Title: Lawn sprinkler
IPC: B05B3/16
Filed: 1962-12-17
Abstract: 952,728. Lawn sprinklers. SUNBEAM CORPORATION. Dec. 17, 1962 [April 18, 1962], No. 47539/62. Heading B2F. An oscillating sprinkler comprises a water motor operable to oscillate a pivotally mounted carrier means 40, 46 for an elongated spray tube 38 about a horizontal axis, the spray tube being also mounted so that it can be positioned at various angles to the said axis for adjusting the width of the spray pattern. As shown, the sprinkler casing is made up of two plastic or die cast members, a combined base and housing 14 and a cover 16, the housing having a pair of runners, such as 14b, which support the spinkler on a lawn. The spray tube 38 is carried by a vertical conduit 40 which is mounted for rotation about its vertical axis in a cylindrical member 46, the latter being constantly oscillated about its horizontal axis in the housing 14. The conduit 40 is urged downwardly by a coil spring 44, is oscillated by the member 46 through an arc which is adjustable between 45 and 90 degrees, and can be adjusted about its own vertical axis to swing the longitudinal axis of the tube 38 relative to the casing to give a spray width varying from one to sixty feet. The water motor consists of an impeller 22, driven by water forced through an orifice 16c in the. hose connection 16a, which drives a shaft 34 through a system of worm gearing. An eccentric 36 secured to the shaft 34 engages an elongated slot 58a in the lower end of a link 58 pivoted on a boss 62b, and a pin 60 secured eccentrically to the bottom wall 46b of the member 46 engages a slot 58b in the upper end of the link 58. Thus, as the impeller 22 is driven by the water, the link 58 is oscillated about the pivot boss 62b, and the cylindrical member 46 is also oscillated about its horizontal axis, which is coincident with that of a shaft 54. The shaft 54 carries a setting knob 52 at one end, has a link 66 secured at its other end, and is rotatably mounted in bearings in the housing 14 and cover 16. The lower end of the link 66 is so connected to a support arm which carries the pivot boss 62b, that rotation of the shaft 54 by the knob 52 produces a vertical movement to the pivot boss 62b. This vertical adjustment of the pivot 62b causes the degree of arc through which the member 46 is oscillated to vary between 45 and 90 degrees, so that the length of spray is varied.. Scales and pointers assist the setting of the control knob 54 and of the vertical support 40. Water leaving the impeller 22 passes to the spray tube 38 through the member 46 and support 40.

Title: Phosphorus isocyanide dihalide compounds
IPC: C07F9/44
Filed: 1963-12-03
Abstract: The invention comprises phosphorus isocyanide dihalides, of the formula <FORM:1002235/C2/1> wherein R1 and R, which may be the same or different, represent C1-C6 alkyl, alkoxy, or alkylthio radicals or aryl, aralkyl, arylthio, aryloxy, dialkylamino or diarylamino radicals, X is oxygen or sulphur, and Hal represents Cl or Br. The compounds are prepared by chlorinating or brominating substituted phosphoryl mustard oils (allyl isothiocyanates), of the formula <FORM:1002235/C2/2> when sulphur dihalide and the desired phosphorus isocyanide dihalide are formed.  The reaction is conducted at -50 DEG to +150 DEG  C., preferably at 0 DEG  to 100 DEG  C., suitably in an appropriate inert solvent, with a chlorination catalyst, (e.g. AlCl3; FeCl3; TiCl4).  Examples are given for preparation of: diethoxy-, diphenoxy-, di-n-butoxy-, and di-isobutoxy-phosphoryl isocyanide dichloride; and diethoxy-, and dimethoxy -thiophosphoryl isocyanide dichloride; the compounds may be reacted with thioalcohols to give substances useful as insecticides; an example is given for reaction of diethoxyphosphoryl -isocyanide dichloride with dithioethylene glycol to give 2-(di-ethoxy phosphorylimino)-1,3-dithiolane. The compounds are also useful as intermediates for the preparation of oil additives. Specification 974,138 is referred to.

Abstract: 1373867 Hydraulic pulse generators; reciprocating pumps VSESOJUZNY NAUCHNOISSLEDOVATELSKY KONSTRUKTORSKY 1 TEKHNOLOGICHESKY INSTITUT GIDROMASHINOSTROENIA 18 Oct 1972 47990/72 Heading F1A and F1P In a hydraulic pulse generator comprising a spring-loaded piston 7, Fig. 1, driven by an eccentric 4, fluid passes through an axial hole in the piston from a reservoir in the body 1 to make up any losses during the return stroke when an annular ring on a valve 16 is moved away from the piston end face by a spring 19. During the compression stroke the valve 16 is moved towards the piston by the eccentric 4 and when the ring abuts the piston the latter is moved against the spring 15. If the output pressure rises undesirably the piston moves further to the left away from the sealing ring on the valve because the effective area of the piston is less than that . enclosed by the sealing ring. The ratio of these areas is between 0.99: 1 and 0.66: 1. In a second embodiment, Fig. 3, for providing small pulsating supplies, both piston and cylinder are of stepped form and a bore 20 connects the cylinder 6 with the reservoir. Pulses are transmitted through an orifice 10. The device may be used to drive a diaphragm pump or an actuator.

Abstract: 1,005,792. Concentrating heat-sensitive liquids. UNION CARBIDE CORPORATION. Dec. 19, 1962, No. 48040/62. Drawings to Specification. Heading A2D. Heat-sensative materials in liquid form such as fruit or vegetable juice, beer, wine, coffe, milk, or resin or pharmaceutical (antibiotic) in liquid form, are concentrated by subjecting them to a stripping operation by passing an inert gas through the material to remove most of the dissolved oxygen content, removing the organic flavouring constituents or "essence" from the oxygenstripped material and concentrating the material from which the essence has been removed by evaporating solvent while subjecting the material to a pressure less than atmospheric, the essence and the material being constantly maintained in a nonoxidizing atmosphere, and the essence and the concentrate material are then recombined and stored under non-oxidizing conditions. The oxygen content of the material after the stripping operation should be less than 0.4 part per million. The essence is removed from the material either by subjecting the material to a pressure less than atmospheric or by heating the material up to a temperature not exceeding 88‹C, passing an inert gas through the heated material to strip the essence from the material, passing the inert gas and entrained essence through a cooling zone to condense the essence, the remaining non-condensed essence and the stripping gas being passed into a cooled body of the material being treated which absorbs and/ or dissolves the remaining essence, and then reconducting the stripping gas to the heated material for another cycle. Inert gases mentioned are nitrogen, argon, hydrogen, helium and carbon dioxide. A portion of the stripped material may be cut-back to control the concentration of the blend of essence and concentrate material. The concentrated product may be canned and stored in a refrigerator. Specification 1,005,793 is referred to.
