Title: Bending plastic tube in one layout without affecting cross=section - by heating tube between two jaws, opening jaws and moving tube between two moulding jaws, cooling with water and blowing air through to dry
IPC: B29C53/08
Filed: 1992-05-14
Abstract: Plastic tubes are bent by warming them first, placing them into a device with the required bent shape and cooling them. A tube concerned is heated to a temp. at which it can be plastically formed. It is placed in a tubular bore formed by two channels in the adjacent faces of two jaws which can be together/apart, the length of these jaws having the desired shape and radius. When bent the tube is cooled by flow of coolant while it still remains in the bending tool. The two jaws are then sepd. to enable the tube to be removed. ADVANTAGE - All the operations concerned take place in the one set-up. The bending operation is not a function of the skill fo the operator. Significant changes on the cross-section of the tube are not produced at the bends, even if they have small radii of curvature.

Title: Process for producing oriented tubular films from polypropylene with improved strength and transparency
IPC: B29C48/10
Filed: 1993-03-18
Abstract: Previously known processes of this type are well suited for HD-PE and PP, but require a very high energy consumption and high investment costs. Processes which are predominantly suitable for fast-crystallising linear HD-PE, but always produce opaque films with limited improvement in strength, are also known. The invention is based on the object of providing an improved blown film extrusion process by which it is possible to produce transparent PP films in a thickness of 20 to 200  mu m which are monoaxially or biaxially oriented and the strength of which is at least 50% greater than in the case of unoriented films. The object is achieved by providing a process and an apparatus for producing biaxially oriented tubular films, preferably from polypropylene, with improved strength and transparency which is characterised in that the longitudinal orientation takes place for the most part in the melting range and the transverse orientation takes place for the most part in the crystallisation range and the longitudinal orientation is achieved by an increasing speed of the film bubble and the transverse orientation is achieved by inflating the film bubble.
Patent DE-4308986-A1 (DE)
Title: Protective circuit breaker
Inventor: MEYER HERBERT DR

Title: Gas-tight sealed alkaline accumulator
Inventor: HOGE DETLEV DR
IPC: H01M8/0271
Filed: 1993-08-13
Abstract: A gas-tight alkaline accumulator, preferably of the NiH type, is constructed, in accordance with the manufacturing process in the case of H2/O2 fuel cells, from an electrode stack which is enclosed by a cast resin, from which stack - in contrast to the operating principle of the fuel cell - the charge gases accumulating at the electrodes (6, neg.) and (10, pos.) are discharged separately as a result of the intermediate gas-impermeable separator (9) and are electrochemically converted at gas-specific consumable electrodes. Of these consumable electrodes, the O2 consumable electrode (3) is electrically short-circuited to the negative electrode and the H2 consumable electrode (14) is electrically short-circuited to the positive electrode. The gas is guided via longitudinal channels comprising mutually aligned bores (20) at the four corners of each part, such that diagonally opposite channels guide either only oxygen (thick arrows) or only hydrogen (thin arrows), the penetrated electrodes having, for protecting their active material from inadmissible gas inlet, corners of cast resin (19) with rings or sleeves (18, 21) embedded therein as gas passages. <IMAGE>

Filed: 1993-09-30
Abstract: The training range comprises a flat belt (3) which is directionally stable in the vertical direction and runs over a pulley (2) which is mounted at both ends of a frame (1). The speed of the belt can be varied and the rotation direction can be changed. A holder (16) is attached to the outside of the belt (3). A practice target (5) with a picture (24) of a clay pigeon, which is surrounded by a circle (25), is mounted removably in said holder (16) such that the angle of the practice target (5) with respect to the holder (16) can be varied. The height of the frame (1) above the ground and the inclination angle can be varied. Using a training range according to the invention makes possible realistic training using the techniques for clay-pigeon shooting as an alternative to actual clay-pigeon shooting on clay-pigeon ranges. The firing practices can be carried out using weapons with a relatively small bore (calibre), for example air guns. In consequence, noise emission and other environmental stresses are considerably reduced. <IMAGE>
