Title: Manufacturing method of structural parts for wearing products
Inventor: ECHI KOZO
IPC: A61F13/472
Filed: 1990-04-20
Abstract: A manufacturing method of structural parts for wearing products is described which allows partial webs having one concavoconvex edge to be attached to other parts of the product in a high speed process of manufacturing these vearing products. A concavoconvex cutting line (33) is applied in the longitudinal direction of a first web (30) to form first and second partial webs (30a,30b,130a,130b). The first partial web (30a,130a) is offset with respect to the second partial web (30b,130b) in the longitudinal direction thereof by a prescribed interval, so that the concave edges and the convex edges (33a,33b) of the first and the second partial webs (30a,30b,130a,130b) are positioned opposite and aligned to each other respectively. Thereafter the wearing products are manufactured with these partial webs arranged on the outsides thereof.

Title: Production of higher quality maple syrup
Inventor: PAQUETTE YVON A
IPC: C13B25/00
Filed: 1990-05-29
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.

Patent CA-2030578-A1 (CA)
Inventor: LYNCH GREGORY A
IPC: F23N5/20
Filed: 1990-11-22
Abstract: The present invention discloses a method of compensating for a restricted intake in a two stage furnace.  The furnace includes low and high pressure switches for determining if sufficient air is present to support low and high combustion.  When the furnace operates at high combustion, the state of the high pressure switch is monitored to determine if the high pressure switch has changed state for a predetermined amount of time such as 15 seconds.  The inducer fan is switched to low when insufficient air for high combustion has been indicated for such a predetermined time.  If the state of the low pressure switch indicates that insufficient air is available for low combustion, then the inducer is turned on high.

IPC: H04N5/262
Filed: 1991-03-28
Abstract: VIDEO SPECIAL EFFECTS SYSTEM                        ABSTRACT OF THE DISCLOSURE     A patch-driven video 3D special effects system constructs an output display of a desired three-dimensional shape with real-time video picture information displayed on the surface of the shape by dividing a video source plane into a plurality of polygonal patches and manipulating said patches in three dimensions to create the shape.  The special effects system is controlled by a keyframing control system in which a small number of selected parameters are used to define several general purpose 3D shapes.  These parameters are then specified in each keyframe.  By varying the selected parameters, the general purpose object can be reshaped into a number of familiar shapes such as cubes, cones, etc.  A pre-defined program converts the selected parameters into patch shapes and vertice positions which are used by the video special effects hardware to actually create the images.

Title: Subtractive color hot melt ink reflection images on opaque substrates
Inventor: HOISINGTON PAUL A
IPC: G01D15/16
Filed: 1991-06-20
Abstract: In the particular embodiments of the invention described in the specification, an opaque subtractive color ink reflection print having improved color pu-rity resulting from reduced frosting and crystalliza-tion of the ink layers is prepared by reheating the ink image to a temperature above the melting point of at least one of the inks and then quenching the image by cooling it at a rate of at least 50°C per second. In one embodiment, the ink image is produced by an ink jet head (10) applied to a substrate (14) supported on a platen (15) maintained at least 20°C below the melt-ing point of the inks to inhibit spreading of the inks into the substrate, and the image is thereafter heated by a heater (28) to a temperature at least 20°C above the melting point of at least one of the inks for a period of 3 to 5 seconds and then quenched by a quenching platen (32) at a rate of 500°C per second to produce an image having less than 20% light loss re-sulting from scattering of light by frosting and crys-tallization of the ink in the layers.
