Patent CA-2010851-A1 (CA)
IPC: F23N5/20
Filed: 1990-02-23
Abstract: ABSTRACT OF THE DISCLOSURE         In space heaters with pressure atomization burners, which have a small  combustion chamber volume, good mixing of air with fuel is achieved  practically only in the case of relatively high air flow velocities, which  leads, however, to difficulties in terms of ignition, especially at high  operating voltages and low temperatures.  The blower motor is therefore  started first when putting the heater into operation, after which it is  disconnected from the power source, so that the speed will again decrease, after which the high-voltage ignition and the fuel supply are turned on, so  that the ignition can take place at reduced blower speed, and the high-voltage  ignition is turned off and the blower motor is restarted after the flame has  been recognized in the burner.

Title: Process for producing alkyl tertiary-alkyl ethers and c5+gasoline boiling range hydrocarbon
Inventor: HARANDI MOHSEN N
IPC: C10G3/00
Filed: 1990-07-27
Abstract: ABSTRACT        An integrated process is disclosed that substantially reduces the cost of producing MTBE  and other alkyl tert-alkyl ethers by eliminating a major portion of the equipment and operating costs associated with the downstream processing of the etherification reactor effluent.  The integrated process combines the process for the etherification of iso-olefins and methanol, or other alkanols, to produce methyl tertiary alkyl ethers such as MTBE and/or TAME with the catalytic process for converting feedstock such as oxygenates, light olefins and paraffins to higher molecular as weight hydrocarbons. Unconverted reactants from the etherification reaction, which may comprise unreacted alkanol and unreacted hydrocarbons or just unreacted hydrocarbons, are separated from the product ethers and passed to the catalytic conversion process reactor for conversion to gasoline boiling range hydrocarbons.

Title: Fast packet and frequency switch
Inventor: DANIELE ANTONELLA
IPC: H04B10/291
Filed: 1990-08-01
Abstract: A fast packet and frequency switch has inputs and outputs connected to optical fibres, each accommodating a number of different wavelength optical carriers, modulated by serial information flows organized into packets.  These packets are phase-realigned and their labels are converted by an input block under control of external processors designed to set up and tear down connections.  The optical carriers allocated to packets are frequency converted, and the packets are recombined onto a single fibre by a passive recombination network for storage in an optical loop memory formed by  an  optical  fibre  delay  line.   Packets  are extracted as their assigned outputs and output carrier frequencies become available, and the combined packets are again frequency converted using converters driven so that frequencies not corresponding to the assigned outputs and output carriers are discarded.  The remaining packets are recombined at the outputs.

Abstract: A B S T R A C T A corrective positioning method in a robot, capable of eliminating degraded positioning accuracy attributable to inherent errors in the robot.     By using displayed rotary angles of first and second links (1, 2) determined by a mastering sequence associated with known points, a simultaneous equation including, as unknowns, link length errors (.DELTA.11, .DELTA.12) and actual rotary angles (.theta.1, .theta.2) of the links is solved, to thereby determine the link length errors, errors (.DELTA.xO, .DELTA.yO) of a pivotal center position of an arm, and errors (.DELTA..theta.10, .DELTA..theta.20) of rotary angles of the links.  During a robot operation, X-axis and Y-axis target moving positions of a distal end of the arm, which are specified by a program, are corrected by using the pivotal center position error, and the actual link lengths are calculated by using the link length errors, and further rotary angles of servomotors respectively associated with the first and second links are determined by a coordinate conversion process performed on the basis of the corrected moving positions, the actual link lengths and the link rotary angle errors.

Title: Method and apparatus for on-line processing of transaction data
Inventor: WATAYA HIROSHI
IPC: G06F17/30
Filed: 1990-09-19
Abstract: Transaction data are generated at one or more terminal units and are transmitted to a transaction management system which stacks such data until predetermined conditions occur. When the predetermined conditions occur the stacked transaction data are transmitted as a batch for processing. Confirmation of successful processing is then re-transmitted to the terminal units. The predetermined conditions for batch transfer may be expressed in terms of a maximum number of stacked transaction data or a maximum time of stacking or both. By transferring transaction data for processing as a batch, the processing time can be reduced. As with standard transaction processing, it is important that processing operates in an all-or-nothing way and so appropriate storage is provided of the transaction data and the record or records being changed to ensure that the original record may be restored if there is a failure of any part of the transaction processing. The method may be applied to a banking or lottery system.

IPC: B04C5/13
Filed: 1990-09-20
Abstract: For the separation of at least one material from a liquid or gaseous medium, with a specific gravity different from the medium, the flowing mixture of material and medium is set into rotation about an axis oriented in parallel to its flow-off direction, the material is separated from the medium by centrifugal forces, and discharged separately from the purified medium. The velocity of the rotation of the mixture of material and medium is increased by an increasing reduction of the radius of the rotary movement. The medium is discharged from the device by means of mutually coaxially opposed dip pipes. An apparatus (10) for performing the process comprises a baffle (112) for producing the rotary motion of the introduced mixture in a separating chamber (113).      The purified medium is withdrawn from the separating chamber (113) by way of mutually opposed dip pipes (114, 115), the cross section of which is smaller than that of the separating chamber (113). The separated material is discharged by way of a secondary cyclone (118) and a pipe (120).

Each of the strands is formed  from a material having substantially fifty five percent (55%) titanium and forty five percent (45%) nickel by weight.  The strands have the properties of being formed to any desired configuration in and arched relationship at a temperature below a particular temperature such as 10°C - 15°C. and of returning to the desired configuration when bent from the desired configuration to the desired configuration when bent from the temperature.  The multi-strand configuration is then bent from the desired configuration at a temperature above the particular temperature to conform to the actual configuration of the teeth in the patient's mouth and is attached to the patient's teeth in this bent configuration.  The multi-strand filament returns to the desired configuration while attached to the patient's teeth, thereby causing the position of the teeth in the patient's mouth to become disposed in the desired configuration.  In another embodiment, the multi-strand braid envelopes a centrally disposed wire.  The centrally disposed wire may be made from the same material as, or a different material than, the braids, depending upon the characteristics desired.
