摘要:
An air compressor assembly can include a support structure with a compressor mechanism, at least one fluid tank, a pair of wheels, and a handle attached thereto. The air compressor assembly can be configured with the compressor mechanism having a perpendicular orientation relative to the at least one fluid tank so as to provide a relatively narrow assembly and to facilitate servicing and/or maintenance of the assembly. Furthermore, the wheels and handle can be configured so that the assembly can be relatively easily located in a balanced transport position. Additionally, an accessory support plate can be attached to the top of the assembly to serve as a dolly.

An internal combustion rotary engine comprising a housing, at least one sun wheel centered about the central axis and positioned within one of at least one cylindrical compartment of the housing, and including a sun wheel circumference and at least one semicylindrical receptable defined along the sun wheel circumference, at least one lobe extending from an inner cylindrical surface of the compartment, and at least one planet wheel received in the at least one semicylindrical receptable of the sun wheel. The at least one planet wheel may be configured to engage the inner cylindrical surface of the cylindrical compartment and include at least one indentation configured to be received by the at least one lobe when the at least one planet wheel rotates along the inner cylindrical surface. Air intake and compression as well as combustion and exhaust may be performed within the same or different compartments of the at least one cylindrical compartment.

A water heater includes a water container, a combustion chamber adjacent the, water container, a burner associated with the combustion chamber and arranged to combust fuel to heat water in the water container, a blower assembly positioned to receive combustion gases generated by the burner, a shield positioned below at least a heating portion of the burner, a diverter that directs combustion air into the combustion chamber below the shield, and a passageway that directs at least a portion of the combustion air from the combustion air inlet, as primary combustion air, to the burner.
摘要:
A heat-shrink tube for an electrical power cable comprises a sleeve having an insulating inner layer, a conductive outer layer and a thermoplastic mid-layer located between the inner and outer layers. The mid-layer is recovered by the application of heat thereto. The insulating inner layer is preferably comprised of an elastomeric material and the thermoplastic mid-layer is rigid and acts to retain the inner layer in a radially expanded state prior to its recovery.
摘要:
A mounting device includes a base having a first surface and a second opposite surface, the first surface having a supporting surface and an engaging member having an engaging surface. The engaging member can include an elongated flexible member with a headed end having the engaging surface. The mounting devices can be mounted on a surface of a substrate, e.g. an automotive transparency, to provide a panel, and the panels can be fixedly secured over an opening, e.g. an opening in the body of a vehicle, without the use of structural adhesive.
摘要:
A method for using electrical stimulation to achieve a physiological reaction in an individual using an electronic stimulation device is described. The electronic stimulation device is used to apply a waveform to the individual. The waveform includes at least a plurality of packets. Each of the plurality of packets includes a plurality of pulses. A plurality of variables associated with the waveform are controlled to provide a waveform shape for achieving the physiological reaction in the individual.

A contact safety and trigger mechanism for use with a pneumatic fastener in order to permit efficient pneumatic fastener actuation mode selection. A rotating rod is included in a contact safety assembly which is constructed to slide toward/away from a driver housing, defining a piston for securing a fastener disposed within the piston's path of travel. The rotating rod includes a first shoulder or ledge and a second shoulder which is off-set from the first shoulder. The rod may be rotated in order to orientate the selected shoulder, to function as a stop for a pivoting trigger assembly, which is constructed to contact a pneumatic valve, to initiate a fastening event in-which a fastener is driven into a workpiece. The configuration of the rotating rod permits for selection between a contact actuation mode wherein movement of the contact safety initiates securing of a fastener and a sequential actuation mode in which the trigger assembly is manipulated by a user to trigger securing of a fastener after the contact safety has be depressed towards the driver housing.
摘要:
The present invention is directed to pressure-sensitive adhesive compositions and pressure-sensitive adhesive constructions fabricated using the pressure-sensitive adhesive compositions. The pressure-sensitive adhesive compositions comprise about 10 to about 40% of a styrene-isoprene block copolymer, about 5 to about 30% of a styrene-butadiene block copolymer, about 30 to about 65% of an aromatically modified tackifying resin, about 8 to about 30% of a plasticizing oil and optionally about 0.2 to about 2% of an antioxidant, wherein the percentages are based on the total weight of the composition.
摘要:
The invention provides systems, modules, bioreactor and methods for the automated culture, proliferation, differentiation, production and maintenance of tissue engineered products. In one aspect is an automated tissue engineering system comprising a housing, at least one bioreactor supported by the housing, the bioreactor facilitating physiological cellular functions and/or the generation of one or more tissue constructs from cell and/or tissue sources. A fluid containment system is supported by the housing and is in fluid communication with the bioreactor. One or more sensors are associated with one or more of the housing, bioreactor or fluid containment system for monitoring parameters related to the physiological cellular functions and/or generation of tissue constructs; and a microprocessor linked to one or more of the sensors. The systems, methods and products of the invention find use in various clinical and laboratory settings.
