Title: Improvements in telephone systems
IPC: H04Q1/32
Filed: 1925-11-09
Abstract: 265,678. Standard Telephones & Cables, Ltd., Baker, J. H. E., and Hardwick, J. R. Nov. 9, 1925. Semi-automatic exchange systems.-A relay group associated with the outgoing end of a manual-to-automatic trunk is modified for impulse-repeating and talking as required under the control of off-normal springs on the manual-operator's impulse-transmitter. The first closure of these springs also causes the operation of a relay which switches through the talking conductors, this arrangement preventing premature ringing due to an incorrect operation of the dialling and ringing keys. In the system shown, the insertion of the plug into the jack of an outgoing trunk energizes relay S which completes a loop across the outgoing conductors through both windings of relay I and the upper winding of relay F. When keys RE, DK are thrown, relay C operates over the tip of the plug in series with the impulsing springs of the operator's dial. As soon as the dial moves off normal, a circuit is completed over the ring of the plug for relay A which closes a direct loop C5. A7, S5 across the outgoing conductors, the impulses from the dial being repeated by relay C at contacts C5. Relay A also operates relay B which switches through the talking conductors and locks up. At the end of each digit, relay A relapses and restores talking conditions. When the called party replies, relay F operates and completes a loop through relay C to give supervision to the manual operator.

Abstract: 685,535. Actuation of switches. BRITISH FEDERAL WELDER & MACHINE CO., Ltd., and TRIBE, T. F. Jan. 3, 1951 [Nov. 3, 1949], No. 28224/49. Class 38 (v) [Also in Group XXII] A pressure operated switch for portable welding guns comprises a switch body in the head of the gun and carrying a contact arm moved by a projection on a diaphragm plate constituting the end wall of the gun cylinder to close or open a pair of contacts in the circuit of the welding transformer at a predetermined air pressure in said cylinder. The head 11 of an air operated welding gun 12 has a bore 15 coaxial with a cylinder 14 the bore being closed on the cylinder side by a sheet metal diaphragm 16 e.g. of stainless steel. A switch body 20 is screwed from the outside into the bore 15 and carries a pair of fixed contacts 21, 22 and a spring contact arm 23 having a contact 24 to engage the fixed contacts. A projection 25 on the diaphragm 16 bears against the contact arm 23 and electrical connection to the contacts is made through the body 20 by screws 26, 27 to the fixed contacts, and by 28 to the spring contact. In operation, air pressure builds up in the cylinder 14 to bring the electrodes (not shown) together on the work and when the pressure reaches a predetermined value the diaphragm 16 deflects to close or open the switch. A micrometer adjustment of the switch may be attained by rotating the switch body.

Abstract: 1,153,484. Methane liquefaction process. TEIKOKU SANSO K.K. and L'AIR LIQUIDE SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE. 24 June, 1966 [25 June, 1965], No. 28534/66. Heading F4P. Liquefaction of a volatile gas comprising mostly methane is effected by passing compressed feed gas from a line 1, 4 through indirect heat exchangers 5, 7 cooled by evaporating propane in a closed cycle, further cooling in exchangers 12, 16 cooled by a gaseous mixture of methane and ethane also in a closed cycle, condensing the feed in an exchanger 18 cooled by an evaporating mixture of the cycling methane and ethane and expanding at a valve 20 into a separator 21 and storage container 24; the methaneethane mixture being itself liquefied by indirect heat exchange at 5,7 selectively with evaporating propane expanded through a valve 55 to about atmospheric pressure. Product liquid methane is withdrawn through a line 26, whilst the cold content of vapour withdrawn from separator 21 and container 24 is recovered in an exchanger 11 in parallel to exchanger 12 and a portion thereof is compressed at 2 and added to the feed in line 4. Propane compressed at 58, 41 is liquefied in a water-cooled exchanger 43 and expanded at 46 into a separator 47. A first portion of the liquid propane is passed through a line 51 and exchanger 5 and the resulting propane vapour is returned through lines 49, 50 to compressor 41. The remainder of the liquid propane is undercooled at 53, expanded at a valve 55 to atmospheric pressure into exchanger 7 where it liquefies the methane-ethane mixture, and returned through a line 56, exchanger 53 and a line 57 to the compressor 58. The methane-ethane mixture compressed at 80, 60 and having been cooled at 5, liquefied at 7, sub-cooled at 64 by a portion expanded at a valve 66, further sub-cooled at 69 by a portion expanded at a valve 71 is finally expanded at a valve 73 into exchanger 18 where it liquefies the feed, and the resulting cold methane-ethane vapour is returned through exchangers 16, 12 and a line 79 to compressor 80.

Title: Improvements in and apparatus for the continuous manufacture and production of polymerisation products of acetylene
IPC: C07C2/38
Filed: 1934-10-09
Abstract: <PICT:0445358/IV/1> Acetylene polymerization products, particularly monovinylacetylene, are made by a continuous process in which acetylene or a gas containing acetylene is led into an acidic cuprous salt solution at such a low temperature, e.g. 30--40 DEG  C., and at such a velocity that the gas leaving the solution is practically free from acetylene polymerization products; when dilute acetylene is treated, such as acetylene obtained by the thermal decomposition of hydrocarbons, the gas leaving the solution must also be practically free from acetylene itself.  The cuprous salt solution is continuously withdrawn, freed from absorbed polymerization products by application of heat or reduced pressure or by blowing with gases or vapours such as steam, and used again.  The solution may contain a salt of ammonium or of a tertiary amine or, as described in Specification 438,548, a salt of an alkali or alkaline earth metal or of a metal of the third periodic group (including the rare earth metals).  As shown, a gas containing acetylene, obtained by decomposition of methane in an electric arc, is passed from a holder 1 by a pump 2 to a column 3 through which an acidic cuprous chloride solution containing sodium chloride passes in the same direction; atmospheric or raised pressure may be maintained in the column 3. The unabsorbed gas, practically free from acetylene and its polymerization products, is separated from the solution in a separator 4 and discharged through an absorption tower 13 (to remove traces of polymerization products) and a meter 14.  The solution from the separator 4 is fed by a pump 5 through a heated spiral 6, a separator 7, and a cooler 8, whence the solution is returned to the column 3.  The mixture of acetylene and its polymerization products from the separator 7 passes through a drying tower 9 and a cooler 10 to another separator 11, from which the liquefied polymerization products are withdrawn and from which the residual acetylene passes through a meter 12 to the holder 1. This procedure may be modified in that (1) the gas may be led in counterflow to the solution in the column 3, (2) the solution may be circulated by the gas stream, on the mammoth-pump principle, instead of by the pump 5, and (3) the acetylene or gas containing acetylene may be introduced wholly or partly into the hot cuprous salt solution withdrawn from the separator 7 before the solution enters the cooler 8; when the regeneration of the solution is effected by reducing the pressure it then becomes necessary, in applying this modification, to heat the solution after it leaves the separator 7.  Examples illustrating the operation of the plant shown are given.
