Patent GB-1248705-A (GB)
Title: A computer when programmed to verify the transmission of multiplexed seismic data
IPC: G06F11/14
Filed: 1969-12-16
Abstract: 1,248,705. Programmed data processor. PETTY GEOPHYSICAL ENG. CO. 16 Dec., 1969 [17 Dec., 1968], No. 61198/69. Heading G4A. Computer programmed to check seismic data transfers successive individual data scans from a store, examines each scan to determine whether it contains a complete set of data, substitutes a previously examined correct scan for a successive scan that does not contain a complete set of data, and transfers the data scans to storage. Data scans are stored in block form on magnetic tape. The tape has a block track, 18 data tracks, a parity track and a clock track. The first word on tape before a set of data scans has zeros in all tracks but the clock and parity tracks. The first word of each set has a one in the block track, zeros in the word tracks and ones in the parity and clock tracks. The following words have zero in the block track, have data representing the output of several data channels arranged in multiplexed form and have a coded binary gain control value G. The next data scan is defined by a one in the block track of the first work and by an address in the first word indicating the time difference between the occurrence of the two successive scans. Data from the tape is fed to an initial storage 38 (Fig. 3) and to an identifier 39 (Figs. 4, 5A, not shown) which starts a counter on receiving the block bit at the start of a scan and counts the number of zeros following the initial block bit. A preset value may be subtracted from the counter and the result supplied to a zeros detector or the counter may be counted down from a preset value and the result applied to a zeros detector. If the scans are the correct length a transfer gate is opened to pass the data to an intermediate storage 42. If the length is correct a prior word is obtained from final storage 45 and supplied to the intermediate storage 42. In either case storage 38 is reset via delay 43. The work from the initial storage is parity checked and if correct is supplied to store 45. If incorrect a prior word is obtained from store 45, supplied to word register 46 and checked for parity. To ensure that the final store has a word to supply an initial scan inhibit causes the first data scan to be supplied to the storage 45. The parity checker may comprise a tree of exclusive NOR circuits (Fig. 7A, not shown) connected in special arrays (Fig. 7, not shown). A further identifier circuit (Fig. 5, not shown) may have the word detector previously described and have a comparator checking the block address included in the first work of each scan with an incremented address generator which may be incremented by clock pulses. Zero detect gates coupled to a comparator may feed an AND gate to produce a YES or TRANSFER signal.

Patent GB-643324-A (GB)
Abstract: 643,324. Electromagnetic ammeters and voltmeters. GREIBACH, E. H. Feb. 18, 1947, No. 4715. Convention date, Feb. 20, 1946. [Class 37] [Also in Group XIX] In a moving coil instrument the moving system and magnetic core are formed as a self-supporting detachable unit, the moving coil being supported by a bifilar suspension tensioned by cantilever springs. To the polepieces 36, Fig. 5, are attached two' 'flanged brass tubular mounts 62, 63 into which can be inserted a brass tube 61 carrying the moving coil 31 and its suspensions and also the magnetic core 37. The moving coil 31 is supported by two bifilar suspensions 51 tensioned by cantilever springs 76, each of which consists of a pair of flat opposite-handed spirals. The springs may be of bimetal for temperature compensation. The springs 76 are mounted in upper and lower suspension heads 71, 72 which fit into screwed adjusting collars 74 by which the tension of the bifilar suspensions may be adjusted. Each suspension head 71, 72 may be rotated relatively to its adjusting collar 74 without disturbing it in its axially adjusted position so as to effect zero adjustment of the moving coil 31 and its pointer. The bifilar suspension 51 may be formed from a rolled strip with thickened edges 53-1, 54-1, Fig. 7, forming the two wires joined by a thin web 51-1 which may be weakened by perforations 51-2. The moving coil 31 may consist of a number of winding sections, the suspension members serving as connecting leads. The air gap extends over an arc about 50 per cent greater than the maximum deflection range of the coil so that the coil always moves in a uniform field. Magnetic impurities in the moving coil do not then produce any torque and their effect on the sensitivity of the instrument is eliminated. The instrument is supported in its case by a ring of rubber-like material.

Title: Perforating Sheets
IPC: B26F1/24
Filed: 1978-07-15
Abstract: The invention concerns forming of perforations in heat curable resin- impregnated fibrous sheets. An uncured impregnated sheet 1 is held, e.g., between top and bottom plates whilst hot needles 13 or the like pierce it. The needles stay in position long enough to at least partially cure the resin immediately surrounding them, and are then withdrawn. The curing of the resin surrounding the perforations prevents ingress of hot fluid resin during subsequent moulding and curing operations. <IMAGE>
