Title: Anthraquinone dyestuffs
IPC: C09B5/24
Filed: 1958-03-12
Abstract: 1:2:3:4- Tetrachloro-5:8- dimethoxy-anthraquinone is made by methylating 1:2:3:4-tetrachloro-5:8-dihydroxy-anthraquinone with methyl p-toluene sulphonate.ALSO:The invention comprises dyestuffs of the formula:-  <FORM:0879240/IV(c)/1> where A is hydrogen, hydroxy or amino, X is a carbon or hetero atom, Y is an organic radical necessary for the formation of a 5- or 6-membered ring including X and the carbon and nitrogen atom, which ring may be substituted and Z is hydrogen or a heterocyclic nucleus derived from an amine of the formula:-  <FORM:0879240/IV(c)/2> and wherein the ring I may be further substituted, and the alkylation products of said dyestuffs. The dyes are made by reacting at an elevated temperature a 2 : 3-dicyananthraquinone which may be further substituted in the ring I of the anthraquinone radical, or an isoindolenine obtainable by treating thio 2 : 3-dicyananthrawith an acid, an alcoholate, an alkali metal hydroxide, alkali metal sulphide, ammonia or an amine, with an amine or amines of the formula shown above.  The dyestuffs may be subsequently alkylated.  The dyestuffs are used as pigments or vat dyestuffs.  Specification 773,212 is referred to.

IPC: B62D25/18
Filed: 1923-03-23
Abstract: 214,804. Anderson, C. March 23, 1923. Lateral-splash guards are mounted on the wheel hub by a bearing 5, the outer ring of which has a universal-joint and telescopic-tube connection 1, 4 with the ordinary mud-guard 2, and supports a socket 9 accommodating a rod 12 carrying the guard 21. When resilient buffers 18 on pivoted hubs 20 are struck by an obstacle the rod 12 is rocked on its axis and feathers 13 become disengaged from notched stoppers 11 in the socket 9 and enter featherways 10, whereupon the rod and guard are moved upwardly by spring 14. The guard 21 of chain mail is stiffened by a wire 22 threaded through the links and is adjustably mounted on the rod 12 by a, bolt 16 and slot 17. In a modification the guard is restrained against rotation by a post loosely engaging a slot in a bracket attached to the vehicle. In a further modification for use with front wheels the socket is held in an eye-bolt, mounted on a non- rotating member passing through the hub cap and attached to the stub axle.

Abstract: 1,012,767. Shoe sole moulding machines. A. B. SVENSKA SKOLŠSTFABRIKEN. March 6, 1963, No. 8929/63. Heading B5A. A machine for vulcanizing rubber soles to shoes comprises two pairs of lasts 15, each for accommodating a shoe and a rubber sole placed thereon, two vulcanizing stations each with one pressure applying member 18 movable into application with the underside of the sole, and two pairs of mould elements 16, 17 movable into application with the side edges of the soles, one pair of elements 16 being stationary and the other pair of elements 17 movable, last carriages 14 for supporting the lasts 15 movable between a station in which the shoes and soles are mounted on the lasts and the vulcanizing stations, two turntables 13 for conveying the last carriages with the lasts thereon between the mounting and vulcanizing stations each being provided with two slots 21 (Fig. 1, not shown) for receiving the last carriages and having a common mechanism for simultaneously rotating them, a means 36, 49 connected to each turntable for moving a last carriage between the station to which it has been brought and the vulcanizing station, means for simultaneously moving the movable elements 17 and the last carriage towards the respective stationary mould elements 16, and means 68, 69 (Fig. 5) in the vulcanizing station for automatically adapting the height of the last carriage to the thickness of the shoe material. The turntable is rotated through 180 degrees by a rock mechanism until slots 21 line up with similar slots at the vulcanizing station. The first pair of lasts are then moved off the turntable into the operative position by the air-operated movable sleeve 36 which carries a fork-shaped element 49 to engage with a projection 22 on the underside of the last carriage 14. In the operative position the movable elements 17 are then moved towards the last 15 by a cylinder 52 and simultaneously an element 59 mounted on and below mould element 17 on a guide rod 54 presses against the carriage 14 thus moving the last and element 17 into engagement with the mould element 16. The pressure applying member 18 is then moved into position. To adjust for different sole thicknesses the last 15 is mounted upon a vertically movable plate 69 (Fig. 5) in turn mounted upon a horizontally slidable plate 68, both being attached to a fixed plate 72. The plate 68 which has a wedge-shaped portion 70 is adapted to be moved against a downward projection 71 on the underside of plate 69 by a spring-loaded piston 73. The last is lowered by moving plate 69 back to its original position by a crank 81. On completion of the vulcanizing process the mould element 17 and element 59 are retracted, the latter re-aligning the last carriage with a slot in the turntable 13 so that the last carriage may be retracted from the machine. The turntable is then rotated through 180 degrees and a new cycle commenced. The machine may be controlled by a timer 19 activating a series of limit switches.
