Title: Machine for making metal closure caps
Inventor: FORD GEOFFREY EWART
IPC: B21D51/46
Filed: 1960-06-02
Abstract: 913,251. Shaping metal foil caps. FORDS (FINSBURY) Ltd. June 1, 1961 [June 2, 1960], No. 19558/60. Class 100 (2). A machine for making skirted metal foil caps having liners of paste-board or other sealing metal comprises two tool parts A, B, a strip 10 of aluminium foil being fed between the parts. The tool part A includes a shear-ring 1 mounted on a support 2 which is secured to a front plate 8 of the machine. A mounting member 5 having a tubular part 12 is also mounted on the plate 8 and slidably receives a rod 13 in the part 12. The rod 13 is of reduced diameter at its inner end which constitutes a forming punch 4. Slidably mounted on the punch 4 is an ejector ring 3 which is urged by a spring 14 to a position in which a step 3a thereon abuts against the rear face of the shear ring 1. The ejector ring has a transverse slot 3b formed therein aligned with a similar slot 2a in the support 2; a strip 6 of liner material is fed through the slot 3b in step-by-step fashion in unison with the movement of the metal strip 10. The rod 13 is reciprocated by a crank, eccentric or cam. The tool part B includes an annular shearing and forming member 20 mounted on a piston 21 which is reciprocable by means of a crank or eccentric in a cylinder 22 carried by the front plate 8. The piston 21 also carries a central member 27 to the inner end of which an embossing die may be secured. Spring-biased pressurerings 23, 25 are slidably mounted on the parts 20, 27, respectively. In operation the punch 4 and piston 21 are moved together and apart, inward movement of the punch 4 from the position shown causing a disc 6a of liner material to be sheared from the strip 6 against a corner 3c of the front part of the bore of the ejector ring 3 and carried on the punch to a position approximately level with the front surface of the ejector ring. As the piston 21 moves inwards first the rings 23, 25 grip the metal foil 10 and then the member 20 cooperates with the shear ring 1 to cut out a circular blank from the foil. Continued inward movement of the piston allows the member 20 to shape the peripheral parts of the metal foil blank round the forming punch 4 to form the cap skirt, the ejector ring 3 being moved backwards against the action of the spring 14 during this operation. The piston and forming punch then move apart and the ring 3 pushes the formed cap with the liner disc therein off the end of the punch. The strips 6, 10 are advanced one step and the cycle is repeated. Specifications 667,301, 756,440 and 778,615 are referred to.

Abstract: 738,063. Converting rotary into oscillating or reciprocating motion. HARRIS-SEYBOLD CO. July 15, 1953 [July 22, 1952], No. 19637/53. Class 80 (1). Oscillatory movement of a shaft 27, which may drive through a gear 28 a rack 11 attached to a reciprocal body such as the bed of a printing machine, is obtained from a continuously driving gear 12. The gear 12 drives a shaft 14 in one direction through gear 13 and a shaft 20 in the opposite direction through gears 13, 21. Shaft 14 carries a gear sector 15 and shaft 20 a gear sector 22 which are adapted to engage alternately with a pinion 32 on the driven oscillatory shaft 27 to drive it in one direction and then the other. For accelerating the shaft 27 from zero before the gear sector 15 engages a roller 19 carried on an arm 16 on the shaft 14 engages a cam arm 35 on the shaft 27 and for decelerating after the toothed engagement another roller 18 on arm 16 engages another cam arm 38. Rollers 39 and 40 on shaft 27 co-operate with cam surfaces 41, 42 respectively on the arm 16 to maintain the rollers 19 and 18 in engagement with the arms 35 and 38 respectively during the above operations. For driving the shaft 27 in the opposite direction the gear sector 22 has associated rollers 25, 24 and cam surfaces 45, 46 for cooperating with cam arms 36, 37 and rollers 43, 44 on the shaft 27 for effecting the accelerating and decelerating movements. The motion of the shaft 27 obtained with the arrangement shown is substantially identical in both directions of movement but if a greater speed of travel in one direction is desired different sizes of the gear segments 15 and 22 could be provided with separate co-operating gears on the shaft 27.

Title: Improvements in or relating to automatic liquid level control devices
IPC: G05D9/02
Filed: 1957-06-22
Abstract: 844,643. Controlling liquid levels. FRANKMANN, H. May 20, 1958 [June 22, 1957; Nov. 6, 1957], Nos. 19716/57 and 34559/57. Class 123(1) A liquid-level maintenance device, especially for the oil sump of an I.C. engine, has a reservoir 16 and a container 12 with a float-controlled valve assembly therebetween. The flow between the float-chamber 10 of said assembly and the container 12 is restricted so that the level in the former coincides with the mean working level 15 in the latter. The liquid is conveyed from the reservoir by a pipe 17 connected to the float-chamber which has a float 11 therein adapted to actuate a ball-valve to regulate the supply. In the event of the supply failing the float lowers into engagement with electrical contacts to effect a warning. The valve assembly may be connected to the side of the container 12 by a pipe 13 or to the base by a pipe 13a and may be provided with a breather vent 10a, a slotted bracket 19 which allows vertical adjustment and level indicator windows. The valve may be actuated by a solenoid and the static liquid level is indicated by the reference numeral 18. In a modification, the valve 20, Fig. 2, is double-acting having a lower seating 21 and an upper seating 22. The raising of the level in the sump causes the float to rise and cut-off the supply.

Title: Improvements relating to inductive windings
IPC: H02P7/34
Filed: 1945-07-11
Abstract: 595,665. Exciting dynamo - electric machines; modifying reactive characteristics of electric circuits. ENGLISH ELECTRIC CO., Ltd., and SHAW, N. H. July 11, 1945, No. 19764/46. Divided out of 595,660. [Classes 35 and 38 (iv)] [Also in Group XXXVII] Direct-current circuits containing inductive windings are arranged to provide time-constants which differ from the natural time-constants of the inductive windings. A bridge comprises two sections of an inductive winding arranged in opposite arms, and two resistors arranged in the other opposite arms. A direct-current generator supplies two opposite terminals of the bridge and a field winding of the generator is excited according to the voltage between the other two terminals. The invention is shown as applied to the field windings of a Ward- Leonard generator 2 supplying a direct-current motor 1. The generator field winding is divided into two equal sections 34 and 35 which are arranged as the opposite arms of a bridge, the other arms of which consist of resistors 36 and 37 having equal resistance-values with the sections 34 and 35. An exciter 3 supplies bridge terminals E and F and an auxiliary exciter field winding 38 is energized from terminals G and H. Under steady current conditions the bridge is balanced, but when a potentiometer 25 is adjusted to increase or decrease the generator field excitation, the bridge becomes unbalanced due to the time lag of the coils 34 and 35, and a current is passed through the winding 38 in such a, direction as to change the excitation of the machine to accelerate the change of current in the windings 34 and 35. Switching means may be inserted between the bridge terminals G and H. A rectifier may be placed in series with the auxiliary field winding. Alternatively, the field winding may be connected to the unidirectional output terminals of a bridge rectifier, the input terminals of which are connected to the terminals G and H. Adjustable resistors may be connected in adjacent arms of the bridge rectifier. Specifications 528,789, 594,951 and 595,660 are referred to. '
Patent GB-1086850-A (GB)
Title: Electronic musical instruments
IPC: G10H1/04
Filed: 1966-05-04
Abstract: 1,086,850. Electronic organs. WURLITZER CO. May 4, 1966 [May 7, 1965], No. 19774/66. Heading G5J. An electric organ which may be a percussive circuit in an electrophonic organ of the type employing a master oscillator and frequency dividers, comprises a circuit which amplitude modulates the outputs of tone generators to produce percussive effects, which circuit is controlled by a continuously running oscillator, the phase of which returns to zero on closure of a key. Thus the percussive circuit can be synchronized with the main instrument. As described, tone signals from tone generators 58 are applied under conventional control of keys 60 and stops 62 through a preamplifier 68, or in the case of percussive tones, through a preamplifier 168 and a switch contact 164 in the position shown, to an amplifier at 76. Bongo or pizzicato percussion tones can be selectively connected under key control to bar conductors 232 or 280 and 286, and are applied through amplifiers 244, 178 and 120 to input 114 of a light-sensitive resistor 98. Closure of one of the key-operated switches 314 applies a pulse to a monostable circuit 217 momentarily switching transistor 281 to conduction illuminating a neon lamp 100 through a transistor switch 255. The light sensitive resistor 98 is thus switched to conduction and gradually returns to its high resistive state. A sawtoothshaped envelope (Fig. 3, not shown) of the tones applied at 114 is thus passed through a volume control 92 to preamplifier 68 thus superimposing the selected percussion. If the ganged contacts of a switch 159 are moved to their other position the tones from the preamplifier 168 are applied through amplifier 120 to the light-sensitive resistor 98. A tone generator 354 is simultaneously connected to the input of the monostable circuit causing it to operate as a triggered oscillator, the phase of which can be reset by closure of any of the switches 314. The lamp 100 is periodically switched on at the frequency of the triggered oscillations, which frequency depends on the setting of an adjustable potentiometer tap 346. The light-sensitive resistor 98 thus " sawtooth " modulates the combination of tones from the preamplifier 68, producing a rhythm effect. A permanently illuminated lamp 102 stabilizes the lamp 100. In a modification the circuit comprising the light-sensitive resistor, the lamps and the transistor switch 255 are replaced by a transistor circuit (Fig 5, not shown).

Depression of a reset key 1 and slide 2 causes a pin 2a to rock a lever 5 clockwise so withdrawing drive pinions 6 from engagement with numeral wheels 7. The pin 2a then rocks a bridge 8 to push fingers 9 against heart cams 11 to turn the wheels 7 to zero. At this point a pin 13 on bridge 8 passes a shoulder 14 so that a lever 15 pressed by a spring 16 locks the fingers 9 and therefore the numeral wheels. Release of the key 1 permits the slide 2 to return under the action of a spring 3, a pin 2b releasing the lever 15 after the drive pinions 6 have re-engaged the numeral wheels.

Filed: 1954-07-08
Abstract: 780,382. Axial-flow compressors. ROLLSROYCE, Ltd. July 8, 1955 [July 8, 1954], No. 20086/54. Class 110 (1). A multi-stage axial-flow compressor includes two relatively rotatable rows of blades, the upstream row having parts near the blade roots which form a platform which is inclined, at least at the downstream side, away from the working fluid passageway so that part of the working fluid stream is directed towards the upstream edge of a shroud carried around the blade tips of the downsteam row, thereby increasing the static pressure adjacent the upstream edge of the shroud so that the leakageinducing static pressure difference between the upstream and downstream edges of the shroud is eliminated or reduced. In the compressor shown, the stator blades 12 are provided at their tips with a shroud 14. Rotor blades 10 are fixed to rotor discs as 11 by fir-tree roots 10b and are each provided with a platform 10c which is either straight or curved in longitudinal section, as shown, and arranged so that its downstream edge directs a jet of working fluid against a recess 15 formed in the upstream edge of the shroud 14. The velocity head of the jet of fluid is thereby converted into static pressure head. Axially and radially extending plates may be provided to partition the recess 15 into segments so as to convert any circumferential component of velocity into pressure head. The resultant increase of static pressure at the upstream edge of the shroud 14 reduces or eliminates the pressure difference between the upstream and downstream edges of the shroud 14 and consequently reduces or eliminates the recirculation of working fluid from the outlet to the inlet of the blades 12 around the shroud 14. Sealing rings 16 may be provided to co-operate with flanges 17. The platforms 10c may be straight as viewed in the direction of the rotational axis of the compressor or may be curved about the axis. The shroud may be formed at the tips of the rotor blades, the surface of the stator casing at the stator blade roots diverging outwardly to direct a jet of working fluid against the upstream face of the shroud.
