Title: Method and apparatus for the controlled withdrawal of granular solids from a liquid granular solids contacting zone
IPC: B01J47/10
Filed: 1955-06-20
Abstract: A process in which a hydrocarbon oil (e.g. mineral oil) is treated (e.g. decolorized or converted) by contacting it with granular solids (e.g. fuller's earth) within a confined contacting zone is characterized by passing a stream of liquid-solids slurry downwardly from the contacting zone through a confined drain passage, discharging the stream on to a perforated surface so that wet solids are retained on the surface around the lower end of the passage to form an accumulation having a defined liquid content which is a function of the liquid viscosity, the accumulation substantially impeding the the downward flow of the stream, and mechanically removing wet solids from the <PICT:0783569/III/1> <PICT:0783569/III/2> accumulation at a controlled rate to effect the desired rate of solids flow.  The treatment plant is of the general type shown in Specification 711,487 and includes the apparatus described below for controlled withdrawal of solids interposed between the oil-treater and the solids-washer, and again between the solids-washer and the solids-drier.  In Fig. 3 liquid-solids mixture issuing from the collector of the treater or from the foot of the washer (neither shown) emerges at 63 on to a rotating screen 57 where a pile 68 of solids formed by drainage through the screen checks downward flow through the pipe 63.  The solids are carried round under a roller 69, Fig. 4, and are forced by a scraper 70 into a collecting box 23 for passage to the next stage of the process.  The rate of solids withdrawal through pipe 63 is controlled by adjusting its distance from the screen 57 or by regulating the speed of rotation of the screen or both.  A backwash pipe 65 is provided.  In Fig. 7 the rotating screen is replaced by a travelling band screen 75 whose rate of travel may be varied.  In both cases vacuum may be applied to the underside of the perforated surface.  The screen may comprise 100-mesh stainless steel woven wire screening supported on a grating with 1-inch square openings and provided with drip points to facilitate draining.  More than one pipe 63 may be used.  In the drier (not shown), adsorbent is maintained as a fluidized bed by a condensable stripping gas and heat is supplied by indirect heat exchange.  Vaporized stripping gas and solvent are passed to a quencher and there condensed by cold water while dried adsorbent is passed through a kiln, where impurities are burned off, back to the oiltreater.

Title: A method of bonding intersecting threads of fabrics made of polymeric threads
IPC: D06M15/39
Filed: 1962-05-10
Abstract: The slippage of the threads of a fabric made of synthetic polymeric threads is restrained by applying to each individual thread of the fabric at selected intersections thereof with other threads of the fabric, discrete quantities of a bonding agent to produce spaced welds so that the number of unbonded intersections of the individual thread with other threads of the fabric between any one weld of the individual thread with another thread and the next following weld of the same individual thread with a different thread of the fabric is normally at least one and does not exceed ten so that normally intersections of the threads immediately adjacent to any one weld have no bonding agent applied thereto, the bonding agent being applied to the selected intersections of the threads by a printing process, e.g. screen printing, and the bonding agent being so selected that it produces with the polymeric thread material a polymer having a greater chain length when the materials are the same or a copolymer when the materials are different and the bonding agent being applied to the thread material in a solvent which is also a solvent for the material of at least one thread at each of the intersections.  The threads may be made from polyamides, polyacrylonitrile; polyethylene terephthalate or polyvinyl chloride and the bonding agent may be a polyamide, polyethylene terephthalate or polyacrylonitrile. Suitable solvents are phenol hydrate, m-cresol, cresylic acid, tetrachloroethane and dimethyl formamide and the application may be made at room temperature or above.  After treatment with the bonding agent the fabric may be dried slowly, drying being effected by bombardment of the treated fabrics with electrons, protons and/or neutrons by irradiation with X-rays, ultra-violet rays or rays emitted from radioactive isotopes or by exposure to sunlight.  Stockings may be treated.

Title: Convergence deflecting device for single-gun, plural-beam color picture tube
IPC: H01J29/51
Filed: 1969-04-09
Abstract: 1,223,969. Colour television tubes. SONY CORP. 9 April, 1969 [14 April, 1968], No. 18063/69. Heading HID. In a colour television receiver tube of the type wherein three co-planar beams diverge from a common focusing lens and are converged on to a shadow mask or the like by two pairs of deflection plates, the latter are curved in the direction normal to the plane of the beams to correct for raster errors. In Fig. 7 the three beams B R , B G , B B  lie in a horizontal plane and the deflection plates PP<SP>1</SP>, QQI are divergently curved in a vertical plane. This corrects for raster errors (Fig. 3, not shown) caused by the outside beam following a longer path in the field of the magnetic deflecting yoke than the inside beam or the centre beam at large deflections; at zero vertical deflection (i.e. in the central positions of the beams as shown) the error in horizontal deflection may be corrected by a non-uniform scanning field but the error remains at large vertical deflections unless corrected as described. In modifications the inner plates P (Fig. 4, not shown) or the outer plates Q (Fig. 5, not shown) are planar. For correcting the opposite type of raster error the plates are curved in the opposite sense (Figs. 6 and 8, not shown). When there are two sets of convergence deflection plates the set nearest the magnetic deflection yoke should be shaped as described.

Filed: 1971-05-28
Abstract: 1386797 Automatic control of speed DUNLOP Ltd 22 May 1972 [28 May 1971] 18079/71 Heading G3R A system for controlling the speed of a D.C. motor employs a switching circuit which provides a series of current pulses at a constant frequency whose duration is varied in accordance with an input signal derived from an integrated error signal and a stabilizing differentiated feedback signal. The error signal is derived from the difference between the actual speed provided by a tachometer 1 and the desired speed produced as a voltage in command input 6. The switching circuit 5 comprises a ramp generator 14 providing a saw-tooth waveform which is then divided into positive and negative parts in phase splitter 16 separated by an amount which represents the dead band in the system. The input signal from summating device 8 is applied to the modulators 17,18 and depending on its level and polarity may intersect the sawtooth waveform in one of the modulators to provide output pulses which are used in one of the power drivers 19,20 to gate current to the motor 1 through the respective SCR bridge 3 or 4 depending on the direction of motor rotation required. The integrator 9 is used to ensure that the signal applied to 8 provides a rapid response to any change in the system. The feedback loop 12 provides an acceleration signal and this signal is poled to oppose any speed change.  In a modification a split-field or armature winding is used, which may consist of oppositely wound coils, and the forward and reverse power is applied to different parts of the winding or differend coils appropriately.

In a spectral analysis instrument such as a spectrophotometer the angular position of the dispersing means and/or the widths of the entry and exit slits is or are measured with the aid of one or more optical systems each having a mirror which projects a line image on to a fixed scale and which is moved on adjustment of the dispersing means or of the slit widths as the case may be, so that the line image takes up a new position on the scale corresponding to the adjusted angular position or slit width. As shown in Fig. 4, the spectrometer comprises an entry slit En, the radiation from which is collimated at a concave mirror C2 and falls on a rotatable refraction grating R, the dispersed radiation being focused by a concave mirror C3 on to an exit slit St. Attached to the rotary axis of the diffraction grating R are three plane mirrors M1-M3 which are differently inclined to the axis and which project on to a screen carrying fixed scales, line images of a reticule disposed in the light path between a lamp and the mirrors. The two slits are disposed in a common plane and the two jaws of each slit are connected to plane mirrors so that on relative linear movement of the jaws the plane mirrors are relatively rotated. A line image is projected on to one mirror and thence on to the other mirror from which it proceeds to a fixed scale which may be on the same screen as that which carries the scales corresponding to the diffraction grating. The intensity of the radiation passing through the exit slit may be measured by a photo-cell and galvanometer the reading of which may also be projected on to a scale carried by the same screen.

Title: Crossing conductor matrices

Filed: 1969-04-09
Abstract: 1,263,568. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. 9 April, 1969 [10 April, 1968], No. 18275/69. Heading H4K. A diode or other matrix in which undesirable current leaks due to breakdown of a cross-point element may occur includes means to indicate this fact when it detects that the potential of one of the orthogonal conductors has deviated from its normal range of operation. In the matrix shown each cross-point element is a relay and series diode and is operated by opening a row gate such as Tx1 connecting to positive potential and a column gate such as Ty1 connecting to negative potential. The gates may be transistors. The free end of each row conductor is connected via a resistor such as Rxl to earth and each column conductor is similarly connected e.g. by Ryl to positive potential. These resistively applied potentials are used in conjunction with corresponding AND gates such as Pyl to detect leak currents in the diodes connected to the corresponding conductor. Each AND gate such as Pyl receives the potential of its conductor such as yl, a reference potential E0 which during normal operation is about the same value and periodic testing pulses applied at input T. The reference potential and the potential of y1 are resistively combined and hold a capacitor within the gate at a level at which it normally absorbs the pulses T which are applied so as to pass through it. If the potential at y1 drops due to a current leak in the form of a backward current through a cross-point diode the combined potential drops allowing part of each pulse T to pass through the capacitor and cause a diode in the gate to conduct producing an output indication via an amplifier. By synchronizing the testing pulses with the operation of the cross-points and comparing the leak indications with the addresses of the cross-points operated faulty cross-points can be identified.
