Abstract: 1,228,546. Cutting machine with blade sharpening means. CINCINNATI MILLING MACHINE CO. 2 May, 1969 [31 July, 1968], No. 22645/69. Heading B4B. [Also in Division B3] A cutting machine comprises a reciprocable blade 16, means for removing the blade 16 from engagement with material 14 being cut, and a pair of drivable sharpening bands 49, 50, first means moving one band into engagement with one side of the blade edge 17 prior to removal from engagement with the material, and second means moving the other band into engagement with the other side of the blade edge prior to return, and means 101 co-operating with the first and second means to reduce the force required to move each band. A frame 26 bearing the blade 16 and its driving motor 24 is slidable on rods 27 by means of a cable 48 to engage or disengage the blade with or from the material being cut; a motor 38 governed by a feedback resolver 39 may rotate a box 40 supporting the blade in guide means 47 to change the heading of the blade. The sharpening bands 49, 50 are supported on a vertically fixed plate 52, rotatable in synchronism with the box 40 through gear means, Fig. 9 (not shown), including a ball spline 76, by means of drive pulleys 61, 65 of rotary cylinders 62, 66, Fig. 5 (not shown), and idler pulleys 60, 65, biased by springs 56, 59 to tension the bands, Fig. 6 (not shown). The pulleys 61, 65 may be driven by a motor 87 through a timing belt 88, annular gear 71 and idler gear 68. To engage the blade and the corresponding side of the guide member 47, one of the bands, e.g. 49 is urged outwardly by a lever 91, rigidly linked to a further lever 92 acted on by a solenoid 94 through a tension spring 93, which allows satisfactory sharpening irrespective of blade wear. On actuating the other band 50 retraction of the first is ensured by a turnbuckle connection 101, release of energy stored in the spring 56 during engagement of the first band 49 assisting in engagement of the other 50. The support rods 27 depend from a plate 28, transversely slidable on ways 36 above longitudinally fed input material, Fig. 1 (not shown), and numerical control apparatus (51) automatically governs the cutting process and sharpening cycles.

Abstract: 1,238,346. Carbon black. ASHLAND OIL Inc. 12 July, 1968, No. 33280/68. Heading C1A. [Also in Division H1] Carbon black may be prepared by contacting a hydrocarbon feedstock with hot combustion gases in a first combustion zone, into which feedstock is injected and turbulently mixed, introducing them into a second zone through a restriction of lesser cross-section than either zone, injecting Ca, Sr, Mg or mixtures of these into the reaction mass in the second zone, cooling the reaction mass at a distance downstream sufficient to provide a contact time between the alkaline earth metal and the black sufficient to increase the surface area of the black, and recovering the product. Alternatively, the feedstock is injected into the first zone as a conical spray having an average included spray angle of 60-180 degrees, the rate of introduction of feedstock and combustion gases being adjusted so that 20-70% of the feedstock is burnt, and the rest converted to carbon black at a temperature of 3000-3400‹ F., and the reaction mass contacted with alkaline earth metal (including Ba) for 10-70 milliseconds, cooling to below 3000‹ F., and recovering the black. The combustion gases are preferably provided in the first zone by igniting a mixture of fuel and air at the upstream end of the first zone as a radially outwardly directed disc-shaped stream which is initially out of contact with the feedstock. The metal may be introduced as a compound, and, if a mixture of metals including barium is used, variation of the weight ratio of Ba to total metal varies the "structure" (as measured by oil adsorption) of the product independently of the surface area. Blacks having surface areas (iodine absorption) of 600-1300 m<SP>2</SP>/g. ; structure levels (oil factor) of 250-450 ml./100 g. C; pH of 6-10 and ash contents 0À5-10% may be produced by these methods.

An hydraulically actuated disc brake having an automatic clearance-retaining device which returns the piston 13 independently of the magnitude of wear of the friction linings 3 to provide a constant clearance, is provided with a pin 19 firmly located in the base of the actuating cylinder 14, the pin being surrounded by a return spring 17 and having at least one clamping element 24 frictionally located on it; the return spring 17, which is supported against the clamping element 24 and is compressed on actuation of the brake, engages via an anchoring member 25 with the piston 13 and removes the piston from the brake during release of hydraulic pressure, the anchoring member 25 being engaged as a snap-fit with the piston. Fig. 2 shows the significant features of Fig. 1 to a larger scale, and differs from Fig. 1 only in insignificant detail (see below). In Fig. 1, a pin 19 is firmly located in a bore 21 in the end 18 of a cylinder 14. Clamping elements 24, which are not normally slidable on pin 19, are frictionally mounted thereon. A release or return spring 17, preferably formed as a dished ring, surrounds pin 19, and is engaged by an anchoring member 25 formed from three segments, Fig. 3, held together by a resilient wire ring 28. The inner end 27 of the anchoring member is in-turned and engages the edge 31 of a collar 26 formed on the end of a piston 13. The edge 31 of collar 26 and the edge 32 of the end 27 of member 25 are tapered to facilitate engagement on assembly. In operation, when liquid under pressure is introduced into space 15, piston 13 is moved to the right, entraining the anchoring member 25 which thereupon flattens spring 17 against clamping elements 24. Floating saddle 1 is moved to the left by reaction. On release, spring 17 resumes its curvature, restoring the parts to their Fig. 1 positions. Brake shoe wear is taken up when necessary by progressive movements of the clamping elements 24 along the pin 19 during forward movement of the piston. In fixed saddle brakes, a cylinder is provided on each side of the brake disc, each cylinder being fitted with a clearance-retaining device. In Fig. 1 the cylinder head is recessed to accommodate the anchoring member 25, while in Fig. 2, the piston end is recessed instead.
