Title: A device for turning flat cigarettes and similarly shaped articles right side up when packing same
IPC: B65B19/06
Filed: 1933-08-31
Abstract: 406,932. Packeting cigarettes. UNITED CIGARETTE MACHINE CO. AKT.-GES., 48, Zwickauer Strasse, Dresden, Germany. Aug. 31, 1933, No. 24192. Convention date, Jan. 7. [Class 94 (i).] In a device for ensuring the correct position of cigarettes and similar articles when being packed, the cigarettes are fed on a conveyer 1 past a disc 4 rotating on an axis 5 and carrying a number of pins 7 mounted for rotation about axes parallel to the axis 5. Each pin carries a disc 8 on which is eccentrically mounted a pin 9. The disc 4 is rotated at such a speed that it rotates through a distance equal to that between two adjacent pins 7 while the conveyer is moving the distance of one link. When the pins 9 are disposed in position a in the same circle as that occupied by the pins 7, they pass between the ends of the cigarettes on the conveyer without touching them, as shown in Fig. 3. The pins are normally set in this position by a lever 15, which contacts with a lug 11 arranged on the farther end of each shaft. If, however, a cigarette occupies an incorrect position on the conveyer, the seam being upwards instead of the crest, an observer closes a circuit by means of a press-button when the pin 7 corresponding to the cigarette is due to be adjusted by the lever 15. A solenoid 19 is energized and the lever is pulled away so that the pin 9 remains in position b, and, on arriving at the point of intersection with the conveyer path, turns the cigarette about its axis as shown in Fig. 5. Pins which are not already in position bare moved into it by the action of a stop 22. The action of a photo-electric cell or of a device for contacting with the seam of a cigarette may be substituted for the manual operation of a pressbutton. A disc 4 may be arranged on each side of the conveyer, or the pins 7 may be carried on an endless chain moving at the same speed as the conveyer.

Title: Process of modifying the starch content of amylaceous material
IPC: D06M15/11
Filed: 1950-10-12
Abstract: The starch in amylaceous material, used for example in sizes, is modified and solubilized by heating an aqueous suspension of the material to a temperature sufficient to gelatinize the starch and then subjecting the gelled suspension to pressure-homogenization. The pressure-homogenization and/or gelatinization may be effected at temperatures below the boiling point, e.g. from 140 DEG  to 200 DEG F.  During gelatinization, the suspension may be boiled for a time so short that only partial or very incomplete cooking of the starch occurs.  Thickly gelled suspensions may be pumped under pressure into the homogenizing apparatus.  The viscosity of the suspension may be reduced by adding a dilute acid or enzyme before pressure-homogenization.  A wax, fat, dye or colouring agent may be added to the suspension before homogenization.  The viscosity of the homogenized suspension may be controlled by regulating the homogenization pressure which may range from 250 to 10,000 lb/sq. in., preferably from about 400 to 6,000 lb./sq. in.ALSO:In making a brewer's or distiller's mash an aqueous dispersion of unmalted grain is heated to about 200 DEG F, immediately pressure-homogenized to modify the starch present, cooled to 150 DEG F, mixed with malt, and the resulting mixture is re-homogenized to accelerate amylolysis.

Abstract: 283,285. Vickers, Ltd., and Lucas, O. D. Oct. 8, 1926. Retting.-In the preparation for textile and other purposes of fibrous vegetable materials such as flax, jute, hemp, ramie, and sisal, the materials after scutching are boiled in a solution of caustic soda of a strength not exceeding 2 per cent and then, with or without intermediate washing, are boiled in a vat containing a mixture of oil such as linseed oil and alkali. The materials may be again washed with cold water and then placed in a cold acid bath containing preferably acetic or hydrochloric acid, washed, and dried. A small proportion of sodium hypochlorite may be added to the acid bath, or chlorine may be blown in and the first washing water preferably contains weak alkali. The materials may remain throughout the treatment in reticulated containers in which they are laid loosely, the containers being moved about or reciprocated in each successive bath. The process as described is applicable to retted flax. If green unretted flax is treated, the material is first scutched, the boiling with caustic soda is dupli. cated, and the acid bath is made stronger. In the treatment of jute, two boilings in a 1 per cent solution of alkali are preferable, the proportions of oil and hydrochloric acid are slightly increased and the operations somewhat prolonged.
Patent GB-467001-A (GB)
Title: Improvements in and relating to methods of wetting or coating one metal with another
IPC: C23C14/02
Filed: 1936-09-15
Abstract: To enable a metal to be satisfactorily wetted by another metal of lower melting point it is first coated with a solution of a salt of a metal which will alloy with the wetting metal and then heated in a reducing atmosphere to break down and deposit the metal of the salt. The coated metal is then heated in a reducing atmosphere in contact with and to a temperature above the melting point of the wetting metal.  The method may be employed for coating metals, particularly metals such as molybdenum and tungsten and alloy steels such as chrome steel and nickel chrome steel, with other metals such as copper or silver solders, or for brazing metals in which case both parts to be brazed are coated with the salt solution and heated, copper being then melted at the junction of the parts.  Impregnated masses may be formed by coating metal particles with the salt solution, heating them to break down the salt, pressing the coated particles into the desired form, and then heating the mass in a reducing atmosphere in contact with the impregnating metal.  The method may also be used for repairing defective parts in shaftings &c.  In coating molybdenum with copper, silver nitrate is preferably used as the salt but the nitrates, nitrites, and chlorides of silver, iron, cobalt, nickel, and copper may be used.
