Title: Improvements in variable speed gears
IPC: B60K17/08
Filed: 1944-08-25
Abstract: 597,814. Variable-speed gearing. CLUTTON, C., and EDISBURY, J. R. Aug. 25, 1944, No. 16186. [Class 80(ii)] Relates to variable-speed gearing comprising a plurality of epicyclic trains in series each train having a member which can be braked or clutched frictionally to a member of an adjacent train and in which different groups of gear ratios may be chosen from the wide range available, the ratios of any particular group selected being made operative by movement in a gate of a normal type of gear change lever. According to the invention the spacing of the gear ratios of one group varies from the spacing of another group. As shown, a gear comprising three epicyclic trains in series has six electromagnets 1a-6a, for actuating the clutches and brakes. Any three of the electromagnets are always energised at one time for any particular gear ratio. The mechanism provides eight gear ratios. For three groups of four ratios, three arms 8, Fig. 3, movable by a lever 7 can each engage any one of three contacts 9 connected to a block of eight solenoids 11. Each solenoid 11 controls the circuits of three electromagnets through triple contact switches. The arms 8 and the solenoid 11 corresponding to the high speed ratio which is thus in each group, are connected at b to the H gate 10 of the speed change lever. Thus four speeds are available by moving the gear lever in the gate 10. A change in the position of the lever 7 will provide a different group of four speeds at the gate 10. In Fig. 3, the numbers in brackets adjacent each solenoid indicate the gear ratio obtained when that solenoid is energised. In a modification the gear change lever may take an additional position adjacent the top gear position to provide an overdrive ratio. The invention may be applied to two or more gear boxes in series. The gear selecting means may be electric, hydraulic, pneumatic, electro - hydraulic, electro-pneumatic or mechanical.

Title: Improvements relating to evacuated devices and methods of exhausting the same
IPC: H01J7/18
Filed: 1924-07-07
Abstract: 238,664. Cachemaille, A. S., (Westing- house Lamp Co.). July 7, 1924. Drawings to Specification. Vacuum tubes.-A method of evacuating a discharge tube consists in vaporizing magnesium within the tube, after the pressure has been lowered to a predetermined value, in order to clean-up the residual gases, and in maintaining a potential difference between the anode and the -cathode of the tube sufficient to ionize the residual gases and facilitate their clean-up by the vaporized magnesium. The method is applicable to the manufacture of tubes having oxide-coated cathodes. After the bulb of a tube has been sealed and the magnesium vaporized, the cathode, which is coated with barium carbonate and strontium carbonate, is heated to drive off the carbon dioxide. The potential difference between the anode and the cathode ionizes the carbon dioxide and absorption of this gas by the mirror of magnesium is facilitated.

Title: Improvements in or relating to brake control devices
IPC: B60T8/18
Filed: 1945-06-29
Abstract: 594,215. Brakes. BUDD WHEEL CO. June 29, 1945, No. 16598. Convention date, Aug. 31, 1944. [Class 103 (i)] In a fluid pressure braking-system having means responsive to wheel slip for releasing pressure from the brake cylinder and maintaining the release for a time sufficient to allow the wheel to return to vehicle speed after slipping, safety means are provided which cut out the pressure release means if the said time has been appreciably exceeded without cut-out of the release means being normally effected, the control of the brake cylinder being thus restored to the operator. As shown, the invention is applied to a slip-control system substantially as described in Specification 586,287, the inertia-operated switch 10 being in series with a magnet coil 13 which, when energized, closes a mercury switch 16 in a secondary circuit 17 having parallel branches 18, 19 the latter branch including a solenoid 20 and a switch 21. The switch 21 is normally closed and, when the switch 16 also is closed, the solenoid 20 operates the valve 3 to connect the brake cylinder 1 to the 'exhaust port 8. Time lag in the opening of the mercury switch allows the wheel to return to a non-slipping speed before the brake cylinder is again connected, by the de-energization of the solenoid 20, to the operator's control pipe 2. If a short circuit occurs in either the circuits 11 or 17, the valve 3 would be held open continuously. To enable the operator again to take control of the brake cylinder, means are provided for opening the switch 21 after say 10 seconds from the closing of the circuit 16. These means comprise a solenoid 27 which is always energized, when the switch 16 is closed, to operate an armature 28, link 34 and sliding rod 25, the latter having a head 26 which ultimately engages a contact member 22 and opens the switch. The time taken to open the switch 21 is controlled by adjustment of the valve 42 of a dash pot 39, and when by opening the switch the operator's control is restored, a signal 45 is given to him by closing the contacts 46. If conditions in the circuits 11, 17 become normal, the solenoid 27 is de-energized and the switch 21 closes, a quick return being permitted by a one-way valve in the dash pot piston 40. In a modification, the member 22 and soring 24 are replaced by a pivoted contactor connected to a tension spring which passes from one side of the pivot to the other, so that the contactor is held by the spring in both the " open " and " closed " positions. When the contactor has been placed in the " open " position, it must be re-set manually to the " closed " position.
