Title: Accurate cutting and welding of vertical concentric tubes - esp. for rapid replacement of worn oxygen-lance heads in steel making
IPC: C21C5/46
Filed: 1974-03-12
Abstract: A device for cutting and welding concentric tubes in the vertical position, where the space between the tubes forms a water-cooling jacket. The tubes are held from the top in a jig which permits the inner tube to be raised and lowered over a small range. The bottom ends of the tubes are clamped to a centre plate which is fitted with two arms, rotatable through 360 degrees, each arm being provided with an adjustable tool-mounting to house either an electric-powered cutting disc or a welding gun. By tilting the tool-mounting, and feeding the cutter inwards, the outer tube can be cut at an angle suitable for subsequent welding; the centre plate is then lowered and the inner-tube cut off. The worn portion of the lance can thus be removed and a new end inserted in the centre plate and both tubes welded to the main portion of the lance.

Title: DC to DC converter with isolated output - suitable for aircraft control panel illumination and uses relaxation oscillator which triggers transformer input
Inventor: GAUME ROBERT
IPC: H02H7/12
Filed: 1975-01-24
Abstract: The secondary winding of the transformer(22) supplies an amplifier(25) connected to an isolating transformer(30) whose output is rectified filtered and fed to the output via a current measuring resistance(37).

Title: Grid cooler for cement clinker - with heat exchanger to eliminate use of excess cooling air and improve thermal efficiency
Inventor: GHESTEM GERARD
IPC: F27D9/00
Filed: 1975-02-26
Abstract: Cooler is located at the outlet of a furnace employed to roast minerals. The coller consists of two grids in a closed chamber. The lower grid receives material from the upper grid, and cooling air flows upwards through both grids. The novelty is that an indirect heat exchanger is located between the two grids and is traversed by the air; and a refrigerating fluid flows through the heat exchanger to cool the air before it passes up through the upper grid. The heat exchanger pref. consists of a recuperation boiler, in which water is converted into steam by radiation from the clinker and hot air rising from the lower grid. The material pref. flows through a crusher located between the two grids. Device is esp. used in calcining cement where normally only a part of the cooling air can be used as sec. air in the furnace and a heat loss of 105-115 kcal/kg clinker results, 35-50 kcal/kg of the heat previously lost is recovered.

Title: Hot fluid ducts with clad internal insulation - ceramic pellets between metal liners keep pressure walls cool
IPC: G21C11/08
Filed: 1975-03-13
Abstract: A duct to carry very hot gases or liqs. is lined internally with insulation clad on both sides to protect the pressure walls from heat. A large dia. duct is lined with a layer of insulating matl. located between two liners. This insulating matl. could for example be hollow pebbles of ceramic matl. The insulation is kept in posn. axially by 'Z' shaped baffles between the two liners, which also serve to locate the liners. The clearance between the outer liner and the duct wall must be sufficient to permit the differential expansion. Outside the pressure duct there is a corrugated cover, provided with air cooling and outside this a layer of protective insulation.

Title: Automatic control of milling machine head - has pneumatic transducers on head and workpiece
IPC: B23Q15/18
Filed: 1975-04-10
Abstract: The milling machine slide has two blocks on one side. These move across the faces of similarly spaced air nozzles (8) on the machine frame. A signal is given to a counter (14) when both sets are in alignment. Depending on the dimension set on the counter, a stepping motor (16) moves the head down. This gives the theoretical size for the part being machined. The size is corrected for milling cutter wear by another pneumatic pick-up (11) on the workpiece. This measures (13) the actual size of the part and the difference (12) between both sets of figures is used for correcting the cutting head position.

The bending rolls are mounted in stationary stands and each is fitted with an individual drive moving it in a desired direction. The individual bending roll drives pref. consist of eccentric bushes keyed on the drive shafts, the rolls rotating freely on the bushes; adjustment is pref. provided in a second plane (II) at 90 degrees to (I), the combination providing bending in numerous planes. High speed straightening of large profiles, e.g. bars and pipes, is thus possible.

Title: Concrete reinforced by random distribution - of short steel wires, obtd. by cryogenic crushing of used tyres
IPC: C04B14/48
Filed: 1975-06-13
Abstract: Process for mfg. a reinforced concrete, where the reinforcement consists of short lengths of fine steel wires which are distributed at random in the concrete mixt. The novely is that the short steel wires are obtd. by cropping wires from used rubber tyres contg. a metal support or carcase, after removal of the rubber and fabric. The wires are pref. obtd. by the cryogenic embrittlement of the rubber and its crushing into granules so that the steel wire can be recovered from the tyres. The wire is available at a low price because it is scrap and also due to the rubber residues adhering to the wire; but the adherent residues assist bonding of the wire to the concrete.
Patent FR-2315316-A1 (FR)
Title: Crucible for monocrystal ingot mfr. esp. semiconductors - with separate seed-crystal receptacle connected by channel to main receptacle
Inventor: BESSELERE JEAN-PIERRE
IPC: C30B11/00
Filed: 1975-06-25
Abstract: A crucible for making a monocrystalline ingot by controlled, progressive crystallisation from the liq. phase, is in two sections, joined by a channel at their lower parts. One section serves as the housing in which the crystal seed is placed. The other, main section is the section in which the ingot grows. The sections and the channel have the same width at the base and are of the same height as, or the seed section may be higher than the main section. The seed crystal section is arranged so that the crystal slides in it vertically or at an oblique angle to the vertical. The crystallisation in the main section develops horizontally. Device is esp. for making semi-conductors of e.g. germanium, gallium arsenide, and ternary compounds. Sepn. of the sections allows the temp. of the seed crystal to be fixed precisely, avoiding melting by heat conduction from the main section. The crystallisation front extends over the width of the crucible, so that it is easy to ensure that the solid-liquid isothermal surfaces have the desired curvature, convex towards the liq. phase, to prevent anomalies near the crucible walls. The vol. of the seed crystal can be samall e.g. it can be a thin sheet. The ingot has a uniform section over all its length. The seed crystal section can have different posns. and the angle of inclination can be varied facilitating the final cutting of the ingot by affecting the orientation of the crystallisation planes. The process leads to considerable economies in the use of material, by reducing losses to 7-11%, compared to 20-35% in existing processes.

Diaphragms of desired shape and dimension can be mfd., esp. suitable for electrolysis cells operating with alkali metal chloride solns.
