Title: Refining phosphorus rich cast irons - by blowing with an oxygen/lime powder suspension
IPC: C21C5/32
Filed: 1972-10-02
Abstract: In a process for refining phosphorus rich crude cast iron to transform it into steel, a suspension of oxygen- and powdered lime is blown into the melt via a multiple orifice lance; 80% of the lime necessary is blown into the melt during the first five minutes, then pure O2 is blown until 70% of the blow time has passed and finally the remaining 20% of lime is blown in. The process uses lime normally used in steel prodn. to form a single slag without the need for special measuring appts. The steel produced has a final P content of 0.03%.
Patent FR-2207095-A1 (FR)
Title: Electrolytic chromium removal from effluent - obtd from chromating or passivating steel or from anodising baths
IPC: C02F1/467
Filed: 1972-11-17
Abstract: Effluents are treated to remove chromium prior to discharge by reducing hexavalent C2 to trivalent electrolytically in HCl or H2SO4 in the presence of a chloride the acid having a normality of about 0.5N. The negative potential on the cathode is maintained at a value insufficient to bring about reduction of the water. The yield of the reaction is close to 100% reduction of the hexavalent chromium present in the original effluent. The process is cheaper than the prior art process of reacting with sodium bisulphite or ferrous sulphate then precipitating with alkali.

Title: Image converter using a liquid crystal - provides clean septn. of light beams
IPC: G02F1/135
Filed: 1973-04-27
Abstract: Image converter comprises a nematic-liquid crystal and a photosensitive element in layers face to face and separated by an optical barrier. The device is exposed from the side of the photosensitive element, to light from an image to be converted and from the other to a beam of light for projection of the image. The appts. includes a source providing a potential difference between conductive layers on the inside faces of glass blocks which retain the assembly. A mosaic of small glass mirros is disposed on the face of the optical barrier in contact with the liquid, to reflect projected light. The optical barrier is made from a series of electrically conductive plugs insulated from each other and each in contact with one end of the small mirrors, and fixed at the other end to the photosensitive element. They are embedded in an insulating body forming the rest of the optical barrier between the plugs. The liquid crystal is retained in the cavity by stoppers. Septn. of the light beams is effected cleanly so that the image projected is an exact replica of the image received without distortion due to extraneous light.

Title: Slow speed control for marine transmission - has variable fluid flow distributor for clutch-slipping in hydraulic clutches
IPC: F16D48/04
Filed: 1974-03-29
Abstract: Normally a hydraulic clutch is either transmitting drive or not. This controller varies the amount of pressurised hydraulic fluid fed to the clutches and enables speeds lower than normal to be obtained by 'clutch-slipping'. The pump (3) feeds the clutches (4, 5) via a cylindrical hydraulic distributor (1), and a regulator (2) is inserted in the circuit parallel to the distributor. for normal load conditions the recess (1.1m) in the distributor valve corresponds to the port (1.2f) in the body but for slow speed leads out with a tapering portion which, when opposite the port, allows passage to a restricted fluid flow.

Title: Flexible pipe or cable clamp - has eccentric cable passages in relatively rotatable body and screw
IPC: F16G11/00
Filed: 1974-05-28
Abstract: The body (1) has an eccentric hole (t1), for the passage of the cable, expanding to a greater diameter hole (t2), and and the screw (2) has a hole (t3) similar to hole (t1). Tongues (4) project from the lock screw and retain it on the body by locating on a shoulder (5) of the latter when pressed into position. Teeth (8) formed on the inside of the lock screw mesh elastically with similar teeth (7) on the body. The cable is passed through holes (t1) and (t3) and the screw is pressed into position on the body. Rotation of the screw by hand elastically deforms the teeth and carries the cable round until compressed against the inside of the hole (t2). A milled exterior (9) of the screw facilitates turning by hand and radii (r) inside the body prevents damage to the cable.

Title: Pressurised container with a stable base - has part concave deformable base with inclined circumference
IPC: B65D1/16
Filed: 1974-08-28
Abstract: The container (22) has a bottom surface (26) in which there is a hollow (28) directed towards the interior. When the container is subjected to internal pressure, the material deforms so that the circular intersection line (30) between the bottom (26) and the hollow (28) acts as a stable base for the container. Deformation occurs by bending at the corner (24) between the bottom and the conical section between the bottom and sides. Between 15 and 60% of the surface area of the bottom is accounted for by the hollow. The angle (A) between the tangent to the hollow and the bottom at this intersection is between 43 and 90 deg. The conical section (32) can be omitted. Various metals are used.

Title: Gas washer using electrostatic charge - injects oppositely charged water spray into smoke, and removes droplets and particles in separator
IPC: B03C3/16
Filed: 1975-09-03
Abstract: The gas washer suitable for removing particles from smoke from foundries, furnaces etc. has a chamber (2) containing electrodes which charge negatively the smoke passing through the smoke conduits (1), and discharging into a vertical chimney (3). A water spray is injected through nozzles (4) through the chimney wall above the smoke entry. The droplets of the spray are fine enough to be in suspension in the gas, and are charged positively, so as to attract the particles. The nozzles are mounted inside tubes through the chimney wall so that a flow of air passes through with the droplets. At the top, the mixture passes through a branch pipe (5) connected to a separator (6) which retains the droplets, and passes the cleaned smoke. The injected spray also tends to absorb noxious vapours in the smoke.
