In constructing assembled batteries by electrically connecting through a connecting bar the terminals of neighboring single cells by means of metallic parts of the terminals, by directly covering both sides of the connecting bar with the exception of the electrical connection with an insulating protecting layer of either natural rubber, synthetic rubber, or synthetic resin, and by directly or indirectly insulating and protecting the surface of the metallic parts for electrical connection, it was...

A diffuser for association with a centrifugal compressor includes a circumferentially disposed array of like, individual diffuser vanes each having integrally formed opposed flange pairs thereon joined by a bridge segment having a continually increasing depth from an inlet end of each of the vanes to the outlet end thereof. Adjacent ones of the vanes have their flange pairs juxtaposed to form a three-dimensional air flow passage between each of the vanes and wherein each vane has a spiral formed...

A camshaft having a steel shaft and cam pieces made from a sintering iron-base alloy material and fixed to the shaft by sintering. Prior to sintering, the green or pre-sintered cam piece is fitted on the shaft and positioned by a steel positioning pin, which is inserted both into a pin-receiving hole in the shaft and into a pin-receiving groove on the side surface of the cam piece. The positioning pin contains carbon less than the steel shaft. This results in that the carbon diffusion initiates ...

An assembled commutator for use in a fractional horsepower electric motor comprises a base moulded from thermoplastics and a commutator segment mounted on the base. The segment has a tang for electrical connection to an armature coil, the tang comprising a first radially extending portion and second portion connected to the first portion along a fold line. Wire of the coil is passed may be welded or forged to the tang by pressing together the first and second portions, and heating them electrica...

This invention relates to caskets. It is for caskets that can be fabricated in such a manner that they are adaptable to assembly at point of use. In the manufacture of caskets, the cost of transportation between assembly point and the mortician has continued to grow out of proportion to the cost of the casket. The unassembled or knocked down parts shipped directly to the mortician would reduce freight charges and storage space requirements. By assembly at the point of use it might well lead to l...

A process for producing an assembled crankshaft, transmission shaft or camshaft, in the case of which expansion of the inserted sleeves takes place for the purpose of producing a force-locking connection between slid-on drive elements or bearing sleeves and tubular members, and where bored plugs are inserted, so as to be pressure-agent-proof, into the open ends of a sleeve with the cavity formed by the sleeve and the inserted plugs being pressurized by a pressure agent up to the point of permane...

The invention relates to an assembled driveshaft and a process for production thereof in the case of which several tubular pieces and/or sleeves and a driving element to be attached thereon are inserted into each other and where, for forming the stepped hollow shaft and for fixing the driving element, the inner tubular portion of a region of overlap produced in the process, at least within the driving element, is expanded from the inside relative to the outer tubular portion and the driving elem...

An assembled commutator has a segment support portion and a housing portion. The housing portion has housing members formed with axially extending "T"-shaped recesses and transversely extending slots for receiving armature leads. Insulation displacing terminals are inserted in the "T"-shaped recesses and formed with slots which cooperate with the transversely extending slots to grip and contact the armature leads. The terminals are held in place by commutator segments which are formed separately...

The present invention discloses an assembled lampshade which includes two sector shades, a plurality of spiral connectors connected to the edges of the sector shades which are secured to each other in a face-to-face position, and a plurality of supporting members engaged with the sector shades and the spiral connectors to construct a firmly assembled lampshade. During transportation and storage of this lampshade, all of the supporting members can be disassembled and the sector shades with the sp...

An assembled commutator has an insulating commutator body having a cylindrical outer surface, radially extending axial support means and an axial extension on the opposite side of the axial support means to the cylindrical outer surface. Three commutator segments each have an arcuate brush-contacting portion seated on the cylindrical outer surface of the commutator body, an axial terminal stem extending through a passage formed in the axial support means, and a radial terminal stem seated in one...
