Title: Balanced mixer circuit
Inventor: KOSUGA TADASHI
IPC: H03D7/14
Filed: 1990-06-14
Abstract: An RF tank circuit includes a coil L1 with a centre tap C1, it receives an input RF signal ei, and provides a balanced mixer circuit either receiving a local signal through second C8 and third C9 capacitors at first and second coil ends, respectively, with the centre tap grounded, or receiving a local signal at the centre tap (Fig 3). An impedance L5, L6 is connected between the first and second coil ends of the RF tank circuit, the impedance providing low impedance for an intermediate frequency signal, and high impedance for a high frequency signal and a local signal. A bias resistor R2 is connected between a middle connecting point of the impedance and ground. The coil of the RF tank circuit can be one of a primary (L7, Fig 2) and secondary winding L1 of an isolation transformer, with a remaining one of the primary and secondary windings being connected to an RF signal source ei, the isolation transformer preventing the leakage of a local signal to the RF signal source. The balanced mixer circuit does not require a hybrid transformer. <IMAGE>

Title: Fine-tuning of a transversal equalizer
Inventor: KARI RISTO
IPC: H04L25/03
Filed: 1990-08-15
Abstract: The invention relates to a method for the fine-tuning of a transversal equalizer used in the receiver of a data communication system by means of a short, non-periodic signal sequence contained in the received signal immediately after the determination of the initial values of the equalizer coefficients on the basis of a received training sequence.

Title: Safety-control for vehicle window
Inventor: HELLER NORBERT
IPC: E05F15/00
Filed: 1994-10-14
Abstract: A window glass in a motor vehicle body is slidable in a vertical direction within a window frame by means of an electric motor (34) controlled by "up" and "down" switches (36, 40). The window glass slides with reference to a window guide channel (11 which incorporates a metal carrier, or other electrical conductor, (14) which receives the output from electrical oscillating means (28). If a part of the human body is present within the frame of the window and within a predetermined distance from the window guide channel (11), the resultant capacitive effect will change the output of the oscillator (28) which is detected by a detecting unit (42) and opens a switch (38). This switch (38) is connected in series with the "up" switch (36) for the window drive motor (34) and thus either stops the motor, if it is driving the window glass upwards, or prevents the window glass from being so driven.

Title: Male incontinence sheath and applicator
Inventor: MILLS BARRIE THOMAS
IPC: A61F6/00
Filed: 1994-11-29
Abstract: An applicator for a condom-like urinary sheath comprises a first tubular sleeve 44 which can telescope inside a second tubular sleeve 46. In use, the urinary sheath is fitted onto the end of sleeve 44 and sleeve 46 is then withdrawn in the direction of arrow A. This causes a reduction of pressure within the space between the two sleeves causing the sheath to extend. The device is then placed over the penis and the closure member 46C removed to allow ambient atmosphere to enter the space. This allows the sheath to contract under its own elasticity and to collapse around the penis, with the adhesive layer 42B contacting the penis to hold the sheath securely. Alternatively, the two telescoping sleeves may be replaced by a bellows which upon expansion produces the required reduction in pressure to expand a sheath fitted over the end thereof. <IMAGE>
