Abstract: CARDBOARD BUILDING STRUCTURE AND METHOD          ABSTRACT     A cardboard  structural member  for use  in the construction of building panels and a method of making same.   The structural cardboard member comprises an elon-gated hollow channel member of rectangular cross-section formed of  corrugated cardboard sheeting.    The channel member defines opposed parallel walls and is opened at its ends.   One pair of parallel walls terminates short of the ends  of  the  structural  cardboard  member  to  define  a connecting channel across the ends for receiving a rigid structural member thereacross between two opposite walls when  assembling  the  panels  to  construct a  building structure.   The method of assembly consists in glueing a plurality of these structural members side by side to form the panels.

Title: Method and device at manufacture of fibre pulp
Inventor: NILSSON KJELL R S
IPC: D21B1/12
Filed: 1988-04-14
Granted: 1992-10-06
Abstract: Abstract Method and installation at manufacture of fibre pulp of lignocellulose material.  The material in the form of cold chips or the like is fed into and preheated in a preheater (1).  Therefrom the material is fed into a defibrator (2) with a pressure housing and defibered to pulp while simultan-eously generating steam.  Pulp and steam flow through a blow pipe (3) to a steam separator (4) from which the pulp is discharged in the form of an air-tight pulp plug and the steam is returned to the preheater through a steam passage (5). The pressure in the system is maintained by the generated steam which produces a pressure maximum in the grinding housing while simultaneously the cold chips produce a pressure minimum in the preheater (1).  The flow resistance in the blow pipe (3) and the steam passage (5) is lower than through the material feed to the defibrator (2) so that the steam flows from the defibrator (2) via the steam separator (4) to the preheater (1).

Title: Ice detector
Inventor: WEINSTEIN LEONARD M
IPC: G01R27/26
Filed: 1988-05-26
Granted: 1991-04-23
Abstract: ABSTRACT OF THE DISCLOSURE      An ice detector is provided for the determination of the thickness of ice on the outer surface of an object (e.g., aircraft) independently of temperature or the composition of the ice.  First capacitive gauge, second capacitive gauge, and temperature gauge are embedded in embedding material located within a hollowed out portion of outer surface.  This embedding material is flushed with outer surface to prevent undesirable drag.  First capacitive gauge, second capacitive gauge, and temperature gauge are respectively connected to first capacitance measuring circuit, second capacitance measuring circuit, and temperature measuring circuit.          The geometry of first and second capacitive gauges is such that the ratio of the voltage outputs of first and second capacitance measuring circuits is proportional to the thickness of ice, regardless of ice temperature or composition.  This ratio is determined by offset and dividing circuit.

Title: Ferroresonant constant ac voltage transformer
Inventor: TOMINAGA FUKUTOSHI
IPC: G05F1/13
Filed: 1988-06-15
Granted: 1992-06-16
Abstract: FERRORESONANT CONSTANT AC VOLTAGE TRANSFORMER               Abstract of the Disclosure The primary and secondary windings of the transformer are each formed of a pair of independent windings, the first winding formed on the iron core of one of the phases and the second winding formed on the iron core of the phase adjacent thereto are connected to each other, and these serially connected windings are regarded as one phase winding respectively and are connected to each other in delta connection or Y connection.  A variation in the voltage phase caused by a change in the load current of one of the phases has an influence not only on the phase of interest but also on the phase adjacent  thereto and consequently enables the deviation in the phase difference between the output phase voltages due to loss of balance of the load to be decreased to about one half.  When the leg parts of the iron cores of the two adjacent phases are juxtaposed and a common winding is formed on the juxtaposed leg parts so that one winding may function equivalently as two windings connected in series, the number of windings required in all is one half of the number of windings required where the windings are formed independently on the leg parts of the cores.

Title: Method, a compound, and a blowing agent for making plastic foam
Inventor: OSTERGAARD HANS J
IPC: C08G101/00
Filed: 1988-07-15
Granted: 1993-05-25
Abstract: A b S T R A C T :            It is well known that the use of the blowing agent monofluortrichloromethane, also called Freon 11 or R-11, for the production of polyurethane foam is highly disadvantageous in -that R-11 has a decomposing effect on the ozone layer around our planet. In spite of a vast scientific research it has not so far been possible to provide a practically usable substitute for R-11, but such a substitute of a simple nature is provided by the invention. According to the invention use is made of a mixture of specific substances, which are generally undangerous in use and also otherwise advantageous, but the boiling points of which are so remote from the usual working temperature that each one of the substances will be totally unusable for the purpose. The two primary substances are 1.1.1. trichloroethane and R-22 with boiling points 75-76°C and -41°C, respectively; when these substances are mixed and are mixed into the compound to be foamed the process conditions will widely correspond to the use of R-11, though further advantages are achievable.

Granted: 1993-01-05
Abstract: REMOTE RECONDENSER WITH INTERMEDIATE                TEMPERATURE HEAT SINK             Abstract of the Disclosure A recondenser with a primary heat exchanging surface for recondensing boil-off within a cryostat provides a second heat exchanging surface for removing heat leak into the cryostat.  The second surface is cooled by the same working fluid that cools the primary surface, but at a temperature intermediate that of the primary surface and associated cooling apparatus which is remote from the cryostat.  An intermediate transfer line transfers working fluid from an intermediate portion of the cooling apparatus to the second surface which is in heat exchange relation with a radiation shield of the cryostat but is out of physical contact with the radiation shield. The cooling apparatus includes a mechanical refrigerator which further cools working fluid returned from the second surface through the intermediate transfer line.  The intermediate transfer line is preferably positioned in a non-contact helical manner about a final transfer line which carries the working fluid to the primary surface.  The two transfer lines form an assembly which is less than about one inch in outer diameter and is removeably positioned in the cryostat.  The intermediate transfer line is thermally isolated from the final transfer line within the assembly.

Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith high tensile modulus and high sag resistance without increasing melt viscosity, and a method of making the same. The graft copolymer is a polyolefin having a relatively high weight-average molecular weight methacrylate polymer grafted thereto. The graft copolymer is formed by dissolving or swelling a non-polar polyolefin in an inert hydrocarbon solvent, heating to dissolve the polyolefin, and while stirring the mixture, adding a methacrylate monomer, together with an initiator to produce a constant, low concentration of radicals, to form a graft copolymer with a high molecular weight polymer chain covalently bonded or grafted to the polyolefin backbone. The graft copolymer can be separated from the solvent, isolated by volatilizing the solvent, for example in a devolatilizing extruder, and extruded into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a polyolefin matrix. The blend exhibits improved physical properties in the melt, upon cooling, and in the solid state, and is useful in cast and oriented films, solid extruded rod and profile, foamed rod, profile and sheet, blown bottles and the like. The graft copolymer further improves compatibility in a wide range of polymer blends.
