Patent DE-2358775-A1 (DE)
Title: Clamp protection against removal through liquid concrete pressure - as support supplied from front through jaw recess closed by plug
Inventor: BAAL JOHANNES VAN
IPC: E04C5/16
Filed: 1973-11-26
Abstract: The support structure for the clamp members incorporates protection against their removal as a consequence of pressure from concrete in a fluid state, during the concreting process, which would affect the accuracy of the inlaid reinforcement, taking account of pressures emanating from below. Supply is effected from the front through the jaw-shaped recess, on a sloping mounting, and this is closed by a nail or wedge-type plug, and effective only in connection with nail holes or slits at the sides, giving the effect of a hole set in the middle of the support structure. This can serve as mounting for support bars of various diameters without laborious threading in from the side.

Title: Tandem cylinder and piston metering system - has adjuster piston and sealing piston which cooperate to control metering spindle adjustment throughout
Inventor: SCHMITT FRIEDRICH WILHELM
IPC: G01F11/04
Filed: 1973-12-11
Abstract: The infinitely adjustable tandem cylinder arrangement is for precise metering of fluids and has a hydraulically operated adjuster piston which is controlled by the fluid being metered and is without external mechanical parts of any kind. The fluid entering the filling space in response to this piston movement displaces the sealing piston within the fill space and switches over the attendant inlet and outlet valves in the metering circuit. The adjuster piston which initiates the metering action should be adjustable in stroke by means of a fitted spindle, thus providing differential metering to suit the duty or container capacity, ratios. This adjustment can be achieved whilst the circuit is operating.

Title: Eccentric rotor type compressor - has high coefficient of friction between rotor and shaft to maintain rotor contact
Inventor: STUMPE WENRER
IPC: F04C18/356
Filed: 1975-03-05
Abstract: The compressor has a cylindrical stator (1) through which the cranked section of a crankshaft (4) runs. The crank carries a rotor n5) which supports an outer ring (3) on ball bearings (6). A sliding vane (7) in the stator makes a seal on the rotor which also touches the stator at one point to make a second seal thus dividing the cylinder volume into two variable volume spaces. The surfaces of the crank and the bore of the rotor are machined to give a high coefficient of friction between them. The force resisting rotation of the rotor on the crank is thus sufficient to prevent the rotor turning to lose contact with the stator surface just before the rotor reaches top dead centre.

Title: Precise measurement of physical quantities - s by simultaneous use of several reading devices and arithmetic mean unit to avoid time variations
Inventor: FISCHER HANS WERNER DR
IPC: G01D1/02
Filed: 1975-06-12
Abstract: A precise method of determining the value of a physical quantity by making several measurements avoids errors inherent in the time intervals between measurements of current methods. Simultaneous measurements are made by several reading elements and a mean value of their results is produced. A further refinement consists of taking two sets of simultaneous measurements separated by a time interval determined by the longest correlation time of the reading elements. An arithmetic mean is then produced from both sets of readings. Improved speed and accuracy calls for an increase in the number of measurement devices, but in some systems these are already provided for reliability, in which case some would be redundant.
