Patent number: 3951228Abstract: 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.Type: GrantFiled: January 6, 1975Date of Patent: April 20, 1976Assignee: Continental Can Company, Inc.Inventor: Albert C.

Patent number: 3949487Abstract: 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.Type: GrantFiled: September 5, 1973Date of Patent: April 13, 1976Assignee: Schick IncorporatedInventors: Nial C.

Patent number: 3946498Abstract: 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.Type: GrantFiled: July 31, 1974Date of Patent: March 30, 1976Assignee: Schick IncorporatedInventors: Robert S.
