Patent CA-2091662-C (CA)
Title: Mine roof bolt
Inventor: GILLESPIE HARVEY D
IPC: E21D21/00
Filed: 1993-03-15
Granted: 1998-08-11
Abstract: An improved mine roof bolt is constructed of pre-tensioned, multi-strand steel cable.   The bolt head is constructed of a hexagonal-or other drive-headed collar having an internally tapered frusto-conical bore therethrough,  and a tapered plug having a frusto-conical outer surface that engages the frusto-conical inner surface of the drive collar.  The tapered plug has an internal bore essentially concentric with the outer frusto-conical surface, and is  adapted  to  fit  over  the multi-stranded  steel  cable,  the hexagonal head drive collar fitting over the tapered plug such that pressing the tapered plug and steel cable into the inner frusto-conical bore of the hexagonal-head drive collar causes serrations on the internal bore of the tapered plug to be urged down against, and bite into, the steel cable, resulting in a solid hexagonal head for the cable bolt.  The tapered plug is in actuality, a pair of essentially identical diametrically opposed semi-frusto-conical tapered sections that more easily compress together to bite into the multi-strand steel cable.   The improved mine roof bolt is intended for use in passive-type mine roof systems.

Abstract: An electrically conductive polymer gel is composed a crosslinked polyacrylamide polymer including electrolytic salt, water and polyhydric alcohol uniformly dissolved therein, the water and the polyhydric alcohol being major components of said polymer gel.  The polyacrylamide series polymer in the gel has properties of hydrophilic and nonelectrolyte.  Therefore, a desirable connection between the gel and the electrode can be achieved with low impedance.  Moreover, the polyhydric alcohol reduces the drying speed of the electrically conductive polymer gel, thereby preventing an increase in the impedance due to the dryout of the gel.  Therefore, the electrically conductive polymer gel of the present invention permits an accurate measurement of an electrical phenomenon in the organism for long periods of time.

Title: Chlorine dioxide generating polymer packaging films
Inventor: WELLINGHOFF STEPHEN T
IPC: C08K3/28
Filed: 1994-02-11
Granted: 1999-12-28
Abstract: A process incorporating a chlorine dioxide generating compound such as sodium chlorite into a polymer or oligomer film is coated onto various substrates. Controlled release is accomplished by absorption of moisture from the environment. The chlorine dioxide so released acts as a biocide and a fumigant. The chlorite is dissolved into a hydrogen bonded phase containing a monomeric, or polymeric amide or a monomeric or polymeric alcohol. This hydrogen bonded phase is then mixed with an incompatible apolar phase consisting of anhydride containing such as polymers such as maleic anhydride copolymers with olefins, grafted malefic anhydride-polypropylene polymers. Chlorine dioxide is released by direct reaction of the anhydride or hydrolyzed anhydride with the chlorite anion across the phase boundary. Increasing the molecular weight of the phases, increasing the phase incompatibility and decreasing the concentration of anhydride will au decrease the chlorine dioxide release rate.

Inventor: IWATA ATSUSHI
IPC: H04L12/70
Filed: 1994-12-28
Granted: 2000-07-18
Abstract: In a connection-oriented network, a normal signaling packet is sent from a source user to the network. A first virtual path identifier (VPI) is determined at a first node of the network according to a destination address in the packet, and the first VPI is inserted into the packet, and forwarded to the second node, where it determines a second VPI according to the packet's destination address, adds the second VPI to the first VPI in the packet to produce a source route, and forwards the normal signalling packet to a destination user. The destination user returns an acknowledgment (ACK) packet to the source user, containing the source route. In response ko the ACK, the source user stores the source route contained in the packet into a source route table, and selects an initial VPI and an initial virtual channel identifier (VCI) from a copy of network resource, and sends a fast signaling packet, captaining the source route, the initial VPI and VCI. At the first node, a first VCI is selected according to the first VPI in the source route of the fast signaling packet, the initial VPI/VCI in the packet are mapped to the first VPI/VCI, and the initial VCI in the packet is overwritten with the first VCI, and the packet is forwarded to the second network node, where a second VCI is selected according to the second VPI in the source route of the packet, and the first VPI/VCI in the packet are mapped to the second VPI/VCI, and the first VCI in the packet is overwritten with the second VCI, and the packet is forwarded to the destination user.

Filed: 1995-01-06
Granted: 1998-04-07
Abstract: A  solid  state  amplifier  for  emulating  the compression associated with an overbiased class-B push-pull tube amplifier at high input signal levels due to the flow of current into the grid of the output tubes resulting in a desirable output clipping characteristic with crossover distortion is disclosed. The invention includes at least one pair of class-B connected solid state devices,  each having an input circuit and an output circuit.  The output circuits are connected for mixing.  A biasing element in the input circuit of each paired solid state device establishes a clipping level offset at the input circuit and at the output circuit of each device. A clipping element in the input circuit and the output circuit clips the offset at the input circuit and clips the offset at the output circuit of each respective solid state device. A charging element overbiases the offset in the input circuit whenever the input  signal  is  greater  than  the  input  clipping element. The overbiasing causes crossover distortion for emulating the desirable compression associated with a tube amplifier.
