Patent DE-3644371-A1 (DE)
Inventor: LENZ RUEDIGER
IPC: C07C217/04
Filed: 1986-12-24
Abstract: Polyamines based on derivatives of 1,3-bissubstituted 2-propanol containing a multiplicity of amino groups, the latter containing at least one primary amino group and additionally further N-basic groupings, prepared by reacting 1,2,3-trisubstituted propane compounds with bis(primary amines or with monoamines and bis(primary amines). The polyamines according to the invention are clear to yellowish or yellow products which, at room temperature, form viscous to highly viscous liquids or may be paste-like or wax-like. They may be used, inter alia, advantageously as starting products for the preparation of thermosetting, in particular water-dispersible and cataphoretically depositable binders based on aminourethanes for coating solid substrates, in particular metals.

Patent DE-3706294-A1 (DE)
Inventor: GARNREITER FRANZ DIPL ING
IPC: B02C18/16
Filed: 1987-02-26
Abstract: The invention relates to a device for processing tissue parts 7, especially of an animal and/or vegetable nature, to form roastings, granulate, etc. by comminution and/or mixing by means of a cutting mixer with a rotating bowl 1 for receiving the tissue parts 7 and with rotating knives 3. To eliminate the frictional heat occurring during comminution, it is proposed, according to the invention, to mount a spray nozzle 6 for low-temperature liquefied gas outside the tissue parts in front of the knives 3 penetrating into the tissue parts 7, in the direction of rotation 5 of the bowl 1. The spray nozzle 6 is directed at a point of the tissue parts contained in the bowl located immediately in front of the knives penetrating into the tissue parts 7, in the direction of rotation 5 of the bowl 1. Sprayed liquefied gas is therefore introduced immediately by the knives penetrating into the tissue parts 7. Tissue parts 7 are prevented from freezing hard on the spray nozzle 6. <IMAGE>

Patent DE-3717856-A1 (DE)
Inventor: SISOV GENNADEVIC
IPC: B23K20/00
Filed: 1987-05-27
Abstract: A wire bond (5) is formed between conductive pads, (1, 2) of a case (3) and a crystal (4) of a semiconductor device. Bonding is performed by joining a wire by means of an ultrasonic bonding tool (6) to the conductive pad (1), followed by pulling the wire through the bonding tool (6) and joining it to the conductive pad (2). The pulling is performed along a path that determines the shape of the wire bond (5), by forming a portion (7) ascending for the conductive pad (1), while the bonding tool (6) and an XY table (11, Fig. 2) carrying the semiconductor device move relative to each other, a plastically deformed flexure point (8) at which the wire is fixed in position by an operative member (33, Fig.2) of a wire fixing unit (32), and a portion (9) descending to the conductive pad (2) formed by moving the bonding tool (6) down, while the operative member (33) is kept stationary with respect to the semiconductor device. A non-destructive testing unit (72, Fig.2) applies a stretch-out force (P) to the wire for testing the strength of the wire bond. <IMAGE>

Title: Use of vinyl chloride polymers as bulk density modifiers for polyvinyl chloride powder mixtures
Inventor: SPINDLER ERNST JOSEF DIPL PHYS
IPC: C08L27/06
Filed: 1987-06-25
Abstract: The bulk density of vinyl chloride polymers can be improved by adding, as modifier, up to 25 % by weight of a vinyl chloride homopolymer or copolymer of defined particle size as bulk density modifier to this base PVC. Particle size of the modifier resin is selected so that a bimodal distribution with respect to the mean particle size of coarse (base PVC) and fine component (modifier PVC) results. The inclusion of the PVC fine particles in the gaps between the PVC coarse particles results in an increase in the bulk density. If the particle sizes differ by a factor of more than 50, the bulk density of the base PVC can also be increased by reducing the friction between the base particles.

Title: Method of producing an electrode for generating high current densities at points, with a low electrolysis current
Inventor: LORCH HANS-WALTER DR ING
IPC: C25B1/00
Filed: 1988-05-13
Abstract: Divided cells are often used in electrochemical syntheses in order to prevent undesired side reactions and reverse reactions. In order to avoid the resulting expensive designs and modes of operation, a counter electrode is employed which, through its very small current-carrying area, reduces the reaction rate of the undesired reactions to such an extent that the use of undivided cells is possible. The current-carrying surface is finely distributed on a non-conducting base area; its size in proportion to the total area can be varied within practically arbitrary limits. Electrolyte channels may be integrated in the electrodes, which facilitates use in electrolysis cells using to the filter press principle.

Title: Metering device, in particular for use in conjunction with a shaker
Inventor: PETERSEN JENS
IPC: E01C19/20
Filed: 1989-02-02
Abstract: A metering device, in particular for use in conjunction with a shaker, and for delivery of a powdery or granular material, has a container for the material and a belt conveyor arranged below the container. The upper strand of the belt conveyor constitutes at least one part of the container bottom, and an outlet gap for the material is arranged between the upper strand and a rear container wall, seen in the conveying direction of the belt. A vibrator for vibrating the upper strand is arranged in the immediate vicinity of the outlet gap and below the upper strand. It is thus achieved that a movement of the material occurs at the gap opening, which prevents the latter becoming blocked. Furthermore, the material is fed continuously and in an unchanging quantity out of the gap by the conveyor belt.

Patent DE-3906747-A1 (DE)
Title: Charge air cooler
Inventor: ENGLER GUSTAV DIPL ING
IPC: F02B29/04
Filed: 1989-03-03
Abstract: The temperatures of the charge air which enters the charge air cooler are so high that it is possible for the water to vaporise locally on the pipes which are assigned to the inlet side of the charge air and through which cooling water flows, with subsequent condensation which can lead to undesired cavitation and to impairment of material. The invention proposes, in contrast to known designs, either to feed the pipes in the inlet region of the charge air directly with a partial flow of the cold cooling water or to provide a poorer heat transfer in this inlet region. The overheating of the water in the air inlet region can then be avoided by both measures. Charge air coolers for large engines and engines for commercial vehicles. <IMAGE>
