This data processing system for a pattern generator receives data specifying each quadrilateral element in a pattern to be generated by laser scanning or other technique. The scanning is accomplished by swaths. In the preprocessor, separate vectors are produced for the portion of each quadrilateral edge in each swath. A real time processor, including a "pipeline" or cascaded set of beam processors...

A holder for a textile-bobbin tube open on both sides has the form of a crossmember, on the top side of which the bobbin tube rests. The crossmember has, at the front end, a nose which is loaded against the front end face of the bobbin tube at one point by an additional force by means of a pressing device loaded by a tension spring. The functions of carrying and holding the bobbin tube are in this...

Odontologic compositions suited for use as denture adhesives, the compositions containing a major amount of gum base and a quantity of a hydrophilic polymer to modify the adhesive properties of the gum base together with processes for producing such compositions.

A mechanism for raising and lowering a seat, especially designed for handicapped persons, comprises two supporting arms (A', B') which are both at one of their ends coupled to the seat (E), at the front and rear edge thereof, respectively. At their other end, the supporting arms (A', B') cooperate with a fixed point (1', 2') each. At least one of the supporting arms is coupled to a driving member ...

A pulper to convert bulky, solid wastes from food service establishments into a uniform, moist pulp. The material is pulverized in a first section and transferred as a slurry to a second section where the slurry is dewatered by an auger. To prevent clogging of the auger, a portion of the liquor extracted from the pulp is introduced as a jet stream into the upstream end of the auger to create turbu...

A first reaction mixture, prepared from (a) isocyanates with isocyanate contents of from 5 to 50% and (b) compounds with molecular weights of from 32 to 10,000 which contain at least two isocyanate-reactive hydrogen atoms, in an equivalent ratio of component "a" to component "b" of 0.8:1 to 5:1, from 0.1 to 20% of a blowing agent and, optionally, other known additives, is introduced into the rigid...

The actuator comprises a piston (34) which has a stepped portion (36) formed with an annular groove (38) at its end projecting out of a cylinder (16). An annular protective sheet (50) is slipped on the stepped portion (36) and it comprises at its radially inner edge (52) inwardly projecting, resilient tongues (54) which are arrested in the annular groove (38). An annular elastic sleeve (46) is arr...

Hollow metal microspheres are made from film forming metal compositions and are used to make superior high strength light weight structures, improved insulating materials and insulating systems, or the microspheres can be used as filler materials in plastics, in plastic foam compositions, in rubber and rubber compositions and in metal compositions. A thin metal coating can be deposited on the inne...

A glassy material spraying and painting method comprising directly spraying a powdered glassy material onto a surface of an object to be painted to form a glassy coat on the surface. It is also possible to perform an undercoat on the surface before the glassy material is sprayed thereon.

A plastic part composed primarily of a polyamide resin such as 6-nylon blended with another mutually-soluble resin, the part capable of withstanding environmental stress cracking caused by deicing salts containing calcium chloride. The resin blend has a saturation water absorbability of less than 6.0%. Under use conditions, such plastic parts, typically in the form of radiator parts, water separat...
