Title: Improvements in or relating to the correction of unbalance of rotary members
IPC: G01M1/36
Filed: 1962-12-28
Abstract: 1,022,420. Balancing grinding wheels. NEWALL ENGINEERING CO. Ltd., and A. J. RIDDINGTON. March 25, 1964 [Dec. 28, 1962], No. 48899/62. Heading B3D. [Also in Division F2] A grinding wheel 10 and its drive shaft are balanced by an attached unit incorporating a pair of adjacent counterweights 26 of equal mass and acting at the same radius, the weights being rotatable about the shaft axis in the same and opposite directions by electric motors 30 through reduction gear units 31. The weights consist of a series of longitudinal bars 26 in circumferential drillings in a pair of rings 19 carried by bearings 18 in a casing 16 bolted to a hub member 11. The motors are controlled by an electronic unit supplying pulses to operate the motors in equal step-by-step movements, and including a sensing head in the form of a vibration pick-up with a number of amplifying stages. In use the weights 26 are arranged angularly close to each other and rotated together in the same direction until the minimum unbalance position is reached, when the motors are stopped either manually or automatically, and a finer balance is then obtained by rotating the weights in opposite directions with a higher pick-up amplification. If desired the process may be repeated with still higher degrees of amplification.

Filed: 1975-12-08
Abstract: 1525409 Optical record/playback system TELETYPE CORP 8 Dec 1975 [9 Dee 1974] 50292/75 Heading G5R In an optical record/playback system in which during recording a modulated laser beam produces a series of depressions corresponding to modulating information along a track on a thermoplastic record and during playback reads the information by reflecting the incident laser beam to a photo electric detector, the power of the beam is reduced during playback and the light beam impinging on the record is elongated in a direction transverse to the record track. The record 12 is a disc on a turntable 16 rotated by motor 18 and the optical assembly is mounted on transducer arm 21 which is pivoted on shaft 29 below the turntable and pivoted continuously or stepwise by motor 31 in dependence on whether the record area 5 is recorded or to be recorded with a spiral or a series of concentric tracks. During recording horizontally polarized light beam 102 generated and modulated in laser 20 is passed to beam splitter 106 where because of its polarization it is reflected through 90 degrees to quarter wave plate 110 which circularly polarizes the beam. The beam is then focused on the record by object lens 112. During playback the beam is not modulated and the operation of solenoid 202 moves astigmatizer 104 comprising a plate with a single vertical slot 208 into the beam path. By diffraction this elongates the beam in the horizontal direction corresponding to an elongation transverse to the record track at the record and reduces the beam power below that required to write on the record. The light beam reflected from the record passes again through the quarter wave plate producing a polarization change of 90 degrees by virtue of the two transitions the resulting beam is now transmitted directly by the beam splitter to the photo detector 127. The beam power can be reduced by an attenuator and the beam can be elongated by an unidimensional (cylindrical) lens.

IPC: H03K19/096
Filed: 1969-10-15
Abstract: 1286991 Transistor pulse circuits TEXAS INSTRUMENTS Inc 15 Oct 1969 [30 Dec 1968] 50706/69 Heading H3T [Also in Division H1] A clock controlled pulse transfer stage 64 for a shift register includes a first FET 68 receiving the input pulse at its gate and the clock pulse # 1  through a capacitor 72 at its drain, and a second FET 70 receiving the clock pulse # 1  at its gate and having its drain connected to an output terminal, and a connecting circuit, including switch means such as FETs 76, 78 or a diode (150, Fig. 7, not shown), connecting FET 68 drain to FET 70 source. The FETs 76, 78 are in series and connected as shown, and a second similar stage 66 controlled by a clock pulse # 2  of a second phase receives the output of 64. The inclusion of the FETs 76, 78 is said to reduce the effects of currents injected into the substrate as a result of switching spikes (58, 62, Figs. 3b, 4b, not shown) passing through the P-N junctions (48, 50, Fig. 2, not shown) formed between the drain and source regions respectively and the substrate (46). In operation, if no input pulse is present to stage 64 FETs 68, 78 are off, a negative clock pulse # 1  then passing via capacitor 72 to cause FET 76 to conduct and to connect the clock pulse at 74 directly to the source of FET 70. The latter is also turned on by # 1  and so a negative signal appears at the output, constituting the input to stage 66. FETs 86 and 92 are thus turned on to earth FET 88 source; and FET 90 is held off. When # 2  turns on FET 88, the earth potential appears at the output. Any injection currents still reaching the substrate are at least partly " collected " by a P-type ring 98 around each stage. In the second arrangement, not using the FETs 76, 78 of Fig. 5, the first FET (126, Fig. 7, not shown) has its drain directly connected to the source of the second FET (128), and spikes on this interconnection are at least partly shorted out to prevent them injecting currents into the substrate by the diode (150) connected to earth. This diode is an alloy junction diode, or a Schottky diode, having a lower forward voltage drop than the P-N junctions of the integrated circuit, and also having a collection ring (164) to further reduce injected currents.
