Title: Opening lock for a sunshade
Inventor: LEE CHORNG-CHENG
IPC: A45B25/08
Filed: 1998-12-09
Abstract: An improved opening lock for use in a sunshade or a parasol which is housed in a cavity defined on the shaft of the sunshade. The present opening lock has a stop block having a smoothly curved guide bottom at the front end and a bias spring disposed behind the stop block and a fixing element for mounting the spring, and a cover plate which confines the stop block and the spring and the fixing element inside the cavity so that the runner of the sunshade slidably disposed on the shaft is able to move against the lock, pushing the lock into the cavity when the runner traveling upward to make the sunshade open, and the stop block is able to pop out when the runner passing the same and to support the runner in place, keeping the sunshade opened. To close the sunshade, the stop lock must be pushed into the cavity to permit the runner slide downward.

Patent CA-2259612-A1 (CA)
Title: Fissile shock tube and method of making the same
Inventor: GLADDEN ERNEST L
IPC: C06C5/04
Filed: 1997-07-07
Abstract: An initiation signal transmission line tube (10a, 10b, 10c, etc.), which is effective to transmit an initiation signal therethrough, contains one or more rupture lines (20a, 20b and 20c, etc.) in the tube wall. Rupture lines (20a, 20b and 20c, etc.), which may be weld seams or grooves or both, are ruptured by the initiation signal passing therethrough. The spent tube carcass is split or fragmented and therefore less troublesome as litter on a work site than an intact shock tube carcass. If the tube is extruded, a rupture line may be formed by contacting the parison (118) from which the tube is made with scoring means, e.g., a pin or blade (124a, 124b). Optionally, the scoring means may be moved radially during the extrusion process, to form serpentine, e.g., helical, rupture lines. Preferably, the rupture lines intersect periodically and, upon firing, the tube is fragmented into shards.  Alternatively, the tube (50d) may be extruded in segments (62) that adhere to each other at interfaces (64) which provide rupture lines for the tube.

Patent CA-2264470-A1 (CA)
Title: Timing recovery system
Inventor: AMAN AHMAD K
IPC: H04L7/033
Filed: 1999-03-05
Abstract: A digital timing recovery system advantageously employs both demodulated I-phase and Q-phase components to more accurately locate the synchronization signal of an incoming VSB signal. The Q-phase component is advantageously employed to detect the phase error. The use of the Q-phase component provides a more accurate measure of the phase error and results in a larger (wider) acquisition range for timing frequency offset. More specifically, the timing recovery system of this invention performs symbol clock recovery based on the VSB signal segment synchronization (sync) signal and generates a pulse density modulated (PDM) phase difference signal that controls a voltage controlled crystal oscillator (VCXO) in the phase-locked loop. This is realized, in one embodiment of the invention, by correlating received sync segment data with the known sync signal pattern and searching for "peaks" in the correlation values that are periodic at the known sync segment data rate. Once the sync pattern is found, the correlation values for adjacent samples are advantageously employed to generate the necessary feedback control signal value for the VCXO. Technical advantages of applicants' unique invention are that the need for an analog synchronous detector is eliminated, a more accurate measure than that obtained by prior known systems is obtained and a wider acquisition range is obtained for timing frequency offset.

Title: Process for the production of radioiodinated neuroreceptor agents
Inventor: HILTUNEN JUKKA
IPC: C07D453/02
Filed: 1998-06-15
Abstract: The present invention is related to a process for producing radioiodinated neuroreceptor agents with improved yields. In said process the trialkyltin group of the precursor of the neuroreceptor agent is replaced by radioiodine in the presence of an oxidation agent, preferably Chloramine T in a pH  adjusted by a buffering system comprising inorganic or organic acids and their salts. The end-products are subsequently separated from the by-products using chromatographic separation methods such as high performance liquid chromatography (HPLC), wherein the mobile solvent phase comprises a mixture of ethanol and water having a pH of 1-6. The improved yields are obtainable by preventing the formation of volatile radioactive by-products and by using a non-toxic solvent system in the chromatographic separation process, which simplifies the down stream processing of the end product.
Patent CA-2294349-A1 (CA)

IPC: A61P13/08
Filed: 1998-06-17
Abstract: This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha la adrenergic receptor antagonists.  One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved.
