Title: Ultra fine metal particles
Inventor: WENTZELL JOSEPH M
IPC: B22F9/10
Filed: 1983-11-03
Abstract: A method of producing ultra fine solid metal particles comprises discharging droplets of molten metal from a rotating primary member against a secondary surface inclined to the path of the droplets whereby the droplets are atomized and pass into a cooling environment. In the embodiment illustrated in Fig. 1 molten metal droplets are discharged from a ladle or furnace 12 into a teeming ladle 14 and thence onto a rotating dish 15. The particles are forced against a secondary ring 17 provided with a sloping surface 18 facing the edge of the disk 15 at an angle inclined to a path 15a where they are atomized and pass into a cooling environment in a housing 10 having an atmosphere controlled by a unit 11. The product is collected through a valve 20 in a can 21. In a further embodiment both the primary rotating dish and the sloping surface are formed in a single unit. Thus super-alloy powders having a major portion of particles of size less than 44 microns can be produced, and these are useful in the manufacture of gas turbines. <IMAGE>

Title: Wire connectors
Inventor: HARDING JOHN PATRICK
IPC: H01R4/24
Filed: 1984-07-14
Abstract: A wire connector, particularly for use in connecting telephone wires, whether bare or insulated, which can be crimped onto the wires has an electrically insulating outer cover 2, a deformable resilient outer sleeve 4 inside the outer cover and an electrically conductive inner liner 6 inside the outer sleeve with tangs 8 for penetrating the insulation of the wire (if fitted) and establishing electrical contact with the conductor wire.

Title: Tunable viscous spring mount
Inventor: DE VRIES NEIL
IPC: F16F13/10
Filed: 1985-07-16
Abstract: A viscous spring damper particularly adapted for supporting an automobile engine is provided. The damper comprises a first fluid chamber 42 including a first wall portion defined by an elastomeric journal 28 and a second fluid chamber 44 including a second wall portion defined by an elastomeric diaphragm 50. A restrictor plate 40 is interposed between the fluid chambers and includes a main fluid port 64 and an auxiliary fluid port 66 for communicating fluid between the chambers. First and second elastomeric flaps 74, 76 are oppositely disposed about the main fluid port. The flaps are selectively tensioned and spaced from the restrictor plate to seal the main fluid port against fluid flow upon deflection of the flaps against the port in response to a preselected shock amplitude and frequency. The flaps are independently tensioned and spaced from the restrictor plate to possess the capability of having distinct natural frequencies and to seal the fluid port upon distinct amplitude deflections and frequencies during damper compression and rebound. The main fluid port is sized so that the flaps may be receptively deflected into the port upon sufficient compression of a fluid chamber to substantially limit the pressure in the chamber. <IMAGE>

Title: Tundish with gas injection tile
Inventor: PORTER WILLIAM NATHAN
IPC: B22D41/00
Filed: 1985-08-21
Abstract: A tundish used in a steel making process includes a replaceable refractory lining (16) disposed on the inner surface of the bottom and side walls of the tundish. A porous refractory tile (18) is supported upon the upper surface of the refractory lining and has a major axis extending substantially the entire width of the tundish. The tile encapsulates a conduit (22) extending parallel to the major axis. The conduit is in fluid flow communication with a source of inert gas. The conduit has a plurality of exit openings (23) for delivering inert gas into the core of the tile. The tile includes a ramp-like surface (20) for deflecting steel flowing theretowards upwardly within the tundish. The exit openings of the conduit direct the inert gas emanating therefrom upwardly through the porous tile to form a layer of inert gas across the width of the tundish, and extending above the upper surface of the tile. The tundish also includes an impact pad (30) upstream of the ramp-like surface (20). A damming effect of the tile creates a molten metal pool overlying the impact pad, and thus reduces erosion of the tundish lining. <IMAGE>

Title: Finite impulse response filters
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: H03H17/02
Filed: 1985-10-04
Abstract: A two-dimensional finite impulse response (FIR) filter comprises a demultiplexer (30) for demultiplexing an input data signal comprising adjacent digital words into p (e.g. 2) slower data signals each having a slower rate equal to 1 /p (e.g. 1 2) of the data rate of the input signal and each comprising every p<sup>th</sup> (e.g. every alternate) word of the input signal. The slower data signals are passed to p(e.g 2) filter portions (80, 82) each comprising a horizontal FIR filter (32, 34)and a vertical FIR filter (84, 86). The horizontal filters (32, 34) are each connected to receive all of the slower data signals and all of them are operative simultaneously to effect horizontal filtration by periodically processing sets of adjacent words of the input signal, the sets of adjacent words being processed at any one time by the respective horizontal filters (32, 34) being offset with respect to one another by one word. A multiplexer (36) receives output signals of the filter portions (80, 82) to form a filtered output data signal having a data rate equal to that of the input data signal.
