Abstract: 673,793. Armature windings for dynamoelectric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 8, 1950 [Nov. 14, 1949], No. 27293/50. Class 35. An armature winding without a magnetic core is made by covering the outer surface of a mandrel with thermosetting plastic material, winding the rotor winding on the mandrel, baking the assembly to harden the plastic material and removing the mandrel. The mandrel 20, which is preferably slightly tapered for ease of removal, carries five rows of pins 21, 22, 23, 24 and 25, inserted into radial holes in the mandrel and about which the winding 11 is wound. Before the insertion of the pins, a steel ring 13 which houses the bearing 14 and may be knurled to improve the adhesion to the end windings, is placed over the end of the mandrel. The mandrel body is lubricated and covered, together with the ring 13 with a thin porous paper or tape 26 on which the thermosetting plastic 29 is spread. After binding with wire 28 and removing the pins, the mandrel and winding are baked to harden the varnish. The binding wire is then taken off and the mandrel withdrawn from the winding. If desired, a two-layer winding may be produced by leaving the pins in position during the first baking and applying a second winding. The shaft 9 is then screwed at its cup-shaped end portion 12 to the end of a further mandrel which fits within the cylindrical winding unit. The outer surface of the shaft end portion may be knurled and is bonded to the end of the winding by baking with a further thermosetting plastic, the winding being bound with wire or tape, if desired. On cooling, the mandrel is unscrewed and removed while a commutator 16 is pressed on to the shaft 9 and connected to the wires 27. In service, the working flux from the poles 4 passes through the armature windings to a fixed solid or laminated core 7.

Title: An improvement in electric contact seam welding machines
IPC: B23K11/06
Filed: 1927-10-18
Abstract: 304,348. Meacher, W. Oct. 18, 1927. Welding. -In a roller electrode machine for welding the lapped edges of plates, sheets &c., the electrodes are driven by chain gear at a peripheral speed in excess of that of the work in order to allow for slip in the drive so that the speed of the electrodes during operation is not less than that of the work and burning of the weld is then avoided. The work is secured by clips 1, 3 to a bar 2 which is traversed through the electrodes 5 by a rack driven by a pinion 4 geared to a shaft provided with a clutch which is put in by hand and disengaged by an adjustable stop carried by the bar 2. The shaft carrying the pinion 4 is connected bv a free wheel clutch to the shaft driving the electrodes, so that the bar 2 may be pushed back without rotating the electrodes. The electrode driving shaft is connected by an open belt and cross belt respectively to shafts which through chain gear drive the electrodes in opposite directions. The electrodes are carried on arms 14 connected to the flexible strips 13 forming the secondary of a transformer and freely movable on pivots 29 fixed in the bearing, the lower arm being adjustable by a screw 15 and the upper arm being normally pressed down by a spring 16 but being raised for the insertion of the work by toggles 19 and hand lever. The welding pressure is applied solely through hardened steel rollers 17 which also serve to keep the electrodes to the correct shape. The electrodes are mounted on the arms between watercooled cheeks 20, one of which is pressed in place by a spring steel member 21 carrying a screw 22. The centre of the electrode has a square hole to receive the squared end of a spindle 24 which may be held in position by a spring pin 25 and may be removed for the purpose of changing warm electrodes. A switch 11 in the primary circuit of the transformer is operated by an adjustable tooth 7 on the bar 2 which engages a pawl 8 hinged to the end of a spring-returned slide 33 carrying an element of the switch. The pawl 8 is disengaged from the tooth by sending up a fixed stop 9 and is held in this position by a spring pawl 30. A stop on the bar 2 engages a lateral projection on a rock shaft which is arranged parallel therewith and has a lug for lifting the pawl 30 to allow disengagement of the switch and also a separate lever for disengaging the clutch on the driving shaft.

Abstract: 686,002. Forming selvedges; circular looms. COOPER, H. J. Oct. 24, 1950 [Oct. 31, 1949], No. 27797/49. Classes 142(ii), 142(iii) and 142(iv) Selvedges, Fig. 12. Alternate picks 69 extend beyond the edges of the fabric and, after the shed has changed, are turned into the new shed at 69a, a pick 70 being then inserted into that shed to fill the gap between the ends 69a.. The extremities 69b, 70b of the wefts are brought through to one face of the fabric. The junctions of successive pairs of picks are staggered.. Separate fabrics can be woven side-byside by forming such selvedges at gaps in the warp. Selvedge mechanism, Figs. 3, 4. The invention is applied to a circular loom for weaving a number of flat fabrics. At each side of a gap in the warp 26, an arm 6 is provided to turn in the weft ends and hooks 27 are provided to draw the ends through the fabric. The end of a weft being laid by a shuttle is clamped by a leaf spring 8 on an arm 6 and lies along a channel 7; after the shed has been changed behind the shuttle, the arm 6 turns to the chain-line position, Fig. 4, thereby taking the weft end into the new shed; a hook 27, previously raised through the warp into a cavity in the fell ring 2, now descends to draw the weft end through to the underside of the fabric. The next shuttle lays a shorter weft, the end of which is clamped against the fell ring by raising an arm 74, Fig. 4; when the shed has changed, the hook 27 again descends to draw the end of the weft through the fabric. For the next two picks, a hook 27a operates instead of the hook 27, thereby staggering the weft ends. Weft cutting. Where the shuttles emerge from the shed at gaps in the warp, the weft is cut by a blade (not shown) coacting with a fixed blade on the fell ring. Trimming weft ends. The weft ends protruding from the fabric are trimmed' off by rotating blades (not shown) as the fabric passes up the inside of the fell tube 2.

Abstract: 657,073. Operating circuits discharge lamps. GENERAL ELECTRIC CO., Ltd., and WILLIAMS, C. E. Oct. 26, 1948, No. 27824. [Class 38 (iv)] To render the total cathode heating independent of the setting of the dimming control in a hot cathode discharge lamp circuit of the kind in which dimming is effected by a variable ballast impedance in series with the lamp and in which cathode heating is provided in part by a filament transformer, the primary winding of the filament transformer is supplied through a variable regulating impedance automatically controlled by adjustment of the ballast impedance in such a sense that an increase in the ballast impedance results in a reduction of the regulating impedance, and vice versa. The impedances may be chokes provided with movable iron plungers, tappings, or D.C. control windings, the control elements of the two chokes being mechanically ganged. Alternatively, indirect control of the regulating impedance may be effected by voltage variations, e.g. across the lamp, resulting from the different adjustments of the ballast impedance. Fig. 4 shows such an arrangement, in which a lamp 5 supplied from a source 1, 2 through a D.C. controlled saturable ballast reactor 8, 9, which may be provided with a D.C. feed-back winding (not shown), has cathodes 6, 7 partially heated by a filament transformer 10-12, the primary winding of which is fed from the source through a D.C. controlled regulating reactor 13. The control winding 14 of the reactor 13 is energized, through a rectifier 15, in accordance with the voltage across the discharge path of the lamp, the sensitivity of this control being increased by a reaction winding 20 fed from a rectifier 19 responsive to primary current. The single lamp 5 may be replaced by two, or more, connected in series, their several cathodes being supplied from a single filament transformer. A plurality of parallel operating lamps may have separate ballasts.

Title: Fuel injection systems for diesel engines
IPC: F02D7/00
Filed: 1975-07-02
Abstract: 1471634 Fuel injection systems SULZER BROS Ltd 2 July 1975 [2 July 1974] 27857/75 Heading F1B A fuel injection system, for a diesel engine, comprises an injection valve 1 which has a pressurized fuel inlet, connected to line 2, and is connected by a control duct 5 filled with fluid to an injection controller 4, and is arranged to be opened by pressures in the control duct exceeding a threshold pressure, while the injection controller 4 is arranged to supply to the control duct 5 periodic pressure pulses whose duration is variable up to a maximum duration, and whose pressure is not less than the mean of the threshold pressure and the pressure supplied to the control duct between pulses, but is less than the threshold pressure and whose maximum duration is less than twice the time taken for a pressure wave to travel through the fluid along the length of the control duct. Pressurized fuel from line 2 passes through passage 16 to nozzle 17 and also acts on the top of plunger 24 which bears on piston 20 which is connected to needle 15. Pump 6 provides pressurized fuel in delivery line 8 and to a valve 12, which in a first position discharges the fuel to a sump 7 and in a second position connects line 8 to control duct 5. Valve 12 is operated periodically to open for the injection period and as it opens the pressure in line 8 propagates into control duct 5 as a positive pressure wave which moves at sonic speed. When valve 12 closes there is an abrupt drop in pressure which propagates into duct 5 as a negative pressure wave. When the leading edge of the pulse reaches injector 1, the pulse is reflected and produces a pressure which is greater than the control pressure and acts on piston 20 to enable needle 15 to lift. The injector remains open for a period of time corresponding to the length of the pulse. When the reflected pulse reaches the valve 12, its energy is dissipated through valve 14.
