Title: Removing nitrogen oxides from waste gas in adipic acid mfr - by hot catalytic redn with ammonia
IPC: B01D53/94
Filed: 1976-03-19
Abstract: Process for eliminating nitrogen oxides NOx from residual gases contg. a large amt. of oxygen and/or oxygen cpds. e.g. nitrous oxide, the process being used in a plant mfg. adipic acid. The NOx are reduced by ammonia at high temp. employing as a catalyst a mixt. of an iron oxide and a chromium oxide. The catalyst is pref. distributed throughout several stages and part of the current of ammonia introduced before each stage, and the residual gas is pref. heated to 260-310 degrees C. for removal of the NOx. The residual gases arising in mfg. adipic acid contain up to 10000 ppm. NOx which is removed to avoid environmental pollution when the gases are discharged into the atmos. An economic process which is effective despite the presence of large amts. of O2 and N2O in the gas.

Title: Plastic lined concrete channel for waste water purificn. plant - assembled from prefabricated modular elements with sealed plastic joints
Inventor: HAMEL RAYMOND
IPC: C02F3/02
Filed: 1976-03-24
Abstract: The plant comprises an oxidn. zone in the form of an elongated channel. The oxidn. zone is made up by assembling tubular parallelepiped elements made of concrete. Each element is made with inlet and outlet openings of the same size and shape. The element is internally lined on its base and two sides with a sheet of thermoplastic material which extends through inlet and/or outlet openings to form flaps. To assemble two elements for continuous flow, the outlet of the first element is superimposed against the inlet of the second element, and the flaps of one are seam welded to the lining of the other. An element may be open at both ends for straight through flow, the unlined concrete top pref. having a manhole type aperture. The thermoplastic sheet is pref. secured to the concrete by having protruding studs on one side of the sheet for anchoring in the concrete as the element is cast. Used for constructing channel type oxidn. zones for waste water treatment plants. Modular construction enabling any size and shape of zone to be made up is provided and facilitates very cheap construction of channel type oxidn. zones.

Title: Sensor for detecting reducing gases - in which resistance of a semiconducting oxide varies with concn. of reducing gas
Inventor: OIDO HIKOFUMI
IPC: G01N27/12
Filed: 1976-12-16
Abstract: Sensor for reducing gases, the novelty being the use of a tubular heating element using a multi-turn coil of wire coated by a refractory material to prevent adjacent turns from touching each other. In the middle of the tube is a sensor in which electrical leads are partly embedded, and the sensor does not touch the heating coil, which is designed to heat the sensor by radiation. The refractory material is pref. applied at two locations on each turn of wire, or it may completely cover the coil to form a tube. The coil of wire is pref. made from (a) Pt-Ir; or (b) Fe-Cr-Al alloy. The refractory material pref. consists of an inorganic binder, whereas the sensor is pref. a semiconducting metal oxide with a specific resistance which alters in the presence of a reducing gas. In the pref. mfg. process a conducting laminar frame is used with a straight base and two pairs of projecting parts, one pair being used to support the heating coil, the other pair to support the sensor via its electric leads. Accurate and reliable measurement of the concn. of a reducing gas even when the temp. in the vicinity of the sensor varies, as the heater coil keeps the sensor at a constant temp., necessary for accurate measurement.

Title: Continuously cast iron bars - which are bent after casting and cut to length after bending
Inventor: OGER JACQUES FRANCOIS MARIE
IPC: B22D11/12
Filed: 1977-06-06
Abstract: Bent metallic workpieces are made from continuously cast prod., the profile being bent continuously before being cut to successive lengths. The profile is heted to between 600 and 700 degrees C during bending. Process can be used for spheroidal graphite cast Fe for the construction of tunnel arches.

Title: Radio interference suppression circuit - uses pulses synchronised with car ignition pulses applied to gate blocking signal reception
IPC: H03G3/34
Filed: 1977-11-15
Abstract: The interference suppression circuit is intended for a car radio provided with a controlled gate in its signal path radio provided with a controlled gate in its signal path which blocks the received signal during application of a blanking out pulse. A pulse shaping stage precedes the gate control input. It has an input terminal connected through a wire to the car ignition system, and delivers pulses synchronised with ignition pulses. Thus pulses derived from the ignition system are shaped and used to apply a blanking pulse to the gate in the radio signal path. This suppresses noise signals.

Title: Detection of lightning from thunderstorms - utilises alpha particle generator for measurement of earths electric field
Inventor: PIERSON ALEXANDRE
IPC: G01R29/12
Filed: 1977-12-02
Abstract: Lightning from thunderstorms is dangerous in particular circumstances where explosives are being handled. The presence of a thunderstorm is determined by measurement of the earth's electric field by utilising an alpha-particle generator. A rotating horizontal screen (39) modulates the signal resulting from the earth's electric field. This is sensed by electrodes (7, 9) coupled to a differential input amplifier (59), whose output is filtered (61) to eliminate mains frequency. The output is applied to a capacitance diode (63) whose output is transmitted by cable (64) to a comparator (65) where a reference value is applied from a potentiometer (67). The comparator output is applied to alarm (71) and tert (73) circuits both of which receive signals from a control and sequencing circuit (75). This circuit activates a circuit (81) to provide a test voltage.
