Title: Electrolytic refining of silver
IPC: C25C1/20
Filed: 1974-09-23
Abstract: Silver is purified which contains copper as a significant impurity. In this process the electrolyte contaminated with copper is drawn off from the electrolytic silver purification cell and treated with an immiscible liquid phase which contains a selective complexing agent for copper ions. As a result, copper is removed from this electrolyte without the silver first having been removed. The electrolyte which after this treatment has a reduced copper content can again be used in the electrolysis for the purification of silver. It is possible to carry out continuously this process of drawing off, treatment and returning, so that the silver electrolysis takes place from an electrolyte which has an essentially constant copper content.

Abstract: 1,164,713. Controlling change-speed gears. REGIE NATIONALE DES USINES RENAULT, and SOC. INDUSTRIELLE ET COMMERCIALE DES AUTOMOBILES PEUGEOT. 11 Sept., 1967 [30 Sept., 1966], No. 41434/67. Heading F2D. Two sliding gear-wheels of a change-speed gear, each movable between a neutral position and a ratio engaged position, are moved by respective forks 14, 15 slidable on an axially movable shaft 13 and in bores 2 of a casing 1, simultaneous engagement of two ratios being prevented by interlocking means which allows only one fork at a time out of its neutral position. A ball 22 in a bore 20 of the sleeve of fork 14 engages either a recess 3 in the casing to lock the fork in neutral, or a recess 24 in the shaft 13 to lock the fork to the shaft. A spring- urged ball 17 in the casing is engageable with slots 16, 17 in the fork 14 sleeve to limit its axial movement, the ball being able to move between slots 16, 17 but not beyond them. The fork 15 has similar lock and stop arrangements. In the neutral position shown, circlips 26, 27 abut the ends m, n of the fork sleeves. When shaft 13 is moved rightwards, fork 14 is carried with it to engage a first ratio, a ball 8 preventing movement of fork 15, as does the ball 23 after initial movement. Similarly, if shaft 13 is moved leftwards, fork 15 is carried with it to engage a second ratio, fork 14 being locked in neutral. A stud 28 engages a flat 29 on the shaft to prevent rotation of the latter. The circlips may alternatively be between the forks, to abut their faces p, q.

Abstract: 1369553 Wheel slip control systems KELSEY-HAYES CO 7 Sept 1972 [13 Sept 1971] 41587/72 Heading G1N The slip of a vehicle wheel, as determined from either its deceleration or from a comparison of its angular velocity and the speed of the vehicle, is used to control the operation of a brake. As shown, two wheels of a vehicle, each with its brake shoe 28 and drum 30 operated by actuators 22, 24 and a controller 20, have speed sensors 32, 34 producing pulse trains at a frequency proportional to the wheel angular velocity. The frequencies are converted by integrators 36, 38 to voltages which are compared by transistors Q1, Q2. The lower voltage, representing the lower angular velocity, is fed to a circuit 50 which produces an output signal when excessive slip occurs to switch on transistor Q4 and switch off transistor Q5, thereby breaking the circuit through actuators 22, 24 and releasing the brake pressure. When excessive slip ceases Q5 is again made conductive and braking is restored.

Title: Improvements in or relating to magnetrons
IPC: H01J25/55
Filed: 1959-12-14
Abstract: 874,105. Magnetrons. WESTERN ELECTRIC CO. Inc. Dec. 14, 1959 [Dec. 29, 1958 (2)], No. 42422/59. Class 39(1). A magnetron -comprises a series of anode cavities defined by vanes 10 extending from a cylindrical anode 11, certain of the cavities being coupled by a non-uniform system of slots 12 to an annular resonator 35. The resonator 35 is dimensioned to operate in the TE 011  mode and is coupled to alternate ones of the inner cavities. The voltages on the vanes of the uncoupled cavities are provided by mutual Inductance, resulting in a 180 degree phase difference between alternated vanes. This is the proper condition for maintainance of the # mode of oscillation within the inner system. The frequencies of the inner and outer resonant systems are different, the latter being independently adjustable by means of a tuning ring 49. The slots 12 themselves form resonant circuits and if all the slots are similar a uniform "slot mode" pattern tends to propagate around the anode 11 and to interact with the electron stream. To prevent this, the slot system is made non-uniform e.g. by randomly omitting some of the slots, providing slots of random length or by joining together groups of two or more slots by transverse slots 55, Fig. 3, whereby the phase shift between connected slots is reduced to zero. A further method consists in dividing the slots into alternating groups 52, 52<SP>1</SP> and 53, 53<SP>1</SP>, Fig. 5, the slots in groups 52, 52<SP>1</SP> being shaped to decrease their capacitance and those of groups 53, 53<SP>1</SP> being shaped to increase their inductance. Alternate groups of narrow and broad slots give a similar effect. It is stated that grouping of similar slots prevents undesirable bunches of electrons from persisting throughout their path. Further suppression of slot modes may be obtained by loading the ends of the slots with dissipative rings. Spurious modes within the outer resonator 35 may be suppressed by means of a dissipative element 38 at the end of a choke slot 36. The resonator is coupled to a glass-filled output guide 41 by means of a slot 40. The magnetic field of the magnetron is provided by polepieces 15, 30 suitably apertured to accommodate cathode 16. The tuning ring 49 is linked by means of members 46, 47 to the usual screw and bellows mechanism 45, 50.
