Abstract: A water-insoluble polymer powder that can be redispersed in a liquid phase is obtained by proceeding as follows: first prepare a two-phase liquid-liquid system from a concentrated aqueous solution of a solute and a solution of the polymer in an organic solvent which is at least partially miscible with water, and then add water to it until all of the organic solvent has diffused into the aqueous phase. The polymer microparticles are then washed and dried. When resuspended in water, they result in a pseudo-latex.

Abstract: A method of regulation in winding, wherein a number of separate rolls are formed around separate roll cores situated one after another and side by side while being supported by support members and loaded by linear loads produced by truncated rolls in a set of truncated press rolls. The distance at each particular time between at least one truncated roll in the set of truncated press rolls and a beam that loads the set of truncated press rolls is measured. Based on the measured distance, a measurement signal is passed to a regulator which provides a regulation signal to valves that control actuators of the beam so as to adjust the distance between the beam and the set of truncated press rolls to the desired value.

Abstract: NON-LINEAR ANALOG-TO-DIGITAL CONVERTER     Abstract of the Disclosure A first film disposed in a first direction on an integrated circuit chip and having uniformly spaced taps provides progressively increasing resistance values.  A second film disposed on the chip in a direction opposite to the first direction at a position displaced in any direction from the first film may have a construction corresponding to that of the first film.  First and second reference voltages may be respectively applied to the first and second ends of the first and second films.  Particular taps on the first film may be connected to taps in corresponding positions on the second film with corresponding voltages.  A plurality of differential comparators are provided, each with a signal input and a reference input.  Each comparator reference input is connected to an individual one of the taps on the first film, but not necessarily to successive taps.  The reference input connections to the taps may have a non-linear (e.g. a luminance) spacing in the first direction to provide a non-linear voltage (e.g. a luminance) relationship between such taps.  For low voltages, however, the reference input connections to the taps may have a linear spacing in the first direction to provide a linear voltage relationship between such taps.  An input voltage is applied to the signal input of all of the comparators.  Binary signals representative of the input voltage are produced by the comparator in which the input voltage is substantially equal to the reference input voltage introduced to such comparator.

Title: Dual parison extrusion head for multi-layer blow molding
Inventor: HIRSCHBERGER MICHAEL
IPC: B29C48/09
Filed: 1990-04-11
Granted: 1995-06-27
Abstract: Dual   parison   extrusion   head   for  multi-layer extrusion blow molding  in which a die body surrounds two parallel spaced mandrels to form two cylindrical passages from which  parisons  are  extruded.   A  series  of resin  supply conduits  are  provided  for  directing  each  resin  to  both passages.  The series of conduits are axially spaced in the extrusion head to direct a plurality of plastic resins to each of the passages to form a multi-layer parison.   The resin supply  conduits  are  symmetrical  about  a  vertical  plane transversely bisecting the extrusion head between the two passages to produce flow and thermal symmetry in the resin to balance the resin flow to both passages.  The resin supply conduits are configured so as to produce the dual parisons with the resin weld line of the multiple resin layers being located on the blow mold parting line.  The resin conduits are positioned to minimize the center distance between parisons to reduce the size of the extrusion head.  This is accomplished in part by feeding the resin downwardly before the resin flows into the cylindrical passages to form the parisons.

Abstract: Fast cure and "pre-cure" resistant thermosetting adhesives and methods for their production useful for binding lignocellulosic materials together, are disclosed.      A fast curing adhesive is obtained by cross-linking binary phenol-formaldehyde consisting of high average molecular weight phenol-formaldehyde (PF) resin and low average molecular weight PF resin with lignin. A  "pre-cure" resistant adhesive is obtained by cross-linking a PF resin, such as binary phenol-formaldehyde, with a lignin with the addition of ammonia preferably in the form of an ammonium salt. The lignin may be obtained from different wood pulping waste materials including that recovered from the sulphite, kraft, organic extract or steam hydrolysed wood pulping processes. The adhesive can be produced as an aqueous solution or dispersion, and used in either a basic or acidic environment. The quick setting and "pre-cure" resistant adhesives are inexpensive to produce and both display improved adhesion characteristics when compared with existing adhesives prepared from wood waste products. The adhesives also compare advantageously to a variety of existing commercial phenolic resin presently being used in the manufacture of wood composite products such as waferboards. These adhesives are capable of being spray dried more easily and produce higher yields, when compared with existing wood waste products which have been cross-linked with commercial PF resin or to a variety of existing commercial phenolic resins.
