Patent GB-560238-A (GB)
Title: Improvements in or relating to machines for copying and reproducing
IPC: B23Q35/18
Filed: 1942-09-23
Abstract: 560,238. Milling-machines. BRISTOL AEROPLANE CO., Ltd., BOLAS, J. T., and EDWARDS, R. W. Sept. 23, 1942, No. 13412. [Class 83 (iii)] A copying or reproducing machine having a tracer coacting with a former to limit relative movement between the cutter and the work, particularly in the manner described in Specification 417,709, has power means for reciprocating or oscillating the work carrier and former and means for reversing the direction of movement of the work and former brought automatically into operation when the former engages the tracer. In place of the slipping friction device for oscillating the work and former described in Specification 417,709, the work head 11 is oscillated by a hydraulic - cylinder 15 acting through an arm 12. A pump 18 delivers through a line 29 to a pilot valve 19 and a reversing valve 22 connected through lines 32, 33, and valves 46, 47, of the feed mechanism described below to opposite ends of the cylinder 15: The pilot and reversing valves are controlled by excess pressure valves 24 which move upwards against springs 26 when the pressure beneath the valve pistons exceeds a predetermined value. In the position shown, in the Figure, fluid passes into lines 32, 49 to move the piston 17 to the left thus oscillating the work and pattern head. If the tracer engages the pattern the movement is arrested and consequent build up of pressure in lines 32, 41, causes the left-hand excess-pressure valve 24 to lift, thus allowing flow to line 35 to shift the pilot valve to the right. This causes flow through lines 29, 31, to the left of valve 23 which moves to the right and allows flow to lines 33, 48, to return the piston 17. The feed mechanism indicated at 55 is operated from a cylinder 43 controlled by a valve 45 which is operated by fluid from the cylinder 15. The valves 46, 47, are raised by the normal pump delivery pressure but as soon as, say, the lefthand end of a cylinder 15, is cut off from pressure fluid by movement of the reversing valve the valve 46 falls to the Figure position and fluid escaping along line 48 first reverses the valve 45 and then passes to exhaust 57. Pressure fluid from the pump now passes to line 53 and operates the feed piston the feed movement occurring immediately after each oscillation, or each alternate oscillation. In some cases, as when cutting ports in sleeves instead of cylinder barrels, the traversing movement is timed to occur at the end of an oscillatory movement. In this form when pressure build-up occurs in line 32 on account of the arrest of piston 17 the excess pressure valve is opened and pressure admitted to operate the piston of feed cylinder 43 before permitting flow to operate the pilot valve 21.

Title: Military Shield.
Inventor: NICHOLSON ALEXANDER
IPC: F41H5/14
Filed: 1916-09-21
Abstract: 109,124. Nicholson, A. Sept. 21, 1916.

The ring C may be fitted with a grooved or studded tyre K, Fig. 5, which may be in sections held together by lugs and bolts on the inside; or it may be made endless, in which case the inwardly-projecting studs shown in Fig. 5 are replaced along one edge by screws to allow of assemblage over the ring C.
Patent GB-1573846-A (GB)
Title: Display devices
IPC: G09F13/18
Filed: 1977-03-31
Abstract: The display device has a normally totally reflecting presentation surface which can be brought into optical contact at freely selectable matrix points with an element (4) which has a coating (9) on its side facing the presentation surface. The contact is such that total reflection no longer takes place at the contacted matrix points. Contacting is controlled electrically via an electrode system. The presentation surface belongs to a fluorescent plastic plate (5), which is mirrored on its end faces and acts as a light trap for the fluorescent light. The coating (9) of the element (4) is designed to scatter light. The optical contacting is performed via a contact film (10), so that at the optically contacted matrix points the fluorescent light exits from the fluorescent plate (5) by deflection or scattering on the coating (9). Such a display device consumes little power, is simply constructed and yet produces high-contrast images. The high presentation qualities are based essentially on the fact that the ambient light is collected by the plastic plate (5) on a large surface and is coupled out again on small surfaces at an increased intensity. <IMAGE>

Patent GB-611816-A (GB)
Title: Improvements in or relating to switch devices comprising an auxiliary relay and a principal relay
IPC: H05G1/38
Filed: 1946-05-09
Abstract: 611,816. Switching systems for consumption apparatus. PHILIPS LAMPS, Ltd. May 9, 1946, No. 14027. Convention date, Feb. 18, 1942. [Class 38 (iv)] [Also in Group XXXVII] A switching system, particularly for use with X-ray or welding equipment and for automatically ensuring the closure of one or more auxiliary circuits a predetermined time before the closure of a main circuit which is subsequently opened after the passage of either a predetermined quantity of energy or time, comprises a relay 21 for the main circuit 31, 32, controlled through a delay circuit by an auxiliary relay 1 having contacts controlling the auxiliary circuits, the energizing circuit of the last relay including contacts 29, 30 which are temporarily opened, to ensure de-energization of the auxiliary circuits, whenever the first relay is opened. The main circuit may be the high-tension supply circuit for an X-ray tube and the auxiliary circuits those for supplying heater current and current for rotating the anode. The delay circuit comprises a thyratron 15, the anode circuit of which includes the winding of relay 21 and which is energized from a pulsating D.C. source 20, the grid circuit including a timing condenser 9, associated resistor 11 and battery 10. Timing of the exposure is by a circuit 26-28 which deenergizes relay 21. To initiate an exposure, press-button switch 8 is operated, thereby energizing, over normally closed contacts 29, 30 of relay 21, the winding of relay 1 which, on picking up, holds in over contacts 5, closes the auxiliary circuits over contacts 3, 4 and removes a short-circuit from condenser 9 at contacts 6. The condenser voltage rises and eventually overcomes a hold-off bias 13 previously applied to a grid 14 of the thyratron which then conducts and energizes relay 21 from the pulsating source 20. Relay contacts 22, 23 in the main circuit, close and the tube is energized, auxiliary contacts 19 of this relay simultaneously opening to remove a short-circuit on the tuning condenser 26. The condenser voltage rises and eventually overcomes a " turn-on " voltage 17 on another grid 16 of the thyratron which then becomes non-conducting and de-energizes relay 21. A spring 25 returns the relay contacts to their initial positions, Fig. 2, to terminate the exposure, momentum, however, temporarily separating contact 29 from contact 30, which is carried by a pivoted arm, and so interrupting the holding circuit of the auxiliary relay which then drops out. In another construction, contact 29 is carried at the free end of a flexible strip fixed at the other and the armature of relay 21 is arranged to strike an extension of the arm carrying contact 30 to cause temporary separation of the contacts.
