Described is a parallel batch reactor for effecting chemical reactions. The parallel batch reactor includes a plurality of reactor vessels for receiving components of a reaction, an inlet port for receiving pressurized fluid, and a plurality of valves configured to transfer fluid from the inlet port to the reactor vessels and fluidically isolate one or more of the reactor vessels from at least one of the other reactor vessels. The reactor further includes a pressure monitoring system comprising an array of pressure sensors configured to sense pressure in the reactor vessels. Each of the pressure sensors is aligned with one of the plurality of reactor vessels and located external to the reactor vessels and fluid passageways in fluid communication with the reactor vessels.

Parallel batch reactor with pressure monitoring

In one embodiment, a parallel batch reactor generally includes a plurality of reactor vessels and a plurality of valves configured to allow flow into the reactor vessels when a gas is supplied to the reactor at a pressure higher than a pressure within the reactor vessels and restrict flow from the reactor vessels. A method includes inserting chemical components into the reactor vessels, supplying a first gas to the reactor vessels to pressurize the reactor vessels, stopping supply of the first gas, and supplying a second gas to the reactor at a lower pressure than a pressure within the reactor vessels. The second gas passes through the valves and into the reactor vessels when the pressure within the reactor vessels drops below the pressure of the second gas.

Fluid monitoring methods, systems and apparatus are disclosed, including a portable subassembly that is in electrical communication with a sensor in contact with the fluid being monitred. Preferred embodiments for the sensor include one or more flexural resonator sensing elements. In preferred embodiments the sensor subassembly is ported to multiple fluidic systems to monitor the fluid properties in an effecient manner.

Portable fluid sensing device and method

A sensor for sensing one or more properties of a vehicle fluid has a tuning fork resonator adapted to contact the fluid. The tuning fork resonator comprises two tines and is operable to oscillate so that the two tines move in opposite phase at a frequency of less than 1 MHz while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. In another aspect, a sensor includes a substrate and a flexural resonator on the substrate and adapted to contact the fluid. Circuitry for operation of the resonator is on the substrate. The resonator is adapted to receive an input signal and to oscillate while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. One suitable application for the invention is monitoring the condition of a vehicle engine oil.

A roulette playing machine which is designed for an individual player with the use of a single circulating playing ball. The machine comprises: an enclosed casing; a roulette wheel rotationally installed in the aforementioned casing and closed from above with a transparent cover that allows observation of the game but prevents physical contact with the playing ball; a drive mechanism for rotating the wheel that can be disengaged from the wheel to put it into free rotation after acceleration of the wheel, the wheel having circumferentially-arranged recesses for the playing balls and the inclined surface that ensures falling of the ball into one of the recesses when the wheel stops; electromagnetic mechanism for launching the ball in the direction of rotation of the wheel into a space between the wheel and the transparent cover; an electromechanical ball returning mechanism for returning the ball to the launching mechanism by means of an electromagnet and a lever system upon completion of one playing cycle; and a CPU that controls the operation of aforementioned mechanisms in accordance with the program. The apparatus also contains a sensor that immediately cancels the game cycle if the housing of the apparatus is intentionally or accidentally shaken to the extent that may change the game result. The invention also relates to a game based on the use of the aforementioned apparatus. The apparatus may be used in different modes with mechanical rotation of the roulette wheel or electronic simulation of the wheel on the display screen. The apparatus may standby in an attraction mode which is switched over to a game mode after loading money into a bill validator or a coin acceptor.

Curemeter and method in which UV exposure is monitored by a portable data collection module and data from the module is processed by a docking station which is located remotely from the site where the UV radiation is present. Temperature is also monitored at the data collection module, and the UV exposure data is compensated for variations in temperature. The data collection module includes shielding and filters to protect the UV detector from the harsh environment in which the UV readings are taken and to limit the radiation impinging upon the detector to the desired spectrum. Programmable thresholds for the detector signals protect against the collection of spurious data.

A mirror (10) with a pair of vertical dazzle light attenuation zones (24 and 26). Each zone consists of stripes (24a, 24b, . . . 24n, 26a, 26b, . . . 26n) capable of dynamically adjusting the widths and the attenuation intensity of the attenuation zones (24 and 26). The mirror (10) has a multi-layered structure containing a liquid crystal (32). The positions and widths of the stripes are controlled manually via adjustment pushbuttons (20 and 22), or automatically, in response to the intensity of the incident light. When a driver sees during night driving the reflection of the dazzling light in the non-attenuated areas of the mirror, the driver's head is slightly moved, or the driver manually shifts by pushbuttons (20 and 22) the groups of the attenuated stripes (24 and 26) to the position where the dazzling light (L) will be covered by these stripes. The localized attenuation of the mirror's surface will not disturb the overall view observed by the driver through the rearview mirror (10).
