Abstract: ABSTRACT OF THE DISCLOSURE        Some new phosphinic acid derivatives of amino-thio methylcarbamates have been synthesized and tested as pesticides. The new compounds are active against insects, mites, and nematodes. The N-[(phos-phinyl)amino]thio- and N-[(phosphinothioyl)amino] thio- methylcarbamates are readily prepared by the general procedure of reacting a phosphinic acid amide with sulfur dichloride so as to obtain the corresponding N-(chlorothio)phosphinic acid amide which reactant will react with a methylcarbamate so as to produce the corresponding object compounds, the N-[(phosphinyl)amino]thio- and N-[(phosphinothioyl)-amino]thio- methylcarbamates of this invention. Various formulations for pesticidal use are described along with appropriate rates of application.

Abstract: IMPROVED DEVELOPING APPARATUS                  ABSTRACT OF THE DISCLOSURE         If developer within a xerographic developing app-aratus becomes excessively charged, excessive toner is added to the apparatus because the excessively charged developer prevents a sensor from sensing the actual toner density within the apparatus.  To overcome this problem, an element (contacted by the developer during movement of the latter within the apparatus) is connected to ground through a surge voltage protector.  This prevents both the element and the developer from being excessively charged.

Abstract: ANIMAL TRAP            ABSTRACT OF THE DISCLOSURE         A swingable frame or trap bar component is pivotally mounted by one end thereof to one end of a stationary frame which includes a pair of spaced and parallel side frames ex-tending upwardly from a base.  A heavy duty coil spring nor-mally urges the trap bar component to be released or vertical position.  A trigger plate pivoted to the base and is held in the set position by a trigger pivotally mounted on a cross bar between the side frames, said trigger overlying the distal end of the trap bar component when the same is placed in the set position parallel to the base and against pressure of the spring.  The trigger engages under the trigger plate to hold the trap in the set position.  A sloping cross piece on the trap bar component is engaged by the trigger which is slidable across the cross bar enabling a degree of sensitivity to be imported to the release of the trigger by depression of the trigger plate.  When released, the trap bar component pivots around a mounting point swinging in an arc between the side frames and traps the animal between the trap bar component and a stop cross bar extending between the side frames substantially above the mounting point of the trap bar component and the spring, which urges it to the release position.
