Title: Process and apparatus for drying a filter cake in a filter press
Inventor: NEU WERNER DR ING
IPC: B01D25/168
Filed: 1987-04-22
Abstract: The invention relates to a process and an apparatus for drying a filter cake in a filter press, in which, after draining the slurry, the filter cake is expressed by membranes impinged with compressed air then compressed air is passed through the filter cake, which compressed air is introduced on one side of the filter chambers and is conducted away on the opposite side. It is the object of the invention to markedly improve the efficiency of the drying of a filter cake with the aid of compressed air introduced into the filter chambers and to make it more economical as well as to unify considerably the degree of dryness of the filter cake. The invention comprises supplying heat to the filter cake while compressed air is passed through it.

Title: Infrared soldering furnace for reflow soldering of electronic components on printed circuit boards
Inventor: HIMMELREICH LOTHAR DIPL ING
IPC: B23K1/008
Filed: 1987-05-13
Abstract: In an infrared soldering furnace for reflow soldering electronic components on printed circuit boards 38 using a solder paste, said printed circuit boards rest on a support (support surface 37) which is transparent to infrared radiation. Infrared radiators 39-42 which heat the assembled printed circuit boards 38 during a heating phase and a melting phase at different temperatures are arraanged above and below the support. The printed circuit boards 38 are then cooled. A drawer 27 on whose support surface 37 the assembled printed circuit boards are placed is provided for introducing the assembled printed circuit boards 38 into the infrared soldering furnace. During the heating phase and the melting phase of the solder paste, the drawer is fixed in the housing. The infrared panel radiators 39-42 have a low thermal intertia and are arranged parallel to the support surface 37 at distances large enough to ensure they heat the support surface uniformly. The support or the support surface 37 and the infrared radiators 39-42 are arranged in a forced-draught exhaust-air duct 2 in the infrared soldering furnace. The infrared radiators 39-42 are powered by a time-controlled temperature control device 25 so that the stationary, assembled printed circuit boards are heated with the desired temperature profile. <IMAGE>

Patent DE-3743024-A1 (DE)
Inventor: KOERNER KARL
IPC: E04F13/08
Filed: 1987-12-18
Abstract: Facing slabs can be suspended on transverse struts or the like by means of shackles attached to their rear side. In the process, the shackles, which can be produced from angled flat steel, have to be securely fastened to the rear side of the facing slab. A secure fastening of the shackles to thin-walled facing slabs is achieved by using a fastening element which possesses an expanding member. The expanding member engages in a blind bore provided on the rear side of the facing slab and is clamped therein. The shackle is secured by means of a retaining cap engaging over the expanding member. <IMAGE>

Patent DE-3802338-A1 (DE)
Title: Support stocking
Inventor: JESCHKE IMMANUEL
IPC: D04B1/26
Filed: 1988-01-27
Abstract: The invention relates to a support stocking which comprises a stocking-like, elastic, textile sheet-like structure and elastic means for holding the sheet-like structure on the leg. It is the object of the invention to create a support stocking which shows only little tendency to slip and is more comfortable to wear and at the same time displays its supporting effects better. The invention resides in the fact that the textile sheet-like structure has very little stretching ability in the longitudinal direction of the stocking and can be stretched elastically in the transverse direction only.

Patent DE-3839343-A1 (DE)
Title: Ultrasound camera
Inventor: LOEBBE GERON A
IPC: H04N5/30
Filed: 1988-11-22
Abstract: Sound can be processed "optically" as light. A generated sound picture (image) is converted into electrical signals with a selective pressure-sensitive sensor field, which signals are processed to obtain a video picture. To prevent sound disturbances from outside, the frequencies which deviate from the transmitting frequency are filtered out. To obtain a high picture quality, high-frequency ultrasound is used as far as possible. The sound signals are reflected by the object in varying intensity depending on material and surface condition. The sensor consists of small piezoelectrical elements (grid size in the range of tenths of mm to 1  mu m). Applications. Working in muddy waters. In the case of very high sound intensities, also in marine research for relatively large areas and depths. Field of medicine: for "transilluminating" body parts; as aid for examinations (conventional devices do not have the high resolution). When using different frequencies simultaneously, it is possible to produce "colour pictures" (each frequency represents a colour). By using the Doppler effect it is possible to detect specifically only moving objects.

Patent DE-3908434-A1 (DE)
Title: Device for correcting feed axes
Inventor: DRASSDO BERNHARD DR ING
IPC: B23Q15/18
Filed: 1989-03-15
Abstract: The invention relates to a device for correcting a feed axis and is used on feed axes with rotational drive and translatory movement by means of a rolling screw drive. To this end, the screw-drive spindle is coupled directly to a force or torque source or via interposed mechanisms and an axial bearing, and furthermore a drive control loop for the feed movement is connected to a correcting control loop for the axial loading of the screw-spindle drive. The force made available produces an additional translatory movement through elastic deformation in the course of the axial support of the slide drive, as a result of which the axial reference base of the rotationally initiated feed movement is displaced in a correcting manner in such a way that the desired value and actual value of the position coincide without action having to be taken in the rotational train of the feed drive.

Title: Thyristor with anode-side emitter short-circuits - has inserted P-conductive zone for reverse blocking capability
Inventor: OPPERMANN KLAUS-GUENTER DIPL P
IPC: H01L29/08
Filed: 1989-05-31
Abstract: A thyristor has a p-emitter (4) contacted by an anode-side electrode (5) at the anode-side face (12), an n-base (3), a p-base (2) and an n-emitter (1a-d) contacted by a cathode-side electrode (6-9) at the cathode-side face (17), the p-emitter (4) having recesses (10) filled with n-base extensions (11) which extend to the anode-side face (12) and are contacted by the anode-side electrode (5). A reverse blocking capability is produced in the n-base (3) by insertion of a thin p-conducting zone (14) which runs parallel to the pn-junction (15) between the two base layers (2, 3). The doping concn. of the inserted zone (14) is greater than that of the n-base (3), the difference being determined by the value of the max. blocking voltage in the reverse direction. ADVANTAGE - Reverse blocking capability in spite of presence of anode-side emitter short-circuits.

Title: Test body and test device for spray sterilisers - has easily removable ends so that inaccuracy in test result due to in accessibility of parts of body
Inventor: VETTER KLAUS DIPL ING
IPC: A61L2/28
Filed: 1989-06-05
Abstract: The test body has at least one point of reduced cross section, which is formed by one or two notches which have flat intersecting sides or curved sides. A perforation may be provided between the end or ends of the test body and the cross section reduction(s).. The test body or bodies are clamped into a test device, which is also provided with hooks located to suit the distance between the perforations in the test pieces. USE/ADVANTAGE - This invention is used for testing the effectiveness of spray sterilisers, which are used for disinfecting equipment and furniture in hospitals. It is proposed that the clamp which holds the test body should remain in the test device and that the ends of the test body should be removed after the sterilisation process is complete, so that the contamination introduced or retained by the clamp is eliminated. The accuracy of the test is therefore greatly increased.

This insulator is pref. a foil of plastics material with adhesive at the edges. USE/ADVANTAGE - Cheaply and simply converting operating panel to suit individual requirements, e.g. common panel made for all models and reducing number of functions for simpler models. Removing functions not required to make operation simpler and avoid mistakes.
