IPC: H01H50/16
Filed: 1926-03-03
Abstract: 272,574. General Electric Co., Ltd., and Angold, A. E. March 3, 1926. E l e c t r o magnetic switches. - A relav comprises a pivotally mounted magnet having a pole biassed towards a point at or near the centre of the length of a relatively long solenoid and adapted to move parallel to the axis of the solenoid. Within definite limits of movement, the force acting on the magnet is substantially proportional to the value of the current in the solenoid since the poles of the solenoid have no effect on the magnet. As shown a pivotally mounted bar magnet 4 co-operates with the solenoids 2, 3 wound in series on an iron ring 1 to produce when current flows torques which act on the magnet in the same direction and consequent poles at the unwound portions of the ring 1. Separate solenoids may be employed to produce a differential torque or movement of the magnet in one or other direction. Instead of a single bar magnet a group of magnets or an electromagnet may be employed. The solenoids mav be arranged on arcs of different radii. The Provisional Specification states that the consequent poles may be utilized for producing an adequate closing force for the contacts of the relay.

Title: Improvements in the production of esters of tertiary alcohols with unsaturated acids
IPC: C07C69/54
Filed: 1958-02-26
Abstract: Esters of tertiary alcohols with unsaturated acids are produced by adding an olefinically unsaturated compound having a tertiary carbon atom in the olefinic group and a chain length up to 12 carbon atoms at a temperature between 10 DEG  and 25 DEG  C. to a solution of acrylic acid, methacrylic acid or a -halogen-substituted acrylic acid, in an indifferent organic solvent in the presence of an acid-reacting catalyst.  Examples of olefinic compounds are isobutylene and isoamylene.  Suitable indifferent solvents are cyclohexane, gas oil, and synthetic oils such as a polyisobutylene with a molecular weight of about 1000.  The reaction is preferably effected at room temperature and in some cases it is advantageous to use a slightly increased pressure of 1 to 5 atmospheres.  The preferred catalyst is 85 to 100 per cent sulphuric acid in amounts of 4 to 10 per cent with reference to the unsaturated acid.  Other suitable catalysts are boron trifluoride and its complex compounds and other Friedel Crafts catalysts.  Polymerization inhibitors such as hydroquinone and thiodiphenylamine may be added in amounts of about 0.05 to 1 per cent based on the unsaturated acid.  In examples, (1) acrylic acid dissolved in cyclohexane is reacted with isobutylene in the presence of sulphuric acid at room temperature and normal pressure to yield tertiary butyl acrylate; (2) acrylic acid is mixed with low molecular weight polyisobutylene and reacted with isobutylene in the presence of sulphuric acid to yield tertiary butyl acrylate; (3) methacrylic acid dissolved in cyclohexane is reacted with isobutylene in the presence of sulphuric acid to yield tertiary butyl methacrylate.

Abstract: 1528361 Indexing flash-cube sockets KODAK Ltd 13 Feb 1976 [13 Feb 1975] 6175/75 Heading G2A A flash-cube socket is indexed by a sliding member tensioned when the film transport means is operated, so that the socket is indexed when the film transport means returns to its rest position. As shown, the film transport is operated by a slider 1, moving in direction A against a spring 7. A drive arm 2, pivoted at 2c, has a pin 2a at one end engaging in a slot 1a in slider 1. A further sliding member 3, biased by a spring 8, has faces 3a, 3b which engage with pins 6b, 6a respectively on the flashcube socket 6. When slider 1 is moved in direction A, drive arm 2 pivots clockwise. An extension 2b of arm 2 engages a lug 3d of member 3, sliding it to the right and so tensioning spring 8. Also, face 3b, sliding against pin 6a, causes member 3 to move away from the socket. When slider 1 is released, and is returned to its rest position by spring 7, spring 8 draws member 3 to the left again, so that face 3a of member 3 engages pin 6a, and so rotates the socket. When no flash-cube is in the socket, a door 4 may be closed, which disengages member 3 from drive arm 2, so that movement of slider 1 does not rotate the socket.

Title: Improvements in or relating to drawing buffers for presses
IPC: B21D24/08
Filed: 1953-03-09
Abstract: 725,966. Cupping. SCHULER AKT.-GES., L. March 9, 1953 [April 2, 1952], No. 6459/53. Class 83 (4). An hydraulically cushioned drawing buffer for a cupping press is characterized in that the buffer cylinder which is guided on a stationary piston is operated pneumatically or hydraulically and encloses all other elements of the drawing buffer. The buffer cylinder 1 is guided externally in a cylinder 3 formed on the machine frame 2 and internally by a stationary piston 4. Pins 6 connected with the drawing tool (not shown) rest on the end 5 of the buffer cylinder. The piston 4 has an annular shoulder 7 and the lower end of the buffer cylinder is restricted by a threaded ring 8, a packing sleeve 10 and a retaining ring 9 so that a fluid-tight chamber 11 is formed between the buffer cylinder and the piston 4. A channel 12 connects the chamber 11 with a non-return inlet valve 13 which controls the flow of pressure fluid 14 from a chamber 15 formed within the buffer cylinder. The chamber 15 also contains compressed gas supplied through a pipe 16. A return flow release valve 17 also communicates with the chamber 11, said valve being operated by an hydraulically or pneumatically actuated piston 18. The valve 17 controls the fluid return flow through a channel 23 into which is built a throttle 25 adjustable by a tapered shank 24 and an outflow non-return valve 26. In operation when the buffer cylinder is depressed by the pins 6 the chamber 11 enlarges and pressure fluid is drawn from the chamber 15 through the inlet valve 13. When the press ram moves upwards after the drawing operation the return of the buffer cylinder is delayed by the valve 17 to prevent damage to the drawn article. After the ram has moved a predetermined distance the valve 17 is opened by supplying fluid pressure to the chamber 21 and releasing the pressure from chamber 19 of the valve thus the pressure fluid in the chamber 11 meters back to the chamber 15 and the buffer cylinder returns to its initial position. The delaying effect of the valve 17 can be overcome by removing pressure fluid from both sides of the piston 18 in which case a spring 27 or the weight of the piston holds the valve 17 open so that the buffer cylinder moves upwards immediately after reaching its lowest position.
