Patent GB-434833-A (GB)
Abstract: 434,833. Moulding-machines. FOUNDRY EQUIPMENT, Ltd., CORRIE, J. B., and BEECH, A. S., 15, Victoria Street, Westminster, FIELDING, F. B., and ROWLES, R. V., c/o Fielding & Platt, Ltd., Atlas Works, Gloucester. April 11, 1934, No. 10950. [Class 83 (i)] A moulding-machine, for producing boxless moulds, of the type having a swinging head 22 and a swinging pattem-plate frame 34 has a platen 40 moved within the bottom box 26, by a fluid-operated cylinder 46 on a fixed cylinder 42, to compress the mould and the box 26 is moved down to strip the mould by a plunger 57 in the cylinder 42. The box 26 is filled with sand and the frame 34 is swung about its pivot 36 until a roller 125 on its free end snaps over an adjustable support 120. The frame has one support 134, Fig. 7, which is fixed and two 132, 133 which are vertically and horizontally adjustable to carry the pattern plate 38 on which rests the upper box 27. This is then filled with sand and the head 22 is swung into operative position by means of a handle 88, movable in slots 98, 99 to operate a locking bolt 110, Fig. 11, and, by means of a wedge 105, abutments 96, 106, and spring pin 90, to force the head up and press the engaging surfaces 85, 86, Fig. 1, firmly together. Fluid is then admitted, by passages in the cylinder 42, Fig. 2, to a space 66 and thus lift cylinder 46, platen 40 and, by reason of sliding fit 62, the box 26, its weight being counterbalanced by constant pressure in space 58 acting through rods 56, 30 and 28, Fig. 1. The sand is thereby compressed and pins 147, 148 on the box 27 engage adjustable spring jaws 144 so that when the platen 40 is moved down by constant pressure in the space 53, Fig. 2, the box 27 is retained. A fluid operated vibrator 128, Fig. 7, arranged in a recess of the frame 34 is operated during drawing, preferably being started and stopped automatically by the movements of the press. The pattern &c. is then swung aside and the cylinder 46 &c. again raised to assemble the mould, spring pressed clips 152, Fig. 1, on the box 27 engaging hooks 162 on the box 26. Fluid is then admitted to space 256, Fig. 2, to force down rods 56, 30, 28 and boxes 26, 27 thus stripping the mould. The upward movement of the cylinder 46 is limited by a flange 83 engaging an externally threaded ring 82, feathered to slide but not rotate on the cylinder 46, this ring being screwed into a nut 78 which is held against axial movement in the frame 17 and can be rotated by teeth 178 and a pinion to adjust the position. Stops 43, and 170, Fig. 1, are also provided.

Title: Method and device for producing binary signals from an original by means of a television camera
IPC: H04N1/403
Filed: 1975-10-24
Abstract: 1518177 Facsimile LICENTIA PATENT VERWALTUNGS GmbH 24 Oct 1975 [24 Oct 1974] 43792/75 Heading H4F When an original black and white document is scanned by a television camera the video signal contains undesired grey level amplitudes (for example due to uneven illumination or coloration of the document, differential spatial sensitivity of the camera tube and optics, and the finite size of the electron beam when scanning fine detail) which should be removed prior to transmission via a digital channel, e.g. in a high speed facsimile system using a telephone channel. A first variable threshold signal 4 is therefore produced by passing the signal 1 through a low-pass filter with a cut-off frequency of 2-3 times line frequency, and the amplitudes of signals 1 and 4 are compared to produce a corresponding two-level signal 5. During the blanking period 2 the filter is preferably rendered inoperable. If a substantial part of a line contains no image detail, signals I and 4 tend to become equal and the signal 5 may assume the incorrect value. A second threshold signal 7, of fixed waveform and an amplitude falling between these for black and white, is therefore produced in response to the blanking or sync signals and is compared with the first threshold signal 4 (6) to give a signal 8 of one of two levels depending on whether the line is white or black. Signals 5 and 8 form the inputs to an OR gate producing the final two level signal for transmission. The signal 7 may be at a fixed DC level, but, as shown, includes line and field frequency components so that it corresponds closely to the signal obtained by scanning a uniform grey line on the document.

Title: Improvements relating to Data Recording/Transmission Systems
Inventor: GWILLIM DAVID THOMAS
IPC: H04L13/08
Filed: 1965-10-15
Abstract: 1,156,503. Digital data storage. PLESSEY CO. Ltd. 4 Oct., 1966 [15 Oct., 1965], No. 43907/65. Heading G4C. [Also in Division H4] A system in which data is recorded or transmitted in the form of significant changes in state includes recognition means responsive to the absence in the data of a change in state for a period corresponding to a predetermined number of elementary bits, and effective to introduce a further change in state in the data in addition to the elementary bits for self-clocking purposes. Data processing equipment 1 applies bits to lines 2, 3. The "1's" are applied to counter 9 which enables AND gate 10, and inhibits AND gate 13 when a predetermined number is reached. A "0" signal on line 3 passes OR gate 5 to a flux reversing circuit 6 which reverses the direction of current fed to the writing head 7 from an amplifier 8. If a predetermined number of consecutive "1's" occurs the signal from counter 9 causes a "data accept" signal on line 4 to cease thus stopping data transmission and causes a pulse from clock 11 to pass via OR gate 5 to cause a flux reversal and to reset counter 9. Data read or received is applied to a timing circuit arrangement 17 wherein "1" outputs are fed successively to lines 18, 18(1)-18(N) and "0" bits to line 23. On timing N successive "1" bits the signal on line 18(N) acts to inhibit the following, self-synchronizing, "0" bit, the timing circuit only timing intervals between flux reversals. The data can be recorded on magnetic tape or fed to a data transmission line.

Abstract: 1467494 Valves GAZ DE FRANCE 10 Oct 1974 [11 Oct 1973] 43988/74 Heading F2V [Also in Division F4] An arrangement for the prevention or minimisation of over-pressures due to sudden interruption in the flow of a compressible fluid, which are caused by the closure of an electrical valve 6 situated along a main gas pipe 1 comprises a pressure regulator 5, mounted on the pipeupstream of the valve, the closing response time of which is longer than that of the valve, a venturi which communicates with that section of the pipe which is situated between the valve and the regulator, and a buffer reservoir 7 which is in permanent communication with the section of pipe, via the venturi, the regulator also forming the venturi. Regulator valve 5 comprises a body 5a with a partition 5z, a valve closure 5c actuated by a rod 5d and a valve seat 5b, providing line contact 5i, and forming a convergentdivergent venturi which is connected to reservoir 7 by passages 5j and pipe 8. In operation, with a burner 2 operating, valves 4, 5 and 6 are open and due to the flow through the venturi a vacuum is created in reservoir 7. When electrical valve 6 is closed, the increase of pressure in pipe 1 is compensated for by the vacuum in the reservoir. When the burner is put back into operation, since the gas pressure is close to the normal supply, pressure valve 5 will open more rapidly. The flow of gas through the venturi may be in a radial direction Fig. 2, or it may be substantially axially Fig. 3. The regulator 5, Fig. 3 comprises a hollow control rod 5d attached to a diaphragm 5r, which acts against a return spring 5s.
