Patent CA-2134533-A1 (CA)
Inventor: LO JIUAN P
IPC: E05B73/00
Filed: 1994-10-27
Abstract: A rekeyable cylinder and its keys include a  core and  a  plug. A plurality  of  pin  cell  is  formed respectively in the core and plug and is perpendicular to the axis of keyway in the plug.   Each pair of pin cells  have  a  spring,  an upper pin  and  a  lower pin disposed therein.  In locking status, upper pin is moved into pin cell of plug,  and lower pin is moved  into keyway,  thereby plug cannot rotate or move  in axial direction.  A first control pin is disposed at one end of the core and engages with an annular groove formed around the circumference of the plug, thus allowing the plug to rotate but  cannot make  linear movement.   A control key can release the first control pin from the annular groove thus allowing plug be pulled out of the core.   The lower pin in the plug can be changed and adjusted to match a new key cut profile of a new change key.   Thus a change key can be replaced without to replace the cylinder.

Title: Process for obtaining ultra-high modulus line products with enhanced mechanical properties
Inventor: ZACHARIADES ANAGNOSTIS E
IPC: A61C15/04
Filed: 1994-12-20
Abstract: A method of producing high modulus and high strength products of polyethylene and other thermoplastic polymers by swelling with a suitable solvent a melt crystallized, or compacted powder morphology to form a pseudo-gel, drying the pseudo-gel,  compressing  it,  and drawing  it.   The optimum process involves swelling the initial morphology in the form of a tape/ribbon/rod/monofilament/sheet/tube in a non-volatile  solvent  at  temperatures  near  the  polymer crystalline melting point,  cooling the morphology under controlled conditions, lightly compressing it to remove the non-volatile solvent, extracting the non-volatile solvent by volatile solvent,  removing the volatile solvent by evaporation or vacuum, compressing the morphology between rolls, and then stretching it at temperatures below the crystalline melting point of the polymer to obtain tapes, ribbons,  monofilaments,  sheets  or  tubes  with  improved mechanical properties.   Products from the method include improved dental floss,  fishing line and numerous other applications.

Patent CA-2147456-A1 (CA)
Title: Method of sonic logging while drilling a borehole traversing an earth formation
Inventor: KOSTEK SERGIO
IPC: G01V1/48
Filed: 1995-04-20
Abstract: The present invention is directed to sonic logging while drilling. A  transmitter and at least one receiver are mounted on a drill collar far performing sonic investigations of the formation traversed by a borehole. It has been discovered that a drill collar has a natural stop band or notch where acoustic energy propagating in this frequency range is severely attenuated. Thus, to reduce drill collar acoustic coupling, the transmitter is operated within this natural stop band of the drill collar. An imperforate stop band filter is also included between the transmitter and receiver to enhance the natural stop band. The transmitter is mounted transverse to the longitudinal axis of the drill collar, and is preferably mounted within means that reduce drill collar acoustic coupling. The transmitter preferably includes a material whose acoustic response is more favorable along its longitudinal axis relative to its radial axis, thereby directing the acoustic energy into the formation rather than the surrounding drill collar. Received acoustic energy waveforms are electronically processed to reliably detect, in the presence of drilling noise, those acoustic signals which are produced by the transmitter and transmitted through the formation.
