Title: Improvements in or relating to a combined range finder and view finder or a range finder alone
IPC: G03B13/24
Filed: 1944-02-21
Abstract: 574,993. Range - finders and viewfinders. KODAK, Ltd. Feb. 21, 1944, No. 3209. Convention date, March 11, 1943. [Classes 97 (i)and 98 (i)] In a combined view-finder and rangefinder an adjustable objective 10 forms an image in a primary image plane P in which there are a field lens 16 and means such as wedges 15, 15<1> arranged with their bases on opposite sides of the optical axis for deviating rays falling on them in opposite directions so that three overlapping images will be formed in a plane conjugate to the objective 10 with reference to the field lens 16, in which plane a selector stop and erector lens 11 select a portion of the overlapping images which are viewed by the eye piece 14. The image as viewed at 21 is shown in Fig. 5 and comprises the field of view with, in the centre, a laterally split image of the object being ranged upon. When the objective is focussed to bring the image plane into the plane of the wedges and field lens, coincidence is obtained and the boundary of the range field disappears. The field lens and wedges may be moulded from transparent plastic material, Fig. 4 (not shown). The device may be applied to a camera, in which case the objectives of the camera and the rangefinder are the same, the film being supported in the primary image plane of the camera objective, and, by connecting the range-finder and camera objectives by a lever mechanism, the camera will be in correct focus when coincidence is obtained in the rangefinder, Fig. 8 (not shown). When the device is used as a rangefinder only the deviating means covers the whole area of the field lens.

Title: Image dissector tube
IPC: H01J31/42
Filed: 1941-03-10
Abstract: 547,259. Image dissectors. FARNSWORTH TELEVISION & RADIO CORPORATION. March 10, 1941, No. 3232. Convention date, March 11, 1940. [Class 39 (i)] A television picture signal generating tube comprises an evacuated envelope 1 including a photoelectric cathode 3 on which an optical image is focused by lens system 4, the optical axis of which is perpendicular to the cathode, means such as anode coating 6, focusing coil 13 and deflecting coils 17, 19 for producing an electron image in the plane of a transparent screen 20 situated in and perpendicular to the path of the light forming the optical image intercepting all but the minute area of the electron image, which passes through aperture 21, and means such as the electron multiplier 23 disposed within the envelope but outside the light path for collecting the electrons passing through the aperture. When employing long-focus lenses for direct transmission of kinematograph film, the usual solid tube containing the scanning aperture throws an undesirable shadow on the cathode ; by the present arrangement, no opaque bodies intercept the light-path. The screen 20 is supported in a ring 7 engaging anode coating 6 and supported by stays 8, 8A, one of which is a lead. The grid 23A covering the entrance to the multiplier is connected to the second multiplier electrode, so that it forms with the screen 22 (at cathode potential) an attractive field for electrons passing through aperture 21.

Filed: 1944-03-02
Abstract: 590,776. Artificial limbs. BENSON, B. S. March 2, 1944, Nos. 3951 and 13343. [Class 81 (ii)] An artificial arm or part thereof, including a hand portion having fingers formed in movable parts, is provided wherein the movable parts of all the fingers together or of each finger separately are actuated by movements of the forward part of the foot including the toes of the wearer. Individual fingers have their movable parts operable by movements of individual toes, and the hand portion is actuated by movement of the ankle. In the joints of the articulated fingers (Fig. 1) reside strips 4 and inflatable bulbs or bags 3 which are connected by flexible tubings 5 to hollow compressible pads 6 one of which is arranged under each toe 7, so that the depression of any toe forces fluid from the pad to expand the bulbs in the joints of a particular finger causing the sections thereof to turn about their pivotal joints. Where the upper limb includes an articulated wrist, the latter may be endowed with an up and down and/or turning movement effected by compression and release of suitably placed pads by movements of the ankle and/or heel. Mechanical or electrical means or combinations of these either separately or in combination with hydraulic (or pneumatic) means may be used; for example, in mechanical operation traction or Bowden wires, plates, pads and plungers may be employed and for electro-mechanical operation small electric relays or electro-magnets may be incorporated in the artificial limb. The actuating means may be rendered inoperative by fitting a valve, switch or its equivalent in the circuit. The return movements of all the movable parts can be effected by spring means.

Title: Process for the production of chlorurethanes
IPC: C07C271/06
Filed: 1953-02-13
Abstract: Hardenable resins are produced by the condensation of aldehydes with the dichlor-diurethane of the formula <FORM:0722676/IV (a)/1> prepared by reacting pentaerythritol with cyanogen chloride (see Group IV (b)).ALSO:In a process for the production of a chlorurethane of the general formula Cl.R.O.CO.NH2 wherein R is an aliphatic residue which may contain further terminal Cl and O.CO.NH2 radicals in equal numbers, cyanogen chloride is heated with a polyhydric aliphatic alcohol.  The reaction in general may be carried out in a melt of the polyhydric alcohol, e.g. cyanogen chloride may be passed into fused butanediol but for complete reaction suitable diluents, e.g. organic solvents such as glacial acetic acid or benzene, are either allowed to flow in during the reaction to keep the chlorurethane formed in solution or are added beforehand.  From 1.4 - butanediol, 1 - chlorbutylcarbamate - 4, butanedioldichlorurethane and dichlorbutane are produced.  The formation of tetrahydrofurane is favoured by increase in temperature.  The reaction may be carried out under increased pressure and high yields of chlorurethanes are produced when the diol is pumped into cyanogen chloride, diluted if desired, in an acid resistant pressure vessel.  In examples, 1-chlorbutyl-4-urethane is obtained when cyanogen chloride is passed into fused 1.4-butylene glycol until the mixture becomes pasty and the latter is extracted with water, dichlorbutane and butanediol diurethane being obtained as by-products (1); in similar processes glacial acetic acid (2) and benzene (3) are employed as solvents; a dichlordiurethane of the formula <FORM:0722676/IV (b)/1> is obtained by passing cyanogen chloride into a boiling mixture of pentaerythritol and glacial acetic acid (4); cyanogen in methylene chloride is heated in a silvered autoclave and butanediol-1.3 is pumped in to obtain the chlorurethane, diurethane and dichlorbutane (5) and in a similar process ethylene glycol is converted to chlorethyl-carbamate (6).
