Patent GB-639935-A (GB)
Title: Improved process for the extraction of sugar from molasses
Filed: 1947-05-09
Abstract: In the extraction of sugar from molasses by precipitation with barium hydroxide and subsequent carbonation, the concentration of barium ions is maintained above that necessary for the precipitation of mono-barium saccharate by addition of hydroxide sufficient to replace the ions removed, and crystallization is initiated by the introduction of mono-barium saccharate crystals separately produced from pure sugar and barium hydroxide.  Barium hydroxide solution is added to slightly dilute molasses at a temperature not exceeding 20 DEG C.  The barium hydroxide is added to maintain the pH value until that value suddenly increases owing to the cessation of the formation of the saccharate.  The precipitate is filtered off, washed with barium hydrate solution, worked into a paste with water, and treated with carbon dioxide or gases containing carbon dioxide.  U.S.A. Specification 1,878,144 is referred to.

Title: Improvements in or relating to the treatment of wool and the like to reduce felting and shrinking
IPC: D06M15/423
Filed: 1946-04-29
Abstract: Textile material consisting wholly or partly of wool is rendered more resistant to felting and shrinking by impregnating it with a strong solution of methylol urea (i.e. the condensation product between an equivalent molecular ratio of urea and formaldehyde produced on standing of the reagents in neutral solution for several hours), squeezing, drying, and curing at 80 DEG -135 DEG  C., and then impregnating with a solution of a strong mineral acid, squeezing, rinsing, drying, and curing at 90 DEG -135 DEG  C.  The amount of resin deposited may be 10-15 per cent by weight of the wool.  The methylol urea solution is preferably of a concentration of at least 50 per cent by weight.  The ratio of formaldehyde to urea may be slightly in excess of the equimolecular proportion to allow for evaporation of formaldehyde during the treatment.  To improve the feel of the treated material it may be scoured, and it may be treated with a cation-active or other softening agent.  The curing may be effected with the aid of infra-red radiation.  The wear-resistance of the material is also improved by the antifelting treatment. In examples, wool yarns, woven and knitted fabrics, and hosiery, are subjected to the anti-felting treatment.

Filed: 1932-05-06
Abstract: 392,355. Drying grain. PELLEGRINO, G. and PELLEGRINO, M., 40, Corso Dante, Turin, Italy. May 6, 1932, No. 13166. [Class 34 (ii).] Apparatus for drying malt and other grain comprises a tower A having superposed rows a .. h of roof-shaped conduits through which currents of air at different temperatures are admitted and discharged in turn, valves being provided in the feeding conduits for the currents of heated air to control the admission and temperature of the air fed to the different points in the tower, and means being also provided for ensuring a bodily descent of the grain through the tower, all the grain passing through the drying zones at the same speed. The means employed for ensuring bodily descent of the grain may consist of rocking slats 7 arranged on a cradle 8 under two openings between the roof-shaped conduits of the lowest row b, the slats being wider than the openings, and the conduits being continuous and so steep that the grain meets with no resistance therefrom in its descent. The cradle 8 is operated by a rocking lever 9, which is in turn operated by a rotating shaft 10 through a crank or cam mechanism. The oscillation of the cradle 8 can be regulated by means of adjustable screw clamps 11 thereon. To secure a uniform treatment of the grain at the beginning of the operation, flap valves 22, Fig. 5, carried by pins 23 capable of oscillation are provided, these valves in their horizontal position forming shutters to support the grain supplied at the top, and in the vertical position the grain to fall unhindered. The valves 22 are operated from outside the tower A by means of levers or the like, the opening and closing positions being determined by stops 24 on guiding plates 25. Valves 22 in the same horizontal plane may be operated simultaneously or separately. The heating of the air currents supplied to the conduits a . . h is effected in a steam heating apparatus B comprising a chamber enclosing four units of steam coils connected in series, steam being admitted at the top and flowing in counter current to air blown in a zigzag direction from the bottom of the chamber. Openings 20a, 20c, 20e, 29g in the wall of the chamber B communicate through conduits 21a, 21c, 21e, 21g with collectors 4a, 4c, 4e, 4g supplying air through openings 3a, 3c, 3e, 3g to the alternate roofshaped conduits a, c, e, g respectively. The grain in its descent may thus be subjected to the action of four air currents of increasing temperatures, which in the case of malt may be 30‹, 60‹, 80‹, and finally 100‹ C. or more respectively. The valves provided in the conduits 21 for controlling the quantity and temperature of the air currents tapped at different points from the heater B are operable from the outside.

Abstract: 824,905. Fusible cut-outs. BELLING & LEE Ltd. April 25, 1958, No. 13167/58. Class 38 (1). A ring-main fuse or a high-breaking capacity fuse is made of a silver or other fusible element 1 surrounded by a filling of silica sand or diatomaceous earth in a ceramic tube 6 aud having one end secured to erd cap 7 by a pellet of solder 9 saturated with silver and the other end gripped between a notched plate 5 of ordinary solder and closure cap 13 (Fig. 7). During manufacture the solder pellet 9 is melted by standing the incomplete assembly on a hot-plate, the use of solder saturated with the material of the fusible element preventing any weakening of element 1 by combination of material from that element with the solder pellet. Subsequently the assembly is stood on a vibrator 11 (Fig. 5), and the filling inserted. The alloying of solder from plate 5 with element 1 in overload conditions reduces the melting point of the element so that the fuse blows in conditions of comparatively low overload.

Abstract: 1,055,811. Thermal regenerators. SIEMENS-SCHUCKERTWERKE A.G. March 31, 1964 [March 30, 1963; Jan. 14, 1964; March 5, 1964], No. 13254/64. Heading F4K. In a thermal regenerator for a furnace, in which solid particles are used as a heat transfer medium, the gravity assisted flow of particles is controlled by a flow of gases between the particles and in counter-current to the flow of the particles. Fig. 1 shows a vertical section through one possible arrangement. Fresh combustion air to be warmed enters, through duct 21, a lower chamber II where it penetrates through a bed of hot heat exchange particles 23 before passing through duct 22 into a furnace V. Hot exhaust gases from the furnace V enter an upper chamber I, via duct 11, and penetrate a bed of cold heat exchange particles 13 before being discharged out of duct 12. The particles enter chamber I through an inlet pipe 14 and a distribution network 15 and are deposited evenly on a channel bed 16, Fig. 2 (not shown). The passage of the particles through the channel bed 16 is controlled by the flow of exhaust gases through the apertures 36 which loosens the particles enabling frictional resistance to be overcome. In the absence of gas flow, no particle flow occurs, but when more than a certain minimum gas flow is present, the particle flow decreases with increasing gas flow in accordance with curve A of Fig. 10 (not shown). From chamber I, the particles pass, via a connecting duct 20 and another distribution network 25, to the lower chamber II where they are deposited evenly on a channel bed 26, Fig. 4 (not shown). The passage of the particles through the channel bed 26 is controlled by the flow of fresh combustion air through the apertutes 46 and ducts 48. The particle flow increases with increasing gas flow in accordance with curve B of Fig. 10 (not shown). The particles then collect in a pipe 24 and are returned to the inlet pipe 14. Valves 71, 72, in the by-pass ducts 73, 74, are controlled by a regulator 76 in response to the pressure drop across the column of particles 77 in duct 20 or in response to photo-electric means. Valves 65, 66 may be arranged to operate in conjuction with the valves 71, 72, in order to more quickly stabilize violent departures from the normal operating conditions. Valves 67, 68 may also be included. The ducts 48 may have slide valves 53 which can cover or uncover apertures in the walls of the ducts as in Fig. 6 (not shown). Slide valves may also be provided for the apertures 36, Fig. 2b (not shown), and 46, Fig. 6.
