Filed: 1926-03-09
Abstract: 248,791. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). March 9, 1925, [Convention date]. alpha-Aroyl-#-naphthols; benzanthrone derivatives; dibenzopyrenequinones.-By treating with acid condensing agents in the presence of a diluent, #- naphthyl esters of aromatic acids are converted into a-aroyl-#-naphthols; the latter by further condensation (ring closure) in absence of a diluent are converted into oxybenzanthrones or dioxydibenzopyrenequinones. The latter are also obtained directly from the #.naphthyl esters when a diluent is not present. According to examples, (1) naphthyl-2 : 6-dibenzoic acid ester is converted into 1 : 5-dibenzoyl-2 : 6-dioxynaphthalene by boiling with aluminium chloride in tetrachlorethane; the product, by heating with sodium-aluminium chloride at 140-150‹ C. yields 1 : 6 - dioxy-3 : 4 : 8 : 9-dibenzopyrene-5 : 10-quinone together with some Bz2 : 4-dioxybenzanthrone; the same dioxydibenzopyrenequinone. is obtained by heating naphthyl-2 : 6-dibenzoic ester with sodium-aluminium chloride while introducing oxygen, and purifying the product with sodium hypochlorite ; it dyes cotton from the vat in violet shades not fast to light or chlorine : (2) #-naphthyl benzoic ester similarly yields 1-benzoyl-2-naphthol and 4-oxybenzanthrone.

Title: Improvements in and relating to tipping-vehicles
IPC: B60P1/14
Filed: 1926-03-09
Abstract: 252,126. Highways Trailer Co., (Assignees of Burton, R. N.). May 15, 1925, [Convention date]. Covers, wagon.-In a wagon having a body 6 which is adapted to tip for discharging the contents, e.g. by rolling on tracks 7 on the underframe, a cover 11 is supported on the vehicle frame independently of the body and in such a manner that it can be raised or lowered whatever the position of the body. In the arrangement shown, the cover is formed of four separate portions hinged to a longitudinal bar 9 which is carried by two A-shaped frames 8 located at the ends of the vehicle. Each cover portion 11 is independently operable by means of links 17, 18 and an operating-lever 14 mounted on a shaft 16, the links 17, 18 in the extreme position forming a toggle so as automatically to lock the cover portion in its raised position 11<a>. The covers on one side are also capable of being raised by the body 6 when the latter tilts to that side. For this purpose the cover portions 11 are convexed upwardly so that they conform in shape approximately to the path followed by the edge of the body in the first part of its tipping movement, and thus no movement of the cover portions takes place until this edge reaches the centre line of the vehicle. The edge then engages the remote cover portions and lifts them to a partially raised position 11<b>. Stops 20 prevent collapse of the unraised cover portions on the opposite side. At their ends the covers are formed with depending flanges 13, the inner vertical edges 19 of which abut against each other so that, when the cover is in its normal closed position, the separate portions hang in a balanced position on the bar 9.

Abstract: 661,763. Rotary conveyers. ETCHELLS & SON, Ltd., D., and ETCHELLS. W. K. March 7, 1950. [March 11, 1949] No. 6649/49. Class 78 (i). [Also in Group XII] Rod-like articles are fed through a furnace by locating them in axially extending grooves in the periphery of a freely mounted drum around which an endless chain or band is tensioned so as to hold the articles in the grooves, and driving the chain or band whereby the drum and articles are driven, the articles acting as a driving connection between the chain or band and the drum. A carriage 34 runs on rails 35 towards and away from a furnace 26. A fixed horizontal shaft 8 on the carriage supports a drum 7 for free rotation. Rods I pass down a shoot 2 and are fed by a wheel 3, co-operating with a guide 5, into the grooves 6 of the drum 7. Wheel 3 is mounted on a shaft 4 which is driven by an endless chain 9 passing over a sprocket 10 on shaft 4, around the succession of articles in the peripheral grooves of the drum, and over further sprockets 11, 14, 15 and 15x. Sprocket 11 is pressed against the drum by being mounted on a counterweighted lever 12, while sprocket 15 is urged upwardly by a similar weighted lever to tension the chain. The wheel 3 is pressed against the drum by means of an arm 16 on which it is mounted, the arm being pivoted at 17 and urged anticlockwise by a compression spring 18. The chain 9 is driven by a motor 33 through the sprocket 14. This motor 33, through an eccentric and link system 37, reciprocates a boss supporting a radial arm 27, axially along the shaft 8. Adjustable brackets 28, 29 position the arm 27 in a fixed radial position. A stepped pusher 23 mounted for axial adjustment on the end of arm 27 engages the ends of the rods 1 remote from the furnace during each reciprocation of the arm and causes them to extend forwardly in steps to a fully extended position as they move around with the drum 7. This pushes the forward ends into an arcuate slot in the front wall 25 of the furnace 26, which is cut so as to conform to the path of the articles between the feed wheel 3 and the lowest part of the drum, where the slot is cut vertically downwards for the articles to drop out into a shoot 30.
