Patent CA-2048559-A1 (CA)
Inventor: MAIMETS LEMBIT
IPC: B23P21/00
Filed: 1991-08-07
Abstract: P8256SOl ABSTRACT OF THE DISCLOSURE A method and apparatus for assembling an enclosure, in which the assembly includes a coil of material adapted to be uncoiled to an assembling position.   The material can be prestressed to become at least transversely curved in the uncoiled assembling position.  In a particular embodiment, the material is also prestressed to curve longitudinally, as the coil is unwound to form a toroidal shape.   Further,  the assembly can include a plurality of elements positioned within the coil, the elements having a size and shape enabling them to be adapted to be affixed to respective parts of the assembly within the enclosure in respective positions along the length of the material in the uncoiled assembling position to constitute an internal structure for the enclosure.  The plurality of elements are coiled with the coil of material for permitting access to the elements for assembling them after the material is uncoiled.  The enclosure is adapted to be used in space or terrestrially, on land or underwater, and can be appropriately sealed and pressurized.

Title: Method for isolating enzymes from enzyme-containing suspensions
Inventor: KULA MARIA-REGINA
IPC: C12M1/40
Filed: 1991-08-21
Abstract: Abstract of the Disclosure To obtain enzymes from an enzyme-containing suspension,   such  as  fermentation  broth,   the suspension  is placed,  together  with  particulate material capable of binding enzyme,  such as ion exchange  resin,  in  a  vertical  container.    An ascending stream of inert gas, such as dry nitrogen, is passed through the resulting composition at a rate sufficient for fluidization.   The resulting composition  is  mixed  and  evaporated  until  an adequate  amount  of  enzyme  is  bound  to  the particulate material.   Concentration of enzyme in the  suspension  is  directly  proportional  to  the amount of enzyme bound to particulate material. The residual suspension is forced out of the container by a pulse of compressed gas, and the bound enzyme is eluted.  To speed up the process, the stream of gas and/or the composition are heated to enzyme-tolerated temperatures.  The resulting composition can be further subjected to a washing step after removal of the residual suspension and prior to elution of the enzyme.  The washing liquid can be passed through another fixed bed column containing particulate  material  capable  of  binding  enzyme. Elution  of the  enzyme can be carried  out as a stepwise process.

Filed: 1991-08-26
Abstract: A B S T R A C T           BLOCK COPOLYMER OF POLYALKYLENE AND HALOGENATED               POLY(VINYL AROMATIC) A block copolymer is provided having the general formula S'-A-(A-S')m in which m is 1, 2, 3 or 4, A is a polyalkylene block and S' is a nuclear brominated and/or chlorinated poly(vinylaromatic) block having from 0.5 to 5 bromines and/or chlorines per aromatic ring. The polyalkylene block is substantially free of halogen. The block copolymer is prepared by polymerizing the monomers, hydrogenating the formed polymer in the presence of a hydrogenation catalyst and subsequently halogenating the hydrogenation catalyst and the hydrogenated polymer, all steps successively being carried out in the same, inert solvent.     The compositions retain the elastomeric properties of the non-halogenated form of the compounds while having significantly reduced flammability along with improved tensile strength and high temperature properties.

Title: Piezoelectric differential pressure vortex sensor
Inventor: KALINOSKI RICHARD W
IPC: G01F1/32
Filed: 1990-12-19
Abstract: A vortex sensor for measuring a flow rate of a fluid flowing through a flow passage is disclosed. The flow rate is measured by detecting alternating pressure variations generated by a shedding body placed in the flow passage. The vortex sensor includes a sensor housing having two cavities interconnected by a channel. An axle of a spool member is slideably disposed in the channel and allows each of two flange members, connected proximate each end of the axle, to shuttle back and forth with respect to the sensor housing. A piezoelectric sensing element and a biasing mechanism are disposed between the flange members and the sensor housing. The alternating pressure variations are applied to each flange member causing the spool member to shuttle back and forth. When the spool moves, mechanical forces are coupled to each sensing element by the biasing mechanisms. Circuitry, interconnected to the sensing elements, detects signals generated by the sensing elements as a result of forces applied to them.

IPC: B64D45/04
Filed: 1992-03-20
Abstract: ABSTRACT OF THE DISCLOSURE          An  aircraft  landing  system  10  is disclosed which produces  electromagnetic  guidance  signals   to  an  incoming aircraft 14 and which allow the incoming aircraft 14 to safely land  upon  the  runway  16.   This  system  10  includes  various antenna arrays 12,  18,  and 20 which are orientated so as  to provide signals in several directions.  Each of these arrays has a  separate  controller  22,  24,  and  26  having  a  separate transmitter  controller  74  uniquely  coupled  to  each  of  the antennas  80,  88.   Each  of  the  transmitter  controllers  74 separately amplifies  the  incoming  electromagnetic  energy from transmitters 52, 54.  System 10 further includes several fault monitors 92, 94, 96 which monitor the operation of system 10 and which further provide  self  test  features.   System 10 further includes voting circuitry 98, 118 to allow for continued system operation  even  upon  the  failure  of  one  or  more  of  the transmitter controllers 74 and/or the monitors 92, 94, 96 and a dual inclined travelling wave manifold 90 and 566 to provide a monitored beam output which is used by monitors 92, 94, 96 to ensure continued system operation.  Further, system 10 includes a connectorless coupling of electromagnetic energy between each of  the  transmitter  controllers  74 and  the  combiners  82,  84. This connectorless coupling allows for a more efficient energy transfer  while  obviating  the  need  for  separate  physical connections which are  inherently unreliable;  inefficient;  and costly.

Title: Surround-tec j-50 surround sound adapter
Inventor: GREENBERG GERALD L
IPC: H04S3/00
Filed: 1992-04-07
Abstract: Abstract SURROUND-TEC Version 92-01 Model J-50 will decode any standard surround sound audio on most any amplifier/receiver without noticeable compromise of sound quality. It uses a complex phase decoding network to extract the phase encoded audio signal.  It is clone right at the output of the amplifier that it is connected to.          This unit will extract the surround sound at a low cost and still give many hours of listening pleasure. When properly set up, it will greatly enhance the realism of the sound from Videos, CD's, TV, and Radio programs. This unit is a Dolby(TM) compatible system.  It uses a completely different approach to do the job.          This unit uses the principle of passive circuitry to decode surround sound material.  And, it does it with good quality results.          The separation quality and distortion of this unit is comparable to most any of the more expensive units.  It uses a new approach to obtain the surround channels.          To get the full surround benefit, please take care that the music or material selected is in surround sound. When used with standard stereo material, this surround adaptor will give the background ambience picked up by the recording studio's microphones during recording.          This adaptor uses a new system of decoding that is much simpler than the standard commercial units sold on the market.  The output quality is high in relation to the cost.
