Title: Fibre processing machine for producing a homogeneous web - has sets of fast running, sawtooth-surfaced cylinders
Inventor: BARBER NORMAN BENJAMIN
IPC: D01G15/04
Filed: 1977-02-15
Abstract: An installation for processing a mass of fibres to produce a homogeneous web for spinning, etc., has a group of cylinders with saw tooth surfaces, comprises two large cylinders and a small one. The first and second treatment cylinders are positioned at a tangent to each other, whilst the small working cylinder is tangential to both. The first and second cylinders rotate in opposite directions, the second at a faster circumferential speed than the first. The working cylinder runs in the same direction as the first cylinder but at a slower speed. Pref. there are three groups of cylinders one behind the other, the second cylinder of each group forming the first cylinder of the next, and the fibre is held in contact with the cylinder clothing by a metal housing having an inlet and outlet for the fibre. Works at high speed and is applicable not only to textile fibres but also to carbon, asbestos, metal and even wood fibres.

Title: Continuous operation extruding press - has reciprocating mandrel working in cyclical sequence with hollow main ram
Inventor: RIEMANN HEINZ
IPC: B21C26/00
Filed: 1977-03-08
Abstract: The press consists of main cylinder with piston. The part of the piston outside the cylinder has extended arms to which the piston rods of the retracting pistons are connected. The main piston is hollow, forms a cylinder containing piston with mandrel attached. At the beginning of the extruding cycle the main extruding ram is in the withdrawn position and filling of chamber with material in granulated or liquid form takes place, while mandrel is in the lowered position closing up tightly passage to working chamber. During the extruding operation mandrel withdraws and the material is pressed into the chamber by main rod. The final extrusion is carried out by auxiliary ram moving upwards, while mandrel is again in the lowered position. The design reduces the flow resistance of the pressed material during the extruding operation. At the same time the press is fitted with a device which ensures an accurate cycle sequence between extruding and recharging.

Title: Stress wire wedge anchorage - is positioned inside serrated ring segment stress wire wedge anchor and has narrow end areas not fitting closely against conical hole
IPC: E04C5/12
Filed: 1977-05-09
Abstract: In concrete stressing, and similar, the wedge-type anchorage is for stress wires or strands, with a wire or strand held by ring segment wedges fitting against the walling of a conical hole in an anchoring unit. The insides of the wedges are serated, or similarly profiled, for improved engagement with the stressing steel. Here there are end parts at the thin ends of the ring segment wedges (1) which do not fit against the walling of the hole (5, 6). These parts pref. extend over at least 10% of wedge length, while the hole is pref. shorter than the wedges. In this area the walling of the hole may form an angle with the end parts, opening towards the ends of the wedges. This provides min. mutual displacement between steel and wedges, and gentle transfer of stressing force from steel to wedges.

Title: Attenuated influenza vaccine contg. H3N2 strain - i.e. virus strain A/P/76/7 which is resistant to serum inhibitors
Inventor: PEETERMANS JULIEN
IPC: C12N7/00
Filed: 1977-06-14
Abstract: Attenuated vaccine against influenza contains as active ingredient a strain of attenuated H3N2 type influenza virus resistant to serum inhibitors. The strain is influenza virus strain P/76/7. Used as vaccine against influenza suitable for intranasal administration. Pref. a unit dose of the vaccine contains at least 107 DIO50 (infective dose of 50% of inoculated eggs) of the P/76/7 virus strain. The parent patent BE 819865 describes a method of obtaining stable strains of influenza virus type A (H3N2) which are resistant to serum inhibitors. Each year the serotype of influenza virus type A in the world differs slightly from the strains observed the previous year; this antigenic modification causing problems for immunisation against influenza type A. To obtain maximum effect the vaccinal antigen must be nearest to the dominant virus and thus influenza vaccines are periodically adapted to give maximum protection against these new strains, the present addition comprising such a modification.
