Patent CA-2268529-A1 (CA)
Inventor: ZANDEN JOHANNES PETRUS ANDREAS VAN DER
IPC: B02C13/286
Filed: 1997-10-10
Abstract: The invention relates to a method for directly and multiply making material collide in an essentially deterministic manner, the material being guided, by a rotating guide member (8) from a central feed, along a guide face (10) and to a delivery end (19), in such a guide manner, that the material leaves the guide member, from an essentially predetermined take-off location, at an essentially predetermined take-off angle and at a take-off velocity which can be selected with the aid of the angular velocity, with the instantaneous angle (.theta.) between the radial line (48) on which the delivery is situated and the radial line (49) on which is situated the location where the spiral stream and the path of the rotating impact member (14) intersect one another being synchronised in such a way that the impact takes place at an essentially predetermined location, at an essentially predetermined impact angle and at an impact velocity which can be selected with the aid of the angular velocity, whereupon the material, when it comes off the impact face, collides with a collision face of a stationary impact member at a collision velocity which is at least as great as the impact velocity.

Title: Latch fastener mechanism for thin sheet materials
Inventor: JOANNOU CONSTANTINOS J
IPC: F16B21/02
Filed: 1999-04-23
Abstract: A fastener for coupling two members together is provided with a rotatable core carried by a first member and a protruding elbow for insertion through an elongated slot in the second member. By rotating the core, the elbow is caused to swing over the outer surface of the second member, adjacent the slot, coupling the two members together. The inner, member-engaging surface of the elbow is tapered to form a ramp-like surface that, with rotation, draws the two members together and fractionally fixes the elbow in its engaged position. The latch core when installed in a tubular first member may be provided with resiliently based, expanding locking members positioned adjacent to the core to secure the latch within the hollow core of the tubular first member.

Title: Membrane-permeable derivatives converted intracellularly into active peptides
Inventor: NACCACHE PAUL H
IPC: C07K1/107
Filed: 1998-01-13
Abstract: The present invention relates to membrane-permeable peptides which are intracellular agonists and/or antagonists of chemotactic factor receptors are rendered hydrophobic through acylation and acetoxymethylation of their amine and acid functional groups. The modified peptides of the present invention are loaded into cells. The acetoxymethyl esters are cleaved by non-specific esterases rendering the peptides active in the intracellular compartments of the cells. The effects of the introduction of transformed specific peptides corresponding to intracellular regions common to the major chemokine receptors are illustrated. These peptides completely inhibited chemotactic factor and chemokine-induced calcium mobilization. Furthermore, leukocytes of mice intravenously injected with these peptides failed to migrate towards chemokines(IL-8).

Patent CA-2285115-A1 (CA)
Title: Fill and pressurization apparatus
Inventor: MASON MURRAY R
IPC: B21D31/00
Filed: 1995-05-17
Abstract: Fill and pressurization apparatus having a sectional fluid conductor (27) having a first section (27a) fixed relative to the surroundings, and a second section (27b) which moves toward the first section (27) to form an enclosure (Fig. 2) through which a high volume flow rate low pressure flow may be passed to fill an adjacent open end of a tube (17) with liquid. Said fluid is passed through an inlet conduit (38), which may be a rigid conduit, to the fixed first section (27a). A seal head (77) insertable into the end of the filled tube (17) has an elastomeric seal member (87) and a rod (76) and a sleeve (78) relatively axially displaceable to compress the seal member (82) and deform it into sealing engagement with a surface of the tube (17). A stop member (84) on one of the rod (76) and sleeve (78) and a stop surface (81a) on the other of the rod (76) and sleeve (78) limit the axial displacement and hence also the compressive force applied to the seal member (82). The relative displacement is achieved by retracting one of the rod (76) and the sleeve (78) and blocking the retraction of the other. The blocking is provided by two telescoping cylinders (89 and 96), one (96) of which has abutments (99) thereon running in channels (101) provided in the other cylinder (89). To effect blocking one cylinder (96) is rotated relative to the other so that the abutments (99) are out of register with the channels (101) and engage stop surfaces (103) in an extended condition of the cylinders (89 and 96) relative to one another.

Abstract: The present invention relates to an automatic respiration system (1) involving positive airway pressure. The inventive device (1) comprises equipment (2) for measuring the breathing gas flow and comparing it with a threshold value. Further equipment (3) is provided for screening any obstructive respiratory impairment. An assessment unit (4) is provided for assessing the measurement values and determines whether it is a case of normal breathing or obstructive respiratory impairment or non obstructive respiratory impairment. Depending on the results provided by the assessment unit (4), the positive airway pressure is either maintained or modified. According to the invention, the breathing gas flow as well as the obstruction of the respiratory tract are continuously measured, thereby enabling the positive airway pressure to be individually adjusted to various states of the patient.

Title: High solids content starch-silicate adhesive compositions for corrugated boxes
Inventor: MILLARD WILLIAM
IPC: C09J103/02
Filed: 1998-05-04
Abstract: Novel starch-silicate adhesive compositions are disclosed which are of particular advantage in the manufacture of corrugated board. By the controlled combination of starch, alkali silicate and, optionally, caustic soda and borax it has been found possible to produce useable adhesives having much higher levels of solids content than conventional starch-based adhesives, thereby allowing for lowered energy costs in use of the adhesive formulation to manufacture boxboard, as well as improved product quality. The formulation of starch-silicate adhesives according to the invention allows viscosity, rheological characteristics - in particular gelation temperature - and the speed of "green-bond" formation to be controlled and adapted to the requirements of modern high-speed corrugating equipment.

Patent CA-2296860-A1 (CA)
Title: Under floor loading system for a crop storage bin
Inventor: SIMROSE PHILIP D
IPC: B65D88/54
Filed: 2000-01-21
Abstract: A crop material is unloaded from a storage bin by providing a generally triangular pit arranged below the base pad surface of the bin into which crop material can fall from the bin through one of two openings in the base floor. Opening the door of one of the openings at the center of the bin allows discharge of the material into the pit by gravity to an apex at a bottom of the pit below the opening.  The pit has a bottom wall inclined upwardly and outwardly to exterior opening outside the bin. An auger standing outside the bin with an inclined auger tube is moved to a position extending downwardly from a top discharge end of the auger to a bottom feed end of the auger which is inserted into the pit through the exterior opening so as to extend to the apex at the bottom of the pit for extracting the material falling into the pit through the center opening. When the bin is emptied so that no more material flows into the pit, a second opening at the wall of the bin is opened thus emptying a path to the center from a door at the wall so that a bin sweep can be inserted to complete discharge of the material through the center opening. One part of the pit is covered by a perforated screen allowing injection into the bin of drying air from the pit.
