Title: Catalyst for steam reforming gaseous hydrocarbons - contg. nickel oxide, alumina, magnesia, and calcium and barium oxide
IPC: C01B3/40
Filed: 1974-04-24
Abstract: A catalyst for hydrocarbon conversion comprises 25 wt% NiO, 50 wt% Al2O3, 14 wt% MgO, 10 wt% CaO and 1 wt% BaO. The catalyst can be used for the conversion of gaseous hydrocarbons into gases contg. H2, CO and CO2 by reaction with steam, CO2, or O2, esp. for steam reforming CH4. The presence of BaO (and absence of SiO2) increases the mechanical strength of the catalyst and increases its resistance to thermal shock. Cylindrical pellets of the catalyst (i.d. 7 mm, o.d. 15 mm, length 12 mm) have a rupture strength of 600-900 kg/cm2, an apparent density of 2.3-2.5 g/cm3, a total porosity of 20-30%, a specific surface of 60-90 m2/g, and can be rapidly heated and cooled between 20 and 1000 degrees C twenty times without disintegration.

Title: Pressure control valve for trailer pneumatic brakes - isolates trailer supply when trailer brake line broken, for hold-off brake operation
IPC: B60T15/60
Filed: 1975-04-24
Abstract: The supply line to the trailer pneumatic brakes is protected by a special pressure control valve which is spring loaded and is subjected to the pressures in the two braking systems, i.e. trailer and towing unit. In the event of a leak in the trailer brakes the valve closes so that the trailer brake pressure falls more rapidly than it would if supplied from the towing unit. This enables the automatic hold-off brake to operate rapidly. To increase the brake response, the control valve element can be coupled to a venting valve which vents the line of the trailer brakes. If the trailer is not coupled to the towing unit then the valve operates in any case and is thus prevented from seizing up through non-use and corrosion.

Title: Impact release mechanism for acoustic buoy dropped by parachute - has pin spring biased in sleeve with retainer balls knocked into grooves
Inventor: HAROU CLAUDE
IPC: B64D17/62
Filed: 1975-06-26
Abstract: The release mechanism for an acoustic buoy has a central pin (14) to which the parachute cord is attached. The spring (23) normally keeps the pin (14) in position, but when the parachute is deployed the spring force is overcome. The lower balls (43) are pushed radially outwards into the sleeve groove (41) and the pin slides upwards until the upper balls (42) drop into the upper groove (37) in the pin shaft. The pin then pulls the sleeve (15') upwards until it is held by the lower balls (43) wedged against the upper edge of the groove (41). When the buoy strikes the water the release of tension in the parachute cord allows the spring (23) to push the pin (14) down so that the lower balls fall into the lower groove of the pin, releasing the sleeve (15') so that the parachute is separated from the buoy.

Title: Citral as an insecticide and nematocide - against e.g. diptera, lepidoptera, or phytopathogenic nematodes
IPC: A01N49/00
Filed: 1975-07-22
Abstract: Diptera and lepidoptera are killed by contacting with citral vapour in a concentration of ca 1-20 ppm in the air. The growth of flies is inhibited by contacting their eggs or larvae with a growth-inhibiting amount of citral (citral being added to their growth medium in a conc. of ca 0.4%). Egg-laying by adult female flies is inhibited by contacting the flies with an effective amount of citral (citral being added in an amount of up to ca 0.2% to the medium which causes the response to egg-laying). The intake of food by moth larvae is inhibited by contacting the larvae with 0.03-0.1 ul citral/larva. Mosquito larvae are killed by adding a lethal amount of citral to the water in which they live. Phytopathogenic nematodes are killed by contacting them with ca 0.02% citral in the surrounding soil. Agents for the above contain citral, opt. together with usual carrier matls. or diluents. Citral (a known cpd. used in perfumery and as an intermediate for vitamin A) has been found to have pesticidal props. It has a toxic, repellant or inhibitory effect on insects of the orders Diptera and Lepidoptera and against nematode worms.

Title: Anchorage for a floating platform with fixed mooring - is formed by drag-increasing pipe assemblies of limiting deflection
IPC: B63B21/50
Filed: 1976-06-18
Abstract: The anchorage of an offshore structure floating at a selected position in a body of water, is designed for maximal wave and current conditions. The anchorage is effected by placing a baseplate structure on the under water bed where required, and attaching to it the buoyant structure via parallel legs. Each leg consists of a number of long hollow tubes each of which is under tension and is maintained parallel to the others by spacers positioned at predetermined points along the leg assemblies. The spacers are designed so as to increase the lateral drag on the water and they are positioned so that the maximal deflection of the stand pipes is less than their spacing apart. Prevents the stand pipes from damaging each other and reduces the possibility of damage by fatigue in the stand pipes as a consequence of resonance motion caused by unstable vibration.
