Abstract: 1,052,579. Ignition systems. FORD MOTOR CO. Ltd. July 28, 1965 [Aug. 3, 1964], No. 32211/65. Heading F1B. In a coil ignition system comprising an electronic switch (transistor 17) which controls the flow of current in the primary winding 15 of the coil and a resistor 29 which limits the maximum current in the primary circuit, a by-pass connection around the resistor is established when both the starter motor is operated and the voltage of the source of electrical energy is below a predetermined value. As shown operation of the starter motor connects a relay winding 108 to the source and also establishes the by-pass connection. A set of break contacts 107 of the relay is actuated in the by-pass connection and the energization of the relay is sufficient to operate the break contacts when the voltage is above the predetermined value but is insufficient to operate the break contacts when the voltage is below the predetermined value. A negative temperature coefficient resistor 110 may be connected in series with the relay winding so that at lower temperatures a higher current flows through the relay winding thus lowering the predetermined value of voltage. The capacitor 114 connected between the lead 38 and ground is a protective device for the transistor 17. The ignition timing is retarded at starting.

IPC: D04B9/20
Abstract: 1,053,128. Knitting-machines. SOLIS SOC. A RESPONSABILITA LIMITATA. Aug. 10, 1964 [Aug. 13, 1963; May 27, 1964], No. 32438/64. Heading D1C. A picker is provided in a circular machine and is adapted to either raise the needles to an inoperative position or to lower them to an operative position. For this purpose the picker 28 is aligned with the top or bottom edges of a slot 11 in a plate 10, the slot having a V shaped lower edge and an inverted V shaped upper edge such that when the picker is accommodated on either the upper or lower edge it is compelled to swing upwardly or downwardly according to the dictates of the respective edge of the slot as it is deflected sideways by the butt of the leading needle. In a two feed machine a picker is positioned on either side of a central stitch cam 12, Fig. 9 not shown, a further stitch cam 13, 14 being positioned on either side of the pickers and capable of being pivoted so that in one direction of movement during narrowing the leading pivoted cam 14 is lowered and lifts the needle butts to sufficient height so that the leading needle engages the picker 28 and is raised to an inoperative position clear of the central stitch cam 12. This action occurs when the picker engages the lower edge of the slot 11. At the next feeder the second picker engages the then leading needle and raises it above the pivoted stitch cam 13 whereupon the succeeding needles are lowered and knit under the cam 13. In the reverse direction of knitting the cam 13 is lowered and the cam 14 raised with the resultant effect that narrowing occurs during reciprocating knitting by one needle at each feed in each direction of knitting. The pickers in a two feed machine may be mounted on a common plate to raise or lower them simultaneously into one or other of the positions whereby narrowing or widening can be performed for when the pickers are raised to engage the upper edge of their slots widening will occur. In addition a third picker may be provided at a position diametrically opposite the central stitch cam 12 and operated during narrowing to lift a further needle into an inoperative position. During widening however the third picker lowers three needles whilst the other two raise one each so that a net gain of one needle is made each reciprocating course. The picks are resiliently mounted to return to their operative position after actuation.

A process for electric resistance butt welding of wires, rods or chain links comprises bringing ends to be welded into contact, switching on welding current, switching off the current and upsetting the heated ends, the ends being pressed together under limited pressure during passage of the current, but more positively during upsetting. Tools 11 for pressing the ends together are held in holders 12 mounted on a pair of lever arms pivoted at 14. The lower ends 15 of the lever arms are connected, through toggle linkages 16 to a plate 17, the movement of which in a vertical plane is derived from a cam-andfollower drive (Fig. 2, not shown); movement of plate 17 upwards causes the tools 11 to move together. The linkages 16 (Fig. 3) each comprise two parts 30, 33 telescoped together, but urged apart by a spring 43. The movement towards each other of the parts 30, 33 is limited by a pin 34 in a slot 35, or by abutment of a surface 31 with a surface 42. The degree of movement of the parts is adjustable through nuts 30A, 38. Alternatively, the resilient connection between the plate 17 and the tools 11 can be positioned elsewhere. During the passage of welding current the cam follower and hence plate 17 moves to a limited degree, whereby the force transmitted to the tools 11 is limited by the spring 43 in each linkage 16. During upsetting, however, the movement of the plate 17 is greater so that either the parts 30, 33 abut via pin 34 and slot 35, or the surfaces 31, 42 abut and the tools 11 are moved together positively.

Abstract: 1,250,191. Phosphoric acid; gypsum. FISONS Ltd. 17 June, 1969 [4 July, 1968], No. 31982/68. Heading C1A.  A prior process described in Specification 1,135,951 for the production of phosphoric acid and calcium sulphate semihydrate in three stages is modified by the addition of a fourth stage in which the washed CaSO 4 .¢H 2 O is recrystallized to form gypsum in an aqueous solution at a temperature of 30-70‹ C., the solution containing 2À5-10% by weight of H 2 SO 4  and having an H 2 SO 4 : P 2 O 5  ratio in the range 0À6- 3À4 : 1 and subsequently separating gypsum crystals from the aqueous solution by filtration, part of the filtrate resulting from the filtration of the gypsum crystals being used as at least part of the third-stage wash for the CaSO 4 .¢H 2 O.
