Title: Document handling system
IPC: G03G15/04
Filed: 1976-03-22
Abstract: 1522761 Feeding and ordering sheets XEROX CORP 22 March 1976 [24 March 1975 (2) 30 July 1975] 11452/76 Heading B8R For making pre-collated copy sheet sets in an electrostatographic copying-machine, original documents are fed over the imaging area 40, Fig. 1, on a web 12 to which they are attached by vacuum. The web is wound into rolls 50, 52, where the documents are stored between the web layers in such a way that the imaging face is concave, and the complete set of documents is fed from one roll to the other. In operation, the upper roll is in the broken line position. For loading, the roll 50 is moved to the full line position and the documents are manually placed on a registering gate 62 and, as the gate retracts, on to the web, this first run producing a proof set of copy sheets. For unloading, the roll 52 is moved to the broken line position, a tray 58 at the same time being moved to the broken line position, so that the documents automatically leave the web at the bend thereof and drop into the tray. In another form, Figs. 3-5, not shown, the web run is horizontal, and for loading and unloading one of the rolls is lowered to allow manual insertion on to the web, while a receiving tray is lowered into alignment with the straight part of the web path. In another form, Fig. 6, each document 143 is manually placed on the web outside a light-tight housing 150 enclosing the exposure zone 128, and is registered against a stop 142 projecting from a surface spaced from the web 134 to initially support the rear part of the document, and when the web moves, it carries the document away from the stop. The delivery tray 148 is fixed, and receives documents when the scroll 138 is lowered. In another form, Fig. 7 (not shown), the document carrying means is similar to that shown in Fig. 1, and there is associated with the machine a copy sheet delivery means described also in co-pending Specification. In another form, Fig. 8, the rolls are not moved, and for loading and unloading a loop is formed in the web 204 by movement of a roller 210, a fixed stop 216 being provided for manual loading. In this form, the loaded documents pass on to the upper roll without going through the exposure zone, so that no proof set is formed.

Title: Improvements relating to vacuum tubes
IPC: F42B19/10
Filed: 1928-04-18
Abstract: 289,056. British Thomson-Houston Co., Ltd., (Assignees of Benner, M.). April 21, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vacuum tubes.-In discharge tubes in which a hook or wire support 9, Fig. 3, for a filament 11 slides through an opening 8 in a rigidly mounted insulator 7 and is urged to tension the filament by a spring, pivoting of the wire 9 in the opening 9 allowed by the necessary play in the opening 8 is prevented, and consequent lateral movement of the filament is limited, by a guide 18 slidably engaging the end of the wire 9 remote from the filament. An anode 2, Fig. 1. may be supported on a split metal collar 3 from one end of the tube and a grid and filament may be supported from the opposite end. An insulator 4 on the collar 3 has openings engaging grid-supporting rods 6 to prevent relative lateral movement between the grid and anode. Insulators 7, 18 fixed to the rods 6 by metal beads 20 and spaced by sleeves 19 have aligned openings 8, 21 through which the filament-supporting wire 9 passes. A cylindrical spring 17 tensioning the filament 11 is arranged between plates 12, 15 with downwardly and upwardly turned flanges 13, 16 respectively, the plate 12 being secured to the wire 9 by a welded plate 14 and the plate 15 resting on the insulator 7.

Title: Improvements in or relating to hydraulic piston machines especially for high pressures
IPC: F04B11/00
Filed: 1960-04-01
Abstract: 937,521. Reciprocating pumps. ROBERT BOSCH G.m.b.H. April 1, 1960 [April 3, 1959], No. 11528/60. Class 102(1). [Also in Group XXIX] In an axial piston type pump to reduce noise in the opening and closing of the pump working chambers, the or each working piston functions as a slide valve and is acted upon by resilient means interposed between the effective pressure surface of the piston and the member driving the piston. As shown in Fig. 1, a swash-plate 7 mounted on a drive shaft 4 acts on pistons 8 slidably mounted in bores 9 in a fixed cylinder block. Each bore communicates with a suction passage 10 through an annular groove 11 and co-operates at its end with a non-return discharge valve 12. The pistons 8 are formed in two telescopic parts 15, 17 between which are interposed spring washers 19. At the commencement of the delivery stroke sudden rise in pressure is avoided due to a counter pressure acting on the piston surface 16<SP>1</SP> which retards movement of the piston part 15 relative to the part 17. Grooves 26 formed in the piston edge permit a small quantity of liquid to enter the bore 9 after the piston edge has passed the end of the annular groove 11 to further assist in the resistance to movement of the piston part 15. The grooves 26 also permit during suction a small intake of liquid into the bore 9 prior to the full opening of the bore to the annular groove 11. In another embodiment, the spring washers 19 are omitted but the piston which abuts the swash-plate is stated to be made of a material having sufficient resilience to provide an effective resilient means between the effective piston surface and the member driving the piston.

Filed: 1918-07-15
Abstract: 132,836. Cammell, Laird, & Co., Carter, Sir G. J., and Jones, E. V. July 15, 1918. Piston apparatus for discharging receptacles.-In apparatus for forcing liquids and semisolids, comprising a piston adapted to be moved in a barrel by turning the screwed pistonrod in a fixed nut in the head of the barrel, the nut 14 is split and detachably secured in the barrel head, so that when it is withdrawn, it can be opened and slid from one end of the pistonrod 9 to the other. Preferably, the nut is in halves hinged at 15 in a line beyond the screwed part of the. nut, and is so shaped that, when closed, its exterior is cylindrical and fits the head of the barrel 1, and is held in place by means of pins 16 engaging L-shaped slots in the barrel. The liquid is discharged through a screw - threaded nozzle 4.

Title: Piston for rotary piston internal combustion engines
IPC: F02B55/02
Filed: 1973-03-09
Abstract: 1378476 Rotary piston internal combustion engines AUDI NSU AUTO UNION AG and WANKEL GmbH 9 March 1973 [11 March 1972] 11566/73 Heading F1F A multi-apex piston for a rotary piston internal combustion engine of the trochoidal type has a pre-formed groove reinforcement 2 of wear-resistant material at each apex, the remainder of the piston 1 being cast around these reinforcements 2. Each reinforcement 2 has a generally U-shape and includes projections 19, 20 and bulge portions 10, 11 to prevent relative radial and axial movement between the reinforcement and remainder of the piston. Each reinforcement also has an axial groove 3, 4, 5 for a seal, each end of the axial groove having a part-circular increased diameter portion 12 for a corresponding link block for sealingly inter-connecting the axial end seals and apex seals. The portions 10, 11 have openings 17, 18 which are larger than grooves 13, 14 for the axial end seals so that during casting, the material of the remainder of the piston fills these openings. Thus, when the grooves 13, 14 are made they may be carried through the reinforcement without actually involving cutting of the reinforcement. The reinforcement may be itself made from casting, sintering from powder, or in the form of an extrusion. The remainder of the piston 1 is made of a light alloy.
