Patent CA-2158031-A1 (CA)
Title: Anti-theft device for bottles
Inventor: HOLMGREN BERTIL
IPC: B65D51/24
Filed: 1994-03-11
Abstract: The invention relates to an anti-shop-lifting device, intended to be passed onto and locked to a bottle-neck  having an external circumferential bead. The device comprises an outer socket (15) which can be shifted in relation to an inner socket (10) between two end positions and is locked by latch means (24) in one end position. A number of retainers (21) distributed  peripherally on the inner surface of the outer socket, when the outer socket is in said one end position extend into the inner socket through openings (13) in the wall of said inner socket to an engaged position in which the retainers engage behind the bead on the bottle-neck in order to prevent the anti-shop-lifting device from being withdrawn.  The latch means (24) is biased to latching position but can be actuated by means of an external element (13) to a disengaged  position against the bias in order to allow movement of the retainers from the engaged position and thus withdrawal of the anti-shop-lifting device from the bottle-neck.

Title: Method and apparatus for detecting faults in buried conductors
Inventor: LULHAM DON A
IPC: G01R31/08
Filed: 1995-09-22
Abstract: The present invention relates to an apparatus for detecting faults in buried conductors comprising a transmitter means adapted to transmit electro-magnetic signals down the buried conductor; this signal is provided to increase an electro-magnetic path or corridor existing at the surface above the buried conductor. The present invention also relates to a detecting means adapted to detect the electro-magnetic path or corridor, and to detect electro-magnetic patches formed in the path or corridor. These patches are located over the faults, and they are characterized by presence of an increased level of electro-magnetic energy caused by the faults. The transmitter means are adapted to transmit a composite signal comprising a carrier signal transmitted by a carrier signal means and a low frequency signal transmitted by a low frequency means. The carrier signal means comprise an RF carrier signal means and an audio tone signal means; the audio tone signal means are adapted to modulate signals transmitted by the RF carrier signal means. The low frequency signal means are adapted to modulate signals transmitted by the carrier signal means, and the low frequency signal is provided to increase the level of electro-magnetic energy present at faults of the buried conductor. The carrier signal means are adapted to operate in a trace mode provided to locate the position of the buried conductor under the ground, and this trace mode is characterized by a continuous signal transmitted by the carrier signal means.

Patent CA-2161170-A1 (CA)
Title: Battery feed circuit
Inventor: SCHORR IAN ANDREW
IPC: H04M19/00
Filed: 1995-10-24
Abstract: Resistive circuits are provided at the tip and ring of the battery feed circuit as a method of alleviating the need for bulky DC transformers or complex integratedcircuitry. The voltage is monitored through a set of comparators eliminating theexpense of maintaining fused resistors. The voltages for voice or data transmission is amplified prior to being transmitted. Received signals are AC coupled, with proper biasing, onto the tip and ring lines. Any AC noise on the tip and ring line is shifted 180 degrees out of phase and re-inserted on the line to cancel the noise. As an enhancement to the battery feed circuit, another voltage comparator is added to check the line for DC current signifying an off hook condition.
