Patent CA-2224808-A1 (CA)
Inventor: LANGMANN PETER
IPC: H04L1/18
Filed: 1996-06-21
Abstract: The invention concerns a method of re-sending incorrectly transmitted data (ARQ). To effect transmission between subscriber entities (T1, T2) each of which has at least one transmitting part (1, 10) and at least one receiving part (2, 20), a data stream is divided at the transmitting subscriber's end into data words of predetermined length which are combined to form other data words, the individual data words being temporarily stored in a transmission buffer store (6, 60), optionally transmitted via a transmitter unit (7) and, at the receiving subscriber's end, optionally received in a receiver unit (9, 8) and forwarded after temporary storage in a receiving buffer store (240, 24). An error occurring during transmission is detected and a command issued to the transmitting part (1, 10) of the transmitting subscriber entity, via the transmitter part (10, 1) of the receiving subscriber entity and the receiving part (2, 20) of the transmitting subscriber entity, to re-send the incorrectly transmitted data word. The ARQ re-transmissions of the incorrectly transmitted data are carried out using a predeterminable and invariable proportion of the data words transmitted in an average period.

Abstract: A broker application server for facilitating communication between one or more senders and one or more receivers over a digital packet network. Each receiver receives data in a preferred format. Information identifying the preferred data format of each receiver is stored in a database in the broker application server. The broker application server receives digital packets addressed to a receiver. It extracts data and address information from the packet and optionally decrypts the data. It examines the data to identify the data format. If the data is in the preferred format of the addressed receiver, the broker application server optionally encrypts the data, formats it into a packet, and transmits it to the appropriate receiver. If the data is not in the preferred format of the addressed receiver, the data is transcoded into a common or raw data format and further transcoded into the preferred data format of the addressed receiver before being optionally encrypted, formatted into a digital packet, and transmitted to the addressed receiver.

Patent CA-2235860-A1 (CA)
Inventor: DEEM MICHAEL W
IPC: C12Q1/68
Filed: 1996-10-24
Abstract: This invention provides methods by which biologically derived DNA sequences in a mixed sample or in an arrayed single sequence clone can be determined and classified without sequencing. The methods make use of information on the presence of carefully chosen target subsequences, typically of length from 4 to 8 base pairs, and preferably the length between target subsequences in a sample DNA sequence together with DNA sequence databases containing lists of sequences likely to be present in the sample to determine a sample sequence. The preferred method uses restriction endonucleases to recognize target subsequences and cut the sample sequence. Then carefully chosen recognition moieties are ligated to the cut fragments, the fragments amplified, and the experimental observation made. Polymerase chain reaction (PCR) is the preferred method of amplification. Several alternative embodiments are described which are capable of increased discrimination and which use TypeIIS restriction endonucleases, various capture moieties, or samples of specially synthesized cDNA. Another embodiment of the invention uses information on the presence or absence of carefully chosen target subsequences in a single sequence clone together with DNA sequence databases to determine the clone sequence. Computer implemented methods are provided to analyze the experimental results and to determine the sample sequences in question and to carefully choose target subsequences in order that experiments yield a maximum amount of information.

Title: Peel seal zipper tape
Inventor: THORPE CHARLES C
IPC: B65D33/25
Filed: 1998-06-11
Abstract: A peel seal zipper tape for reclosable plastic bags or packages includes a first and a second mutually interlocking zipper profile disposed on a top surface of a laminated film strip. The top surface is formed by a layer of a sealant material. The laminated film strip also has a middle layer, or core, of a material stiffer than the first and second mutually interlocking zipper profiles, and may also have a bottom layer of a sealant material. In use, the laminated film strip is folded over, and the zipper profiles are interlocked with one another. In doing so, portions of the top surface of the laminated film strip face inwardly, so that the folded film strip may be closed with a heat seal. The outside of the folded peel seal zipper tape, that is, the bottom layer of sealant material is bonded to plastic sheet material from which reclosable plastic bags or packages are made. In the production of the bags or packages, the mutually facing portions of the laminated film strip are sealed together. The resulting seal gives a visual indication of having been broken when initially opened.

Title: Container for receiving and dispensing of particulates
Inventor: HUANG DAIYING
IPC: B65D47/26
Filed: 1998-08-25
Abstract: A particulate receiving and dispensing container having a vessel and a cooperating closure is provided. The vessel has a generally circular mouth with a segmental discontinuity therein.  The vessel mouth is slidably engagable with a grater.  Specifically, with the cylindrical housing end portions of a grater drum when so engaged, the segmental discontinuity is preferably located alongside portions of a hopper housing that are integral with end adjacent to the grater drum housing. After being charged with particulates from the grater, the vessel is separated from the grater and the vessel mouth is associated with a valve equipped closure which cooperates with the segmental discontinuity.  Thus, an operating tab for opening and closing the closure valve moves in a depression in the closure.  The depression in the closure fits into and over the segmented discontinuity.

Patent CA-2247874-A1 (CA)
Inventor: MILLER DWAYNE R J
IPC: H01S3/11
Filed: 1998-09-23
Abstract: A variable output coupling laser has the ability to "store-up" pump energy between output pulses, but not suffer from an output pulse profile which is determined solely by the opening time of the Q-switch and the depletion of gain from the laser rod.  This invention allows almost complete control of the intensity, pulse duration and pulse envelope from a laser over a range from 100 nanoseconds to microseconds. The device has two 100% reflecting mirrors and a Pockels cell used to rotate the polarization in a controlled way so as to achieve a precisely controlled degree of output coupling. Hence applying a very short high voltage pulse can result in a system operating like a Q-switch. A lower voltage pulse results in a high threshold laser which will produce only a low intensity pulse, and leaves gain in the medium which can later be extracted by applying a somewhat higher voltage pulse.

Title: High resolution radiation imager
Inventor: POSSIN GEORGE EDWARD
IPC: G01T1/20
Filed: 1998-10-01
Abstract: A radiation imager includes a photosensor array that is coupled to a scintillator so as to detect optical photons generated when incident radiation is absorbed in the scintillator. The imager includes an optical crosstalk attenuator that is optically coupled to a first surface of the scintillator (that is, the surface opposite the photosensor). The optical crosstalk attenuator includes an optical absorption material that is disposed so as to inhibit reflection of optical photons incident on the scintillator first surface back into the scintillator along selected crosstalk reflection paths. The crosstalk reflection paths are those paths oriented such that optical photons passing along such paths would be incident upon photosensor array pixels that are outside of a selected focal area corresponding to the absorption point in the scintillator.     The imager further may include an optical screen layer that is optically coupled to the scintillator second surface so as to be disposed between the scintillator and the photosensor array. The optical screen layer is made of a substantially transparent material selected to have a critical index of refraction so as to cause preferential reflection of optical photons that are incident on the screen layer to reduce optical crosstalk.

Abstract: A hot dip coating system comprises a bath of molten coating metal contained in a vessel having a strip passage opening located below the top surface of the bath.  A metal strip is directed along a path extending through the strip passage opening and through the bath of molten coating metal, to coat the strip.
