Abstract: 517,728. Clocks. LOEFFLER, F. June 25, 1938, No. 18910. Convention date, June 25, 1937. [Class 139] Winding-apparatus, electric.-An electric clock of the type driven by a spring intermittently wound by electromagnetic means is constructed so,as to allow easy separation of the electrical and mechanical parts. Six U-shaped pole pieces 6 and the coacting ring coil 7 are embedded in an artificial resin stator frame 1 and actuate an oscillating armature 2 which carries inclined prongs 4 to drive unidirectionally a wheel 39 geared to the hands 36 and 38. The armature 2 has six radial pieces coacting with the six poles 6 and is fixed to a sleeve 12 which oscillates in a fixed sleeve 11 and has attached to its upper end a member 13 of non-magnetic, conductive material. When coil 7 is energized. by the closure of contacts 21, 22 it rotates the armature 2, and member 13 rotates clockwise, Fig. 10, from stop 24 to stop 25 and stresses the driving spring 3 by the following means. A lug 16, 16a on member 13 engages the end of a lever 15 to which is attached one end 23 of the spring 3. The other end of the latter is hooked over an S-piece 17 which pivots on a fixed bolt 18 and forms part of the electric contact spring 14 bearing the contact 21. Parts 13 and 15 also control the contacts, of which 22 is on the member 13. - The lever 15 is also held by a lug 22a, 22b on the member 13 and passes through a slot in the arcuate end of spring 14: A cam nose 27, 29 on lever 15 coacts with a face 28 on spring 14. As the parts 13, 15 are rocked clockwise by the armature. 2 the nose 27- passes to the right under the face 28 so that the latter rides suddenly up the face 29 to lift the spring 14 and separate the contacts 21, 22. The stressed spring then drives the hands, under control of an escapement, until the arm of member 13 returns counter clockwise to the stop 24, at which point the contacts are again closed. Hand-setting apparatus.-A. setting knob 50 is attached to a shaft 49, within the sleeve 12, which has a cranked end 51 coacting with an aperture 53 in a disc 52 attached to the minute hand arbor 35.

Title: Improvements in or relating to preparation of pure metallic carbides
IPC: C01B31/30
Filed: 1948-07-14
Abstract: In a method of purifying metallic carbides in which the regulus contains graphitic carbon, lumps of the regulus are crushed with a maximum of impact breaking and a minimum of attrition grinding to a size which will release a substantial portion of the graphite, then subjected to attrition grinding to a size which liberates all the graphite and finally the ground carbides are subjected to froth flotation to separate the graphite.  The crushed particles, particularly when the graphite content is above 8 per cent may be also subjected to a froth flotation prior to attrition grinding.  The lumps may be crushed in a jaw crusher, then to 10-65 mesh size by stage crushing or in an air swept ball mill or ring roll crusher so that the amount of fines is a minimum.  The attrition grinding may be in a wet, or dry, ball mill to a size from -150 ti -325 mesh.  The froth flotation may be carried out at 10-50 per cent solids using pine oil as the frother.  The carbides form the sink portion and may be acid bleached, filtered, dried and crushed to give a product of -325 mesh.  The carbides which may be treated are those of V, Ti, W, Zr, Nb, Ta, Cr, Mo and B.  U.S.A. Specification 2,310,964 is referred to.

Title: Thread winding control mechanism for sewing machines
IPC: D05B59/00
Filed: 1964-05-11
Abstract: 994,629. Sewing machines. SINGER CO. May 11,1964 [May 14,1963],No.19504/64. Heading D1G. In a lock stitch sewing machine in which a bobbin, journalled in a rotary looptaker, may be rotated in order to be wound in situ by needle thread during normal operation of the needle and looptaker, and comprising means for sensing a predetermined amount of thread on the bobbin, the bobbin-rotating means is driven by an electric motor having a drooping load-speed characteristic, and means responsive to the thread-sensing means is operative for increasing the load on the bobbin-actuating means. A looptaker body 30 is carried by a hollow shaft 18 driven by a gear 21, rigid therewith, from the machine bed shaft. A stationary bobbin case 32, journalling the looptaker, journals a bobbin 34. A bobbin-actuating member 50 has a vertical rim 55<SP>1</SP> and is rigid with a shaft 51 journalled in shaft 18. A leaf spring 62, carried by a lever 60, embraces the lower end of shaft 51, whereby, when lever 60 is actuated to raise shaft 51, a pin 58, carried by shaft 51, enters a recess 59 in gear 21, and a pin 53 on member 50 enters a recess 54 in the bobbin. An arm 100, pivoted at 99 on the bobbin case, has an end 102 adapted to be engaged by the thread wound on the bobbin. When the latter is fully wound, a bevelled surface 103 on arm 100 engages rim 55 to depress shaft 51, against the bias of spring 62, to increas the load on the driving motor which is of the series commutator type having a drooping load-speed characteristic. The motor speed thereby falls to provide a signal to the operator. If the signal is disregarded, the increasing load serves to stall the motor.
