Title: Multi-frequency frame scan generator for television apparatus
Inventor: NURSE MICHAEL JOHN DENNANT
IPC: H03K4/24
Filed: 1961-05-12
Abstract: 972,303. Sawtooth circuits. PYE Ltd. May 11, 1962 [May 12, 1961], No. 17411/61. Heading H3P. [Also in Division G3] In a frame scan generator for television equipment having a bootstrap stage V1 to linearize the charging rate, an output from the bootstrap stage is D.C. restored and rectified so as to provide a voltage which controls the charging rate in such a way as to maintain the scan amplitude constant despite changes in frame frequency. As shown in Fig. 2, a bootstrap valve V1 is provided to linearize the charging of capacitor C3. The voltage at the cathode of V1 is amplified by V4, D.C. restored by diode D1, rectified by diode D2, the resulting D.C. voltage being fed to valve V5 so as to control the charging current of C3 and hence the scan amplitude. The frame oscillator may be a free-running multivibrator or blocking oscillator. In Fig. 1 (not shown), V4 is omitted and the control valve is connected in shunt with the charging circuit. Specification 934,641 is referred to.

Title: A new or improved process and apparatus for the extraction of tallow, fat, grease, oil and the like, from bones, fatty substances, fish, skins, offal, seeds, and the like
IPC: C11B1/10
Filed: 1922-06-24
Abstract: 200,344. Rooke, A. G. Shirling-. June 24, 1922. Fats and fatty oils, extracting by solvents &c.- In the extraction of fat or oil from bones, fish, skins, offal, seeds, or other fatty substances a series of jacketed digesters is employed, the jackets of the second and subsequent digesters. receiving the hot vapours from the interior of a preceding digester and, it may be, from the solvent-recovery still. The apparatus shown comprises two secondary extractors B, C, heated by solvent and vapours passing from a primary extractor A through pipes 12, 13, 14, 15. The seeds &c. are first heated in the extractor B or C, the oil extracted being sucked through pipes 18, 19, 20 to a tank 21, and then blown by steam in pipe 23 to a clarifying-vat. The seeds are then transferred to an extractor A which is heated by steam supplied to the jacket through pipes 5, 6 and is fed with solvent from a reservoir 1 by pipes 2, 3. The extract is blown to a solvent recovery and refining still 10 by admitting steam to extractor A by pipe 11. The steam condensed in the jacket flows to a steam trap 7. The solvent &c. from the jackets 16, 17 is led through pipes 24, 25, 26 to a condenser 27 provided with a siphon 28 for running off condensed water, and a pipe 30 for conducting the solvent to a vaporizer 31 connected to the reservoir 1. A third series of digesters heated by the vapours from the interior of the secondary extractors B, C and in which the seeds &c. are treated first may be provided. Treatment in extractor A may be dispensed with if complete extraction of oil is unnecessary, as in the treatment of bones to leave a residue for grinding to meal for pigs or poultry. The extractors used are preferably of the kind described in Specification 200,345, [Class 64 (i), Heating liquids &c.].

Abstract: 1,004,742. Rotary-piston internal combustion engines. DAIMLER-BENZ A.G. April 29, 1964 [May 10, 1963], No. 17838/64. Heading F1F. In a rotary-piston trochoidal type I.C. engine comprising a three or more-sided piston rotatably mounted on the eccentric portion of the output shaft and planetarily rotatable in the engine casing and having gearing to maintain the speed of rotation of the piston in a fixed ratio to that of the output shaft, a gearwheel of the gearing disposed on an end portion of the casing or on the piston is resiliently mounted for displacement within limits in its peripheral direction. As shown, a pinion 6, Fig. 2, concentric with the output shaft 4 and mounted on a casing end portion meshes with a ring gear 7 fixed to the piston 5. The pinion 6 is formed as part of a sleeve 14 which projects beyond the end portion 3 of the engine casing and is formed on its outer end with a plurality of equally-spaced recesses 16 into each of which projects a bundle of leaf-springs 17, Fig. 3. Each bundle of springs extends in a radial direction into a recess 18 in an annulus 19 secured to the end portion 3 and are deflected in the rotational direction 10 of the piston to urge the sleeve 14 and pinion 6 in that direction. To provide limited peripheral movement of the pinion a bolt 11 fast on the annulus 19 engages in a groove 20 in the sleeve 14, normally pressing against an end face 21. Forces through irregular acceleration and retardation of the piston acting on the gearing in a direction opposite to the piston rotation 10 are resiliently transmitted through the pre-tensioned bundles of leaf-springs 17 within the limits of play 13 in the groove 20.

Title: A process for the recovery of sterols
Filed: 1940-12-20
Abstract: 547,324. Extracting sterols. ASCH, H. Dec. 20, 1940, Nos. 17937/40 and 111/41. [Class 2 (iii)] Sterols are recovered from fats by a process which comprises splitting the fats, removing the glycerol, distilling the remainder by low temperature low pressure distillation to remove the fatty acids and leave as a residue the sterols which are then extracted from such residue by one of the known methods for the extraction of sterols. Methods for extracting the sterols which are particularly referred to comprise subjecting the residue one or more times to a repeated cycle of splitting, removal of glycerol, and low temperature low pressure distillation followed by working up by saponification with alkali and extraction with a solvent. Alternatively the residue may be subjected to saponification with caustic in methyl alcohol solution followed by filtration of the soap solution. Finally in the case where an aqueous caustic saponification has been used, salts such as calcium chloride may be added to precipitate the soap in insoluble form. In examples (1) Linseed oil is split in an autoclave at 150 pounds steam pressure using zinc oxide as a catalyst, the glycerol is removed and the fatty acid removed by a low temperature low pressure distillation and the sterols extracted ; (2) Soya bean oil is split as in example (1) and worked up in a similar manner, the splitting and distillation being repeated until substantially all the fatty acids have been removed.

Abstract: 704,022. Gravity separation of liquids. STANDARD OIL DEVELOPMENT CO. May 5, 1952 [July 30, 1951], No. 17997/51. Class 46 Liquids are separated in an apparatus comprising a settling zone provided with two drawoff pipes each having an upper discharge point above the top of the settling zone and a lower liquid entry point within the zone, the upper discharge points being adapted to be maintained at a common pressure and the ratio of the heights of the upper discharge points above a desired liquid-liquid interfacial level being the inverse ratio of the densities of the liquids they are to withdraw from the zone, the lower entry ends of the draw-off pipes to withdraw the heavier and lighter liquids being respectively below and above the interfacial level. An oil stream 2 and an aqueous treating stream 3 are continuously fed to the lower end of a column 1, in a contacting zone 4 of which they are mixed together, e.g. by injecting the oil through a nozzle or by mechanical agitation. In a packed section 5 the oil drops coalesce prior to their separation from the aqueous phase in a settling zone above the section 5. A draw off pipe 8 for the aqueous phase has is lower (entry) end below the liquidliquid interface where it is fitted with a shroud 9 to prevent entry of oil droplets. The discharge point is at a height h<SP>1</SP>, above the interface and vented to the atmosphere. Similarly the oil draw-off pipe 11 has its lower end above the interface and its discharge point a height h' above it. It also is vented to the atmosphere. The heights h' and h<SP>2</SP> are connected by the relation:- h 1 /h 2  density (oil)/densitiy (aqueous phase) In a second embodiment the oil and aqueous phases flow in the column in countercurrent, with a packed section located between their entry points. The aqueous phase collects at the foot of the column and the oil at the head, though the interface is near the foot of the column. According to the Provisional Specification the invention may be applied to three or more liquids.
