Title: Determining the speed of a rotating member
IPC: H02P6/17
Filed: 1974-06-13
Abstract: 1478049 Measuring angular velocity SIEMENS AG 13 June 1974 [14 June 1973] 26359/74 Heading G1N [Also in Divisions G3 and H2] The speed of the permanent magnet rotor 1 of a D.C. brushless motor, having windings 2 ... 5 respectively switched by transistors T1 ... T4 controlled by the outputs of a circuit 9 responsive to rotor-positions signals produced by Hall generators 6, 7 and applied to an amplifier 8, is determined by a circuit comprising capacitors C1 ... C4 connectible by respective transistors T6 to T9 to a constant current supply provided by members R1, R2, Z, T14 and dischargeable by respective transistors T10 ... T13, diodes D1 ... D4 and an interrogating device 11, the arrangement being such that transistor T6 ... T9 are also controlled by the circuit 9 so that each capacitor C1 ... C4 is charged to a voltage representation of the time required for a 90 degrees rotation of the rotor 1, after which this voltage is applied through the respective diode to the device 11 during the following 90 degrees rotation when the next capacitor is charged, the circuit 9 also controlling the transistor T10 to T 13 so that each capacitor is discharged during the next but one period of rotation following that during which it is charged. Thus a combined signal appears at the input to the device 11, which signal is directly proportional to each rotation period of the rotor and may be employed to maintain a constant tape velocity in a magnetic tape cassette device, by maintaining constant the sum of the squares of the rotation periods of the two motors driving the tape reels. Alternatively, the signal from the diodes D1 ... D4 may be fed to a division stage to obtain a speed signal for application to a speed controller 10 controlling a transistor T5 in series with the combination T1 ... T4 and 2 ... 5. The capacitors may be replaced by counting stages fed with digital signals or by D.C. motors, the former modification involving the use of a constant frequency generator connected via switching elements with the respective stages and the latter modification using the angles of rotation  of the D.C. motors as a measure of the rotation period of the rotor. Each combination T6, C1, T10 ... T9, C4, T13 may have its own constant current supply, Fig. 2 (not shown) or the supply R1, R2, Z, T14 may be changed to a different value as each transistor T6 ... T9 is switched on, both these modifications compensating for component variations. In Fig. 1 for example, a respective one of four resistors R1, each corresponding to a transistor T6 ... T9, may be connected to the transistor T14 when its associated transistor T6 ... T9 is switched on.

Abstract: 771,872. Control of A.C. motors. FERNSEH GES. Sept. 16, 1955 [Sept. 18, 1954], No. 26557/55. Class 38(3) The rotor and stator windings of polyphase motor 3 are supplied at different frequencies so that the speed of the motor is proportional to the difference of the frequencies, and hunting is prevented by arranging that each source has a high impedance to afternating-current and at -least one of the sources has a low resistance to direct-current. The source 4 for the rotor winding has chokes 6, 7, 8, in its output circuit so presenting a high impedance to alternating-current. The source 5 for the stator winding comprises output transformers 9, 10, 11, fed from a three-phase amplifier having valves 12, 13, 14, which are modulated by voltages with phase displacements of 120 degrees. The alternating-current impedance of the source 5 is at least three times that of the stator wind- .ing due to the internal impedance of the valves, whilst the direct-current resistance of the source is low compared with that of the stator winding by virtue of the lowresistance output windings of the transformers.

Filed: 1922-10-05
Abstract: 186,929. Hesselman, K. J. E. Oct. 8, 1921, [Convention date]. Regulating delivery by by-passes ; regulating delivery by opening suction valves. - In a fuel pump for internal-combustion engines in which the suction valve or a by-pass valve is kept open during the first and last portions of the delivery stroke, the valve is controlled by rectilinearly moving cams and means co-operating therewith, these cams and co-operating means having a relative movement at a rate proportional to the movement of the pump plunger, and either the cams or the co-operation means being adjustable while in operation to vary the movement and the period of injection. In one form, the suction valve 2 is kept open by a rod 3 operated by a lever 7 oscillated about a pivot 6 by rollers 8 on arms 10 which are reciprocated at a rate proportional to the movement of the pump plunger. On the spindle 9 of the rollers 8 are mounted two smaller rollers running on two stationary members 13, 14 provided with inclined surfaces 19, 22. When one of the small rollers is moving on the raised surface 17, the valve 2 is held open during the first portion of the delivery stroke, and when the other small roller is moving on the surface 20 during the return movement of the arms 10, the valve is opened during the last portion of the plunger stroke. By adjusting the member 13 by means of a screw 23, the movement at which injection begins is varied, and by adjusting the member 14 by hand or governor, the moment at which the injection ends and, therefore, the quantity of fuel injected, are varied. In another form, the cams are carried by the reciprocating member and the rollers are stationary, the reciprocating member and one of the roller-carrying members being adjustable. In another form, the cams are carried by the reciprocating members and the stationary rollers adjustable. In another form, the cam-surface 22 is on the lever 7, which is adjustable, and the other is on the member 13 on a lower level, while the rollers reciprocate between them.

Abstract: 1322841 Cables FUJIKURA CABLE WORKS Ltd 19 April 1971 [7 April 1970 8 June 1970] 27114/71 Heading H1A A method of making a cable comprises the steps of forming a metal/plastics composite tape, longitudinally wrapping the composite tape about a core with the metal surface innermost and finally extracting a plastics sheath. Metal tape 1, for example copper or aluminium is drawn from a drum 2, passed through a tension adjuster 6 and round a heating roller 7. A plastics tape 3 of width greater than that of the metal tape 1 is drawn from a drum 4 and fed together with the metal tape 7 between rollers 8 which apply pressure to heat bond the tapes to form a composite tape 9. As the plastics tape is of greater width it is left with at least one side portion which is not bonded to the metal tape. Folding device 10 folds these excess portions around the edges of the metal tape. Cooling device 15 cools the tape 9 before it enters a former 16 which wraps the tape about a core 11, with the metal innermost, so that the edges overlap and the folded over portion 14 of plastics tape is interposed between them (see Fig. 4). An extruder 17 extrudes a plastics sheath 5 which bonds to the plastics of the tape and also causes the overlapped portions of plastics tape to bond together. Preferred plastics for the composite tape are ionomer, ethyleneethylacrylate copolymer, ethylene-methylacrylate copolymer, ethylene-acrylic acid copolymer, ethylene vinyl acetate copolymer polyethylene and vinyl chloride.

Abstract: 150,198. Royce, F. H., and Rolls-Royce, Ltd. Nov. 4, 1919. Pistons, balancing laterally.-In order to avoid slap, the trunk piston of an internal-combustion or other engine is pressed against the side of the cylinder by means of a plunger c at the opposite side of the piston to that which takes the thrust on the power stroke. The plunger is pressed against the cylinder by a spring c<3>, or by fluid-pressure, or by both, and, in the first case, is arranged apprcximately in the plane of the gudgeon-pin. In 'the example shown, the plunger c is formed with a flanged head c' which fits into a recess in the piston skirt. The plunger is acted on by a spring, and by lubricant under pressure, which passes along a passage in the connecting-rod and an crifice b<5> to the space between the walls of the hollow gudgeon pin and an inner sleeve b<3> with enlarged ends closing the ends of the gudgeon-pin. The lubricant passes by passages b<6>, a<5> to a passage in a plug d, the exit of the passage being controlled by a blade spring d<5> forming a check valve. The gudgeonpin may be secured, either in the connecting-rod end, as shown, or in the bosses a<1>. The ports between the connecting-rod end, the gudgeonpin, and the piston bosses may be so formed that there is constant admission of oil, or so that the admission synchronizes with the greatest side thrust of piston. The invention is particularly applicable to an aluminium piston working in an iron cylinder.
