Abstract: TITLE          WINDOW SASH COUNTERBALANCE WITH VARYING LIFT            ABSTRACT           A counterbalance for a window sash (28) includes a torsion spring (10), a follower nut (20), and a spiral rod (22) threadably engaged with the follower nut (20).  The spiral rod (22) has a pitch that is varied along one part of its length to produce a substantially constant lifting force throughout most of a range of sash travel between a lowered position and an intermediate position.  However, the pitch is further varied along another part of the length of the spiral member to produce a larger lifting force within a remaining portion of the range of sash travel from the intermediate position to the raised position.

Abstract: METHOD AND APPARATUS FOR THE PRODUCTION OF SHEETS OF FIBROUS MATERIAL TO IMITATE A POROUS STRUCTURE OF NATURAL WOOD Abstract of the Disclosure A method and apparatus for the production of sheets of material to imitate a porous structure of natural wood. According to the invention, the porous structure of a sample surface of a sheet of natural wood is analysed, taking information from it regarding the coordinates of characteristic points of the lines representing the individual pores. Said information is then stored in a process logic unit comprising a computerised design program, providing data which indicate the dimensions of the pores to be formed. The data and information are then converted into control signals for a computerised engraving system which reproduces this porous structure by engraving it on a sheet of fibrous material. The sheet of porous material made in this way can be used directly for facing or decoration or for creating an artificial veneer.

Title: Atrial defibrillator and method for setting energy threshold values
Inventor: AYERS GREGORY M
IPC: A61N1/39
Filed: 1994-01-04
Abstract: An implantable atrial defibrillator cardioverts the atria of a patient's heart and determines the quantity of cardioverting electrical energy required for cardioverting the atria of the patient. The atrial defibrillator includes a detector for detecting atrial activity of the heart and an atrial fibrillation detector for determining when the atria of the heart are in fibrillation. A delivery stage is selectively operable in a test mode for applying fibrillation inducing electrical energy to the atria when the atria are not in fibrillation for inducing fibrillation. When fibrillation is induced, the delivery stage repeatedly applies test cardioversion electrical energy to the atria until the atria are cardioverted.      Thereafter, a value indicative of the quantity of the test cardioversion energy last applied to the atria is stored for future reference when the atrial defibrillator is in a normal operating mode.

Patent CA-2122810-A1 (CA)
Inventor: WINTER DAVID C
IPC: A01B63/22
Filed: 1994-05-03
Abstract: A one-way pressure bleed off path is provided between the series cylinder depth control circuit and an additional hydraulic circuit for an agricultural implement to prevent pressure build-up and hose expansion that otherwise would cause uneven series cylinder extension and uneven implement depth.  A line including an orifice and a one-way check valve is added between the depth control circuit and the second circuit, such as the wing fold circuit for the implement, to bleed off any series cylinder pressure build-up through the otherwise unused second circuit.  The  orifice limits the amount of oil that is returned to reservoir during operation of the series circuit to lower the implement.  The check valve isolates the depth control circuit and the second circuit to prevent unwanted cylinder operation while the wings are being folded.

Filed: 1995-03-24
Abstract: A method for wrapping a wrapper about a floral grouping wherein the wrapper is a sleeve or sheet of material having a cinching tab or strip of bonding material or both and a detaching means such as perforations for detaching a portion of the sleeve or sheet of material. The floral grouping is placed on the sheet of material which is wrapped thereabout, or the floral grouping is disposed in the interior space of the sleeve. The cinching tab is attached near one end of the sheet or sleeve. The cinching tab has a bonding material disposed thereon which, when the cinching tab is pulled tightly about the wrapper, causes the wrapper to be crimped and tightly bound about the stems of the floral grouping. When a sheet or sleeve having a strip of bonding material is used, the portion of the wrapper having the strip of bonding material is crimped manually or automatically about a portion of the stems of the floral grouping causing portions of the wrapper to overlap and bond to each other causing the wrapper to be held firmly about the stems of the floral grouping. The wrapper may further comprise an additional strip of bonding material for bonding an informational card or label to the wrapper. After the wrapper is wrapped about the floral grouping, a portion of the wrapper may be removed by using the detaching means, thereby leaving a portion of the wrapper wrapped or bound about the floral grouping.

Title: Use of relaxin as therapeutic or preventing agent
Inventor: BIGAZZI MARIO
IPC: A61P9/00
Filed: 1994-07-26
Abstract: Relaxin (RLX), a peptide hormone of the insulin family, has been found to produce impressive effects on the walls of blood vessels, on the blood clotting and on blood lipids and electrolytes, "per se," and through the stimulation of the synthesis and release of the two powerful substances: Nitric Oxide (NO) and Atrial Natriuretic Peptide (ANP). Experimental studies have shown that administration of RLX increases the blood flow and produces dilation of arteries, influences blood clotting and fibrinolysis and reduces blood lipids. RLX also induces reduction of blood osmolarity and sodium concentration. At the same time, through NO RLX inhibits release of histamine from mastocells. Therefore RLX is proposed as a therapeutic agent to be used in arteriosclerosis and vascular diseases, ischaemia and thrombosis, hypertension and pregnancy's gestosis. Finally, RLX can also be adopted in other diseases by NO as allergic and inflammatory disorders or by ANP as disfunctions in fluid and electrolytes balance.

Patent CA-2148901-A1 (CA)
Title: Soccer Game Apparatus
Inventor: YING RAY C
IPC: A63F7/06
Filed: 1995-05-08
Abstract: The sport of soccer is simulated with the aid of a representative playing field, a game ball, representative general athletes and representative goalkeepers. The general athletes are constructed from a resilient material such as cardboard, plastic, or sheet metal and are characterized by a concave-down shape defined by a leading member and a trailing member that are resiliently connected. In play, a general athlete is placed adjacent to the game ball such that its leading member abuts the ball. The player makes the athlete kick the game ball by striking a downward blow to the resilient connection, thereby propelling the leading and trailing members outwards and upwards and driving the abutted ball forwards. A goalkeeper is constructed much like the general athlete except that it bears a first magnet. The player uses a second magnet on a control rod to drag the goalkeeper around the playing field by the first magnet.

Title: Liquid spill containment system and method for its manufacture and use
Inventor: GREGORY DAVID B
IPC: E03F1/00
Filed: 1995-05-10
Abstract: A portable liquid spill containment has an endless containment wall fabricated from closed-cell foam that encircles a spill containment area and has an elastic memory that enables the material to recover its shape fully after each of repeated deformations.  A top layer of elastomeric polymer compound is formed to the shape of the containment wall and is reinforced with woven fabric to provide a reinforced, liquid-impervious, seamless and foldless top membrane that lines the containment area and extends up and around the containment wall.          A bottom layer of the same elastomeric polymer compound is united to the underside of the top membrane to encapsulate the containment wall therebetween.  In use, the containment is positioned in an area where liquid to be contained is being handled.  Wheeled vehicles, such as fuel delivery trucks, may enter the containment area simply by driving over the resiliently deformable containment wall.  Any spills are contained within the confines of the containment wall.  Prior to the vehicles exiting over the containment wall, the spilled liquid is removed.
