Title: Improvements in illumination lenses
IPC: G02B9/12
Filed: 1963-08-13
Abstract: 1,029,427. Optical apparatus. GENERAL ELECTRIC CO. Aug 13,1963 [Sept 4, 1962], No. 31906/63. Heading G2J. A three-element lens assembly having all the lenses formed of material of the same refractive index for any frequency of radiation to which they are transparent, comprises two plano-convex lenses 14, 18. Fig. 2, having focal lengths P 1 , P 2  and spaced apart a distance d with the convex surface 28 of lens 14 facing the plane surface 34 of lens 18 and a double convex lens 16 between lenses 14,18 having a focal length P 3  wherein d < P 3  <SP><</SP> P 1  and d < P 3  <P 2 . As shown P 1  = P 2  and all the lenses are of fused quartz so that a wide frequency band is transmitted. The lens assembly may be used for producing an approximately collimated beam of radiation over a wide spectral range, of large area and of high uniformity over the cross section of the beam for simulating the effects of solar radiation upon a space vehicle, by arranging it as in Fig. 1, not shown, behind a mask 12 on which reflectors, associated with gas-discharge lamps 10, focus the radiation. The lens assembly focuses the radiation on to the surface of a paraboloidal reflector 20 which reflects substantially collimated radiation to the working surface 22. Radiation from lamps 10 which is not reflected by the individual reflectors passes through the lens assembly and forms a real image 24 which is the focal point of reflector 20 and is reflected by the latter to form a substantially collimated beam. Absorbing material, such as evaporated metal, may be applied to the plane surfaces 26, 34 of lenses 14,18, in varying density over the surfaces to correct deviations from the desired energy distribution. Chromatically correcting filters may also be applied to either or both surfaces.

Patent GB-967713-A (GB)
Title: Clutch mechanism
Inventor: DENKOWSKI WALTER JERZY
IPC: F16D21/02
Filed: 1963-08-16
Abstract: 967,713. Clutch control; valves; cams. PHILADELPHIA GEAR CORPORATION. Aug. 16, 1963, No. 32417/63. Headings F2K, F2L and F2V. A shaft 33, which carries a worm that drives a nut 30 to raise or lower a valve operating spindle 27, is automatically connected to a motor-driven shaft 47 or a hand-driven shaft 37, according to which is driving, by a double clutch sleeve 59 biased by a spring 108 towards a motor-driven gear 45 and moved left into engagement with a hand-driven gear 39 by a cam 61 which is fast with a gear 38 on the shaft 37 and acts through a pivoted shift fork 52 on the clutch sleeve 52. The spring 108 normally maintains the clutch sleeve 59 in the position shown in which it is clutched at 259 to the gear 45 to provide a motor drive to the shaft 33. In the event of motor failure the shaft 33 may be driven, by hand, from the shaft 37, initial rotation of which brings the cam roller 61 into engagement with a cam block 51 pivoted at 74 to a fork 72 on the shift fork 52 and urged by a torsion spring 76 to the position shown in Fig. 7. Further rotation of the shaft 37 and cam roller 61 tilts the block 52 against the action of the spring 76 and thereafter rotates the shift fork 52, clockwise, about its pivot 169. The other end of the shift fork 52 carries rollers 62 which engage a groove 359 in the clutch sleeve 59 which is thus moved axially left to disengage the clutch 259 and engage the clutch 159, 239. If the clutch dogs 159, 239 are not positioned for precise engagement the former 159 moves right relative to the clutch sleeve 59 and are pressed into final engagement by a spring 459. During hand operation the clutch sleeve 59 is retained in its left hand position by abutments 187, 188 on a pair of spring-urged levers 87, 88 which abutments engage a projection 80 on the shift fork 52. The above retaining means also hold the cam block 51 clear of the cam roller 61 during subsequent rotation of the shaft 37. The abutment 187 is <SP>1</SP>/ 32  of an inch lower than the abutment 188 so that when the motor drives the gear 45 a cam projection 92 thereon first moves the lever 87 outward and permits rotation of the shift fork 52 until the projection 80 engages abutment 188. On further rotation of the gear 45, the cam 92 moves the lever 88 outward to release the projection 80 and permits the spring 108 to move the clutch sleeve 52 right to re-engage the clutch 259 and to rotate the shift fork to the position shown in Fig. 3.

Title: Improvements in and relating to the pneumatic suspension of vehicles
Inventor: TREVASKIS HENRY WILLIAM
IPC: B60G17/052
Filed: 1956-10-27
Abstract: 869,346. Adjusting vehicle body height; dashpots. DUNLOP RUBBER CO. Ltd. Oct. 21, 1957 [Oct. 27, 1956], No. 32824/56. Classes 108(2) and 108(3). In a height regulating valve for a vehicle suspension an arm 2, Figs. 1, 2 connected to an unsprung part of the vehicle turns a hub 14 when the wheels are deflected by road bumps. A hub 14 puts a helical spring 23, Fig. 2, under torsion which is transmitted to a plunger 40, Fig. 1, by one or other of ends 24, 25 of spring 23. Plunger 40 cannot move quickly under the action of the spring 23 as it is restrained by pistons 47, 54 which with an oil reservoir 29, a passage 30 and a restricted passage 31 form a double-acting dashpot. Air-space 37a above a flexible diaphragm 37 acts as a displacement chamber when the dashpot operates. When additional weight is added to the vehicle the springs are compressed and the arm 2 turns the hub 14 anticlockwise in Fig. 1, causing end 24 of the spring 23 to urge the plunger 40 to the right. A piston 54, urged by flange 43 will displace oil through the closed circuit formed by the passage 31, reservoir 29, passage 30 and the piston chamber. Plunger 40 pulls on a pin 69 which rocks an actuator 122 about knife edges 121 to open a compressed air inlet valve 80 by pressing on a valve-stem 81. Air under pressure is thus admitted to the pneumatic springs through an inlet 95, a non-return valve 87, inlet valve 80, passages 84, 72, chamber 28, passages 106, chamber 102 and outlet connector 103. This air raises the vehicle body and moves the arm 2 and plunger 40 in the reverse direction. Plunger 40 moves back to its mid-position undamped since oil can flow through an annular hole 53 of piston 54 when flange 43 moves away from piston 54. Inlet valve 80 is thus quickly closed when the predetermined body height is restored. If the vehicle load is reduced the springs expand and the arm 2 moves the plunger 40 to the left, piston 47 now pumping oil round the closed circuit. Head 70 of pin 69 opens exhaust-valve 112 by pushing on plunger 118 which lifts the valve off its seat. Air from the springs escapes through connector 103, valve 112 and passage 107 to the atmosphere. The spring height is thus reduced and the plunger 40 is allowed to return undamped to its mid-position by the arm 2, valve 112 closing when the predetermined body height is again restored. The time delay of the dashpot may be altered, by adjusting a restrictor valve 33 in passage 31, to prevent corrections to body height being made whilst the vehicle is cornering. The invention may be applied to both pneumatic and hydropneumatic suspension systems, but in both cases it will operate on the pneumatic chamber only.
