Abstract: 557,379. Cow-milkers. AKTIEBOLAGET SEPARATOR. Oct. 17,1941, Nos. 13384 and 13385. Convention date Oct. 17, 1940. [Class 84] [Also in Group XXVI] A pneumatic pulsator, particularly for milking machines, comprises a piston valve n controlling the connections to atmosphere and a source of suction of nozzles m, m<SP>1</SP>. For preventing 'too rapid vibration, diaphragms d are connected to or associated with one or both ends of the piston, such diaphragms acting as dampers on the reversal action. The chambers t, u are connected by a narrow, adjustable passage 10, Fig. 4, through which the pressure above or below atmospheric built up in the chamber u during each piston stroke is but slowly dissipated. A liner e separates the housing a from the valve n. Annular passages in the valve surface connect the ports k, k<SP>1</SP> alternately to the suction pipe i and atmospheric ports g', g, and also by way of axial conduits o, r to the piston faces and chamber t. The diaphragm d is set so that in the inoperative position the valve is just off the dead-centre position; pulsation may also be started by pressing the pin 14. Diaphragms may be associated with each end of the valve which may be mounted on a milk-pail with its axis vertical. The tendency of the valve to fall due to its own weight may then be counteracted by making the lower members correspondingly larger.

Title: Improvements in or relating to insecticides
Filed: 1935-05-07
Abstract: An insecticide for destroying locusts comprises an alkali metal zincate and one or more aromatic hydrocarbons or derivatives thereof, for example, tar-oil or creosote.  It may be prepared by reaction of zinc or a compound thereof with aqueous alkali metal hydroxide in the presence of the hydrocarbon or its derivative. With metallic zinc the reaction proceeds at ordinary temperatures in the presence of iron. The hydrocarbons or derivatives also appear to act as catalysts and by adding them before or with the zinc they are emulsified, owing probably to the effervescence produced.  The reaction is allowed to proceed for at least 30 mins. and the liquid withdrawn.  A concentrated solution may be prepared and diluted for use as a spray which may contain 1-15 per cent and preferably a minimum of 2 per cent of sodium zincate. At this preferred concentration the amount of hydrocarbon may be 20-500 g./100 1. water.  Potassium or lithium zincates, or mixtures of alkali zincates can also be used.
