Abstract: 725,616. Aircraft occupant ejection devices. GOODYEAR AIRCRAFT CORPORATION. June 1, 1953 [Sept. 26, 1952], No. 15181/53. Class 4. An aircraft occupant ejection device comprises a substantially rigid protective enclosure fixed to the structure of the device and including a rear wall, side walls, and a top wall substantially defining the position of the occupant's head, and a substantially rigid head protecting face shield pivotally secured to said structure and rotatable from a face clearing position above and rearwardly of the head of the occupant to a position covering the occupant's face by rotation -about a horizontal movable pivot. In the embodiment described, side walls 4, rear wall 5 and top wall 6, all padded internally, are supported by brackets on rails 1 sliding on rollers mounted on the fuselage for ejection of the pilot's seat and pilot. Pivoted in holes 8 (Fig. 5) in the side walls is a face shield 9 adapted to be rotated through a right angle from a retracted position shown in full lines to an extended position about pivot 8. The key 13 (Fig. 5) is then aligned with a groove 20 in the side walls, and a hook 17 in the face shield engages a rod 19 on the top wall 6 to act as a pivot, the shield swinging about this pivot to the position in dotted lines, abutting the pilot's chest. A soft rubber strip 21 is used to protect the pilot and as a seal against onrushing air. A cable 24 (Fig. 5) is secured to a pulley 12 fast with the head shield and extends over pulleys 25, 26 to a strong spring 28 anchored at its other end to the rail 1. The tension in the spring first rotates pulley 12 about pivot 8 to rotate the face shield to its first dotted line position, and then pulls pulley 12 along track 20 to the final position. The shield is normally held in the retracted position by stop 16 and a catch engaging hook 17 which may be released by a cable 31 operated simultaneously with the seat ejection mechanism.

IPC: H05B41/19
Filed: 1926-06-17
Abstract: 253,927. Brettmon, J. June 17, 1925. [Convention date]. Low-pressure metallic-vapour apparatus, - An automatic lighting device for a quartz lamp comprises an inductance 2 in series with the lamp, and an inductance 1 which produces a high starting potential for a condenser electrode 8 arranged outside the lamp and near an electrode, and is cut out automatically when the discharge has started. The inductances are mounted on an iron core 3, and the inductance 1 is controlled by a circuit-breaker 4 shunting a circuit comprising condensers 11 and the primary 5 of a transformer, the secondary 10 of which is connected with the condenser electrode 8 and with the cathode 12. At starting the armature of the circuit-breaker is attracted to the core, thereby causing an impulse to be sent through the transformer to the starting-electrode, and the armature continues to vibrate until the discharge has started, after which it remains attracted to the core. The electrode 8 may consist of a wire or sheet of tungsten or other metal wound around the lamp and insulated by quartz, or of a quartz tube containing mercury.

Title: Improvements in or relating to liquid pressure master cylinders
Inventor: ANSELL RONALD WILLIAM
IPC: B60T11/228
Filed: 1958-05-13
Abstract: 849,147. Hydraulic brakes. AUTOMOTIVE PRODUCTS CO. Ltd. April 6, 1959 [May 13, 1958], No. 15324/58. Class 103 (1). In a master cylinder of the kind in which a valve element is provided in association with the master cylinder piston to allow liquid to flow past the latter during its return stroke and maintain the system to which the master cylinder is connected full of liquid even though the master cylinder piston may return more rapidly than the pistons in the wheel brake cylinders or cylinder, the piston 10 is formed with passages 19, 21 connecting an opening in its front face to an annular space 16 surrounding the rear part of the piston and a valve element 25 is provided to close the passage, the valve element being carried by a member 24 which is free to slide to a limited extent on a tubular extension 22 projecting from the front face of the piston head 11, and which has friction contact through V-shaped outwardly diverging limbs 29 of a sealing ring 28 within the cylinder walls 14 so that the member 24 tends to lag behind the piston 10 during movement of the latter. In operation, when the master cylinder piston 10 is applied the piston is advanced in the cylinder and the V-shaped sealing ring 28 on the member 24 is subjected to a friction drag due to its engagement with the wall 14 of the cylinder which causes the valve element 25 to be pressed against the front face of the piston head 11 to close the axial passage 19 and prevent escape of liquid through passages 19 and 21 to the reservoir (not shown) pressure is therefore built up in the master cylinder and itself tends to keep the valve element 25 firmly against the face of the piston head 11. When the piston 10 is allowed to return, the frictional drag on the sealing ring 28 of the member 24 tends to cause the latter to move away from the face of the piston head 11 and open the axial passage 19, so that at soon as the pressure in the cylinder drops sufficiently, the passages 19 and 21 in the pistons are opened, and free flow of liquid between the cylinder and the reservoir can take place through port 17.

Attached to the rod 1 by a boss 18 is an arm 22 having a pin 23 moving in a slot 25 in a rod 26 which operates the indicator mechanism. When the member 3 is under compression test, say, the rod 26 is first adjusted to zero by moving it to the left as shown in Fig. 4 so that the pin 23 is against the righthand end of the slot 25; upon stress being applied the inner ends of the rods 1, 2 then move towards each other, and the strain in the member 3 is thus transmitted to the indicator. The apparatus mav be permanently secured to the member 3 and amplifying means may be inserted between the rod 1 and the indicator. The means for fixing and supporting the outer and inner ends respectively of the rods 1, 2 may be varied and the apparatus may be used to indicate only the maximum strain reading. The apparatus may be calibrated to show stress, and may have several scales for indicating stress in different materials.

Title: Improvements in or relating to storage rooms, such as silos or cellars, particularly for vegetables, fruit or cheese
IPC: F24F5/00
Filed: 1945-06-19
Abstract: 630,550. Storage systems; ventilating buildings. KALBERMATTEN, C. DE. June 19, 1945, No. 15640. [Classes 20(i) and 137] [Also in Groups VI and XIII] In a process of treatment of perishable goods air passes over or through living vegetable matter acting as a humidity stabilizing material and over the goods being stored and the temperature and' humidity of the air in the storage chamber are maintained substantially constant. A food storage room or cellar is connected by air-ducts 2 to humidifier trenches 3 filled with living vegetable matter 4 e.g. moss. The roof structure, shown extending partly into the ground, comprises a sheathing 12, hygroscopic plates 11 supported by wire-mesh 10, and a bin 14 containing living vegetable matter. The roof sheathing 12 is lined with living vegetable matter 13, through which pass uptakes 8 from the ducts 2. Flues 15 connect the room to the outside by way of the vents 18. The flaps 7 act in the manner of a three-way valve to direct the incoming air from the trenches 3 either horizontally into the room or vertically into the uptakes 8. The flaps 5 and 6 control the top and bottom openings of the trenches 3, and the flaps 16 and 17 control the bottom and top openings of the flues 15, the walls of which are of wire mesh. The boxes 20 containing the goods in storage rest on sleepers 19, between which are porous-tile evaporators 21 which may also contain living vegetable matter such as moss. In cool weather the flaps 5 and 6 are arranged so that air is admitted through the trenches 3 and the ducts 2 into the room, and the flaps 16 and 17 may be open to assist air circulation induced by the warmer air rising from the goods being cooled. When the atmospheric temperature rises and the humidity of the outside air decreases the flaps are arranged so that the incoming air descends through the trenches 3, absorbs heat from its surroundings and rises through the ducts 2 and the uptakes 8 into the top of the roof jacket 13. A considerable evaporating and humidifying action is induced in the bin 14, and since in such case all openings of the storage chamber 1 are closed this action keeps its temperature low. The hygroscopic plates 11 induce some adjustment of temperature and humidity. A double door in an end wall gives access to the storage room by means of a ladder. If desired, the humidity stabilizing material 3, 14 and 21 may be connected to a water supply. Liquid cooling sprays and mechanical refrigeration may be operated in conjunction with the storage room.
