Inventor: EWEN JAMES H
IPC: C08G18/00
Filed: 1986-09-24
Abstract: Reaction injection molded polyurea elastomers are disclosed that are derived from the reaction of (1) an aromatic polyisocyanate; (2) primary or secondary amine terminated polyethers; and (3) a novel aromatic amine extender combination comprising (a) an aromatic diamine having at least one of the positions ortho to each amine group substituted by a lower alkyl group and (b) a polymethylene polyphenylamine. The blending of (2) and (3) affords novel polyamine blends which are useful for preparing the polyurea elastomers of this invention.The use of the polymethylene polyphenyl amine com­ponent allows for the retention of the good physical properties of the prior art polyureas while at the same time effecting a cost reduction in the preparation of this useful class of polymers.

Abstract: A method and apparatus for integral control of a dependent variable in a system having at least two independent variables which influence the dependent variable is disclosed. A difference signal indicative of the difference between the sensed dependent variable and a reference is integrated and provided to a hysteresis transfer function. The output of the transfer function is subtracted from the integrated difference signal and the resulting signal is used to control an independent variable which thereby influences the dependent variable only for small magnitude signal variations in the integrated signal. The integrated signal is used to control another independent variable for large magnitude signal variations in the integrated signal. The other independent variable is typically only capable of influencing the dependent variable for large magnitude signal variations.

Abstract: A heat exchanger 36 for cooling an array of electric circuit chips 22 disposed on a common substrate 24 is formed as a flexible sheet 38 of thermally conducting material with upstanding fins 40 for transference of heat from the chips to a coolant flowing through the fins. The sheet may be provided with corrugations 44 set between sites of the chips for improved flexibility to accommodate individual orientations of the chips. The sheet is sufficiently large to cover an array of chips and is secured adheringly, as by use of a thermally conductive grease, to the chips. The sheet hermetically seals the chips from contamination by the coolant. The heat exchanger may be fabricated of copper with a nickel coating, wherein the copper provides the heat conduction and the nickel protects the copper from a corrosive coolant such as water. The finned sheet may be efficiently fabricated by processes analogous to those used to make printed circuits. In one embodiment of the heat exchanger, the fin thickness, the fin spacing and the sheet thickness are all approximately equal, a typical sheet thickness being approximately 0.05 mm.

Abstract: The invention relates to an electric converter operating on the principle of an isolating transformer or flux converter, in particular a switching power supply and/or line transformer for a television set, having an essentially closed, multi-limbed core in which one or more permanent magnets are inserted outside points surrounded by coils in the path of the core. The permanent magnets and, if required, an air gap, are of such dimensions that, outside the near field, the orders of magnitude of scatter fields of comparable converters having no permanent magnets are not significantly exceeded. The permanent magnets preferably have a height of approximately 0.3 mm, the air gap having a height of approximately 1.3 mm. A nominal power increase of approximately 50 % is achieved compared with the said converters.

Abstract: Seasoning composition is produced with a method,, which comprises coating fine particles of sparlingly water-­soluble 5′-ribonucleotides having a total water content of 12 to 20 weight % and a particle diameter not exceeding about 150 µm with an oil/fat and/or a wax melting at a between about 55°C to about 90°C. The thus obtained seasoning composition causes very little cracks or gaps on the surface of coated particles even after storage for a long time. Accordingly this composition is applicable with advantage to foods because of good protection from degradation of 5′-ribonucleotides due to phosphatase.

Abstract: This invention relates to a manifold housing for a valve gated single cavity injection molding system. The heated manifold housing (14) has a dome portion (40) and a base portion (38) which is secured to a heated nozzle (10) with aligned central bores (22, 42) through which the valve pin (44) extends. Hydraulic actuating mechanism is mounted inside the manifold housing to reciprocate the valve pin (44) between open and closed positions. The melt duct (52) in the manifold branches from a central inlet (20) into two separate arms (54, 56) with smoothly curved bends which extend to join the central bore (42) on opposite sides of the valve pin (44). Providing two streams of melt which meet at the valve pin avoids the problem of streaking and slow melt flow on one side of the valve pin.

Abstract: Before beginning a prior art imaging sequence, at first parts producing artifact are excited by applying a high frequency magnetic field thereto in a frequency band, which includes the parts emitting artifact and doesn't include a desired slice plane (a in Fig. 6, a in Fig. 8). Next, the phase of the excited spin is extremely rotated by applying at least one of gradient magnetic fields G x , G y , G z  (b in Fig. 6, b in Fig. 8). When the prior art imaging sequence is effected there­after (c-f in Fig. 6, c in Fig. 8), the produced artifact is imaged as a high spatial frequency component of an object body to be examined. Since a usual object body to be examined contains many low spatial frequency components and the power of high spatial frequency components is extremely small, it becomes possible to reduce the artifact in such an extent that it cannot be practically recognized.

Abstract: panoramic display system for an aircraft comprising a display screen and line generation means for generating a line image on the display screen. The position of the line image on the display screen corresponds to the position of a projection of an artifact external to the aircraft onto an imaginary window to an eye point within the aircraft. The eye point is positioned on the opposite side of the window from the artifact. The line image may be generated by determining the position of a great circle on a sphere having its center at the eye point, such that the position of the great circle corresponds to the artifact projected onto the sphere to the eye point. The position of the line image on the display screen corresponds to the position of the great circle on the sphere.The display system may comprise a plurality of display screens positioned adjacent to one another such that each can be viewed from a single viewing point. Partial line images are generated on each display screen such that the position of each partial line image corresponds to the position of the projection of the artifact onto a window portion to the eye point. The eye point is common to all window portions, and the spatial relationship of the window portions with respect to one another is congruent with the spatial re- lationsship of the display screens with respect to one another.

Abstract: An apparatus for comminuting waste material such as waste plastic sheet material, into progressively smaller pieces until a desired size is reached that may be recycled. The apparatus has a set of slowly rotating, intermeshing scissor rolls for receiving the waste material and shearing the material into smaller pieces. A paddle wheel conveyor receives the smaller pieces from the scissor rolls and moves the smaller pieces over a screen with the undersized smaller pieces passing through the screen defining the desired reduced size. The oversized smaller pieces that do not pass through the screen are reprocessed back to the scissor rolls by the paddle wheel conveyor. A vacuum pump draws air through the apparatus and the screen to facilitate the separation on the screen and entrains the undersized pieces in an air stream to convey the pieces from the apparatus.
