Filed: 1953-07-23
Abstract: 794,492. Lamp-holders. LEVANE, R. Oct. 25, 1954 [July 23, 1953], No. 20504/53. Class 38 (1). A lamp lock comprises a split-spring ring 1 having axially projecting locking strips 7 and punched out loops 9. When the ring is positioned round the cap of a lamp and the lamp is inserted in a bayonet holder, the strips 7 block the axial parts of the bayonet slots and prevent removal of the lamp. Fig. 3 shows a tool for releasing the ring 1, comprising a U-shaped piece of spring-steel rod with the ends crossed and bent parallel to each other to form prongs 10a. Thus, when the prongs are inserted in the loops 9 and the part 10 is squeezed, the prongs diverge and expand the ring 1 thereby removing the strips 7 from the bayonet slots and permitting removal of the lamp. The ring can be rotated when expanded so that strips 7 engage the external surface of the holder until it is desired to remove the lamp.

Title: Improvements in and relating to photographic cameras
IPC: G03B9/64
Filed: 1939-11-22
Abstract: 536,523. Controlling exposure in photographic cameras. BULLMAN, S. W., and CARTWRIGHT, F. E. Nov. 22, 1939, No. 21031. [Class 98 (i)] A photographic camera is provided with means for simultaneously adjusting the shutter speed control through a constant ratio drive and the diaphragm control through a variable ratio drive, the means including a member oscillatable substantially about the lens axis which through a cam device imparts the variable ratio drive to the diaphragm such that the shutter speed and diaphragm settings give a constant exposure, means being also provided for adjusting either the diaphragm or the shutter speed independently. As shown, an annular plate 13 rotatably mounted on the ring 15 carries by means of an integral finger 17 an arcuate rack 18 engaging the toothed periphery of a concentric loss on a friction disc 20, which is gripped between the shutter speed setting knob 12 and the usual shutter adjusting cam 21. Rotation of the plate 13 by the lug 13a thus operates the knob 12 and cam 21 to adjust the shutter speed. Simultaneous adjustment of the lens diaphragm is effected by a curved arm 22 pivoted at 23 to the plate 13 and having a forked end 22a engaging over the stop-setting arm 11. A pin 22b on the arm engages in a cam slot 24 in a fixed plate, so that the arm, in rotating with the plate 13, is also given a pivotal movement relative to it about the pivot 23 ; thus providing a drive of varying ratio between the plate 13 and the stop-adjusting arm 11 which, by suitable shaping of the cam slot, gives the desired correspondence between the diaphragm and the shutter speed settings. The shutter speed may be independently adjusted by the knob 12, or the diaphragm adjusted by holding the knob and rotating the plate 13, the friction disc 20 slipping. In another form, the diaphragm is adjusted by a rotary plate having cam slots in which engage projections on the diaphragm blades, the plate also adjusting a speed-setting arm which is adjustably coupled to it by a resilient portion selectively engaging teeth formed on one edge of a slot in the rotary plate.

Filed: 1971-04-19
Abstract: 1336232 Gas discharge display panels TOKYO SHIBAURA ELECTRIC CO Ltd 19 April 1971 [5 Feb 1970] 21159/71 Heading H1D A gas discharge display apparatus which includes a cathode and an anode comprises a screen member of insulating material disposed between anode and cathode and having a plurality of plasma-pinching holes such that discharge light is produced from the pinched plasma in the holes. The envelope has a front panel 2 of glass, and may be filled with He, Ne, A, H or N optionally with Hg at a pressure of 4 mm Hg. The front panel 2 has a transparent anode coating 4 and the cathode 7, which may be cold or heated directly or indirectly, is approximately coextensive with the anode. The plasma pinching member 11 of glass or ceramic comprises a matrix of holes 12 whose walls have conducting coatings 13 which are connected to a scanning circuit. Application of a positive potential to anode 4 causes an anodecathode discharge the path of which is determined by impressing a positive voltage on a prescribed coating 13 by means of the scanning circuit. The plasma region 17 adjacent to the cathode becomes pinched in the area 18 within the plasma-pinching hole and the rapid variation of the electric field leads to production of light near the hole. In an alternative embodiment (Fig. 6) a transparent glass sheet 23 is in contact with the opaque perforated member 22 and a plurality of conductive transparent anodes 24 are disposed in the holes 21. In a further arrangement including transparent sheet 23 and perforated member 22, the walls of the perforations form conductive anodes to produce plasma pinch light and the base of each pinch hole is coated with a thin fluorescent layer 26 (Figs. 8, 9, not shown). In another arrangement (Fig. 10, not shown) a fluorescent layer is formed on the inner face of the front panel 2 together with a plurality of anode plates which are in register with the 2-D matrix of holes in the perforated member, the conducting layers in the plasma pinch holes and the anode plates being supplied with positive voltage by a scanning system. In one scanning system (Fig. 24) the columns of conducting layers 13 are conductively connected apart from the layers in the first column which form reset cells. A reset signal is applied to V 1 and positive voltage pulses are sequentially applied to H1, H2 and H3. H1 is connected to display columns 1, 4, 7 &c., H2 to columns 2, 5, 8 &c. and H3 to columns 3, 6, 9 &c. such that sequential pulsing to H1, H2 and H3 causes the discharge to scan the complete row. After scanning one row a reset signal to V2 initiates the second row scan. In a modification (Fig. 23, not shown) the reset conductor layers are interconnected to reduce the addressing circuitry. Typically 200 V. is applied to the anode from source 53 and 100-150 V. to the conductor Layers from scanning source 54.
