Granted: 1991-03-05
Abstract: ABSTRACT             A heating stand for supporting an item which is to be heated in a microwave oven.  The stand comprises a boxboard blank having a microwave intereactive layer of material on its upper face.  The interactive layer extends continuously between first oppositely disposed edges, and is spaced laterally inwardly from the second side edges thereof to from uncoated margins at each of the second edges of the blank.  The blank is creased to provide fold lines which define a platform panel, support leg panels and leg bracing panels.  The platform panel is proportioned to provide support for an article to be heated.  The support leg panels are foldable along their crease line to project downwardly from the platform in use to support the platform in an elevated position in a microwave oven.  The leg bracing panels are foldable along their crease line to project downwardly from the platform in use and are connectable to the support leg and the bracing panels each have a distal end remote from the support panel.  The distal ends of the support legs are formed from the uncoated margins of the blank so as to be inactive when subjected to microwave radiation.  The distal ends of the support legs project a substantial distance below the distal ends of the leg bracing panels when in the folded position to support the interactive platform and the interactive leg bracing panels in a spaced relationship with respect to the underlying support surface in use.

Title: Quality improvement of alcoholic liquors
Inventor: KAKIMOTO SHIGEYA
IPC: C12N9/80
Filed: 1987-10-07
Granted: 1992-12-22
Abstract: Abstract  of the Disclosure Alcoholic liquors containing carbamide are treated with the urease which has the optimal pH for the activity in an acid region, especially in the region of pH 2 to 5.  By such treatment, the carbamide can be completely decomposed and removed from the alcoholic liquors in a much smaller amount of urease and in a short time as compared with the conventional treatment according to a urease having the optimal pH in the neutral  to alkaline region.  This method is more advantageous from the viewpoint of practical use and the quality of the thus obtained alcoholic liquors are superior to that  obtained by the conventional treatment.

Patent CA-1281089-C (CA)
Inventor: INVERNIZZI CESARE G
IPC: H02G13/00
Filed: 1987-10-30
Granted: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE:           Around an insulating central core is arranged a first conductive component planned to put  to earth a lightning installation.  This first conductive component is composed of metallic wires spreading parallel to the axis of the whole.  An annular coating made of insulating material is arranged around the metallic wires and a second conductive component,  constituted by metallic wires is arranged around  this  intermediate  insulating coating. Metallic wires of this second component also spread parallel to the axis of the whole and they are joined so as to form a metallic shielding.  An outside protecting coating, made of insulating material,  wraps the set of wires of the second conductive component.   This arrangement of metallic wires reduces at least their ohmic resistance and their inductance, which improves the performances of the whole for suppressing of side-flashings.  A high voltage  terminal properly sized contains the upper part so that, when lightning strikes it, it will be injected in an electrically hermetic system.
Patent CA-1337456-C (CA)
Title: Method of smelting metal oxide material
Inventor: WARNER NOEL ALFRED
IPC: C22B7/02
Filed: 1987-11-05
Granted: 1995-10-31
Abstract: Smelting reduction of metallic oxide material, eg. pelletized iron oxide ore or iron oxide ore fines is effected by contacting such material with a circulating molten carrier material, eg. molten iron in the case of iron oxide smelting, in a furnace, and by introducing a carbonaceous reductant eg. coal into the carrier material.  The reductant converts the metal oxide to metal in a smelting reduction zone.  Carbon monoxide thereby produced is combusted in a heating zone through which the carrier material passes to effect heat recovery.  Slag is removed from the carrier material surface before entering the heating zone.  A protective layer of molten material, eg. lead, which is substantially stationary is maintained below the circulating carrier material to inhibit erosion of the furnace hearth.  In other processes, deepsea manganese nodules are conjointly smelted with chalcopyrite in a circulating molten Cu-Ni-Co matte carrier whilst maintaining a protective layer of Cu-Ni-Co alloy below the matte; and high silica nickel laterite and limonitic ores are conjointly metallized and sulphided whilst being supported by a circulating molten nickel matte carrier, with controlled addition of carbon to cause a protective layer of ferronickel alloy containing carbon to be maintained below the matte carrier.

Title: Composite rotary drive member and method of its formation
Inventor: RAMPE JOHN F
IPC: F16H55/14
Filed: 1988-05-20
Granted: 1992-04-07
Abstract: COMPOSITE ROTARY DRIVE MEMBER  AND METHOD OF ITS FORMATION                            Abstract A composite rotary drive member such as a gear, pulley or the like is formed from thermoplastics material that is molded in situ about one or more metal inserts.  A circumferentially extending drive formation of desired shape and size is defined by the molded plastics material, and is molded without a need for conventional measures to compensate for shrinkage.   The drive member is formed by first forming a composite preform member that has injection molded thermoplastics material with peripheral por-tions extending about one or more metal inserts.  A band-like ring of injection molded thermoplastics material is molded to extend contiguously and continuously about peripheral  surface portions  of  the  molded  composite  preform  member,  with  the plastics material of the band-like ring and of the composite preform member  uniting  to  form  a  single  plastics  structure.          Because the  configuration of the drive  surface is determined solely  by  the  molding  of  the  outer  band-like ring  of thermoplastics material,  and because the band-like ring is so thin that it encurs a negligible amount of shrinkage, wheels, gears, pulleys and the like of a very wide range of diameters and torque capacities  can be  formed  inexpensively  and  accurately without a need to compensate for shrinkage.

Abstract: ABSTRACT       In response  to  a  first outgoing message from a telephone answering device in an original language, such as English, if a calling party from a country speaks in doubt  or  he  cannot  answer  it  quickly,  his  voice  is analyzed to determine what language it is in order to send him a second outgoing message in his own language, or else a second outgoing message in the original language is sent out promptly to prevent the calling party from hanging up. The foreign calling party thus can understand the second outgoing message  and  leave  his message on an incoming message tape.  It is possible to use the present invention not only in a telephone answering device, but also in a general banking system or in question and answer telephone equipment.
