Title: Balancing for gas turbine compressor rotors - uses blade fixing grooves to secure balance weights before wiring in position
Inventor: HALLINGER CLAUDE CHRISTIAN
IPC: G01M1/32
Filed: 1976-07-16
Abstract: The disc (26) forming part of the compressor rotor (20) of a gas turbine has an axial groove of trapezoidal cross-section. The compressor blade (11) has a root (15) with a foot (14) of trapezoidal cross-section to match the groove (22) in the disc. When the blade (11) is fitted in the groove, the blade platform (13) abuts against the raised rim (24) of the disc (26). A balance weight (31) of the required mass and of matching cross-section is inserted into the groove (22) from the rim side of the disc (26) so that the tail portion (32) fits underneath the rim (24). The balance weight (24) is then secured by locking wire (40) which fits in semi-circular grooves in the rim and in the weight.

Patent FR-2323525-A1 (FR)
IPC: B29C65/10
Filed: 1976-09-09
Abstract: A machine for transforming heat shrinkable thermoplastic material into sealed and liquid-filled containers in which the material in strip form is cut off to a suitable length then heated and transformed into a tube-shaped shell blank on a mandrel with an overlapped longitudinal heat-sealed seam. The shell is then displaced in relation to the mandrel so that its bottom end extends beyond the end of the mandrel, a base blank cut from another strip is then inserted into the end of the shell to rest against the mandrel end, and the shell and inserted base are then heated causing the shell to shrink accurately to the shape of the mandrel and the bottom edge zone of the heated shell to be folded in against the end of the mandrel and the edge of the base. The joined edge zones of the shell and base are then pressed together and heat sealed. The container is then passed to a filling machine where it is filled and closed by a lid.

Title: Toilet seat with foam padding - has reinforcement portions with encased foam cores and weight distributing system
IPC: A47K13/02
Filed: 1976-09-17
Abstract: The resilient synthetic resin toilet seat comprises a resilient premoulded reinforcement member having a foamed inner core which is enclosed in a non-foamed skin. A padded member is also provided which also has a foamed inner core in a tough yet resilient skin and protrudes in one piece from the upper and side faces of the reinforcement. The part of the skin of the padded member which lies above the skin part on the upper and side faces of the reinforcement member is one piece with the skin on the said upper and side faces whilst other parts of the padded member skin together with the other parts of the reinforcement skin form a one-piece full length outer skin for the seat. The outer peripheral surface of the seat is such that when stressed the cross-sectional area of the seat flattens out to distribute the load.

Title: Index pad selector knob and release catch - are both operated against springs for selection and to open cover
IPC: B42F17/34
Filed: 1976-10-08
Abstract: A table top index has a base (1) carrying a stack of pages (2) and a hinged cover (3) carrying another stack of index pages (4) which then rest on the lower stages when closed. The cover (3) has a selector knob (10) which can be slid along an opening alongside the upper stack (4) so that a hook (7) suspended below can engage a selected page in that stack. Thus when the cover is opened, selected pages are raised with it, and the remainder remain unopened below. An arm (8) carrying the hook has protuberances (14) which can be freed from locating holes (15) in the cover when the knob (10) is pressed down against a spring (12). The cover is released when a second knob (18) is swung back against the force of a leaf spring (21) housed in the base (1). A nose (16) at the top is then disengaged from a lounge on the cover.
Patent FR-2371505-A1 (FR)
Title: Synthesis gas from carbon and superheated steam - in atmos. free of oxygen and using the superheated steam as sole heat supply
IPC: C10J3/14
Filed: 1976-11-18
Abstract: Superheated steam is esp. produced by contacting water with a hot heat-transfer medium. The amt. of steam is pref. 2-10 (4-7) times the stoichiometric amt. needed for complete reaction. Pollutant gases are not found in the reaction prod. The ratio of H2:CO in the prod. can be regulated by controlling the temp. and amt. of steam used. No soort or char forms in the reactor. Any S in the C reacts with steam to give H2S, for conversion to H2 and S. Condensn. of excess unreacted steam removese flyash from the prod. gas. Solid waste fuels can supply is no 30% of the energy requirements of the process. The H2 in the prod. is satd. with water vapour and does not cause embrittlement of the steel appts. The synthesis gas can be used as a fuel, for conversion to CH4 (at molar ratio H2:CP = 3:1), to CH3OH (at molar ratio H2:CO = 2:1), or to NH3, N2H4 or liq. fuels, by hydrogenation, (at molar ratio H2:CO of 9:1).

Title: Tuner for FM car receiver - has AFC system and device for automatic gating of interference pulses
IPC: H03J7/02
Filed: 1976-11-26
Abstract: The FM wave system, especially for a car receiver, has a demodulator which delivers voltages (+UR, -UR) appearing on both sides of its demodulator characteristic (K) zero crossing, to a first threshold value dependant electronic switching stage (8), as its control voltages. This switching stage (8) is connected to the AFC system and to the device for automatic gating or interference pulses. When control voltages (+UR, -UR) exceed a specified threshold, they make inoperative the AFC system and the device for automatic interference pulse gating.
Patent FR-2332539-A1 (FR)
Title: Frequency and duration measurement of non-coherent wave packets - using doppler techniques and electronic processing circuits for test criteria for next duration period
IPC: G01S13/58
Filed: 1976-11-22
Abstract: The measuring method is for the frequency and duration of non-coherent wave packets, pref. using Doppler speed measurement devices. The duration of single periods is determined and reciprocals formed to avoid errors caused by overlaping wave packets and accelerating targets. In zero-crossing detection systems overlapping wave resultants may not fall below the threshold level and may produce phase related timing errors. Accelerating targets producing increasing frequency packets result in average frequency indications. A system of duration counter, comparison logic, mean value circuit, and stores is used to generate test criteria for the next duration period to be measured from those previously measured. The output signal is generated by the reciprocal circuit and corresponds to the Dopper frequency.
Patent FR-2344002-A1 (FR)
Title: Reading device for linear or angular scales - has division marks omitted and figures are presented in window of twice size of figures
IPC: G01D13/10
Filed: 1977-02-22
Abstract: An optical reading device is for linear or angular scales in which the result is displayed in figures in a window without the use of scale division markings. The positioning of the figures on the scale and their size in relation to the window opening present the result in unambiguous form without the need for division marks. Reading is simplified, and also the production of the scales, which need have only the printed figures. To permit extrapolation between two values, the window opening (3, 4) may be twice as high as the figure size, with a central reading frame of the same size as the figures.

Title: Fire protection system for IC engine - has hydraulically controlled shutter to shut off engine air supply
IPC: F02D17/04
Filed: 1977-08-02
Abstract: A fire protection system for an engine consists of a shutter (1) which can shut off the air supply. It is normally held open by a bolt (5) engaging a catch (4). The bolt (5) is supported by a hydraulic cylinder (6) supplied with pressure from a pump (8). In the event of a dangerous rise in temp., a thermal sensing device is used to transmit a signal to an electronic circuit which cuts off power to the solenoid valve (12). This, in turn, shuts off oil pressure of the cylinder (6), releasing the bolt (5) and so shutting off the air supply.
