IPC: E21B10/02
Filed: 1995-10-06
Granted: 1999-01-12
Abstract: A drilling bit includes a carrier member shaped, for instance, as a hollow annular crown. In such a crown several cutter members are distributed angularly apart around the circumferentially extending leading end of the carrier member. The cutter members project both radially outwardly and inwardly from the wall thickness of the carrier member. A step (S) is formed in the cutter members spaced from the leading end thereof in the drilling direction. The step(S) is located at the trailing end of a region (K) with a continuous reduction in the radial dimension (R) of the cutter member and the radial dimension is further reduced at the step. Due to the further reduction in the radial dimension at the step (S), the length of the cutter member in the drilling direction, causing friction with the wall surface of the borehole to be drilled, is limited after extended use of the drilling bit, so that the drilling bit retains a higher drilling efficiency even after such extended use.

Title: Multiple mode personal wireless communications system
Inventor: ZICKER ROBERT G
IPC: H04M1/72505
Filed: 1995-01-31
Granted: 2005-04-12
Abstract: A multiple mode, personal, wireless communications system is provided herein which exists within a radiotelephone network serving general customers and provides additional services to a select group of customers. In one embodiment, the system uses handsets which automatically switch between a standard cellular radiotelephone mode of operation and an enhanced cordless mode when the handsets are within range of pico cells that are interconnected to the public switched telephone network. Each pico cell is controlled via a framework of overlay cells that operates independently of the radiotelephone network and uses a unique control protocol on a small number of reserved cellular channels. Each pico cell consists of a spectrally-dynamic, non capturing, frequency-agile, multi-purpose base station which is provided at customer-selected locations to cooperate with the overlay cell framework. Each pico cell is capable of supporting multiple handsets and uses low power operation that achieves limited coverage, and reduces traffic on the standard cellular radiotelephone network by independently handling registered handsets. An alternate line option module provides wireless local interconnect capability to selectively route call traffic between land lines and the standard cellular radiotelephone network. Service control units and host stations facilitate wireless activation and control of each pico cell and handset via the overlay cell framework. The multiple mode telecommunication system may further include a portable handset with a single transceiver which is capable of operating in accordance both with a first wireless control protocol and with a second wireless control protocol. The first wireless control protocol has a post-activation registration session which is initiated by the handset transmitting a reverse channel message without receiving a corresponding forward channel message. The second wireless control protocol has a post-activation registration session which is initiated by the handset transmitting a reverse channel message after receiving a corresponding forward channel message stream. A local base station includes a transceiver which is capable of exchanging communications with the handset in accordance with the first wireless control protocol when the handset is within a local range of the local base station. Switching means are coupled to the handset transceiver, for automatically setting the handset transceiver to engage in communications with a land station under the second wireless control protocol when the handset is moved beyond range of the local base station.

Abstract: A device and method for removing ice and snow from roofs whereby a flexible sleeve attached to the lower part of a roof is remotely inflated, thereby shattering the ice in a controlled and safe manner. In the preferred embodiment, a mounting frame is sealingly attached to the roof surface and is configured to removably retain the flexible, inflatable sleeve in position on the roof. A number of retention means are disclosed.  However, the preferred means is a zipper assembly, which is easy to operate and retains the overall flexibility of the inflatable sleeve to allow it to be rolled up for easy storage when it is removed from a roof. The lower end of the inflatable sleeve extends beyond the lower edge of the roof surface where it is movably secured to the edge of the roof. An operator realizing the need to remove ice from a roof remotely inflates the sleeve with a low pressure air supply. The expansion of the sleeve attached to the roof shatters the brittle ice. The movable attachment to the lower edge of the roof allows the sleeve to expand and still retains it in a taught manner when the sleeve is not inflated to prevent flapping in windy conditions.

Abstract: A gas drying canister housing for a desiccant canister in a gas dryer system includes a main portion having an upper base and a lower portion having a lower base.  A canister bore is defined between the upper and lower bases when the main and lower portions are fastened to each other.  The main portion defines a supply port through which a stream of moisture-bearing gas is directed into the housing for passage through the desiccant canister during a drying mode of operation of the gas dryer system.  The main portion also defines a delivery port through which a stream of dried gas is directed from the housing during the drying mode.  The lower portion defines a purge port through the lower base through which a stream of remoisturized gas is expelled from the housing during a purge mode of operation of the gas dryer system.  The upper base of the main portion features a sealing flange against which an outer rim portion of a top of the desiccant canister is seatable so as to make an air tight seal therebetween.   The gas drying canister housing further includes a mechanism for aligning and securably retaining the desiccant  canister  within  the  housing  such  that  when  the desiccant canister is so aligned and securably retained the top of the desiccant canister aligns with and seals against the sealing flange and communication between the supply and delivery ports of the housing is possible only through the desiccant canister.

Title: Two terminal active arc suppressor
Inventor: LEE TONY J
IPC: H01H9/54
Filed: 1997-04-29
Granted: 2001-09-11
Abstract: The arc suppression circuit includes an insulated gate bipolar junction transistor (IGBT) connected across the electrical switch contacts to be protected. When the contacts open, the combination of added Miller capacitance and the gate-to-emitter capacitance of the IGBT results in the IGBT turning on. The IGBT is quickly turned off thereafter by a second transistor, which turns on as the voltage across the suppression circuit rises following turn-on of the IGBT. The turning on of the second transistor results in the first power transistor quickly and abruptly turning off so that relatively little of the load energy is dissipated in the power transistor.

IPC: G08B27/00
Filed: 1997-05-01
Granted: 2001-03-20
Abstract: A network of identical atmospheric hazard detectors communicates a locally sensed hazard condition directly to multiple neighboring detectors using RF command communication, without the use of wires and without a central control location.  Each detector includes a sensor of an atmospheric hazard, a detection circuit for measuring the sensor output and creating a local hazard signal, an alarm indicator, an RF transmitter for sending a neighboring hazard signal to the network, and an RF receiver for receiving a neighboring hazard signal from the network.  The local alarm and neighboring alarm control signals produce discernibly different alarm indications from the detector's alarm device, facilitating an attempt to locate the origin of a hazard.  In the preferred embodiment, every detector functions as a receive/transmit relay station, enabling the network to be extended in spatial expanse without limit and without increasing the power output of the RF transmitter.  Auxiliary devices are included, for example, a radio controlled light for emergency illumination.
