Title: High-grade combustible gas prodn - by compressing hot feed gas, superheated steam and a carbon cpd at high temp
Inventor: BAENTSCH ERICH
IPC: C01B3/34
Filed: 1974-01-10
Abstract: High-grade combustible gas is produced in a compressor by introducing a hot feed gas (e.g. lean gas, water gas, gas from low-temp. coal carbonisation, town gas or a waste gas with a high CO2 content) and superheated steam into the compressor by suction or injection, injecting a carbon cpd. as a liq. spray or gas, compressing the mixt. at high temp., and thus converting the mixt. into a combustible gas (contg. CH4 and higher hydrocarbons). The compressor should have controlled inlet and outlet valves and as little dead space as possible. It is suitably an engine cylinder operated by means of a diesel engine; in this case, the exhaust gases from the diesel engine can be injected together with superheated steam (from an external source) and lignite-tar oil into the compressor. The system is space-saving and accurately controllable, giving a product gas of constant quality.

Title: Support elements for laying paving slabs - comprise cellular deformable bodies which may be filled out with a non-deformable casting compsn.
Inventor: MISCHLER HELMUT
IPC: E04D11/00
Filed: 1974-01-14
Abstract: Paving slabs, e.g. for the paving of terrasses, are laid with their corners resting on supporting elements which comprise deformable cavitied bodies. The space between the bodies may be filled by casting with a mass that is not deformed by stresses exerted on the slabs. The deformable bodies may be circular or polygonal rings. Slabs laid on the supports about level even though there may be slight differences of thickness of the individual adjacent slabs. Laying is relatively simple. The slabs can be laid closely together, without undesirable gaps as is common with prior-art adjustable supports. The deformable body may be of barely elastic or non-elastic (in)org. foam material e.g. a PF foam. Suitable apparent density is 0.05 g/cc. The casting mass for filling the space may be concrete, mortar, filled plastics or silicone rubber.

Title: Automatic engine speed regulating selector - has tachometer needle giving photo electric signals selected to limit fuel supply rate
Inventor: KRUMMEL HEINZ
IPC: B60K31/18

Title: Foam mattress with visually-controlled degrees of hardness - has two foam parts of different length engaging in displaceable saw-tooth manner
Inventor: LENZ GEB KAISER KAROLINE
IPC: A47C27/15
Filed: 1974-02-05
Abstract: The mattress which can be used for a seat or bed is made of foam material and designed to be infinitely adjusted as regards its hardness. The two superposed foam mattress parts are of different lengths so that the underside of the upper mattress part engages in saw-tooth fashion in the suitably shaped upper side of the lower mattress part. These two mattress parts are secured to frames so that they can be displaced relative to each other with the result that the overall height and thus the degree of hardness of the mattress can be infinitely adjusted. The tips of the saw teeth of the lower mattress part are truncated to provide air ducts which increase when the lower mattress is displaced thereby reducing the hardness of the surface. A visual control device is provided for altering the hardness by displacing the mattress frame.

Title: Engaged indicator cct. for telephone exchanges - has memory elements for each line all being scanned cyclically
Inventor: RIEDMANN GUENTER
IPC: H04Q3/62
Filed: 1974-02-21
Abstract: The engaged-line indicator circuit, for telephone exchanges, has the separate terminal lines coupled to sampling points and sampled cyclically. A pulse signal is generated when a line is found to be engaged and this signal triggers a pulse sequence which is passed to selection circuitry with marker generator. Each line has its own memory element. When the signal pulse from any line coincides with the marker signal from the selection circuitry, a gating circuit passes into its 'store' position. This gating circuit is reset to its 'output' position by a reset pulse generated by the selection circuitry at the beginning of each group-marking.
