Abstract: 1358497 Endless conveyers DEBAG DEUTSCHE BACKOFENBAU GmbH 17 July 1972 [28 July 1971] 33366/72 Heading B8A Pieces of dough 16 are transferred between process units 14, 15 by an endless belt 12, the pieces then being deposited by the belt into transverse tipping troughs 17 of an endless chain conveyer 13 which discharges the pieces into a carrier 21 removable by an operator. The troughs 17, during their travel along a lower run 27 and a vertical run at the left of the conveyer, depend freely from the chains. The troughs have cams 36 which engage discs 38 coaxial with chain sprockets 28, the troughs thus being disposed radially of the discs. Rollers 34 on the cams 36 are thus engageable with an ' inclined rail 39 and the troughs take up an attitude to receive the pieces of dough from the belt 12. Along the upper run 19 of the conveyer 13 the rollers 34 engage a vertically movable control rail 35 which, until the number of troughs 17 coincides with the number of receptacles 25 in the carrier 21, is maintained raised, and the troughs are not discharged. When the feeding trough is detected by feelers 23 the rail 35 is lowered and the troughs discharge into the correct receptacles 25. The rail 35 is activated by eccentrics 45 driven by a chain 47. The conveyer 13 is driven step-by-step, in synchronism with the drive for the belt 12. In a modification, Fig. 10, a carrier 54 transverse to the conveyer 13 replaces the longitudinal carrier 21. The feelers 22 are correspondingly adjusted along the conveyer 13.

Abstract: 431,549. Grinding &c. screw threads. LINDNER, H., 9, Lubarser Strasse, Wittenau, Berlin. Nov. 23, 1934, No. 33742. Convention date, Dec. 5, 1933. Addition to 414,865. [Class 60] In machine tools for grinding &c. screw threads provided with means according to the parent Specification for compensating for backlash in the gearing driving the lead screw, the axial compensating movement of the leadscrew 27 is effected by a co-operating curved or cam surface 51 and projection 52 carried respectively by a stationary sleeve or bush 49 and a partially-rotatable and slidable bush 48 forming the bearing of the lead-screw, or vice versa. On reversal of the machine the bush 48 is rotated by the friction between it and the end of the lead-screw shaft, the amount of the rotation being determined by the movement of a lug 35 on the bush between a fixed stop 32<111> and an adjustable stop 36. This rotation causes relative movement between the cam 51 and projection 52, and hence a longitudinal movement of the bearing bush 48 and the leadscrew 27, which, as described in the abridgment of the parent Specification, effects the required compensation. The friction between the leadscrew shaft and the bush 48 may, to ensure rotation of the latter, be increased by brake members 55 carried by the bush and bearing on a collar 27<1> on the shaft.
