Patent DE-3217307-A1 (DE)
Title: Coding of Chinese characters for input into computers or teletype machines
Inventor: LI JINKAI
IPC: G06F3/00
Filed: 1982-05-06
Abstract: The attempt to produce Chinese characters in the form of a numerical code has already frequently been made. In all such attempts, complicated systems were developed or a thorough knowledge of the written Chinese language proved to be an indispensible prerequisite. According to the invention, the characters are coded in numeric representation in that a different one of a number of digits is allocated to the possible different lines or optional line combinations in characters and the order of the digits corresponds to the relative graphic positions of the lines, the most highly placed being used first, then the next highly placed and so forth, and in the case of lines at the same level, the order first runs from left to right. Optionally, the total number of digit positions in the code is limited for more complicated characters in that the lines not characteristic or not necessary for distinguishing the character from other characters are left out of consideration. Such a method is relatively simple and can also be understood by a person who has only a limited knowledge of the written Chinese language. In addition, the method according to the invention can be used for entering Chinese characters, for example into a computer, a telex or a teletype system and for creating a character dictionary.

Patent DE-3224149-A1 (DE)
Inventor: RICHTER ARNO
IPC: A01K63/04
Filed: 1982-06-29
Abstract: A supply apparatus for the enrichment of aquarium water with CO2 is described. For the purpose of increasing the diffusion surface, several containers open at the base are arranged above one another along a gas inlet pipe to be assembled essentially vertically. The CO2 gas introduced into the bottom container displaces the water and subsequently fills the above-assembled containers in a cascade in a type of pneumatic tank. The thereby increased contact surface of CO2/water effects a more rapid adjustment to the desired higher CO2 concentration. See FIG. 1.
Patent DE-3227682-A1 (DE)
Title: Integrated photodiodes as a wavelength-selective demultiplexer device
Inventor: BOERNER MANFRED PROF DR
IPC: H01L31/0232
Filed: 1982-07-24
Abstract: The invention relates to a demultiplexer device consisting of integrated photodiodes, which is suitable for integration with other electronic or electro-optical elements. If light of different wavelengths is radiated into the demultiplexer device, it is only light of chiefly one wavelength that is absorbed in the different spatial regions of the demultiplexer device. This is achieved by operating the demultiplexer device in wavebands having low absorption coefficients and by mounting reflectors in front of, between and behind the diodes.

Title: Lantern-gear arrangement on a face conveyor or the like for the advance of a mining machine, in particular a shearer machine
Inventor: BORGSCHULTE FRITZ
IPC: E21C29/02
Filed: 1982-08-14
Abstract: The invention relates to a lantern-gear arrangement for the advance of a mining machine, in particular a shearer machine, running on a face conveyor or the like. The lantern gear consists of individual rack sections which are connected to the trough pans of the face conveyor in such a way as to be movable to a limited extent in the longitudinal direction, which trough pans can be angled relative to one another. According to the invention, the rack sections are connected at their ends by tie members, preferably straps, in such a way that they can be angled relative to one another, which tie members limit the pitch errors (positive pitch errors) appearing at bends in the trough pans. At the same time, all rack sections are preferably arranged so as to be movable to a limited extent in the longitudinal direction relative to the trough pans carrying them so that maximum vertical bending of the trough pans is possible without the pitch errors at the joints of the rack sections becoming too large.

Title: Apparatus for circulating liquids and treating them with gas
Inventor: FUCHS HUBERT
IPC: B01F3/04
Filed: 1982-09-04
Abstract: The invention relates to an improvement of a spiral aerator according to DE-C 2461032 which is used in particular for aerobic-biological cold or thermophilic treatment of waste waters. At the free end of its hollow shaft, it carries a propeller composed of at least two screw-shaped spirals evenly distributed about the periphery of the shaft. At this end, which is to be submerged, an ejector action occurs at an axial gas outlet orifice as a result of the liquid flow directed through the spiral towards the end of the hollow shaft. The spirals which are concave at the front side have transition surfaces running from each of these front surfaces to the backs of the leading spirals in the direction of rotation, so that concave-curved vortex chambers are formed, in which string-shaped vortices are axially and centrifugally accelerated. As a result of particular shaping and arrangement of the transition surfaces and spirals towards the hollow shaft and axially beyond the gas outlet orifice, spreading out of the string-shaped vortices at the shaft end is prevented, the vortices meeting at a certain distance from the hollow shaft end in a node.

Title: The use of magnesium salicylate or magnesium acetylsalicylate
IPC: A61K31/60
Filed: 1983-11-11
Abstract: The present invention relates to an area of use of the magnesium salts of salicylic acid and acetylsalicylic acid. Although present-day medicine is aware of the beneficial properties of these organic metal salts for prophylaxis and therapy when there is a risk of thrombosis and for rheumatic disorders, no one has thought of making use of their bivalent activity (antithrombotic and spasmolytic) in the therapeutic treatment and in the prevention of coronary heart disease. The invention remedies this by pointing out for the first time this bivalent activity and recommending magnesium salicylate and/or magnesium acetylsalicylate as coronary therapeutic agent.
Patent DE-3341929-A1 (DE)
Title: Process for the releasable connecting of plastics parts to metal parts by means of a form-fitting snap connection produced by cementing (adhesion/form-fit connection)
Inventor: BEITZ WOLFGANG PROF DR ING
IPC: B29C65/00
Filed: 1983-11-21
Abstract: A snap connection for the detachable connecting of components requires a profiling on both components. At the metal side this can be produced only in a complex manner. On this basis, the invention has as object to connect even smooth sheets of metal to elastic plastics parts with a snap connection. Here, according to Fig. 2 the concave profile of the snap connection is to be disposed in the plastics part (a), whilst the convex profile necessary for the form-fit is to be produced in such a manner that the initially smooth metal part (b) is inserted into the plastics profile (Fig. 2/1) and bonded to this by means of a high-strength cement (c) in such a manner that a high adhesion strength is obtained on the metal side but only a low adhesion strength, if any, on the plastics side (Fig. 2/2). By means of cement (c) on the metal part (b), a convex profile (d) results, which can be used as snap element to the plastics concave part. Upon release of the connection the profile (d) formed by the cement adheres firmly to the metal side, whereas at the plastics side an easy release and elastic bending of the plastics profile is possible (Fig. 2/3). <IMAGE>

Patent DE-3343727-A1 (DE)
Title: Card reader for cash registers
Inventor: AWAKOWICZ ERWIN
IPC: G06K7/00
Filed: 1983-12-02
Abstract: Method for cancelling a card (5) which can be inserted in a movable card receptacle (1) of terminals and which contains value units. A good electrical connection between the contact points (4) of the chip on the card (5) and the contact springs (3) of an evaluation device is intended to be ensured using simple means. For this purpose, the card (5) is first inserted in the card receptacle (1) without making contact, the contact points (4) on the card (5) being connected, by moving the card receptacle (1), to the contact springs (3) of the evaluation device by means of a fixed-position pressure strip (17) only once the receptacle is in its final position. Undesirable dragging of the contact springs (3) of the evaluation device over the card (5) and wear of the contact surfaces are thus prevented. Card readers of this type can be used, for example, in telephone system devices. <IMAGE>
