Title: Apparatus to control the position of rolled strip during rolling
IPC: B21B37/68
Filed: 1982-04-21
Abstract: The invention provides apparatus for the centering of a rolled strip during rolling, especially (though not exclusively) in the case of wide hot rolled strip. For this purpose, apparatus in accordance with the invention is provided with components (3) which are adapted to bear against the strip edges for the purpose of monitoring the lateral position of the strip, said components (3) incorporating means which are actuable to generate signals which in turn are adapted to energise adjuster-motors for varying the lateral position of the strip. Such adjuster-motors may be arranged either to displace lateral strip guides (15) or to pivot the roll shaft axis (14) of a set of rolls. The components (3) may comprise strain gauges connected in a bridge circuit. The lateral position of the strip may also be controlled by means ahead of the mill stand in response to displacements detected by photo-electric means. <IMAGE>

Title: Apparatus for reducing the moisture content of grain or other particulate material
Inventor: PALMER JOHN
IPC: F26B25/22
Filed: 1982-06-23
Abstract: A grain-drying apparatus 7, has a perforated grain-supporting floor divided into two downward inclines 9, 10 along which the grain is moved by the two runs 12, 13 of a trace 15. The bulk of the air flow 24 entering the dryer is drawn into the plenum chamber 25 by a cross-flow fan 26. This is augmented over the first three quarters of the grain travel by hot air (hatched arrows) from ducts 28, 29 and over the last quarter by cool air (dotted arrows) from cooling fan 31. The amount of hot air reaching the grain is regulated by appropriate shutters (not shown) each associated with a respective section of the floor 9, 10. These shutters are automatically controlled by a microprocessor or small computer. <IMAGE>

Title: Process for obtaining polymer/polyol products
Inventor: MELLADO MARIANO MALAGA
IPC: C08F220/44
Filed: 1982-08-02
Abstract: Vinyl copolymers in a polyhydroxyl solvent for use in the production of polyurethanes are produced by polymerising a mixture of monomers containing 70-90% acrylonitrile, 9-12% styrene and 1-9% of another vinyl monomer, preferably methylmethacrylate, in the presence of a free-radical catalyst and in a polyhydroxy compound, e.g. ethylene glycol, ethylene oxide/propylene oxide copolymer initiated by poly (active hydrogen) compound. The polymerisation is characterized by being effected at first under vacuum, with the pressure being allowed to increase slowly as the reaction proceeds. Monomers may be introduced continuously, with finally a heating stage to complete polymerization.

Title: Rubber sheet bonding apparatus
Inventor: SATOH KAZUO
IPC: B29C67/00
Filed: 1982-08-31
Abstract: A rubber sheet bonding device which supplies an unvulcanized rubber sheet (11) to a molding drum (1) mainly during the molding of a crude tire to bond it to the outer periphery of the drum (1) and to join it annularly to the peripheral parts. The rubber sheet (11) is supplied after the end of the rubber sheet (11) has been stretched by an appropriate amount so as to prevent the production of a joint that is inaccurate because of the shrinkage of the sheet (11), and the following rubber sheet is cut to the same length as the outer peripheral length of the rest of the drum during the stage of winding it around the entire periphery of the drum (1).
Patent GB-825138-A (GB)
IPC: B63B35/04
Abstract: 825,138. Laying submarine cables. POSTMASTER-GENERAL. Sept. 30, 1957 [July 20, 1956], No. 22633/56. Class 78 (5). Submarine cable laying apparatus comprises a series of pulleys arranged in tandem, together with mechanism for alternatively driving or braking them, the pulleys being so disposed that in the direction in which the series extends the cable contacting peripheries of adjacent pulleys do not overlap and the mounting being such that the relative position of each pulley in the series is maintained during cable laying. The driving and braking mechanism is selected from known types. A cable 1 containing a rigid repeater housing 2 is passed through the apparatus by connecting a hawser 3 across the section of cable containing the repeater housing, the hawser being shorter than the length of cable it bridges so that the latter forms a partial loop of slack cable. The hawser is passed through the pulleys 4 to 8 in place of the repeater section of cable and the repeater housing may be carried alongside on a trolley 9 or mat running in a track 10. The peripheral speeds of the pulleys may be the same, or alternatively differential gearing may be provided to avoid slip between pulleys and cable, when the latter stretches due to reverse bending. A device for automatically by-passing the section of cable containing the repeater to one side when it reaches the pulleys is described, as are several methods of severing the hawser from the cable after passage through the pulleys.

Title: Compressor diaphragm box seal
Inventor: ARLINGTON STERLING FREDERICK
IPC: F01D11/02
Filed: 1983-01-14
Abstract: A combustion turbine compressor diaphragm which has an outer shroud 30, an inner shroud 32 and radial vanes 20 disposed therebetween is provided with a channel-shaped boxed seal 30 support structure affixed to the inner surface of the inner shroud. The base 50 of the seal support structure includes a plurality of grooves 46 for receiving seal strips 48 which may be rolled into position and mechanically locked, such as by peening. Because the radial thickness of the seal support base may be increased over that of the inner shroud, the box seal increases the flexibility of seal design and improves the structural rigidity of the inner shroud. <IMAGE>

Title: Conference communications system
Inventor: FRAVAL ROBERT HANAFI
IPC: H04B10/114
Filed: 1983-12-22
Abstract: A conference communication system uses a card reader 34, accessible to each delegate, to read data on delegate identification cards held by each delegate. The identification data read by the card reader is transmitted to a remote location, for example the conference chairman's desk. The chairman is then able to select individual delegates to speak, the unit incorporating the card reader acting also as a speech transmitter and as a means for returning an authorisation signal to the delegate from the chairman. Signals are transmitted from the speech transmitter/card reader via an optical link and sent to a p.a. system 18, an interpretation unit 28 and a control unit 11 as well as to the chairman 12. Information is returned to other delegates by an optical link to individual headsets 32. <IMAGE>

Patent GB-2161766-A (GB)
Title: Servo motor for power assisted steering gear
Inventor: RAYNER ALAN
IPC: B62D5/12
Filed: 1984-07-20
Abstract: A fluid pressure servo motor for a power assisted, steering gear has inlet/exhaust passages to the opposed pressure chambers each provided with a valve member 13 that is displaceable in a bore 5a to throttle fluid flow from its associated pressure chamber 1. With a fluid flow into the chamber 1, the valve member 13 is displaced to a first condition so that unrestricted fluid flow is permitted through passages 14, 15. When the chamber 1 exhausts, the valve member 13 is displaced into a second condition in which maximum resistance to fluid flow is provided. This damps shocks and oscillations in the steering system. When the exhausting fluid pressure on the valve member 13 exceeds a predetermined value the valve member 13 is displaced into a third condition where control passages 16 open so that relatively unrestricted fluid flow from the chamber 1 is permitted. This allows normal power-assisted steering. In modifications the control passages are formed in the bore 5 and restricted control passages can be provided which alleviate the requirement for the through passage 14. <IMAGE>
