Abstract: 1502813 Artificial teeth O W ROGERS 23 April 1975 [29 April 1974 31 Dec 1974] 16762/75 Heading B5A A method of forming tooth crowns or inlays, comprises forming a tooth model which may be coated with metallizing paint, electrolytically depositing a metal on to the model to form a matrix, building up porcelain on the matrix, and, optionally, removing the metal matrix from the porcelain with aqua regia. Suitable metals include gold, platinum, palladium or rhodium, or an alloy of these with platinum, palladium, rhodium, silver, copper, nickel, cobalt or indium. Alternatively, the matrix is formed of gold or gold alloy and coated electrolytically or by a vacuum technique with one of iron, tin, zinc, copper, nickel, chromium, cobalt, vanadium, platinum and palladium, and the surface of the metal is then treated with a mineral acid. The matrix may be burnished around the base of the tooth after fitting and a vent tube may be formed in the matrix to release pneumatic pressure, the tube being sealed with a gold plug or a self-tapping screw. Composite gold and porcelain crowns may be formed and a chelating cement, e.g. zinc phosphate, zinc oxide eugenol or polyacrylic acid, cements, used with a conventional cement to bond the crown to the tooth. The model tooth is protected from chemical attack during electrolysis, e.g. if the electrolyte is platinic chloride, by an epoxy resin composition, e.g. epichlorohydrin bisphenol.

Title: Improvements in instruments for measuring properties of rubber and rubber-like materials
IPC: G01N11/14
Filed: 1944-09-05
Abstract: 578,496. Testing physical qualities. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., and MAcDONALD, H. A. Sept. 5, 1944, No. 16917. [Class 106 (ii)] In a rotary cylinder plastometer for measuring the properties of rubber-like materials, the chamber, which houses the driven rotary member and is adapted to be filled with the material to be tested under pressure, is mounted to be rotatable about its axis, but is locked, when it is desired to measure the shearing viscosity, by means which can be released when the rotor is stopped so that the chamber rotates under the forces of recovery to an extent that can be observed with the aid of an indicating device associated with the chamber. In its simplest form (Fig. 1) the apparatus comprises a chamber 1 and rotor 2, between which the material under test is contained under pressure, and an electric motor 6 which drives the rotor through a high ratio worm and worm-wheel gear 8. For shearing viscosity measurements, the chamber is locked by a pin 9 and the torque, which is a measure of the shearing viscosity, is obtained by measuring the endwise thrust on the worm-wheel shaft. By means of relays (not shown) the motor is then switched off and simultaneously a brake 12, 13 is operated electromagnetically. A retarded relay then operates a solenoid which withdraws the pin 9, allowing the chamber to rotate on ball bearings 3 under the forces of recovery of the material, the rotor being locked by the worm gear. A scale on the chamber co - operates with a stationary pointer 11 to indicate the extent of the rotation. Owing to the large inertia of the armature of the motor, it is advantageous to insert a clutch so that the armature may be disconnected from the rotor. The clutch may be inserted between the motor and the reduction gear or between the latter and the rotor as shown in Fig. 3. In this case, when the motor is switched off, a solenoid 26 is also deenergized so that, under the action of a spring 31, a lever 25 disengages the clutch and brings a friction plate 32 on the shaft of the rotor into contact with a similar but stationary plate. The rotor is thus stopped and then further movement of the lever 25, allowed by compression of the spring 35, withdraws the pin 9. To repeat the procedure, the motor and the solenoid 26 are re-energized, whereupon the latter re-engages the clutch and, when the chamber has rotated sufficiently, the pin 9 is pressed into its recess in the chamber under the action of a spring 36.

Abstract: 615,526. Extruding-machines. COMPAGNIE GENERALE D'ELECTRICITE. July 3, 1945. No. 16954. Convention date, May 11, 1940. [Class 87 (ii)] The width of a strip 5 of rubber or other material which is fed to an extrusion screw 3 by a conveyer 6 is regulated, in order to control the amount of material fed to the screw. The material 10 is flattened between two rollers 8, 9 and the strip is cut therefrom by circular cutters 11 which are pivoted at 12 and pressed against the roller 9 by a weight 13. The cutters are mounted on a shaft 18, one on each of two counter-acting screw threads. The operator alters the spacing of the cutters by operating a motor 21 to turn the shaft 18. The width of the strip is much less than the width of the cylinder feed orifice 4, and the strip, if fed quickly, collects in zig-zag fashion on an inclined plane leading to the screw. The machine is used to coat electric wires and cables.

Title: Improvements in or relating to automatic control devices for change speed gear boxes
IPC: F16H61/00
Filed: 1945-07-05
Abstract: 598,605. Controlling change-speed gears. LAVALLEE, P. July 5, 1945, Nos. 17136 and 17137. Convention dates, Oct. 30, 1942, and Sept. 20, 1943. [Class 80 (ii)] [Also in Group XXXVIII] An automatic control device for electromagnetic change-speed gears, particularly for use on vehicles and machine tools, is responsive to the speed of the output shaft of the gearbox and operated by an electric generator driven thereby. As shown, an engine 1 drives a vehicle through an electromagnetic gearbox 2, the four forward speeds of which are controlled by relays 13, 15, 16 and 17. The first speed relay 13 is energised by the closing of a switch 12 by the initial movement of the acceleratorpedal 11 whilst the other relays are controlled by voltage sensitive relays 5, 6 and 7 respectively. These latter relays are energised by the rectified voltage from an A.C. generator 3 driven from the output shaft of the gearbox 2 and a rectifier 4, so that they are actuated successively in accordance with the speed of said shaft. Energisation of relay 5 closes the coil circuit of relay 15 to close contacts b to bring in the second speed and at the same time open contacts a to break the coil circuit of relay 13 to disengage first speed. Similarly when relay 6 energises relay 16 the latter brings in third speed and breaks the circuit of the second speed relay 15 and so on. On fall of speed of the output shaft of the gearbox the speed ratios are changed successively downwards. Reverse speed is obtained by the operation of a switch 18 which is locked by a device 19 when any of the relays 15, 16, or 17 are in operation. The speed control may be modified by some other factor such as the position of the vehicle accelerator-pedal, the vehicle load, the nature of the ground or the volition of the driver. This may be conveniently carried out by means of resistances 8, 9 and 10 in the circuits of the relays 5, 6 and 7 and operated, for example, by the accelerator-pedal 11. In an application to a machine tool, such as a lathe, the speed control is modified by the position of the cutting tool to maintain the optimum cutting speed for the work by varying the action of a potentiometer, in parallel with the rectifier 4, on a speed limiting relay which is initially set to the desired optimum speed required. In an arrangement in which the driving motor 1 is a multi-speed electric motor further relays may be provided to extend the speed range by controlling the motor speeds as well as the gearbox.
