Title: Hydraulic servo with safety valve - which blocks increase in output pressure after set level is reached irrespective of applied pressure
Inventor: STAISCH DIETHER
IPC: B60T13/16
Filed: 1973-09-20
Abstract: The hydraulic servo cylinder has a control valve and an activating rod guided in seals. A hydraulic pump supplies one side of the valve with the return flow passing through a variable restriction, to increase the servo pressure. The maximum setting of the pump can be exceeded if the pedal is pressed excessively, and can lead to servo damage. This is avoided by a pressure safety valve which blocks the restriction as well as blocking off the supply line from the pump. The servo output is then stabilised at its maximum setting, irrespective of the applied pedal pressure. The safety interlock is lifted if the pedal pressure is released.

Title: Natural gas calorimetry - by nuclear magnetic resonance of hydrogen atoms coupled with volumetric meter readings
Inventor: HOFMANN DIETER DR PHIL
IPC: G01R33/44
Filed: 1974-02-18
Abstract: The heat of combustion of natural gas can be measured by nuclear magnetic resonance. The molecularly fixed hydrogen is regarded as a measure for the heat of combustion and is found from the amplitude of the nuclear magnetic resonance signals of the protons. The heat content of the gas passing through a measuring station is recorded by coupling this with a volumetric meter. The periodic insertion of a reference substance in the moving coil of the measuring probe is used to form a digital quotient and to calibrate the instrument. The error introduced by higher hydrocarbons into the measurement is small (under 1%). In regional grids with less fluctuation in the gas compsn., suitable calibration can reduce the systematic errors to a few %s.

Title: Insulated building blocks of concrete - cast about a foam plastic core to ensure captive insulation without core damage
Inventor: MAGERLE OTTO ING
IPC: B28B19/00
Filed: 1975-05-20
Abstract: Building blocks made by casting a concrete casing about the top and sides of a prefabricated block of insulation material such as expanded polystyrene. The core block has dovetail recesses to key on the cast jacket. The block features projecting tongues which traverse the cast casing down the centre of the end faces of the block. Also described is a mould which can be lowered around a block placed on a vibrating platform to contain the concrete casing during casting, with or without deadweight loading of the cast slurr for consolidation. Used for mfr. of blocks offering good thermal and acoustic insulation due to the core and the bridges of absorbant material which butt between the ends of the adjacent blocks and thus interrupt the thermal bridges of the block casing at each end. Casting the concrete about the core causes less loss of damaged cores than systems requiring mechanical loading and anchoring of cores into prefabricated hard casings.
