Title: Improvements in or relating to the manufacture of highly polymeric compounds
IPC: C08G73/00
Filed: 1939-01-23
Abstract: Highly polymeric compounds are prepared by heating an organic compound containing, in each molecule, a hydroxy radical and a radical having the formula <FORM:0560785/IV/1> , where R and R1 is each a hydrogen atom or a hydrocarbon radical, or by heating a mixture of a dihydroxy organic compound and an organic compound containing in each molecule two of said radicals having the formula <FORM:0560785/IV/2> , heating being continued until a polymer of high molecular weight having film-forming properties has been produced. Thus, a hydroxy-urea may be heated alone, or a di-urea may be heated with a glycol.  The compounds employed are preferably aliphatic compounds in which the reactive radicals are linked by methylene groups.  Other polymerforming reagents, e.g. dicarboxylic acids, diamines, or both, may be present with the starting materials. Suitable reaction temperatures are 150 DEG -250 DEG  C. or even higher, and the reaction may be carried out under atmospheric or sub-atmospheric pressures.  The products may be shaped into filaments, foils, films and the like.  Examples are given of the preparation of polymers from hexamethylene di-urea and hexamethylene glycol.

Title: Methods of continuously cutting bevel wheels
IPC: B23F9/10
Filed: 1957-05-07
Abstract: 865,710. Gear-cutting. HARBECK, M., [trading as HEIDENREICH & HARBECK]. May 7, 1957 [May 7, 1956], No. 14506/57. Class 83 (3). A method of continuously cutting teeth in a workpiece to produce a gear-wheel having teeth which are arcuate in their length-direction, which method comprises disposing the cutting- edges of a tool on a circle K 2  representing the curved teeth of an imaginary matching-wheel which would mesh with the gear to be cut, effecting a generating movement between the tool and the work by moving the tool in a circle which is concentric with the work, and rolling the circle about a circle K 0  on the work while the latter is imagined to be stationary so that the cutting-edges describe a cycloidal path relatively to the work, rotating the work around its axis to convert the cycloidal movement of the cutting-edges into an arcuate movement, and selecting the position and nature of the movement of the tool-circle relatively to the circle on the work about which it rolls, so that the toolcircle is the matching-circle of the cutting-circle and during rolling, generates the same cycloid as the cutting-circle. The tool has the same number of cutters as the theoretical face-gear has teeth. The tooth profile is octoid, straight or curved, and the gear and pinion may have offset axes. In producing the gear G and pinion P, Fig. 30, the cradle-axis A 1  is coincident with the gear-axis, and the cradle-axis A 2  is at rightangles to the pinion-axis. Accurate arcs are cut on the teeth only when the face-gear has an integral number of teeth. If it has not, the nearest whole number is chosen for the number of teeth on the cutter. Approximately arcuate teeth can be ground exactly circular after heattreatment. To produce a pair of gears with reduced contact, concave flanks of greater radius than that of the convex-flanks are generated by a cutter having teeth I, II, Fig. 41. The edges of the tool I lie on the circle K 2  to produce matching circles of radius r 1 ; but the edge of the tool II which produces the concave flank, lies on a smaller circle K 2 <SP>1</SP>, to produce a matching circle K 1 <SP>1</SP> of radius r 1 <SP>1</SP>, and the convex cutting-edge produces a circle K 1 <SP>11</SP> of smaller radius r 1 <SP>11</SP>. German Specification 932,989 is referred to.
