Title: Improvements in and relating to balancing machines with electrical indicating devices
Filed: 1951-09-12
Abstract: 694,834. Electric indicating systems. PISCHEL, W. Sept. 12, 1951 [Sept. 14, 1950], No. 21447/51. Class 40 (i) [Also in Group XL(b)] In a balancing machine wherein the phase of an alternating current generated in accordance with the unbalance of the revolving test body is compared in a meter with that of a reference current of the same frequency, the phase of one of these currents is continuously changed slowly by a rotating phase advancer, the drive to which is stopped automatically on zero reading of the meter, i.e. when the phase displacement is 90 degrees or 270 degrees, and at the same time a further switching is effected to produce a further phase displacement of 90 degrees. As shown, pick-offs 5, 5<SP>1</SP>, arranged e.g. as disclosed in Specification 688,234, develop alternating voltages corresponding in magnitude and phase to the unbalance of the motor driven rotor 1, which are amplified at 6 and fed to a known phase comparator 16, Fig. 2 (not shown). The reference voltage is derived from a selsyn system 7, 9, of which the single phase rotor of transmitter 7 is energized with direct current and driven by the rotor 1, and the rotor of receiver 9 is slowly driven by an auxiliary motor 13 through reduction gearing and an electromagnetic clutch 14. The receiver rotor output which is of substantially the same frequency as the pick-off potentials, is thus continuously varied in phase, -and is compared with the unbalance potential in the phase comparator 16, which delivers zero output to the D.C. centre zero meter 19 for phase displacements of 90 degrees or 270 degrees. When one of these phase relationships is reached the meter photo-electricallv or otherwise energizesa relay 25 to release a switch member 27 which is moved to the right by a biasing spring 28, closes contacts 34, 35 to disengage the clutch 14 and at contact 31, switches a capacitor 33 into the reference voltage circuit in lieu of the resistor 32 to alter the phase displacement to zero or 180 degrees to give a maximum meter reading which is a measure of the unbalance potential, the "phase" of which is read off a scale 11 on the shaft of the selsyn receiver rotor.

Abstract: 682,730. Containers for transporting and dumping apparatus. DEMPSTER BROS., Inc. Aug. 31, 1950. [Nov. 3, 1949] No. 21502/50. Classes 78 (iii) and 78 (iv). In a container, Figs. 4 and 6, including a bottom 13, side walls 10, rear wall 11, and an upwardly and outwardly extending front wall 12, a pivot 18 is secured to the bottom 13 spaced from and parallel to the rear wall and a bail 16 engaging the pivot extends along the bottom and the rear wall, and a cover for the container includes a door which is opened automatically when the container is rotated about pivot 18 by a rope 29 secured to the door and to the bail 16. In one form, Fig. 3, the cover consists of a curved top wall 23 extending to a pivot 25, a pair of side walls 24, and a door 26 pivoted to it at 25 and having flanges 27 which slide within the walls 24 when the door is closed. The rope 29 is connected at 30 to a comb 28 upstanding from the door 26 and is passed over pulleys 32 to the point 33 on the bail. The front wall 12 is provided with spaced lugs 37 on which are pivoted legs 38 to which is secured a common shoe 40. In operation, a pair of chains 21 are secured between anchorages 20 on the side walls 10 and spaced points 54 on the end of a boom structure 45 which is raised and lowered about pivot 46 on a vehicle by a fluid pressure ram 48. The container is then raised up a skid plate 50 in its upright position to the chain line position, Fig. 3. For transporting the container skid plate 50 is movable forwards on the vehicle by a second ram so that the container can be lowered on to a platform 53. For damping however, skid plate 50 remains in the position shown and in the chain line position shown a pivoted hook 51 automatically engages the bail 16. The boom structure is then lowered causing the container to rotate about the pivot 18 into dumping position shown in full lines, the chains 21 each catching on a deflecting pin 22 on walls 10 to assist subsequent raising of the container. This rotation causes rope 29 to open door 26 as shown. In a second form, Fig. 4, the pivoted door is replaced by a sliding door 57 provided with rollers 56, 58 engaging guide rails 55 on the side walls 24. The top wall 23 in this case extends to the point 54<SP>1</SP> and door 57 slides outside this, rope 29 being connected to it at 59. In a third form, Fig. 6, side walls 24 extend only to the edge 60 and the door consists of both a top wall 61 and side walls 62 which are pivoted at 63 on the inside of walls 24. Top wall 23 extends to a reinforcing plate 67 having a guide hole for rope 29, the latter being connected to the door at 64. The door in this case opens within the cover. Springs 65 connected between the door and side walls 10 assist manual opening of the door for charging the skip. In the first two forms, however, a separate door 34 is provided in side wall 24 for charging purposes. Specification 547,680 is referred to.

Filed: 1951-09-14
Abstract: 700,336. Washing gases. FARBENFABRIKEN BAYER. Sept. 14, 1951 [Oct. 6, 1950], No. 21669/51. Class 55 (2) In a gas washing process, the gas is passed up or down through a funnel whilst an axial jet of liquid is projected up through the gas to a reversing device above the funnel, the liquid being collected in the device and returned to the inner surface of the funnel or of a jacket surrounding the funnel to form a liquid film thereon. In the form shown in Fig. 1 the gas enters a funnel 1, e.g. a chimney, at 12 and discharges from its open upper end. A nozzle 2 directs a jet of water up through the funnel so that it impinges on a device 5 which reverses its direction, the water collecting in a trough 8 from which it is led by pipes 6 to the inner surface of the funnel. The pipes 6 are set tangentially to the funnel so that the water forms a rotating and descending film thereon. The water collects in a sump 9 and is recycled to the jet 2 by a pump 3. When the gas is required for other purposes, the apparatus is modified as shown in Fig. 2. A jacket 1a surrounds the funnel, the wash liquid being returned to the inner surface of the jacket. The gas can flow through the funnel and jacket in series in either direction.

Abstract: 1510700 Cathode-ray-tube circuits GENERAL ELECTRIC CO 21 May 1975 [21 June 1974] 21739/75 Heading H4T A convergence circuit for a multi-gun (colour) cathode-ray tube comprises means for producing a correction current function involving the square and linear terms of both the vertical Y and horizontal X deflection amplitudes and a term proportional to the product X, Y and a function of a further term proportional to Y<SP>3</SP> where Y in this case is the positive portion of the vertical deflection signal. As shown in Fig. 1, a horizontal sawtooth wave derived from differential amplifier 16 and a vertical sawtooth wave from differential amplifier 36 are supplied to the circuit including multipliers 24, 26 and 44 and the differential amplifiers 20, 30, 40 and 48 operating as inverters to produce the function terms indicated. The latter are then supplied via adjustable potential dividers 52, 54, 56, 58 and 60 and respective summing resistors 64, 66, 68, 70 and 72 to the subtractive input of driver amplifier 62 the output of which is connected to the convergence coil 74 for one of the guns of the tube. A sense resistor 76 and summing resistor 78 provide negative feed-back. An arrangement according to Fig. 2 is required for each gun of the tube. In accordance with the invention a half-wave rectifier 80 (Fig. 1) rectifies the positive portion of the vertical deflection wave the output of the rectifier being multiplied in multiplier 82 with the Y<SP>2</SP> output of multiplier 44 to provide the function Y<SP>3</SP>. This is supplied via the potential divider 84 and summing resistor 86 to the subtractive input of drive amplifier 62 in respective arrangements of Fig. 2 concerned with the red and green guns only since the blue gun, the axis of which lies in the plane of vertical deflection, does not require this additional term the effect of which is to further reduce convergence errors in the central part of the raster. The invention may be employed with other than a rectangular raster, e.g. a PPI indicator sweep. In the latter case different classes of target returns may be presented in different colours.

Abstract: Textile assistants having wetting, washing, dispersing, and emulsifying properties are obtained by the sulphonation of hydrogenation products boiling above 200 DEG  C. obtained from mineral coals or coal tars or their dehydrogenation products.  High molecular constituents such as naphthalene, anthracene, pyrene, chrysene and fluorene may be separated before the sulphonation process, and in the case of pitch fractions boiling above 400 DEG  C. being used they may be first extracted with alcohol, carbonbisulphide or other solvent.  Acid anhydrides or halides, e.g. acetic anhydride or phosphorus pentoxide may be present during the sulphonation.  The products, which may be after treated with bleaching earths, sodium hypochlorite or animal carbon may be used for the preparation of emulsions for use in the textile, paper and leather industries.  Dark coloured products may be used for emulsifying bitumens.  In an example, a coal hydrogenation product which has been dehydrogenated according to the process described in Specification 435,254 is fractioned and the pitch fraction extracted in the cold with carbon bisulphide.  Both the residue and the extracted product, the latter after removal of the solvent and pyrene and chrysene, are sulphonated with sulphuric acid.  Specifications 247,582 and 272,829, [both in Class 32], also are referred to.ALSO:Sulphonic acids stated to have dispersing and emulsifying properties are obtained by sulphonating hydrogenation products boiling above 200 DEG  C. obtained from mineral coals or coal tars or dehydrogenation products thereof.
