Title: Electronically monitored angioplasty system
Inventor: NICHOLSON WARREN B
IPC: A61F2/958
Filed: 1993-06-23
Abstract: An electronically monitored angioplasty sys-tem (10) is provided with a verifier circuit (60, 72) to verify the operation of conversion circuitry (28, 28', 28") for converting an electrical pressure signal from a pressure transducer (22) to a displayed nu-merical value on a digital read-out (32). The verifier circuit is selectively activated to offset the displayed numerical value by a predetermined amount and upon deactivation the displayed numerical value re-turns to the pressure sensed by the pressure trans-ducer in the balloon (16). In one embodiment, a reference signal to the conversion circuitry is selec-tively offset by a signal corresponding to the prede-termined amount and in another embodiment the electrical pressure signal itself is selectively offset by a reference signal corresponding to the predeter-mined amount. In another aspect of the system, an audible balloon deflation indicator circuit (140) sounds a pleasant signal that the balloon is fully deflated so the doctor need not divert attention from the patient.

Patent CA-2142388-A1 (CA)
Inventor: PANETH ERIC
IPC: H04L7/04
Filed: 1995-02-13
Abstract: Analog signals representing individual digital values (+/-1, +/-3) pass through a telephone line to a receiver.      These signals may be first provided in a pseudo random sequence. A linear echo canceller and a first adder eliminate, to an extent, echo signals resulting from second analog signals transmitted on the same telephone line by the receiver. A  non-linear echo canceller and a second adder further reduce the echo signals and specifically reduce non-linear components in the echo signals. Adjustable signal delays achieve optimal performance of the linear and non-linear echo cancellers. An equalizer containing four (4) different modules then compensates for signal distortions introduced by the telephone line and minimizes the effect of noise in the telephone line.   The equalizer modules are a digital gain control element, a feed forward digital filter and two (2) feedback digital filters. A detector module produces in one of several different ways at the receiver an estimate of the digital data (+/-1, +/-3) transmitted at the other end of the telephone line. The detector either extracts the digital information based on peaks in the received (non-equalized) signal or by adding the equalized signals with preset threshold values. A scrambler-descrambler module locally generates a replica of the digital symbols transmitted in analog form at the other end of the telephone line, based on a limited number (e.g. 23) of correctly detected digital values. The scrambler-descrambler module may also operate as a descrambler to recover data scrambled by the transmitter at the other end.

Patent CA-2153897-A1 (CA)
Title: Blocking arrangement
Inventor: AUGUSTINUS PER KURT
IPC: B65D45/02
Filed: 1994-12-09
Abstract: A blocking arrangement serves for secure prevention of a spear (1) being unscrewed from a corresponding neck ring (3) in a container for a liquid, for example beer, being under pressure by a drive gas in the container. The blocking arrangement consists of a split spring ring (8) which is placed in a groove (5) constructed in the corresponding neck ring (3). This groove is so deep that the spring ring is allowed to be squeezed radially into the groove. The expansion of the spring ring radially outwards is limited, however, by an inwards turning cylinder face (22) on the spear (1). Furthermore, the spear has an upwards turning blocking face (12) which adjoins the cylinder face (22). When dismounting of the spear is attempted, its blocking face (12) adjoins the spring ring (8) which is retained axially by the downwards turning upper side (16) of the groove. To prevent the axial forces, by which the spring ring (8) is acted on, from working the spring ring free of the blocking face (12), the spring (8) has a larger thickness at the outside diameter than at the inside diameter. Thereby the blocking arrangement provides the optimal security against an unauthorized person being injured by being hit by a spear dismounted and shot out into the room by an overpressure in the container.
Patent CA-2155121-A1 (CA)
Inventor: CHRISTOPHER JAMES D
IPC: H01L29/84
Filed: 1994-01-31
Abstract: A bridging member (18) extending across a cavity (16) in a semiconductor substrate (12) (e.g. polycrystalline silicon) has successive layers - a masking layer (20), an electrically conductive layer (22) (e.g. polysilicon) and an insulating layer (24) (eg. SiO2). A first electrical contact (32) (e.g. gold coated with ruthenium) extends on the insulating layer in a direction perpendicular to the extension of the bridging members across the cavity.  A pair of bumps (34) (e.g. gold) are on the insulating layer each between the contact and one of the cavity ends. Initially the bridging member (18) and then the contact (32) and the bumps (34) are formed on the substrate and then the cavity (16) is etched in the substrate through holes in the bridging member. A pair of second electrical contacts (44) (e.g. gold coated with ruthenium) are on the surface of an insulating substrate (14) (e.g. pyrex glass) adjacent the substrate. The two substrates are bonded after the contacts are cleaned. The first contact (32) is normally separated from the second contacts (44) because the bumps(34) engage the insulating substrate surface. When a voltage is applied between an electrically conductive layer on the insulating substrate surface and the polysilicon layer, the bridging member (18) is deflected so that the first contact (33) engages the second contacts (44). Electrical leads extend on the surface of the insulating substrate from the second contacts to bonding pads disposed adjacent a second cavity in the semiconductor substrate. The resultant relays on a wafer may be separated by sawing the semiconductor and insulating substrates at the position of the second cavity in each relay to expose the pads for electrical connections.

Title: A method for separating crops and impurities
Inventor: KLINTWORTH KLAUS
IPC: B03B5/62
Filed: 1995-08-22
Abstract: A method and an apparatus for separating crops and impu-rities are described which exploit the different specific gravities of the materials to be separated. The separation is performed with the help of a liquid exploiting the different lifting forces, since the materials to be separated differ clearly in specific gravity. If the specific gravity of the separating liquid does not suffice to effect the necessary lift for the crop, one produces a flow acting against the sinking direction of the impurities to increase the lifting force for the crop and cause it to collect by floating on the surface of the separating liquid. Water is preferably util-ized as a separating liquid, and the flow produced with the help of a pump wheel or bucket wheel. The method has proven especially useful for separating potatoes and stones.
