20100024822 | REDUCED PROFILE MULTIPLE GAS CYLINDER ALTERNATIVE - An improved self contained breathing apparatus (SCBA) includes a large cylindrical tank of a first diameter having a first weight when holding a first quantity of a breathable gas under a first pressure, an on/off valve, a pressure regulator and a gas distribution device. The improvement comprises replacing the large tank with at least two smaller cylindrical tanks, each of a second diameter which is substantially smaller than the first diameter and a pressure header in fluid communication with each smaller tank and the on/off valve. The smaller tanks and the pressure header have a second combined weight when holding a second quantity of the breathable gas under a second pressure. The second combined weight is substantially the same as or less than the first weight when the first and second pressures are substantially the same and the first and second quantities of the breathable gas are substantially the same. | 02-04-2010 |
20100207410 | Opposed Spring-Loaded Anchor Hook Supporting Device - An anchor hook supporting device is for use with an anchor hook having a hook end for engaging a first surface of a support member and a shank end which includes an eyelet opening for receiving a rope or cable. The supporting device includes an attachment assembly for being secured to the shank end of the anchor hook and an engagement assembly for engaging one of a second surface of the support member and another surface which is fixed with respect to the support member. A biasing member having a first end secured to the attachment assembly and a second end secured to the engagement assembly biases the engagement assembly toward the attachment assembly to bias the shank end of the anchor hook and the engagement assembly toward each other for holding the hook end of the anchor hook on the first surface of the support member and the engagement assembly on the second surface of the support member or the other surface. | 08-19-2010 |
20120297526 | Helmet System - A protective helmet includes a head cap, which surrounds and moves with a wearer's head, and an outer shell which surrounds the head cap. The outer shell is movable both radially and circumferentially relative to the head cap. An energy absorbing flexible liner is located between the head cap and the outer shell. The liner is attached to the outer shell and the head cap so that neither the head cap nor the head of the wearer is otherwise attached to the outer shell. The liner establishes a preset initial relative position and spacing between the head cap and the outer shell and compliantly absorbs energy imparted to the outer shell during a helmet impact to enable the outer shell to move relative to the head cap during the helmet impact and to be returned to the initial relative position with the head cap following the impact. | 11-29-2012 |
20130232667 | Helmet System - A protective helmet includes a head cap, which surrounds and moves with a wearer's head, and an outer shell which surrounds the head cap.

20150216249 | HELMET SYSTEM - A protective helmet for successive impacts includes a head cap adapted to surround and move with a wearer's head and an outer shell which surrounds the head cap. An energy absorbing flexible liner predominantly comprised of radially oriented foam columns is attached to both the head cap and outer shell. The liner establishes a preset initial relative position and spacing between the head cap and the outer shell and compliantly absorbs energy imparted to the outer shell during a helmet impact to enable the outer shell to move linearly and angularly relative to the head cap during the helmet impact and to be returned to the initial relative position with the head cap following the impact. | 08-06-2015 |
