Title: High accuracy dispensing pump for chromatography - has plungers held in contact with swashplate with curved track to reduce inaccuracy
IPC: F04B1/29
Filed: 1980-05-14
Abstract: The liquid dispersing pump requiring a high degree of accuracy, such as for chromatography has a rotating base with a spindle (6) projecting from its centre which can be raised and lowered to vary the angle of a swashplate (4). A number of plungers (2) are forced down against the surface of the swashplate by springs (3), to control the delivery of fluid to a corresponding number of supply points. The angle of tilt of the swashplate determines the quantity delivered. In order to eliminate inaccuracies introduced when a flat swashplate is used, the rounded tips (26) of the plungers are held in contact with the convex surface of a circular track (7a) around the flat surface (4a) of the swashplate, giving point contact. The swashplate can be tilted about its horizontal hinge axis (5) by the movement of a tongue (40) projecting from its periphery, in contact with a cam surface (9) which can rise and fall below.

Title: Alignment jig for optical fibre and integrated waveguide - uses blocks supporting plates with V=shaped grooves for fibre and micromanipulator controlled for Precise positioning
Inventor: KAYOUN PIERRE
IPC: G02B6/30
Filed: 1980-12-29
Abstract: The arrangement uses blocks (A1,A2) to support monocrystalline silicon plates (2,32) in which V-shaped grooves are formed by chemical action. The grooves house the optical fibres (4,34) while the integrated optical circuit (1) is supported on a block (6) between the optical fibre support blocks. The blocks have their mating surfaces polished to reduce friction and thus to facilitate precise movement in three axes by micromanipulators operated from control knobs. One optical fibre support is positioned initially using an optical eyepiece. This support is then prealigned with the base of the integrated circuit support prior to alignment of the other fibre and the integrated circuit. The optical fibres are locked in position by screws (16) operating on clamping pads while an adhesive contact material is introduced between the fibres and integrated circuit.

Title: Cleaning and restoring objects of biodegradable material - e.g. archeological artifacts, by vacuum impregnation with thermoplastic polymer compsn.
IPC: B27K3/15
Filed: 1981-05-11
Abstract: Method for cleaning and restoring objects made of biodegradable material comprises placing them in a closed container, establishing a slight vacuum, then impregnating under vacuum with an aq. liquor contg. thermoplastic polymer. The vacuum is broken, contact with the liquor maintained and then the object wiped with water and dried. The impregnant is a soln., dispersion or emulsion, esp. a 5-50 wt.% polyvinyl acetate soln., and the vacuum impregnation is at 400-700 mm for at least 30 min. This is followed by contact for at least 1 hr at normal or slightly elevated (0.1-1 bar) pressure. The method is used to renovate shaped objects made of wood or limestone, clay etc., e.g. old pictures or furniture or items of archaeological interest. The process preserves the characteristics and external appearance of the objects and significantly improves the mechanical strength of objects which have undergone deterioration.

Title: Rotary cutter for machining radiused channels in insulation blocks - braced radially and axially against vibration
IPC: B27B5/12
Filed: 1981-06-17
Abstract: Annular rotary cutter for machining radiused channels in low density materials is driven by a belt running in a circumferential recess and applying tension along the belt circuit axis which is opposed by a pair of supporting rollers which engage the circumferential recess where it is exposed within the belt circuit. Suitable for cutting channels in blocks of insulating material, such as expanded polystyrene, e.g. to produce split elbow profiles for enclosing pipework bends. The opposing compressive radial thrusts on the cutter steady it against vibration or chatter and associated noise, roughness of cut, etc.

Title: Bottle contg. photographic developer or similar chemicals - where height at which opaque bottle floats in test liq. is used to indicate vol. of chemical left in bottle
Inventor: BERNHARDT RAINER
IPC: G01F23/00
Filed: 1981-06-22
Abstract: The bottle can float in a test liq. which may be a water bath used to control the temp. of the chemical in the bottle; and one of the walls of the bottle is provided with a graduated scale indicating the vol. of chemical in the bottle. When the bottle is placed in a test liq. or water, the extent to which it floats is determined by the Archimedean pressure; and the level of the test liq. is used as a reference mark to read the graduated scale. When the bottle is full, it will sink to a much greater depth in the test liq. than when it is partly or completely empty, i.e. the depth is proportional to the amt. of chemical in the bottle. This fact is used in constructing the graduated scale. The bottle may be made of an opaque polymer. A photographic developer soln. sensitive to light is kept, e.g. in an opaque, black polymer bottle, so the contents are invisible. But the invention indicates the amt. of liq. left in the bottle.

Title: Rotary contactor for welding robot - compressed air fed to resistance welding tongs also being used to press sliding electrical contacts together
Inventor: TRIBOUILLOIS PIERRE YVES
IPC: B23K11/36
Filed: 1981-07-17
Abstract: The contactor includes two stationary blocks fitted with inlet connector for providing services to welding tongs, e.g. compressed air, water and electric current. Inside the blocks is a distributor rotor with sliding contacts collecting the electric current. A device is used so one of the services being fed to the tongs exerts pressure on the sliding contacts. The pref. device consists of a blocking slide contg. a flexible hose and in which a blocking ring can slide. The hose is fed with compressed air by a tube, so that, during welding, the hose expands and the blocking ring exerts pressure on the sliding contacts. Efficient transfer of large electric currents.

Title: Epitaxial reactor with molecular jets - using an oxygen reactive layer to give a high vacuum
Inventor: FORTE-POISSON MARIE-ANTOINETTE
IPC: C23C14/56
Filed: 1981-08-21
Abstract: Epitaxial reactor includes an epitaxial chamber coupled to a means of pumping the residual gas; a sample area for placing a substrate onto which thin layers are deposited and the means of prodn. of the layers. These are produced by two cpds. of gp. III one of which is pref. Al and one cpd. of gp. V. The procedure for obtaining a high vacuum includes a stage in which a layer of a metal which is very reactive with O2, pref. Al, is deposited on the internal wall of the epitaxial chamber to tap the molecules of residual gas. The means of pumping the gas is by pref. a cryogenic pump and/or an ionic pump. An alternative form includes an envelope in the internal wall of the reactor to circulate a cooling fluid such as liq. N2. Used for epitaxial growth of type III-V semiconductors and with applications in microwave and opto-electronic appts. Improved vacuum is obtd. in an epitaxial reactor with molecular jets.
