Patent NL-6907833-A (NL)
Title: Polymer processing method
IPC: B29C48/03
Filed: 1969-05-22
Abstract: Processing of a polymer produced by injecting a polymer soln. into a chamber, in which the polymer is converted into thread form and the solvent evaporates and is discharged, is effected by continuously accumulating the polymer, and compressing the accumulated polymer in at least two stages to a product with sufficient density to be processed in limited proportions by an extruder. The second stage is carried out when the polymer is under the final pressure of the print stage, the compression direction in the second stage being perpendicular to that used in the first stage. The apparatus includes two plates, one of which can be moved towards and away from the other. The fixed plate may be formed by the sidewall of the chamber. The chamber is provided with a base on which the movable plate stands, the plate being displaceable along the base. The edge of a collection plate connects with the upper edge of the movable plate, the collection plate being situated on the side of the movable plate directed away from the fixed plate. The movable plate is formed by the base of the chamber which is rotatable around a horizontal axis. The method increases the density of the light polymer thread in the accumulation from abt. 1g/dm3 to 400g/dm3 in the compressed product. The compressed product, unlike the light polymer thread, does not tend to be carried away in the solvent stream. The compressed product is easily processed by an extruder.

Patent NL-7507428-A (NL)
IPC: H05B3/56
Filed: 1975-06-20
Abstract: A beam of charged particles is deflected in a closed path such as a square, for example, over a cross wire grid at a constant velocity by an X Y deflection system. A small high frequency jitter is added at both axes of deflection to cause oscillation of the beam at 45 DEG to the X and Y axes. From the time that the leading edge of the oscillating beam passes over the wire until the trailing edge of the beam passes over the wire, an envelope of the oscillations produced by the jitter is obtained. A second envelope is obtained when the leading edge of the beam exits from being over the wire until the trailing edge of the beam ceases to be over the wire. Thus, a pair of envelopes is produced as the beam passes over each wire of the grid. The number of pulses exceeding ten per cent of the peak voltage in the eight envelopes produced by the beam completing a cycle in its closed path around the grid are counted and compared with those counted during the previous cycle of the beam moving in its closed path over the grid. As the number of pulses decreases, the quality of the focus of the beam increases so that correction signals are applied to the focus coil in accordance with whether the number of pulses is increasing or decreasing.

Title: Modifying starch with casein or a caseinate - giving a complex with limited thickening and swelling properties, e.g. for use in foods
IPC: C08B31/00
Filed: 1977-10-07
Abstract: Modified starch prods. are made by treating starch with caseine or a caseinate at greater than the gelation temp. of the starch to form a complex. The reaction is carried out e.g. by (a) dispersing the caseinate in water at a relatively low temp., (b) adding the starch to give a caseine/starch ratio of 1:16 to 3:2, esp. 1:2 to 4:3; and (c) completing the reaction with continuous stirring. The process allows prodn. of purpose-modified starches for a wide range of applications. The material becomes less sticky and gummy which is useful in semi-fluid prods e.g. of meat and fish. Flow properties are different of e.g. to cold swelling starch and emulsion stability is improved. The degree of thixotropy and elasticity can be reduced to zero and the modified starch has no after taste.

Patent NL-8201614-A (NL)
IPC: G11B15/467
Filed: 1982-04-19
Abstract: A video recorder wich is adapted to reproduce video signals recorded on a record carrier in the form of a tape in tracks which are parallel to each other and which are inclined relative to the longitudinal axis of the record carrier with a speed which deviates from the nominal speed. The video recorder comprises tracking-error detection means for detecting the deviation of the read head from the centre of the track to be followed. The generated tracking-error signal is applied to the tape-transport control loop. For the purpose of tracking-error detection a reference-signal generator generates reference signals which form an identification for the track to be followed. For reproduction with a deviating speed these reference signals are generated in such a pattern that this pattern corresponds to the sequence of tracks which the head would scan in the case of a free uniform motion with a constant-tape transport speed which deviates from the nominal speed, so that when such a pattern is generated the tape-speed control will establish a tape-transport speed corresponding to this pattern.

Title: Process for preparing a bentonite-sulfate fabric softening particulate agglomerate and detergent compositions containing it
Inventor: RAMACHANDRAN PALLASSANA N
IPC: C11D3/04
Filed: 1986-03-12
Abstract: Agglomerated particles of finely divided fabric softening bentonite and sodium sulfate particles have been found to possess improved fabric softening properties, compared to agglomerated bentonite, especially when employed in the hand washing of laundry which is subsequently line dried. Such agglomerates are also of excellent particle strength and are readily dispersible in water. The described product may be made by agglomerating finely divided bentonite and sodium sulfate powders with the aid of excess moisture, after which the agglomerated particles resulting are dried and those of desired size, preferably in the No's. 30 to 100 sieve size range (U.S.), are obtained. The fabric softening agglomerate made may be mixed with spray dried synthetic organic anionic detergent composition beads of about the same or lower bulk density, preferably in the 0.3 to 0.5 g./cc. range, with about 5 to 30% of the agglomerate particles being present, to make a non-segregating fabric softening particulate detergent composition of improved softening properties. Detergency, soil anti-redeposition properties, bead physical characteristics and processing are improved by the presence in the detergent composition of a minor proportion of a water soluble copolymer of maleic and acrylic acids which, unlike other polymers which can impart such properties to detergent compositions, does not adversely affect the softening of hand washed laundry by the present agglomerate. Soda ash may be used in place of some or all of the sodium sulfate of the agglomerate and a good softening additive will also be obtained.
