Title: Still partic. for brandy - in which liquor circulates in counter-current with the vapour
IPC: B01D5/00
Filed: 1973-07-11
Abstract: Still, is arranged so that the liq. to be distilled circulates in counter-current with the vapour; it consists of two parts (A, B) with pipes carrying the vapour and te liq. in opposite directions. Part B has two superimposed receptacles traversed by spiral coils; the lower receptacle has a principal coil and two auxiliary coils. the head and the tail prods. are condensed in the latter and are drawn off at at taps; the best alcohol, the principal prod. is drawn off at from the principal coil. The liq. to be distilled fills the lower receptacle; it passes via a connector to the upper recipient where it is progressively heated as it condenses the vapour in the coils. The heated liq. flows through a pipe to the directly fired still. This has an outlet for the exhausted liquor while the still is surmounted by a column of plates. The alcohol is removed from the hot liquor in the form of vapour which passes via a funnel to the pipe and the condensers. The amount of head-rrom required is reduced. A concn. of 70 GL of alcohol can be obtd. from light wines, ciders and distillers wash while the head and tail prods. are eliminated.

Most of the air is recycled to the dryer heater, and that part discharged to atmos. is cleaned by a chemical scrubber, (or e.g a catalytic combustion unit), thus obviating offensive odours around site.
Patent FR-2215511-A1 (FR)
IPC: E01C7/32
Filed: 1974-01-25
Abstract: The device consists of a hot-applied, bituminous carriageway surface (11) of asphalt concrete onto which a wear layer (13) of asphalt can be applied, and a sub-base (1) of concrete or metal, where said sub-base may be the upper part of a bridge slab. If appropriate, a sealing course is disposed therebetween, consisting of a cold coat (3) followed by a glass fibre non-woven fabric layer (4) and a mastic asphalt layer (6). Between the carriageway surface (11) and the sub-base (1) or the sealing course (3-6) there is disposed a 2-3 mm thick ethylene copolymer-containing bituminous sheet (8) which has a thermosetting non-woven fabric (10) on its topside and is adhesively bonded or welded in strips to the sub-base or is welded to the mastic asphalt application (6). Said sheet (8) effects a good sealing, so that the sealing course with the mastic asphalt layer can be entirely or partially dispensed with. A much simplified construction and material saving are thereby achieved.

Title: Nitrogen prodn. from air - air-propane mixture burnt twice over platinum catalyst
IPC: C01B21/04
Filed: 1974-02-13
Abstract: Preheated air at 200-300 degrees C is mixed with 2-5% propane gas and burned in a catalyst chamber, pref. using a platinum catalyst. The ensuing gases are then burned in a second catalyst chamber also supplied with propane. By measuring the O2 content of the processed gas, and using suitable control equipment, the amount of propane supplied to the two chambers can be regulated. The resultant mixture of N2 water vapour and CO2 is then passed through a condenser to extract the water and the CO2 is removed by a separator of the molecular-sieve variety which can be regenerated by hot air. A relatively small installation produces nitrogen of 98 to 99.5% purity which can immediately be used as an inert gas, e.g. for the storage of explosive gas. As the equipment works far from the inflammability limit, it can be used safely on land or at sea.

Title: Clamping arrgmt. for elongated workpieces - uses hydraulic cylinder for clamping through angled plunger during hole boring
IPC: B21D43/00
Filed: 1974-11-28
Abstract: The workpiece is supported on a rod which can move to and fro in a guide tube and is supported at its end under the workpiece by a roller. A pin mounted in the rod protrudes through the guide tube through a groove. The workpiece support rod is moved to and fro by a second hydraulic cylinder. Due to the pin in the screw shaped groove, the rod will at the same time be rotated over an angle of 90 deg. Two protrusions are mounted at the end of the support rod. The end protrusion provides an end stop for the workpiece when the first hydraulic cylinder pushes the plunger against the workpiece.

Title: Butterfly valve with sealing ring in valve plate - has ring flange clamped between faces in valve plate
Inventor: SANTY JEAN MAURICE ANDRE
IPC: F16K1/46
Filed: 1974-12-05
Abstract: The sealing ring (15a) has a circular outer section (17a) joined by a neck (18a) to a thicker inner section (16a). The thicker inner section is clamped in the groove formed between the valve plate (5a) and the clamping ring (6a). The clamping ring groove extends radially outwards into a groove of trapezoidal section. When the sealing ring (15a) is exposed to pressure the outer portion (17a) is pressed into the trapezoidal groove without the material of the ring being extruded through the gap between the valve plate and the valve bore. This allows the use of a sealing ring with sufficient flexibility to accommodate any eccentricity between valve plate and bore.
