Abstract: A hermetically sealed disc drive comprising at least one aluminum alloy housing component manufactured with a thermally directed die casting press subassembly is disclosed. In one embodiment, the thermally directed die casting press subassembly comprises a thermally directed funnel gate that is skewed to sample molten material from an off-center portion of the shot sleeve. Disc drive housing components can be manufactured by injecting an aluminum alloy slurry from the shot sleeve through the thermally directed funnel gate and the injection nozzle into the die cavity. The aluminum alloy slurry may be a thixotropic slurry comprising a uniform primary aluminum particle size in the range of approximately 50 to 80 microns. The primary aluminum particles of cast products produced according to the methodology of the present disclosure, with the aforementioned particle size distribution, are free of encapsulated eutectic at the micron scale.

Abstract: A casting component comprising essentially no macro porosity by having the casting material fill the mold cavity with a laminar flow is disclosed. In one embodiment, the gas within the mold cavity will not be entrained when the flow is laminar. Control of this flow behavior is directly related to the microstructure and thixotropy of the alloy. The SLC slurry have a thixotropic nature and a non-turbulent way of flowing into a casting die, allowing the process to be capable of producing cast parts having thin sections, geometric complexity and close dimensional tolerances without entrapped gas porosity. The thixotropic aluminum slurry may be characterized by a uniform primary aluminum particle size in the range of 50 to 80 microns. A uniform distribution of this microstructure throughout the injected aluminum volume encourages laminar flow of the aluminum into the die cavity.

Abstract: Universal L shaped brackets, supports, apparatus, systems and methods for mounting surveillance cameras that form enclosure systems, mounting systems, and pedestal system for the cameras to be mounted on structures, such as but not limited to under a ceiling, a shelf, a wall, inside a pedestal and the like. Another embodiment covers brackets, supports, apparatus, systems and methods for mounting surveillance cameras with a universal mount for inside of vehicles, such as automobiles, and the like. The mounts can include mounting cameras on the backs of seats or door edges. The mounts can mount the cameras inside of pedestals.
