A helmet has shell with a front opening covered by a faceguard of elongated wire segments. Loopstraps engage around wire segments at sides and a crown of the shell and fasteners connect the loopstraps to the shell. The fasteners each have a nut extending from an inside of the helmet shell out into a hole of the shell and an aperture of the loopstrap, and a stud removably connected to the nut by pushing and turning the stud by about a quarter turn to lock the stud to the nut. A tension spring between a head of the stud and the loopstrap urges the stud away from the nut when the stud is rotated to unlock the stud for facilitating a quick removal of the stud from the nut and a quick disconnection of the loopstrap and faceguard from the helmet shell.

A knee pad construction includes a shaped cushion element with a concave interior with a recess having a flowable gel insert therein. The recess and insert are shaped to accommodate the left knee or the right knee of an individual.

A multi-parametric vital signs monitoring device configured for use as an ambulatory and a bedside monitor wherein the device can be patient-wearable and is battery powered. The monitoring device can be used with a charging cradle to provide power to the device in lieu of the battery as a power source for bedside applications, in which the cradle further serves as an intermediary device to enable a data link with a PC or other peripheral device. The monitoring device can include a wireless radio to enable bi-directional transfer of patient-related data to a separate remote station.

A ball joint, is provided in the form of a cross axis joint with a housing, a bearing shell in the housing and a ball sleeve. The ball sleeve includes a ball portion with a bearing surface cooperating with the bearing shell and a first pivot pin and a second pivot pin extending from said ball portion in an axial direction. The ball sleeve has an inner surface defining a through hole (50) for receipt of a connection bolt. The first pivot pin has a first end with a first outer surface (42) and a first annular end face (41) and the second pivot pin has a second end with a second outer surface (44) and a second annular end face (43). Sealing rings (60, 60′, 60″, 90, 95) are provided, each having a first axially extending portion extending along the first outer surface and having a sealing area outer surface defining a bellows seal seat (64, 98) and a radially extending portion extending along the end face. Each bellows seal (52, 54) is connected to the housing at one end and connected to said bellows seal seat (64, 98) at another end.

A mechanical load bearing indicator producing signals to a user when the user applies more than selected amounts of load between an extremity of the use and a surface. The indicator has a base plate adapted to establish a frame of reference with the surface, a load plate mounted for movement toward and away from the base plate and adapted to receive loads from the user's extremity, and at least two snap domes mechanically engaged between the base plate and the load plate for generating two signals when more than two different respective loads are applied to the load plate by the extremity. The domes are either in series between the plates or are together in a dual dome containing both, or are one or more stacks of domes which individually collapse under incremental loads which are added together to form the selected lower and higher loads.

A support frame for a suspension device includes a plurality of leg members attached at their upper portion to a mounting plate. The mounting plate has pivot members and circumferential openings for connecting the leg members. There are also height adjustment members as well as a number of optional features to facilitate use of the suspension framework.

The invention provides a method and apparatus for separating a stack of folded sheets by inserting a first, second, third and fourth count fingers into four successive openings in the stack, and separating the stack between the second and third count fingers. Where separation is carried out after a desired number of folded sheets have passed the third count finger, a completed pack having the desired number of sheets may be formed downstream from the third count finger. The count fingers may be operatively mounted in count finger cassettes.

An improved wet scrubber tray provides increased resistance to vibration-induced cracking. The tray is self supporting to eliminate wastage of raw material, and additional internal stiffeners added to the tray make multiple intermediate stiffeners. The connection of the intermediate stiffeners to the perforated bottom plate is changed to eliminate the shop weld in the bottom plate. The holes in the perforated bottom plate are repositioned so that they are moved away from the boundaries of the tray to reduce their influence on boundary conditions. The thickness of the tray material may be increased to lower the vibratory stresses. The mechanism for holding the trays themselves within the spray absorber tower is changed so that the trays are now held down by plate material that is attached to the support grid, but not to the trays. Three field welds are applied to the sides of each tray to hold the trays in place relative to each other and are strategically placed to allow adjacent side stiffeners to act together as a composite section, thus increasing their strength. Elastomeric material such as neoprene is used at the tray-to-grid attachments to increase the damping of the system. Formed features in the trays such as single or multiple ribs, bosses, domes or dimples may also be provided to increase tray stiffness or influence wet scrubber performance.
