Title: Improvements relating to overlapping joints in ships or other structures
IPC: C09J163/00
Filed: 1957-10-18
Abstract: 910,582. Bolting; locking nuts and bolts. RITCHIE, J. Jan. 19, 1959 [Oct. 18, 1957], No. 32684/57. Class 89 (1). [Also in Group XXII] Sheet metal members, e.g. in ships, tanks, &c., are joined by passing the shank of a bolt through corresponding holes, filling the clearance between the shank and the side of each hole with a cold-setting resin composition and clamping the members together by screwing a nut on to the bolt. The composition includes an epoxy and a polyamide resin and a filler, e.g. calcium plumbate, silica, china clay, powdered zinc or powdered aluminium. The shank of the bolt is coated with the resin composition before passing the shank through the holes. When joining aluminium to steel, the resin reduces or avoids the occurrence of electrolytic action. The head of each bolt may be slotted to receive a screwdriver or may be provided with a rectangular projection for holding the bolt against rotation by engaging said projection with a suitable tool while the nut is tightened. The projection is glued to the bolt head or joined by a reduced section so that, after tightening the nut, additional torque applied to the tool shears off the projection.

Title: Charge-coupled arrangements
IPC: H01L29/762
Filed: 1973-07-11
Abstract: 1432987 Charge-coupled semi-conductor devices SIEMENS AG 11 July 1973 [16 Aug 1972] 33091/73 Heading H1K In a charge-coupled device the semi-conductor material beneath the gaps between adjacent electrodes is counter-doped, e.g. by ion implantation or diffusion, with impurities of the opposite conductivity type to those of the initially homogeneously-doped semi-conductor body. This facilitates transfer of charges between adjacent electrodes which are spaced further apart than in conventional chargecoupled devices. The counter-doping may be to a sufficient extent to convert the counter-doped material to the opposite conductivity type, in which case during operation charges are transferred between adjacent electrodes as majority charges. Alternatively the counter-doping may be sufficient only partially to compensate the original dopant concentration. Three methods suggested for injection of charge into the device are by means of a p-n junction, light or a surface avalanche effect.
