Abstract: A film structure demonstrates a good non-tackiness and good adhesiveness properties  for a high temperature cooking apparatus.  A ceramic layer including poly-titano-carbosilane is formed on a substrate forming a cooking surface or  an  inner  surface  of  a heating chamber  of  the  high temperature cooking apparatus.   A non-tacky resin  layer including a fluororesin is formed on the ceramic layer.  At an interface between the ceramic layer and the non-tacky resin layer,  the  proportion of  poly-titano-carbosilane  to  the fluororesin changes successively in a vertical direction.  In this film structure, the ceramic layer and the non-tacky resin layer are strongly bonded together with a good adhesiveness. Since the ceramic layer includes poly-titano-carbosilane as its principal component,  it is highly resistive to heat. Further,  the film has an enhanced resisting property to corrosiveness because of the presence of the non-tacky resin layer formed on the ceramic layer.

Abstract: A process for making a light color maple syrup from a water-containing sap. In a first step, the sap is boiled under normal pressure to evaporate part of the water contained therein in the form of steam, to form the maple syrup and to develop caramelized and sweet characteristics and give flavour and a tinted color to this maple syrup.      In a second step, the sap is heated at a temperature lower than the boiling temperature of the sap and atomized through an air circulating column to evaporate another part of the water contained therein. This second step which can be carried out before the first one, permits to concentrate the sap, to increase its sugar content and to avoid further caramelization thereof. The sap which is so obtained with an increased sugar content, may be recycled as long as necessary until a desired sugar concentration corresponding to a predetermined Brix number is reached.

Title: Conveyor belt dumping mechanism using horizontal idlers of varying lengths
Inventor: WILSON WILLIAM A
IPC: B65G47/84
Filed: 1990-06-04
Granted: 1993-08-17
Abstract: CONVEYOR BELT DUMPING MECHANISM USING HORIZONTAL IDLERS             OF VARYING LENGTHS         Inventor:         William A. Willson 83 Pheasant Drive Marietta, GA 30067 ABSTRACT   An  array of idlers supporting a conveyor  belt  except beneath   a  generally  crescent-shaped   section   opening outwardly to one side thereof. The array includes idlers of various  lengths  and orientations. Each of the  idlers  is disposed  perpendicularly  to the centerline of  the  belt.          Both   upstream  and  downstream  of  the   crescent-shaped section, pairs of idlers slope downwardly toward each other on  either side of the belt centerline. Where the  belt  is supported  by these pairs of idlers, it assumes  a  trough-like  configuration. Proximate the cresent-shaped  section, on  the  other hand, the idlers are unpaired and  disposed horizontally.  The  shortest of these  unpaired  idlers  is situated  to one side of the cresent-shaped section at  its greatest  transverse  width. On the other  side  but  still within  this  section,  the lip of the  belt is  virtually unsupported  forming a soft spot. This soft spot  is  sized and  situated  so that any burden carried by  the  conveyor tends  to  remain  on it unless  a  force  is  specifically applied  to  deflect objects within the  burden  laterally.     When  force  is applied which causes a  sufficiently  large object  to  move  transversely across the  soft  spot,  the crescent-shaped section acts as a chute. In such instances, the belt lip sags downwardly, becoming the  lowest part  of the  belt  and  allowing the deflected   objects  to  slide easily off the belt. As a result, less force is required to push objects off the side of the conveyor than would other-wise be the case, and the life of the belt is extended.

Title: Method and apparatus for molding a threaded product
Inventor: WILLIAMS BRIAN L
IPC: B29D1/00
Filed: 1991-11-05
Granted: 1994-10-04
Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for molding a product having internal threads includes a threaded mold core and a device for rotating the mold core about the axis of its threads and for axially withdrawing the core from the mold at a rate that is related to the rate of rotation, according to the pitch of the threads.  This is accomplished by a cam, which is rotated in synchronism with the device that rotates the core, and a follower for displacing the core as the cam is rotated.  The cam follower is fixed with respect to the mold.  The cam and threaded core are positioned on a carrier, along with the device for rotating the core, such that rotation of the cam displaces the carrier away from the mold.  The core is inserted into the mold, prior to the molding process, by displacing the carrier toward the mold without rotating the core.  In one embodiment, the cam is rotated by a uni-directional motor such that resetting of the cam after the core is withdrawn is accomplished by forward indexing of the cam a small amount to a zero position.
