Patent CA-2026469-A1 (CA)
Title: Apparatus and method for collecting shellfish and the like
Inventor: KIRKMAN KENNETH G
IPC: A01K80/00
Filed: 1990-09-28
Abstract: Apparatus and Method for Collecting Shellfish and the Like Abstract A new scallop net is disclosed that uses a lightweight frame that is fitted with a dive plate that procedures a downward force on the frame and ensures that the frame remains on the bottom.  Instead of a heavy metal basket, the device includes a standard skein netting made of nylon of similar material.  The net has a splitting strap in the middle of the bag and is fit-ted with a cod end and a cod end release, which opens the bag when the strap or release is pulled.      Because the bag is fitted with a cod end, the steel frame does not have to be pulled onto the boat.  The dangerous frame can be raised on a boom and left overhanging the boat.  The splitting strap can then be used to pull the light net bag aboard, the cod end release can be pulled and the catch re-leased.  Once emptied, the cod end can be re-secured, the re-lease mechanism can be reset, and the net thrown overboard. The frame end can then be released back into the sea for anoth-er run.  Two bags can be dragged in this manner for optimum collection.  Alternatively, a single bag can be supported from an A-frame support member suspended form the stern of the ves-sel.

Abstract: A medication dispenser includes a reusable container adapted to receive one or more disposable multicompartment liners for sanitary storage of medication out of contact with the reusable container. The open-topped compartments of the liner are closed by individual covers which are locked onto the container with a fracturable tab which must be broken to open a compartment. The covers are designed to form at least a Class B closure with the liner compartments for tamper-proof sanitary air-tight storage of a patient's medication. When the liners are removed, the broken tabs from the covers may be dumped from the compartments.

Title: Wheeled container for large tube transport and way to unload it
Inventor: MARCU MIHAIL I
IPC: B65G47/96
Filed: 1991-01-29
Abstract: WHEELED CONTAINER SYSTEM FOR LARGE TUBE TRANSPORT                AND WAY TO UNLOAD IT                          ABSTRACT          A new wheeled container for large tube transport and a way to unload it is proposed based on gondolas supported by spherical joints having the centre of gravity under the axis formed by the spherical joints, these spherical joints being on wheel bogies rolling on a tubular guideway; attached to these wheel bogies  there are  articulated some  arms/elbows with heavy rollers   pressed  on   the  tubular  guideway  by  spring arrangements;  connected to the said arms/elbows there are flexible jacket cables connected in a desmodromic way with arms/levers with rollers on the bogies and on the gondola; when the tubular guideway is enlarged laterally, the heavy rollers will expand (cause of the spring arrangements) and will  pull out of the gondola space  the arms/levers with rollers which in turn enter in guides straight or helical to do the function of unloading of the wheeled container; the arms with rollers associated with the gondola remain vertical because the centre of gravity of gondola is below the axis of rotation formed by the said spherical  joints;  this makes possible the separation of the arms/levers with rollers of gondola and wheel bogies.

Title: Indexing linkers
Inventor: DEUGAU KENNETH V
IPC: C12Q1/68
Filed: 1991-02-22
Abstract: Synthetic nucleic acid molecules are provided which are called indexing linkers and which can be selectively linked to unknown, or non-identical cohesive ends of nucleic acid fragments.      Such indexing linkers are useful for the selective isolation, identification, amplification, labelling, and modification, of nucleic acid fragments, especially subsets of such fragments released by cleavage using Type IIS restriction endonucleases or restriction endonucleases recognizing interrupted palindromic sequences. Sets of such indexing linker molecules are described which are useful for indexing fragments released by cleavage of a genome. Methods are described for distinguishing such fragments using said indexing linker molecules fox effecting detection, or further modification of such fragments; and for amplifying such fragments by the polymerase chain reaction.

Title: Redundant fluidic multiplexer
Inventor: SNOW BARTON H
IPC: G05B19/414
Filed: 1991-07-11
Abstract: ABSTRACT OF THE DISCLOSURE      The reliability of a fluid multiplexed actuation system is increased by arranging a pair of fluidic multiplexers in a parallel fluid flow path between a selector valve and several fluid actuators.  Position sensors associated with the fluidic multiplexers and with the fluid actuators provide feedback signals to a microprocessor.  In the event the feedback signals identify a malfunction in the fluidic multiplexer currently supplying fluid to the actuators, the microprocessor will deactivate the malfunctioning fluidic multiplexer and activate a redundant or back-up fluidic multiplexer by actuating the selector valve.

Filed: 1991-09-09
Abstract: DUAL ORIFICE NOZZLE AND METHOD FOR INTERNALLY COATING CONTAINERS                     Abstract A nozzle, nozzle assembly and method for internally coating containers uses a dual orifice nozzle and method to direct divergent spray patterns at separate interior surface portions of the container where the coating liquid is most needed and to minimize misting, overspray and waste.  The nozzle comprises a generally cylindrical body having a forward portion, a middle portion, a rear portion, a first conduit extending longitudinally therethrough terminating in a first opening disposed in the forward portion, and a second conduit extending longitudinally therethrough terminating in a second opening formed in the forward portion of the body.  The first and second openings are oriented at an acute angle with respect to a central longitudinal axis of the nozzle to direct the separate sprays of coating liquid from the body generally in separate patterns diverging from the central longitudinal axis of the nozzle.  The conduits are suited to receive airless nozzle inserts that direct the separate spray patterns at the distinct interior portions.  In the internal coating method, a flow of coating liquid is divided into first and second flow portions, with the first flow portion directed toward one interior surface portion of the container and the second flow portion toward another separate interior surface portion.

Abstract: A web is reeled onto successive reeling drums to form respective jumbo rolls by reeling the web onto a first reeling drum at a reeling position to form a first jumbo roll, the first reeling drum being driven by a center drive.      When the first jumbo roll is full, a second reeling drum is delivered to a standby position and is accelerated to web speed. A transfer device is employed to transfer the first jumbo roll to an exchange position while the canter drive remains connected thereto. The second reeling drum is transferred to the reeling position and the web is exchanged from the first jumbo roll to the second reeling drum. The first jumbo roll is decelerated and the transfer device is shifted from the first jumbo roll to the second reeling drum. The center drive is connected to the second reeling drum.

Title: Surfaces having desirable cell adhesive effects
Inventor: HUBBELL JEFFREY A
IPC: C12N5/079
Filed: 1990-09-27
Abstract: An absorbed protein-independent cell-adhesive surface is disclosed. The treated surface comprises a chemically derivatized material to which small peptides, having less than 12 amino acid residues and including YIGSR, RGD or REDV amino acid sequence are covalently linked to. The peptides of the present invention include a terminal glycine amino acid. Tresyl chloride activation of surface hydroxyl moieties provides the active surface sites by which a terminal glycine arm of a selected peptide attaches to form covalent bonds between the substrate and peptide. By way of example, surfaces which may be used in conjunction with the present invention include polymer, metal, and ceramic surfaces. The present methods also include a pretreatment method which provides hydroxyl moieties to surfaces devoid of readily available hydroxyl moieties.  Methods of preparing the treated surfaces are also included in the present invention. Also included are surface-treated biomedical implant devices and cell culturing devices. The treated surface promotes an enhanced rate and an enhanced amount of cell adhesion to the surface, independent of media serum concentrations or other absorbed proteins. The invention further concerns polymeric substrates with a surface having physically interpenetrating water soluble polymer chains, and methods for production thereof.
