Abstract: An elongated tool handle has a solid wood shaft member and a molded, tool holding section molded directly to the wood at the tool end portion of the shaft member. The tool holding section is composed of a high impact material which is effective to secure a tool in place on the tool holding section. The tool holding section includes a volumetric mass of high impact material which gives off an amount of heat in its molten condition effective to drive moisture out of kiln dried wood. The wood of the shaft member has an amount of moisture sufficient to maintain the natural handle strength characteristics of the wood with the tool holding end section molded directly thereto. When the tool having an eye for the reception of the handle is placed over the molded, tool holding section, a slight outward expansion occurs in the material behind the tool head. A novel method is required to produce the tool handle with a molded tool holding section molded directly to a wood shaft.

Abstract: The ends of a premeasured length of an elastic, thermoset sheave insert material are laminated together in a special splicing jig for fabricating a unitized insert loop, which is subsequently stretched around a sheave into a preformed insert receiving slot along the circumference thereof. The jig holds the ends of the premeasured length of insert material in alignment as a heated mold, included therein, fits snugly around the ends and applies heat to the joint therebetween, into which the insert material, in liquid form, has been inserted to join the ends. The heat thus applied to the joint accelerates the curing of the liquid into the same consistency as the insert; thereby producing a unitized bond between the ends by which the unitized loop is thus formed.

A relatively low resistivity conductive region having a substantially uniform narrow line width is defined in the polycrystalline layer by effecting a diffusion process to laterally diffuse a doping element into a portion of the polycrystalline layer underlying an edge portion of the masking layer without diffusing the doping element through the insulating layer into the semiconductor body or portion thereof.

Abstract: A method is described for eliminating abnormalities in a polycrystalline silicon integrated circuit structure, such as a silicon gate field effect transistor structure. The layer of polysilicon is deposited on an insulator coating which may be the thickness of the gate dielectric. The polycrystalline silicon is delineated by lithographic techniques and a reactive ion etching process to form the desired conductor structure which would include gate electrodes for the field effect transistor structure. A thickness of the polycrystalline silicon of the order of hundreds of Angstroms is left upon the insulator coating where the masking layer has openings. This thin coating of polycrystalline silicon in the order of hundreds of Angstroms is then thermally oxidized together with the exposed sidewall of the polycrystalline silicon in the areas under the opaque parts of the masking layer to form silicon dioxide on the sidewall of the polycrystalline silicone structures.

The invention applies to the automatic plugging in of electrical conductors.

Abstract: The present disclosure describes a side-loading wire wrapping assembly comprised of a specially configured bit and sleeve, for use on semi-automatic wiring machines. Such machines are used to make solderless wrapped connections on terminals emanating from a common plane. The wire wrapping assembly in present use on many of such machines consists of a fixed sleeve substantially enclosing a spring-loaded bit. The arrangement necessitates front-loading of the bit by the operator--a procedure which is tedious and time consuming. The present invention obviates these difficulties by converting the fixed-sleeve assembly from front-loading to side-loading. This is accomplished by providing in the sleeve, a wire feed aperture in contiguity with a longitudinal slot and of orienting the former with a widened portion of the slit formed in the bit periphery by the wire receiving bore.
