Abstract: ABSTRACT      A garden trowel includes a handle, a blade, and a connection member interconnecting the handle and the blade. The handle has a length which accommodates the use of two hands. The blade includes a body portion and a stem portion. The body portion of the blade has a beveled edge. The stem portion of the blade is bent and is attached to the connection member. The bent stem portion of the blade effectively offsets the blade from the handle. The handle of the trowel is formed in an offset manner along a longitudinal axis.      More particularly, the handle is rotationally offset in a range between about four and about six degrees with respect to a vertical plane intersecting the longitudinal axis (to the right for a right handed trowel and to the left for a left handed trowel). The handle includes an increasing, graduated size of the handle that extends from a forward end of the handle to a rear end of the handle. The forward end of the handle is connected to the blade via the connection member. The rear end of the handle includes first and second tapering, flattened sides which greatly increases the grip and turning power of the blade of the trowel much facilitating any kind of digging encountered.

Abstract: Up until now, the task of rubbing animals, in particular horses, ponies or the like, dry once they have been washed (showered) has involved strenuous manual work. The effort involved in this rubbing-dry action means that the horses are often dried insufficiently and this results, in particular, in them catching chills. The invention proposes an apparatus for drying animals which has a housing (11) with air-outlet openings on the underside (16). The housing (11) is assigned fans (39), for generating an air flow, and air-distributing plates (45), as a result of which a uniform air stream is generated. This uniform air stream is heated by flowing along plate convectors (33) and then passes out of the housing (11) at the bottom as hot air through both air-outlet holes (21) and air-outlet slits (28). A hot-air flow generated in this way makes it possible for animals, in particular horses, to be dried carefully and effectively.

Title: Combination motor/pneumatic driven train brake pipe pressure exhaust valve
Inventor: BEZOS ANGEL P
IPC: B60T15/18
Filed: 1997-08-13
Abstract: A microprocessor controlled valve system is used with an EOT unit on a railcar remote from the locomotive of the train.      The system includes a pressure transducer, a microprocessor, a valve device, a motor drive and a pneumatic drive. The microprocessor receives from the transducer an electrical signal indicative of actual brake pipe pressure and from the locomotive a brake command signal indicative of desired brake pipe pressure. The microprocessor issues a drive signal when the brake command signal requires a service brake application and an actuating signal when the brake command signal requires an emergency brake application. The valve devices defines an elongated bore, a primary passage, a branch passage, an exhaust passage and an elongated valve body able to move reciprocatingly in the bore according to the operation of the drives. The primary and branch passages communicate with the brake pipe, and all of the passages communicate with the bore.      The valve body feature (A) a first valve that when opened allows at least partial communication between the primary and exhaust passages and (B) a second valve that when opened allows communication between the branch and exhaust passages.      The motor drive opens the first valve in response to and to the extent dictated by the drive signal. In response to the actuating signal, the pneumatic drive fully opens the second valve thereby fully opening the first valve so that pressure in the brake pipe flows through the valves and vents via the exhaust passage.

Patent CA-2330075-A1 (CA)
Inventor: SAND PAUL RAYMOND
IPC: H04M11/00
Filed: 2001-01-02
Abstract: Apparatus and a method for providing roaming service to a telecom-munications station which can act as a cellular station or if plugged into a jack connected to a land-line switch, can act like a land-line telephone. When such a Universal Main Station (UMS) is plugged into a jack connected to a land-line switch, the station calls a server system which obtains the directory number corresponding to the jack into which the UMS was plugged. The server notifies a home switch of said UMS to forward calls to that directory number. When the UMS subsequently unplugs from the jack, the UMS registers as a mobile station and the home switch is notified to forward calls to the UMS, acting as a mobile station and identified by a secret directory number, identified in the course of the registration. Advantageously, this arrangement allows a mobile station equipped with an arrangement for detecting the presence of land-line power and arranged to substitute signals received from a jack for radio signals to roam widely, and to receive a choice of cellular service or land-line service wherever the station roams.

Title: Delay combiner system for cdma repeaters and low noise amplifiers
Inventor: FUERTER MATTHEW P
IPC: H04B7/08
Filed: 1998-12-30
Abstract: Signal delay and combining techniques are used with multipath signals to provide signal diversity gain within CDMA over-the-air repeater and low noise amplifier systems. An incoming signal from a remote user is typically processed through two processing paths, wherein one path adds a delay to the processed signal. The two signal paths are then combined and filtered through a sharp band pass filter, preferably a SAW filter. In an over-the-air repeater, the filtered signal is retransmitted towards a CDMA rake receiver at a base station, which can process the multipath signal to produce a clean signal representation. In a low noise amplifier, the filtered signal is transferred directly into a base station or repeater. The use of SAW filters protect the latter stages of the low noise amplifier, and also protect the base station from out-of-band signal interference. A quadruple diversity low noise amplification system for base stations embodiment is also disclosed, which provides quadruple diversity and improved sensitivity for CDMA base stations.
