Title: Method of producing organic boron compounds
Inventor: JENKNER HERBERT
IPC: C07F7/12
Filed: 1960-11-09
Abstract: Organosilicon halides are formed simultaneously with organic boron compounds by reacting a boron-halogen compound with an organosilicon-hydrogen compound in the presence of an unsaturated organic compound.  The organo-silicon-hydrogen compounds include mono-, di- or tri-organosilicon -tri, di- or monohydrides, preferably alkyl silanes with one to four carbon atoms in the alkyl groups, e.g. mono-, di and triethyl silane, mono and dipropylsilane, monobutylsilane and aryl silanes such as monophenyl silane.  The boron-halogen compounds are boron trihalides, diorganoboron halides, organoboron dihalides or organic addition compounds, such as etherates or aminates, of boron halides.  In examples triethyl chlorosilane is obtained from boron trichloride, triethylsilane and (1) cyclohexene, (2) 1,5-hexadiene, and (3) phenylacetylene.  The reaction is performed at temperatures between 40 DEG  and 140 DEG C. The organosilicon halides can be converted to the hydrides by reaction with an alkali hydride activated by an organic boron or aluminium compound as in Specification 823,483.ALSO:An organic boron compound is made by reacting a boron halogen compound with a silicon hydrogen compound in the presence of an unsaturated organic compound. The silicon halide formed simultaneously with the organic boron compound may be reacted with an alkali hydride activated by an organic boron or aluminium compound as described in Specification 823,483, and the silicon-hydrogen compound so formed recycled for reaction with the boron halogen compound and unsaturated compound. The silicon-hydrogen compounds used have at least one hydrogen atom attached to silicon, such as silanes, SiH4, SiH2Cl2, alkyl silanes with one to four carbon atoms in the alkyl groups, or aryl silanes. The term "boron-halogen compound" denotes compounds containing at least one boron-halogen bond, e.g. boron trihalides, diorgano-boron halides, organoboron dihalides, and addition compounds of boron halide such as etherates or aminates.  The unsaturated compounds include linear and cyclic olefines with one or more double bonds of compounds with carbon-carbon triple bonds, which may be substituted with chlorine.  The reaction is preferably performed in an atmosphere of protective gas, e.g. nitrogen, at temperatures between 40 DEG C. and 140 DEG C., at normal or elevated pressure. Solvents, such as ether or hexane, may be used if the product is a solid.  Examples describe the reaction of boron trichloride and triethyl silane with (1) cyclohexene giving boron tricyclohexyl; (2) 1,5-hexadiene to give <FORM:0901622/IV (b)/1> which can be oxidized and hydrolysed to 1,5-hexane diol, or compounds of formulate (C6H12BH)2 and C6H12BCl; (3) phenyl acetylene and (4) acetylene giving organic boron compounds; in Example (5) monosilane, ethylene and boron trichloride yield boron triethyl.

Class 97(1) To make the interference band of zero order more visible against adjacent fringes in an interferometer using white light, in the ray path is placed a filter of such spectral transmission that the product of the spectral energy of the light source, the spectral sensitivity of the receiver and the spectral transmission of the filter for each wavelength in as wide a range of wavelengths as possible is at least approximately independent of the wavelength of the light. Thus where the receiver is the human eye the filter reduces the intensity of the light in the middle range of the visible spectrum and where the receiver is blue or red sensitive such as a photographic emulsion or a thermo-element light of these wavelengths is reduced. Fig. 1 shows an interferometer for determining the concentration of a gas in which the interference fringes are focused by a lens 9 on a scale 10 viewed through an eyepiece 15, an appropriate filter 21, such as an absorption or interference filter, being located before the light source 1.

Abstract: 833,687. Travelling-wave tubes. STANDARD TELEPHONES & CABLES Ltd. Dec. 28, 1956 [Dec. 30, 1955], No. 39447/56. Class 39(1). [Also in Group XL(b)] The delay line of a travelling wave tube consists solely of a stack of laminations forming a hollow waveguide loaded with inter-digitated elements and the laminations are supported and aligned by means of two or more rods 6 passing through apertures in the corners of the laminations. The support rods pass through holes in magnetic shield 8 Fig. 1, and plate 9 to secure plate 9, which holds the gun via three ceramic rods 10 to shield 8, while the other ends of the rods extend into magnetic shield 11 on which is supported the molybdenum collector 12, slanted to reduce secondary emission. The laminations are rectangular and comprise three different shapes arranged consecutively, A, Fig. 2, having a long and a short projection 24a, 29 respectively, B having two short projections 25, 26, C having a short and a long projection 28, 24 respectively, the long projections having apertures 27 for passage of the electron beam. Input and output waveguides are connected by tapered ridges 14, 17 to the delay line, the ridges being connected to extensions of the laminations and a second lamination 5c being connected to the opposite wall of the output guide to improve the impedance match. The laminations are formed by stamping, and the envelope 1 is of metal (or possibly of dielectric material). The beam is focused by a permanent or electromagnet 19 in which it is held in correct spaced relation by pole piece 20. Due to imperfections in the stamping equipment, the laminations may be stamped out as parallelograms but this can be corrected if the laminations of group A are reversed end for end with respect to the laminations of group C.

Abstract: 1,044,918. Removal of dust generated in industrial processes. T. A. GARDNER. Oct. 8, 1963 [Aug. 19, 1963], No. 39592/63. Heading F4X. Means for removing dust &c. from a web of paper, foil or plastic produced in an industrial process comprises a primary air nozzle 12 having an elongated orifice directed toward the web surface, the ratio of the orifice width to its spacing from the web being within the range of 0.02 to 1 and 0.15 to 1, means for supplying air under pressure to the nozzle and means for collecting from the vicinity of the web surface a portion of the air discharged from the nozzle at a speed of at least 10,000 f.p.m. and such dust as is dislodged and carried thereby from the surface of the web. In one arrangement, a housing (6) (Figs. 1 to 3, not shown), contains a plenum chamber (8) supplied with air through a duct (10) for discharge through the primary nozzle 12 and a secondary nozzle 14. The jets of air supplied to the moving web 60 extend across the full width of the web, one jet being perpendicular to the surface and the other inclined inwards towards the first on its upstream side, preferably at an angle of 5 to 25 degrees and with an orifice size of between 50 and 100% of the first. An exhaust chamber 36 has one or more ducts (40) extending from it and opens into filter plenum (46) completing a circuit after filtration through a fan (54) which supplies the air to the nozzles. The two air jets cause disturbance of the air on the surface of the web which leads to the dislodging of dust on the web surface and its conveyance within the air to the filter plenum. Instead of the secondary nozzle, the casing wall may be extended to just above the web in the position of this nozzle, and by being curved to lie substantially parallel to the web (Fig. 7, not shown) can still entrap air in the exhaust chamber 36. Alternatively, a brush attached to the wall may lightly brush the web surface, still permitting no air escape from the chamber 36 or a circular brush on the inside of this wall may perform the same function. In another embodiment, the dust on the web surface may be given an electrostatic charge by a plate (98) (Fig. 10, not shown), whilst the action of similarly charged plate (100) and the oppositely charged electrode (102) will cause the repelling of the charged dust from the web into the air stream.
