Title: Liquid filtering device - with cylindrical metallic filter and axially movable inner impermeable cylinder
Inventor: ARNTZ HANS-JOACHIM
IPC: B01D25/38
Filed: 1978-03-17
Abstract: The Parent Patent described a filter for liqs. in which the cylinder walls and/or the bottom opposite to the open end consists of a thin metallic filter material with a permeability of 40-200 mesh. A hollow cylinder with an impermeable wall is introduced inside this cylinder to a variable depth, with a conicity at the introductory end.

Title: Sewage clarification system - combines aerobic and anaerobic treatment with efficient heat utilisation
Inventor: KNEER FRANZ XAVER
IPC: C02F3/28
Filed: 1978-04-05
Abstract: In a combined aerobic and anaerobic sewage treatment system, the sludge undergoes an anaerobic an anaerobic process in a cont-roll energy producer, i.e. a digestion chamber. This is followed by a bioreactor in which a controlled rotting process humifies and sanitises the sludge. The bioreactor supplies the heat required for the anaerobic treatment. The treatment ensures an optimum energy recovery at lower operating costs and in a process free from smells. It provides a better recycling of waste into the cyclic biological process.

Title: Improving bonding between hydraulic binders and mineral additives - by treatment of the binder with a peptising agent and addn. of a flocculating agent to ppte. the binder
Inventor: WUESTEFELD BERND DR
IPC: C04B20/10
Filed: 1978-05-19
Abstract: Process is claimed for improving the reciprocal action between (a) hydraulic binders such as alumina cement, with or without the addn. of metal phosphates, and (b) mineral additives. The particles of binder are first peptised by the addn. of a peptising agent to the mixt., and are then flocculated out onto the surface of the mineral additive by the addn. of a flocculating agent. The treatment conditions the surface of mineral additives such as glass fibres, rockwool, slag wool, perlite, pumice, vermiculite, kaolin wool, aluminium silicate fibres, etc. Addn. of hte peptising agent to the making-up water improves the dispersibility of mineral fibres, which thus requires less energy. The peptising treatment gives excellent reciprocal action between the binder and the additives, giving high strength building components, shaped parts. etc.

A second piston (8a) is symmetrically arranged and moves in opposite direction when pressurised.
Patent DE-2829884-A1 (DE)
Title: Locking device for emergency actuator of pipeline valve - operated by line pressure to depressurise actuator above given line pressure
Inventor: WITTMEYER HELMUT
IPC: F16K31/143
Filed: 1978-07-07
Abstract: The device is intended for an auxiliary or emergency actuator of a pipeline valve which is normally operated by means of the pressure in the line. The actuator is powered by a manual hydraulic pump via a manually operated (12b), normally spring-centered, control valve. The locking device is connected to the line and is so arranged that, above a given minimum line pressure, a spring-loaded locking element arrests the control valve in the mid-position, thus holding a pressure-less by-pass open so that the actuator does not prevent normal operation of the pipeline valve.

Title: AC=DC smoothing and rectification circuit - has smoothing capacitor connected to decoupling capacitor to derive AC low voltage supply from ripple in rectified DC supply
Inventor: MAURER FRANZ DIPL ING DR
IPC: H02M7/06

The assembler eliminates the need for spot welding of the two components.
Patent DE-2847193-A1 (DE)
Title: Coke oven gas dedusting - by tangential jets in ascension pipe causing swirling flow to deposit solid particles
Inventor: FACH HORST
IPC: C10B27/00
Filed: 1978-10-30
Abstract: Hot coke oven gas is dedusted as it passes through the ascension pipe by introducing at the base of the ascension pipe a gaseous medium in jets which are directed slightly upward and at an angle to the radius. The centrifugal force causes dust and ash to be thrown against the walls and to be trapped in the tar lining the upper part of the ascension pipe. This removes dust before the coke oven gas reaches the collecting main. The gaseous medium can be branched off the purified coke oven gas system.

Title: Controlling soil insects with organo:phosphorus derivs. - contg. 2-cyclopropyl-pyrimidyl gp.
Inventor: MAURER FRITZ DR
IPC: A01N57/08
Filed: 1979-12-20
Abstract: Compsn. for controlling soil insects contains as active ingredient a pyrimidine cpd. of formula (I), (X is oxygen or sulphur, R is alkyl, R1 is alkyl, alkoxy, alkylthio, alkylamino or phenyl. R2 is alkoxy, alkoxyalkyl or alkylthio- alkyl or when R1 is alkyl or phenyl, it can also be alkyl. R3 is H, alkyl or halo).

After a further 2-7 days, kill of the insects was 100%, compared with 0% kill for the cpd. with cyclopropyl replaced by isopropyl. (Ia) was also 100% effective at 10 ppm against Tenebrio molitor larvae.

Patent DE-3007629-A1 (DE)
Inventor: REIBER HANS ING GRAD
IPC: H02M7/529
Filed: 1980-02-29
Abstract: If a three-phase current is generated by dc-to-ac conversion, a higher ac output voltage is achieved by connecting each of the three phases alternately to one of the two terminals of the dc voltage source during a sixth-period section, while the two other phases have a sinusoidal waveform, such that the difference voltages between all three phases are sinusoidal.
Patent DE-3009624-A1 (DE)
Title: Electronic watch seal - against water and dust ingress consists of silicone oil filling
Inventor: PLAAS-LINK ANDREAS
IPC: G04B37/02
Filed: 1980-03-13
Abstract: Electric or electronic wristwatches are sealed by filling their cases with a transparent liquid which allows the liquid crystal or light emitting diode displays to be read. The liquid should be incompressible and have a low temperature coefficient to make it insensitive to ambient pressure and temperature fluctuations. It should also have a high electrical resistivity, and it should be hydrophobic. The watch case should be of a material which allows slight elastic deformation. More specifically the liquid which satisfies all these demands is silicone oil. It creates a reliable protection against the ingress of water or dust and a quick pressure compensation.
Patent DE-3013020-A1 (DE)
Title: Cooling thermoplastic extrusions - material passes through tube with alternately vacuum holes and water-cooling grooves to minimise friction
Inventor: MUELLER ALFRED
IPC: B29C48/90
Filed: 1980-04-03
Abstract: Thermoplastic extrusions are cooled by using a cooled tube of the ultimately required cross-section which has a number of holes in its bore wall connected to a vacuum source. The bore wall has a series of cross-grooves at intervals, each supplied with coolant. The hot extrusion flows through a tube which has circumferential holes connected to a vacuum and alternating with grooves supplied with water coolant. The holes and grooves are set at intervals of 20-50 mm. Coolant flows in through the top bore and out from a similar bore in the bottom half; similarly vacuum is applied via a bore to produce the desired cross-section of extrusion. The cooling water provides a surface film on the extrusion and thus reduces frictional resistance to its flow; the edges of the grooves are rounded to assist this effect. Highly efficient cooling, minimal frictional resistance.
