Title: Improvements in pneumatic sheet-separating apparatus
IPC: B65H3/08
Filed: 1951-11-16
Abstract: 712,337. Feeding sheets. AKTIEBOLAGET DUX. Nov. 16, 1951 [Dec. 21, 1950], No. 26962/51. Class 100 (1) Sheets are conveyed from a pile 1 to a conveyer by suction nozzles which are sucked inwardly of their holders 18 when they contact a sheet, the nozzle end plate 21 of each nozzle being tiltable to accommodate irregularities in the upper surface of the sheet pile, and the nozzle holders 18 being capable of turning individually against the action of a spring. As shown, a number of units each comprising a body 10 having passages 11, 12 therein to which suction and compressed air pipes 15, 16, respectively, are connected, is pivoted at 9 to a carrier 3 adjustably secured on a transverse rod 2. The body 10 is urged downwardly by a spring 8 against a stop on the carrier 3. The holder 18 is screwed into the suction passage 11, and has a guide 19 screwed therein in which slides a nozzle extension 20. The nozzle comprises a plate 21 grooved at 22 to accommodate, if necessary, an additional rubber nozzle 25. When the plate 21 is lowered on to the top sheet of a pile, suction builds up in the passage 11, and the plate carrying the top sheet is sucked upwardly until it presses a packing 23 thereon against the guide 19. The transverse rod 2 carrying the suction units then rises, moves to the left to release the sheet over a conveyer, then descends and returns be'ow the sheet to the original position above the sheet pile. Compressed air is blown from the passage 12 through smaller passages 26 in the body 10 to assist sheet separation. Since each nozzle body 10 is urged downwardly by the spring 8, it can adapt itself to the irregularities of pile height by movement about the pivot 9. Further, the extension 20 is a slack fit within the guide 19 whereby the suction plate 21 can tilt slightly to accommodate irregularities in the surface of the top sheet of the pile.

Title: Grinding wheel
IPC: B24D5/06
Filed: 1971-04-19
Abstract: 1348305 Abrasive tools M C SHAW 19 April 1971 [15 April 1970] 26986/71 Heading B3D A grinding wheel assembly comprises a plurality of grinding wheel segments 56, Fig. 2, arranged about the periphery of a wheel in a recess 50 whose opposed side walls 46, 48 converge towards one another in a radially outward direction and co-operate with complementary side faces on the segments or on wedge members abutting the side faces of the segments, such that centrifugal force during rotation of the wheel produces at at least one of said side walls a resultant force having an axial component which produces a compressive clamping force in the grinding segments, the segments (and the members, if present) being spaced from the bottom of the recess whereby substantially no compression clamping force can be applied to the segments prior to rotation of the wheel. The opposed side walls 46, 48 are formed on annular members 40, 44 which are spaced apart by a member 42 and secured together by bolts, the spring member having a thickness such that the side walls, when the assembly is stationary, do not clamp against the segments but apply a compressive clamping force due to centrifugal force acting on the segments when the assembly is rotating. As described, the assembly has twelve segments 56, each of which has a trapezoidal cross-section, and the segments may have the same or different abrasive and may be separated by dummy segments. The annular members 40, 44 and spacer 42 are received between opposed faces 34, 36 on a disc 16 secured to a drive shaft 12 and a disc 27 keyed to the shaft and clamped towards disc 16 by a nut 24. In another embodiment, a wheel member 70, Fig. 5, is secured to a shaft 72 and its rim has a recess formed with opposed side walls 82, 84 which converge towards one another in a radially outward direction. The side walls engage wedge members 92, 94 which are urged radially outwards by resilient 0-rings 97, 98, 100 and have planar surfaces 96 engaging planar surfaces of grinding segments 86 of rectangular cross-section. The 0-rings, or screws (114, Fig. 8, not shown) of another embodiment, act on the wedges so that they apply an initial clamping force when the wheel is stationary. In a further embodiment, one of the side walls is perpendicular to the axis of the shaft and wedges are only provided at one side of the segments. Flange members 102, 104 may be secured to the sides of the member 70 to form troughs 106, 108 for coolant which can pass through passages 110, 111 and gaps between the grinding segments to their operation surfaces.

Abstract: 1,236,319. Shower cabinet bases. N. R. BERGMARK. 28 May, 1969 [30 May, 1968], No. 27105/69. Heading A4N. A shower cabinet base 1 comprises a floor 3 arched upwardly towards a central region of the floor from a gutter 5 extending along at least the greater portion of the periphery of the floor, the gutter having a water outlet 11. The base is generally square in plan view, the gutter being substantially U-shaped in section with an inner wall integral with the periphery of the floor and the gutter extending around three or four sides thereof. The bottom of the gutter may be horizontal or may slope towards the outlet which may be located in a corner of the gutter or in the centre of the inner gutter wall of one side, this side being the side opposite that side not having a gutter when the gutter extends along three sides. An outer gutter wall extends higher than the inner wall and may have a step 9 or a groove 10 formed on the inside or outside surface respectively for supporting cabinet walls. The base is supported on legs 15, 17 screwed into sockets 13 formed integrally with the inner corners of the gutter and with the central region of the floor 3 respectively, the legs being screwdriver adjusted through holes in the floor covered by plugs (19), Fig. 1 (not shown), and 21 respectively, integrally formed stiffening ribs 23 extending between the central socket and the corner sockets. Alternatively the base may be supported on a cushion of foamed plastics material placed on an adjustable stand and having an upper surface shaped to contact substantially the entire under surface of the floor 3, the ribs 23 being of simpler construction or dispensed with. A gutter portion at a cabinet entrance may form a guide for the lower part of an entrance covering curtain. With a gutter around all four sides, the gutter on one side may be interrupted or shallower at one point for the passage of a hose connected to outlet 11.

Title: Overload safety device
IPC: F16D9/00
Filed: 1975-06-26
Abstract: 1512846 Breaking-pieces DEMAG AG 26 June 1975 [26 June 1974] 27108/75 Heading F2X In an overload safety device, a load transmitting member embracing juxtaposed projections on two axially aligned rotatable parts is arranged to fracture when an overload occurs, and a surface on at least one of the parts is so arranged as to wedge the member outwards following its fracture. In one particular embodiment, shaft components aligned so as to rotate about an axis 11 are provided at their ends with shoulders 5 which abut along a radial plane (Fig. 2 being a section in this plane). Each shoulder 5 has three equiangularly spaced semicylindrical projections 7a, 7b forming, when the shoulders 5 are are in abutment, three cylindrical bosses held together by pre-stressed steel rings 8. The rings 8 are so designed that they fracture when subjected to a predetermined torque. Each of the shoulders 5 is also shaped so as to define three hump-like protrusions 10 which alternate with the projections 7a, 7b. Each of the protrusions 10 is defined by an arcuate surface 12 between a pair of planar surfaces 9. In two modifications, the arcuate surface merges smoothly with the planar surfaces (Fig. 3, not shown) and each protrusion is formed by two intersecting planar surfaces (Fig. 4, not shown), respectively. Referring now to Fig. 5, the ends of the planar side surfaces of the projections 7a, 7b are rounded as at 16, 17 in order to ensure that the ring 8 is not sheared by contact with a sharp edge during slight displacements of the projections 7a, 7b. The risk may be reduced still further by reducing the thickness of the ring 8 adjacent the ends of the planar side surfaces (Fig. 6, not shown). When the torque between the two shaft components exceeds a predetermined value, the rings 8 break and the projections 7a rotate relative to the projections 7b. Because the protrusions 10 between these projections 7a, 7b have a maximum radial extent at least as great as that of the projections, the broken rings are cleanly stripped away without becoming entrapped between the facing surfaces of the shaft components. Sometimes the magnitude of the overload is insufficient to break the rings 8, but does cause them to plastically deform and allow the shaft components to slip in relation to each other. By providing the projections 7a, 7b with graduated scales (Fig. 7, not shown), it is possible to determine the magnitude of the overload, provided that the physical characteristics of the rings 8 are known.
