IPC: A01C1/04
Filed: 1987-02-20
Abstract: For the individual sowing of light and/or delicate seeds, a mixture of flowable material and seed grains is made and the mixture is distributed, preferably in the form of drops, in metered part quantities on a seed bed. The flowable material used is a high- viscosity fluid to which a predetermined quantity of seed grains per unit volume is added. The viscosity of the fluid can be matched to the weight of the seed grains to be mixed in. A bottle-like container, the outflow orifice of which is assigned a drop dispenser, can be used as a device for discharging the metered part quantities, preferably in the form of drops. <IMAGE>

Abstract: The invention provides a method of manufacturing a synthetic-resin fibre, in which decomposition of the polymer molecules is avoided, and in which no solvents have to be used. A starting material which comprises at least an oligomeric compound is extruded from the melt to form a liquid thread, after which the starting material is polymerized by subjecting it to actinic radiation. 
     The method is particularly suitable for the manufacture of a molecularly oriented synthetic-resin fibre, for which purpose the liquid thread is subjected to an elongational flow, after which the thus oriented oligomeric compound is polymerized. The synthetic-resin fibre obtained by this method has a particularly high density of cross-links between the polymer chains.

Abstract: A liquid filtering apparatus wherein solids suspended in the liquid are accumulated to form a cake on a filter media (40) as the liquid passes through the media (40). Upon the buildup of such solids, pressurization upon the liquid forces remaining liquid through the media 40. Such pressurization is inactivated upon excessive cake buildup, and a conduit (25) helically wound about the outside of the filter media is expanded by air pressure. The conduit (25) is attached at various points about its length so that it forms chord lines between such connection points. Such expansion and chording of the conduit breaks the cake from the media (40).

Abstract: The installation comprises in particular a boiler (1), pipes (2) for distribution in a closed circuit of a heat-exchanging fluid to different heating points (3) such as radiators, convectors or floor heating, and a circulating pump (4) for said heat-exchanging fluids. According to the method of the invention, the temperature of the fluid is measured at the outlet of the boiler (1), the temperature of the fluid is measured at the return of the boiler (1) and the divergence between the two temperatures previously measured is calculated. The temperature divergence found is compared to an ideal divergence dependent upon the temperature of the fluid at the outlet of the boiler, which makes it possible to determine a differential divergence. The heating rate of the boiler, that is to say the outlet temperature of the heat-exchanging fluid, is adjusted to reduce the differential divergence. The invention will be of particular interest to heating specialists. <IMAGE>

Abstract: A discharge machining controller in which a power source for discharge machining of a wire cut electric spark machine is controlled depending upon a leakage current that flows through a wire electrode (2) and a work (3), in order to obtain stable electric discharge and favourable surface coarseness, In the controller, a peak value of machining voltage applied across the wire electrode (2) and the work (3) is detected by a peak voltage detector circuit (D4, R8, R9, C2). As the leakage current increases and the detected value decreases, the ON time and OFF time of switching elements (Tri, Tr2) that exist between the DC power source (1) and the wire electrode and work are switched from values smaller than a time constant (R1.C1) of the charge/discharge circuit into larger values, whereby the machining voltage increases. When the leakage current decreases again, these values are switched into values smaller than the time constant. This makes it possible to maintain the effective machining voltage it a proper value.
