Abstract: A vortex-producing chamber has an inlet from the surface of a pool and an outlet at the bottom of the vortex chamber. A vortex is formed at this outlet which carries the water with any floating debris and the like with it into a tank from which it can be drawn out by action of a suction pump. In the usual arrangement, means such as a float is located in an upper portion of the tank at the water surface. If the tank water level drops abnormally low the float means comes down with the water and engages a seat dividing the upper and lower tank portions from each other and sealing the lower tank portion from air in the upper portion. A bypass conduit leading from a water source such as the pool itself supplies water to the lower tank portion to supply the pump demand when the lower portion is thus sealed from the upper portion.

Abstract: A CABLE CLAMPING AND CUTTING DEVICE COMPRISING A BODY HAVING A BORE THROUGH WHICH THE CABLE PASSES AND A HOLLOW NUT THREADABLE INTO THE BODY, SO THAT THE CABLE PASSES THROUGH THE NUT AND THE BORE. TAPERED WEDGING ELEMENTS ARE PLACED WITHIN THE NUT WHICH ENGAGE CORRESPONDINGLY TAPERED INNER SURFACES OF THE NUT SO THT WHEN THE NUT IS TURNED ON THE THREADS THE WEDGE MEMBERS GRIP THE CABLE. THE BODY PORTION HAS A SECOND BORE, INTERSECTING THE FIRSTMENTIONED BORE, IN WHICH A PUNCH MAY BE INSERTED, WHICH WHEN STRUCK A BLOW WILL SEVER THE CABLE WITHIN THE BODY WHILE THE CABLE IS CLAMPED. THE BODY CONTAINS AN EYE MEMBER WHICH CAN BE ENGAGED BY A SUITABLE HOOK OR THE LIKE AS CABLE TERMINATION.

Abstract: THE DISCLOSURE SHOWS A SPRING LOADED WEIR IN A SKIM TANK SYSTEM USED IN A SWIMMING POOL, THROUGH WHICH WATER IS CIRCULATED TO A FILTER. THE WEIR COMPRISES A SHEET OF SPRING MATERIAL SUCH AS LEAF SPRING FIXED AT ITS LOWER EDGE AT THE BOTTOM OF THE THROAT LEADING INTO THE SKIM TANK FROM THE POOL, AND IS PROVIDED AT ITS UPPER FREE EDGE WITH A LIP MEMBER WHICH IS OF A DENSITY AND DIMENSION TO CAUSE IT TO FLOAT AT THE SURFACE OF THE WATER WHEN THERE IS NO WATER FLOWING THROUGH THE TANK. WHEN WATER FLOWS FROM THE POOL TO THE TANK, AS WHEN A CIRCULATING PUMP IS TURNED ON, THE WEIR IS BENT DOWN SO THAT WATER CAN FLOW OVER THE LIP INTO THE TANK.

Abstract: 1,124,368. Spray-producers. SWIMQUIP Inc. 12 Sept., 1966 [22 Oct., 1965], No. 40633/ 66. Heading B2F. An intermittently rotated sprayer suitable for watering or cleaning comprises stationary body members 10, 15, 20, a hollow generally cylindrical plunger member 27 located between cylindrical surfaces 23a, 26 and biased downwardly between further members 23, 32 by a spring 34, and a pipe 12 adapted to supply water intermittently to the housing formed by the members 10, 15 whereby the plunger 27 is reciprocated. Radial webs 19 beneath the member 20 define a plurality of outlet ports 21 and a pin (43), Fig. 6 (not shown) on the plunger cooperates with cam surfaces (41), (42) on the member 23 so as to rotate the plunger on each reciprocation by an amount which registers an outlet orifice 39 in the side wall of the plunger with an adjacent part 21. Tongues on a flange 31 on the plunger cooperate with grooves in the member 32 in order to guide the plunger and prevent relative rotation between the plunger and the said member. The intermittent water supply is controlled by a motor-actuated valve V. The top of the plunger is closed apart from a vent hole 29 and slits in the lower portions of the plunger side walls prevent grit &c. from building up at the spring. The member 20 may be attached to the plunger or may be removed altogether.
