Abstract: 366,216. Plug-boards. LINKER, A., 47<II>, Heinrichstrasse, Hanover, Germany. Dec. 15, 1930, No. 37735. Convention date, Dec. 17, 1929. [Class 38 (v).] The three-pole supply conductors a, b, c are arranged horizontally one behind the other and interleaved with the three poles d, f, g of a consumer's circuit. For simultaneously connecting the supply bars to the consumer's bars, an insulating plug c is provided with conducting bands l, m, o, preferably resilient, of decreasing diameters which plug may be inserted in registering holes in the bars, or, as shown, between contacts h, i which are soldered, welded, or bolted to the bars a.. g. The contacts may be circular, as shown, or rectangular, triangular, or flat, and a number of sets of supply bars and consumer's bars may be arranged under an insulating plate. In another form, each bar is milled out to form a circular aperture p, and each contact l, m, o carries a sector q which, on rotating the plug after insertion, moves between its appropriate pair of bars a, d, &c. until an insulating stop s between that pair is engaged by a slot r in the sector, the slot r being shaped to provide a pressing action of the contacts l, m, o on the milled-out parts p. Further resilient contact pieces may be carried by the inner faces of the bars for engagement by the sectors which may also have resilient parts.

[Also in Divisions H1 and H4] In a telephone dial mechanism shown in Fig. 1, the plastics gear-wheel 5 fixed to the finger-plate spindle 3 drives the plastics gearwheels 15-14 of the intermediate drive and 18 of the brake drive, the free-standing shafts 12 and 13 carrying these two drives being eccentrically mounted in bushings 10 and 11 which can be rotated to adjust the distance between the shafts and so allow for the wide range of tolerances expected in the injection plastics moulding process for the gear-wheels. The centrifugal braking or governor mechanism carried on shaft 13 comprises two braking shoes 19 (Fig. 7) pivoted at 41, 42 which upon rotation bear at points 45, 46 against a plastics bushing 17 fixed in the shaft bushing 11. The pressure of the shoes against the bushing is adjusted by moving the spring 20 along the notches. Bimetallic impulse springs 26 are operated by impulse wheel 5 but are maintained closed during anti-clockwise wind-up by cam portion 23 of a cam 6 which slides over wheel 5 as its stop 28 engages the stud 25 of the contact springs. The springs remain closed during the initial return motion until stud 25 slides off the cam portion 23. A stop 25 on cam 6 engaging abutment 30 repositions the cam 6 on the wheel 5. The frictional coupling between the cam 6 and impulse wheel 5 is adjustable by turning a saddle spring 7 (Fig. 4) so that the free end engages a different position on the raised knurled part 33 of cam 6.

Apparatus for air cooling of filaments spun from molten polymer comprises a plenum chamber 1 communicating with a filament quenching chamber 2, said plenum chamber having mounted therein two coaxial perforated tubes 4, 5 adapted to be connected to an air supply (arrow A), the inner tube 5 being perforated throughout the length of its surface adjacent the quenching chamber 2. As shown, the tubes 4, 5 are suitably of the same length and the perforations in the outer tube 4 are provided only on the surface remote from the quenching chamber, and thus oppositely disposed to the perforations of the inner tube 5. The diameters of the holes 6 in the tubes 4 and 5 suitably increase in the direction of flow of air through the plenum chamber 1, which is separated from the quenching chamber 2 by meshes 3. The upper ends of tubes 4 and 5 are sealed by a cover 7, and the lower end face of tube 5 has a lip which abuts against the inner wall of tube 4 to ensure an intimate jointing of the two tubes. The amount of air fed to chamber 1 from air duct 8 is controlled by ball valve 9. This arrangement ensures a more uniform air flow, and enables longer perforated cylinders to be used. The apparatus is especially useful where an extended air quenching zone is desired, as in the production of high denier filaments.
