Abstract: A firefighter's garment as disclosed herein may be a coat or trousers or a vest. The garment has an outer layer, an intermediate layer, and an inner layer. A spacer element or elements are positioned between two of the layers of the garment. The spacer element or elements in the firefighter's garment establish and maintain an air space or air spaces between the layers of the garment, even when localized pressure or weight is applied to portions of the garment. Thus, the firefighter's garment has excellent heat insulation qualities without being heavy and/or bulky. Thus, a firefighter wearing the garment is continually protected and is subject to minimum stress and is able to work more effectively than a firefighter wearing a firefighter's conventional garment.

The hood includes a front bib for protecting the neck of the wearer and which includes tabs of fastener material for attachment to the outer collar portion. The hood may be carried on the back of the coat when not worn, or removed from the coat entirely, wherein the strips of fastener material on the inner and outer collar portions join the collar portions together to make a complete collar for the coat.

Abstract: A protective garment incorporating radiation resistant materials has a resilient support for conforming to and supporting the weight of the garment across the back of the wearer. The support is a wide resilient band having a first end connected at a first interior side seam and a second end connected at a second interior side seam for extending across an interior back panel surface of the garment. When stretched across the back, the garment weight is distributed uniformly across the back to reduce fatigue. Alternatively, the garment may have a pair of resilient straps which extend from the shoulder seams and sides of a front panel, across the back to the front of the garment. By providing resilient back panels which extend from the shoulders, the front panel weight is distributed over the shoulders and back. Utilizing such a protective garment reduces upper body fatigue for those required to wear such garments.

Abstract: The present invention provides a one-piece, open-seam garment which encompasses the head, covers and conforms to the body and limbs of the wearer, and provides on-demand access to one portion of the covered body and limbs without uncovering the remainder of the body and legs. When worn, the garment provides privacy and protection for the person unlike the conventionally used johnnies and hospital gowns conventionally worn during physical examination or medical treatment in the physician's office or clinic.

Abstract: One aspect of the invention is a cooling pillow comprising a flexible pouch and thermal transfer fluid composition hermetically filled in the pouch. A second aspect of the invention is a cooling device which comprises a pad having a flexible pouch and a thermal transfer fluid composition hermetically filled in the pouch, and means for holding the pad therewith to bring the pad in contact with the human body. The fluid composition comprises a mixture of fine particles of hard or graphitic carbon having good thermal conductivity and water.

Since the carbon particles have good thermal conductivity, the fluid readily reaches a temperature close to ambient temperatures and can gently cool the human body. Long use allows the body to be continuously cooled down to a temperature close to the ambient temperature.

Abstract: Laboratory-scale dyeing of samples of lengths of material must correspond to the continuous process conditions as executed in practice in order to obtain comparable dyeing results. For this purpose, the provision is made of joining the sample piece into a tube and of pushing same onto a roll which revolves continuously during dyestuff application as well as during the steaming procedure. For performing this laboratory dyeing-steaming cycle, it is advantageous to arrange the dyeing roll on a rocking lever pivotable from i dyeing position below the dyestuff applicator into a steaming position below a steamer hood. The steamer hood, for steaming purposes, need merely be moved downwards to immerse the dyeing roller in total into the steam atmosphere.

Abstract: The present invention is a unique semi-automatic mop wringer. The mop wringer comprises a hollow housing vertically movably supported on a supporting structure by a suspension mechanism. The housing is engaged with the supporting structure through a rack-and-gear mechanism, so that a downward motion of the housing can be transmitted into the rotation of crank members which in turn drive a wringer roller to squeeze the mop against a wringer plate mounted inside the housing. A user can use the present invention mop wringer to wring a mop by placing the mop inside the housing, holding the mop holder and applying a downward force. The downward motion of the housing causes the wringer roller to move in a circular path to squeeze the mop against the wringer plate. When the user withdraws the downward force, the housing moves back upwardly to allow the user to repeat the process.

Abstract: A remote control system for actuating a central vacuum system from a remote location such as a vacuum cleaning hose handle without the use of a separate, dedicated system of control wires.
