Abstract: A housing for mounting on a water dispenser which includes a compartment to extend over water dispensing spigots on the dispenser. The compartment has an aperture in its top in which presser bars are positioned. The presser bars are pivotally supported by the housing and overlie the spigots to actuate them in a manner to reduce wear on and corresponding leakage of their valves. The presser bars have large areas of contact to enable them to be depressed by persons of reduced finger strength by forming a leverage system which reduces the actuating force necessary to operate the spigots.

Abstract: An elongate flexible vacuum tube including an inner porous liner of intertwined flexible fibers of nylon or the like connectable between a vacuum source and the interior of a flexible vacuum bag covering a part formed of uncured thermosetting resin, or of superposed sections or laminae with thermosetting adhesive therebetween, under an overlying porous breather pad of intertwined fibers. An end of the liner can be positioned in intimate contact with the breather pad to form a vacuum path therewith so that a vacuum can be pulled on the part from a vacuum source, through the porous liner and breather pad, while it is being cured in an autoclave.

Abstract: A resilient pad of intertwined nylon fibers of minute cross-sectional diameter having minute interstices throughout. The pad serves as a breather for the curing of a part of composite resinous material for which purpose it is placed over the part, which part is, in turn, fitted onto a shaped tool. To effectuate curing of the part, the part and breather pad are covered by a vacuum bag which is, in turn, sealed around its edges to the shaped tool and provided with a vacuum outlet. The whole assembly is then placed in an autoclave, wherein it is subjected to heat and pressure while vacuum is applied to the vacuum bag to evacuate air and volatile effluents from the part through the breather pad while the part is being cured under the influence of heat and pressure.

Abstract: A lock having a counterweight connected through a lever to a spring-actuated lock bolt on a safe to balance out any inertial forces tending to move the bolt out of its locking position when the safe is struck a heavy blow. A latch forming a part of the lock latches the bolt in its locking position when an attempt is made to dislodge or destroy the lock case or a part thereof. A selectively usable bolt part is effective to change the lock from a deadbolt type to a slam-bolt type.

Abstract: Branched-chain diols and a method of forming them by reacting 1,4-diiodoperfluorobutane and perfluoropropylene to obtain branched-chain diiodide adducts thereof, reacting the diiodide adducts with ethylene to obtain I--CH.sub.2 CH.sub.2 --R--CH.sub.2 CH.sub.2 --I, wherein R is a branched-chain perfluoroalkyl radical, and hydrolysing the iodo groups to alcohols to obtain HO--CH.sub.2 CH.sub.2 --R--CH.sub.2 CH.sub.2 --OH. These diols can be reacted with branched-chain diisocyanates to form polyurethanes of better processability and lower glass transition temperatures than polyurethanes prepared from linear fluorinated monomers.

Abstract: A noiseless fan having a group of parallel and thin, closely spaced disks rotatable at relatively high speed. As the disks rotate, boundary layers of air on the disk surfaces rotate bodies of air between the disks while centrifugal force developed by the rotating disks drives the air radially outward to be expelled into the atomosphere. Intake air is admitted axially through central openings in the disks and is directed radially outward into the spaces between the disks to displace the expelled air.

Abstract: A cooling fan positioned within the casing of an electric motor comprising a plurality of closely spaced frusto-conical disks carried by the motor shaft which draw intake air past the motor rotor and stator when they are rotated. Bodies of air between the rotating disks are then thrown radially outward by centrifugal force and directed to exhaust vents formed in the casing.

Abstract: A motor driven fan having a plurality of annular disks carried by a drive shaft of the motor in closely spaced, parallel relationship. At relatively high motor speeds, bodies of air between the disks are sheared from boundary layers of the air adhering to the sides of the disks and expelled radially outward by centrifugal force acting on them. An annular plate carried by the disk assembly has a cylindrical skirt encircling the disk peripheries which deflects air expelled from between the disks toward the motor to cool it.
