Title: Technique for time-division duplex cordless telecommunication
Inventor: ALBROW RICHARD
IPC: H04W72/08
Filed: 1990-01-26
Granted: 1999-08-31
Abstract: A communication procedure suitable for a cordless telephone system involves time division duplex radio communication between a handset (11) and a base station (3) using alternating bursts of transmission over a single radio channel. Once a radio link has been set up, initial transmissions carry a synchronisation logical channel S and a signalling logical channel D multiplexed together, but the link may switch to bursts carrying a communications logical channel B for the speech data and the signalling logical channel D. Burst synchronisation is achieved by the asynchronous detection of words in a synchronisation channel S. These words have bit patterns reducing the probability of incorrect asynchronous detection of them. If one part ceases to receive handset signals from the other, it transmits a special signal, informing the other part. This enables both parts to detect the failure of a link at substantially the same time, so that their actions to re-establish the link are synchronised.
Patent CA-2027603-C (CA)
Title: Cooling liquids
Inventor: BRIDDEN TERENCE EDWARD
IPC: C09K5/06
Filed: 1990-10-15
Granted: 2001-07-31
Abstract: Liquid is cooled in a columnar vessel 2 having an inlet 4 and an outlet 6 for the liquid. The cooling is effected by introducing liquid cryogen into the vessel 2 through a pipe 14. The liquid cryogen vaporises and crates turbulence in the liquid in the vessel 2. Perforated plates 12 dampen the turbulence and disengage the vaporised cryogen from the liquid being cooled. Pressurised gas is introduced from an inlet 16 into the liquid beneath the liquid cryogen. This pressurised gas crates turbulence in the region where the cryogen enters the liquid and thus is able to prevent local freezing of the liquid in the mouth of the pipe 14. The liquid is typically water and the liquid cryogen typically liquid nitrogen.

Title: Dual mode document registration system
Inventor: RYON RANDALL C
IPC: G03B27/62
Filed: 1991-06-17
Granted: 1995-08-01
Abstract: A system for efficiently feeding normal sized and oversized documents into different imaging positions overlying an imaging platen. All documents are initially fed onto the platen from an infeeding position desirablefor normal documents substantially downstream from the upstream end of the platen. A normal document is only fed unidirectionally downstream into an imaging position. A sensed oversized document is initially fed downstream, but then, after its trail edge has cleared the infeeding position, it is reverse fedtowards the upstream end of the platen into a special imaging position partiallyoverlying the normally unused upstream portion of the platen. A baffle normally directly overlies that area of the platen. During the initial reverse movement of an oversized document his baffle is pivoted upwardly at its downstream edge, at the infeeding position, to provide a document guide surface under the baffle. The baffle is then lowered onto that portion of the oversized document now extending thereunder before its imaging to provide an imaging background surface, and may be raised again for downstream ejection of the oversized document. For normal documents the baffle may remain flat on the platen.

Title: Adaptive buffer/quantizer control for transform video coders
Inventor: HANG HSUEH-MING
IPC: H04N7/32
Filed: 1991-08-28
Granted: 1994-02-22
Abstract: Adaptive Buffer/Quantizer Control for Transform Video Coders Abstract A buffer/quantizer controller in a video coder utilizes the average quantization step size employed for the previous frame, the average number of bits produced per pel by the video coder for the image contained in the previous frame and the current frame buffer fullness level to obtain an indication of image complexity. A target current frame quantization step size be employed by the video coder in encoding a current frame is based on the indication of image complexity. Optionally, the target frame quantization step size is adjusted by amapping procedure, at predetermined intervals within each frame period, to account for the current buffer fullness. The map employed by the mapping procedure is adjusted in accordance with the target frame quantization step size [FIG. 3].

Granted: 1996-06-18
Abstract: Polypeptides are synthesized over a several hour period in a cell-free system containing an exogenous prokaryotic RNA polymerase, a DNA molecule which encodes a polypeptide of interest, and additional substrates.  In the cell-free polypeptide synthesis method,  a mixture which includes a eukaryotic cell extract capable of supporting in vitro translation, ATP, GTP, CTP, UTP, and amino  acids  is  added  to  a  vessel  containing  an ultrafiltration membrane barrier.   Reaction substrates including  ATP,  GTP,  CTP,  UTP  and  amino  acids  are continuously delivered to the vessel at a rate that maintains their initial concentration in the vessel while the products of the process, including AMP, GDP, CDP, UDP,  pyrophosphate,   inorganic  phosphate,   and  the polypeptide product are continuously removed from the vessel through the ultrafiltration barrier.  Included in the reaction mixture is an exogenous prokaryotic RNA polymerase  and  a  DNA  molecule  which  encodes  the polypeptide of interest and contains a promoter site specific to the exogenous RNA polymerase.

Granted: 1995-09-19
Abstract: An elevated wall reservoir system that has a floating cover assembly that lies directly on the top surface of the body of liquid. The peripheral edges of the cover assembly extend beyond the edge of the liquid and are resiliently secured by tension cables that are attached to tension towers. The tension cables hold the cover assembly in position on the top surface of the liquid and permit the cover assembly to travel upwardly or downwardly in response to the liquid level. Thus the cover assembly is always supported by the liquid and tension in the tension cables. The elevated wall reservoir system allows existing reservoirs to be modified to increase their storage volume by twenty to fourty percent without the need of utilizing additional land area. The elevated wall reservoir system can also be used on new installations.

Granted: 1995-09-05
Abstract: A method of continuously hot-rolling sheet bars in which a roughly rolled leading sheet bar and a trailing sheet bar are abutted prior to a hot finish rolling step.          Plastic deformation of either or both of the cut rear and front end portions of the leading and trailing sheet bars is applied.   End portions are brought into contact with each other due to metal flow, forming a gap portion between the sheet bars.    The thickness of the sheet bar around the gap portion is enlarged in comparison to the thickness of the contact portions, and hot finish rolling fills the gap so that the bars are strongly joined over their width.
