Title: Method and apparatus for casting ingots of lead-alloy steel
Inventor: GRANDIN FRIEDRICH H C G
IPC: C21C7/00
Filed: 1990-04-12
Abstract: Abstract of the Disclosure A distributor for the casting of ingots of lead-alloy steel includes two parts or chambers:  the first, which receives the liquid metal directly from the ladle, referred to as the feed chamber (1), open or not open, and the second, connected to the first, closed and sealed off, of cylindrical-conical shape, is fed non-radially and referred to as discharge chamber (2).

Patent CA-2015733-A1 (CA)
IPC: E04B1/26
Filed: 1990-04-30
Abstract: ABSTRACT OF THE DISCLOSURE     An attachment system, method and connector connection for constructing a structure having supporting members and supported members as most commonly found in house and patio wood decks, board walks, stair systems, wood benches and trellis systems.  The structures using the present disclosures are characterized by the apparent absence of nails or other fasteners.  In fact, however, the structures are securely fastened by nails or screw fasteners in combination with a unique connector which uniquely is not directly connected to the supporting members.      In some forms of the invention, locator prongs are provided on the connector for assisting the installer to attach the connector to the supporting board member.  In its broadest form, however, no prongs are needed on the connector.      In a modified form of the connector, a projection is formed in the connector which bears against the underside of an adjacent structure even though the connector is not precisely installed.

Title: Self-locking nozzle blocks for steam turbines
Inventor: HALBERG WALTER
IPC: F01D9/04
Filed: 1991-01-25
Abstract: An axial flow steam turbine has a self-locking nozzle block wherein the nozzle block has radially inwardly and outwardly extending flanges that seat in grooves formed in spaced shrouds of the nozzle ring, with locking pins provided, in bores in a rear arcuate section of the nozzle ring, formed from the material that has a thermal coefficient of expansion greater than the thermal coefficient of expansion of the material from which the nozzle ring is formed. Preferably, the nozzle block is formed from a material having a thermal coefficient of expansion comparable to that of the pins. Steam passing through the turbine heats its assembly such that the locking pins force the flanges of the nozzle block into sealing contact with a first arcuate section of the nozzle ring so as to prevent vibration and loosening of the nozzle block in the nozzle ring.

Abstract: A long wavelength transmitter OEIC includes a transverse direction current injection type semiconductor laser and a high electron mobility transistor which are integrated on a semi-insulating substrate.  The semiconductor laser includes at least an AlGaInAs lower cladding layer, a quantum well active layer and a high resistivity AlGaInAs upper cladding layer successively grown on the semi-insulating substrate, disordered regions formed in the quantum well active layer by diffusions of p type and n type dopant, and an active region sandwiched by the disordered regions.  The transistor includes an operating layer and a carrier supplying layer both comprising AlGaInAs series material and formed on the high resistivity AlGaInAs upper cladding layer.  This transistor uses the upper cladding layer as a leakage current preventing layer.  This structure can be formed by only one epitaxial growth, resulting in low costs.  In addition, since the above layers are successively grown on a flat substrate, photolithography process for forming a gate of HEMT can be performed on a flat surface, so that a fine gate pattern can be formed at high precision.  As a result, a transmitter OEIC performing high speed modulation can be expected.
