Patent CA-2109751-A1 (CA)
Inventor: WILSON PHILLIP E
IPC: G01N21/85
Filed: 1993-11-23
Abstract: The concentration of a colorant in a stream of molten polymer is measured by inserting a probe adjacent to the stream.  The probe has integral therein collection means and illumination means. The steam is illuminated with the illumination means to cause electromagnetic radiation to be reflected from the molten polymer.  The electromagnetic reflectance is collected, transmitted to a measurement device remote from the molten  stream and quantified as a function of the concentration of the colorant.

Abstract: A method for screen printing of paste, such as solder paste, onto a board, such as a printed circuit board.  The paste (2) is fed into a chamber (1) of a dispenser (A) from a paste supply device connected to the dispenser.

Abstract: A method of manufacturing a three-dimensional fabric of the type which may be used in absorbent garments, dressings or the like involves the use of an apertured collector element which has a predetermined three-dimensional shape. The method involves positioning material adjacent to one side of the apertured collector element and developing a pressure differential between the one side of the apertured collector element and a second, opposite side to force the fabric material against the apertured collector element. The material, which has conformed to the shape of the collector element, is then solidified into its intended three--dimensional shape.

Title: Thin film transducer with coil guard segment
Inventor: LIN FONG-JEI
IPC: G11B5/31
Filed: 1994-02-10
Abstract: A thin film transducer has a top pole formed by ion beam milling, a bottom pole and a multi-turn coil inductively coupled to the poles. The multi-turn coil has an outer dummy turn which is electrically disconnected from the remaining coil segments so that the external electrical connection to the outer portion of the coil is made to an inner segment. During fabrication of the top pole, any damage to the previously formed coil by ion beam milling occurs to the dummy turn, rather than the inner segment to which electrical connection is made. A thin film transformer is provided with the same dummy turn structure.

Patent CA-2116914-A1 (CA)
Inventor: METCALF BENJAMIN J
IPC: C12P21/00
Filed: 1994-03-03
Abstract: The invention pertains to a novel method and plasmid system for producing abundant quantities of CRM197 protein, diphtheria toxin or other CRM proteins related to diphtheria toxin, as well as to microorganisms transformed with the novel plasmid. A particularly preferred DNA plasmid, designated pPX 3511, that combines the gene for CRM197 from the nontoxigenic betaphage and the plasmid pNG2-22 is described. The novel plasmid system is capable of transforming strains of Corynebacterium diphtheriae into strains which are capable of expressing high levels of the CRM197 protein without the use of multiple lysogens. The invention provides an elegant means for increasing protein production without having to manipulate the expression vector, such as by increasing the promoter strength, or removing the promoter from iron regulation.

Inventor: GAA KARL
IPC: C08K5/35
Filed: 1995-02-17
Abstract: The invention relates to a process for the preparation of polyalkyl-1-oxa-diazaspirodecane compounds, which can be used as highly active light stabilizers for polymers. The reaction is carried out in an inert organic solvent in the presence of solid alkali metal hydroxide or of the corresponding amount of a mixture of solid alkali metal hydroxide and water as the sole catalyst. The process offers  the advantage  that,  by changing the  reaction procedure in a multiphase system and avoiding the use of a phase  transfer catalyst,  equally good results  are achieved with  regard  to  product  quality  and yield. Additionally, it is possible to reduce the reaction time from over 6 hours to 30 minutes.   This results in a considerable   rise   in   the   space-time   yield and consequently contributes, in addition, to an increase in the economy of the process of the invention.

Title: Anchoring device for unbrellas
Inventor: PLOURDE BERNARD
IPC: A45B11/00
Filed: 1995-02-21
Abstract: An anchoring device for anchoring a post into a ground surface made of granular material. The anchoring device is particularly well adapted to anchor a beach umbrella into the sand. The anchoring device has a sleeve section and an integrally extending insertion section. The sleeve section defines a post receiving channel adapted to receive the post. The insertion section has a conically tapering configuration. A pair of parallel insertion threads extends integrally from the outer surface of the insertion section and a portion of the sleeve section. The parallel threads facilitate the insertion into the sand and further stabilize the device. A locking sleeve extends integrally from the sleeve section adjacent its top end. The locking sleeve defines a threaded locking channel that emerges into the post receiving channel. A handle sleeve also extends integrally from the sleeve section. The handle sleeve is diametrically opposed to the locking sleeve. The handle sleeve defines a handle channel that also emerges into the post receiving channel. A locking-handle component having an "L"-shaped configuration and a threaded end section are adapted to be slidably inserted into the handle sleeve channel and threadaly inserted into the locking channel for respectively acting as a handle and releasably locking the post into the post receiving channel.

Title: Vapor-air steam engine
Inventor: GINTER J LYELL
IPC: F01K21/04
Filed: 1993-10-27
Abstract: A vapor-air steam engine is described which operates at high pressure and utilizes a working fluid consisting of a mixture of compressed uncombusted air components, fuel combustion products and steam.  In the new cycle described, working fluid is provided at constant pressure and temperatures. Combustion air is supplied adiabatically by one or more stages of compression.  Fuel is injected at pressure as needed. At least about 40 % to all of compressed air is burned. Inert liquid is injected at high pressure to produce steam and thus provide an inert high specific heat diluent vapor required for internal cooling of an internal combustion turbine or other type system. The use of extensive liquid injection inhibits the formation of pollutants, increases the efficiency and horsepower of an engine; and reduces specific fuel consumption.  The new cycle may also be operated open or closed;  in the latter case, the liquid may be recouped via condensation for regenerative reuse. When salt water is injected into the system potable water is recovered from the steam exiting the power turbine and sterile sea salt is recovered from the cumbustion chamber.
