Patent number: 4919987Abstract: A process and means for joining polyamide parts by friction welding, whereby the particles, called "turnings" formed and expelled from the welded joint are captured. In the production of many containers composed of relatively hard polyamides, having melting points above 250 degrees Celsius, it is necessary to prevent the turnings from falling into the inside of the container. This is particularly true when the turnings cannot be rinsed or sucked from the interior with relative ease or minimal cost, such as when walls, ribs or chambers are present inside the container. In the past, recesses have been provided near the joint to collect the turnings, however, such recesses did not prevent all turnings from being thrown into the interior of the container.Type: GrantFiled: January 14, 1988Date of Patent: April 24, 1990Assignee: Verwaltungsgesellschafft Geiger Plastic GmbH & Co.

Patent number: 4698250Abstract: The invention relates to a method for the manufacture of a press felt for a paper machine and a press felt manufactured by means of said method. The method comprises the manufacture of a seamed fabric and the needling of a fibrous layer on at least one side of the seamed fabric. the fibrous layer is incised in such a way that the seam of the seamed fabric can be opened by removing a connecting thread and correspondingly rejoined after the press felt is mounted in the paper machine by passing the connecting thread back in place so as to join the press felt into an endless loop. In order to eliminate the marking caused by the seam, and in order to increase the water space, at least one surface fabric is provided on at least one surface of the seamed fabric between the seamed fabric and the fibrous layer. The incision of the fibrous layer is made through the surface fabric/surface fabrics up to the seamed fabric.Type: GrantFiled: October 31, 1986Date of Patent: October 6, 1987Assignee: Tamfelt Oy AbInventors: Tauno Talonen, Riitta Niemi

Patent number: 4695502Abstract: Interlocking landscaping planking wherein the opposite edges of each interlocking plank has a tongue and groove of special shape and relative dimensions to permit maximum flexibility in assembling curved landscaping arrangements consisting of multiple numbers of the planks joined side by side. The novel trapezoid or circular shaped tongue is centered vertically is one edge of each interlocking plank, its base indented slightly from the front and back surfaces of the plank to permit and to limit the lateral movement of the plank. The exterior surfaces of the tongue slope or curve inwardly, tapering to a flat apex. The novel trapezoid or circular shaped groove complements the novel trapezoid or circular shaped tongue, but spaced slightly therefrom and is centered vertically in the opposite edge of the plank, its mouth indented slightly from the front and back surfaces of the plank to permit and to limit the lateral movement of the plank.Type: GrantFiled: July 23, 1986Date of Patent: September 22, 1987Inventor: John L. Rush

Patent number: 4649069Abstract: A rectangular tile-like carpet is disclosed, the body of which has front and back pile layers. Both front and back sides of the carpet can be used, so that the frequency of cleaning the carpet can be reduced to save expenditure and labor. Also, the two pile layers increase the cushioning property of the carpet. Further, the front and back pile layers may have different colors to permit different colors be enjoyed by merely inverting the carpet.Type: GrantFiled: May 8, 1985Date of Patent: March 10, 1987Assignee: Saami Co., Ltd.Inventor: Yasuyoshi Tone

Patent number: 4584222Abstract: Glued laminated wood which has a novel laminated structure and may be fabricated from small-sized veneer sheets, and method of manufacturing such laminated wood are provided. The glued laminated wood in its continuous form is made from a series of unit-length veneer sheets each having the same length and thickness which are laminated in a laid-up arrangement in which each of the veneer sheets is lapped on another and offset therefrom in the direction of its length at a regular interval determined by the number of plies to be in the laminated wood product and the length of the unit veneer sheets. It has a novel structure in that each veneer sheet therein has tandemly spaced straight length portions which are parallel to each other, but successively displaced from each other in the direction of the thickness of the product, there being a somewhat S-shaped curved length portion of the veneer sheet between any successive pair of these straight length portions.Type: GrantFiled: November 9, 1984Date of Patent: April 22, 1986Assignee: Meinan Machinery Works, Inc.Inventor: Masakuni Iwamoto

Patent number: 4568584Abstract: A garden structure includes a plurality of adjacent plastic base members with each of the base members including a frame portion, a filler portion, a sealing portion and a fastening portion. The frame portion includes spaced substantially flat major sections, sections having substantially the same configuration and being disposed substantially parallel to each other. Sidewall sections extend between adjacent peripheral edges of the major sections and at least two opposed sidewall sections are substantially parallel to each other throughout their lengths. The spaced major sections and sidewall sections together form a cavity within the base member. The filler portion includes particulate material compressed within the cavity of the base member and filling same. The sealing portion includes an opening in one sidewall of the base member and a cover section engageable with and completely enclosing the opening.Type: GrantFiled: November 20, 1984Date of Patent: February 4, 1986Inventor: Don A.
