Abstract: Portable fire drill training apparatuses which mimic an actual building install of a fire alarm system for training in localized areas are disclosed. In one example approach, a portable fire drill training apparatus is described which lacks any heat, smoke, or fire detectors and comprises an enclosure, a fire alarm notification appliance mounted on the enclosure, and a manual fire alarm activation device with an actuation element, where the manual fire alarm activation device is mounted on the enclosure and is configured to activate the fire alarm notification appliance in response to a user engaging the actuation element.

Abstract: A method and apparatus for the production of a deposit such as a bar (1) is provided. The deposit has a longitudinal outer surface (2) and a front face deposition surface (3). The spray deposition comprises atomized droplets produced by outer and inner sprays (4 and 5). The outer and inner sprays (4 and 5) are both directed such that, during deposition, a substantial proportion of droplets from both sprays are deposited on the front face (3) of the forming deposit. The inner spray (5) has a higher gas to metal ratio than the outer spray allowing an increase of both deposition and final product yield.

Abstract: Multi-chip module (MCM) (10) includes package body (12) having cavity (20) for accepting a plurality of devices and substrates and seal ring (26) to ensure the integrity of the package. Lead frame (18) having a plurality of individual leads (28) is coupled to the package body (12). Plurality of test points (38) or test pins (30) are located on the external surface of package body (12). A plurality of bond pads are located in cavity (20), including a first set or tier and a second set or tier of bond pads for electrically coupling the devices and substrates in the cavity (20) external to package body (12). The first set or tier of bond pads provides electrical connection between the individual devices in MCM (10) to plurality of test points (38) or test pins (30), and the second set or tier of bond pads provides electrical connection between the individual devices in MCM (10) and plurality of individual leads (28).

Abstract: A molten metal gas-atomizing spray-depositing apparatus has an atomizer which employs a pressurized gas flow for atomizing a stream of molten metal into a spray pattern of metal particles being initially hotter than the solidus temperature of the metal. The apparatus also has a substrate system which includes an outer substrate of metallic foil and an inner substrate for supporting the outer substrate. The outer foil substrate is movable relative to the metal particles in the spray pattern thereof and disposed below the atomizer for receiving on a surface of the foil a deposit of the particles in the spray pattern to form a product on the outer foil substrate. The outer foil substrate is of a thickness which is less than a predefined maximum thickness at which the capacity of the foil to absorb heat from the deposit is equal to the latent heat and super heat, if present, of the deposit.

Abstract: There is provided a method of spray deposition in which a stream of liquid metal or metal alloy is atomized inside a spray chamber into a spray of atomized droplets. A metal or metal alloy collector is rotated about an axis transverse to the mean axis of the spray and in the path of the spray so that a deposit is formed about the collector with a bond between the deposit and the collector sufficient to isolate the interface from oxygen penetration. The collector is then retained as an integral part of the final product and further processed to substantially eliminate porosity in the region of the bonded interface. The collector and the deposit may be the same or different materials, and the bond between the deposit and the collector is preferably enhanced by plasma heating in the region disposition. The invention also provides a plant for carrying out the preferred method arc plasma heating.

Abstract: A rapid solidifcation rate (RSR) route aluminum alloy contains lithium and a dispersoid forming ingredient selected from niobium, molybdenum, hafnium, tantalum, and tungsten. These dispersoid forming ingredients resist coarsening in the matrix at solution treatment and ageing temperatures. The dispersoid forming ingredient is preferably present in 0.2 to 5.0 percent by weight.

Abstract: An alloy formed by rapid solidification comprising Al, 1 to 7 wt % Cr and up to 6 wt % X where X is selected from refractory metals Nb, Mo, Hf, Ta, and W, has improved thermal stability.
