Filed: 1965-09-29
Abstract: 1,086,469. Continuous casting machines. CONCAST A.G. Sept. 29, 1965 [Sept. 29, 1964], No. 41429/65. Heading B3F. In a continuous casting machine guiding means is provided, between the mould and the withdrawal rolls which comprises frames 10, Figs. 1 to 4, carrying shafts 15 and 16 on which are mounted guide rollers 17 and 18 respectively, and shafts 19 and 20, mounted perpendicularly to shafts 15 and 16 and which carry rollers 21, 22. The rollers are arranged in pairs, one on each side of the strand to effect supporting and guiding thereof. Coupling straps 23, and 24 are provided between each successive frame 10 and are carried on the shafts 15 so that a swivelling action between the frames can be achieved in order that the guiding action can be effected around a curved path following the curvature of the strand in a curved casting process. Guiding of the frames 10 around a predetermined curved path is effected by rollers 30 on extensions of the shaft 15, the rollers 30 co-operating with a groove in the side supports 35 of the machine. The swivelling movement of the frames is limited by the abutment faces 25 between respective frames. In a vertical casting process the frames may not be hinged together but merely stacked one on top of the other within a frame on the machine and are transversely located by means of the rollers 30 or by dowels interfitting between each frame. Adjustment of the rollers transversely to the axis of the strand to compensate for variation in the thickness of the strand is effected by eccentric bushes in which shafts 16, 19 and 20 are mounted. Known type spray cooling means is attached to the guiding means.

Abstract: 984,886. Lubricating guns. CASTROL Ltd. Dec. 31, 1963 [Nov. 2, 1962], No. 41626/62. Heading F2A. A lubricating gun has a nozzle with two parts so arranged that on applying the nozzle to a nipple, there is relative movement between the two parts which opens a valve to permit the flow of lubricant through the nozzle, and on release of the nozzle the valve is automatically closed. According to the invention the gun has no other hand-operated lubricant control valve that automatically closes on release of its control by hand. The valve and nozzle may be as described in Specification 963,836 (Fig. 1, not shown, and Fig. 3) or may comprise a hollow rod 24a connected to a valve 25 which is urged by a spring 29 into engagement with a valve seat 33 when the end of the rod is not pressed against a nipple. The outer body 11 of the nozzle assembly is screwed into a pipe 54 passing into a hand grip 56 and engages, via an insert 76, a filter 62 which serves to hold the spring-loaded ball 72 of a valve in the open position. Removal of the nozzle therefore closes the valve and prevents the escape of lubricant. The pipe 54 may pass through the handgrip (Fig. 1, not shown) which extends on one or both sides, and an extension tube may separate the nozzle assembly from the pipe 54. The lubricating gun shown in Fig. 3 has a knob 95 for actuating a screw 94 which, when screwed in closes a valve 93 and opens a valve 97 to permit the passage of lubricant and when screwed out allows the valve 97 to be closed by a spring 98, cutting off the supply of lubricant, and the valve 93 to be opened venting the passages leading to the nozzle to a chamber 96 open to atmosphere.

Abstract: 1310488 Refining lubricating oils TEXACO DEVELOPMENT CORP 9 Sept 1971 [6 Oct 1970] 42023/71 Heading C5E Lubricating oils are made by solvent extracting a vacuum distillate or deasphalted residuum to produce a raffinate and an aromatic extract, hydrorefining the extract, using a catalyst comprising a Group VIII metal or a compound thereof supported on a crystalline aluminosilicate of reduced alkali metal content, combining the hydrorefined extract with the raffinate or recycling it to the solvent extraction, and solvent dewaxing the product oil. The solvent extraction refining is carried out using furfuryl, phenol, dichloroethyl ether or N- methyl-2-pyrrolidone. The extract is hydrorefined to increase its viscosity index e.g. at 600-900‹ F. and 800-5000 p.s.i.g. The hydrorefining can be carried out in a single stage, e.g. using a catalyst comprising Ni and W on a support consisting of a decationized zeolite Y, silica and alumina, or in two stages-first to saturate aromatics using a catalyst on alumina and then to hydrocrack using a catalyst such as Pt or Pd, together with rhenium or of nickel together with rhenium on a support comprising a low alkali metal zeolite together with silica and alumina. Cracking during hydrorefining can be reduced by including 0À1-2% ammonia or carbon monoxide in the hydrogen. The product oil can be hydrofinished, e.g. at 400- 650‹ F. and 400-1500 p.s.i.g. before or after the solvent dewaxing.

Title: Computer display terminals
IPC: G06F3/153
Filed: 1973-09-11
Abstract: 1446643 Display terminal COMPUTEK Inc 11 Sept 1973 42767/73 Heading G4A A display terminal includes a processor 18 (Fig. 2) receiving instructions from for example a keyboard for processing of data, the processed data being displayed on for example a CRT display, a common data bus being used for the instruction and display data in a time multiplexed manner (the single bus being shown as two separate buses 12, 14 in Fig. 2). An input/ output unit is provided as an interface between the terminal and peripheral devices such as a printer and tape cassette. As described, command signals are applied to source bus 12 from a keyboard or peripheral and processor bus operator 30 accepts data from the source bus, modifies it in accordance with instructions from micro-instruction decoder 36 and returns the processed data to the destination bus 14 for display. In each cycle there is a source and destination phase for the data bus, in the source phase a control signal SA indicating that the 5-bit address on the address bus represents the device which is to read data on to the bus and a control signal SR indicating that the processor is reading the data on the bus into a register and in the destination phase a control signal DA indicating that the 5-bit address represents a device which is to read data from the bus and a control signal DW generated by the processor indicating that the processed data is ready to be read. If, for example, a transfer instruction comprising 5 bits representing the destination address, 6 bits representing a modification and 5 bits representing the source address is extracted from firmware 74, a class of micro instruction decoder (64, Fig. 3, not shown) enables gating (68) to feed the source address bits to address bus drivers (66). When the source device places its output on the data bus, the bus register is loaded with data (possibly modified). In their destination phase address buffers (72) apply a destination address to drivers (66) and the selected device reads the data. If a literal load instruction is to be performed 5 bits represent the destination address, a particular bit is set to one (this being detected by the decoder (64)) and the remaining 10 bits represent data to be transmitted to the data bus. During the first phase no transmission occurs, the decoder enabling literal load gating (88) and destination gating during the destination phase. Skip logic increments the address for the firmware after each instruction. After a test instruction the address is incremented by 2 if the conditions are satisfied and by one otherwise to access a test wait instruction which is repeated until the test conditions are satisfied. Micro programmes may be provided to move a cursor on the cathode-ray tube display right, left, up or down and to insert or delete characters of the cursor position. Lines of displayed data may also be erased or rolled up or down and pages may be erased, with or without protected data.
