Title: Printing machine roll produced by expanding tube plastically - into cylindrical mould to give good symmetry without machining
Inventor: LINSKA RUDOLF
IPC: B29C49/22
Filed: 1974-04-18
Abstract: A method of making rolls for printing machines utilises as the starting blank a tube of a matl. which can be moulded; the tube is introduced into a mould having a cylindrical internal chamber of larger dia. than the external dia, of the tube; pressurised fluid is then introduced into the tube, deforming it beyond its elastic limit plastically to fit the mould. The tube, either before or after being placed in the mould, may have end discs fitted to it and sealed with a sealing ring and rolling in or swaging of the tube onto its end. Opt., a second, inner tube of smaller dia. than the first may be introduced and both deformed plastically together. The tube may have an external facing applied around it; this is slightly larger than the tube but smaller than the mould so that, as the tube is expanded this facing deforms elastically not plastically. Prefd. types of facing are of nylon, copper or stainless steel. Method is used, in parthic. for prodn. of fast running guide rolls for paper. The method produces a roll which has very good balance and does not require subsequent trimming or machining.

Title: Long-lasting dust suppression salt pastes - paste partial vapour pressure adjusted by salt content, specified formula
Inventor: LEWER HANS
IPC: E21F5/16
Filed: 1974-07-18
Abstract: Long-lasting hygroscopic salt pastes for dust binding in suppression of dust below ground in the mining industry comprises a gel support substance, hygroscopic salts, surface-active agents and water. The salt content is controlled to adjust the partial vapour pressure of the water to the average partial vapour pressure of the ventilating air in the workings. The value to which the partial vapour pressure of the paste is adjusted is found from the equation which includes the arithmetic mean temperature in the ventilating intake roads. The equation gives the required average value expressed in % and relates the length of the intake ventilating roads concerned, in metres to the relative air humidities in these same roads.

Title: Recovery method for a bandwidth limited signal - is from non-equidistant sampling valves
Inventor: RUPPRECHT W PROF DR ING
IPC: H04B1/66
Filed: 1974-12-17
Abstract: The scanning function is multiplied by the signal function. The scanning function consists of two component functions with equidistant scanning pulses, staggered by a certain fraction of a period. A specified function is derived and each second scanned value has its polarity reversed and the resulting signal limited to a bandwidth corresponding to the signal maximum frequency. Synchronous demodulation is then carried out by multiplication with the carrier frequency. The original signal function is recovered by a further bandwidth limiting to (+-) maximum signal frequency.

Title: Ignition and supply circuit for hot cathode fluorescent lamp - uses capacitor to momentarily raise DC supply level for ignition (NL130776)
Inventor: KREUTZER OTTO
IPC: H05B41/282
Filed: 1975-01-09
Abstract: The ignition and supply circuit for a hot cathode fluorescent lamp, supplied via a transistor inverter from a direct current source, has a capacitor charged from one of the inverter transformer windings via a rectifier. When the voltage across this capacitor reaches a given level, the capacitor is discharged by an electronic or mechanical switch into the inverter direct current circuit. This momentarily increases the supply voltage and ignites the fluorescent lamp. Two diodes are coupled in series with each of the two heating filaments. This arrangement increases the lamp reliability, lifetime and load rate.

Title: Briquetting loose materials using explosive energy - in a device having actuating cylinders for briquette removal
Inventor: KONONENKO WADIM GRIGORIEWITSCH
IPC: B30B11/02
Filed: 1975-04-18
Abstract: A briquetting device which utilizes the impulse energy of detonation includes an explosion chamber provided within a housing having a piston and a finder assembly. The housing is movably mounted on a bed plate adjacent an anvil with a container arranged intermediate of the housing and anvil. A die is positioned intermediate of the anvil and container and integral with the latter. Rods provided within the anvil are connected rigidly to the die to move the die towards the housing after briquetting and so cause pushing out of the briquette by a plunger attached to the piston rod in the housing. Used for briquetting of steel turnings, titanium-base alloy turnings, concentrates and refractories. Briquetting can be performed in a vacuum or inert atmosphere. The device has an increased output since it enables auxiliary operations associated with setting of the device to be carried out simultaneously. The die design permits the briquetting of fine, disperse loose materials.

Title: Ingot casting procedure - in electroslag furnace without forming deep molten metal cores
Inventor: ROBERTS RAYMOND J
IPC: B22D23/10
Filed: 1976-02-12
Abstract: A number of ingots are cast in a furnace comprising a main mould section, in direct open communication with a number of ingot mould sections having a total cross-sectional area less than the main mould section cross-sectional area, an electrode, and a conductor disposed outside the ingot mould sections. A pool of molten metal is formed in the main mould section and maintained by directing an electrical current through the electrode and conductor. Molten metal flows from the pool into the ingot mould sections and is prevented from freezing at the interface between the main mould section and the ingot mould sections. Current is prevented from entering the molten metal in the ingot mould sections. The method is used to cast a number of ingots from a pool of molten metal without the formation of deep molten metal cores in the ingots. Ingots of satisfactory metallurgical quality can be cast at increased solidification rates, resulting in more efficient furnace utilization and decreased production costs.
