Patent CA-2001019-A1 (CA)
Inventor: DETTRO GREGORY J
IPC: H01J3/14
Filed: 1989-10-19
Abstract: A method is provided for isolating and processing certain information-of-interest received by a receiver in a Time Division Multiple Access (TDMA) communications system having a receiver and a transmitter. The information-of-interest is transmitted at predetermined intervals. The receiver receives a transmission of signals containing the information-of-interest transmitted from the transmitter. The start of the transmission is sensed from the received signals. The receiver isolates signals received after a predetermined period elapses after the start of the transmission is sensed so as to include the information-of-interest in the isolated signals. Then, the isolated signals including the information-of-interest are processed. In the preferred embodiment, the receiver automatically controls the gain of an amplifier amplifying the received signals in response to the signal power of the received signals. Automatic gain control values of the amplifier are sampled for a predetermined period after the start of the transmission is sensed. A fixed automatic gain control value is determined in response to the sampled automatic gain control values, and the receiver holes the automatic gain control value at the fixed value after the predetermined period elapses until the transmission ofthe information-of-interest ends. Furthermore, the receiver digitizes the received signals, and tags the digitized signals which were digitized from signals received before the start of the transmission is sensed to ignore the tagged signals in processing the information-of-interest.

Title: Method of heat-treating unstable ceramics by microwave heating and susceptors used therefor
Inventor: APTE PRASAD S
IPC: C04B35/645
Filed: 1989-10-19
Abstract: Abstract:     A method of sintering thermally unstable (usually non-oxide) ceramics by microwave heating.  In the method, a body of the ceramic is at least partially surrounded with a protective bed of particulate material and then the body and the bed are subjected to microwave irradiation to cause heating and sintering of the body.  In order to allow the method to be carried out in an oxygen-containing gas such as air and at low pressure, the bed contains effective amounts of:  (a) a microwave susceptor, if the unstable ceramic is not already a susceptor, (b) a protective material capable of generating a localized atmosphere which reduces decomposition and/or oxidation of the unstable ceramic, (c) an oxygen getter and (d) a material of sufficiently good thermal conductivity to prevent excessive localized heating in the bed.  The invention also relates to the bed of particulate material used in the method and to a process for joining bodies of unstable ceramics by microwave irradiation using the protective bed.

Title: Vscf starter/generator systems
Inventor: BAKER DONAL E
IPC: H02P1/52
Filed: 1989-12-19
Abstract: ABSTRACT OF THE DISCLOSURE A  variable  speed,  constant  frequency starter generator  system   is  provided   with  a  dynamoelectric machine, electrically connected  to  a  multiple-phase bus and pair  of multiple-phase   rectifiers for producing a DC voltage  on  a  pair  of  link  conductors.    An inverter converts the  DC voltage  to floating  AC voltage which is further converted to a  ground-referenced AC  voltage by a transformer.    During  generator  operation,  the  output voltage of the machine is rectified by at least one of the rectifiers to  produce a DC voltage on the link conductors which is converted to a constant  frequency AC  voltage by the  inverter.    During  starter operation, an externally supplied AC voltage is  applied to  the transformer.   The transformer converts  the externally applied AC voltage to a pair of phase-displaced AC voltages  which are rectified by  rectifiers   to  produce twelve-pulse  rectified  DC voltage on the link conductors.  This reduces the harmonic content  of  the  current  supplied  by the external power source.

Filed: 1990-03-07
Abstract: MOLTEN METAL PUMP                          Abstract A molten metal pump (10) includes an impeller (40) disposed at the end of an elongate drive shaft (30).  The drive shaft (30) is disposed within an elongate, hollow post (28).  The impeller (40) and the end of the post (28) are adapted to be immersed in molten metal.  An inert gas is conveyed through the gap between the outer surface of the drive shaft (30) and the inner surface of the post (28), which gas is discharged into the molten metal in the vicinity of the impeller (40).  Because the drive shaft (30) is insulated from the molten metal,  it can be made of a durable material  such as steel;  because the post  (28)  is stationary relative to the molten metal, the metal is stirred only by the impeller (40), and not by the drive shaft (30).  The invention includes other features such as a quick disconnect capability and a radial adjustment capability.

Title: Method and apparatus for fabricating microlenses on optical fibers
Inventor: PRESBY HERMAN M
IPC: G02B6/255
Filed: 1990-03-21
Abstract: This invention concerns with a process and apparatus for fabricating microlenses on optical fibers. A pulsed laser beam and an end portion of a fiber are arranged relative each to another so that the laser beam is incident on the end portion of the fiber at an acute angle .theta. to the longitudinal axis of the fiber. The angle is selected to attain a desired curvature of a lens formed by ablation and heating of the end portion of the fiber by the laser beam. A movement of the fiber and the laser relative each to another results in progressive engagement of the end portion of the fiber with the laser for a preselected distance so as to produce a short taper with a lens at the end thereof. In the preferred embodiment, the fiber rotated about its axis within a passage of the holder which moves the end-portion of the fiber into and through the laser beam resulting in the said lens. The precise repeatability of the lens formation may be controlled by a computer.

Abstract: RANDOM-ACCESS DIGITALLY-TUNED COHERENT OPTICAL RECEIVER Abstract A selectively tunable coherent optical receiver includes a tunable laser for producing a selectable local oscillator frequency for receiving any one of a group of received optical channel signals. The tunable laser is controlled by a feedback loop and a digital processor that stores values of laser bias current. The arrangement produces an exact local oscillator frequency for operating with any one of the group of selectable received channel signals which are spaced over a range of optical carrier frequencies. This receiver avoids frequency sticking and very long pull-in time and determines when there is a missing channel or missing channels.

Abstract: EQUIPMENT RACK Abstract An equipment rack is disclosed whose frame member arms include protrusions, or a protrusion and a flange, that serve a dual function. First, the protrusions, or protrusion and flange, serve to define channels suitable for receiving a cable restraint device which serves to separately bundle cables according to type and/or function. Second, the protrusions serve as keyways along which additional, movable frame members slide telescopically to achieve a rack extendible to a wide variety of heights. Preferably, the inventive rack is of aluminum, resulting in a rack that is essentially as sturdy as the conventional steel racks but significantly lighter and easier to install.

Abstract: Abstract of the Disclosure A peptide amidase isolated from the flavedo of  citrus  fruits,  preferably  oranges,  which  is capable  of  catalyzing  the  selective  hydrolytic elimination  of  the  free  amino group  on the  C-terminal end of peptide amides but which does not cleave peptide bonds.  The enzyme accepts D-amino acid residues in the C-terminal position, although the hydrolysis rate is much slower than with L-amino acid residues.  The enzyme is weakly inhibited by serine protease inhibitors; has an optimal pH of 7.5 + 1.5, an optimum temperature of 30°C at pH 7.5 and has an isoelectric point of pH 9.5.   The peptide amidase is stable at pH 6.0-9Ø   The molecular weight of the purified enzyme is 32,000 +/- 3000 daltons.  A peptide amidase according to the present invention is particularly useful in the production of peptides by continuous enzymatic reaction of N-protected amino acid or peptide alkyl esters with amides of amino acids.  In the continuous reaction, the synthesized peptide amide is hydrolyzed by the peptide amidase and separated by anion exchange from the amide of the amino acid which can be recycled.
