Abstract: An electrosurgical system includes an electrosurgical instrument having an electrode with a polymeric dielectric coating; and an electrosurgical generator, which includes a power converter configured to generate RF energy; a sensor coupled to the power converter and configured to sense a parameter of the RF energy; and a controller coupled to the sensor and the power converter. The controller is configured to control the power converter to output an RF waveform to achieve conductor breakthrough through the polymeric dielectric coating. The controller is further configured to determine whether the conductor breakthrough occurred based on the parameter; and execute a treatment algorithm based on a determination of the conductor breakthrough.

Abstract: Jaw members of end effector assemblies include sealing plates configured to direct the amount and flow of energy through the sealing plates. The sealing plates may have a height varying from a minimal height to a maximum height along a width or a length of the sealing plate and/or a sealing surface including at least two impedance zones having different impedance values.

Abstract: A cover assembly for a grounding arrangement having a ground stud electrically connected to a conductive surface. The cover assembly includes a cable boot configured to enclose at least a part of the ground stud and the conductive surface. The cable boot has an aperture. The cover assembly further includes a plug boot is insertable into the aperture of the cable boot. The plug boot includes a stud receiving portion defining an interior space. At least a portion of the ground stud is received in the interior space when the plug boot is inserted into the aperture. A handle portion extends from the stud receiving portion.

Abstract: A base for a bed comprising (preferably two or four) light-weight thermoplastics platforms interlocked together by couplings which engage skirts and lugs depending from the platforms so as to prevent rotation of one platform relative to another. The platforms are easily separated for transport by a vertical lifting force yet they resist separation by unintentional rotational forces caused by sitting on or lifting their peripheral edges.

Abstract: Athletic foot apparel essentially in the form of a sock includes portions adapted to provide muscular support to the calf and ankle and a padded bottom portion for effectively absorbing shocks imparted to the foot during athletic activity. The ankle and calf portions include a layer of elastic material with the elastic material of the ankle portion being spaced from the elastic material of the ankle portion. Each layer of elastic material is disposed between inner and outer layers of fabric material. The padded bottom portion is secured to the sock and may be comprised of latex.

Abstract: An open-mouth container having a mouth which partially undercuts the body of the container yet which can be shaped about a simple core.

Abstract: Large containers are injection moulded or vacuum formed around a framework which becomes part of the final article. This gives good strength and rigidity.

Abstract: A visual or audible indicator to indicate the absence of an additive ordinarily added to the rinse or wash water of a commercial dishwashing machine is disclosed. The dishwashing machine includes a separate reservoir containing an additive, a supply line connecting the reservoir to the point within the dishwashing machine where the additive is normally added, and a pump in the supply line for pumping the additive from the reservoir through the supply line. The pump includes a check-valve for retaining the additive in the supply line when the pump is not pumping. The indicator includes a vacuum operated switch and a connecting line connecting the vacuum operated switch to the supply line between the additive reservoir and the pump. The pump, switch, and connecting line are physically located above the maximum possible level of additive within the additive reservoir.

Abstract: A light-weight base for a bed is described which includes a mattress-supporting platform (4) supported on a frame (1) of opposed ribs (2) in which the platform (4) is formed from an array of resiliently depressible crested thermoplastics bridges (5) which act as springs and which extend between pairs of opposed ribs (2) and their crests rise above the tops of ribs (2). Bridges (5) may be conveniently injection molded from crystalline polypropylene or propylene/ethylene copolymer in sections 0.5 to 5 mm thick and are preferably integral with fixing means (6) which make push fits into ribs (2). The polypropylene bridges have good resistance to flexing fatigue, are light-weight and, when provided with integral fixing means, are easily assembled on frame (1). These modified bases may be used as seat or back portions of chairs as well.

Abstract: An adjustable recline-control mechanism for furniture of the type comprising a carrier for an occupant, e.g. a seat-pan and a support e.g. a back-rest, reclinable relative to the carrier wherein the angle of recline is controlled by the mechanism which comprises a link one end of which is pivotally connected to the support while the other end is latchable by at least two co-operating latching portions which respectively prevent travel of the link in opposite directions, the respective latching portions being spaced apart relative to the pivot axis of the link such that a jolt to the front or back of the support exerts on the link a moment which biasses the link towards latching irrespective of the direction of the jolt.
