Abstract: 1,119,626. Testing data stores. GENERAL PRECISION SYSTEMS Inc. 3 Feb., 1967 [12 July, 1966], No. 5325/67. Heading G4C. In a system for checking the operation of a memory in which a sequence of bits are written into the memory, read therefrom and compared with the original sequence, the detection of an error condition causes disruption of the above operations. In particular, the " error " bit over-writes the corresponding bit of the original sequence. As shown (Fig. 1), bits from a sequence of bits circulating in a shift register 12 having a feed back loop 14 are written into a memory 25 which preferably comprises a magnetic disc. Subsequently, this sequence of bits is read from the memory and compared in a compare logic unit 40 with the original sequence still circulating in register 12. On detecting a mismatch condition, an error indicating flip-flop 42 is set whereby the supply of clock pulses from source 20 to register 12 is interrupted and the read mode of control circuit 26 is inhibited. At the same time, the " error " bit read from memory 25 over-writes the original bit in the adjacent stage (Bn-1) of the register 12. A display panel 45 comprising lamps 46 indicates the binary states of the stages of the register. The compare logic unit may comprise a circuit illustrated in Fig. 5 (not shown) and consisting of AND and OR-gates and a single inverter. In a preferred embodiment (Fig. 6, not shown), a plurality of compare logic units each connected to a different stage of the register 12 are provided whereby simultaneous checking of the operation of a plurality of storage tracks and their read/write circuitry may be effected. Checking may be performed in selected portions only of a track, other portions being reserved for data (Fig. 8, not shown).

Abstract: 842,903. Washing granular materials. PITTSBURGH CONSOLIDATION COAL CO. Feb. 18, 1957, No. 5406/57. Class 82(2) A sink-and-float method of separation in a conical vessel wherein there is introduced a concentrated slurry of heavy medium at the top of the vessel and clean water at a plurality of levels at the periphery of the vessel comprises establishing three contiguous, horizontal, zones, continuously measuring the differential hydrostatic pressure across the central zone, and regulating the clean water supply in response to the deviation of the measured differential pressure from a predetermined value. As shown, a conical vessel 10 has a concentrated slurry of heavy medium supplied through a pipe 58 and clean water at a plurality of levels through pipes 30 having control valves 91-95. The separating liquid is divided into three zones by pressure impulse conduits 86, 87 in open communication with the liquid, the zone above the conduit 86 comprising pure water, the zone below the conduit 87 being at a specific gravity below that of separation, and the zone between being at the desired gravity of separation. The conduits 86, 87 are connected to a differential pressure indicator 88 driving a recorder controller 90 preferably of the pneumatic type which controls the valves 91-98 by air pressure. Any deviation of the differential pressure from a predetermined value results in a decrease or increase in the amount of clean water supplied and. so the specific gravity in the zone between the conduits is maintained constant. The air pressure in the pneumatic system to the valves may be used to indicate the amount, of heavy medium to' be added to the slurry. The cone may be divided into more than three zones by the use of additional pressure conduits and control gear (Fig. 5, not shown). It is stated that the gravity in the desired zone may be maintained within Œ 0.01 unit of the predetermined value.

Title: Mechanism for driving an elongate tape
IPC: G11B15/38
Filed: 1973-02-05
Abstract: 1369417 Recording and playback; rewinding tape AMPEX CORP 5 Feb 1973 [14 Feb 1972] 5617/73 Heading G5R  In a tape transport including two vacuum buffer chambers 54, 66 containing tape loops 56, 70 whose length is regulated, high speed tape transport is effected by disengaging the normal driving means 26 between the chambers 54, 66 from the tape, and tensioning the loops 56, 70 differently. Thus, the interior of chamber 66 is partially vented to atmosphere through a valved conduit 112 connecting orifices 114, 116, to produce high-speed rewind from machine reel 16 to removable file reel 14. Capstan 26, which normally has vacuum applied to it, has positive pressure applied, and becomes an air bearing. The tape thus traverses from chamber 66 to chamber 54; and since reel motors 18, 20 are servo-controlled to maintain loops 56, 70 at constant length, tape also transfers from reel 16 to reel 14. The loop lengths are sensed by point sensors 80-90, 94-104 and linear sensors 76, 78, 90, 92, which may be optical. The loop adjacent the take-up reel is always kept the longer: thus loops 56, 70 are maintained adjacent sensors 82, 102 for transport from reel 16 to reel 14. If reel 16 is incapable of rotating sufficiently fast, loop 70 will rise and cover orifice 116 stopping venting of chamber 66; if reel 14 is incapable of rotating sufficiently fast, the loop 56 will drop and expose an orifice 118, causing venting of chamber 54 also, via valved conduit 120. Vacuum pockets 42, 50 are also provided for tensioning the tape against the capstan 26 and air bearings 28-32. The above mode of transport is only used when reel 16 has a predetermined amount of tape thereon as detected by a sensor 106.
