Patent DE-3003340-A1 (DE)
Inventor: KLEINERT HELMUTH
IPC: G06F13/22
Filed: 1980-01-30
Abstract: A method and a circuit arrangement are disclosed for transmitting binary signals between peripheral units which are connected to one another via a central bus line system. The signal transmission is to take place without the necessity of including a central processor, which is likewise connected to the central bus system. For this purpose, it is provided that signal transmission requests from the individual peripheral units are transmitted to a memory access device which is also connected to the central bus line system and which, in response to the receipt of such transmission request, de-activates the central processor in respect of the transmission of signals to the central bus line system. The memory access device supplies the peripheral units which are to participate in a signal transmission operation with control signals which transform the latter from a starting state into a transmitting state or into a receiving state and then, in alternation with control signals which serve for the output and receipt of signal groups. Following the transmission of the last signal of the number of signals reported to the memory access device in respect of a signal transmission operation, the memory access device supplies the peripheral units with a reset signal by which the same are returned from their transmitting and receiving states into their starting states.

Title: Photomask for mfg. very small semiconductor structures - where metal mask pattern is located on raised zones of glass substrate
Inventor: KRAFT WOLFGANG
IPC: G03F1/00
Filed: 1980-04-19
Abstract: The mask consists of a transparent substrate on which a continuous masking material (I) is deposited and then etched by photolithography to leave a mask pattern (Ia). The substrate is next selectively etched so the pattern (Ia) is located on raised zones of the substrate. Layer (I) is pref opaque and made by the vapour deposition of a metal such as chromium. The pref mask making method consists of coating a substrate with a metal (I), which is etched via a photolacquer mask to obtain pattern (Ia). The substrate is then etched to leave projecting zones on the pattern. The projecting zones are removed. Layer (I) may alternatively consist of semitransparent Fe203 or Cr203. Used e.g. in mfg semiconductor structures 1 micron wide using electron beams or X-rays as the exposure medium. The mask provided reduces the scatter of electron- or X-ray- beams, and is inexpensive.

Title: Instrumentation surveillance from central point - using single coaxial cable bus and HF frequency shift signalling
Inventor: KRUEGER HASSO ING GRAD
IPC: H04L5/06
Filed: 1980-05-08
Abstract: Both the central point and the distant instruments are associated with standardised units using binary h.f. data. Each instrument station uses two distinct frequencies allotted to it for representing a logic '1' and logic '0', e.g. 2,225 KHz and 2,025 KHz respectively, the central station using the frequencies 1,270 and 1,070 KHz respectively. Active filters are used to produce 40 db attenuation neighbouring frequencies. Each instrument has its own address and, on being called, automatically sends out a status word and relevant extra data to the central station. The uniform structure of the interface units, the easy check on performance, the ability to extend the system from any point, and the min. wiring, are some of the claimed advantages.

Title: Electro-acoustic transducer for headphones or loudspeaker - uses permanent magnet, coil and membrane of magnetisable material
Inventor: REHER HANS-ADOLF
IPC: H04R13/00
Filed: 1980-05-30
Abstract: The transducer consists of a pot magnet with openings for allowing the sound to be transmitted, over which, a rubber sleeve is fitted. The inner end of the rubber sleeve is chamfered inwards, and has a plate-shaped membrane over this end which acts as a bearing surface for the membrane, and allows its surface to expand or contract, depending on loading. These three components are inside a tube which forms the housing, the pot magnet being firmly fixed inside the rubber sleeve so that the membrane has a small clearance between its surface and the end of the magnet. A coil with a half-shell core is fixed with adhesive to an angled metal bracket which also serves as an anchor for the connecting cable. The distance of the coil core to the membrane is double the distance of the latter to the magnet. For connecting to the ear, a soft P.V.C. tube is pushed into the rubber sleeve, thus being easily removable for cleaning.

Title: Tuning detector for frame antennas
Inventor: BRANDT HANS-JOACHIM
IPC: H03H7/40
Filed: 1981-03-26
Abstract: The present invention relates to a tuning detector for a frame antenna (RA), which is provided with a tuning capacitor (C1), using a 90 DEG  phase detector (PD) which has two measurement inputs (A, B) and error voltage compensation (CD). For automatic tuning with a large catchment band, it is proposed to provide the tuning capacitor, in a manner known per se, between the connecting points (1, 1') of the frame antenna, and to supply the frame antenna via an impedance converter (IW) and two coupling capacitors (C2, C2') which are connected to the connecting points of said frame antenna, so that the two measurement inputs of the 90 DEG  phase detector can be connected to the two connections (1', 2') of one of the two coupling capacitors. A frame antenna which is equipped with the tuning detector according to the invention is particularly suitable for use as a transmitting antenna in the short-wave (high frequency) band. <IMAGE>

Title: Electrode of stable structure for solid-state electrolytes for electrochemical applications, and use of such an electrode in electrochemical sensors for determining the oxygen content in gases
Inventor: FRIESE KARL-HERMANN DIPL PHYS
IPC: H01M8/1213
Filed: 1981-03-31
Abstract: A highly loadable electrode of stable structure for solid-state electrolytes for electrochemical applications is proposed which contains a metallic component which catalyses the establishment of a thermodynamic gas equilibrium. Instead of the conventional platinum, the electrode contains at least predominantly rare metals having a melting point of less than 1600 DEG C, and a temperature-resistant, electronically conductive non-metallic solid. The rare metals which can be used are preferably silver and/or palladium, while especially an oxide of the Perovskite type is used as the electronically conductive non-metallic solid. The electrode has proved suitable especially in an electrochemical sensor for the determination of the oxygen content in gases, according to the attached drawing, where it can be used above all as an internal electrode exposed to a comparison gas, even though the measuring electrode can also be designed in this way. It is thus possible to replace the otherwise conventionally used expensive platinum in such electrodes by less expensive rare metals without functional detriment. <IMAGE>
Patent DE-3112927-A1 (DE)
Title: Distributing device for double circuit central lubricating system
Inventor: KNAEBEL HORST
IPC: F16N25/00
Filed: 1981-03-31
Abstract: In double-pipe central lubricating systems for grease or highly viscous oil, distributing devices are provided between a reversing device and the lubricating points and allocate cyclically metered-out quantities of lubricant to the lubricating points. These distributing devices operate in dependence on the change in the pressure gradient between the two supply pipes. One disadvantage of known distributing devices was the high outlay on construction and manufacturing equipment, as two parallel casing bores for a metering piston and a control piston and corresponding connecting channels between these bores were necessary in a relatively large casing. The object of the invention is therefore to bring about a considerable simplification of the structure of such a distributing device, and of the equipment used to manufacture it. This object is achieved in that the metering piston and the control element are arranged, one inside the other, in a single casing bore, and, with their relative movements, automatically execute the control actions which are necessary for the measuring out and allocation of the measured-out quantities of lubricant to the lubricating points. An arrangement of sealing surfaces on closure parts in the casing bore, which surfaces interact with the interior of the control element which takes the form of a reversing sleeve, is also particularly advantageous. The casing dimensions can be reduced considerably. The outlay on construction is small, as the second casing bore and connecting channels leading to this casing bore are no longer necessary.
Patent DE-3116209-A1 (DE)
Title: Cleaning device for a copier
Inventor: MIDORIKAWA AKIRA
IPC: G03G15/30
Filed: 1981-04-23
Abstract: A cleaning device for an electrophotographic copier can be operated in a first mode in which a film-forming material having a low coefficient of friction is applied to one surface of a photosensitive part, which has previously been subjected to a cleaning, in order to improve the cleaning action, or the cleaning device can be operated in a second mode in which such a material is not applied to the photosensitive part. To this end, the cleaning device exhibits a brush which can be brought into contact with the photosensitive part and can be removed from contact with said photosensitive part, in order selectively to apply the film-forming material to the photosensitive part. The brush is designed as a rotating brush which is brought by pressure into contact with a shaped block of this material. The application of the appropriate quantity of material is ensured in that the period of time during which the brush is in contact with the photosensitive part and the contact of the brush with the material block etc. are controlled appropriately.
Patent DE-3118057-A1 (DE)
Title: Connecting terminal for electrical lead wires
Inventor: FUCHS HELMUT
IPC: H01R4/48
Filed: 1981-05-07
Abstract: In the case of a connecting terminal for electrical lead wires, such as plug connectors, plug or socket strips and the like having a housing consisting of insulating material and having at least one multiple-limbed contact spring (which is accommodated therein) of which at least two limbs are connected to one another by means of an essentially U-shaped apex web, which has an insertion opening for the lead wire with which contact is to be made, and having a switching element which can move relative to the contact spring and moves one limb of the contact spring relative to another and towards this limb in such a manner that at least one clamping tab, which is allocated to a limb, presses the lead wire in a sprung manner against the other limb, the present invention proposes that the terminal be arranged in the immediate vicinity of the insertion opening and that the switching element acts on the moving limb of the contact spring on that end region of this limb which is remote from the insertion opening and the terminal. As a result of skilful construction and arrangement of the contact spring, and maintaining the principle of insertion of the lead wire without use of force, this results especially in it being possible to increase considerably the contact forces acting on the lead wire and, primarily, makes it possible to be largely independent of tolerances which have to be accepted structurally.
