Title: Stenter frame - has spring held chairs to prevent the cloth being drawn out of shape during a heat process
Inventor: NESET KARSTEN T
IPC: D21F1/00
Filed: 1992-11-10
Abstract: Stenter frame accepts a continuous run of fabric and esp. for a process involving heat on paper maker cloths. The frame has chairs connected by studs to a chain drive at each edge of the fabric. By means of springs at the sides of the studs, and a control system to register and adjust the tension on the cloth, the speed of the chain can vary from that of the cloth in process, until modulated. The stud (2) is pref. held in the links of an endless chain, which runs at each side of the frame. The chairs are provided with rollers with vertical axis to follow the side rails for variation in width across the frame. Each carriage has pin plates which are fixed with the pins (3) facing upwards, and at an angle to hook the cloth at the sides. The carriage has longitudinal slots and bars (5) to hold spiral springs (4) which press against the stud (2), so that the pins travel at the same speed as the cloth, until a sensor of tension adjusts the drive for the chain to coordinate. The tension sensor is contained in the chain drive motor, to determine the load factor, which may then be regulated. The spiral springs (4) have different characteristics between back and front, and chosen to suit the fabric. Pref. the chains run at a constant speed, and the variation is taken up by the springs. ADVANTAGE - The cloth is held under tension without being drawn out of shape. The speed of the cloth through the rollers determines the speed of the side chains.

Title: Apparatus for continuous and metered feed of viscous material
Inventor: HEINRICH WERNER
IPC: F04B23/02
Filed: 1993-11-25
Abstract: An apparatus for the continuous feed of a viscous material from an exchangeable pre-filled container (1) as used for impregnation during cable manufacture employs a single outlet system whereby pressure is applied to the surface of the material (2) by a hydraulically operated (5) pressure plate (7). During normal operation the material (2) travels to the cable-filling head (3) via a non-return valve (12) intermediate reservoir (10) and metering pump (11). On emptying the container (1) the plate (7) is raised by reversing the hydraulic cylinder (5) and air pressure is applied to the piston (14) of the reservoir (11). The material flow is thereby maintained via the branch (15), closed valve (12) and pump (11) during substitution of a full container.

Title: Ignition key arrangement
Inventor: BOENIG VOLKER
IPC: B60R25/021
Filed: 1994-01-29
Abstract: The invention relates to an ignition key arrangement for a motor vehicle which is electromotively driven at least at certain times and has a handbrake or a parking brake, e.g. for an electric vehicle or a hybrid vehicle which, inter alia, also has an electric motor. According to the invention, this ignition key arrangement has a locking device by means of which the ignition key is prevented from being pulled out of the ignition lock as long as the handbrake or parking brake of the motor vehicle is not effectively put on. As a result, without significant outlay it is ensured in a simple and advantageous way that on the one hand the driver of the electrically driven vehicle can switch off the electric system of the vehicle in an emergency situation by activating, i.e. turning back, the ignition key without this leading to the ignition key being inadvertently pulled out and thus to inadvertent blocking of the motor vehicle steering, and it is also ensured that the driver can only leave the vehicle and lock it with the ignition key if he has previously put on the handbrake or parking brake as required by statute.

Abstract: A piston compressor is described which has pistons which are arranged in bores of a cylinder block and are moved back and forth by a drive mechanism in interaction with a drive shaft. A valve accommodation chamber is formed in the cylinder block around the drive shaft, in order to accommodate a turning valve which corotates with the drive shaft. The turning valve has an intake duct formed therein, to duct gases from a gas intake chamber to a compression chamber formed in each bore. A multiplicity of connection ducts is formed in the cylinder block, assigned to the compression chambers, to provide a gas connection between the compression chambers and the intake duct of the valve. A bypass duct is formed on the turning valve and permits a connection duct assigned to one of the compression chambers, which is in the final stage of a compression stroke, to communicate with a different connection duct which is assigned to a different compression chamber which is in the initial stage of the compression stroke. The compressor further comprises a device which is provided on an external surface of each piston, for collecting gas which leaks in the axial direction along the outer surface of the piston. The gas collection device ducts the gas which it has collected in the final stage of the compression stroke, to the connection duct which ... its associated ... Original abstract incomplete.
