Abstract: Nickel-chromium alloys, particularly for casting, contain  .Cr.10-35% .Nb.2-12% .Mo.4-16% .C.\sO 0,1% .Si.\sO 0,5% .Mn.\sO 0,5% .W.0-12% .Co.0-40% .Fe.0- 5% .B.0- 0,1% .Zr.0- 0,1% (0-1% when W present) .Be.0- 1% .Ni.\sP25% The alloys are hardened by the presence of niobide phases and carbon should therefore be kept low.  Best properties are developed by solution treatment in the range 1050-1125 DEG C., followed by ageing in the range 700-900 DEG C.  Improved room temperature properties are obtained when the ageing temperature is below 750 DEG C.  The niobium content of the alloy includes the small amount of tantalum often associated with commercially available niobium.

Title: Electrically-controlled stop-motion system
IPC: D05B69/22
Filed: 1949-10-08
Abstract: 659,558. Control of A.C. motors. FAIRWEATHER, W. C. (Singer Manufacturing Co.). Oct. 8, 1949, No. 25899. [Class 38(iii)] [Also in Group VII] Relates to the control of an induction motor 22, 23, which drives the main-shaft 5 of a group-stitch sewing machine (see Group VII). The shaft 5 carries a driving pulley 12, a stop-cam 11, and a timing cam 18 which actuates a work-holder to distribute the stitches in accordance with a chosen pattern. The machine is started by pulling a chain 19 downwardly to move a pivoted stop-lever 9 out of engagement with the stop-cam, the stop-lever being held in the disengaged position by means of a latch 13 against the influence of a spring 16. Contacts 26 of a switch S1 are closed by a depending portion 25 of the lever 9 when the lever is in its operative position. The latch 13 must engage the lever 9 before contacts 34 of switch S3 are closed, whereupon a closing circuit for a contactor 41 is made through contacts 34, 26, 31, 32 and 40 to energize the high-speed winding 22 of the motor. The cam 18 is driven so that, towards the end of the stitching-cycle, a follower 29 drops into a notched cam-portion 28, opens contacts 31, 32 of switch S2, and closes contacts 30, 31. The contactor 41 opens to de-energize the motor-winding 22 and a closing circuit for contactor 35 is made through contacts 34, 26, 31 and 30 to energize the low-speed motor winding 23. Contacts 34 are shortcircuited by contacts 39 and contacts 30, 31 by contact 37 so that the maintenance of the contactor 35 is now solely dependent upon the switch S1. Further movement of the cam 18 causes lug 17 to engage latch 13 and release lever 9, which finally rides into the "stop" position, the switch S1 opening to de-energize the motor. The driving of the machine substantially to the positive stop enables trimming or like operations to be performed at the end of the stitching cycle. In a modification, Fig. 5 (not shown), the switch S1 is dispensed with and switch S3 controls the disconnection of the motor at the end of the stitching cycle. Specification 648,124 is referred to.
