Title: Regulating plasticisation of viscous materials - by controlling parameters affecting material temp. e.g. screw torque over different sections of screw stroke until uniform
Inventor: BRUNNER DIETMAR
IPC: B29C48/92
Filed: 1992-03-28
Abstract: The plasticiation process of viscous substances, in intermittently operating equipment with a moving screw plunger and a multi-zone screw, is controlled particularly by altering the parameters which affect the temp. of the material, namely the barrel temp., screw speed and back pressure. These changes are made in sections depending upon their duration and the position of the material in the equipment, and they are utilised to even out the temp. of the mass along its length. ADVANTAGE - The procedure is designed for injection moulding machines and relevant parts of the plasticator stroke can be cheaply and simply ascertained without any disturbing measurement or their instruments.. In particular it dispenses with direct references to the temp. of the material as a datum value for making alterations

Title: Infinitely variable speed gearbox for vehicle - has twin fluid pump formed by sun wheel driving planetary gears, with centrifugally controlled throttle valves
Inventor: BRUNSCHWEIGER SEBASTIAN
IPC: F16H3/72
Filed: 1993-01-20
Abstract: The gearbox uses fluid force. A twin fluid pump is made up from a sun wheel (1) and the two planetary wheels (3) of an epicyclic gearbox, the sun wheel being mounted on the driving shaft from the engine. The ring gear is coupled to the driven shaft (and therefore, the wheels of a car, for example). The sun wheel has centrifugal controllers (servomotors and electronics) which can open or close the throttle valves (4) in the fluid path in the housing of the planetary carrier. For engine idle, the valves are open. As the engine speed increases, the throttle openings are progressively closed and the planetary gears are forced to drive the sun gear around.

Abstract: A method for disposing of flat problem material, in particular stamped grids (4) which remain after the stamping-out of adhesive labels. The problem material is guided through a longitudinal cutter (6) and cut up into longitudinal strips. The longitudinal strips are guided through a tube (20) to a transverse cutter (24) and cut up to form granulated material. The granulated material is fed to a disposal point, in particular to a refuse-incineration plant. An apparatus for carrying out the method has pairs of cooperating knife discs (14) rotatable about an axis transverse to the conveying direction. Arranged in front of the said knife discs (14) are conveying rollers. The transverse cutter (24) has knives (28) which are attached to a drive shaft (16) arranged transversely to the conveying direction, air passage openings (36) for the conveying air being provided between the knives and the drive shaft and outside the knives. For the purpose of applying a liquid lubricant, in particular oil, use is made of a brush roller (12.5) which cooperates with a stripper (12.7) in such a manner that the bristles led through under the stripper and bent over throw the lubricant onto the side, coated with glue, of the problem material when they resile. <IMAGE>

Title: Metering cap for a container
Inventor: KNEER ROLAND
IPC: B65D47/22
Filed: 1993-07-17
Abstract: The metering cap comprises a cap part which can be mounted on the container mouth, preferably screwed onto the latter, and on which an actuating part is seated displaceably and is pretensioned into a starting position by a spring. The cap part and the actuating part are passed through by a rubber-elastic metering insert which is provided with annular closing cams at two positions which are spaced axially apart. The actuating part has an inner surface which interacts with the two cams in such a way that they can selectively be opened or squeezed together radially such that the metering insert is tightly sealed in the region of these cams. In the rest position, the cam adjacent to the outlet opening of the metering cap is squeezed firmly together while the other cam is open, such that the metering insert is filled up to the front cam in the inverted position of the container. When the actuating part is pushed back into a first operating position, the second cam is squeezed together, such that a precisely predetermined volume of the container contents is enclosed between the two cams. When the actuating part is pushed back further, the rear cap continues to remain closed and the front cam is opened so that the metering quantity escapes.
