Title: Improvements relating to centrifugal governors
IPC: G05D13/10
Filed: 1948-08-11
Abstract: 639,517. Centrifugal governors. WEYBURN ENGINEERING CO., Ltd., and BLACK, J. B. Aug. 11, 1948, No. 21176. [Class 57] A centrifugal governor comprises rotating weights loaded by a compression spring 20 consisting of a helical coil of approximately constant diameter whose pitch progressively increases from a negligible value at least at one end, and means are provided for adjusting the loading of the spring and hence its stiffness by reducing the number of effective coils. The weights are pivoted on a bracket 13 keyed to a driving shaft 11 and have toe pieces 16 adapted to move a governor rod 18 through a thrust bearing 17. The rod 18 bears against a roller 23 which is connected by a clevis 25 to an abutment 26 for one end of the governor spring. The other end of the spring bears against a second abutment 27 slidably guided in a casing 19 and adapted to be moved by a speed control lever 32 through a push rod 28. An adjustable stop 33 determines the maximum speed setting. The spindle of the roller 23 is carried by a pack 22 secured to a shaft 21 which extends through the casing and carries at one end an arm 24 and at the other end an arm 41 connected to the engine throttle or similar control. The pack 22 is also connected through a rod 38 to the piston 36 of a dashpot 35 for steadying the action of the governor. When the lever 32 is moved to the left for idling speeds or starting there is preferably a clearance provided in the mechanism which enables the weights to actuate the shaft 21 without restraint by the spring. For providing a positive setting of the engine throttle &c. at idling speeds or starting the lever 32 has a flat 34 adapted to contact and positively move the lever 24. In a second embodiment the spring 20 is housed in a casing which is mounted alongside the casing 10 housing the governor weights and acts on the governor rod through a lever on an adjustable fulcrum which is used to vary the loading of the spring.

Title: Lock-out means for electric contactors and the like electric circuit-breaking devices
IPC: H01H50/32
Filed: 1943-12-17
Abstract: 571,569. Electromagnetic switches. CLARKE, R., and LAURENCE SCOTT, & ELECTROMOTORS, Ltd. Dec. 17, 1943, No. 21223. Class 38 (v)] A spring-pressed pivoted latch 19, prevents the armature 3 of a contactor from closing under shock or vibration while the contactor is de-energized. On energization of the magnet, flux first builds up in a secondary magnetic circuit 20, 19, to cause the latch 19 to move about a pivot 8 into the position shown freeing the armature 3 so that this then moves to the right into the position shown. This movement operates the contacts and also short-circuits the secondary magnetic circuit so that the latch 19 then falls on to a stop 61 and is ready to assume its original latching position immediately the magnet is deenergized. Specification 547,362 is referred to.

Title: Improvements in or relating to stretchable yarns and fabrics
IPC: D02G1/02
Filed: 1955-07-25
Abstract: 781,030. Knitting. GROVE SILK CO. July 25, 1955 [Dec. 31, 1954], No. 21395/55. Class 74 (2). [Also in Group IX] A fabric is knitted from yarn which is in a " non-lively " condition and possesses a potential twist at least a part of which can be activated by heating in a humid atmosphere to cause the fabric to contract but render it stretchable to its knitted dimensions. The yarn, of stretched microcrystalline polymer, e.g. nylon or polyester, is prepared by successive treatments of presetting, twisting, " twistsetting " by a treatment less rigorous than the presetting, removing twist in the " twist-set " yarn until the " non-lively " condition is obtained. The amount of twist removed depends on the difference between the presetting and " twist-setting" temperatures and such removal may be effected by untwisting single ends or plying yarns with twist opposed to the first twist. According to numerous examples, mono- or multi-filament yarns of 10-70 denier are preset at temperatures of 200-265‹ F. by (saturated) steam under pressure of 25 lb. per sq. in. for a period of 20 minutes without tensioning, e.g. the yarns are wound on tubes having collapsible corrugated coverings or by difference of the yarn speeds at entering and leaving the presetting region; twisted to 30- 100 turns per inch; " twist-set " at 140- 240‹ F.; untwisted by 10-14 turns per inch. The spooled yarns may require to be stored for 4-24 hours for the full effects of the process to develop. " Set-releasing " treatment, the difference between the conditions of which and the conditions of " twist setting " determine the amount of released twist, applied to a fabric may be immersion in hot (180‹ F.) or boiling water for 1-10 minutes after a brief subjection to wet atmospheric steam for convenience to avoid snarling. If stockings are knitted and seamed before the releasing treatment, they are immersed in a dye bath at 160‹ F. or loosely boarded and placed in a chamber with steam at 240‹ F. for one minute: unseamed stockings may be similarly treated with steam. Alternate courses or bands may be knitted with yarns which have been originally twisted in opposite directions.

Title: Improvements in or relating to the art of fabric printing
IPC: D06P1/673
Filed: 1947-08-07
Abstract: Colloidal clay (bentonite) is used as the sole thickener in textile printing pastes incorporating colouring matters or components thereof, for use with screens or roller printing machines.  The clay preferably forms 10-20 per cent by weight of the whole printing paste and is milled or pasted up with water, with or without the application of heat.  Flocculation is prevented by the incorporation of mild alkaline materials, glycerol or mineral oils such as cylinder or turbine oil.  In the case of vat colours, this function is performed by the alkalis normally present in such pastes.  Additions are, however, unnecessary if the paste does not contain any substance likely to cause flocculation, such as acids or concentrated alkalis. Examples show: (1) a vat colour printing paste; (2) an alternative paste for vat colours; (3) a paste for the production of azo colours on the fibre; (4) printing with a leuco-ester of a vat dyestuff; (5) printing on viscose, cuprammonium or other cellulosic fibre with acid and direct dyestuffs.

Title: A process of dyeing and printing of textile goods and other materials adapted to be impregnated
IPC: D06P5/15
Filed: 1923-08-31
Abstract: Goods made of any fibre, cotton, wool, silk, mixed fibres &c., are dyed or printed with the water-soluble esterlike derivatives of leuco vat-dyes described in Specification 186,057, and the colours developed by action of an acidified chromate solution, or, especially in the case of thioindigo, by exposure to light; the leuco-ester and the chromate may be dyed or printed together on the material and the latter passed through an acid bath; nitrosamine red dyestuffs may be printed and developed simultaneously.  Reserve effects are obtained by printing the impregnated goods with thickened hydrosulphite and then passing them through an acid bath for white reserves, or steaming and passing through an acid bath if a vat-dyestuff has been added to the hydrosulphite for a coloured reserve.  Discharge effects are obtained by printing coloured grounds with a leuco-ester salt and hydrosulphite, steaming, and then oxidizing to develop the unchanged leuco-ester salt; for example, a rongalite discharge-salt W discharge mixed with dihydro-indigo ester salt is printed on a thioindigo or diamine dyestuff ground, steamed, and the indigo developed in a warm acidified chromate bath.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of oxidizing agents in general in the above processes and mentions ferric chloride.  This subject-matter does not appear in the Specification as accepted.
