Patent GB-734108-A (GB)
Title: Manufacture of a new alkaloid and its salts
IPC: C07D459/00
Filed: 1953-07-23
Abstract: The invention comprises the new alkaloid reserpine and its salts, and the preparation thereof by known methods from the extract having a sedative effect obtained by treating Rauwolfia sp. with a weakly polar or non-polar solvent which is immiscible or only partially miscible with water.  The isolation is preferably effected by adsorption on a suitable agent followed by dissolution, e.g. chromatography over alumina, silica or a silicate, elution with a solvent containing benzene and crystallization from an alcohol or a ketone, especially methanol. The initial extract may be obtained from R. serpentina Benth., R. vomitoria Afz. or R. inebrians, preferably the roots thereof. The solvent used is preferably a halogenated hydrocarbon, mixed with a polar solvent such as an alcohol and, if desired, water. (The latter may contain acids, bases or salts.)  The addition of the water causes separation into two phases and the extracted compounds are thereby distributed between a mixture of water and polar solvent on one hand and the weakly or non-polar solvent on the other.  Such distribution is preferably effected over several separation stages.  As an alternative the plant material (or extract thereof) is treated with aqueous acid and the extract so obtained contacted with the weakly or non-polar solvent.  Suitable acids are the phosphoric acids, lower fatty acids and acid salts of polybasic acids.  As a step in any of the above processes the solvent-free extract may be mixed with diatomaceous earth or other carrier and subsequently extracted therefrom; the reserpine is preferably in the form of a difficultly soluble salt such as the hydrochloride or nitrate.  Examples are given of the various ways of carrying out the extraction to yield crystalline reserpine. Salts may be obtained by direct addition of acid or by double decomposition, the preparation of the hydrochloride, nitrate, sulphate, picrate, perchlorate, methanesulphonate, oxalate, salicylate, ascorbate, citrate, malate, succinate and tartrate being described.  Salts may also be obtained with hydrohalic, phosphoric, acetic, propionic, lactic, ethanesulphonic, isothionic, benzoic, p-aminosalicylic and toluenesulphonic acids. The physical, chemical and physiological properties of reserpine are mentioned.

Abstract: 1502332 Buckles K HATTORI 15 May 1975 20550/75 Headings E2A and E2B Buckles are constructed of three sections, a frame surrounding a rectangular aperture, a tongue shaped to fit the aperture and a flexible connector. Straps or belts are fastened by passing them around the tongue which is then folded over and inserted in the aperture. In this position the tongue is flush with the frame. Two embodiments are disclosed. In the single tongue version illustrated in Figs. 8 and 14, one end of the belt 25 is permanently attached to the buckle, the free end being passed around the article to be secured and wedged in aperture 28 between tongue 27 and frame 24. Tongue 27 is made to fit aperture 28 closely in the longitudinal direction, with sloping sides 32 and 33 matching the contours of sloping walls 29 of the aperture and flat surfaces 34 and 35 able to fit flat surfaces 31 and 30 respectively. In the direction transverse to the tongue 27 (longitudinal to belt 25) small clearances of widths approximately those required to enable the belt wrapped around the tongue to lie flush with the frame are provided, by making the tongue slightly narrower and shallower than the aperture and by providing recesses in the base and side of it. Fig. 1 illustrates a double-tongued version operating similarly, but withthe belt having two free ends, one of which will be held by tongue 4 and the other by tongue 41.

Title: Improvements in machines for printing webs of material
IPC: B41F35/00
Filed: 1948-08-04
Abstract: 668,529. Printing-machines; feeding webs. DUNGLER, J. Aug. 4, 1948 [Aug. 11, 1947], No. 20600/48. Classes 100 (i) and 100 (ii). [Also in Group XXX] In a machine for printing web material such as cloth or paper the web is carried by and caused to adhere to a transversely and longitudinally guided flexible but inextensible support attached to rollers' running on laterally adjustable guides whereby it may be tensioned transversely. As shown in Fig. 1 cloth from a trolley 13 passes through a bar tensioner 14 and selvedge guides 15 to a pasting roll 26; thence it is applied to an endless band 18 whose lower run passes between the hydraulically, mechanically or magnetically loaded impression cylinders 5 and the engraved printing cylinders 6 of printing couples 4, 3, 2; the cloth and the band 18 are then separated, the cloth being drawn through a drier B by a device 33 and passed by a folder 34 to a trolley 35, and the band 18 being cleaned and dried by a device 25. Each printing couple 2, 3, 4 may be adjusted transversely and longitudinally by means 7, 8 individually coupled to a continuously driven pulley 9 under control of push buttons 23a within reach of an operator inspecting the printed cloth as it emerges. A drier with blowing nozzles similar to B, or with electric or gas lamps or infra-red heaters may be placed immediately after each couple 4, 3, 2; in other forms printing couples are additionally or alternatively arranged on the upper run of the band 18, the printing cylinders 6 either being indirectly inked instead of themselves dipping into colour troughs 6a as shown, or being replaced by internally-inked screen cylinders; Fig. 9 shows printing cylinders 50, 49 coacting with common impression cylinders 48 of diameter equal or not to that of the end rolls of the band 18. The paste may be applied to the band 18 instead of to the cloth. Feeding webs.-The band 18, e.g. of metal covered with rubberized fabric or of thick cloth impregnated with rubber or with a syntheticresinous material, is driven by a fixed-pivot roller 20, longitudinally tensioned by a roller 19 whose bearings are adjustable in slides 24, and laterally tensioned by the means shown in Fig. 4 comprising endless chains 37 clamped by jaws 36 to both edges of the band, passing over sprockets on the shafts of the rollers 19, 20, and having vertical rollers 38 and horizontal rollers 39 running on rails 40, 41 of which one pair is mounted on projections 51, 51<SP>1</SP> threaded onto shafts 52, 52<SP>1</SP> rotatable by interconnected worm gearing. The Specification as open to inspection under Sect. 91 comprises also an equalizing tenter replacing the lateral tensioning device of the band 18. This subject-matter does not appear in the Specification as accepted.

Title: Aerial array
Inventor: DAVIDSON IAN ARTHUR
IPC: H01Q5/48
Filed: 1954-07-16
Abstract: 757,766. Aerials. BELLING & LEE, Ltd. May 20, 1955 [July 16, 1954], No. 20808/64. Class 40 (7). An aerial array for vertically polarized signals comprises two upper rod elements 10 and 11, parallel to one another and connected at their lower ends by a transmission line element 12. The two elements lie in a common vertical plane and element 11 makes an acute angle with the element 12 as shown. Parallel to the line element 12 there is provided a second transmission line element 13 coupled at one end to a lower rod element 18 extending in the common vertical plane and forming, in association with element 10, an open V aerial. At the other end of element 13 to rod element 18 are connected a further pair of lower rod elements 20 and 21 disposed symmetrically on opposite sides of the common vertical plane to form a V and also forming a V with the element 11 pointing in the same direction as the V of elements 10 and 18 as shown. Connections between the line elements and the rod elements may be made at insulators 14 and 15. A further insulator 16 mounted on the transmission line close to the centre of gravity of the array serves as a mounting whereby the aerial can be supported on a vertical mast 17. The rod elements and the transmission line may all be of the same length while the angle between the rod elements and horizontal may be 45 degrees. If the angular separation of the rod elements 20 and 21 is 30 to 45 degrees adequate separation between them and the mast 17 is obtained. To feed the array a transmission line may be led up the mast and along inside part of the line element 13 to insulator 14 where its conductors are coupled respectively to the upper and lower sets of elements. The spacing and diameter of the line elements may be made such as to effect satisfactory matching per se or additional matching stubs can be provided. The array is stated to be highly directive in the direction of the divergence of the V 10 and 18, and, if the elements are four feet long, to be capable of handling signals of the order of 60 and also between 174 and 216 megacycles per second.
