Title: Multistage refrigeration control system - connects compressors which have been idle longest, to comply with rising load
Inventor: HOENER WOLFGANG
IPC: G05D23/19
Filed: 1977-12-27
Abstract: The system controls the operation of compressors in a multi-stage refrigeration system, cutting individual ones in and out depending on requirements. As refrigeration demand rises, based on a set desired value of temp. or pressure, the compressors which have been standing idle for longest are cut in one after the other, while as it falls those which have been running longest are cut out one after the other. This is so arranged that each time a different compressor carries the base load and another one the peak load in successive periods.

Title: Multistage catalytic naphtha reforming process - without added or recycle hydrogen
Inventor: GREENWOOD ARTHUR RAYMOND
IPC: C10G35/12
Filed: 1978-01-16
Abstract: A multistage process for the reforming of naphtha feeds in the presence of a catalyst comprising a Gp. VIII noble metal on an alumina carrier to produce a gasoline fraction of increase octane number. Specifically, the feed is reacted, in the absence of added or recycled H2, in a plurality of reaction zones through all of which the catalyst particles flow downwardly via gravity flow. The feed is first reacted in the lowermost reaction zone from which deactivated catalyst particles are withdrawn for regeneration. The effluent from this zone is then reacted in the uppermost reaction zone into which fresh or regenerated catalyst particles are introduced, and then finally in one or more subsequent lower reaction zones. The product is recovered from the effluent of the reaction zone immediately above the lowermost zone. Compressive H2 recycle is eliminated and thus significant energy savings are obtd.

Patent DE-2812362-A1 (DE)
Inventor: WEHSNER GERHARD ING
IPC: H05K7/14
Filed: 1978-03-21
Abstract: The individual printed-circuit boards (1, 1', 1'') can pivot about a common horizontal rotation axis (4), which is located outside its overall volume, individually or in groups, and simultaneously or successively. They are held firmly, such that they can be fixed in their position, by means of a mounting part (5, 5') which is provided with comb-like recesses and can pivot about another rotation axis (6) which is parallel to the horizontal rotation axis, and are offset in a staggered manner laterally with respect to one another in order to guide the printed-circuit boards about their rotation axis. Allocated to each printed-circuit board are two tilting levers (3, 3', 3'') whose separation increases as the distance of the respective printed-circuit board from the rotation axis increases. In this case, all the parts of the assembly are advantageously accessible without removal from the stack. <IMAGE>

Title: Electronic moisture meter for tobacco - has capacitor sensor forming part of RC network coupled via oscillator to converter with compensating offset
Inventor: POSKITT WALTER EDWARD
IPC: G01R27/26
Filed: 1978-07-03
Abstract: the moisture detection unit, for sensing the moisture content of tobacco, comprises a capacitor sensor forming part of a C.R. network arranged so that the tobacco is passed through or near the sensor. The capacitance of the sensor is proportional to the moisture content of the tobacco, and determines the frequency derived by an oscillator to which the C.R. network is connected. The output frequency is inversely proportional to the sensor capacitance. A frequency to voltage converter derives a voltage proportional to the frequency and this voltage signal is then passed through an inverter. The inverter has an off-set which compensates for the standing capacitance of the sensor, to derive an output voltage which is proportional to the moisture content of the tobacco. The voltage can then be used to drive a digital read-out and control equipment associated with the tobacco water spraying.

Title: Accelerated pyrolysis of waste rubber, plastics, and refuse - by pre-heating the charge with effluent gases from indirect heating of pyrolysis reactor
Inventor: LEIKERT FRANZ
IPC: C10B53/00
Filed: 1978-08-11
Abstract: Worn-out tyres, plastics materials, scrap from power cables, and domestic and industrial refuse are pyrolysed. Pyrolyses is accelerated by subjecting the materials (which are to be de-gassed) to preheating by gaseous effluents. The preheating is achieved by indirectly heating the pyrolysis reactor. The pyrolysis gases formed act as heat transfer agents before leaving the pyrolysis reactor and so accelerated heat convection by gas circulation. There is improved heat transfer by convection from gas to materials.
