[Also in Division B8] A distributer of the type wherein  tobacco in the form of shreds or fragments  is supplied at the feed end (top, as shown) in an inhomogeneous stream and is delivered at the product end 6 in a uniform  stream of predetermined cross-section and comprising also a duct provided with at least one shouldered portion 7 corresponding to a reduction in transverse crosssection and a device, a paddle wheel 14, for accelerating the stream associated with the portion 7, the wheel 14 is sited within the shouldered portion 7. As shown in the Figures, which are cross-sectional views about two vertical planes at right angles, a plurality of shouldered portions 7, 7<SP>1</SP>. . . . 10<SP>1</SP> are each provided with a paddle wheel 14, 14<SP>1</SP> . . . . 20<SP>1</SP>. The wheels of a same pair 14 and 14<SP>1</SP> &c., are rotated at the same speed but in opposite directions, wheels 14, 15 &c., rotating clockwise as viewed. The speed of rotation of each pair below the first pair 14, 14<SP>1</SP> exceeds that of the pair immediately above it by a factor that is somewhat greater than the factor by which the crosssectional area of the distributer is reduced at the corresponding shoulder portion 7, 7<SP>1</SP> &c. The distributer may, for example, be used for feeding a torrefier or for dosing cut tobacco, in which latter case the starting or stopping of either all or some of the wheels 14 . . . . 201 can be controlled by photoelectric or microswitch detection of the presence or absences of tobacco in the duct sections 2, 3 . . . . 6. Mention is also made of a distributer comprising an open passageway, shaping being effected at the sides and the acceleration devices comprising endless belts or cylinders.

Title: Improvements in opening devices for stationary screwing die heads with pivoted die holders
IPC: B23G5/12
Filed: 1924-05-07
Abstract: 215,759. Reinery & Co., Ges. May 8, 1923, [Convention date]. Screwing d i eheads.- In a non- rotary self - opening die - head of the pivoted die - carrier type, the opening lever occupies the same position for several adjustments of the dies, so that it may be tripped by a member acting parallel to the axis of the head. The die-carriers, of which one is shown at b, are adjusted by slots and pins on a rotatable member d having a lug on which is pivoted an eye-bolt e. A screwed rod f, carrying adjusting nuts l, passes through the eye of the bolt and is attached by a forked end and pin q to a link pivoted at k to a lug on the die-head. A set-screw h and lock nut g serves to maintain the alignment of the pivots e, q, k in the various adjusted positions of the dies. Opening is effected by a lever m pivoted at k and engaging the link j by a slot and pin r which permits the lever to assume the same horizontal position throughout the adjustment of the dies. The lever is supported in the cutting position by a stop n pivoted at t and adapted to be rocked by an abutment so as to allow a spring o to actuate the lever.

Abstract: 478,638. Arc converters. ALLGEMEINE ELEKTRICITATS-GES. April 20, 1936, No. 11331. Convention date, April 18, 1935. [Class 39 (i)] Converters 1-4 are connected to a closed gas-circulating system in which the gas resistance of the system, with the exception of the paths between the electrodes, is small compared with the total resistance of these paths and at points where eddying is likely to occur, the cross-section of the pipes is enlarged so that, over the whole working range of gas velocity, the velocity of flow of the gas at the electrodes can be regulated by control of the pressure head at the blower. The gas is circulated by a blower 19 which is connected in the column pipe 31, provided with a cooler 22, and is supplied to the converters through pipes 5-8 tapped off branch pipes 13, 14. To prevent eddies, tapered pipe sections are in serted as shown and the pipes 13, 14 may be tapered. The supply to each converter may be taken from a common point on the pipe 31. The pipes may be used for supporting the converters which may be of the type in which radial and axial gas streams are used. The gas ducts in the electrode as. sembly may be taper. ed as shown in the upper part of Fig. 2. Rotation of the gas in the header 42 may be minimized by a partition 43 and by tapering the header in a direction from the opening 44 to the partition 43 or by widening the supply pipe immediately in front of the opening 44.

The acyclic compounds above are prepared by reacting (CH3)2C=CHCH2CH2C(CH3) =CHCH2X (where X is halogen) (i) with CHRR1CN in the presence of NaNH2 (R and R1 being H or CH3), or (ii) with CHR(CN)COOR11 (R being H or CH3 and R11 being alkyl) to produce (CH3)2C=CHCH2CH2C(CH3)= CHCH2CR(CN)COOR11, followed by hydrolysis and decarboxylation. Cyclization of the acyclic compounds by means of acid catalysts such as H3PO4 or BF3 produces the compounds <FORM:0997935/C2/3> where a double bond is in one of the dotted positions.  The compounds of the invention have odours useful in perfumery.  Geranyl bromide is prepared from PBr3 and geraniol in pyridine.  Geranyl chloride is prepared from PCl3 and linalool in ether.

Abstract: A hardenable composition suitable for impregnating or loading sheet material for shoe stiffeners comprises a hardenable resin and a curing agent which is incorporated in a substance solid at room temperature and which will melt on heating to allow intermixing of the resin and curing agent, e.g. a wax.  In an example, finely-divided diammonium phosphate is mixed with three times its weight of molten hydrogenated castor oil (Opal wax) and the mixture spray dried.  The powder is washed with water to remove any exposed catalyst.  A further example describes a wax/catalyst powder comprising benzoic acid, Opal wax and stearic acid.  The wax catalyst powders may be suspended in an aqueous solution of a urea-formaldehyde precondensate, a phenol-formaldehyde precondensate and rubber latex, and used to saturate flannel (see Group VIII).ALSO:Finely subdivided diammonium phosphate is mixed with three times its weight of hydrogenated castor oil, and spray dried.
