Patent CA-2147732-A1 (CA)
Title: Photographic Printing Apparatus
Inventor: YAMAMOTO YUJI
IPC: G03B9/02
Filed: 1995-04-24
Abstract: A photographic printing apparatus includes a lens unit and a lens mount which are joined to each other in a separable manner.  The lens mount includes therein a drive motor and a drive force transmitting mechanism to adjust the focal distance and aperture of the lens unit.  A plurality of lens units having different focal distances are provided, from which a lens unit suitable for a printing magnification is automatically selected for printing.  Each lens unit is provided with external connection members which are connected to an aperture adjusting mechanism and the focal distance adjusting mechanism of the lens unit. The lens mount to which the lens unit is attached is provided with members which are engaged with the external connection members of the lens unit to displace them.  The displacement of these members is effected by motors provided on the lens mount.  With this structure, the cost of lens units can be reduced, and the efficiency of the printing operation can be increased.

Title: Flavoured low fat food products
Inventor: BOT DAVID SIMON MARIA
IPC: A23L27/20
Filed: 1993-10-11
Abstract: Flavoured food products which contain not more than 4 wt.% fat and at least 50 wt.% water and which produce a taste impact which is comparable to that of equivalent products containing a higher fat content. The concentration of some of the flavouring substances, diacetyl and at least one of the substances 5-decanolide and 5-dodecanolide, deviate very much from their levels normally applied in higher fat food products, which are well above 2 ppm. The food products encompassed by the present invention contain flavouring substances. In contrast to the conventional high fat products, the food products according to the invention are flavoured with only 0.02-2 ppm 5-decanolide and/or from 0.01-1 ppm 5-dodecanolide; and 0.5-40 ppm diacetyl.
Patent CA-2149764-A1 (CA)
Inventor: DELLA-CIOPPA GUY RICHARD
IPC: C12N9/02
Filed: 1993-11-22
Abstract: A process for the in vitro production of chemically modified polyphenolic polymer (PPP). First, stable, highly active extracellular tyrosinase is produced from genetically transformed microorganism such as Srrepromyces antibioticus. The tyrosinase is then incubated with a reaction substrate such as 1-tyrosine, hydrolyzed protein, or an oligopeptidc in combination with 1-tyrosine. The ratio of the oligopeptide/tyrosine combination as well as variation in the concentration of tyrosinase can be used to modify the color, the molecular size, and the spectral absorbance properties of the PPP produced.  Alternatively, or additionally, oxidants such as hydrogen peroxide or hypachlorite can be used to modify the color of the PPP, regardless of the method used to produce the PPP, and the PPP can subsequently be fractionated using molecular weight cut-off ultrafiltration. Organic solvents can also be used in the method of making PPP to produce PPPs having variable but reproducible physical properties.

Title: Apparatus for forming adobe blocks
Inventor: DOMAZET MICHAEL
IPC: B29C43/04
Filed: 1996-07-26
Abstract: A rotating Carrousel having four mould cavities equally spaced at ninety degrees from each other. The moulds are open vertically to the sky and in the opposite direction. The moulds are on the same pitch circle from the center of the axis. The rotary table "carrousel" is positively locked at each ninety degree turn. When the table is locked in position each station is in its position. The hopper containing the pre granulated soil is mounted stationary above the number one station. The hopper is fed by a screw conveyor from a hammer mill which breaks up the dug out soil into a uniform granulate. This is most important for the manufacture of high quality adobe bricks. When the hopper has filled the mould cavity the carousel is turned ninety degrees and the filling process is repeated, at the same time the ram at number two station compresses the soil into a high density adobe block. On a further ninety degree turn both operations are repeated, and at the same time at the number three station, a hydraulically operated ram ejects the completed adobe block. The carousel is mounted on a heavy frame suitable to sustain the hydraulic forces of the compression and ejecting rams.

Abstract: L'utilisation d'une formulation contenant une résine pouvant être mise en dispersion dans l'eau permet d'accroître les possibilités d'application de revêtements, et d'améliorer en particulier leur résistance à la formation de cloques. Cette résine comprend le produit de la réaction de copolymérisation de monomères vinyliques obtenus par addition, tels qu'un monomère renfermant un groupe acide, un monomère de N-(alcoxyméthyl)acrylamide ou de N-(alcoxyméthyl)méthacrylamide et au moins un autre monomère vinylique. La réaction a lieu en présence d'un solvant contenant un polyol, les groupes OH de la molécule de polyol présentant une réactivité inégale. Le copolymère peut être mélangé à une résine époxy modifiée avec une amine afin de former une composition de revêtement. Des résultats similaires peuvent être obtenus avec une formulation de revêtement comprenant une résine pouvant être mise en dispersion dans l'eau, ladite résine contenant le produit de la réaction de copolymérisation par addition de monomères vinyliques, tels qu'un monomère renfermant un groupe acide, et au moins un autre monomère vinylique mélangé à une résine modifiée avec une amine. Les groupes acides présents dans le copolymère de vinyle obtenu par addition n'ont été que partiellement neutralisés lors de la mise en dispersion aqueuse. Des résines époxy défonctionnalisées avec une amine, utilisées dans des formulations de revêtements, améliorent la résistance à la formation de voile et de taches si les rapports de réaction entre équivalents groupe époxy et équivalents amine primaire ou ammoniac sont proches de 1:1.

Filed: 1996-09-10
Abstract: In a method of forming an amorphous carbon thin film with a plasma chemical vapor deposition method, at least one of a hydrocarbon gas and a carbon fluoride gas is supplied in a reaction chamber as a material gas.  By applying a high voltage between two electrodes, a plasma is generated in the reaction chamber using the supplied material gas.  As a result, an amorphous carbon thin film is deposited on a substrate while preventing deposition of an adhesion on an inner wall of the reaction chamber.  In order to prevent the adhesion from depositing on the inner wall, at least a part of the inner wall of the reaction chamber is heated to a predetermined temperature or above such that a adhesion coefficient of the adhesion is 0.  The predetermined temperature is 200 °C.  The reaction chamber is desirably made from a material having a thermal conductivity sufficient to unify a temperature of the whole of the reaction chamber.        Alternatively, in order to prevent the adhesion from depositing on the inner wall, a bias voltage such as one of DC bias, a high frequency bias and a high frequency bais imposed on a DC bias is applied to the electrically conductive reaction chamber.
