Title: Fluid control device
IPC: B25B23/145
Filed: 1972-01-28
Abstract: 1378311 Nut runners THOR POWER TOOL CO 28 Jan 1972 [29 Jan 1971] 4011/72 Heading B3N [Also in Division F2]  The flow of motive fluid to the motor 11, Fig. 2, of a pneumatic nut setting tool is controlled by a device 10 which comprises a housing 16 having a flow passage 24 extending therethrough between an inlet 17 and an outlet 18. Within the passage 24 are arranged in series three flow control valves 30, 46, 70. The valve 30 comprises a valve member 36 biased by a spring 39 to close the passage 24 but openable manually by a lever 40 as shown. The valve 46 comprises a piston 57 which is axially adjustable by a threaded spindle 58 to preset throttle opening 56 to a value giving the desired stall torque. Valve 70 comprises a normally-open valve member 83 which is forced closed by the upstream pressure when the latter exceeds a predetermined value due to high torque reaction on the spindle (13), Fig. 1 (not shown), of the tool. The valve member 83 is set to close before torque stall occurs, the predetermined pressure value being set by adjusting the loading of spring 89 by screw 96. Once the valve member 83 is closed the pressure in the motor 11 drops rapidly to atmospheric. Thus torque reaction exerted by the tool on the operator is reduced, and the operator cannot apply torque to the work by hand. Subsequent release of lever 40 enables spring 39 to lift valve member 36 against its seat 38 thereby terminating communication with the upstream portion of passage 24, and to lift the upper end of a flat 117 on the valve member above bushing 34 thereby venting the downstream portion of passage 24 to atmosphere whereafter the valve member 83 returns to its open position under the action of spring 89. A small quantity of lubricating oil is delivered from pressurized chamber 12 through a regulator 116 into the passage when the pressure in the latter is atmospheric.

IPC: C09B29/30
Filed: 1925-02-13
Abstract: Azo dyes are produced by coupling diazo compounds with alkyl- or aralkyl-arylsulphaminonaphthol sulphonic acids.  As diazo compounds may be used simple amines, aminoazo compounds, tetrazo compounds, or intermediate compounds from a tetrazo compound and 1 mol. of another component.  The products yield red to blue shades on wool and are faster, particularly to chlorine, and generally more yellowish than the corresponding dyes from arylsulphaminonaphthol sulphonic acids. If the arylsulpho-group contains the o-hydroxy-carboxylic group (as in the salicylsulpho-group) the dyes will dye chromed wool in fast shades; they may then also be used for chrome-printing on cotton. According to examples (1) diazotized o-phenetidine is coupled with 1 - ethylp-toluenesulphamino-8-naphthol-3 : 6-disulphonic acid; (2) the aminoazo compound from aniline- 2 : 5-disulphonic acid and 3-amino-4-cresolethylether is diazotized and coupled with 2-methyl-salicylsulphamino-8-naphthol-6-sulphonic acid. Alkyl-arylsulphaminonaphtholsulphonic acids. -1 - Ethyl-p-toluenesulphamino-8-naphthol-3 : 6-disulphonic acid and 2-methyl-salicylsulphamino-8-naphthol-6-sulphonic acid are prepared by condensing the corresponding alkylaminonaphtholsulphonic acids with p-toluenesulphochloride and salicylsulphochloride respectively.
