Patent CA-2321617-A1 (CA)
Title: Cold connection
Inventor: WALDECK KLAUS-DIETER
IPC: B62D27/06
Filed: 2000-10-02
Abstract: Linear cold connection (1) with connecting places (12, 20, 23) contains a first and second structural component (2, 3) to join a first and second construction elements of a frame for road or rail bound vehicles. First construction elements are attached to the first structural component (2) and second construction elements are attached to the second structural component (3). The first and second structural components (2, 3) are joined together via a pair of first and second joint faces (5a, 5b). The joint faces (5a, 5b) form a length of arc of a circular cylinder with common circular-cylinder axis (16). The first structural element is joined to the second structural element (2, 3) via a bolt-type connection penetrating openings (17, 18) in the first and second joint faces (5a, 5b). The diameters of the openings (17, 18) transverse to the circular-cylinder axis (16) are larger than the diameters of the bolts (10) where they penetrate the openings (17, 18) with the result that, when the bolt-type connection is loose, both structural components (2, 3) can be displaced with respect to each other by relative movement of the first and second joint faces (5a, 5b) transverse to the circular-cylinder axis (16) and with that accommodate tolerances.

Patent CA-2326571-A1 (CA)
Title: Controlling the set-up of calls between subscriber stations
Inventor: SPINNER ARNO
IPC: H04N1/00
Filed: 1999-03-30
Abstract: The invention relates to a control apparatus (AGNT), a telecommunication system (SYS), a control method and a subscriber sttion (SS1, TE, MT; SS2, TE, MT; SS3, TE, MT) wherein a call set-up request issued by a first subscriber station (SS1) is blocked from a transfer to a telecommunication network (NET) as long as the second subscriber station (SS2) to which a call should be set-up is in a busy state. The control apparatus (AGNT) only transfers the call set-up request to the exchange means (MSC/VLR, GMSC, HLR) of the telecommunication network (NET) when the called second subscriber station (SS2) changes from a busy state into an idle state. Thus, the network resources are not occupied by call set-up requests which would be rejected due to the second subscriber station (SS2) being in a busy state. The invention is particularly advantageous when the calling subscriber station (SS1) uses a re-dial function to repeat a call set-up request. After several retries further retries will be blocked and the call will only be set-up when the second subscriber station becomes free. A particular advantageous application of the invention is to combine the blocking of call set-up requests by the control apparatus (AGNT) with a CCBS service implemented in the network (NET).

Patent CA-2332799-A1 (CA)
Title: Frequency estimation of electro-islet-graphy
Inventor: CHARASH DAN
IPC: A61B5/04
Filed: 1999-05-28
Abstract: The fundamental frequency of EIG events is determined directly, without first detecting the events themselves.    Use is made of an analysis window containing more than one event (3-5). Techniques (1-8) are utilized which are somewhat similar to those utilized to detect, and estimate pitch in speech processing. The invention is based on two important biological discoveries. The first is that the EIG is generated by a functional pace maker.  The second is that the EIG signal is quasi-periodic most of the time. The use of pitch detection algorithms is based on the essentially quasi-periodic nature of the EIG  signal. Quasi-periodic means that the intervals between successive events are not exactly identical, but may vary slightly, that the amplitude and shape of successive events may also exhibit some variance.

Patent CA-2342805-A1 (CA)
Inventor: YOSHIOKA YUUICHI
IPC: C12N11/02
Filed: 1999-06-22
Abstract: A method for recovering soil polluted with organic compounds (pesticides, etc.) by degrading the organic compounds with a bacterium and for preventing underground water from pollution. A method for accumulating a bacterium capable of degrading specific organic compounds onto a porous material provided with a number of pores onto which the organic compounds can be adsorbed and in which the bacterium can easily grow. In this method, the porous material is inoculated with the isolated degrading bacterium alone to form a accumulation layer made of the thus inoculated porous material. Next, an inorganic salt medium containing the above-mentioned organic compounds exclusively as a carbon and nitrogen sources is refluxed through the accumulation layer to thereby accumulate the bacterium onto the porous material at an elevated rate. The carrier holding the degrading bacterium thus formed is directly embedded in the polluted soil.
Patent CA-2343059-A1 (CA)
Inventor: AGASHE PARAG A
IPC: G01S1/00
Filed: 1999-09-02
Abstract: Method and apparatus providing enhanced sensitivity for GPS receivers (400, 500, 600, 700) by allowing coherent integration of a correlation over several code periods of a GPS signal in one embodiment, and by performing a time to frequency domain conversion to the output from a correlation processor (507) in a second embodiment. In the case in which coherent integration is performed over several code periods, advantage is taken of the fact that CDMA cellular telephone base stations transmit information that allows the receiver to determine GPS time before beginning a GPS signal acquisition process. The integration can be expanded to include code periods from more than one bit period, if the GPS receiver (400, 500, 600, 700) takes advantage of the fact that known bit patterns are transmitted at particular times within the transmission from a GPS satellite. If no base station is within range, then the output from a correlator (507) that integrates a correlation over one code period is used to generate values that are input to a discrete time domain to frequency domain transform processor (511). The output from the transform processor (511) will indicate the presence of a signal from a particular satellite and the offset between locally generated signal and the received GPS signal.

Inventor: BROAD ROSS
IPC: E21B43/1185
Filed: 2001-09-28
Abstract: A downhole tool hydraulic firing head includes an automatic drain that is opened when the piston is driven to fire. The automatic drain includes a vent opening from the bore and a sleeve disposed within the bore to move axially with the piston. The sleeve is moveable from a position covering the vent opening to a position clear of the vent opening. A locking collet is disposed between the sleeve and the housing, which locks the sleeve into the position, clear of the vent opening, when the sleeve is moved into that position. This locks the sleeve against returning to the position covering the vent opening when it is urged to move in that direction such as, for example, by venturi forces of the evacuating fluid or by pressure generated from the explosive charges. The firing head is useful to detonate downhole explosive charges, such as those in a perforating gun.

Title: Fast dispersing dosage forms free of gelatin
Inventor: GREEN RICHARD
IPC: A61K9/20
Filed: 2000-01-27
Abstract: The present invention relates to fast dispersing solid dosage forms that preferably dissolve in the oral cavity within sixty (60), more preferably within thirty (30), most preferably within ten (10) seconds. A  novel feature of the solid dosage forms according to the invention reside in the fact that the composition is essentially free or absolutely free of mammalian gelatin. It has been discovered that the use of certain modified starches at concentrations from 20 to 90 % by weight of the solid dosage form prepares dosage forms that are mechanically and chemically stable and are able to deliver higher concentrations of an active ingredient than the heretofore utilized gelatin based fast dispersing solid dosage forms. Further, the solid dosage forms according to the invention are obtainable by removing a solvent, such as water, from a mixture comprising an active ingredient, a modified starch and a matrix forming agent via freeze drying.
