Patent GB-857173-A (GB)
Title: Bit weight applicator
IPC: E21B44/00
Filed: 1959-04-16
Abstract: 857,173. Borehole apparatus. JERSEY PRODUCTION RESEARCH CO. April 16, 1959 [May 14, 1958], No. 13047/59. Class 85. An hydraulically operated device for applying cutting pressure to a drill-bit comprises a piston assembly connected to the drill-bit and a cylinder with expanding wall-sections which can be locked in the well-casing. The piston assembly-which forms the upper part of the device and is shown in Fig. 1A is formed by an inner mandrel 10 which is supported by a drill string 12, and which enters a cylinder 46 through a bearing 26 and a packing gland 28, and a piston 38 which is secured to the mandrel and slides in the cylinder 46. A port 49 in the wall of the mandrel connects the cylinder with the bore of the mandrel. A second piston 60 is attached to the mandrel at a lower point and runs in a cylinder 62 which is connected with the mandrel bore by a port 72. The intermediate part of the device (Fig. 1B) comprises individual rubber anchor blocks 64 moulded around a metal core which can be expanded by internal pressure so that the blocks grip the well casing, there are longitudinal passages between the individual blocks to permit circulation of the drilling fluid. In operation the device is lowered into a bore and drilling fluid is pumped down the drill-string to expand the anchor blocks and subsequently act on the pistons 38 and 60 to apply pressure to the drill bit. An automatic bottom device 93 (Fig. 1c) which ensures that the anchor blocks lock before the mandrel is allowed to move longitudinally of the cylinder comprises buttress-threaded segments 94 which engage a similiar thread on the mandrel 10. The mandrel can only be released from the segments by right-hand rotation which screws the mandrel out of the segments, but since they are spring-loaded the mandrel can be re-engaged with the segments by an upward movement of the drill-string.

April 27, 1956, No. 13061/56 Classes 20(2), 20(4) and 87(1) A floor is formed from a plurality of multi-cellular sheet metal units assembled side-by-side and emd-to-end upon a supporting framework. Each unit comprises an upper corrugated sheet 12 and a lower flat sheet 14 connected together such as by welding to provide a series of cells 16 which in the assembled floor may be used as conduits for electrical wiring. The sheets 12, 14 are flush at the trailing end 26, but sheet 12 extends beyond sheet 14 at the leading end 24. At this end the upper and lower walls 28, 34, of the corrugations are offset upwardly, and the side walls 30, 32 are offset outwardly to allow the leading end 24 of one unit to overlap and embrace the trailing end 26 of an adjacent unit when assembling the floor. Openings 38 in the lower walls 34 of the corrugations, enable adjacent sheets to be welded together and to a supporting girder. The lower sheet 14 has marginal portions 20, 22 to enable units to be connected in side-by-side relation. Specifications 400,924, 420,062 and 657,839 are referred to.

For producing and following a desired curve light is projected from a source 11 through or about an object such as a circular aperture 21 to form an image 15 in a plane and the angle of projection between the object and the plane is adjusted until the boundary of the image forms the desired curve, the plane then being scanned by a light sensitive device 16 whose linescanning motion is arrested or reversed in response to a change of illumination. The scanning raster of the device 16 has its linescanning motion parallel to an arm 17 supporting the device and its field scan motion at right-angles to it. The line scan motion is reversed on a change of illumination above a threshold value at both the image boundary and a datum line 20 whilst the field scan movement may be continuous, or may be operative only at each reversal or alternate reversal of the line scan.

Title: A continuous method for the treatment of compressed fibrous material with gaseous substances
IPC: F26B17/28
Filed: 1964-04-02
Abstract: 1,010,025. Textile treating apparatus. UNISEARCH Ltd, M. CHAIKIN, and A. SAMSON. April 2, 1964 [April 5, 1963], No. 13655/64. Heading D1L. [Also in Division F4] In a method of treating non-woven fibrous material the fibres are conveyed in a compressed state between two porous conveyers and are subjected to the action of atmospheric or conditioned air generally directed transversely to the direction of movement of the fibrous layer, the degree of compression of the fibres being such as to reduce relative movement of the fibres to a practical minimum whereby the tendency of the fibres to entangle is substantially reduced. In the arrangement shown fibrous material is placed on roller 1, which is partly wrapped around by an endless porous conveyer 2, and is conveyed and compressed between belt 2 and porous drum 3, and thence to delivery roller 4. The compressive force between the belt and the drum is induced by the tension in belt 2 produced by pivoted tensioning roller 5. Gaseous fluid may be applied under pressure to the fibrous material from within or from outside porous drum 3. From the outside, manifold 8, which may be partitioned to supply different gaseous substances of different conditions, distributes the fluid under pressure into pressure bore 9 so that it impinges on and passes through the moving fibrous layer into drum 3 from whence it is drawn via hood 10. For treatment from within drum 3 gaseous fluid is supplied through central pipe 12 to a manifold 13 which allows fluid to impinge on the moving compressed fibre layer. The treated material may be removed from belt 2 by a rotating heater 14. Alternatively the material may be conveyed between two porous conveyers.

Interconnected pipes 19, 15, 11 for the transfer of fluid cargo, e.g. from ship to shore, are arranged in a counterbalanced lever system by making the pipe joints 18 and 14 pivotal and balancing the combined weight of the movable pipes 15 about the pivot 14 on fixed pipe 11 in such manner that their total moment about this pivot is at all times substantially equal to that of the counterweight system, the maximum permitted out - of - balance moment being 5% of the load moment. The balancing may be achieved by a counterweight 25 movable in an orbit about a point on an extension arm 16 rigid with the pipe 15. In the preferred form illustrated, two counterweights are used-a fixed weight 17 on the extension 16 and an orbitally movable weight 25 whose centre of rotation coincides with the pivot 14. The weight 17 is set to counterbalance the pipes 15, 19 with the latter hanging vertically and the weight 25 in the broken line overcentre position. An endless cable or chain 26 connects pulleys or sprockets 23 and 27, the former of which is attached to weight 25 and the latter to pipe 19, so that the weight moves with the latter pipe to retain counterbalance. The magnitude and/or position of the weights may be varied to allow for the weight of material in the pipes. Specification 978,762 is referred to.
