Title: Photographic transfer processes
IPC: G03D9/00
Filed: 1954-05-27
Abstract: 752,403. Photographic transfer process. CHEMISCHE FABRIEK L. VAN DER GRINTEN N.V. May 27, 1954 [June 3, 1953], No. 15757/54. Class 98 (2). To effect transfer a sheet of imagewise exposed light-sensitive material and a sheet of receiving support material at least one of which is moistened are brought together and guided between a lower element of hard porous material and an upper element of resilient material at least one of which has a cylindrically curved pressing surface. Such transfer may be that of unexposed silver halide from the light-sensitive material to form a positive image in the receiving material by procedure as of Specifications 614,155 or 654,630, or may be that of a stratum of emulsion containing silver halide or silver formed therefrom or of pigment or other material as described in Specifications 655,274, 655,275, 740,165 and 740,166. Nine forms of apparatus designed for manually carrying out the process are described, thus in Fig. 1 a porous stone plate 11 constituting the lower element is mounted on wheels 34 running on rails 35, and a rubber-lined roller 1 constituting the upper element is mounted in bearings carried by a support 22 in fixed position relative to the rails 35, to permit exposed and moistened material 41 on the plate 11 to meet receiving material 42 applied by hand 45 and be run along under roller 1 for transfer and thereafter separation by hands 46 and 47. The plate 11 may be reloaded and run in the reverse direction for the next transfer. Figs. 2-7 (not shown) are directed to the use of (2) a slanting table and a clamping roller adjacent to the roller 1 to facilitate application of the receiving material 42 to the pressing zone; (3) a stone plate 11 of part cylindrical shape and mounted for reciprocating movement beneath the roller 1 ; (4) provision for rolling the roller 1 over the stone plate 11 which is mounted in an inclined position; (5) a part cylindrical upper resilient element designed to rock over the lower porous element; (6) both elements of part cylindrical shape; and (7) both elements in the form of rotatably mounted cylinders. In Fig. 8 the receiving material 42 is in the form of a continuous web unrolled from roller 43 to be pressed against exposed material 41 between elements 1, 11 both in the form of rollers, and may proceed over roller 49 to be wound up on reel 44 while the exposed material is taken off by hand 47. Fig. 9 (not shown) illustrates a modification of Figs. 1, 2 and 4 in which the element 11 has a slot to receive the end of the material 41 to facilitate removal thereof from material 42 after transfer. Specification 672,844 also is referred to.

Title: Improvements in or relating to liquid dispensers
IPC: B67D7/08
Filed: 1961-05-02
Abstract: 965,694. Dispensing petrol &c. TOKHEIM CORPORATION. May 2, 1961 [May 2, 1960], No. 15940/61. Heading A4T. In a petrol or other liquid dispensing apparatus, including a device for printing a ticket recording the volume dispensed, a latching mechanism is provided to ensure that after an initial printing of the ticket the apparatus can perform only one dispensing operation and is prevented from performing a second until a further printing of the ticket has been effected to complete the record of the volume dispensed. The ticket to be printed is inserted in a shoot 11, Fig. 1, and a crank 7 is turned manually through one revolution to effect the initial printing, and also to move the shoot 11 from position A to position B. A collar 223 on a cable 199 secured to the shoot 11 then moves to allow a bell crank 211 to be turned counterclockwise by a spring 225 until an arm 215 thereof rests on a hook 235, Fig. 4, of a panel 227. The arm 215 is thus held out of latching engagement with a cam follower 95 so that a cam 51 may be rotated clockwise by the handle 82 to operate mechanism for resetting the dials 15, 17 for registering the volume dispensed. On further clockwise rotation of the handle 82 a cam 84 closes a switch 88 to energize the pump motor to initiate the dispensing operation. Additionally such further rotation actuates cam mechanism to project a shaft 29 into engagement with the end 233 of the pawl 227 to withdraw the hook 235 from the arm 215. The bell crank 211 is then rotated by the spring 225 so that on rotating the handle 82 counterclockwise to terminate dispensing a projection 219 on the cam follower 95 engages in a recess at the end of the arm 215. This prevents subsequent clockwise rotation of the handle 82 to initiate a second dispensing operation until the crank 7 has been turned another revolution to complete the printing of the ticket and to return the shoot 11 to the A position. The collar 223 on the cable 199 then engages and rotates the bell crank lever 211 to raise the arm 215 out of its latching position to be held by the hook 235. Specifications 776,014, 823,864 and U.S.A. Specification 2,086, 368 are referred to.
Patent GB-1375262-A (GB)
IPC: G11C27/00
Filed: 1972-04-06
Abstract: 1375262 Electroluminescence HUGHES AIRCRAFT CO 6 April 1972 [15 July 1971] 15960/72 Heading C4S [Also in Division H1] In a field sustained image storage and display device the photoconductive layer consists of a cadmium sulphide layer which has been heat treated at 385-525‹ C. for 1 to 60 minutes and is contacted by an electrode of which the surface abutting the sulphide consists of areas of one material surrounded by another material. The typical device shown in Fig. 1 is made as follows. After depositing antimony doped tin oxide on glass plate 14 to form transparent electrode 15 electroluminescent zinc sulphide containing copper, manganese and chlorine is vapour deposited and then heated for 5-15 minutes at 675‹ C. Germanium, alone or mixed with silicon monoxide is deposited to form opaque anti-feedback layer 17 and then the cadmium sulphide is vapour deposited from a tantalum boat to a thickness of 2-15 Á at a rate of 0À5-10 Á/hour with the substrate held at 100-200‹ C. and the walls of the deposition chamber at 40-90‹ C. After heat treatment, e.g. at 500‹ C. for 1 minute in a flow of argon, nitrogen or air it is preferably cooled to 70‹ C. over a period of 20 minutes. An electrode layer 21 2500 A thick and containing a few per cent of gold is provided by simultaneously depositing gold from an electron beam evaporator and silicon monoxide from a Drumheller source. Alternatively aluminium, silver, platinum, tin or germanium may be used instead of gold and magnesium oxide instead of silicon monoxide. A similar structure can be obtained by first precipitating a single layer of metal particles or depositing a discontinuous layer of metal and then applying a layer of the oxide. In operation with electrode 21 positively poled, projection of an image or scanning with a modulated laser beam produces a conducting image in layer 18 and a corresponding optical image in the electroluminescent layer. These images can be maintained for up to 30 seconds if the applied voltage is maintained but layer 18 reverts to the non- conducting state in 10 milliseconds on removal or reversal of the voltage. Another use of the device is in integrating low level light images. Reference has been directed by the Comptroller to Specification 1,338,337.

Title: Automatic voltage regulating systems
IPC: H02P9/20
Filed: 1947-06-17
Abstract: 642,411. Automatic voltage control systems. BENDIX AVIATION CORPORATION. June 17, 1947, No. 15996. Convention date, June 27, 1946. [Class 38 (iv)] A carbon pile voltage regulator for a variablespeed dynamo is associated with a second carbon pile shunting a portion of the dynamo field winding. Normal voltage control, is achieved by connecting in series with the field winding 2 a carbon pile 5 actuated by a voltage coil 9. A coil 29 is connected across the pile 5 so that as the voltage across the pile approaches a maximum, the coil opens contacts 13, 14 and closes contacts 23, 24 connecting across the lower portion of the tapped field winding a second carbon pile 16 and connecting the actuating coil 20 thereof in series with the field winding. Thus as the dynamo speed rises, carbon pile 5 maintains a constant voltage by reducing the field current until at a predetermined minimum, relay 29 switches in carbon pile 16 which maintains .that minimum field current by shunting a portion of the field winding, thus reducing the effective ampereturns of the field and enabling carbon pile 5 to continue to maintain a contact voltage output. Specification 625,825 is referred to.

Title: A printing device for use in connection with calculating machines, and particularly tabulating machines controlled by perforated cards
Filed: 1931-06-04
Abstract: 380,472. Statistical machines. KNUTSEN, K. A,, 239, Ljabrochausseen, Ljan, Norway. June 4, 1931, No. 16309. Convention date, June 4, 1930. [Class 106 (i).] In selective-printing mechanism for calculating-machines, particularly record-controlled tabulating-machines, comprising a series of rotatable supports each carrying a number of type-members, means co-operating directly or indirectly with the type-members causes the types to effect impression by rolling over the paper. The mechanism may be associated with a total-printing arrangement. In the apparatus shown in the Figure, a rotary disc 58, forming one of a series, carries pivoted type-members 42 having types 61 for printing on a web 56 running over a platen roller 55, or a flat platen backed by springs. Segments 41 on the typemembers are geared by pinions 40 to pinions 39 on stop-arms 34 pivoted on the disc and cooperating with a stop-lever 33 which is normally retained by a projection 97 on a lever 32 connected to the armature 45 of a magnet 44. When a perforation in a record card passes the contacts, the magnet is energized and the stop-lever is released, and is moved by a spring 96 into the path of one of the stoparms, the associated type-member being thereby caused to roll over the web and effect impression. The active stop-arm moves the stoplever out of the path of the subsequent stoparms, a latch 37 retaining the stop-lever. At the end of the cycle the latch is released by means of a rotary cam 38. Springs 35 hold the type-members and stop-arms in normal position. In an alternative arrangement, the typemembers have lugs for directly engaging the stop-lever, the stop-arms and gearing being dispensed with. The apparatus may include counting-wheels controlled by magnets in circuit with the magnets 44, and associated with means for printing totals. For this purpose, each counting-wheel is provided with a stepped cam 15 co-operating with a feeling- lever 16 which co-operates with a stepped cam 11 and carries contacts 75, 76 in circuit with the magnets 44. At total-taking the shaft 17 of the cam 11 is coupled to the shaft 60 of the discs 58, and a cam 25 permits springs 26 to advance the feeling-levers into positions determined by the cams 15. When the type-members corresponding to the active steps on the cams 15 are approaching the printing line, the cams 11 close the associated contacts, and the stoplevers 33 are thereupon released to initiate total-printing.
