Patent GB-937535-A (GB)
Title: Strip feed for strip joining apparatus
Inventor: COOPER JOSEPH HUELETT
IPC: B21D39/03
Filed: 1962-08-18
Abstract: 937,535. Strip feed mechanisms. TAYLOR-WINFIELD CORPORATION. Aug. 18, 1962, No. 31798/62. Class 83 (4). A loading mechanism for strip - joining apparatus comprises a verticallyspaced pair of guide rolls, a reversing drive roll positioned forwardly of and vertically intermediate said guide rolls, upper and lower pressure rolls adapted to clamp strip on to the drive roll, and means to move said pressure rolls selectively into engagement with said drive roll. The device includes a base 10, clamps 11, 12 and a double shear 99, 101. Strip stock from each of two feed reels enters along the paths 95, 96 and is deflected round guide rolls 111 and 112. Intermediate between the guide rolls is a reversible drive roll 116 and on each side of the drive roll is a pressure roller 118, 124 each of which can be moved into pressure engagement with the drive roll by a fluid cylinder 121, 125. A deflector 117 is pivoted about the axis of the drive roll and moves in synchronism with the pressure rollers to move a clamp-bar 131 upwardly or downwardly as required so that no sharp bends or kinks are imparted to the strip. The clamp bar 131 cooperates with upper and lower clamp bars 132 and 134 which can be moved independently into engagement with the centre-bar by fluid cylinders, and the complete assembly of three bars can be moved vertically by fluid cylinders. Operation.-Assuming that strip is running through the apparatus along path 95 the leading end of the next strip from the lower reel is moved between rolls 116 and 124, cylinder 125 is actuated to clamp the strip against roll 116 and the roll is driven to move the strip slightly beyond the first blade of the shear 99, 101. The strip is then clamped between the bars 131 and 134 and the pressure roll 124 is retracted. As the trailing end of the strip moving along the path 95 approaches roll 116, a pair of pinch rolls 126 are stopped and then the double clamp 132, 131, 134, the clamps 11 and 12 and the pressure roll 118 are moved down simultaneously to clamp the strips together and move them down into the lower strip path, and to clamp the upper strip on to roll 116. The shear is actuated, the clamp 11 released and the roll 116 is driven to expel the cropped end of the upper strip. The clamp 11 is then closed again, and moved bodily forward by a fluid cylinder 17 to overlap the ends of the strips for welding by electrodes carried by a transversely movable frame 31.

Title: Method and apparatus for controlling the temperature of exothermic reaction chambers
IPC: B01J19/00
Filed: 1935-11-18
Abstract: <PICT:0467564/III/1> A method of controlling the temperature of catalytic and other exothermic reactions by cooling consists in maintaining a layer of vigorously boiling liquid in contact with the wall of the reaction chamber and regulating the pressure at which the liquid boils.  Thus, the reaction may be carried out in a chamber 1 containing the catalyst and having inlet and outlet pipes 24, 25 respectively for the reacting gases, and cooled by the evaporation of liquid in the annular space between concentric tubes 2, 3. Liquid at boiling point is supplied from a heater 10 to the lower end of the space, and evolved vapour passes down the tube 3 to a condenser 5. The condensate is forced by a pump 6 to a receiver 8 connected to the heater 10 and having an overflow to a trap 13 provided with a pressure gauge and a relief valve and connected to a compressed gas vessel 14.  The pressure in the trap and, therefore, throughout the apparatus is regulated by the valve 16. The trap may, however, be connected to a vacuum pump.  In a modification, the vapour may pass to a condenser 20. Specifications 390,186 and 390,504 are referred to.

Title: Improvements in or connected with internal combustion engines
IPC: F02D1/00
Filed: 1919-12-19
Abstract: 151,190. Bell, W. T., and Douglas, J. T. Dec. 19, 1919. Driving-mechanism.-In an internal-combustion engine the timing of the injection of liquid fuel is adjusted by moving the governor T and the cam F, which actuates the fuel-valve or fuelpump D about the crank-shaft without altering the setting of the governor. The governor casing T carries a bevel wheel X which is driven from a wheel Y on the crank-shaft by a pinion Z. The pinion Z is carried in a hand-wheel Y which can be adjusted about the shaft and clamped in any position. The governor weights are connected by links to a cam F mounted on an eccentric U on the shaft, and the adjustment of the hand-wheel Y turns the cam F about the eccentric and alters the timing and the stroke of the fuel valve or pump. The governor controls the speed by turning the cam F so as to advance the injection and decrease the amount of fuel injected when the speed increases. A ring N adjustable by hand brings cam surfaces P beneath collars on the fuelvalves or pump plungers so as to limit their stroke independently of the action of the governor. Several fuel-valves or pumps may be carried on the frame A surrounding the cam F.

Patent GB-283569-A (GB)
Title: Process for the removal of phenols from tars or tar oils
IPC: C10C1/18
Filed: 1927-11-28
Abstract: 283,569. Karpßti, J., and Hubsch, M. G. Jan. 15, 1927, [Convention date]. Tar oils, purifying.-Tars, tar oils, and other tar derivatives are treated for the removal of phenols by a solvent for phenols diluted with water, the treatment being effected at 100-150‹ C. and at moderate pressure such as 1.5-6 atmospheres; the mixture is then allowed to separate into layers and the aqueous solvent layer is removed, cooled, and released from pressure, whereby the phenols separate from the solvent. The solvents mentioned are methyl, ethyl, and propyl alcohols, acetone, formaldehyde, and acetaldehyde. The alcohol may be of 20 per cent strength. The treatment may be effected in an autoclave provided with a stirrer or continuously in a series of autoclaves and coolers, and instead of using stirrers the two liquids can be introduced in opposite directions. Atomizers, heat exchangers, &c. can be employed and the whole apparatus may be enclosed so as to avoid loss of solvent. When the solvent has been in contact with the tar &c. for a time, the stirring is stopped and the mixture separates into two layers. The aqueous solvent containing the phenols is drawn off and cooled, when it separates into two layers, one being the phenols and the other the aqueous solvent which is used again. The solvents may be made more effective by adding salts such as sodium chloride, sulphate, &c. which reduce the solubility of the hydrocarbons. As the more acid phenols are more readily soluble, the process may be effected fractionally so as to obtain the different phenols separately in succession. The Specification as open to inspection under Sect. 91 (3) (a) describes the process as being effected at moderate temperature and pressure such as 90-150‹ C. and 1.5-6 atmospheres. This subject-matter doee not appear in the Specification as accepted.

Title: Improvements in or relating to pressure indicators or recorders
IPC: G01L7/16
Filed: 1919-12-23
Abstract: 163,742. Thring, L. G. P. Dec. 23, 1919. Indicating, optical devices for.-Apparatus for indicating or recording pressures and producing engine indicator diagrams and particulatly for use with high pressures as in ordnance or internal-combustion engines, comprises a piston D subjected to the explosion pressures and connected by a strut E with a rotatably mounted pointer or a mirror G which may reflect light upon a moving sensitized strip. The piston is formed at the lower end of a tube C secured at its upper end to a coaxial tube B fixed at its lower extremity to a base plate A. More than two coaxial tubes similarly interconnected and mounted may be employed. The mirror G may be carried by a spring strip K adjustably clamped to its supports by screws K<1> after being positioned accurately by means of screws R. Alternatively the mirror may be supported by means of trunnions (Fig. 5) one of which, M, is mounted in a spring blade which exerts pressure upon the bearings to prevent looseness. The strut E may be secured to the arm F of the mirror by a conical-headed screw H traversing a ccnical hole in the strut. In order to produce a pressure-space diagram, the mirror is carried by a table N rotatable upon the base plate A about the axis of the tubes B, C and shifted relatively thereto by connection with a rod S anchored to a stationary member U. When the explosion occurs, a bracket X secured to the breech block or base plate A moves therewith so that relative movement takes place between the base plate A and the table N carrying the mirror, until the bracket X reaches a collar V fixed on the rod S whereupon this relative movement ceases. The effective length of the rod may be varied by adjustment of the screw Y. In order to check initial adjustment and to furnish a datum line on the record surface, a mirror Z may be adjustably mounted on the table N. The latter rests on the base plate by means of steel points 0 and is retained thereon by spring clips P.

Title: Improvements relating to apparatus for controlling the time relationship between different occurrences, especially as applied to apparatus for scanning cinematograph film for the purpose of generating or recording television signals
Inventor: GREENHEAD BERNARD RANDOLF
IPC: H04N3/38
Filed: 1949-01-15
Abstract: 690,487. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 5, 1950 [Jan. 15, 1949], No. 32325/49. Divided out of 690,482, [Sept. 27, 1947], No. 24719/49. Class 40 (iii). In television apparatus in which each frame of a continuously-moving film 8 is successively scanned by the two component frames of an interlaced scanning raster, and in which, as described in Specification 690,482, incorrect interlacing due to film shrinkage or stretching is prevented by the application to the framescanning generator of a compensating squarewave which adjusts the relative positions of the raster components, the shutter which selects the components alternately may, when the apparatus is first set in operation, be 180 degrees out of phase with the square-wave generating circuits so that the adjustments would be made in the wrong directions. According to the present invention, such phase difference is, if present, eliminated. As in the prior case, the raster components are produced by optical systems 29, 30 in association with a cathode-ray tube 1, and a film-distortion compensating D.C. voltage is produced by a phase comparator 24, 28 fed by generators 19, 20 on the shafts of a freely-rotating sprocket 10 and a driven sprocket 11. The compensating square-wave is generated by a multivibrator 42, 47 controlled by frame-synchronizing pulses from a source 55, each pulse changing the state of the multivibrator, and the square waves generated are modulated through diodes 57, 62 by the D.C. potential from the phasecomparator 24, 28 and applied to the framescanning generator 7. A third generator 39 on the shaft of shutter 31 produces a pulse for each pair of shutter positions and this pulse is applied through a valve 41 to the anode of valve 42. If valve 42 is at this time conducting, as it should be, the pulse has no effect, but if it is non-conducting the pulse renders it conducting and an additional changeover of the multivibrator occurs to produce the correct phase relationship between the multivibrator and the shutter. Specifications 476,032 and 639,785 also are referred to.
