Abstract: There is disclosed a protective device having a conventional hard hat and a pair of ear warmer pads. The pads are connected together above the top of the head of a wearer of the hard hat by a strap and are detachably attached together below the chin of the wearer. The hard hat comprises an outer protective shell, a support webbing and a support band. The webbing supports the shell on the head of the wearer to define a space between the shell and the head. By passing the strap through the space, and attaching the pads together beneath the chin, the pads are held against the ears and the hard hat is held on the head of the wearer. The pads are of a thickness such that they can be stored in the space between the shell and the head of the wearer, thus eliminating the necessity of having to remove the pads from the hard hat when the pads are not in use.

Abstract: A mounting system for mounting a face guard on a football helmet, wherein the face guard is able to pivot about a horizontal axis about the top portion of the helmet.

Abstract: A method and apparatus for staking a formable projection, for example, a tab or boss, to retain plural articles in a unitary assembly. A projection on a first article is brought into registering position with an aperture in a second article to form the assembly. The assembly is clamped by a spring-loaded clamp pad which bears against the second article and surrounds the projection. The projection is then staked by action of a tool which travels reciprocally within the clamp pad and has a tip which cooperates with the clamp pad to form a cavity of desired shape. The forming stroke of the tool is against the resistive force of the spring, which increases the clamping force of the clamp pad. The formed projection is therefore contained within the inner boundary of the clamp pad and tool tip to thereby promote uniform head formation.

Abstract: A new technique for forming CMOS custom logic circuits is disclosed wherein standard cells (10,12,14) are used and the prior art technique of field oxide isolation (16) is replaced with transistor isolation (68-71). That is, the boundaries (18,20,22,24) between the cells are formed by transistors that are permanently "off", i.e., tied to the positive or negative voltage supply, depending on whether the transistors are p-channel or n-channel devices, respectively. Therefore, instead of having to deposit separate p+ and n+ source/drain diffusions for each cell, as in the prior art, a single p+ diffusion strip (60) and a single n+ diffusion strip (62) are utilized, where the polysilicon mask of both the logic and isolation transistors defines the cell sizes. Thus, the p+ and n+ diffusions become generic steps which do not vary from circuit to circuit, decreasing the turnaround time associated with custom logic circuit layout and design.
