Filed: 1974-09-18
Abstract: 1459613 Stack storage system INTERNATIONAL BUSINESS MACHINES CORP 18 Sept 1974 [18 Oct 1973] 40599/74 Heading G4C In a data processing system in which two lastin, first-out stacks are built up from opposite ends of a high speed store and in which means are provided to roll-out the contents of the stacks to a lower speed main store when they become full and to roll-in previously rolled-out stacks when a stack becomes empty, means are provided to address any selected entry in a part of one of the stacks in the high speed store. As described all operations are performed under microprogram control and a high speed store having 16 registers and two pointer registers are provided to establish the stacks. The stack registers may be formed by addresses 0- 15 in a larger high speed store so that only 4 bits are required to address the stacks, the remaining address bits being 0 for stack operations. A LO stack for operands is built up from address 15 towards address O with a LO pointer register pointing to the next free register. A HI stack for operators is similarly established from address 0 towards address 15, each entry pushed on to stack HI however including, as well as an operator, the current LO pointer value. Whenever an entry from stack HI is popped the operator is fed to an operator register for use, and the LO pointer value is fed to the LO pointer register to access the operands associated with the popped operator so that other more recent operands need not be popped to access the required operands. Roll-out of the contents of the high speed store and the pointer registers is signalled whenever HI pointer >LO pointer and a push operation on either stack is signalled, the push being performed following roll-out. Roll-in is signalled whenever, as a result of a pop operation from either stack, the appropriate pointer decrements below 0 and increments above 15 respectively. The pop operation is performed after the roll-in. Arrangements are provided to address directly up to the four most recent entries in stack LO. This is achieved by decrementing the LO pointer by up to four to reserve a directly addressable area, a roll-out being signalled if the LO pointer becomes <HI pointer to prevent the reserved area overlapping into the HI stack. If roll-out occurs the reserve process is repeated on the, now empty, high speed store. To address the reserved area the LO pointer contents are fed to the high speed store selectively through one of four incrementers which increase the pointer by 1, 2, 3, and 4 respectively to allow direct access to an addressed register.

Filed: 1964-10-08
Abstract: 1,035,549. Stoppering. PNEUMATIC SCALE CORPORATION Ltd. Oct. 8, 1964. No. 41089/64. Heading B8T. Screw caps 12, Fig. 1, are fed by gravity down a shoot 10, and at the delivery end a single closure is retained by a spring-urged pivoted arm 46 and is engaged and withdrawn by the neck of a container carried below the shoot by a conveyer 14. A line of closures is held back from the delivery end by a pivoted pawl 18 and, prior to a container reaching this end, it is detected and the pawl operated to release a single closure. The closures are guided on the shoot by side rails 30, 31, Fig. 4 (not shown), and are held down by an adjustable top rail 34 pivoted about a rod 39. The lower end of the shoot has a steeper inclination and an extension 60 preventing lateral displacement of the closure when it is withdrawn by the container neck; an adjustable top rail 64 at the lower end carries a downwardly urged pivoted arm 70 with a roller 68 which ensures the placing of the closure in a vertical position on the container. The container detecting apparatus includes an air jet 168, Fig. 9 (not shown), normally delivering a stream of air on to a curved vane 166 whereby a pivoted member 156 is urged to close an air escape nozzle 148 of a pneumatic control system; pressure air is then caused to flow through a line 100 whereby a pilot valve 94, Fig. 7 (not shown), at one end of an air cylinder 88 is forced downwardly and air is supplied to the cylinder to move a piston 92 forwardly and to urge the pawl 18 to the closure holding position. When the air stream to the vane is interrupted by a container neck, the member 156 is spring urged away from the nozzle 148, the air supply through line 100 interrupted, and a spring 98 forces the pilot valve 94 upwardly whereby an air supply from a line 126 is fed to the opposite side of the piston 92. The latter is thus retracted and the pawl 18 operated to release a closure. In a modification the containers are detected by a feeler arm extending across their paths; the arm is moved by a container neck to operate a switch controlling a solenoid valve which cuts off the supply to the line 100.

Abstract: 1,254,075. Spinning yarns; drawing frames; gill-boxes. KANEGAFUCHI BOSEKI K.K. 22 Aug., 1969 [22 Aug., 1968], No. 42101/69. Headings D1F and DIN. In a process of worsted spinning the wool is subjected to the steps of washing, drying and storing in a container; carding to form sliver; drafting, backwashing; drying; gilling; a second drafting; combing; "shuffling" and then gilling by a high-speed gill to form worsted tops. The "shuffling" is intended to correct the fibre orientation in slivers delivered from combers (in which, due to partial overlap of nipped sliver at regular intervals, irregularities in thickness occur) and thereby eliminate repeated drafting conventionally employed for such correction: shuffle is effected as a result of speed differential between top and bottom members acting on the slivers in a drafting zone. As shown in Fig. 1, fibres pass through a woolwashing machine 1 and dryer 2 to be stored in a wool bin 3 pending advancement to the hoppers of a group of carding engines 5-5n. The overlapping slivers SA delivered by the cards are passed by conveyor belt 6 to a drawing frame 7 having automatic canexchange apparatus and cans 8 for receiving drafted sliver SB which then passes through a backwasher 9, dryer 10, gill-box 11 delivering slivers SC which pass to drawing frame 12 delivering slivers SD into cans 13 supplying combers 14-14n. Combed slivers SE are shuffled by apparatus 16 to form sliver SF which is gilled by high-speed gill 17 and condensed as sliver SG for take-up as worsted top 18. The frame 7 comprises in two successive drafting zones sets of top and bottom control plate rollers in vertical and horizontal partly overlapping relation and having peripheral pointed teeth. Shuffling apparatus linking the combers and the high-speed gill comprises, in one or two drafting zones, sets of top and bottom, overlapping, toothed and sharp edged plate rollers 50 and 50', Fig. 5, or sets of top, fluted, knurled or saw-toothed rollers and bottom, plain or fluted &c., rollers 61 and 62 co-operating with an apron 65, Fig. 6, or both sets in combination, Fig. 7 (not shown).
