Title: Catalyst assembly for exhaust gas treatment - with axial and radial elastic retaining elements
IPC: F01N3/28
Filed: 1974-10-04
Abstract: Appts. for the treatment of exhaust gases from motor vehicles, comprises (a) a tubular envelope having plugs at each end provided with exhaust gas inlet and outlet apertures respectively, (b) a unitary ceramic catalytic body within, but separated by a peripheral space from, and of the same cross sectional shape as, the tubular envelope, provided with a series of flow paths between the exhaust gas inlet and outlet faces which communicate with the inlet and outlet of the end plugs respectively, (c) an elastic, inorganic, refractory fibrous mass in the peripheral space, applied uniformly and elastically on the envelope and catalyst body, and (d) >=1 elastic support member bridging and space between corresponding faces of the catalyst body and end plug, and applied elastically on these faces while still permitting the exhaust gases to enter and leave the catalyst body, generally in such a way that the refractory fibres retains and insulates the catalyst body within the envelope and offers a certain resistance to flow of the exhaust gases through the peripheral space, while the end support members retain the catalyst body elastically and axially within the envelope. Prevents abrasive and shock damage to the ceramic catalyst body due to movement within the envelope arising from differential expansion and shocks due to vibration etc., during the motion of the vehicle.

Title: Lowering or raising mechanism for venetial blind - has limited torque friction coupling between drive and driven shafts
IPC: E06B9/322
Filed: 1974-10-23
Abstract: The friction coupling between drive (1) and driven shafts (7) prevents blind damage by continued driven shaft rotation at the end of the raising or lowering runs. The mechanism embodies a spool driving a traction belt connecting to the lower blade of the blind, the spool being rotated by the driven shaft (7). The drive shaft (1) drives a sleeve (4) through bevel gears (2, 3), the sleeve (4) containing a flanged bush fitting on the end of the driven shaft (7). The friction coupling is effected by two pairs of dished washers (10, 11, 12, 13) between the flange (9) and the sleeve (4) and a disc (14) attached to the sleeve. The friction coupling is ineffective above a set resistance to driven shaft rotation.
Patent FR-2293962-A1 (FR)
Title: Filter for removing dust from industrial gases - has filter bed of scrap metal grains on a support grid
IPC: B01D46/30
Filed: 1974-12-11
Abstract: A gas filter comprises a housing which is split into inlet and outlet parts by a horizontal filter bed made up of ferrous, non-ferrous or alloyed metal grains held on a support grid, the circulation of gas through the filter being ensured by a fan at the outlet. The filter bed is cleaned by a counter-current blast of air which can be done by distributing a continuous blast over a small area of the bed from at least one ramp. moving parallel to the bed or by nozzles blasting air against the bed or by vibrating the bed support whilst passing regenerating gas. Filters are normally used on an installation in parallel so that some can be being regenerated whilst others are operating. Gas to be filtered can be passed from bottom to top of the filter, with the inlet and outlet ducting to a series of filters being arranged so that the fan at the outlet can circulate clean gas countercurrently through some filters to regenerate them, with the gas used for cleaning being recycled to the inlet of the operating filters. Alternatively the dirty gas can be pre-filtered in a cyclone then passed from top to bottom of the filters with the outlet and inlet ducting arranged so that the gas used for regeneration is returned to the cyclone inlet. Used for filtering industrial gases, e.g. gases from cement kilns, blast furnaces, electrometallurgical and chemical products works. Simple and cheap filter which lasts a long time and can handle large volumes at high temps.

Title: I.C. engine for stationary or vehicle use - runs on hydrogen obtained from thermal decomposition of ammonia
IPC: F02B43/10
Filed: 1975-01-28
Abstract: The engine has a cylinder in which combustion takes place and which contains a sparking plug, inlet and exhaust valves and a piston with a linkage producing a mechanical output. A reactor is placed next to the cylinder and is supplied with ammonia which is thermally decomposed within the reactor into its constituent hydrogen and nitrogen. The gases are fed to the cylinder and the hydrogen provides the fuel for the engine. The reactor and the engine exhaust are arranged so that the heat of the exhaust provides the heat to decompose the ammonia. The exhaust pipe can pass through the reactor or surround it or the heat exchange can be effected by a heat pump.

Title: Sulphur dioxide removal from exhaust gases
IPC: B01D53/02
Filed: 1975-10-23
Abstract: SO2 is removed from waste gases by passage through a solid bed of uniform pieces in the form of saddle shapes or Rasching rings with pore space of >=50% prepd. from a porous carrier, pref. alumina carrying an active substance for the removal of SO2, pref. CuO mainly on the surface of the carrier. The saddles or rings are prepd. by steeping the hydrophilic carrier in a polar org. liquid pentanol-1 in excess of the total pore vol. then removing the pieces and without further drying impregnating with a soln. of a cpd. convertible to the active material. The penetration of the cpd. in to the pieces is controlled by the time impregnation to restrict it mainly to the surface. The impregnated pieces are then dried and the active material produced e.g. CuO by calcining of impregnated Cu(NO3)2. Passage of the hot waste gas through a bed of the pieces removes the SO2 and the bed can be regenerated by passage of a mixture of steam and H2

Patent FR-2316565-A1 (FR)
Title: Water cooler for power stations - having vertical plates alternately irrigated with water and cooled by air
IPC: F28C3/06
Filed: 1976-06-30
Abstract: Heat exchanger for exchange between a liquid and a gas has a number of vertical plates. The exchanger operates in two modes (a) cooling the plates with the gas, (b) cooling liquid flowing over them by warming them back up again. This is organised on a cycle and provision is made during this that the plates are shielded from gas flow for a short period after the irrigation stops. This is done by rotating liquid distributors over radially extending vertical plates. Below the plates are rotating collector trays mounted approx in line with the distributors. However these serve to mask the plates being irrigated from the gas flow and are extended over more plates than those actually being irrigated on the trailing side (i.e. opposite side to rotation direction). This masks these plates to allow drainage before gas flow resumes. Increasingly cooling towers are becoming unacceptable because of water contamination by the atmosphere and excessive water loss. Air coolers are combersome to design suitable for extremes of summer and winter conditions. The cooler described combines the advantages of indirect air cooling and direct cooling without the above mentioned problems associated with them.

Title: Motorcycle anti-theft device - has horn connected to shock detector by logic circuitry controlled by condition of ignition circuit
IPC: B62H5/20
Filed: 1976-10-05
Abstract: A motor-cycle anti-theft device comprises a horn connected to a shock detector by means of logic circuitry which prevents the actuation of the horn by the detector while the ignition circuit is closed, and which makes the horn responsive to the detector when the ignition circuit is opened but only after a predetermined time.

Title: Pipe laying system using mud filled trench - uses grout for connections between pipe sections after immersion, before mud hardens
IPC: E03F3/06
Filed: 1977-01-26
Abstract: The pipe laying system includes forming a trench which is then filled with mud to prevent the sides from caving in, then after the pipes have been laid, the mud hardens to protect the pipes. Before the mud has hardened, the pipe sections are lowered into it, and the connections made while buried. The ends can be blocked before immersion, and removed afterwards, assisted by the presence of grout, which is removed after hardening. The pipes can be loaded with water which opposes the grout. The pipe sections can be connected directly or by using auxiliary connectors after the grout has hardened. The blocking members can be membranes attached by adhesive to the pipe ends.
