Title: Metal-containing azo dyestuffs
Inventor: SCHUNDEHUTTE KARL-HEINZ
IPC: C09B45/24
Filed: 1964-11-25
Abstract: The invention comprises metal complex dyes of the general formula (I) <FORM:1091454/C4-C5/1> wherein X is hydroxyl or an acyloxy or acylamino group, the acyl group being derived from an aliphatic carboxylic or sulphonic acid having up to 7 carbon atoms in the aliphatic radical or from a benzene carboxylic or sulphonic acid, A is a mono or dinuclear aromatic residue of the benzene or naphthalene series in which the oxygen atom is attached to the o-position to the left-hand group, Me is a complex linked metal atom e.g. copper, and K is one of the formulae (II) <FORM:1091454/C4-C5/2> (III) <FORM:1091454/C4-C5/3> or IV <FORM:1091454/C4-C5/4> wherein B is a mono or dinuclea aromatic residue of the benzene or naphthalene series the -O-Me-O- group being linked to B and E respectively in the adjacent position to the azo group, D is a dinuclear aromatic residue of the naphthalene series in which the two nitrogen atoms of the triazole grouping are attached to the aromatic residue in the o-position to one another, E is a radical of an enolic or phenolic coupling component, R is hydrogen or a substituent and W is the radical of a mono- or polyfunctional acylating component to which further organic radicals can be linked through amino, thio or ether groups and the naphthalene radical in the first above formula, A and K may contain further substituents. Conventional methods of preparation are used e.g. (i) metallization of the corresponding dis and tris azo dyes which contain in the o-positions to the azo link hydroxyl groups or groups capable of being converted thereto under the conditions of metallization e.g. oxidative coppering; (ii) reacting a metal containing disazo dye wherein K is -B-NHR with a mono, bi or polyfunctional acylating agent optionally in the presence of further compounds containing amino groups; the acyl residue may contain a reactive group and (iii) diazotization of disazo dyes wherein K is B-NH2, coupling and subsequent metallization or when an amino group containing coupling components is used triazolization of the amino group o to the azo link.  The dyes obtained give blue and green dyeings on cotton and regenerated cellulose.
Patent GB-1285559-A (GB)
Title: Improvements in or relating to apparatus suitable for use in the manufacture of shoes
Inventor: BOOT HERBERT WILLIAM
IPC: A43D23/02
Filed: 1968-10-10
Abstract: 1285559 Boots &c BRITISH UNITED SHOE MACHINERY CO Ltd 9 Oct 1969 [10 Oct 1968] 48014/68 Heading A3B In a shoe support, e.g. for a shoe bottom roughing machine, of the type in which the heel end of the shoe S is initially clamped between a hold-down 170 and a presser plate 142 and then side clamps 194 are applied, the hold-down can be moved to an inoperative position leaving the shoe S held by the presser plate 142 and slide clamps 194 to enable an "all round" roughing operation to be performed. When a "toe to breast line" roughing operation is performed the hold-down 170 remains in its operative position opposite the presser plate 142. As described the hold-down 170 and associated mechanism is incorporated in a shoe support of the type described in Specification No. 1,234,404, the presser plate 142 and side clamps 194 operating as described in the aforementioned Specification. The bold-down 170 is formed on one end of a lever 168 which is pivoted to a block 400 by pin 172. The block 400 can slide in guides 402 in a main casting 404. The opposite end of the lever 168 is connected by pin 408 to a toggle mechanism which consists of a pair of links 410 (only one shown) pivoted by pin 418 to a lever 420. The lever 420 is keyed to shaft 422 which carries a second lever 436 connected to the piston rod 440 of a piston and cylinder 442. A pin 416 connecting the links 410 passes through a cut-out 426 in the lever 420 and carries rollers 414 on its ends. When the holddown 170 is in its operative position the toggle mechanism is in its straight position, the pin 416 being located in a recess 428 (Fig. 2) in the cut out 426. When an "all round" roughing operation is to be performed a manually operated selector valve (not shown) is set to an "all round" position which causes piston and cylinder 442 to be operated after the shoe has been clamped in position. This causes the shaft 422 to rotate which initially "breaks" the toggle mechanism 410, 420 to raise the hold-down 170 (Fig. 2). During the movement of the lever the pin 416 moves from recess 428, across the cut-out 426 to recess 430 which locks the toggle mechanism, further movement of the lever 420 thus causing the block 400 to slide rearwardly to a retracted position. At a later stage rollers 414 contact abutments 452 which tends to straighten the toggle mechanism (Fig. 3) so that the hold-down 170 is lowered to its retracted inoperative position. At the end of the machine cycle the hold-down 170 returns to its operative position. When a "toe to breast line" roughing operation is to be performed the selector valve is set to its "toe to breast line" position and the hold-down 170 remains in its operative position. Operation of the selector valve also controls the position at which the roughing tools are raised.

Title: An improved method of filtration
IPC: B01D29/00
Filed: 1965-11-15
Abstract: A fixed upper shell in the form of a rectangular box open at the bottom is spaced above a fixed lower shell in the form of another rectangular box having a filtrate outlet pipe and an open top across which is secured a wire mesh screen.  Filter paper, extending from a roll at one end to a disposal bin at the other, rests on the upper run of an endless wire screen resting in turn on the fixed screen during filtration.  At this time the shells are sealed together by a seal frame telescoping with the upper shell, to which latter liquid to be filtered is supplied.  On clogging of the filter paper the following sequence of operations is initiated and carried through electrically: pressure sensing, cut-off of unfiltered liquid, compressed air blow-through (in filtering direction), seal-frame up, paper advance, seal-frame down, resumption of filtration.

Abstract: 1,072,307. Tiltable revolving chairs. AMERICAN METAL PRODUCTS CO. Nov. 16, 1965, No. 48555/65. Heading A4J. In a tilt mechanism for a swivellable chair, the loading of the tilt controlling spring means can be varied, on swivelling supporting plate 89 about the axis of tubular support post 104 with button 105 depressed. In this position the inner end of the button lies in the path of plate 103, thus preventing spider 100 from being rotated in unison with plate 89, while rod 97 rotates therewith. The spring means consists of compression spring washers 98. Plate 89 is adjusted vertically, with respect to post 104, by swivelling it, with button 111 depressed to hold screw-threaded sleeve 108 against rotation. In another form, button 105 is replaced by a lever (75) and the height adjustment is effected by rotating a ring nut (87).
