Title: Process for dyeing or printing cellulose-containing textile materials and solutions and dyestuff preparations therefor
IPC: D06P3/64
Filed: 1952-11-17
Abstract: In the dyeing or printing of cellulose-containing textile materials with metalliferous azo dyestuffs sparingly soluble in water, there is employed a neutral to alkaline dyebath or printing paste comprising (1) a dyestuff containing at least two azo-linkages, of which at least one is present in an ortho : ortho1-dioxy-azo grouping or an ortho-oxy-ortho1-carboxyazo grouping, and capable of forming complex metal compounds sparingly soluble in water; (2) a solid and advantageously aliphatic amine containing at least one amino group separated by two carbon atoms from an HO- group; (3) anions of orthophosphoric acid; and (4) an alkali-resistant compound of copper, nickel or cobalt, advantageously a compound in which the metal is bound to at least one of the aforesaid substances.  Thus the dye-bath or paste may initially contain a dyestuff premetallized with copper, nickel or cobalt, or metallization may be effected in situ.  When a premetallised dyestuff is employed the bath or paste may also contain the amine together with a trialkaliphosphate, or it may contain an ortho-phosphate of the amine, e.g. the neutral phosphate of 1 : 2-di-(b -oxyethylamino)-ethane of the formula <FORM:0732925/IV (c)/1> , together with an alkali hydroxide or excess of the amine.  When a metal-free dyestuff is initially employed the paste may also contain a complex metal compound of the amine, e.g. copper glycocoll, together with a trialkali phosphate; or a trialkali phosphate together with the amine and a compound of copper, e.g. a complex alkali-copper compound of an aliphatic oxycarboxylic acid such as lactic, citric or tartaric acid, e.g. sodium copper tartrate; or a copper phosphate-amine complex of the formula [Cu(HO-CH2-CH2-NH-CH2-CH2-NH -CH2-CH2-OH)]3(PO4)2.  Specified amines are aminoacetic acid and those of the following formul <FORM:0732925/IV (c)/2> (or a mixture thereof with 2-amino-ethanol). The bath or paste may also contain urea, saccharose and dextrin. Dyeings or prints may be after-treated with the reaction product of formaldehyde with cyanamide, dicyandiamide, dicyandiamidine or melamine. Numerous examples are given of the dyeing and printing of cotton.

Abstract: 408,342. Distilling solid carbonaceous materials. FREEMAN, N. H., 7, Baldwin's Gardens, Gray's Inn Road, London. Oct. 18, 1932, No. 29149. [Class 55 (i).] In the extraotion of liquid hydrocarbons from coal, shale, or the like, the material is subjected to progressive stages of heat treatment during its passage through a series of communicating retorts, and the condensates from one stage with, or without volatiles are fed to a preceding or succeeding stage. The ground material is fed from a hopper 12 into a series of retorts A, each of which contains a rotating plate 9 on which the material is propelled by ploughs 10 from the centre to the periphery, from which it falls to the lower surface of the retort, and is guided by ploughs 11 attached to the plate to the central opening 1 of the next retort below. These retorts are heated by gas burners 6 each controlled by a thermostat B so that progressive heating is obtained. The distillates from each of the retorts pass by a pipe 14 into a reflux condenser C from which a portion of the condensate is supplied by a pipe 15 to the preceding retort, and gas by a pipe 16, but both these pipes can be byepassed to deliver oil or gas to a succeeding retort. The gas is led away through a pipe 18 to condenser 19 and storage, and excess of oil from each condenser is passed to storage through pipe 17.

Title: Improvements in or relating to weighing apparatus
IPC: G01G19/00
Filed: 1930-09-30
Abstract: 366,109. Weighing-apparatus. TOLEDO SCALE MANUFACTURING CO., Monroe Street, Toledo, Ohio, U.S.A. Sept. 30, 1930, No. 29269. Convention date, April 21. [Class 143.] In a weighing device whereby, in particular, the moisture in the ingredients of concrete may be allowed for, comprises means for supporting a load containing a plurality of constituents in predetermined ratio (for example, sand and moisture), automatic load counterbalancing and weight indicating mechanism, variable lever mechanism for transmitting force exerted by the load to the counterbalancing mechanism and means for adjusting the lever mechanism in accordance with the percentage of one part of the constituents to cause the indicating mechanism to indicate the weight of the remaining part of the load. Assuming that it is desired to weigh out 500 lbs. of sand of which the moisture content has previously been determined as 10 per cent, for example, by means of the apparatus described in Specification 353,916, the operator rotates a hand-wheel 53 so as to slide a weighing dial 41 along the top of a cabinet 22 until a stationary pointer 58 registers 10 per cent on a percentage chart 59 attached to the dial. An arm 46 on the dial simultaneously slides a member 35 (connected to the dial mechanism by a rod 38) along a beam 25 so as to change the leverage ratios between the fulcrum 26, rod 38 and draw rod 27, the latter rod being connected by a beam 20, rod 19 and a further lever system (not shown) to the weighing hopper into which the moist sand is loaded. In this position of the mechanism a 10 per cent excess of moist sand will be required in the weighing hopper in order to indicate 500 lbs. on the dial and in this way, the moisture is allowed for. The connection between the arm 46 and the member 35 comprises a slotted frame 47 and stud 48, permitting free vertical movement of the beam 25. The beam is normally locked by a spring-operated latch 55 which may be freed by means of a handle.

Title: Improvements in or connected with weft detector or feeler mechanism for looms
IPC: D03D51/34
Filed: 1922-10-27
Abstract: 209,863. Smith, F. L., and Shackleton, G. W. Oct. 27, 1922. Weft-feeler arrangements.-Weft detector devices for weft replenishing mechanism of the type wherein the detectors are carried over an inclined or cam piece 2 as the shuttle box rises and falls to first withdraw the detectors and then allow one of them to enter the shuttle box, as described in Specification 28795/12, are modified so that they can not only be used with a rising and falling box, but also with a shuttle box wherein only one cell is used so that the box is then stationary. The cam piece is mounted upon a rod 4, which is guided through brackets 5 fixed to the shuttle box back and is pivoted to a rod 8 pivoted at 8<b> to an adjustable bracket 9 on the loom framework. The rod 4 therefore rises and falls as the lay moves and the cam piece acts on a runner 12 to withdraw the de tector 13 from the shuttle box, except at the beat up when the detector moves into the box under spring action and in case the weft is exhausted enters through an opening in the bobbin. The detector moreover acts on a spring-controlled catch 14 on a rod 16 so as to move a notch on the catch into position to be engaged by a projection 15 on the rod 4. The rod 16 is consequently lowered and by lever mechanism 17 withdraws an arm 19 from its position supporting a bunter lever 20, which then descends and en. gages a lever S whereby the loom is stopped. If it is desired to use the detector mechanism with a vertically moving shuttle box having two cells 7, 7<a>, the part 8 is detached and the rod 4 is secured by nuts 4<a>, 4b to a bracket 21 on the framework 25.
Patent GB-368313-A (GB)
Title: Improvements in laminated springs for motor vehicles
IPC: F16F1/22
Filed: 1930-09-30
Abstract: 368,313. Laminated springs. SMITH, R. H., O.K. Buildings, Queen Street, Brisbane, Australia: Sept. 30, 1930, No. 29335. Convention date, Sept. 30, 1929. [Class 108 (iii).] In a device for increasing during flexure the pressure between the plates of a laminated vehicle-suspension spring, one or more auxiliary leaves 2 are held in contact by means of clips such as U-bolts, plates, and self-locking nuts with projections formed by making one or more of the spring leaves 1 cuniform at or near their ends. In a modification, the projections are replaced by a rack 7, Fig. 3, on one of the intermediate leaves of the spring coacting with a rack 12 carried on an adjustable extension 9 of the auxiliary leaf 8. A clip 13 holds the racks in engagement, a dust shield 11 may be provided and blocks welded to the leaves, or eyes formed on the ends of the spring plates may form the projections. The Specification as open to inspection under Sect. 91 (3) (a) describes various constructions for achieving the same object. In one construction the projections formed on consecutive leaves register one in the other and an auxiliary leaf 58, Fig. 14 (Cancelled), presses against two such pairs, or a saddle, Fig. 20 (Cancelled), in conjunction with an auxiliary leaf may be provided for each pair of projections. In a second construction a wedge block is inserted in a depression formed on one leaf of the spring. The wedge block is connected to the shortest leaf of the spring by links and the depression bears against the auxiliary spring, the ends of which are carried in U-bolts. In a third construction the wedge-block is replaced by a saddle 11, Fig. 3 (Cancelled), arranged in a depression 8 in one leaf of the spring. Rotary motion is given to the saddle by means of a connecting-rod 13 attached to the saddle and to the axle attachment. Alternatively the saddle may be pivotally carried at the end of one leaf of the spring in which case the saddle bears directly on the auxiliary leaf. In a fourth construction, Fig. 6 (Cancelled), racks on one of the spring leaves 17 and the auxiliary leaf engage a grooved elliptical roller 21. In a fifth construction, Fig. 10 (Cancelled), a bolt 27 is screwed into the doubled end of the leaf 26. A shoulder on the bolt bears against the auxiliary spring and the bolt is rotated by a connecting-rod 32 attached to an arm 30 carried by the bolt and to the axle mounting. In a sixth construction, Fig. 25 (Cancelled), the ends of the auxiliary leaves 85, 91 bear against abutments either carried by, or formed by doubling over, the ends of the spring leaves. A construction in which a secondary auxiliary spring situated above the laminated spring is employed in conjunction with coacting racks is also described. This subject-matter does not appear in the Specification as accepted. Specification 222,323, [Class 108 (iii), Springs &c.], is referred to.

Title: Improvements in or relating to visual warning devices for indicating loss of tensionin bolts
IPC: E21D21/02
Filed: 1962-07-31
Abstract: 950,552. Indicating loss of tension in anchorbolts. W. G. B. McCLEAN. July 31, 1962 [Aug. 22, 1961; Sept. 5, 1961; Dec. 15, 1961], No. 29426/62. Heading F2H. A resilient device, e.g. formed by normallystraight steel strips 13 secured at their ends to a coiled spring 12, is mounted concentrically on a bolt or stud 3 so that, when a nut 7 is tightened on the latter, outward expansion of the device, e.g. bowing of the strips 13, retains an indicator ring 15 until the bolt or stud works loose or loses its load-carrying capacity so that the ring 15 is released and indicates the state of the bolt or stud. As shown the device is applied to an anchor-bolt with a nut 6 and anchoring wedgeshells 4, 5 at one end. If the bolt hole 1 is horizontal so that the ring 15 does not fall on release there may be an ejector spring, Fig. 2 (not shown), between the ring and a washer 8 at the hole mouth. In this case the resilient device consists of steel strips secured at their ends to two spaced washers to form a cage. In another form, Fig. 3, a spring ring 30, in the form of a coil joined at its ends, or a ring of rubber or resilient synthetic material, is held against a washer 21 by a ring member 22 around the bolt shank 3, the spring ring resting on the downwardly and outwardly sloping tops of three radial projections 26 from the periphery of the ring member so that tightening of the ring member 22 towards the washer 21 expands the spring ring 30 out radially adjacent the radial projections 26 to hold an indicator ring 32 by contacting its inner surface. A lack of tension in the bolt allows the ring member to slacken and the expanded portions of the spring to contract so that the indicator ring 32 drops to dangle from a hook-projection 23 from the ring member as a visual indication of the state of the bolt. The ring member is cupped for the retention of a coiled spring 25 between it and the washer. The indicator-and-washer assembly is held between nuts 24 and 31 when the bolt is inserted in the hole 1. Tightening of the nut 24 causes the shank 3 to rotate so that the wedgeshells 4, 5 get a grip in the hole 1. Further tightening shears the nut 31 so that still further turning of the nut 24 draws out the stud 3 to anchor the bolt firmly.

The engine described in Specification 824, 673, with reference to Figs. 4 - 6 thereof, is modified in that the scavenging air or charge trapped in each of two reservoirs 15 before the main scavenging air or charge ports 14 open is subjected to the pressure of the engine exhaust gases via a hose 23 which communicates through a slot 18 with the exhaust duct 13. The end 21 of the hose 23 is mounted in a sleeve 19 which is axially slidable on the exhaust duct so that the distance between the end 21 and the engine exhaust port may be varied. This distance is controlled by an engine speed responsive governor 27 so that an exhaust gas pressure pulse reaches the reservoir as the latter's piston controlled port is reopened, to increase the scavenging effect. The control may alternatively be linked to the engine throttle linkage or manually effected.
