Patent GB-1598837-A (GB)
Title: Temperature resistant abrasive compact and method for making same
IPC: C22C29/16
Filed: 1978-02-16
Abstract: A tool component, in particular a cutting insert, essentially consists of self-bonded abrasive particles and a network of mutually communicating, dispersely distributed pores. This tool component is made by directly bonding a mass of abrasive particles to one another to give a self-bonded object, using a sinter aid material at high pressures and temperatures. The object formed under the action of the high pressures and temperatures contains self-bonded particles, i.e. particles directly bonded to one another, and is penetrated by the sinter aid material, for example cobalt or cobalt alloys. The sinter aid material is then removed, for example by immersing the object into aqua regia. It has been found that, by removal of essentially all the sinter aid material, an abrasive particle object is obtained which shows a substantially improved resistance to thermal decomposition at high temperatures.

The cord should be at least twice the diameter of the insulated wire of which the coil is wound. The coil is wound on a frame a of vulcanite or other insulator. A zig-zag layer of cord may be wound on the mandrel of the winding machine before the former is placed in position, this layer being afterwards gathered up with the others. The coil and its former are secured to an insulating block g by a metal strap l and screws n. Alternatively the former may be secured directly to the block by screws passing clear of the windings. The ends of the coil are secured to a plug and socket on the block by screws k. The coil may be secured to the block by a flexible insulating strap around its periphery the ends of which are joined by a butt or scarf joint. The strap may be of sufficient length to accommodate the largest size of coil required being cut as required for smaller coils. The strap may be screwed to the block or moulded in one piece with it. Stiffening strips may be provided outside or inside the coil and secured bv the lacing member; or two laces may be provded drawing some of the loops over an outside strip and the remainder over an inside strip.

Abstract: 1,070,133. Stretching filaments. CHEMCELL (1963) Ltd. Jan. 20, 1965 [April 15, 1964; April 24, 1964], No. 2571/65. Heading B5B. [Also in Division H5] In a machine for stretching a plurality of single and multi-filament thermoplastic yarns each yarn from a bobbin (15), (Fig. 5, drawings not shown) passes over a draw off device comprising (4) nip rolls, past a drop wire arrangement (K) detecting breakages, about a snubbing device (25), through a curved electric heating element (R) to " skewed advancing " stretch rolls (29), (30). The element (R), (Division H5) comprises a smooth channel of increasing width having a temperature gradient with the inlet end hottest. The wall temperature is measured by a thermocouple (V) and compressed air can be blown through the element to thread a yarn or to cool the element if the yarn breaks. The drop wire arrangement (K), Figs. 14, 15, comprises a wire (101) normally resting on the yarn (Y) and pivotally connected to a piston (95) having a narrow part (97). The piston slides in a bore (87) in a body (80) and is connected to a compressed air manifold (26a). If the yarn breaks the wire (101) falls and moves the piston allowing air to pass to the element R, a slotted arrangement allows the wire to gather momentum before engaging the piston. To thread yarn through the element a manual valve 111 connected to a manifold 110 is operated.

Title: Data conversion system
IPC: G06F5/00
Filed: 1966-01-20
Abstract: 1,067,981. Data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 20, 1966 [Feb. 1, 1965], No. 2599/66. Heading G4C. Access control means for an addressable matrix store can operate in either of two modes, one in which the memory positions are accessed successively on a row by row basis and one in which they are accessed successively on a column by column basis, there being means responsive to completion of a cycle in which all the positions are accessed to change the mode. Referring to Fig. 1 (not shown), an NxN magnetic core plane (10) is addressed by N- position row and column ring counters (56, 54) driven by clock pulses via logic partly controlled by a flip-flop (98), so that the cores are accessed individually row-by-row or column-by-column depending on the state of the flip-flop (98). As each core is accessed, its bit is passed to one of N remote terminals by a distributer (58) driven by the clock pulses, and a new bit is written in. The new bit comes from an N-bit shift register (28) shifted by the clock pulses and periodically refilled by an N-bit parallel byte from a computer memory, e.g. magnetic tape (42). When all the cores have been accessed, circuits (70, 74) detecting the final states of the counters (54, 56) switch the flip-flop (98). Thus the core plane (10) is completely accessed rowby-row and column-by-column alternately. The above system may be modified so that data passes through it in the opposite direction (Fig. 3, not shown). If the number of bits per message byte is unequal to the number of remote terminals, several of the above systems can be provided, but with the addressing circuitry in common (Fig. 4, not shown), or dummy bits can be used. In the computer memory queues of data for different terminals could be provided, each with its own address register. Multi-bit bytes could be sent to or received from the remote terminals by using a 3D memory in place of the plane (10). A non-square core plane is mentioned.
