摘要： What is claimed is a magnetic storage medium in which the polyurethane binder system forms a three-dimensional network independently of reactive low molecular weight substances present on the magnetic pigment or in the dispersion and the production of such a storage medium. The binder in the colored magnetic layer consists of a reaction product of polyisocyanates having an average functionality of from 2.1 to 4 (A) with predominantly difunctional aromatic amino-terminated polyurethanes having an average molecular weight of at least 10,000 (B) and optionally one or more hydroxyl group-containing polyesters having an OH number of from 100 to 450 (C), and/or predominantly difunctional aromatic polyamines having a molecular weight of from 100 to 400 (D) the ratio of isocyanate groups present in (A) to the isocyanate reactive groups present in (B), (C) and (D) being from 0.3:1 to 20:1, preferably from 0.8:1 to 20:1. With this binder system, it has been possible to achieve direct linkage of the polymeric binder chains and to suppress side reactions. This has enabled a soft polyurethane agent to be used, with the result of smooth dispersion of the magnetic lacquer and hence increase in the signal/noise ratio of the magnetic recording medium. The subsequent cross-linking which takes place according to the present invention enables the mechanical properties of the recording medium to be adjusted to the exact result required after the magnetic lacquer has been applied to a support.

摘要： There is disclosed a drip-forming device and system for drip irrigation. The device includes a tube and a rod having one end inserted into the tube by an adjustable amount, the rod being formed with at least one longitudinal groove which extends along at least part of the length of the rod and which is in communication with the part of the interior of the tube not occupied by the rod and whose depth decreases progressively away from the said one end over at least part of the length of the groove. With such devices, the output of each device can be simply adjusted to suit the local requirements, irrespective of the size, alignment and supply pressure of the complete irrigation apparatus, by adjustment of the depth of insertion of the rod in the tube. For a constant pressure the water output decreased with increasing depth of rod insertion -- i.e., as the minimum cross-section of the groove at the point of insertion of the rod in the tube decreases. At different pressures depending, for example, on gradient, the water output from different devices can be made equal by varying the depth of insertion of the rods in the tubes appropriately, such depth being increased as the pressure increases - i.e., the minimum cross-section has to be decreased.
