Patent DE-3538531-A1 (DE)
Inventor: STEINIGER HANS PETER
IPC: B27N3/00
Filed: 1985-10-30
Abstract: 1. Method of continuously producing chip boards, fibre boards and like boards, with which a fleece formed on a support and consisting of lignocellulose and/or cellulose-containing chips, fibres and the like, mixed with at least one bonding agent, is pressed while being heated in a calander press with a heated pressurising drum embraced over a part of its circumference by a steel band running over guide rollers and pressurising rollers and is discharged in the form of a continuous length of board, the fleece being compressed at the leading end of the pressing gap and then being heated while enclosed between heated pressurising drums and steel band and while being simultaneously advanced and is brought to the necessary hardening temperature, an additional application of pressure being applied to the steel strip, at least at one further circumferential position of the heated pressurising drum and thus to the fleece, which is under the radial holding pressure of the steel band, and thereafter the fleece is cured to form a finally compressed length of board, characterised in that the additional application of pressure only takes place after a time when the particles are heated to a temperature at which they are fully transformed into their yieldable state, and which corresponds substantially to the final hardening temperature of the bonding agent being used.

Title: Electric toasting device for toasting slices of bread
Inventor: ROSSI GIUSEPPE DE
IPC: A21C9/08
Filed: 1986-01-08
Abstract: The invention relates to an electric toasting device for toasting slices of bread, having a toasting compartment with electric heating resistors and with an inlet passage and an outlet passage for the slices of bread, the compartment receiving the slices of bread to be toasted in each case in a single layer. The device additionally contains horizontal supporting and sliding means for the slices of bread, which pass through the toasting compartment, and a precisely time-controlled automatic feeding mechanism which performs to-and-fro horizontal displacing movements in order, each time, to introduce a single slice of bread into the toasting compartment through the inlet passage and push out the previously toasted, finished slice of bread through the outlet passage. This feeding mechanism removes the slices of bread to be toasted successively from a stack of slices of bread supported on the supporting and guiding elements in the immediate vicinity of the inlet passage into the toasting compartment. <IMAGE>

Title: Exhaust system for a multi cylinder internal combustion engine
Inventor: STAUDT HANS-PETER DIPL ING
IPC: F01N13/08
Filed: 1986-02-07
Abstract: In an exhaust system for a multi cylinder internal combustion engine the exhaust lines 11, 12, 13, 14 and 15 open into a common exhaust pipe in a succession corresponding to the firing order of the cylinders 1, 2, 3, 4 and 5. A directed swirl is thereby generated in the exhaust pipe, as a result of which the flow resistances are reduced and both a power increase and a reduction of the exhaust gas temperature are achieved. <IMAGE>

Title: Arrangement for the fluidic transmission of a force or a feed movement
Inventor: STOLL KURT DIPL ING
IPC: F15B7/00
Filed: 1986-02-26
Abstract: An arrangement is proposed for transmitting a force or a feed movement from a cylinder unit (12) via a flexible line (20) containing a fluid, in particular a hydraulic fluid, to a second cylinder unit (22). Here, an electric positioning device (10) is connected via an actuator (18, 19) to an adjustable member (14), acting on the fluid, of one of the cylinder units (12). The two cylinder units (12, 22) are preferably constructed as rodless, flexible working cylinders (13, 21) of bellows-like configuration, which together with the line (20) connecting them form a hermitically sealed unit. The variable to be transmitted can thus be transferred to virtually any location even in restricted space conditions. <IMAGE>

Title: Process for the preparation of 5-ethylidenebicyclo[2.2.1]hept-2-ene and 5-methylene-6-methylbicyclo[2.2.1]hept-2-ene
Inventor: DONIKE WILHELM DR
IPC: C07C2/50
Filed: 1986-05-23
Abstract: The invention relates to a process for the safer preparation of the compounds of (di)cyclopentadiene and 1,2-butadiene mentioned in the title. The danger of explosion of the reaction mixture due to ignition by external means is excluded by the carrying out of the process in the presence of a desensitising agent. This consists of a monoolefinically unsaturated C4- to C8-hydrocarbon or a mixture thereof and of a hydrocarbon from the group consisting of saturated C4- to C8-hydrocarbons, benzene, toluene and mixtures of these hydrocarbons. The process permits the preparation of the process product(s) in high yield, based on reacted 1,2-butadiene.

Inventor: NIEWISCH JOACHIM DR
IPC: G01F23/292
Filed: 1986-05-27
Abstract: The invention relates to a fibre-optic level sensor for liquids, in which a light source (4) is optically connected to one end of a first optical fibre (8) and an optoreceiver (6) is optically connected to one end of a second optical fibre (10) and the other ends of these optical fibres (8, 10) are optically coupled to one end of a third optical fibre (14), whose other end (16) is free.

Title: Wall disc for a tunnel
IPC: E02D29/055
Filed: 1986-07-10
Abstract: The invention relates to a wall disc for a tunnel situated in the zone of active excavation, in particular a road tunnel or tube tunnel, which is formed from a plurality of arches with a corrugated or trapezoidal profile which are preferably joined in a manner impervious to water in the longitudinal direction of the tunnel and whose vertical side parts consist of bulkhead (sheeting wall) profiles which are placed in previously produced slots and joined to one another by a catenary-shaped roof element and which are provided in the region of transition between tunnel structures of different types and/or tunnel cross-sections with a wall disc built in accordance with the resistance principle. In order to be able to do without the complicated and thus expensive construction of additional excavation pits and the production of the wall disc from reinforced concrete, the wall disc is constructed as a steel wall which can be inserted from a high working level and by means of which the bulkhead profiles of the side walls and the roof elements are joined directly in a force-closed fashion or can be welded, with the result that an elastic continuum (concertina principle) is maintained undisturbed as far as possible in the longitudinal direction of the tunnel, and only low forces are to be absorbed in the transverse direction of the tunnel in accordance with the resistance principle.

Title: Method for sampling test objects by means of a sensor arrangement and device for carrying out the method.
Inventor: PESSENHOFER WALTER DIPL ING
IPC: G01D3/028
Filed: 1986-12-12
Abstract: When sampling test objects by means of sensor arrangements which exhibit transmitting and associated receiving elements, the problem is that these arrangements are sensitive to ambient influences (external light in the case of light barriers). A method is demonstrated which largely eliminates these influences. Firstly the output value of the receiving element is sampled with an inactive transmitting element, this value is stored, then the transmitting element is activated, the temporarily stored value is subtracted from the output value of the transmitting element then present, this difference amount is provided as sample and then the next similar sampling cycle is begun.
