Abstract: In order to detect a paging channel assigned to a pager in a shorter time in a frequency divided pager network system, a plurality of paging channels given priorities in channel searching are separately assigned to the paging areas in a manner wherein reuse in adjacent paging areas is avoided.    A frequency subset number and frequency subset indicators related thereto, are stored in a memory in a pager.          Subsequently, paging channels available in the system are allocated to the frequency subset indicators.  Further, a relationship between the frequency subset indicators and the corresponding paging channels is arranged in the form of a table and then stored in the pager.  Then, the paging channels are assigned to the paging areas according to the relationship.  The above mentioned paging channels given priorities in channel detection are monitored so as to detect which priority channel is transmitted to the pager.  In the event that the pager detects one of the priority paging channels, the pager is tuned to other paging channels according to the relationship.

Patent CA-2092733-A1 (CA)
Title: Ltd4 receptor and photoaffinity probe
Inventor: ZAMBONI ROBERT
IPC: C07K5/072
Filed: 1993-03-26
Abstract: The leukotriene (LT)D4 receptor has been defined by radioligand binding studies as a member of the family of G-protein coupled receptors. In order to characterize this receptor a radioiodinated, photoactivable azido derivative of LTD4 ([125l]Azido-LTD4) has been synthesized for use as a photoaffinity probe. The characteristics of [125l]Azido-LTD4 specific binding to guinea-pig lung membranes were directly comparable with those of [s H]LTD4 specific binding to this tissue, in agreement with [125l]Azido-LTD4 binding to a G-protein coupled LTD4 receptor. [125l]Azido-LTD4 specific binding was saturable and of high affinity, enhanced by divalent cations and inhibited by sodium ions, but not potassium ions.  [125l]Azido-LTD4 specific binding was also strongly inhibited by the non-hydrolysable GTP analogue GTP.gamma.S with ATP.gamma.S being 100-fold less potent, suggesting this inhibition was due to selective interaction with a G-protein. The peptidyl leukotrienes competed for [125l]Azido-LTD4 specific binding with the following rank order of potency: LTD4 > LTE4 >> LTC4, while the non-peptidyl LTB4 was virtually inactive. Two structurally different LTD4-receptor antagonists, MK-571 and ICI 204,219, also competed for [1251]Azido-LTD4 specific binding to guinea-pig lung membranes, with nanomolar potency, whereas the leukotriene biosynthesis inhibitor MK-886 was 10000-fold less active. Photoactivation of [125l]Azido-LTD4 under equilibrium binding conditions revealed the selective radiolabeling of a 45 kDa protein in guinea-pig lung membranes, as visualized by SDS-PAGE and autoradiography. The photolabeling of this protein was inhibited in a concentration-dependent manner by all competing ligands, with the same rank order of potency and IC50 values as determined in the [125l]Azido-LTD4 binding assays.  In addition, the radiolabeling of this 45 kDa protein was saturable, modulated by cations, and inhibited by nucleotide analogues in an analogous way to [125l]Azido-LTD4 specific binding to guinea-pig lung membranes. It is therefore proposed that this novel 45 kDa protein represents the LTD4 receptor.

Patent CA-2110647-A1 (CA)
Inventor: BERTONE DANIELE
IPC: H01L21/205
Filed: 1993-12-03
Abstract: The vapour generator for chemical vapour deposition plants allows the extraction of metalorganic vapours from liquid or solid sources.  It mainly consists of a container into which a gas flows in, and as it passes near the reagent, it is saturated with the vapours produced and transports them to the reaction chamber.  Only the generator is brought to a temperature which is higher than room temperature so as to obtain a vapour which is saturated with a high quantity of reagent.  To avoid vapour condensation in the pipe system transporting it from the generator to the reaction chamber, it is diluted with a carrier gas directly in the body of the heated generator, reducing in this way the condensation temperature of vapour which becomes unsaturated.  For this purpose, the generator contains a dilution bypass-line in the upper base into which the carrier gas is made to flow. The pipe system going from the generator to the reaction chamber can be held at room temperature without any condensation risks.
