Abstract: The invention comprises compounds of the general formula: <FORM:0952698/C2/1> wherein R, R1, R2 and R3 are the same or different and are each of C1-C4 alkyl radical. They can be prepared by reacting a compound of the formula <FORM:0952698/C2/2> wherein X is a mercapto radical (SH) or a halogen atom with a compound of the formula: <FORM:0952698/C2/3> or with a compound of the formula: <FORM:0952698/C2/4> the compound of formula II being used when X is a mercapto radical and the compound of formula I being used when X is a halogen atom. In either type of reaction it is desirable to employ an organic solvent, e.g. a liquid aromatic hydrocarbon. In the first type of reaction (in which X is a mercapto radical) the reaction is suitably carried out at slightly elevated temperature and in the presence of a catalyst such as a tertiary amine, e.g. pyridine or trimethylamine, and a polymerization inhibitor, e.g. hydroquinone or it alkylated derivatives.  The second type of reaction (in which X is halogen) is also preferably carried out in the presence of a basic condensing agent e.g. the above specified tertiary amines. Examples are given for the production of compounds in which R, R2 and R3 in the formula are each ethyl, and R1 is ethyl and methyl respectively. The products have pesticidal properties (see Division A5).ALSO:A pesticidal composition contains as active ingredient an alkyl phosphorus-dithioate of the general formula <FORM:0952698/A5-A6/1> wherein R, R1, R2 and R3 are the same or different and are each a C1-C4 alkyl radical (see Division C2).  The composition may be in the form of a solid (e.g. dust) or liquid and specified solid carriers are talc, natural clays, diatomaceous earth, various flours e.g. walnut shell, wheat, soya bean and cotton seed.  Liquid compositions may be obtained by dissolving the active ingredient in a solvent such as kerosene, fuel oil, xylene or alkylated naphthalenes or a concentrated solution of the active ingredient in an organic solvent may be dispersed in water with the air of a surface active agent of anionic, cationic or non-ionic type.

Title: An improvement in or relating to looms for weaving having stationary weft supplies
IPC: D03D47/23
Filed: 1928-10-25
Abstract: 320,774. Gledhill, W. Oct. 25, 1928. Addition to 289,570. Shuttleless looms.-The gripper mechanism of looms having stationary weft supplies as in the parent Specification, is modified so that the delivering gripper a is relieved of the duty of opening the jaws f<1>, f<2> of the receiving gripper f shown in plan view in Fig. 1 and in elevation in Figs. 3 and 5, these jaws being opened instead by means of a projection i<2> on or by the shaped end of a bar i carried by but slidable, on the reciprocatable bar g carrying the receiving gripper. As this carrier bar g moves inward towards the gripper a, a pin n on a lever m pivoted to the bar g and engaging a slot in the bar i engages an inclined abutment o whereby the lever m is rocked and the bar i moved inwards on the bar g, so that the projection i<2> engages between tail pieces &c. f<3>, f<4> on and opens the jaws f<1>, f<2> against the action of a spring k. Pins i<3>, i<4> limit the opening movement of the jaws f<1>, f<2> and ensure closing thereof when the bar i is retracted. The abutment o may be a spring blade anchored at o<1> to the lay and resting on its lower end on a fixed part o<2>.The jaws f<1>, f<2> pass into a recess d in the delivering gripper, the pin n riding clear of the abutment o and a spring p then retracts the bar i thus permitting the jaws f<1>, f<2> to close on the weft end. As the carrier bar g moves outwardly again, the pin n rides beneath and raises the spring blade. At the end of the inward movement of the carrier bar g, and unless in the meantime the bar i has been retracted by the spring, the nose of the delivering gripper strikes an abutment i<5> on the bar i, thus positively retracting the bar i and ensuring the closing of the jaws f<1>, and f<2> on the weft in case for example the spring p should break. At the end of the outward movement of the grippers, the jaws f<1>, f<2> are opened by means of the usual member t to release the weft end for insertion in the salvage &c. In a modification the receiving gripper travels into the shed with its jaws open, the inner faces of the shanks f<2>, f<4> being so shaped that when the projection i<2> is in jawopening position, the jaws remain open. The jaws are closed by the part i<5> and opened by means of the member t. A second spring abutment may be provided at the outer end of the lay, and the bar i then utilised to open the jaws of the receiving gripper. Specifications 22659/01 and 190,266 are referred to.

Patent GB-636083-A (GB)
Title: Improvements relating to alternating current electric motor control systems
IPC: H02P9/10
Filed: 1947-11-21
Abstract: 636,083. Control of A.C. motors. MULLIGAN, J. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 21, 1947, No. 30959. [Class 38 (iii)] In a control system for an alternating-current synchronous motor the direct-current excitation of the motor is controlled in accordance with the load on the motor by means which is responsive to changes in the load current and in the exciting current and operates to control the exciting current such that the ratio of the exciting current to the load current is maintained substantially constant at a predetermined value. The said means is preferably so arranged that the excitation of the motor cannot be reduced below a predetermined minimum value. An exciter E is coupled to a synchronous motor M and supplies directcurrent to the rotor winding of the motor through slip-rings SR. The field winding F of the exciter is connected across its armature through a variable resistance RS which is adjusted by means of a servomotor SM. A relay BR, having a coil LC which is energized in accordance with the load current through a current transformer CT and a rectifier R, and an opposing coil EC which is energized in accordance with the exciting current through a shunt SH in the armature circuit of the exciter, controls the operation of the servomotor. If the ratio of exciting current to load current has a desired pre-determined value, the contacts of the relay will be open and the servomotor de-energized. If the load increases, for example, the servomotor is energized to reduce the resistance RS. The exciting-current is increased and the ratio between it and the load current is brought back to the pre-determined value, whereupon the motor SM is de-energized. Alternatively, the balanced relay may operate through contactor switches or a carbon pile regulator. A voltage regulator, transductor, or electronic apparatus may replace the balanced relay.
