Title: Permeable nozzle method and apparatus for closed feeding of molten metal into twin-belt continuous casting machines
Inventor: SZCZYPIORSKI WOJTEK
IPC: B22D11/06
Filed: 1990-10-23
Granted: 1999-05-04
Abstract: Method and apparatus for the feeding of molten metals through nozzles having gas-permeable walls, cooperating with twin-belt continuous metal-casting machines.  The closed-channeled, multi-passaged nozzles have gas-permeable refractory walls, allowing the escape of gases that may be dissolved in the molten metal and become expelled or liberated from it while the molten metal is flowing through the passageways in the nozzle.          Gaseous voids in the continuously cast product are thereby avoided, notably in aluminum casting as shown by experimental results to date.  The nozzles are made from gas-permeable refractory material having interconnected porosity -- that is, interconnected void interstices -- extending through the nozzle walls.          The interconnected void interstices are of sufficient size for allowing the passage of hydrogen gas through the walls, while being sufficiently small for preventing the leakage of molten metal.  The gas-permeable refractory material is relatively non-wettable by the molten metal.  For example, the nozzles are made of fibrous sintered refractory material -- for instance, fibers of alumina or silica intertwined and cohered within a major volume-percentage of interstitial voids, which provide the interconnected porosity.  Such fibrous material displays high resistance to thermal shock.  It is relatively compliant to nozzle clamps, with consequent resistance to breakage, while the coefficients of thermal conductivity and thermal expansion of such fibrous refractory material are advantageously low.

Title: Optical fiber and amplifier with a samarium-erbium doped active fiber
Inventor: GRASSO GIORGIO
IPC: H04B10/12
Filed: 1990-10-29
Granted: 1998-04-07
Abstract: An optical fiber and an optical amplifier, in particular for optical fiber telecommunication lines operating with a transmission signal in a predetermined wavelength range.  The amplifier comprises laser emitting active optical fiber doped with erbium and a further doping substance, distributed along the fiber.  The further doping substance has an absorption for a light having a wavelength lower than 1,540 nm substantially higher than the absorption that the further doping substance shows for a light having a wavelength varying from 1,540 nm to the upper limit of the predetermined wavelength range of the transmission signal.  Preferably, the further doping substance is samarium.  Samarium contained in the fiber is capable of absorbing the spontaneous erbium emission, which would constitute a noise source, thereby allowing a communication signal to be amplified in a wavelength range corresponding substantially to the tolerance range of the commercially available laser light emitters used as the communication signal source.

Abstract: The invention relates to chain structure comprising several form pieces (1) and a wheel arrangement comprising at least one drive wheel (7) for transferring the chain, which is formed of said form pieces (1). The bearing surface (1B) of each form piece (1) consists of at least one transverse opening (2) which is arranged to be situated near one of the articulations (4, 5), which opening consists of the contact edge, the bottom and the back edge. When the chain is in mesh said openings (2) of the chain co-operate with the transverse joint pins (9) belonging to said drive wheels (7). The free length of the joint pins (9) essentially correspond to the width of the form pieces (1), whereupon the contact area formed during the contact situation in said mesh of said pins (9) and the openings (2) essentially corresponds in length to the width of the form pieces (1). After said contact situation said pin (9) leaves the opening (2) of the chain from that end thereof which is on the side of the trailing edge. In said contact situation and seen from a direction perpendicular to the largest axial cross-sectional area of pin (9), the free area of said opening (2) is essentially larger than the cross-sectional area of the correspond-ing pin (9), whereupon said contact area is formed on that part of the contact edge of the opening (2) on the bearing surface (1B) which joins said bottom. Furthermore, the largest distance of said contact edge from the centre line (K), which goes through the centres of the holes at the ends of the form piece (1), is essen-tially larger than the corresponding distance of said trailing edge from said centre line (K).

Patent CA-2099204-C (CA)
Inventor: BROWN JAMES P
IPC: B61L23/16
Filed: 1993-06-25
Granted: 1997-01-07
Abstract: A coded railway track circuit apparatus is disclosed having the capability of operating during periods of low vehicle activity in a reduced power standby mode.  This is accomplished by switching circuitry which interrupts power to most of the components within the track circuit apparatus in response to the recognition by standby initiation circuitry of a preselected standby initiation signal.  Power to fail-over indicators which would normally be activated due to a power failure is also interrupted by fail-over interrupt circuitry.  During the standby mode, monitor circuitry remains active to recognize occurrence of a preselected wake-up signal.  When the wake-up signal is received, full power is restored, thus resuming normal operation.  Operation of the fail-over systems is also then re-established.

Patent CA-2127787-C (CA)
Inventor: LINZELL GEOFFREY ROBERT
IPC: B23K35/36
Filed: 1993-01-11
Granted: 2005-06-28
Abstract: The invention, the subject of our International Application PCT/GB 91/00950 provides a method of securing against lateral motion two bodies held in face-to-face asperity contact, thereby to make a join between the two bodies, in which method there is inserted into the interface between the two bodies a material that on minimal initial lateral relative motion of the two surfaces promotes rapid but controllable "galling" between the two surfaces, this galling binding the surfaces against further such motion. The present invention relates to improvements in galled joints generally, as well as more specifically both to an improvement of our earlier Application's method to facilitate its use over a wider range of interfacial conditions, and also to an addition of that method to permit in some favourably configured joints the converting of the galled contacts therewithin into actual intermetallic diffusion bonds across the interlocked (joined) faces to form continuous welds. The invention proposes that, while and/or after a galled joint is formed, an electric current be passed across the joint. if the current is provided during joint formation then the supplied external mechanical energy is supplemented by the electric current energy so as selectively to heat and soften the touching asperities, enabling them to deform and flatten more rapidly to bring other smaller asperities nearby into contact and thus increase the number of gall sites. If the current is provided after joint formation, then it is believed that it results in the stimulation and/or acceleration of the formation of diffusion bonds across the opposed faces of the joint.
