Title: Electro-mechanical apparatus for supervising and controlling the relative movements of two parts of a machine
IPC: H02P5/50
Filed: 1959-02-19
Abstract: 908,174. Automatic speed control systems. BUDNICK, G. A. A. Feb. 19, 1959 [Feb. 24, 1958], No. 5757/59. Drawings to Specification. Class 38 (4). In a machine tool, the shaft driving a cutter and the shaft driving a workpiece are each provided with graduated discs associated with photo-electric or other scanning devices delivering trains of pulses through two separate channels. The pulses in one channel are passed through a frequency divider, the other pulses being passed through a multiplier, so as to afford an order of relationship between the pulse trains suitable for comparison. The modified pulses are applied to a frequencycomparator which provides an error voltage for controlling the speed of one of the shafts. In a hobbing machine, compensation for speed deviations between the shafts is effected by an electric motor which is supplied with the error voltage and which is coupled through differential gearing to a variable gear transmission for the hobbing shaft. The electric motor may be replaced by electro-mechanical or hydraulic drives. In another arrangement, the correction is effected by the use of a dynamo-electric machine whose rotor is positioned in accordance with the error voltage. Alternatively, the machine may have two concentric tables coupled across an annular gap by rods of magnetostrictive or piezo-electric material, each rod being surrounded by a coil energized by a control voltage. Variations in the lengths of the rods cause the relative positions of the tables to be adjusted, Fig. 3 (not shown). Instead of adjusting the table, a cutter may be shifted in an axial direction by means of a magnetostrictive or piezo-electric element. A number of pulses may be added to or subtracted from the train of pulses associated with the cutter shaft, these further pulses being derived from a frequency divider which is adjusted in accordance with the angle of slope and the cutter feed. Rotational adjustment may be effected alternatively by shifting the scanning point of the disc on the cutter shaft, Fig. 4 (not shown). In an arrangement for measuring toothed wheels, a gauge wheel is engaged with a wheel to be tested, the gauge wheel being driven and the other wheel being braked to simulate known operating conditions. Graduated discs and scanning devices are associated with each wheel, and frequency dividers for the two pulse trains are adjusted in accordance with the number of teeth of the appropriate wheel. A comparator provides an error voltage which indicates the hobbing deviation, Fig. 5 (not shown). A frequency multiplier which is set to the number of teeth of the gauge wheel, and a frequency divider which is adjusted to the number of teeth of the wheel under test may be connected in one of the pulse channels, Fig. 6 (not shown).

Title: Multiple electric mercury switch device
IPC: C23C8/00
Filed: 1958-02-28
Abstract: 873,075. Mercury switches; stencil switches. EVANGELISTA, J. Feb. 28, 1958, No. 6504/58. Class 38 (5). A switch comprises a vessel containing mercury, a number of contact-containing channels connecting with the vessel, a perforated pattern member which is operable to selectively seal or unseal portions of the channels, and means for causing the mercury to flow into unsealed channels to engage the contacts therein. In one form, Figs. 1, 2, the channels 17 are formed in a block 16 and run into the vessel 14 which is connected to a flexible mercury-containing tube 30 fixed to a crank 33 on a shaft 26. The latter, which is rotatable by a lever 27, has cams 28 bearing on a plate 20 pivoted at 22 so that a pattern member (not shown) may be clamped between rubber facings 24, 25 on the block 16 and plate 20. The plate 20 has channels 20a open to atmosphere and coinciding with the channels 17. Thus the pattern member will block some of these channels 20a from channels 17 and when the tube 30 is raised to the dotted position, Fig. 2, by the crank 33, mercury will be able to flow only into the unsealed channels to bridge contact pairs 19. In a modification, Figs. 4, 5 (not shown), the mercury is forced into the unsealed channels by the compression of a bellows by a cam on the shaft 26. In a further arrangement, Fig. 6, the lower ends of the channels 17 are sealed, after the mercury has moved into them, by a rubber plate 43 which is moved upwards when the centre part of a blade spring 44 is forced upwards by the downward movement of its ends by plungers 48 operable by cranks 51 on the shaft 26. The spring 44 bears on pivot-points 47 and when it bends its centre pushes a plate 42 and the plate 43 upwards. In Fig. 9, the channels 56 are formed in a block 55 mounted on a resilient cup member 51 resting on a solid base 50, the cup member having intermediate walls 71 separating the channels. When a pattern member is placed between block 55 and a further block 64, and the latter is depressed by a cam, the cup 51 is squashed and mercury forced up into the unsealed channels, it being maintained by the engagement of the lower faces of block 55 with the bottom wall of the cup 51. In a modification of this arrangement, Fig. 10, the base 75 has upstanding walls 76 forming receptacles into which are inserted walls 79 on a block 78, which thereby split the receptacles into channels 80. The block 78 and base 75 are separated by a resilient member 82 which allows the block to be depressed by a cam acting on a further block 86, the pattern member being sandwiched between blocks 78, 86. The mercury is maintained in its raised position by the engagement of the walls 79 with rubber elements 84 in the base 75.

Abstract: 1387873 Quadraphonic decoders CBS Inc 11 Feb 1972 [24 Feb 1971] 6580/72 Heading H4 In a quadraphonic reproducing system for feeding loud-speakers at the four corners of a listening area with respective signals derived by a matrix, Fig. 1A, from two channel signals 10, 12, each comprising a respective predominant front signal R f  or L f  together with sub-dominant rear signals, R b  and L b , of both sides in quadrature with different signals leading in each channel, and in which the matrix derives respective loud-speaker signals each having a predominant component L b , R b , L f  or R f , together with subdominant signals of both sides, from the front if the predominant signal is from the rear, and vice versa, the signals are fed to the loud-speaker via amplifiers 100, 102, 104, 106, whose gains are controlled via a logic circuit, Fig. 1B, which is fed with signals derived from points in the matrix providing two pairs of signals, one pair containing sub-dominant rear components which are directly in phase, or in phase opposition, in the two signals while the other pair have subdominant front components in phase, or in phase opposition in the two signals. The signals in each pair are full wave rectified at 36, 38, 40, 42, and the two signals in each pair are compared in comparators 60 and 62. If only the rear signals L b  and R b  are present the inputs to comparator 60 will be equal and no output will result, while an output will be obtained, provided the L b  abd R b  signals are uncorrelated, from comparator 62. The comparator outputs are full wave rectified at 64, 66, fed through shaping networks and applied to control circuits 80, 82, which differentially adjust the gains of the amplifiers feeding the rear speakers relative those feeding the front speakers. Similarly if only the front signals L f  and R f  are present the gain of the amplifiers feeding the front loudspeakers is increased and that of the others reduced. An alternative form of matrix, the same as that of Specification 1,379,771 and a suitable logic circuit are described with respect to Fig. 4A and 4B (not shown). (For Figures see next page.)

Title: Lactam polymerization process
IPC: C08G69/00
Filed: 1964-02-19
Abstract: In the anionic polymerization of C6 and higher lactams the time of the viscous range (between the onset of viscosity increase and reaching a viscosity too high for pourability) is increased by using at least two promoters selected to activate the polymerization at different temperatures, one being effective at least 20 DEG  C. lower than any other and being used in an amount insufficient by itself to enable the polymerization to go to completion.  Various lactams, catalysts and promoters are mentioned. The only specified combination of promoters is octadecyl isocyanate (105 DEG  C.) and tolylene diisocyanate (155 DEG  C.).
