Title: Apparatus for the treatment of textiles by means of liquids
IPC: D06B5/16
Filed: 1960-06-14
Abstract: <PICT:0876506/IV(c)/1> <PICT:0876506/IV(c)/2> <PICT:0876506/IV(c)/3> An apparatus for treating textiles with liquids, e.g. for dyeing textile fibres rolled on bobbins, comprises a liquid-containing closed vessel carrying a series of perforated tubes on which the bobbins are threaded, the tubes being connected to a receiver communicating with the interior of the vessel, while a reversible pump circulates the liquid in a closed cycle through the receiver and vessel, so that the bobbins are treated with the liquid, the inlet of the receiver being inside the vessel and constituted by part of the stator of the pump, in such a manner that the liquid in the receiver is separated from that in the vessel only by a rotor of the pump. Referring to the Figures, liquid passes from the receiver 3 (Fig. 1) and perforated tubes 4 (carrying bobbins 5) into vessel 1 by means of pump 8, whose stator 9 carries cap 10 forming the inlet for receiver 3; vents 11 on the base of stator 9, inside vessel 1, communicate with the interior of receiver 3 via rotor 12.  The hollow rotors 13 communicate via channels 15, 18 and 19 with reservoir 20, which carries the treating liquid and which may be opened or closed.  A modification (Fig. 4) carries a ring 21, around the vents 11, which can be partially rotated to make or break communication between vents 11 and reservoir 20.

Chain gearing, variable-speed, for cycles, comprises two chain-wheels on the crank bracket, loose and adapted to be connected alternatively to the crank bosses B, B<1> by spring plungers D. Chains connect these wheels to free-wheels on the hub. To bring one wheel into action, the plungers of the other are retracted, for which purpose that other wheel is stopped. In the arrangement shown in Figs. 1 and 2, a transversely pivoted lever is used to withdraw the plunger D of either wheel. In a modification, levers opening like scissors are used. In the arrangement of Fig. 8, a non-rotary cage is slid axially, acting through bell-crank levers.

Title: Improvements in or relating to automatic frequency-control circuits for electric oscillators
IPC: B06B1/16
Filed: 1949-08-16
Abstract: 675,105. Valve generating circuits. PHILIPS ELECTRICAL, Ltd. Aug. 16, 1949 [Aug. 19, 1948], No. 21297/49. Class 40 (vi). In a circuit for synchronizing a crystalcontrolled oscillator by means of an alternating synchronizing voltage the amplitude of. the synchronizing signal is controlled in accordance with the difference between the natural frequency of the oscillator and the frequency of the synchronizing signal, being greater as this frequency difference increases, Fig. 1 shows in schematic form a crystal oscillator 11 in which an A.C. synchronizing signal supplied at terminals 1, 2 is limited in stage 5 applied to the amplifier stage 8 via the variable phaseshifting network 7, 34 and is applied to the oscillator circuit across the cathode resistor 10. The relative phase of the synchronizing signal to that of the oscillator output voltage which varies with the difference between the' natural frequency of the oscillator and the synchronizing signal frequency are compared in a phase comparator circuit 22 from which a negative D.C. control voltage is produced at point 31 proportional to this frequency difference. The control voltage at point 31 is applied to control the gain of amplifier stage 8 and thus the level of synchronizing signal applied to the oscillator across resistor 10. The phase-shifting network 7, 34 is adjusted so that during synchronization the phase-shift is slightly less than 90 degrees so that the synchronizing voltage is slightly greater than is necessary for synchronization. The milliammeter 33 is calibrated so that the frequency difference between the natural frequency of the oscillator and the synchronizing voltage frequency can be read directly from it. When this frequency difference exceeds a pre-determined amount the slow-to-release relay A operates, disconnecting the synchronizing voltage from resistor 10 and sounding an alarm circuit (not shown). The output of the oscillator may be taken from across the load resistor 21 and the oscillator is stabilized by a negative feed-back circuit comprising a lamp 18. Fig. 2 shows a circuit in which the gain of an amplifier stage 38 is controlled in accordance with a negative control voltage which is derived from a rectifier 46 in the cathode circuit of the oscillator valve. This negative voltage which is partly off-set by a positive threshold voltage from battery 47, is proportional to the amplitude of the alternating current flow in the cathode circuit of the oscillator which is dependent upon the frequency difference between the natural frequency of the oscillator and the frequency of the synchronizing signal.

Abstract: 681,770. Liquid gauges. SIMMONDS AEROCESSORIES, Ltd. Aug. 13, 1951 [Sept. 5, 1950], No. 21853/50. Class 37. A liquid contents gauge, in which the capacitance of a condenser is varied in accordance with the depth of the liquid, is provided with means for indicating the departure of the dielectric constant of the liquid from that of the liquid for which the gauge has been calibrated and correspondingly adjusting the reading of the indicator. A measuring condenser 1 is arranged in the liquid container 2 so as to extend from the top to the bottom and is connected through a switch 4 to a measuring system 10 that includes an A.C. source 5 and an indicator 6. The container 2 is provided with a sump 7 in which is located a standard condenser 8 so that it is wholly immersed in the liquid. The condenser 8 is connected to the switch 4 so that either of the condensers 1, 8 may be connected to the measuring system 10. With the condenser 8 connected a reading is obtained on the indicator 6 which is dependent, at constant temperature, solely on the dielectric constant of the liquid in the container 2. The measuring condenser 1 is then reconnected and the readings of the indicator 6 may be corrected by adjustment of calibrated variable resistors 11, 12 arranged to adjust the scale length and zero setting. The switch and control device may be operated by a single knob which is pulled or pushed against the action of a spring to substitute the standard condenser 8 for the measuring condenser 1. By turning the knob while in this position the control device may be adjusted to bring the indicator pointer to a reference position corresponding to the dielectric constant of the liquid. On releasing the knob the measuring condenser is reconnected and the indicator is adjusted to the dielectric constant of the liquid being gauged. A second control device for adjusting the zero setting may be ganged with the first. Specification 560,872 is referred to.

Abstract: 1,193,590. Casting composite articles. DOW CHEMICAL CO. 8 May, 1968, No. 21855/68. Heading B3F. [Also in Divisions C1 and C7] A low density metal body, for flotation aids for water craft or low density cast or machined parts where strength is not important, comprises 0À1-25% by weight of vermicular expanded graphite having a density of 0À2-10 lbs./cu. ft. dispersed through a matrix of a metal or alloy which is substantially unreactive with the graphite at the melting point of the metal or alloy, and contains essentially closed cell voids within the graphite particles. The metal may be Mg, Al, Pb, Cu, Zn, Ni, Ag, Au, Pt, Sb, Cd, Sn or Bi. The graphite may be prepared by chemically or electrically oxidizing particulate natural graphite at about room temperature followed by heating (e.g. at 150-1200‹ C.) to expand it. The composite is then prepared by applying pressure to the metal or by drawing the molten metal into a vermicular expanded graphite mass in a mould, such as an inverted beaker of stainless steel, e.g. by applied vacuum or by the autogenous vacuum produced by reaction of the melt with oxygen and nitrogen in the graphite mass.
