Patent DE-1933498-A1 (DE)
Title: Aerosol prodn
Inventor: DAULANGE JACQUES
IPC: B01F3/04
Filed: 1969-07-02
Abstract: Aerosols are produced in equipment containing an air compressor, a first line connected with this, a sealed vessel for a liquid in which the compressed air line dips, a device between vessel and compressor. A second line dips into the liquid, and has, at its other end, a device adjacent to the first, and a heater plate perpendicular to the axis of the first device. The two devices together form an atomiser, with reduced air consumption since a homogenised air-liquid mixture, even an emulsion, may be formed in the liquid vessel. The production of a dry aerosol, as required for example in room disinfection, is ensured by impingement of the mist on a heated plate at a thermostatically controlled temperature.
Patent DE-1946541-A1 (DE)
Title: Handling equipment for radioactive objects - esp exchanging reactor fuel
Inventor: SCHOENING JOSEF DIPL-ING
IPC: G21C19/06
Filed: 1969-09-13
Abstract: The element to be exchanged is an opening in the wall of the reactor which can be covered by a sliding massive plate with a single opening in it matched to that in the wall. Below that plate is a magazine with a number of parallel channels, again of the same diam. into which and from which the elements may be withdrawn or expelled by a hand operated ram mechanism also mounted on a cross slide. The head of the ram and/or the bases of the elements to be changed are shielded. Locking devices in the bores of the wall and the magazine are used to retain the elements in position.
Patent DE-1952426-A1 (DE)
Title: Vent outflow of condensation polymer is heat-controlled - by signals from a flow meter and comparator
Inventor: LAL GUPTA KASHMIRI
IPC: B01J19/00
Filed: 1969-10-17
Abstract: Greater homogeneity is obtained when batch-producing high pressure condensation polymers, such as polyamides or polyesters. by using an apparatus having a reaction chamber with a heating coil and a vent and a control system comprising a flowmeter connected to the vent and emitting a signal for the actual outflow, while a timing device emits a signal for the desired outflow, the two signals being checked by a comparator which emits a signal for actuating a regulator adusting the heat flow to the polymer. Advantage of the system is that less deviation from the norm occurs than in open cycle systems.
Patent DE-1961175-A1 (DE)
Title: Heat treatment of mesh goods to reduce - shrinkage
Inventor: KAUFMANN GERHARD DIPL-ING
IPC: D06C7/02
Filed: 1969-12-05
Abstract: Net or mesh goods, made from synthetic fibres capable of being heat fixed, are treated to reduce shrinkage by heat fixing the goods before dyeing by steaming at above 125 degrees C. The goods are pref. made of textured polyester yarn or yarn from a mixture contg. such fibres. Thermofixing may be carried out under vacuum while stretching the goods longitudinally and/or latitudinally.

Patent DE-2307754-A1 (DE)
Title: Multilayer electrical conductors mfr. - by forming contacts by partial etching of coated substrate
Inventor: KIKUCHI AKIRA
IPC: H01L23/522
Filed: 1973-02-16
Abstract: A thin surface layer of metal is oxidized to a porour film and a light-sensitive film is provided upon the porous film. The light-sensitive film is developed to form a mask over the area of the metal layer that will form contacts. Etching is then effected with an agent which dissolves the oxidized film faster than the metal layer. This results in lateral material removal to give an etched contact with gently sloping sides. After removal of the oxidized layer, coatings are applied to the contact to build up the multilayer conductor.

IPC: C04B28/02
Filed: 1973-03-09
Abstract: Mortar compsn. for use as an underlay for ceramic plates contains (in pts. wt.): quartz gravel 100, cement 33, and a binder 8-12 (pref. 10). The binder consists of (in wt.%: acrylic resin 10-15, polyvinyl propionate 3-8, CaCl2 2-6, and water 75-80. Introduction of polyvinyl propionate improves compatibility of CaCl2 (used as a setting accelerator) with the resin (CaCl2 tends to cause premature coagulation of resin emulsions). The ceramic plates can be laid after 24 hrs. as the underlay reaches, at that time, a strength of 110-150 kg./cm2 and the residual moisture content is 4%. The thickness of the underlay can be 5-100 mm. and can be formed at 10-25 degrees C.

Title: Oil-in-water emulsion treatment - by oil sepn at temp to make emulsifiers inactive
Inventor: PREEN WOLFGANG VON DR ING
IPC: C10G33/00
Filed: 1973-04-30
Abstract: Spent oil-in-water emulsions (e.g. cutting oils for machine tools) are purified before being discharged into the drainage system. The emulsion is preheated in a counter-current with already broken hot emulsion, followed by heating to a temperature above 100 degrees C. at which the emulsifiers are made inactive. Water evaporation is prevented by an appropriate pressure. The emulsion is then cooled in a first heat exchanger to just above the water boiling point, the oil is removed in an oil separator, and the oil free water is cooled finally in a second heat exchanger. This system requires no chemicals and has very low running costs. The power costs are much less than with evaporating systems.

Title: Converting pulse code modulation into delta modulation signals - involves input memory with digital integrator and comparator which feeds second memory
Inventor: DESCHENES PIERRE A
IPC: H03M7/00
Filed: 1973-07-17
Abstract: The delta modulation transmitter features a pulse generator with a modulator and a comparator which discriminates between the instantaneous amplitude of the analog input with the output signal of integrator. The polarity of the output signal corresponds to the difference between the two signals fed to the comparator and controls the pulses of generator fed to modulator. The first memory stores the input signal with m digits and representing the quantized signal of the PCM period, while the second memory connected to the comparator holds the output signal representing the delta modulated signal.
Patent DE-2338368-A1 (DE)
Title: Emergency call location monitoring - involves using D.C. marking pulses picked by relay which are converted into audio frequency signals
Inventor: MATTHES HANS-GERT
IPC: H04M11/04
Filed: 1973-07-26
Abstract: The d.c. pulses sent by the caller through the telephone transmission line are received by a relay and are converted by a transmitter which then sends the audio frequency signals by an emergency call line. The signals reaching the receiver and discriminator are delayed for feeding an impulse relay whose contact provides an acknowledgement signal. The presence of the latter in the transmission line is in an indication of the location point while the absence of the signal signifies a fault in the line.

Title: Swivel fixture for adjustable bed settees - has spring-biased scissor-like levers and joint for easy handling and stable use
IPC: A47C17/28
Filed: 1973-09-03
Abstract: The swivel joint comprises two opposing pivots each attached to a scissor-like lever which is rotatably connected to a second such lever by a scissor-like joint. The end of one lever remote from the joint is mounted in a fulcrum which is stationary relative to the frame whilst the corresponding end of the other lever is guided to move relative to the frame and is biased by a spring in the direction of the fulcrum of the first lever so that an upwardly direct force is effective at the pivot. The pivot supporting the movable upholstered unit is thus fastened to a scissor-like unit which extends horizontally and is biased by the spring in the closing direction.

Title: Vehicle fuel tanks permanent magnet closure - is openable by energisation of electro-magnet provided in closure seat
Inventor: PROKS JAROMIL DIPL ING
IPC: F16J13/02
Filed: 1974-03-02
Abstract: The closure, e.g. a cap for a vehicle petrol tank, has a cover including an annular permanent magnet which keeps the cover closed by attraction to an annular member of magnetic material secured to the seat of the cover. The member is also the core of a winding of an electro-magnet whose polarity is so chosen that, upon energisation, the electromagnet repels the permanent magnet and thereby opens the closure. Above the winding there is provided a further member of magnetic material on which the permanent magnet tends to "float" after release by the electro-magnet. This prevents falling away of the closure after release.
