Title: Cryogenic gas purification process and apparatus
Inventor: EYRE DOUGLAS V
IPC: F25J3/08
Filed: 1989-11-27
Abstract: ABSTRACT OF THE INVENTION       A process and apparatus for the ultrapurification of cryogenic low boiling liquified gases such as oxygen and nitrogen which contain trace impurities.  The impure gas is introduced into a first distillation column and is substantially at its liquid-gas equilibrium temperature at the pressure within the first distillation column.  Here the gas is separated by distillation into first vapor fraction containing low boiling point impurities and a first liquid  fraction containing high boiling point impurities.  The first vapor fraction is withdrawn and introduced into a second distillation column.  The first vapor fraction is substantially at the liquid-gas equilibrium temperature at the pressures within the second distillation column. Here the vapor fraction is separated by distillation into a second vapor fraction containing high boiling point impurities and a second vapor fraction free of trace impurities which is withdrawn as product. Cooling the process is provided by indirect heat exchange with a cryogenic low boiling gas such as nitrogen, oxygen, or air.  The gas to be purified as well as the heat exchange gas can be obtained from a standard air separation unit or the process can be conducted using gases obtained from storage.

Patent CA-2011408-A1 (CA)
IPC: B07B7/083
Filed: 1990-03-02
Abstract: Abstract of the Disclosure The known pulverized coal combustion method including the steps of separating pulverized coal mixture gas ejected from a vertical type coal grinder containing a rotary type classifier therein into thick mixture gas and thin mixture gas by means of a distributor, and in-jecting these thick and thin mixture gases respectively through separate burner injecting ports into a same furnace to make them burn, is improved so as to reduce both an unburnt fuel content in ash and a nitrogen oxide concentration in exhaust gas while maintaining excellent ignition characteristic.  The improvements reside in that an air-to-fuel ratio of the thick mixture gas is chosen at 1 - 2, while an air-to-fuel ratio of the thin mixture gas is chosen at 3 - 6, and the range of a degree of pulverization of the pulverized coal is regulated at 100 mesh residue 1.5% or less.  The degree of pulverization of the pulverized coal fed to the distributor is regulated either by adjusting a rotational speed of the rotary type classifier or by adjusting the angles formed between classifying vanes rotating about the axis of the rotary type classifier and the direction of rotation.

Title: Continuously-operating press
Inventor: BIELFELDT FRIEDRICH B
IPC: B30B5/06
Filed: 1990-06-06
Abstract: The present invention relates to a continuously-operating, press suitable for producing compressed flat products from suitable material.  The press comprises flexible endless metal bands, separated by an adjustable press gap, serving to transmit pressing force to the material and to pull the material through the press gap, the bands being directed by means of drive rollers and deflection rollers about a press bed and a press top and supported via roller rods running in the same direction as said bands against the press bed and the press top. The axes of the roller rods are oriented transversely relative to the direction of movement of the bands, and the roller rods are fed orthogonally relative to the longitudinal median of the press into the press gap by means of roller chains and by means of feed devices located in the entry zone of the press gap.  A flexible clamping device is arranged in the entry zone which exerts continually increasing pressure upon the roller rods as the rods enter the press gap. In this way, the rods can be kept in their proper orientation by frictional means without relying solely on the roller chains.  Rapid wear of the roller chains and other elements can thereby be avoided.

Inventor: VOEGELI OTTO
IPC: H01S5/185
Filed: 1991-02-25
Abstract: A semiconductor device, formed on a wafer (13), comprises an array of laser diodes (Q1,Q2), each emitting a beam (B1,B2) parallel to the wafer surface, and, integrated with the array, individually tilted deflecting mirrors (R1,R2) forming an array of virtual sources (Q1',Q2'). Compared to the physical separation of the laser diodes, the virtual sources are spaced more closely, they can even be coincident, thereby reducing the apparent spacing between the beam origins. The reflected beams (B1',B2') are substantially perpendicular to the wafer providing a "surface-emitting" device.   The required deflector configuration (54) can be fabricated in a single unidirectional process, the mirror positions and orientations being determined by proper segment geometry of the etch-mask.

Title: Electronic circuit for generating error detection codes for digital signals
Inventor: GANDINI MARCO
IPC: H03M13/15
Filed: 1991-02-27
Abstract: An electronic circuit, for generating error detection codes from digital signals organized into serial data blocks, in which the error code is derived from the coefficients of a remainder polynomial obtained from the division by a suitable divisor polynomial of a dividend polynomial whose coefficients are the bits of each serial block, is implemented by feedback through adders within shift register.  A reset of the register necessary at the beginning of each serial data block and the loading of a first data bit of the block are both performed in a single clock interval, by using flip-flops to form the register which have alternative inputs one of which is used during reception of the first bit of a block to handle that bit and place the remainder of the register in a defined condition, and the other of which is used during processing of the remaining bits.
