Title: Automatic starting arrangement for synchronous motors
IPC: H02P1/46
Filed: 1944-03-30
Abstract: 595,124. Control of motors. GERMANY, L. W., and PYE, Ltd. March 30, 1944, No. 5864. [Class 38(iii)] [Also in Group XXXV] With auxiliary starting motor. - The operation of a starting motor M, which is coupled through free wheel or like mechanism to a synchronous motor P, which may be a phonic motor, is controlled by a part of the alternating current motor input through a rectifier which is biassed so that initially the rectified output causes the motor M to start and, when the synchronous motor reaches its operating speed, the bias on the rectifier is such that the starting motor is stopped. A relay Z, the contacts Z1 of which complete the circuit to the motor M, is connected in the cathode lead of the rectifying valve V. A condenser C is normally connected to the grid of the valve and when a switch S is operated by a cam A the condenser is disconnected from the grid, allowing the grid to become positive and short - circuiting the condenser. When the switch is again operated, the grid becomes negative and the valve is cut off until the condenser is re-charged. When the speed of the motor is such that the condenser does not become sufficiently charged before it is again short-circuited the starting motor is stopped. A smoothing circuit is connected across the relay coil to prevent chatter and to prevent release of the relay for a short period to allow the phonic motor to reach a speed slightly higher than its running speed. A magnetic clutch may be used to couple the starting motor and the synchronous motor. Specifications 577,795 and 577,796, [both in Group XL], are referred to,

Title: Improvements in method of and mechanism for knotting strands together
IPC: B65H69/04
Filed: 1930-02-25
Abstract: 348,251. Knot-tying machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Warp Twisting-In Machine Co. ; 164, Tillary Street, Brooklyn, New York, U.S.A.) Feb. 25, 1930, No. 6282. [Class 112.] Warp strands for such fabric as "Georgette" are joined by weaver's knots to avoid the unsatisfactory connection resulting from mere "twisting." The two warps, old and new, are suspended from clamps 1, Fig. 25, under tension and extend between the limbs of the fork 2 to the supply beams. They are released in pairs and fed forward in the usual manner and delivered in pairs to the guides 5, 6 of the fork. The fork is reciprocated by the cam 7. While engaged in the guides 5, 6, the strands are crossed, Fig. 1, by a spiral cam 11 rotating with shaft 9. The cam engages the strand a and moves it into the detainer 5a at the end of the guide 5. Further rotation of the cam 11 clears the strand a from over the guide 6 transferring it from guide 5 to guide 6, Fig. 2, and wrapping the strand b round the strand a at pivots x and y, Fig. 3, by the fork 2, which is then advanced by the cam 7 to carry the crossed strands to the knotting mechanism 12 secured to the shaft 8, Fig. 13. The strands are separated by the point 15 of a hook 16 carried by a lever 17, operated from the cam 14. The hook then shifts to the left and draws strand b with it, crossing the strands again to form a loop b<1>, Fig. 3. The knotting bill 20 then enters the loop b<1>, Fig. 13a, and remains stationary, while a lever 26 moving universally on a stud 27 and operated by links 30, 31 engaging a cam track in the eccentric 14, forms a second loop, in the strand a, Fig. 4. The knotting bill then engages the strand a, cuts it, and pulls it across the strand b to form the knot, Fig. 5. The knotting bill is carried by the lever 18 operated by a cam-track on the eccentric 14 and operating the hook 16 by the lever 17. A lever 24 pivoted at 25 on the bill, engages a second cam-track t open and close the cutting jaws 24a, 18a of the bill, Fig. 17.

Abstract: 964,604. Laminates and laminating. FMC CORPORATION. Feb. 19, 1962, No. 6385/62. Heading B5N. Open-mesh woven rayon fabric. or similar unwoven rayon fabric made by adhesively securing the warps and wefts at their crossing points, is laminated between two webs of paper coated with aqueous adhesive such as polyvinyl alcohol, animal glue, carboxymethyl cellulose or rubber latex, under conditions in which the normal extensibility of the fabric (for example 18%) is reduced to that of the paper (for example 4%) by pre-stretching the fabric by the amount of its excess extensibility and effecting the bonding, and drying the laminate, in the stretched condition of the fabric. As shown, a web of open-mesh rayon fabric 10 is supplied to a pair of rolls at 14 from a supply roll, the speed of which is adjusted in relation to that of the rolls 14 to effect the desired longitudinal extension of the fabric, lateral extension thereof to the same extent being effected by gripping each edge between a pair of rotatable nip-discs such as 19 set at a slight angle to one another. Upper and lower paper webs 11, 12, which are untensioned, are sprayed on their inner surfaces with aqueous adhesive and fed between the rolls 14 and the laminate so formed is passed around heated pressure rolls 22 and delivered at 23.
