Abstract: 1,134,666. Air classifier. CHRISTIAN PFEIFFER. 25 May, 1966, [26 May, 1965], No. 23358/66. Headings B2H and B2P. In a classifier in which material is classified by means of a circulating air current, the material is scattered into the classifying space by means of a rotary spreader 10 comprising coaxially arranged and spaced apart discs providing between them a passage for classifying air. As shown, the spreader 10 is mounted within an inner casing 2, 3 on a rotary shaft 15 which also carries a fan 6 which causes the air to flow upwardly through the inner casing and into the space between the inner casing and an outer casing 1, 12. The material to be classified is fed through a channel 8 which is divided by a por§us plate along its length into an upward compartment into which the material is introduced and into a lower compartment to which air is fed and passes through the porous plate into the upper compartment to entrain the material. Alternatively, Figs. 2 and 4 (not shown), the material is fed through a centrally arranged vertical downtube (9). Cold air or warm air may be supplied to the underside of the spreader via a pipe 11. A centrifugal counter-vane system is provided at 7. The spreader may comprise straight or conical annular discs (24 or 25), Figs. 5 to 7 (not. shown), depending from a hub 26 and secured to one another by means of straight (Fig. 8 not shown) or curved (Fig. 9 not shown), adjustable guide-vanes 23, 30 or 31. The discs are arranged in stepwise fashion with the small disc at the top., In operation, the material to be classified is scattered by the spreader 10 and acted upon by air passing upwardly between and around the discs. The light material is entrained upwardly and passes into the space between the inner and outer casings to be discharged via the funnel 12. The coarse materials falls through the inner funnel 3. The air is re-circulated into the inner casing via louvres 4. A fraction of air corresponding to the amount of cool or warm air introduced continuously through the pipe 11  may be removed via a pipe 14. Alternatively, that fraction of air is extracted wholly or partially through the funnel 12. The countervane system 7 provides braking of the upward air current and at the same time allows only the air and the fine material to pass through it. The fan 6 .may be rotated at a speed different from that of the spreader 10 and the vane system 7. In other embodiments, Figs. 1 and 2 (not shown) no additional air is provided and the pipes 11 and 14 are dispensed with.

Title: Pattern identification system
IPC: G06V10/75
Filed: 1971-04-19
Abstract: 1344172 Pattern recognition systems TOKYO SHIBAURA DENKI KK 19 April 1971 [7 March 1970] 23451/71 Heading G4R In a pattern recognition system signals are derived representative of the distances between the input pattern and reference patterns. The distance signals are modified by correction signals to compensate for deformities in the pattern. The smallest modified distance signal indicates the reference pattern most nearly matching the input pattern. The system employs M circuits, each as indicated in Fig. 2, for the recognition of M patterns. Each circuit includes a first section comprising operational amplifiers 14, 18 and M further sections comprising amplifiers 22, 27 ... As shown M = 2. Signals Xi (i=1-N) representing the pattern are fed to N squaring circuits 11, the resulting signals being summed and the sum passing to operational amplifier 34. Signals Xi are also fed to weighting resistors 15 which feed amplifier 18. Amplifier 18 also receives a reference signal via resistor 16. The output of amplifier 18 is passed to amplifier 34. If there were no other input to amplifier 34 its output would represent the distance between the input pattern and the reference pattern. Signals Xi are fed to weighted resistors 19, 24 ... of each of the further sections to provide one input of amplifiers 22, 24 ... whose other input is the output of weighted resistors 20, 25 ..., which are fed by a reference voltage. The outputs of amplifiers 23, 28 ... feed amplifier 34 to modify the distance signal. The modified distance signal from each amplifier 34 passes to a circuit which determines which one is the smallest, to identify the pattern.

Filed: 1954-08-13
Abstract: 752,207. Fastenings operated from a distance. SPECIALTIES DEVELOPMENT CORPORATION. Aug. 13, 1954 [Jan. 28, 1954], No. 23551/54. Class 44. [Also in Group XXVIII] A latch mechanism for normally holding a valve 30 pivoted on a shaft 49 in an open position is released by pressure responsive means 17. The latch comprises a lever 50 pivoted at 51 on the valve 30 engaging a fixed pin 52 at one end and pivoted at the other to a trigger 54. The means 17 comprises a bellows 82 which is expanded by pressure in a duct 79 and moves a rod 86 outwards. A trigger catch 98 forces the trigger 54 down against the action of a spring 66 and engages behind the trigger. When the pressure in the duct 79 falls to a predetermined valve a spring 87 draws the rod 86 inwards and the catch 98 engages the trigger 54 which pivots the lever 50 causing it to disengage the pin 52 and the valve closes under spring pressure. To reset the valve'to the open position a rod 96 is manually pulled to the lift. The rod 96 has a pin 100 which engages a forked lever 99 pivoted on the shaft 49 and the lever 99 engages a surface 45 to swing the valve to the open position. A tapered surface on the upper end of the lever 50 engages the end of the pin 52 and forces it to move axially against spring pressure until it registers with and springs into a gap 55 in the lever 50.

Title: Welding parts carrying a metal coating
IPC: B23K11/16
Filed: 1971-04-19
Abstract: 1353775 Welding by pressure O A BECKER 19 April 1971 [10 March 1970 3 Feb 1971] 23612/71 Heading B3R [Also in Division C7] In welding metal parts one of which is coated on one or both sides with a metal, which may hinder welding, the coating, at an area adjacent the weld to be formed, is cut away on one or both sides. The parts may be of zinc or tin coated iron or steel. Iron plate 1, Fig. 1, zinc coated on both sides 1a, 1b is to be welded to iron plate 2 zinc coated on both sides 2a, 2b and coated with plastics at 3. The overlapped plates are passed between milling cutters 4, 5 which remove the outer coatings of the plates and then between roller electrodes 6, 7 which weld the plates. The milling cutters may be narrower than the electrodes. In a modification milling is performed on the upper plate to reduce the thickness of the plate at 1e, Fig. 3, and the undersurface of the same plate is also milled to leave a projecting web 1g. A plastics foil 8 is provided between the plates which are electrically connected by clamp 17 so that current passes from an upper electrode 6 through the upper plate to the lower plate and through a bared region of the lower plate, heat beneath the electrodes melting the foil adjacent the web 1g and roller electrode welding of the web to the lower plate is effected. The foil maybe omitted when contact between the web and lower plate only occurs under electrode pressure. The web may be triangular in section, the upper plate is coated on both sides with plastics and current is passed between an upper roller electrode or an edge of the upper plate and the edge of the lower plate, the outer surface of the lower plate remaining undamaged. For spot welding the rib is replaced by an annular projection or after removal of circular areas on a metal coated upper plate electrode pressure causes the plate to make local contact with the lower plate for two spaced spot welds. Stepped holes 18, 19, Fig. 7, may be milled in the plates and deformed steel discs 20, 21 are arranged in the holes to engage a member 22 and become welded thereto and to the plates by electrodes 30, 31. Rivet like members may be placed in the holes and welded together. Zinc may be applied to fill the milled zone of zinc coated plates by a device which supplies a rod of zinc towards the milled area provided above a seam or spot weld and heats it by a resistance heater, by a device which supplies molten zinc from a container or by an electrolytic device having an electrolytic impregnated fabric in contact with the milled area.

IPC: C22C14/00
Filed: 1963-06-13
Abstract: A process for producing superconductive wires and bands from a titanium-niobium alloy composed of 20-45% by weight of niobium and the remainder titanium comprises, rapidly cooling down, e.g. by air or water quenching, the alloy from a temperature in the b  phase region to retain said phase and in addition a martensitic phase but no equilibrium a  phase and cold working the alloy into wires or bands which are heat treated between 250  DEG C. and 650  DEG C. to cause the supersaturated b  and martensitic phases to separate out. In an example a 10 mm. thick bar containing 33% by weight of niobium, remainder titanium, is cast under argon, e.g. in a water cooled copper mould, hot and cold rolled into a 2 mm. diameter rod, heated to a temperature in the b  range, e.g. 900  DEG C., and quenched in water so that no a  phase is produced.  The rod was subsequently cold drawn to 0.2 mm. in diameter and one portion annealed for 24 hours at 375  DEG C. and another for 24 hours at 590  DEG C. The degree of deformation from the initial casting to the finished wire or band is between 60-99%, preferably between 90-99%.  The superconductive properties of the resulting wire at 5  DEG K. are given with and without a magnetic field.

Filed: 1927-09-08
Abstract: 290,879. Crowe, R. J. S., and Green, W. A. Sept. 8, 1927. Supplying and controlling consuming devices.-An electric lighting system for buildings, theatres, &c., and particularly adapted for colour effects in a dance hall comprises a main lighting system (white lights) and an auxiliary lighting system (coloured lights) with dimming resistances in each and control switching apparatus adapted to light the main system only or to gradually switch out the main circuit simultaneously with the switching on and automatic variations of the lighting in the auxiliary systems. The main system may have two auxiliary circuits which are dimmed simultaneously, but one being left alight when the other is switched off; alternatively, one may be dimmed in as the other circuit is dimmed out. The motor operating the main system dimmers is automatically switched off after each operation of the dimmers. The auxiliary (coloured) system may comprise a number of circuits with dimmers operated according to a pre-arranged scheme by a separate electric motor controlled by the apparatus. A pair of push buttons 26, 27 operating linked double-throw switches control the system. The first switches on the main system and the second the auxiliary system through electromagnetic switches 3, 4 respectively. The linked switches act as starting and reversing switches for the main system dimmer motor 14 and the dimmers 8, 12 are coupled by a rod 16 operating (a) limit switches 17, 18, 20, 21 for the motor, (b) a switch 19 which opens the main lighting circuit switch 3 when the main circuit is dimmed, and (c) a switch 22 which opens the auxiliary system switch 4 when the main system is fully illuminated. The motor 39 operating the auxiliary system dimmers is controlled by the switch 4. For purposes of test and adjustment reversing switches 33, 35 are installed near the dimming apparatus to enable the system to be operated independently of the push buttons and switches 38, 41 enable the dimmer motors to be rendered inoperative to maintain the illumination of either system in any desired condition. The auxiliary system may be energized and controlled independently of the automatic operation by a doublethrow double pole switch 9 and the main system may be switched on at any time by an emergency switch 31. A similar arrangement on a three-wire supply system is also described.
