Title: Method of and apparatus for Electrically Encoding Information
Inventor: EDGE GORDON MALCOLM
IPC: H04Q3/00
Filed: 1965-11-06
Abstract: 1,150,371. Encoders. STANDARD TELEPHONES & CABLES Ltd. 6 Feb., 1967 [6 Nov., 1965 (2)], Nos. 45984/65 and 45985/65. Heading G4H. [Also in Division H4] Apparatus for encoding information includes a pulse generator 1 (Fig. 1) driving a constant current generator 2 and a memory element, e.g. a capacitor 4, which is charged to or discharged from an energy level determined by the signal to be encoded and then charged or discharged by the pulses from generator 2 so that the energy level changes in a number of equal discrete steps to give an output in accordance with the input signal which it is required to encode. In the embodiment of Fig. 1 the capacitor 4 is initially charged to its maximum value by the constant current generator 2 and then a switch 8 is closed to charge it to a value corresponding to the voltage between terminals 9 and 10. When the switch is opened clock pulses from the source 2 again recharge the capacitor to its maximum value and an output is obtained at terminals 6 and 7 comprising a pulse train representing the number of pulses required to recharge it fully. If the apparatus is for use in a telephone system a plurality of such memory systems may be included with read in being controlled, for example, by push buttons and read out by ring counters. In the embodiment of Fig. 3 the output from the constant current generator 31 is inhibited during read in by a switch 37 and a gate 36, the gate 36 remaining inhibited until the switch 37 is operated to allow pulses to be applied to the memory system and so cause a further gate 40 to be enabled. The diode 33 through which the input to the capacitor 34 is fed may be replaced by a transistor or a field effect transistor (Figs. 4 and 5, not shown). In a further embodiment (Fig. 6, not shown) a Zener diode (75) which is connected to the base of the transistors (72) is connected across the memory element. A plurality of memory units 96, 97, 98, 99 (Fig. 8) may be connected to a common constant current source 91 inputs from a keyboard being sequentially fed to the memory units under the control of a ring counter 105, 106, 107, 108 each stage of which controls read in to one of the memory units and read out of the preceding memory unit. In a memory circuit of the type shown in Fig. 9 the unit is selected when a control pulse is supplied from the activated counter stage to terminal 127, the input signal to be encoded being fed to terminal 128.

Title: Improvements in or relating to the sulfonation of fatty acids
IPC: C11C3/00
Filed: 1964-11-16
Abstract: <PICT:1034989/C2/1> Fatty acids are sulphonated with 100% SO3 by atomizing the fatty acid, preferably in a solvent therefor, discharging the resulting fine particles through a confined body of SO3 vapour, collecting the sulphonated fatty acid and separating the solvent therefrom.  Suitable fatty acids are C12 to C22 fatty acids such as stearic, palmitic, lauric and myristic acids. Suitable solvents are those which will maintain the fatty acid in a liquid state at the reaction temperature such as perchloroethylene or CCl4. A portion of the liquid product may be recycled to the atomization and discharge steps. Preferably, the fatty acid in its solvent is heated to about 125-160 DEG  F., and the liquid atomized within a chamber containing SO3 vapour, the fine fatty acid particles being discharged at a high velocity through the vapour so that contact time is very short.  The process may suitably be carried out in the apparatus shown in the Figure wherein fatty acid, dissolved in a solvent, is heated in a feed tank and fed by pump via a flow control to a rotor casing (12) where the liquid acid is discharged between spaced discs forming a rotor head (16).  The rotor head is driven by motor (14) and the liquid enters the channel of the rotor mechanism via line (15).  The SO3 vapour is introduced through a line (17) into a distributer (18) having openings through which the vapour is discharged to substantially fill the upper portion of the closed shell (19).  The SO3 vapour forms a body about the rotor head (16) and the vapour exits through an outlet pipe (21) having its opening above the liquid acid body (22).  The liquid mist, on emission from the rotor head (16), passes through the SO3 vapour and impinges on the walls of the shell (19), from which it flows to the liquid body (22) therebelow.  The heat of reaction is removed by a cooling water jacket (23).  Liquid may be recycled from the liquid body (22) via line (24) by means of pump (25) and through flow control (26) back to the feed line (15).  The product may be withdrawn through outlet (27) and pipe (28) to an ageing tank which is preferably maintained at an elevated reaction temperature and transferred to a crystallizer. Examples are given for the sulphonation of stearic acid.

In friction welding, flash is removed whilst still hot, immediately the upsetting stage is completed, by high impact shearing. As shown, a bar 10 held in a non-rotatable chuck 12 is welded to a bar 11 held in a rotatable chuck 13. An annular shear blade 14, mounted on a plate 19, embraces the rod 10. The plate 15 is supported on rods 16 slidably in the frame 18 which carries the chuck 13 and is normally urged away from the frame 18 by springs 17. The blade 14 is actuated by a hammer mechanism 24 through an anvil 22, rods 20, slidable in the frame 21 which carries the chuck 12, and an annular member 19. The frusto-conical front face of the blade bursts the annular flash removed by the blade. Alternatively the blade may have a diametral tooth on the front face for splitting the annular flash removed in two. For removing internal flash where two tubes are welded the head of a plunger slidably mounted in one of the chucks is formed as a shear tool. The plunger is normally urged away from the weld area by springs and carries an anvil at its rear end.
