Patent GB-808290-A (GB)
Title: Cyanoethyl ethers of starch and process for the production thereof
IPC: A61K9/00
Filed: 1956-02-17
Abstract: The invention comprises a cyanoethyl ether of substantially ungelatinized starch in which only the surface of the starch granule is cyanoethylated.  The novel product may be obtained by treating an aqueous alkaline slurry of ungelatinized starch granules at a pH not exceeding 13 with acrylonitrile and discontinuing such treatment before appreciable gelatinization of the starch granules occurs.  The reaction conditions must be carefully controlled.  Sufficient water is used so that the starch-water slurry has a workable fluidity. While any strong alkali may be used to render the reaction mixture alkaline, it is preferred to use the quaternary ammonium hydroxides, or alkali metal hydroxides such as sodium and potassium hydroxides, in solutions containing less than 1 per cent by weight of the alkali metal hydroxide.  An excess of acrylonitrile is preferred, but preferably less than 3 mols. of acrylonitrile are used for each glucose unit in the starch.  It is desirable to regulate the amount of water and acrylonitrile in the reaction mixture so that the acrylonitrile is present slightly in excess of its solubility in the water present at the reaction temperature.  The temperature is preferably below 40 DEG  C. and may be as low as 0 DEG  C.  The time of reaction must be correlated with the alkalinity and the temperature.  Thus, at pH 12.5 and 35 DEG  C., gelatinization will begin if the reaction time exceeds 30 minutes.  Any type of starch, such as corn, sago, tapioca, potato, wheat and rice starches, may be utilized.  Surface-cyanoethylated starch granules having a degree of substitution of less than about 0.05 cyanoethyl groups per glucose unit are particularly useful in medicinal dusting powders (see Group VI).  In an example, raw corn starch is slurried in water with the addition of sodium hydroxide to give a pH below 13, acrylonitrile is added and the mixture stirred sufficiently to maintain a smooth slurry for 25 minutes at 35 DEG  C., after which time acetic acid is added and the cyanoethylated starch is filtered off, washed and dried.ALSO:A medicinal dusting powder comprises a mixture of 98 per cent by weight of surface cyanoethylated corn starch (for preparation see Group IV (a)) and 2 per cent by weight of magnesium oxide.

Abstract: 1,011,419. Axial-flow fans. WOODS OF COLCHESTER Ltd. Feb. 7, 1964 [Feb. 7, 1963], No. 5075/63. Heading F1C. In an impeller for a variable pitch axial-flow fan, in which the pitch of the blades can be varied while the impeller is rotating, the blades have hollow roots and are mounted thereby upon stub axles fixed into a split impeller hub, each stub axle having a portion of reduced diameter forming a shoulder for transmitting the centrifugal force to the hub. The impeller may have four or six blades and each blade is mounted by its root 15 on needle roller bearings 27, 28 on a hardened stub axle 11 fixed in the hub by a clamping ring 13 secured to the main hub part 12 by bolts (not shown). Preferably, the hub is recessed to receive a sleeve 18 which transmits any axial thrust but instead the hub may have an integral shoulder abutting a shoulder 17 on the stub axle. A needle roller thrust bearing 24 has one race 36 seating on the flange 35 of a split sleeve 34 bolted to the blade root, and the other race formed by a shoulder 23 of the stub axle or by an abutting washer. The parts of the thrust bearing 24 are held in contact when the impeller is stationary by a spring 39 and steel ball 41. The split sleeve 34 may have a grease nipple 38 and preferably has an oil seal 37. The hub parts 12, 13 may be of steel and the split sleeve and blades of cast aluminium alloy. Alternatively, each blade may be a synthetic resin moulding with a glass fibre filler and having a steel insert 42 in its root. The split sleeve 34 carries a pin (not shown) parallel to the blade rotational axis, which pin is connected through a link 44 and pin 45 with an axially movable ring 46. The ring 46 is moved through rods 56 to vary the pitch of the blades by a diaphragm 47 in accordance with a pressure communicated thereto through a stationary pipe and a rotating gland (not shown) screwed into a bore 57. Preferably, both ends of each link 44 have needle roller bearings. The pins on the split sleeve are so arranged that in the mid-angular setting of the blades they all lie in a common plane with the axes of the blades. In an alternative arrangement for adjusting the pitch of the blades, the pins locate a circumferential groove in an axially adjustable ring. Balance weight may be provided on the split sleeve parts to reduce twisting of the blades due to centrifugal force.

Title: Improvements in and relating to the preparation in powdered form of milk-containing mashed potatoes
IPC: A23L19/15
Filed: 1944-03-24
Abstract: Powdered reconstitutable milk - containing mashed potatoes are made by mixing cooked and mashed potatoes with milk and mashed potato seed powder prepared from mashed potato only, as described in Specification 566,167, to give a friable powder of 35-50, preferably 35-45, per cent. moisture reducing to the desired degree of fineness, as by sieving, and drying to a moisture content not exceeding about 7 per cent. by weight.  Alternatively, the powder may be dried and then reduced.  Reducing and drying may be effected by the methods described in Specification 566,167 and may be carried out in more than one stage which may alternate with each other.  The milk, as a 33 per cent. solution of milk solids, the latter preferably constituting about 10 per cent. of the mashed potato and seed powder on a dry basis, is obtained from evaporated separated milk or reconstituted from separated milk powder and is distributed uniformly as a fine spray in a mixer preferably of the Gardner type.  The product should pass a 30 mesh sieve and the coarse residue may be reconstituted preferably with hot water and mixed in with further ingredients to make more friable powder.  In an example, 25 lbs. cooked mashed potatoes containing about 80 per cent. moisture are mixed with 55 lbs. seed powder and a milk solution obtained by reconstituting 6 1/4 lbs. dried separated milk powder with 12 1/2 lbs. of water at 100-120 DEG  F.

Abstract: 952,003. Self-erecting tower cranes. ETABLISSEMENTS WEITZ S.A.-SOC. LES FILS DE JULES WEITZ-CHANTIERS ET ATELIERS DE CONSTRUCTION DE LYONWEITZ REUNIES. Feb. 14, 1962 [Feb. 14, 1961], No. 5687/62. Heading B8B. Telescopic movement between two sections 1, 2 of a tower crane causes the tower to be erected by a tie 5 attached to a chassis 3 by members 8, 9, which swings the tower about a pivot point 4 as it extends. The extension of the tower may be effected either by a separate mechanism 10 or by one of the crane motors which produces luffing, slewing &c. The pivots may comprise removable spindles so that the crane may be split into its component parts to facilitate handling. When in the horizontal position the crane may be slid longitudinally on the chassis to reduce overhang. Further sections may be added to the top of the part 2 of the tower when erected. If a flexible tie 5 is used the tendency for the tower to drop under gravity when its centre of gravity passes over the pivot 4 may be prevented by using jacks or by suitably positioning the pivot 4. One or both sections of the tower may be constrained to move horizontally on the chassis at the beginning of the erecting movement. To improve stability during erection the ballast may be carried below the chassis. The tie 5 is removed after erection of the tower.
