Patent GB-1477426-A (GB)
Title: Printer
IPC: B41B19/00
Filed: 1975-10-10
Abstract: 1477426 Controlling printers INTERNATIONAL BUSINESS MACHINES CORP 10 Oct 1975 [11 Nov 1974] 41572/75 Heading G4H In printing characters of variable width, data bits representing a line of print are assembled in a buffer store and each group of bits associated with a particular character includes one or more pitch bits defining the width of that character independently of the widths of the other characters in the line. In the preferred arrangement, a laser beam 132, modulated at 136, scans an electrographic print drum 142 in 24 horizontal lines to form a line of print. Each horizontal "slice" of each character is represented by two words of 11 bits each for the right and left half respectively, each "half-slice" word comprising 9 modulation bits, own pitch bits and a parity bit. Register 144 receives the "half-slices" in succession from character generator modules 74 and passes all 9 modulation bits, or a selected 6 of them, to the serializer 146. Three different widths for each character may be provided; both halves 9 bits, both 6, or left half 9 and right 6. The letters I, F, M may be made 12, 15, 18 bits wide respectively. The printer may be controlled by a computer or flexible disk store 160 outputting 8-bit character code bytes in EBCDIC code which are assembled into lines of up to 204 characters in buffer 70, converted into graphic code in table 72, compressed at 76 (by dropping repetitions of like characters and encoding the number dropped), assembled into pages in buffer 78, and decompressed at 81. Minor modifications of pages may be introduced at 82. 64 character generator modules 74 are provided for each of 4  different fonts, and are addressed via line buffers 83, 84 which are used in overlapping alternation. The character generator modules 74 also receive signals from the computer and table 72, including pitch bits for each character, used for controlling the shape of the characters generated.

Title: Automatic bowling pin setting installation and a method of operating the same
IPC: A63D5/09
Filed: 1972-09-07
Abstract: 1400195 Bowling pin setter PATENTVERWERTUNGS-UND FINANZIERUNGSGESELLSCHAFT SERANIA AG 7 Sept 1972 [22 Sept 1971] 41584/72 Heading A6D A bowling pin setting installation conveys bowling pins, which are of identical shape and which are substantially horizontally disposed, consecutively along a common path alongside which are respective pin bins, and transfers a pin so conveyed into the first empty pin bin. As shown the conveyor system comprises conveyors 22, 33, 35, the conveyor 33 moving in the opposite direction to conveyors 22, 35 Transfer conveyors 25, 39 transfer pins from conveyor 22 to 33; and 33 to 35 respectively. Deflectors 36, 37, 38 ensure that the pins always point the same way irrespective of the direction of motion, i.e. head foremost on conveyors 22, 25 and 35 and base foremost on 33 and 39. A plurality of deflectors 11-13, 15-19 are arranged along the conveying path, each being associated with a respective pin bin. Each bin also has a respective drop flap 1-9. The presence of a pin in a bin depresses the associated drop flap to release the corresponding deflector so that the deflector is depresed by a subsequent pin. The deflector of an empty bin is locked in its operating position. Excess pins not allocated to bins fall off the end of conveyor 35 and are either returned to a sorting and pin feeding neechanism or the machine is stopped. "King" pins are sorted from ordinary pins and are delivered to a separate conveyor 44 which has a fixed deflector 14 associated with a single bin. An alternative arrangement for setting "ten pin" arrangements may utilise the invention. The pin conveyors are preferably comprised by parallel moving flexible cords. Bin mechanism In each bin the drop flap (9) (Fig 2, not shown) is pivoted about an axis parallel to the length of the pin and is spring loaded so that the edge of the flap bears down on a projection 58 (Fig 3) of a locking member 50 so as to engage notch 54 on a projection 60 of the deflector 19. A passing pin is therefore deflected into the bin, the drop flap then being pivoted about its axis by an amount sufficient to raise the edge nearest the conveyor and release member 50 to the position shown so that a subsequent pin may depress the deflector instead of being deflected. The drop flap is restrained from releasing the pin by a projection (72) which engages a member 66 (Fig 3) after the above mentioned pivoting. When the pin setter requires the binned pin the pin setter chair member 80 rises to cam the member 66 away from the flap projection (72) and the drop flap, being unsupported, continues to rotate about its axis to drop the pin into the chair. It then rotates back to the deflector locking position under the influence of the spring.

Abstract: 990,244. Hypodermic syringes. GRAHAM CHEMICAL CORPORATION. Nov. 23, 1961 [Nov. 23, 1960], No. 41993/61. Heading A5R. A hypodermic syringe comprises a barrel, a piston movable therein, an elastomeric member closing the discharge end of the barrel and formed with a passage extending therethrough, and a sealing member closing said passage but adapted to be expelled therefrom when pressure is applied to the piston. In Fig. 1 a cylindrical barrel 22 contains a piston 36 formed with two axial holes 37 into one of which is forced the inner end of a pistonrod 39. Projecting from the discharge end of barrel 22 is a reduced tubular member 24 formed at its end with a radial flange 23. A rubber member 26 has a disc portion abutting flange 23 and a cylindrical extension projecting into member 24. A passage 27 extending through member 26 is closed by a spherical sealing member 28. The needle 33 at its upper end projects into and is integral with a cup-shaped member 32, and a cylindrical extrusion 29 of the latter is crimped about the disc portion of member 26 and flange 23 to secure member 26 rigidly thereto. When piston 36 is moved inwardly, ball 28 is forced out of passage 27 and is held in cup 32. The sealing member may alternatively be disc shaped. The needle is protected by a sheath 35. In a modification the barrel and needle are made as a disposable unit usable in a syringe body 42, Fig. 3, formed with oppositely disposed slots 43. A piston 41 has a screwed stem which screws into the inner end of a piston-rod 49 passing through a plug 44 which screws into the outer end of the body 42 sufficiently to expel sealing member 28.

IPC: G03C7/14
Abstract: 429,211. Colour photography. RENWICK, F. F., 6, Reed Pond Walk, Gidea Park, and HARRISON, G. B., 23, Roden Street, Ilford, both in Essex. Feb. 19, 1934, No. 5482. [Class 98 (ii)] In a method of copying photographic images taken through lenticular or multicolour screens, the image of a light source formed through some or all of the elements of a portion of the master screen is photographically printed on to a portion of the copy and the positions of the screen forming device and the copy are adjusted to secure registration during the formation of the screen on the copy in accordance with the relative position, as observed by the eye or by a light sensitive cell, of the image on the copy and a fixed index. As shown applied to the lenticular screen process, the finished positive film is passed through an embossing machine comprising a flat surface 4 co-operating with a circumferentially grooved roller 5. The negative has a clear track along one or both longitudinal edges and during printing an illuminated slit parallel to the lenticular elements is arranged at a short distance from the negative films so that the lenticular elements produce fine black lines 8 on the positive. During embossing the lines 8 travel below slits 9 at a small angle to the length of the copy film in the plate 10. Light from a lamp 11 passes through the slits 9 on to a mirror 12 which reflects the light on to a screen 13. The embossing roller 5 may be slewed about the bearing 14 by the screw 15 engaging with the support for the bearing 16. The image on the screen 13 consists of bright lines 17 crossed by black lines 39. When these lines cross at a predetermined point the film and roller are in correct relative position. In a modification only one slit is provided, and an image of this slit is directed by means of a lens and mirror on to the junction of a pair of prisms which reflect the light on to a pair of photoelectric cells which operate an indicating galvanometer or an automatic device for controlling the position of the roller. In a further modification the plate 10 is omitted and the index is provided by a plate which forms the division between a pair of photoelectric cells. As applied to the multicolour screen process the embossing roller is replaced by an ink- or resist-applying roller, and the image on the copy is obtained by printing with light of the colour corresponding to the longitudinal lines.
