Abstract: 1,238,101. Magnetic storage arrangements. INTERDATA Inc. 26 Feb., 1969 [28 Feb., 1968], No. 10205/69. Heading H3B. In a word organized storage matrix in which magnetic cores 12, Fig. 1, are located at the crossing points of word lines 45-48 and bit lines 15-26, the bit lines are arranged in equal sized groups each allocated to a different bit of a word and connected to respective bit drivers 30-33, and a plurality of words are stored in those cores which extend along a pair of adjacent word lines 45, 46 or 47, 48. Thus the first bit of each word, e.g. "0,0", is stored in a respective core in the first bit line group 15-17 and in the first word line 45 of the pair 45, 46, the second bit of each word, e.g. "0,1", is stored in the corresponding-positioned core in the second bit line group 18-21 but associated with the second word line 46 of the pair 45, 46, and so on, with successive bits registered alternately between the word lines of the pair. Reading and writing is effected by coincident half current switching, the bit drivers and the single word driver 50 being of reversible polarity. Readout of a selected single word is effected by energizing all the bit drivers 30-33 and the word driver 50 in coincidence with the bit drivers energized first to clear noise disturbance; word selection being effected by closing a single bit switch in the group 40-42 and one of a pair of word switches S1, S2. The direction of the bit and word line currents for read out is shown by arrows in Fig. 1, alternate bit drivers 32, 34 and 31, 33 acting as sources and sinks of switching halfcurrent respectively. Each bit switch comprises two transistor switch units 40a, 40b details of which are given in Fig. 3 (not shown), a single bit line in a corresponding position in each group, e.g. lines 15, 18, 21, 24 being connected to a single bit switch through a respective rectifier pair 35. In a modification, Fig. 4, a single transistor switch unit is used for each bit switch by providing additional rectifiers 61, 62. Both the bit and word drivers provide half-currents of reversed direction to that shown for writing a " 1 ", the bit drivers each consisting of two transistors connected to respective sources of forward and reversed polarity and separately gated, Fig. 3 (not shown). For writing a "0" the relevant bit driver is inoperative. A separate sense winding 125, 126, Fig. 5, threads all the cores in a bit line group in such a direction that all the induced voltages are in the same sense, and is connected to a unidirectional sense amplifier 130.

Abstract: 1,238,349. Binary transversal filters. RESEARCH CORP. 20 Aug., 1968 [5 Sept., 1967], No. 39863/68. Addition to 1,196,442. Headings H4R and H3U. A binary transversal filter comprises Fig. 3 a digital shift register 113, to which input pulses are fed and shifted therethrough at a shift rate which is a multiple of the input data rate with different groups of stages fed with shift pulses at different rates. A resistive combining network 125 is connected to the shift register stage outputs to provide the appropriate filter response. In order to reduce distortion one or more analogue integrator circuits may be provided after the binary transversal filter, and/or the resistive network may be modified to provide the effect of an integrator stage following the filter. In order to reduce truncation distortion, due to the finite number of stages employed, the shift rate of the data pulses through the register is varied, e.g. to provide a slow rate of shift at each end of the filter register and a faster rate in the middle or alternatively the clock rate may be varied in accordance with the differential of the filter output to provide a high shift rate, effectively increasing the sampling rate, while the output signal is changing rapidly and a low shift rate while the signal has a low rate of change. For simulation of an even function, having symmetry about a mid point, economy in the resistive network can be obtained by providing common connections from the network to pairs of shift register stages equally spaced from the mid point of the register Fig. 21 (not shown). For dealing with input pulses which occur at irregularly spaced intervals it may be arranged that each pulse initiates its own chain of shift pulses which are used to shift that pulse through the register. The response of the filter may be varied by arranging that each input data pulse produces a train of pulses of a predetermined pattern which is fed to the input of the filter, Fig. 25 (not shown). For the filtering of amplitude modulated samples the samples may be pulse code modulated in binary code and the respective digits of each sample having the same significance fed to respective shift registers the outputs from which are combined in a summing unit either before or after digital to analogue conversion. A band pass filter may be simulated, as shown in Fig. 22, using in phase and quadrature filters 183 and 184 the outputs from which are modulated by quadrature related carriers in modulators 190 and 194 to be combined to produce a single sideband filtered band pass signal at 197. Also described in the use of the filter to produce a real zero interpolation of minimum band width as described in the parent Specification.

Abstract: 1,239,575. Bobbin winding. IVANHOE RESEARCH CORP. 11 June, 1968 [12 June, 1967], No. 27692/68. Heading D1C. [Also in Division F1] The sewing machine bobbin 34 is replenished with thread by rotating the bobbin in situ by a flow of air, a metered length of thread being supplied from a cop 38 and blown through a thread injection tube 44 to present one end of the thread to the rotating bobbin to be entrained thereby. The bobbin, which is of plastics material including a hub 72 of low friction plastics material, has turbine vanes 36 formed on the outer surface of one flange 37, small diameter wires 74 being provided at the hub to form thread entraining elements. The bobbin 34 and its case 28 are located in a stationary basket (24, fig. 3 not shown) within a rotating or oscillating hook. When a workpiece W has been sewn, exhausting the bobbin thread, the machine is stopped, by means not described, with the needle raised and solenoid valves 63, 67 energised to cause a piston in cylinder 48 to raise a block 46 carrying the thread injection tube 44 through which air flows from conduit 68, the free end of the tube 44 entering aligned holes in the now stationary hook, the basket 24 and case 28. Air flowing from conduit 65 has mean while accelerated bobbin 34 to a high rotational speed, the thread end presented by the tube 44 engaging and being drawn in to the bobbin after a thread clamp 54 has been released by passing above the end of a fixed guide rail 56. When the bobbin has wound on the length of thread metered out by device 40 to the taut thread actuates switch 75 to close valve 67. As the block 46 descends the clamp 56 engages rail 56 and clamps the thread while a hook 76 on the block actuates a lever 78 to swing a thread positioner arm 85, 86 to pull the thread beneath the bobbin case tension spring 32 and place the thread in a position to be picked up when stitching recommences. Further descent of the block 46 rotates the twisted strip 100 to cause blade 95 to cut the thread, a switch 107 being finally operated to close valve 63 and cut the air supply to the bobbin and the thread injection tube.

Abstract: A method of making a gas permeable material having a diffusive gas permeability at 0.21 atmosphere diffusive driving force in the range of about 0.5x105 cm3/100 square inches/day to about 2x105 cm3/100 square inches/day. The method comprises the step of coating a pattern of spots of a gas impermeable material onto a porous substrate, followed by a step of enlarging the pattern of spots to cover greater than about 95% of the porous substrate such that the gas permeability occurs only through openings between the pattern of spots. The gas impermeable material is preferably a hot melt adhesive and the porous substrate is preferably a nonwoven. The step of enlarging the pattern of spots includes smearing substantially circular spots into oblong spots as the pattern of spots is printed onto the porous substrate until the oblong spots partially overlap. The smearing is achieved by operating a printing screen at a surface speed higher than a draw rate of the porous substrate. Alternatively, the step of enlarging the pattern of spots includes calendering through a fixed gap the porous substrate after the pattern of spots is coated thereon.
