Title: Process for hardening of cold-hardening mould material mixtures in foundries
Inventor: AHRENBERG KURT
IPC: B22C9/12
Filed: 1981-09-04

Title: Damped non-return valve
Inventor: NITSCHE KLAUS ING GRAD
IPC: F16K15/02
Filed: 1981-10-24
Abstract: In a damped non-return valve (10), a valve closing body (14) is guided in a guide cylinder (23). A cylindrical space (24), which is open to the exterior only through a damping opening (31), is closed by the guide cylinder (23), its base (22) and the valve closing body (14). The damping behaviour of the valve closing body (14), which is possibly oscillating, is fixed by predetermining the size of the damping opening (31). The valve (10) can be constructed such that it has a screw head (19) and an external threaded part (20) adjacent thereto, by means of which it can be screwed into the cover of a compressed gas tank such that it is protected against damage. Such damped non-return valves are used particularly advantageously in medical technology and other ventilation technologies, where smooth operation of the pressure-generating apparatus parts is required, such as in the ventilation of computers. <IMAGE>

Title: Preparation of pure sorbic acid having a desired particle size spectrum
Inventor: NEU HERMANN DR
IPC: C07C57/10
Filed: 1981-10-30
Abstract: According to the invention, sorbic acid is rapidly dissolved or partly dissolved/partly emulsified in water under superatmospheric pressure at a maximum temperature of 105 to 150 DEG C. If the maximum temperature was above 115 DEG C, the mixture is first cooled to 110 to 115 DEG C over a period of at most 40 minutes with stirring. The sorbic acid is then allowed to precipitate by further cooling with stirring, the cooling and stirring rate being selected in accordance with the desired particle size spectrum. However, if the maximum temperature selected was 105 to 115 DEG C, cooling from the maximum temperature to 110 to 115 DEG C is omitted, and the rest of the procedure is as already described.

Title: Position-finding system in waterways
Inventor: FAHRENTHOLZ SIEGFRIED R J DIPL
IPC: G01S17/875
Filed: 1983-02-15
Abstract: The invention is shown in Figure 1. On a waterway which is equipped on both sides with reflectors, a ship is travelling which is provided with a rotating pulse-radiation transmitting/receiving device, the angular position of which with respect to the ship's axis can be electronically interrogated by an angle measuring device and supplied to a computer. Whenever the radiation impinges on a reflector, the angular position is forwarded to the computer, which determines from this the location and the course of the ship. If not enough reflectors are available, then the distance from the individual reflectors can be additionally utilised for the evaluation. <IMAGE>
Patent DE-3305464-A1 (DE)
Title: Control device for opening and closing a door
Inventor: REJC GABRJIEL
IPC: E05F15/73
Filed: 1983-02-17
Abstract: An inductive control device for opening and closing a door comprises two induction loops which are laid in the door bottom and which are so offset relative to one another perpendicularly to the door plane that, in one direction of travel, the loop surface of one induction loop is first entered on one side of the door plane, whilst, in the opposite direction of travel, the loop surface of the other induction loop is first entered on the other side of the door plane. When one of the two induction loops is entered, the evaluation of the output signal of the other induction loop is blocked. The optimum moment of opening and closing of the door can thereby be suitably fixed for each of the two directions of travel.
Patent DE-3309951-A1 (DE)
Title: Optoelectronic strainometer
Inventor: KNAPP JUERGEN DIPL ING
IPC: G01B11/16
Filed: 1983-03-19
Abstract: The invention relates to an optoelectronic strainometer for contactless measurement of strains by means of optical scanning of two rosettes provided on the measurement object. According to the main claim, the rosettes are projected onto the ends of two optical fibre bundles. The fibres of each bundle form a four-phase reference rosette in accordance with Fig. 2 and are consequently combined at the opposite end to form 4 partial bundles to which a photoreceiver is connected in each case. It is possible with the aid of an arc-tan function to calculate the displacement of the rosette from the signals of the photoreceiver. The strain can be calculated from the difference in the displacements of two rosettes. The subclaims relate to   - an arrangement of two strainometers for computational compensation of changes in length, - equipping the strainometer with a zoom lens and a frosted-glass pane having gratings as an aid for adjustments,   - the use of rosettes for multi-axis strain measurement.   There is the advantage of the high resolution despite coarse rosettes, which favours the production of the rosettes and their applicability for extreme environmental conditions. <IMAGE>

Filed: 1983-07-01
Abstract: The invention relates to a decay tank (26) for accommodating radioactively contaminated waste liquid, there being present in the decay tank (26) an underpressure pi by means of which the waste liquid can be sucked into the decay tank (26). In order for the decay tank (26) not to have to be accommodated in specially equipped rooms, without the risk of the environment being exposed to danger due to leakage, for example, the decay tank (26) is constructed with two walls, a pressure pz prevailing in the interspace (32) formed between the walls (28, 30) which is smaller than the underpressure pi prevailing in the interior (34) of the decay tank (26). Furthermore, pressure equalisation can take place between the tank interior (34) and the interspace (32) when the pressure pz is higher than the pressure pi. <IMAGE>

Title: Process and apparatus for drying combustible solids
Inventor: HINTERKEUSER JAKOB DIPL ING
IPC: C10B57/10
Filed: 1983-07-06
Abstract: Hitherto, special inert gas producers, e.g. combustion chambers, have been provided for the maintenance of an inertised gas atmosphere in a drying apparatus for drying combustible solids, especially for drying coal. The danger exists here that, especially when the combustion space of the combustion chambers is aerated, detonation or even a gas explosion can occur in the system, leading not only to a disturbance of operation but also to possible damage to the combustion chamber or the drying apparatus. According to the invention, however, these disadvantages are prevented in that the combustion chamber (1), especially before being placed in operation, is evacuated and filled with inertising gas. <IMAGE>

Filed: 1983-09-12
Abstract: The invention relates to a hose-rupture safety device with a leakage-gas test device in the form of a hose connection piece, in particular for equipment attached to liquid-gas bottles by means of a hose, essentially consisting of a valve which prevents the gas from flowing out if the hose falls off or becomes leaky and in which an axially movable closing body closes a central discharge opening if the discharge counterpressure diminishes or does not appear and is held in the open position in the operating state by means of spring force, a piston being provided for lifting the closing body from the discharge opening, which piston can be actuated by means of push-button against spring pressure and, when the push-button is actuated, clears a bypass route which connects the gas spaces to one another in front of and behind the discharge opening. According to the invention, the hose-rupture safety device is designed in such a way that a leakage-gas test can be carried out simply, since it is effected semi-automatically and an indication is given as to whether there is a leak or not.

Title: Ventilator roof for vehicles
Inventor: DAVID WERNER ING GRAD
IPC: B60J7/16
Filed: 1983-10-19
Abstract: A ventilator roof with plug-in hinges for vehicles is proposed, the frame which receives the plug-in hinges being arranged within the perpendicular projection of the roof opening and the centre of rotation of the cover of the ventilator roof being located in the region of the front edge of the cover. By means of these measures, it is ensured that a fully automatic insertion of the complete ventilator roof unit is possible and when the ventilator roof is employed a static pressure edge which negatively influences the disturbance is not produced. Preferably, the frame forms a guide face which fixes the cover in the longitudinal direction of the vehicle so that the plug-in hinge can be of a correspondingly short design and does not have to engage behind the roof opening.
