Title: Method and apparatus for sidewall bulge and valley detection
Inventor: ENGEL JEAN EDOUARD
IPC: B29D30/00
Filed: 1982-05-19
Abstract: A method and apparatus (10) for determining the presence of bulges and valleys in the sidewall of a tire (12). Displacement transducers (16-20) monitor deflections in the sidewalls of the tire (12) and provide output signals characteristic of such deflections. A differentiator (38) determines the slope of such deflections and, for such periods that the output of the differentiator (38) exceeds particular thresholds (40a,40b), integrators (42a,42b) integrate the output. The maximum integrated values sensed about the tire (12) are stored (44a,44b) and displayed (46a,46b).

Title: Inhalation actuated dispensing apparatus
Inventor: BLASNIK WILLIAM
IPC: A61M15/00
Filed: 1991-12-10
Abstract: Movement of the cover (B) relative to the housing (A) spring loads and latches a piston carrier (38) in the armed position. Inhalation causes a passageway door (14) to open, releasing the carrier latch (52) to permit the carrier to be moved toward the canister 18 by the spring 42. The piston 34 moves with the carrier 38, due to a fluid connection therebetween, applying a compression force on the spring loaded canister valve stem 32 and causing it to dispense the inhalant through an opening in the piston which functions as a nozzle. After the inhalant is dispensed, the carrier fluid vents permitting the spring of the canister valve stem to move the piston relative to the carrier, and thus release the force applied to the valve stem by the piston. The sensitivity of the toggle linkage between the door and the carrier latch is adjustable. The linkage can be manually tripped for testing purposes. <IMAGE>

Title: Electropipettor and compensation means for electrophoretic bias.
Inventor: PARCE J WALLACE
IPC: F04B17/00
Filed: 1997-06-27
Abstract: The present invention provides for techniques for transporting materials using electrokinetic forces through the channels of a microfluidic system. The subject materials are transported in regions of high ionic concentration, next to spacer material regions of high ionic concentration, which are separated by spacer material regions of low ionic concentration. Such arrangements allow the materials to remain localized for the transport transit time to avoid mixing of the materials. Using these techniques, an electropipettor which is compatible with the microfluidic system is created so that materials can be easily introduced into the microfluidic system. The present invention also compensates for electrophoretic bias as materials are transported through the channels of the microfluidic system by splitting a channel into portions with positive and negative surface charges and a third electrode between the two portions, or by diffusion of the electrophoresing materials after transport along a channel. <IMAGE>

Title: System for the control of temperature and humidity within a greenhouse
IPC: A01G9/24
Filed: 1980-04-15
Granted: 1984-02-15
Abstract: A system for the control of temperature and humidity in a greenhouse relies on a heat pump and various sensors for the measurement of temperature and relative humidity both inside and outside the greenhouse. Conditions inside and outside the greenhouse are analysed to fail within a particular class and the classes of weather conditions are matched to provide an appropriate control strategy for the greenhouse. The purpose of the invention is to provide for the optimisation of the extraction of useful heat by means of refrigerative de-humidification of the greenhouse and to utilise this heat to minimise the amount of supplementary heat required for the greenhouse, or as a heat source for other heating purposes. It is also the purpose of the invention to provide for the optimisation of the extraction of purified (distilled) water from water supplied to the plants.

Title: A driving device for a stepping motor
IPC: G04C3/14
Filed: 1981-12-04
Granted: 1984-04-18
Abstract: A driving device of a stepping motor comprises a driver/detector circuit for detecting whether a rotor has rotated or not by comparing a voltage induced across a driving coil by the free oscillation of the rotor with a reference voltage after a driving pulse is cut off and a control circuit automatically varies the pulse width of the driving pulse in response to an output of the driver/detector circuit. The control circuit includes circuitry for lowering the reference voltage when the pulse width of the driving pulse is lengthened thereby enabling use of a wider range of driving pulse widths than would otherwise be possible.
