Abstract: 560,379. Variable speed gearing; clutches. HOBBS, H. F. Sept. 23, 1942, No. 13365. [Class 80 (ii)] A layshaft type of gear-box having at least two gear wheels permanently in mesh with two other gear wheels includes at least three dog clutches each actuated by a piston subjected to fluid pressure against spring action, so that at least three different gear ratios are obtainable by the actuation of the different clutches. As shown, the gear-box is similar to the gear box shown in Fig. 22, of Specification 549,988, and comprises an input shaft C having a gear 401 meshing a gear 451 fixed on a layshaft, and an input shaft D having a gear 402 meshing a gear 456 loose on the layshaft. Gear wheels 430, 431, loose on the output shaft F mesh with gears 457, 455, respectively loose and fixed on the layshaft. Members 405, 406, fixed to the output shaft F and a disc 452 fixed to the layshaft have clutch parts so that the loose gear wheels may be clutched to their respective shafts. All the clutches are similar to one another. The gear 431, Fig. 3, houses an annular piston 442 having teeth 418A engaging axial splines in the gear 431 and clutch teeth 441 engageable with clutch teeth 440 on the member 406. Clutch disengaging springs 501 act between the piston 442 and a floating ring 503, and light springs 453 between the ring 503 and a baulk ring 500 urge the latter into frictional contact with the member 406. The baulk ring 500 has three arms 51 engaged in slots 52 in the piston 442. Each slot 52 has a part 552 and a smaller part 553 connected by inclined steps 554, 555, and the arms 51 have corresponding inclined surfaces 556, 557. When, under fluid pressure, the piston 442 moves towards the clutching position, then, if the parts 406, 442, are not synchronised, one of the surfaces 556, 557, engages a step 554 or 555 and further movement of the piston is prevented by the baulk ring. When the parts 406, 442, are brought into synchronism the arms 51 drop into the small parts 553 of the slots 52 and the clutch teeth 440, 441, then engage without shock. The teeth 441 are inclined on one side so as to prevent engagement, or to be forced out of engagement, should another set of clutch teeth fail to disengage. The shafts C, D, carry clutch plates 12, 16, respectively, so that either may be clutched to an engine shaft A. The clutches are actuated by fluid pressure which acts on pistons 20, 24. Reference has been directed by the Comptroller to Specification 549,988.

Filed: 1940-08-29
Abstract: 542,424. Secret transmission. GENERAL ELECTRIC CO., Ltd., and BLOCH, A. Aug. 29, 1940, No. 13609. Drawings to Specification. [Class 40 (iv)] Speech or other signals originally occupying the band f 1  to f 1 <SP>1</SP> are increased in frequency by f o  cycles and are mixed with noise or irrelevant signals lying mainly within the original signal band, after which the mixture modulates a high-frequency carrier, the carrier and preferably both side-bands being transmitted. f o  preferably lies between f, and f 1 <SP>1</SP> and may vary cyclically with time. In reception, the signals are separated after detection by the use of a high-pass filter having a suitable cut-off and are transferred back to the original band. When f 0  varies, its instantaneous value is made available at the receiving end by the transmission of a pilot of a frequency that is a multiple or sub-multiple of f 0 . In the latter case, the pilot will fall within the noise range, and it may even constitute the whole of the noise. In an example, f 0  varies between 1,000 and 2,000 cycles, and the pilot frequency may be one-half or four times f 0 . Specifications 363,904, 516,088 and 526,483 are referred to. Reference has been directed by the Comptroller to Specification 526,483.

Filed: 1955-12-19
Abstract: 845,850. Circuits employing bi-stable magnetic elements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 12, 1956 [Dec. 19, 1955], No. 13692/59. Divided out of 844,850. Class 40 (9). A P-pulse generator circuit or ring counter comprises cores C1- C47 which provide pulses in turn at outputs 1-47, bore C1 only is initially in state 1, and this state is stepped along the cores by alternate O driving X and Y pulses, the reversal of any core from state 1 to state 0 causing an associated transistor TA1-TA47 to conduct and set the next core to state 1. The arrangement includes a resetting circuit comprising cores CAS, CBS and associated transistors TAS, TBS which ensures that all the cores are in state 0 before a 1 state is introduced at core Cl. The. resetting circuit is controlled by clock and Z pulses which have a repetition frequency twice that of pulses X and Y and are alternately effective. In operation, core CAS is driven to state 1 by the clock pulses, while core CBS is driven to the same state each time a transistor TA1-TA46 is conductive. The Z pulses restore the CAS and CBS cores to state 0, and outputs are produced over transistors TAS, TBS which act ineffectively in opposition in a 1-driving coil on core C1. When the count reaches core C47, the core is able to change from state 1 to state 0 without driving CBS as the transistor TA47 is disassociated from the latter core. Core CAS alone produces an output on the next clock pulse, this single output being effective to restart the count by setting C1 to the remanent 1 state.

Title: Improvements in or relating to the recovery of precious metals from ores or preciousmetal bearing deposits
IPC: C22B11/08
Filed: 1935-05-14
Abstract: Precious metals are recovered from ores by extraction with dilute alkaline cyanide solution, subjecting the solution to a conditioning operation which renders the solution capable of actively reacting with a metallic precipitant, deoxides the solution, and neutralizes alkalinity to an extent sufficient to afford a pH value of from 6-8,4, and then contacting the solution with a metallic precipitant such as zinc or iron.  The conditioning operation may comprise the addition of sodium or calcium bisulphite, sulphur or carbon dioxides, either singly or in combination, a suitable source of mixed dioxides being flue-gas.  Before the addition of bisulphite, the solution may be neutralized with sulphuric acid and the bisulphite may be formed by interaction between the alkali or alkaline earth ion in the solution and sulphurous acid.  Reference has been directed by the Comptroller to Specification 442,315.
