Patent GB-646832-A (GB)
Title: Treatment of cellulose esters and ethers with naphthopyridine derivatives to inhibit gas fading
IPC: D06P1/642
Filed: 1948-08-13
Abstract: Naphthopyridines having the general formula <FORM:0646832/IV (b)/1> or <FORM:0646832/IV (b)/2> wherein X and Y are hydrogen, alkyl, halogen, nitro or cyano, are prepared by reacting 1- or 2-naphthylamine which may be substituted with X and Y, with epichlorhydrin in solution in butyl, amyl or a higher alcohol at the reflux temperature.  The following naphthopyridines are specified, viz, 3-hydroxytetrahydro-5-6-naphthopyridine substituted by 8-iodo-, 12-iodo-, 8-chloro-, 11-chloro-, 12-chloro-, 8,12-dichloro-, 8-bromo-, 9-bromo-, 12-bromo-, 10-ethyl-, 8-cyano-, 9-cyano-, 12-cyano-, 8-nitro-, 12-nitro-, or 8,9-dinitrogroups; 5-hydroxytetrahydro-2,3-naphtho-pyridine substituted by 9,12-dichloro-, 8-bromo-, 8-methyl-, 10-ethyl-, 11-cyano- or 9-nitro-groups; and the corresponding unsubstituted compounds.ALSO:The resistance of dyeings on cellulose ester or ether fibres to acid fading is enhanced by applying before, during or after dyeing, an aqueous dispersion of a naphthopyridine free from groups inducing solubility in water and having the formula <FORM:0646832/IV (c)/1> or <FORM:0646832/IV (c)/2> wherein X and Y are hydrogen, alkyl, halogen, nitro or cyano. Many such compounds are specified. In an example, cellulose acetate silk is dyed in an aqueous dispersion of 3-hydroxytetrahydro - 5,6 - naphthopyridine and 1-methylamino - 4 - ethylamino anthraquinone.  In a second example, the procedure is as above but 3-hydroxytetrahydro-8-chloro-5,6-naphthopyridine is used as the anti-acid fader.  Another example is given in which cellulose acetate silk which has been dyed with 1,4-di-(monomethylamino)-anthraquinone is treated with an aqueous dispersion of 5-hydroxytetrahydro-2,3-naphthopyridine.  The process is particularly useful with aminoanthraquinone dyes and certain azo dyes, several of which are specified.
Patent GB-401447-A (GB)
Title: Improvements in power transmission clutches
IPC: F16D23/06
Filed: 1932-07-29
Abstract: 401,447. Claw clutches ; facilitating change of speed. JENKINS, H. G., Leigh Vicarage, Sherborne, Dorset. July 29, 1932, No. 21457. [Class 80 (ii).] In a claw clutch, particularly for use in conjunction with the tail shaft 2 of a motorvehicle gear-box, pawls 24 pivotally mounted at one end 24a on the driving member 3, carried by the shaft 2, coact with recesses 28 in a member 20, journaled on the member 3 and provided with a conical surface 21 adapted to engage frictionally with a conical surface 22 on the driven member 6 during the clutchengaging movement of the latter, in such a way that, when the speeds of the members 3, 6 differ, the pawls tilt relative to the shaft axis so as to engage steps 29 formed in the recesses and thus prevent clutch engagement, whilst, on the occurrence of synchronism, the pawls return into parallel relation with the shaft axis and enter slots 26, thus permitting clutch engagement. The recesses are convered by plates 35. The member 20 is urged towards the member 6 by springs 27, such movement being limited by projections 30 on the pawls cooperating with the walls of the recesses. Portions 32 of the pawls are in sliding and rocking engagement with portions 25 of the recesses 28. The movable member 6, splined on its shaft 7, is controlled by a fork 15 which is coupled to the main clutch pedal 18 by a rod 40 and a manually-controlled pivoted latch 47. A spring 36 tends to move the member 6 towards the member 3. Thus, with the latch 47 in effective position, the claw clutch is disengaged simultaneously with the main clutch and, on release of the pedal 18, is re-engaged by the action of the spring when synchronism occurs. By moving the latch 47 into ineffective position by Bowden mechanism 50, the connection between the fork 15 and the pedal 18 is disestablished. Specification 331,346, [Class 80 (ii), Gearing, Variable-speed &c.], is referred to.

The cross-section of the end portions of each of the ducts 1 and 2, at right angles to the pivotal axis, is bounded at least in part by arcs of a circle, the diameter of one end portion being just less than that of the other end portion. The driving means is hydraulically operated and is such that the time spent by the duct 2 in moving between its two positions is small relative to the time it spends in each position (at least 1:4) and damping means may be provided. Outlet ducts 3 provide communication between the pivotal duct and the pressure compartments, the sides of the ends 8, 9 of the outlet ducts being 1-2 mm. longer than those of the corresponding sides of the outlet duct. The hydraulic driving means has fluid supplied from a reservoir via a valve operated by electronic timing to a piston and cylinder, which drives the duct 2.

Divided out of 765,941 [Group XIII], Class 75(1) ' An ignition and safety control system for a gas burner, e.g. for supplying heated air to the drying drum of a household clothes dryer comprises an electrically operated master valve 135 in series with an electrically operated main valve 136 in the gas supply line to a main burner (not shown), a pilot burner 137 located beside the main burner and connected to the gas supply line between the two electrically operated valves and a flame detector switch 160 adapted to energize the electrically operated main valve 136 to open position in response to a flame at the pilot burner 137. At starting the coil 140 of the master valve 135 is energized to open the valve and supply gas to the pilot burner 137, through contacts 171, 172 of a time switch 170 comprising a warp element heated by a coil 184 disposed in a metal sheath 184b and energized through the cold contact 161 of the flame detector switch 160. 'The pilot burner is ignited by a glow coil 139 energized by a transformer 138 energized through the contacts 171, 172 of the time switch 170 and also through the cold contact 161 of the flame detector switch 160. If ignition is effected the movable arm of the flame detector switch 160 moves over to the hot contact 162 to de-energize the ignition transformer 138 and the heating coil 184 of the time switch 170 and to energize the coil 163 of the main valve 136 to open the valve. The main burner is then ignited by the pilot burner. If, however, ignition of the pilot burner fails the contacts 171, 172 of the time switch open after a predetermined time to close the master valve 135 and to deenergize the ignition transformer 138. An adjustable thermostat 173 in the circuit to the main valve 136 turns the main burner on and off during normal operation to control the temperature within the drying drum. A safety bi-metal switch 175 deenergizes the burner ignition and control system when the temperature of the drying drum is substantially higher than that at which the adjustable thermostat 173 opens. The drying drum is rotated by a motor 14 and the duration of each drying operation is determined by a timer motor 183 which opens first a switch 181 to deenergize the burner ignition and control system and later a switch 182 to de-energize the motor 14 rotating the drum and the time motor 183. A switch 61 operated by opening the door of the drier de-energizes the motor 14 rotating the drum, the timer motor 183 and 'the main valve 136 and energizes a lamp 131. In a modified system the master valve 135 is independent of the safety switch 175 and the switch 181 of the timer motor.
