Title: Improvements in the manufacture of coiled coil filaments for electric incandescent lamps
IPC: H01K3/02
Filed: 1934-07-18
Abstract: In a method of manufacturing coiled coil filaments for electric incandescent lamps, tungsten wire, first wound on a primary mandrel, is then wound, together with its primary mandrel, on a continuous length of secondary mandrel, after which the secondary mandrel supporting the primary mandrel and the wire is drawn continuously through an oven which is maintained at a temperature so high that, if the wire were maintained at this temperature for one hour, it would re-crystallize completely, the duration of its stay in the oven, however, being so short that re-crystallization is not complete.  An oven temperature between 1500 and 1600 DEG  C. is generally suitable, and the duration of the heating between 5 and 60 seconds.  In an example, the body is drawn through a molybdenum tube containing a hydrogen-nitrogen atmosphere and heated to a temperature of 1550 DEG C. by passing a current through it, the length of the oven and rate of drawing the body therethrough being such that the duration of heating is 12 seconds.  The mandrels are then removed by solution in known manner.

Title: Automatic switching arrangements for reversing the direction of traffic over a telegraph line or cable
IPC: H04L5/18
Filed: 1926-08-26
Abstract: 281,363. Marks, E. C. R., (Western Union Telegraph Co.). Aug. 26, 1926. Type-printing telegraphs; distributer systems; synchronous movements.-In a system provided with automatic switching arrangements for reversing the direction of traffic over the line at pre-determined intervals as described in Specification 228,828, the reversing switches are actuated directly by cams without the intervention of relays. The sets of brushes b, b<1> - - b' of the distributors RD at the two stations A and B are each driven by a motor 10, one motor being arranged to run slightly faster than the other, and synchronism is maintained by the energization from a correcter relay CR at the receiving station, over the brush b<3> and the distributor rings 4, 4<1>, of a magnet M actuating a device S for shifting the brushes backwards or forwards. The reversing switches at each station are actuated by cams on a shaft 12<a> through a friction clutch 26 and an escapement from an electromotor 12, this motor and the escapement being controlled by timing switches, 15 - - 17 closed at pre-determined intervals by cams 18 - - 20 driven through reduction gearing from the motor 10 at speeds of, e.g. 4, 1, and 1/12th revolutions per minute respectively. Simultaneous closure of the switches 16, 17 completes a circuit for the motor 12 from + battery 23 to - battery 24, but rotation of the shaft 12<a> is prevented by one or two of the prongs of the pawl 27 locking the escapement wheel. The subsequent closure of the switch 15 completes a circuit for the escapement magnet 38 from + battery 30 through distributor ring 1, brush b, lower half of ring 1<1>, inner contact of switches 16, 17, and switch 15 to - battery 24. The pawl 27 is thereupon moved by the magnet 38 to disengage the escapement wheel and allow it to rotate until the other prong of the pawl engages the next tooth. This slight rotation of the shaft 12<a> enables its cam c<5> to close at contacts 40 a hold-on circuit for the magnet 38 in shunt to the switches 15 - - 17. The magnet 38 is thereupon energized during half of each revolution of the distributer to advance the escapement wheel one tooth, and the shaft 12<a> is thus rotated until, after half a, revolution, the cam c<5> opens the contacts 40. During this rotation (1) the cam c<1> disconnects the cable C from the ring 3, brush b<2>, ring 3<1>, and transmitter T and connects it to the receiving relay PR and correcting relay CR, or vice versa, (2) the cam c<2> correspondingly closes or opens connection of the tongue of relay PR with the ring 5, brush b<4>, ring 5<1>, and printer magnets PM, and the connection of the tongue of relay CR with the ring 4, (3) the cam c<3> correspondingly opens or closes the circuit of the actuating magnet tm of the transmitter T, (4) the cam c' closes intermittently a circuit through the magnet M to maintain the distributors in synchronism during the change-over.

Title: Improvements in or relating to arrangements in straight bar knitting machines for controlling the movement of thread guides
IPC: D04B15/64
Filed: 1964-05-25
Abstract: Towards each end of the carrier traverse, the friction box (2) Figs. 3 and 4, not shown, of a straight-bar machine engages a lever (9) which bears against a roller (10) mounted to revolve with a shaft (11).  The roller (10) moves in the arc of a circle about the shaft (11) and its rate of movement is restricted to cause the retardation of the carrier movement by the shaft (11) being prevented from rotating at a rate faster than that of a continuously rotating shaft (16).  This is achieved by a roller clutch (13) which is interposed between the shaft (11) and the gearing (14, 15) coupled to the shaft (16).  In the event of the lever (9) moving at a rate whereby the roller (10) and shaft (11) are rotated at a speed which exceeds that of shaft (16), the shaft (11) becomes coupled by the clutch (13) to the shaft (16) and immediately the rate of movement is restricted. The shaft (16) is continuously rotated in one direction but where the width of knitting is varied the rate of rotation is varied with the width and is achieved by coupling the shaft to the tie bar and by providing a pair of level gears which are alternately coupled with the shaft 16 to ensure that it is driven in one direction only.
