Abstract: ABSTRACT OF THE DISCLOSURE:           This invention relates to compositions of formula (I):                   Q3XW4O24-2n             (I) wherein:  Q represents a cation of an "onium" salt;           X is either a P or As atom, while n is a number chosen between 0;1 and 2. These compositions can be prepared by in reacting an  oxygenated tungsten (VI) derivative, an oxygenated P (V) or As (V) derivative and hydrogen peroxide, in an aqueous acid phase, with a "onium" salt or a precursor thereof possibly contained in an organic phase unmixable with the aqueous phase, at substantially room temperature.  The oxygenated compounds of W (VI), P (V) or As (V) may possibly be prepared 'in situ' under the conditions of the reaction. The compositions (I), which show up as solids or as viscous oils, find their use as oxidizing agents in general in oxidation processes, and especially as epoxydation catalysts for olefinic compounds, both in a homogeneous phase as well as in a heterogeneous phase, and preferably according to the phase-transfer technique, in the presence of oxidizing agents.

Title: Endoscope
Inventor: COLLINS IAN P

Filed: 1983-11-18
Granted: 1986-05-27
Abstract: IMPROVED ENDOSCOPE An endoscope has a shaft (4) detachably connected to a handle (2) to enable the shaft (4) to be detached for repair or maintenance. The shaft (4) and handle (2) are detachably connected by spring-loaded latches (10) in the handle which are frictionally engageable with pins (8) projecting from the coupling face of the shaft (4). An external locking sleeve (20) prevents inadvertent separation of the shaft and handle. Illuminating light and the image to be viewed are coupled across the handle/shaft interface by abutting ends of fiber optic bundles (76, 80, 86, 92). The shaft (4) can be flexed by adjustment of manual controls on the handle as a result of racks (40, 44) in the handle (2) exerting a pushing motion on racks (50, 52) in the shaft (4), this pushing motion being transmitted into a pulling action applied to flexure wires (66, 62) extending in the shaft by virtue of pinions (54, 56) interconnecting the two racks of each pair of racks (50, 52) in the shaft (43. An alternative embodiment (Figures 14 and 15) has meshing gears on the shaft and handle to transmit across the handle/shaft interface the motion which flexes the shaft.

Abstract: METHOD OF POLYMERISING OLIGOMERS OF POLYDIORGANOSILOXANE          IN THE PRESENCE OF FILLER                           Abstract Oligomers of low molecular weight polydiorgano-siloxanes, polydiorganocyclosiloxanes, or mixtures are polymerized in the presence of acidic or neutral reinforcing fillers.  Trifluoromethane sulfonic acid is used as the polymerization catalyst.  The method can also include endblocked polydiorganosiloxane to control the molecular weight of the silicone polymer in the silicone polymer-filler produced.  The method combines the oligomer and filler, heats to from about 70 to 150°C, adds catalyst, adjusts temperature, and polymerizes the mixture, then inactivates with a Lewis base such as calcined magnesium oxide.  The non-creping silicone polymer-filler mixture which is the product of the method is usable as electrical insulation grease, or as a reinforced polymer mixture useful  in producing silicone elastomers.  The mixture can be mixed with curing agents to produce heat curable and moisture curable elastomeric compositions.

Abstract: ABSTRACT OF THE DISCLOSURE         An optical binary signal geophone is described.          The geophone utilizes an optical fiber for the transmis-sion of light to the geophone.  The geophone contains a light chopping means which oscillates in response to vibrations imparted into a geologic formation.  As the chopping means such as a baffle or a tubular member vibrates, it chops the light signal and creates an on/off light pattern.  The light passing through a slit in the baffle or tubular member is returned to the seismic vehicle for further processing.  The optical geophone creates a binary signal directly without the use of clipping electronics and magnets or coils used in conventional geophones.

Abstract: FLOW CONTROL NOZZLE AND SHUTOFF VALVE HAVING          SCREEN-CARRYING PASSAGE IN ROTATABLE STEM                          Abstract A flow control nozzle and shutoff valve has a housing which  defines  inlet  and  outlet  openings  on  opposite  sides thereof,  and  a  flow  channel  extending  therethrough  for communicating the inlet and outlet openings.  A control member is journaled by the housing for rotation about an axis that intersects  the  flow  channel.   The  control  member  has  a ball-shaped portion that is positioned along the flow channel.          An  elongate  flow passage  is  formed  through  the ball-shaped portion of the control member.   A curved,  screen-like,  flow regulating formation is positioned at one of the ends of the flow passage.  The control member is movable relative to the housing  among  first,  second  and third  control  positions  to selectively bring its flow passage into or out of alignment with the flow channel, and to selectively position the screen-like formation near the inlet and the outlet openings.   When the control member is in its first control position, the screen-like formation is held in proximity to the inlet, and the flow of fluid that issues from the outlet takes the form of a solid, non-dispersed stream.  When the control member is in its second control position, the screen-like formation is held in proximity to the outlet, and the flow of fluid that issues from the outlet is dispersed by the screen-like formation to form a spray.  When the control member is in its third control position, the control member operates to close off fluid flow through the unit.
