Title: A process for the manufacture of diaryl-dialkyl-ethane derivatives
IPC: C07C37/07
Filed: 1945-08-07
Abstract: 1 : 2 - Di - (p - hydroxyphenyl) - 1 : 2 - dialkyl - ethanes are produced by oxidizing 1 : 2-di-(p-hydroxyphenyl) - 1 : 2 - dialkylethylenes with mild oxidizing agents, e.g. PbO2, FeCl3, Ag2O and lead tetracetate, rearranging the a ,b -dialkyl-stilbenequinones, by treatment with an acid (e.g. a concentrated organic acid or dilute mineral acid) or alkali, into 2 : 3-di-(p-hydroxyphenyl)-butadienes-1 : 3, which are substituted or unsubstituted in the 1 and/or 4 positions, and reducing said butadienes, e.g. by hydrogen iodide in the presence of phosphorus or by catalytic hydrogenation using palladium.  In an example, diethyl-stilboestrol is oxidized to a  : b - diethyl - stilbenequinone which is rearranged into isodiene-oestrol and reduced to 1 : 2-di-(p-hydroxyphenyl)-1 : 2-diethylethane.  The Specification as open to inspection under Sect. 91 comprises also the direct hydrogenation of the a ,b -dialkyl stilbenequinones in the presence of platinum to produce trans-1 : 2-di-(p-hydroxy - phenyl) - 1 : 2-dialkyl - ethylenes, thus making it possible to convert the cis-compounds into the corresponding trans-compounds.

[Class 5 (i)] In a machine for cutting tobacco or other leaf, of the kind in which the leaves are fed by a conveyer 10 towards a cutting aperture A and are compressed into a cheese whilst being so fed, a leaf-container 12 is arranged above the conveyer 10 and oscillating presser-means 22 are arranged to facilitate the supply of leaves to the conveyer and the feed of the leaves by the conveyer. The means 22 comprise spaced curved rods connected by a spindle 17 adjustable in slots 23. The leaves are tamped in the container 12 by L-shaped members 43, 44 connected, as a unit, to a shaft 46 journalled in trunnions 47 carried by a supporting plate 48 which is vertically reciprocated through a linkage 50, 51, 52 by a crank-pin 55 acting on a slotted lever 53 so that the members 43, 44 are raised and then, in virtue of the slot 57, allowed to drop freely on to the leaves. The horizontal parts 44 project through vertical slots in the wall of the container 12, and friction means are provided which act, as the members 43, 44 are rising, to swing the members about the axis of the shaft 46 and withdraw them from the container, and thus allow the introduction of leaf to the container 12 through a side feed aperture. When the members 43, 44 start to descend, they are swung in the opposite direction and fall on to the leaves. The members 43, 44 and presser 22 are actuated from the gearing 30-37. The tamping-means may be duplicated to act on opposite sides of the container 12.

Abstract: 204,406. Jackson, W. J. Mellersh-, (Hartford Rubber Works Co.). June 29, 1922. Chucks.-In apparatus for mounting tyre covers on seating-rings prior to vulcanizing a chuck 1 comprises plates 12, 13 grooved to receive arms 14, 15 of segments 16, 17. The segments 17 have flanges 19 which slide in slots 20 in the segments 16 and form the sealing-groove. Each segment arm 15 carries a roller 22 which enters a spiral groove 23 in a cam plate 24. Rotation of the cam plate 24 is effected by a hand wheel 33 through a gear train 32, 31, 26, 25 unintentional rotation, e.g. due to inertia of the hand wheel when the chuck is rotated, being prevented by a hand-operated detent 51 on a spoke of the wheel which engages a notch 34<1> in a collar 34 keyed to the hub of the chuck plate 13. To accommodate sealing-rings of different widths, the plates 12, 13 are slidably mounted on the shaft 2, and their distance apart is adjusted by a right and left handed screwed member 66 mounted in a collar 68 fast to the shaft. Modifications of the means for locking the cam plate, and for adjusting the distance between the plates, are described.

Title: An improved method of manufacturing wafer biscuits
IPC: A21B5/02
Filed: 1938-07-11
Abstract: Wafers or waffles are produced by applying the raw dough or paste to a sheet of metal foil and then baking the dough together with the foil.  Alternatively, the foil may be placed on the dough which is then baked, or the dough may be baked between two pieces of foil. The foil may be readily stripped off before the wafer is eaten. Wafers thus produced retain their freshness and, when used as the outside layers of wafer confectionery, serve also to keep the confectionery itself fresh.  Wafer baking irons may be used to produce the wafers, the foil being placed on the lower iron to receive the dough poured thereon, or the dough may be poured on the lower iron and the foil placed on the dough, or both upper and lower pieces of foil may be positioned before the irons are closed.
