Title: Improvements in or relating to the Production of Printed Reading Matter and the like Photographically.
Inventor: BUNNELL ISAAC SAMUEL
IPC: B41B17/02
Filed: 1917-06-01
Abstract: 117,282. Bunnell, I. S. June 1, 1917. Index type - case machines for photographic copying. - Relates to methods of producing letterpress reading-matter photographically, to be used subsequently for reproduction by any well-known process, and consists in first tracing from a negative alphabet &c. a rough outline copy of the words, symbols, &c. desired, and then printing from the negative the selected fancy characters accordingly. A carriage 13, Figs. 1 and 3, is mounted to slide laterally upon a frame 12 and bears a felt pad 19 over which sensitized film 20 is fed by means of feed-rollers 23, 24, 25, 26 operated through bevel-and-spur gearing from a spacing-handle and indicator 32. The negative 50 bearing the alphabet of fancy small and capital letters is secured to a plate 51 having lugs 52, 53 taking against a ledge 54 so as to limit the forward and rearward sliding movements of the plate, indexes and scales 65 - - 68 for the letters enabling the operator to set the negative as desired. The negative is photographically produced from an original drawn by the artist. A pointer 70 upon a gauge 71 fixed to the frame 12 co-operates with the scales on the negative, the gauge extending over a " copy " slip 72 adjustably attached to the carriage 13, which is made in the first instance by the operator, who traces the required characters from the negative. Within a lamp casing 92 mounted upon an arm on the frame 12 over the negative is an electric lamp 93 or other source of light; when the arm is depressed by means of a knob 107, contact 102, 104 is made in the lamp circuit and the rays are directed by a lens 94 upon the negative through an apertured stop 96 which presses thereon and prevents movement. This operation occurs for each letter or character printed, the negative being moved laterally and backwards and forwards to select the characters, and the carriage fed laterally to space the printed letters, the paper-feed effecting line-spacing. A selective stop-system for use with alphabets the letters of which vary in height is also described.

Abstract: 859,083. Paper-making machines &c. SAINT ANNE'S BOARD MILL CO. Ltd. June 7. 1957 [June 12, 1956; April 16, 1957], Nos. 7910/57 and 12382/57. Divided out of 859,082, Class 96. Pulp from a flow-box K flows to the wirecloth A of a Fourdrinier paper-making or boardmaking machine at a position where an upper wire-cloth B passing about an imperforate roll C forms, with the wire-cloth A, a tapering gap E wherein the pulp is compressed and the lower wire A is forced downwardly to the position G (shown as a broken line). Water expressed through the upper wire B travels up a waterway J and into a trough T due to its momentum as it moves with the wire B. The lower edge of the waterway J bears against the wire B, to limit the extent of the tapering gap E. The pulp is further compressed between pairs of rolls 18, 19, and 20 and suction nozzles 24, 25 withdraw more expressed water. After leaving the wirecloth B, the web may be couched off and passed to conventional press and dryer sections, or it may remain on the wire A and more pulp may be deposited thereon from a second flow-box, such pulp being similarly formed and felted into the first web to make multiple-ply paper-board &c. Instead of, or in addition to, the waterway J there may be a suction-box for upward withdrawal of water. The front of such a box may be sloped &c. to act as does the water-way J. In another modification, side-plates are fitted at the tapering gap E. Specifications 748,597 and 780,587 are referred to.

Abstract: 1392451 Photo-taking booths C W CLARK 29 March 1972 [29 March 1971] 8022/71 Heading G2X A self-processing film unit comprising a superimposed film sheet 39, Fig.14 and image receiving sheet 41 both connected to a leader 44, is fed to a guide 161 and then a guide 162 is pivoted downwards from the Fig.11 to the Fig.14 position, so that the flexible leader 44 and film 39 pass around the guides but the inflexible receiver 41 does not and is thereby separated from the film. As described the invention is incorporated in a coin operated photographic kiosk in which a sitter is photographed by a camera 5 for single pictures or a camera 6 for multiple pictures (see Fig.7) via mirrors 11,12; Fig.1 (not shown). As shown in Fig.7, cassettes each containing eight film units are stored in holders 54,55 and are fed to and ejected from a cassette support plate 105 by a horizontally reciprocated plate 47; plate 105 being reciprocated vertically in synch with plate 47 to move the cassettes to and from the exposure plane in cameras 5,6. After a film unit has been exposed it is withdrawn from the cassette by clamps 121, 128, Fig. 11 carried by horizontally moving carriages 122, 129. The unit is drawn through rollers 104, Fig 8 (not shown) which rupture a developer pod in the unit, and then the film and receiver are separated by the guides 161,162. The film is ejected by a belt 175, and the receiver is carried by rollers 183, 184 and a belt 172 to a receptacle 196 for the customer. A photo-transistor (not shown) operates an alarm if the machine goes wrong. Specifications 1392041 and 1392042 claim other parts of the machine.

Abstract: 1,040,931. Combined electric and combustion heated continuous furnaces. WEST MIDLANDS GAS BOARD, and GARRINGTONS Ltd. March 4, 1963 [March 3, 1962], No. 8317/62. Heading F4B. A metal heating furnace comprises a continuous path for the passage of metal billets progressively through an initial phase of the furnace in which the metal is heated by burners and a final phase which includes induction coil heating. Billets (not shown) enter a tunnel 7 from a guide 8 and are slid along rails 9 by a pusher (not shown) through a gas-fired furnace 4. Downwardly directed burners 13 and laterally directed burners 14 heat a forcing section 11, the resulting gases heating a preheat section 10 before escaping through a flue outlet 15 in which an eductor 16 is provided. Laterally directed small burners 17 heat a soaking section 12 in which the billets acquire a uniform predetermined temperature. Manual or automatic control means are provided for the burners. A flue outlet 18 with eductor 19 withdraws products emanating mainly from the forcing section and prevents them passing to a short induction coil 5. From the exit end of tunnel 7 the billets pass to the induction coil 5, where their temperature is raised to the ultimate value required, and are then discharged by shoot 20. The rails 9 through the induction coil and the induction coil itself are water cooled.

Abstract: 558,062. Vehicle lamp masks. DENNIS, E. D. June 19, 1942, Nos. 8399 and 9318. [Class 75 (iv)] A mask for vehicle head lamps &c. shown in Figs. 3 and 5 comprises a closing plate 1 of metal or other opaque material fitted to the front of the lamp in place of the usual glass-carrying bezel and having mounted in a rectangular aperture formed by bending outwardly a downwardly inclined canopy 4 and inwardly side wings 3 a number of metal louvre members 5 having depending flanges. The side flanges 8 abut against and are secured to the side wings 3 and the rear flanges deepen at their ends 6 so that the beam emerging at the sides has the correct downward inclination. The lower edges of the front flange 11 and side flanges 8 of each member 5 are level with the highest point 12 of the next member below it. The upper surfaces of each member is formed with inclined portions 9, 10, Fig. 2, the portion 9 being in line with the lower edge of the flange 11 of the member next above and the portion 10 being only slightly receptive of light. The ends 13 of the surfaces 10 shallow gradually opposite the ends 6 of the rear flanges. The members may have rounded corners and be provided with drainage holes. The wings 3 may support a translucent or transparent plate 14 at the rear of the units 5 and reflecting mirrors 33, 34 are provided between the members 5 to amplify the light rays issuing laterally of the lamp. The canopy is extended to cover the members 5 by welded flanged plates. The plate 1 may have a translucent panel to act as a regulation side light. Instead of the louvre members extending through the plate 1 they may be arranged wholly on one side of the plate. The side wings 3 may be dispensed with and the members 5 supported by angle pieces welded to the closing plate 1. Fig. 12 shows another construction of mask in which grids 21 arranged between louvre units 22 comprise members 24, 26 transverse and parallel to the lamp axis having their upper edges aligned with the edges of the flanges on the louvre units to prevent the emergence of light in undesired directions. The members 26 may be extended to form suspension members 27 for carrying the grids.
