Title: Rotary closed rankine cycle engine
IPC: F01K11/04
Filed: 1972-12-08
Abstract: 1389900 Rotary Rankine cycle engine; spiral working fluids E I DU PONT DE NEMOURS & CO 8 Dec 1972 [10 December 1971] 56726/72 Heading F4A [Also in Divisions H2 and F1] A rotary closed Rankine cycle engine comprises an annular boiler B rotatable about its axis to maintain an annular liquid body about the inner periphery, the vapour produced when the liquid is heated being passed through an expander, e.g. a turbine T to extract work and into a condenser C coaxial with the boiler and rotable therewith as a unit, the condensate being returned to the boiler;and a gear train within the boiler-condenser unit connecting it to the expander to be driven thereby. In Fig. 1, a turbine 30 drives the boiler-condenser unit via sun gear 50, gears 51 mounted on a fixed spider 5 and an annular ring gear 52. The condenser C comprises circumferentially spaced tubes 41 with fins 40 mounted between plates 12 and 44. for rotation about bearings 14, 15, condensate from tubes 41 passing via chamber 48 and tubes 49 to the boiler. The side of the boiler B remote from condenser C is mounted on shaft 8 rotable in bearing 9 and having a power take off point 59. A starter motor M drives the boiler-condenser unit to bring it to its operating speed before the boler is heated. Different gearing arrangements may be used, Figs. 5-8 (not shown) in which one or more of the gears is mounted on the non-rotating shaft 16 (or 16a, 16b). In Fig. 9, the planetary gears 95 are mounted on a spider 99, which is held stationary by the effects of permanent magnets 106, 107, which act upon one another, the magnets 107 being located on fixed support 108 and magnets 106 being on member 104 rotatable with shaft 100 rigid with spider 99. The permanent magnets 107 may be replaced by electromagnets 107a, Fig. 12, whose coils are supplied via a rheostat (129) Fig. 13 (not shown) to vary the holding torque applied to spider 99. Allowing rotation of spider 99 during operation of the starter motor reduces the load on this motor. The housing 119 is vapour proof and non-magnetic. The spider 99 may be prevented from rotating by a pendulum (130) Fig. 14 (not shown) attached to the shaft 100 instead of using magnets. Additional energy storage capacity may be provided by a flywheel (134) Fig. 16 (not shown) attached to the shaft 33 on which the turbine is mounted. The working fluid used in the boiler may be trichlorotrifluorobenzene.

Title: Accumulator monitoring apparatus
IPC: H02J7/00
Filed: 1970-12-22
Abstract: 1,272,030. Monitoring the state of charge of a battery. COMPAGNIE GENERALE D'AUTOMATISME. Dec.22, 1970 [Dec. 22, 1969], No. 60813/70. Heading G1U. The state of charge of a battery 4, Fig. 1, is monitored by periodically shunting the battery by a resistor 14, thereby causing a pulse of known current I to flow through the battery in addition to the normal load current i of the battery, and by comparing the resulting change in potential across the battery with a reference potential. As described energization of a coil 10 closes a switch 11 thereby causing a monostable unit 12 to close a further switch 13, and hence to connect the shunt resistor 14, for a duration shown by waveform S 12 , Fig. 2. The monostable 12 also produces a further pulse, shown at S 16 , Fig. 2, via a delay 15 and a further monostable 16. This pulse S 16  is applied to a gate 17 to sample the resulting change in potential across the battery caused by the current pulse I, within the period during which the current pulse I is steady. To determine the change in potential across the battery, its potential prior to the current pulse I is stored on a capacitor 22. When the coil 10 is energized, the capacitor 22 is disconnected from the battery and the potentials across the capacitor and the battery are compared by a differential amplifier 20. If their difference # U exceeds a reference potential U s , derived from a regulated voltage source 23 and an impedance matching amplifier 25, a further differential amplifier 26 produces an output signal which is passed via the gate 17 to a control unit 7 to energize a battery charger 6, which remains in operation until the battery voltage U rises above a reference level U c  from a second regulated voltage source 30 and an amplifier 32. The amplifier 32 includes a temperature sensitive resistor 33 immersed in the battery electrolyte in its feedback loop, to compensate for temperature variations in the battery.

Abstract: A method of testing a fluid comprises passing a main flow of a fluid through a conduit 20, inserting into said conduit a cylindrical probe 22 having an inlet opening 24 which faces downstream of the conduit 20 and which communicates with an outlet opening 25 which is disposed in an end surface 26 of the probe, the said end surface 26 being disposed within and spaced from the wall of the conduit 20. The said main flow, in passing through the conduit 20, causes a sampling flow of the fluid to be drawn from the conduit 20, and to be passed through the probe 22 from the inlet opening 24 to the outlet opening 25, and so back to the conduit 20. Testing is effected of said sampling flow. The method reduces the amount of dirt in the sampling flow. Flow, density, temperature, pH, a chemical or physical property may be measured. <IMAGE>
