Patent GB-1286033-A (GB)
Title: Improvements in or relating to telecommunication line fault location systems
IPC: H04B3/44
Filed: 1970-01-15
Abstract: 1286033 Repeater fault location SIEMENS AG 15 Jan 1970 [16 Jan 1969] 2008/70 Addition to 1155653 Heading H4R In the line fault location system of parent Specification, in which the voltage supplied to the line from a constant current source to power the repeaters is monitored and the source changed to constant voltage if a line fault causes the voltage to tend to rise above a predetermined value, the voltage supply is reduced to a low measuring value if the output current falls below the minimum value necessary to keep the repeater amplifiers operational, the supply voltage being restored as soon as the load impedance presented by the system falls within a predetermined operational region. As shown each repeater includes a switching stage, S1 or S2, which inserts a resistance across the line when the current fed to the succeeding line section falls below a predetermined value. The value of the shunt resistance is such as to ensure that switching stages prior to the last stage before a fault, U, causing the circuit interruption, are operated while the last stage is not operated by the fault resistance Ru, produced for example by ingress of moisture at a line break. The arrangement ensures powering of all the repeaters up to the last before a fault to enable the location of the position of the fault.

Patent GB-371855-A (GB)
Title: Improvements in or relating to apparatus for testing high power electrical equipment
IPC: G01R31/333
Filed: 1931-01-21
Abstract: 371,855. Dynamo-electric machines. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Jan. 21, 1931, No. 2051. Convention date, April 15, 1930. [Class 35.] Exciting.-An apparatus for testing high power electrical equipment comprises a generator arranged to be short-circuited and to subject the equipment under test to the short-circuit current, and means are provided to supplement the generator excitation and so counteract any field weakening resulting from the short-circuit current. Rapid fading away of the short-circuit current is therefore prevented. Fig. 1 shows a generator 2 which can be short-circuited by an oil switch 4 undergoing test. A resistance 8 in the circuit of the separately excited field winding 3 is adapted to be shunted by a switch 9 when the switch 4 is closed. In Fig. 2, a weakly saturated transformer is arranged with its windings 10, 11 in series with the armature 5 and shunt field 6 of the exciter whereby an additional electromotive force is generated in the exciting circuit 3 when the switch 4 is closed. In a further modification, an additional series exciter in the exciting circuit has its field winding normally shunted by a switch which is opened when the testing generator is short-circuited. Alternatively, the main exciter 5, Fig. 4, may have an additional series winding 15 normally shunted by a switch 12 which is opened when the test is commenced. With this arrangement, the short circuit current drops somewhat from the maximum, and to avoid this, the test may be carried out in a reverse manner. A switch 16 in the main exciting circuit 3 is kept open while the field 6 of the exciter 5 is energized. The switch 4 is closed and the test is started by closing the switch 16, the switch 12 being opened, and the short-circuit current increases from zero to a maximum, at which the switch 4 may be opened. A flywheel may be provided on the shaft of the exciter. The exciting current during short-circuit should be about five times that required at no load.

Title: Electric digital data storage system
IPC: G11C21/00
Filed: 1968-01-15
Abstract: 1,201,432. Electric digital data storage. INTERNATIONAL BUSINESS MACHINES CORP. 15 Jan., 1968 [16 Jan., 19671, No. 2109/68. Heading G4C. An electric digital data storage system comprises a circulating loop data store and a shift register arranged to execute serial data transfer to and from the loop and to execute parallel data transfer to and from the system, wherein the data circulating in the loop contains a control field the contents of which are sensed and used to determine the time to stop a data transfer from the loop to the shift register or the time to start a data transfer from the shift register to the loop. A central processor and a peripheral device communicate in both directions via a buffer including a delay line (magnetostrictive, or magnetic drum). The delay line can hold a 15- bit data field and 5 control bits. In general not all of the data field is occupied, the position of the end of the occupied portion being specified by the control bits which also specify when transfer with the processor is possible. The bits from the delay line output are gated into respective flip-flops in a "base register" then serialized by gates and passed via a shift register in a "base write control" block back to the delay line input. Bits from the peripheral device can be appended to the end of the circulating bit stream or bits can be passed to the peripheral device from the beginning of the stream, serially by bit in each case, part of the shift register in these cases being, by-passed by the circulating bits to shift them along, the control bits being up-dated. The delay line output is also shifted into a second shift register at the right time as determined by the control bits. The second shift register can receive data from or send data to the processor, parallel by bit. The second shift register can also supply data serial by bit to the delay line input via the shift register in the "base write control" block, a tag bit 1 being inserted in the second shift register after the last bit and shift out being terminated when the tag bit reaches the last stage (by detection of the pattern 00 ... 001). The system can handle several different byte lengths.

Title: A method and apparatus for the automatic packaging of fluid or incoherent material
IPC: B65B61/26
Filed: 1963-01-17
Abstract: 1,026,756. Packaging-machines. NEW WANGUARD S. a.r.L. Jan. 17, 1963 [Jan. 20, 1962], No. 2168/63. Heading B8C. A method of continuously packaging fluid or incoherent materials comprises the steps of extruding a plastics tube 7, filling the tube from a nozzle 9a, forwarding and nipping the tube by means of drag rollers 11, 11a and sealing the filled tube by means of electrodes 25, which may be of the high-frequency type. Granular or powdery plastics material from an extrusion press 2 enters an extrusion head 3 from whence tube 7 egresses and is initially cooled by a coldair blower 12. Axially of head 3 are positioned the material feed tube 9a connected to a tank 9 via a valve 9c, adjustable by means of a metering device 10, and a coaxial tube 8a which may supply inert gas. A carriage 16 slidable on guides 15 is reciprocated vertically by a cam 17, its downward speed being substantially equal to the rate of extrusion of the tubing. To the carriage 16 is fixed a platform 24 which carries the electrodes 25 and a cutting mechanism 29. Adjustable expellers 34, 35 mounted on the electrodes remove upwardly excess material before the tube is sealed. An outlet mechanism, Fig. 8 (not shown), receives on an intermittently operating band conveyer 109 a drain of packages filled and sealed as above. Transverse members 107 on the conveyer have longitudinal slots 108 and are positioned to be adjacent the welds between the packages. The packages are brought in turn beneath a printing assembly supported on frame members 100b by the operation of piston stems 119, 119a and ratchet gears 122, 122a. Hydraulic cylinders 123, 129, Figs. 9 and 10 (not shown), on a cutting mechanism and the printing assembly respectively, are then caused to operate at the same time, a knife 126 being lowered to sever a package, the tip of the knife entering the slot 108 of a crossmember 107 held in position by movable bars 120, 120a.

Title: Manufacture of phosphine
Inventor: PALMER MALCOLM GEORGE
IPC: C01B25/06
Filed: 1961-01-19
Abstract: <PICT:0943281/C1/1> Phosphine is manufactured by bringing white phosphorus into contact with an amalgam of mercury with Zn or Cd in the presence of an aqueous acid medium.  The proportion of Zn in the amalgam may be up to 70%, but the preferred concentration of Cd or Zn is up to 5%. Acids used may be sulphuric, acetic, hydrochloric, phosphoric or phosphorous acids. Amalgam is poured into electrolysis vessel 2 and flows through tube 4 into reaction vessel 1 equipped with stirrer 13 and heater 15 and the vessel is then purged with an inert gas. Aqueous 1-10 M acid is poured into vessel 2 and transferred via siphon 6, 3, 5 into vessel 1, though the pH of the aqueous acid may be as high as 5. Molten phosphorus in funnel 10 falls dropwise through the acid, which is maintained at refluxing temperature, and spreads in a thin layer over the surface of the amalgam; phosphine is led off through outlet 11.  To regenerate the amalgam, vessel 2, containing stirrer 14 and cooling oil 16 is lowered and amalgam of depleted Cd or Zn content flows into it via tube 4. The acid medium is siphoned via 5, 3, 6 into vessel 2 and then electrolyzed between platinum anode 19 and the mercury or amalgam cathode in contact with cathode connection 20 until hydrogen evolution commences at the cathode to return Cd or Zn from the acid medium to the amalgam.  Vessel 2 is then raised and the cycle of operations recommenced.  Alternatively, the amalgam may be allowed to fall dropwise through a layer of white phosphorus floating on a column of acid medium; each drop picks up a layer of phosphorus and then falls through the acid column. The Cd or Zn content may be replenished by substituting fresh amalgam or by adding Zn or Cd to the amalgam during or after the reaction.  The process may be performed continuously.
