Title: Cooling box for conducting away the waste heat from semiconductors
Inventor: KLEIN ERWIN
IPC: H01L23/473
Filed: 1987-11-27
Abstract: The invention relates to a cooling box for conducting away the waste heat from semiconductor elements, in particular power rectifiers, consisting of two shells with a connecting element for feeding in and carrying away the cooling fluid (service water) with flow obstacles (cooling ribs) provided inside the shells and with contact panels for receiving the heat emitted by the semiconductor element and for distributing it to the cooling fluid. A cooling box is to be provided which can be cooled with normal water, i.e. with service water, and in which no glow discharges occur and the cooling boxes themselves are to be voltage free. In addition, a compact design of the rectifiers is to be obtained. This is achieved in that, using service water as the cooling fluid, an insulating panel made of inorganic insulating material is arranged between the contact panel and the shell, the diameter of the insulating panel being greater than the diameter of the shell and of the contact plate.

Title: Arrangement for increasing the expected service life of matrix print heads
Inventor: MILBRANDT ARTHUR
IPC: B41J2/235
Filed: 1988-02-26
Abstract: The print head of a matrix printing device has, in addition to the number of first printing elements required as a minimum for the printing operation, further printing elements which adjoin the first printing elements in such a way that the overall arrangement of the printing elements can be subdivided into two overlapping partial arrangements of printing elements, such that the one or the other partial arrangement can be used alternately for printing. In this case, the switch-over between the two partial arrangements takes place either by changing the paper feed or by vertical displacement of the print head with simultaneous electronic switch-over of the drive for the individual printing elements. <IMAGE>

Patent DE-3808771-A1 (DE)
Title: Rolling contact mechanism
Inventor: RUEHLEMANN JOACHIM
IPC: F16H15/50
Filed: 1988-03-16
Abstract: The invention relates to a mechanism which is theoretically suitable for reductions of between i = 0 and i = infinity. The mechanism operates with two stages. A speed reduction is achieved by the fact that rolling elements with different, variable effective radii roll upon one another and can produce relative motions in different directions of rotation which give a total movement of the output shaft which is a selectable rotary motion in the same or the opposite direction with the desired speed reduction relative to the input shaft. The principle of operation permits the use of gear wheels but also of friction wheels or belt pulleys and, in the case of the last-mentioned types of wheel, spring elements, preferably Belleville springs, produce the required contact pressure. In the case of drives where noise is an important consideration, mechanisms in which tensile transmission elements, for example O rings, are used to transmit the speed and torque because of their vibration-damping characteristics appear expedient. Finally, it is also possible to produce mechanisms based on friction wheels or belt pulleys made of plastic for small motors. It is also possible to construct mechanisms in which the speed variation is effected by means of a flexible pulley that bends easily. Depending on their size, of course, the predominant feature of these mechanisms is their radial construction and small axial dimensions.

Title: Continuous process for the purification of solvent-containing exhaust air with recovery of the solvent
Inventor: NGUYEN VINH NHU DIPL ING
IPC: D06F43/08
Filed: 1988-07-15
Abstract: Exhaust air having high solvent concentrations is first cooled, with the majority of the solvent being recovered by condensation. The further purification is carried out by adsorption in an adsorber. The desorption of the loaded adsorber is carried out at relatively high temperatures. The majority of the desorbed solvent is recovered by condensation at low temperatures. A heat pump is used for the cooling and heating. When a compression heat pump is used, by utilising the superheating heat of the working medium of the heat pump in the compressor, and when an absorption heat pump is used, by utilising the exhaust gas heat of the expeller, the heat transport stream used for the desorption is heated to temperatures which are considerably above the condensation temperature of the working medium of the heat pump.

Title: Finishing of textile web materials patterned by the thermal-transfer printing process with a metallising pattern
Inventor: KLEBER KURT
IPC: D06Q1/04
Filed: 1988-08-02
Abstract: Method for printing textile web material, in which a web of thermal-printing paper is applied to the side of the textile web material to be printed and the two webs are then guided through the roller nip of at least one synchronously driven heated pair of rollers, the printing pattern located on the thermal-printing paper being transferred onto the side of the textile web material facing it. Before the printing operation, a hot-melt adhesive having low viscosity in the application state and taking the form of fine droplets of hot-melt adhesive is sprayed onto the side of the thermal-printing paper provided with the printing pattern to be transferred, and during the subsequent printing operation the pattern of sprayed-on droplets of hot-melt adhesive is transferred, at the same time as the printing pattern, onto the side of the textile web material to be printed. The metal-coated side of a web of metallised foil is applied to the side of the textile web material printed in this way, and the webs lying one on the other are guided through the roller nip of at least one synchronously driven heated pair of rollers. After the subsequent separation of the two webs lying one on the other, a metallising pattern corresponding to the pattern of sprayed on droplets of hot-melt adhesive remains on the printed textile web material.

Title: Method for photometric measurement on liquids
Inventor: BAUMERT DIETER DIPL PHYS
IPC: G01N21/85
Filed: 1988-08-02
Abstract: The invention relates to a method for photoelectric measurement on liquids to satisfy analytical tasks such as, for example, to determine selected components in blood and to examine ground samples, and to solve monitoring problems, such as, for example, monitoring of boiler feed-water, or of processes in the food industry, the photoelectric measuring signal representing a quantitative or qualitative statement about the original sample to be assessed. The method can be used both for continuously flowing sample streams and for working on samples discontinuously and discretely. The method is realised by generating a measuring fluid stream and introducing into this a measuring radiation, subsequently leading measuring fluid stream and measuring radiation without guidance over a path and, at the end of the path, abruptly separating them, before the separation the still-focussed measuring radiation, and/or after the separation the scattered measuring radiation component being fed to at least one radiation detector and fed from this to an evaluation unit and a rinsing of the separating location being carried out after each measurement.

Patent DE-3843050-A1 (DE)
Title: Electric acoustic transducer
Inventor: TAKEUCHI AKIHIKO
IPC: H04R1/30
Filed: 1988-12-21
Abstract: In a design of an electric acoustic transducer, such as, for example, a loudspeaker for musical instruments, a sound generating unit is fixed close to the open end of a resonant pipe and connected to a partition which has a central passage aperture and extends over the complete extent of an elongated cavity in the resonant pipe. For complicated resonance modes and rich acoustic vibrations, two or more resonant pipes of different types can be used in combination with one or more sound generating units. The presence of such a partition clearly defines the length of the resonant air columns which are generated in the resonant pipe, and such a cleanly cut-off resonant air column effects high sharpness of resonance.

Title: Process for separating out solids from a solid/liquid mixture
Inventor: GERLACH KAY DIPL ING
IPC: B01D35/147
Filed: 1989-01-27
Abstract: Apparatuses of this type, that is rotary sieves (10), have a tendency, particularly in the separation of solids, to blockages of the screen drum (12). The consequence is interruption to operation. The invention is to create a rotary sieve (10) in which blockages can be eliminated without significant interruptions to operation. In the apparatus according to the invention (rotary sieve 10), a bypass (40) is provided through which the solid/liquid mixture can be diverted around the screen drum (12) in the event of a blockage of the rotary sieve (10). As a result the screen drum (12) is accessible for elimination of the blockage or other operating faults. The invention is particularly suitable for rotary sieves (10) which are used for treating pulps in a sugar beet factory. <IMAGE>

Title: Microprocessor-controlled device for managing and controlling all types of electronic and musical instruments and peripheral devices
Inventor: AMBRUSCH HARALD
IPC: G10H1/00
Filed: 1989-01-28
Abstract: It is the aim of this invention to give to a musician (instrumentalist) the possibility of managing centrally each device belonging to his musical environment, of operating them in any configuration appearing sensible to him, and of altering the control parameters of the devices in any desired way and at any time. This task should not, however, deflect him from his primary activity of making music. These claims have been realised in that, firstly, by means of a device, modified devices can be controlled, devices of any desired power operated by or processing alternating or direct current can be switched and alternating and direct current processing devices of any desired power can be integrated into one (or more, if necessary parallel) signal chain(s). Secondly, the entire operation and programming of the control device can be undertaken by means of a so-called foot-board (possibly of higher order) and the respective configurations are stored. These two components make it possible for the many switch-overs, etc., impossible to carry out at the same time in the normal case, can be triggered by means of actuating a key. The targeted groups are instrumentalists, musical groups, sound studios. For example, one musician in a group playing "live" can control the entire equipment of the group, including the stage lighting.
