Title: Impregnation and void filling in motor windings - using a two component synthetic resin filler
Inventor: KALLAS HANS DIPL ING
IPC: H02K3/32
Filed: 1976-04-21
Abstract: The epoxy resin filler and impregnant of the parent patent is replaced by a modified organo-polysiloxane resin which gives generally higher insulation resistance exp. under moist or wet conditions and when drying out from such conditions. The improvement obtained is of the order of 105. The resin cures at room temp. It possesses food flexibility combined with a low Shore hardness which prevents cracking of the filling due to unequal expansion between core and windings.

Title: Preheating fuel for IC engine - using exhaust gas passed through heat exchanger to preheat air fuel mixture before it enters cylinder
Inventor: CRETEUR JEAN
IPC: F02M31/08
Filed: 1976-05-13
Abstract: The engine has a cylinder (38) with a sparking plug (51) supplied from a distributor (43). Air is drawn in through a filter (13) and mixed with fuel oil in a carburettor (12). The air fuel mixture passes through a heat exchanger (5) in which it is heated by a stream of exhaust gas also flowing through the heat exchanger. The heated air fuel mixture is then admitted into the cylinder (38) before the igniting spark is made between the electrodes of the plug (51). The exhaust (52) from the cylinder flows through the heat exchanger (5) before passing to the silencer (53) and being discharged to atmosphere. A separate intake (8) with petrol as a fuel is used for starting purposes. This mixture does not need preheating.

Title: Heat pump for swimming pool heating systems - uses combustion energy to evaporate cooling medium, to drive motor
IPC: F25B27/00
Filed: 1976-08-03
Abstract: The heat pump is esp. for heating systems, having a cooling medium circuit and a motor to operate a heat pump compressor. Compressor and motor are located on a common shaft.

Title: Noise suppression gate circuit for AM radio receiver - has second gate and second demodulator to fill breaks when first noise gate opens
Inventor: HANSEN JENS DIPL ING
IPC: H03G3/34
Filed: 1976-09-23
Abstract: The noise suppression circuit, for an AM radio receiver, has a gate in the LF signal path opened, when a noise pulse is detected. The gate is connected to the output of the mixer/filter stage andis followed by a bandpass filter, amplifier and the AM demodulator. The amplifier output is gated by a second gate operating out of phase in relation to the first one, to a second bandpass filter and a second AM demodulator. The outputs of the two demodulators are added and the sum used to drive the loudspeaker output stage. The second demodulator compensates for the break caused by the opening of the first gate due to noise.

Title: Industrial filter with filtering cells and distributor - that has circular collecting and distributing parts for fluids from the cells which rotate in relation to each other
Inventor: DAVISTER ARMAND
IPC: B01D33/82
Filed: 1976-10-08
Abstract: Distributor for use in industrial filters consists of a distributor and a collector which can rotate w.r.t. each other. The collector is divided into (a) chambers and (b) compartments which are cut off by partitions. The compartments are connected with aspiration device(s) and liquid removal device(s). The chambers are isolated and each is connected to an aspiration and pressurising device. The distributor has openings which are arranged w.r.t. to the compartments, and chambers so as to connect each filter cell successively with each of them. Each compartment has a liquid outlet below the level of the openings and, above the maximum liquid level, a passage connected to a gas aspiration device. Gases and liquids are thus separated and follow different paths through the compartments. Gases separated from the liq. are removed from the distributor outlet and liquids free from undissolved gas are collected across the evacuation outlets. The device prevents encrustation and crystallisation in the distributor.

(I) where R are only H, alkali and/or NH4 ions are used as (i) retarders for gypsum setting and (ii) complex-formers for metal ions, e.g. Fe and alkaline earth metals. Plasticiser concn. in PVC may be 20-50wt.%. Gypsum setting retarders are superior to citric acid and are used in 0.06-0.09wt.% concn. The complex-formers can be used for cleaning glass articles, e.g., in bottle washing compsns. In an example, 3,3-diphosphono-pimelic acid was prepd. by (i) reacting 4 mol. Et acrylate with 2 mol. tetra-Et methane-diphosphonate and (ii) acidolysis of the hexa-Et ester obtd.

Title: IC engine fuel mixture control - has filter circuit in feedback path of exhaust gas oxygen detector
Inventor: RABUS FRIEDRICH DIPL ING
IPC: F02D41/14
Filed: 1976-10-29
Abstract: An internal combustion engine has an oxygen detecting transducer (7) in the exhaust pipe which produces an electrical signal (Us). The signal is put into a comparator (3) which is also fed (5) with a base signal (Uv). The transducer output is also fed into a control control circuit (9) which consists of a low pass filter (10) and an integral controller (11) which regulates the mixture strength. Its output is also fed back through a resistance (12) to the output connection (P1) of the transducer. The integrator is also fed with the base signal (Uv). The circuit filters out high frequency transients in the transducer output so that the controller acts only on the direct current component. This enables a constant base signal to be used at all engine conditions.

Title: Night storage heating system with outside thermostat - has additional thermostat ensuring low temp heat and prevents icing
Inventor: HERBIG HELMUT
IPC: F24D19/10
Filed: 1976-12-13
Abstract: The heating system has thermostat which interrupts energy supply over certain periods when a specific temp. is exceeded. This arrangement is used for ensuring night time heating at lower temp. The temp. is regulated so that rooms are not cooled excessively and the heating system is prevented from freezing. The outside temp. operated thermostat which interrupts energy supply, is bypassed by an additional thermostat which measures the heat flow directly or indirectly. The first thermostat is bypassed when temp. sensed by the second thermostat sinks below a specific temp. The additional thermostat in the heating fluid stream is set at about plus five degrees centigrade.
