Patent CA-2027387-A1 (CA)
IPC: H04L27/233
Filed: 1990-10-11
Abstract: Abstract of the Disclosure The present invention covers the notion of determining signal dispersion characteristics, such as amplitude, phase and delay, by transmitting training sequences. More specifically, each sequence comprises a plurality of predetermined symbols and is transmitted two or more times. Detection of each training sequence is provided by a correlator at the receiver. This detection creates a signal peak for each training sequence at the output of the correlator. Between the peaks, a "quiet zone" is created which permits signal dispersion in this zone to be characterized with respect to amplitude, phase and delay. Two different quiet zones are utilized toresolve ambiguities which arise in determining the aforesaid signal dispersion characteristics.

Title: Rotary opposed piston internal combustion engine
Inventor: HORSLEY PETER B
IPC: F02B57/00
Filed: 1990-11-13
Abstract: ABSTRACT   In my invention of a rotary engine the displacement is accomplished with ordinary pistons and cylinders, and by this means the problems of blow-by and oil-drift in lobe-type and sliding vane type rotary engines are avoided. In my engine two sets of pistons are opposed and they are adapted to reciprocate in two opposed groups of cylinder chambers spaced around the circumference of two rotary members all parallel to the axis of rotation. The two circular groups of cylinders are rotated on an angle with respect to each other, and the angle acts to make the fixed piston sets reciprocate within the cylinders. The main advantage of this arrangement is that the usual valve-shafts, crank-shafts, connecting rods and the related bearings are all eliminated. The four stroke cycle is accomplished during one revolution of the engine by using a high-pressure fuel injection jet between two sets of pistons, and the valve action is accomplished by using cones with ports at suitable intervals. Two rows of cylinders can be used around the circumference of each rotating member with one row performing as intake stroke and compression stroke and the other row performing as the work stroke and the exhaust stroke.

Title: Beverage brewing system
Inventor: HOLCOMB ROBERT R
IPC: A47J31/00
Filed: 1991-05-24
Abstract: ABSTRACT OF THE DISCLOSURE      Beverage brewing and/or warming systems benefit from water treatment and, in some cases, the elimination or reduction of the amount of AC heat heretofore provided for such devices.  Water treatment is provided in the present invention by using magnetic treatment or electromagnetic treatment by direct injection in the fluid stream or a combination of such water treatment systems.  Treatment preferably occurs prior to mixing of the heated brewing fluid and the beverage powder, but improved brewing also results from treatment at the discharge side of the brewing container, e.g. the discharge of a filter holder. Improved taste and a reduction in the amount of coffee used to obtain a desired taste level results from such treatment, and the holding qualities are also improved. The bitter taste resulting from extend holding periods can be minimized or eliminated.  Magnetic treatment may employ a multi magnet concept to create sharp field boundaries, or other magnetic water treatment devices.  Fluid or DC resistance heating may be used to eliminate the undesirable effects of AC current on the brewed beverage, and holding qualities may be improved still further by embedding a magnetic treater in a pot warming device.

Abstract: The invention relates to a radar apparatus having a wideband preselector filter (15), a wideband preamplifier (16), a narrowband IF filter (19) and a jamming indicator (11). In order to obtain a warning against a jammer being active within the large bandwidth of the preselector filter (15) but outside the narrowband IF filter (19), the jammer indicator (11) has the same bandwidth as the wideband preselector filter and is connected after the preamplifier (16), but before the narrowband IF filter (19). A warning is necessary as a jammer of this type may greatly reduce the sensitivity of the radar apparatus by saturating the preamplifier (16).

Title: Low offset voltage unity gain buffer amplifier
Inventor: JOST STEVEN R
IPC: H03F1/30
Filed: 1991-06-18
Abstract: A buffer amplifier configuration simultaneously reduces d.c. voltage offsets through the signal flow path between its input (20) and output (50) and maintains a high input impedance and a low output impedance. In a preferred embodiment, high impedence is achieved by coupling the input transistor (201) collector (204) to a high impedance current source (210), which is coupled to one of the buffer's power supply rails (22). The emitter (206) of the input transistor (201) is coupled to the input terminal (20) and its base (202) to the base (212) of a like polarity bipolar output transistor (211), the emitter (216) of which is coupled to an output terminal (50) and the collector (214) of which is coupled to one supply rail (22). Since both the input and output transistors are of the same polarity type (so that they can be reasonably well matched during manufacture) and have their base-emitter junctions connected back-to-back between the input and output terminals, they impart effectively no Vbe-based d.c. offset voltage through the buffer. To ensure a high input impedance regardless of output load and output stage gain an isolating emitter-follower transistor stage (221) is preferably coupled between the collector (204) of the input transistor stage (201) and the base (212) of the output transistor stage (211).
