Title: Child resistant package
Inventor: KONEFAL ROBERT S
IPC: B65D41/04
Filed: 1998-11-26
Abstract: A child resistant package which includes a container having an open end and single or multiple threads on the external surface of the container adjacent the upper end. A closure having a peripheral skirt has an inner surface formed with single or multiple threads corresponding in number to the threads on the container for engaging the threads on the container. A deflectable release element is formed integrally on the container. The release element includes an integral axially deflectable lug extending upwardly toward the open end of the container. The closure has at least one locking lug on the skirt of the closure, the number of locking lugs preferably corresponding to the number of threads on the container and closure. The deflectable lug on the deflectable release element normally extends upwardly for engagement with the locking lug such that when the release element is pressed radially inwardly, the lug is disengaged from engagement with a locking lug and the closure can be removed by unthreading the closure from the container. When the closure is reapplied minimal torque is required due to the axial deflection of the deflectable lug and one of the locking lugs on the closure moves past the lug.  In a preferred form of the child resistant package, the deflectable release element and container include interengaging stops to limit the deflection on the release element.

Patent CA-2257585-A1 (CA)
Title: Transducer supply
Inventor: STRUETT BERND
IPC: G08C19/02
Filed: 1998-12-29
Abstract: The transducer supply is configured for supplying a passive transducer arranged in an explosion-hazard zone with electrical energy from a DC voltage source.  The electrical  energy  is  transmitted  via  a  two-wire connection,  via which in the opposite direction the measured value sensed by the transducer is transmitted by the transducer setting the direct current obtained from the DC voltage source to a value variable between two  limit  values.  As  a  means  of  protection  a transformer  is  inserted  in  the  two-wire  connection which affects  DC  decoupling.  The  direct  current  is chopped  in  accordance  with  the  principle  of  a  DC voltage  converter  at  the  primary  side  of   the transformer and re-rectified on the secondary side. To permit connection of an active transducer instead of a passive transducer,  the active transducer having its own  energy  supply  and  furnishing  at  its  output connections a direct current in a quantity representing the measured value,  an adapter circuit controlled by the output current of the active transducer is inserted between the output connections of the rectifier circuit and the connecting terminals provided for connecting the active transducer, this adapter circuit loading the rectifier  circuit  with  a  direct  current  which  is proportional  to  the  output  current  of  the  active transducer.

Patent CA-2259130-A1 (CA)
Inventor: SCHLIENGER MAX P
IPC: C22B9/02
Filed: 1997-05-13
Abstract: Slag from a pool of molten slag (34) floating on molten metal in a plasma arc treatment chamber (36) is removed by providing a slag container (38) located inside the chamber which has a slag intake pipe (40) extending from a bottom of the container (38) downwardly into the slag pool. A vacuum line (48) is connected to the top of the container and a vacuum source (46). When a vacuum is applied to the inside of the container, the pressure prevailing in the chamber pushes the slag from the pool through the intake pipe into the container. When the container becomes filled with molten slag, the latter enters a section (44) of the line communicating the top of the container with the vacuum source. As the slag enters the pipe section, it is cooled and solidified to prevent further slag flow into or gas/air flow through the vacuum line so that the container can be lifted out of the chamber while the slag in the container is still in its molten state without causing slag spillage.

IPC: G01N33/53
Filed: 1998-02-06
Abstract: Targeted C2-symmetric and unsymmetric chemical libraries for use in protein and receptor homodimerization and heterodimerization are constructed by solution phase methodologies. Exemplary libraries are prepared in a 60 to 10 sub-library format by symmetrical coupling of the constructed fragments with a mixture of tethering dicarboxylic acids. In each step of the 3-step reaction sequence, the reactants, unreacted starting material, reagents and their byproducts were removed by simple liquid-liquid or liquid-solid extractions providing the desired intermediates and final libraries in multi-milligram quantities in high purities (90-100 %) independent of the reaction yields and without deliberate reaction optimization. The synthesis of a second prototypical library employed the olefin metathesis reaction to join and combinatorially randomize the length of linker tether. This approach provides a unique opportunity to rapidly generate a statistically controlled mixture of homo and heterodimers of remarkable diversity.
