Title: Inward flow dust filter - back flushed with travelling nozzle serving several elements
IPC: B01D46/04
Filed: 1972-10-13
Abstract: A method of back-blowing inward-flow dust filtering elements, e.g. tubes or bags, to clean them, consists of introducing a compressed air pulse through a nozzle situated at the discharge mouth of the tube or bag.

Title: Furfural prodn. from bagasse in static hydrolyser - with steam injected from a distributing ring at base of appts.
IPC: B01J4/00
Filed: 1974-01-03
Abstract: Furfural is prepd. from cane sugar bagasse in static hydrolysers which are cylindrical in the upper portion and conical at the base where steam is introduced through a distributing ring of tubes; these create mixing currents inside the appts. and assure an internal circulation of the bagasse particles. The contact surfaces between the bagasse and the steam are thus being continuously renewed so that the furfural is readily entrained by the steam; this allows the yield to be considerably improved. The static hydrolyser is much more simple than rotary and continuous reactors; it therefore shows greater reliability. The steam injection ring effectively prevents any blockage during the emptying of the plant and evacuation takes place by simple hydraulic flow.

Title: Cooling end of rotary furnace - by circulating molecular salt heat exchange fluid in jacket
IPC: F27B7/38
Filed: 1974-03-28
Abstract: A means for cooling one end of a rotary furnace consists of fitting a jacket of suitable length and putting into it a molten salt heat exchange fluid. The salt does not fill the jacket, so that excessive press. cannot develop. The jacket may have an Archimedean screw in it, to increase circulation of the salt, and may be fitted with fins, across which air may be blown. The heat exchange fluid may be a mixture of sodium and potassium nitrates melting around 150 degrees C. The invention provides a means of cooling the end of a rotary furnace in situations where cooling by direct air blowing over the end is not efficient enough.

Title: Pressed-metal building panels assembled without bolts - by using hollow section capping pieces, making erection quick and easy
Inventor: CHARY JACQUES
IPC: E04C2/40

Title: Injectable antineuritic solutions - made and stored under acid conditions by adjusted to physilogical acidity just before administration
IPC: A61K45/08
Filed: 1974-06-14
Abstract: Injectable solns of antineuritic mixtures, contain vitamins, coenzymes and associations of these. The vitamins and coenzymes are prepd. at pH 2.5-5 and are stabilised by lyophilisation or other means to preserve their chemical structure and activity and, this matl. is converted into an injectable soln. by means of a solvent which is kept separate but supplied in the same package as the active matl, the solvent being a buffered, pyrogenic sterile soln. contg. physiological ions which gives the final soln. og pH of 6-6.4: the soln. being administered within an hour of its prepn. Conventional antineuritic solns are at pH 2.5-5 in order to preserve the activity of the vitamins etc. Such solns cause local irritation because of their acidity. The novel solns. maintain the activity but are free from side effects.

Title: Carpet prodn by planting fibres into resin layer on support web - and cutting fibres with pusher to release fibres from cutter
IPC: D04H11/00
Filed: 1975-02-10
Abstract: A pile carpet is formed by advancing a support web over a support table beneath upper and lower feed clamps which co-operate to engage a row of continuous yarns and move them vertically so that the lower ends of the yarns are embedded in a layer of adhesive resin (e.g. PVC) on the upper face of the support web. A holding clamp positioned beneath the feed clamps then hold the yarns at a position above the lower ends of the yarns whilst a cutter adjacent the holding clamp cuts the yarns to produce pile fibres. The support table is moveable downwardly to allow the pile fibres to be released from the cutter and holding clamping whilst a horizontally moveable pusher bar pushes the upper ends of the pile fibres to ensure that they move under holding clamp as the support web is advanced. Subsequently the web is heated pref. by passage over a roller to cure the resin and fixe the pile fibres in position. Wide pile fabrics can be produced at higher speeds without risk of a badly formed pile.

Title: Reconstituted cellulosic papers for electrical insulation - made by reconsolidating creped paper to at least its original density
IPC: D21H25/00
Filed: 1975-02-10
Abstract: Cellulosic papers made by (a) converting a basic cellulosic material into a malleable state, (b) increasing the mass/unit surface to obtain an intermediate state material, and subsequently (c) increasing the mass/unit volume to a level at least as dense as the original feedstock. The process is used for the conversion of cellulosic materials to paper or card structures esp. suitable for enclosing the windings of oil filled transformers or motors, rated at =500 kVA or for insulating electric cables. The modified structure has enhanced tolerance for local pressure from curved windings without tearing because of an improved combination of elasticity, flexibility and strength.
