Abstract: 1292645 Reticulated foam containing laminates J WINKLER 7 Nov 1969 [8 Nov 1968] 54724/69 Heading B5N [Also in Divisions C1 and C7] A laminate is made by bonding a reticulated, carbon particle coated, flexible, organic, polymeric foam material to a woven rayon fabric or between a rigid acoustical tile and a coloured fabric, the foam material being made by permeating an open cell, flexible, organic, polymeric foam material in a closed system with a mixture comprising a stable diluent gas or ethylenically unsaturated gaseous hydrocarbon and a gaseous hydrocarbon which will explosively decompose to its elements in the absence of oxygen with the production of particulate carbon and hydrogen when exposed to alocalized concentration of energy, and thereafter exploding said gaseous hydrocarbon by generating a localized concentration of energy in said closed system. The open cell foam is preferably a polyurethane. The gaseous hydrocarbon may be acetylene or a derivative thereof. The inert diluent gas may be helium or nitrogen. The ethylenically unsaturated hydrocarbon may be ethylene or propylene. The localized concentration of energy may be in the form of an electric spark, a laser beam; X-rays, γ-rays or electron beams, alternatively, detonation caps of mercury fulminate or lead azide may be employed. The colour of the reticulated product may be varied by suspending powdery pigments or metals in the mixture. The products of the invention may be used for lining fabrics, as household sponges or in the preparation of acoustical tiles.

Abstract: 1454530 Mineral-mining installations GEWERKSCHAFT EISENHUTTE WESTFALIA 28 Nov 1973 [29 Nov 1972] 55145/73 Heading E1F [Also in Division F1] Rams 11, Fig. 1, which advance a conveyor 10' in a mine working, are extended in steps by a metering device 15. To extend the rams, pressure fluid from a source P is admitted to a chamber 21 of the device 15 when the slide of a valve 17 is moved to the left by pressure in a line 24. As fluid enters the chamber 21, a measured volume of fluid is forced from a chamber 20 through lines 14 into the rams 11 by a floating piston 16. Operation of a timing device allows the slide of valve 17 to return to the position shown when the chamber 20 is empty and as the chamber is refilled fluid from the chamber 21 is fed to the rams. This completes one cycle of operation. The valve 17 is controlled by a valve 25 and a ram 29, 30. The latter is actuated pneumatically through a line 27 when an appropriate button is pressed. The piston rod 32 acts on a rod 33 to push the slide of valve 25 to the left. This admits pressure fluid to the line 24 through lines 18, 26. When the line ST is depressurized the pressure in the ram 29, 30 leaks away through a throttle 37 and a check valve 38. The device 15 may control only one ram or several. Fig. 3 (not shown), illustrates an automatic control system incorporating time delays which increase in 5 second steps.

Filed: 1973-11-29
Abstract: 1407158 Lifts HITACHI Ltd 29 Nov 1973 [1 Dec 1972] 55438/73 Heading B8L An elevator includes a car 14 mounted in a framework 5 hung by a wire rope 3 and guided by rollers along guide rails fixed to an elevator shaft, the car 14 being mounted in the framework 5 for horizontal oscillation relative to the framework 5. In the embodiment of Fig. 3, the car 14 is secured to a frame 30, supported by rods 34 which are suspended through a spring fitting 36, 38 from an upper frame 32 of the framework 5, whereby transversal vibrations of the framework 5 are not transmitted to the car 14. The car 14 is prevented from striking against the framework 5, when the car swings excessively sideways due to an external cause, by stoppers interposed between the frame 30 and framework 5, and comprising rubber projections on the framework 5 being received with lateral clearance within depending cylindrical portions on the frame 30. Alternatively, excessive lateral swing may be restricted by cut outs in the floor of the car 14 receiving slings which are part of the framework 5. Stoppers are provided on the framework 5 above the car 14 to prevent any excessive jumping of the car within the framework if the rising framework is suddenly stopped. In the embodiment of Fig. 9, the car 14 is supported in the framework 5 on bolsters 100 comprising ball bearings permitting relative horizontal movement of car and framework. The bearing plates 102, 104 to either side of the ball race 106 are respectively secured through rubber dampers 108, 110 to the car 14 and framework 5. Excessive lateral swing of the car 14 is restricted by either stoppers 40 or 112  interposed between the car and framework, and excessive vertical jumping of the car is prevented by either stoppers 70 on the framework 5 or a stopper bolt 114 with stopper head 115, secured to the car and extending through the framework. An electromagnet may be provided to prevent movement between the car and framework when the car is being loaded or unloaded.

Title: Communication terminals
IPC: G06F15/02
Filed: 1972-12-01
Abstract: 1418479 CRT displays DIGI-LOG SYSTEMS Inc 1 Dec 1972 [9 Aug 1972] 55539/72 Heading H4T [Also in Division G4] A remote terminal comprises a keyboard 2 and an acoustic coupler 4 linked to a computer by a telephone 6-8, and incorporates a conventional TV set 9 for displaying data either from the keyboard or from the computer. Depression of a key 34, Fig. 1A causes a diode matrix 36 to send a coded signal to a converter 44 (a parity generator being activated by the depression of certain keys) which, in the absence of an invalid data signal 52, controls a FSK oscillator to produce one of two tones corresponding to the binary digits of the data signal 30 (now in ASC11 code): this passes via a filter 32 to a speaker 12 in the receiver 6.  When the incoming tone signal from the computer reaches the earpiece of receiver 6 it is detected by a microphone 10, Fig. 1A, then amplified, filtered and passed to a frequency discriminator 18; detection of the carrier allows the recovered data signals to pass through a gate 22 to the display. There are two display modes: (1) the data is transmitted to the computer, which returns it to the terminal for display to check that it has been correctly received; (2) the data is displayed directly from the keyboard (switch HDX, closed in Fig. 1A). In either case the data 64 passes via a converter 62 to a latch 70 whose output 88 passes to a register 90, Fig. 1B, which stores a display "page" containing 8 lines of 32 characters each of 6 bits (there may be other page stores, e.g. 96). The page store output is gated to a "line" register 92 (32 characters) and from there to a character generator 98 controlled by a binary display line selection signal 100: this outputs character signals, each in the form of a 5 Î 7 dot matrix, which pass via a parallel/series converter 104 to a mixer 112 to be combined with vertical and horizontal sync signals 114, 116 and a cursor signal (indicating next character to be displayed). The output from 112 passes to a modulator 118 which shifts the mixed signal frequency to the RF range and makes it available at the antenna terminals of the TV set. A CRT monitor may be used instead by means of a unit gain buffer 122: to allow rapid connection of either the CRT or the TV, a "multiplexing" arrangement, Figs. 2, 3 (not shown), is employed. Timing and control circuitry 84 is also described for providing clock pulses and for controlling the loading and transfer of the various registers. A phase lock loop 132-140 provides master timing signals.

Abstract: 1,247,910. Spark-erosion. HAMMOND MACHINERY BUILDERS Inc. 27 Nov., 1968 [4 Dec., 1967], No. 56335/68. Heading B3V. [Also in Division C7] In an electrochemical grinding machine, a sensing electrode and associated circuitry control energization of a cleaning electrode so as to remove waste material which accumulates on the surface of a grinding device comprising non- electrically conductive abrasive grains protruding from an electrically conductive matrix. The grinding device may be a wheel, disc or belt. The removal of waste may be by electrolysis or by spark discharge. The current supplied to the cleaning electrode may be fluctuating or intermittent and may be of constant or alternating polarity. Fig. 3 shows a rotating electrochemical grinding wheel 11, workpiece W, cleaning electrode 22 and sensing electrode 29. A control C measures the resistance between the sensing electrode 29 and the matrix of the grinding wheel and automatically controls energization of the cleaning electrode by controlling a switch 26. When the workpiece is retracted, a microswitch 25 opens the circuit containing the cleaning electrode. The wheel, in addition to being rotated, may be oscillated relative to the cleaning electrode. Alternatively, the cleaning electrode may be oscillated. There may be a common supply of electrolyte, e.g. from the wheel centre, for the workpiece, cleaning and sensing electrodes or each may be supplied separately. Using spark erosion, the cleaning may be by successive bursts of pulsed discharges with the wheel connected either as cathode or anode. Working of a WC workpiece using a metal bonded diamond wheel and an aqueous solution of NaNO 3  is referred to.

Abstract: 1,216,329. Magnetic recording and playback. MOBIL OIL CORP. 12 Dec.; 1967, No. 56453/67. Heading G5R. [Also in Division H4] In the processing of seismic data (see Division H4) recorded magnetically as tracks (shown symbolically as traces 126 to 130) on drum 131, differential time-shifts are given to the playedback tracks by arranging play-back heads 141 to 145 on a flexible bar 146, and adjusting the bar ends so that the heads lie on one of a set of approximately hyperbolic curves. The head outputs are then summed at 151 to give a first summation signal, the heads are re-aligned on a second of the hyperbolic curves to give a second summation signal, and so on. After further processing of the summation signals, further timeshifts are introduced by a similarly mounted set of recording heads 141a to 145a. In a modification (Fig. 17, not shown) of the head mountings the flexible bars are eliminated and the heads are individually movable along guide slots by means of individual cam and camfollower devices. Additional differential timeshifts may be applied to the data by a set of playback heads arranged in a straight line (Fig. 13, not shown), the line making one of a plurality of acute angles with the width direction of the tracks.

Abstract: 587,431. Sights for guns on aircraft. BOULTON PAUL AIRCRAFT, Ltd., and SAYERS, W. H. Dec. 4, 1936, No. 33259. [Class 92 (ii)] [Also in Group XIX] Mechanism for computing azimuthal sighting corrections for "own speed" Vo and the "relative speed" VR of the target aircraft comprises a transverse lever 7 controlled by three members 4, 5, 6, sliding on parallel straight guide bars 1, 2, 3, the bars 2, 3 being displaced from the bar 1 by distances proportional to vacuum time of flight of bullet To and total time of flight TF( =To+TL) where TL is the time lag of the airretarded bullet. When the member 4 is displaced from a datum line O-O by a distance proportional to VO, and the member 5 to a distance proportional to VR, the member 6 registers a distance (Vo+VR)#{1+TL/TO#}-Vo which is a measure of the desired correction d. Fig. 7 shows to the left the mechanism with the bars 2, 3 adjusted for To, TF by rods r, s connected to the slides 49, 59 of a calculator as described in Specification 587,429. The slide 49 is operated by a screw 28 connected to the range-finder and the slide 59 conveys the gravity-drop or tangent elevation correction to the gun through cam o and follower 44, this correction being proportional to TF. The apparatus to the left of Fig. 7 shows the member 1 adjusted in relation to datum line O-O by the usual own speed crank 13. The member 5 is adjusted to suit the component of relative speed VR at right angles to the line of bearing of the target as determined by the apparatus described in Specification 587,430. It follows then that the member 6 will be positioned to give the correction d, the azimuthal angular equivalent of which d/R is obtained on a slotted link e by the sliding bar a operated by the member 6 and the pin g connected to bar 2 by an arm f.
