Title: Improvements in and connected with photographic cameras
IPC: G03B17/50
Filed: 1923-03-24
Abstract: 215,910. Frank, C. March 24, 1923. Magazine cameras with simple quarter-turn change and fitted with darkrooms and means for preparing and treating negatives; focusing arrangements.-A camera for ferrotype plates comprises in combination (1) a magazine sildably fitting into the camera body and rotatable through 90‹ to present the plates to the changing-mechanism with either their longer or their shorter edges horizontal, and (2) a rotatable leaf operated by an external handle, and carrying a magnet which lifts the plates in turn from the magazine into the focal plane. The camera also comprises (3) a focusing-screen adapted to spring into the focal plane when the magnet is swung towards the magazine (4) a slide operated by the changing- mechanism for rendering the magazine light-tight during exposure (5) means for detaching a plate from the magnet after exposure, and (6) a multicompartment developing &c. tank in a casing detachably secured to the camera body. In the form shown the camera A, having a lens B and shutter B<1> is fitted with a frame E which receives a magazine C containing plates D, and is adapted to be rotated about a vertical axis through 90‹ by an external handle F<2>. The plates are raised by a spring-urged plate C<1> to present the uppermost plate to a magnet K, carried on a leaf I mounted on a shaft L, when the leaf is swung down by operating an external handle on the shaft L. An aperture F<3> permits the insertion of a finger to free the plates should they become jammed. A sliding cover N is controlled by linkage O, P from the shaft L so that it automatically covers the magazine C when the leaf I is swung upwards to bring the plate lifted by the magnet into the focal plane. As the leaf I swings down to pick up a plate, a focusing frame U mounted on arms V, V<1>, falls into the focal plane; the frame U is pushed back into inoperative position when the leaf I is raised. A member Q, slidable against spring action on rods T, T<1>, is drawn downwards by a cord R after exposure to disengage the plate from the magnet. The plate then drops through a slot in the camera base into one of three intercommunicating developing-tanks G, G<1>, G<2>, which, together with washing and drying tanks G<3>, G<4>, are contained in a casing. H removably secured to the camera. The camera is fitted with a door at one side, giving access to the changing-mechanism and with a coloured window at the rear. The permanent magnet K may be replaced by an electromagnet with a switching arrangement, controlled partly by the leaf I during its movements, to cause the electromagnet to pick up a plate, and partly by hand to release the plate after exposure. Instead of being rigidly connected to the leaf I, the magnet K may be swung on links pivoting on the leaf, so that it dips into the magazine C to extract a plate; with this construction the push plate C<1> is unnecessary.

Title: Improvements in or relating to amplifying systems comprising thermionic devices
IPC: H03G3/06
Filed: 1920-03-24
Abstract: 141,033. Western Electric Co., (Assignees of Arnold, H. de F.). March 28, 1919, [Convention date]. Thermionic relays.-In a thermionic amplifying system for amplifying electric impulses, the circuits are so arranged that the ratio of amplification may be varied without varying the impedance presented by the amplifier as a whole to the impulses to be amplified. The impulses to be repeated are impressed upon the grid circuit of the tube 10 and the amplified impulses in the anode circuit of the tube 10 are impressed on the resistance 25 by currents induced in the secondary coil 24. The input electrodes of the second tube 11 are in shunt with an adjustable part of the resistance 25, and any desired proportion of the potential drop across the resistance may therefore be impressed upon the grid circuit of the second valve, with the result that the ratio of amplification may be varied between a predetermined maximum and zero. Since the battery 27 maintains the grid 13 at a negative potential with respect to the filament 12, no current can flow therebetween, and since the capacity of these electrodes is negligibly small, the impedance of the tube to incoming impulses is substantially infinite, and hence substantially constant, for all positions of the adjustable contact 26. A common source of current 20 supplies the anode current of both valves, filters consisting of series inductances 21, 28 and shunt capacities 23, 32 being interposed to prevent alternating currents in one anode circuit from passing to the other. The first amplifying unit with its output transformer may be replaced by any suitable circuit adapted to have electric currents produced therein.

Patent GB-762216-A (GB)
Title: Improvements in manufacture of resins
IPC: C07D301/28
Filed: 1954-03-26
Abstract: A process for producing epoxy resins comprises heating epichlorhydrin or glycerol dichlorhydrin with a dihydric phenol free from reactive groups other than phenolic hydroxy groups in the presence of sufficient aqueous caustic alkali to combine with the chlorine of the chlorhydrin and with the addition of not more than about 20 per cent of the resin formed of an organic solvent which is insoluble in water but which is a solvent for the chlorhydrin and for the resin at high temperatures, producing a resin-solvent mixture which can be washed with water to remove salt and any excess alkali at a lower temperature and thinner consistency than is possible without the solvent, washing the mixture with water and heating the product to dry it.  In a modification, the solvent may be added to the formed resin instead of before or during the reaction.  Resins having melting-points below 100 DEG  C. and high melting-points, e.g. up to 150 DEG  C. or higher, may be produced in a single step process without the use of pressure.  The reactants may be in equimolecular proportions or either may be in excess of the other.  Suitable solvents are high-flash naphtha, xylene, toluene, mineral spirits, cyclohexanone and di-n-butyl ether.  The solvent may be distilled off or may be left as part of the solvent for subsequent use, e.g. in coating compositions.  The preferred dihydric phenol is p,p1-dihydroxydiphenyldimethyl methane; others specified are resorcinol, hydroquinone, catechol, phloroglucinol, p,p1 - dihydroxy - benzophenone, -diphenyl and -dibenzyl, bis-(4-hydroxyphenyl) sulphone, 2,21 - dihydroxy 1,11 - dinaphthyl methane, and dihydroxy naphthalenes and anthracenes. A number of examples is given. Solutions of the resins may be mixed with ureaformaldehyde resins and applied to tin panels from which bottle caps are made.

Abstract: 1,012,257. Fuel elements; reactor control rods. EUROPEAN ATOMIC ENERGY COM. MUNITY (EURATOM). March 4, 1964 [March 8, 1963], No. 9095/64. Heading G6C. [Also in Division B3] Fillings in tubes or in containers of annular cross-section are compacted by a pilger deformation, the ends of said tubes or containers being closed. The filling is preferably a precompressed powder and the articles so produced may be nuclear fuel elements or control rods, the latter being filled with boron carbide powder. Annular section rods are internally supported by a mandrel. The basic pilger process comprises mounting the tube on a mandrel between two opposed rolls rotated by a limited amount in opposite directions, the rolls having eccentric peripheral grooves which are conically tapered and extend over approximately 180 degrees of the periphery. After each rolling operation, the rolls release the tube, which is rotated axially through about 60 degrees before the next rolling operation commences. When the complete circumference has been rolled, the workpiece is axially displaced to move that portion reduced to the required size from the working area, and the process is then repeated. The apparatus comprises a pair of pilger rolls 10, a drive 11 for rotating the fuel rod 14, mandrels 12a, 13a and chucks 12, 13. The fuel rod is traversed between the pilger rolls by a carriage 15 driven by a leadscrew 19. Fuel rod end plugs 14c are welded to the can. The mandrels 12a, 13a may be replaced by further fuel rods in a continuous process. Members such as wires, cables and struts may be placed in the container prior to rolling. Where the container is formed by the annular space between two concentric tubes, the inner tube is internally supported by a mandrel.
