Patent DE-3828317-A1 (DE)
Title: Falling-film evaporator
Inventor: HESS ERWIN DR ING
IPC: H01R13/68
Filed: 1988-08-20
Abstract: The demands on falling-film evaporators are on the one hand the most effective possible separation of condensate and vapours and on the other hand the most compact construction possible. The object underlying the invention is to improve the separation between concentrated juice and vapours by simple means and simultaneously to achieve the most compact construction possible of the lower region of the falling-film evaporator. This object is achieved by the vapour take-off proceeding via an annular space (2) which is arranged in the vapour chamber (1) and has baffle strips (7), in which annular space the condensate collecting line (18) also runs. Falling-film evaporators of this type are suitable for use in all areas of conventional falling-film evaporators, but in particular in the sugar industry. <IMAGE>

Title: Helicopter
Inventor: SCHNEIDER ADAM THOMAS
IPC: B64C27/12
Filed: 1988-09-07
Abstract: The rotor systems of helicopters are arranged above the cabin. It is thus impossible to provide ejector seats for rescuing pilots in the event of accidents, because the ejection path collides with the circle in which the rotor blades rotate. A cabin 1 is proposed having a circular outline, in conjunction with an annular rotor system 3 which is arranged on the outer casing 11 of the cabin 1. This rotor system 3 consists of a supporting ring 10 having a track rail 16 on which supporting elements 19 run around, to which the rotor blades 5 are fastened such that they can pivot. All the supporting elements 19 are set in motion by a toothed rim 31 which is rotated by the engine 2. The rotor system 3 can be tilted with respect to the cabin 1, by means of hydraulic cylinders 15. The invention is used especially in the case of helicopters whose lift is produced using only one rotor system. <IMAGE>

Inventor: JANNAKOS KONSTANTIN
IPC: B66C1/62
Filed: 1988-10-01
Abstract: A gripper for remotely-operated gripping in the transport of barrels or containers of radioactive or toxic materials, which have on their upper side or their lid an undercut mounting ring behind which horizontally movable carrier arms or coupling bolts of the gripper engage, the coupling bolts being mounted movably in the gripper housing. The gripper has on the upper side two gripping mushrooms 7, 8 of which one 7 is arranged approximately in the geometrical centre of the gripping body 4, 6 and the other 8 is arranged eccentrically thereto. One gripping mushroom 7 is mounted rigidly on the gripping body 6, the other 8 is designed to be axially movable, penetrating the latter. The movable and eccentric gripping mushroom 8 is articulated pivotably at its lower end via a pit (recess) 16 and the rear articulation points 18 on toggle links 14. The toggle links 14 have further forward articulation points 19, with which they are articulated, likewise pivotably, on the rear ends of the coupling bolts 10. The coupling bolts 10 are mounted axially movably in bearing blocks 9 in the carrier frame 5 of the gripper. <IMAGE>

Title: Process and apparatus for the leakproof wrapping of an article
Inventor: GEYER FRIEDRICH
IPC: B65B53/02
Filed: 1988-11-03
Abstract: A process and an apparatus (10) for the leakproof wrapping of an article with a packaging foil shrinking as a result of the action of heat are described, the article first being surrounded by the packaging foil, subsequently the gap between the article and the packaging foil being selectively evacuated, and thereafter, if appropriate, the packaing foil being welded in such a way that it encloses the article on all sides. The packaging foil is subsequently exposed from outside to a heat by which the packaging foil shrinks and is laid against the article. In order to avoid a water bath and therefore wet work or in order to avoid an IR-radiation source and the risk of damage to the packaging foil possible as a result of this, it is proposed to supply the heat to the packaging foil by means of at least one elastic flexible press body (14, 16) which is pressed against the article enclosed by the packaging foil, in such a way that the article is covered by the flexible press body (14, 16). At least one elastically flexible press body (14, 16) having heating is therefore used as a heat source. <IMAGE>

Patent DE-3907523-A1 (DE)
Inventor: TERLETZKI HARTMUD
IPC: H01L21/822
Filed: 1989-03-08
Abstract: The invention relates to an overvoltage protection circuit for MOS components consisting of a resistor (R), a field oxide transistor (FOX) and a thin oxide transistor (DOX). The breakdown of the parasitic dipole transistor inside the field oxide transistor is optimised so that the latter can with certainty leak off all the energy of an overvoltage pulse against the reference potential (VSS). The measures described reduce the thermal damage known as "spiking" which can cause the MOS component to break down.
Patent DE-3911553-A1 (DE)
Title: Method and device for the detection of knocking signals
Inventor: DORNER ROBERT DR ING
IPC: G01L23/22
Filed: 1989-04-08
Abstract: Time integrals have hitherto been used in the detection of knocking signals in order to decide on the possible knocking condition of an internal combustion engine. According to the invention, however, an analysis of the peak value is performed, which works faster with good accuracy. It has been shown that the peak values in knocking and non-knocking engine operation differ more from one another than time integrals over the effective values and that the essential energy content of the knocking noise is already contained in the first peak value.

This positional adjustment enables the impression (60) to be correctly positioned to receive the model individual teeth etc.  During the adjustment process the position of the impression can be observed from the rear end (99) of the impression. USE - Production of dental prostheses.
Patent DE-3914703-A1 (DE)
Inventor: STEINHARDT LOTHAR DIPL ING
IPC: E03F5/10
Filed: 1989-05-04
Abstract: The invention proposes a sewage regulator for outlets from liquid containers, in particular storm-water retention spaces, having a screen (3) which is guided so as to be vertically movable above the outlet opening (2) and is motionally connected to a float (14) via transmission elements (5, 8, 11, 13). The transmission elements comprise a two-arm lever (8) pivotably mounted about a fixed pin (7) and of variable lever-arm length, a first lever arm (8a) receiving a supporting rod (5) connected to the screen or the screen directly and a second lever arm (8b) possessing a guide element (10), and also a control element (11) with a control curve (11a), the control element being pivotably mounted about a fixed pin and being connected, so as to be fixed in terms of rotation, to a float rod (13) receiving the float (14). The guide element of the second lever arm is guided in the control curve of the control element in a tension- and pressure-transmitting manner. The sewage regulator according to the invention makes it possible, independently of the flow characteristic preset by the control curve, to influence the flow rate owing to the variable lever-arm lengths, and it is simultaneously ensured that the screen is driven in a defined manner via the control element in all operating positions. <IMAGE>
