Groups XXIV and XXXVII] Relates to an arrangement in which an electric motor 9 drives an output shaft through a universal joint 40 and a worm shaft 12, the worm-wheel being journalled directly in the reduction-gear casing 1 by having its hub mounted on the end portion of the output shaft. A reaction arm, rigid with the casing 1, has its free end coupled to a torque-responsive device comprising a cylinder 41 surrounding a stack of dished washers and a piston 42, the reaction arm being pivoted on a pin 43. Another pin 44 carries a rod 45, which is attached to a fixed part of the plant, and a rack 46 co-operating with a control box 47. In another arrangement, the control box is mounted independently of the cylinder, Fig. 6 (not shown). Any displacement of the casing 47 relative to the rack 46 rotates disc 53 until pin 55, for example, engages cam 60, which is carried on a lever, to depress pushmember 61. Thus a desired operation may be effected, such as de-energizing the driving motor, actuating signalling means, or starting another motor. On the cover 63 a graduated dial 64 may be provided and a pointer 65 to indicate the value of the torque. The pointer 65 is carried by shaft 66 which is rigid with the disc 53.
