Title: Anti-theft device for alerting central control - includes relay system with push- button operated re-setting circuit and has identification device
IPC: G08B25/10
Filed: 1974-11-13
Abstract: The anti-theft device is used to transmit radio signals to a fixed on mobile central control, in the case of a break-in, with the device being identified to the control. The device employs a relay (R2) which is normally in an inactive position, but which is tripped into the active alarm position by the opening of one or more series relay contacts (C1--C6). The re-setting circuit for the relay (R2) is operated by a manual push-button (P) with a timing circuit (T1) maintaining the re-setting current for a given period after the release of the push-button (P). A second timing circuit (T2) delays the alarm release for a given period after the relay (R2) operates.

Title: Removal of olefins and dienes from aromatics - by acid catalysed alkylation of aromatics in situ
Inventor: MARCILLY CHRISTIAN
IPC: C10G29/20
Filed: 1974-12-27
Abstract: The olefin and diene content of aromatics-rich fractions is reduced by subjecting the olefins and dienes to an acid-catalysed vapour- or liq. -phase alkylation reaction with a portion of the aromatics. The process reduces the acid wash colour values of the aromatics fractions to =1 without causing a significant decrease in benzene content (since the polyalkylbenzenes are preferentially.

Title: Automatic cleaning of installations for analysing gases - partic. useful in analysing dust-laden furnace gases
Inventor: HERRMANN PIERRE
IPC: G01N1/22
Filed: 1975-01-23
Abstract: Appts. for automatically cleaning a gas sampling probe incorporates a gas container, a source of compressed gas three electrically operated valves and a control system. The container is connected to the suction pipe leading from the sampling probe to the analyser, between the probe and the analyser. The control system brings about cyclical opening and closing of the valves. The cycle brings the press. in the container to the press. of the compressed gas source, isolates the analyser from the probe, produces a shock wave by opening the container suddenly and then re-establishes the normal suction circuit. An ejector is connected to the source of compressed gas and by fourth and fifth valves to the probe and to the container so as to purge them before re-establishing the normal suction. A sixth valve in the line between the compressed air source and the ejector is closed during the increase in press. of the container and the production of the shock wave. Used partic. of installations in which gas contg. large quantities of dust are analysed e.g. gas from furnaces, cement kilns, where water condensed from the gas being analysed or condensation of some vapours in the solid phase can block the sampling probe. The process is automatic abd avoids the shutting down and removal of some parts of the appts. to obtain access to the sampling circuit for cleaning, necessary in existing installations.

Title: Phase shift calculator for two signals - computes phase shifts of carrier and modulating signals
IPC: G01R25/08
Filed: 1975-01-28
Abstract: Measurement of the phase difference between a signal and the same signal after being phase shifted is effected by sampling and then comparing the signals. A generator output (10) is modulated (12) by a lower frequency and is introduced into a phase shift network (14) to enable physical quantities to be measured. The output is detected (16, 18) to select the carrier and modulating signals. The signals are shaped (T1, T3, T2, T4) for calculation (20, 22) of phase shifts. The phase shift of the carrier (F) and that of the modulating signal (f) are then passed into a computing circuit (30) where values of the physical quantity are calculated by a sampling process using a high frequency clock (312). The actual phase shift between the two carrier waves is contained in an output memory (313).

Filed: 1975-01-30
Abstract: The stimulator unit is for objective electro-encephalographic audiometry, and has a programmable electric current generator for several different and selectable frequencies, the output of which is received by a slow opening and shutting gate. A programmable attenuator receives the gate output, its degree of attenuation of the latter being also selectable. The attenuated signal is directed by a diverter to one or the other or both of two outlets, and a two-way sonic amplifier transmits these to earphones fitted to the patient. All the components can be controllable to any desired programme.

IPC: E04B2/70
Filed: 1975-08-13
Abstract: Two wall parts (2 and 3) are connected to a post (1). Individual structural elements (18, 19) of said wall parts have, at least at one end, two tongues (22) which are separated from each other. These are located on either side of a rib (23) of the post (1). The height of the tongues (22) corresponds approximately to half the height of the elements (18) in order that there can be situated, between two tongues of one wall part (2), in each case one tongue of the other wall part (3) or of a joint part (4 and 5) used for decorative purposes. The structure permits the outer side of a building to have the appearance of a log cabin with so-called crossover joints, there being the advantage, nevertheless, of a conventional, high-quality heat insulation in the walls.

Patent FR-2347816-A1 (FR)
IPC: H02H7/00
Filed: 1976-10-20
Abstract: The DC supply apparatus which, in particular, supplies an inductive load has a line-commutated fully-controlled thyristor bridge and an inductor (3) in the DC circuit. In order to be able to switch off the load current very quickly as a function of one criterion, an additional thyristor (8) is provided, which is connected in parallel with the load (4) and takes over the load current if a load-dependant triggering signal occurs. This triggering signal at the same time causes the thyristor bridge (1) to change over into the invertor mode. As a result of this arrangement, the load is immediately short-circuited and the inductive energy in the DC circuit is supplied back into the AC power supply. The apparatus can be used in particular for supplying power to apparatuses for surface heat-treatment with the aid of a glow discharge, since, in this case, operations are always carried out slightly below the arc discharge.

Title: Laser beam power distribution modification - involves array of little mirrors reflecting excess light from centre of beam
Inventor: BELVAUX YVES
IPC: H01S3/00
Filed: 1977-02-18
Abstract: A grating or mash (3) is used to effect a redistribution of the relative intensity in a beam of light produced by a power laser (1). The light beam leaving the laser may have a Gaussian distribution and excess light is removed from the centre of the beam to give a flat distribution. The mash (3) consists of an array of mirrors on a transparent glass sheet. Light passes through the transparent areas to the next stage of the appts. (2) and excess light is reflected, (8). The proportion of mirror to transparent areas is higher at the centre than at the edges.

Title: Liq. spray gas washing installation with variable capacity - has venturis aiding contact of gas with liq. and hydraulic sealing arrangements for selected venturis
Inventor: ALLOYER GUY ALEXIS ALFRED
IPC: B01D47/06
Filed: 1977-03-01
Abstract: Gas passing through the installation contacts a curtain of sprayed liq. An assembly of venturis accelerates the gas through the liq. to improve sepn. of solid particles. One or more of the venturis can be hydraulically sealed to maintain gas speed when the gas flow through the installation decreases. The hydraulic seals are pref. achieved by arranging the lower ends of the venturis at different levels in a vertical enclosure with a controllable overflow just above each level. Alternatively the venturis are at the same level and some are sepd. by partitions enabling hydraulic sealing of these from the gas flow. By use of simple liq. level control, closure of some of the venturis can be achieved without complicated mechanical seals.

Title: Instantaneous mean speed display for vehicle - has counter which processes signals from sensor to produce output representing distance from datum point
IPC: G01P11/00
Filed: 1977-05-03
Abstract: A magnetic sensor (26), palced on the vehicle's speedometer, feeds impulses to a circuit (12) which converts them to logic level pulses and feeds them to a counter (34) in which one impulse represents, say, 10 metres. The sequence control circuit (50) generates a clock function e.g. every 36 seconds, which is fed to a second counter (24), an impulse generator (30), which outputs the impulses contained in counter (34), a programmable frequency divider (14), and a digital display (22). The divider thus gives unit distance in unit time, giving a stored velocity, and thus mean speed over a given distance.
