Title: Photographic camera with an automatic exposure regulating device
IPC: G03B7/12
Filed: 1962-12-03
Abstract: 1, 009, 710. Photographic cameras. AGFA A.G. Dec. 3, 1962 [Dec. 6, 1961], No. 45647/62. Addition to 918,457. Heading G2A. The camera of the parent Specification in which application to the camera of interchangeable lenses of different maximum apertures effects adjustment of the location of the needle of a photoelectric exposure meter relative to a clamping jaw of an exploratory exposure regulating device in accordance with the maximum aperture of the applied lens, is modified in that the adjustment means is also operatively connected to a device for causing change of the image field bounding marks visible in the camera viewfinder. As shown, attachment of the normal lens does not affect the pin 206 and lever 205 and the field bounding marks 319 normally visible through the slots 321, 322 in the slidable masking plates 310, 311 remain unobscured. If a lens of the same field but a smaller maximum aperture is applied to the camera, an abutment on the lens will engage and move the pin 206 as the bayonet connection is effected so that the lever 205 moves a slide 302 which rotates the meter 208 bodily through a rack and pinion drive and similarly rotates a cam 309. Since the cam surfaces 309a, 309b which are effective are concentric with the cam axis the masking plates are still not moved. On attaching a wide angle lens of smaller aperture, the meter 208 will be rotated through a larger angle and the cam surfaces 309c, 309d will displace the plates 310, 311 to cover field bounding marks 319 and uncover marks 320. With a telephoto lens the cam 309 is rotated even further so that the plates 310, 311 are separated to uncover field marks 318 while covering marks 319, 320. In an alternative embodiment, (Fig. 2 not shown), the field bounding marks are masked by a rotatable plate moved by a slide controlled by the objective abutment sensing lever and the photo-electric exposure regulating device adjustment is effected by a cam on the objective abutment sensing lever displacing the exploratory clamping jaw 213 along its pivot axis and so adjusting the relative positions of the cam surface 212 and the meter needle.

Abstract: 1,067,059. Fluid-pressure brakes. ROCKWELL - STANDARD CORPORATION. Oct. 29, 1965 [June 22, 1965], No. 45836/65. Headings F2E and F2F. [Also in Division E2] In an actuator assembly for a vehicle brake, two spaced fluid pressure responsive diaphragms 38, 39 are mounted within a housing 17 to form separate fluid pressure chambers, one of the chambers (42) being connected to a service fluid pressure line via connection 16 and the other chamber (43) is adapted to be connected to an independent auxiliary fluid pressure line via a connection at 28, a brake actuator wedge member 52 being operatively connected to the service pressure diaphragm 38 such that when the diaphragm members 38, 39 are independently displaceable in the same direction for moving the actuating member 52 in the brake-applying direction, a wedge and roller locking means 83, 63, 98 is adapted to lock the actuator member against return movement until a piston means 69 under the control of the vehicle operator is actuated to selectively release the locking means. Fig. 3 shows the condition wherein the service air pressure system has failed and the operator will note this by failure of the brakes to respond to his pedal operation or by a suitable visual signal and he selectively applies the independent auxiliary air braking system by a manually operable valve to supply air under pressure to the branch conduit 28 into the auxiliary air pressure chamber 43 of each brake actuator. This pressurizes the chamber 43 and moves the diaphragm 39 to the left as shown in Fig. 3 to apply the brakes through the wedge actuator 52. The wedge 77 associated with the diaphragm 39 is also moved to the left and the air pressure in chamber 43 together with the force of the spring 73 moves the piston 69 to the right to move the cage 83 housing the rollers 81 and 82 of the wedge and roller device also to the right to wedge against the surfaces 98 on release of the auxiliary air pressure from the chamber 43, the wedge actuator 52 is kept in its applied position since the wedge and roller mechanism 77, 83 prevent return movement of the diaphragm assembly 39, 38 until the operator actuates a valve to introduce fluid pressure through conduit 33 to pressurize the chamber 76 and move the piston 69 to the left to release the wedge and roller mechanism 77, 83 and allow the parts of the brake actuator to return to their inoperative positions. Provision is made in a modification (Fig. 8, not shown) to allow for manual operation of the piston 69 to release the brakes by means of a plunger inserted in the end wall 72 of the brake actuator.

Abstract: 1,108,235. Measuring surface roughness and symmetry of bores. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Nov. 2, 1965 [Nov.10, 1964], No. 46381/65. Heading G1M, [Also in Division G2] An optical instrument for determining the internal dimensions of a tube comprises two optical systems arranged so that, when inserted in the tube, light passing through the first system is directed into the interior surface of the tube and thence through the second system, the two systems being mounted in tube inserts 12, 13 which are coupled together, the second system including an annular slit diaphragm 21 and being movable relative to the first along the axis of the tube so as to bring the diaphragm 21 into alignment with the light passing from the tube surface, the movement being effected by a micrometer which indicates the variations in the interior surface of the tube. As shown the first system comprises two annular lenses 15, 16 separated by an annular slit diaphragm 17 and housed in an annular passageway 18 of the upper tube insert 12. The second system comprises two annular lenses 19, 20 separated by the annular slit diaphragm 21 housed in the insert 13, the two inserts being coupled together by a pin 25. Light from a source 14 housed in the insert 12 is directed by the first lens system on to the interior of the tube under inspection. Light reflected therefrom passes through the second lens system and is reflected by a frusto-conical mirror 26 which directs the annular beam of light along the tube towards a photographic film, for example. Variations in the interior surface of the tube will require movement of the diaphragm 21 in the direction of the tube length until the slit of the diaphragm registers with the annular beam of light incident thereon. This movement is effected by rotation of a screwthreaded spindle 30 which engages a screw-threaded bore 45 in the insert 13 and abuts against a cylinder 28 which slides in the insert 13 and mounts the diaphragm 21. The spindle 30 is rotated by a micro-motor 29 on operation of a micrometer screw 32. In a second embodiment, the annular optical systems are replaced by linear projection systems, the inserts 12, 13 being arranged to rotate together so that a beam of light passing through the first lens system scans the interior surface of the tube.
