Title: Winding bobbin clamps - have studs on ring section between spindle and mantle with low axial forces
Inventor: BUSCH HANS-JOACHIM
IPC: B65H54/54
Filed: 1980-10-16
Abstract: The radial clamps are clamping studs passing through the openings in the mantle surrounding the bobbin clamping spindle on a winding unit. The clamps pass straight through the openings, with radial movement, and carry radially movable clamping ends. The inner ends of the clamping studs are supported by axially rising, wedge shaped clamping sections, held in a sliding support on the clamping spindle. The design gives a high bobbin clamping force with minimal axial forces, using a ring clamping component which fills the space between the spindle and mantle, giving axially driven movement forwards and back. The design also reduces wear on high speed working.

Patent DE-3048802-A1 (DE)
Inventor: HINGER KLAUS-JUERGEN DR ING
IPC: B65G19/14
Filed: 1980-12-23
Abstract: A process for the hydrolysis of cellulose from vegetable raw materials to glucose, particularly using wood as the raw material, comprises conveying the raw material through a hydrolysis zone in finely comminuted form, the raw material being impregnated with dilute acid and at a sufficiently high hydrolysis temperature. The raw material impregnated with dilute acid is supplied in portions and continuously through the hydrolysis zone where it is heated to a hydrolysis temperature of above 250 DEG  C. by means of high pressure steam. This takes place in an extremely short time accompanied by a sudden pressure rise. Apparatus for performing this process comprises a tubular reactor having at least one straight pipe through which can be conveyed an endless piston chain. The pistons of this chain form a leakage gap opposite the inner wall of the pipe and, in each case, two adjacent pistons define a piston chamber. A high pressure steam line is arranged to issue approximately into the center of the pipe.

Patent DE-3109039-A1 (DE)
Title: Battery voltage monitoring device for cameras
Inventor: KAWABATA TAKASHI
IPC: H02M3/28
Filed: 1981-03-10
Abstract: A battery voltage monitoring device for cameras is specified which has a voltage-increasing circuit whose output voltage is fed to the loads as electric power. When in the case of such a camera the battery voltage is monitored via the output voltage of the voltage-increasing circuit, it is impossible to undertake any more precise monitoring process. The monitoring device is therefore used to monitor the voltage at the input of the voltage-increasing circuit in a different way. Since a further difficulty consists in that a specific time interval passes at the voltage-increasing circuit between start up and stabilization of the operating process, and that the voltage value detected during this time interval does not yield a precise representation, monitoring of the input voltage begins in the monitoring device after expiry of a predetermined time interval from start up of the voltage-increasing circuit, after which the operation of the voltage-increasing circuit has become stable; it is therefore always possible to achieve a precise and reliable battery-monitoring process.

Title: Method for releasing an igniter safety device and safety device with a release device for carrying out the method
Inventor: WEIDNER PETER ING GRAD
IPC: F42C15/30
Filed: 1981-07-03
Abstract: In a method for releasing an igniter safety device (19) or in a safety device (19) with a release device (20) for carrying out such a method, the time trend of the gas pressure (31) in the powder chamber (53) of a weapon barrel (6) or in the combustion chamber of a projectile, for example equipped with an afterburner, will be utilised as an environmental criterion and actuating force, for example for the displacement of a release bolt (28), with the barrel safety and, if appropriate, also an attachment barrel safety being guaranteed, without brief gas-pressure peaks or longer-lasting, but comparatively low gas pressure (31) already leading to this release function, at the same time in conformity with the requirements for safety against the penetration of hot powder vapours onto the explosive (5), with the igniter (3) still safe. For this, there is a thrust-piston system (27) integrating the gas pressure (31) and having two cylinders (29, 30), in which pistons (32, 33) are displaced counter to the restoring force of springs (39, 41) on the one hand by being subjected to gas pressure (31) and on the other hand by a flow medium (40) passing through a fluid throttle (34) in dependence on the gas pressure, the fluid throttle (34), opened in dependence on the piston position, in a partition wall (35) between the two cylinders (29, 30) serving at the same time, before and after the piston displacement, as a safeguard against powder-vapour penetration. <IMAGE>

Title: Method for the automatic introduction into an injection die-casting die of cylindrical rod-like objects to be embedded, and device for carrying out the method
Inventor: WEBER KURT ING GRAD
IPC: B29C45/14
Filed: 1981-09-05
Abstract: The invention relates to a method and a device for the automatic introduction into an injection die-casting die of cylindrical rod-like objects to be embedded, in which the rod-like objects are placed individually into respective die cavities. It is envisaged that the rod-shaped object to be introduced should be inserted individually between the associated die cavity and the associated ejector, in coaxial arrangement with respect to the already embedded rod-shaped object situated in the die cavity and with respect to the ejector, and that the ejector should then be made to execute a feed motion along a path which coincides with the axes of the two rod-like objects. In the course of this feed motion, the finished die-cast workpiece is ejected by means of the rod-like object to be inserted into the die cavity and the latter is introduced into the die cavity.   <IMAGE>

Title: Production of an injection mould for small production runs of up to 5,000 items
Inventor: SCHLENK REINER
IPC: B29C33/56
Filed: 1981-09-22
Abstract: The invention relates to the production process for producing inexpensive moulds from non-ferrous metals which can be produced rapidly and altered rapidly. Hitherto, a multiplicity of processes have been available for injection mould production. The extension of the process range by this process is intended to expand the application range of the plastics processing moulds which shape by a non-cutting method in small and medium-sized production runs in series production. This is achieved by the fact that the moulds can be produced rapidly and also by their low investment costs, mould costs and labour costs and their rapid alterability and adaptability, compromises having to be made in the lifetime and cycle time in the injection moulding process. It is known to produce moulds from non-ferrous metals for plastics processing by various processes, however a simple, tried and tested process, which can be rapidly used in practice, is lacking for potential users. The invention therefore demonstrates a process which is tried and tested in practice for the production of prototype moulds within 8-16 working hours.
