Patent DE-4311020-A1 (DE)
Title: Water-heating installation
Inventor: SCHULZKE STEFAN
IPC: F24D10/00
Filed: 1993-03-31
Abstract: In a water-heating installation with a heat exchanger (8) connected to a distant-heating network and at least one hot-water storage tank (13-15), the heat exchanger (8) and the hot-water storage tanks (13-15) are arranged in branches (3, 4) of a ring main, by means of which the storage tanks (13-15) are filled with hot water by a basic-load charging pump (7). In order to make available to the consumers sufficiently large quantities of hot water even in cases of peak load, the installation is additionally equipped with a peak-load charging pump (19) which is controlled by a hot-water-side temperature sensor (20) and, in the event of complete discharge of the hot water from the storage tanks (13-14), increases the volume flow through the heat exchanger (8). <IMAGE>

Title: Method for stabilization of a firing post (weapon system)
Inventor: HABERSTOCK FERDINAND DR ING
IPC: F41G5/24
Filed: 1993-06-01
Abstract: A method for stabilization of a firing post, which is preferably arranged on a vehicle, using current control loops for driving the electric motors of an elevation and/or azimuth drive, using speed control loops which are equipped, in particular, with rate gyros as sensors for determining the inertial weapon speed and are superimposed on the current control loops, and, preferably, using a slaving control loop, which is superimposed on the speed control loops, for slaving the turret in azimuth and the weapon in elevation to a controlling aiming device. The requirement profile placed on a stabilization system in terms of the stabilization and slaving quality is satisfied in that the respective speed control loop is extended by a secondary torque control loop and a further rotation speed control loop, which is secondary to the torque control loop, and in that the sensor which is associated with the torque control loop is designed as a force measuring device which detects the elastic deformations, which are caused by disturbance and/or aiming movements, of the respective drive mechanics and/or their retaining devices. <IMAGE>

Title: Process and apparatus for producing webs from thermoplastic mixtures, resin mixtures or the like by means of belt presses
Inventor: ROSCHER FRIEDER
IPC: B30B15/34
Filed: 1993-06-09
Abstract: Process for continuously producing webs from thermoplastic mixtures or resin mixtures or materials bonding with one another, which are compacted on belt presses or double-belt presses and, during pressing, tend to adhere to the belts due to adhesive action. Following the compressing operation, the adhesive bonding of the material web to the pressing belt or the pressing belts is interrupted by a shock-like cooling of the pressing belt or the pressing belts on one side. This is followed by separating the material web from the pressing belt or the pressing belts.

Patent DE-4329864-A1 (DE)
Title: Optical-fibre branching arrangement
Inventor: KARSTENSEN HOLGER DR
IPC: G02B6/125
Filed: 1993-09-03
Abstract: An optical-fibre branching arrangement, comprising a planar optical waveguide, a slit arranged in this waveguide for coupling out an optical power component from this one waveguide and a branching-off planar waveguide for guiding away the coupled-out power component, is intended to have, compared to a known such arrangement with uniform power distribution and very great slit length, a considerably shorter slit length and make possible a uniform power distribution and a non-uniform power distribution. For this purpose, the branching-off waveguide (2) branches off at an angle relative to the longitudinal axis (10) of the one waveguide (1), which angle is between 40 DEG  and 90 DEG , preferably close to 90 DEG , and the slit (11) runs perpendicular to the angle bisector (113) of this angle. The slit can run in a straight line or bent in order to compensate for beam divergence of the optical power carried in the waveguide. It is possible, without difficulties, to produce arrays from such arrangements. Use in optical communication systems. <IMAGE>

Title: Rotatably mounted roll
Inventor: JENKE DIETMAR
IPC: B29C43/24
Filed: 1994-05-27
Abstract: A description is given of a rotatably mounted roll (1) which, preferably with a second roll, forms a roll gap through which a web of material can be passed. The stress in the roll gap can be equalised by means of an adjustable convexity. For this purpose, the interior of the roll (1), which is designed as a cavity (13), is filled with an incompressible fluid and put under a pressure which is so high that it makes the roll shell (10/12) bulge. This can be greatly assisted and influenced by specific variation of the wall thickness of the roll shell (10/12). <IMAGE>
