Patent CA-2076712-A1 (CA)
Inventor: BRENTON RONALD G
IPC: H01H35/18
Filed: 1992-08-24
Abstract: Apparatus for indicating the level of flowable material in a storage bin that includes a motor mounted within a protective enclosure and coupled by a shaft and clutch arrangement to a paddle disposed within the bin to engage material therewithin.  When the material reaches the level of the paddle, drag on the paddle causes the motor to rotate within the enclosure against the force of an adjustable spring to activate switches disposed within the enclosure for indicating material level.  The switches also remove power from the motor and apply power to an electrical resistance heater to warm the enclosure and help prevent condensation at low external ambient temperature.  The paddle is constructed to enhance drag when used in conjunction with low-density materials.

Title: Recombinant fowlpox virus
Inventor: DORNER FRIEDRICH
IPC: A61K39/00
Filed: 1992-08-26
Abstract: Abstract An improved method is described to prepare recombinant fowlpox virus for the expression of proteins or for use as a vaccine. The new method uses for the insertion of foreign DNA an intergenic region which is located between the FPV thymidine kinase (tk)gene and the 3'-open reading frame. Said intergenic region is enlarged to comprise one or more unique restriction sites, thereby allowing insertion of foreign DNA in such a way that the FPV tk-gene remains intact and codes for the entire thymidine kinase.            New strong poxvirus promoters are presented and new FPV host virus strains carrying a vaccinia virus thymidine kinase gene and an E. coli lacZ gene as a novel non-essential site. The novel fowlpox virus host strains allow the use of any insertion plasmid carrying vaccinia virus tk-gene flanking regions.
Patent CA-2080542-A1 (CA)
Inventor: KOENIG LARRY E
IPC: F16M7/00
Filed: 1992-10-14
Abstract: Docket No. K1515-012 Abstract of the Disclosure A rotary motor with a counterbalanced torque arm adapted to be mounted within an auger housing.  The torque arm is mounted on the stationary cylinder block of the motor which extends readily outwardly from the access of the cowling and is attached to the auger housing.  The torque arm includes a pair of diametrically opposed torque arm members which support pairs of cylinders.  The cylinders engage the housing and are interconnected such that diametrically opposed pairs of cylinders are in fluid communication.  Accordingly, rotational torques exerted on the torque arm by the cylinder block, for auger screw rotation both in the clockwise and counterclockwise directions, are born equally by the opposing torque arm members.

Title: Automatic derailleur shifter
Inventor: MCLAREN MICHAEL J
IPC: B62M9/12
Filed: 1991-06-10
Abstract: An automatic derailleur shifter system for example for a bicycle includes a hub (11) to which is attached a chain wheel (16) set and a derailleur system for moving the chain associated therewith from chain wheel to chain wheel for a gear changing system.  Within the hub associated with the chain wheels is provided an automatic changing system including a member coupled to the chain wheel set which carries a helical screw (47) cooperating with the screw so that rotation of the screw relative to the sleeve (34) causes the sleeve to move axially. Axial movement of the sleeve is inhibited by a spring (78) and rotational movement of the sleeve is prevented by engagement with the hub. Thus variations in the torque applied from the chain set to the hub through the screw in the sleeve cause axial movement of the sleeve which actuates change of the gears by moving to the derailleur set. The spring can be internal to the hub or can be provided outside of the hub. In addition movement of the sleeve can cause rotational movement of a second screw member (60, 70) at an opposed end of the hub which can be used to change a front chain wheel set at the pedals.
Patent CA-2086174-A1 (CA)
Inventor: SUNDARARAJAN DURAISAMY
IPC: G06F17/14
Filed: 1992-12-23
Abstract: Since the invention of the radix-2 structure for the computation of the discrete Fourier transform (DFT) by Cooley and Tukey in 1965, the DFT has been widely used for the frequency-domain analysis and design of signals and systems in communications, digital signal processing, and in other areas of science and engineering. While the Cooley-Tukey structure is simpler, regular, and efficient, it has some drawbacks such as more complex multiplications than required by higher-radix structures, and the overhead operations of bit-reversal and data-swapping. The present invention provides a large family of radix-2 structures for the computation of the DFT of a discrete signal of N samples. A member of this set of structures is characterized by two parameters, u and v, where u (u = 2r, r = 1, 2, . . ., (log2 N)-1) specifies the size of each data vector applied at the two input nodes of a butterfly and v represents the number of consecutive stages of the structure whose multiplication operations are merged partially or fully. It is shown that the nature of the problem of computing the DFT is such that the sub-family of the structures with u = 2 suits best for achieving its solution. These structures have the features that eliminate or reduce the drawbacks of the Cooley-Tukey structure while retaining its simplicity and regularity. A comprehensive description of the two most useful structures from this sub-family along with their hardware implementations is presented.

Title: Technique for demodulating and decoding mls dpsk transmissions using a digital signal processor
Inventor: LABERGE EDWARD FRANCOIS CHARLE
IPC: H04L27/233
Filed: 1991-05-09
Abstract: A system for demodulating and decoding differential phase shift keying (DPSK) transmissions utilizes a bandpass filter (11), an analog to digital converter (12) and a digital signal processor (13). Removal of the effects of unknown frequency component is achieved by applying a complex phase correction/rotation factor after DPSK demodulation. The actual phase of the complex signal is never computed directly. All of the processing from Rader decomposition (14) through carrier tracking filter is performed on the complex values and therefore requires only multiplication and addition operations which can be performed at high speed in a microcomputer or in dedicated arithmetic hardware.

IPC: G06F12/08
Filed: 1993-01-05
Abstract: Apparatus  and  method  insuring  that  data  objects used to maintain state information for  shared data at a local  central  processing complex  (CPC)  is  coherent with respect  to  state  information maintained  at  a  structured external  storage  facility  (SES)  over  a  link  is  valid. An  error  detector  is  attached  to  the  CPC  side  of  the link  for  detecting  errors  on  the  link,  and,  when  an error  is  detected,  setting  a  error  state  pending  (ESP) latch to indicate that the link has failed and that the shared  data  in  the  local  data  object  may  be  invalid because  a  message  invalidating  the  data  may  not  have been   received   by   the   CPC.    In   data   processing operations,  the  ESP  latch  is  interrogated by  a  central processor  in  the  CPC  to  determine  the  health  of  the message path to the SES facility.   A local cache vector reflecting the validity of the  shared data in the  local cache  may  then  be  interrogated  to  determine  if  the shared data in the  local  cache  is valid.   If a healthy path  has  continuously  existed  and  the  vector  indicates that  the  local  cache  data  is  valid,  the  integrity  of the data can be relied on.
