Title: Improvements relating to adjustable optical systems
Inventor: FULLAM ERNEST FRANCIS
IPC: H01J37/22
Filed: 1953-03-02
Abstract: 726,339. Optical apparatus. GENERAL ELECTRIC CO. March 2, 1953, No. 5785/53. Class 97 (1). [Also in Group XL (a)] An optical system for examining a beam of radiation or particles within a hollow enclosed structure, particularly for calibrating an electron microscope, comprises a fluorescent screen within the structure viewed by an objective and an eyepiece, means for varying the position of the screen relative to a support attached to the structure to select the area of the beam to be examined, and means for automatically maintaining constant the optical path length between the eyepiece and the objective as the position of the latter is varied. As shown in Fig. 2, the device comprises a tube 12 sealed into the side of the structure casing 16, and sliding within it a tube 20 carrying an objective 22 and supports 23 for a prism 24 the upper surface 25 of which is coated with fluorescent material and is covered with aluminium 26 to ground the static charge. Light from the screen after reflection at the prism and passage through the objective 22 passes a glass plate 17 providing a gas-tight seal and is reflected by a prism 27 into an eyepiece in a tube 21 sliding within a tube 13. Sliding movement of the tube 20 to cause the screen 25 to traverse the radiation beam is effected by a threaded rod 30a, Fig. 3, engaging a projection 32 on the tube 20 and rotated by a knob 28 through a shaft 30 connected to a portion 30b of the shaft 30a by a block 31. The portion 30b passes through silicone material 34 to form a vacuum-tight seal. To effect compensating movement of the tube 21 the shaft 30 drives a gear 37 meshing with a gear 36 on a vertical shaft 35 threaded at its upper end to engage and move a projection fixed to the tube 21. The device may also be applied to X-ray or electron diffraction apparatus.

In the construction shown the cylinder 7 is operated by compressed air and is pivoted at 6 to a cross-bar 5 having pivot pins 4 (not shown) adapted to fit in one or other of two inclined slots 3 on the wagon, so that the cylinder can be sloped in opposite directions for forward and reverse travel. The valve-box 12 of the cylinder contains a slidevalve 15 operated by an arm 24 on the piston rod 9 engaging abutments 22, 23 on the valve rod 21. The valve chamber 13 is connected by ports 16, 17 to another chamber 14 containing an automatic valve 18 adapted in one end position, as shown, to open the inlet port 19 to the cylinder and to close the exhaust port 20, while in the other end position it connects the inlet and exhaust ports and closes the connection to the port 16 which supplies compressed air to the valve box 12. The valve 18 is moved by the admission of compressed air to either port 17 or 17a. The cylinder may be operated hydraulically instead of pneumatically.

Title: Oxygen supply system
Inventor: SNOWMAN JOHN WASHINGTON
IPC: B64D13/04
Filed: 1960-02-24
Abstract: 895,373. Respiratory appliances. BRITISH OXYGEN CO. Ltd. Feb. 22, 1961 [Feb. 24, 1960], No. 6550/60. Class 81 (2). [Also in Group II] In breathing equipment for use at high altitudes air and oxygen are supplied under pressure and passed to a mixing chamber under control of metering valves, so actuated by pressure-sensitive means that the ratio of oxygen to air increases with decreasing ambient pressure and vice versa. Air is admitted under pressure, e.g. 70 p.s.i., to a chamber 24 while oxygen at, e.g., 150 to 300 p.s.i., is admitted to chamber 26. The two chambers are separated by a pressure sensitive diaphragm 25, which is connected through lever 27 to a valve 28 so that the rate of supply of oxygen to the system is directly dependent on the air supply pressure. The air and oxygen pass to a mixing chamber 15 through ducts 14, 21, respectively, the paths, in each case, being controlled by metering valves 17, 23, which are linked together by a rod 28 and actuated by a pressure-sensitive bellows 33 through a bell-crank 34. This bellows is evacuated and the chamber 29 is connected to atmosphere through a duct 30. Thus increasing altitude allows the bellows to expand and the rod 28 moves to the left, thereby tending to close the air valve and open the oxygen valve until, at a predetermined altitude, 100% oxygen is supplied. At low altitudes the bellows is compressed and the oxygen valve is progressively closed while the air valve is opened. The mixture passes through a valved aperture 36 to a supply trunk 37, whence it may be withdrawn for pressurizing suits or, through a demand regulator, for breathing.
