Title: Linear electric motor systems
IPC: H02K41/03
Filed: 1973-06-01
Abstract: 1449469 Linear motors; Control of brushless motors C S J LAMB and K B WYLD 24 May 1974 [1 June 1973] 26165/73 Headings H2A, H2J A D.C. linear motor comprises at least three force producing components, including at least one coil group and at least one magnetic field system and has means for providing the force for predetermined periods as well as ensuring a continuous driving force along an associated linear track. In the train propulsion system of Fig. 3, armature coils are mounted on an overhead, permeable rail 1 and are connected in parallel to a rectified A.C. source. Electromagnets 15, 16 on the vehicle 17 are energized as shown. Current in alternate coils e.g. 10, 11 is provided for predetermined periods and is in opposite directions to provide a driving force to the magnets 15, 16. As the train moves, magnetic sensors S101, S102 etc. (preferably of the magneto-transistor type) detect the approach of the poles N1, S1 etc. and reverse the current polarity in the coils, thus continuing the driving force.  Control circuit, Fig. 5 Adjacent coils 10, 11 are energized from a supply G (A.C., rectified D.C. or battery D.C.) through a thyristor full-wave rectifier T1-T8 under the control of the sensors S101-S112, which respond to the approach of particular polarity fields and switch pairs of thyristors T1, T2 or T3, T4 to excite the windings for a predetermined time, with the correct direction of current. Enabling signals on lines D from a central control ensure that only coils in the vicinity of the train are energized. The delay between the receipt of enabling signals and the production of sensor outputs indicates the deviation of the train from its desired position and may be used to control the train speed by varying the thyristor triggering angle or the timing of the enabling signals. For high acceleration, all the coils would be used, otherwise some may be omitted. In track portions where acceleration or braking is required, the coils are more closely spaced than in constant speed stretches. Braking may be obtained by providing further sensors to control the thyristors to energize coils producing a reverse force on the train. Mechanical braking may be used. In alternative arrangements, the coils may be mounted on the train, with stationary field systems and in either case, the coil current may be constant in direction with the polarity of the field systems being switched for a continuous driving force. Members 15, 16 may have superconducting windings or be permanent magnets. The sensors may be mounted on the train instead of the track.

Abstract: 976, 571. Radiation detector circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 20, 1961 [July 29, 1960], No. 26606/60. Heading G1A. [Also in Division G6] Apparatus for detecting a sudden increase or decrease in the mean rate of occurrence of consecutive events at random comprises signal means responsive to each event to provide a signal for each event, means for integrating the signals, and means for comparing a short-term integral of the signals with a long-term integral of the signals. The apparatus may be applied to measurements of the neutron flux of a nuclear reactor to detect an increase due to an excursion whilst ignoring statistical fluctuations or a slow increase or decrease caused by normal changes of a reactor to detect a burst fuel element. Pulses corresponding to each event may be fed to a diode pump circuit as shown in Fig. 3 so that the output voltage is proportional to the average rate of the pulses for a period corresponding to the time constant of the condenser C s  and resistance R s ; this output voltage may be compared with that of a similar circuit having a longer time constant to give an alarm if the instantaneous rate exceeds to the mean rate by a predetermined factor. In Fig. 5 an amplifier V1a inverts the output V s  of a diode pump circuit with a gain of 1. 2. The inverted output is integrated, by condenser CV1 and resistance R2 which have a relatively long time constant, and mixed at the grid of V1b with the original diode pump output and a fixed bias applied at RV1; the valve V1b acts as an anode-follower. A plurality of circuits having different time constants may be used to cover the range of excursion periods that may be expected; thus a number of circuits similar to Fig. 5 may each be connected through a diode to a common line leading to a discriminator; the first output to go positive causes its diode to conduct and operate the discriminator.

Title: Improvements in or relating to the reduction of the permeability of structures and granular masses
IPC: C09K17/06
Filed: 1934-09-17
Abstract: The permeability of structures is reduced, or granular masses are consolidated, by supplying to the interstices thereof calcium bicarbonate in aqueous solution and lime-water, the bicarbonate and lime reacting to form calcium carbonate.  The solutions may be allowed to flow into the structures or granular masses, or may be forced under pressure through pipes.  Carbon dioxide also may be used.  Thus, lime-water is forced through a pipe extending to the base of a concrete raft resting on waterlogged granular masses, then carbon dioxide is forced in, then an excess of calcium bicarbonate solution is forced in.  Then lime-water and carbon dioxide are supplied in succession until no more can be forced in. Finally, the supply pipes are driven into the granular substratum and the process is repeated.  Flue-dust, fine silty sand, finely-ground brick-dust or the like may be added to the solutions to assist in filling the interstices.  In treating granular masses only, to retain or guide the solutions, sheet piling may be driven in or a blanket of asphalt or clay may be spread thereover. Specification 416,391 is referred to.
