Title: Box support
Inventor: LAUGHLIN RAYMOND S
IPC: H02B1/015
Filed: 1989-12-12
Granted: 1994-11-15
Abstract: ABSTRACT OF THE DISCLOSURE An electrical box support assembly for stud wall construction includes two channel shape struts with one being confined by and telescoping in the other. Both have a longitudinally extending V-shape groove opening toward the box or boxes to be supported thereon whereby the boxes may quickly be attached by a self tapping screw with a screw gun. The groove ensures that each box is straight and, if more than one box is mounted, both straight and aligned. While the two parts may be telescoped they are not readily separable and are sufficiently rigid so that they do not need to be preassembled. The opposite ends of the struts are each provided with planar tabs with two longitudinally spaced designed bend points at which the strut ends or tabs may selectively be field bent to form right angle flanges matching the depth of the box to be supported. The tab ends of the struts are shipped straight or flat and in some forms may include one or more additional bend points which, when the strut end tab is selectively bent, may be used to form a flange substantially parallel to the strut. The parallel flange may be the full width or one-half the width of the stud. The field formed flanges may be provided with holes to facilitate the screw gun fastening of the strut ends to substantially any surface of the stud. If a projecting portion of the tab is not employed, it may simply be folded back on itself to form a double thickness end.

Granted: 1998-05-12
Abstract: A condenser is positioned in high-pressure refrigerant line of a cooling system. The condenser is formed of thermally-conductive material defining a closed reservoir for accumulating liquid refrigerant. An inlet receives the refrigerant flow from the high-pressure line and an outlet discharges the accumulated liquid refrigerant to an expansion valve. The conduit within the reservoir conducts the refrigerant flow from the inlet to a region of the reservoir above the outlet. The conduit is apertured to direct substantially all of the refrigerant flow against upper portions of the condenser, specifically against one side of the condenser. That side of the condenser is exposed to the flow of cold fluid medium (typically air) produced by the system to condense a gaseous component of the refrigeration flow.

Title: A method of locating a mobile station in a mobile telephone system
Inventor: GHISLER WALTER
IPC: H04W36/04
Filed: 1993-03-09
Granted: 2002-10-01
Abstract: A mobile telephone system has in a cell (C1) a base station (BS1) and sub-stations (MT1, MT2, MT3) which are connected to a mobile switching central (MSC) by means of cables (2). The mobile telephone system has control channels (CC) and frequencies which are time divided to traffic channels. Some of the frequencies are selected as identification frequencies. Each of the sub-stations (MT1, MT2, MT3) is assigned a unique set of frequencies from among the identification frequencies and constantly transmit their respective frequency set. A mobile station (MS) connected to the base station (BS1) listens to the identification frequencies and reports the strongest of these frequencies to the mobile switching central (MSC). The mobile switching central compares the reported frequencies with the unique set of frequencies, compares the reported signal strength with a threshold value and selects the nearest sub-station (MT2) for handoff. The mobile switching central (MSC) switches from the base station (BS1) to a connection (4) with the sub-station (MT2). The mobile station (MS) continues to listen to the identification frequencies and reports the signal strength on its connection (4). When the strength of the signals from the selected sub-station (MT2) is low, the connection (4) is switched back to the base station (BS1).
