Title: Micro-miniature radio receiver
Inventor: KNOEDL GEORGE JR
IPC: H03D7/00
Filed: 1995-05-18
Abstract: A  frequency  translated  filter  adapted  for integration  into  a  conventional  monolithic  integrated circuit arrangement.  The filter includes an RF amplifier having a gain determining port;  a one port,  AF ( audio frequency), frequency selective, gain determining immittance network; a forced-commutated bridge of bilateral switching elements interconnecting the immittance network and the gain affecting port of the amplifier, and an RF local oscillator for providing a commutating drive signal to the bridge.  The action of the RF commutating bridge is to convert the voltage and current appearing at the gain affecting port of the RF amplifier to a low frequency at the terminals of the AF immittance network, and to reflect the immittance of the AF network  back  through  the  RF commutating  bridge, translating it up again in frequency.   The effect is to permit the use of AF frequency selective elements to render an amplifier frequency selective at radio frequencies.

Title: Lifting and handling device for large cylindrical containers, e.g. water bottles
Inventor: CLOUTIER BERTRAND
IPC: A45F3/14
Filed: 1995-08-10
Abstract: A lifting and handling device comprises a flexible  elongated  strap  having  at  a  first  end thereof  a  ring  and  a  catch  and  at  a second  end thereof a pair of longitudinally aligned strips of male and female Velcro? materials disposed on the same side of the strap. The device further includes a handle having at a first end thereof a hook and being secured at a second end thereof to the strap inwardly of the male and female Velcro? strips thereof.  To secure the device to a water bottle,  the strap is brought  around  the  cylindrical  body  of  the  water bottle and the second end of the strap which carries the  Velcro?  strips  is  threaded  through  the  ring provided at the first end of the strap and is folded back such as to allow the male and female Velcro? strips to be engaged together while the strap tightly surrounds the water bottle.  To allow for the water bottle to be safely lifted and handled, the handle is then secured to the strap by engaging its hook with the strap's catch. The bottle can then be lifted by grasping the handle with one hand while the other hand is used for supporting the bottom of the water bottle.  As  the  Velcro?  attachment  is  provided inwardly of the points of attachment of the handle to the strap,  the weight of the water bottle does not apply  pressure  on  the  Velcro?  attachment  thereby preventing any unexpected and dangerous disengagement thereof.

Patent CA-2168054-A1 (CA)
Title: Spacecraft antenna pointing error correction
Inventor: CHU PETER Y
IPC: H01Q1/18
Filed: 1996-01-25
Abstract: A system and method employ a sensing of the attitude or orientation of a spacecraft for correcting the orientation of a line of sight of an instrument carried by a spacecraft to compensate for a transient perturbation in the attitude of the spacecraft.   The instrument may be a microwave antenna for communicating with a station on the earth, or a camera for viewing the earth.  The transient perturbation in the orientation, such as may be caused by the firing of a thruster  of  the  spacecraft,  is  extracted  from  a measurement of the spacecraft orientation,  such as the orientation relative to the earth.  The line of sight of the instrument is reoriented by injection of an incremental orientation  equal   and  opposite  to  the  transient perturbation.     The  application  of  the  incremental orientation can be accomplished in mechanical fashion, in the  case  of  an  antenna  mechanically  mounted  to  the spacecraft, and electrically, as in the case of a phased array antenna carried by the spacecraft.
Patent CA-2172910-A1 (CA)
Inventor: YANG JOO HWAN
IPC: A61J3/07
Filed: 1996-03-28
Abstract: An empty medicine and food capsule is disclosed,  in which the capsules are continuously and mechanically produced, and the trademark,  the content of the medicine and the like are printed on the outside of the capsule,   before filling the medicine into the capsule.  A plurality of function protuberances are formed on the annular projection of the conventional type cap at certain intervals, such that the function protuberances would protrude more deeply inwardly.   The structure of the function protuberances is simple,  and therefore,  the designing of the die is simple and can be precisely carried out.   Consequently, precise capsules can be manufactured.    Further,    the semi-locking and the final locking can be prevented during the pre-coupling,   while,  after the final coupling,   an inadvertent separation of the capsule can be prevented.   Thus the problem of the non-separation of the capsule during the filling of the medicine and the problem of the inadvertent separation of the capsule after the final coupling are solved.  Therefore,   a high quality medicine and food hard capsule is provided.

Inventor: SMITH ROGER JOHN
IPC: F02B57/08
Filed: 1995-02-15
Abstract: An  internal  combustion  rotary  engine  with  multiple cylinders and rotary crankcase supported on a pair of engine stub shafts.  The connecting rods are each connected to a different centre arranged evenly around the drive centre of a stepdrive element.  The stepdrive element which is polygonal or circular is offset from the rotational axis of the crankcase within which it revolves.  The stepdrive element drives the crankcase through a series of links.  As each piston fires the connecting rod is inclined to the piston travel axis and the angle between the connecting rod and the stepdrive element centre is close to 90 degrees.  As the piston moves through its power stroke the cylinder rotates with the crankcase maintaining the mechanically advantageous 90 degree angle for about 100 degrees of crankcase  rotation.  Symmetric  and  asymmetric  cylinder layouts, Diesel and 2-stroke layouts are disclosed.

Patent CA-2191266-A1 (CA)
Title: Catch mechanism for locks
Inventor: STANESCU DRAGOS-MICHAEL
IPC: E05B47/06
Filed: 1996-11-26
Abstract: A  door  lock  comprises   a  driver  hub connected to a door  lever,  a driven hub,  a latch lever movable by the driven hub for retracting the lock's bolt to open the lock, and a catch mechanism for  selectively  connecting  the  driver  hub  to  the driven hub.   The catch mechanism includes  an idle position in which the driver hub moves without moving the driven hub and an engaged position in which the driver hub moves the driven hub and thus the lever and  the  bolt.    A  state  selection  mechanism  is provided to displace the catch mechanism between its idle and engaged positions.  An actuating mechanism, e.g.  a  solenoid,  selectively  positions  the  state selection mechanism such that the latter causes the catch mechanism,  when driven by the driver hub,  to adopt one of its idle and engaged positions such that the catch mechanism respectively drives, or not, the driven hub.  The actuating mechanism thus allows the state selection mechanism to mechanically cause the catch mechanism to selectively connect or disconnect the  driver  hub  from  the  driven  hub  and  thus to respectively unlock or maintain locked the door lock. The actuating mechanism typically allows  the  state selection mechanism to position the catch mechanism in its engaged position,  i.e. in its door unlocking position, when activated by a current which results from  a  valid  entry  having  been  recorded  in  an electronic access control system, or the like.
