Title: Graphite anode for chlorine manufacture - with good wear resistance
IPC: C04B35/52
Filed: 1970-07-22
Abstract: Pores in graphite are filled with non-graphitising vitreous C. This can be produced by baking and carbonising synthetic resin of furfural, acetone/furfural, phenol/furfural, di- or tri-vinylbenzene, phenol/-formaldehyde, furfuryl alcohol, vinylfuran, polyester and/or epoxide type, by heating above decomposition temp. Graphite is impregnated with resin, which is cured, then baked and carbonised at 350-3000, pref. 700-1600 degrees C. Vitreous C causes great reduction in wear of graphite anode, although it is unsuitable for use as anode alone, since it cannot be used at high current density, has poor mechanical strength and cannot be produced in massive form.

Title: Iron making or steel making process
Inventor: WALLACE VOICE ERNEST
IPC: C21B13/08
Filed: 1970-12-03
Abstract: A refractory lined horizontal rotary furnace is rotated at such speed that the liquid and solid furnace contents, e.g. liquid iron and solid coal or coke, or liquid steel and solid slag forming additions, are maintained around the internal furnace wall by centrifugal force. The non metallic material is mixed with liquid metal by chaning the rotational speed of the furnace by accelerating it. The furnace is maintained at the higher rotational speed until further mixing is required when the furnace is decelerated and then immediately reaccelerated.

Title: Stress-free rolling mill - with beams to transmit roll force direct from chocks to tie rods at each side
Inventor: THEOBALD WALTER
IPC: B21B31/04
Filed: 1972-10-26
Abstract: The beam rests on the upper roll chock and fits round the tie rods at each side, its upper surface being in contact with the under surface of the nuts on the screwed end of the tie rods. The normal screw down spindle is used to act on the centre of the beam, and thence on to the roll chock for positioning the rolls initially.

Roll forces are taken by the tie rods so that the housing can be more simply and lightly constructed. Roll press. is continuously measured and used to correct for variations in load by electronic/hydraulic control.

Title: Artificial kidney has porous membrane parallel to flow - giving effective filtration of particles smaller than pore size
Inventor: KAMIDE KENJI
IPC: A61M1/34
Filed: 1972-11-21
Abstract: An artificial kidney comprises a membrane filter having pores of diameter 0.01-0.10 mu and arranged parallel to the flow direction of the blood stream. A pressure difference sufficient to cause filtration is applied across the membrane. The membrane may be arranged flat or cylindrical. Its outlet side may be connected to a buffer soln. circuit. It may be prepd. from cellulose acetate. Particles having mol. wts. in the range 40,000-50,000 although they would pass through a filter of the above pore size if it were arranged transversely to the flow direction, are effectively retained by the filter when it lies parallel to the direction of flow. The vortex radius only needs to be 1/10 of the pore size to prevent practically all the particles from passing through the filter.

Title: By-passing preventing device for called number barring cct. - ccts are built into telephone with key dialling
Inventor: ADOLPHS DIETER DR ING
IPC: H04M1/677
Filed: 1973-09-19
Abstract: Switching means are provided at the microphone capsule, which block, in their rest state, speech transmission. The barring circuit delivers, on recognising a permitted number, a criterion which operates the above switch, so that speech transmission is possible. An amplifier near the receiver passes signals only towards the receiver. The object is to prevent the misuse of the key dialling signals whereby the normal dialling apparatus of a call box telephone, or any telephone using coin payment, is circumvented, and a connection made to a barred number. The invention provides an inbuilt device and avoids the necessity of complicated and costly circuitry.

Title: Cage-built stepping selector - cage support stator contacts at ends of arms
Inventor: HEINZ RUDOLF
IPC: H01H9/00
Filed: 1973-10-04
Abstract: Stator switch contacts connecting transformer tappings are supported in groups around a circular path. They are situated at the ends of arms extending peripherally from a central vertical limb, which is aligned axially with the rotor. These tree-like structures form the bars of the cage assembly and are case or mouled, as oe piece, in resin plastic, the invention allows a stronger tight contact for selective switching of higher voltages and therefore, if necessary, a smaller scale of construction. This characteristic is created by the single construction which not only increases the travelling path between two neighbouring contacts, namely double the length of an arm, but also improves the mechanism solidity and the simplicity of manufacture.

Title: Cockcroft-Walton voltage tripler for television receivers - has capacitor pairs formed by single roll of dielectric and metal foils
Inventor: PETRICK PAUL DR
IPC: H02M7/10
Filed: 1974-04-26
Abstract: The Cockroft-Walton voltage tripler, for television receivers, has its capacitors grouped into pairs and formed by a single roll of dielectric and metal foils. Each roll therefore contains two capacitors and simplifies the assembly of the final voltage tripler. External connections leading to and from each roll are connected via the diodes to the connections leading to and from another roll. The odd capacitor may be included in one of the rolls to give a single roll containing three capacitors. Combining the capacitors in pairs in this way reduces the time required to assemble the voltage tripler (or doubler).
