Title: Device for forcing detonating caps out of empty cartridge cases
Inventor: JAKOBS FRIEDOLIN DIPL ING
IPC: F42B33/04
Filed: 1986-08-26
Abstract: A known device for forcing detonating caps out of empty cartridge cases consists of a hollow cylinder having a pressure stamp which can be displaced longitudinally in the hollow cylinder and one of whose ends projects out of the hollow cylinder, of a cartridge-case holder which is directed in the same direction as the hollow cylinder, and of an opposing bearing for the base of a cartridge case which is arranged in the cartridge-case holder. A disadvantage of the known device having a mechanical ejector is that this device cannot be used for different cartridge cases. The novel device, in contrast, is intended to be usable for cartridge cases of different type and size, without any risk of damaging the cartridge case. For this purpose, the pressure stamp has a tightly sealed piston, the cartridge-case holder is arranged removably on the end of the hollow cylinder facing away from the projecting end of the pressure stamp and/or is constructed elastically, a seal is provided between the hollow-cylinder output and the cartridge-case holder, and the space, located between the piston and the cartridge-case holder, in the hollow cylinder is constructed as a pressure chamber for a hydraulic medium. By virtue of its construction, the device is suitable for forcing detonating caps out of empty cartridge cases of different calibre.

Title: Intercept computer
Inventor: HOLDORF ROLAND
IPC: G06G1/08
Filed: 1987-02-09
Abstract: The Holdorf intercept computer is intended to simplify the work of aircraft pilots in aviation. If it is intended to fly an aircraft from the instantaneous position onto a specific required track, at the moment, the aircraft pilot must calculate the track to be steered either in writing or in his head, without adequate aids. Errors can occur in this process which result in the aircraft pilot steering an incorrect track. The Holdorf intercept computer can be operated by one hand, and the aircraft pilot can read off his intercept heading to be steered, with only one adjustment. An attached drawing shows the computer in its size for use (actual size). <IMAGE>

Patent DE-3709152-A1 (DE)
Title: Container
Inventor: KIEFER JOSEF
IPC: B65D90/02
Filed: 1987-03-20
Abstract: The support elements provided in known containers reinforce the tubes due to the fact that they are attached to the container wall. This requires many attachment points, which are complex to manufacture, on the container wall and makes assembly difficult. In order to increase the resistance of the tubes to bending out and to secure them against inherent movements, a closed ring, running at a distance from the container wall, is used as the support element and, with the tubes running essentially parallel to the longitudinal axis of the container, forms a cage-like, rigid structure (G) which is supported on the lid (3) or bottom termination and/or on the container wall (2). The necessary reinforcement and support of the tubes inside the cage-like structure is achieved in this manner. Owing to the constructionally simple reinforcement and support of the tubes, the container (1, 1') is suitable as a hopper, tank or mixing hopper in which the tubes can be loaded by friction in the longitudinal direction and by transverse forces. <IMAGE>

Abstract: A control system for switching on and off an oil- or gas-fired heating boiler and a circulating pump of a heating installation has a blocking circuit which measures the boiler temperature. To avoid condensate formation, the pump (2) remains switched off until a minimum boiler temperature is reached. Switching off the boiler (1) before the minimum boiler temperature is reached is avoided by the fact that the switching-on signal for the boiler (1) is supplied to the boiler (1) via a holding circuit (6, R1). The holding circuit (6, R1) is restored only after the minimum boiler temperature is reached.   <IMAGE>
Patent DE-3739829-A1 (DE)
Inventor: HEINECKE RUDOLF AUGUST HERBERT
IPC: B41N1/00
Filed: 1987-11-24
Abstract: A method of manufacturing a gravure print roller includes providing a hard surface layer on a cylindrical body, and forming an array of recesses in the hard layer. As described a steel roll bears an A1 coating to which hard silica is applied. The silica is patterned with photoresist and etched to leave recesses which pass into the underlying A1. Both the remaining photoresist and silica are removed to leave indentations in the A1, after which a nitride layer is applied. Anisotropic etching of the nitride leaves only the vertical walls of the pits coated with nitride after which the A1 surface is anodised. The pits are then selectively filled to form the image. This may be by filling all pits and subsequently removing material from selected pits. As shown Fig 5, the finished steel cylinder (11) bears residual A1 (12) covered by A1 oxide (18) in which pits (16) are formed. The walls of the pits are coated with nitride (17a), and selected pits are filled with plastics material (19). <IMAGE>
