Patent CA-2172789-A1 (CA)
Title: Wall Anchor Accommodating Fasteners of Varying Thread Diameters
Inventor: MCELDERRY JAMES W
IPC: F16B25/10
Filed: 1996-03-27
Abstract: A wall anchor uses splines on an interior surface of a  cylindrical  body  to  accommodate  fasteners  having different thread diameters.  The splines are configured in types.    A  first  type  includes  at  least  one  spline protruding centrally at a narrow angle, while a second type also includes at least one spline protruding centrally at a wider angle.  When a fastener, such as a #6 or #8 sheet metal screw (SMS), is inserted into the wall anchor, the first type of spline will primarily engage the #6 SMS, while  the  second  type  of splines  are  only  partially implemented.   When a #8 SMS, which has a larger thread diameter than a #6 SMS, is inserted into the wall anchor, both the first and second types of splines are engaged to facilitate retention of the SMS.
Patent CA-2173692-A1 (CA)
Title: Back jet flush toilet systems and methods
Inventor: JOHNSON DWIGHT N
IPC: E03D11/08
Filed: 1996-04-09
Abstract: A flush toilet system includes a bowl that is drained in a flush operation through a flow path including a trap and a siphon.  A bypass passage supplies a back jet of water in the reverse flow direction in the flow path.  A back jet valve assembly opens to permit back jet flow during only the first part of the interval during which flush water is supplied to the system from a water supply.  The kinetic energy of the back jet is converted to static pressure to block or impede flow of flush water through the flow path.  Water level increases in the bowl, and when the back jet flow is discontinued a siphon flush operation proceeds.  The back flush valve assembly also releases water after the flushing operation in order to reseal the trap.

Title: Retail theft prevention and information device
Inventor: ROBINSON DONALD G
IPC: G08B13/24
Filed: 1994-09-30
Abstract: A device (10) and system for automatic identification of the item and for preventing the theft of the item. The device comprises a frequency activation circuit (22), a power source (28), a switch (48), a memory device (30) and transmitter circuitry (32, 22). The memory device stores a code identifying the product. The frequency activation circuitry receives an external frequency signal and generates an activation signal to couple power to the memory and thereby cause the memory to output the code. The transmitter receives the code and converts it into a frequency modulated signal. The device may also be secured to an item for the purpose of preventing theft of the item. In such a case a frequency reader activates a deactivating device to disable the frequency transmitter after reading the code. An alarm is located next to the exit of the building to activate an alarm if a frequency code is received indicating the presence of an item with an active device.

Title: Retransmission control method of cdma mobile communication
Inventor: ZHAO HUI
IPC: H04W28/04
Filed: 1996-10-22
Abstract: In CDMA mobile communication of the packet switching mode which is one-way, the packet is transmitted to divide to a frame unit. In this time, the first, the second and the third transmission timing which are obtained to divide to three pieces the predetermined frame are set up for increasing the transmission efficiency by realizing the retransmission of the frame unit, as the transmission timing of a backward control signal in a backward channel, Base station 100 transmits a forward signal (a forward control signal and an user data signal) by using code A (a forward channel) at any frame. When the forward signal is received at this frame by mobile station 70, mobile station 70 transmits a receiving acknowledgment signal (a backward control signal) of the forward signal by using code A' at the first transmission timing of the next frame. Conversely, when the forward signal is not received correctly, mobile station 70 transmits a retransmission request signal (the backward control signal) of the forward signal by using code A' at the first transmission timing of the next frame. The similar operation carries out in mobile stations 80 and 90. However, in this case, the transmission timing of the backward channel is the second or the third timing.
