Filed: 1937-04-27
Abstract: 494,591. Kinematograph apparatus. KODAK, Ltd. April 27, 1937, No. 12053. Convention date, May 16, 1936. [Class 97 (i)] In apparatus receiving a reversible magazine having two exposure apertures normally covered by a resiliently-controlled shutter, two spring members are provided, one of which acts during insertion of the magazine, on a projection connected to the shutter to open the aperture in exposure position, and the other of which acts similarly when the magazine is inserted in reversed position. As shown, the magazine 10 has exposure apertures 11, 12, simultaneously covered and uncovered by a shutter 20 mounted on a pin 19, which projects from a gate plate 18 through the front wall of the magazine, and locates the magazine in the apparatus, as described in Specification 494,590. An operating member 22 is pivoted to the shutter, and has a pin 23 extending through a lot 48 in the front wall of the magazine ; a disc 27 on the pin 23 covers the slot 48, and a wire spring 44 engages under a bent part of the member 22 so as normally to turn the shutter into a position covering the apertures. Spring members 28, each comprising a substantially circularly curved portion 31 and a straight portion 32, are carried by studs 29, 30 in the apparatus. The magazine is inserted laterally in the manner indicated in Fig. 3, a spring- urged member 34, which normally holds the magazine in correct exposure position, being held, during the insertion, in the broken-line position shown, by a sliding latching bar 33 for the cover of the apparatus. Forward movement of the latching bar, after closure of the cover, permits the member 34 to move the magazine forward into exposure position, and the members 28 then lie close to the front of the magazine, one of them, during the operation, engaging the pin 23 and turning the shutter into open position. The other member 28 may then engage a locating pin 39 extending from the front of the magazine into an aperture 40 in the objective block of the apparatus. When the magazine is inserted in the reversed position, the actions of the members 28 are interchanged. Specification 494,589 also is referred to.

Title: Improvements in or relating to setting and drying aqueous coatings of hydrophilic colloids
IPC: G03C1/74
Filed: 1949-05-09
Abstract: <PICT:0690330/III/1> A process for setting and drying an aqueous coating of a hydrophilic colloid on a support comprises gelling the colloid layer by cooling it and drying the gelled layer by means of a current of air at a temperature which would normally cause the coating to flow but at such a rate that it is dried sufficiently before its viscosity is reduced to the extent necessary for the layer to flow.  In examples, the ranges of temperatures and drying times are given for coatings of gelatino silver halide emulsions upon cellulose acetate film or paper bases.  After the colloid has first been gelled the support may be passed through an additional zone at a low temperature to obtain a firmer gel, and the coating may be further improved by passing the support after the first drying through a secondary drying and conditioning zones.  A film 1 is taken from a reel over guide rolls 2 and 3 in a temperature-controlled chamber 4, the lower rolls 3 being mounted in a frame movable upwardly and downwardly, and is led from a coating unit 6 into a chilling tower 11.  Cold air is admitted to the chilling tower 11 from a chamber 10 and is withdrawn through a chamber 12.  The film is then taken through chambers 15 and 16 where warm air is impinged upon it from slots communicating with air ducts 17, 171 and 18, 181 in the chambers 15 and 16 respectively.  From the chamber 16 the film passes through two further drying zones 21, 211, the former, 21, being supplied with warm air through slots from a duct 25.  Finally the film is passed through a conditioning chamber 26 in which the temperature and humidity are controlled, and to a reeling device 30. Several of the lower rollers 29 in the conditioning chamber 26 may be given freedom of vertical movement.  Glass plates may be coated on a moving belt with gelatino silver halide emulsion in the above manner.

Abstract: 579,729. Predictors for gun fire control. STANDARD TELEPHONES & CABLES, Ltd., and BANNOCK, D. Sept. 26, 1941, No. 12501. [Class 92 (ii)] Relates to predictors for use in sighting anti-aircraft guns in which the rates of elevation and training generated in following the target are multiplied by the time of flight of the pro - jectile to obtain the lead correction for setting the gun. According to the invention, a single motor drives the sights through variable-speed mechanisms each comprising two pairs of bevel wheels connected by a floating friction ring, the distances between the bevel wheels of the pairs being. adjustable to suit the rates of change of the elevation and training angles in following the target. In the form shown, the training sight 2, Fig. 1, and the elevation sight 3 are mounted on a turntable 1 and viewed by operators who rotate handles 5, 19 respectively. The drive to the training pinion 10 is through a differential gear 8 and to the elevating arc 30 through a differential gear 22 and shafts 23, 26. The drives through the differential gears can also take place from a single constant-speed motor 66, Fig. 2, through frictional variable-speed gears 183 of the expanding pulley, rigid-ring type described in Specification 443,053, [Group XXIV], the motor 66 driving the sun wheels 88a, 87 of differential gears 88, one directly, and one through the variable speed device, the planetary-pinions 88c of the gears driving training shaft 17 and elevating shaft 40 in the appropriate directions. These shafts emerge, to drive the differential gears 8, 22, from a box 65, Fig. 1, which houses the motor and variable-speed units shown in Fig. 2. When the power drive is used, clutches 16, 31 are operated and the rates of training and elevating are then passed'to rotary camoids 93, 109 which are translated by a common drive from a " time of flight " wheel 41, the products thereby obtained being added to the present bearing and angle of sight by differential gears 43, 51 respectively which pass the future values of the deflections to the gun through transmitters 48, 62. The rate-drives also act through cams 107, 116 on the pulley extensions 83, 92 of the variable-speed device. Tangent elevation is added to the elevation drive by a cam 119 which operates through a cord 118 on an arm 117 screwed to control the protrusion of the pulley extension 92.
