  • Patent number: 10683041
    Abstract: A mud flap lifting system specifically for a live bottom type trailer vehicle in which asphalt or similar is dispensed from the rear of the trailer load box for a paving operation using a paving machine in tandem with the trailer. Pneumatic lift cylinders on each side of the trailer load box are used to retract and extend cables running rearwardly from the cylinders to and through cable guides positioned vertically above the mud flaps. The cables are operable to pull or lift the lower portions of the mud flaps upwardly and outwardly into curved configurations located above a paving machine roller as it engages the rear wheels of the trailer, and at a height designed to engage the paving machine hopper as it engages the trailer.

  • Publication number: 20100113984
    Abstract: In vivo biocompatible hydrogels to couple and transmit high intensity ultrasound for hemostasis and ablation during surgery, the hydrogels having 4-40 wt. % of a polymer comprising acrylates and the balance water. A group of hydrogels based on cross-linked methacrylate one of which is polyethyleneglycol methacrylate, can form rigid, low acoustic attenuation coupling members and are in vivo biocompatible. These coupling members consist of hydrogel formulations having mechanical and acoustic properties such that ultrasound transmission standoff members of various dimensions and structural configurations function as efficient ultrasound transmission media and devices within which the ultrasound beam can be transferred to a focal point at the end of the standoff or in close proximity to it.

  • Patent number: 6866630
    Abstract: A medical ultrasound coupling media and lubricant, in gel or liquid form, comprised of polyethylene oxide (PEO), and aqueous solvent solutions. The inventive coupling media provides long term biocompatibility (bio-inert, bio-erodable or biodegraded and excreted) in vivo with human tissue and body fluids. The ultrasound coupling and lubricating media is formulated and manufactured in such manner and form that renders the acoustic media sterile, non-cross-linked, pseudoplastic, and containing acceptably low levels of pyrogens.

  • Patent number: 6846291
    Abstract: Method and formulations to extend the utility of ultrasound compliant adhesive hydrogel membranes from static to dynamic applications by modifying the surface of at least one face so as to transform the tactile nature of the surface from one that is adhesive and render it smooth and lubricious. Such modification thus provides one face that is smooth and lubricious and the other unmodified, hence providing one adhesive surface that can be attached to the skin of a patient, the face of an ultrasound probe or other surfaces that benefit from the adhesive/lubricious configuration of such modified adhesive hydrogels.

  • Patent number: 6776757
    Abstract: A medical ultrasound coupling media and lubricant, in gel or liquid form, comprised of polyethylene oxide (PEO), at least one of polyalkylene glycols and polyhydric alcohols, and the balance water. The inventive coupling media provides long-term biocompatibility (bio-inert, bio-erodable or biodegraded and excreted) in vivo with human tissue and body fluids. The ultrasound coupling and lubricating media is formulated and manufactured in such manner and form that produces higher viscosity gels with decreased amounts of polymer and renders the acoustic media sterile, non-cross-linked, pseudoplastic, and containing acceptably low levels of pyrogens.

  • Patent number: 5481811
    Abstract: A modular system for the support and positioning of a workpiece for use with a device such as an inspection system. The system includes a base having a plurality of exterior faces, at least some of which have an array of equally spaced holes forming a grid pattern. At least one riser is attached to the base cube by a fastener, which can be inserted into the riser by defeating an outwardly biased locking member at the inner end of the fastener, extending through said riser and into the holes of the base cube. The fastener is used to provide positive location and fastening of the risers to the base cube. Functions of individual risers include support, clamping, datum point positioning and providing reference points.

  • Patent number: 5146127
    Abstract: Windingless rotor, variable reluctance, field excited, eletromechanical machines that provide for a family of windingless rotor machines consisting of both line commutated, synchronous machines, and self-commutated or self-synchronous machines, in both rotary and linear format. The basic operational format of this group of machines is a combination of an interdependent working relationship between the geometric parameters of the stator and rotor poles, and specially contoured pole surfaces and tips, all working in a complementary relationship to provide magnetically workable, variable reluctance air gaps that are capable of controlling the alternating magnetic flux waveform to effect a viable and efficient energy conversion process at substantially the fundamental frequency component, which is also the synchronous frequency of operation of the machine.
