Title: Improvements in or relating to self-priming centrifugal pumps
IPC: F04D9/02
Filed: 1945-04-24
Abstract: 598,114. Centrifugal pumps. LAUCHENAUER, H. April 24, 1945, No. 10330. Convention date, June 13, 1944. [Class 110 (i)] A centrifugal pump P is rendered self priming by the provision of an air separator L, located on the pressure side of the pump P, and branching off the pressure pipe D, so as to take part only of the volume discharged (except during priming) and to form together with the branch pipe 1 a path to the suction side of the pump P, and a suction ejector having its nozzle 2 connected to said branch pipe 1. An additional suction ejector nozzle 4 may be inserted in the ejector line, a pipe 5 connecting the nozzle 4 to the pressure side of the pump at 6, thus producing a decrease in pressure on the pressure side of the pump rotor and a consequent reduction in load on the thrust bearing K. The connection between the air separator L and the pressure pipe D may include a grating 12 provided with a stripper device 14, 15, or it may be of the form shown in Fig. 8, this latter construction producing a suction pressure opposing that caused by the nozzle 2 thus reducing internal circulation of fluid through the air separator L and pump P during normal working.

Title: Improvements relating to nuclear reactors
Inventor: SCOTT JOHN ANTHONY
IPC: G21C7/00
Filed: 1962-03-19
Abstract: 974,129. Nuclear reactors. ENGLISH ELECTRIC CO. Ltd. March 19,1963 [March 19, 1962], No. 10401/62. Heading G6C. A nuclear reactor includes a moderator core in which are parallel fuel channels containing fuel elements parallel to which is arranged a plurality of longitudinally-extending neutron-absorbing means over at least part of the depth of the core, the neutron-absorbing capacity of which means is greater in the longitudinal centre portion thereof than in the end portions thereof. Such a means is shown in Fig. 2, a number of stainless steel tubes 16 of equal length and external diameter but of different thicknesses giving masses in the ratios of 0.83: 1. 24: 1. 24: 1. 24: 0. 54 being supported on a graphite block 17 in the channel 15 of a cylindrical graphite core 10, there being a space 18 at the top of the channel. The resulting variation of neutron flux with channel height is shown in Fig. 3, curves 30 and 31 showing the variation in the vicinity of two absorber channels 15, one near the centre of the core 10 and the other just within the periphery of the central region of the core (which region contains the channels 15 between the fuel channels) respectively,while curve 32 shows the variation over the height of a fuel channel just outside the central region. The broken curve 33 shows, by way of comparison, the variation over the height of a similar core in which the channels are stacked to their full depth with neutron-absorbing elements, each of mass unity compared with the masses of the elements 16. Fig. 5 shows the radial variation in the maximum fuel element temperature reached in any given channel for a particular set of conditions such as coolant flow rate, the curve 51 relating to the core 10 and curve 50 to the same core as does curve 33 in Fig. 3. For both curves, the same heat is assumed to be produced per unit time by the fuel in the centre channel of the core. The region 14 is that part of the core in which the neutron-absorbing elements are situated. It is seen that the neutron flux may be increased if the arrangement of Fig. 2 is adopted, without modifying the design of the core to allow for higher temperatures, until the maximum temperature has risen by the amount "t" indicated in Fig. 5. The variation in maximum fuel element temperature is then as shown by the curve 54. In an alternative arrangement, each fuel element has longitudinal splitters to which are attached stainless steel wires which act as neutron-absorbing means in place of the elements 16 in channels 15. The masses of the wires attached to consecutive fuel elements will be in the same proportions as those of the elements 16.

Title: Improvements relating to telecommunication exchanges
Inventor: REANEY DONALD
IPC: H04M3/424
Filed: 1969-03-27
Abstract: 1,270,602. Automatic exchange equipment. PLESSEY CO. Ltd. 12 June, 1970 [27 March, 1969], No. 10477/69. Heading H4K. A telephone exchange includes call control equipment whereby a designated subscriber can make a distinctive signal to cause the number of a wanted but busy subscriber to be booked and repetitively tried when the designated subscriber is not busy. When the designated subscriber receives busy tone on a call to the wanted subscriber he operates a push-button which operation is detected at 1 to connect the subscriber to number store 3 through contacts 2, busy his line and open contacts 4 to break the connection to the exchange line equipment. Timer 21 is also started by operation of bi-stable C. The wanted number is dialled into store 3, using a digit distributor 5 if required, after which the subscriber goes "on hook" to restore contacts 2, 4 and remove busy tone from his line. The designated subscriber can now make or receive calls normally but whenever his station is "on hook" one input of AND gate 7 is up. The other two inputs of AND gute 7 are from an interval timer and from the exchange equipment to denote a free register respectively. When all inputs are up bi-stable A operates to seize a register and simulate calling conditions on the designated subscribers line. After a time delay contacts 6 close to connect register N to number store 3 and the number is non-destructively read so that the path to the wanted subscriber is set up in the normal way. Ringing current is reverted to the designated subscriber who by answering completes his loop to operate a loop detection relay which trips the ringing supply and restores bi-stable A. When the wanted subscriber answers bi-stable C is restored to clear store 3 and zero timer 21. If a path to the wanted subscriber is not established or he is busy bi-stables A and B are restored. If an unobtainable tone is obtained the designated subscriber is rung and store 3 cleared before timer 17 releases the connection. If a connection is made but neither subscriber answers the ringing continues unless a timer releases the connection. To cancel the call the designated subscriber goes "off hook" and presses the button.
