Rolling - machines. - Relates to a dough-kneading machine comprising two endless bands 4, 18 which can be arranged at right-angles to one another as shown for moulding spherical rolls or short cylinders, or the frame carrying the upper band can be removed and replaced in a position at right-angles to its first position so that the bands are arranged in the same direction as one another and longer cylinders of dough are produced. When the bands are crossed they may be driven intermittently for producing spherical rolls from an oscillating lever 24 by ratchet gearing 42, 43, 44, 45 and 48, 49, 50, one band being moved when the other is at rest; or, when it is desired to produce short cylinders of dough, the lever and ratchet mechanism may be disconnected and the bands driven continuously by chain and belt gearing. The upper rolls are carried upon a frame comprising rods 16 which are supported in open slots in the ends of vertically adjustable rods 8. Provision is made for adjusting the tension of the bands and for pressing the acting portion of the one towards that of the other by means of horizontally and vertically adjustable rollers acting on the lower portion of the band. Flour is supplied to each band as it passes over one of its rollers by means of a brush 71, Fig. 18, rotating in a trough 77 containing flour. The trough is mounted to turn upon the shaft 70 of the brush and is weighted so as to be pressed towards the band. The flour which is picked up from the trough by the brush is projected against the band by an eccentric rod 75 which engages with the bristles of the brush and may be adjusted by rotation so as to engage with the bristles to a greater or less extent. The surplus flour is removed from the band by a second brush 73.

Abstract: 333,553. Naamlooze Vennootschap Mijnbouw-en Cultuurmaatschappij Boeton. Jan. 16, 1929, [Convention date]. Mineral and tar oils, purifying.-High boiling hydrocarbons containing unsaturated compounds are decolorized and converted into low boiling hydrocarbons by treatment at a temperature above 60‹ C., preferably between 70‹ C. and 100‹ C., with concentrated aqueous solutions, liquid at atmospheric temperatures, containing at least 50 per cent of one or more solid hygroscopic chlorides of a heavy metal, and distillation of the resultant oil after removal of the salt solution. The treatment may be carried out in a cracking still, or prior to entry therein. In the latter case, the oil may be neutralized before entering the still. A solution of ferric chloride of specific gravity 1.6 is particularly suitable, but the chlorides of zinc, copper, aluminium, or nickel may be used. In an example 1 litre of crude petroleum of boiling range 150-250‹ C. and containing 60 per cent of unsaturated compounds is treated with 250 cc. of a ferric chloride solution of 1.6 specific gravity; the mixture is agitated for 15 min. at 70-100‹ C. The oil is separated, neutralized, and distilled; 300 cc. of water-white petrol of boiling range 70-150‹ C., 500 cc. of kerosene of boiling range 150-250‹ C., and a residue boiling at 250-350‹ C. are obtained. The latter yields a lubricating oil fraction. A crude petroleum of the same boiling range, but with only 20 per cent of unsaturated constituents when similarly treated vields onlv 100 cc. of petrol, and a smaller fraction boiling over 150‹ C.

Abstract: 1370012 Making electrical connectors HENRY & THOMAS Ltd R A LEGGETT and H F CULLENDER 23 Nov 1971 [23 April 1971] 11205/71 Heading B3A [Also in Division H2]  An electrical connector comprises an elongate body 10 having channels 18 in face 17 each of which receive the middle portion 22 of a metal strip terminal. Each channel extends from the edge of an adjacent face to some point on the face 17 and is formed so that its mouth is narrower than its base, e.g. it may have a T- shaped cross-section. The remainder of this piece is traversed by a channel 20 of uniform width. The portion 23 of the strip is upstanding from the face 17 and the portion 21 lies along the face 14, possibly in a recess 15. The width of the portion 22 precludes movement out of the mouth of the channel whilst the length of the section, and the presence of cranked portions 21, 23 ensures that little or no movement occurs longitudinally of the channel. Ends 12 of reduced height may be provided and may have oval boltholes therein for fixing purposes. In use, Fig. 8 (not shown), two connector blocks are placed face to face so that terminals 21 on one connector respectively touch terminals 21 of the other connector. Connections may be made to portions 23, for example by wirewrapping which may also be the method used to connect together each pair of terminals 21. To facilitate alignment, the portions 21 may be bowed or angled away from one another or the edges may be chamfered (Figs. 9-11). The connectors may be assembled by forming each strip with the portions 22 and 23 collinear and at right angles to the portions 21. This strip may be slid into a channel and the portion 23 bent as shown, e.g. by arranging one die of a press to enter the channel 18, and carrying out the bending against it thereby preventing damage to the channel.
