Patent DE-3335778-A1 (DE)
Title: Capacitive proximity signalling device which can be calibrated
Inventor: REICH STEFAN
IPC: H03K17/955
Filed: 1983-10-01
Abstract: A capacitive proximity signalling device, in which a fed-back amplifier circuit oscillates depending on the proximity of an object to a capacitive electrode. The connection of a special non-linear transmission element into the feedback path results in the oscillation not starting or terminating suddenly but its amplitude being proportional to the distance, or inversely proportional thereto (depending on the design). In consequence, precise distance measurement is made possible. Three different circuit principles are described as examples, the non-linear element in each case being of different construction. The oscillation amplitude may increase or reduce on proximity. The essential feature is the possibility to compensate completely for the non-linear characteristic of the capacitance change at various distances and to make it possible to calibrate the distance setting.

Title: Process for expressing cocoa mass
Inventor: BAUERMEISTER JOACHIM DIPL ING
IPC: A23G1/08
Filed: 1983-10-25
Abstract: The process for expressing cocoa mass and cocoa cake is carried out in a screw press (expeller). Addition of crystalline sugar surprisingly prevents the cocoa mass from passing through the screen rods and from not sticking to the screw more strongly than to the screen. The sugar acts as a filter aid, that is it assists in the formation of the required structure which then leads to the formation of the expeller cake. Furthermore, the sugar acts as a grinding aid.

Title: Device for controlling the choke on a carburettor for internal combustion engines
Inventor: HOSER ALFRED
IPC: F02M1/14
Filed: 1983-10-28
Abstract: The invention relates to a device for controlling the choke on a carburettor for internal combustion engines, especially in motor vehicles, with a pneumatic control element, which as a function of the pressure in the intake pipe of the internal combustion engine in a first stage opens the choke by a first defined gap dimension when the internal combustion engine is cold and with a time delay in a second stage opens the choke by a further dimension, a third opening stage being provided for a further reduction of the fuel consumption and pollutant exhaust emissions, in which third stage the choke is opened by a third, largest gap dimension and which by means of time- and/or temperature- dependent control devices can be switched on in addition to the second stage with a time delay.
Patent DE-3400024-A1 (DE)
Title: Envelope for packing and filing a flat article
Inventor: BENES JOSEPH J
IPC: B42F7/00
Filed: 1984-01-02
Abstract: An envelope (10) is used for packing, displaying, storing or filing magnetic discs (D) for computers. A first sheet (12) and a second sheet (14) form a first pocket (E1) and a second pocket (E2). The first pocket (E1) receives the magnetic disc (D), whereas the second pocket (E2) preferably serves to receive an index card (26), in order to facilitate subsequent filing and indexed classification of the disc (D) contained in the envelope (10). A tear strip (30) for opening the first pocket (E1) consists of a part of the first sheet (12) and is separated from the rest thereof by separation lines (32). The magnetic disc (D) can thus be stored in the envelope (10) in a protected and substantially sealed state, removal of the tear strip (30) giving access to the pocket (E1) containing the disc and providing a clear optical indication that the envelope (10) has been opened. <IMAGE>

Title: Fibre-reinforced concrete
Inventor: MERZ ALWIN DIPL ING
IPC: B23P17/06
Filed: 1984-09-29
Abstract: In the case of a reinforced concrete having short steel fibres uniformly distributed in the concrete, it is provided, in order to improve the bending tensile strength and to avoid rusting of the steel fibres at the surface, that each steel fibre is uniformly profiled transversely to its longitudinal extent, the fibre preferably exhibiting an elongate portion and in each case one corrugation at the ends, and the free ends and the elongate portion being located in different planes. Steel fibres of this type can be produced simply and cost-effectively by means of an apparatus which exhibits at least two bevel wheels which mesh with one another. One of the wheels is free of teeth over that length of its circumference which corresponds to the elongate portion, whilst on the other bevel wheel a cutting device for cutting the profiled steel fibre to length is provided on individual teeth.

Title: Method of operating fluidised-bed furnace units so as to reduce CO emission
Inventor: HOELTER HEINZ DIPL ING
IPC: F23C10/28
Filed: 1984-12-12
Abstract: In order to avoid, during the start-up and shutting-down of fluidised-bed furnace boiler units, increased CO generation during these phases, it is proposed according to the invention to switch the combustion air on or off with a time delay relative to the coal feed. Before the fluidising air is switched off, the coal feed is interrupted as a function of the temperature gradient of the hot water or of the increase in steam pressure on switching-off, and the air feed is correspondingly delayed in time, so that the coal proportion in the glowing bed is corresponding reduced. The required time interval in switching-off between coal and air is controlled by computer as a function of the temperature gradient or pressure increase.

Title: Plant for mixing wastes with, and incorporating wastes into, matrix substances
Inventor: SPIELER KLAUS
IPC: G21F9/02
Filed: 1985-10-11
Abstract: The invention relates to a plant for mixing wastes with, and incorporating wastes into, matrix substances, volatile and/or vaporous portions of the wastes being produced, which are conducted away through an exhaust air channel. The object of the invention is to create a plant with which both the filtering of the pollutants resulting in the conditioning is made possible and the secondary conditioning of the loaded filter system is facilitated. Instead of the conventional filter materials, in the invention the filter unit is replaced in the conditioning plant shown by, e.g., a glass frit packing, the same type of glass being used as that serving for waste vitrification. Adsorption on the glass powder surface reduces the content of radioactive elements in the exhaust gas to the ppm level.
