Title: Improvements in or relating to a process for removal and recovery of acetylene from gas mixtures
IPC: C07C7/11
Filed: 1946-03-27
Abstract: Acetylene is separated and recovered from moist gas mixtures by cooling the mixture to between 0-40 DEG  C. in the presence of a water-miscible ketone having a freezing point of - 40 DEG  C. or lower and which is present in an amount only slightly in excess of that required to absorb substantially all the water condensed by said cooling, draining off the solution so formed and then absorbing the acetylene from the gas mixture by excess liquid ketone at the same or a further reduced temperature.  Ketones specified include acetone, methyl ethyl ketone, and diethyl ketone.  A preliminary partial drying may be effected by cooling to a temperature slightly above 0 DEG  C.  The acetylene is recovered from the ketone by heating, and the ketone may be recycled for further use.  A mixture of two or more ketones may be used.ALSO:Ketones-acetone, methyl ethyl ketone and diethyl ketone are used to separate acetylene from moist gas mixtures.  Initially, the mixture is cooled to between 0 DEG  and -40 DEG  C. whence the moixture condenses and mixes with the ketone, the resulting liquid being drawn off.  The amount of ketone used is only slightly in excess of that required to absorb all the water. Finally, the acetylene is absorbed from the dry gas mixture by excess ketone at the same or a further reduced temperature.  A mixture of two or more ketones may be used.

Title: Improvements in and relating to dynamo electric machines
IPC: B60L15/00
Filed: 1925-04-14
Abstract: 232,258. British Thomson-Houston Co., Ltd., (Assignees of Hanna, M. R.). April 14, 1924, [Convention date]. Rotary transformers; exciting.-In an electric distribution system employing a continuouscurrent transformer, the load for the transformer includes a shunt motor having additional field windings arranged to have no substantial magnetizing effect in normal operation, but serving to protect the motor from the effects of surges of the potential applied to the transformer. In the application to electric locomotive &c. equipment, a transformer DM, preferably of the type described in Specification 5974/08, supplies the motor 10 of a motor-generator set 10, 12 which generates low-voltage current for the operation of lamps &c. A shunt characteristic is imparted to the transformer by means of a winding 14 connected across the lower potential brush 15 at the motor end M and the lower potential brush 16 at the generator end G. The transformer is also provided with opposing series field windings 17, 18 as described in the prior Specification. The motor 10 has a shunt field winding 11 and two opposing series windings 19, 20 which form a connection between the lower potential ends of the transformer series field windings 17, 18. In the event of the trolly leaving the wire 13, the transformer DM and motor 10 act momentarily as generators and tend to send a large current through a low-resistance circuit comprising the traction motors 21, 22. The current in the windings 17, 19 is consequently reversed and the series fields in both transformer and motor 10 oppose the shunt fields and the voltage generated is reduced. If the trolly again makes contact with the wire there will be a momentary rush of current owing to the reduced speed of the transformer and motor. In consequence the current in the windings 17, 19 will assume the directions shown by the arrows, and the currents in the windings 18, 20 will have directions opposite to those shown. The series fields therefore assist the shunt fields and act to limit the initial rush of current.

Title: Transducer
IPC: G01L1/22
Filed: 1955-04-04
Abstract: 774,328. Electric control devices. LI, Y. T., and LEE, S. April 4, 1955 [April 14, 1954], No. 9851/55. Class 40 (1). A strain gauge transducer comprises a central spindle, a supporting plate through which the spindle passes, two pairs of rockers mounted for slight pivotal motion on the plate and connected to the spindle, one pair of rockers being disposed on each side of the plate, and strain gauge resistance windings carried by the two pairs of rockers and adapted to be differentially strained upon motion of the spindle. The transducer may be used for measuring force, pressure or acceleration producing rectilinear motion of the spindle. In Fig. 2, applied pressure on diaphragm 52 moves spindle 6 so that upper rockers 18, Fig. 1, pivot outwardly to increase the tension on the resistance windings 30, 32, Fig. 4, whilst the lower rockers 18 pivot inwardly to decrease the tension on the resistance windings 34, 36. The two pairs of resistance windings 30, 32 and 34, 36 are disposed to form a D.C. fed bridge, Fig. 3, so that indicated bridge unbalance measures the applied pressure. The apparatus has inherent temperature compensation since all four of the rockers 18 are rocked equally due to expansion and contraction and the bridge remains in balance. The resistance windings 30, 32 and 34, 36 and associated rockers form part of similar upper and lower unitary assemblies 14, 16. The mounting or supporting plate 8 is fixed to rings 10, 12 from which extend for both assemblies 14, 16 flexible legs 20 into connection with rockers 18 and the latter have inner legs 22 leading to collars 24 secured to the spindle 6. The legs 20 permit limited swings of rockers 18 on rings 10 or 12 and the collars 24 also form stops for the spindle 6. The resistance windings 30 &c. are wound around insulating pins 28 extending through rockers 18 and each winding is anchored under tension to clips 40 (see Fig. 2) on terminal posts 37. The lower unit 16 is mounted so that the plane of the rockers 18 is perpendicular to the plane of the rockers 18 in the top unit 14.

Abstract: 384,166. Multiple-expansion reciprocating engines. AKTIEBOLAGET GÍTAVERKEN, Gothenburg, Sweden. April 6, 1932, No. 9886. Convention date, Nov. 11, 1931. [Class 122 (iii).] In compound and multiple-expansion engines wherein the exhaust steam is utilized in a lowpressure turbine driving a blower, turbocompresser or like pump connected between two subsequent engine cylinders by means of which energy delivered by the exhaust turbine is supplied to the steam between the cylinders, a water separator is arranged in the suction conduit of the pump. The pumps 13, 14 through both ends of the pipes 15, 16 communicate with the two sides of the receivers 7, 8 respectively. One or more separators 17 with drains 18 are arranged between the receivers and the pumps. The receivers are each divided into two compartments by partitions 19, 20 respectively which communicate directly by manually controlled or automatic valves 25. At least the mediumpressure cylinder will work with superheated steam, since the pumps are fed with dry steam. The energy supplied may be utilized wholly or partly for augmentation of the temperature by internal or external frictional or throttling means, or the steam may pass through superheaters in the boiler flues. The turbine 10 may be disconnected and the low-pressure exhaust pass by pipe 9 to the condenser 12.
