Title: Improvements in or relating to roll film photographic cameras
IPC: G03B19/04
Filed: 1937-06-14
Abstract: 497,316. Photographic cameras. KODAK, Ltd. June 14, 1937, No. 19790/38. Convention date, Oct. 30, 1936. Divided out of 497,266. [Class 98 (i)] In a camera having a film-winding key turned by an arm moving between two limiting positions, the releasing trigger of a setting-type shutter is locked, except when the shutter is set and the arm is in its normal position of rest, in which condition the trigger is unlatched by a member connected with the arm and adapted to actuate the shutter setting member. The invention is described with reference to a camera in which the winding. arm must make one complete movement in one direction as described in Specification 497,266 and in which the arm is locked until release of the shutter as described in Specification 497,315. As shown the arm 31 operates the spool shaft 23 through a one-way clutch and is located in its position of rest by engagement of a handle 38 with a seating 35 in the casing. The arm is connected by a flexible connection 55 to a slide 57 held by a spring 94. The shutter is of the type described in Specification 497,392 and comprises a setting member 74 which when released rotates under the action of a spring 84 to rotate a pivoted driving member 72 actuating the shutter mechanism through an arm 71 engaging a post 66. On moving the arm 31 to wind the film the slide 57 is drawn along by the connection 55 and a lug 76 thereon engages a post 75 on the member 74 which is thereby rotated until a lug 77 thereon is engaged by latch 78 pivoted to the trigger member 79. The trigger is connected by a member 90 to an arm 87 pivoted to the casing and having a lug 89 extending downwardly into a groove 85 in the member 72 so that unless the lug 89 is raised from the groove the trigger cannot be operated by its release 82. On returning the arm 31 to its normal position after winding the film, the slide 57 is drawn by the spring 94 until a cam surface 92 on the slide raises the arm 87 to release the lug 89 and permit operation of the shutter. Specification 497,301 also is referred to.

Abstract: 841,052. Batteries. ACCUMULATORENFABRIEK VARTA N. V. June 26, 1956 [July 4, 1955], No. 19794/56. Class 53. An alkaline cell having a consumable-electrode is recharged by replacing the partially consumedelectrode by an auxiliary electrode of the same metal, charging the cell using the existing or fresh electrolyte and replacing the auxiliary electrode with a fresh-electrode after charging. The method is particularly applicable to Ni-Zn and Ag-Zn cells. If the existing electrolyte is used, the auxiliary electrode may be melted down after charging and the metal used for the production of further electrodes and if fresh electrolyte is used, the auxiliary electrode may be used several times and the old electrolyte regenerated by electrolysis to remove the dissolved zinc. Fig. 1 shows a cell having an easily removable zinc electrode 6 and a cylindrical sintered nickel electrode 3 mounted in a plastic container 1. The nickel electrode 3 is electrically connected to an iron base plate 2 and to a terminal 4 and the zinc electrode is insulated from the base plate by a plastic spacer 5. Before charging the cell is inverted, the zinc electrode is unscrewed and removed and a cup member carrying the auxiliary electrode is attached to the container end-cover 7. Fig. 2 shows a battery of similar cells in which the cell-containers 1<SP>1</SP> are united by flanges 12 to form a common casing. Conductors 14 series-connecting the cells pass through channels 15 in the flanges. The flanges 15 may be omitted and the separate containers held together by common cell covers 17 and 16. During charging the auxiliary electrodes are held in recesses formed in a single cup member. A cell having a square-sectioned container with a flat sintered nickel or silver electrode adjacent each wall and a central zinc electrode is referred to in the Specification as is cell having a pencil-type zinc electrode between flat sintered nickel or silver electrodes.

Title: Printing apparatus
IPC: B41J9/12
Filed: 1975-05-12
Abstract: 1495599 Printers DATAPRODUCTS CORP 12 May 1975 [15 May 1974] 19911/75 Heading G4H [Also in Division G3] An impact printer has a hammer bank 12 movable along the print line 50, i.e. to reduce the number of print hammers. A character drum 26 rotates and a character is printed when a hammer 23 hits the back of paper 18 whose front face presses print ribbon 29 against the desired character on the drum. The bank is moved along line 50 by a voice coil motor 64 (Fig. 8, not shown) and its velocity sensed by a magnetic velocity transducer, e.g. a tachometer (Fig. 2, not shown) giving a D.C. output whose amplitude and polarity give bank speed and direction. An optical positioner transducer controls bank motion and positioning using circuitry (Figs. 3 and 4, not shown). An error signal proportional to the difference between the applied velocity command signal and the tachometer signal is produced by a summing amplifier and is fed back to the summing amplifier which causes the hammer bank motor 64 to move at the commanded velocity. As the bank moves from one position to another, the position transducer output crosses the zero level three times and, when three crossings have been detected, deceleration is started. The bank is held at the desired position by the position servo loop and this position is known by the printer logic. The position transducer (Fig. 5, not shown) comprises a light emitting diode source, on a position encoder track with light and dark areas, co-operating with two photo-cells. After initialization the hammer bank is moved between two positions (right and left). The positions are spaced a distance equal to the character spacing so each hammer can be positioned in two print stations. In the bank, the hammer spacing is twice the character spacing so the number of hammers required is only half the number of printable characters per line. Alternatively, the hammer spacing can be made three times the character spacing.

Abstract: 1412699 Processing spent nuclear fuel AGIP NUCLEARE SpA 26 April 1973 [27 April 1972 (2)] 19991/73 Heading G6R Spent nuclear fuel is dissolved in a molten salt by dispersing the fuel in the salt and contacting the dispersion at an elevated temperature with a gaseous stream containing nitric acid vapour. The molten salt is preferably one or more alkali metal nitrates, for example eutectic mixtures of LiNO 3 , NaNO 3 , and KNO 3 . A halide, for example NaF, may be present in the melt as a catalyst. The gaseous stream may be formed by passing argon through a source of nitric acid vapours. The fuel may be an oxide, carbide, or nitride of U, Pu, or Th, or mixtures thereof; when the fuel is UO 2 , dissolution is accelerated by preliminary oxidation of the fuel to U 3 O 8 . Volatile fission products escape with excess nitric acid vapours, and noble and refractory metals do not dissolve and may be separated by filtration. On cooling the melt, for example to just above the melting point of the salt, purified fuel crystals separate out.
