Title: Method and device for measuring a pressure, particularly of a fluid
Inventor: HAEFNER HANS W DIPL ING
IPC: G01L7/16
Filed: 1981-11-05
Abstract: In a method of measuring a pressure, in particular of the stationary or virtually stationary pressure of a fluid, with a pressure-loaded measuring piston which is guided in a cylinder and is connected to a load-measuring device, it is proposed that the piston be guided without contact in the cylinder by means of hydrostatic or pneumatic lubrication by a separating fluid which is supplied under pressure and has a higher pressure than the fluid to be measured, in which arrangement the fluid producing the pressure is used as the separating fluid and is increased in pressure before being directed into the cylinder, or another fluid, such as, for example, a liquid or a gas is used as the separating fluid. The method is preferably used in the gravimetric analysis of the quantity of mineral-oil product in a fixed tank, preferably in a large tank. A corresponding device with a measuring piston guided in a vertical cylinder provides for pockets for the build-up of hydrostatic or pneumatic lubrication by a separating fluid to be provided in the wall of piston or cylinder and to be connected to a fluid-supply system, and for the piston to be supported via a supporting element on a measurement transducer.

Patent DE-3215239-A1 (DE)
Title: Arrangement for measuring relative speed
Inventor: BARNARD RICHARD HARRY
IPC: G01P5/01
Filed: 1982-04-23
Abstract: The invention relates to an arrangement for measuring the relative speed between a body and a flowing medium surrounding said body. An elongated body (1) extends as an obstacle in a tube (12), through which a flowing medium flows, and has a head part which is constructed in the shape of an arrow, points with its tip against the direction of flow and forms vortices in the direction of flow. The angle ( alpha ) between the two guide surfaces (2) on the head part of the arrow is not less than 90 DEG  and preferably lies in the range between 100 DEG  and 110 DEG . A sensor (not represented) for sensing the vortices is arranged behind the arrowhead in the flow direction, for example in the tail part of the body (1), and thus senses the vortices which alternately arise on the lateral surfaces (3) of the body (1). The output signals of the sensor are proportional to the relative speed between the elongated body (1) and the flowing medium. The arrangement can be used as a flowmeter for a flowing medium, or as a ship's log. <IMAGE>

Patent DE-3247975-A1 (DE)
Title: Method and device for detecting leaks in walls
Inventor: MENNENGA HERMANN
IPC: G01M3/20
Filed: 1982-12-24
Abstract: Test gas passing through leaks is conducted to the output side of a turbomolecular pump (1), advances against the pumping direction ("countercurrent pump") thereof to the input side and is detected by a detector (2) connected to said pump. Heavier gases (air), which disturb the detection and for which the pump (1) has a substantially higher compressive power are, by contrast, largely held back by the detector. To date, the partial pressure of the test gas in the detector or the signal output by the latter have been taken as a measure of the test gas current passing through a leak, but in accordance with the invention the speed of the countercurrent pump (1) is changed until the detector signal has a predetermined magnitude. A device (14, 4) for setting the speed is therefore provided in the device according to the invention. A high accuracy of detection is thereby achieved for an outlay which is smaller than before. <IMAGE>

This has been achieved by the upper flap and the lower flap being mounted on a removable supporting element via hinges. The supporting element is seated in pockets which absorb the pressure of the goods being transported. The supporting element is at the same time constructed as a hinge element. The lower flap is additionally held in the folded-out position via hooks.
Patent DE-3304844-A1 (DE)
Title: File for removal of hard skin
Inventor: BERGER MARGARETA
IPC: A45D29/04
Filed: 1983-02-12
Abstract: The file is intended for removal of hard layers on the human foot. Emphasis is placed on the allround application of abrasive paper on a relatively large compact body having overall dimensions of 35/4/1.5 centimetres. This special shaping permits comfortable, pleasant, quick and efficient removal of all hard layers. The negative experiences found with previous methods are thereby largely eliminated. The abrasive paper can be individually selected, is easy to change and is protected against slipping by a ring, cap and rail. Noteworthy are two large abrasive areas and a small one expediently having rounded longitudinal edges, so that critical points can easily be reached. The abrasive paper is economical and can be used for a relatively long time. A self-test for one year revealed these positive facts. An even longer handle is very valuable for users with restricted mobility, the troublesome visit to a chiropodist is often superfluous, and it is also possible to file toe-nails. <IMAGE>

Abstract: The device is equipped with a drawing cushion serving as a support for the blank holder and consisting of a plurality of hydraulically acting working cylinders and with a further drawing cushion for supporting at least one drawing punch movably guided in the drawing direction and consisting of at least one working cylinder. The working cylinder for supporting the drawing punch is in fluid connection with the working cylinders of the drawing cushion for supporting the blank holder and is supplied with the fluid pressure means displaced from the latter during the drawing operation. This actuates the drawing punch counter to the direction of movement of the blank holder, the drawing depth thus being the sum of a part-stroke of a drawing ring of the upper part of the tool, the said drawing ring moving downwards during the drawing operation, and of a part-stroke of the upward-moving drawing punch. A pressure sensor adjustable to a predetermined fluid pressure is arranged between the working cylinders of the two drawing cushions, the said working cylinders being in fluid connection, and is coupled to a signal transmitter which emits a signal which interrupts the drawing operation and, if required, reverses a drawing press when the set fluid pressure is exceeded. The pressure sensor can be set in dependence on the data of the drawn sheets used such that the drawing operation is interrupted at a fluid pressure lying at the tear limit of the drawn parts, with the result that before further drawing a ...

Patent DE-3339986-A1 (DE)
Title: Floor heating system
Inventor: DRUM GERD ING GRAD
IPC: F24D3/14
Filed: 1983-11-04
Abstract: In order to obtain an essentially constant surface temperature of the floor beyond the length of the heating pipe inlaid in the floor in a floor heating system, the heat transfer from the feed to the return increases gradually or stepwise, or the heat transfer resistance above the heating pipe decreases gradually or stepwise from the feed to the return. This is effected when the distance between the pipe and the floor surface is larger in the region of the feed than in the region of the return, or when in the region of the feed an additional heat barrier layer is fitted on the upper side of the pipe. The heat barrier layer is bonded by means of a hand device to the upper side of the pipe. Spacers of different heights are used to set the different height levels of the pipe sections in the floor.
