Title: New anthraquinone dyestuffs containing aminotriazinylamino groups and process for their manufacture
IPC: C09B1/58
Filed: 1961-12-01
Abstract: The invention comprises anthraquinone dyes which are free from acid groups imparting solubility in water and of which the anthraquinone residue consists of not more than four fused rings and contains a 2,4-diamino-6-phenyl-1,3,5-triazine residue bound to the anthraquinone residue through one of the amino groups and of which the other amino group is unsubstituted or substituted by an alkyl or cycloalkyl residue or forms part of a heterocyclic ring, the said alkyl residues being substituted or unsubstituted. The dyes are prepared by condensing in either order of succession equimolar amounts of an aminoanthraquinone, a 6-phenyl-2,4-dihalotriazine and a mono- or dialkyl- or -cycloalkyl-amine or a heterocyclic amine.  The dyes may be used as vat dyes, but are preferably used as dispersion dyes to colour synthetic fibres, such as cellulose esters, polyamides, polyacrylonitrile, polyvinyl chloride, and in particular aromatic polyesters, in yellow and red shades.  The dyes may also be applied by the thermofixation method.  In an example 2-phenyl-4,6-dichlorotriazine is condensed successively with 1-amino-4-benzoylaminoanthraquinone and mono- or di-methylamine. Further examples are given.

Abstract: 1,148,579. Extruding. OLIN MATHIESON CHEMICAL CORP. 10 Oct., 1966, No. 45123/66. Heading B3P. A hot metal extruded product issuing from an extrusion press 26 is immediately quenched in a chamber 60. The product which may be of circular or other section and made from a billet of non-ferrous alloy, passes directly from the extrusion die 28 on to a run-out table 30 formed by a frame 34, 36 supporting a slab or slabs of graphite 52 provided with large openings (53), Fig. 4 (not shown). The table is pivoted at 40 to a coolant tank 12 and its other end is adjustable in height by screws 44. The frame 34, 36 also supports a hood 60 with end walls 67. Hood 60 carries pipes such as 74, 76, 78, 80 with control valves 82 and pressure gauges 84, for supplying the coolant, which is preferably water, to spray nozzles such as (75), (77), (79), (81), Fig. 3 (not shown). The coolant is supplied at high pressure such as by a pump, and is sprayed on to all parts of the periphery of the product; the control valves 82 enable the spray to be regulated to suit the cross-section of the product. Baffle plates (86), Fig. 3 (not shown), are provided within the hood to guide the extruded product and reduce escape of the coolant. The extreme outer nozzles are also angled to provide an inwardly directed curtain of water which also reduces splash. The open ends of the hood may also have curtains of resilient material. A further spray assembly 100 is mounted on a wheeled carriage 110 movable with variable speed along rails 116 by a fluid pressure motor 120 controlled by a timer 132. When the billet has been extruded and hence movement of the extruded product has ceased, a limit switch 138 is actuated by the press ram whereby the motor 120 is operated to move the spray assembly 100 towards the press. During this period the discard is sheared, and the product is finally withdrawn forwardly through the quenching chamber. Alternatively the entire hood 60 may be mounted on wheels for movement towards and away from the press.

Title: Test arrangement for battery-powered alarm clocks
IPC: C08G69/42
Filed: 1966-10-11
Abstract: 1,102,009. Alarm clocks. GENERAL TIME CORPORATION. Oct. 11, 1966 [Oct. 12, 1965], No.45448/66. Heading G3T. A battery operated alarm clock comprises an alarm switch 16 for closing an alarm circuit incorporating an alarm device 20, a manual operator 30 movable between alarm-off and alarmon positions and a test circuit including a test switch 40 for connecting the battery 15 to the alarm device for test purposes, the test switch being coupled to the manual operator. When the operator 30 is moved from its alarm-off position to its alarm-on position it momentarily moves through a test position in which contacts 41, 42 connect the alarm device 20 and a parallel resistor 43 to the battery 15 so that if the battery has sufficient power the alarm momentarily sounds. Subsequently, when the alarm switch 16 is mechanically operated by the clock movement 11, the alarm is certain to sound since, in the alarm-on position, contacts 26, 27 are made whilst the contacts 41, 42 are broken so that the load on the battery is less than the load in the test position. In a second embodiment with the operator in the test position, the alarm device is connected in series with a resistor to the battery so that if the battery voltage is sufficient to operate the alarm in the test position it will also operate the alarm when the operator is moved to the alarm-on position and the resistor is no longer in the circuit. A modification is described (Fig. 3) in which mechanical means and not an electrical switch are included for enabling and disabling the alarm. When cams 101, 102 on an hour wheel 91 and an index wheel 95 engage, the end 112 of an alarm trip lever 110 is moved upwardly so that the lever is released from a stop pin 115. The lever, which is biased by a spring 113, therefore rotates so that its lug 124 causes contacts 121, 122 mounted on an insulator 123 to touch, thereby connecting the alarm device 60a to the battery 55a. The alarm is turned off by pushing inwardly a plunger 31a so that a cam surface 130 of the plunger engages a surface 131 of the lever to rotate the lug 124 away from the contacts 121, 122. Between the outer or alarm-on position and the inner or alarm-off position, is a test position of the plunger in which a fixed spring contact 82a touches a collar 81a of the plunger to connect the alarm device and a resistor 83a to the battery.
