Patent GB-344404-A (GB)
Title: Improvements in or relating to processes for preventing the solution of metals in acids
IPC: C23G1/06
Filed: 1929-10-26
Abstract: The action of acid on metal is inhibited by the addition of an insoluble controlling agent which is introduced into the acid bath in a state of fine subdivision.  A condensation product of ammonia or an amine with an aldehyde, e.g. anhydroformaldehyde-aniline, or a derivative of thiocarbonic acid, e.g. thiourea or ortho-, meta-, or para-ditolylthiourea, constitutes a suitable inhibitor which may be mixed with a buoying agent such as evaporated cellulose pulp waste liquor, starch, flour or clay.  The inhibitor, with or without the buoying agent, may be ground to a finely divided state before it is added to the bath or it may be dissolved in a solvent miscible with the acid of the bath, e.g. in concentrated sulphuric acid, acetone, alcohol or ether, in which case it is precipitated in a state of fine subdivision on addition of the solution to the bath.  Alternatively briquettes of the finely divided inhibitor and a filling agent such as sodium chloride, Glauber's salt or sugar with or without a buoying agent may be added to the acid bath.  Reference has been directed by the Comptroller to Specifications 259,200 and 287,911, [both in Class 1 (ii), Inorganic compounds, other than &c.]ALSO:The action of acid on metal, particularly in pickling baths, is inhibited by the addition of an insoluble controlling agent which is introduced into the bath in a state of fine subdivision.

Title: Improvements in carrier wave signalling systems
IPC: H03C1/52
Filed: 1925-12-29
Abstract: 268,054. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Dec. 29, 1925. Modulating systems and apparatus; combined transmitting and receiving arrangements ; homodyne receiving systems; wave detectors; multiplex signalling.-In a carrier-wave signalling system, modulation is effected -by passing the carrier current through the coils 2 and the modulating current through a coil 3 placed in the field of the coils 2. The coil 3 is secured to a shaft 5, which is thus caused to vibrate mechanically at the side-band frequencies. The shaft 5 and coil 3 are designed so that their natural frequency of torsional vibration is near the carrier frequency, and the shaft is bent into one or more loops MF1 which have the effect of transmitting the upper side-band and suppressing the lower. The theory and design formulse for these mechanical wave filters are given in the Specification. The other end of the shaft carries a coil placed in a fixed magnetic field preferably as described in Specification 243,787. the unit ME1 serving to convert the mechanical vibrations into electric currents which are transmitted through a band filter BF1 to the line ML. An ordinary telephone line may be connected to the line ML through a low-pass filter. Several systems using different carrier frequencies may be associated jointly with the lime ML. Modulated carrier currents coming in from the line ML are selected by one of the band filters BF1, and are converted by the element ME1 into mechanical vibrations of the shaft 5 and coil 3. The vibrations of the coil 3 in the carrier field created by the coils 2 effects de-modulation and transmits the resulting low-frequency current through the low-pass filter SF1 to line. A tuned circuit 1 associated with the filter SF1 prevents the carrier wave from the source C1 from reaching the telephone line.

Abstract: 1,057,477. Controlling television picture signals. HAZELTINE CORPORATION. Aug 18, 1964 [Oct. 24, 1963], No. 33692/64. Heading H3Q. In a television receiver keyed A.G.C. system with additional means for stabilizing the black level and limiting beam current in scenes of high average brightness as in Specifications 1,057,474 and 1,057,475, the video signal is applied to the cathode-ray tube and the A.G.C. circuit via networks having different A.C. and D.C. gains, and the A.G.C. cirucit is also supplied (at a second input) with a fraction of the D.C. component of the video signal, and (at the first input) with a fraction of the D.C. component of the voltage at the cathode of the cathode-ray tube. In Fig. 1 the output from the video amplifier 13 is passed to the cathode of the picture tube 15 via an RC network 23 as in Specification 1,057,475, but the sync-tip gated A.G.C. tube 28 of that Specification is fed by a further RC network 30. In addition, the beam current flowing through resistor 24 develops a voltage representing the average value of the video signal and this is applied to the cathode ef the A.G.C. tube via resistor 35. The A.C./ D.C. transmission ratios of the two networks 23, 30 are so chosen, in conjunction with any unequal transmission of A.C. and D.C. through the video amplifier, that the gain of the receiver is controlled in accordance with the average value of the video signal and at the same time the black level is preserved. The circuit can also be used with back-porch gated A.G.C. (Fig. 2, not shown). Contrast control can be applied by. injecting a variable voltage at point 27 in Fig. 1 (Fig. 3, not shown).

Abstract: 477,188. Roller mills. WILLIAMS, J. L. Dec. 11, 1936, Nos. 34074/36, 2878/37, and 12115/37. [Class 59] A scraper comprises one or more thin strips of flexible metal loosely located in a longitudinal slot formed in a member pivotally disposed on a longitudinal axis parallel to the axis of the associated roller whereby the scraper is freely movable and/or is capable of rocking in relation to the member to permit the scraper aligning itself parallel to the roller. As shown thin flexible blades 1, 1a mounted in slots in tubes 2, 2a contact with rollers 10, 10a by the rotation of the tubes by rods 5, 5a adjustable by nuts 6, 6a. The nuts 6, 6a engage in the bifurcated ends of lever arms 9, 9a pivoted at 8 and another lever 9b integral with these arms is connected by a rod 11 to a clip 17 on a shaft 18 by which the rollers are separated so that the scrapers are removed from the rolls when the latter are separated. Lost motion at either end of the rod 11 may be provided so that the rolls are separated before the scrapers leave the rolls. In a modification the tubes 2, 2a are provided with rearwardly extended arms connected by a spring by means of which pressure is exerted by the scrapers on the rolls. Instead of a spring a non-extensible connection pressed laterally by a spring may be used. The scrapers may also be tensioned by eccentrically mounted presser bar or bars and the scraper may consist of a plurality of parallel scrapers carried in overlapping short tubes and adapted to be rotated independently. The scrapers 1, 1a are loosely mounted in the tubes 2, 2a and may be secured by bolts passing through the tubes and through enlarged holes in the scrapers, and the inner longitudinal edge in the tube may be curved so as to be rockable in the slot to adjust for non-parallelism between the scraper and roller.
