Title: Process for the preparation of new condensation products of naphthoquinoneimine series and the dyeing of cellulose ester fibres, synthetic polyamide fibres and polyurethane fibres thereby
IPC: C09B43/11
Filed: 1949-03-07
Abstract: The invention comprises the manufacture of dyestuffs by condensing naphthoquinoneimines of the general formula <FORM:0670969/IV (c)/1> (wherein X represents hydrogen or halogen and Y represents NH or O) with an approximately equimolecular quantity of an aromatic aminoazo compound free from sulphonic acid groups, the dyestuffs so obtainable, and the dyeing and printing of cellulose ester fibres and synthetic polyamide and polyurethane fibres therewith. The condensation is preferably effected at a temperature of about 60 DEG C. or above, in the presence of a solvent or diluent indifferent to the reactants, and advantageously in the presence of a condensation accelerator (e.g. boric acid, copper or its salts, or sodium acetate).  In the case of starting materials free from halogen, the aminoazo compound condenses with the imino group, and the reaction generally takes the same course when halogen is present if it is effected in glacial acetic acid.  If, however, the reaction medium in the second case is diluted with water or alcohol, or a rather alkaline catalyst is used, some reaction takes place with the halogen atom, and also part of the imino groups may be hydrolysed, the product usually being a mixture.  Dyeing with the products is effected from aqueous solution or dispersion, preferably at about 60-85 DEG  C., and yields dischargeable green, olive, brown and grey tints.  Examples describe the condensation of 5-amino-8-hydroxy-1 : 4-naphthoquinoneimine-(1) and its 3 : 7 - dibromo derivative with 4 - aminoazobenzene, 41-amino-4-nitroazobenzene, 41-amino-4 - (N - ethyl - N - b  - hydroxyethyl) - aminoazobenzene, 4 - aminoazotoluene and 4 - amino - 21 - hydroxy - 51 - methylazobenzene, and of 3 : 7 - dibromo - 5 : 8 - dihydroxy - 1 : 4 - naphthoquinoneimine-(1) with the first three of these aminoazo compounds.  In a further example, the first of the foregoing products is milled with the sodium salt of a fatty alcohol sulphonate and sodium sulphate and dispersed in water with the further aid of turkey red oil, and cellulose acetate is dyed from the dispersion in pure green shades.  A table gives the properties of further dyestuffs.  Specifications 20997/99, [Class 2], 451,815, 606,008, 613,076 and 629,706 and U.S.A.  Specification 2,135,366 are referred to.

Title: Improvements in and relating to automatic brakes, more particularly applicable to trailer vehicles
IPC: B60T7/20
Filed: 1919-01-23
Abstract: 141,817. Barningham, V., and Ashby, S. G. Jan. 23, 1919. Actuated of applied by relaxation of pull; locking by frictional detents.-The brake-operating mechanism of a trailer vehicle is connected bv flexible means to the draw-bar so that relaxation of the connexion cause the brakes to be applied. and means are provided whereby the brakes are also applied upon backward movement of the vehicle irrespective of the slackening of the drawbar connexion. The brake comprises shoes acting externally or, as shown, internally upon a drum 1 carried by the road wheel, the brake shoes 5 and operating-lever 13 being carried by an arm 8 capable of rotation upon a fixed axle 9 within limits set by stops 10 co-acting with a projection 12 on the arm. A spring 18 anchored to a fixed arm 19 acts on the free end of the lever 13 and applies the brake shoes to the drum whenever a cable 14 connected to the draw-bar becomes slack. To ensure the application of the brake in the event of the trailer commencing to drag the tractor downhill, the following means are provided. The drum 1 has ratchet teeth 20 engaging similar teeth 21 on a sleeve 22 which is pressed outward by a spring 23. The sleeve 22 has a pin 26 engaging a slot 25 in a second sleeve 27 which has a pin 30, Fig. 3, engaging a cam-slot 31 in a third sleeve 28 keyed to the axle 9. The sleeve 27 has lugs 32 engaging slots 33 formed in a ring on the arm 8. As the road wheel rotates backwards, the sleeves 22, 27 and the arm 8 are carried with it, clockwise in Fig. 1, so that relative movement occurs between the arm 8 and lever 13, and the blocks are applied to the drum. At this moment, the pin 30 reaches the end of the slot 31, the inclined part of which effects an axial movement of the sleeves 22, 27 to withdraw the teeth 21 from engagement with the teeth 20. This prevents breakage of the teeth when the projection 12 on the arm 8, which continues to be carried round by the brake blocks, encounters the stop 10, at which moment the braking action commences. The brake may be released in this position by pulling on the cable 14. To render the brakes inoperative when it is desired to move the trailer freely, tension is applied to the cable 14 to bring the end of the lever 13 into engagement with a projection 16 on the arm 8, further tension on the cable causing the arm to move in a clockwise direction and effect the withdrawal of the teeth 21 from the teeth 20. Upon release of the tension on the cable, the spring 18 restores the parts to their normal position.

IPC: A63B49/04
Filed: 1928-01-24
Abstract: 310,350. Claremont, C. A. Jan. 24, 1928. Rackets; handles.-A section of the frame of a lawn tennis or like racket, disposed at the end remote from the handle, is rendered heavier than that of sections on either side of it by an amount predetermined to move the " dull zone " nearer to that end of the frame. The magnitude of the weight necessary to eliminate the " dull zone " is determined by clamping a racket by the handle with the frame horizontal, suspending a weight from the outer end of the frame, noting the rebound of a ball dropped at various points along the longitudinal axis, and repeating the process with weights of various magnitures. The frame may be given the required weighting by forming the end part b, Fig. 1, of rectangular cross-section instead of the usual hexagonal. In addition strips of metal or heavy wood c may be screwed to the frame. In a modification, the weight comprises two weights e, Fig. 5, screwed together through a hole in a metal frame d, and serving if necessary to position thin lead discs e<3>. When applied to a wooden frame, the discs are secured to a pair of metal brackets projecting inwardly from the frame. The balance of the racket may be adjusted by traversing a weight g<4>, Fig. 8, along the interior of the handle by means of a screw g<2> rotatable by a crank g<3>. The weight is held in adjusted position by set screws g<9>, that also serve to prevent rotation of the weight during adjustment. The position of the weight may be observed through a sight opening formed in the handle. A racket having a wooden handle, Fig. 12, may be provided with a balance weight h<4> clamped between a cork plug h<5> and a wooden plunger h<1>. Alternatively, a weight may be freely slidable within a recess in the handle and be retained in any desired position by a setscrew passing through one of a series of tapped holes in the handle.
