Title: Method and apparatus for setting mine roof pins
IPC: E21D20/00
Filed: 1971-07-09
Abstract: 1340373 Roof pins PIN-SET CORP 9 July 1971 32288/71 Heading F2H A pin to be pressed steadily into a mine roof has an elongate shank 41 with a head 42 at one end and a pointed tip 43 at the other, a first portion 44 of the shank having a greater peripheral dimension than a second portion 45, the relative lengths and dimensions of the two portions determining the force required for insertion and the pull strength of the installed pin. In Fig. 1, the first portion is adjacent the tip. In a modification, Fig. 4, a tapered rear end 57 of the first portion 53 is encircled by an internally tapered split ring 55 having the same outside diameter as the first portion 53. After installation, a pull on the pin causes the tapered end 57 to expand the ring 55 to increase the grip on the rock. In Fig. 7, the first portion 80 comprises numerous protuberances on the shank and the rear part of the tip 77. In Fig. 8, the enlarged first portion 84 has longitudinal grooves 86 which extend into the rear part of the tip. In Fig. 9, not shown, the first portion comprises a helical rib (94) extending at least one turn about the shank adjacent the tip, with a lead-in section on the rear part of the tip. In Fig. 3, not shown, the first portion (72) is a frusto-conical portion immediately behind the tip. In Fig. 2, not shown, the first portion (64) is a parallel shank portion adjacent the head, the smaller second portion (65) being adjacent the tip. For installation the pin 40 is mounted in an hydraulic cylinder 13, with its head 42 seated in a piston 20 and washers 46 to centre it in the cylinder. The open end 14 of the cylinder is held against a wood block 35 pressed against the mine roof 11 by hydraulic jacks 25 having feet 32 that seat on the mine floor 12. The pressure applied on the block 35 by the jacks 25 forces the roof strata tightly together. Pressure fluid is supplied at 16 to the cylinder 13 to force the pin 40 steadily into the rock. The washers 46 are slidden along the shank until they bear between the head 42 and the block 35. The cylinder 13 pressure is increased after full penetration of the pin 40, to further compress the roof strata. The piston 20, and then the jacks 25, are finally retracted. A safety switch 36 prevents pressurization of cylinder 13 until the jacks 25 have pressed the block 35 firmly against the roof.

Filed: 1970-06-09
Abstract: 1345709 Feeding and delivering sheets CROSFIELD BUSINESS MACHINES Ltd 2 June 1971 [9 June 1970] 27902/70 Heading B8R Sheet feeding apparatus includes a chamber extensible and contractable by a movable section in response to a reduction of pressure within the chamber, an aperture in the section serving to hold a sheet at a first station upon withdrawal of air from the chamber, further withdrawal causing the section to move and thereby contract the chamber resulting in transfer of the sheet from the first to a second station. The chamber may comprise a sleeve 3 slidably mounted on a pivoted tube 1. Application of suction via a valve 15 attracts the topmost sheet from a pile 17 to the sleeve 3 which then slides up the tube 1, linkage 10, 8 causing the chamber to pivot into a vertical position where a stripper plate 20 or pinch rollers 21 urge the sheet into a stack 18, suction being simultaneously released as a duet 6 in sleeve 3 coincides with a duct 5 in the tube 1. An arm on the sleeve 3 operates a ratchet or toothed wheel for raising the pile. Alternatively the chamber may comprise the periphery 31, side walls (36), Fig. 4 (not shown), and an end wall 35 of a sector of a cylinder rotatably mounted about a pivot 32, together with a fixed wall 37, withdrawal of air via duct 33 attracting a sheet from a pile 39 to apertures 40 and grooves (40a), Fig. 3 (not shown), on the sector periphery and causing rotation of the sector to a second station where a stripper 43 deposits the sheet in a stack 42, a depression 41 releasing the suction when it reaches the end wall 37. A vacuum port 44 may assist separation. In a third embodiment, two symmetrical chambers 54, 58, Fig. 5 are formed between a rotatable cylinder 50 and an internal, eccentrically mounted cam 51 which controls the movement of two interconnected vanes 59a, 59b, the vanes defining ends of the chambers. Suction applied via a duct 53 in the cam attracts a sheet from the bottom of an upper pile 55 to a chamber aperture 56 in the cylinder wall and causes the cylinder to rotate thereby contracting the chamber. A stripper 62 then removes the sheet from the aperture to a lower stack 57 after a half revolution of the cylinder whilst an aperture 61 in the second chamber attracts the next sheet from pile 55 to repeat the cycle. The vanes 59a, 59b may be pivoted.

Title: Method for making cards and cards obtained by this method
IPC: B29C63/02
Filed: 1996-11-12
Abstract: The invention concerns a method for making smart cards by rolling. A first synthetic sheet (1) is first smoothed by hot pressing against a first smoothing plate (4). Likewise a second synthetic sheet (2) is smoothed against a second smoothing plate (5). Without being unstuck from their smoothing plates, these two sheets are rolled with other layers (3, 6, 7), said synthetic sheets (1, 2) serving as external layers. One of the smoothing plates may comprise a three-dimensional pattern to be relief printed on the synthetic sheet. The rolling is carried out by cold pressing the different layers (1, 6, 3, 7, 2) which the laminated card comprises between the two smoothing plates (4, 5). After being rolled, different cards with adapted dimensions can be cut out from the laminated sheets. The invention is advantageous in that the same plates (4, 5) are used for the hot pressing and the cold rolling. The external surface of the synthetic sheets (1, 2) thus remains protected between these two operations and the cards have better inherent flatness.
