Title: Improvements in rubberized blown asphalt and method for making same
Inventor: ODASZ FRANK BERNARD
IPC: C10C3/04
Filed: 1960-06-15
Abstract: Rubberized asphaltic compositions, for use as fillers in road building, waterproofing or paper laminants where good low-temperature properties are desired, consist of an asphalt blown to a softening-point of from 80 DEG  to 165 DEG  F. and rubber solids (e.g. 0,1% to 10% by weight based on the weight of asphalt) such as neoprene, butadienestyrene copolymers or natural rubber.  The compositions are produced by air blowing (e.g. at 400 DEG -450 DEG F.) an asphalt flux, such as derived from natural or cracked, straight-run or vacuum-reduced asphalts, and having a viscosity of from 40 to 300 SFS at 210 DEG  F., in the absence of any catalyst, to the above mentioned softening-point, and interblending the resultant blown asphalt with the rubber by introducing it, preferably by injecting it, in the form of an aqueous latex, into a hot (e.g. 450 DEG -600 DEG  F.) molten highly fluid body of the blown asphalt, preferably flowing at a constant rate in a confined stream, so that the latex-water is flashed into steam upon contact with the asphalt causing vigorous agitation, whereby the rubber is intimately dispersed, and causing a sudden lowering of the temperature of the resultant mixture to below that (but not below 325 DEG  F., preferably 350 DEG -400 DEG  F.) at which the rubber is deleteriously affected, prior to the mixture being discharged into an open vessel where the steam may escape. Specifications 886,883, 886,885 and U.S.A.  Specifications 2,921,105 and 2,921,313 are referred to.ALSO:Rubberised asphaltic compositions, for use as fillers in road building, waterproofing or paper laminants where good low-temperature properties are desired, consist of an asphalt blown to a softening-point of from 80 DEG  to 165 DEG F. and rubber solids (e.g. 0,1% to 10% by weight based on the weight of asphalt) such as neoprene, butadiene-styrene copolymers (GRS) or nuatral rubbers.

Filed: 1969-04-25
Abstract: 1,263,153. Spray producers. ELSWORTHY ELECTRONICS Ltd. 24 April, 1970 [25 April, 1969], No. 21233/69. Heading B2F. An ornamental spray device, e.g. for garden ponds, comprises, Fig. 1, a submersible casing 1 containing a water pump, a riser tube 5, and a rotatable head assembly 6 having spray tubes 9, 10 with apertures 11 through which water from the pump is sprayed to cause the head assembly to rotate. The tubes 9, 10 are a friction fit in T-piece 8 so that they can be twisted with respect to the T-piece, thus altering the spray pattern and speed of rotation of the head assembly 6. The casing 1 is of moulded plastic having a water intake 3 with a screen. The pump is driven by an encased electric motor through a magnetic coupling. The head assembly 6 may be rotatably secured to the riser tube 5 by a spring clip (16), Fig. 2 (not shown), engaging in cooperating grooves. In a modification, Fig. 3, the spray tubes 17 are secured to the #- piece 18 by bayonet joints 20, O-rings 23 ensuring that the bayonet joints are water-tight. The T-piece 18 is rotatably supported on the riser tube 25 by the engagement of a shoulder 26 on the latter with a shoulder 27 on a tubular member 28 forming part of the rotary assembly. In further modifications, one or more of the spray tubes may be inclined to the horizontal or may be curved. The tubes may be equi-angularly spaced about the axis of rotation or asymmetrically disposed, balance weights being used in the latter case.

Abstract: 810,727. Valves. SMITH, E. M. July 22, 1955 [Aug. 2, 1954], No. 21332/55. Class 135. A valve comprises a body with a cylindrical cavity 160 having an end shoulder 164 surrounding an inlet 120a, a resilient split sleeve 105 resting on the shoulder and sealing with the cavity wall, a rotary plug 112 in the sleeve containing a bore 161 leading from the inlet to an aperture in the sleeve, and means enabling the sleeve to rotate with the plug to control the connection between the inlet and an outlet. The rotary cylindrical plug is surrounded by the longitudinally split sleeve having ports coinciding with ports in the plug. The sleeve is carried around by the plug when it is rotated by the ends at the split being inturned at 126, 127 into a slot 124 in the plug. The sleeve also presses sealingly against the wall of the casing bore containing the plug. When fluid flows from the inlet to one of the outlets 120, 121a, fluid seeps between the sleeve and the plug and presses the sleeve sealingly over the outlet not being used. The plug may have an axial bore connected to two right-angled bores, as shown, so that one outlet or the other may be used with a 45‹  rotation of the plug or the plug may have an axial bore and one right-angled bore so that 180‹ rotation is necessary.
