Patent GB-842661-A (GB)
Title: Lubricating greases
Inventor: BUTCOSK RICHARD AUGUSTINE
Filed: 1957-08-27
Abstract: Lubricating greases comprise a mineral lubricating oil and a minor proportion, sufficient to form a grease, of a mixture of soaps the acid components of which comprise by weight 15 to 80% of wool grease fatty acids and the balance aliphatic acids of at least 12 carbon atoms and the metal component of which comprises either lithium or a mixture of lithium and sodium in a molar ratio between 15 to 1 and 3 to 1 provided that when there is a mixture of preformed soaps of lithium and sodium there shall be a lithium soap of an aliphatic acid and sodium soaps of wool grease fatty acids.  The mineral oil should have a viscosity above 1 e.g. 60 to 6,000 SUS at 100 DEG F. and may be naphthenic or paraffinic.  Wool grease fatty acids are obtained by the acidification of the soap solutions obtained in the manufacture of lanolin.  The other aliphatic acid may be for example a stearic, hydroxy stearic, oleic, palmitic, hydroxy palmitic, myristic or hydroxy myristic acid or a mixture of such acids include naturally obtained materials such as vegetable, animal and fish fatty oils and their hydrogenated fatty derivatives, e.g. stearin, hydrogenated tallow or soya bean fatty acids, hydrogenated fish oils and partially hydrogenated marine, vegetable and animal oils.  The greases can be prepared by incorporating preformed soaps in the oil or by forming the soaps in situ and the product may be slightly acid (corresponding to up to 0.5% by weight oleic acid) or alkaline (up to 0.2% lithium hydroxide).  Optional ingredients are antioxidants, e.g. amines, phenols and sulphides, and lubricity improving agents, e.g. free fat, fatty acids, esters of alkyl and/or aryl acids, sulphurised fats and lead soaps.  The grease may contain 5 to 30% by weight of the soaps and up to 10% of the optional ingredients.

Abstract: In producing dry-cooking, fluffy rice, polished rice, brown rice, wet-cooking rice or broken rice, preferably containing under 16%, by weight, of moisture, is steamed for 2 to 15 minutes at a rice temperature between 75 DEG  and 130 DEG C. and its moisture content is then raised to between 16% and 24% by adding water, dilute hydrochloric, phosphoric, nitric, sulphuric, citric, tartartic, or lactic acid, aqueous hydrogen peroxide, or a buffer solution having a pH between 3,5 and 5,5, e.g. containing citric acid and disodium phosphate.  The moistened rice is tempered, to distribute the moisture more uniformly and allow any caked rice to disintegrate, then heated, e.g. for 2 to 20 minutes, in live steam at a gauge pressure between 0,3 and 1,0 atmospheres and finally dried, e.g. until it has a moisture content of 16% or below.  Small amounts of oxidants, such as hydrogen peroxide, chlorine dioxide and nitric acid, may be added at any stage of the process.  Specifications 493,528, 579,981 and 737,446 are referred to.

Filed: 1950-11-10
Abstract: 705,062. Moulding concrete. JOHNSON. J. G. A. Nov. 10, 1950, No. 27556/50. Classes 22 and 87 (2) In a method of removing excess mixing water from plastic concrete, water is drawn from the concrete into an enclosed chamber which is in communication with the concrete and is provided with means for preventing the admission of concrete particles the water being drawn from the concrete by causing a current of air to create a reduced pressure within the chamber and the air with excess water being discharged from the chamber in the form of a spray. Fig. 9 shows a mould for making pipes and hollow slabs. comprising sides 40, stiffeners 41. tie rods 42. bottom plate 43 and support beams 44. Within the concrete is disposed a suction chamber 21<1> having perforations 17 through which water passes from the concrete C to the inside of the chamber, which is lined with a cylindrical screen 23. In the upper end of the chamber is adjustably screwed a pipe 35 having a nozzle 36 which co-operates with a jet 37, venturi fashion, the jet being screwed in the base of chamber 21<1>. Compressed air is blown through pipe 35, nozzle 36 and jet 37 and creates a reduced pressure within chamber 21<1>, the water in the latter being carried off as a spray. The chamber 21<1> may be held in fixed position in the mould and vibrated, or may be moved up and down with a plungerlike action. Fig. 2 shows a suction chamber 1 which by means of handles 10 is slid to and fro over the surface of concrete to press thereon and squeeze water to the surface. Suction through flexible hose 8 draws air through inlet 5 into the chamber and through a restricted opening 7. The chamber has perforations 3 covered by metal gauze 4. Fig: 6 shows a device similar to that of Fig. 2, but here the suction is produced by a venturi tube device as in Fig. 9. Fig. 4 (not shown) illustrates a device for de-watering deep concrete such as a wall construction.

[Also in Group XXXV] In a motor control system three series arrangements of controlled rectifiers supply the motor from a three-phase supply [Fig. 2). Fig. 1 shows one of the high voltage series arrangements of controlled rectifiers 2, 3, 4, 5 which has one uncontrolled rectifier 6 at the upper end, a resistive (or resistive and capacitative) main voltage divider 8, 9, 10, 11, 12, a capacitative (or capacitative and resistive) control voltage divider 13, 14, 15, 16 connecting the ends of the series arrangement and the control electrode of each controlled rectifier except the lower end rectifier 2, which has an uncontrolled rectifier 7 in parallel with it, but with opposite polarity, and a control circuit 19. The capacitor 16 has half the capacitance of each of the equal capacitors 13, 14, 15. When the controlled rectifiers are blocking, the voltage dividers, together with the rectifiers 6 and 7, maintain the control electrode of each of the rectifiers 3, 4, 5 negative with respect to its cathode, whichever the direction of the voltage applied to the series arrangement. To switch the rectifiers on, when the upper end is positive, the rectifier 2 is triggered by the unit 19. Consequently, points 2a and 2b are connected, and rectifier 3 is triggered by the charge on capacitor 13. Similarly, rectifier 4 is triggered by capacitor 14, and so on. Diodes may be connected between the control electrodes and the control voltage divider, and there may be resistors connected between the control electrode and the cathode of rectifiers 3, 4, 5 (Fig. 2).

When a switch 312 in the oscillator circuit A is closed, a battery 313 is connected into the self-oscillating circuit of a transistor 301 and oscillation transformer 303, an output capacitor 304 being connected in the secondary circuit thereof. While the switch is closed, the circuit continues to oscillate so that capacitor 310 continues to be charged and discharged to produce a succession of sparks at gap 311. Again, Fig. 6 (not shown), the oscillation circuit may be controlled by a switch (612) which connects a source energy storing capacitor (614) either to the battery (613) for charging or to the oscillation circuit when sparks are required. The number of sparks produced is then restricted by the charge on the capacitor (614). Also, Fig. 7, (not shown), a resistor (718) may be arranged in series with the spark gap to prolong the duration of discharge. Alternatively, an induction element, e.g. coil (819), Fig. 9, (not shown), may be provided.
