Abstract: 529,560. Cathode-ray tubes. ARDENNE, M. VON. June 3, 1939, No. 16380. Convention date, June 3, 1938. [Class 39 (i)] [Also in Group XXXVI] In a cathode ray osillograph a very small recording spot-of the order 10<SP>-3</SP> mm-is obtained by first reducing the beam by diaphragms 3, 5, Fig 1, and then using a final short focus magnetic lens 7, the deflecting coils or plates 10, 11-which receive the measuring impulses-being mounted in a recess in the permanent magnet; a further diaphragm 6 with an aperture of 0.1 mm diameter is mounted in the magnet. With a grain size in the photographic film of 10<SP>-3</SP> mm the size of the spot is 5 X 10<SP>-3</SP> mm. The cathode ray gun deflecting and focusing means are mounted in one chamber communicating with another containing the film drum 9 &c. only through the aperture in the diaphragm 6, this being sufficiently small to enable different vacua to be maintained in the two chambers, the pressure in the chamber having the drum 9 being lower than that in the other chamber. The drum carrying the recording film or the final focusing system is movable laterally to give a long oscillogram. To enable the focusing of the spot to be effected the drum carries a prism 13 having a fluorescing screen 14 ; optical means 15, 16, 17 enable the trace of the spot on the screen to be observed. The beam may be projected through a Lenard window on to the recording means ; or the beam may impact a fluorescent screen which acts on a photographic film. Three oscillograms may be obtained simultaneously by using three deflecting systems 20, 21, 22, Fig. 3; a common magnetic focusing device is used and screening shields 23-26 surround the deflectors. In a modification separate deflecting systems are carried in independent pole pieces by a common main part.

Title: Improvements in hydraulic power transmission systems
IPC: B23Q1/00
Filed: 1941-12-20
Abstract: 546,879. Hydraulic power transmission. VICKERS, Inc. Dec. 20, 1941, No. 16444. Convention date, Sept. 30, 1940. [Class 69 (ii)] A hydraulic power circuit which is especially applicable for operating machine tools to cause a rapid advance of the tool followed by a slower feed motion and then by a rapid return and a final stop is so arranged that a hand control is provided in addition to an electric control for effecting the above sequence of operations, the hand control being capable of advancing the tool at a slow rate and permitting return at a rapid rate. The tool slide 44 is actuated by a piston 40 which is moved by liquid supplied by a pump 10 under control of spool valves 84, 86, Fig. 2, operable by the solenoids 112, 114 of electromagnets 60, 62 the energization of which is controlled by the switches 54, 56, 58, 68, 66, 72 shown in Fig. 1. On operation of a starting switch 68 both electromagnets are energized and the valves 84, 86 are raised and the pump supplies liquid at a rapid rate to the upper end of the cylinder 38 and the slide 44 descends rapidly until a cam 52 opens a switch 58 and de-energizes the magnet 62 thus permitting fall of valve 84 and causing the liquid to pass through a throttle 124 and to be under the control of a hydrostatic valve 122, so that the motion of the tool is slowed down. At the end of the down stroke a dog 50 on the slide operates a switch 56 which causes energization of magnet 62 and de-energization of magnet 60 and the reversal of valves 84, 86 causes a rapid return of the slide 44, until finally the opening of switch 54 stops the flow by the de-energization of magnet 62. The solenoids can be raised one at a time by hand manipulation of a lever 130 normally kept in neutral position by a spring 140. The pivot of lever 130 is provided with a hexagonal extension for engagement by an operating-handle, and the motions of the lever can set the valves for advance of the tool at feed rate only but for a rapid return. The main current is switched off during hand manipulation.

Patent GB-586744-A (GB)
Title: Improvements relating to operating mechanisms for change speed gears
IPC: B62M25/04
Filed: 1944-09-02
Abstract: 586,744. Variable-speed gearing. ALBION ENGINEERING CO., Ltd., and HILL, W. H. Sept. 2, 1944, No. 16770. [Class 80 (ii)] Relates to change gear operating mechanism wherein a gear selecting shaft 1, rotatably housed within the gear box 3, is adapted, when turned about its axis by a gear selector lever 2, to select any one of three or more speed ratios, and when positioned intermediate its bottom and second gear selecting positions to be in the neutral position. According to the invention, the gear-selecting lever 2 and a neutral selecting lever 8 are pivoted about separate fulcra, that of the lever 8 being co-axial with the shaft 1, the lever 8 and shaft 1 being so inter-connected that, as the gear lever 2 is actuated to move the shaft 1 from its neutral position to cause a change to a higher gear ratio, the lever 8 moves with the shaft 1, and subsequent displacement of the lever 8 against a stop 14 returns the shaft 1 to its neutral position. As shown, a bush 6 fixed to the shaft 1 is surrounded by the hub of the lever 8. A pointer 7 on the bush 6 passes through a slot 10 in the hub, the circumferential width of the slot being greater than that of the finger. A bolt 12 and springs 13 hold the parts together and prevent rattling. In the neutral position, Fig. 2, the lever 8 abuts the adjustable stop 14. The lever 2 is arranged so that after each operation it returns to a central position. Upward movement of the lever 2 will cause clockwise movement of the shaft 1 and bring in the lowest speed ratio, the slot 10 permitting this movement. Successive depressions of the lever 2 will bring in the higher gear ratios, during which operations the finger 7 will move the lever 8 anticlockwise away from the stop 14. Whatever gear ratio, other than the lowest, is in operation, depression of the lever 8 against the stop 14 will bring the gear to the neutral position.
