Title: Polyurethane resin and utilization thereof
Inventor: OZAKI SATOSHI
IPC: C08G18/40
Filed: 1990-05-04
Abstract: ABSTRACT       The present invention relates to a novel polyurethane resin, a foam prepared from the resin, a preparation process of the foam, and preparation process of a rigid polyurethane foam composite having a face material.  The primary object of the present invention is to provide a rigid polyurethane foam and a rigid polyurethane foam composite fitted with a face material which are prepared by using a hydrochlorofluorocarbon foaming agent having very low public hazards such as ozone layer destruction and green house phenomenon of the earth.      The above object can be achieved by using a combination of a polyether polyol initiated from a phenol resin with an alkanolamine or an aliphatic polyhydroxy compound in the production of rigid polyurethane foams.      Foams thus obtained have equivalent properties to those of foams obtained by using chlorofluorocarbons(CFC) which are conventional foaming agents.
Patent CA-2016279-A1 (CA)
Inventor: BRANT ANTHONY W
IPC: E04D13/068
Filed: 1990-05-08
Abstract: An eavestrough fitting according to the present invention comprises a moulded plastic member having an improved gasket secured thereto. The gasket has at least two ribs extending across the member and up the sides thereof with the ribs sized to form a seal with an appropriately shaped eavestrough inserted within the fitting. The moulded plastic member has a generally flat base connected to outwardly angled sidewalls which terminate in a short vertical section. The gasket conforms to the shape of the moulded plastic member and includes a raised land interior to the ribs. This raised land limits the extent of deformation of the ribs while providing a resilient base for supporting the eavestrough section within the fitting. The raised land allows the eavestrough section interior to the ribs to be in contact with the land and the lower surface of the eavestrough such that grit and other debris has less of a tendency to become lodged beneath the eavestrough section.

IPC: B31F1/12
Filed: 1990-07-25
Abstract: ABSTRACT OF THE DISCLOSURE:     A method is disclosed of manufacturing a Z-directional compressibility gradient in a web of paper.  The method comprises the steps of coating the peripheral surface of a roll with a film of plasticizer.  An offset roll disposed adjacent to the roll is rotated such that the roll and the offset roll define therebetween a transfer nip so that a film of the plasticizer is transferred to the  offset roll.  The web is moved past the offset roll such that the web contacts the offset roll downstream relative to the transfer nip so that the film of the plasticizer is offset onto the web.  The web is then passed with the offset coating of plasticizer through a calendering nip such that between the offset coating of the web and the subsequent calendering of the web with the offset coating, the plasticizer is permitted to uniformly and controllably penetrate into the web such that the Z-directional compressibility of the web is controlled prior to the web extending through the calendering nip.

Title: Faulted circuit detector having isolated indicator
Inventor: DUNK MICHAEL P
IPC: G01R31/58
Filed: 1991-05-06
Abstract: ABSTRACT      A faulted circuit detector having an electrically isolated and remotely positioned indicator detects fault currents in a monitored conductor.  When a fault of a predetermined magnitude is detected, a light pulse is transmitted from the detector to the indicator via a fiber optic cable where, upon receipt, the pulse is converted to an electrical pulse causing the indicator to  indicate  a  "fault"  state.    A  reset  circuit  within  the indicator  resets  the  indicator  at  regular  intervals  to  the "normal"  state as long as a predetermined minimum voltage is present  on the monitored conductor.   A test circuit is also provided to allow service personnel to field test the device with the monitored conductor in an energized state.
