Abstract: A process for the production and further processing of strands for Bowden cables of several wires stranded together by twisting, comprising dressing the strands after stranding between reversing rolls, subsequently stretching and again dressing between reversing rolls. Dressing is effected prior to stretching in several stages with decreasing bending radii and after the stretching again in several stages with increasing bending radii, while the stretching is performed with a force approximately within the area of the elastic limit, corresponding to 45% to 70%, preferably to 55% and 65% of the ultimate tensile strength of the strand.

Abstract: A tractor supported and driven mechanism for removing tree stumps which causes linear movement of a rotary cutter disk for milling away stumps from the side portions thereof is disclosed. The mechanism incorporates a frame structure having a hydraulically driven slide supported and guided by parallel structural members of the frame. The cutter disk is rotatably supported on the slide structure and is driven by the power take-off of the tractor by means of an elongated non-circular drive shaft which is received in driving engagement by a central non-circular drive opening of the cutter. The cutter disk is movable along the length of the non-circular drive shaft while maintaining driving engagement therewith. The hydraulic system of the apparatus is a closed loop system independent of the tractor hydraulics.

Abstract: Square or rectangular clean cut flakes, wafers or strands of a uniform thickness, width and length, with edges extending at right, acute or obtuse angles to the surfaces are produced by an apparatus in four distinct operations, comprising the veneer slicing, cutting of the veneer sheets into veneer strips, chemical or laser beam treatment and flake cutting. The chemical or laser beam treatment is applied to the edges of the veneer strips which run transversally to the direction of wood fiber and the application takes place before the veneer strips are cut into flakes.

Abstract: A mechanical log splitter in which relative motion is imparted between a cleaving blade and a log longitudinal the axis thereof and the log is split by the cleaving blade being forced thereinto. All moving parts of the log splitter disclosed, except for a log-impelling block that forces each log onto the cleaving blade, are enclosed for safety reasons within an elongated support frame which is preferable made of metal pipe. Riding within the support frame, supporting the log-impelling block and releasably secured thereto to facilitate maintenance, is an elongated carriage, which may also be cylindrical. An activating means housed within support frame at one end of the cylinder drives the carriage and log-impelling block to splitting logs against the cleaving blade of the device. The cleaving blade comprises an elongated tapered body portion of either conical or pyramidal shape having the apex thereof directed toward the approaching log and a longitudinal axis parallel to the motion thereof.

Abstract: A rigid wooden composite assembly such as a beam, post or the like, includes a plurality of elongated wooden boards of varying lengths disposed in face-to-face relationship and forming a plurality of layers. At least one of the layers includes a plurality of boards, the inner ends of which abut to form a joint therebetween. A connector device has a base plate with openings therein. Prongs extend outwardly from the plate and initially generally normal thereto. The prongs of adjacent openings extend in opposite directions from the plate. The connector device is disposed between the layers so that the base plate bridges the inner portion of the joint and the oppositely extending prongs penetrate the opposing board faces. When the assembly is compressed together, the prongs deform and clinchingly engage the wood surrounding the joint. The abutting boards are spliced together, and the facing boards are held tightly together.

Abstract: A fence machining device for beveling and machining portions of lengths of wood to be used as a portion of a fence. A length of pre-cut lumber is clamped to a work table having an upright frame secured near one end of the lumber. A glidable and pivotable plate is coupled with the upright member such that a rotary cutter, affixed to the tray, can be moved in a vertical direction of selected distance so as to notch the lumber a preselected distance and the same cutter is permitted to describe an arc through a free end of the lumber so as to round off a corner of the lumber. The lumber may be turned over and the procedure repeated to produce thereby a double notched and tapered end of lumber for use in fence constructions.

Abstract: A device for a woodworking machine (13) adapted at a number of consecutive working stations (14) for processing workpieces which are fed through the machine. The required working of the workpieces can be effected with at least one working station out of operation. The working stations are separated from each other by partitions (20) which extend between external walls (11), a roof (12) and a base and which are closely associated with the machine on either side of the working stations (14) and, like the external walls and the roof, are sound-proof. The tool or tools at each working station can be driven independently of the tools at the other working stations, and each compartment (22) defined by the partitions has a door (21) in the external wall (11). The path of travel of the workpieces through the machine is laterally limited by vertical walls and at the working stations the walls can be provided with covers for forming tunnel portions at these locations.

Abstract: An insulating material plate (4) is fixed to the surface (6) of a structure (8) by a dowel (2) with a disk-like head (14), countersunk in a countersunk hole (24) of plate (4) and carrying on its outer surface an insulating material washer (10). Washer (10) prevents the thin plaster layer (22) from separating at the location of dowel head (14), due to the thermal expansions and differing thermal conduction between the dowel material and the mortar material. The insulating material washer (10), which is e.g. made from the same material as the insulating plate, also makes it possible to level the outer surface (20) of the insulating material plate by abrasion, prior to the application of the mortar layer, so that a smaller thickness of the latter can be used.

Abstract: A hand-held router is provided that includes a motor with a router bit mounted on the motor in driven relationship. A router head is attached to the motor an at least partially surrounds the router bit. A device for controlling the depth of cut of the router bit is mounted on said router head as is a device for adjusting a second parameter of the cut. In one embodiment, the second controlled parameter is the width of cut made by the router bit. Preferably, a guide block is also movably affixed to the cut width adjustment device and acts as a guide to maintain the uniformity of cut of the router bit. The guide block is adjustable to accommodate workpieces of different thickness. In a second embodiment, the second controlled parameter is the angle of the cut. The router head is adapted for receiving an angular adjustment plate that can be used to determine the angle of attack of the router bit on the workpiece.

Abstract: Effluent treatment for the woodrooms of wood processing industries, e.g. paper and pulp mills, wherein the water separated from the bark and containing fibres is passed back onto an existing conveyor of wet bark, provided with a perforated bottom, so that some of the fibre contained in the water is filtered and mixed with the bark and passes along with the bark to dewatering.

Abstract: A system is described for processing an entire tree into wood fiber material for molding the constituent wood elements into custom molded wood products. A delimber removes limbs and leaves from the trunk, a debarker removes bark from the trunk of the delimbed tree, and a splitter separating sequence is constructed and arranged for separating the debarked trunk into elongate pieces of substantially equal cross-sectional area. A graduated roller mill having a sequence of pairs of compressor rollers with the rollers of each pair spaced successively closer together receives the elongate pieces of wood and extrudes and delivers thin sheets of wood at the output end. Liquid squeezed from the wood sheets is collected and separated into resins and water. A shredder shreds and fragments the wood sheet wood fibers into a loosely bonded mat of substantially separate striated wood fibers. The mat is cut or chopped into wood fibers of substantially uniform length.
