IPC: B32B19/00
Filed: 1991-03-29
Abstract: The surface of thermal insulation plates (1), to be covered with mineral fibre insulation and especially basalt fibres, is given an air permeable wetting with a hydrophilic solution at least in the areas in contact with a bonding agent. This gives hydrophilic surface zones (2a) where the surface has been treated. The thickness of the treated surface zone (2a) of the plates (1) is not greater than 2 mm. The butting surface areas (2") of the plates are pref. wetted with the soln. and the treated side (2) of the plate is coloured for identification. The soln. pref. contains a non-flammable bonding agent using an alkali-waterglass soln. with a mass ratio of SiO2:alkali oxide of 1.8-2.5 together with up to 100 pts./wt. of calcium carbonate. ADVANTAGE - The surface treatment allows the plates to be bonded to carriers by watery adhesives and give a good locking action without the use of dowels and the like.

Title: Injection mould for prodn. of compact discs or similar - besides usual fixed and moving tools it has another mould tool which can be moved e.g. by hand transversely on guides when mould is open
Inventor: HEHL KARL
IPC: B29C45/56
Filed: 1992-04-25
Abstract: An injection mould for the prodn. of (partic.) thin flat plastic mouldings has at least two tools moving together in their closure direction and at least one other tool which can move on guides in the mould, whereby the closed mould forms the cavity concerned. The last-mentioned tool, which can also be removed from the mould, can be moved at right angles to the closure direction between the two main mould tools when they are at least slightly open and can be taken to a position set by the guides where it can be attached to one of the main tools. The side view shows the two main mould tools (24,25) forming the cavity, between the fixed (10) and moving (11) plates. These tools (24,25) thus move together in the direction (s-s). A further plate (22) can move on guides and it forms the mould cavity with the other tools (24,25). In particular it (22) can be taken out from one side i.e. at right angles to the direction (s-s), when the tools (24,25) have been at least partly opened. The end position of this member (220 is limited by its guides (23); the plate itself (22) is U-shaped and therefore can fit into a matching shape on the guides (23). It has a small lug so that it can be removed by hand. It (22) can hold a plate or embossed film on its face for moulding CDs. ADVANTAGE - The mould can produce large vols. of mouldings per unit time but without any reduction in their quality. It is suitable for making e.g. thin flat compact discs.

Patent DE-4218369-A1 (DE)
Inventor: KIRIAZIS LEONIDAS DR
IPC: B32B15/08
Filed: 1992-06-04
Abstract: A process is disclosed for producing a metal-plastic film composite material by sheet die extrusion of a statistical polypropylene copolymer into a plastic film. After leaving the sheet die, the polypropylene is cooled by means of cooling cylinders and the plastic film thus obtained is laminated onto at least one of the main surfaces of a metal sheet. The process is characterized in that the polypropylene copolymer is directly cooled after leaving the sheet die of the extruder down to temperatures between 0  DEG C and 15  DEG C. Once the plastic film has been laminated onto the metal sheet by means of a solvent-containing or aqueous adhesive, the metal-plastic film composite material thus obtained is cooled down to temperatures from 0  DEG C to 25  DEG C, when the film is laminated onto the metal sheet at temperatures above the melting point of the polypropylene copolymer, or when the plastic film is laminated onto the metal sheet by means of a coextruded bonding agent the metal-plastic film composite material thus obtained is cooled down to temperatures from 0  DEG C to 25  DEG C. Also disclosed is a metal-plastic film composite material produced according to this process and its use for producing packaging containers.

Abstract: A shoulder-moulding bag is produced for the mfr. of tyres. The process uses a first bag made of cords plus rubber and wire cords plus rubber; this is inserted into part of a drum where it will for the shoulder bag; an outer drum is next added and the material of the first bag is bonded to a part of the outer drum. A second bag, with a rubber layer on each side of a fabric core, is inserted into the first drum so as to bond on to the base of a pre-polished valve arm; an end of the second bag is placed on a base surface of the outer drum and a valve connector is assembled with the threaded part of a valve stem. An opposite end of the second bag is folded over to a set line and there fixed by a suitable tool; the second bag is moved so as to press against a particular part of the outer drum and it is there pressed; the material of the first bag is then attached also; the resultant half-finished bag is coated with adhesive and a nylon fabric is applied to it. A covering drum is next applied to the product, and compressed air and steam are fed in at the same time to cure the materials concerned. ADVANTAGE - The process is free from the present problems (e.g. cracks appearing at the most highly stressed areas), esp. the faults in the "C-area", which are liable to occur when the moulding bag is used repeatedly. Moreover the method produces tyres with better properties such as (partic.) service li

Title: Control circuit for vehicle electronic throttle setting - uses self-analysis by comparison of engine speed signals and vehicle speed signals
Inventor: FREYTAG ADOLF
IPC: F16H59/42
Filed: 1992-06-26
Abstract: The throttle is set by an electronically controlled system following the throttle control settings. The throttle servo provides actual signals with correction wrt reference signals using comparator circuits. A double check is provided by comparing the actual signals with signals derived from the engine/vehicle speed monitoring circuits. The processor control collects corresp. data for vehicle/engine speeds for different throttle settings and gear ratios. If the actual throttle signals differ from the control signals by more than a set level, after a programmed time delay, a failure situation is signalled. ADVANTAGE - No redundant monitoring system required, simple processor control.
