Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a process for the production of hydrophilic filaments or fibres having a sheath/core structure, a porosity of at least 10 % and a water retention capacity of at least 10 % and having a fibre swelling factor which is lower than the water retention capacity.  The process is carried out by spinning a solution of a fibre forming synthetic polymer, especially an acrylonitrile polymer by the dry jet wet-spinning method wherein immediately on leaving the spinning jet and prior to coagulation in the precipitation bath the filaments or fibres are contacted with steam or with the vapor of another coagulation initiating liquid which initiates coagulation of the as yet unsolidified filaments, the filaments then being fully coagulated in a precipitation bath.  The dry jet wet spinning process provides an highly porous and hydrophilic fibre by means of the steam or vapor of another liquid which is used as a first precipitation medium.

Abstract: ABSTRACT OF THE DISCLOSURE        A razor knife has an elongated housing formed of a front housing part and a rear housing part and having a longitudinally extending guide.  The rear housing part is backwardly separable from the front housing part and carries a blade holder which has a seat for a razor blade and an actuator button exposed at a slot formed in the front housing part.  This holder is displace-able by sliding of the actuator button from a back position with the blade wholly enclosed by the housing into a front position with a portion of the blade projecting forwardly from the housing. A tension spring inside the insert or back housing part continu-ously urges the holder into the back position.  Interengaging formations on the operating button and the housing, however, allow the blade to be held in the outer position so long as a slight inward force is exerted on the slidable actuator button.

The resin is formed by reacting an excess of a suitable aliphatic diisocyanate with a suitable mixture of polyoxypropylene diols and triols and a hindered piperidine type UV stabilizer in the presence of an organotin catalyst.  The product urethane resin having the stabilizer reacted into its molecular structure is formulated with color producing pigments, metallic flakes and a suitable solvent to produce a composition having a nonvolatiles content of 60 to 70 weight percent.  The composition is spray applied to a substrate and moisture cured to provide a decorative topcoat wherein the flakes lie at varying depths and are oriented substantially parallel to the topcoat surface.  The topcoat with the desired flake orientation displays a high degree of geometric metamerism comparable to metallic acrylic lacquer topcoats applied at a substantially lower solids content.

Abstract: IMPROVED REGULATION CIRCUIT     ABSTRACT OF THE DISCLOSURE      A regulation circuit for providing timing gate signals to the dc power section of a power supply, the regulation circuit utilizing phase angle conduction of a programmable unijunction transistor.  The conduction angle is determined by the occurrence of the cycles of the ac source voltage unless earlier conduction is determined by the sensed dc voltage.  Early conduction occurs when the control voltage to the PUT is allowed to build up beyond a predetermined level when the sensed dc voltage is low.  When the sensed dc voltage is high, an electronic switch closes to discharge a storage element to prevent control voltage build up and, hence, early conduction.  When there is an ac source voltage outage, a diode connected to the control voltage output conducts to keep the control voltage to zero and hence closing of the electronic switch to prevent undue regulation of the power section output at such times and to permit storage capacitors therein to maintain a dc output until source voltage is reestablished.  Soft start elements in the form of long time constant components ensure against the application of peaked voltages during initial start up and in the presence of power surges.

Abstract: ABSTRACT OF THE DISCLOSURE     A pipe coupling of the type having two flanged type pipe end portions surrounded by a sleeve and held together by lever-operated half-shells whose radially inwardly directed flanges engage axially outside shoulders of radial protrusions, one of such protrusions being on a retainer  ring whose small-diameter portion is inserted in one end portion of the sleeve, the other protrusion being on the exterior of the sleeve.  In one embodiment, two rings are provided, one at each end of the coupling, whereby a single shell may engage only protrusions on the respective rings, thus eliminating the need for the radial outward protrusions on the sleeve.  The invention provides axial and radial clearance between the components, namely between the retainer ring and the respective pipe end, and between the ring and the engaged end of the sleeve, to improve accommodation within the coupling of both angular and axial displacement between the pipe end portions, when the coupling is in a closed state, thus considerably broadening the field of application of the coupling.

Abstract: A B S T R A C T     An improved degerminating process wherein the grain kernels are crushed from the thin edges toward the center while avoiding crushing of the relatively flat side surfaces.  The crushing force fractures the endosperm under and around the germ and squeezes the germ away from the  endosperm in a whole condition.  A machine for carrying out the degermination includes relatively rotating discs having corrugations in their facing surfaces in which the kernels are caught and crushed from the thin edges toward the center.  An alternative degerminator machine includes a single rotating disc having curved  guide vanes on its upper surface for guiding the kernels as they are propelled outwardly by centrifugal  force.  The vanes orient each kernel with its top or bottom edge in position to impinge upon flat impact surfaces which results in a crushing force applied from the thin edge toward the center of the kernel.  Milling processes employing the improved method of degermination utilize, at the front end of the mill, rollers with fine corrugations which are normally used only at the end of a long succession of rollers in a conventional differential milling operation.  The rollers are adjusted to minimize penetration of the germ to thereby maintain it in a whole condition and produce high quality fines that remain in the prime product streams.

Abstract: Gerry Vander Vaart HEAT-AUGMENTED HEAT EXCHANGER     ABSTRACT OF THE DISCLOSURE       A heating system of the heat pump type is disclosed in which the outside coil, employed to reject heat in air conditioning mode ox to absorb heat in heating mode, is supplied with heat independently of that provided by ambient air when the efficiency of the system falls off due to low ambient air temperature.  The amount of heat thus supplied is controlled to increase the efficiency of the system sufficiently to produce a significant net decrease in operating cost.  In a conventional system, the outside air coil-cooling face is turned off and augmenting heat is supplied to the coil when the ambient air temperature is moderate (e.g., 32-38°F) for the system, and the augmenting heat is supplied at a rate which is at least sufficient to restore the efficiency of the system to that inherent with a much higher ambient air temperature.  At the same time, the outside coil temperature is monitored and the augmenting heat is temporarily discontinued when the coil temperature reaches a selected value (e.g., 70°F).
