Title: Data handling apparatus for fixed length records
IPC: G11C19/08
Filed: 1975-11-26
Abstract: 1527913 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 26 Nov 1975 [7 March 1975] 48504/75 Heading H3B [Also in Division G4] Apparatus for serially storing and dynamically permuting fixed length records comprises a ladder arrangement of shift registers loops L0-L4 (Fig. 1c) interconnected by switches S1-S4 such that data in adjacent loops may be exchanged and an input/output switch S0 for reading in and writing out records, a record being transmitted from, e.g. input loop I/O to the last loop L4 by successive operation of switches S0-S4. The shift register may comprise charge coupled devices and switches or preferably magnetic bubble domain devices in which case data at input B (Fig. 1B) is directed to output C if, with the data at position b at phase 3 of control field H a current is passed to conductor 14B during subsequent phases 4, 1 to direct the bubble to position 4 of element 18. At phase 2 it travels to position a and consequently subsequently to output C. Data at input A is similarly directed by current in conductor 14A to output D. If conductors 14A, 14B are not activated data from input A, B flows to outputs C, D respectively. The ladder is fully loaded in five time periods by operating the switches for the following time: S0 for times 0-5, S 1 for times ¢-4¢, S2 for times 1-4, S3 for times 1¢-3¢, S4 for times 2-3, the ladder operating as a stack (i.e. first in/last out). The arrangement is such that whenever a record is accessed and rewritten it migrates to the top of the stack and consequently is assigned the highest probability of immediate reuse (most recently used algorithm).

Dec. 28, 1962 [Jan. 12, 1962; Nov. 5, 1962], No. 48887/62. Headings B3F and B3V. In a continuous casting apparatus in which the melt is poured into the mould 3 from a main ladle 1 via an intermediate ladle 2, there are devices 7, Fig. 2, responsive to variations in weight of the intermediate ladle due to changes of level of the molten metal therein, which control automatically the flow of metal from the main ladle to the intermediate ladle, and devices 11, 12 which automatically maintain the level of the melt in the moulds by regulating the flow of metal from the intermediate ladle to the moulds. The devices 7 on which the intermediate ladle 2 rests are stress gauges such as elastic, magnetoelastic, capacity, induction, piezoelectric, semi-conductor &c. gauges which transmit signals to a device 9 actuating the stopper 10 of the main ladle 1 in the appropriate sense. The mould level detector 11, 12 is of the photoelectric, ultrasonic, capacity or radio-active type and actuates a device 14 controlling the stopper 15 of the intermediate ladle 2. The intermediate ladle 2 is mounted for vertical adjustment so that the height of the pouring jet may be adjusted, and also for rotary movement so that it may pour into slag pots adjacent the moulds. Each mould comprises long side walls 22, Fig. 5, with short end walls 24 clamped therebetween, and is reciprocable by a cam device 3a, Fig. 1. The secondary cooling zone comprises series of water sprays each series being independently controlled and sprays facing the long sides of the ingots being mounted for pivotal movement so as to cool uniformly the wide faces.

Abstract: 1,098,142. Knitting; drafting; carding engines. A. W. SCHMIDT. Dec. 11, 1964 [Dec. 20, 1963], No. 50557/64. Headings D1C, D1D, D1K and DIN. A pile fabric is knitted on a circular machine by feeding a number or rovings at a variable rate to a carding unit where they are blended and subsequently transferred to the needles of the machine to be incorporated in a base fabric. Two rovings 76, 78 of different colour, quality or other nature are fed by two drawing or drafting sections 72, 74 at a rate which can be controlled to a main cylinder 24 of carding unit which also includes a doffer roll 29 and a fancy wheel 46. The needles of the machine are raised to take a base yarn and to engage in the card cloth of the doffer roll to take bundles of fibres and knit them into the base fabric. The nature of the pile of the fabric can be varied by varying the rate of feed of the drawing sections 72, 74 and this is achieved by driving each independently of the other and both independently of the carding unit which is driven from the ring gear (12) Fig. 8, not shown, on the needle cylinder drive. Each drafting unit comprises a series of spiral and straight gear rollers 100, 102, 104, 106, 108, 110, Fig. 10, which serve to flatten and spread the roving on to the main cylinder 24 of the carding unit. The rollers are driven by an electric motor having a control unit including a rheostat. The rheostat is influenced by pawl and ratchet mechanism periodically actuated as the needle cylinder rotates which causes energization of a solenoid to move a pawl which racks the ratchet wheel influencing the rheostat. Consequently by the provision of reversing dogs, pawls can be rendered operative or inoperative to cause the rheostat to influence the motor to increase and decrease its speed. By increasing the speed of one motor controlling its drafting section and simultaneously decreasing the speed of the other motor controlling its drafting section the total amount of fibres received on the main cylinder can be maintained substantially constant. By feeding fibres of different colours or other characteristics first one and then the other may predominate to produce stripe effects. Other patterns can be achieved and long and short fibres may be interspersed. A third drafting section may feed other fibres which are also intermixed with the fibres from the other sections on the main roller.
