Title: Electrical signalling system with a constant number of signal elements and two alternating current frequencies
IPC: H04L25/49
Filed: 1947-12-17
Abstract: 652,262. Electric selective signalling. STANDARD TELEPHONES & CABLES, Ltd. Dec. 17, 1947, No. 33289. Convention date, June 1, 1943. [Class 40 (i)] In a code signalling system each signal consists of a constant number of alternating current code elements at one or the other of two frequencies f1, f2. At the receiver each signal element steps a counter and recording means and the positions of the signal elements of one only of the frequencies (marks) are recorded in their relative sequential positions. Fig. 2 shows the receiver for a system using a four element code catering for ten different digits. The relays F1r, F2r respond respectively to impulses at frequencies f1 (space) and f2 (mark). On receipt of the first signal element the relay B1 energizes in series with the normally energized relay A1. Relay A2 energizes as the first impulse ends, and when the second impulse starts B2 energizes in series with A2 and A1, B1 relapse. Similarly, at the end of the second impulse A3 energizes, and at the start of the third impulse, B3 energizes in series with A3, and A2, B2 relapse, and so on for the fourth impulse at the end of which relays A4, B4 are held in series until receipt of the next signal. The counting relay chain A1, B1, &c. is sequentially operated in this manner by the received code elements, irrespective of the frequency thereof to step a recording unit correspondingly. When a code element is of frequency f2 earth is extended by the relay F2r to actuate the appropriate recording magnet R1 ... R4, according to the operative element of the counting relay chain, to record a " mark." Modification. A different number of signal elements may be used for the code and, in a modification, the relay F1r may be aperiodic or otherwise adapted to respond to either of the signal frequencies and alone operates the counting chain, relay F2r functioning exclusively to operate the respective recording magnets.

Title: The recovery of tar acids from tar oils
Inventor: HOLDSWORTH ERNEST CLIFFORD
IPC: C10C1/00
Filed: 1954-11-24
Abstract: Tar acids such as phenols and cresols are sprung from a solution of the corresponding sodium salt or salts by mixing the latter with an anolyte from the electrolysis of a substantially saturated solution of sodium sulphate, the catholyte or caustic soda separated therefrom or (in the case of a mercury cathode cell) obtained from sodium amalgam formed by the electrolysis, being used to wash the tar acids from a tar oil.  The electrolytic cells used are a diaphragm cell or a mercury cathode cell, the anolyte from both comprising a solution of sodium sulphate and sodium hydrogen sulphate.  The catholyte from the diaphragm cell comprises a solution of caustic soda and sodium sulphate, a similar solution may be obtained from the mercury cathode cell by reacting the sodium amalgam with saturated sodium sulphate solution.  Alternatively the amalgam may be reacted with water to give caustic soda solution.  In an embodiment, sodium sulphate solution is electrolysed in a diaphragm cell, the catholyte is used to wash tar oil, the extract is washed with naphtha and is mixed with the anolyte.  The phenol layer is removed and the sodium sulphate solution regenerated is dephenolised and/or concentrated by washing with toluene or naphtha or boiling or steaming and returned to the cell.  An example is given.

Abstract: A pharmaceutical preparation valuble in the treatment of gastro-intestinal nematode infectations comprising an N-benzyl-N,N-dimethyl-N-2-phenoxyethyl ammonium salt, e.g. chloride or bromide together with a neutral nonaqueous excipient. The quaternary ammonium salt alone, or in admixture with an inert powder such as lactose is used in hard gelatin capsules.  For filling into soft gelatin capsules the active ingredient is dispersed in a mineral or vegetable oil.  A tablet is prepared by mixing N - benzyl - N,N - dimethyl - N - 2 - phenoxyethyl ammonium bromide with 1% magnesium stearate and tabletting.  In another case, the active ingredient as chloride is mixed with lactose and starch, moistened with 10% gelatin in 50% aqueous ethanol and granulated.  The granules are mixed with magnesium stearate and tabletted.  The tablets are coated with gum acacia, gelatin and sugar and then with shellac in alcoholic solution.  In another example, tablets containing the active ingredient as chloride are coated with cellulose acetate-phthalate dissolved in a mixture of equal parts of 95% ethanol and ethyl acetate containing 12% ethyl lactate.

In operation, an input source 6 applies a positive coded input signal at 5 and a negative coded input signal at 4. When transistor 22 is enabled, it is rendered conductive by the negative portions of the input signal at 5 applied via a level shifting network 25-27 and rendered non-conductive by the positive portions applied via a diode 28 during which non- conductive periods, a transformer 23 rings to produce positive pulses at the non-dot end of the secondary. The transistor 15 when enabled and switched off acts in a similar fashion to produce positive pulses at 12 in response to a signal present at 4.

Abstract: 871,396. Glass fibres. PITTSBURGH PLATE GLASS CO. Nov. 11, 1957 [Nov. 9, 1956], No. 35063/57. Class 56. Fibres are produced by introducing a heat softenable material e.g. glass, into a high temperature, high velocity gaseous blast, attenuating the material into fibres in the blast which for a portion of its travel is completely enclosed so as to exclude the surrounding atmosphere, and increasing abruptly the crosssectional area of the blast at a point where the fibres are in an attenuable state, the surrounding atmosphere being excluded, so as to increase the turbulence of the blast abruptly. The blast may be provided by flowing a fuel-oxidant mixture from a burner port and combusting the mixture. The blast may be stabilized with at least one adjacent pilot flame which may have a strength at least that represented by _the equation q = #. h. Uc. where q is the pilot flame strength, h is the excess enthulpy of the combustion wave, # is the pilot-flame efficiency and Uc is the critical velocity of the blast according to the equation Uc = ¢ À # À 2u./2v. where U is the local flow velocity, y is the distance normal to the direction of flow measured from the direction of flow measured from the wall of the burner port, and # is the thickness of the combustion wave in the blast. Heat may be added to the blast to maintain the fibres in an attenuable state. As shown in Figs. 1 and 2, a glass body 28 is introduced into blast 38, which are stabilized by pilot flames 41, enclosed in duct 50 to produce fibres 37. The duct is composed of two sections A and B, the cross sectional area of B being considerably greater than that of A, and the change of section A to section B being abrupt as shown in Figs. 3, 4 and 5. Heating means 68 may be located in insulation 65 adjacent the portion of the duct of larger cross-section, or the temperature of that portion of the duct may be controlled by the entry of hot or cold gaseous blasts through walls 62 at an angle to the blast 38. The glass may be introduced in any form and at any angle, thus, in Fig. 6, molten glass 85 is extruded into blast 89 formed by blasts 90 and 91. Specification 648,909 is referred to.
