  • Patent number: 3951228
    Abstract: Noise reduction enclosure for enclosing a sound-producing machine, including interconnected upstanding side walls and a ceiling at the upper ends of the side walls, wherein the side walls and ceiling are constructed of beams and support members having sheet metal panels floatingly mounted thereon. Resilient sealing members are mounted on the periphery of the sheet metal panels to isolate the panels from the beams and support members and to prevent noise leaks. Resilient grommets coact with fasteners to isolate the fasteners from the panels and to fix spacing between the panels and beams or support members, thus controlling proper compression of resilient sealing members. Openings are provided in the side walls of the panels and doors coact with the openings to provide access to the machine. The doors and doorways are arranged such that about ninety percent of the machine is available for servicing when the doors are in open position.

  • Patent number: 3949487
    Abstract: A portable hair dryer of the hard hat type having the general configuration of an articulated, collapsible "Z." The head assembly and a base are pivotally mounted at the ends of a head mounting assembly on parallel, horizontal axes so that the base and the head assembly can be pivoted to nest the base and head mounting assembly within the head assembly. Electrical cord retaining means are provided on that portion of the head mounting assembly, the middle element in the hinged "Z," which is exposed to the head space within the head assembly when the dryer is in the collapsed or nested storage condition, and the cord is introduced to the dryer through that same portion. The cord can therefore be stored out of the way within the head assembly, without interfering with pivot hinges, or with moving surfaces which are closely spaced apart during nesting.

  • Patent number: 3946498
    Abstract: A portable hair dryer comprises a flexible bonnet, a combined blower and heater power module for supplying heated air under pressure to the bonnet, and a control module for selecting the operating mode of the dryer. The power module is suspended against the back of the user by means of a pair of support straps which extend over the user's shoulders to the control module. By balancing the weights of the power and control modules, a stable condition is obtained which enables the user to perform other activities during the drying operation. The power cord of the dryer depends from the control module to assist in balancing the weights, and flexible electrical conductors in one of the support straps convey electrical power to the power module. The other support strap is removably attached to the control module to facilitate setting up and taking down the appliance.

  • Patent number: 3942575
    Abstract: Portable tire changing apparatus and method for mounting and demounting heavy tire duty tires on a wheel including a hydraulic cylinder having removable shoes for mounting and demounting, respectively. The cylinder is removably fastened to and retained by additional mounting and demounting structures, both of which are compact and anchorable to a wheel hub eliminating the necessity of affixing a wheel and tire assembly to a bulky stand. The mounting and demounting structures utilize wheel hub rigidity as a base to retain differing supporting mechanisms which position the cylinder enabling the attached respective shoe to maneuver the tire beads away from and over a wheel rim flange.

  • Patent number: 3941254
    Abstract: Air hose couplings for railway cars are prevented from uncoupling by wire form locking means reacting between the body of one coupling and the lip of the other coupling. In certain embodiments a wire form is an integral part of the air hose coupling assembly and has a laterally extending arm for manual unlocking. In another embodiment a detachable bifurcated wire form is applied to coupled air hose couplings after a train is made up and may be discarded when the respective cars are uncoupled. Alternatively, the detachable wire form also can be mounted on the clamp that secures the air hose to the coupling, or on a clamp that fits over the hose clamp, or mounted directly on the main body portion of a coupling.

  • Patent number: 3939554
    Abstract: A surface thermocouple assembly including a metal sheath having thermocouple conductors extending therethrough in spaced relation from each other and from the sheath by electrical insulating material, an opening in the sheath wall at the hot junction end and through which the conductors are extended, a ceramic plug receiving the conductors and mounted in the opening, a fusion weld of the conductors outside the plug, and a V-shaped pad with a knife-shaped edge integrally formed at the junction end. The thermocouple is made from a length of sheathed thermocouple conductors by forming a keyhole slot at the junction end, removing the insulation around the conductors, bending the conductors through the opening of the keyhole slot, mounting a ceramic plug in place, fusion welding the ends of the conductors outside the plug to define the thermojunction, inserting a metal end plug at the junction end, welding closed the slot and the end plug in position, and building up a V-shaped welded pad at the hot junction end.
