Title: Heat engine parameter curve tracer - has X-Y plotter connected to power and specific fuel consumption calculators
IPC: G01L3/24
Filed: 1974-11-28
Abstract: The heat engine monitoring system takes measurements from the engine under test, calculates performance parameters and automatically draws curves of these parameters. Electrical signals from a torque meter and a speed meter are fed into a calculator which passes an electrical signal level corresponding to the engine power to an X-Y plotter. Signals from a fuel consumption gauge and the 'power' calculator are combined by a second calculator to provide a signal corresponding to the specific fuel consumption, which is the second input to the X-Y plotter. A chart recorder records the fuel consumption on one track and the specific fuel consumption on the second track.

Title: Buried constant pressure drinking water reservoir - has pressurizing-gas exchanging heat with water in external condenser-evaporator
IPC: E03B11/14
Filed: 1974-12-16

Title: DC controlled safety relay supplying AC load - has input synchronised two transistor photocoupled amplifier supplying current to railway signals
Inventor: SERINDAT HENRI
IPC: H02M5/458
Filed: 1975-04-16
Abstract: The relay circuit is used to control an ac supply to a load, such as railway line signals where the control to the circuit is dc level. The design is intended to prevent the generation of harmonics and their consequent interference effects and to provide an alternative arrangement to magnetic amplifier. The relay circuit is based on two transistors, pref. optically coupled, whose bases are supplied alternately by the control dc level. The input ac is fed in via a transformer and rectifier circuit and supplies the two NPN transistor amplifier. Both transistors work in synchronism with the input supply frequency. The collectors feed an output transformer in push-pull, the transformer centre tap being fed from the input rectifiers.

Title: Column mounted vehicle lifting arm - has pivoting locking latch bearing against fixed surface to jam arm in position
IPC: B66F7/02
Filed: 1976-02-27
Abstract: The vehicle lifting arms are mounted on two or more columns, and slew on vertical axes on trucks. The arms travel up and down the columns between one position, in which they can be locked, under the vehicle, and a rest position folded against the column. Each arm (5) has a locking catch (23) pivoting at one end on an axis (22) parallel to that of the arm, while its free end is flush with a stationary surface (9) on the truck. There is a friction component between the catch and the surface, so that any angular movement of the arm causes angular movement of the catch. The free end of the latter bears then against the fixed surface so as to jam the arm in position.

Title: Nuclear reactor with molten salt combustible - has vacuum chamber for safe extraction of gaseous fission prods.
Inventor: VENTRE EDMON
IPC: G21C19/307
Filed: 1976-03-18
Abstract: Gaseous fission prods. are extracted from the combustible of a molten combustible salt nuclear reactor. In such a reactor, the combustible, generally Pu fluoride or U fluoride or a mixt. of fluorides of U or Th, dissolved in fluorides of Li-7 and of Be, is used also as heat transfer fluid in a prim. circuit. The circuit includes the reactor core, a pump and an exchanger in which heat is transferred to another molten salt, which exchanges its heat in turn, in a steam generator. Fission reactions produce radioactive gases, e.g. tritium and Xe 135, which must be removed. According to the invention, a reduced press. is established in the upper prt of a chamber fitted in the primary circuit so as to be partly filled with the combustible salt. The reduced press. causes degassing of the combustible. The process is more effective than existing processes, in which the gases are usually extracted by contacting the combustible with helium in the body of the pump, and the helium is purged. In those processes, the extn. is therefore carried out at a point in the prim. circuit where the salt is at the max. press, and the solubility of the gas is greater.

Inventor: ROJON ALAIN
IPC: G01K1/14
Filed: 1977-02-21
Abstract: Appts. for monitoring the temp. inside an industrial furnace, uses a calorimetric probe ending in a plug (a) contg. a thermocouple. The probe is located on a mounting so it can be moved through a hole into the furnace, and also be retracted out of the furnace. The probe is also fitted with a hammer disk (b) which can be driven against an anvil to impose mechanical shock. The probe is pref. longer than the hole in the furnace wall, disk (b) being located on the probe outside the furnace, whereas the anvil is located on the furnace casing. One pref. method of moving the probe uses a double-acting compressed-air cylinder which can also be rapidly actuated to provide the mechanical shock. The mechanical shock is employed to break dross etc. off plug (a). The dross deposits on plug (a) during the operation of the furnace, and prevents accurate temp. measurement.

Title: Device for holding textile piece during cutting - has table through which needles are selectively projected to hold piece
IPC: A41H15/00
Filed: 1977-03-28
Abstract: Support device for holding a textile material (e.g. a knitted fabric) whilst it is cut into panels includes a table having apertures through which needles project. The needles are carried on supports beneath the table. The supports are movable towards and away from the table by e.g. a pneumatic ram.
