Patent CA-2121744-A1 (CA)
Inventor: KICH ROLF
IPC: H01P1/208
Filed: 1994-04-20
Abstract: A plural cavity structure (10), suitable for use as a microwave filter (34, 34A, 34B), has plural cavities  (24,  26,  28,  30)  disposed  within  a cylindrical aluminum housing  (12)  and having a central planar transverse wall (18)  including an iris  (38)  for coupling of electromagnetic power between two successive ones of the cavities (28, 26),  the transverse planar wall being centrally located in the case of the four-cavity structure. Additional transverse walls (14,  16, 20, 22) are constructed as discs and serve as end walls of the cavities and,  in the case of the inboard discs, the discs are provided with apertures (36, 40) to serve   as   coupling   irises   for   coupling electromagnetic power between the cavities which serve  as  resonant  chambers  of  the microwave filter.    The  transverse  walls  are  bowed,  and peripheral regions of the walls are clamped by metallic rings (66, 68, 70, 72) differing in their coefficients  of  thermal  expansion.    Thus,  the rings  (68,  70)  of the inboard transverse walls (16,   20)   are  formed  of  titanium  having  a relatively high coefficient of thermal expansion, while  the  rings   (66,   72)   of  the  outboard transverse walls  (14,  22)  are  formed  of  invar having a relatively  low coefficient of thermal expansion.     As  a  result  of  the  differing coefficients  of  thermal  expansion,  the  outer transverse walls  experience  greater  deformation than do the inner transverse walls with changes in environmental  temperature  resulting  in  a  net decrease  in  axial  length  of  both  inboard  and outboard   cavities   upon   an   increase   in environmental temperature.

Title: Miranda spinning wheel
Inventor: HUMPHRIES HENRY J
IPC: D01H1/04
Filed: 1994-06-07
Abstract: Spinning Wheels have many common features, namely, a large diameter drive wheel, made to rotate by a treadle (or treadles), and turning a smaller pulley ('whorl') by means of a belt or drive band. This small pulley is attached to what is called a 'flyer' in an assembly named 'mother of all'.  The flyer winds the spun thread on a bobbin in this assembly.    As different materials i.e. wool, cotton, silk etc. require various amounts of twist or turns per inch to create stable yarns, the ratio from the large diameter drive wheel to the small pulley on the flyer has to change.    This invention allows this speed change to be made more efficiently and easily than other methods on the market.

Title: Process and plant for decontaminating solid materials contaminated with organic pollutants
Inventor: WEBB LESLIE
IPC: C12S9/00
Filed: 1993-08-23
Abstract: In order to decontaminate solid materials contaminated with organic pollutants, in particular soil contaminated with poly-cyclic aromatic hydrocarbons, the materials are mixed with a micro-emulsion, if required after being crushed and mechanically disaggregated. The organic impurities are solubilized in the apolar compartment of the micro-emulsion and the micro-emulsion is decomposed, in particular by temperature change, into a tenside-rich phase and into a pollutant-containing phase. By using mic-ro-emulsions of biodegradable components, the purified solid materials, in particular purified soil, may be returned to the envir-onment. A plant for carrying out the process has a multiple-stage extraction device (3), in which the contaminated solid material is mixed with the micro-emulsion and the impurities concentrate in the apolar oil phase. In a separating device (6), the extracted solid material is separated from the contaminated micro-emulsion, which is then decomposed in a phase separating device (8) in-to a tenside-rich water phase, collected in the container (11), and into a pollutant-containing oil phase (oil container 12). By using biodegradable components for the micro-emulsion. the pollutant-containing oil phase can be reacted in a micro-organism reactor (14) in order to achieve its total degradation.

Patent CA-2150459-A1 (CA)
Title: Removing the effects of acoustic ringing and reducing temperature effects in the detection of explosives by nqr
Inventor: BUESS MICHAEL L
IPC: G01R33/44
Filed: 1993-10-25
Abstract: Acoustic ringing and adverse effects from variations in the NQR detection of explosives and narcotics are minimized or eliminated. A specimen (1) is irradiated with a modified shady state free precession (SSFP) pulse sequence which combines a phase-alternated pulse sequence (DAPS) with a non-phase-alterned pulse sequence (NPAPS). The resulting signals from the PAPS and NPAPS may then be coadded to cancel out the FID contributions to the signals. By canceling out the Fm contributions to the signals, the effects of probe ringing and other extraneous responses, as well as the effect of temperature variation, arc minimized or removed. The present method is especially effective in the detection of explosives and narcotics having 14N  or 35,37C1 nuclei. A steady state free precession pulse which is especially useful with the method of the present invention is the strong off resonance comb (SORC). In another embodiment of the invention, the effects of probe ringing can also be minimized or removed by repeating the detection procedure at a frequency which is sufficiently off-resonance so that only frequency independent effects, such as probe-ringing, can be observed.

Patent CA-2154939-A1 (CA)
Title: Compressed gas-blast circuit breaker
Inventor: HOFBAUER WERNER
IPC: H01H33/90
Filed: 1995-07-28
Abstract: The compressed gas-blast circuit breaker includes two moving contact members  (1,  2)  which are guided such that they move counter to one another along an axis (3) in a chamber which is filled with insulating gas. These contact members each have an erosion contact (8, 9) and a rated current contact  (6,  7). An insulating nozzle (10) is mounted on a contact member (1) which is moved directly by a drive,  and compressed gas  is  passed, during disconnection through the constriction (11)  in said insulating nozzle (10) from a pressure space (12), which is independent of the switching travel, and/or a compression space  (19),  which  is  operated  by  the contact  members,  into  an  exhaust  space  (14).  Drive force is passed to a contact member (2), which absorbs force, from the directly driven contact member (1), via an insulating part and a speed converter.        Such a circuit breaker requires a small amount of  drive  energy  and  has  a  compact,  cost-effective design.  During  disconnection,  if  the  functionally essential parts of the force-absorbing contact member (2), such as the erosion contact (9), the rated current contact  (7)  and the shields, are suitably driven,  it forms an insulating path, which can be highly stressed dielectrically, in a short time while optimally using a comparatively small drive force.
