Title: Reflecting display device (head-up display)
Inventor: BECKER WOLFGANG ING GRAD
IPC: G02B5/28
Filed: 1981-01-30
Abstract: The invention relates to a reflecting display device (head-up display) as is used in aircraft. This device uses an optical system containing a semireflecting mirror to reflect additional information, e.g. information represented on a cathode ray tube, into the field of view of the pilot. According to the invention, use is made as the superimposition mirror of a dichroitic mirror of a type such that the mirror reflects strongly in the frequency band of the light coming from the cathode ray tube but is effectively transparent for other light. As a result, the brightness of the reflected information is increased without substantially impairing the observation of the world outside by the pilot.

Title: Hydraulic press and its use in a method of manufacturing elements which are subjected to at least two different production operations
Inventor: FELDHAUS HANS
IPC: B21D35/00
Filed: 1981-03-28
Abstract: The invention relates to a hydraulic press with a hydraulic press piston guided in a press cylinder, a tool connected to it in a fixed position relative to the press piston, and at least one hydraulic damping piston producing a damping force in the opposite direction and guided in a damping cylinder, the press cylinder and the damping cylinder being allocated in a valve-controlled manner to a hydraulic line system, and the damping force of the damping piston being opposed to the force of the press piston only during the last part of the stroke of the press piston. The object of the invention is to simplify the construction of a hydraulic press of this type, to reduce its operating energy and to prevent unexpected blows of the press piston on the damping piston. This object is achieved according to the invention in that the press piston (4) and the damping piston (7, 8) are connected to one another in a fixed position relative to one another, and the working side (12) of the press piston (4), via a first line (13), and its piston-rod side (14) and the working side of the damping piston (7, 8), via a second line (15) separate from the first line (13), are allocated to a common four-way main valve (18) via a first (16) and a second (17) valve-controlled non-return valve, a pressure-relief valve (32) being arranged in the second line (15) upstream of the second non-return valve (17). Such a press is used wherever the cutting shock of a tool is to be prevented or dampened. <IMAGE>

Title: Method and devices for utilising low temperature drops
Inventor: HESSE HORST DR ING
IPC: F01K25/06
Filed: 1981-03-28
Abstract: The method of Hirn, according to which a gas can be heated above the temperature of the heat source in a constant space not by simultaneous heating, but by heating in layers successively, has been made more effective by a lapsed national patent by additionally evaporating fluid in the gas space. The following means serve further to increase the effect:   1) expulsion of a gas, other than the gas already present in the space, from fluid,   2) evaporation of a mixture of different fluids, 3) expulsion and evaporation after heating of the gas which always remains in the circuit,   4) heat and cold extraction at constant pressure.   The methods 1) to 3) can be reversed. The pressure increase arising during heating, expulsion and evaporation can be used for yielding mechanical work by which the cooling effect is increased. It can also serve to impart high speed to the gas mixture which is thus cooled. It is thus capable of absorbing heat from the heat source or from the environment (cooling). If the speed is then reduced, speed energy is converted back into internal and pressure energy, the sum of which is greater than before the process by the heat absorbed from outside. The temperature of the mixture has thus increased. The processes described under 1) to 4) are intended to take place in bellows, between which the gas mixture is moved by heat exchangers with the aid of a linkage which engages around the bellows. <IMAGE>

Title: Inductive position detector
Inventor: STRAUB GERHARD
IPC: G01D5/20
Filed: 1981-03-31
Abstract: In an inductive position detector, in which the change in inductive impedance when a soft iron core is moved in the area of a coil excited by alternating current is used as a position criterion for an actuator connected to the soft iron core (WK), this soft iron core moves within a metal tube (DR) which is enclosed by the winding (W1, W2) and which should have as high as possible a magnetic resistance in order to prevent a shielding of the field lines and which should have a high electrical resistance in order to keep the eddy current damping as low as possible. In practice, a non-ferromagnetic pressure tube of stainless steel has been found to be suitable. The inductive position detector can operate with one or more independent circuits, as a result of which one or more positions along a linear or also a curved path of movement can be identified.

Patent DE-3215224-A1 (DE)
Title: Device for reducing the energy contained in a liquid or gaseous medium
IPC: F16K47/08
Filed: 1982-04-23
Abstract: Devices of this type can be designed as a control or restriction valve or even as a silencer. In general they have a hollow-cylindrical restriction body with guide plates mounted on it for deflecting the medium from an axial direction to a radial direction. In order to reduce the design cost and to provide a more robust and also universally usable embodiment for a device of this type, the invention proposes that the guide plates have annular grooves which are concentric to one another, are open towards one plate side and are defined by circular, likewise concentric, partition walls, that the partition walls be provided with through-holes distributed over the periphery, which through-holes connect adjacent annular grooves, and that the open annular grooves be covered by an adjacent guide plate. On account of this design, the energy contained in the flowing medium can be reduced especially effectively. Furthermore, the design permits any assembly of valves and silencers according to the modular construction principle.

In order to prevent double imprints on the adhesive label the device includes retaining means (46, 60) which hold the printer carrier (20) in the operative position with a retaining force that is less strong than the resetting force.
Patent DE-3218344-A1 (DE)
Title: Accumulator-loading valve
Inventor: HEIBEL HELMUT
IPC: B62D5/07
Filed: 1982-05-14
Abstract: The accumulator-loading valve serves to supply a fluid accumulator (24) as a matter of priority before at least one other consumer (26), in particular in hydraulic devices on vehicles. The valve has a housing (10) with a cylinder bore which extends between a pump connection (12), an accumulator connection (14) and a consumer connection (16) for the consumer or further consumers (26) and contains a control chamber (36) into which the accumulator pressure can be transferred. The housing (10) contains a pilot-control piston (76) on which the accumulator pressure acts on the one side and an initial load acts on the other side and which leaves open a connection between the control chamber (36) and a return connection (18) for a return line (28) only below a lower operating pressure in the fluid accumulator (24). Guided in the cylinder bore is a main control piston (60) which, with an annular face (A36-A34) formed on it, defines the control chamber (36) and is preloaded by a spring (70) in such a way that, when the operating pressure falls below the lower limit, it leaves free a connection between pump connection (12) and accumulator connection (14) and separates the consumer connection (16) from the pump connection (12). On the other hand, if an upper operating pressure is exceeded, the main control piston (60) clears a connection between pump connection (12) and consumer connection (16) and separates the accumulator connection (14) from the pump connection (12). The fluid accumulator (24) is thereby protected from overloading. <IMAGE>
