Title: Improvements in epicyclic gearing
IPC: F16H61/02
Filed: 1920-08-09
Abstract: 170,434. Lander, T. E. Aug. 9, 1920. Variable-speed epicyclic gearing of the kind in which the driving.wheel of a train drives the driven wheel through planet gearing and in which the variations of load on the driven shaft control a brake acting on the driven wheel, comprises means for operating a brake adapted to turn with the planet carrier. In the form shown in Fig. 1, two trains in series are employed, each comprising an eccentric planet gear 22 meshing with a driving sun gear 21 and a driven internal gear 27. The trains are normally constrained to turn solid on top speed by brake segments 41, Figs. 2 and 3, thrust inwards by springs 46 upon drums 28 secured to the gear rings 27. As the load on the driven element 34 increases, the segments 41 are separated to allow epicyclic action, and therefore reduced speed-ratio, by cams S2, Figs. 1 and 9, acting on radial plungers 49. The cams 52 turn with eccentrics 25, which carry the planet gears, and the plungers 49 ride up on the cams while revolving with them. Projections 48 from the brake-carrying elements have radial openings in which slide dogs or detents 53, Fig. 4. During high speed, these, detents 53 fly outwards and are inoperative. As the speed falls owing to continued increased load, springs thrust the detents 53 inwards until they catch on fixed ratchet teeth 54, bringing a definite low speed into action- Hand operation may supplement the automaticaction. The gear train 34, 35, 37, 38 is for reversed driving. Other forms of epicyclic train may be adapted to the invention. Specification'. 141,427 is referred to in the Provisional Specifica-- tion.

Title: Method of making inlaid electrical circuits
IPC: H05K3/20
Filed: 1954-08-12
Abstract: 751,445. Printed circuits. PRITIKIN, N. Aug. 12, 1954 [Aug. 17, 1953], No. 23413/54. Drawings to Specification. Class 36. An inlaid circuit is made by chemically cleaning one surface of a metal sheet in a desired circuit pattern, the remaining portions of the surface being protected by a non-conducting resist, electrolytically applying a metal different from that of the sheet to the clean surface, applying insulating material in plastic form thereover and removing the metal sheet by means of a solvent which is substantially inert towards the materials of the circuit. The resist may be applied to a copper base as a photosensitive coating which is exposed to the negative pattern of the circuit, developed and fixed so that the non-exposed portions are washed away. After cleaning in sulphuric acid, silver is electrolytically deposited on the exposed portions of the base, the reverse side of the base being suitably coated to prevent deposition thereon. The remaining parts of the resist may then be removed with an organic solvent which does not harm the copper base in the deposited silver. Polystyrene or Teflon is applied over the treated surface and pressed to ensure firm and uniform contact, after which the copper base is removed by an aqueous solution of ferric chloride. The resins may be applied to the base by printing, rolling or screening and, if it is compatible with the insulating material it need not be removed after the electrolytic process. Various metals may be used for the base sheet and conducting pattern, the solvent for the base being selected accordingly. Specification 639,178 is referred to.

Abstract: 1,182,284. Automatic control. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. May 22, 1967 [May 24, 1966], No.23679/67. Heading G3R. A measured value of a process variable is compared with a set value and the difference applied as a D.C. signal to a capacitive feedback integrating amplifier so that when the integral reaches a predetermined value it resets the integrator and produces a corresponding step change in a memory device correcting the process variable. In Fig. 1, a voltage dependent on the difference between set and measured values of a process variable is applied to terminals 1, 2 of a potentiometer 3 the output of which is applied through a proportional amplifier 14 and a summing amplifier 18 to correct the process variable. The output of potentiometer 3 is also applied to summing amplifier 18 through an amplifier 5 having a feedback capacitor 6 so that an integral component of control is added. When the integrated signal reaches a predetermined value in either sense, a trigger device 7, e.g. a thermionic value relay, operates to discharge condenser 6, e.g. by switching or by discharge pulses applied through a diode circuit, so that the integrator is reset to its datum condition. At the same time, trigger 7 operates a stepping motor 9 to adjust a potentiometer 10 by one step in a corresponding sense so that the integration is, in effect, stored by the potentiometer, the output of which is applied to summing amplifier 18 to replace the signal removed by resetting the integrator. Integration can thus take place step by step over long periods. The Specification also refers to adding a differential component, electro-pneumatic conversion of signals, and automatic correction by adjusting the set value of a further controller.
