Title: Camera-microscope
IPC: G02B21/36
Filed: 1956-05-02
Abstract: 802,753. Microscopes; photo-micrographic apparatus. ZEISS-STIFTUNG, C., [trading as ZEISS, C., [Firm of]]. May 2, 1956 [May 17, 1955; May 18, 1955], No. 13475/56. Classes 97(1) and 98(1) In a microscope having a beam-splitter to provide partial pencils for simultaneous visual observation and photography, alternative paths of observation are provided by a reflecting device such that the beamsplitter may be by-passed by a direct reflection to the eye-piece or included in the optical path by reflection from another surface of the device. The optical path in the second case includes a projection eyepiece, the beam-splitter, a graticule in an image plane equivalent to the plane of the photographic emulsion and a telescope objective. The components are preferably totally enclosed in a limb of the microscope which carries at its end objective 4 and eye-piece 3. After total reflection in prism 11, the light passes to projection eye-piece 13 and, the beam transmitted by semi-transparent plate 14 'forms an image on the photographic light sensitive material 16 in plate-holder 15. Lens 20 forms an image of the exit pupil of objective 4 at or, at least approximately, at the aperture of telescope objective 21. An additional beam-splitter 17 may be provided, the transmitted beam energizing a photoelectric cell 19 operating an exposure meter or automatically controlling the luminous intensity of the light source 6. The image formed in the plane of the graticule 18 is observed by means of telescope objective 21 and eye-piece 3. A compensating eye-piece 3 is used and lens 23 is provided to give rise to the same amount of lateral chromatic abberation as is residual in the rays emergent from the objective 4. These emergent rays may be reflected directly to the eye-piece 3 on sliding the composite prism of the reflecting device Fig. 2, longitudinally so that the ray a coincides with the optical axis of the objective 4. In this position of prism 11 the rays 'from the objective are transmitted through a cemented interface. In a second position, partial reflection takes place at the interface and the reflected ray b<SP>11</SP> may actuate the photo-electric cell 19. Total reflection takes place in a third position, as shown in Fig. 1. When prism 11 is moved into a fourth position the rays a from the objective pass through the bore 27 to auxiliary projection apparatus (not shown). The graticule 18 may comprise double lines resolvable by the eye-piece to facilitate focusing the camera.

IPC: D06F71/06
Filed: 1951-06-13
Abstract: 697,132. Ironing-presses. WHITAKER, Ltd. R. G. May 5, 1952. [June 13, 1951] No. 14016/51. Class 138 (ii). [Also in Group XXIX] In a garment press having a head which is brought down into pressing relation with a fixed lower buck by delivering compressed air through a main control valve 28 into a cylinder 29 whose piston is connected to the head, the air supply line 31 to the main control valve 28 is provided with an automatic cut-off valve 8, and the air supply line between the valve 28 and the head operating cylinder 29 is branched to a third valve 16 capable of a variable predetermined opening, a variable pressure device 30 being interposed between the valves 8 and 16 and being subject to air pressure through each so as to shut the cut-off valve 8 after a predetermined time depending on the degree of opening of the valve 16. The variable pressure device comprises a pair of differential pistons 4, 5 or diaphragms having a common spindle 7 and received in cylinders 2, 3 of different diameters. The spindle 7 also carries a conical valve disc constituting the cut-off valve 8. As shown, valve 16 is a needle valve and has a pointer 26 moving over a scale 27 which may be. marked in press head pressures or in time units indicating the delay between opening of valve 28 and closing of cut-off valve 8. Operation. On opening the main control valve 28 air is delivered past the cut-off valve 8 through pipe 31, valve 28 and pipe 32 to the head-operating cylinder 29. If valve 16 is closed the cut-off valve 8 remains fully open so that full pressure is applied to the press. If valve 16 is open, some air bleeds off from the outlet side of valve 28 through a pipe 33 to the larger piston 5 and causes the piston assembly 4, 5 to move towards cut-off position at a rate depending on the degree of opening of the valve 16. The air in cylinder 29 expands and its pressure drops until the press head engages the buck at the required pressure. The fully open position of valve 16 may be such that the cut-off occurs sufficiently quickly to prevent actual contact between the head and buck, thus permitting steaming of a garment without pressure.
