Abstract: 1,028,743. Cutting tools. BROWN - McLAREN MANUFACTURING CO. June 6, 1963, No. 22651/63. Heading B3B. A form cutting tool comprises a holder 10 with a shank 14, for securing to a machine tool, and a cutter 12. The cutter is formed by a stack of cutting elements or bits 18, 20, 22, 24 which are identical in shape and interchangeable. The topmost cutting bit effects the cutting action on a workpiece and when resharpening becomes necessary this bit can be removed and the stack moved up so that the second bit may perform the cutting operation. The tool holder has a forwardly extending portion 40 through which a clamping screw 44 extends to clamp the bits against the portion 40. The rear portion of the cutting bits and their clamping block are formed with a dovetail which engages a dovetail slot in the holder 10 which is provided with a detachable side portion 34. The holder 10 may be of one piece construction or be made in two parts 48 and 50, dovetailed together, the adjacent faces of the two parts including the dovetail being arcuately curved on a radius extending from the outermost part of the cutter cutting edge. This two-part holder construction facilitates angular adjustment to vary the angle of rake of the cutter 12, without effecting the setting of the cutting edge of the tool. The adjustment may be effected by an adjusting screw 64 located on the holder part 50 in co-operation with a lever 60 on part 48, the lever being movable in relation to a fixed scale 70.

Title: Process for making high polymers of alpha-methyl styrene
IPC: C08F12/12
Filed: 1950-09-15
Abstract: A high molecular weight polymer of alpha-methyl styrene is prepared by maintaining a mixture consisting of alpha-methyl styrene and finely-divided metallic sodium at a temperature between 0 DEG  and 30 DEG  C., preferably 10 DEG  and 25 DEG  C., until from 20 to 35 per cent of the alpha-methyl styrene is polymerized, the mixture thereafter filtered to separate the particles of metallic sodium from the solution of polymer in monomeric alpha-methyl styrene, and the polymer recovered from the filtered solution. The amount of metallic sodium in the mixture is preferably between 0.5 and 10 per cent by weight of the alpha-methyl styrene.  The polymer preferably has a molecular weight corresponding to an intrinsic viscosity in toluene of at least 0.4 and contains approximately 0.06 per cent of its weight of chemically combined sodium; it may be recovered from the filtered solution by distilling at 170-190 DEG  C. at a pressure of 10 mm. or less for approximately 10 hours.  The process may be carried out in continuous manner by feeding monomeric alpha-methyl styrene to the reaction mixture of finely-divided sodium, alpha-methyl styrene and polymeric alpha-methyl styrene, and withdrawing reaction liquor consisting of a solution of from 20 to 35 per cent by weight of the polymer in monomeric alpha-methyl styrene through a filter, the filtered solution being distilled to separate the monomer from the polymer, and the monomer recycled to the reaction.

Title: Bale divider inserter
IPC: B30B9/30
Filed: 1968-05-14
Abstract: 1,236,086. Baling machines. HUGH F. MUNRO & SONS Inc. 14 May, 1968 [15 May, 1967], No. 22878/68. Heading B5F. In a machine for baling, e.g. waste paper, bale dividers 20a, 20b stored in a magazine 51 are serially inserted through a door 82 in the wall 80 of a baling chamber 100 by means of a pusher 60 reciprocated by an hydraulic cylinder 92. In order to prevent the divider being retracted with the baling plunger, a looking arm 65a pivoted at 61 to the pusher 60 is moved to the dotted line position in Fig. 6 to tilt the divider 20a. Pivoting of the arm 65a occurs when a finger 66 connected thereto contacts a block 58. The magazine 51 is provided with internal top and bottom sloping guides (55, 56) for the dividers (Fig. 4, not shown). A latch 74 on a bar 70 pivoted at 71 is adapted to engage a stored divider 20b and hold it in place to prevent it interfering with the mechanism for inserting the divider 20a. When the pusher 60 is retracted (Fig. 3a) a cam 69 thereon engages a follower 73 on the bar 70 and withdraws the latch 74. The stored divider is thus released and is moved by gravity and a leaf spring (54) into position ready for insertion. The door 82 is hinged at 81 and is movable to the closed position by a spring (87), Fig. 5 (not shown). When the door is partially closed a cam (83) on the door hinge 81 is engaged by a spring-biased follower (84a) and holds the door in a partly closed position. This prevents the divider from toppling backwards. On the next stroke of the baling ram (90) the door 82 will close completely. Grooves in the faces of the dividers (Fig. 2, not shown) facilitate the passage of baling wires.

Abstract: 1,174,078. Liquid-dispensing apparatus. VEE DER INDUSTRIES Inc. 16 May, 1968 [15 Feb., 1967], No. 23465/68. Heading G4D. Apparatus of the type described in Specification 1,110,159 is modified in that at the end of a dispensing operation rotation of the usual control lever to off loads a spring for subsequent resetting of the registers. In the earlier Specification this loading is effected as a preliminary to removing the nozzle from its holder. In the present case turning the control lever (14) to off rotates control plate 18 counter-clockwise from fueldelivering position, Fig. 1, carrying along reset drive plate 22, through the medium of pawl 24 and so loading spring 32. A latch pawl 50 engages a shoulder 52 in plate 18. The registers are now held in known manner displaying the valves relating to the completed delivery. At the next dispensing operation turning the control lever (14) to on acts first to rock trip shaft 79. In known manner (Figs. 4, 5, not shown) the first part of this movement shifts a slide (36) to the left to condition the registers for resetting. The tail 80 of pawl 50 releases pawl 24 so that spring 32 drives reset drive plate 22 clockwise. A gear 42 integral with the plate 22 drives gears (not shown) to restore the registers in known manner. As plate 22 completes its movement its shoulder 90 cams pawl 50 further to release control plate 18 which is then rotated clockwise by a further spring (28) to the position shown in Fig. 1. The additional movements of shaft 16, fixed to plate 18, and rock trip shaft 79 return the slide (36) to the right to condition the registers for dispensing again, the pump motor being energized in known manner. Control of the apparatus is effected by a module comprising two lost-motion devices. There are two embodiments (Figs. 2, 3, not shown, and Figs. 6, 7, not shown).
