Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1929-11-13
Abstract: 343,088. Automatic exchange systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, and TAYLOR, R., 30, Oulton Road, Wavertree, both in Liverpool. Nov. 13, 1929, No. 34703. [Class 40 (iv).] In a system using Strowger-type finders controlled by relays in an allotter FA, a relay C in the allotter is energized in series with the vertical magnet VM and falls back at the end of the vertical movement to bring the rotary magnet RM into action. An interrupter relay G coacts with VM and RM in turn over the same wiper 5 of the allotter. As shown, double-wiper finders may be used, the relay G in its rotary function being energized over its right winding from test wiper PI and connecting its left winding to P2 to determine whether it shall remain energized or not. As in Specification 293,294, [Class 40 (iv), Telephones &c.], a line is marked calling by removing ground from its individual test wire and bv grounding the appropriate terminal in a vertical bank VB. Sparking in the finders is prevented by a quench Q, 12 in the allotter. Vertical hunt. Relay A energizes K (DM not operating) which closes a circuit for VM through C. A short is removed from FR allowing it to energize in series with a selector line relay (not shown). Interaction proceeds between VM and G to step the finder vertically. Stepping ceases when VW reaches the calling level, marked by ground, G being held up over wiper 6 until C falls back. Rotary hunt. Interaction then proceeds between RM and G in a circuit including KR, which locks up. Each time that G pulls up over its right winding it closes a locking circuit for its left winding, but this is ineffective by reason of a short from wiper P2 as long as this wiper finds grounded terminals. If the call is in the bank of wiper P1 stepping ceases when P1 finds the ungrounded terminal, G failing to re-energize and HA (no longer shorted at P1) being energized over wipers 6, 5 in series with G (which is not operated in this circuit). If the call is in the bank of P2 stepping ceases when P2 reaches the ungrounded terminal, G being energized from PI and remaining locked over its left winding and HB (no longer shorted at P2) being energized over wipers 6, 7 from resistance 11. In either case HA or HB locks itself between P (grounded by the selector release relay) and VM, and switches through, P being connected to P1 or P2 to ground the calling terminal and to energize the subscriber's cut-off relay. Relays FR, K, KR fall back and DM is connected to wiper 1 to drive the allotter to the next idle finder.

Title: Improvements in or relating to the saponification of cellulose esters
IPC: D06M11/38
Filed: 1933-12-12
Abstract: Cellulose organic ester materials particularly filaments yarns, fabrics, and ribbons are partially or completely saponified by treatment with a non-metallic non-aromatic nitrogenous base in the presence of a heavy metal or a compound of such metal.  The metal is preferably one which forms a double or complex compound with the base, but not a compound of the metal-ammine type.  Metals which may be used are copper, nickel, silver, zinc, cobalt, chromium, and platinum.  The metal may be added to the saponifying bath in the form of a soluble salt, or as a hydroxide, or oxide. The organic ester of cellulose may be the acetate, formate, propionate, butyrate, or ethyl cellulose acetate, formate, propionate, butyrate, or ethyl cellulose acetate, oxy-ethyl cellulose acetate, or cellulose nitro-acetate, and it may have high, low or normal viscosity characteristics.  Filaments may be treated continuously with production by dry or wet processes, or continuously with a stretching process.  Stretching may be effected subsequently to saponification.  The organic base may be ammonia, piperidine, methylamine, ethylene diamine, ethyl, propyl, amyl, triethyl, trimethyl, or allyl amine, or tetramethyl ammonium hydroxide, or propylene, methyl ethylene, or s-dimethyl ethylene diamine, or 1.2.3-triamino propane, or a g -diamino-b - hydroxy propane.  Saponification may be effected at raised temperature, and the liquid may be covered with a layer of oil or wax to prevent excessive evaporation.  The metal or metal compound may be applied to the materials prior to application of the saponifying p  liquid or it may be added to the spinning solution.  Filaments and yarns may be treated in warp formation, or in hanks, bobbins, cheeses, or other packages.  The material may be treated with water, soap solution or other wetting agent to facilitate penetration of the saponifying liquid.  In an example, cellulose acetate in warp formation is treated with an aqueous solution of methylamine to which a small quantity of silver nitrate has been added.  Specifications 207,562, [Class 2 (ii)], 417,220, 429,103, and 430,349 are referred to.  The Provisional Specification refers also to compounds of cadmium and mercury and Specifications 323,790, [Class 2 (ii), 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 370,430, 371,461, 378,858, 389,823, 402,105, 411,094, and 429,447 also are referred to.

[Also in Groups XII] Synthesis gas is produced with simultaneous production of energy by incomplete combustion of hydrocarbons preferably methane in a gas engine the components of the combustion mixture being intimately mixed outside the engine to provide a mixture which contains 1.52 or fewer atoms of oxygen to one atom of carbon, the mixture being supplied to the engine by way of an intermediate container, and the engine is arranged to operate so that the maximum indicated ignition pressure at each stroke of the piston reaches or exceeds 35 kg/cm<SP>2</SP>. The functioning of the engine is improved if the ignition is advanced to at least 17 degrees before top dead centre. Using a gas mixture which contains 1.48 or fewer atoms of oxygen to one atom of carbon an advance of 22 to 30 degrees has proved most favourable. The mixture may contain gases such as nitrogen and/or gases such as carbon dioxide or water vapour. In one example crude methane containing 97 per cent. of methane, 1 per cent. of hydrogen and 2 per cent. of nitrogen is partially burnt in a gas engine with oxygen which contains 98 per cent. oxygen and 2 per cent. of nitrogen. The ratio by volume of oxygen (100 per cent.) to methane (100 per cent.) is 0.7. When the compression ratio is adjusted to 1:7.55 and the ignition advanced to 19 degrees before top dead centre the indicated ignition pressure is 28-33 kg/cm<SP>2</SP>. The engine runs irregularly. If the compression ratio is increased to 1: 8.8 (indicated ignition pressure of 37-41 kg/cm<SP>2</SP>) the engine runs with complete regularity. If the ignition is set at 13 degrees before top dead centre the indicated pressures amount to 34-37 kg/cm<SP>2</SP> and the engine runs irregularly. It is possible to operate with a mixture ratio of for example 1 part by volume of methane to 0.76 to 0.70 parts by volume of oxygen. The ignition advance or the compression ratio may be adjusted so that knocking of the engine just does not occur.
