Title: Improvements in or relating to mowing machines
IPC: A01D34/07
Filed: 1965-04-27
Abstract: In a mowing machine wherein the cutter-bar (42) is pivoted on a bracket (12) carried at the end of drag-bar (9) forming part of a frame (1, 2) attached to tractor lift-links (67, 69) the bracket (12) is adjustable slightly longitudinally of the drag-bar whereby the fixed finger-beam (20) can be moved longitudinally relative to the reciprocable knife-bar (41).  The inner end of the cutter-bar carries a bracket (18) pivoted about horizontal pins (16) to the brackets (12) which includes a sleeve-portion (11) rotatable on the end (10) of the drag-bar (9).  Both the sleeve and the drag-bar carry upstanding slotted standards (34, 37) which are secured together by an arm (36) passing through the aligned slots in the standards.  The standards are adjustably spaced longitudinally of the drag-bar by shims (39) encircling the arm, the number of shims being variable at will.  The bracket (34) on the drag-bar is adjustable, relatively to the other bracket, by rotation of a knurled knob (38) having a screw-threaded connection with the arm (36) whereby the cutter-bar can be rotated about the axis of the drag-bar to alter its fore-and-aft pitch.  The drag-bar and cuter-bar are pivotally movable about a vertical axle (4), on the frame by adjustment of a turn buckle (54) forming part of an elbow-joint (50, 54) which normally prevents pivotal movement, one arm (50) of the elbow-joint being integral with a vertical pivot (49) which is also integral with a cam-disc (60) having a spring-loaded locking-mechanism (58, 59, 64). Excessive resistance encountered by the cutter-bar releases the locking-mechanism permitting the drag-bar to swing about the vertical axle (4).  When this happens, a bell (46) carried by the driving-crank (45) of the mower contacts a stationary spring-mounted striker (47) on the frame, to warn the tractor-driver of the break-back.  Lifting of the cutter-bar (42) about its pivot-pins (16) is effected automatically by the lower lift-links (67) engaging the end (31) of a lever (29) pivoted on the frame (1, 2) and attached by a chain (28) and links (26, 25, 23) to the bracket (18) on the cutter-bar.

Title: Improvements in or relating to the production of polyvinyl synthetic resins
IPC: C08K5/33
Filed: 1938-06-15
Abstract: 516,118. Polyvinyl acetal resins. KODAK, Ltd. June 15, 1938. No. 17848. Convention date, June 23, 1937. [Class 2 (iii)] Polyvinyl acetal resins are stabilized by subjecting them or their polyvinyl intermediates to the action of a compound containing an : N.OH group, or a salt thereof, preferably before the resin has been heat-dried. The use of hydroxylamine before heat-drying is disclaimed. Thus the treatment may be applied to the acetal, to a polyvinyl alcohol or ester used in its manufacture, or to a reaction mix of aldehyde and polyvinyl alcohol or ester. There are specified : polyvinyl acetal resins-formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, formaldehyde-, butyraldehyde-, benzaldehyde-, furfuraldehyde-, acetone-, and cyclohexahone-acetaldehyde acetals ; polyvinyl intermediates-polyvinyl esters, e.g., acetate and chloride-acetate ; : N.OH compounds -hydroxylamine and substituted hydroxylamines, e.g., phenylhydroxylamine and nitrosohydroxylamine'; oximes, e.g., acetoxime, ,butyraldoxime, salicyloxime, dimethylglyoxime ; and hydroxamic acids R-C (OH) NOH (where R is hydrogen or alkyl). Acetals containing hydroxyl groups may be treated, thus a polyvinyl butyraldehyde partial acetal prepared according to Specification 459,878, may be dissolved in alcohol before heat-drying and treated with an : N.OH compound. The products may be used in films, e.g., photographic films and interlayers for laminated glass, wood, metal, paper or cellulose esters, and wrapping materials and in artificial yarns, lacquers, moulding compositions, impregnated textiles and electrical insulation : there may be added to them other plastic materials, e.g., cellulose esters (e.g., acetate, acetate-propionate, acetate-butyrate), cellulose esters (e.g., ethylcellulose), oils, waxes, gums, and natural or synthetic resins. In examples : polyvinyl acetate is reacted with paraldehyde in the presence of phenylhydroxylamine, acetoxime, butyraldoxime, salicyloxime, or dimethylglyoxime. Specifications 513,266 and 518,099 also are referred to. According to the Specification as open to inspection under Sect. 91, the invention applies to polyvinyl resins broadly and to : N.OH bodies broadly. This subject-matter does riot appear in the Specification as accepted.

Abstract: 941,020. Apparatus for loading tyre retreading moulds. SUPER-MOLD CORPORATION OF CALIFORNIA. May 15, 1962 [July 27, 1961], No. 18706/62. Heading B5A. [Also in Division B8] The apparatus consists of a movable two-part mould matrix and a mechanism arranged to move through the lower mould part to receive the tyre and deposit it in the mould. The mould matrix is lifted, using the crane 13 (Fig. 1), into position above the supporting pads 19, 21 which are at the same level. The mould is lowered and locked into position when pins 45 enter the locking units at pads 19, 21. The mould locking ring is released and the crane 13 removes the upper mould half 42 to a remote position. The tyre 49 containing a curing bag 50 and a curing rim 51 is lowered into position by means of a tandem power cylinder assembly 52 mounted centrally and vertically in the frame 1. Piston-rod 56 connected to power cylinder 55 passes freely through the lower mould half 41 and through the cylinder head 63 which is part of a lower tyre bead engaging disc and travels with the power cylinder 55. The piston-rod passes freely through an upper tyre bead engaging disc 66 which has means for engaging the disc to the rod 56. To load the tyre the upper disc 66 is removed when the power cylinders 53, 55 are contracted. The lower cylinder 53 is then extended so that cylinder 55 and head 63 are also raised until the lower head engaging disc is above the lower matrix half 41. The tyre is then lifted by the other crane 13 and deposited on to the lower disc 65. The upper disc is placed on the tyre and piston 56 run upwards until it engages with the upper disc 65. The upper power cylinder 55 is contracted so that the tyre beads are forced together. This draws the sidewalls about the curing rims 51 and reduces the outside diameter of the tyre so that it freely enters the lower mould half 41 when the lower power cylinder 53 is contracted. The upper mould half is then replaced. The piston 55 is extended so that the rod 56 passes through the upper mould half to engage in a horizontal pressure bar 74 which is manually placed above the upper matrix half 42. The upper power cylinder 55 is then reversed so that the rod 56 is retracted and the pressure bar 74 forces the upper mould half 42 into concentric registration with the lower mould half 41. The mould halves are locked together and the pressure bar 74 is removed. The tyre is inflated, the upper disc 66 is removed, pins 45 released and the mould transported to a vulcanizing apparatus.
