Title: Mechanical milking teat - has central part coner seals and suction tube
IPC: A01J5/04
Filed: 1974-10-22
Abstract: The device can be used for milking machines in which the milk flows directly, without handling, into a storage tank and maintains a constant vacuum in the unit, and therefore in the teat cups during milking. It ensures separation of vacuum and milk in the unit to avoid contamination of the milk in the milk tubes. It automatically lifts the cups, facilitating the application of the machine, and automatically starts and stops the milk pump. During milking, all or part of the milk is retained and emptied after milking. case of goates or sheep.

Title: Wind power collection machine - has rotor with vertical axis and blades with hinged flaps
IPC: F03D3/06
Filed: 1975-02-12
Abstract: A wind power collection machine has a central structure which supports a vertical shaft which carries a rotor having arms each consisting of two parallel members mounted one above the other. The parallel members are joined by vertical members carrying hinges (5) supporting flaps (6) which are prevented from swinging outwards beyond an angle of 90 deg. by cords (7). When the rotor rotates the flaps (6) are folded across the arms, and so present large areas to the wind, or are on edge on to the wind with minimum air resistance.

Title: Tungsten inert gas welding copper to stainless steel - to form vacuum tight joints suitable for helium cryostats
Inventor: MAUNEAU ARSENE
IPC: B23K9/23
Filed: 1975-02-28
Abstract: Process for heterogeneous welding between a copper part and a stainless steel part, uses an electric arc in inert gas. The novelty is the use of a sandwich formed by clamping a Cu plate between two stainless steel plates, the edges of the three plates being on the same level and the arc being directed onto the edge of the sandwich. The thickness of the Cu plate is pref. twice that of each of the steel plates and the edges of the plates should be sharp and without chamfer. For butt welding two tubes, both are pref. provided with a flange, and a stainless steel washer placed next to the flange on the Cu tube to form a sandwich, the tubes being rotated during welding. Process is used e.g. in helium cryostats where the welds have survived numerous thermal cycles between 4 degrees K and 620 degrees K., maintaining a vacuum of 10-9 torr with no leakage of He.

Title: Tyre for aircraft landing wheel - has triangular projections on sidewalls to allow slipstream to rotate wheel before landing
Inventor: THEAULT YVES
IPC: B64C25/40
Filed: 1975-03-13
Abstract: The tyre (11) for an aircraft landing wheel has eight triangular projections (6) equally spaced around the sidewall. These projections (6) are so aligned that the base (7) of the triangle lies on a radius of the wheel and the vertex points in the direction of rotation. When the undercarriage is lowered into the slipstream the air impinges on the projections (6). The force resultants act in the direction of ground rotation of the wheel, which is therefore set in motion. When touch-down occurs, there is only a small relative velocity between wheel and ground. This results in considerably reduced tyre wear.

Title: Hydro cracking of feeds contg. nitrogen - with prior hydro denitrification and high ppressure prefactionation of effluent
Inventor: RETORET JEAN-PIERRE
IPC: C10G47/00
Filed: 1975-05-21
Abstract: Petroleum hydrocarbon feeds contaminated with N cpds. are hydrocracked by (a) contacting the feed with H2 in the presence of a hydrodesulphurisation, hydrodenitrification or hydrocracking catalyst in a first reactor at 300-550 degrees C (pref. 300-470 degrees C) and 15-250) atm; (b) passing the effluent to a 1st separator at the same pressure and a temp. of 200-300 degrees C (pref. 250-290 degrees C) to obtain an NH3-redn. rich vapour fraction and a liq. effluent contg. 50 ppm NH3; (c) mixing the liq. effluent with at least part of the bottom product from a subsequent prefractionator; (d) passing the mixt. to a 2nd reactor, where it is treated at 300-550 degrees C (pref. 300-440 degrees C) and 15-250 (pref. 50-250) atm; (e) mixing the effluent from the 2nd reactor with the vapour fraction from the 1st reactor; (f) passing the mixt. to a prefractionator at the same press. as in the 2nd reactor, and stripping it with a gas (pref. H2) to obtain a vapour overhead (H2 + products) and a heavy bottom product (heavy products + unconverted feed); (g) recycling at least part of the bottoms to step (c); and (h) cooling the vapour overhead, separating an H2-rich gas, and fractionating the liq. phase to isolate the required products. Since the NH3 formed in the 1st reactor by-passes the 2nd reactor, the latter can be operated with a conventional NH3-sensitive hydrocracking catalyst. The heavy bottom product from the prefractionator is recycled at the same pressure as that in the 2nd reactor, thus reducing energy consumption.

Title: Light alloy piston for high speed engines - has bimetallic insert within piston set out near gudgeon pin
Inventor: SCHEUFLER ROLAND
IPC: F02F3/06
Filed: 1975-08-20
Abstract: The piston for high speed high output internal combustion engines, has a continuous cylindrical wall without vertical slots in it. On the inside of the cylindrical piston wall are bimetallic strips which are cast onto the light alloy wall and adjust the deflection of the cylindrical wall under the influence of temperature to maintain a seal between the piston wall and the cylinder. These strips are on the inside of the light alloy piston wall and set outwards into the wall at the bearing regions continuing within the thickness of the wall. They have similar outward strips set into the thickness of the wall round the gudgeon pin bearing surfaces. This improves the temperature compensating effect of the bimetallic strips.

Title: Guiding girdle for continuously cast ingot - has bearing loading mechanisms pivoting away for dismantling
Inventor: PIETRYKA JOSEPH
IPC: B22D11/128
Filed: 1975-09-12
Abstract: A girdle guide for an ingot being cast continuously consists of a series of pairs of rollers placed side by side. Each roller is supported in bearings which can be displaced in a fixed frame transversely to the direction of flow; the rollers of each pair being maintained at a pitch corresp. to the thickness of the ingot by wedges between the bearings. Each bearing on one roller of each pair is applied against a bearing of the other roller of the pair, at a predetermined determined and adjustable pressure, by a loading mechanism. Each of these mechanisms includes a precompressed spring, and is assembled so that it can be pivoted completely out of the way, on a fixed axis, whilst the precompression on the spring is maintained. The guide is without the complicated conventional hydraulic equipment and thus can be dismantled quickly and without difficulty, esp. when replacements of rollers is called for.
