Title: Device for inputting, storing and processing documents
Inventor: STRAUCH WERNER
IPC: H04N1/028
Filed: 1985-05-04
Abstract: A device for inputting, storing and processing current, arbitrarily composed documents comprises a punctiform light source, e.g. in the form of an electron-beam tube or of a laser, with numerically controlled beam deflection in two mutually perpendicular coordinates, and a plate which consists of light-collecting material and has at least one light-emitting edge on which there is mounted an optical sensor as transmitter for a computer and the peripherals thereof. The grey tone of the document effects a coupling-out of a portion of the quantity of light fed to the light-collecting plate from the light source. The optical sensor for the light emerging from the light-collecting plate generates charge carriers upon incidence of light, the number of which carriers is proportional to the light intensity. The sensor delivers for the computer pulses which have been digitised in accordance with the grey tone gradation scanned at the document. Each arbitrary document is machine-readable and its information content can be stored, processed and thereafter made available again in an altered form. <IMAGE>

Patent DE-3539853-A1 (DE)
Inventor: WALZ RUEDIGER
IPC: F16B12/20
Filed: 1985-11-09
Abstract: A fitting for connecting two structural components. The fitting includes a locking device mounted on the first structural component and a support device mounted on the second structural component. A rotary member in the support device defines circumferentially extending conical surface against which the front end of the locking device is pressed when the two fitting devices are connected. The force exerted by the front end of the locking device causes the rotary member to be turned. The rotary member has a helical end face which is initially outside of the range of travel of the locking device. Upon turning of the rotary member, the helical end face comes into engagement with a countersurface of the locking device. The resulting connection can only be released by means of a tool. The structural components are pressed tightly together by a further turning of the rotary member. A piece of furniture composed of several structural components can be initially connected without the aid of a tool and can subsequently be tightened after the piece of furniture has been assembled. The fitting makes possible the connection of structural components where the tolerances in assembling the fitting devices are inaccurate or have been exceeded.

Title: Porous base for fluidised bed furnaces
Inventor: HERDIECKERHOFF RAINER
IPC: F27B15/02
Filed: 1985-12-09
Abstract: In a porous base 1 of ceramic material for the retort 2 of a fluidised bed furnace heated internally or externally, the working life of this base in the high temperature range has been increased by deviating from conventional forms of construction and using, as the ceramic material, a ceramic casting composition of low viscosity, which hardens in the course of the firing (baking) process, the composition being high temperature resistant after firing; the casting composition flows through (between) Styropor particles (spheres) or the like arranged as a layer in a mould and fills the interstices between these particles so that, after hardening and combustion of the particles, cavities which are, in all directions, interconnected and continuous are left, and the material thus constitutes a dividing wall which acts as a gas throttle (restrictor) and divides the retort 2 into a high pressure space and a low pressure space. For more advantageous assembly, the outer surfaces 3 are in part made gas-impermeable by sealing 4 with ceramic adhesives or the like. <IMAGE>

Title: Agent for desulphurising molten iron
Inventor: MEICHSNER WALTER
IPC: C21C1/02
Filed: 1985-12-17
Abstract: A finely granular agent for desulphurising molten iron consists of 50 to 98% by weight of industrial-grade calcium carbide and 50 to 2% by weight of a dried coal containing at least 15% by weight of volatile constituents. The coal is intended to liberate the volatile constituents, at the temperature of the iron melt, within less than 60 seconds, preferably less than 40 seconds, and in doing so to evolve a volume of gas of at least 80 l(S.T.P.)/kg of coal. Suitable coals for preparing the agent are lignite, bright-burning (open-burning) coal, gas-flame coal and gas coal (bituminous coal). The agent is prepared by adding the dried coal to the calcium carbide, which may have been pre-crushed, and comminuting the mixture to a particle size of 90% 200  mu m. Using a carrier gas, the agent according to the invention is blown, in a fluidised form, into the iron melt, using the conveying gas in an amount of 3-30 l(S.T.P.)/kg of agent, at a conveying rate (feed rate) of 10 to 100 kg/min.

Patent DE-3624419-A1 (DE)
Title: Apparatus for the monitoring of articles
IPC: B08B9/46
Filed: 1986-07-19
Abstract: To reduce disturbing influences (moisture inter alia) in apparatuses for the monitoring of articles, especially in packaging machines, the articles, with or without a constant spacing, are compared with a permanently set desired value at a point in the passage of the articles which all the articles pass, and, if there is a difference, are removed before they reach the point in the passage of the articles which no deviating articles pass. At a point in the passage of the articles which no deviating articles pass, the disturbing factors are determined by comparing the signals of the articles with signals of articles free of disturbing factors. When the disturbing factors exceed a specific value, the desired value is changed. Thus, there is no need for reference articles to be additionally introduced into or discharged from the passage of the articles. Because the monitoring point at which all the articles are recorded and the monitoring point at which no deviating articles are recorded are arranged in such a way that they are affected by the same disturbing influences, the disturbing influences cannot impair the result of the article comparison.
Patent DE-3631081-A1 (DE)
Title: Firing simulator for service personnel and sportsmen firing, target arrangement for a firing simulator, and a method for indicating the hit point of a light beam which is transmitted by a weapon mock-up of the firing simulator
Inventor: EICHHOLZ HELGE
IPC: F41J5/02
Filed: 1986-09-12
Abstract: The instruction and training times of service personnel and sportsmen firing on firing ranges with weapons and live ammunition are generally very short. Practice firing which is carried out by way of a substitute using practice ammunition for target practices provide no control of the firing performance of those firing. The firing simulator according to the invention creates a remedy for this. It consists of a weapon mock-up, in the case of which the barrel is replaced by a light source and focusing optics, and of an electronic target arrangement. The latter has a target with a plurality of indicating elements which are used for indicating the hit point of the light beams which are emitted from the light source of the weapon mock-up. The arrangement furthermore comprises a control circuit. Each of the indicating elements is associated with a specific location on the target and, for its part, consists of a photoreceptor and a photoemitter. When the lightbeam strikes one of the photoreceptors, the associated photoemitter is energised (excited) by the control circuit.
