Title: Improvements in and relating to glass tube bending apparatus
IPC: B29B13/02
Filed: 1947-03-27
Abstract: 622,563. Bending glass tubes. BRITISH THOMSON-HOUSTON CO., Ltd. March 27, 1947, No. 8350. Convention date, March 30, 1946. [Class 56] A glass tube is sharply bent into U-form, e.g. to provide an envelope for an electric discharge device such as a germicidal lamp, by holding the tube in means which are swung simultaneously towards one another to bend the previously heated middle zone of the tube around an abutment pin. As shown, the tube 10 is gripped between horizontally directed V-notches in plates 36 and spring-pressed clamps 38. The plates 36 and clamps 38 are carried on pivoted arms 1 which initially are in horizontal alignment. The abutment pin 9 is concentric with a stud 4 on which the arms are pivoted, and the plates are so arranged that the tube 10 lies initially beneath the level of the pivot so that the pin 9 may be projected against spring pressure, by a treadle 15 and linkage 16, 17, 20, to lie above the tube. In operation, the middle zone of the tube is heated by burners 39 which are swung horizontally away from the tube when bending is to be effected. The pin 9 is then projected and a treadle 30 connected, by a pulley cord 31, sliding rod 26 and levers 29, to pins on the arms 1, is depressed to swing the arms upwardly towards one another, the pins moving along arcuate slots 23 formed in the supporting framework 2. The tube 10, when it is to be used as an electric discharge device, has outwardly extending exhaust tubes 34, 35, the latter being tipped off. To prevent the tube from collapsing at the heated region, air or other gas is introduced under slight pressure through the exhaust tube 34, a rubber tube 43 being connected to the exhaust tube 34 and either provided with a mouthpiece 44 or with a connection to a supply of compressed air. The pin 9 serves to round out the inner side of the bend 45 and to obviate buckling or corrugating at the sharp bend.

Title: Improvements in or relating to the production of substituted tetrahydro-1,4-oxazines
Filed: 1959-03-11
Abstract: The invention comprises 2-phenyl-4-benzyl-, 2 - methyl - 3 - phenyl - 4 - benzyl -, 2 - (p - chlorophenyl) - 4 - benzyl -, 2 - phenyl - 3 - benzyl - 4 - methyl -, 2 - (5,6,7,8 - tetrahydronaphthyl - 2) - 3,4 - dimethyl -, and 2 - (m - hydroxyphenyl) - 3 - methyl -, 1,4 - oxazines, 2 - (p - methoxyphenyl) - 3 - methylmorpholine and their acid addition salts.  In general tetrahydro-1,4-oxazines of the general formula <FORM:0862198/IV (b)/1> are produced by heating an a -(ethanolamino)-ketone of general formula <FORM:0862198/IV (b)/2> or a salt thereof with formic acid or a compound yielding formic acid under the reaction conditions, R1 being alkyl, aryl or aralkyl and R2, R3, R4 and R5 representing hydrogen or alkyl, aryl or aralkyl residues, and in which R1, R2, R3, R4 and R5 may be the same or different and may be substituted.  The process is particularly useful for the production of those compounds in which R1 is a methyl, phenyl, chlorophenyl, methoxyphenyl, hydroxyphenyl or tetrahydronaphthyl radical and R2, R3, R4 and R5 are hydrogen atoms or methyl, phenyl or benzyl radicals.  Substances yielding formic acid under the reaction conditions are, for example, formamide or dimethylformamide.  The process may be carried out in a solvent medium, e.g. 70-100% aqueous formic acid; an amide such as acetamide, dimethylformamide or dimethylacetamide; a urea derivative such as N,N1-dimethylurea; or an amine such as aniline, dimethylaniline, benzylamine or pyridine.  The preferred temperature range for the process is 130-140 DEG C.  It is advantageous to add an esterification catalyst such as, for example, perchloric acid, trichloracetic acid, p-toluene sulphonic acid, strongly acidic ion-exchangers, zinc chloride or boron trifluoride.  If in the product R3 is a benzyl group or if any of the groups R2, R4 or R5 is a benzyloxy-phenyl residue these may be catalytically hydrogenated to replace the benzyl groups by hydrogen.  Specification 791,416 is referred to.

Title: Improvements in means for controlling the speed of a record in the form of a film, band, strip or the like for the recording and reproduction of sound
Filed: 1928-03-21
Abstract: 314,001. British Acoustic Films, Ltd., and Metcalfe, J. March 21, 1928. Feeding webs.-Relates to apparatus for driving at a constantspeed a film, band, or the like for recording or reproducing sound, such apparatus being of the kind described in Specification 249,627, in which the film &c. as it is fed forward drives a fly-wheel. According to the invention. the fly-wheel is initially set in motion by a. driving-member acting through a freewheel device. As shown, the fly-wheel 1 carries a roller 6 over which the film passes, and on its shaft 2, or otherwise connected to the fly-wheel, is a disc 5. A wheel 7, rotated by the driving motor of the sound-recording or reproducing apparatus, has pivoted thereto two or more spring-actuated pawls 9, frictionally engaging the edge of the disc 5. On starting the machine, the wheel 7 drives the fly-wheel, through the freewheel device 9, 5, and the gear ratio is such that the maximum speed of the wheel 7 is slightly less than that at which the fly-wheel is rotated by the passage of the film over the roller 6. Therefore, after the fly-wheel has thus been started, the disc 5 slips under the pawls 9 whilst the fly-wheel is being driven by the film.

Filed: 1923-04-03
Abstract: 195,646. Kapferer, H., and Kapferer, M. April 1, 1922, [Convention date]. Wheels and axles, arrangement of.-A vehicle axle carrying swivelling wheels is, by means of a pivoted sprag, automatically given a partial rotation about its longitudinal axis so that the axes about which the wheels swivel are inclined to a vertical plane containing the axle and in a direction which meets the road at points in advance of the points, of contact of the wheels whether the vehicle is travelling forwardly or rearwardly. The axle 1, having forks 2 carrying swivelling members 3, is mounted in bearings 6, and a shaft 7 mounted parallel to the axle in bearings 8 carries a sprag 9 provided with a spring-controlled end 10 and a pin 12 which engages a fork 13 on the axle 1. When the axle moves in the direction of the arrow in Fig. 2, the, engagement of the pin 12 with the fork 13 causes the swivelling axes to incline in the direction shown by the dotted line 14. If the axle is moved in the reverse direction, the sprag 9 swings underneath the axle to the opposite side thereof and causes the swivelling axes to incline in the opposite direction. The slot 12 and fork 13 may be replaced by any suitable devices to obtain the necessary rotation of the axle 1. In a modification, the swivelling axes are vertical when the axles moves forwardly, the forks 2 being bent so as to bring these axes in front of a vertical plane passing through the points of contact of the wheels with the road, but when the axle moves in the reverse direction, the sprag causes the swivelling axes to incline in the required direction to effect the trailing action of the wheels. Specification 175,980 is referred to.
