Title: Improvements in and relating to synchronous motor control systems
IPC: H02P1/46
Filed: 1949-06-02
Abstract: 662,266. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. June 2, 1949. [June 11, 1948] No. 14845/49. Class 38 (iii). Relates to the control of a synchronous motor having armature 1a and field winding 1b. Actuation of push-button 8 closes an auxiliary relay 10, contacts 10c of which shortcircuit a portion of a resistor 17. A main contactor 2 is energised through contacts 10b, 10d, the armature winding of the motor being connected to a three-phase supply. Maintaining circuits are completed for the relays 2, 10, and a voltage coil 15b is strongly energised so that contacts 15c are closed. A closing-coil 12b of a field relay. 12 is energised through contacts 26, a drop-out coil 12a being connected across discharge resistor 11. An alternating- current of slip frequency is induced in the field winding 1b, the coil 12a being supplied with half-wave current through rectifier 13. A relay 14 is energised through contacts 12e and picks up immediately to interrupt the circuit of the coil 12b, the relay 12 remains held in, however, due to the continued energisation of coil 12a. When the motor has accelerated to a speed approaching that of synchronism the coil 12a becomes de-energised, contacts 12e open to de-energise relay 14 which begins to time out, and contacts 12d close to energise field contactor 6 so connecting the field winding 16 across the direct-current source 7, 7a. The field contactor remains energised through contacts 15c after the relay 14 has timed out. The relay 14 prevents premature operation of protective relay 15 due to the unstable conditions obtaining first after synchronisation. At the end of the timing-out period of relay 14 the relay 10 is de-energised to insert the whole of resistance 17 in series with voltage coil 15b. If the motor pulls out of synchronism the phase angle between the currents in coils 15a, 15b, becomes sufficient to allow opening of contacts 15c and de-energisation of field contactor 6. The motor armature and field windings are then disconnected from their sources of supply. Automatic re-synchronising operation may be provided by means of loop connectors 18, 19.

Title: Improvements in or relating to the generation and synthesis of musical sounds
IPC: G10H1/08
Filed: 1926-06-15
Abstract: 271,259. Zouckermann, A. June, 15, 1926. Electrically vibrated instruments.-A key-board instrument in which alternating currents are generated and combined to sound a loud speaker comprises as many small alternators as scale notes required, each consisting of a toothed disc 8<1>. Fig. 1, and as many coils 9 (with magnetized cores) as harmonics (including the fundamental) required. Each horizontal row of coils 9, Fig. 2 therefore corresponds to one toothed disc. The first vertical row of coils sounds the fundamentals; the second - - sixth vertical rows sound the first - - fifth harmonics of other fundamentals. The electric vibrations are produced with small intensity and amplified after combination, to improve the purity of the sound. The coils of the fundamentals, and of each order of the harmonics, are respectively connected in series to the primaries 10 of corresponding transformers. Connections from the secondary windings 11 to the amplifier 29 and loud-speaker 32 are made through resistances 14, 15 and tap contacts 28, so that the relative strengths of the harmonics, and consequently the timbre of the resultant sound, may be regulated. The coils 9 are normally shortcircuited, but depression of a key 17 permits current to flow simultaneously from the fundamental coil 18 and the harmonics coils 21, 24 - - 27.

Title: Improvements in or relating to the purification of polyacrylonitrile filaments and films
IPC: D05B1/20
Filed: 1953-06-01
Abstract: In the production of filaments or films by coagulation of an aqueous polyvalent metal salt-containing solution of a polymer containing at least 85 per cent of polyacrylonitrile, the filament or film, before drying, is immersed in an aqueous solution of a water-soluble sequestering agent for the polyvalent metal ions in the salt contained in the coagulated filament or film, until the salt content is reduced to a negligible value, and the filament or film is then dried.  The coagulation of the filaments or films may be effected by extrusion of the solution into water, acid or dilute brine, followed by cold or hot stretching or both, with following or intervening treatment with water or other coagulant to reduce the salt content to 2-5 per cent.  After the final wet stretching treatment, and before drying, the filaments or films are passed through an aqueous solution of the sequestering agent. The preferred agents include the alkali metal salts of ethylene diamine tetra-acetic acid and of polyphosphoric acids.  The metal ions which may be removed from the filaments include zinc, calcium, magnesium, tin, aluminium, antimony, arsenic and bismuth. In the example a solution consisting of 7 per cent by weight of polyacrylonitrile, 31.6 of zinc chloride, 23.2 of calcium chloride and 38.2 of water is extruded into water at 15 DEG C. to form a tow of filaments which is cold-stretched in air, stretched in wet steam, washed for 10 seconds in water, and passed through a 10 per cent solution in water at pH 8 of the tetrasodium salt of ethylene diamine tetra-acetic acid for one minute.  The treated fibres are suitable for use in making woven or knitted goods.

Title: A pattern reading system
Inventor: WATANABE SADAKAZU
IPC: G06V10/20
Filed: 1970-03-31
Abstract: 1,263,667. Pattern recognition. TOKYO SHIBAURA ELECTRIC CO. Ltd. 31 March, 1970 [31 March, 1969], No. 15265/70. Heading G4R. A pattern reading system scans the pattern photo-electrically to produce video signals which are quantized in two quantizers using respective threshold levels, the first quantizer substantially eliminating signals corresponding to stains on the pattern record carrier but may introduce cuts in the pattern, and the second quantizer substantially not introducing cuts but possibly leaving stain signals, a circuit arrangement responding to the outputs of both quantizers to substantially fill up the cuts in the output of the first quantizer but substantially eliminate the stain signals. The quantizer outputs are registered in respective matrices of bi-stables. An AND gate and OR gate are provided for each pair of corresponding bi-stables (one bi-stable from each matrix). The OR gate receives the 1 output of the corresponding bi-stable of the matrix for the first quantizer and the outputs of the AND gates associated with the four nearestneighbour matrix positions. The AND gate receives the output of the OR gate and the 1 output of the corresponding bi-stable of the matrix for the second quantizer, and feeds a respective bi-stable in a third matrix. More than the four nearest-neighbour positions may be involved e.g. diagonally-displaced positions. The first and second matrices may be replaced with storage for one row or column of the matrix subdivision of the pattern only. Each quantizer retains the background level at the junction of a diode and capacitor, the diode being fed with the input, and uses a differential amplifier to obtain the difference of the input and this background level. The difference is quantized using a Schmitt trigger.
