Patent CA-2169190-A1 (CA)
Title: Method for preparing orphan receptor ligands
Inventor: HOLLY RICHARD D
IPC: A61K35/12
Filed: 1995-02-08
Abstract: Methods for obtaining cells that produce a ligand for an orphan receptor and methods for preparing polynucleotide molecules that encode ligands for orphan receptors are disclosed. The methods utilize growth factor-dependent parent cells that are transfected with a DNA construct encoding an orphan receptor. The transfected cells are exposed to mutagenizing conditions, and the mutagenized cells are cultured under conditions in which cell survival is dependent upon autocrine growth factor production. Progeny cells are recovered and screened to identify those that produce a ligand for the orphan receptor. Polynucleotide molecules encoding the ligand can be prepared from the identified cells.

Title: Catalyst composition for copolymerizing ethylene
Inventor: MINK ROBERT IVAN
IPC: B01J31/02
Filed: 1994-11-14
Abstract: An ethylene copolymerization catalyst is prepared by impregnating a porous support, such as silica, with an organomagnesium compound such as a magnesium alkyl and contacting the magnesium-containing support with a silane compound which is free of hydroxyl groups, such as a tetraalkyl orthosilicate e.g. tetraethyl orthsilicate (TEOS). A transition metal component such as titanium tetrachloride is then incorporated into the support in a specific ratio to the magnesium and silane components. Activation of this catalyst precursor with a trialkylaluminum compound results in a catalyst which is effective for the production of ethylene copolymers.
Patent CA-2176170-A1 (CA)
Inventor: PETRUCCELLO JOHN P
IPC: F16C1/14
Filed: 1996-05-09
Abstract: A motion transmitting remote control assembly has a conduit, a core element, and an end fitting molded about one end of the conduit. The end fitting is generally cylindrical and has a plurality of annular locking grooves and is fitted with an O-ring seal. A connector is molded separately from the end fitting and has snap-lock tabs for attachment to a support structure. A receptacle extends into the connector from one end thereof and is accessible from above through a transverse passage. The end fitting is insertable axially into the receptacle through its open end to support the connector for rotation about seal between the end fitting and connector. The O-ring provides a fluid-tight seal between the end fitting and connector to protect the core element from corrosive elements. The end fitting is retained in the receptacle by a locking member having U-shaped locking portions that are extendible through the transverse passage into nesting engagement with the locking grooves of the end fitting to secure the end fitting against removal from the receptacle while retaining the relative rotatability of the connector and end fitting. This assembly allows control of tolerances to provide improved rotation between the end fitting and connector by preforming these parts before assembly. Also, a number of difference connector styles may be prefabricated to install a selected connector depending upon the particular end user.

Title: An electrosurgical generator and system
Inventor: GOBLE NIGEL MARK
IPC: A61B18/00
Filed: 1996-06-14
Abstract: An electrosurgical system including an electrode assembly having two electrodes for use immersed in an electrically conductive fluid has a generator with control circuitry for rapidly reducing the delivered radio frequency output power by at least 50%  within at most a few cycles of the peak radio frequency output voltage reaching a predetermined threshold limit. In this way, tissue coagulation can be performed in, for example, saline without significant steam generation. The same peak voltage limitation technique is used in a tissue vaporisation or cutting mode to limit the size of the steam pocket at the electrodes and to avoid electrode burning.

Title: Improved cord closure
Inventor: FRANO FRANK
IPC: F16G11/10
Filed: 1996-09-18
Abstract: A cord closure having a housing with an open end, a surrounding side wall and a closed end which forms a cavity for receiving a plunger.  The plunger has a body with a throughhole alignable with holes formed through opposing sides of the housing and a stem extending from a shoulder portion of the body with a resilient retaining member on a distal end portion of the stem.  A bias spring is disposed about the stem of the plunger and is releasably retained in compression on the plungerbetween the shoulder portion of the body and the resilient retaining member.  At least a portion of the body and the stem of the plunger are reciprocally disposable in the cavity so that the throughhole of the plunger is alignable with the hole formed through opposing sides of the housing to permit threading of a cord through the aligned holes of the cord closure without the bias spring urging the plunger away from the housing. The housing includes a release means disposed in the closed end of the cavity for engaging the resilient retaining member to release the bias spring from the releasable retaining member when the plunger is depressed into the cavity of the housing whereafter the bias spring urges the plunger away from the housing to engage andretain the cord threaded through the holes of the cord closure.

Title: Apparatus and method for transmitting a signal
Inventor: DEMONT JASON PAUL
IPC: H04M3/42
Filed: 1996-12-02
Abstract: A method and apparatus for initiating a telecommunications call. A plurality of beacons (102,) are geographically disposed in a telecommunications system (100). Each beacon (102n) radiates an electromagnetic carrier that is modulated with an identifying address (e.g., a telephone number, an Internet address) for an associated terminal. An identifying signal is stored in a memory (206). A controller (208) modulates a carrier with the identifying signal and a transmission element (210) transmits the carrier to allow a communications terminal (104) to initiate a call to the associated communications terminal (114, 116). A wireless terminal (104a) includes a directional receiver (204). To initiate a call, a user points directional receiver (204) at a beacon. The directional receiver (204) receives the electromagnetic carrier and the wireless terminal recovers the identifying address. Wireless terminal (104) then uses the identifying address to initiates a call, in well-known fashion, to the communications terminal associated with the identifying address.

Title: Antifuse based on silicided single polysilicon bipolar transistor
Inventor: CERVIN-LAWREY ANDREW V C
IPC: H01L27/082
Filed: 1997-02-14
Abstract: An improved antifuse which employs the base-emitter junction of a silicided single polysilicon bipolar transistor. The distance between the base metal and emitter metal is shortened and results from self aligning process steps rather than lithographic steps, resulting in a lower and better controlled programming voltage, programming energy and ON state resistance. Typically the conductive filament formed in the new antifuse is about 0.65 microns long and is formed by a voltage pulse having a relatively slow rise time (e.g. 150 microseconds), resulting in improved properties which provide advantages in circuit design and in manufacturing circuits using the new antifuse.
