Abstract: The present invention is directed toward a bead securement device comprising a tension spring, a first cover and a second cover. The first cover and the second cover are removably secured to the tension spring. In use, a force is exerted on the spring through the covers causing the spring to deform and the gaps between the plurality of coils on the spring expand. Once expanded, the filament may be passed in between one of these gaps so that when the force exerted on the end members of the spring is released, the filament is squeezed between the coils of the spring and held in place. The filament can be easily removed by using the covers to manipulate the end members of the spring.

Abstract: A design board container enabling the arrangement and temporary positional securement of beading elements is provided. The container includes a base member and a lid member preferably in hinged relationship with one another. The base member and lid member include a design liner and lid liner, respectively, formed of a resiliently deformable and preferably compressible material. The liners are preferably substantially planar, i.e., a flat surface, so as to allow for free form designing unconstrained by preset channels. By closing the container, the lid surface engages the design surface and beading elements such that the beading elements deform the design liner and are positionally secured between the design liner and the lid liner. The surfaces of the lid liner and the design liner preferably comprise gripping members, such as filamentary or hair-like elements.

Abstract: A portable workstation for beadcrafting operations is provided. The workstation includes a base including at least one receptacle for holding parts such as beads, preferably in a desired pattern. A cover interfittable with the base includes a seal portion that engages and surrounds the receptacle so as to maintain the parts in their desired position, despite movement of the workstation.

Abstract: High-toughness, high-wear resistance cutting tool based on alumina are formed by additions of zirconia and optionally refractory metal carbides or nitrides.

Abstract: Extremely tough, strong and wear resistant cold pressed and sintered inserts consisting essentially of from about 4 to 20% zirconia, from about 1-15% titanium diboride, and up to about 10% grain growth inhibiting sintering aid with the balance being alumina.

Abstract: A chipbreaking insert for metalcutting is useful for breaking chips over a wide range of speeds and feeds. In light cuts, the chips are broken by a finishing depression adjacent to the cutting corner. In deeper but still moderate cuts, the chips and broken by a chipbreaking groove which is parallel to the cutting edge. In heavy cuts, the chips are corrugated and deflected away from the workpiece by a series of cylindrical chip deflecting grooves spaced along the cutting edge.

Abstract: A cutting tool material having a surprising combination of toughness, high speed wear resistance, strength, resistance to chipping, and resistance to thermal fatigue, consisting essentially of: 15 to 25% of a nickel cobalt binder; 3 to 6% molybdenum carbide; 2 to 5% VC; 15 to 25% TiC; 30 to 40% TiN; and 15 to 20% WC by weight.

Abstract: An indexable insert broach for finishing a cylindrical surface is disclosed. The inserts are mounted on the body of the broach in helical arrays of increasing radii.

Abstract: Serious racers strive to squeeze as many revolutions per minute as possible out of their engines. They often use exotic metals like titanium in efforts to minimize the weight of some reciprocating parts. Almost exclusively, serious racers use titanium valve spring retainers to obtain higher speeds. This invention relates to an improved valve spring retainer for use in high performance engines. More particularly, it relates to an aluminum valve spring retainer which is lighter and less costly than titanium retainers of approximately equivalent strength.

Abstract: A limited rotation roller tappet having an aperture and a slot formed in it. A locking bar having a narrow end portion and a shoulder portion prevents rotation of the tappet. The end portion of the locking bar is adapted to pass through both the aperture and the slot while the shoulder portion will not pass through the aperture. The locking bar preferably has a second narrow end portion and is held in place by a second similar roller tappet adjacent to the first having a slot through which the second end portion passes and an aperture through which the shoulder portion will not pass.

Abstract: A device for scrubbing surfaces having two crank-rocker mechanisms wherein a scrubber element is mounted on the rocking link of each crank-rocker mechanism, the scrubber elements having recessed portions arranged so that as the crank-rocker mechanisms operate, the scrubbers scrub overlapping areas but do not collide.

Abstract: A device for scrubbing carpets having a scrubber which rotates about a point which is driven in a circle wherein the scrubber is pivotably mounted on a frame and the weight of the device is supported by the scrubber and two wheels at the rear of the frame. A press bar may be included at the front of the machine for pressing powdered cleaning composition into the carpet.

Abstract: A device for scrubbing carpets having an augularly oscillating scrubber mounted on a frame.

Abstract: A method of dyeing synthetic fibers, especially polyester and acrylic using an aqueous dyeing admixture containing a halogenated hydrocarbon solvent, an aromatic carrier, an emulsifier and a dyestuff.

Abstract: A water jet loom having means for forming a shed including heddles upon which warp yarns are mounted, a weft inserting jet for inserting weft yarns into the shed, a stainless steel reed for beating the weft yarns into the apex of the shed and means for supplying alkaline feed water to the weft inserting jet is disclosed.

Abstract: Fibers are dyed by applying an aqueous dyeing formulation to the fibers, cooling them and condensing halogenated hydrocarbon vapors upon the cool, wet fibers. Residual halogenated hydrocarbon is removed by exposing the fibers to heat.

Abstract: The pile is trimmed from selected regions of pile fabrics by applying stiffening agent to the regions from which the pile is to be trimmed, this stiffening agent is then hardened and the fibers thereof are then severed from the regions to which stiffening agent was applied by drawing the fabric past a cutter having a blade which allows the fibers in the untreated regions to deflect out of its path but severs the fibers to which stiffening agent has been applied. Residual stiffening agent is then removed by scouring.

Abstract: Polyethylene glycol added to semi-dry powdered cleaning compositions to prevent adhering of fine particles of the cleaning powder to the fibers being cleaned.

Abstract: A device for scrubbing surfaces having pairs of freely rotatable brushes each mounted on a shaft having an offset tip portion. Each shaft is mounted on a rotating support plate and half of the shafts rotate clockwise and the other half rotate counter-clockwise. In the preferred embodiment, the scrubbers have slanted bristles which bias the rotation of each scrubber in the direction of rotation of the shaft it is mounted upon. The preferred embodiment is particularly well suited for use in cleaning carpets using the powdered cleaning composition described in U.S. Pat. No. 4,013,594.
