Abstract: Method of making a self-locking threaded element, e.g. a screw including a strongly adhered convexly curved plastic body on its threaded surface allowing smooth assembly and giving strong frictional engagement between the element and a mating threaded surface. In the method, a stream of fine particles of heat-softenable plastic is directed against a threaded surface portion of a heated metallic element. Contacting particles are caught on the heated surface and fused by heat from the element to form a continuous plastic body which is then hardened by cooling.

Abstract: A packing machine for cigarettes comprises a number of rotatable drums which are driven intermittently. Carton blanks and foil-wrapped bundles of cigarettes are fed by separate transfer drums to a common wrapping drum, which has pockets into each of which is inserted first a blank and then a cigarette bundle. Partial folding of the blank occurs while it is on the blank transfer drum, further folding as it is inserted into a pocket of the wrapping drum, and yet further folding after insertion of the cigarette bundle. The blank is partially gummed before it reaches the blank transfer drum and further gumming is effected on a further drum to which the cigarette bundles with their (now folded) blanks are transferred from the wrapping drum.

Abstract: The specification discloses a method of making an aperture-defining frame member, particularly a window-frame, comprising a rigid frame-shaped reinforcement made of e.g. a solid metal section embedded in synthetic resinous material. The method comprises placing the reinforcement in a mould cavity having the shape of the required frame member and locating the reinforcement in the cavity solely by engaging complementary interfitting formations on the reinforcement and on pin-like projections which extend from the cavity walls, e.g., recesses on the reinforcement engaging the ends of the projections. The longitudinal axes of all the projections are parallel to a predetermined plane and the engagement of the end of each projection with the complementary recess of the reinforcement prevents movement of the latter at least in first directions perpendicular to the plane. The projections are located around the reinforcement to prevent movement of the reinforcement in second directions parallel to the plane.

Abstract: A tool for reconditioning threads on vehicle lug studs. The tool is comprised of a hollow tube slidably receiving a collet chuck. The chuck is operatively connected to a handle that is in turn pivotably mounted to the tube. Pivotal movement of the handle causes responsive movement of the collet chuck between an extended and a retracted position within the tube.

In the extended position, these serrations are separated from one another to enable loose positioning of the collet chuck over a lug stud. The handle is then pivoted to cause corresponding movement of the chuck to the retracted position. As the chuck is retracted into the tube, the gripping surfaces grip the shank between the thread cutting serrations. The tool may then be turned about the axis of the stud to renew or recondition the threads thereon.

Abstract: This invention is for a light-weight bridge floor and the like in which spaced parallel structural sections with top flanges and vertical webs are connected by cross braces threaded through openings punched through the webs of the structural sections at intervals along their lengths and at a level spaced below the top flanges of said sections and thereafter deformed in such manner that the cross braces cannot move relatively to the webs through which they pass and integrate the structure whereby loads are distributed from one structural section to the others and welding is unnecessary. Subsequently deck strips with skid-resistant surfaces are applied lengthwise over the flanges of the structural sections which are wider than the tops of the sections to such strips being wide enough to cover a single section, or of a width to cover a plurality of sections. The assembly may be made in situ on the bridge structure or preferably prefabricated in transportable panel sections.
