Title: Torsional vibration absorbers
IPC: F16F15/14
Filed: 1951-11-20
Abstract: 686,976. Jointing by stamping. GENERAL TIRE & RUBBER CO. Nov. 20, 1951 [Nov. 30, 1950], No. 27212/51. Class 83 (iv). [Also in Group XXXII] A torsional vibration absorber comprises a wheel body 1 carrying a rim 3, an inertia member 7, and a rubber ring 8 held under radial compression between the rim 3 and the inertia member 7. Before assembly, the ring 8 is of toroidal form and of considerably less diameter than the external diameter of the inertia member. On assembly, the ring 8 is stretched on to the inertia member which is then pressed into position within the rim 3. The absorber is then placed, as shown, in position within the lower of a pair of dies 12, 16. The upper die 16 is bell-mouthed at 17 to co-operate with a spigot 15 on the die 12. The die 16 is tapered at 18 so that on movement towards the lower die it engages the rim 3 and deflects it, in order to apply radial compression to the ring 8. The absorber may be tuned by increasing the degree of compression of the ring 8 by spinning the rim 3 (by means of a roller) into closer engagement with the ring 8. A member 6 is secured to the wheel body to form a belt pulley.

Title: Compensator circuit
Inventor: HESTER FRANK ALLEN
IPC: H04N1/409
Filed: 1951-11-26
Abstract: 714,713. Copying telegraphy. FAXIMILE, Inc. Nov. 26, 1951, No. 27648/51. Class 40 (3). [Also in Group XL(c)] In a copying telegraph system, a waveform changing circuit is employed to introduce overshoot at each change of amplitude in the signal waveform whereby changes in graphic density of a transmitted picture are emphasized in the recording at the receiver. The invention results in a steepening of the slopes of the signal waveform thereby effectively compensating for aperture distortion and permitting the bandwidth of the transmission to be limited to the elemental frequency of the system. In one embodiment, Fig. 3, the signals from a source 6 are applied to the utilization device 9 via two valves 13, 17 feeding a common anode lead 27. The signals are applied to the grid of valve 13 directly and to the grid of valve 17 through a differentiating circuit 22, 23. By varying the setting of resistor 22 a controlled amount of overshoot may be introduced into the combined signal with a consequent steepening of the signal slopes. In another embodiment, Fig. 2 (not shown), the signals are applied across a differentiating network comprising a parallel CR circuit in series with a resistor, and the output signals are taken from across the series resistor. The value of the series resistor is made low compared with the reactance of the capacities at the highest frequency it is desired to compensate. In yet a third embodiment, Fig. 4 (not shown), the waveform is changed by means of a damped oscillation introduced by a low " Q " series tuned circuit connected in the anode of a valve stage to which the signals are applied. The output from the stage is taken from across the capacitor. The " Q " is made of the order of 2, and the circuit tuned to resonate at the elemental frequency of the system.

Abstract: 1,114,633. Hydraulic mould locking devices in injection moulding machines. BRODERNA AKESSONS MASKINFABRIK A.B. 21 June, 1966 [22 June, 1965], No. 27722/66. Heading B5A. [Also in Division F1] An injection mould is closed by an hydraulic apparatus comprising a cylinder 11 in which slides a piston 12 seated on a hollow piston rod 20 which slides on a tube 22, and a valve 18 sliding to close a central bore 16 on the piston, the area of the piston facing a space 11a facing a moving mould part support plate 10 being greater than an opposed area facing a space 11b and comprising the annular area of the piston around the rod 20, but smaller than the total effective area of the piston facing the space 11b i.e. the annular area of the piston around the rod 20 plus the area corresponding to the outer diameter of the pipe 22. To close the mould, an hydraulic passage 24 is closed, fluid being supplied via passages 25, 26 to the space 11b and the interior of the tube 22 respectively, there arising an excess pressure in fluid held in space 11a, which causes the valve 18 to slide rearwardly, thereby opening branch ducts 17 from the bore 16 and bleeding extra fluid to space 11b which initiates rapid closing movement of the piston 12, rods 14 thereon supporting the plate 10. To re-open the mould, fluid is pumped to space 11a, via passage 24, passage 25 is closed and passage 26 is connected with a reservoir. Fluid flows from the excess pressure in the space 11b, via ducts 17 to space 11a past the valve 18, rapid opening being effected, this opening ceasing when priming of passageway 24 is ceased.

Title: An improved means of dynamically balancing rotors
IPC: G01M1/04
Filed: 1950-11-14
Abstract: 686,205. Testing balance of rotary bodies. AVERY, Ltd., W. & T. (Schenck Maschinenfabrik Ges., C.). Nov. 14, 1950, No. 27741/50. Class 106 (ii). Means for dynamically balancing rotors comprises the provision of a pair of masses at each end of the rotor, the masses of each pair being radially movable on separate spindles disposed at right angles to one another. In Fig. 1, the masses 5 and 6 of a pair are mounted on screw spindles 7 and 8 spaced 90 degrees apart in planes transverse to the rotor axis, the spindles being offset from one another along the axis 4 by a short distance 4a. The spindles 7 and 8 have star-wheels 9 and 10 at their outer ends and these star-wheels can be rotated in either direction during the rotation of the rotor 1 by pushing the relative pins of a series of four pins 11a, 11b, 11c, 11d in fixed brackets 12, into the paths of the star-wheels. As the masses are not rotatable, rotation of the star-wheels 9 and 10 enables the masses 5 and 6 to be moved radially as desired in a manner enabling a rotor that has become unbalanced to be rebalanced by trial and error. Alternatively, Fig. 2, each star-wheel 9 and 10 may be replaced by a disc 13 passing between opposed magnets 14 during each revolution of the rotor 1. By sliding a selected magnet into a position such that the disc 13 passes through its field during the rotation of the rotor, the disc will be caused to turn and radially adjust the position of the mass on the spindle.

[Also in Division G1] Apparatus for detecting metallic objects in human or animal tissue comprises two electrical oscillators, a controlling coil for one of the oscillators being mounted in a feeler member, and automatic frequency control means, having a large time delay, which tends to keep the frequency of the other oscillator at a predetermined spacing from the first. An oscillator 2 is coupled with the search coil 1 and its output is passed through a frequency multiplier 3 and filter 4 to a mixing circuit 7 which also receives the output from an oscillator 5 through a filter 6. The beat frequency, which is preferably of the order of 400 c/s., is passed through a volume control 8 and amplifier 9 to an earpiece 10, so that if the search coil 1 is brought near to a metallic object the frequency of oscillator 2 is changed and the resultant change of output tone is apparent in the earpiece 10. In order to prevent the apparatus being influenced by large masses of metal in the vicinity of the patient, part of the output is passed through an amplifier 11 and counting device 12, 13, 14 to an automatic frequency control 15 which changes the frequency of oscillator 5 in such a way as to tend to maintain the original output tone constant. However, it does so with appreciable time delay so that although it corrects for large static metal masses, whereby they have no effect on the operation of the equipment, it does not influence the change in output tone resulting from the comparatively rapid movement of the search coil 1 in the vicinity of metal to be located. If the output frequency becomes so high that the circuit 12, 13, 14 cannot follow it, it passes through a high-pass filter 16 to actuate a relay 17 which applies to the A.F.C. circuit 15 a voltage of sufficient magnitude to restore the output to a frequency which the circuit 12, 13, 14 can accommodate.

Title: Method and apparatus for obtaining a constant luminous or thermic effect from a source of variable energy
IPC: H02P7/20
Filed: 1930-09-19
Abstract: 369,549. Photographic printing apparatus. CRAYSSAC, L., 17, Avenue Victor Hugo, SÞte, Herault, France. Sept. 19, 1930, No. 28047. Convention date, Oct. 19, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 98 (i) and 98 (ii).] In a method of obtaining a constant luminous or thermic effect from a variable source of energy, a member which is displaced by means actuated by the energy from the same source is arranged to cut off the supply of energy after it has undergone a predetermined displacement. In an apparatus as applied to photographic printing, a continuously running electric motor 1 drives a shaft 18, bearing a worm 19 which meshes with a gear 20 on the axis of which is a crank 30 which operates the contact 42, 43 after a definite number of revolutions of the motor 1. When the starting contact 58 . . 64 is closed the electromagnet 55 is energized bringing the switch 47 into the position shown and lighting the printing lamp 15 through the contacts 47a-49. At the same time the worm 19 is thrown into mesh with the wheel 20. After a predetermined number of revolutions of the motor the contact 42, 43 is closed, energizing the electromagnet 56, which reverses the switch 47, switching off the printing light 15 and lighting the red lamp 82. At the same time an arm on the switch 47 disengages the worm 19 from the gear 20. The time of operation of the motor is varied by the position of the flap 31, against which the crank 30 is pressed by the spring 22 when the worm is out of mesh with the wheel 20.
