Title: Photographic film assemblage
IPC: G03B17/34
Filed: 1971-07-02
Abstract: 1361831 Film assemblies EASTMAN KODAK CO 2 July 1971 [2 July 1970 (3)] 31115/71 Heading G2X  A film assembly comprises a plurality of selfprocessing film units each having a leader, the units being connected together so as to be, in use, drawn seriatim from a camera, the assembly presenting only a single leader for manual grasping, and the connections being such that, on drawing a leader to withdraw a film unit, a next leader is presented exteriorly of the assembly and is stripped from the preceding leader. Fig. 1 shows the type of film unit forming part of the invention, and comprises a photo-sensitive element 12 having an exposure portion 16 and a print-receiving sheet 14 having a framed portion 30. A first leader sheet 24 is attached at one end 51 to the leading end 22 of the photo-sensitive element. From end 51 the leader extends between the photo-sensitive and print-receiving sheets towards the trailing skirt 20 of sheet 16, then round the leading end of sheet 14 to the side thereof opposite sheet 16, ending at 52 where it is attached to the cover sheet 40. This latter is an opaque sheet which surrounds all the units of the assembly to protect against premature exposure prior to its being inserted into the camera, the assembly preferably being housed in a suitable cartridge 42. The second leader sheet 26 is attached at one end to the first leader sheet 24 half way between the leading and trailing ends of the sheets 14 and 16, and at the other end to the print-receiving sheet. The cover sheet 40 has no separate leaders, but has an integral leading end 56. When the assembly is placed in a camera, part of whose wall portion is indicated at 68, the leader 56 extends between the pressure-applying members 66, 67 which clamp together on opposite sides of the leader when the camera back is closed. When leader 56 is pulled, the photo-sensitive element is presented in the exposure position, the cover sheet is withdrawn between members 66, 67, and the leading end 52 of the leader sheet of the first film unit pulled out, after which the cover sheet is stripped from it. The end 52 is now exterior of the camera Fig. 4, (not shown), and may now be grasped for pulling the first film unit out of the camera. In successive stages in this step Figs. 5-7, (not shown) sheets 14 and 16 are brought into correct register, and then, as they are pulled between members 66, 67 the container 32 of processing fluid is ruptured. At some time prior to this, the leading end of the first leader sheet of the next film unit is threaded between members 66, 67, and stripped from the exposed unit Fig. 6, (not shown). Superpositioning, processing, and withdrawal of the sheets is effected by a "lost-motion" type of connector that first permits and then prevents relative movements between the sheets as a respective leader is withdrawn from the camera. Figs. (not shown) 8-33 are of some alternative arrangements of the film sheets.

Title: Improvements in or connected with radio-navigational apparatus and the like
IPC: G01S1/02
Filed: 1919-12-15
Abstract: 160,250. Murray, J. Erskine-, Robinson, J., and Crowther, H. L. Dec. 15, 1919. Directive signalling; bearings, determining thermionic modulating systems and apparatus.- In a wireless direction-finding system, a directional transmitting station is adapted to emit successively along compass bearings between North and South a continuous wave of short wave-length, which is constant for all directions of transmission and has its amplitude modulated at a supersonic frequency which varies as a function of the direction of transmission. The receiving-station, Fig. 2, comprises a circuit 13 tuned to the high-frequency wave-length, and a second circuit 17 tunable to the frequency of the supersonic modulations, which are interrupted into groups of audible frequency by an interrupter 18 or combined with oscillations from an independent source 22 to form audible beats. If the circuit 17 is tuned to the modulation frequency at the moment of minimum radiation in the .direction of the receiving station as the transmitted wave rotates in azimuth, two equal swells of sound will be heard in the receiver, depending upon the tuning of the circuit 17 with regard to the modulation frequency transmitted, and the varying amount of energy received due to the orientation of the transmitting system. If the circuit 17 is not tuned to the modulation frequency at the moment of minimum radiation, two unequal swells of sound will be heard. With an interrupter 18, the pitch of the note is constant, but when using a heterodyne circuit 22 the pitch varies as well as the intensity. The circuit 17 is calibrated to the modulation frequency so that the direction of the transmitting station can be read off when equal swells of sound are heard. The transmitted wave has its amplitude varied by varying the high tension voltage applied to the power valve of a transmitter 4, Fig. 1, by controlling the potential across a choke 5 inserted in the positive lead from a direct current source 7, by means of a control valve 8, having its anodefilament path across the choke. Modulation is effected by coupling the grid circuit 9 to the anode circuit 5 or to an independent oscillating circuit, the wave-length of which is controlled by a condenser 10, or inductance, which is varied with the rotation of the aerial 11, Specification 149,826 is referred to.

Abstract: 787,702. Repeater housings; cables. FELTON & GUILLEAUME CARLSWERK AKT.-GES. Nov. 7, 1955 [March 26, 1955], No. 31724/55. Classes 36 and 38 (1). In a submarine cable installation incorporating repeaters, the cable consists of a central, strain taking steel rope 1 having a copper sheath 2 serving as an inner conductor and surrounded by insulation 3 in the form of layers of polystyrol strands wound alternately in opposite directions. A corrugated tube 4 forming an outer conductor surrounds the insulation 3, the corrugations being filled with liquid insulation, e.g. polyisobutylene. Finally a jute covering 6 is applied. Fig. 3 shows the cable connected to one end of a repeater housing consisting of a sheet-metal cylinder 8 and end cones 7 surrounded by interfitting rubber hose parts 9, 10. The repeater components are supported on plates 23 carried by strain-taking members 14 in turn carrying a cone 19 which grips the splayed out end of the insulation 3 between itself and a central cone 18. The ends of the insulating strands are secured in a disc 16 supported by a plate 22, and the steel rope 1, which passes through cone 18, is cast in a lead cone 15. Outer conductor 4 is welded to the cone 7. Another way of anchoring the cable is shown in Fig. 4. A plate 25 carried by the members 14 has a recess in its underside for the lead cone 15 and supports on its upper surface a cylinder 24 in which the ends of the insulating strands 3 are cast with synthetic material. Bolts secure cylinder 24 and a support 26 for cone 15 to the plate 25. In order to assist the corrugated tube 4 in the pressurisation of the interior of the repeater, expandible vessels 27 are fitted in the walls of the repeater housing and communicate with the exterior thereof. An alternative method of gripping the insulating strands 3 is by means of a series of concentric insulating cones, Fig. 5 (not shown). Instead of the members 14 a central strain-taking rope 33, Fig. 6, may be employed. The cable end is anchored to a plate 38 similarly as in Fig. 4, said plate being bolted to a further plate 39 with the interposition of an insulating plate 41. Plate 39 supports a lead cone 37 in which the end of rope 33 is cast, the latter passing through the centre of pressure-resisting housings 34 for the repeater components, which housings are separated from each other and from a casing 46 around the cable anchorage, by rubber bushes 47.
