Title: Fungicide and nematocid azolyl-formamidine derivs. - prepd. by reacting halo-formamidine derivs. with azoles e.g. imidazole
Inventor: REGEL ERIK
IPC: C07D285/12
Filed: 1975-11-06
Abstract: New azolyl-formamidine derivs. are cpds. Ac-C(NR1R2)=N-R3 (I) and their salts. In (I), R1 is alkyl or haloalkyl; R2 is opt. substd. phenyl, or an opt. substd. 5-membered heterocyclic residue with 1-3 hetero atoms (N, S); R3 is alkyl or opt. substd. phenyl; and Az is 1-pyrazolyl, 1-imidazolyl or 1-triazolyl. (I) are useful as fungicides and nematocides. Their fungicidal activity against fungal diseases of cereals is higher than that of related known carbamoylimidazoles such as 1-(3,4-dichloro-N-methylcarbaniloyl)-imidazole. (I) are esp. effective against true mildews, e.g. cereal mildews, and other cereal diseases such as cereal rust. Their effect is protective and curative. (I) may also be used against phytopathogenic nematodes. Toxicity towards warm-blooded animals is low. Specific cpds. (I) include N' -ethyl-N' -(2,4-dichlorophenyl)-N-isopropyl-l-imidazolylformamidine. In an example, this is prepd. by reacting N'-ethyl-N'-(2,4-dichlorophenyl)-N-isopropyl-chloroformamidine HCl in acetonitrile with imidazole in presence of NEt3.

Title: Two way valves in pressure balancing pipes - suppress contaminated gas flow in gas insulated switchgear by reacting to pressure rise
Inventor: GORZOLLA ROLF DIPL ING
IPC: H02B13/065
Filed: 1975-12-24
Abstract: To prevent undesirable flow of contaminated gas into clean parts of the system following a fault the bridging pipes are provided with two way pressure sensitive valves. These valves close due to sudden flow caused by a pressure rise consequent upon the heat generated by a fault. The defective portion is thus transiently isolated. A valve may comprise a local pipe section of larger diameter (14) with flanged ends (3), containing a disc (5) held by springs (6) on each side. A sudden increase in pressure and flow will push the disc in the flow direction until it seals onto the flange face (7) and prevents further gas transfer. With subsequent pressure reduction the disc returns to its normal position under spring action.

Title: Automatic timer switch for storage heaters - uses potentiometer with positioning means for moving slider contact (OE150276)
Inventor: BAEUML WALTER ING
IPC: H05B1/02
Filed: 1976-02-11
Abstract: The timer switch used to control day and night cycle of an electric storage heater, e.g. to allow the latter to use off-peak electricity, employes a potentiometer supplied with a constant current, with the slider contact determining the control voltage and driven in either direction by a positioning system. The positioning motor (1) drives a cog wheel which engages a pinion mounted on a pivoted lever (4), with the pivot axis and the cog wheel lying coaxially. The lever (4) pivots to allow the pinion to engage a cog wheel for changing the direction of movement of the slider contact, its axis rotating in the opposite direction to the motor drive shaft. The transmission ratio between the drives for the two directions of movement of the slider contact is the inverse of the required periods of movement of the slider contact in the respective directions.

Title: Multiple lift control system - has common signal wires between all lifts and control unit with evaluation circuits
Inventor: KRAUS HANS
IPC: B66B1/18
Filed: 1976-04-20

Title: Sender transmitting test signals from measurement points - transmits test signals in one direction and control signals in other over common line
Inventor: DAM POUL STEFFEN
IPC: G08C15/08
Filed: 1976-07-15

Title: Increased bearing strength device for porous ground - includes driving open-ended linings into soil to reduce lateral movement
Inventor: MATTSON ARNE
IPC: E02D35/00
Filed: 1976-09-03
Abstract: The bearing strength of porous ground can be increased by driving elongated linings (4) which are open at both ends vertically into the ground. By this means a predetermined volume of the soil is isolated from the surrounding soil in relation to lateral movement of the ground mass. The lining is circular in cross-section and an anti-friction agent is supplied to the lower leading edge. The lining is driven into the ground while being vibrated. In order further to increase the bearing strength of the ground, the soil volume enclosed in the lining can be compacted by compression or injection or both.

Title: Aerosol can spray head servo operating mechanism - has tapered pin with cylindrical ends acting on head button upper surface
Inventor: GOETZE RAINER ING GRAD
IPC: B65D83/16
Filed: 1976-10-13
Abstract: The servo system reduces the effort needed when actuating an aerosol can spray head. It has a taper pin with cylindrical end portions actuating the head, the pin and the cylinder in which it works being of injection-moulded plastics with a low coefficient of friction. When the pin is pressed right in, continuous spraying is possible without finger pressure.

Title: Finding correlation function maximum - is by auto-correlator balancing determination of band central frequency using delay circuits
Inventor: MESCH FRANZ PROF DR ING
IPC: G06G7/19
Filed: 1977-02-04
Abstract: The method of finding the max. of a correlation function is by determination of the central band frequency in a measurement sensor output signal avoids disadvantages of analogue low pass filters such as frequency offset, drift errors due to temp. variation etc., and bandwidth limitations for large speed ranges of measurement. The sensor output is input to an auto-correlator with at least one control circuit. A controller input signal is formed using delay elements giving signal delays with mutual whole number relationships. The control signal is input to an integral controller whose output adjusts the delay element time until the autocorrelator is in balance.

Title: Acoustic signal transmission curve equalisation process - uses correction at key frequencies with interpolation producing polygonal correction curve
Inventor: HUBER BERNHARD DR
IPC: H04B3/14
Filed: 1977-04-09
Abstract: The apparatus is used for correction of attenuation curves with correction of resonance errors in both amplitude and frequency. The attenuation curve (1) to be corrected may have one or more sharp resonance peaks. In the correction of resonance errors in the attenuation curve use is made only of the degree of attenuation at discrete frequencies in the transmission band and correction is made in both amplitude and frequency. A polygonal response curve may be produced. The discrete frequencies used in choosing correction values may lie between filter transmission channels. The system reduces the number of discrete frequencies needed.
