Patent DE-4114496-A1 (DE)
Title: Control system for sheet-metal deep drawing press - with the drawing velocity varied as a function of the sheet holder velocity
Inventor: FORSTER INGBERT DR
IPC: B21D24/14
Filed: 1991-05-03
Abstract: The control system is intended for a deep drawing press including a drawing tool (a male die 4, a female die 3). In such a tool the metal sheet (6) is clamped - by means of rods (7) and one or several hydraulic cylinders (9) - between the surrounding area of the die (3) and a sheet holder (5) carried along by the die (3). The cylinder pressure is regulated by an output signal (Ra) from a regulator (R) comparing the actual pressure variation (Pi) with the required pressure variation (Ps). The system is characterised by the fact that a drawing velocity (Zg) is derived from the velocity of the sheet holder (5) and that the pressure variation (Ps) is fed to both the regulator (R) and a computer (C). The latter combines the quantities (Zg) and (Ps), and issues the result as an influence signal (B) superimposing the signal (Ra). USE/ADVANTAGE - The invention can be used with deep drawing presses. In comparison with the existing methods, it enables the quality of deep-drawn components to be further improved by allowing variations of additional process parameters to be taken into account during the drawing operation.

Title: Electrohydraulic control system allowing small incremental steps - uses control valves comprising main valves and control valves in series
Inventor: SEBASTIAN LOTHAR DIPL ING
IPC: F15B9/12
Filed: 1991-11-23

A main valve (24) connects the composite valve to the supply tank while a main control valve (16) has inlet (17), flow restriction (18) and non-return valve (20) and is in series with a control valve (21) controlled by the cam positions. ADVANTAGE - Fine degree of control using limited amounts of fluid, including during positioning, retention and change of direction.

Title: Microwave aircraft landing procedure for poor visibility conditions - using EM beam provided by satellite and reflected from ground surface in direction of approaching aircraft
Inventor: BRAUN HANS MARTIN DR
IPC: G01S5/14
Filed: 1992-04-01
Abstract: The landing system uses a satellite for providing an e.m. beam illuminating the ground area in the vicinity of the aircraft landing path to provide a signal which is reflected back in the direction of the approaching aircraft. The reflection intensity of the signal is dependent on the reflecting material, the aircraft landing path having a different reflection characteristic from the surrounding ground area to allow it to be displayed on a radar screen within the aircraft. Pref. the aircraft also receives the satellite signal directly for use as a reference signal for correlating the reflected signal. USE - For landing aircraft in poor visibility at airport which does not have automatic landing system.

Patent DE-4225264-A1 (DE)
Inventor: KRAMER FRIEDHELM
IPC: A41H37/00
Filed: 1992-07-31
Abstract: The invention relates to a machine for fitting rivets, press-studs or the like with a base tool (5) acting as a support in riveting, a controlled-lifting upper tool (7) and a rivet holder (28) allocated thereto which is part of a finger protection device which monitors the working travel of the rivet holder (28) on a lifting rod (73) and, if the descent has not been completed, cuts off the drive to the fitting machine. To the lifting rod (73) moved by the upper tool ram (7) via a braking device is allocated an electric switching device consisting of two switches in parallel, one (80) of which stops the machine if the lifting rod is shifted and the other, a bridging switch, which is in the closed position only when the safety distance between the upper tool (7) and the base tool (5) is below a certain value, keeps the drive operative. For greater safety, the invention proposes that to the bridging switch controlled by the rotary movement of the upper tool drive is allocated a monitoring switch (65) which detects the locking of the operative position of a platen (46) allocated to the base tool (5) which can be pivoted out of this position.

Patent DE-4303777-A1 (DE)
Title: Mattress for comfortable lying and restful sleeping
IPC: A47C27/14
Filed: 1993-02-09
Abstract: In the case of a conventional mattress, the arms, lying under the body, take a considerable part of the body weight. Since the area of the arms which come into contact with the mattress is small, the pressure exerted on them is large. For this reason, comfortable lying in this position is made difficult. The object of this lying method is to enlarge the bearing surface of the body to reduce the pressure load. This mattress (1) comprises an upper part (2), in which channels (3) for insertion of the arms are provided on the left and right, and the lower part (4) which possesses wide gaps (5) enabling the movement of the arms on a horizontal plane. The simple original mattress makes possible comfortable lying in side positions and the prone position and is especially suitable for hospitals and nursing homes. The possibility of using it as an ordinary mattress by turning it over, as well as its exceptional freedom of movement, make it suitable for any bedroom. <IMAGE>

Title: Heating installation which additionally generates electrical energy
Inventor: PHILBERTH KARL DR
IPC: F02G1/04
Filed: 1993-03-19
Abstract: There exist installations which burn fuel and generate both electrical and thermal energy. In the emergency generating set, the electrical energy is generated only for one's own requirements; in the heating and power station, the thermal energy is transported to the surrounding area as long-distance heat. Transportation of long-distance heat is expensive and requires an independent pipeline system, the transportation of electrical energy on the other hand is simple and can use the existing network. Based on this, the invention sets itself the object of providing a heating installation which consumes the generated thermal energy for heating one's own house and feeds electrical energy which has not been consumed by oneself into the general network. The network is thus relieved in times of peak demand. The invention solves this object by virtue of the fact that a Stirling motor (hot-gas motor) (10) which receives its inflow heat via the burner (6) and delivers its outflow heat to the heating circuit (1, 2, 3, 4, 5) is coupled to an electrical machine (12) which in the operating state works as an asynchronous generator and in the starting state works as an asynchronous motor. The concept of the invention can be applied in principle to any fuel-fired domestic heating installation. <IMAGE>

Title: Stereoscopic arrangement and method for spatial observation of microscopic objects
Inventor: SCHWERTNER DIETMAR DIPL ING
IPC: G02B26/04
Filed: 1993-04-08
Abstract: The invention relates to a stereoscopic arrangement and method for spatial observation of microscopic objects through a single-channel microscopic system, in particular through a single-objective optical microscope with a binocular tube (body). The object of the invention is to permit stereoscopic microscopy at high magnification at the limit of resolution (resolving limit) of the optical microscope and, at the same time, to avoid the disadvantages of indirect observation. This object is achieved by means of an arrangement in which an object translator, arranged in the object-side beam path of a single-objective optical microscope in the object plane, and a beam-path switch, arranged in the image-side beam path, are coupled in a phase-locked manner by an electronic control. According to the invention this arrangement generates and separates pairs of stereoscopic images (stereo pictures) simultaneously and at a sequence frequency above the flicker limit.

Patent DE-4314714-A1 (DE)
Inventor: SEITZ KARL
IPC: E04B1/348
Filed: 1993-05-04
Abstract: The invention discloses a free-standing carcass unit or system-built structural unit, as three-dimensional body for constructing single-storey or multiple-storey building structures from a multiplicity of such three-dimensional bodies, each three-dimensional body being made up to prefabricated compound elements which each form a two-hinged frame in the longitudinal direction and a three-hinged frame in the transverse direction. The three-hinged frame can be transferred into a two-hinged frame by positive or frictional locking. Advantageously, the two prefabricated compound elements are produced together from concrete in such a manner that, after their manufacture, they can be separated for transportation and/or for storage, can be connected once again on site for constructing the building structure, and can be separated once again for dismantling the building structure in order then, if appropriate, to be used in a corresponding manner for constructing another building structure. <IMAGE>
