Patent LV-10128-B (LV)
Title: Pipe, consisting of two half-hulls
Inventor: BAUER PETER
IPC: F16L9/22
Filed: 1993-03-02
Abstract: This invention is composed of two parts of a pipe, cut lengthways, and connected in such a way that between the contiguous surfaces of both parts there is a mortise with densification unit in one of them and a spring, similar to a fishing hook, in the other. This invention suggests forming the spring (2a) with at least one slip surface (G), which, when moving into the mortise and sliding through it, can slide along the densification unit (3, 4). The movement direction of the surface of the spring's slip (2a) is always perpendicular to the direction of the force movement of the densification unit. Several versions of forming and placing the densification units are offered. For example, in the mortise between the contiguous surfaces of both parts, one cell is planned for the placement of the spring (2a). The placement of a densification unit (3), e.g. densification string is suggested for the placement of the other cell. In the process of the pipe leakage (for example, when yield power is created and the inner pressure of the pipe increases) the densification unit presses from aside to the spring with slip surface and remains outside the lines of force, which cover the walls of the pipe. The offered pipe remains hermetic in water and air environments even in conditions of high inner pressure.<IMAGE>

Abstract: A disc cylinder lock - key - combination, comprises a cylinder housing (1) and inside thereof, a turnable inner cylinder (2) enclosing a stack of discs including a number of locking discs (3, 4). The locking discs (3, 4) are turnable by means of the key (12) of the lock into a releasing position of the lock mechanism. The key opening (6, 7) of the locking discs (3, 4) is so formed that it comprises at least one internal protrusion (21) narrowing a part of the key opening (6, 7). The adjacent sides of the protrusion (21) can be substantially perpendicular with respect to each other. One side of the protrusion (21) forms a combination surface (22) arranged to cooperate with a corresponding combination surface (27) in the key (12) for determining the turning movement of a locking disc (3, 4) to open the lock and the other side of the protrusion (21) forms a return surface (23) for the locking disc (3, 4) on which the key (12) acts by means of a guiding element (14) when returning a locking disc (3, 4) into its locked position. <IMAGE>

Abstract: 1,193,904. Polymer metal complexes. CESKOSLOVENSKA AKADEMIE VED. 24 May, 1968 [25 May, 1967], No. 24837/68. Heading C3P. [Also in Division G2] A polymer-metal complex is formed by contacting a polymer system containing nitrile groups and groups capable of forming the anions -OSO- 2 , -OSO- 3  or -OPO<SP>2-</SP> 3  in ionizing media. both groups being attached to macromolecular main chains, with silver or copper cations. The ionizing media may be water. The groups may be borne by the same or different macromolecules. The polymer system is preferably a copolymer of acrylonitrile with vinyl sulphonic acid, styrene sulphonic acid or an alkali metal salt of one of these acids. The complex metal cation may be reduced thus forming a dispersion of the free metal in the copolymer. The free metal may be reconstituted by contacting the copolymer with silver or cuprous cations. The copolymer complex containing silver cations may be treated with a halide solution, and this polymer system containing dispersed silver halide may be contacted with silver or cuprous cations. In the examples, acrylonitrile, sodium vinyl sulphonate and optionally ethylene glycol bis-methacrylate or acrylamide, are co-polymerized using a catalyst comprising potassium pyrosulphite and ammonium persulphate with a copper sulphate activator. The polymer is formed into a membrane layer or filament which is treated with silver nitrate or acetate solutions or a solution containing cuprous ions. In other examples silver nitrate is added to polyethylene- or polystyrene-sulphonic acid and this is mixed with polyacrylonitrile; alternatively the two polymers are mixed and together added to a silver nitrate solution. In, a further example, a nitric acid solution of polyacryonitrile is treated with silver nitrate and then reacted with an acrylonitrile-ethylenesulphonic acid copolymer.
