Title: Improvements in and relating to electric apparatus
Inventor: HERZOG MAX
IPC: H01F27/14
Filed: 1961-11-09
Abstract: 920,051. Transformers. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Nov. 9, 1961, No. 40185/61. Class 38 (2). Liquid-immersed electric apparatus such as a transformer or capacitor operated at high voltage is contained in a closed vessel 1 which connects with a first space 3 (which may be in the vessel) containing inert gas 5 such as nitrogen supplied through a valve 9 from a reservoir 10 and the first space is connected by a gas flow passage with the top of a second closed space 13, the lower part of which contains liquid and connects through a liquid flow passage 15 to a third space 12 which is open to the air. A device 18 which senses the liquid level in either the second or third space controls the valve 9. In the Figure the second and third spaces are parts of the single vessel 11 separated by the member 14. The expansible containers 6 allow a greater variation in gas volume in the first space than would otherwise be possible. The member 8 is a de-humidifier containing for example silicon gel. If the pressure in the first space rises sufficiently gas passes from the second to the third space escaping to the air and the baffle 22 prevents the rise in gas bubbles from disturbing the float 21 of the device 18. If the pressure falls the float 21 also falls and device 18 opens the valve 9 allowing gas to flow from the reservoir to the first closed space. A window or indicating device may be fitted to the vessel 11 so that the liquid level may be readily observed.

Title: Convertible automatic to non-automatic coupling for rail vehicles
IPC: B61G5/04
Filed: 1958-12-15
Abstract: 899,772. Transitional type couplings. HILGER, O., and BUSCH, W., [trading as BERGISHE STAHL-INDUSTRIE REMSCHEID]. Dec. 15, 1958 [Dec. 21, 1957], No. 40348/58. Class 103(5). A transitional type coupling which transmits full draught load but is protected by side buffers from most of the buffing load, comprises an automatic head 11, a link 13 pivoted to a pin 14 in the head and connecting the head to a draw-hook 15, an angled member 19 on each side of the hook pivoted to a pin 20 in the hook, pre-loaded compression springs 17 having abutments 16, 16a at each end universally jointed to the pin 14 and the members 19 respectively, and pin and slot connected telescopic members 24, 25 joining the abutments. The head may be lowered and hung by its link 13 in an out of use position by lifting the head and disengaging the link 13 from the hook, the members 19 pivoting freely forwards about the pin 20 to allow this to be done, Fig. 4 (not shown). In the coupling position, the head is supported by co-operating abutments 33, 34 on the eye and head respectively and by the springs 17, which springs .since they are universally mounted on the pivotable members 19 also allow limited movement of the head in a horizontal plane, and the members 19 are forced against abutments 26 on a forked member 27 having limbs on either side pivoted to the pin 20, the bridge part 29 of the member 27 having an adjustable screw 30 which abuts the draw rod 28 to fix the positions of the abutments 26 and also permits the head to be raised or lowered slightly with respect to the rails. Instead of the described link members, a triangular link member may be pivoted at its upper corner to the hook and its its forward lower corner to the spring, its third corner abutting the hook shaft to limit the motion of the triangular link. It is also possible to arrange the springs above the longitudinal axis of the coupling, the rear portions of the springs being pivoted directly to the hook whilst the forward portions are linked to the coupler head.

Filed: 1960-11-28
Abstract: 919,811. Laminates; fireproofing; paper. SWIFT & CO. Nov. 28, 1960 [Feb. 15, 1960], No. 40838/60. Classes 96 and 140. Webs of fibrous cellulosic materials are rendered fire- and flameproof by depositing on the web a composition including a homogeneous mixture of at least one halogenated fatty acid derivative which is liquid at ambient temperatures, an adhesive which is insoluble in or immiscible with the derivative, and a waterinsoluble salt or oxide of antimony, arsenic, bismuth or tin. By " fatty acid derivatives " is meant esters, alcohols, amides and ethers derived from aliphatic monocarboxylic acids having from 10 to 30 carbon atoms. The composition is preferably deposited in the form of a thin film. The heated web may be pressed against a backing material so as to cause the web and the backing material to become bonded and the halogenated fatty acid derivative to migrate and impregnate the backing material. The cellulosic material may be paper, fabric, or wood, especially heavyweight paper as employed in building trades, although other paper stock, jute, woodpulp, cotton &c., may be bonded to other material. Veneer board comprising several thin layers of wood may be bonded by the flameproofing composition. Cellulosic materials such as paper, wood, wallboard and cotton fabric may be adhered to webs of the same type of material or to metals, plastics and non-cellulosic fibres. In examples, kraft paper was laminated with other sheets of paper or aluminium foil, with or without a glass fibre scrim. The adhesive component of the mixture may be any known adhesive such as glue, rosin, starch, soybean flour, casein adhesives, synthetic materials such as polyvinyl alcohol, polyvinyl acetate, and latex. The halogenated material may be a mono-, di- or polyhydric aliphatic alcohol ester of a halobenated fatty acid of 10-30 carbon atoms, such as brominated soybean, sesame, rapeseed, linseed, safflower, menhaden, cottonseed- or fish oil, or lard or tallow. Halogenated animal and vegetable triglycerides, and halogen substituted higher fatty acid esters of aliphatic glycols and tetritols, pentitols and hexitols may be employed. The metal oxide or salt may be an oxide or sulphide of arsenic, antimony, bismuth or tin, antimony potassium tartrate, lead antimonate, lead arsenate.

Title: Improvements in drying natural gas
IPC: C10G5/02
Filed: 1960-11-29
Abstract: 912,939. Drying natural gas. UNION CARBIDE CORPORATION. Nov. 29, 1960 [Nov. 30, 1959], No. 40945/60. Class 34 (1). A method of drying a moisture-containing natural gas stream comprises passing the stream through a bed of zeolitic molecular sieve material having pore sizes less than 4.7 Angstron units. A stream of natural gas is dried by passages under pressure from a compressor 11 through a bed 14 of crystalline zeolitic molecular sieve material having pore sizes less than 4.7 Angstrom units while a minor portion of the stream is diverted through a conduit 17, heated to between 400-500‹ F. in a passageway 18 to regenerate a second zeolitic sieve bed 22 which has been previously utilized, the moisture-laden gas being cooled in a passageway 26, condensing water in a separator 28 and mixed with the main gas stream in a conduit 31. The action is reversible by periodically switching the flows through the beds. The zeolitic material pores are sufficiently small to exclude aliphatic hydrocarbons of molecular size larger than propane. The gas may be continued to be dried in the bed until the dent point rises to certain limits, e.g. - 15‹ F. or - 80‹ F., the cooled gases being mixed with the dried to effect a composite water content within specified limits, e.g. 7 pounds per million standard cubic feet and the molecular material undergoing regeneration may be dried to less than 3% of water. Specifications 777,232, 777,233, 841,812, 868,846, 909,265, 909,266 and 912,936 are referred to.

Title: Starters for internal combustion engines
IPC: H02H7/093
Filed: 1971-09-09
Abstract: 1350276 Starting internal combustion engines ROBERT BOSCH GmbH 9 Sept 1971 [10 Sept 1970] 42057/71 Heading H2H [Also in Division H3] A circuit for protecting the starter motor 19 of an internal combustion engine comprises a relay 188, 20 for de-energizing the starter motor when the engine speed exceeds a lower limit, a pulse generator 11 the frequency of which increases with the engine speed, a first monostable multivibrator 12, a second monostable multivibrator 14, a delay circuit 18 and an "AND" gate 15 to which the multivibrator outputs are connected, the output of the AND gate being connected to the delay circuit so that when the output pulses of the second multivibrator overlap the output pulses of the first multivibrator the relay contacts 20 are opened for a predetermined time. The pulse generator comprises a magnet 110 attached to the crank-shaft and co-operating with a coil 111 but alternatively a photo-electric generator or the primary winding of an ignition coil may be used. The frequency of the output pulses of the multivibrator 12 increases as the speed increases and an inverter 13 ensures that the output pulses of the multivibrator 14 immediately follow the output pulses of the multivibrator 12. The speed of the engine and therefore the starter motor increases until the width of the output pulses of the multivibrator 14 exceeds the separation of the output pulses of the multivibrator 12, the consequential pulse overlap being detected by the AND gate 15 which causes a multivibrator 16 to produce output pulses of predetermined width and independent of the speed of the motor in excess of the limit. The pulses are fed through an "OR" gate comprising diodes 183, 184 to the delay circuit 18 constructed as a Miller integrator which generates a sawtooth output voltage to hold the contacts 20 open for the ten second duration of the sawtooth. This time duration enables the engine to come to a halt before the starter motor can again be actuated by closure of a switch 21. A circuit 17 prevents a second attempt being made to start the engine before the engine has come to rest after the first attempt. A differentiating circuit 171, 174, 175 provides a negative voltage spike when the motor 19 is switched off and a transistor 170 coupled as a Miller integrator supplies a negative sawtooth voltage to the delay circuit 18 thus holding the contacts 20 open until the engine has come to rest. The relay may be replaced by a thyristor.

Abstract: 1,269,538. Checking machining accuracy. BRITISH AIRCRAFT CORP. Ltd. 18 Aug., 1970 [23 Aug., 1969], No. 42137/69. Heading B3B. [Also in Division G3] To check the accuracy of machining operations carried out by a numerically controlled machine tool, a separate reference piece 6 is fixed with respect to the workpiece 5, and cuts are made upon it, Fig. 2 (not shown), which can be checked for accuracy by measurement, Fig. 3 (not shown). The accuracy may be checked before and after a machining sequence on the workpiece, making shallow reference cuts before machining the workpiece, and deeper ones, preferably right through the reference piece, afterward. Comparison of such reference cuts enables checking for the presence of machining error. A master reference piece may be made by machining away the base (20), Fig. 3 (not shown), of a correct reference piece, until the holes come right through, and may be used to check any other reference piece visually by locating both pieces via holes (16), Fig. 2 (not shown), which also serve to locate the testpiece, on pins 4. A wire and lead seal 9, 10 may be used. The control programme is on punched or magnetic tape, divided into sequences, between which the tool 7 comes to rest at a datum print 8. The work-table 1 carries a fixture 2 supporting the workpieee 5 and reference piece 6. Reference pieces are supplied in standard sizes, made in Al alloy, and carry reference marks to ensure their correct positioning with respect to the workpiece. In Fig. 2 (not shown) are displayed typical test cuts in a reference piece, as made by a slot drill (11), an end mill (12), form tools (13). A fillet radius (15) may also be tested. Fig. 3 (not shown) displays a tapered gauge (17), region (18) indicating allowed tolerance, tapered probe (21) enabling the co-ordinates of the hole to be obtained.
