Patent DE-3726971-A1 (DE)
Title: Method for producing planar epitaxial layers by means of selective metal-organic vapour phase epitaxy (MOVPE)
Inventor: SPEIER PETER DIPL PHYS
IPC: H01L21/306
Filed: 1987-08-13
Abstract: A method for producing planar semiconductor layers on a planar, patterned semiconductor base material by means of selective MOVPE at atmospheric pressure is proposed in which the boundary overgrowths (14) arising at the boundaries between areas masked with a dielectric layer and unmasked areas are avoided. Isotropic etching of the exposed base material results in overhangs consisting of the dielectric layer which prevent any deposition of material from the vapour phase and only permit mass transfer. With an etching depth of from 3 to 4  mu m and overhangs of approximately 4  mu m on an indium phosphide substrate, boundary overgrowths are completely avoided. <IMAGE>
Patent DE-3728541-A1 (DE)
Inventor: KICHERER ROBERT ING GRAD
IPC: B65D85/62
Filed: 1987-08-27
Abstract: For the stacking of electric hot-plates (2) for transport, storage and assembly purposes, the stacking device has pallet plates (10), which are to be arranged one above the other in stack layers and can be stacked directly inside one another for storage, in the form of deep-drawn plastic plate parts with flat trays (19) which are arranged in a grid, receive the lower part of an electric hot-plate (2) in a centred manner, projecting in each case over the open side with the cooking surface (4), and are supported in relation to the cooking surfaces of the adjacent stack layer via an anti-slip device (31), but otherwise without contact. By this means, a very large number of hot-plates (2) can be held securely in the same alignment on one bearing pallet, protected by a packaging cover, and can thus be stacked for good access during assembly. According to an assembly method which can be carried out fully automatically using programmable handling tools, the hot-plates (2) required in each case are set down aligned in an inverted position, then an installation plate is plugged on in the inverted position and secured with a tensioning part in relation to the hot-plates, after which the connection members (33) of the hot-plate (2) are connected, if appropriate by spot weld connections, to a connection piece for connection leads and the assembled installation plate thus formed is fed to a stack.

Patent DE-3742949-A1 (DE)
Title: Device for mooring ships by applying a portion of the ship's weight to the bank or a structure on the bank without running the ship aground in the process
Inventor: RABENBAUER MAX
IPC: B63B21/00
Filed: 1987-12-18
Abstract: The invention relates to a landing stage mainly for small ships, which is equipped in such a way that the ship is partly lifted out of the water by it during berthing. This results in a bearing and holding force of the landing stage on the bank. The landing stage is attached to the bow of the ship and is rotatably mounted perpendicularly to the longitudinal axis of the ship. During berthing, the landing ramp is swung down by suitable, for example hydraulic, devices and thus the ship is partly lifted out of the water at the bow. The ship thereby rests with the front side of the landing stage on the bank. The holding force thereby attainable, which essentially depends on the weight which can be applied and on the friction coefficient at the bearing point, is adequate to hold the ship sufficiently firmly on the bank for a short period, for example for passengers to disembark and embark.

The actuation of the telescopic cylinder (17) leads to a maximum telescopic stroke (31) at the side-tipping bucket (26). <IMAGE>
Patent DE-3804023-A1 (DE)
Title: Hydraulic-booster system
Inventor: ANGER HEINZ
IPC: F04C11/00
Filed: 1988-02-10
Abstract: This system enables the hydraulically transmitted force to be converted into complete and continuous rotations. It is suitable for multi-purpose drives, e.g. generators, vehicles, ships, cranes. The characterising feature here is that the piston-carrying cylinders, which each contain one drive piston of smaller cross-section and one output piston of larger cross-section, are arranged in such a way that they also rotate. The smaller drive piston is pressed in a rotating manner by the external drive (the rotary speed is selective), and the hydraulic oil transmits the force to the output unit on account of the larger cross-section of the output piston. The hydraulic pump is driven from the output side. It forces the oil via volume- and pressure-control valves through an oil ring guide with control spool or through the reamed shaft into the cylinders. The design of this system can be varied depending on the power requirement. The piston diameters to be selected accordingly: drive pistons of about 15 to 50 mm, output pistons of about 40 to 500 mm. The requisite external drive force is to be proportioned in accordance with the counter-force which acts on the drive pistons. The pump size is to be selected according to the variable volume per revolution and pressures of up to about 150 bar. This hydraulic booster brings about a considerable energy saving on account of the multiple transmission conditions between drive and output. <IMAGE>

Patent DE-3811670-A1 (DE)
Title: Method for the compensation of the change in the positioning force of an electromagnetic drive for a proportional valve caused by temperature-induced resistance changes
Inventor: LAUSCH HORST DIPL ING
IPC: G05D15/01
Filed: 1988-04-07
Abstract: The heating of the proportional magnet of a proportional valve which occurs in operation leads to an increase of the coil resistance and thereby to a reduction of the static valve amplification. The resistance change is compensated by determining from the temperature-induced change of the zero control voltage for the valve a correction factor by which the control amplification is multiplied in order to compensate the resistance change of the coil winding. The considerable cost of the compensation of the resistance change with the aid of current control necessary in the prior art is thereby eliminated.

Inventor: LIEDTKE RAINER K DR
IPC: A61K9/28
Filed: 1989-06-19
Abstract: To improve the absorption of actve ingredients, which are not adequately bio-available on oral administration, an oral lipid medicinal composition is formed by combining a semi-solid, lipophilic component with a solid, water-soluble component. The semi-solid component is a homogeneous lipid mixture that exists as a hard fat with thermally reversible fat/liquid melting property, at least 95% of which is present in the liquid aggregate state below the body temperature of 37 DEG  C. and comprises monoacyl-, diacyl-, and triacylglycerides of saturated vegetable fatty acids with chain lengths ranging from 6 to 18 carbon atoms, preferably comprising a mixture of 40 to 60% monoacyl- and diacylglycerides and 40 to 60% triacylglycerides, in which the active ingredients are either dissolved, suspended or emulsified. The solid component comprises a non-diffusible, water-soluble shell which is not chemically bonded to the lipid compound and envelops the entire lipid compound and is preferably made of gelatin or starch. The use of protease inhibitors in the lipid mixture can improve the permeation conditions for peptides and proteins. The use of highly disperse silicon dioxide can stabilize the suspension formulations. Physical-chemical and biochemical aspects of the oral lipid medicinal form yield improvements for the absorption of drugs that are not adequately bio-available on oral administration.

Filed: 1989-06-28
Abstract: The monitoring system uses a data telegramme monitoring signal which is transmitted in parallel with the digital communication signal switch regeneration and updating of the data telegrammes at each intermediate station between the end stations. When reception of the data telegramme at an  intermediate station is not obtained for a given interval, the intermediate station is switched into a start mode to begin  transmission of its own data telegramme. Each intermediate station monitors the correct reception of the transmitted characters and compares the bit error rate with a threshold value, to initiate the start mode. ADVANTAGE - Allows localisation of transmission fault.
