Patent GB-1584928-A (GB)
Title: Devices for use in connecting pipes
IPC: E21B17/046
Filed: 1978-04-05
Abstract: The pipe joint has a clamping sleeve (1), slit several times over the periphery, and a threaded bolt (2) which can be inserted into the bore of the clamping sleeve (1) and is intended for expanding the latter. The pipes to be joined, which in the area of the spigot or socket end have radial bores distributed at equal angles over the periphery and in alignment with one another, accommodate the clamping sleeve (1) therein. By virtue of the fact that the pipe joint comprising only two elements is on the one hand characterised by simple assembly and reusability and is releasable and adjustable, a firm connection of the spigot or socket end of the pipe is obtained on the other hand when the clamping sleeve (1) is expanded. <IMAGE>

Title: Mold for Casting Concrete Hulls.
Inventor: LARSEN EDWARD ALFRED
IPC: B63B5/16
Filed: 1918-08-15
Abstract: 131,152. Larsen, E. A. Aug. 15, 1918. Concrete ships.-A mould for casting concrete ships is preferably constructed of reinforced concrete, and has means for applying water pressure between the vessel and mould to remove the vessel. The mould 4 may be constructed below the sea-level behind gates 6 or as a floating dry dock. The end of the mould is formed of hollow hinged members 5, or of floating caissons, which caissons may also be used for the sices of the mould. To prevent the hull adhering to the mould it is lined with water-proof paper with or without a backing of soluble material. An inner lining 12 may be used supported by strips 13, 15 separated by lubricated cables 14, further cables 20 passing through holes 11 being used to pull the lining away from the hull when the cables 14 have been withdrawn. The inner lining may be removable in sections and may be two or three feet away from the outer mould to facilitate access and to construct smaller vessels. The surface of the mould is corrugated, as shown at 19, to ensure an even distribution of water pressure when lifting the vessel from the mould. Hydraulic jacks may be used below the keel to assist lifting.

Title: Improvements in attachments for discharging contents from vessels
IPC: B63B27/24
Filed: 1920-05-15
Abstract: 153,853. Heffernan, M., and Glancy, J. C. May 15, 1920. Tapping.-An attachment for discharging the contents of petrol &c. containers or like vessels, comprises an inner tubular part 1 which terminates in a cutter 9, and an outer part 3 beyond the flange 2, formed as a pouring spout, &c. The parts 1, 3 may be integral or separate. A spring coil encircles the tube 1, the forward end 5 of which, formed as a cutter point, and the end coil 12 are both fixed to the tube by brazing &c., the rear end 8 being free to expand and covered by a resilient ring 14, within which in some cases is a protective ferrule 17. The cutter 9 first forms a hole in the wall of the vessel to be emptied, and on further rotation of the attachment the cutter point 5 enlarges the hole so formed, some of the forward turns of the coil now passing through into the interior of the vessel, compressing the resilient ring 14 between the wall of the vessel and the flange 2, thus giving a tight joint. The part 1 is slotted at 18 under the ring 14 to permit the drainage of a nearly empty vessel.

Abstract: 672,253. Mining-machines. HENKEL, K. May 23, 1949. [May 22, 1948] No. 13714/49. Class 68 (i). Mining-apparatus in which at least one cylinder 17 is mounted on a frame 1-4 so that it may be moved relative to the frame by rack pinion gearing 8, 9, the movement being transversely of the longitudinal axis of the cylinder. The piston rod 15 carries at the outer end a fluid operated hammer 16 which acts on a chisel body 17 that strips the mineral from the seam when it is advanced on expansion of the piston-cylinder assembly. At the completion of the stripping stroke, the ram is retracted and the cylinder moved by the rack and pinion gearing across the frame into a position ready to strip the next layer from the seam. During each stripping operation, a jack unit 22 expanded between the floor and the roof and positioned at the rear of the cylinder absorbs the thrust of the cylinder. Extensions can be fitted to the frame in order that the lateral traverse of the cylinder may be increased. When more than one cylinder is used they are mounted vertically above one another.

Title: Character recognition devices
IPC: G06V10/88
Filed: 1961-04-17
Abstract: 979, 492. Automatic character reading. BAIRD-ATOMIC Inc. April 17,1961 [April 29,1960], No. 13864/61. Heading G4R. A device for identifying an unknown pattern comprises focusing means having an optical axis and a centre plane means for placing the unknown pattern at second plane spaced from the centre plane, an array of known patterns placed at the centre plane an array of electrical light detecting means at a plane critically defocused plane spaced from the conjugate plane of the second plane, means for illuminating the unknown pattern so that light passes from it through the focusing means and each of the known patterns to the detecting means, the light received by each being dependent upon the match between the unknown pattern and the corresponding known pattern. The principle of the invention is explained with reference to Fig. 1 in which light from an unknown pattern 13 is passed through focusing lens 10 and a shaped stop 16 to fall on a defocused plane 20 beyond the focused plane 14. The image 21 is a blurred area having a peak of light intensity at its centre, the brightness of the peak being dependent upon the match between the pattern 13 and the opening 18 in the stop. In Fig. 4 the character on transparency 32 is illuminated by a lamp 40 shining through a ground glass lens 49 and lenses 42. The optical system comprises lenses 24 having a centre plane 44 at which is placed an array of positive and negative images 46, 48. At the defocused position corresponding to each image is a photomultiplier. The outputs of corresponding positive and negative images are subtracted and the differences are applied to a threshold device set to give an output for the matching character. The positions of the known and unknown characters may be reversed. Mechanism is provided to bring characters successively into the comparing position by moving the transparency 32 horizontally and vertically.

Filed: 1973-03-23
Abstract: 1376098 Soldering INTERNATIONAL BUSINESS MACHINES CORP 23 March 1973 [26 April 1972] 14056/73 Heading B3R A method of bonding a semi-conductor chip to contact elements which carry an excess of solder comprises bringing into contact with the solder on the elements a chip simulation member which has a solderable surface layer and has the same heat transfer characteristics as the chip, heating the solder to reflow temperature, removing the member whereby the excess solder is removed and then solder reflow bonding the chip to the contact elements. A plurality of contact elements 10, Fig. 2, for an integrated circuit chip are formed on an alumina substrate 12 by screening a conductive pattern of a solderwettable silver-palladium paste on the substrate, depositing a glass dam 13 on the conductive pattern and then contacting with molten solder. The solder lands 14 thus produced are of hemispherical shape and do not carry an excess of solder. However after bonding a plurality of chips to the substrate testing of the chips and connections is carried out and any chip shown up as not meeting the test requirements is removed. Removal may be effected by the method described in Specification 1,372,144 involving heating the chip by a microflame to a solder reflow temperature level which is sensed by infra red sensing means whereupon the flame is extinguished and the chip removed. The solder lands 14 left after removal of a faulty chip may carry excess solder, Fig. 3, (derived from the solder pads of the chip itself) with attendant danger of short circuiting adjacent contact elements. Excess solder is therefore removed by bringing a member 16, Fig. 4, comprising a body 18 of silicon or titanium and having a surface coating of, e.g. copper 20 covered with a thin flash of gold 22 (or alternatively a surface coating of chromium/chromium-copper/copper/gold) into contact with the solder 14 and heating by a method and heating cycle corresponding to that for removal of a chip, to solder reflow temperature before removing the member 16. The member 16 is held by a vacuum pencil 24. The heating cycle is controlled to ensure that adjacent chips are not heated sufficiently to cause reflow of their solder connections. Removal of the member 16 leaves the solder contacts 14 in satisfactory condition for reflow bonding of a replacement chip.
