Abstract: 745,303. Cooling dynamo-electric machines. ENGLISH ELECTRIC CO., Ltd. May 14, 1954 [May 15, 1953], No. 13679/53. Class 35. In a machine with hollow rotor conductors, coolant apertures are provided in the end winding portions at both ends of the machine, the end windings being in enclosures partitioned to provide circumferentially adjacent inlet and outlet regions for the coolant which may be hydrogen. As shown in Fig. 1, a partial developed plan of the rotor, 10 being the core, partitions 18 subdivide the end winding enclosures into outlet regions 20 and inlet regions 19, gas being fed into the latter through apertures 24, thence into apertures 21 in the conductors which are disposed side-by-side in pairs 11a, 11b in the slots. Each aperture 21 is partitioned to cause the gas to take both the possible paths through the conductor, and these apertures are so positioned relatively to the partitions 18 that the gas flows in opposite directions in each pair of conductors. Fig. 9 shows a modification applicable to conductors arranged singly, the gas flow being as indicated by the arrows. The gas may be circulated in a closed circuit including coolers over which is also circulated gas passed over the stator windings, at least three fans being used in the machine.

Title: Improvements in or relating to traffic signalling systems
IPC: G08G1/081
Filed: 1960-04-25
Abstract: 892,571. Road signals for controlling traffic. SIEMENS & HALSKE A.G. April 25, 1960 [April 23, 1959], No. 14444/60. Class 118. In a traffic light control system a first stepping register ZS1, or ZS2, Fig. 1a grounds sequentially the terminals 1 to 100, or 1 to 60, respectively (depending upon the length of cycle chosen by operation of ps1 or ps2) at onesecond intervals, the ground in each case being extended via a programme generating crossconnection field PG to one or more of the terminals 1/1... 1/10, 2/1. . . 2/10, 10/1. . . 10/10. A second stepping register V scans these terminals cyclically and extends each to the relevant ones of ten X and ten Y conductors, these being indicated by the numbers on the left and right of the oblique stroke in the designation of each terminal. Two relay chains JDx and JDy, Fig. 1b are driven by a third stepping register and cause relays JX and JY to send pulses on the x and y conductors to the traffic light locations, the X and Y conductors marked determining the number of pulses sent by stopping the operation of the JDx and JDy chains. At the locations the reception of the pulses effects the lighting of the required lights. Control station equipment.-The stepping registers ZS1 and ZS2 are driven at one step per second by the generator TZ, the choice of programme is effected by closure of contact ps1 or ps2, and assuming the former to be closed, the contacts t1 to t100 are sequentially grounded at one second intervals. The stepping register V is driven at 500 steps per second by generator TV1 until ground is encountered via a closed contact such as V1, whereupon TU pulls up and the generator TV2 drives V at 500 - steps per second until an unmarked contact 12. is reached, the register continuing to be driven in like manner. During the period that a marked contact is closed ground is extended via the relevant X and Y conductors to the correspondingly marked circles in the relay chains JDx and JDy. The chains JDx and JDy receive positive pulses via contacts ti of generator TJ operating at 250 c.p.s., and, considering the JDx chain, as soon as one of the X conductors is grounded relay Z1 operates when next ti is in its left-hand position. If the marked conductor is the nth the first n relays operate in succession, no operating ground being available for the (n+ 1)th relay. Each time a relay of the chain operates, JX is energized in series with its second winding and delivers a pulse to the x conductor. Operation of the JDy chain and JY is similar. Equipment at traffic light location.-The pulses received over the x and y conductors step the 10-point uniselectors Ex and Ey, respectively, Fig. 2, thus closing that contact of the 10 X 10 matrix Sch which corresponds to the energized ones of the windings X1 to X10 and Y1 to Y10. Traffic lights Sg1 are controlled by relays Rt1, Ge1 and Cr1 actuated via bus-bars a, b, c, d and e to light the amber, red, amber and red, green, and amber and green lamps, each relay or relay combination holding until the next is - energized.

Title: Preparation of mixed metal oxides
IPC: C04B35/491
Filed: 1966-04-01
Abstract: <PICT:1112187/C1/1> Mixed metal oxides are prepared by treating an acid solution of the metals in the correct proportions with ammonia at pH 8, and washing, drying and heating the precipitate to form a ceramic. Examples given are a PbZrO3-PbTiO3 mixture and ferrates such as PbO. 6Fe2O3, BaO.6Fe2O3 and SrO.6Fe2O3.  Precipitation is carried out in the example from nitric acid with the PbO-ZrO2-TiO2 system. TiCl4 is dissolved in 2% HCl solution and ZrOCl2.8H2O added in the correct proportion. The metal compounds are coprecipitated, washed free of chloride ions, and dissolved in dilute nitric acid.  Lead nitrate solution is added to this mixture to give amounts of metal corresponding to the formula xPbZrO3.(1 - x) PbTiO3 where 0.5\sEx\sE0.7. Other methods of preparing this solution may be used, and additives such as Fe, Cr, Sr, Ta, Ce, Co, Ni and Nb added. Precipitation is carried out in the apparatus as shown in Fig. 4. The inner vessel 11 contains ammonia solution at pH 8 and is warmed to 50-60 DEG  C. by water jacket 17 heated by steam pipes 14. The nitrate solution enters through nozzle 20 and by means of air under pressure through 21 is atomized on to the surface of the ammonia. The precipitate collects on the bottom of the tank and is drawn off as a slurry through pipe 27.  The solution is stirred continuously by stirrer 18 and the ammonia concentration is kept constant by a mixture of NH3 gas and N2 (in ratio 1 : 1) which enters the solution through a spray outlet on the end of pipe 27.  CO2 + N2 mixtures may also be used with the NH3 : N2 mixtures to help the precipitation. The precipitate is washed with demineralized water which may contain dilute ammonia, either by decantation or filtration.  It may then be spray dried, vacuum dried at various temperatures, oven dried at various temperatures, or dried by displacing the water by methanol and then the methanol by ether.  The dried precipitate is heated to about 650 DEG  C. to form a ceramic.
