Patent DE-4331935-A1 (DE)
Title: Process for the preparation of polyurethane solutions
Inventor: DEUTSCH KLAUS
IPC: C08J3/09
Filed: 1993-09-16
Abstract: The invention relates to a process for the preparation of polyurethane solutions having a long shelf life which are free from gel particles, in which the molecular weight of the polymer can be controlled precisely. This allows, for a fixed solids content of between 5 and 30%, the viscosity of the solution to be set reproducibly. The process according to the invention allows the concomitant use of polyfunctional hydroxyl compounds in the chain extension phase. It thus advantageously leads to constant viscosity/solids content ratios and to solutions having stable viscosities, these solutions being substantially insensitive to the water content of the solvent and virtually free from gel particles. Polyurethane solutions of this type can be used as the starting material for fibres or as textile coating material. Microporous or dense films can also be produced from these solutions by corresponding technological processes.

Title: Method and device for the preparation of materials samples for examinations of materials
Inventor: MENZEL SIEGFRIED
IPC: G01N1/32
Filed: 1993-10-13
Abstract: When producing oblique cuts on material samples by means of the ion beam method, it is a disadvantage that high-accuracy positioning of the cut with the aid of a mechanical diaphragm requires the presence of a plane sample surface and an expensive vacuum feed-through for the movement of the diaphragm on the scanning electron microscope (SEM). With the aid of the novel solution, it is intended to be possible to carry out high-precision positioning of accurate cuts with selectable edge profile in the microscopic range, while avoiding mechanical diaphragms. According to the invention, a structured contamination layer is produced on the material sample by using a moved electron beam in a carbon-containing gas with a pressure below 130 Pa, which layer serves as an etching mask and is subsequently etched in plasma discharge with reactive or unreactive ions. A device used for this purpose is characterised in that the sample support (1) is located in a housing having a gas supply (3) for the material sample (5), in that an electrically insulated, earthed electrode plate (9) having a transmission window for an electron beam is arranged in the sample support (1), in that the material sample (5) can be connected alternately to earth potential or, relative to the electric plate (9), to the radio-frequency voltage, and in that the device is in its entirety mounted displaceably and rotatably. The invention is... in the microanalysis of materials, preferably ...   Original abstract incomplete. <IMAGE>

Title: Parking system for accommodating, for setting down and for returning vehicles, having any number of vertical lines, any number of horizontal storeys and any number of rows
Inventor: REITEMEIER KARL
IPC: E04H6/22
Filed: 1993-11-08
Abstract: The invention relates to a three-dimensional parking system for accommodating, for setting down and for returning vehicles. In contrast to known parking systems, the novel parking system is intended to increase the utilisable parking area, to accelerate parking and departure, and to achieve independence from buildings. This object is achieved by flexibly usable cells which are arranged one beside the other, one on top of the other and one behind the other. Depending on the degree of occupancy and the cell which is to be activated, through-passage transporting alleys are set up, and only a small number of cells is to be kept free. In the grid dimensions of the cells, adaptations to specific formations of the terrain are possible, and protection against the weather can be achieved by measures taken on the exterior cells. This parking system can effectively counteract the lack of parking and garage spaces in towns and highly frequented destinations (company buildings, local authority buildings, shopping centres, schools, sport centres and conference centres, etc.).
