Title: A new or improved safety device for the retractable undercarriages of aircraft
IPC: B64C25/22
Filed: 1940-05-06
Abstract: 538,700. Retractable aircraft undercarriages. TURNER MANUFACTURING CO.. Ltd., and CAREY, F. H. May 6, 1940, No. 8076. [Class 4] [Also in Group XXIX] The retraction mechanism of an aircraft undercarriage is controlled so that retraction can only be effected after the aircraft has reached a pre-determined flying speed. As applied to hydraulically operated retraction mechanism the control device is inserted in the main pipe lines 2, 3 to the jacks 4, 5 and co-operates with an air speed responsive device comprising a capsule 25, Fig. 2, connected to the pressure side of the pitot head 9 of the air speed indicator 10, housed within a hermetically sealed box 24 connected to the static side of the pitot head, sufficient expansion of the capsule completing an electric circuit including a solenoid 17, Fig. 1, which controls the movable element of the control device. This comprises a plunger 1 with waisted parts 19, 22 and 18, slidable within a body 11 having two pairs of pipe connections 13, 12 for connection to the pipe lines 2, 3, associated with the lowering and retracting sides of the jacks respectively radial bores 15, 14 being provided. A compression spring 16 is arranged external to the plunger so that when the solenoid is de-energized, the plunger is in such a position that the passage 14 is obturated by the full bore of the plunger and the retracting line 3 is closed. When the pre-determined aircraft speed is reached and the electric circuit is completed by the expansion of the capsule, the solenoid is energized and the plunger is moved to the position shown against the spring 16, the retracting line 3 being opened. A selector valve 6 determines whether the jacks are to be operated for lowering or retraction. The waisted part 19 is of such a length that whatever the position of the plunger the passage 15 is never closed and the lowering line 2 is always open. To ensure non-interference with the lowering operation, whatever the position of the plunger a non-return valve is arranged in a byepass communicating with the pipe connections 12 so that the fluid can return down the pipe line 3 even if the plunger is in the closed position, Building up of pressure in the line 3 by prolonged holding of the valve 6 in the retracting position, when the plunger is in the closed position, is prevented by a further byepass having a non- return valve between the upper radial passages 14 and the passages 15. This byepass is interrupted when the plunger is in the open position. In a modification; the expansion of the capsule may break the electric circuit causing the solenoid to be de-energized, the valve being then put in the open position by using a tension spring instead of the compression spring 16.

Abstract: 791,075. Batteries. VOGT, H. March 19, 1954 [March 21, 1953; Jan. 23, 1954; Feb. 24, 1954; Feb. 24, 1954], No. 8190/54. Class 53. To limit the gas pressure in a sealed alkaline accumulator the cell containing the fully charged electrodes and separators is evacuated and then completely filled with electrolyte. It is then subjected to a further charge to expel a certain quantity of electrolyte and the cell is then sealed. Accumulators that may be treated in this way may have sintered electrodes having a thickness less than 1 mm. and separated by sheets of nylon, glass fabric, cellulose, &c., having a maximum thickness of 0.2 mm. Alternatively the electrodes may be separated by coatings applied to their surfaces, for example diatomaceous earth mixed with a solution of a synthetic resin. The electrodes may be flat or rolled on a core 20 as shown in Fig. 5. Due to the small distance between the electrodes the gases evolved from their surfaces combine with one another to reform water. To prevent bubbles leaving the exposed ends of the electrodes the latter are coated with a resin or other insulating layer 17 which is interrupted at 19 to provide communication between the spaces between adjacent electrodes and the space between the electrode pack and container. The layers 17 are joined to a plastic covering 21 which encloses the pack which is inserted in an outer metal casing 4. Specification 687,569 is referred to.
