Title: Improvements in the control of electric switches
IPC: H02J13/00
Filed: 1922-10-06
Abstract: 213,941. British Thomson-Houston Co., Ltd., and Fitzgerald, A. S. Oct. 6, 1922. Protective arrangements.-In order to prevent the operation of overload or other protective gear by the transient heavy capacity, magnetizing &c. currents occurring during the switching on or off of the protected circuit, an auxiliary direct or alternating electromotive is arranged to be impressed upon a winding during the switching operation to restrain or render less sensitive the protective means. The impressed auxiliary electromotive force produces a flux the effect of which counteracts the action of the operating flux of the protective apparatus. The invention is described with reference to protective arrangements employing biassing transformers of the type described in Specification 193,434. As shown in Fig. 1 the transformer 1 supplied by bus-bars 2 through a crcuit breaker 3 has a circulating current protective system consisting of series transformers 4, 4 which supply current to the restraining winding 5 of a biassing transformer. The primary winding 6 of this transformer is connected across equipotential points in the system. The secondary winding 7 instead of being connected direct to a relay, supplies the primary 8 of a second biassing transformer, the secondary winding of which energizes a relay 9 in the circuit of the circuit-breaker trip coil 13. The restraining winding 11 of this second transformer is arranged to be energized from an auxiliary direct current source during the motion of the operating rod of the circuit-breaker 3, its circuit being broken by one or other of the switches 12 when the circuit-breaker 3 is in the full on or full off positions. Thus during the movement of the circuit-breaker 3 the winding 11 exerts a restraining effect on the protective arrangement preventing operation of the circuitbreaker by transient magnetizing currents. A permanent restraint of the protective means may be imposed by the winding 11 when connected across the auxiliary source in series with a. resistance 22 by means of a switch 21. The two biassing transformers are combined into a single structure in other modifications, and when applied to a system employing a remotely-controlled circuit-breaker the circuit of winding 11 is arranged to be closed at contacts of the manually-operated control switch.

Title: A method and machine for making tagged laces
IPC: A43D98/00
Filed: 1926-10-29
Abstract: 260,611. Bracht, F., and Sperber, E. Oct. 29, 1925, [Convention date]. Laces.-Pieces of celluloid, each corresponding in length to two tags, are fed mechanically to the plaiting point of a plaiting machine and are worked into the web in a continuous operation during the plaiting. Acetone or other solvent is applied to the points in the lace at which the pieces are embedded, pressure is applied by dies, and the laces are then cut into length. Fig. 1 shows a machine for making two laces simultaneously, each of the sets of bobbins revolving in known manner and feeding the threads 9 to a plaiting point in a plaiting iron 8 to form the laces. A strip 48 of celluloid is fed forward intermittently by rollers 49 to each plaiting point and is cut by a blade 46 into' equal pieces which are fed by steps to the plaiting irons 8 and worked into the lace during plaiting, the opening in the plaiting iron 8 being narrowed by an eccentric 31 and rod 32 during this period. The uppermost piece of celluloid for the time being is gripped by a holding device 61 to prevent it slipping back or passing prematurely to the plaiting point. The laces are fed forwards by feed roller mechanism 6 over guide rolls 63 to an acetone apparatus 16 where acetone or other celluloid solvent is brought into contact with the parts of the laces containing the tag pieces by means of nozzles arranged in lateral guides and through which the acetone is forced by a piston moving intermittently under the action of an eccentric 25 and rod 26 in a receptacle containing the solvent. The lace is passed to pressure dies 24 which are pressed together at regular intervals by an eccentric 21 through rods 22, 23 to consolidate the tag. These dies may be heated, for example, by electricity. The cutting of the work into individual laces is effected by an eccentric mounted on a vertical shaft driven by worm gear from a shaft 20 which makes one revolution during the production of a single lace and controls the movements of all the tools. This eccentric operates a blade to sever the lace tag, the work being held meanwhile by a lever 35. The arms carrying the guide rollers 63, the plaiting iron 8, the acetone apparatus 16 and pressing tools 24 are adjustable vertically and horizontally on a rod 13 carried by the end supports of the machine. The drive to the shaft 20 is variable and the eccentrics 21, 25, 31 operating the tools are adjustable so that laces of different lengths may be produced.

Title: Improvements in or relating to the removal of moisture from solid fuels
IPC: C10G1/00
Filed: 1958-08-27
Abstract: 844,556. Treating solid fuels. GLINKA, C. Aug. 27, 1958, No. 27502/58. Classes 50 and 55 (1) In a thermal treatment of wet solid fuels, e.g. oil shale or peat, containing substances convertible to bitumen wherein the wet fuel is heated in admixture with a treating oil, the treatment is carried out in two stages, a first stage employing a pressure above 12 atm. and a temperature which at the pressure employed is above the boiling point of water but below that of the treating oil, e.g. between 250‹ and 350‹ C. at a pressure of 30 atm., and a second stage employing the same pressure but a temperature above 400‹ C. whereby vaporous products are obtained from the substances convertible to bitumen. Peat may be first heated under pressure in water to a temperature at which the colloidally bound water contained in the peat is released, the thus treated peat being admixed with treating oil whilst maintaining the pressure and temperature of the preliminary treatment and then passed to the first stage of the twostage thermal treatment. A suitable treating oil is a heavy oil fraction boiling between 300‹ and 400‹ C. Plant for carrying out the process comprises two tubular treatment zones 1 and 15 wherein the first and second stages of the thermal treatment are effected respectively and through which the treating oil is circulated by pumps 3 and 13. Comminuted wet fuel to be treated is fed from a hopper 27 into a tubular ring connected to the zone 1 by pipes 24 and 25 and through which a part stream of the treating oil circulated by the pump 3 passes. The ascending stream of treating oil carries the fuel upwardly, steam is released at 5 and the treating oil and dried fuel pass to a separator 7. Treating oil leaves the separator through line 9 and is partly returned to the pump 3 for recirculation and partly enters a heater 12 and is then pumped by pump 13 to entrain dried fuel leaving the separator 7 by line 28. Vaporous products are released at 17 from the treatment zone 15 and the treating oil and residual fuel are separated in a separator 19. The residual fuel from the separator 19 passes through a trap 29 into a chamber 30 where reduction in pressure releases further vaporous products and any entrained treating oil which leave by air outlet 31, solid residue falls on to a conveyer and is removed. Treating oil from the separator 19 returns to the pump 3 by line 20.

Filed: 1973-06-12
Abstract: 1440392 Fiat cables; component assemblies WESTERN ELECTRIC CO Inc 12 June 1973 [12 June 1972] 27821/73 Headings H1A and H1R In a flat cable 30, or a printed circuit assembly 30, electrical conductors 34, 36 are disposed in a flat array of transposed pairs, the conductors of each pair being laterally spaced apart throughout the intervals between cross-over points 37, and the interval dimensions between crossover points differing from pair to pair in a binary relationship, thereby providing a series of different patterns of periodicities of the crossings, which patterns are identified by reference letters A, B, C, &c. in the drawings, with the conductors arranged in the array in such a manner that all adjacent pairs have different patterns of periodicities, and also that all corresponding pairs at equal distances from a centreline of the array have different patterns of periodicities. A result of this arrangement is that crosstalk becomes minimized, not only between conductor pairs within one array, but also between any two pairs situated in separate arrays, which two pairs may become juxtaposed one above another when a second array is stacked in an aligned layer above a first array, where the second array has a pattern of periodicities similar to that of the first array but reversed, i.e. where two cables of similar patterns of periodicities are stacked one upon the other, the upper one being inverted relatively to the lower one. Stacks of a plurality of such arrays may be composed of successively alternating layers of first array and second array natures. Fig. 11 indicates the pattern arrangements in an aligned stack incorporating arrays of one embodiment, in which a central track space is occupied by a single conductor alone, identified by reference O, not used for active signals, and there are five varieties of pairs A, B, C, D and E. In Fig. 12, the same array embodiment is shown displaced in misalignment by one track pitch without incurring crosstalk. In other embodiments, Figs. 13, 14, (not shown), misalignments of two track pitches and three track pitches may be tolerated, when the arrays contain singleconductor tracks O in the central two or three locations respectively. The cable or circuit board may be composed of flat conductors 44, 46, Fig. 3, on opposite sides of a dielectric strip 41, with covering layers of dielectric tape 48 secured by a dielectric adhesive 49. Alternatively, the conductors of a flat cable may consist of insulated wires.
