Filed: 1990-03-14
Abstract: PLASTIC TOOLING              WITH COMPRESSION ADJUSTMENT                 Abstract of the Disclosure Epoxy tooling which inherently expands and contracts with temperature changes for making parts of metal or plastic has elongated rods extending through guide tubes within the tooling and compression washers or plates on opposite sides thereof.  These compression devices for strengthening the tool can be selectively adjusted toward and away from one another using nuts threaded on the rods for varying the compression load on the tooling in accordance with varying tool operating loads, working temperatures and amounts of expansion or contraction.  Epoxy tools for molding plastics are heated and expended to a working temperature and then compressively loaded in selected areas prior to molding operations to prevent tool stress cracking or epoxy tools for metal stamping are compressively loaded and supported in selected areas of high tensile stress and operated at room temperatures for high load metal stamping without fracture.

Patent CA-2021602-A1 (CA)
Title: Method for improving speech quality in code excited linear predictive speech coding
Inventor: ZINSER RICHARD L
IPC: G10L19/00
Filed: 1990-07-19
Abstract: By reconciling differences between the estimator and the filter of a code excited linear predictive (CELP) voice coder, higher quality is achieved in the output speech. The pulse amplitudes and pitch tap gain are solved for simultaneously to minimize the estimator bias in the CELP excitation. Increased signal to noise ratio is accomplished by modifying the pitch predictor such that the pitch synthesis filter accurately reflects the estimation procedure used to find the pitch tap gain, and by improving the excitation analysis technique such that the pitch predictor tap gain and codeword gain are soled for simultaneously, rather than sequentially. These modifications do not result in an increased transmission rate or significant increase in complexity of the CELP coding algorithm.

Abstract: 2. PRÉCIS. Les séchoirs déjà connus ne comportent pas les avantages d'être à la fois muraux et avec des baguettes à linge escamotables facilitant le rangement et l'occupation de l'espace. La présent invention est composée de trois catégories d'items: 1- Une fixation murale à être installée au mur; 11- Un bloc de soutien pour accrocher les baguettes à linge qui sont maintenues au mur par la fixation; 111- Des baguettes à linge spécialement conçues pour faciliter le séchage. Ces trois composantes s'intègrent entre elles et forment le séchoir à linge mural escamotable. Les baguettes à linge sont amovibles et peuvent être installées manuellement par l'utilisateur. Elles peuvent prendre deux positions: elles se bloquent horizontalement lors de l'utilisation et elles se décrochent pour prendre la position verticale lors du rangement le long du mur. La disposition horizontale, en éventail, des baguettes à partir du mur permet d'offrir un meilleur espace d'étalement pour les objets à sécher. Lorsque les baguettes sont repliées, elles sont groupées le long du mur et elles accaparent peu d'espace pour le rangement. L'utilisateur peut employer un ou tous les supports selon les besoins. La versatilité que permet l'emploi du séchoir lui confère un attrait nouveau au point de vue de son utilisation, de sa sécurité d'emploi et de son efficacité pour le séchage du linge.

IPC: B01J19/08
Filed: 1991-06-04
Abstract: ABSTRACT OF THE DISCLOSURE              The   apparatus,  for   irradiating   an ultraviolet light-curable liquid coating applied on a floor, comprises a wheeled body and an irradiation module.  This irradiation module generates ultraviolet light projected onto the floor to cure and harden the liquid coating.   It is mounted on the wheeled body through a mechanism structured to move it laterally in either direction in order to irradiate the ultraviolet light-curable  coating  applied  on  floor  portions difficult to reach.  A casing contains an ultraviolet light-generating lamp and a reflector,  and another mechanism tilts this casing in order to project the ultraviolet  light on  floor portions of which the access is difficult.  The wheeled body is supported by a set of four swivel casters and can therefore be easily displaced in any direction.

Title: Production of low-chloride alkali metal phosphates
Inventor: NGUYEN KIM D
IPC: C01B25/30
Filed: 1991-08-26
Abstract: Potassium  phosphate  useful  as  a  low-chloride content fertilizer is prepared by reacting phosphoric acid,  commercial or technical grade, with fertilizer-grade potassium chloride (Muriate of Potash, 60-63% K2O) at a reaction temperature of about 130° to about 200°C and a mole ratio of phosphorus to potassium of at least about 1.3:1.  The vaporization of hydrogen chloride from the reaction mixture is effected by a novel technique combining  air followed  by  steam  stripping.    The reaction product is used to produce various types as well as grades of fertilizers.   The procedure may be used to form sodium phosphate in analogous manner from sodium  chloride,  which  then  may  be  converted  to trisodium phosphate or sodium tripolyphosphate.   The potassium  phosphate  may  be  converted  to  potassium pyrophosphate by neutralization with potassium hydroxide followed by calcination.
