Title: Coil winding process and apparatus
IPC: H02K15/04
Filed: 1973-07-13
Abstract: 1385619 Winding stator coils BALZER & DROLL KG 13 July 1973 [28 Feb 1973 18 April 1973] 33612/73 Heading B3A A coil winding process comprises the steps of feeding wire 18 in a winding plane around a former 30 and simultaneously urging wound loops obliquely of the winding plane by reciprocal movement of a stripping device 38, 42, 46, 50 into and out of engagement with the wound loops to cause detachment of completed loops from the former and leave space for further winding. The former is stationary and comprises a number of stages which may be individually aligned with the winding plane. The wire 18 is led to a stage 34 via a guide 20 rotating about the former. The stripping device comprises plates slidable in slots 40, 44, 48, 52 and driven by tappets 54 located in a perforated disc 56. Springs 58 urge the tappets against a swashplate 60 having an inclined surface 64. Rotation of surface 64 by shaft 65 transmits reciprocal motion to the tappets via ball bearings 72. In operation the winding layer is displaced downwardly on stage 34 and is continuously removed to be received by a transfer tool 28 which has pins 74 insertable in openings 76 of the former. The coil can be subsequently inserted into a stator of an electric machine. After the windings are stripped off the former and forced on the tool, wire 18 is placed in a holder (96), Fig. 3 (not shown), to form an intermediary loop 98, Fig. 4, and hold the wire taut. The plates are moved upwardly and the tool 28 is indexed to receive a subsequent coil. The winding former 30 may have each stage 34 sub-divided over a part of the circumference into several fine stages (134), Fig. 8 (not shown), to vary the length of the winding within a particular stage. The former need not be symmetrical about its axis, Fig. 9 (not shown), and may be divided into two parts, Fig. 10 (not shown), to enable adjustment of overall diameter.

Title: New or improved means for harvesting grain and other crops
Inventor: MEADOWCROFT FRED
IPC: A01D41/00
Filed: 1957-10-30
Abstract: 854,184. Grain harvesters. HARRISON, McGREGOR & GUEST Ltd. Jan. 7, 1959 [Oct. 30, 1957], No. 33796/57. Class 6(3). A harvesting machine which comminutes the entire crops and then separates out the grain comprises a shrouded powerdriven shaft carrying flails 11, a separating drum 19 for sifting the grain from trash and a duct 18 connecting the shroud 16 with the drum and through which the comminuted crop passes. The device is mounted on a wheeled chassis 45 which, as shown, is self-propelled by an engine 13 driving the front wheels 12, the rear wheels 44 being steerable. The engine also drives the flail-shaft through a belt-drive 15, the entire housing 16 being adjustable pivotally through a screw 21. The duct 18 is fixed but a flanged extension integral with the flail housing 16 is slidable within it. The drum is carried on rollers 24, 26 and is driven frictionally by a belt 27 which passes over the forward rollers 24 and under the drum. The drum comprises three concentric shells, the outermost being imperforate except at the rear end and the inner two being foraminous but having different mesh sizes. Grain and chaff pass through the innermost drum and chaff is retained on the outer surface of the intermediate shell while grain and weed seeds gravitate to the outermost shell. The perforated rear end of this shell separates grain from the weed-seeds, the latter falling through the grid into a hopper 38 and the grain entering a discharge channel containing a screw conveyer 39 feeding a bagging shoot 40. Rods within the drum 19 tumble the crop, and the separated products are fed along the annular spaces by helical ribs attached to the two outer shells. The device can be used for harvesting forage crops, in which case the separating means is by-passed and the crop passes directly to a trailer.

Title: Apparatus for producing multiple sheet glazing units
IPC: C03B23/24
Filed: 1956-11-06
Abstract: 798,007. Multiple glazing units. LIBBEYOWENS-FORD GLASS CO. Nov. 6, 1956 [Nov. 14, 1955], No. 33803/56. Class 56. Relates to the manufacture of multiple glazing units wherein a pair of spaced sheets 20 are supported by vacuum platens 35 on a carriage 29 for passage through four treatment stations A, B ... within a furnace 25, each station comprising a base 62 carrying pairs of fusion burners 59, shaping rollers 60 and finishing burners 61 between which the edges of the sheets pass for shaping and welding, the sheets being rotated through a right angle when passing between one station and the next. The invention provides for detecting and correcting any misalignment that may occur at any station between the edges of the sheets and the shaping and sealing burners and rollers. The detecting device 72 carried at the front end of the base 62 comprises two spaced blocks 78, 79 between which the edges of the sheets pass. Block 78 has two ports 84, 86 communicating with an air-pressure supply 87 and registering with ports 90, 91 in the other block 79. Port 86 is one half the size of port 84 ; ports 90, 91 communicate with opposite sides of a diaphragm 94. The normal position of the sheets is that in which the sheets block the top half of the port 84; any departure from this normal causes a differential pressure on the opposite sides of the diaphragm which causes a jet tube 98 to discharge oil under pressure from pipe 99 into one or other of the pipes 104, 106. These pipes communicate with a four-way valve 75 to control the supply of high-pressure oil from pipe 109 to an interlock valve 76 from which the high-pressure oil may be passed to a cylinder 77 either by pipe 125 or 126, depending on the position of the four-way valve 75 so as to raise or lower the base 62 which is carried by a framework 130 to which the piston rod 129 is connected. The interlock valve 76 is normally in the position shown, but on de-energization of a solenoid 124 the spring 123 puts pipes 115, 118 from the four-way valve into communication with pipes 125 and 126 respectively (through bores 121, 122). The electric circuit in which the solenoid 124 is contained includes a start switch 130<SP>1</SP> and a stop switch 139 tripped by the carriage 29 as it moves through the furnace. A slightly modified detecting device 72 is described wherein all the air ports are equal in size with the lower ones provided with baffle plates.

Filed: 1928-02-21
Abstract: 312,139. India Rubber, Gutta Percha, &, Telegraph Works Co., Ltd., and Avery, W. L. Feb. 21, 1928. Springs, arrangement of.- Relates to resilient mountings for the wheels of vehicles and particularly aircraft, in which the wheel moves relatively to the axle in a plane at right angles thereto against the action of resilient members in the mounting. The wheel is constrained to move with its axis parallel with the axle by means of a parallel linkage. The mounting comprises a cylindrical casing 1 with fixed and removable end plates 2, 3 slotted at 14, 15 for the passage of the axle 13. The wheel 10 rotates on bearings 8, 9 carried by the casing which is prevented from longitudinal movement on the axle by split clips 16, 17 secured to the axle and having flat portions engaging the sides of the slots 14, 15. The resilient members comprise groups of wedgeshaped indiarubber blocks 31, with metal separating plates 32, mounted in annular recesses 27 in members secured inside the casing, the blocks 31 and plates 32 having interengaging projections and recesses 33. The blocks of a group are compressed against a fixed partition 28 in the recess bv a movable vane 30 carried by a coverplate 29 which is fixed to a link 19. Two pairs of links 19 and four groups of blocks are provided, the links being each pivoted at one end to a pin 21 fixed to the casing while their other ends are pivoted to a sleeve 18 sliding on the axle. The axle normally lies at the upper ends of the slots 14, 15 but the inclination of the links is such that an upward shock moves the sleeve 18 towards the right and the vanes 30 carried by the links compress the rubber blocks. Recoil buffer-rings 34 are fitted on the axle between the plate 2 and a flange 36 of the sleeve and these rings serve also to cushion severe shocks when the links 19 are swung round to the extreme end of their travel. According to the Provisional Specifications, the sleeve 18 is mounted on a tube extending across the casing, and having flanged ends abutting the ends of the casing, the axle being passed through this tube. The first Provisional Specification describes an arrangement in which a single pair of upwardly extending inclined links is used, movement of the wheel being resisted by springs or indiarubber rings arranged between a flange on the sleeve 18 and one end of the casing.

Filed: 1968-09-19
Abstract: 1,268,738. Electro-machining. PRODUCTION ENG. RESEARCH ASSOCIATION. Jan. 31, 1969 [Sept. 19, 1968], No.33916/71. Divided out of 1, 255, 930. Heading C7B. In electro-machining, the electrical potential applied between the tool and workpiece is controlled in response to measurement of the electrical potential between voltage probes disposed in the machining area, through which electrolyte flows, in electrical contact with the tool and workpiece. The electrical potential applied may be further controlled in response to the electrical conductivity of the electrolyte measured immediately before flowing between the tool and workpiece. E.g. a reference voltage is algebraically added first to a voltage derived from the conductivity measurement, then to the potential on one of the probes, the resultant sum being fed with the potential on the other probe to the inputs of a differential amplifier, the output controlling the power supply producing the electrical potential.

Title: System for unloading gas compressors
IPC: F04B49/16
Filed: 1954-11-26
Abstract: 759,734. Fluid-pressure servomotor control systems. COOPER-BESSEMER CORPORATION. Nov. 26, 1954 [Dec. 15, 1953], No. 34312/54. Class 135. The volume of the clearance space and hence the output of a gas compressor 10 having an inlet 12 and an outlet 13 to a tank 32 is regulated by a piston 15 in a cylinder 14 forming an. extension of the compressor cylinder, the position of the piston being determined by an hydraulic servomotor 18, the flow of liquid to and from the opposite ends of which is controlled by a pilot valve 22. The position of the piston 31 of the pilot valve is dependent on the pressure on a spring-loaded diaphragm 34 forming one wall of a chamber 35 connected to the compressed gas tank 32. The servomotor is connected by flexible pipes 20, 21 to ports 20a, 21a in the pilot valve which is formed with recesses 23, 25 connected to a return pipe 26 to a liquid tank, and a recess 24 connected to the discharge pipe 29 of a pump 27. The pressure to be maintained in the tank 32 is set by a lever 48 coacting with .a scale- 50 and pivoted to a slide 47 and connected by a link 49 to the body of the pilot valve 22, the arrangement being such that when the pressure in the tank reaches the set value the piston is in the valve closed position shown. A fall of pressure in the tank results in displacement of the piston 31 to the right, thus allowing pressure-liquid to flow through the pipe 21 to the servomotor 18, the piston of which moves to the right, thus reducing the clearance space of the compressor cylinder and increasing the pressure of the gas discharged to the tank 32. The increased pressure returns the pilot valve piston 31 to its valve closed position. A rise of pressure in the tank results in increasing the clearance space and reducing the pressure of the gas discharged to the tank. In the event of failure of the hydraulic pressure, a pressure-responsive device 39, e.g. a bellows, closes a normally open switch 39 and energizes a solenoid 43 which closes interconnected valves 45 in the pipes 20, 21 so as to lock the servomotor in the position it occupies at the moment of failure. To permit manual operation of the pilot valve piston 31, the piston rod 33 is disconnected from the diaphragm 3, 4, and a follow-up is provided between the servomotor and the piston 31 by a pivoted lever 52, one end of which is connected to a sleeve 51 adapted to be secured by a screw 51a to the rod 33.
