Patent FR-2222017-A1 (FR)
Title: Suction filleting machine for fish - while held between edges of rotating plates
IPC: A22C25/16
Filed: 1973-03-21
Abstract: Machine is intended for treating fish which has previously been immersed in brine to render the flesh more flexible. It consist of three rotating plates, on of which is a handling plate and the other sepg. plates. The edge of each plate is provided with a large number of regularly spaced holes which may be connected in turn to a vacuum pump, a source of compressed air and to a water supply under press. The first plate holds the fish to its side by suction until it comes to plate two. This picks the fish up until contact is made with plate three when the fish is engaged in the gap between the plates which rotate in opposite directions. The flesh of the fish is held on each side and the fishbone is released; it is guided to an evacuation point while the fillets are ejected by the compressed air to suitable handling means. Water under press. removes any particles that might block the holes. The process operates at an economic rhythm and recovers the max. amt. of flesh without manual intervention. It can be used in canneries, on fishing boats and in fish-packing stations; it can be incorporated in existing prodn. lines.

Title: Preventing corrosion and dust deposition by gas effluents - in glass-melting installation by injecting alkaline powders into gas ducts
Inventor: KIKUCHI MAKOTO
IPC: B01D53/34
Filed: 1974-09-19
Abstract: Corrosion of effluent gas ducts in glass melting installations is suppressed by uniformly introducing into the aggressive effluent gases a finely pulverised cpd., pref. an oxide or hydroxide of Mg,Ca,Na or K. The powder (5-10 mu, pref. 10 mu) is injected into the gases in an amt. of 1-10 mg.equiv/Nm3 (pref. 4-8 mg. equiv./Nm3). Corrosive sulphuric vapours and particles of low-melting pyrosulphates or bisulphate of Na,K, and also their carbonates, sulphates, etc. contained in effluent gases from glass-melting installations, react with each other when the temp. of the gas phase drops below 460 degrees C forming low-melting substances corroding the installations and forming deposits reducing the heat transfer rate. Iron is attacked by the pyrosulphates and bisulphates of Na and K with formation of FeSO4. The injection of the oxides or hydroxides of alkali(ne earth) metals neutralises the acid components of the gas effluents; high-melting neutral sulphates are formed; corrosion is prevented; deposn. of dust is reduced because the particles of the high-melting sulphates are not tacky of temps. below 460 degrees C.

Patent FR-2292319-A1 (FR)
Title: Low noise switch with gradual action - uses potentiometer system to reduce transmitted voltage to zero before breaking contact
IPC: H01C10/50
Filed: 1974-11-19
Abstract: The push-button (1), when depressed, allows an arm (4) to slide along a linear potentiometer whose voltage progressively falls reaching zero when the button is fully depressed. At this point the arm (6) breaks contact. As the button is released contact is made agains at (6) and the arm (4) slides to its original position gradually increasing the potentiometer voltage to fall. This method of switching can be used in low frequency work where noise resulting from switching is to be avoided. This technique can be adapted to bring many circuits into operation simultaneously and also to operate in a rotating fashion. Sudden changes in resistance and sparking are avoided.

Title: Cigarette holder and filter - has deflectable membrane valve and tar trap to permit free flow of tobacco smoke
IPC: A24D3/04
Filed: 1975-07-25
Abstract: The cigarette filter has a smoke channel, closed in the rest position, which opens on inhaling the smoke as a function of the suction produced in the smoke channel. The filter has a cylindrical body (1) of rigid transparent or translucent material, one end (1a) of which is widened to hold the cigarette. The lower end of the filter body (1) is closed (1b) with symmetrically arranged apertures (1c). A flexible member (4) if fixed to a central shaft (5) and is gripped between the ribs (1a) moulded to the body (1). When a cigarette is inserted in the supporting chamber (3) and the smoker inhales, the membrane (4) moves away from the wall of the recess. The tobacco smoke passes through the resultant annular space, and tar is deposited in the recess (6) and cannot be carried along the smoke channel (2). No build-up of deposits causing resistance to flow can take place, and the filter can be used with a succession of cigarettes before it has to be discarded.
Patent FR-2282287-A1 (FR)
Title: Two part filter medium - giving much reduced rate of increase of pressure drop per unit area
IPC: B01D39/16
Filed: 1975-08-18
Abstract: The rate of increase of pressure drop across a filter medium is reduced so that more liquid can be filtered before the filter is cleaned, by using a basic filter medium made of fibres of a fixed dia. woven into a felt of known pore dia., thickness end density. An unwoven mat of fibre is formed upstream of the basic medium an in contact with it. The fibres have the same dia. as those in the basic medium within plus-or-minus 40%. The mat is at least ten times thicker than the basic medium and its density is at least ten times less. Used in filtering liquid-solid mixtures. The amount of liquid filtered over a unit area before the pressure drop becomes excessive is increased about 100%.

Used in winning Ga from solns. obtd. in processing bauxite or nepheline. The Ga can be used e.g. in semiconductor cpds., dental alloys, or as conductors of heat or electricity. There is continuous prodn. of high purity Ga, where the magnetic field disturbs the film on the liq. metal cathode, improving the yield of Ga.
