Title: Process for the production of polyisoolefins
Inventor: BAADE WOLFGANG
IPC: C08F4/00
Filed: 1995-08-04
Abstract: Polyisoolefins are produced according to the invention by polymerising isoolefins having 4 to 16 carbon atoms, optionally with conjugated diolefins having 4 to 6 carbon atoms and/or cationically polymerisable, mono- or polyunsaturated, organic compounds having 4 to 16 carbon atoms in the presence of mixtures of carbon dioxide and linear, branched and/or cyclic C4-C8 alkanes and in the presence of catalysts at temperatures of -70°C to +20°C and pressures of 1 to 70 bar, wherein the weight ratio of carbon dioxide to alkanes is 10:90 to 90:10.

Patent CA-2158897-A1 (CA)
Title: Survey tool for email
Inventor: SANDERS JAMES B
IPC: G06Q30/00
Filed: 1995-09-22
Abstract: The present invention provides a survey tool for use with an electronic mail (email) system implemented in a computer network having a plurality of nodes interconnecting a corresponding plurality of computers. In the preferred embodiment the survey tool includes three modules; a builder module for composing a survey, an answer module for responding to the survey, and a collector module for generating survey results. The builder module provides a graphical interface for generating a graphical survey. The survey is then encoded in a survey description language (SDL). Next, the builder module attaches the SDL encoded survey to a survey email together with the email headers, and transmits the survey email to one or more targeted users via the computer network. The targeted user retrieves the survey email and attempts to invoke the answer module. If a copy of the answer module cannot be located at the receiving computer a copy of the answer module can be transferred from a remote location via the computer network. Upon execution of the answer module, graphical prompts are generate for the targeted user. In turn, the targeted user provides appropriate survey response which are recorded by the answer module. The survey response is then encoded into a survey result language (SRL), attached to an answer email and transmitted to a survey cache of the computer network. Finally, the collector module accesses the survey cache and retrieve the SRL survey response(s). The SRL encoded survey responses are decoded, interpreted and tabulated. Appropriate graphical displays and/or reports can then be generated.

Title: Process for controlling or regulating the pressure of a press for separating solids and liquids
Inventor: HARTMANN EDUARD
IPC: B01D33/04
Filed: 1995-02-15
Abstract: In discontinuously functioning filter presses (1), a further increase of the pressing pressure is limited based on the course over time of the discharge behavior of the pressed-out liquid.  The limiting times are determined with a process regulator (24) as those times at which momentary or average discharge capacities or discharge accelerations reach maximal values.       Troublesome predeterminations of desired or empirical values can thus be avoided.  The press operates in a process of self-optimization to the pressing pressures and to the times to which the pressure increase has to be limited, in view of the actual process parameters and objectives that are involved.
Patent CA-2161996-A1 (CA)
Title: Internal Pipe Cutter
Inventor: OBST NORMAN
IPC: B26D1/60
Filed: 1995-11-03
Abstract: A device for cutting pipe internally includes an annular cutter head having a plurality of circumferentially spaced openings therethrough, a stepped drive shaft extending from the cutter head and having a longitudinal bore therethrough and an adapter at the distal end of the drive shaft for connection to a rotary drive member.  A frustoconical mandrel has a threaded rod extending from one end thereof through the shaft bore to the distal end of the shaft where it threadably engages a nut held stationary with respect to the drive shaft. The mandrel  has  a  plurality  of  inverted  T-shaped  slots extending along the frustoconical side thereof,  each slot receiving the T-shaped projection on a cutter body.   Each cutter body has a rotatable cutter wheel mounted thereon, the wheel being adapted to project through a corresponding opening in the cutter head.  With the components assembled together, rotation of the drive shaft by the rotary drive member will cause rotation of the mandrel and the threaded rod.   The relative movement between the threaded rod and the nut causes the rod to move through the nut so as to draw the mandrel into the cutter head.  Due to the sloping nature of the mandrel wall and the interengagement between the T-shaped slots and projections the cutter bodies and the cutter wheels will be moved progressively radially outwards of the cutter head during rotation of the drive shaft so that the cutter wheels can cut into the internal wall of the pipe at a controlled progressive rate.

Patent CA-2164409-A1 (CA)
Inventor: BEARD DAVID LEWIS
IPC: H04B17/00
Filed: 1994-05-30
Abstract: A fading simulator for generating multipath-faded test signals which have attenuation notches of precisely controllable frequency position and attenuation depth from a modulated input signal of known bandwith. The input signal is fed to a splitter (10) that directs two in-phase components to a first path (14) and a second path (18). The input to each path is divided by a splitter (22) into in-phase and quadrature sub-signals (24 and 26) having a quadrature phase relationship, each sub-signal being fed to a respective inverting attenuator (28 and 32), the outputs of the attenuators then being combined in a combiner (36) and the combined output being passed through a variable delay line (16) to generate the output of the respective path. The outputs of each path are then combined in a combiner circuit (12) to generate the multipath-faded faded test signal. All four inverting attenuators are preferably substantially identical to one another so that the two paths have close to identical temperature-drift and other characteristics. The attenuators and delay lines are electronically controlled in tandem, preferably using a microprocessor and stored program, to generate precision, static or dynamic, attenuation notches desired.

Title: Modular Spill Deck
Inventor: FORNEY FRANK G
IPC: A61Q5/02
Filed: 1996-04-24
Abstract: A spill deck module of the present invention includes a substantially planar bottom wall, a pair of opposing side walls and a pair of opposing end walls which form an interior chamber.  Each side wall and end wall includes an aperture allowing fluid communication between adjacent modules.  Initially, the side wall and end wall apertures  are closed by a removable sealing assembly.  When a number of modules are desired to be arranged to form a composite spill deck, the sealing assemblies in adjacent modules are removed and replaced with module connection assemblies allowing fluid transfer between adjacent modules.  A deck grating either rests on the bottom surface of the spill deck or rests on top of ribs provided in each module.  The grating forms a continuous spill deck for support of containers of hazardous or non-harzadous liquid materials in various configurations using different combinations of the spill decks.
