Title: Improvements in or relating to processes for the preparation of extracts from aromatic plants, entirely soluble in hot water
IPC: A23L27/10
Filed: 1945-10-16
Abstract: Extracts from aromatic plants entirely soluble in hot water are prepared by subjecting a plant, or part thereof, to the passage of aqueous saturated steam so that the volatile elements are distilled and the water-soluble non-volatile elements are extracted, concentrating the solution containing the water-soluble non-volatile elements and reuniting the concentrated part with the volatile elements.  The concentrate containing the water-soluble non-volatile elements may be mixed with a solid water-soluble physiologically inactive product such as lactose, saccharose, sorbose, sorbite or mannite before being reunited with the volatile elements so as to give either at once or after dessication a product in powdery, granular or paste form. The plants or parts thereof which may be treated include camomile flowers, clove flowers, elder flowers, anise seeds, coffee beans, cardamom flowers, caraway seeds, sweet-fennel seeds, vanilla pods or roots; garlic, calamus, galangale or ginger roots or rhizomes; bergamot, lemon, tangerine or orange peels; eucalyptus leaves, mat<\>ae, mint, tea, vervain, hyssop, marjoram, melitot and thyme.  The Specification as open to inspection under Sect. 91 comprises also the separation of the volatile elements by extraction with steam, condensation and separation, extraction with an organic solvent, enfleurage, distillation in a high vacuum and condensation by cold, or extraction with the help of a hot gas such as carbon dioxide and subsequent condensation by cold, separately forming the aqueous extract of the water-soluble non-volatile elements, concentrating the aqueous extract and uniting it with the volatile elements.  This subject-matter does not appear in the Specification as accepted.

Patent GB-700860-A (GB)
Title: Improvements in or relating to electrical ignition devices
Inventor: CARINGTON CHARLES MOLYNEUX
Filed: 1950-11-07
Abstract: A shaped sparking-plug body, e.g. of alumina, is partially fired to render it porous, is impregnated with a metallic compound and heated whereby the body is vitrified and metal is deposited from the decomposed compound.  The temperature of vitrification must be below the melting point of the metal. Specified compounds are those of the platinum group metals. e.g. platinic chloride in solution in water and glycerine.ALSO:A semi-conducting body of a sparking plug is produced by forming a shaped body from material capable, upon partial firing, or being converted into a porous insulator; firing the body at a temperature insufficient to produce complete vitrification of the insulator, incorporating into the pores at the working surface of the body a metallic compound which will decompose on heating leaving a finely divided metal of a melting point higher than the vitrification temperature of the insulator, and then heating to vitrify the insulator and decompose the compound but without melting the metal.  Preferably impregnation is by solutions of salts of the platinum group metals, singly or in combination. Alumina is the preferred material.  When certain salts are used a reducing agent in the solution or firing under reducing conditions may be necessary.

Abstract: 322,568. Graseby, R. C. Sept. 29, 1928. Automatic transmitters.-Relates to a transmitter for repeatedly transmitting a code signal constituted by current impulses of different lengths. The signalling circuit is completed at contact 10 by a pivoted lever 4 which carries a pair of cams 6, 7 (Fig. 5) cooperating with pins 9, preferably adjustable, on a disc 8 which is rotatable by a motor 12. The transmission includes a differential gear in the oil-filled casing 3, the planet wheels 18 of which are mounted on the shaft 17 of the disc 8, whereas the sun wheel 16 is driven by the motor. A spring-controlled armature lever 23, pivoted at 24, in the unattracted position shown engages a pin 22 on a disc on the shaft 17, and when attracted by the electromagnet 27 moves to engage one of a series of pins 20 on the sun wheel 19. The shaft 17 carries another disc, a pin 32 on which engages a star wheel 33 having as many arms as there are signals of a series to be sent out. The star wheel 33 is mounted on a shaft 34 which carries two cams 35, 36, of which 36 engages a projection 40 on the arm 4 and 35 engages a spring-controlled lever 37 which operates a switch 30. The particular series of signals instanced, comprises the sending of the letters A, B nineteen times, followed by a space corresponding to four such signals, and then a final signal, the star wheel thus having twenty-four arms. In operation, a push-button or time switch 41 energizes the electromagnet 27 which attracts its armature 23 and frees the shaft 17. Also, a relay 28 closes at 29 the circuit of the motor 12 which rotates the shaft 17 and disc 8. After a short time, the cam 35 short-circuits the switch 41 at contacts 30. After nineteen revolutions of the disc 8, the cam 36 engages the projection 40 and holds the lever 4 in the closed position during four more revoltitions, and the lever 4 is then actuated to send the final signaJ. The cam 35 then opens the circuit at 30 to de-energize the magnet 27 and relay 28, the pin 22 engaging the released armature 23 to bring the apparatus to rest ready for the next transmission. Specification 323,277 is referred to.
