Abstract: S U M M A R Y       Control Device for Electrical Wheelchairs or the Like.                        A  control device for electrical wheelchairs or the  like. with a control lever to be activated by hand, which, by means of  a  universal  joint, is so supported that it can be displaced in any direction desired, and is prestressed into a central resting position by means  of  a  spring.  Two mechanical-electrical adjustment elements are provided, the electrical starting values of which are dependent on their mechanical  settings.  Two mechanical transmission devices each transfer only one of two movements of the control lever in directions essentially perpendicular  to  one  another  to the mechanical-electrical adjustment elements.   The  mechanical  transmission  devices  are  connector  link gearings,  which  can be manufactured simply and inexpensively from thin plates.    The   arrangement  of  the  mechanical-electrical  adjustment elements  can  be  carried  out  as  desired.   On the whole, a very low overall construction height results.

Abstract: 15934a METHOD FOR DETERMINATION OF PITH LOCATION RELATIVE TO LUMBER SURFACES                      ABSTRACT OF THE DISCLOSURE   The invention is a method of assisting lumber grading using an electro-optical scanning system.  A first critical determination is determination of pith position of the log from which the lumber was cut, relative to the scanned faces. This then indicates knot orientation. With knot orientation known, knot size and position data also determined by the scanning system can be used to accurately estimate cross sectional area of the knots. From this point a tentative lumber grade can readily be assigned. Pith position is indicated by a number of factors including wane, knot counts on each of the faces and the presence or absences of spiky faces. A preferred form of scanner is one which measures localized wood fiber angles relative to three orthogonal axes. These fiber angle measurements reveal grain slope disturbances on the lumber which are indicative of many types of defects including knots. The system has been used for grading lumber at speeds as high as 350 m/min. with considerable accuracy.

Abstract: The method fox distortions removal from bended pipes using flame and/or laser heating followed by water ox air cooling, has the task of shaping improvement of banded steel pipes. The method is proper for manually as well as fox a computer aid shape cox rection process. The respective process may be carried out independent of any specialized working place. The method uses adequate equipment for heating/cooling operations such as torches or laser and water nozzles and hacks, clamps for 1. avoiding ox removing the eventual distortions. The level of heating being below the critical transformation point, the integrity of the material structure is ensured. The control of heating is performed with tempil stick or automatically in case of the computerized aid process. The effect of distortions removal from distorted area is obtained applying controlled patch of heating/cooling upon that zone. For an increasing of the distortions removal effect, the method uses external forces applied upon the pipe at the required distorted zone.

Title: Method for processing high elastic modulus polyethylene
Inventor: URYU MASARU
IPC: D06H7/00

Granted: 1993-01-05
Abstract: ABSTRACT   This invention is designed to facilitate machining operations, such as cutting or punching, by taking advantage of thermal properties of high elastic modulus polyethylene. Prior to the machining operations, high elastic modulus polyethylene is heated to a temperature not lower than the melting point of the crystalline fibrils so that the polyethylene of the heated portion revert to a state prior to superdrawing and becomes more readily machinable so that it can be subjected more easily to secondary machining.

Abstract: GLASS FIBER REINFORCED POLY(VINYL CHLORIDE) BLEND WITH     IMPROVED HEAT DISTORTION AND TENSILE STRENGTH              ABSTRACT OF THE DISCLOSURE      A high temperature PVC resin blend is made by blend-ing from 60 to 85 parts PVC with no more than 40 parts of a ("alpha-SAN") copolymer of alpha-methyl styrene ("AMS"), styrene ("S") and acrylonitrile ("AN"), and less than 20 parts by wt additives including stabilizers, antioxidants, lubricants, and processing aids. In addition, an impact modifier may be added. The blend with particularly sized glass fibers, may be thermoformed at an elevated process-ing temperature and pressure, to provide a reinforced composite in which the PVC is covalently bonded to the glass fiber. The composite has a substantially higher HDT and equivalent tensile strength, compared to that of a similarly reinforced, unblended PVC composite, without sacrificing the novel composite's other desirable physical properties. The glass is sized with an aminosilane coupl-ing agent, and, a polymer film former selected from the group consisting of (i) a polymer with a nitrogen-contain-ing repeating unit such as an amine, amide, ureido, or urethane group, and (ii) a dispersible or emulsifiable epoxide polymer, which composite, upon extraction with THF, and a subsequent XPS examination, yields a Cl(2p)/C(ls) ratio of at least 0.91, and more preferably of at least 1.13. Glass fibers, thus sized, provide cohes-ive bonding of the resin, so the composite fails in cohes-ive failure. A unique sequence of mixing the blend ingred-ients with glass fiber provides optimum properties in the composite. The sequence requires formation of a single phase of PVC and alpha-SAN copolymer before dispersing the glass fibers in the blend.

The pump is driven through a releasable coupling by an electric motor disposed above the tank mounted for movement between operative and out-of-the-way positions whereby the pump may be readily removed from and reinstalled in the tank without disconnection or connection of pipe fittings within the tank.  Alternatively, a submersible electric motor may be provided.  In a further form, an electrically driven submersible pump connects the discharge outlet to the tank outlet conduit by a remotely controlled flexible coupling while making a slip-fit connection on the suction side.

To release the extension cord, the user actuates the retaining member causing it to pivot upwardly and free the loop of extension cord, thereby permitting withdrawal of the  cord  from the handle.   The retaining member has a cam surface on its leading edge that is engaged by the loop of cord as it is inserted into the cavity in the handle so that the retaining member will automatically pivot upwardly into the release position to permit the loop of cord to be inserted beyond the retaining member,  and  thereafter  pivot  downwardly  into  the  lock position under the bias of a spring.

Abstract: ABSTRACT      A distinctive method and apparatus for depasiting a pattern of material, such as hot-melt adhesive, onto a substrate comprises a supplying mechanism for forming a first and at least a second substantially continuous stream of the selected material, and a gas-directing mechanism for forming a plurality of gas streams. The gas streams have selected velocities and are arranged to entrain the material streams to impart a swirling motion to each of the material streams as it moves toward the substrate.  A transport mechanism moves the substrate relative to the supply mechanism along a selected machine direction.  A regulating mechanism controls the supplying mechanism and gas-directing mechanism to direct the material stream in a selected path toward the substrate and deposit the material in adjacent semi-cycloidal patterns on the substrate while closely controlling a selected cross-directional positioning of one or more of the deposited patterns.
