Patent DE-3104940-A1 (DE)
Title: Roof-support system for mines
Inventor: RADMALL PAUL
IPC: E21D23/16
Filed: 1981-02-11
Abstract: The invention relates to a roof-support system for a mine, in which the roof girder is kept in contact with the roof during the advance of the support in the direction of a conveyor by the props of the support being connected to a low-pressure fluid pipe which has a small bore. In order to prevent the build-up of a back pressure in the pipe which interferes with the advance of the support if the roof and the floor approach one another, a pressure-actuated valve is provided in the low-pressure-fluid supply circuit of the props. This valve normally connects the props to the low-pressure pipe. If a back pressure builds up in the props, this back pressure displaces the valve so that the props are connected to the normal return line until the pressure is removed, after which the valve moves into its normal position. <IMAGE>

Title: Device for influencing the quantity of fuel fed to an internal combustion engine
Inventor: SEMMLER FRANZ
IPC: F02D9/02
Filed: 1981-08-14
Abstract: The invention relates to a device for influencing the quantity of fuel fed to an internal combustion engine, preferably of a motor truck, to at least make it easier for the driver to keep to an optimum engine speed range. For this purpose a load device acting on the adjusting device is provided, which is connected to this adjusting device by way of an actuator so that a clearly discernible resistance is obtained to an adjustment in the direction of an increased fuel quantity once the optimum speed range of the engine in question is left. The driver is not restricted to this optimum speed range so that, if necessary, he or she may also pass into the higher engine speed range.

Patent DE-3210008-A1 (DE)
Title: Pneumatic brake device for rail vehicles
Inventor: SKACH KUNO DIPL ING
IPC: B60T15/24
Filed: 1982-03-19
Abstract: The pneumatic brake device for rail vehicles, especially rail locomotives, has a three-pressure brake control valve (5) with a main air line chamber (4) and a reference pressure chamber (7). In the connection from the main air line (1) to the main air line chamber (4) a shut-off valve (3) is incorporated, which can be arbitrarily closed only below a pressure level in the main air line (1) corresponding to full braking. Into a connection of large cross-section, provided in addition to a usual filling device for the reference pressure chamber (7), between the  main air line chamber (4) and the reference pressure chamber (7) an arbitrarily operatable shut-off valve (22) and an overflow valve (20) are inserted in series, the overflow valve (20) closing in the event of the pressure in the reference pressure chamber falling below a certain pressure limit of, for example, 2 bar. A further, arbitrarily operatable shut-off valve (17) monitors a flow cross-section enlargement of the release nozzle (13) of the three- pressure brake control valve (5). By corresponding actuation of the shut-off valves a normal, conventional operation of the pneumatic brake device, a post-braking valve action, an adjustment in the event of an overloaded reference pressure chamber (7) and an arbitrary brake release in the event of emergency or forced braking are possible. At the same time any leaking of the shut-off valves cannot cause failure of the pneumatic brake device. <IMAGE>

In this design and arrangement of the air vessel, the flow medium passes through the vessel in a straight line. Preferably, the tubular membrane is a double tube, so that the flow medium cannot come into contact with the reservoir fluid for the pressure vessel. <IMAGE>

Title: Diaphragm displacement pump
Inventor: NAEGEL HEINZ M
IPC: F04B43/107
Filed: 1982-03-20
Abstract: In the diaphragm displacement pump a hydraulic medium is pumped between an inlet valve arranged in a housing and an outlet valve in a chamber at higher pressure, which is performed by means of a driven piston. The diaphragm comprises a double hose (8), on which the individual hoses (9, 10) lying concentrically with one another are connected by a fluid lying between the hoses. The cylindrical intermediate chamber (11) is  connected by a line to a hose rupture display device (15), which has a pressure vessel (16) with a non-return valve (17) and a probe (18). The cylindrical intermediate chamber (11) between the hoses (9, 10) is preferably formed by spacing elements on that surface of each hose facing the other hose. The two individual hoses act like a single hose and there is a need only for a simple mechanical measuring element. <IMAGE>

Patent DE-3212151-A1 (DE)
Title: Apparatus for laying sheet-like building elements
IPC: E04G21/16
Filed: 1982-04-01
Abstract: The invention relates to an apparatus for laying sheet-like building elements for structures, such as roofing slabs, duct coverings, and wall elements or the like. Up until now, such laying operations have been performed by a number of workers, in each case according to the weight and size of the building elements to be handled, in a time-consuming, complex and accident-prone manner by means of a crane or the like, scaffolding being required for the most part. This is remedied by an apparatus which is characterised by an assembly apparatus which can be displaced by means of a running gear on the running surfaces, present on the structure, of the roof frames or the like, and which is designed with devices for receiving and positioning the sheet-like building elements to be laid. The assembly apparatus is essentially designed with a horizontal base frame with a supporting frame arranged perpendicularly thereon on which the running-gear units of the trolley rail, on which the trolley runs, can be displaced. Work is further facilitated by attachable appliances. <IMAGE>

Title: Blood flow measuring device
Inventor: ARMONIES GERHARD DIPL ING
IPC: A61B5/00
Filed: 1982-05-07
Abstract: The invention relates to the method and to the production of blood flow measuring devices. Known inventions are incapable of pressing the measuring head of the measuring system onto moving skin surfaces with a specific, constant, variably adjustable force F1 acting via a path. The blood flow measuring device according to the invention is capable of guaranteeing the above-described measurement conditions and thus permits for the first time the carrying out of measurements with sufficient accuracy. This is achieved, for example, by the simple arrangement of a direct current servo motor (1) which, via a pinion (2) moves a toothed rack (3), mounted by the ball bearings (7). A linkage (6) holding the measuring head (5) and pressing it against the skin surface as a function of the tension U1 is located on the toothed rack (3). The measuring head (5) comprises, for example, an NTC thermistor and is supplied by the voltage U2. From the transition function of the NTC thermistor resistance as a function of time, from the tension U2 and the contact pressure as well as a few blood flow parameters it is then possible to draw conclusions about the blood flow. This can be done simultaneously with the measurement or later, for example, with a microprocessor. <IMAGE>

Patent DE-3237418-A1 (DE)
Title: Flush-mounted installation box
Inventor: GRUBER WALTER
IPC: E03C1/02
Filed: 1982-10-08
Abstract: A flush-mounted installation box for sanitary fittings is described, which consists of a main part to be inserted into a wall installation recess and containing a base body, and of a cover which seals said main part. The cover possesses a bulge, the area of which is smaller than the entire area of the cover. During the interior finishing work on the building in which the installation box is fitted, the tiling of the room is laid partially over the cover so that only the cover bulge protrudes outwards. The cover, which hermetically seals the interior space of the installation box, can therefore not be removed, since the fastening means lie under the tiling. In addition, the installation aperture can be kept smaller, which is desirable for visual reasons. For the final mounting of the individually desired sanitary fittings, the cover bulge is sawn off along the outer face of the tiling in the last phase of the interior finishing work on the building. <IMAGE>
