Abstract: ABSTRACT OF THE DISCLOSURE Coating compositions comprising an alkylated urea-formaldehyde resin and a polymethylol cyclchexane, which are useful for low temperature cure and are low in viscosity to allow ease of coating without the need for appreciable amounts of solvent thinners The alkylated urea-formaldehyde conden-sates have an average degree of condensation of about 3 or less and a combined urea:formaldehyde:alcohol ratio in the range of about 1:2-3:1-2.5. The compositions may be cured in the presence of acid catalysts in the temperature range of 70 to 105°C., and are particularly useful for coating paper, cloth and wood substrates.

Title: Preparation for protection of emerging  sugar beet against damping-off and method  of its production
Inventor: VESELY DASA
IPC: A01N63/04
Filed: 1979-07-04
Granted: 1982-10-12
Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a dry powdered preparation to be applied onto sugar beet seeds, the preparation containing, as its active consti???    organs of reproduction of Pythium oligandrum Drechsler, particularly the oospores, in a sufficient-ly high concentration of at least about 1,000,000, preferably at least about 4,000,000 per gram (most preferably in the range of 50,000,000 - 500,000,000 per gram).  Such concentrations enable to apply more than 100,000 oospores or more onto every seed, which proved sufficient to secure protection of emerging suger beet plants against "damping off" or "black leg" disease.          Although the mycoparasitism of Pythium oligandrum has been dis-covered many years ago, its use for biological protection re-quired a lot of research work establishing the conditions necessary for obtaining reliable results on a large scale.          Crucial conditions are: a) dry powdered preparation, and b) an unusually high concentration of oospores, namely at least about 1,000,000, (preferably in the range 50,000,000 - 500,000,000 per gram) measured in a known way using a B?rker's chamber.          The most suitable method for producing such powdered preparation consists in cultivating Pythium oligandrum in stationary cul-tures on grain or corn substrate wetted with liquid nutrients containing, in addition to usual constituents such as sugars, corn-steep liquor, and mineral salts, from 2 to 3 percent of calcium chloride.  The sterilized substrate is then inoculated with Pythium oligandrum Drechsler and the cultivation is carried out preferably under semi-sterile conditions, the substrate being irradiated with visible light, advantageously through a blue or green filter.  Another feasible method consists in submerse cultivation of P. oligandrum and subsequent dehydration of the fermented mash either by adding substances capable of binding water such as sugars, starch or mineral salts, or by lyophilization, or by spray-drying.  In any case the substance is dried and ground at temperatures not exceeding 35°C.  The powdered preparation thus obtained is ready for use and can be stored for several months without losing mast of its activity.

Abstract: RADAR SPEEDOMETER     Abstract Method and apparatus for measuring the speed of a land vehicle over a surface.  A narrow beam (16) of RF energy is directed toward the surface (18) at a sub-stantial angle.  Reflected RF energy is mixed with that transmitted to produce Doppler signals having a spectrum. The spectra of the Doppler signals are normalized by the Doppler signals being applied to an AGC circuit (26) so that the maximum amplitudes of the spectra are substan-tially constant and being applied to one or more tracking band pass filters (30, 32, 34) which eliminate unwanted frequency components in the spectra.  From the normalized spectra, output signals are produced from which can be determined the speed of the vehicle relative to the surface.

Abstract: ABSTRACT An apparatus and method for dynamic testing of a rotary movement-electric signal transducer system, such as found in an automotive anti-blocking system, are disclosed.  The method comprises receiving the signals generated by the system during operation measuring the time of each of the signals to establish the periods therefor, comparing the periods to deter-mine a maximum period and a minimum period thereof, determining an average period for the periods and comparing the average period to the minimum period and the maximum period to provide a first evaluation interval and a second evaluation interval, respectively.  A reference interval which represents the maximum permitted duration or tolerance is generated and this is compared to the first evaluation interval and the second evaluation interval.  A positive test signal is then generated when the first and second evaluation intervals are each less than the reference interval.

Abstract: FULL FREE-LIFT UPRIGHT FOR LIFT TRUCK        Abstract A lift truck upright having a fixed upright section, a telescopic upright section, and a load carrier mounted on the latter section. An asymmetric lift cylinder assembly is located adjacent one side of the upright in a position which provides improved overall operator visibility through the upright. The lift cylinder is adapted to be operatively connected to the telescopic upright section by means of lifting chain structure which traverses across the upright and which is reeved on spaced and rotationally aligned sprockets supported from the cylinder assembly, the one chain end structure being connected sub-stantially centrally of the load carrier and the other chain end structure being fixedly secured substantially outwardly of one side of the cylinder assembly. The cylinder assembly is positioned at or near a location which is one-half the projected distance between the chain end connections, or in a broader sense, approximately midway between the vertical central plane of the load carrier and the chain end connection outwardly of the cylinder assembly. It preferably comprises a cylinder assembly supported from the one side of the upright at an elevated position and having an effected stroke of substantially one-half the height of the collapsed upright.     A cantilevered cylinder is supported from the telescopic section for elevating thereon the load carrier to a full free-lift position, the asymmetric cylinder operating subsequent to the operation of the cantilevered cylinder to actuate the telescopic section together with the load carrier to maximum elevation. A fluid pressure supply hose is connected between the base ends of the cylinder assemblies and is reeved in a loop for movement with the asymmetric cylinder assembly. In any upright using this invention the asymmetric cylinder assembly is located such that it projects at least partially into the area of interference by the adjacent side of the upright when in a retracted or collapsed position with the visibility of the operator form his normal line of sight through that side of the upright, and preferably projects partially also into the longitu-dinal plane of that side of the upright.

Abstract: PROCESS AND THREAD INSERTER FOR THE    MANUFACTURE OF A BELTING WITH     TUBULAR EDGE PORTIONS            Abstract Belting for use preferably for safety belts in motor vehicles has a single layer woven central portion and two tubular edge portions and is made on a needle belt weaving loom provided with a knitting needle.  One tubular edge portion is closed by a row of stitching that does not lie at the outer edge of the edge portion but disappears into the fabric at the edge of the central portion.  By means of the invention the rate of production is increased by using two weft thread insertion needles that simultan-eously insert two weft threads at each pick.  A common shed for these needles is formed by the two outer edge warp threads.  For weaving the edge parts between the central portion and the two outer edge warp threads, an upper shed and a lower shed are formed.  Of these, one shed accepts the first weft thread insertion needle which forms the edge fabric and the other the second weft thread insertion needle.  A loop is drawn by the knitting needle outside the edge part through a loop of at least one of the weft threads to form a stitch.
