Patent DE-3220344-A1 (DE)
Title: Electrical immersion-bath heater
Inventor: ROECKERT LEO
IPC: H05B3/78
Filed: 1982-05-28
Abstract: The invention relates to an electrical immersion-bath heater having an electrical heating insert which is at least partially surrounded by a protection device which is connected to the earth conductor and consists of electrically conductive material. Such immerson-bath heaters are used for tempering fluids of highly varied constitution, especially for heating fluids whose precise temperature setting is important for the sequence of processes controlled by the fluid. Photographic developing solutions should be mentioned as an example here. The immersion-bath heater according to the invention is distinguished by an electrically conductive outer tubular jacket, which is insulated from the electrical protection device. As a result of the insulated arrangement of this tubular jacket, metal depositions and/or pitting on the tubular jacket are prevented, as occured in the past in known immersion-bath heaters having a metallic tubular jacket. <IMAGE>

Title: Hybrid liquid gasification nozzle
Inventor: KUNST BERNHARD PROF DIPL ING
IPC: B01F5/04
Filed: 1982-07-03
Abstract: A device for the gasification of liquids, consisting of two chambers for gas and liquid which are separated by a gas-permeable wall (e.g. a porous layer or a perforated sheet). The gas has a slight overpressure relative to the liquid. As a result, it passes finely distributed through the wall and enters into the liquid. The liquid, a circulation stream taken from the gasification container, is passed by the wall at an increased speed. As a result, the gas entering is broken up into very fine bubbles and transported into the reaction container by the circulated liquid. An exemplary embodiment is illustrated in the figure. The aim of the invention is to intensify the substance exchange in the reaction container and thus to reduce the container volume.

Title: Device for using the heat loss of friction driven hoists
Inventor: SCHROEDER HERMANN
IPC: F24J3/00
Filed: 1982-08-11
Abstract: The invention relates to a device for using the heat loss of friction driven hoists which for the purpose of reducing the motor speed to the speed of the driving pulley have worm gears whose negative property consists in the comparatively low efficiency. It follows from this that the worm gear (3) emits substantial quantities of heat to the environment, which in accordance with the invention can be absorbed by surrounding the drive device, consisting of the motor (1) and gear (3), with an oil-filled container (4) and thermal insulation (5), and can be passed on for purposive use. The invention can be applied to all hoist installations in which a rational use of exhaust heat is possible. <IMAGE>

Title: Demodulation circuit for frequency shift signals
Inventor: TAKEDA KOJI
IPC: H04L27/156
Filed: 1982-09-16
Abstract: A demodulator circuit for recovery of an originally binary signal which has been modulated by means of frequency shift keying (FSK) has N presettable counters (302 to 305) with which the length of the intervals between two zero transitions of a zero-transition signal recovered from the received FSK signal is determined. Through storage in each counter of the two's complement of a decision threshold value interval before each counting operation, the counter reading indicates at the end of the counting operation whether the measured zero transition interval is greater or smaller than the decision threshold value. For the purposes of reducing distortion, the N counters (302 to 305) count N zero transition intervals to provide the mean value of the intervals. The counter values pass via a multiplexer (116) to a register (201) and a further register (202) connected downstream of the latter in order to determine, through comparison of two consecutive zero transition intervals by means of a delay compensation circuit (203), a delay period by which the demodulated output signal is delayed so that the latter is rendered free from distortions which occur because a change in the demodulated binary signal can take place in conjunction with a zero transition only. The additional delay corresponds to an estimation of the time at which the change in the original binary signal occurs. <IMAGE>

Title: Training device for tennis players
IPC: A63B21/065
Filed: 1983-02-14
Abstract: In the sport of table tennis in particular, there are various types of shots by which the ball can be played in a particular way in order to make it difficult for the opponent to return the ball. The most effective, but also the most difficult type of shot is the so-called topspin shot, in which the ball is touched only obliquely with the bat or racket at maximum speed, in order to impart maximum rotation to it. Practising this shot requires explosive power training which should, however, be carried out under conditions which are as realistic as possible. This object is achieved by providing as a training device a sleeve for fastening to the lower arm and having a closable pocket which can be fastened to a sheet-like flexible supporting part and is intended for receiving a weight. <IMAGE>
Patent DE-3308994-A1 (DE)
Inventor: BIRK ADALBERT DIPL ING
IPC: G01S7/52
Filed: 1983-03-14
Abstract: A method and apparatus for processing ultrasonic echo signals employ intermediate storage and representation of the echo signals in the form of image vectors, such storage and representation proceeding independently of the scanning technique utilized to generate the image vectors, such that switching among various scanning techniques is permitted. The full length of each image vector is written into an image memory in column fashion, the stored vectors being read out as image signals in a format suitable for specific types of representation, such as on a television monitor, the format instructions being contained in a memory or generated by an arithmetic unit. Upon read out from the image memory, the geometric form of the ultrasonic scan is reconstructed in a position and form corresponding to the actual scan, and the ultrasonic echo signals are similarly represented at their true positions.
Patent DE-3311691-A1 (DE)
Title: Sliding finisher
Inventor: GEIGER LOTHAR DIPL ING
IPC: B28B1/08
Filed: 1983-03-30
Abstract: The invention relates to a sliding finisher for manufacturing prefabricated concrete structural elements, with form arrangements defining the structural element shape, with a concrete supply device and with at least one compacting device for at least the uppermost region of the structural element(s), at least the compacting device being movable relative to the structural element in the manufacturing direction. In known sliding finishers, vibrators, vibration skids or similar vibrating devices are used for compacting the concrete, which slide on the upper side of the structural element. As a result of the simultaneous influence of the vibration and the sliding friction, cracks can scarcely be avoided. According to the invention, however, this is avoided in that the compacting device has at least one vibration roller which rests on the upper side of the structural element, rolls off slip-free and the axis of rotation of which lies transversely to the manufacturing direction. As a result of the elimination of the friction of the compacting element on the upper side of the structural element, crack formation is avoided even in the case of thin-walled hollow structural elements.

Patent DE-3315038-A1 (DE)
Title: Apparatus for the treatment of solids
Inventor: STAHL WERNER PROF DR
IPC: B03B7/00
Filed: 1983-04-26
Abstract: The apparatus is used for the treatment of solids, in which apparatus a wash liquid flows through the solids by the counter-flow principle. The suspension is supplied to the apparatus via a feed duct and conveyed by rotating conveying devices through a series of troughs until it overflows. In the upper region of the apparatus, wash liquid is fed through the feed duct and flows downwards against the direction in which the solids are conveyed, and the mother liquor is conducted away via the discharge. The wet and washed solids are expediently fed to a centrifuge. Here the separation takes place into the solids, which pass to a reservoir, and the residual liquid; the filtrate residue is passed back into the system via an inflow device.

Title: Method for testing permanent-magnet segments and test instrument therefor
Inventor: BAUMANN ROLF
IPC: G01R33/12
Filed: 1983-07-11
Abstract: A method for testing permanent-magnet segments for magnetisability and durability and a test instrument therefor is specified in which, for the purpose of rapid testing with at the same time reliable reproducibility of the test values independently of segment tolerances and winding temperature and voltage fluctuations, the field strength is measured on the inside and/or outside of the magnetic segment and the counterfield is increased in dependence of time until a predetermined limit field strength (H2) is reached. The counterfield is then either switched off and the residual flux is measured or the flux is determined at the limit field strength (H2) reached and the counterfield is only switched off when the coercitivity field strength of the polarisation is reached. In the latter case, the magnetic segment tested is at the same time completely demagnetised again. <IMAGE>

Patent DE-3336339-A1 (DE)
Title: Sealing element for pipe connections
Inventor: HOCK KARL
IPC: E03F3/04
Filed: 1983-10-06
Abstract: Annular sealing elements are used for sealing, in particular, sewage pipes laid in the ground. Strong compression of the seals occurs as a result of the weight of the pipes themselves and the earth lying on them. In this case, the seals are so strongly compressed that, on the one hand, they lose their sealing effect and, on the other hand, the pipe parts rub directly on one another which results in peeling and leaks. The invention creates a sealing element which prevents the pipes bearing directly and reduces the compression effect of the seal to an acceptable level. For this purpose, the sealing element (4) consists of a sealing part (5) and a supporting part (6). In this case, the supporting part (6) absorbs the complete load of the pipe (1) or (2) respectively, while the sealing part (5) is tightened exclusively for sealing. <IMAGE>

Abstract: A magnetic stirrer (1) (Fig. 1) has a housing (7) for accommodating a drive motor (2) or the like, as well as further components. The motor drives a drive magnet (3) via which a stirring body (5) positioned in a vessel (4) can be set in rotation. The vessel (4) is positioned on a stand plate (8), which is generally designed as a hotplate. In order to avoid significant penetration of aggressive vapours or the like into the interior of the housing (7), the housing is designed so as to be largely tightly sealed. The bottom end thereof is formed by a baseplate (10). At the top, the housing is similarly sealed, apart from the passage for the motor shaft (13). For the purpose of removing the heat of operation arising particularly from the motor (2), a cooling body is provided which in this case is formed by the baseplate (10). At the top, the housing is shielded with respect to the hotplate (8) by a thermal shield comprising a ring-plate (17) and a spun plate (15). The spun disc (15), which is linked to the motor shaft (13) in a torsion-proof manner, also prevents penetration of liquid and the like through the housing top side (16) in this passage area of the shaft. <IMAGE>
