Patent DE-3118060-A1 (DE)
Title: Method and arrangement for monitoring a nominally gastight hollow body
Inventor: RICKER THOMAS DR RER NAT
IPC: G08B13/20
Filed: 1981-05-07
Abstract: According to the invention, the oxygen partial pressure in the cavity is kept very low, for example less than 10<-4>, as a result, for example, of filling with noble gas or evacuation, in hollow bodies which are to be monitored, for example multiple-pane insulating glass windows. Damage to the hollow body, for example glass breakage, results in a rise in the O2 in the insulating gas and this rise is detected by a component which is fitted in and/or on the hollow body and which contains an oxygen sensor (heater wire) and, if necessary, activates an alarm.
Patent DE-3120007-A1 (DE)
Title: Secondary combustion chamber for an internal combustion engine with at least one reciprocating piston and one main combustion chamber
Inventor: LATSCH REINHARD DIPL ING DR
IPC: F02B19/10
Filed: 1981-05-20
Abstract: An internal combustion engine has at least one main combustion chamber (7), a secondary combustion chamber (14) connected to the latter by way of a transfer port (16), which secondary chamber is of rotationally symmetrical design and a spark plug (17) projecting into one end of the secondary combustion chamber (14), with electrodes (22, 23) and an ignition chamber (26) enclosing these electrodes, which has at least one ignition chamber orifice (24, 25) opening into one end of the secondary combustion chamber (14). The transfer port (16) is arranged at the other end of the secondary combustion chamber (14) so that a fuel-air mixture flowing in from the main combustion chamber (7) strikes the spark plug (17) in the form of a jet. The jet is strongly deflected by the spark plug (17) within a zone, which is only slightly greater than the cross-section of the jet. As a result, very strong accelerations act on the mixture and a partial quantity of the fuel is expelled from the mixture against the spark plug (17) and penetrates into the spark plug (17). This partial quantity increases the ignitability of the mixture which reaches the electrodes (22, 23). <IMAGE>
Patent DE-3123224-A1 (DE)
Title: Electrically operable, hydraulic control valve
Inventor: WARNKE HANS-GUENTER
IPC: E21F9/00
Filed: 1981-06-11
Abstract: The electrically operable, hydraulic control valve is operated in the opening direction by an electric drive mechanism and in the closing direction by the hydraulic pressure medium flowing back. Use in fiery areas in underground mining makes it necessary to limit the electric power fed to the electric drive mechanism to 10 watts. To nevertheless be able to produce the requisite high power for opening the valve, the electric drive mechanism contains an energy accumulator, preferably in the form of a compression spring (9) which is preloaded by a tensioning mechanism (11, 15; 12, 16) driven by means of a low-power, electric geared motor (19). The tensioning mechanism (11, 15; 12, 16) abruptly releases the energy stored in the compression spring (9) to open the valve and then, to close the valve, clears the closing path for the closing body (4) of the valve by releasing an abutment (10) supporting the compression spring (9) for a displacement in the closing direction. <IMAGE>

Title: Flexible mount, in particular for supporting machines or machine parts
Inventor: MAIR CHRISTIAN DIPL ING
IPC: F16F13/22
Filed: 1981-06-26
Abstract: A flexible mount (1), in particular for supporting machines or machine parts, for example internal combustion engines or the like, is provided with a core (2) for the introduction of force, an abutment (3) for taking up the force, at least one spring element (6) arranged between the core (2) and the abutment (3), and at least one absorbing body (11) connected via at least one spring element (10) to the core (2). In order to avoid having first to pass through a resonant range in order to achieve an absorption effect and to obtain a mount which is as compact and simple as possible, the absorbing body (11) is suspended on the core (2) via the spring element (10) and the absorbing body (11) and/or the spring element (10) are coupled to the abutment (3) in a manner which allows transmission of motion counter to the direction of the introduction of force into the mount (1). <IMAGE>

Title: System for generating energy by means of water power
Inventor: DROEBER HELMUT
IPC: F03B13/26
Filed: 1981-07-22
Abstract: The invention relates to a system for generating energy by means of water flowing from a higher level to a lower level, which consists of a reservoir which holds water available above the lower level and has a blockable pressure line which originates at the floor of the container and pressurises a turbine, for example. In order, on the one hand, to render the system independent of the tide and, on the other hand, to achieve higher pressures upstream of the turbine, the reservoir, of which a plurality can be assigned to one turbine, is formed from two continuous containers which are arranged concentrically one above the other and of which the lower one has a substantially smaller diameter than the upper container. Pistons are assigned to the two containers and are connected to one another via a piston rod. The upper piston is constructed as a float, and the upper container has in the lower region at least one sealable opening, while the subregion, situated below the piston, of the lower container has at least one sealable balancing opening. One configuration can provide for ballast water to be added onto the upper piston, which is designed as a float/working piston combination and is provided with sealable balancing openings. <IMAGE>

Title: Process for producing foam elements for electrostatically endangered operations by means of cladding the element with a skin on the outer sides at risk
Inventor: STEINHOFF HORST W
IPC: E21F9/00
Filed: 1981-11-02
Abstract: According to Fig. 1 of the application, a foam element is produced which is intended in particular for electrostatically endangered operations and which is made suitable for unrestricted use in such operations by means of cladding the element with a skin on the outer sides at risk. This utilises the fact that such foam elements have in part penetrating cells, which are covered with a dispersion of polychloroprene in a pressure spraying process at a pressure level of at least 3 bar and at most 6 bar. In this process, the dispersion uses the outer pores and cell walls and penetrates partly into these. Subsequently, the foam element is subjected to evaporation in moving air at room temperature or else outside temperature in a conditioning channel. This is advantageously performed until a conductivity of at least 10<7> ohms is reached. <IMAGE>

Title: Shoe-wiping mat having a plurality of tearable, removable sheets of crepe paper in a magazine container
Inventor: STRAHL GERHARD
IPC: A47L23/26
Filed: 1982-02-01
Abstract: Magazine containers having a plurality of sheets of crepe paper placed one above the other as shoe-wiping mats, in homes, schools and other sectors. Shoe-wiping mats are usually produced for permanent use. Their actual purpose, cleaning dirt from the soles of shoes, is fulfilled only unsatisfactorily since they cannot remove wet dirt, for example, adequately from the soles of shoes. In contrast, the paper pad of this novel shoe-wiping mat absorbs the wet dirt reliably. After soiling of the top sheet, it is simply removed, thrown away, and the next sheet takes over the cleaning function. The magazine container consists of an unbreakable plastic container of a size of about 600 x 400 x 20 mm which is water-tight. The bottom surface, the underside of the magazine container, is provided with an anti-slip coating.
Patent DE-3207197-A1 (DE)
Title: Device for producing a spray jet
IPC: B05B1/02
Filed: 1982-02-27
Abstract: Devices for producing a spray jet generally have a nozzle head with a nozzle section and an inlet section connected upstream of the latter in the flow direction, via which section there is a connection to a feeder unit for the spraying agent. The equaliser which is connected upstream of the nozzle section, and which has at least one guide surface running parallel to the flow direction of the spraying agent, is held, in the known devices, outside the nozzle head at a relatively large distance from the nozzle section. In order to produce a more uniform and compact spray jet which atomizes to a smaller degree, the equaliser (7) is arranged in the inlet section (5). The resulting direct assignment of the equaliser to the nozzle section can be effected in particular by virtue of the fact that the outlet cross-section (7') of the equaliser (7) is at most at a distance (A) from the inlet cross-section (6') of the nozzle section (6) which is equal to 50% of its diameter (D). <IMAGE>

Title: Process for recovering mineral acid compounds free from radiation from mineral-acid ores containing, in complex form, uranium, thorium, titanium and rare earths
Inventor: KRISMER BRUNO DR
IPC: C22B3/26
Filed: 1982-03-26
Abstract: In a process for recovering earth metal acid compounds free from radiation from earth metal-acid ores containing, in complex and other forms, uranium, thorium and radium, the crushed ore is first subjected to a treatment, after which all the uranium is present in only one oxidation state in which it cannot transfer into the phase containing the earth metal acid compounds during digestion. For this purpose, the ore can be digested using sulphuric acid, uranium and thorium going into solution and the earth metal acid compounds remaining in the solid residue. In other potential methods, the ore is digested using hydrofluoric acid and a simultaneous reduction of the uranium to U(IV) occurs, so that niobium and tantalum go into solution, but uranium and thorium remain in the solid residue. The solid residue is further treated in the first case with hydrofluoric acid to recover Ta and Nb, and in the second case, if required, with sulphuric acid to recover U.
