Abstract: 1,064,736. Abrasive tools. UNION TANK CAR CO. Dec. 12, 1963 [Dec. 26, 1962], No. 48329/64. Divided out of 1,064,735. Headings B3C and B3D. A method of cooling and lubricating a cutting surface of a rotating hollow cutting tool comprises feeding a cooling and lubricating liquid under gravity to a portion of the cutter remote from the cutting surface, confining said liquid on the cutting tool against the action of rotational forces tending to fling said liquid radially beyond said cutting tool, directing flow of said liquid into the interior of said cutting tool and providing an unobstructed path on the interior of said cutting tool to permit said liquid to reach the cutting surface due to the action of the rotational forces. A rotary cutter 90 for cutting a hole in a sewer main (11) has a hollow cylindrical metal body 91 with an open end having a cutting edge 95 of diamonds in a matrix. The other end, which is secured to the driving shaft 28, has one or more openings 96 surrounded by a peripheral rim 97 having an inwardly bevelled edge 98. Cutter cooling and lubricating liquid from a tank (60) flows by gravity through a pipe 40 on to the end of the cutter and is flung centrifugally towards the outer periphery, the rim 97 acting as a barrier preventing the liquid from leaving the cutter and causing it to flow through the openings 96 to the interior of the cutter. It flows down the inside surface of the cutter and thence outwardly from the cutting edge 95.

[Also in Division A4]  A brush having bristles formed integrally with a backing portion is injection moulded in a mould cavity comprising a number of plates 8 forced together in face to face relation, the plates having staggered rows of slots 10 providing bristle forming cavities which connect with a further cavity providing the backing portion. Each bristle may be of tapering shape with a forked end. In a modification, the slots are not staggered, and each pair of slotted plates has a separator plate therebetween. The edges of the slots may be bevelled; some of the slots may be blanked off during the moulding to provide an unbristled area of a desired pattern. The injection moulding apparatus of Fig. 17 has two sets of slotted plates or laminations 95 fed with moulding material, e.g. polyethylene or polypropylene, via a nozzle 52 and passages 54, 55 to produce two brushes 100. The laminations of each set are carried by pins 90 and forced together by end blocks 91 with outer inclined surfaces which co-operate with similarly inclined surfaces of plates 85 fixed to an upper mould part 57. The plates 85 are slotted to receive the ends of the pins 90, and when the parts 57 and 58 are separated at the end of the moulding stage springs 96 push the sets of laminations downwards allowing adjacent laminations to move apart; a plate 56 is moved away from the part 57 by springs 80. The moulded brushes are retained on the lower mould part and are removed therefrom by an ejector 68 with upstanding pins 72 forced upwardly by a rod 69. A floor tile with upstanding bristles may be similarly produced.
