Title: Salts recovery from textile finishing effluents - integrated installation utilises vaporising heat in exchangers, recycles condensate into process
Inventor: KOEPPL FRANZ DIPL ING
IPC: B01D1/00
Filed: 1975-04-02
Abstract: Salts are recovered from the effluents of textile finishing and related processes, such as papermaking, carpet and artificial leather production, with the simultaneous utilisation of steam as well as of condensates for heat economisers working at >100 degrees C; by heating effluents having a total salts content of >0.5 kg/M3, before they are fed to the vapourisers of a single or multi-stage installation; directly to their boiling point, under a pressure which ensures that steam corresponding to the requirements of the heat consuming units, results. The effluents in the installation are continuously vapourised whilst increasing the volume to 1:1000, without salts being precipitated. After each vaporising stage, the pressurised steam is treated so as to separate the remaining salt-containing scum, and the energy of the cleansed steam is transferred to the heat utilising elements. The clean condensate is recycled as feed water, whilst the salt liquor remaining after vapourisation, is fed through burners for the destruction of its organic constituents, and the vaporising of the rest of the water, possibly with associated heat recovery; and the salts are obtained in the dry state. Not only are salts recovered from the effluents, but also, the energy used for vaporising can be utilised without loss, whilst a clean condensate can be recycled as feed water.

Title: Liquid gas vaporiser and heater - has waste heat from heat engine extracted through water production system
Inventor: EHLERT JOACHIM DIPL ING
IPC: C02F1/16
Filed: 1975-05-10
Abstract: The systems for vaporising and heating of a liquid gas uses the waste heat generated by a powered heat engine with an interposed drinking water extraction system of the vaporisation type in order to evaporate the liquid gas. The waste heat produced by, say, a gas turbine may be used by extracting the heat in the turbine discharge system by means of a drinking water extraction process wuch as may be applied to fresh water production from sea or brackish waters. In this way, industrial liquid effluent can be used as a heat source and as a raw water supply after cleaning.
Patent DE-2522634-A1 (DE)
Title: Wire hose cross cut machine - has cutter signal activated when feed material length and measured length coincide
Inventor: KUEHNI PETER DIPL ING
IPC: B23D33/00
Filed: 1975-05-22
Abstract: A motor driven transport roller advances material between it and a counter-pressure roller for a subsequent cutting device. A measurement unit controls the length of material feed with a feed devices set for determined cut-off lengths and a signal transmitter. The transmitter, when the fed cut-off length coincides with the measured feed length, gives a signal for the cutting process to take place. On receipt of the coincidence signal, a motor control reduces the motor speed almost to stop. The adjustable time circuit switches the motor back on at its original speed after a determined interval. To activate the material feed length measurement unit, an impulse frequency proportional to the speed of the transport feed roller is fed to it.

Title: D:A converter controlled from computer digital memory - by periodic set pulses and delayed reset pulses with delay time proportional to weighting
Inventor: VALOSEK PETR DIPL ING
IPC: H03M1/00
Filed: 1975-12-09
Abstract: The D/A converter is set periodically by a series of set pulses corresponding to the number weighting code and reset by reset pulses following the set pulses and with a delay time proportional to the weighting of the individual set pulses. A number of D/A converters with different addresses can be controlled by a composite code time multiplexed to the converters and containing the set pulses. The converter contains a binary memory and the set-pulse gating circuit is connected to the memory. The advantage lies in using a memory of drum or disc form of a digital computer to control the converter directly.

Title: Longitudinal cracks detection system - passes AC through steel wires and thin steel rods generating stray magnetic fields at cracks
Inventor: BOEHM KLAUS
IPC: G01N27/82
Filed: 1975-12-23
Abstract: AC is passed through the tested workpiece, so that a magnetisation is produced at the faulty places, generating stray fields. They are recorded by a second, thinner wire transversal to the first. The second wire is wound around the first wire over at least 360 deg., and moves around it. The first wire also moves relative to the second wire so that the AC leakage flux leaves magnetic marks on the test wire, which can be later detected by an ordinary magnetic head. Its output voltage is a measure for the presence and magnitude of the fault signal.

Title: Rotary piston engine with triangular rotor - has a cut out in which oval drive member fits, which reduces friction between rotor and cylinder
Inventor: OKADA FUKUMATSU
IPC: F02B53/00
Filed: 1976-04-08
Abstract: The rotary piston engine has a housing with two parallel sidewalls and a cylinder which is arranged between the two sides. The inner surface of the cylinder is epitrochoidal.

Title: Felting thermal bonding process - uses only air pressure loss at the back cloth to prevent shrinkage
Inventor: LUEPNITZ GERHARD
IPC: D04H1/541
Filed: 1976-10-06
Abstract: In a felting fabric composed of mixed fibres, there are crossing points of bicomponent fibres which can be bonded by applying thermal treatment to melt and fuse them together. A permeable back cloth is used to transport the material, with a sufficiently high air passage resistance to ensure, in treating a felting of continuous filaments, that the air pressure loss alone prevents then longitudinal shrinkage by holding them against the carrier. The system allows the use of a fan to recirculate the hot air as there is no need to pass the hot air downwards through the felting to hold it while thermally bonding the fibres.
