Abstract: 679,625. Joining pipes to headers BABCOCK & WILCOX, Ltd., and WEBB, T. B. June 7, 1950 [June 7, 1949], No. 15162/49. Class 99 (i). [Also in Group XXII] Each of a plurality of stub tubes is united to the wall of a pressure vessel by a fusion weld the root metal of which is removed, each of said stub tubes communicating with the interior of the vessel through an orifice formed in the metal of the vessel and of substantially smaller diameter than the bore of the stub tube. Preferably the pressure vessel serves as a distributer for distributing fluid under pressure to a bank of tubes e.g. in a heat exchange such as an economizer, boiler or superheater at least some of said tubes including a main part welded to one of the stub tubes, Fig. 1 (not shown). In Fig. 2 after the stub 21 has been fusion welded to the wall 3 of the pressure vessel (Fig. 2a) an axial bore 23 in the stub is extended and continued for a short distance into the vessel wall (Fig. 2b). Thereafter a hole 33 of smaller diameter than the bore 23 and constituting the orifice, is drilled through to the interior of the vessel. In Fig. 3 the stub is provided initially with a short spigot 43 which is located in a hole 45 in the vessel wall (Fig 3a). After welding, the bore of the stub is continued into the vessel wall (Fig. 3b), the boring operation resulting in the removal of the spigot. In Fig. 4, the stub is provided with a throughbore and with a short annular flange 57 which is fitted into a shallow recess 59 in the vessel wall (Fig. 4a). After welding, the stub bore is enlarged to remove the flange 57 and this bore is continued into the vessel wall (Fig. 4b), a hole 63 forming the orifice being drilled in the vessel wall either before or after the stub is welded to the vessel.

Title: Improvements in or relating to coal carbonization and gasification
IPC: C10B51/00
Filed: 1948-06-07
Abstract: 646,105. Gas-manufacture. HYDROCARBON RESEARCH, Inc. June 7, 1948, No. 15298. Convention date, June 11, 1947. [Class 51 (i)] In the carbonization and gasification of solid carbonaceous material, the gasificatiori is effected exothermically in the chamber 11, and the fresh material, in pulverulent form, is carbonized, by indirect heatexchange with the mass being gasified, in the pipe 19 in which it is entrained in a non-oxidizing gas and delivered to a gassolids separator 21, the coke being delivered to the mass being gasified and the distillation gases being withdrawn through the line 23. The gaseous products of gasification are separately withdrawn through the pipe 25. The non-oxidizing gas, supplied through the pipe 15, may be re-cycle gas; and coke, withdrawn through a pipe 14 and kept in free-flowing condition by a steam supply 14a, may be re-cycled with the gas to prevent agglomeration of the coal in the pipe 19. The coke in the chamber 11 is fluidized by gases, i.e. hydrogen or oxygen-containing gas with or without carbon-dioxide and/or steam, from the pipe 16 and, in cases where excess heat is generated, this is utilized for cracking oil introduced through the pipe 28, or for steam-generation in the coil 27. Coke is withdrawn through the pipe 26. The pipe 19 may be in spiral form, or may be replaced by a series of tubes. The enlarged section 13 of the chamber 11 results in a reduced gas velocity in the upper part of the chamber and reduces the risk of entraining large particles from the mass.

Title: Improvements in photographic recording and reproduction of sound
IPC: G11B7/00
Filed: 1928-05-25
Abstract: 291,105. Westinghouse Electric & Manufacturing Co., (Assignees of Zworykin, V. K.). May 26, 1927, [Convention date]. Optical apparatus.-In apparatus for photngraphically recording sound a light is caused to illuminate a moving sensitized surface with a periodioally varying intensity of super audio frequency which is modulated by the sound and the movement of the surface during one complete period of the super audio variation is twice the extent of the illuminated area in the direction of that motion. Less distortion in the record so produced and in the reproduction therefrom is stated to result under this condition, As applied to recording, light from a thin straight filament 1, fig. 1, is projected through a lens 2, nicol prism 3, and Kerr cell consisting of nitrobenzole or other optically active material 4 between electrodes 5, and passes through a nicol prism 6 and lens 7 to form an image of the filament on a moving sensitized strip 8. An electrostatic field is set up between the electrodes 5 by a current of super audio frequency produced by an oscillator 12, which current is modulated by the sounds applied to a microphone 14 and fed to a high frequency valve 13 whose output is amplified by a valve 15 and impressed, through a circuit containing a combination of a coil 16 and a condenser 17 in parallel to furnish a high impedance to the current, on the electrodes 5. The light 1 and the centre of the cell are arranged at conjugate foci of the lens 2 which is selected to produce the desired area of illumination of the strip without using a light slit. The polarizing prism 3 is preferably arranged so that the plane of polarization of the light is approximately at 45‹ with the field of the Kerr cell which is preferably biassed by a battery 18 so that change in intensity of the engaging light shall be approximately proportional to the changes in intensity of the field. The prism & is placed at suitable angle to cut off all light due to a, steady or average value of the field and thus transmits substantially only the light variations corresponding to the sound variations. A suitable supersonic, frequency would be 20,000 when the highest audible frequency to be recorded is 5,000, and the width of the image of the filament 1 on the film 8 should be half of the high frequency wave length on the film. Fig. 2 shows apparatus for reproducing a record made as described wherein light from a filament 20 is directed by a lens 21 through the film record 22 on to a photo electric cell 24 connected through a circuit containing batteries 25 and 27 and a resistance 26 with a high frequency valve 28. The output is delivered to a detector valve 30 the output from which is delivered directly or through one or more low frequency amplifiers 31 to a loud speaker 32 or other sound emitter.

Abstract: 727,594. Drop boxes for looms. BRITISH COTTON INDUSTRY RESEARCH ASSOCIATION. June 17, 1953 [June 19, 1952], No. 15417/52. Class 142 (2). The movement of drop. boxes is obtained from the rotation of the picking shaft through gears and interlocking discs so that the drop boxes are in their uppermost or lowermost position for two picks. The picking shaft 10 carries a disc 24 having a gear segment 25. The segment 25 engages a gear 30 on a countershaft 19 carrying a crank pin 32 and a rod 33 connected to the drop box 17. Each rotation of the shaft 10 turns the pin 32 through 180 degrees. The shaft 19 is locked against unintentional rotation by notches 29a engaging the edge of the disc 24 ; a notch 26 in the disc 24 allows the discs to turn when the gears 25, 30 engage. A bracket 13 enclosing the picking cam 12 and the bottom of the picking stick 14 has bosses 20, 22 to which the disc 24 and a bracket 18 carrying the countershaft are secured. In a modification, the bracket 13 is extended to enclose the discs and gears and contains a lubricant. The slay swords 15 are bolted to the bracket 13. If a dog-clutch or a sliding key, controlled by a selector mechanism is introduced between the shaft 19 and members 31, 32 other picking arrangements may be obtained. Further picking arrangements may be obtained by duplicating the drop-box and clutch mechanism at the other side of the loom. Specification 690,620 is referred to.

Title: Process for covering carriers with bituminous substances, and products manufactured according to this process
IPC: D21H17/61
Filed: 1929-05-17
Abstract: 312,909. Elkington, H. D., (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). June 2, 1928, [Convention date]. Paper, treating with special materials.-In a process for covering a carrier with bituminous substances applied as an emulsion, for example, in the manufacture of asphalt paper, in order that the product may be moisture proof as well as waterproof the viscosity of the bituminous substance is reduced during some stage of the manufacture below 750 sec. according to the Redwood II test. A bituminous substance having a sufficiently low viscosity at the temperature (80‹- 120‹ C.) employed during manufacture may be selected, or the paper may be heated to 120‹- 150‹ C. or even to 250‹ C. The temperature limit is that at which the cellulose decomposes. The time of heating varies from under 1 min. at the highest temperatures to over 10 mins. at lower temperatures. The heating may be carried out in the absence of air or other gases which tend to oxidise the cellulose. The viscosity may be further reduced by the addition of substances such as paraffin wax, resin or naphthalene. The heating may be effected during calendering of the paper and the process is particularly adapted for the manufacture of paper in which the bituminous composition is secured to the paper-fibre mass by resin-glue and alum. In examples, a Mexican asphalt of viscosity 2000 secs. at 100‹ C. is used and the paper heated to 150‹ C. ; with an asphalt of viscosity 40 secs. at 100‹ C., the paper is heated only to that temperature; and an asphalt of viscosity 2000 secs. at 100‹ C. is mixed with 10 per cent hard paraffin wax, reducing the viscosity to 1200 secs., and the paper is heated to 130‹ C.

June 8, 1943, Nos. 15622/45, divided out of 9210/43, and 15623/45, divided out of 6286/44. [Class 40 (iii)] [Also in Group XXVII] In a duct, such as a ventilatory shaft, an arrangement for absorbing sound waves of frequencies approximating to two predetermined values comprises a laminal enclosure which may contain a layer of porous material, formed by a pair of dissimilar imperforate vibratory sheets spaced apart by a distance such that the acoustic impedance of the layer of contained air or porous material at the location of the inner surface of each sheet provides a stiffness reactance high relative to the resistive component of the normal impedance at the said location. The vibratory sheets have mass distributions such that for one of the predetermined, frequencies one of the sheets has a mass reactance to balance the stiffness reactance at that frequency, whilst the mass reactance of the other sheet is similarly matched at the second frequency. In effect the laminal enclosure is unaymmetrical and is constructed to have two resonant frequencies corresponding to the frequencies to be absorbed. The acoustic resistance of the enclosure together with the acoustic resistance of either vibratory sheet is of the same order of magnitude as the .characteristic impedance of the air or other medium in the duct. The static pressure within the laminal enclosure may be less than that of the air or other medium in the duct. A number ' of laminal enclosures may(be arranged side by side or in tandem with their general planes extending substantially parallel with the longitudinal axis of the duct. Specification 590,541, [Group XXXVIII], is referred to.
Patent GB-1036906-A (GB)
Title: Resinous moulding composition
Inventor: ADOLPH COLIN WILLIAM
IPC: C08L61/20
Filed: 1963-04-19
Abstract: A moulding composition comprises an amineformaldehyde-cycloaliphatic ketone resin and a filler.  The preferred components of the resin are amine: melamine, urea, or benzoguanamine; ketone: cyclohexanone or an alkyl-cyclohexanone. A melamine-formaldehyde-cyclo-hexanone resin is particularly preferred.  The ratio of amine to keto groups is preferably not less than 2:1.  The resin is suitably prepared by adding the amine to an alkaline or slightly acid aqueous solution of the ketone and formaldehyde previously condensed in alkaline solution.  The solution may then be compounded with the filler, with or without e.g. a catalyst, lubricants, or pigments, and hot-milled, cooled and ground.  In examples, a melamine-cyclohexanone-formaldehyde is mixed with cotton linters, dried, mixed with chloracetamide and cadmium stearate, milled, and moulded. Phosphoric acid may be added after the melamine.

Filed: 1946-05-24
Abstract: 614,452. Hydraulic brakes. HYDRAULIC BRAKE CO. May 24, 1946, No. 15871. Convention date, June 1, 1945. [Class 103 (i)] A hydraulic master cylinder suitable for operating vehicle brakes comprises a plunger 14 carrying a pedal member 49 and extending through a fixed partition 13 which divides the cylinder 1 into chambers A, B, connected respectively at 34 to the pipe-lines and by an opening 41 to a reservoir 40. The chambers are connected together when the plunger is in the normal position shown, by passages 42, 43 in the partition and plunger, the passages becoming out of register with each other as soon as the stroke of the plunger begins. During the return stroke liquid flows through passages 45 in the partition and past the cup washer 16 from chamber B to chamber A if the pressure in chamber A tends to fall. Rotation of the plunger is prevented by a rod 50 slidable in a tubular member 4 which is secured to the cylinder 1 by a band 5 and by the member 2 by which the device is bolted to the vehicle floorboard. A return spring 52 acts on the rod 50 and this rod is lubricated by liquid which escapes from the cylinder 1 and flows through a passage 57. A light pressure is normally maintained in the pipe-line by a ball-valve 32 urged to seat on a rubber ring 26 by a spring 33, return flow from the pipe-line being permitted by unseating of the ring from the end of the cylinder against the action of a spring 28 which is stronger than the spring 33.

Title: Apparatus for determining the weight of railway vehicles
IPC: G01G19/04
Filed: 1960-05-05
Abstract: 926,985. Weighing-apparatus. SIEMENS & HALSKE A.G. May 5, 1960 [May 29, 1959], No. 15954/60. Class 40 (1). [Also in Group XXXVI] The weight of railway vehicles is measured in terms of the rail deflection caused by the pressure of the wheels, using two or more detectors spaced along the track and determining the difference between the measurement values given by the detectors. This method avoids errors due to yielding of the ballast under the sleepers (whether uniform or not) and the effect of an adjacent wheel. In Fig. 1, two strain-gauge detectors G1 and G2 are fixed to a rail between adjacent sleepers B2 and B3 and are sensitive to deflections produced by adjacent wheels R1 and R2 of a bogie. Two similar detectors g1 and g2 are attached to the opposite rail and each pair is included in an A.C. bridge (Fig. 7) with two fixed resistors, which may be dummy strain-gauges. The bridge outputs are joined in parallel so that the measured voltage represents the mean value of the wheel pressures and the indicated weight will not be incorrect due to asymmetric loading of the vehicle. The bridge is previously calibrated so that in use the output voltage never falls to zero, or alternatively a phase-sensitive demodulator is used. The fixed resistors may be arranged to compensate for temperature variations. Three detectors may be used (G10, G20, G30 in Fig. 1) disposed in two compound bridges (Fig. 8) whose outputs can be combined in any desired way. A fourth detector can be added so that the measured value is held for an appreciable time as the vehicle moves, without the use of storage circuit elements. Extra sensitivity can be obtained by replacing the fixed resistors of the bridges by further detectors arranged to be deflected in the opposite sense. The two pairs of detectors are then secured to a plate mounted on straps beneath the rail (Fig. 10, not shown) instead of to the rail itself. The output of the bridge (Fig. 9) is demodulated at DM and applied to a capacitor C1 through a diode 1, the contacts 11 and 12 being opened by the approach of the first wheel acting on a magnetic impulse generator or an optical system. When the output changes sign, the capacitor C1 discharges through the diode 2 into a smaller capacitor C2, so that the latter assumes a potential equal to the difference between the maximum and minimum peaks of the bridge output, this representing the weight of the vehicle. The contacts may alternatively be operated by a self-holding relay dependent on the output voltage of the demodulator, the relay being subsequently de-energized from the indicator circuit W. The system of Fig. 9 with detectors mounted on straps beneath the rail can be extended to the use of three or four detectors as described above (Figs. 11 and 12, not shown). Measurement may also be effected with a D.C. bridge or with an ohm-meter. The detectors may be piezo-electric or magneto-inductive impulse emitters. The measurements may be based on actual yielding of the rail or on its curvature.
