Title: Improvements in or relating to photographic cameras
IPC: G03B17/02
Filed: 1956-01-30
Abstract: 803,869. Photographic cameras. DECKEL, H., and DECKEL, F. W. Jan. 30, 1956 [Feb. 1, 1955], No. 2931/56. Class 98(1) In a photographic camera having an objective with a front lens carried by a screwed focusing mount which carries a distance scale co-operating with a mark on a fixed front plate, the front plate is spaced from the front of the shutter to house therebetween a depth-of-focus indicating device with pointers which indicate the depth of focus on the distance scale. As shown in Fig. 2, a shutter housing 52 is secured by a threaded ring 54 to the wall 58 of the camera. It contains a conventional shutter mechanism with a shutter speed setting ring 68, and the usual iris diaphragm adjusted by a setting ring 66. The shutter speed setting ring is connected to an external setting ring 72, and a coupling ring 74 which is engaged by a lug 76 on the diaphragm setting ring 66 carries a catch 78 which engages one of a series of notches 80 on the edge of setting ring 72. The ring 66 is springy so that the coupling ring 74 can be disengaged from setting ring 72, rotated with respect to the ring, and sprung back so that catch 78 engages a different notch 80. The objective lens is mounted in a bush 82 screwed into the shutter housing, and the front cell 88 of the lens is carried by a mount 90 which is screwed in and out of the bush 82 for focusing. The focusing distance scale 14 is mounted on the periphery 92 of the mount 90 (see also Fig. 4), and is read against a fixed mark 106 on a front plate 100. In the space between the plate 100 and the shutter housing 52 is mounted a depth-of-focus indicating device, e.g. of the kind described in Specification 785,857, and having pointers 10, 12 which indicate on the scale 14 the limits of the field of sharp focus. A scale 110 of shutter speeds is marked on the skirt of the setting ring 72, and a scale 34 of diaphragm apertures is marked on the coupling ring 74. The setting ring 72 and coupling ring 74 may be set in any relative position corresponding to a series of equivalent combinations of exposure time and diaphragm aperture, and any combination may be chosen by rotating the rings together to bring the required combination opposite mark 106. To facilitate relative setting or ring 72, 74, a scale 112 of total exposures may be provided on ring 74 to be read against a mark 114 on ring 72. Specifications 770,819 and 771,512 also are referred to.

Title: Method and apparatus for processing whole fruit
IPC: A23N1/00
Filed: 1954-02-01
Abstract: 753,988. Fruit juices. FOOD MACHINERY & CHEMICAL CORPORATION. Feb. 1, 1954 [Feb. 24, 1953], No. 2944/54. Class 14(2). Apparatus for de-juicing whole fruit comprises individual fruit-holding members 38, means for making an incision in the rind of a fruit whilst in the member, means for making an opening in the rind opposite the incision, pressure means 40 movable relative to the member and means for making the movement to apply pressure progressively to the rind at a zone outside the incision, the.opening, and a narrow space 202 adjacent the incision, whereby juice passes through the opening whilst the de-juiced fruit passes through the space. In operation, fruit is fed, in timed relation, to each member 38 as the means 40 begins to descend. Both members and means 40 comprise a series of equally-spaced circumferential fingers which, as the means 40 descends intermesh, thereby applying pressure to the fruit. An upper cutter 182 and a lower cutter 103 have respectively made the incision and opening, and when squeezing of the fruit begins the plug cut out to make the opening is forced into a finisher tube 66 followed by the juice which passes out through perforations 130 into a manifold 111. Meanwhile an outwardly sloping wall of the upper cutter 182 directs peel into the space 202 whence it passes through a chamber 155 after being slit by a knife 207 and shredded by the fingers of the means 40. Released peel oil and shredded peel particles are urged downwardly by the fingers, passing eventually to a trough. Full descent of the means 40 provides a seal (upper edge of a tube 65 extending into an annular recess in the cutter 182 and the lower edge of the cutter 182 extending into an annular recess 143 in the member 38) preventing peel oil entering the finisher tube 65. Plugs and residue pass through an opening for separate collection. The means 40 are moved by cam discs and rollers on a driven shaft. Orifice tubes 65, within the finisher tubes 66, are reciprocated by connections to cams on the driven shaft.

Title: Improvements in or relating to magnetic data storage devices
IPC: G11B5/40
Filed: 1957-01-28
Abstract: 793,237. Electric digital-data-storage apparatus. BRITISH TABULATING MACHINE CO., Ltd. Jan. 28, 1957 [Feb. 8, 1956; Feb. 17, 1956; March 16, 1956; May 25, 1956], No. 2953/57. Class 106 (1). A data-store comprises a magnetic drum 15, Fig. 2B, a magnetic reading or recording head 27 biased against the drum surface to form a wedge-shaped space between the head and the surface of the drum, a film of oil being applied to the drum surface which creates hydrodynamic forces in the wedge-shaped space acting against the biasing force to maintain the head in constant spaced relation to the drum surface. The drum is mounted on a vertical axis within a housing, which has openings to allow the reading and recording heads access to the drum surface. An oil pipe 16 mounted over another opening in the housing has holes 17 to project oil in small jets or spray against the drum surface. A wiper blade 23 removes excess oil to form a uniform oil layer 22. The housing is enclosed in a transparent casing to prevent oil being lost. Each reading or recording head is carried on a mount consisting in one form of two blade springs 28, Fig. 7, attached at one end to a fixed bracket piece 36 and at the other to a block 53. An arm 54 extending from the block engages in a slot 58 in the head assembly 60 and a pin 41, Fig. 2B, on the arm mates with a pivot bearing 42 in the head assembly so that it can tilt about an axis parallel to the drum axis. Skewing is prevented by a guide wire 29 projecting from the head assembly to engage in a slot 47 in an extension 45 of bracket 36. Two pairs of polepieces 27 project from the head assembly, the pole pairs being separated by a gap 32 which as shown in Fig. 2B, is displaced from the line of the pivot pin 41. The gap contains a thin spacer of non-magnetic metal which, with the ends of the poles is ground off to a smooth surface 31 adapted to ride on the film of oil. The upper and lower pole faces exert balancing forces which act against the spring force exerted by pin 41 to stabilize the position of the head assembly and by a " pontoon " action ensure that the pole spacings shall be equal. The head assembly in another form has a single head and a fixed tilt angle. In the form of Fig. 11 the head assembly 141 is supported on a single twisted blade spring 139 by means of a pin 136 engaging in a conical jewel bearing 146. The assembly has two pairs of polepieces and is stabilized by rod 155 as before. The pole faces are aligned with the drum surface by swinging the blade spring about the clamping screw 132. The oil pressure is provided by a pump driven from a pump motor. In the oil circuit are provided high pressure and lowpressure bellows which govern control switches adapted to stop the drum and the pump when the oil pressure exceeds a certain maximum or falls below a minimum value. The low pressure cut-off switch is by-passed by a time-delay relay on starting to give the pump about a minute to raise the oil pressure to the necessary minimum value, before the drum motor is energized.
