Title: Cassette blind with brake coupling
Inventor: BENTHIN SIEGFRIED
IPC: E06B9/68
Filed: 1995-09-20
Abstract: The present invention pertains to a cassette blind with a weighting profile at the lower end of a set of blinds and with a blind drive, in which coupling elements with a winding shaft mounted in the cassette profile, complementary coupling elements with a drive member and complementary coupling elements at a pin which can be stationarily fastened are arranged, wherein coupling elements of the drive member and of the winding shaft mutually engage each other during a rotary movement of the drive member in the winding-up direction of the blinds, and coupling elements of the winding shaft and of the pin mutually engage each other in the opposite direction. The coupling elements at the winding shaft are arranged rotatably over a predetermined angle against spring action in the winding-up direction of the blinds in order to achieve a torsionally elastic tensioning of the weighting profile at the cassette profile at the end of the winding-up movement of the blinds.

Title: Intelligent shopping cart
Inventor: SCHKOLNICK MARIO
IPC: G06Q20/20
Filed: 1996-02-06
Abstract: The present apparatus is a mobile shopping cart that can automatically keep track of objects selected and carried in the cart and provide a customer using the cart information like the total price of the items carried. The cart has a radio frequency cart base station with a cart antenna connected to a radio frequency cart transceiver. Various novel embodiments of the invention produce a radio frequency field within the shopping cart that is used to communicate with radio frequency tags on objects carried in the cart. The tags contain information about the respective carried object to which the tags are attached. A program function executed by the cart circuit and/or computer controls the cart transceiver to interrogate radio frequency tags within the radio frequency field, i.e. inside the cart to gain information about the carried objects. Tags on objects external to the cart are not interrogated.

Title: Anhydrous magnesium chloride
Inventor: SHEEHAN GREGORY JOHN
IPC: C01F5/34
Filed: 1994-10-28
Abstract: Anhydrous magnesium chloride is prepared by a process in which hydrated magnesium chloride (10) is mixed in a vessel (11) with ethylene glycol (12). The mixture (13) is dehydrated in distillation columns (14, 15 and 16) with the dehydrated ethylene glycol magnesium chloride solution (20) pumped into a crystalliser (21) simultaneously with the separate addition of anhydrous ammonia gas (22) to the crystalliser (21). Prior to the introduction of reactants (20 and 22), the crystalliser (21) contains ethylene glycol saturated with ammonia. A crystalliser slurry of magnesium chloride hexammoniate (23) is continuously pumped from the crystalliser (21) into a pressure filter (24) where the crystals are washed with methanol saturated with ammonia (26). The washed crystals (27) are transferred to a fluidised bed calciner (23) where methanol is evaporated from the crystals at 120°C and therefter the crystals are calcined to anhydrous magnesium chloride at 450°C.
Patent CA-2176117-A1 (CA)
Title: Generation of high titers of recombinant aav vectors
Inventor: FLOTTE TERENCE R
IPC: A61K35/76
Filed: 1994-11-03
Abstract: AAV vectors may have utility for gene therapy but heretofore a significant obstacle has been the in-ability to generate sufficient quantities of such recom-binant vectors in amounts that would be clinically useful for human gene therapy application.  Stable, helper-free AAV packaging cell lines have been elusive, mainly due to the activities of  Rep protein, which down-regulates its own expression and reverses cellular immortaliza-tion.  This invention provides packaging systems and processes for packaging AAV vectors that effectively circumvent  these problems by replacing the AAV  p5 promoter with a heterologous promoter (as depicted in the figure) and that allow for substantially increased packaging efficiency.

Abstract: A bag-in-the-box container (64) comprises a box (10) folded from flexible sheet material and having side walls (12, 14, 16), a bottom closure and a top closure. An integral pouring spout forma-tion (66) is formed between one of the side walls (16) and the top closure. The pouring spout forma-tion (66) comprises a lower pro-jecting wall (30) which folds along a lower fold line (32) with respect to the side wall (16) and an up-per wall arrangement including a rear portion (72B, 78) which forms part of the top closure and a front projecting wing portion (72A, 76) which is delineated from the rear portion (72B, 78) by means of at least one upper fold line (73, 73A). The upper wall (36) is pre-formed to bow upwardly above the plane of the top closure and the lower projecting wall (30) so as to de-fine a spout passage in conjunction with the lower projecting wall (30) when the pouring spout formation (66) is in the raised pouring position and to collapse towards the lower projecting wall (30) when the pouring spout (66) is folded downwardly into a lowered position against the side wall (16). A fluid-tight bag (60) is arranged to fit into the box (10), the bag (60) having an inner spout which is located within the spout passage. The tip of the inner spout is arranged to nest within the tip of the pouring spout formation (66), so that both tips can simultaneously be snipped off in a single cutting operation to obtain access to the fluid within the bag (60). The invention extends to a method of forming a bag-in-the-box container.

Abstract: Signal reconstruction methods reconstruct a missing portion of a signal from a first known portion of the signal preceding the missing portion, and a second known portion of the signal succeeding the missing portion. The first known portion of the signal is represented using a first autoregressive model and the second known portion of the signal is represented using a second autoregressive model. These methods construct a signal estimate from the first and second autoregressive models, thereby permitting the reconstruction of any signal having a missing portion, irrespective of whether or not the length of the missing portion is greater than the short-term stationarity duration of the signal.

Inventor: GRANDE RENE SHOAN
IPC: E21B47/04
Filed: 1997-03-27
Abstract: A well collar counting methodology is provided comprising first obtaining acoustic pulse data from a well and then digitizing and storing the amplitude-versus-time signal for subsequent processing. The raw signal is processed by applying a Wavelet Transform thereto for producing multiple resolutions of the signal, preferably four, at least one of which has a transformed signal resolution sufficient to distinguish reflections emanating from collars, and one of the coarser resolutions having a transformed signal resolution sufficient to distinguish reflections emanating from the fluid surface as kicks. The fluid surface kick and repeat kicks are determined by performing multi-resolutional analysis of each maximum, at the coarser resolution, as synchronized against the successively finer resolutions and compared as being significant with respect to adjacent maximums. Tubing collars are then counted at a finer resolution, as being reflection maximums counted in the interval between the wellhead and the kick, irrespective of tubing joint length or collar frequency. Direct collar counting, interpolation and extrapolation of collars is performed.
