Title: Blowout preventer protector and method of using same during high pressure oil and gas well stimulation
Inventor: DALLAS MURRAY L
IPC: E21B43/25
Filed: 1997-01-14
Abstract: An apparatus for protecting blowout preventers during well fracturing and/or stimulation treatments is disclosed. The apparatus includes a hollow spool with spaced-apart inner and outer sidewalls that define an annular cavity. A mandrel is forcibly reciprocatable in the cavity. The mandrel includes an annular seal at abottom end for sealingly engaging a bit guide attached to a top end of the casing. The apparatus is mounted above a BOP attached to a casing spool of the well before well stimulation procedures are begun. The mandrel is stroked down through the BOP to protect it from exposure to fluid pressure as well as abrasive and/or corrosive well stimulation fluids, especially extreme pressures and abrasive proppants. The advantage is a simple, easy to operate apparatus for protecting BOPs which provides full access to the well casing with well servicing tools to facilitate well stimulation at pressures approaching the burst pressure rating of the well casing.

Title: Pulsed-tone timing exercise method
Inventor: ROMNEY JULIE B
IPC: G09B19/04
Filed: 1995-07-25
Abstract: A pulsed-tone timing device (10) includes pulsed audible guide tones activated at an initial pulsing rate when on-off pause key (14) is pressed. The pulsing rate is manipulated so as to repeatably (i) increase the pulsing rate over a time span to an intermediate pulsing rate and (ii) abruptly drop the pulsing rate to a decreased rate between the intermediate pulsing rate and a previous rate, until a predetermined final pulsing rate is reached. The pulsing rate can be manipulated by rate keys (22a and 22b) such that each subsequent intermediate pulsing rate pulses at a faster rate than previous intermediate pulsing rates. The method can be used in many activities. For example, a reader can read a line of text per each guide tone while keeping pace with the specifically timed rate increases, thereby increasing reading effort and reading speed.

Title: Method for the detection of lysozyme using a protein error indicator dye in conjunction with an alkane sulfonic acid
Inventor: PUGIA MICHAEL J
IPC: G01N33/52
Filed: 1997-09-03
Abstract: The determination of lysozyme in urine is carried out by contacting the urine with a reagent system containing a buffer and a protein error indicator dye. Other proteins normally found in urine can compete with the lysozyme for interaction with the protein error indicator thereby affecting the specificity of the test for lysozyme. The present invention involves the addition of certain alkyl sulfonic acids or sulfonates to increase both specificity and sensitivity of the reagent for lysozyme.

Patent CA-2216145-A1 (CA)
Title: Disposable pull-on pant
Inventor: ASHTON GREGORY
IPC: A61F13/49
Filed: 1996-04-03
Abstract: Pull-on garments provided with breathability in the side panels (64), the back waistband panel (60), and preferably the leg flap panels (58). The moisture vapor transmission rate of the side panels in conjunction with the overall vapor transmission rate of the rest of the absorbent article assists to reduce the incidence of heat rash and other skin problems associated with high heat and humidity conditions.    Further, the use of waistbands and leg bands having lower forces to reduce pressure on the skin while relying more upon the forces of the side panels to maintain the product on the wearer further reduce these problems.

Inventor: SANVIDO SAVERIO
IPC: H04B10/118
Filed: 1997-10-23
Abstract: The optical bench (10) contains a bench structure (20) and at least two optical units (12, 14, 16) fastened to the branch structure (20), whose axes are essentially oriented at predetermined angles transversely in respect to the bench structure. The bench structure (20) has a receiving element (22, 24, 26) for each optical unit (12, 14, 16), in which respectively an end section of the optical units is fastened. The remaining parts of the optical units (12, 14, 16) freely project away from the bench structure (20) in the direction of their axes (13, 15, 17).  In a first variant,the receiving elements are connected by arms, which can be integrated into a thin plate. In a second variant, the optical bench has a radiation shielding plate (50) covering the area of the optical units (12, 14, 16), which is disposed on the side of the bench structure (20) facing away from the optical units (12, 14, 16) and preferably is resiliently fastened, so that bending or tilting of the radiation shielding plate (50) has no effect on the orientation of the axes (13, 15,17). When using the optical bench (10) in a satellite of a telecommunications device in space, its size is determined by taking the occurring changing loads and the loads encountered during the start phase of the launch rocket into consideration.

Patent CA-2222389-A1 (CA)
Inventor: GALLOP PATRICK GEORGE
IPC: G06F9/46
Filed: 1997-11-27
Abstract: A mechanism for managing the locking and unlocking of objects. The mechanism comprises a transition vector having an ordered set of transition elements. Each of the transition elements includes a locking function or a pointer to the locking function and an unlocking function or a pointer to the unlocking function. When an object is created a transition vector is assigned to the object. The object includes a reference element which references a transition element in the vector. In response to a request to lock the object, the locking function in the transition element is invoked and the next transition element is assigned to the object and the reference element in the object is updated. For a request to unlock the object, the unlocking function in the transition element is invoked and the previous transition element is assigned to the object and the reference element is updated. The mechanism improves execution overhead by providing an implicit count for determining the lock count on an object. The mechanism also features typed transition vectors for structured locking/unlocking and unstructured locking/unlocking operations.

Patent CA-2225082-A1 (CA)
Title: An inverted e-shaped antenna
Inventor: SMITH MARTIN STEVENS
IPC: H01Q9/04
Filed: 1997-12-17
Abstract: The present invention relates to radio communications antennas and in particular relates to an antenna for such. An inverted E-shaped antenna is disclosed comprising a radiating element and a ground plane. The antenna is suitable for placement in a mobile communications handset.      The antenna finds particular applicability in dual mode handsets, where two or more antennas may be located in close proximity. The small dimensions of the antenna relative to the operating wavelength, achieved by folding back an element of the antenna, provides a simple solution to such problems as antenna coupling since its small size allows it to be placed as far away as possible within the small confines of a radio communications handset. A method of operating a mobile communications arrangement is also disclosed, the arrangement comprising a microphone, an audio speaker, a transceiver, and an antenna, wherein the antenna is in the form of an inverted E.
