Title: Improvements in or relating to data processors
IPC: G06F13/12
Filed: 1963-11-07
Abstract: 1,066,858. Digital data processing apparatus. HONEYWELL Inc. Nov. 7, 1963 [Nov. 7, 1962], No. 44031/63. Heading G4A. A data processing system comprising a programmed data processor operating in conjunction with peripheral equipment which requires a finite time to become operative, during which time processor orders can be performed, has means for generating one or more inhibiting signals denoting the progress of the peripheral equipment to the operative state, which signals are effective to suppress the selection by the processor of some or all of the orders. The execution of certain lengthy orders, which might interfere with the operation of the peripheral equipment, can thus be prevented. The processor described includes a magnetic core sequencer 10 as disclosed in Specification 962,095 and comprising saturable cores SC-1 to SC-7 the state of which can be controlled from a suppression register 12 consisting of a plurality of flip-flops SU-1, SU-2 &c., whose states are controlled by signals derived at 14 from the function digits of the order words. Associated with the processor is peripheral equipment in the form of a card reader 16. When a card read operation is called for, sequencer core SC-1 sets a flip-flop 18 to provide an output signal at 30 which sets suppression flip-flop SU-1 causing cores SC-1, SC-2 to be saturated via windings 33, 34, thereby proventing the selection of orders requiring control signals from either of these cores. The output 30 also conditions a gate 36 so that when a " clutch " signal is received from the card reader, indicating that a card can be clutched, a flip-flop 20 is set to provide " clutch card now " signal to initiate movement of the next card. After a time interval of 13 ms. (see Fig. 2, not shown) the card reader provides an " early warning" signal on a lead 24, thereby setting suppression flip-flop SU-2 to saturate cores SC-3, SC-4, preventing the execution of orders requiring these cores, for instance possible lengthy orders such as " multiply." After a further time interval of 18 ms. a " ready to receive " signal on a lead 26 causes further cores to be saturated. The initiation of an unusually long order causes a flip-flop IS-1 to IS-3 to be set and if the order has not been completed when a " first card row " signal produced by the card reader 16 on a lead 40 is received, a gate 22 is opened to provide a " programme check " signal which can indicate an error or stop the data processor. When a "last card row " signal is provided by the card reader on a line 42, flip-flops 18, 20 and any set suppression flip-flops SU-1 &c., are reset. The invention is applicable to other forms of peripheral equiqment such as a printer of tape unit.

Title: Snap-action electric relay
IPC: H01H43/30
Filed: 1975-10-27
Abstract: 1525287 Snap-action thermal relay DANFOSS AS 27 Oct 1975 [28 Oct 1974] 44091/75 Heading H1N In a thermal relay the moving contact arm 9, is moved into engagement with the fixed contact arm 12 by a snap-action spring 20 actuated by a member 19 which moves in the opposite direction to the moving contact and which carries a stop member 22 enabling movement of the moving contact to be blocked. The actuating member 19 is carried on bimetallic springs 17 and 18, the spring 17, which is heated by a heater 16, swinging the member 19 to the left when heated, thus moving the snap-action spring 20 over dead-centre and snapping the moving contact arm 9 to the right to engage the fixed contact arm 12, this movement being reversed upon cooling. The stop member 22 is a leafspring pivotally mounted at 32 in a slot 30 in the actuating member 19 and is swung from its inoperative position to the position shown in broken line by actuation of the relay 27 to attract armature 26. In this position a projection 23 on the stop member engages with a tongue 29 on the moving contact arm 9 and prevents it from moving under the action of the spring 20, a certain amount of elastic deformation taking place. As the stop member is carried by the actuating member it can be used to block the moving contact in either of its positions. It returns to the inoperative position when the armature 26 is released.

Title: Ion exchange polymer films containing n-monosubstituted sulphonamido groups
IPC: C08L27/18
Filed: 1974-10-14
Abstract: 1484611 Ion-exchange polymeric films E I DU PONT DE NEMOURS & CO 14 Oct 1974 [15 Oct 1973] 44513/74 Heading C3P [Also in Division C7] Ion-exchange films are formed from fluorinecontaining polymers having pendant sulphonyl groups attached to a carbon atom having at least one fluorine atom connected thereto, at least 40% of the sulphonyl groups on a first surface of the film and to a depth of at least 200  being in the form of N-mono-substituted sulphonamide groups or salts of such groups, such groups being derived from a primary amine, and most of the sulphonyl groups on a second surface of the film being either in ionic form or in the form of -SO 2 NH 2  groups. The polymers are prepared by reaction of a primary amine, e.g. methylamine, ethylamine, cyclohexylamine, ethylene diamine, 1,6-diaminohexane, triethylene tetramine, aniline or hydrazine, with a polymer containing sulphonyl halide groups, e.g. a copolymer of tetrafluoroethylene with perfluoro(3,6 - dioxa - 4 - methyl - 7 - octenesulphonyl fluoride), followed if desired by neutralization of the acidic -SO 2 NHR groups with a base. Remaining sulphonyl halide groups may be converted to sulphonamide, sulphonamide salt, sulphonic acid or sulphonate salt groups by appropriate reactions, e.g. hydrolysis. Conversion of the sulphonyl halide groups may be effected throughout the film or through only part of the depth thereof. In the former case, the film may be laminated to a film of a fluorinecontaining polymer having pendant sulphonyl groups in -SO 2 NH 2  form or in ionic form other than that of the first film. Films or laminates containing N-mono-substituted sulphonamide/ salt groups at one surface are suitable for use as an ion-exchange membrane separating the anode and cathode compartments of an electrolytic cell (see Division C7).

Title: Wire winding machine
IPC: B65H67/056
Filed: 1963-11-12
Abstract: 1,057,139. Continuous winding of wire. COMPAGNIE FRACAISE THOMSONHOUSTON. Nov. 12, 1963 [Nov. 13, 1962], No. 44626/63. Heading D1J. A wire winding device for continuously winding wire on one or other of a pair of adjacent spools comprises adjacent coaxial spindles 2, 2' 2' on which spools 5, 5' are mounted, each spindle being driven by a separate electric motor 3, 3' and includes a smooth curved member 7 which shrouds the adjacent flanges 6, 6' of the spools to facilitate transfer of the wire from one spool to the other. Traversing means for the wire includes a guide pulley T the path of traverse of which is determined by the action of fixed stop members C 1  C 2  and retractable stop members E 1  E 2  on a reversing switch I 2  associated with the traversing pulley T. As shown, for the left hand spool, stop members C 1  E 1  act on the reversing switch I 2  and cause the guide pulley to traverse over the length of that spool. When the spool is filled manual operation of a control switch (not shown) starts the motor 3' of the right hand spool 5', causes the retractable stop members to move to the position shown dotted and the guide pulley consequently moves into the region of the right hand spool 5', causing the wire to transfer over the member 7 to the spool 5'. After a few turns have been wound on that spool the control switch is manually turned to a further position which brings the retractable stop members E 1  E 2  into their operative position again and also causes a reversal of direction of traverse of the guide pulley T. This has the effect of winding a few superposed locking turns of wire on the turns initially laid on the spool 5'; furthermore when the stop member E 2  is reached for the first time a switch I 1  also associated with the traversing means is operated by the member E 2  to stop the motor 3 which causes the intervening wire between the spool to break. Alternatively a saw member may be brought into position to sever the wire which joins the two spools. Each unit comprising a spool, the spindle upon which it is mounted and the respective motor is pivotable about a horizontal axis A B or A' B' for doffing and replacement of the filled spool.

Abstract: 1,061,169. Shoots. I. DONNER. Jan. 31. 1966 [Nov. 3, 1964], No. 44839/64. Heading B8S. [Also in Division D1] A jet of compressed air is used to assist the passage of synthetic plastics buttons along a slide from a container to the stitching point of a button sewing machine. As shown, buttons pass in succession from a container down a first slide to a cylinder adapted to rotate one way or the other for presenting each button right side up to a second slide 5. The button is conveyed by the latter to a station 7 where it is rotated by a plunger 9 to align its holes with pins 10 on the end of a pivoted arm 11. The latter then transfers the button to clamping jaws 12 at the stitching point 8. Plunger 9 is raised after actuation to close a micro-switch 15, whereby an electric timer is energized to open a solenoid valve for a predetermined time interval. Compressed air thereby flows to a first nozzle so positioned as to free a button from said rotary cylinder, and also passes to a second nozzle 24 adapted to assist the button along slide 5.

Title: Improvements in or relating to refrigeration apparatus
Inventor: PEARSON STEPHEN FORBES
IPC: F25B5/04
Filed: 1960-12-31
Abstract: 1,015,321. Refrigeration. L. STERNE & CO. Ltd. Dec. 28, 1961 [Dec. 31, 1960], No. 44901/60. Heading F4H. In refrigeration apparatus including a main condenser 3, an expansion device 7, an auxiliary evaporator 8 and a main evaporator 13 connected in series, the auxiliary evaporator may be caused to function as a condenser while the main evaporator continues to function as an evaporator. The apparatus shown is for use in a refrigerated display cabinet in which the main evaporator is incorporated in the side wall of the cabinet and the auxiliary evaporator is located above the maximum level to which foodstuffs are loaded, air cooled by the auxiliary evaporator being deflected by plates to flow over the foodstuffs stored in the cabinet. In such apparatus, the auxiliary evaporator requires more frequent defrosting than the main evaporator, and such defrosting is effected while the auxiliary evaporator functions as a condenser. During normal operation, refrigerant is passed from a compressor 1 through a water evaporating coil 2, the fan-cooled finned condenser 3, a drier 5, heat exchanger 6, main expansion capillary 7, the evaporator 8, a solenoid valve 9, the evaporator 13, and a liquid refrigerant accumulator 14 and is returned to the compressor via the heat exchanger 6 and a liquid trap 15. For defrosting, the condenser cooling fan is stopped, valve 9 is closed and a valve 16 is opened by a timercontrolled electric circuit (Fig. 2, not shown). The condenser 3 is then by-passed, and refrigerant from the compressor flows direct via a coil 18 and evaporator 8 which both act as condensers), and then via a filter 8 and auxiliary expansion capillary 12 to the evaporator 13. The coil 18 prevents refreezing of the defrosted water dropping from the exterior of evaporator 8.

Inventor: CLARK LEONARD
IPC: C25D13/22
Filed: 1964-11-04
Abstract: In a process for the electro-deposition of a film-forming material upon a metallic article from an aqueous film-forming composition in which the film-forming material is rendered hydrophilic by the use of a water-soluble volatile base, the metallic article constitutes one electrode of the electrolytic cell, and the other electrode is formed by a plurality of conductive elements of which some only are enveloped in or surrounded by a semi-permeable membrane, the base liquid which passes through said semi-permeable membranes during electrolysis being withdrawn from the cell and the amount of base thus withdrawn being regulated by selectively switching some of the surrounded or non-surrounded conductive elements into or out of the electric circuit of the cell, such as to maintain the pH of the bath within a predetermined range in the neighbourhood of the article to be plated.  The membrane may take the form of a cylindrical porous ceramic pot having a closed base and the open end thereof extending above the liquid level in the cell, the liquid therein being removed by means of an inverted U-tube. Alternatively the membrane may be sealed to the electrode at both top and bottom, an outlet conduit being provided to convey liquid from the space with the membrane to outside the cell.  This conduit may be provided by use of a hollow electrode having perforations for the passage of liquid therethrough. The liquid level within the membrane is preferably maintained at substantially the same level as the liquid in the cell.
