Patent FR-2484858-A1 (FR)
Inventor: MUKOYAMA YOSHIYUKI
IPC: B01D15/08
Filed: 1981-04-16
Abstract: A description is given of a precolumn for liquid chromatography which comprises a cylindrical tube having a liquid inlet and outlet at both ends. In the cylindrical tube, the column contains a cartridge column which is packed with a dry packing material. The precolumn according to the invention is very effective in extending the service life of the main (chromatography) column if it is situated upstream of the main column. It can also be used on its own for various purposes if the cartridge column it contains is replaced or if the packing material in the cartridge column is replaced.

Title: Headed mandrel type hand riveter - has chuck moved by resulting movement of bar for setting rivet
Inventor: FUJIMOTO KAORU
IPC: B21J15/04
Filed: 1981-06-17
Abstract: The mandrel inserted through a rivet sleeve is pulled and snapped off its head by a riveter to deform the rivet sleeve for setting the rivet when a movable handlebar is pivotally moved relative to a fixed handlebar by hand. An operating bar pivotally supported by the main body of the riveter has one end pivoted to a chuck for gripping the mandrel and the other end serving as an engaging portion. A pusher is pivoted to the movable handlebar and has grooved portions engageable with the engaging portion. A bearing pivoted to the main body is formed with bearing grooves positioned alongside the grooved portions in corresponding relation and engageable with the engaging portion. When the movable handlebar is repeatedly turned, the pusher pushes the engaging portion in engagement with one grooved portion after another to engage the engaging portion correspondingly in one bearing groove after another.

Title: Threaded insert for soft materials - has chamfered square section and is moulded in two halves
Inventor: PELLIZZARI ROGER
IPC: F16B37/00
Filed: 1981-07-03
Abstract: The plastics threaded insert (4) is moulded in two symmetrical halves. The halves are joined by a strip of plastics, at the head (12). Prior to use they are folded and snapped together to form a threaded nut (7). The plan section of the insert is square with the corners champfered. The insert tapers and transforms into a circular collar (8). As the bolt (11) is tightened in the nut, it causes the latter to embed itself in the soft material (14) and due to its square section, rotation is prevented.

Patent FR-2513264-A1 (FR)
Title: Agitation of aq. cell suspension for laboratory or industrial culture - minimising shear stress by displacing inert fluid to agitate suspension
Inventor: MARCOVICH HERBERT
IPC: C12M3/02
Filed: 1981-09-22
Abstract: Agitation of the suspension is effected by an inert fluid which is immiscible with water. The fluid is pref. denser or less dense than water rather than being of the same desnsity. The inert fluid is pref. a liquid perfluorated derivative. Agitation of the inert fluid is pref. derived from a pumping system, a bar magnet or a bladed rotor. The appts. pref. comprises a culture vessel with inlet and outlet coupled to a pumping circuit. The pumping action displaces the inert liq. which in turn agitates the suspension. The vessel is connected to a supply of substances to support the growth of cells. Process control instruments e.g. pH metre, are fitted as desired. The inert fluid serves as a shock-absorber between the aq. suspension and the mechanical agitator. The agitation of the suspension is extremely gentle without harmful shear stresses.

Title: Foam layer camouflage of objects which emit infrared radiation - contains particles of graphite etc. and colouring matter
IPC: F41H3/00
Filed: 1982-02-16
Abstract: The object is covered with a layer of foam which adheres strongly to its surface. The foam is loaded with particles of a material which is highly absorbent of infrared radiation as well as colouring matter to provide camouflage in visible light. Pref. the particles substance has a high specific surface and a high refractive index, e.g. graphite of suitable particle size. Pref. the colouring matter is made up of organic and/or mineral pigments. The particles and colouring matter are pref. carried in an aq. soln. of emulsifier which is air-sprayed through a microporous wall to break the emulsifier. The coating is to camouflage objects which emit infrared radiation, e.g. human beings, vehicles, aircrafts. The coating provides a much better barrier to infrared radiation than aerosol sprays. It can be rapidly and securely applied to smooth walls, even when vertical. The coating remains effective over a wide temp. range.

Title: Drill bit for boring oil wells, mines, etc. - having rolling cutters with sealed lining comprising rigid ring and elastomeric sealing ring
Inventor: DEANE JOHN DARNELL
IPC: E21B10/22
Filed: 1982-05-13
Abstract: Drill bit for boring oil wells, mine shafts and mining works is described, of the roller blade type comprising several downwardly directed branches, each of which comprises (a) cylindrical journal which advances from each branch, (b) a cutting body mounted to rotate on each journal by means of bearing; and (c) a sealed lining placed between the cutter and the journal on the outside of the bearing device. Specifically, the solid lining (10) comprises a composite sealing assembly consisting of a rigid circular ring (11), with an L-shaped cross section on the outside of the which is formed a sealing face, (26) and an elastic sealing ring (12), adjustable without play on the pivot (14) and against the rigid ring (11). Appts. (29,30) is provided on the rigid ring and the pivot for preventing relative rotation between the rigid ring and the elastic sealing ring. The wheel (13) includes an internal shoulder surface (22) designed to come into rotational sealed contact with the sealing face (26) of the rigid ring (11). Wear of the elastic lining is reduced and hence chance of fouling up the cutter bearings with detritus from the boring is reduced.
