Title: Automatic xerographic apparatus
IPC: G03G15/30
Filed: 1959-10-28
Abstract: 944,940. Xerographic projection copying apparatus. RANK-XEROX Ltd. Oct. 28,1959 [Nov. 28, 1958], No. 36516/59. Headings G2A and G2H. Apparatus for reproducing images recorded on transparencies comprises a feed station for said transparencies, means for causing each transparency to be brought in turn from the feed station to a projection station so as to lie between illuminating means and a lens for projecting the transparency on to a xerographic surface, and means for processing the xerographic surface and producing a permanent xerographic reproduction of the transparency. Preferably each transparency is moved at a constant rate between the illuminating means and a slit aperture projection system and the xerographic surface is moved at an appropriate rate so that there is no relative movement between it and the projected image. In order to accommodate transparencies of different lengths or to exclude symmetrically disposed leading and trailing portions of the transparency, the start and end of the path of movement of the transparency may be adjusted. As shown, for reproducing microfilm frames on record cards, the cards are placed in a hopper 7 and are extracted one at a time from the bottom of the stack by a picker 57 and fed by rolls 71, 72 on to a card carriage assembly 75 where it is clamped in a card carriage 101 by an optical flat in a pressure frame 115. The card carriage is then moved uniformly along guide rails at right angles to the direction of card feed so that a projected image of the transparency produced by lens 17, mirror 20 and mirror 21 or 22 is scanned by a variable stationary slit 23 and is recorded on a xerographic drum 24 which rotates continuously past successively charging, exposing, cascade developing, discharging, powder image electrostatic transfer, drum cleaning and second discharging stations. The slit 23 is arranged to be wider at its end that in the middle and the powder image transferred to the paper web 29 is fixed at 32 where heaters are disposed at an angle to the web direction. The machine is adapted to be set to provide magnification ratios of 15 or 20 times by selection of mirror 21 or 22 and adjustment of the card carriage scanning movement rate. Instead of producing a single copy of the transparency on the card, a series of copies may be made by causing repeat scans before the card is changed. Card change is effected when the carriage is in its start of scan position by ejector rods 145 which move the card into the nip of a roller pair including driven roller 84 whereby the card is transferred to a receiving hopper 8. The Specification describes with reference to an electrical circuit diagram (Fig. 13 not shown) the automatic operation of the machine including start-up and shutdown operation including operation necessitated by machine faults such as failure of card feed and servicing requirements, and testing procedures. Specification 938,501 is referred to.

Abstract: 814,901. Automatic exchange systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Dec. 18, 1956 [Dec. 22, 1955], No. 36822/55. Addition to 791,856. Class 40 (4). The parent Specification discloses a magnetic drum in which impulses are registered temporarily in a storage position which is the same for all the various trains of impulses on one line, the registration being subsequently transferred to a storage position characteristic of the train of impulses concerned. In the present invention the temporary storage position is located on an auxiliary track and the registration is subsequently transferred to the main track assigned to the signalling line concerned. As shown, a signalling line is associated with a block such as TZ2 on one of six main tracks T1-T6. The section TY14, used in the parent Specification for the temporary storage of impulses, is replaced by one of sections TY9-TY14 in the preceding block on the auxiliary track. Scanners PA1-PA6 are associated with the main tracks and test the state of the associated lines at time TX3, electronic relay MAN being set up when a line is looped to enter a mark in position TX4 of the appropriate section TY9-TY14 of the auxiliary track. MAN is reset automatically at time TX6. MAN also operates if the line is continuously open but if the line changes from looped to open MAN does not operate and a mark is entered over lead SBN in position TX5, or in TX6 if there is already a mark in TX5. Transfer to the appropriate main track takes place at the sixth subsequent rotation of the drum, i.e. when that main track is next being scanned. Lead SLM is energized to set up MBN alone or with MCN according to whether one or two impulses are to be transferred. These electronic relays control MAB and MBB which are as described in the parent Specification and add the impulse or impulses to the digital storage space in known manner. MDN and MBB are used to initiate release if the calling party hangs up.

Abstract: 828,667. Percussive tools. MODERNAIR CORPORATION. Nov. 14, 1956, No. 37334/57. Divided out of 826,645. Addition to 826,646. Class 124. The driving piston of a pneumatic driving unit as claimed in claim 1 of the parent Specification has an upwardly extending rod carrying a return piston of small diameter working in a cylinder in an upper closure, the underside of the return piston being connected alternately with the container and with the atmosphere. As shown, a container 215 for air under pressure is connected to a cylinder 244 having a working piston 228 carrying a rod 269 fitted with a return piston 268. A control piston 239 closes the cylin. der 244 with its underside and its upper side is in communication with the container through a channel 249. On closing a valve 253 to prevent pressure air acting on the top of the piston 239 and at the same time opening the space above the piston to atmosphere, the pressure air in the container acts on an annular area on the bottom side of the piston 239, raising it and allowing pressure air to force the 'piston 228 downwardly to a working stroke. As the piston 239 rises pressure air is admitted below the piston 268 through channels 278 and drives the return piston upwards thus returning the piston 228 to its original position, the air above the piston 228 escaping to atmosphere through passages 274 and 288. In a modification, Fig. 10 (not shown), the working piston of a driving unit as claimed in claim 2' of the parent Specification has a downward annular extension forming an arrow annular space which is in constant communication with the container, the pressure air in which produces the return stroke.

Abstract: 1,060,796. Textile finishing apparatus. MASCHINENFABRIK EUGEN BELLMANN G.m.b.H. Sept. 15, 1964 [Sept. 23, 1963; Jan. 22, 1964], No. 37594/64. Heading D1S. A device for pulling off stockings from forms comprises a column 1 mounted vertically on the floor or on a finishing machine, a frame 7 moveable thereon in the direction of the legs of the forms a plurality of grippers 12, 13 mounted on the frame for displacement in the direction of the feet of the forms and a carriage 27 or rods for moving the grippers. The various movements are controlled by suitable pneumatic or hydraulic means and the device is preferably associated with a depositing means (Fig. 6) as is shown in Fig. 7. In operation a packet of forms with stockings, the treatment of which is finished, is brought before the pulling off device as seen in Fig. 2 (plan view). The frame 7 with the grippers is lowered until the grippers are located in the region of the foot portions between each two adjacent forms, the heel grippers 13 are then inflated by compressed air so as to grip the stockings. The frame 7 is then lifted slightly to disengage the heel portion (grippers 13 pivots at 14), grippers 12 are then inflated to grip the tip portions of the stocking and by actuating carriage 27 in frame 7 the foot portions are pulled off. Thereafter, the frame 7 with all the stockings moves upwardly on column 1 until the upper position C is reached. Pistons 22 and 22a are then operated to force the gripping devices together so that the stockings are brought together ready for depositing. Cantilever arm 38 of the depositing device (Fig. 6) and having thereon a depositing tube 42 then moves from A to B (Fig. 8), the tube 42 engaging the stockings at about half their length. At position B spring bow 13 is turned down to grip the stockings on to tube 42 and grippers 12, 13 are deflated to release the stockings. Arm 38 then moves to position C and is lowered in height and the tube 42 with the stockings thereon is deposited in frame 55. Arm 38 then travels to position D where it picks up another tube 42 from magazine 60 ready for the next packet of stockings. For initially orientating the forms to a parallel' formation, a comb-like orienting lever 73 having prongs 74 is provided on the column 1, and to assist the entry of grippers between the forms they have a central stiffened web portion with inflatable elastic skin portions on both sides. In other embodiments a depositing plate is used instead of depositing tubes so that the stockings are deposited flat, i.e. not folded; endless belts are used for depositing the stockings; the forms are initially arranged in a segment of a circle with a central lifting device and in a further embodiment the movement of the carriage means 27 is horizontal, a combination of horizontal and vertical movement being used to remove the stocking from the former.

[Also in Divisions G3 and H1] Apparatus for sorting and conveying irregularly shaped plate entirely of magnestizable material, comprising a composite beam 1 made from cross-braced girders 2 having crossmembers 3 profiled to receive insertable frames 4 suspending plural electromagnets 5, each of diameter less than that of the smallest article but disposed over an area exceeding that over which the articles are distributed. Initially, the electromagnets are all energized and the array is lowered, e.g. by a hoist to pick up the articles to be sorted and conveyed, after which it is lifted and transported to a succession of stations at which the magnets are successively deenergized in groups to deposit selected articles upon appropriate pallets. De-energization may be effected by manual switching, or may be automatically controlled by relay switching under control of a punched tape program alternating with a similar program for lifting and transportation. When the articles are cut from a single sheet, programming may be effected by superimposing a transparent drawing of the cutting arrangement of the parts on a panel of photo-diodes positionally corresponding respectively to the plural electromagnets, and the individual article areas are successively explored by a light spot; the grouped voltage pulses from the photo-diodes being coded and transferred to tape by a punch in succession for each article to generate a de-energization programme; the transportation programme for each group being derived from a keyboard. The read-out mechanism for the tape may be mounted on the crane, and the de-energization programme derived therefrom is stored until complete; after which all selected electromagnets are deenergized simultaneously.
