Title: Sheet feeding device
IPC: B65H3/52
Filed: 1975-10-29
Abstract: 1525578 Feeding sheets XEROX CORP 29 Oct 1975 [25 Nov 1974 (2)] 44603/75 Heading B8R Sheets are separated from a pile by a friction belt 9, Figs. 1, 2 and 4, or roller mounted adjacent a side wall 7 and slightly inclined so as to register the sheets against the wall, a low-friction gate 25 engaging the edges of the upper sheets to prevent double feed and being urged against the belt by a spring 27, the assembly being supported on a carriage 15 slidable down a guide 17 as the pile diminishes and counter-weighted by a spring 23 and cord 19. The sheets are fed to pairs 40, 41 of feed rollers moving faster than the belt. The roller 41 opposite the belt is smaller than the remaining rollers 41 and its axis is nearer the pile to assist registration. A guide grid 46 pivoted to the shaft of the rollers 40 and having a part 48 resting on the shaft of the belt-driving roller 13 guides the sheets to the roller pairs and moves down as the pile diminishes. A recessed portion 33 of the gate 25 enables a sheet to be fed freely by the rollers 40, 41. The rollers 40, 41 may be stopped so as to act as front register stops.

Abstract: 1,246,821. Shearing. MOELLER & NEUMANN G.m.b.H. 20 Sept., 1968 [21 Sept., 1967], No. 44864/68. Heading B3W. A shearing line for metal sheets comprises a slitting shear 3, a cross-cut shear 5 and a roller table 4, between the two shears, which is divided preferably by a double row of idle rollers (10), Fig. 2 (not shown), into two independently driven roller tracks 4A and 4B associated with independently-operating length-measuring devices 6, 7, respectively. The devices 6, 7, which may comprise measuring rollers associated with electrical impulse counters, stop the drive of their respective roller track 4A or 4B and of an associated roller pair 23 when a predetermined length has been recorded so that different lengths can be simultaneously cut by the shear 5 from the strips into which the sheet has been slit by the shear 3. The cutting line 3a of shear 3 is adjustable transversely of the shearing line to allow sheets to be cut into strips of varying widths and deflection devices 16, 17 are provided for moving the strip travelling on the track 4A against fixed guide 9. Instead of length-measuring rollers, independently adjustable mechanical means such as gauging stops may be provided. Preferably edge-trimming shears 1, 2, one of which is movable, precede the slitting shear.

The gap 6 between a movable element, e.g. a valve stem 5, and a casing 1 is sealed by supplying sealing fluid under pressure in a liquid state, e.g. liquid sodium, to a point between the ends of the gap and cooling sections 13, 16 on each side of the feed point to a temperature below the solidifying temperature of the sealing fluid so that the latter solidifies at those sections and seals the gap. Liquid sodium is fed to the gap 6 through a pipe 8 from a container 10 and solidifies in the sections 13 and 16 under the action of cooling fins 7. The pipe and container may be heated and/or thermally insulated and the liquid sodium may be stored in the container in a protective atmosphere. The hollow valve stem 5 may be filled with thermal insulating material. In the embodiment described, the valve 4 is operated by a spindle (11), Fig. 1a (not shown), from a motor (12) to control the flow of liquid sodium, e.g. for nuclear reactor cooling systems. The sealing fluid may be potassium or tin and the working fluid may be a different fluid from the sealing fluid providing it is chemically compatible therewith.

The output from the detector 41 is fed to a controller 42, having an adjustable relationship of sensed pressure to motor speed change, and which acts on the rheostat 44 via a pilot relay 43, the detector 41, controller 42 and relay 43 being air operated. The feed screw motor 31 is provided with an overload control, limiting its torque output. Particulate material is fed to the container 13 by a fan 11 delivering from a fly-knife rotary grinder, and the outlet 27, 16, 28 of the container is vibrated by a unit 15 and connected at resilient connections 26 and 33, respectively to the container 13 and feed screw housing 29 which are rigidly mounted. The frusto-conical upstream portion 39 of the feed screw has a compression ratio of between 1À3 and 3À0 to 1, and preferably 1À5 : 1, and the downstream portion 40 is cylindrical, The material delivered from the outlet 28 to the feed screw, is agitated by a pair of oppositely inclined arms 37 provided on the feed screw drive shaft 34, and one of which has a paddle blade 38.
