Patent CA-2143296-A1 (CA)
Title: New bacillus thuringiensis strains and their insecticidal proteins
Inventor: LAMBERT BART
IPC: A01N63/50
Filed: 1993-07-12
Abstract: Four novel Bacillus thuringiensis strains, which are deposited at the BCCM-LMG under accession nos. LMG P-12592, LMG P-12593, LMG P-12594, and LMG P-13493, produce new crystal proteins during sporulation that are toxic to Lepidoptera, more particularly against Noctuidae such as Spodoptera spp. and Agrotis ipsilon, against Pyralidae such as Ostrinia nubilalis, and against Yponomeutidae such as Plutella xylostella, and that are encoded by a novel gene. The crystal proteins contain protoxins, which can yield a toxin as trypsin-digestion product. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that encodes its respective toxin, is resistant to Lepidoptera. Each strain, itself, or its crystals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Lepidoptera.
Patent CA-2143806-A1 (CA)
Inventor: TAL ZEEV
IPC: A47K5/00
Filed: 1995-03-02
Abstract: A device to squeeze out a desired quantity of the pasty contents of a flexible or collapsible tube. The device is an integral structure having two elongated members connected by a frame at both pairs of corresponding ends.    At least one of the elongated members has a resilient tongue integrally attached to its free elongated side and not connected to the frame. The resilient tongue is a U-shaped leaf spring. One side of the leaf spring is integrally attached to the free elongated side of the elongated member. The other side of the leaf spring is free. The free elongated side of the elongated member and the resilient tongue, or two resilient tongues in the case where the two elongated members have resilient tongues attached to them, define an opening that narrows gradually from a relatively wide entrance to a narrow slot. The width of the entrance is correlated to the thickness of the rear end of the tube through which the seal end of the tube is inserted. The width of the slot is correlated to the double wall thickness of the tube.      Pressure is exerted on the walls of the tube to flatten the tube while sliding on it. A constant force is applied on the pressed together, flattened walls of the tube holding the walls of the part of the tube engaged by the slot firmly closed. Separation between the front full part and rear emptied part of the tube prevents escape of the contents of the tube backwards. It also prevents any unwanted sliding of the device along the tube. The resilient tongue or tongues press the walls of the tube together. In this way, desired quantities of the contents of the tube is squeezed out of the tube in the conventional manner by pressing the walls of the front full part of the tube together or by pushing the device towards the front full part of the tube. The device facilitates the use of these widely available flexible tubes. The device also prevents backflow of the retained contents of the tube.

Patent CA-2148766-A1 (CA)
Inventor: WREZEL PAUL WILLIAM
IPC: A23C19/032
Filed: 1995-05-05
Abstract: The present invention is directed to a method for making a higher moisture, reduced fat natural cheese product from partially or wholly fat reduced milk.  The cheese product of the present invention has from about 45% to about 58% moisture and from about 1.3% to about 15% butterfat.  In the method of the invention for making a reduced fat natural cheddar-type cheese, milk is standardized in fat content to produce a milk substrate having from about 0.05% to about 2% milkfat.  A culture and a small, but effective, amount of yeast cell particles are added to the standardized milk. Thereafter, the milk is fermented and set with a milk coagulating enzyme.  The coagulum is cut to provide curd particles and whey and the curd particles are cooked in the whey.  The whey is drained from the curd and the curd is rinsed, salted and filled into containers.  The curd is pressed and vacuumed to remove additional whey, the container is sealed and the curd is cooled in the container.  Thereafter, the curd blocks are cured to provide a natural cheddar type cheese product having a reduced fat level which is from about 40% to about 98% less than the fat level of conventional cheese products. In the manufacture of pasta filata natural cheeses, such as mozzarella, the curd is stretched under hot water prior to curing.

Patent CA-2154743-A1 (CA)
Title: Method and apparatus for electrosurgically treating tissue
Inventor: HASSLER WILLIAM L
IPC: A61B18/12
Filed: 1995-07-26
Abstract: Tissue impedance of tissue impedance in combination with tissue temperature is used to control electrosurgical tissue treatment. Tissue impedance alone provides better control of electrosurgical treatment by determining an initial maximum tissue impedance, a minimum tissue impedance selecting a point between the maximum and minimum impedances, preferably the average, as an impedance threshold, and turning off rf power to the electrosurgical instrument when the impedance reaches the threshold as it rises from the minimum. Control may also be by the combination of tissue impedance and temperature. Temperature is controlled to maintain a selected preferred temperature and a maximum temperature is also selected so that if the tissue reaches the maximum temperature, power is turned off. Impedance control is combined with temperature control so that the temperature of the instrument is maintained at a selected preferred temperature unless a maximum temperature is exceeded, which normally will not happen. The impedance is also monitored with maximum and minimum values being determined as well as a threshold impedance between the max and the min. When the threshold, preferably the average impedance, is reached, power is removed from the instrument.

IPC: G01N21/64
Filed: 1996-04-04
Abstract: In the optical detection device (1), the excitation light guide (11) and the emission light guide (12) form a structural unit having the end face (14) facing the fluorescence changer (4). The end face (14) physically corresponds substantially to one of the boundary surfaces of the two light guides (11, 12). As a result, the detection device (1) can be separated in a simple manner into an optical part and a mechanical part which are in optical contact only by way of the end face (14). All of the elements in the optical light path are connected in a mechani-cally stable manner by means of the index-matching medium 20, as a result of which the light between the light source (10) and the photoelectric sensor (13) propagates only in media having a comparable refractive index. The light source (10) is preferably a light--emitting diode.   A plurality of those detection devices can be combined to form a compact detection apparatus with which the substance (3) can be examined with regard to several constituents in one measuring operation.
