Title: Clamp for aligning and holding two pipe sections - positions pipes for internal welding by rotating laser beam
IPC: B23K37/053
Filed: 1977-03-04
Abstract: An internal clamp for holding securely the adjacent ends of two pipe sections or similar hollow details which are to be welded together, is applicable on land or on pipe-laying ships with laser welding devices. It has two supporting cylinders, each of which can be inserted in one of the pipe ends. Each supporting cylinder has outwardly expandable clamps. A hollow arbor carries the supporting cylinders, which are spaced some distance apart. The arbor is free to rotate relatively to the cylinders and has a window in line with the space between he clamp support cylinders, so that a laser beam can be projected through it and form a complete internal joint whilst the arbor turns through 360 degrees. The clamp can hold two adjacent pipe sections and if necessary bring them into contact. At the same time it has sufficient power to expand both sections to the same dimension and alignment so that a good welded joint can be made.

Title: Anaerobic treatment plant for effluent - with circulation from digester to settling tank induced by methane gas rising in central column
IPC: C02F3/28
Filed: 1978-02-06
Abstract: Water-borne effluent is treated anaerobically in a vessel comprising a digestion chamber equipped with a feed for the effluent, above the digester, a pptn. chamber with a central opening and an inclined floor, a column rising through the central hole in the floor of the pptn. chamber which overflows into an annular space between the column and a sleeve, a gas collector and an overflow for clean water. The bottom of the central column is dished outwards so that the methane gas generated flows into the column and induces a circulation of liq. upwards through the column and over the overflow. To ensure that effective sepn. of the gas from the liquid takes place in the annular zone, a flocculant is pref. added. The water and sludge flow beneath the lower lip of the sleeve into the settling chamber. The floor of the chamber is pref. inclined down toward the central opening to ensure that the sludge flows out between the central column and the lower edge of the floor. For larger treatment plants where this may be impractical, the floor is equipped with a mechanical sludge scraper. Due to the construction of the central rising column and the arrangement of the settling chamber and digestion chamber, short circuiting of the digestion and settling streams is avoided. By adjusting the vertical position of the column, the throughput can also be regulated.

Title: Dual rate voltage regulator for engine driven DC generator - has two switches and actuators for quick start=up charging to predetermined level
IPC: H02J7/24
Filed: 1979-01-19
Abstract: The voltage regulator includes a first normally closed switch arranged for releasably connecting the field coil terminal of an engine-driven DC alternator or DC generator to its appropriate positive or negative output terminal. The first switch is controlled by an electric actuator having an electric circuit arranged for connection across the output terminals of the alternator or generator. It is operable at a predetermined lower level output voltage to open the first switch. The output charging voltage is thus limited to the lower level which is predetermined to effect charging of the battery without significant consumption of water. A second actuator is operable at a predetermined higher level output voltage to close a second switch and activate the first switch actuator. The higher level is predetermined to effect charging of the battery quickly.

Title: Multichannel frequency converter for communications signals - distributes cable TV signals to users simultaneously using reference oscillator and PLL
IPC: H03D7/00
Filed: 1988-02-16
Abstract: The converter is used to process signals of communications channel width greater than that of narrow-band signals. The converter can handle several, e.g. five, ten, twenty or more, channels at a time, forming output signals which have frequencies equal to the difference between input signals and the frequency of a reference oscillator. The reference oscillator uses phase-lock loop techniques to generate a frequency free of sub-harmonics. The converter is intended for use with cable TV inputs signals which have frequencies below 450 MHz, and can convert them to frequencies above 450 MHz intended for the end-users of the system.

Date Dec. 18, 1986.Process for recovering chemicals and energy from cellulose waste liquors preferably black kraft liquor obtained in a paper pulp sulphate process, comprising the following, three distinct and separate steps: In the first step the concentrated black liquor is gasified in a pressurized gasification reactor by so called flash-pyrolysis at 700 DEG  to 1300 DEG  C., normally 800 DEG -900 DEG  C., whereby an energy rich gas is produced, and in which the inorganic chemicals of the black liquor are contained in the form of molten suspended droplets, mainly comprising sodium carbonate and sodium sulphide. In the second step the gas from the gasification reactor is rapidly cooled through direct contact with water, and with green liquor, which is formed when the molten droplets and the hydrogen sulphide are dissolved in the quench liquid. The cooled gas subsequently passes through a scrubber. In the lower section of the scrubber the gas is washed with circulating green liquor, and in the upper section of the scrubber the gas is washed with sodium hydroxide (or carbonate) solution and water for complete removal of any remaining sulfur bearing components in the gas. In the third step the now sulfur and particulate-free gas is used as a fuel for generating steam and, if it should be economically justified, also for production of electric power.
