Title: Starch contg. rayon fibres for textile fabrics - obtd. by extruding aq. alkaline starch and viscose and regenerating cellulose
IPC: C08L1/06
Filed: 1979-02-15
Abstract: Starch-contg. rayon fibres are prepd. by forming a slurry of starch granules in an aq. medium, adding NaOH to form an aq. alkaline starch soln., blending the soln. with viscose, extruding the viscose in fibre form and regenerating the cellulose in the prod. The starch an amylopectin content >=60%. A viscose soln. contg. 5-25% dissolved starch, based on the wt. of cellulose can be extruded to give fibres which are stretched >=50% to give a prod. with tenacity >=2g/denier. Viscose contg. 5-100% dissolved starch, based on the wt. of cellulose, and anionic polymer or polyvinyl-pyrrolidone can be extruded in fibre form and coagulated to give a prod. with increased fluid holding capacity. The starch has an amylopectin content as above. The starch soln. and starch-viscose mixt. have good filterability. The fibres are obtd. in a high yield, can be washed repeatedly, dye well, are resistant to starch removal and behave well in processing, e.g. high speed carding. They can be used in e.g., home furnishings, clothes, sheets, towels, hose reinforcements and absorbent materials.

Title: Robinet a soufflet
IPC: F16K1/00
Filed: 1979-03-13
Abstract: L'invention se rapporte aux robinets. Le robinet suivant l'invention est du type à soufflet qui comprend un corps A surmonté d'un chapeau 40 et commandé par exemple par un bouton fileté C qui agit sur une tige 62 terminée par un clapet 64, et rappelée par un ressort 150. Le joint entre la tige et le corps du robinet est fermé par un soufflet 68 interposé entre la tige 62 et un adaptateur B vissé dans le chapeau- 40. Suivant l'invention l'extremité avant du soufflet est soudée sur la tige et son extrémité arrière est soudée sur l'adaptateur. Le soufflet travaille alors à la compression ce qui rend le robinet capable de supporter des pressions nominales plus élevées. Le tampon 118 est en matière tendre ou souple (amélioration de l'étanchéité). Il est rapporté dans le clapet et fixé par repoussage en 122 après le soudage du soufflet, exécuté sous gaz inerte. Principales applications : robinets industriels pour fluides agressifs, hautes pressions et hautes températures.

Title: Filter partic. for extra-corporeal blood circulation installation - allowing filtration of several streams with elimination of froth
IPC: A61M1/36
Filed: 1979-04-03
Abstract: Device for filtration and elimination of froth for an extra-corporeal blood circulation installation comprises an enclosure sepd. by a partition into two compartments. The upper compartment constitutes a collector connected to several inlet pipes and a vent pipe. The lower compartment constitutes a reservoir connected to an outlet pipe. The compartments are sepd. by a filter. The upper compartment contains a filtering mass which divides it into several independent chambers into each of which an inlet pipe opens. The filter mass separates each of these compartments from the vent pipe and from the orifice of communication with the lower part. The device does not present the inconveniences of existing devices for eliminating froth and filtering blood in an extra-corporeal circulation installation. These include deflectors in the upper compartment intended to orient the streams of blood to prevent mixing of these streams. However, this mixing is produced and leads to a supplementary formation of froth and contamination of the streams. In addn. the circulation in the upper compartment is rough and the blood can lose its cohesion. The device according to the invention is simple and not costly.

Patent FR-2450730-A1 (FR)
IPC: B61C17/00
Filed: 1979-05-08
Abstract: The vehicle has at the front or at the front and at the rear in each case one end-wall part (7) which is inclined from the ground part (3) towards the roof part (4) and the centre of the vehicle and is provided with two or more air baffle plates (8) which project in a web-like fashion and run parallel to the longitudinal central plane of the vehicle. By means of these baffle plates, the air which is displaced at the tip of the vehicle is prevented from flowing away laterally and the resulting bow wave is guided away upwards along the end-wall part (7). In the region of the end-wall part (7), flow in planes parallel to the longitudinal central plane of the vehicle is brought about. One embodiment has movable air baffle elements which are adjustable between a position which has the effect of guiding away the bow wave upwards and a position which does not have this effect. According to further embodiments, the end-wall or parts of the same can each be adjusted between two differently inclined positions.

Title: Drying system for bulk cereal - uses vibrations and moisture removal and applies mechanical impulses from electromagnetic field of given duration and interval
Inventor: LEVIN IGOR ANATOLIEVICH
IPC: F26B5/02
Filed: 1979-10-02
Abstract: The drying system for bulk cereal introduces vibrations in the material and then draws off the moisture released. The bulk material (2) is subjected to mechanical pulsation to produce separate pressure waves. The mechanical pulses are generated by an electromagnetic field. The mechanical pulsating effect is produced by a group of synchronized electromagnetic pulses. The pulse duration of the individual pulses of the field lie within 10 power -5 and 10 power -2 see, and the ratio between the pulse interval and the pulse duration lies between 1000 and 10,000. The vibrating mechanism (3) is produced by eddy current inductors (10) connected to a source (4) via an energy store (13), a switch (12) controlled by program commutators (11).

Title: Rear door closure for communal transport vehicles - has display plate with integral lock for rear door when children are carried
Inventor: BAILLEUX GILLES
IPC: E05B65/20
Filed: 1979-10-08
Abstract: The rear vehicle door can be opened in the usual way when carrying adults, but when children are being carried the door can be opened only from the outside or by a driver operated cable. The extra security comes into operation when a plate 'children being carried' (8) is placed between four brackets. One of the brackets is spring loaded and insertion of the plate pushes down a bolt plate, so that the door cannot be opened across a hook (20) unless the hook is first lowered by foot pressure on a beam (19) or by a spring operated cable (21).

Title: Domestic central heating system - has heat exchanger as economiser in boiler chimney with circuit supplying water to boiler
IPC: F24D12/02
Filed: 1979-11-16
Abstract: A conventional boiler (9) supplies radiators (11) with hot water through a four way control valve (12). A pump (13) circulates the water. A heat exchanger (8) is fitted in the flue from the boiler. Water is circulated through it by a separate pump (13) in a subsidiary circuit from the boiler flow and return connections. This circuit acts as an economiser for the boiler. The heat exchanger consists of a flow header tube and a return header tube with a bank of cross tubes between them. The tubes and headers may contain baffle inserts to promote turbulence to increase heat transfer.

Title: Extrusion nozzle with sliding baffles - to choke and baffle the flow for positive control of the flow area circumferentially
Inventor: FIGUEREO BLAISE FRANCOIS
IPC: B29C48/09
Filed: 1979-12-19
Abstract: Extruder nozzle which receives material via an annular array of parallel passages leads to a convergeant passage having a depth which can be throttled by an array of trapezoidal baffles which can shift individually parallel to the extrusion axis and which have a face deep enough to locally seal the local input passage. Alt. the baffles can retract sufficiently for the convergeant passage to equal or exceed the combined area of the input passages. Two alternative outlet die designs are described to follow the nozzle chamber with the sliding baffles; each has a support plate with parallel passages for accepting the output from the baffled passage and which carries two or three concentric collars to define the outlet passage relative to a core mandrel which calibrates the bore of the extruded profile. Used for mfr. of hollow or solid profiles, to control the throughput rate and to balance the flow rate circumferentially. Pref. used instead of pivoting baffle plates deflected by the flow pressure until an adjustable mechanical stop is reached, since the positions of the baffles can be more positively set and aligned and are not susceptible to change by variations in melt pressure.
