Title: Catalyst for reducing nitrogen oxides with ammonia - based on iron-chromium oxides, contains aluminium sulphate
IPC: B01J23/86
Filed: 1975-11-25
Abstract: Catalyst contains 0.1-20% Al2(SO4)3, and pref. contains Fe and Cr in 1:0.02-0.04:1 (1:0.03-0.1:1) molar ratio and is used on a claimed support. The claims also cover the prodn. of the catalyst and its use in the redn. process. The catalyst retains its high activity for long periods. has high stability in the presence of S (cpds.) and can be mfd. cheaply and mfd. and used easily. The base is formed by calcining Fe and Cr salts and/or (hydr)oxides at not >500 degrees C, the Al2(SO4)3 being added before or after calcination, recalcination being necessary in the second case. Catalytic redn. is carried out with NH3 and N oxides, in 0.6-1.4 molar ratio at >=150 degrees C.

Title: Tapestry edge securing strip - has holes for wall attachment and spikes for securing tapestry, and it folds over to conceal edge
IPC: B44C7/02
Filed: 1976-02-04
Abstract: The aluminum strip used to support tapestry or similar hanging material, is designed so that it is completely concealed after installation, this being carried out by hand pressure. The strip has a row of rectangular openings along it, so that the strip can be mounted on a surface by using staples which bridge the remaining metal between the openings. Rows of holes are also included where the strip is to be secured by nails instead of staples. Along the bottom edge is punched out a row of spikes. The tapestry is forced over these spikes, along its top edge, then the strip is simply bent outwards and upwards into a U-shaped, calmping the edge of the tapestry between the arms of the U. The bottom edge may be similarly secured.

The sleeve (10) the pressings (14) and the sealing collar (8) can be assembled to form a sealing cartridge before being fitted to the roller.
Patent FR-2310958-A1 (FR)
Title: Catalytic hydrocarbon convertor - with diverging reaction space and graduated corundum spheres filling for reaction zone control
IPC: C10G11/18
Filed: 1976-05-12
Abstract: A reactor for the catalytic conversion of hydrocarbons with an oxygen-contg. gas includes a reaction space which is filled with a catalyst. The reaction space and/or the catalyst filling present a cross-section which is enlarged in the direction of flow. This causes a reaction zone of a conversion, started under normal working conditions at the inlet, always to migrate towards the middle of the reaction space. This can absorb even large fluctuations in the gas demand (when used as a cracked gas generator for the internal combustion engine of a motor vehicle). Backfires are thereby reliably eliminated. The prod. of soot is reduced to a min.

Title: Protection circuit for nodal point in power distribution system - isolates node when fault appears and one coupling transformer saturates
Inventor: CHIFFERT ALAIN
IPC: H02H3/28
Filed: 1976-08-31
Abstract: The protection circuit, for node in a power distribution system, has a first device producing a first logic signal when a fault appears in the node and a second device producing a second logic signal when at lest one of the transformers coupling the power system's lines together is likely to saturate. These two logic signals are applied to a logic circuit that produces an output signal that isolates the node from the rest of the system. The logic produces a first control signal when the first logic signal appears and a second control signal when the first and second logic appear.

Patent FR-2375756-A1 (FR)
IPC: H02P7/28
Filed: 1976-12-22
Abstract: In the case of DC-driven motors in the field of traction, for energy-saving reasons it is desirable to recover electrical energy when the vehicles are braking. In order to ensure both good driving operation and good braking operation, the braking resistor (R), the excitation winding (I) and the rotor winding (M) of a motor are arranged in mutually parallel load branches and are individually controlled by load-branch thyristors (Th1, Th2, Th5). A changeover device (H), which is common to all the load branches, is connected in series for controlling these thyristors and turning them off. This arrangement is particularly suitable for switching the motor over to the following operations phases: motor supply, field weakening of the motor rotor, resistance braking and regeneration braking, regeneration braking taking precedence over resistance braking.
Patent FR-2336287-A1 (FR)
IPC: B61C11/04
Filed: 1976-12-24
Abstract: The rack and pinion monorail has a box-shaped running rail (3), the underside of whose running rail is provided with a toothed rack (4). It has at least one drive wheel set which has running bearing wheels (6) on the upper side of the running rail and at least one toothed drive wheel (8) on the opposite side of the running rail, which toothed drive wheel (8) grips into the toothing of the toothed rack. In order to be able to operate the rack and pinion monorail at a substantially higher speed and to be able to use it in particular for passenger transport, the running rail has, in addition to the toothed rack on the underside of the running rail, additional running faces (11) to which bottom wheels (13) which are provided with rubber tyres (12) are assigned, the bearing wheels having rubber tyres (14) also and being constructed and configured together with the bottom wheels as control wheels for the depth of engagement of the toothed drive wheel. If one of the wheels (6; 13) is constructed as an adhesion drive wheel, either the toothed drive wheel (8) or the adhesion drive wheel (6 or 13) can be activated by appropriate setting of compressed air in these wheels.

Title: Windscreen wiper for moped - has crown wheel on front wheel and two endless screws giving reciprocating action for cable drive
IPC: B60S1/06
Filed: 1977-01-13
Abstract: The windscreen wiper for a moped is driven by a toothed crown wheel which, in turning gives turning motion to two parallel opposed endless screws. The crown wheel is fitted to the front wheel and drives the cables (A) with reciprocating action. The drive is taken to a head on the handlebars which carries the windscreen wiper blade shaft, so causing it to oscillate. A knob control at the rear of the head disengages the drive when wished. The advantages are that it dispenses with the normal need for hand or electrical power to operate.

Title: Revolving drum screen for solids separation - with rolling elements outside drum top centre line to keep perforations clean
IPC: B01D33/11
Filed: 1977-03-18
