Title: Extruding screw for the stiff-plastic pressing of ceramic masses, in particular oxide-ceramic and special-ceramic masses
Inventor: DIETRICH RUDOLF
IPC: B30B11/24
Filed: 1988-09-09
Abstract: The aim of the invention is to achieve an optimum adaptability of the extruding screw to the degree to which different stiff-plastic ceramic masses can be pressed. The aim of the invention is achieved by the extruding screw being composed of a conveying screw and a variable, conical thrusting screw, differing from the conveying screw in pitch and number of flights. The connection between conveying screw and thrusting screw takes place both positively and non-positively. Counter-knives arranged radially displaceable on a level with this connection ensure influencing of the mass flow in the transitional region between conveying screw and thrusting screw. <IMAGE>

Title: Guide for bandsaws
Inventor: HEGMANN ROLF
IPC: B23D55/08
Filed: 1988-09-16
Abstract: The present invention relates to a guide for bandsaws, in particular for high-speed bandsaws such as, for example, diamond saws for stone-working. It consists of surfaces which are opposite one another in a metal block and together form a slot with a slightly larger width than the saw-band thickness. Nozzles which can be acted upon by a pressure medium are arranged in the slot. Here, the depth of the slot is less than the width of the saw band so that the working zone, e.g. the area set with diamond chips, projects to the outside and is cleaned or cooled by additional nozzles. The rear guidance is obtained by conventional, rotating back rollers.

Title: Emergency drive system for the aiming optics of an armoured vehicle
Inventor: WEINFURTH UDO DIPL ING
IPC: F41G3/22
Filed: 1988-10-29
Abstract: The invention proposes an emergency drive system for the aiming optics of an armoured vehicle, by means of which system highly accurate elevation-dependent slaving of the aiming optics is made possible in the event of failure of an otherwise normal electrical drive system. In comparison with conventional emergency drive systems, using which the desired high accuracy for elevation-dependent slaving of the target optics cannot be achieved despite considerable adjustment complexity, the emergency drive system according to the invention offers the advantage that it manages without any complex adjustment and, furthermore, can be accommodated in tank turrets in a more space-saving manner than previously known emergency drive systems. The emergency drive system (10) according to the invention is designed as a type of belt drive and essentially comprises a drive shaft (24), which is hinged on a trunnion (22) of a panel (20), and a slave shaft (18), which is hinged on the aiming optics (16), both shafts (24, 18) being connected by means of at least one steel belt (28) in order to transmit the elevation-dependent rotary movement of the drive shaft (24) to the aiming optics (16). <IMAGE>

Title: Automatic clutch operation with return device
Inventor: TELLERT RUDY
IPC: F16D48/06
Filed: 1989-03-18
Abstract: The invention relates to a device for the automatic operation of a friction clutch in connection with a manually shifted multi-speed transmission. In gearshift sequences from a higher to a lower gear, an engaging sequence for the friction clutch is selected from the engine and transmission input speeds, which provides for a certain engine speed increase, which is essentially equal over the entire engagement sequence, but is fixed at different levels in the event of differing speed ratios. This results in a high rate of engine speed adjustment being set in the event of large speed differences. In this way a high braking torque is also exerted on the vehicle, when deliberately changing down at high vehicle speeds.

Patent DE-4006863-A1 (DE)
Inventor: SPRINGER JOHANN DR RER NAT
IPC: G02B6/12
Filed: 1990-03-05
Abstract: In a process for the production of an optical waveguide (optical fibre) component in which a glass substrate is fitted with optical waveguides made from an optical polymer, the surface of the glass substrate is coated with a protective layer and the protective layer is subjected to a photolithographic process in order to produce a line structure at the relevant points at which the optical waveguides are to be arranged. In the line gaps thereby formed in the protective layer, hydrofluoric acid is introduced on to the glass substrate in order to etch out a capillary-like channel, and the resultant channel is filled with the optical polymer. This allows optical waveguides whose cross-section geometry is approximately the same as that of the transmission glass fibres used for light wave propagation to be introduced into waveguide components.
