Title: Composite resinous products
IPC: B32B27/00
Filed: 1940-01-30
Abstract: 540,940. Synthetic resins. PITTSBURGH PLATE GLASS CO. Jan. 30, 1940, Nos. 1869 and 1870. Convention dates, Feb. 18, 1939 and Nov. 2, 1939. [Class 2 (iii)] An artificial glass comprises a transparent flexible plastic base with a harder surface film of a wear-resistant polymer of an organic compound containing at least two defined polymerizable unsaturated groups, such as are described in Specifications 536,807, 540,938 and 540,939. The flexible base may consist of similar polymeric material polymerized in the presence of plasticizers or co-polymerized with other materials, e.g. vinyl capable of forming only linear polymers ; materials prepared from phenol or urea condensation products or alkyd resins, or casein or cellulose plastics. In one form, the plastic base is coated with a solution of a fusible polymer, described in the earlier Specifications, and, after evaporation of the solvent, the surface film is converted to the infusible state. As a modification a single polymer varying in degree of polymerization from the interior to the exterior may be employed, e.g. by subjecting a partially polymerized sheet to surface heating, by incorporating a greater catalyst concentration adjacent the surface, by the use of inhibitors in the interior portion or by utilizing different concentrations of plasticizer in the interior and exterior portions. Examples are given involving the following bases and fusible polymer coatings-polymethyl methacrylate coated with poly- (1) allyl methacrylate ; (2).allyl chloroacrylate ; (3) diallyl oxalate ; (6) allyl crotonate ; (8) diallyl phthalate and (9) allyl ethyl maleate ; base copolymers coated with fusible polymers viz. methyl methacrylate/allyl crotonate with ethylene glycol dicrotonate ; (5) methyl methacrylate/allyl methacrylate with glycol dimethacrylate; (10) vinyl acetate/diallyl succinate with allyl methacrylate, and (11) methyl methacrylate with diallyl maleate, and (7) cellulose acetate coated with a fusible polymer of allyl methacrylate with the aid of an intermediate, adhesive layer of nitrocellulose.

Filed: 1929-01-19
Abstract: 326,924. Butler, E. W., and Mann, J. C. Jan. 19, 1929. Cauldrons.-A method of mixing liquids initially at different temperatures, such as hot pitch and tar, the temperature of which during the mixing process has to be maintained within prescribed limits, consists in continuously passing one liquid through a series of mixing vessels and adding thereto in the various compartments one or more other liquids with or without further quantities of the first liquid to maintain the appropriate temperature in each compartment.

Abstract: 400,465. Changing signs. YOUNG, C. D., Church Road, Soundwell, Steeple Hill, near Bristol. Jan. 20, 1933, No. 1930. [Class 3 (i).] A device for displaying articles, which brings different compartments in succession to a display aperture 42, comprises a table e to which continuous rotation is imparted by a friction wheel k driven by an adjustable-speed motor i and spring-pressed against the table rim h. The compartments are formed by mirrors 15 disposed radially on a disc 10 to which intermittent motion is imparted by the table e. The operating mechanism consists of a cam r which forces an abutting member z on a spring-biassed pivoted arm l mounted on the table e into the path of a ring of pins 20, one for each compartment, depending from the disc 10. The disc 10 is thus moved through 90‹ for each revolution of the table e. A screen 30 extending through 180‹ is fixed to the table e, and conceals the exposed compartment just before the latter partakes of the motion of the table e. The compartment frame is registered in position by a spring-pressed ball 27 snapping into holes in a leather-covered disc 25. A lamp 43 may be switched on to illuminate the compartments only during display. The whole device may be designed to represent a lighthouse.

The wheel 84 is divided by spaced discs 103 and radially disposed ribs 104 into compartments 105. The amount of raw material falling into the compartments 105 is regulated across the wheel by a series of valve members 107 each having a sloping upper surface 111, bent down at the edge 112, and mounted on a threaded rod 120 parallel with wall 92 so that the distance S between the edge 112 and rear wall 93 can be varied, the central member 107 having the greatest distance S and the outermost members the least. A closure plate 108, which may be used to compact or adjust the raw materials in the compartments 105, is mounted for movement towards and away from the wheel 84 on a threaded rod 125 and for pivotal movement relative thereto on a threaded rod 126, the rods 120, 125 and 126 being mounted on wall 92 by brackets. In one modification the vane wheel is in two parts, joined centrally by a universal joint, and which may be adjusted to lie at an angle to each other so that the central thicker part t of the layer J is deposited ahead of the thinner edges f. In a further modification, the thickness of the layer J may be varied additionally by a vane wheel larger at the centre so that the compartments are progressively smaller towards the ends of the wheel.

Title: Improvements relating to control systems for direct current motors
Inventor: BENNETT JAMES HOLMES
IPC: H02P5/68
Filed: 1952-02-01
Abstract: 715,148. Control of several D.C. motors. ENGLISH ELECTRIC CO., Ltd. Jan. 30, 1953 [Feb. 1, 1952], No. 2753/52. Class 38(3) A main mill motor 10 drives main rolls 11  through which a billet 12 is fed in opposite directions on each succeeding pass. A tachometer generator 13 is driven by the motor 10 and supplies the field windings 16a, 17a, of auxiliary Ward Leonard generators 16, 17. Live rolls 18, 19, on opposite sides of the mill are driven by motors supplied from the generators 16, 17, respectively. In order to increase the excitation of the auxiliary generators when the voltage of the tachometer generator is low at starting, a fixed voltage is derived from transformer 21 and rectifier 20 the output of which is kept in the same sense as that of the tachometer generator by means of change-over switches 14, 15, coupled to the main mill reverser. The torque of the motors driving the live rolls 18, 19, is thus automatically boosted at starting, and, when the mill speed increases, the control of the auxiliary motors is taken over by the tachometer generator which maintains the speed of the live rolls in a fixed relationship with the speed of the mill. In an alternative arrangement, the output side of the rectifier 20 is connected in parallel with the tachometer generator, and blocking rectifiers prevent reverse current flow through the rectifier when the voltage of the tachometer generator exceeds that of the rectifier. Specification 715,149 is referred to.
