Title: Method of forming weld bead of pure copper on ferroalloy base material
Inventor: KAWASAKI MINORU
IPC: B23K26/34
Filed: 1991-04-03
Abstract: In forming a weld bead of pure copper on a ferroalloy base material by laying a powder of copper and melting the powder by a high density energy source such as laser beams, TIG arc or electron beams, the powder of copper is beforehand mixed with a powder of an auxiliary metal having a higher melting point than pure copper. In order to ensure the substantial purity in copper of the weld bead, the powder mixture should not include more than 16 wt% nickel.
Patent CA-2042265-A1 (CA)
Title: Shaft torque measurement
Inventor: WITTE JAMES R
IPC: G01L3/10
Filed: 1991-05-09
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for determining the power output of a gas turbine engine utilizes a speed sensor coupled to the engine shaft and a signal developed by a pyrometer coupled to the engine turbine for determining engine temperature.  The speed sensor is normally provided in the engine for determining shaft speed and is part of the control system for the engine.  The pyrometer is provided also as part of the control system to monitor gas turbine temperatures.  A signal from the speed sensor derived from a toothed wheel passing adjacent the sensor is processed to obtain a train of pulse signals representative of angular rotation of the engine shaft.  The pyrometer is mounted adjacent at least one of the turbine disks of the engine for detecting instantaneous temperature of each blade of the turbine disk as it passes by the pyrometer.  The signal developed by the pyrometer is therefore a signal having peaks corresponding to passage of each blade at the pyrometer.  A signal conditioning apparatus processes the signal from the pyrometer to develop a pulse train of shaped signals corresponding to the angular position of each turbine blade as it passes by the pyrometer.  The system determines the relative phase difference between the signals developed by the speed sensor and the signals developed on the pyrometer under low load conditions and stores this information as a reference phase difference value.   Phase differences under load conditions are thereafter compared to the reference value.  The differences in phase are proportional to shaft twist and accordingly to shaft torque.

Abstract: REMOVAL OF PARTICULATE MATTER  FROM COMBUSTION GAS STREAMS             ABSTRACT OF THE DISCLOSURE        Unburned  particulate matter is removed from a combustion  gas stream by adding a conditioning agent to  modify  the resistivity of the particulate matter and  passing  the  conditioned  combustion gas stream through    an    electrostatic   precipitator   whose precipitating   elements   are   energized   with  an intermittent   applied  voltage.    The  addition  of conditioning  agent  and  the  precipitating  voltage signal   are   mutually   optimized.    A  controller receives   measurement   signals  from  sensors  that monitor  the total flow rate of particulate matter in the    gas    stream    before    the   electrostatic precipitation  treatment,  and  the  concentration of particulate  matter  in  the  gas  stream  after  the treatment.      Performance  of  the  system  may  be optimized   according  to  selected  combinations  of variables.

Abstract: ??9-90-040 SYSTEM FOR PREPARING INSTRUCTIONS FOR INSTRUCTION PARALLEL    PROCESSOR AND SYSTEM WITH MECHANISM FOR BRANCHING           IN THE MIDDLE OF A COMPOUND INSTRUCTION     ABSTRACT OF THE DISCLOSURE An instruction processor system for decoding compound instructions created from a series of base instructions of a scalar machine, the processor generating a series of compound instructions with an instruction format text having appended control bits in the instruction format text enabling the execution of the compound instruction format text in said instruction processor with a compounding facility which fetches and decodes compound instructions which can be executed as compounded and single instructions by the arithmetic and logic units of the instruction processor while preserving intact the scalar execution of the base instructions of a scalar machine which were originally in storage. The system nullifies any execution of a member instruction unit of a compound instruction upon occurrence of possible conditions, such as branch. which would affect the correctness of recording results of execution of the member instruction unit portion based upon the interrelationship of member units of the compound instruction with other instructions. The resultant series of compounded instructions generally executes in a faster manner than the original format which is preserved due to the parallel nature of the compounded instruction stream which is executed.

Abstract: Expedient fabrication of phase masks providing for many values of phase delay for exiting pattern delineating radiation depends upon a two-step procedure. Such masks offer improvement in ultimate device fabrication relative to that offered by prior binary-valued masks. In the first step, which may be carried out coincident with introduction of device feature information, apertures of appropriate size and distribution are produced in the relevant mask layer; in the second step material surrounding such apertures is heated to result in backflow-filling. Theconsequential layer thinning is such as to introduce the desired local change in phase delay.

Abstract: A novel capillary die and crystal growing method are provided for growing a hollow cristalline body by EFG. Inner and outer annular moats (114, 116) surround the die tip. Passageways (180) are provided for supplying melt (29) to those moats from a crucible (24), so that melt (29) in said moats will wet and cover the inner and outer exterior surfaces of the die tip during growth of a hollow crystalline body. The novel die may be constructed so as to have a lower die tip and a shorter capillary than EFG dies heretofore used to successfully grow hollow bodies. The die design facilitates keeping the temperature of the die tip substantially uniform about its circumference, thereby improving uniformity of thickness of the wall of the crystalline body (112) grown from a film of melt (110) on the die tip. The moats reduce the likelihood of the growth process being interrupted or adversely affected by flooding of the die. In the event the growth meniscus breaks, liquid silicon is captured in the moats, thereby preventing or reducing the likelihood of flooding of the die.
