Patent FR-2235043-A1 (FR)
Title: Gas turbine marine engine - with hydrodynamic brake to slow propeller shafts before reversing thrust
IPC: B63H23/30
Filed: 1974-06-27
Abstract: The gas turbines are run at optimum speeds and their output shafts are reversed by two epicyclic gears with friction brakes; one brake off and the other on. In order to reverse the thurst without slowing the turbines, and without undue heating of the friction brakes, hydrodynamic brakes are fitted to the output shafts to stop the propeller shaft rotation before the reverse drive is applied. These brakes are pref. disc units operating on a flange of the annular gear elements.

Title: Capacitive based voltage reducer and regulator - derives low voltage from higher voltage source to maintain constant potential at load
IPC: H02M3/10
Filed: 1974-10-18
Abstract: The combined voltage reducer and regulator delivers a relatively low voltage, derived from a higher voltage source, to a load as to maintain a relatively constant voltage at the load. The voltage reducer comprises capacitors, diodes and selectively operated switches which, dependent upon the order of application of timing signals, operate in either one of two different modes to achieve different degrees of voltage reduction. The inherent nature of the capacitors provide a limited degree of voltage regulation. Supplementingthis, in each mode of operation, a voltage regulator or regulating circuit is provided to provide a fine degree of voltage regulation between limits.

Title: Locking system for loading scoops - has auxiliary lock coupled by coupling rod with coupling lever
IPC: A01D87/00
Filed: 1975-03-28
Abstract: The device releases the loaded tool allowing it to pivot and dump the load and subsequently return automatically to the "ready for loading" state. A projecting support holds a mast connected at its upper end by a swinging link to the loader arm. A wheel maintains the assembly at a given height above the ground. A loading scoop is articulated to the projecting support and a tenon projecting from it rear is connected via a link to a coupling rod and thence to a controllable lock. When this is released, the link is released at the same time as a coupling lever under the action of the loading scoop swinging to the empty position. As the scoop swings back, the link lever pivot back and the release is reset.

Title: Drilling probing device using acoustic signal - has demodulator controlling reference signal generator for phase state
IPC: E21B47/18
Filed: 1975-04-07
Abstract: This signal is modulated between two phase states as a function of data bits in numerical code which are a function of data bits in numerical code which are a function of a base condition. A change of phase represents a bit of one character, and the absence of change another, and each bit representation is dissembled during a predetermined binary period. It has a demodulator for the acoustic waves, producting an output signal representing phase and frequency of an acoustic signal. This controls a generator producing a reference signal which has a phase state which is one of those of the output signal. The latter and the reference signal are received by a correlator, and produced a synchronised rectified signal whose polarity represents the phase states of the output signal.

Title: Fuel economising system for road vehicles - has pressure sensitive device in inlet manifold operating solenoid to close throttle butterfly and open air by:pass
IPC: F02N99/00
Filed: 1975-07-03
Abstract: A pressure sensitive device (22) is fitted to the inlet manifold (1). When the vehicle is moving under its own inertia, and the accelerator pedal (8) is therefore not depressed, the depression in the inlet manifold (1) actuates the device (22) which closes the switch (33). Closing the switch (33) energises the solenoid (12). When the solenoid (12) is energised the butterfly valve (5) of the carburettor (2) is closed and a by-pass valve (14) is opened. The by-pass valve passes fuel free air to the engine so that no fuel is used under these conditions. When the accelerator pedal is depressed the solenoid (12) is deenergised and the engine resumes normal running.

Title: Core power density locally measured - by external neutron flux chambers installed inside core
IPC: G21C17/10
Filed: 1976-03-15
Abstract: A nuclear reactor, esp. a pressurised water power reactor comprises a column-shaped core with in-core neutron flux detectors and also neutron flux detection chambers outside the pressure vessel and temp. measurement equipment. Either (a) only in the core centre or (b) at a minimum of 4 peripheral points around the vessel and also in the core centre, there are a number of neutron flux external chambers distributed through the core height. A number of multiple (esp. 4-fold) temp. detectors esp, thermocouples are distributed across the core at top and bottom. These detectors and the flux external chambers are electrically connected to a measuring device to indicate the local power density. Chambers at the centre are pref. surrounded by a protective tube. Neutron flux external chambers are used, instead of neutron detectors, inside the core. The former are much more robust. In addn. with this arrangement, they are replaceable, without shutting down the reactor. The top and bottom distribution of temp. detectors gives a good additional spread of radial and azimuthal readings.
