Patent GB-1014801-A (GB)
Title: New products derived from starch
Inventor: THEWLIS BASIL HUGH
IPC: C08B30/12
Filed: 1960-12-22
Abstract: A cooled mixture of starch or flour, having not substantially less than its ordinary equilibrium moisture content, and a substance which will promote gelatinization of the starch granules is mechanically sheared, the consistency of the mixture being such that the shearing forces disrupt the starch granules, and the magnitude and duration of the shearing forces being sufficient to produce a product which exhibits rubbery or plastic-like properties.  The process may be applied to wheat starch or wheat flour containing e.g. 12-13% moisture.  The gelatinization-promoting substance may be glycerol, ethylene glycol, propane-1; 3-diol, butane 1;4-diol, aqueous formaldehyde; phenol, glyceryl monoacetate, 2-amino-propane-1;3-diol, pyrogallol, phloroglucinol, aniline, catechol, resorcinol, hydroquinone, butane-2; 3-diol, water, dihydroxyacetone, diethanolamine, oxalic acid, dimethylol urea cyclohexane 1;3-diol and formamide.  The flour or starch is mixed with the gelatinizing agent and fed into a machine, preferably having a grinding or similar action, capable of exerting strong shearing forces.  The reaction mixture may be cooled by an external bath to prevent charring. The proportions of starch or flour and gelatinizing agent are chosen so that a substantial degree of resistance to the machine is provided. For example, the proportion of water or glycerol, when used, should not exceed 20% by weight, giving a mixture which is still a free-flowing powder.  In an example, a mixture of raw flour or wheat starch (85%) and water or glycerol (15%) is masticated in a vertical masticator (uni-rotary mixer) for 0.5 hours, the reaction mixture being cooled by a cold-water jacket.  Residual gelatinizing agent may be removed from the resulting plastic or rubbery mass by extraction with a solvent e.g. alcohol. The product may be used as a baking additive, edible packaging material, and on the formulation of plastic compositions, detergents, adhesives, paper, textile sizes and coating compositions.

Title: Free piston vibratory powersource
IPC: F15B21/12
Filed: 1971-09-28
Abstract: 1362213 Vibrators VULCAN IRON WORKS Inc 28 Sept 1971 [10 Dec 1970] 45219/71 Heading F2X A linear vibrator comprises a piston member  50 reciprocal within bores 18a, 20a defined in a cylindrical body 12 and including an elongated rod with an enlarged diameter radial piston 52 midway between opposite ends of the rod. A pair of piston-rings 54 are mounted on the piston 52 which reciprocates in a large diameter bore 18a of a central expansion cylinder 18 of the body 12. The rod end sections or piston-rods 56 each have a plurality of piston-rings 58 adjacent their outer ends and slide in the bores 20a of compression chambers 20 of the cylindrical body 12. The body 12 terminates in heads 16 secured together by tension rods 22, and the lower head (not shown) is provided with a pair of coupling jaws. The vibrator is supported from a cable or pin by means of a clevis (not shown) attached to a support plate mounted on the rods 22. Stacks of spring washers (or coil springs) are provided on the rods 22 on either side of the support plate 40. The inner ends of the chambers 20 are formed with annular recesses 20c housing sealing ring assemblies 64 which seal opposite ends of the expansion cylinder bore 18a. Pressurized fluid from a supply line 70 passes via a feed passage 19 to annular passages 20d formed in the chambers 20 coaxially and outwardly adjacent the sealing ring recesses 20c. As shown, with the piston member 50 in its uppermost position, the pressurized fluid can flow from the upper annular passage 20d via passages formed by flats 56b in the upper pistonrod 56 to the expansion cylinder 18 above the piston 52, forcing the piston member 50 downwards. The supply of pressurized fluid is cut off when the upper flats 56b fall below the upper sealing ring assembly 64 and the fluid in the cylinder 18 then further expands adiabatically until the piston 52 exposes a pair of exhaust ports 18b in the wall of the cylinder 18. During the downward stroke, the fluid entrapped in the lower chamber 20 below the lower piston-rod 56 is being compressed and acts as an air spring with a cushioning effect. When the fluid being compressed attains a sufficient pressure, downward movement of the piston member 50 is stopped and the compressed cushioning fluid begins to expand and move the piston member in the upward direction. In the lowermost position of the piston member 50, flats 56b on the lower piston-rod 56 are adjacent the lower sealing ring assembly 64 so that pressurized fluid may enter the expansion cylinder 18 below the piston 52. The rate of reciprocation and the forces developed by the vibrator are controlled by supplying pressurized fluid to the opposite ends of the chambers 20 from a feed pipe 78 through a bore 18e defined in the expansion cylinder 18 and communicating with the chambers 20 by inclined bores 20g in the walls of the latter. Annular resilient shock-absorbers 60 provided in the heads 14, 16 are used only for safety purposes in case too great a pressure is used on the power side of the system.

Title: Rotary pump
IPC: F04D13/04
Filed: 1965-10-26
Abstract: 1,132,751. Centrifugal pumps; turbines. WORTHINGTON CORP. Oct. 26, 1965 [Feb. 24, 1965], No.45226/65. Headings F1C and F1T. A submersible centrifugal pump for pumping ballast water from a compartment of a ship comprises an impeller 28 which draws the water through an inlet passage 12 and delivers it via a diffuser passage 50 to an outlet 55 connected to a rising main. The pump is driven by a turbine comprising rotor blading 30 formed on the impeller 28 or otherwise connected to it. An auxilary pump located above the compartment delivers water via a downpipe and an inlet passage 16 to nozzle vanes 33 and thence through the turbine rotor blading 30 to drive the turbine. On leaving the blading 30, the water enters the diffuser passage 50 to join the water discharged by the impeller 28 and to exert an ejector effect which assists the pumping action. The diffuser vanes 54 have projections adjacent the rotor blading 30 to form ejector vanes. Alternatively, separate ejector vanes may be used. The diffuser passage 50 reduces the fluid velocity to minimize the losses incurred in passing around the obstacles 16, 24. Thereafter, the velocity is increased towards the outlet 55. The turbine may be driven by a liquid different from that being pumped. The two liquids thereby mixed together may subsequently be separated in a settling tank or a centrifuge. Alternatively, the turbine may be driven by steam which condenses and mixes with the pumped water. The turbine nozzle may be of partial admission type. The impeller 28 may be carried by a shaft journalled in a bearing. Alternatively, it is carried by a bush 66 which is journalled on a stationary shaft 27, either directly as shown or through the intermediary of ball bearings. Lubricant, which may be the fluid being pumped and may be cleaned by passing it through a cyclone separator, is supplied through passages 81, 82, 83, 84 into chambers 85, 85' formed by flats 61, 62 on the shaft 27, and returns to the pump inlet via the clearance between the bush 66 and a thrust collar 69 and also via passages 90. In an alternative arrangement, Figs. 18-20 (not shown), the pump discharges through a volute (201), while the turbine driving fluid is admitted through a centrally disposed inlet (200) at the top of the casing.

The first pressure reduction valve 18 is supplied with compressed air from a conduit 22, a valve body 25 connected to a diaphragm 21 urged against a valve seat 26 by a spring 27, preventing the flow of gas to chamber 28 and the ejector 24 unless there is compressed air in the balance chamber 29 acting against the diaphragm 21 to open this valve. The pressure of air from the conduit 17 in the chamber 29 also determines the size of chamber 28 as a result of the movement of the diaphragm 21 and consequently controls the amount of pressure reduction in valve 18 and so controls the pressure of air supplied to the ejector. The pressure of air in conduit 17 is controlled by the trigger 14 acting through an adjusting spring 6 and a valve lifting finger 18 on a valve body 8, the degree of compression of this adjusting spring 6 determining the pressure of air delivered from conduit 15 to conduit 17 and thus the trigger 14 determines the flow of spray material from the ejector 24. A fine pressure equalisation opening 30 in balance chamber 29 allows the release of pressure from this chamber. In the embodiment described the spray material is charged electrostatically, this being by way of a high voltage supply cable 9 to the gun. The gun may be used to spray such materials as paint powder, concrete, fiber cuttings, sand and steel blasting grit. When the gun is not adapted for electrostatic spraying the spray may be assisted by auxiliary pneumatic spray nozzles at the tip of the gun.
