Patent CA-1334512-C (CA)
Inventor: FLENO BENT
IPC: A23K/
Filed: 1988-04-15
Granted: 1995-02-21
Abstract: A yeast cell, preferably a mutant of Phaffis rhodozyma, which, when grown under conditions comprising an oxygen transfer rate of at least 30 mmoles/1/hour on Difco YM medium at 20-22°C for 5 days in 500 ml shake flasks with two baffles containing 50 ml of the medium and sub-jected to orbital shaking at 150 rpm, the inoculum being 100 µl of a four days old YM culture, produces the red pigment, astaxanthin, in an amount of at least 300 µg per g of yeast dry matter, typically at least 800 µg per g of yeast dry matter, determined by HPLC analysis using pure astaxanthin as a standard on a methanol extract of the yeast prepared by subjecting a suspension of 0.2 g of yeast dry matter in 20 ml of methanol to 5 x 1 minutes of disintegration at intervals of half a minute, the disintegration being performed at a temperature of at the most 20°C in a glass ball mill containing 15 g of glass balls having a diameter of 0.4 mm, the glass ball mill being provided with a cooling jacket with ice water. The amount of astaxanthin produced by the yeast cell, i.e. at least 300 and typically at least 800 µg per g of yeast dry matter, should be compared with the amounts of astaxanthin produced by known Phaffia rhodozyma strains which is at the most about 250 µg per g of yeast dry matter. The mutants of Phaffia rhodozyma may be obtained by conventional methods of mutation. The yeast cells are preferably cultivated by fed-batch fermentation which is performed under sufficient aeration, the fed-batch fermentation preferably comprising a growth phase and a subsequent growth-limited phase. Subsequent to the cultivation, the yeast cells may be subjected to e.g. rupturing and homogenization treatments, and the astaxanthin may optionally be extracted from the yeast cells. The yeast cells or the extracted astaxanthin may be used in animal feed, especially feed for anadromous fish such as salmon or trout, which when being fed with the astaxanthin-containing feed obtain an attractive red colour.

Title: Multipurpose chassis for commercial and special vehicles
Inventor: BAIKER WALTER
IPC: B62D21/18
Filed: 1988-04-28
Granted: 1992-02-04
Abstract: A B S T R A C T         For commercial and special vehicles, such as weapon carriers, mobile radar stations, mobile satellite control stations and mobile cranes, which must carry a very considerable weight, it is necessary to use very robust chassis.        The inventive chassis (1) has a so-called box construction.  It comprises a lower and an upper carrier plate (2, 3), which are reinforced and joined by stiffening elements (12) located between them.  This construction leads to an enormous load-carrying capacity and an extremely high rigidity with respect to twisting in the case of an only limited height of chassis (1).  Unlike in the case of conventional chassis constructions with an overall height of 30 to 40 cm, minimum heights of approximately 10 cm are possible here.  By covering the outer fronts of the chassis with vertical coverplates, an additional stiffening is obtained.        These measures permit a shaping, which permits a very low mounting of the chassis, even when using large wheels.  As a result of the inventive chassis, it is possible to use telescopic axle suspensions, such as are e.g. described in Swiss patent application 531/87. This makes it possible to adjust the vehicle position, even when driving and without additional means.  A construction with a relatively low weight is also obtained.

Title: Overburn process for recovery of heavy bitumens
Inventor: STEPHENS DAVID J
IPC: E21B43/247
Filed: 1988-10-11
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE     A method for the production of bitumen from a subterranean reservoir having a zone of increased effective permeability therein.  In particular, a first well is in fluid communication with the zone of increased effective permeability at a first level in the reservoir.  Fluid communication is established between a second well and the zone of increased effective permeability at a second level above the first level in the reservoir.  In-situ combustion is initiated in the reservoir proximate the second well.  Combustion sustaining fluid is injected through the second well into the zone of increased effective permeability so that bitumens in the reservoir are mobilized by the in-situ combustion and flop downward through the reservoir towards the first well, through which they are recovered.  By using this method, a stable in-situ combustion process is established which avoids fingering and channelling and accompanying early oxygen breakthrough, consequently improving the efficiency of bitumen production from the reservoir.

Abstract: Abstract:   The invention relates to a single-lever mixing valve assembly havingthermostatic control means. The valve assembly is provided with control discs 20, 23, 25, 24. One control disc forms a stationary valve seat 20 and has inlet ports 21, 22 for cold and hot water, the ports 21, 22 being connected to the cold and hot water inlets 18, 19 of the valve at one side and directed towards a movable disc 23 at the other side. The movable disc 23 is displaceable on the valve seat 20 and contains passages 28, 29 communicating with the inlet ports 21, 22 of the valve seat 20 for shutting off and flow control. This movable disc 23 acts as a lower guide disc for a temperature control disc 25, which is displaceable between said movable disc 23 and an upper guide disc 24. A thermoelement 39 is positioned between the lower and upper guide discs 20 and 24 respectively, and accommodated in a cavity 32 in the temperature control disc 25. Recesses 35 in the control disc 25 form mixing chambers which are in direct contact with the cavity 32 and thus with the thermoelement 39. With this invention the preset mixed water temperature can be quickly and precisely controlled and maintained. The invention is an improvement of our patent case Folio 13116.

Title: Process for treating the surface of polyimides to improve properties to receive metal layer
Inventor: ANSCHEL MORRIS
IPC: C08J7/14

Granted: 1994-06-07
Abstract: ABSTRACT OF THE DISCLOSURE      A process is provided for improving the surface properties  of  polyimide  articles  which  contain significant amounts of transimide.  The surface of the polyimide containing the transimide is first treated with a base to convert the surface layer of both the polyimides and the transimides to the polyamic salt. Thereafter the surface layer of the converted polyamic salt is treated with an acid to convert the layer to a polyamic acid.  This is followed by a cure preferably in infrared radiation at a sufficiently rapid rate to prevent the formation of any significant amounts of transimide and provide only polyimide.  Following this treatment metallization is applied to the  improved surface layer.
