Title: Water jet edge trimming station for use in papermaking machine
Inventor: CASPAR ROMAN C
IPC: B26F3/00
Filed: 1997-04-07
Abstract: A water jet edge trimming station for trimming the edges of coated paper during on-machine operation includes backsplash compensating features. The edge trimming station has a cutting station over which the web travels to be cut. The water jet travels along a water jet axis to a point of impingement at the cutting station to cut the web. The cutting station has an effluent receiving aperture at the point of impingement. A negative pressure mixing zone located below the aperture draws effluent by-products or backsplash associated with cutting of the web below the cutting surface of the web. The water jet axis is offset a first predetermined angle chosen relative to a normal axis passing at right angles through the point of impingement to reduce backsplash. The water axis jet is rotated about the normal axis by a second predetermined angle to direct the effluent by-products away from the water jet nozzle and the traveling web. The water jet cutting apparatus has positive air pressure chamber surrounding the nozzle head of the water jet to maintain an air flow over the nozzle head driving effluent backsplash away from the nozzle head.

Abstract: This invention is a method and apparatus associated with safe retraction of medical needles after use. Embodiments are disclosed for self-retracting needle systems for both blood draw, syringe, and catheter insertion systems.  Invention manufacture requires only a minimal number and complexity of parts such that a projected manufacturing cost is potentially low enough to permit the apparatus to be cost-competitive with contemporary non-self-retracting needle systems. Methods for making and assembling each of the disclosed embodiments is also disclosed. One blood draw embodiment can be made with as few as three molded parts. Energy storing, needle retracting and mechanisms comprise elastic tubing (180), and vacuum generating piston parts. In an elastic tubing embodiment, selective, constrictive control of stretched tubing volumes effectively inhibits regurgitant flow from the needle. In all embodiments, needle retraction is a single-handed operation permitting a technician's other hand to be used in wound care. Use of frangible parts permits the apparatus housing to be attached to a needle cover, which, in combination, are used as a transport container to further reduce apparatus costs.

Filed: 1999-02-08
Abstract: The invention disclosed is an exercise device comprising a frame holding a seat above the floor that has a resistance loaded backrest for the purpose of rehabilitating atrophied spinal support muscle through progressive resistance exercise while the spine is under pain alleviating traction. The backrest is resistance loaded for both traction, and extension resistance or flexion resistance. This makes needed exercise possible for those who are hindered from such therapy by spinal compressive related pain. The exercise resistance is transmitted to the patient via a horizontal axis backrest, and can be weighted either positively for back resistance, or negatively for abdominal resistance, at the same time traction is applied from a backrest suspension system applying resistance to the user attached to it in the direction that decompresses the spine.
Patent CA-2216340-A1 (CA)
Inventor: DECKER LAWRENCE H
IPC: G09B21/00
Filed: 1997-09-24
Abstract: A refreshable braille cell display uses a single moving part per tactile element.  Tactile elements, formed from stainless steel tubing, are assembled in densely arranged modules.  Lower ends of the tactile elements extend beneath the modules and are in contact with a pressurized medium.   Shape memory alloy actuators are positioned in the tactile elements, isolated from any motion or flow in the pressurized medium.   When a pressurized medium is delivered through a port in a tactile element, the actuator extends upward, thereby forcing the upper portion of the tactile element through a hole in the user contact surface.  In that state the tactile element indicates information.  When the tactile element is activated, current flows from an electrical contact at the lower end of the tactile element,  through the actuator,  and into the outer tube of the tactile element.   The actuator heats, due to electrical resistance, contracts and exerts a downward force on the pressure medium.  The upper portion of the tactile element is drawn below  the  user  contact  surface,  indicating  the  absence of information.     Distributed  pulse  width  modulation  allows instantaneous power requirements to be minimized, and only low safe voltages are needed to operate the array.  By applying a bias force to all actuators via a common reservoir of either pneumatic or hydraulic pressure, the design is simplified, and reliability is increased.   When integrated with a computer,  the  refreshable tactile array of elements gives users access to full computer generated screens of text and graphical information in real time.

Title: Heat-sensitive composition and method of making a lithographic printing form with it
Inventor: PARSONS GARETH RHODRI
IPC: C08K5/16
Filed: 1997-04-22
Abstract: There is described coated on a lithographic base a complex of a developer-insoluble phenolic resin and a compound which forms a thermally frangible complex with the phenolic resin. This complex is less soluble in the developer solution than the uncomplexed phenolic resin. However when this complex is imagewise heated the complex breaks down so allowing the non-complexed phenolic resin to the dissolved in the developing solution. Thus the solubility differential between the heated areas of the phenolic resin and the unheated areas is increased when the phenolic resin is complexed. Preferably a laser-radiation absorbing material is also present on the lithographic base. A  large number of compounds which form a thermally frangible complex with the phenolic resin have been located. Examples of such compounds are quinolinium compounds, benzothiazolium compounds, pyridinium compounds and imidazoline compounds.
