Title: Improvements in and relating to single stage hydraulic transmissions
IPC: F16H47/08
Filed: 1953-11-17
Abstract: 749,133. Variable-speed gear. LYSHOLM, A. Nov. 17, 1953 [Jan. 21 1953], No. 31914/53. Class 80(2) [Also in Group XXIX] In a hydraulic transmission the torque from a motor is conveyed to a driven shaft partly by a planetary gear and partly by a torque converter. If the ratio of maximum motor torque to the motor torque at the maximum motor speed is 1.2 or more about one third of the motor torque is passed over the hydraulic system and about two thirds directly to the driven shaft. At full throttle, the speed of the driven shaft is higher than that of the motor. If the ratio is less than 1.2, the greater part of the torque flows over the hydraulic system. In the hydraulic system, turbine blades are provided having a thick, well rounded leading edge and a strongly curved camber line, and guide vanes are provided having a well rounded leading edge but a thinner profile and a flatter camber line. In the embodiment shown in Fig. 1, in which about one third of the motor torque is transmitted over the hydraulic system, a driving shaft 1 rotates a flywheel 2 to which is attached, by a flexible coupling 3 a disc 4. The disc is secured to a shaft 5 having, at its other end, a flange 6 carrying a number of shafts 7 for planet gears 8. The gears 8 engage a sun wheel 9 and ring teeth 10 on a drum 11 formed integrally with a shaft 12. The 'sun wheel 9 is mounted on a hollow shaft 13 which through a friction clutch 15, can be connected to a hollow shaft 17 carrying a pump wheel 18 of the hydraulic system. Pump blades 20 are arranged facing blades 21 on a turbine rotor 22 which is mounted through a free wheel device 23 on the shaft 12. Stationary guide vanes 19 are provided. The sun wheel, shaft 17, and the pump may be braked by a brake 24 when the hydraulic system is disconnected by the free wheel device 23. In a second embodiment, Fig. 4, in which about twothirds of the motor torque is transmitted over the hydraulic system, the sun gear 9 is mounted on the driven shaft 40 and the ring gear 10 is mounted on a disc 41 attached to a hollow shaft 42 which, through a friction clutch 43 is connected to the pump wheel 18. The turbine wheel 22 is mounted on the free-wheel device 23 on a shaft 44 rigidly connected to the driven shaft 40. A second friction clutch is provided to connect the disc 41 to the shaft 40. If the second clutch is engaged, the first clutch is disengaged, and the whole of the motor torque is directly transmitted to the shaft 40.

Title: Method of utilizing whey for the production of foodstuffs and animal feeds
IPC: A23K10/28
Filed: 1976-07-30
Abstract: Proteins are isolated from whey and cereal products by first subjecting the mixture of the products mentioned to a starch hydrolysis, the whey serving as swelling agent and diluent during the hydrolysis. After separating off the unchanged protein as a first protein fraction, the low-molecular hydrolysis products resulting from the starch hydrolysis, preferably disaccharides and monosaccharides, are used to produce microorganisms. The single cell proteins produced in this manner are isolated as a second protein fraction. The two protein fractions can be used as food and feed additives.
Patent GB-506046-A (GB)
Title: Method of coating insulating materials on metal objects
IPC: H01J29/43
Filed: 1937-11-22
Abstract: 506,046. Insulation. FREEMAN, G. S. P. Nov. 22, 1937, No. 32083. [Class 36]. [Also in Groups XXIII and XL] A method of forming a coating of insulating material on a metallic surface comprises the step of oxidizing the surface, evaporating thereon a layer of insulating material which will wet the oxidized surface, and then baking the coating at a temperature in the vicinity of the fusing point of the insulating material. The process may be used for the production of a mosaic electrode for television transmission. Lithium borate is evaporated in vacuo on to the oxidized surface, and the coating is vitrified by stoving the article for a few seconds in an inert atmosphere at a temperature about 10‹ C. above the fusion point of the borato. The film can also be toughened by baking it in air at a temperature just below its fusion point. The process may be applied to very thin wires, or to grids of fine wire, which may be used in electron multipliers or like devices; or for constructing resistances or inductances which are required to operate with a relatively high load current.

Abstract: 963,991. Boring mills. COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Sept. 13, 1961 [Sept. 20, 1960], No. 32218/60. Heading B3T. [Also in Division F1] A vertical boring mill power transmission system comprises variable-stroke piston pumps 11, 12 and variable stroke piston motors 2, 3, 9, the stroke control mechanisms of the pumps and motors including pressure responsive elements 24 which superimpose on the control action of the mechanisms a further control action increasing the piston strokes to compensate for pressure liquid leakage. The worktable 1 is rotated by the motors 2, 3, energized by pump 11, and the motor 9 drives the lead screw 8. A cam 18 operates rack-and-pinion mechanisms 13, to adjust the piston strokes, through push-rods 14. The cam 18 ensures correctly phased speed increase of the table 1 with inward traverse of the lead screw 8. The elements 24 consist of telescopic links comprising a spring-loaded piston subjected to pressure liquid. Above a pre-determined operating pressure, the liquid overcomes the spring loading thereby extending the pushrod length. A threaded sleeve and spigot allows for fine adjustment of the push-rod length, the sleeve being clamped by a screw. In an alternative embodiment the ends of the push-rod 14 are articulated to a pivotallymounted link and the cylinder for the pushrod piston is fixed to a casing for the cam 18.

Title: Flame-proof resistors
IPC: H01H85/046
Filed: 1972-07-11
Abstract: 1359790 Resistors MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 11 July 1972 [13 July 1971] 32428/72 Heading H1S A flame-proof resistor comprises a substrate 1 of insulating material, e.g. glass, a resistive film 2, e.g. metal, metal oxide or carbon coated on the substrate, conducting terminals 3 and lead wires 4, and glass 7 applied to the film. When the resistor is overloaded, the glass is fused by the heat from the resistive film, and the film then melts, thus open circuiting the resistor. In examples, powdered glass is made into a paste with a mixture of adhesive material dissolved in an organic solvent, and applied to resistors, formed with grooves 6 to determine their value. A silicon insulating paint is then applied, and the resistors heat treated. Metal oxide resistors coated with the paste fused in 60-100 seconds after the application of a load 10 times the rated load, whereas conventional fuses took 5-10 minutes to fuse (e.g. Fig. 6, not shown). On fusing, the resistor temperature rapidly dropped, thereby preventing heat damage to adjacent components (Fig. 7, not shown). The overload standing characteristics are shown to be essentially the same as for conventional resistors. Embodiments are disclosed in which glasses having fusing temperatures of 340‹ and 480‹ C. respectively are used. If the substrate is cylindrical glass 7 may be formed as a ring round it. The glass may be restricted to an elongate shape lying between two adjacent grooves 6, and parallel either to the grooves or the axis of the resistor.

The dispersion may be prepared by reacting a phenol with an aldehyde in the presence of a basic catalyst for a period sufficient to produce a water-insoluble phenolic resole, and dispersing the resole, in situ, in an aqueous medium-containing gum ghatti and a thickening agent, wherein the aqueous medium contains sufficient water to enable a phase inversion to occur during the dispersing step. Preferably the resulting dispersion is heated for a period of time sufficient to increase the weight average molecular weight of the resole to 400- 3000, provided that the pH of the reaction mixture is not greater than 9 prior to the dispersion step. The amount of resole in the dispersion is preferably not greater than 50% weight, based on the resole plus water. The phenol may be monohydroxybenzene, an alkylphenol, a halophenol, p-phenylphenol, styrenated phenol or a bisphenol. The aldehyde may be formaldehyde or a formaldehyde donor, e.g. paraformaldehyde or hexamethylenetetramine, acetaldehyde, furfural or acrolein. Preferably 0À5-4 moles of aldehyde are used per mole of phenol. The basic catalyst may be an alkali metal or an alkaline earth metal hydroxide, oxide, or carbonate, an ammoniacal compound or an amine. The thickening agent may be guar gum, gum carrageenin, algin gum, locust bean gum or a water-soluble polymer, e.g. an ethylene/maleic anhydride copolymer, ionomers, polyacrylamide, or methylvinylethermaleic anhydride copolymer, and is generally used in an amount of 0À1 to 1 pbw per 100 pbw of phenol and is sufficient to increase the viscosity of the dispersion to at least 500 cp at 23 C. The gum ghatti is preferably used in an amount of 0À5 to 5 pbw per 100 pbw of phenol. The dispersions are infinitely dilutable with water. In the Examples aqueous dispersions are prepared by the preferred process above using as the phenolic component:- either phenol, bisphenol A, p-tert-butylphenol or a mixture of phenol and p-nonylphenol; as the aldehyde component: aqueous HCHO; as the neutralizing agent to bring the pH of the reaction mixture to below 9:- aqueous H3PO4 or H2SO4; as the thickening agent:- guar gum, locust bean gum, sodium alginate or ethylene/maleic anhydride copolymer; and gum ghatti as the interfacial agent.
