Abstract: This invention relates to a low pH nutritional beverage that utilizes pectin-free fruit juice as a major component and a source of calcium selected from natural milk mineral, calcium lactate gluconate and mixtures thereof. The beverage preferably also contains water soluble vitamins, flavors and carbohydrates. The use of a pectin-free and clarified pear juice in a preferred embodiment of the beverage provides a fat-free beverage with a substantially clear appearance and a light, refreshing mouthfeel. The beverage is preferably produced using a "cold water process" that results in excellent physical stability of the beverage over shelf life and the reduction of browning.

Title: Ultrasonic probe and method for improved fragmentation
Inventor: CIMINO WILLIAM W
IPC: A61B17/22
Filed: 1999-10-06
Abstract: In general the ultrasonic probe for improved fragmentation is comprised of a longitudinal shank (11) having a proximal end (12), a distal end (13), and a shaft (14). The shaft joins the proximal end, and the distal end. The proximal end of the longitudinal shank has a connector (15) for connecting the longitudinal shank to a source of ultrasonic vibrational energy. The distal end of the longitudinal shank may have a blunt or bullet nosed tip (16). The shaft has one or more grooves (17) near the tip which circumscribe the shaft of the longitudinal shank. The walls of the grooves provide surface area on the distal end of the probe in planes generally prependicular ot the axis of the probe. The additional surface area increases the tissue fragmenting surface area of the distal end of the probe without increasing the diameter of the distal end of the probe.

Patent CA-2353032-A1 (CA)
Title: Subtraction in a viterbi decoder
Inventor: BRICK CORMAC
IPC: H03M13/41
Filed: 2001-07-12
Abstract: A Viterbi decoder for decoding a convolutional code. For each possible state, an accumulated error AE is maintained at 66. As each codeword Rx-GP is received, the errors between it and the code groups of all the transitions are determined at 65. For each possible new state, logic 68 determines the errors of the two transitions leading from old states to that new state, adds them to the accumulated errors of those two old states, and determines the smaller of the two sums. Path logic 67 records the corresponding transition, updating a record of the path leading to the new state. Tracing back along a path a predetermined and sufficiently large number of transitions, the input bit or bits corresponding to the transition so reached are taken as the next bit or bits in the stream of decoded bits.      To renormalize the accumulated errors, the smallest accumulated error is determined by a minimum accumulated error determining unit 57 and subtracted from the errors from unit 65 by subtractors 80 before the additions and comparisons in logic 68. The unit 57 comprises a tree of comparators fed with the accumulated errors.

Title: Operating device for discharge lamps with switch relief for the preheating of electrode filaments
Inventor: HECKMANN MARKUS
IPC: H05B41/295
Filed: 2001-07-26
Abstract: In order to heat filaments of discharge lamps, use is often made of a filament transformer (L11, L12, L13) in the associated operating devices. Particularly in the case of preheating the filaments, there is then a lack of a sufficiently high inductive component in the load current in order to ensure turn-on relief of the half-bridge switches (S1, S2) for operating devices with a half-bridge circuit. By inserting an air gap into the filament transformer (L11, L12, L13) the switch relief can be effected even in the case of preheating or of a low dimming setting.

Patent CA-2357314-A1 (CA)
Title: Hemming machine
Inventor: BAULIER DOMINIQUE
IPC: B21D39/02
Filed: 2001-09-14
Abstract: A hemming machine is disclosed having a base, a nest adapted to support a part to be hemmed, a nest carrier which supports the nest and in which both the nest and nest carrier are vertically movably mounted to the base. At least one hemming die is laterally slidably mounted to the base and movable between an extended position in which the die overlies a portion of the nest, and a retracted position in which the die is spaced laterally outwardly from the nest. A lock unit selectively locks the nest carrier against vertical movement relative to the base in at least one, and preferably two positions, so that, with the nest carrier locked against movement relative to the base, inflation of a hydraulic bladder sandwiched between the nest and nest carrier displaces the nest vertically upwardly from the carrier so that the part carried by the nest is compressed against the hemming dies and performs the hemming operation. Preferably, a single drive shaft not only displaces the nest and nest carrier, but also powers the hydraulic circuit to inflate the bladder and thus upwardly displace the nest relative to the nest carrier with an amplified force required to achieve the final flattening of the hem.

Abstract: L'invention concerne des vecteurs d'expression rétroviraux et notamment des pseudotypes de vecteurs rétroviraux destinés à la thérapie génique du cancer. Le ciblage direct "in vivo" des tumeurs avec des vecteurs viraux "suicidaires" est limité par l'inefficacité du transfert de gènes et par le transfert non discriminé d'un gène conditionnellement toxique vers des tissus environnants non malins. L'utilisation de rétrovirus dont on a obtenu le pseudotype avec une protéine G du virus de la stomatite vésiculaire (VSVG) peut apporter une solution au problème. Ces particules rétrovirales se distinguent, dans le cas des rétrovirus murins standard, par leur tropisme très large et par leur capacité d'être concentrés par ultracentrifugation sans perdre leur activité. On peut utiliser un rétrovecteur dont on a obtenu le pseudotype avec VSVG pour un apport in vivo efficace de la thimidine kinase (TK) du virus herpès simplex. Selon cette invention, on a construit un vecteur rétroviral cistronique qui exprime la TK et la protéine verte fluorescente (pTKiGFP).
