Title: Improvements in or relating to fault alarm arrangements for electric communication circuits
Inventor: MCLEOD THOMAS SYMINGTON
IPC: H04B1/74
Filed: 1953-03-09
Abstract: 725,444. Magnetic amplifiers. STANDARD TELEPHONES & CABLES, Ltd. March 9, 1963, No. 6428/53. Class 40 (4). [Also in Group XL (c)] An electric communication system (see Group XL (c)) comprises two indicators which are operated respectively by a magnetic amplifier at different levels of signal output of the system. A detector 30 coupled to the output wave-guide of the system feeds a control current representative of the output signal level to the control windings 37, 40 of a magnetic amplifier and a current is passed through bias windings 38, 41 to neutralize the flux due to the normal control current so that the output windings 36, 39 have a high impedance. Thus insufficient current flows from the A.C. source 46, 47 through rectifiers 42-45 to operate a control relay A. If the control current decreases a predetermined small amount relay A operates. Contacts a3 and a4 operates non- urgent local and remote alarms while contact a1 reduces the bias current of the magnetic amplifier such that relay A releases. This causes the bias current to increase again and accordingly the relay "chatters" at about 5 c/s. Contacts a3 and a4 close before a1 and a2 and the former therefore remain closed so that a steady alarm is given. If the decrease of control current is large, however, the decrease in bias current is insufficient to release relay A and contact a2 remains closed long enough for relay B to operate. Contact b2 switches on a test oscillator which is coupled to the receiver input and provides a signal which if the amplifier is working properly is sufficient to cause relay A and then B to release so that the test oscillator is switched off. The relays therefore are energized again and cyclic operation takes place until the normal input signal is restored. If, however, the amplifier is defective the relays are not released and contact b3 remains closed long enough to operate relay C. Contact c3 and c4 operates local and remote urgent alarms. Specifications 587,664, [Group XL], 653,966, [Group XL (c)], and 675,741, [Group XL (b)], are referred to.

Title: Improvements in traffic signals
IPC: G08G1/095
Filed: 1932-03-04
Abstract: 388,576. Road signals for controlling traffic. BOOR, T. A., Long Street, Ashville, Ohio, U.S.A. March 4, 1932, No. 6614. [Class 118 (ii).] Road signalling-apparatus for controlling traffic comprises a lamp 29, a stationary lamp housing 26, signal windows 17 in an outer housing 10, rotating indicators 42 traversing reflecting windows, a shutter 30 reciprocable over the lamp housing 26, and having pairs of vertically arranged lenses 31, 32, adapted for movement thereover, one of the lenses representing a " go signal and the other a " stop " signal, and means for reciprocating the shutter 30 upon each complete rotation of the indicators 42. The housing 10 may be suspended from a cable by means of a bail 14 and a fastening 16. The windows 17 are arranged in four separate compartments, and are provided with ground glass lenses 18. The rotation of the indicators 42 is brought about by a motor 33 driving a stud shaft 35 on which is mounted a gear wheel 38 meshing with a larger gear wheel 37 revolvably mounted on a shaft 36, which also carries a bevel gear 41 meshing with bevel gears 45 at the extremities of the shafts 43 which carry the four indicators. The reciprocation of the shutter 30 is brought about by an intermittently operated trip mechanism 50. The shutter 30 is attached by,means of a bail 54 to a lever 52 pivoted at 53 to a support 51, a spring 55 being arranged to hold the shutter normally in a raised position. The other end of the lever 52 is attached to a rod 57, which is subjected to intermittent upward and downward reciprocation by being pivotally connected at its lower end to a rotatable crank and crank shaft. Intermittent rotation of the crank shaft is effected by its connection with a geneva gear 62 in the slots 65 of which there moves a pin 59 pivotally mounted at its other end to the rotating gear wheel 37.
Patent GB-803184-A (GB)
Title: Improvements in or relating to the separation of normal paraffins from hydrocarbon mixtures
IPC: C07C7/13
Filed: 1957-02-28
Abstract: In a process for separating a normal paraffin from a normally liquid hydrocarbon mixture also containing branched-chain and/or cyclic hydrocarbons by contacting the mixture in the liquid phase with a solid absorbent which selectively absorbs normal paraffins, the absorbed paraffin is desorbed with a normal paraffin in the liquid phase which contains at least four carbon atoms per molecule and of lower molecular weight than the absorbed paraffin.  Desorbed hydrocarbon is readily separated from any desorbing hydrocarbon by fractionation.  The feed for separation may be a gasoline mixture, e.g. a reformate, and the normal paraffins separated may be subjected to isomerization or other treatment to improve the octane number. Traces of isobutane and lower boiling hydrocarbons are preferably removed prior to the separation by distillation.  Absorption and desorption are both preferably carried out at 80-152 DEG  C. and 13.5-68 atmospheres, the pressure being sufficient to maintain the hydrocarbons in the liquid phase.  The desorbing hydrocarbon may be removed from the absorbent by reducing the pressure.  Normal butane is the preferred desorbing hydrocarbon.  Absorbents which may be used preferably have a pore size of about 5.1   and include the crystalline alumino-silicates of calcium, magnesium, barium, strontium, sodium and potassium.  The calcium compound is preferably heated to remove water of hydration.  In a preferred embodiment separation is carried out continuously by the use of two absorption zones, one being used for absorption while the other is desorbed.

Title: Improvements in or relating to the separatioan of hydrogen from gaseous mixtures containing hydrogen
Inventor: GREGORY SYDNEY ABSELL
IPC: B01D53/22
Filed: 1960-03-01
Abstract: Hydrogen is separated from a gaseous mixture containing hydrogen by passing the gaseous mixture into a diffusion unit comprising palladium or palladium alloy, preferably in the form of one or more tubes or a bundle of tubes, heated to a temperature at which the palladium becomes permeable to hydrogen, and at least a part of the gas rejected at the inlet side of the diffusion unit is employed for supplying heat to the system-this can be achieved by burning the gas with or without auxiliary fuel gas to preheat the main gas stream at a point before the diffusion unit. The gaseous mixtures to which the invention is applicable are those in which the hydrogen content is about 50% and which contain no components deleterious to palladium. The diagram shows an apparatus for obtaining purified hydrogen from cracked ammonia. The gaseous mixture is generated in an ammonia cracker 1, passes to compressor 3, through fitter 4 to remove carbon dust, then to heater 5 where it is heated to 500 DEG  C. in a heated alloy coil 6, and then into a diffusion unit 7 consisting of a bundle of palladium tubes 8 soldered into a header 9 which is flanged to steel shell 10, the latter being independently heated by an electric heating coil 11 to maintain the temperature at not less than 200 DEG C. The purified hydrogen which diffuses through the palladium is collected in steel shell 10 and after passing through cooler 12 is collected from line 13.  The non-diffused gas collects above header 9 and after passing through cooler 14 is fed to gas burner 15 to which additional combustion gas, e.g. town gas, propane or butane, may also be supplied from 16.  It is necessary to purge both sides of the palladium diaphragm with an inert gas or inert gas mixture, during the heating up and cooling down and for this the main supply of feed gas is cut-off or diverted.  The shell side 10 of the diffusion unit is purged by a supply of inert gas from line 19, the gas after traversing the shell passes through cooler 12 and then line 24 to stack 22.  The header side 9 of the diffusion unit is purged by a supply of inert gas through line 20, such gas passing through 3, 4, 6, header 9, waste gas cooler 14 and pipe 21 to stack 22. The shell 10 of the diffusion unit may be in close thermal association with heater 5 to transfer part of the heat, otherwise dissipated from the heater, to the diffusion unit. <PICT:0972093/C1/1>
