Title: Method for the production of permanent magnets
IPC: C08L63/00
Filed: 1962-05-07
Abstract: 999,389. Magnetic compositions and structures. LANDES & GYR A.G. May 7, 1962 [May 15, 1961], No. 17415]62. Heading H1H. A permanent magnet structure is formed by incorporating magnetic particles into a mixture of epoxy resin and phenolic resin, moulding to shape at room temperature, removing from the mould and heating to cure the resin. The magnetic particles may be alnico or a ferrite comprising oxides of Fe, Ba, Sr and Pb. The epoxy resin component may be a reaction product of a polyhydric phenol and an epichlorhydrin, and glycidyl esters may replace glycidyl ethers. Proprietary resins of this type are " Epon and " Epotuf " (Registered Trade Marks). Alternatively the epoxy resin may be a reaction product of epichlorhydrin with a permanently fusible phenol formaldehyde or novolac resin, and two methods of production are specified. A proprietary glycidyl ether of a phenol formaldehyde novolac resin is Den. A further specified glycidyl epoxy resin is a glycidyl ether glycidyl ester complex prepared from diphenolic acid by reaction with epichlorhydrin. The phenolic resin component may be the permanently fusible novolac resin used in the preparation of the second type of epoxy resin above. Among those specified are a condensate of p-tertiary butyl-phenol and formaldehyde (Super Backacite), a condensate of formaldehyde with octyl phenol in which the cetyl group is a highly branched chain (Amberol), and a novolac resin (Foundrez). The two resin components whose weight ratio may lie between 15: 85 and 85: 15 are mixed with a tertiary amine catalyst and the magnetic particles by one of several methods including the method of dissolving each resin separately in methyl ethyl ketone, adding the particles, mixing and evaporating the solvent. The material is ground providing coating magnetic particles ready for moulding. The catalyst may be triethanolamine or the proprietary materials " Quadrol " and " Ethomeen " (Registered Trade Marks). In examples the following mixtures are specified:-Epotuf - Foundrez-triethanolamine, Den - Foundrez - triethanolamine, Den - Super Backacite - triethanolamine, Den - Amberol- Epotuf - triethanolamine, Foundrez - Epotuf- Quadrol, Den-Foundrez-Quadrol. In manufacturing the magnetic body the coated magnetic particles are placed in a lubricated die, compressed under 40,000 p.s.i., removed, and cured for at least 30 minutes at 300‹ F. Polyethylene glycol and lithium stearate may be added to the powder. The bodies are magnetized. Specification 998,853 is referred to.

Title: A machine for boring and/or filling brush heads
IPC: A46D3/06
Filed: 1959-05-26
Abstract: 920,258. Brush-making. W. EBSER. May 26, 1959 [May 27, 1958], No. 17836/59. Class 83 (3). [Also in Group XXIII] An automatic machine for brush-making comprises apparatus for adjusting with constant or alternating width of step in the same or reverse direction at least one movable element and including a slidable pin 35, the axial position of which determines the width of step, the position of the pin being determined by at least one of a number of slidable elements 38 moved between the base of the pin and a fixed stop, said elements being removed after the step has been carried out. The machine is for drilling and filling brush-stocks by axial movement of a drill and means for inserting bristles. The depth of hole is determined by a rod 1 moving a slotted member 5 engaged by a pin 8 on a bracket 6. The vertical displacement of the brush-stock is determined by a rod 2 which moves a bell-crank 10 by way of a link 9, the crank 10 carrying a roller engaging the brush-stock carrier 7. Lateral displacement of the stock is determined by a rod 3 connected by a link II to the stock carrier 7 to pivot it on the bracket 6. Each control rod is associated with a pin, the pins and rods being clamped between adjustments by hydraulic pistons 16, 48, 49 controlled by cams 51, 52, on a shaft 25, and valves 55, 56. Each pin 35 can be raised by a cam 26, a lever 28, a link 29, a pivoted guide 18 and a link 34. The pivoted guide carries a rod 19 connected by links 17, 21, 23 to a control rod. When the cam 26 moves the lever 28, the pin 35 is raised to allow one or more of the laminations 38 to be inserted beneath the pin before it is pressed downwardly again by a lever 37. The laminations are selected by a punched band 41 which is advanced towards the laminations, the ends of which carry pins which, if unselected, may pass through holes in the band, the selected laminations being pushed forwardly. A spring-pressed lever 73 is connected to each lever 37 and is controlled by an eccentric 74 on the shaft 25 to assist in compensating for differences in the set positions of the associated pin 35. A gear 104 on the shaft 25 drives a disc 105 carrying a pin 106 to rotate a toothed wheel 107 and advance the band after each operation. The band is moved to and from the elements by an eccentric 91 and a lever mechanism. The cams on the shaft 25 control the whole machine so that while one stock is drilled, another is tufted. Each clamping device, such as 49, Fig. 11, comprises an hydraulic piston 49 supported by a spring return disc 65.

Title: Microprogrammed data processing systems
IPC: G06F13/26
Filed: 1973-04-13
Abstract: 1448866 Microprogram interrupt INTERNATIONAL COMPUTERS Ltd 13 April 1973 17864/73 Heading G4A Different micro program interrupt levels have respective micro program address registers and working registers allocated thereto, the lowest interrupt level being associated with operations carried out by the processor and the other levels being associated with peripheral devices. A peripheral control system 31 selects the highest priority service request 41 from peripheral device couplers. Where two or more devices share the same interrupt level a priority selection among those devices may also be made. The selected priority level (1-7) is set in a register 57 to address a 16-word random access memory 65 containing the address registers for 16 levels of interrupt, the start address supplied over path 49 by the selected peripheral being loaded into the address register in memory 65. The highest interrupt level (0) is for fault handling and the lowest levels (8-15) are associated with operations which only involve the processor and are selected sequentially by a reversible counter 55 in the absence of a higher level interrupt (0-7). Other random access memories addressed by register 57 contain the working register for each interrupt level. There may be a single pair of operand working registers common to all the processor interrupt levels (8-15). Interrupts are initiated by a comparator 59 which compares the current interrupt level in register 57 with the highest priority interrupt request level. A jump from one processor routine to another is effected by a LINK micro instruction which steps counter 55 to the next higher priority level and loads the appropriate micro program address register with the start address specified by the instruction. On return, an EXIT micro instruction steps counter 55 back to the original level. Micro instruction fetch, decode and execution are pipe-lined, and when a return from an interrupt takes place, it may be necessary to return to a micro instruction which had already been read from a control store, this function being performed by a random access register bank 74 and logic 72 which keeps track of the number of micro instructions to be nullified by subtraction in AU 78 from the current address in the selected address register of bank 65. Micro instructions are described for combining bytes from different sources to perform a word, converting, by shifting, between 24-bit word format and 4-byte, zero-filled 32-bit word format, over-writing a selected bit in a selected word by a literal value of one or a specified flag, or replacing a specified flag by a nominated bit, e.g. for testing peripheral status, and for jump on testing a nominated bit of a specified operand.

Filed: 1931-04-09
Abstract: 384,678. Fluid - pressure brakes. VAGO, P. VON, 51, Budafoki-ut, Budapest, and UHER ENGINEERING CO., Ltd., Glarus, Switzerland. April 9, 1931, No. 17866/32. Divided on 376,808. [Class 103 (i).] In a brake having liquid transmission the piston 122 producing the braking pressure is constructed as the piston of a servomotor, the supply of liquid under pressure to which is controlled by a distributer piston 138 connected to the brake pedal. Pistons 122, 138 engage one another by means of a spring 151. The actuating liquid is stored in a reservoir having an air cushion by a pump driven by the vehicle motor or by the vehicle shock absorbers con. structed as pumps and this reservoir is connected to a recess 134 in the servomotor cylinder. Movement of the distributer piston 138 by the pedal controlled lever 147 to the left opens the recess 134 by ports 137, 139 to the space 125 behind the brake piston 122 which is forced to the left to apply the brakes by means of the hydraulic cylinder 145, the pressure in which reacts in the chamber 144 on the pedal operated piston 138. When the pedal is released the piston 138 is moved back by the pressure in the cylinder 145 to connect the ports 126, 162, 140 to release the pressure from the space 125 to the reservoir 119. If the pressure fails the piston 122 is moved by foot pressure by means of the piston 138 and an abutment 141, a shoulder 142 of which engages a shoulder 143 of the piston 122. Leakage losses in the hydraulic transmission are made good through a bore 133 in the cylinder 145 in release position. An excess pressure release valve 136 is provided for the chamber 134.
