Title: Device for indicating characters which can be composed of individual elements, particularly for the indication of digits and letters
IPC: G09F9/305
Filed: 1963-07-12
Abstract: 1,041,078. Monogrammic signs. LICENTIA PATENT - VEKWALTUNGS - G.m.b.H. July 12, 1963 [July 12, 1962], No. 27728/63. Heading G5C. Any one of a series of characters (letters or digits) is formed by the selective illumination of individual elements a . . . g (Fig. 1, not shown), each element being formed by one end of a light conducting body whose other end is divided into component fields, equal in number to the alternative characters to be indicated, so that illumination of a specific combination of component fields causes the device to indicate a specific character. Fig. 2 shows how prismatic bodies, corresponding to elements a ... g extend from the indicating plane (Fig. 1) to the illuminating plane A-B. The bodies of elements c, d, e are twisted helically and in the illuminating plane the ends of the bodies are arranged in rows (Fig. 3, not shown), each row corresponding to a character, in the example the numerals 0 . . . 9. Each row is illuminated at will by its own fluorescent tube, strip light or set of lamps extending along it. A mask (Fig. 3) prevents elements not required in a particular character being illuminated, e.g. the numeral " 9 " is indicated by illuminating row 9 in Fig. 3, in which the body corresponding to element a is covered. The prismatic bodies are either of solid plastic or hollow with internal mirror coatings. Each character may be indicated in one of several different colours by using several coloured lights selectively illuminating each row. The device may be used for advertising, indicating, e.g. hymn numbers, to bodies of people, or traffic control.

Title: A process for the production of ªÐ-cymene from monocyclic terpenes
IPC: C07C5/46
Filed: 1923-11-08
Abstract: Monocyclic terpenes are dehydroganized for the production of p-cymene by heating with sulphur and one of the organic base catalysts used in the rubber industry as vulcanization accelerators, such as thiocarbanilide or di- or tri-phenylguanidine; the cymene is isolated by steam-distillation, whilst the residue, a sulphur-containing resinous mass of balsamic odour, can be used for therapeutic purposes.  In an example, dipentene is heated with sulphur and thiocarbanilide, the product steam-distilled and the distillate purified by treating with permanganate solution and again steam-distilling; it can be still further purified by distilling over metallic calcium.  Other terpenes mentioned are terpinolene and terpinene.

Abstract: 1348227 Mixing liquids in proportions BOEHRINGER MANNHEIM GmbH 16 June 1972 [18 June 1971] 28228/72 Heading B1C [Also in Divisions B8 and F2]  In a method and apparatus for metering a liquid additive into a flowing liquid without causing flow rate fluctuations, the main flow is supplied to two pipes ZZ1, ZA1 and ZZ2, ZA2 connected in parallel and interrupted by a valve member AS having a flow passage VDI and a metering passage VD2. As shown in Fig 2b the metering passage is being filled by a vacuum previously built up in the chamber VK while the main flow passes through ZZ1, VD1, ZA1. In a subsequent position, of the valve member, Fig. 2c, the flow through ZZI, ZA1 is interrupted and flow takes place through ZZ2, VD2, ZA2, the additive being swept out into the main flow and mixed in a column (S, Fig. 1, not shown) without disturbance of the flow rate. At the same time the additive inlet FFZ and vacuum chamber VK are purged by connection to the vaccum pipe KVL. Subsequently the metering passage is also purged by connection between the air inlet LZ and vacuum pipe VA, see Fig. 2d, not shown. The metering apparatus may be embodied as a rotary valve, see Figs. 3-9, not shown, which may be rotated manually or by motor in a constant sense to perform successive metering operations; it may be controlled by a timing device.

Filed: 1925-11-10
Abstract: 250,485. Standard Telephones & Cables, Ltd., (Bell Telephone Laboratories, Inc.). Nov. 10, 1925. Vacuum tubes. - A grid for use with a cathode having a thermionically active coating comprises a material capable both of combining with particles from the cathode to form a non-emitting compound and of fixing gases evolved from the cathode. Aluminium may be employed for this purpose, either alloyed with the metal of the grid or applied as a covering, preferably in admixture with alumina in the form of a " calorized " coating. One or more grids of nickel, iron, nickelchromium, &c., may be embedded in a mixture of powdered fused alumina and powdered aluminium in a nickel box, preferably after preliminary heating to remove oxides and occluded gases. The box, with the grids, is then placed in an electric furnace and, after being exposed to a current of hydrogen, is heated to 850‹ C. for 1¢ hours. The coating thus obtained is non-porous but can absorb gases, and prevents secondary electron emission. In the thermionic valve shown, the filament 17, which is coated with an alkaline earth, is supported by resilient wires 19 - - 22, the wires at the lower end being mounted in a glass stem 13, and those at the upper end being attached to an arbor 14 supported by the stem. From the arbor are also supported the wire grid 16 and the anode 15, which is a flattened cylinder. Specification 228,760 is referred to.

Oct. 13, 1931, No. 28474. Convention date, Feb. 16. [Class 30.] In a combined razor and sharpening device, the blade and blade support are adapted to be moved away from the guard and sharpener to facilitate turning the blade about its longitudinal axis and an axis perpendicular thereto, so that either face of the blade edge, or edges, can be presented to the sharpener without removing the blade from its support. The sharpener comprises a helically ribbed roller 17 adapted to be rolled over the hand of the user. The.blade 15 is carried by clamping members 21, 23, the latter being pivoted about a longitudinal axis through the centre of the blade on a stirrup 25, riveted to a handle plunger which can be pushed from its end 29 against pressure of a spring 28 to lift the blade above the guard 13 and the roller 17, as shown in Fig. 4, so that by rotation of the end 29 of the plunger a different edge can be brought over the roller, or by also rotating the blade on its longitudinal axis the opposite face of the same edge can be so positioned. The blade is located in the clamping members by pins 22 on the lower member 23 and the pins may, as shown, be headed so as to clamp the upper member 21 bayonet-wise. Alternatively the pins may be plain and the lower-member carry a rectangular headed stud which passes through a similar aperture in the upper member and is rotated to ride up bevelled edges of the aperture to overlie it and clamp the blade. Finger-pieces 32 carried by the pivot of the lower clamping member 23 facilitate turning over the blade. The guard 13 which has blade spacing lugs 14, is carried, together with the supporting arms 16 of the roller 17, by a plate 12 to which the hollow handle 10 is removably secured. The plate 12 has pins 30 fitting apertures in the stirrup 25 to locate it. The sharpening roller 17 may be mounted in slots in the arms 16 and be pressed by S springs towards the blade. The arms 16 may be longer than the guard support so that the blade is inclined downwards at its shaving side, or this effect may be secured by use of rollers of different diameter.
