Title: Method for the continuous forming of butted pipe from flat material
Inventor: HESS WALTER
IPC: B21C37/08
Filed: 1982-11-29
Abstract: The invention relates to the continuous forming, independent of dimensions, of flat material to a butted tube, normally with a forming length of at least 20 x the diameter of the finished pipe. In order to shorten the forming train and to obtain a butted tube without undulations for the welding process, the invention provides for the forming of the first stage to take place up to in front of a first guide stand (6) steadily to a cross-section, as shown, in stands having vertically adjustable rolls 2 and horizontally and vertically adjustable edge guiding rolls 1, 3. <IMAGE>

Title: A magnetic anomaly detector
Inventor: SEANEY ROBERT JOHN
IPC: G01V3/08
Filed: 1983-02-16
Abstract: A detector capable of detecting magnetic field gradients that are too small for detection by conventional magnetometry techniques is described. The voltage signal induced by a magnetic field gradient across a rotated D-shaped coil (8) is converted to an optical signal in a self-powered transmitter (12) rotating with the coil and transmitted via an optical slip-ring including transmitter (13) and receiver (14) to remote processing and indicating circuits (15). In a method of using the detector for locating buried ferrous objects, the burial ground is first swept with a magnet so as to magnetise the objects, into saturation if possible, and thereby maximise the magnetic field anomalies for subsequent detection. <IMAGE>

Title: Lockable toggle switch
Inventor: KIRCHOFF FRANCIS DONALD
IPC: H01H3/20
Filed: 1983-03-29

When the sleeve detent (33) is retracted out of a recess, the lever can be moved to another switch position and the sleeve detent allowed to spring back into the new recess for re-locking the lever. <IMAGE>
Patent GB-2117893-A (GB)
Title: Hot air heating system
Inventor: BRAUER ROBERT C
IPC: F28D21/00
Filed: 1983-04-05
Abstract: A hot air heating system utilizes the otherwise wasted heat and moisture in the gases of combustion to pre-heat and humidify the room air. The hot flue gases discharged from the furnace are mechanically induced by a blower to pass through an auxiliary heat exchanger 5 in countercurrent flow to the cold air being returned from the rooms along duct 3 to the furnace, thereby pre- heating the return air and cooling the exhaust combustion gases. The products of combustion include a considerable quantity of water vapor. Cooling these gases results in condensation of this water, which is then collected in a sump 14 and utilized to humidify the room air. Condensation of the vapors releases their latent heat of vaporization adding considerably to the heat recovery of the system. Because the water does not contain any minerals the humidifier does not have the usual problems of mineral deposit build-up. <IMAGE>
Patent GB-2138891-A (GB)
Title: Mounting rotor blades
Inventor: JULIANS RONALD WILLIAM
IPC: F01D5/30
Filed: 1983-04-29
Abstract: Rotor blades 13 in an axial fluid flow machine, such as a turbine or compressor, are fixed to the rotor 3 by means of pins 15 which pass through bores 19a, 19b provided in the root portions 11 of the blades. In order to avoid point contact between the pins and the bores during operation of the machine when the blades twist on the pins under a combination of centrifugal and aerodynamic forces, the pins are made effectively barrel- shaped (or the bores are made a waisted shape) so that the contacts between the pins and the bores are lines which are substantially helical about the centre-lines 33 of the bores. This reduces stress per unit area of the bores. <IMAGE>

Title: Production of aluminium alloy
Inventor: MERCHANT HARISH D
IPC: C22F1/04
Filed: 1983-07-15
Abstract: Non-galling, low earing can stock suitable for deep drawing and wall-ironing into can bodies is prepared from continuously cast aluminum alloy strip of an inch or less in thickness. The strip material is heated to a temperature of from 950 to 1150 DEG F for a time sufficient to homogenize the alloy. The homogenized strip material is cold rolled to effect a first reduction in sheet thickness of at least 25%. The cold rolled sheet is heated to a recovery temperature of up to about 550 DEG F, and subjected to a second cold rolling to effect a reduction in thickness of up to 30%. The cold rolled sheet product is heated to the recrystallization temperature and then subjected to effect a final reduction in thickness of at least 50% of the original thickness of the sheet to impart an H19 temper to the sheet. When aluminum alloy 3004 modified with 0.1 - 0.4% by weight chromium is used in the process continuous strip cast aluminum sheet is obtained which is suitable deep drawing and ironing into high buckle strength two-piece beverage containers.

Title: Cutting tool for use in the milling of, for example, asphalt roads
Inventor: LUNDQVIST KELD
IPC: B28D1/18
Filed: 1983-08-24
Abstract: When asphalt is desired to be reused, the used asphalt is milled up with cutting tools which must be very resistant against wear. The actual milling tool consists of a cutting tool (3) of hard and brittle material which is supported in a holder (1) of less brittle and wear-resistant material. Many such tools are disposed along the circumference of a rotor. The tools are mounted in an inclined manner and are free to rotate around their longitudinal axes. With this known technique, the cutting tool falls out when it has been half worn away. According to the present invention, a technique is presented by which the tool can be held until it is almost completely worn away.

Abstract: Disclosed is a safety and kill valve device useful in tubing above a packer set above a producing formation in a well, operable to shut off tubing flow and open wall flow passages 27a to the well annulus through which heavy formation killing fluid may be pumped into the tubing. A lower ball valve 45 is used to shut off tubing flow and an upper sleeve valve 37,41, cooperable with the ball valve, controls flow through the wall flow passage 27a. An operating tube 15 moves downwardly, opening the ball valve and closing the sleeve valve while compressing a spring 17. The compressed spring furnishes operating force to move the operating tube upwardly, closing the ball valve and opening the sleeve valve. Two embodiments operate automatically in response to higher well annulus pressures. Another embodiment may be controlled through conduit from the surface or operate automatically in response to higher annulus pressures. All embodiments may operate repeatedly without retrieving from a well. <IMAGE>
