Title: Improvements in and relating to electric valve circuits
IPC: H02M7/44

Abstract: 419,757. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of SCHMIDT, A. ; 1147, Parkwood Boulevard, Schenectady, New York, U.S.A.) May 29, 1933, No. 15483. Convention date, May 27, 1932. [Class 38 (ii).] In an electric power conversion apparatus the positive ion current in the valves builds up quickly in a self-saturating reactor included in the grid circuit, after each valve has become non- conducting. Energy is transmitted from the D.C. system 10 to the single phase A.C. system 11 by an arrangement including a transformer 12, electric discharge devices 15, 16 and a commutating capacitor 18. The grids of the discharge devices are influenced by potential of peaked wave form obtained from the self-saturating transformer 19 and A.C. source 20. Included in the grid circuit of valve 15 for example is a biassing circuit comprising a condenser 23, a high resistance 24, a self-saturating reactor 22 and a resister 21, and a rectifier 25 is used to byepass the reactor 22. The reactor has a relatively high reactance for magnetomotive forces less than a predetermined value and a relatively low reactance for higher values of magnetomotive force. When the grid is made positive by the positive peak of the control potential, the condenser is so charged that when this control potential has died away and the valve is conducting, the grid is negatively charged. Positive ion current from the valve then flows to the negative grid and through the reactor 22 in a reverse direction to the normal grid current. In order that the negative charge of the condenser shall not be destroyed, the self-saturating reactor 22 is so dimensioned that it becomes saturated just before the valve becomes nonconducting and then allows the positive ion current to build up quickly. The rectifier 25 byepasses the normal grid current from the reactor 22, and the rectifier 26 byepasses the negative half cycles of the grid control potential as described in Specification 415,546.

Sewing-machines; braids and the like, attaching; trimming or cutting.-In a sewing-machine particularly suitable for attaching strips or stays to shoe-uppers, a movable strip guide is provided by the movement of which a cutting member is brought into operation to sever the strip. In the multiple needle chain stitch machine shown, a guide 16 of angular form is provided pivoted on a plate 19 and formed with a channel 21 having a tension finger 21'. The channel 21 is covered by a plate 22 and an L-shaped member 24 which forms a ledger-blade of the cutting mechanism. An arm 25 depending from the strip-guide is connected to a rod 27 transverse to the machine and stressed by a spring so as to hold the guide normally in the upper position. The end of the rod 27 is engaged by the bevelled end of a rod 33 pivoted to a link 34 mounted on one arm of a lever 36 the other arm 38 of which is under manual control through a rod 39, lifting of the rod effecting the depression of the guide. The forked end 34<1> of the link 34 engages a bell-crank 41 the movement of which lifts the presser-foot. A second cutting blade 46 having a forked end is mounted on a spring-stressed pivot 50 by which it is held up to the edge of the ledger-blade 24. The end of the blade 46 engages a fixed stud to hold the blade in fixed position or engages a pin 56 connected to a lever 58 having a pin 60 extending into the sleeve of a strap 61 embracing an eccentric on the main-shaft. In the latter case the lower blade is continually reciprocated but is only effective to cut the strip when the guide is depressed. An extension 63 of the feed-dog carrier carries a small rocker 65 supporting a strip-feeding member 66 which projects through a slot in the guide and engages the underside of the strip. Means are provided for withdrawing the member 66 from contact with the strip comprising a wedge 73 adapted to be pressed into engagement with the lower arm of the rocker 65 against the action of a spring by a bent lever 74 having a lateral face 75 which is pressed against a member 69 carrying the wedge.
