Filed: 1971-12-13
Abstract: 1377980 Extruding bitumen or sulphur OCCIDENTAL OEL GmbH 13 Dec 1971 [14 Dec 1970] 57715/71 Heading B5A Molten sulphur or bitumen material, is extruded as one or more strands each into a separate surrounding cooling medium stream, the velocity of which increases to subject the strand to tension in the direction in which it is conveyed by the medium, to be cut by a rotary cutter into shorter lengths which, after removal of coolant, are compression moulded into blocks a whilst in a plastic state. Each block is then enclosed in a protective foil, e.g. of polyethylene for bitumen. In the described embodiment, Fig. 1, molten bitumen from a vessel 1 is extruded, by a pump 2, as a strand 6a from the end of each of a plurality of steam heated nozzles 4, from which water coolant is also discharged around the strand 6a which it conveys along a transparent flexible conduit 6 terminating in a vertically downwardly directed outlet 8, a plurality whereof are circularly arranged around a multibladed rotary cutter 10 which cuts the pieces 6b from the strands. Each conduit 6 is of tapering configuration at 5 around the nozzle 4, at te outlet 8, and at intermediate locations 7 to increase the coolant velocity to convey and tension the strand 6a, and to centre it for the cutter 10. The cut pieces fall through a funnel 11 into a conduit 12 from which coolant separates from the bitumen, through conduit perforations 13 and via a surrounding jacket 14 to an outlet 15. The cut pieces 6b from the conduit 12 are received upon a vibrator conveyer 16 on which they are conveyed, through hot air drying at 17, optionally to a belt weigher 18 which incrementally delivers to the mould of an hydraulic press 19. Moulded blocks 20 are removed from the press 19 by a device 21 and delivered by a conveyer belt 22 into a device 23, for enclosure in the foil and from which a conveyer belt 24 delivers to a stacker device 24, loading on pallets which may be clad with shrink foil wrapper to form a unitary package.

Title: Data stores
IPC: G11C11/405
Filed: 1970-12-17
Abstract: 1316450 Data storage INTERNATIONAL BUSINESS MACHINES CORP 17 Dec 1970 [12 Jan 1970] 59901/70 Addition to 1316449 Heading G4C [Also in Division H3] A stored-charge matrix data store includes restore storage cells used for data regeneration, so that data can be regenerated without leaving the passive storage area of the system (which is acted upon by the means provided for selecting and energizing selected lines of the grid of word and bit lines). A bit cell, e.g. 10a, is addressed by applying a pulse R in all the decode units 30, 32 to charge the nodes A, B and the bitline capacitances C 0  ... C n , then applying a pulse SAR except in the units 30, 32 relating to the row and column containing the required cell. When present, the pulse SAR discharges the nodes A, B. The charged nodes enable (render conductive) the associated IGFETs 38, 40, 42. A bit can then be written by applying pulses # 1 , # 3  together, enabling IGFETs 16 (in the required cell) and 20 (in an auxiliary cell, e.g. 18a, respective to the matrix row) so that, provided a 0 is to be written, if the interelectrode capacitance C of IGFET 12 of the required cell is charged (storing 1) IGFETs 12, 16 shunt the bit-line capacitance C 0  to ground whereas if C stored 0, the interelectrode capacitance C in the auxiliary cell 18a is charged from the bit line via IGFET 20. However, if a 1 is to be written, the bit line is concurrently lowered at B/L and (due to enablement of IGFET 46 by # 3 ) overrides the effect of the bit in the required cell so that the capacitance C in the auxiliary cell is discharged via IGFET 20 to store 0. In either case, an R pulse is now applied, followed by concurrent pulses # 2 , # 3 , with or without lowering of B/L according as 0 or 1 is to be written respectively, # 2  enabling IGFETs 14, 22 in the required and auxiliary cells respectively, so that if a 1 is to be written, the 0 stored in the auxiliary cell disables IGFET 24 preventing the establishment of a shunt to ground for the bit-line, and C in the required cell is charged from Co via IGFET 14. On the other hand, if a 0 is to be written, the lowering of B/L discharges Co, overriding any effect of the auxiliary cell, and C in the required cell discharges via IGFET 14. Alternatively, the bit in the addressed cell can be read by applying # 1 , # 3  together, # 1  enabling IFGET 16 so that if C is storing 1 (charged) to enable IGFET 12 the bit-line capacitance Co discharges to earth producing a pulse via IGFET 46 (enabled by # 3 ) to a sense amplifier 44. A column (word) can be regenerated by applying, in turn, R, SAR, # 1 , R, SAR, # 2 . By enabling IGFETs 16, 20, # 1  transfers each bit in the column in complemented form into the corresponding auxiliary cell 18a ... 18b, and by enabling IGFETs 14, 22, # 2  transfers it back with recomplementing. The IGFETs 34, 36 may each be replaced by a plurality of IGFETs in parallel for the decoding function. Monolithic circuitry may be used.

Title: Imaging process
IPC: G03C5/10
Filed: 1970-12-21
Abstract: 1340207 Electro-photographic imaging XEROX CORP 21 Dec 1970 [2 Jan 1970] 60554/70 Heading G2H In the imaging process of Specification 1150381 using a manifold set comprising a structurably fracturable electrically photo-sensitive imaging layer sandwiched between donor and receiver sheets which are at least partially transparent, in which the set is imagewise exposed and separated while an electric field is applied so that the imaging layer fractures imagewise, the imagewise is effected by a contact reflex technique. A transparent drum for effecting the exposure is described. The process normally gives transparent images. Opaque images can be formed by either using sheets which can be rendered opaque after imaging (e.g. by evaporating off a liquid) or by transferring the portions of the imaging layer to an opaque receptor by a one- or two-step process. The manifold set may be uniformly exposed before the imagewise exposure.

Title: Generator frequency matcher apparatus using direct sampling
IPC: H02J3/42
Filed: 1968-12-30
Abstract: 1,246,980. Synchronising systems. WESTINGHOUSE ELECTRIC CORP. 30 Dec., 1968 [2 Jan., 1968], No. 61582/68. Heading H2H. A frequency matching system such as may be used when coupling an incoming generator on to a supply bus-bar comprises means for providing a first square wave signal of a first frequencysay the bus-bar frequency-and a second square wave signal of a second frequency-the frequency of the incoming generator-the two signals being applied to a circuit together with a signal representing the phase difference between the first and second signals such that the circuit selectively produces one of two output signals which are effective either to raise or lower the frequency of one signal relatively to the other so as to match the frequency of the two signals. The voltage of a bus-bar is applied to a clipping circuit so as to produce a square waveform at the frequency of the bus-bar, the square waveform being applied to a pulse shaper 251 and to an AND circuit 254, the output of the pulse shaper 251 being applied as one input to a second AND circuit 253. The voltage of the incoming generator is treated in a similar manner and connected to a pulse shaper 252 and to the AND circuits in a complementary mode. Simultaneously a triangular waveform representing the difference in phase between the bus-bar and generator voltages is applied to a level detector 255 and thence, by way of a pulse shaper 257 to two NOR circuits 261, 262. The outputs of the AND circuits 253, 254 are used to SET and RESET a bi-stable circuit 265, the outputs from this latter circuit forming the other inputs to NOR circuits 261, 262. When the generator frequency is below the bus-bar frequency the apparatus is effective to cause NOR circuit 261 to produce an output pulse which is stretched by unit 263, the resulting pulse on line 264 being used to step up the generator frequency in increments until frequency matching is obtained. Should the generator frequency be higher than the bus-bar frequency, NOR circuit 262 produces an output pulse thereby to lower the generator frequency. When the time interval between successive pulse outputs of shaper 257 is small, as would be the case when the difference input signal to the detector 255 is small, a timer 270 becomes effective to produce an unneeded raise pulse on line 264. The signal input to detector 255 is obtained by detecting when the phase difference voltage crosses a fixed voltage level (corresponding to 50 degrees) while changing in a negative direction. In a second embodiment the level detecting element is not used, the circuit then including phase shifting means, inverter means and at least four AND circuits. All the elements in the block diagram of Fig. 4 comprise a plurality of transistors.

Abstract: 633,978. Stitch separating. BRITISH UNITED SHOE MACHINERY CO., Ltd., and BRAY, W. N. Oct. 24, 1947, No. 28424. [Class 17 (i)] [Also in Group XXXVII] In a machine in which an irregularly curved workpiece is fed past an operating position by engaging the work margin and in which the edge is kept normal to the tool by the operator, means are provided to assist the operator, by increasing or decreasing the speed of the work feed as may be required and by giving audible warning if the work edge departs from correct relationship to the tool. The invention is described as applied to the stitch-separating machine described in Specification 174,164, [Class 17 (i)], the tool 13, presser foot 11, table 15 and block 19 corresponding respectively to parts described in that Specification. A bracket 21 fixed to a box of the work table has arms 27 pivoted on it which carry a block 29. A pivot pin 35 passing through the block 29 has at the top a gauge plate 37 (Fig. 4) the arms 39, 41 of which are urged to underlie the presser feet by springs and at the bottom a metal block 47 (Fig. 3). to which a plate 49 is fixed with insulation 51 interposed. Lugs 53, 55 are fixed to but insulated from the block 29 and have adjustable contact screws 63, 65 (Fig. 4). The screws 63, 65 and the plate 49 are connected to terminals on a block 71 so that when the plate is central the electric feed motor runs at an intermediate speed and when contact is made with the screws 63, 65 the speed is increased and decreased respectively, this speed alteration being clearly audible. In operation, the shoe is presented to the tool as in the prior Specification and the gauges 39, 41 engage the edge of the outsole. While both presser feet engage the crease and the shoe edge is normal to the tool, the plate 49 is central and the feed motor runs at normal speed but, as soon as the sole assumes an angle to the desired direction of feed, one gauge arm will be displaced and the control springs will move the plate 49 to keep both arms in contact with the outsole and contact will be made with one contact screw thus altering the feed motor speed. If definite fixed speed alterations are not suitable arrangements can be made to make the alteration of speed proportional to the displacement of the plate 49.

Abstract: 1281604 Differential thermal analysis EI DU PONT DE NEMOURS & CO 10 Oct 1969 [11 Oct 1968] 49976/69 Heading G1N The output signal from a transducer is augmented with the first differential to compensate for the lag between the actual change in the variable and the response from the transducer. As applied to  differential thermal analysis, Fig. 3b, the difference in temperature between a sample and a reference member subjected to a heating programme is measured by thermocouples 17, 18. The output signal is fed through an amplifier 1a to a first terminal A and via a differentiating circuit 20, 21, 22 to a second terminal B. The gains of the latter is adjusted so that the signal voltage between terminals AB represents the actual temperature difference between the sample and reference numbers, having compensated for the time lag in the response from the thermocouples. This signal may be used to differentially control the heating source to eliminate the temperature difference.
