Abstract: A continuous autogenous multi-stage process for converting non-ferrous metal sulfides, in an oscillating, elongated, gently sloped, sealed, tiltable, rounded cross-section furnace, discharging crude metal or low-iron matte at one end, and silicate slag and sulfur dioxide-rich gas at the other end. The concentrates, fluxes, commercial oxygen, sulfur dioxide, a carbonaceous reducing agent and optionally other materials are introduced into the furnace in stages to provide a molten bath of slag and matte flowing countercurrently. Slag scavenging is accomplished by deconverting to produce low grade, cleansing matte in situ in the slag layer, followed by settling. At least a substantial proportion of the commercial oxygen is continuously blown in through injectors extending through the refractory lining of the vessel and communicating with its interior below the bath surface, where necessary with a protective fluid, desirably surrounding the oxygen. Oscillation of the converter causes the injected gases to sweep back and forth through the bath, and distributes the solids over its surface to provide bath turbulence and interphase contact. Off-gases are desirably recycled. Flexible control means and special apparatus are disclosed.

Abstract: In a telephone switching facility, line circuits are arranged in groups, each including a local ringing battery bus, and a universal high level signal generator (UHLSG) for providing ringing and other high level signals to the line circuits via the local ringing bus. Each generator is responsive to address signals from a controller in the switching facility to generate selected high level signals. The UHLSG includes a switching bridge driven by a width modulated signal stream of periodically occurring pulses having assertion times suitable for developing a high level signal across a network at the output of the switching bridge. The width modulated pulses are generated from period and time signals. The period signal occurs once with each sequence in repetitively generated data byte sequences. The time signal occurs with correspondence between a selected stored data byte and an instant one of the data bytes of the sequence. A plurality of the stored data bytes are arranged in ranges in a storage circuit. One bit in the last data byte in each range causes the storage circuit's next readout to be from the beginning of a range as directed by the controller in the switching facility.

Abstract: An internal combustion engine (10) comprising an engine frame (12) having a drive shaft (20) rotatably mounted therein and extending outwardly therefrom. A pair of cylinder sleeves (40, 40') are mounted on the engine frame (12) and have their inner ends positioned within the interior of the frame and their outer ends positioned outwardly thereof. A cylinder head (60, 60') is secured to the outer end of each of the sleeves and is separated thereby by means of a heat insulative gasket (70). Each of the cylinder heads (60, 60') has a dome-shaped chamber (62, 62') formed therein which is in communication with a source of combustible fuel. An air inlet conduit (94) is mounted on one end of the engine frame and is in communication with a source of air under pressure such as a blower, super-charger or the like. The air inlet conduit is in communication with an air passageway (100) formed in the engine frame (16) which is in communication with air inlet openings (52, 52') formed in the cylinder sleeves (40, 40'). The cylinder sleeves (40, 40') are provided with exhaust openings (54, 54') formed therein which communicate with an air exhaust passageway (102) formed in the engine frame (16). The exhaust passageway (102) is connected to exhaust conduit (106) or pipe extending from the engine frame (16). A piston (72, 72') is slidably mounted in each of the sleeves (40, 40') and has a dome-shaped head portion (76, 76') which is adapted to be received by the dome-shaped chamber (62, 62') in the cylinder head (60, 60') when the piston is in its top position. In the top position, the small "air space" (118) is present between the walls or sides (78, 78') of the piston head (76, 76') and the walls or sides of the sleeves (64, 64'). The "air space" (118) serves as a means for retarding the absorption of heat into the sides of the piston head (76, 76') and the sides of the cylinder sleeve (40, 40'). In the down position, the "air space" (118) also serves to spread the cooling air into a thin, wide sheet for more efficient cooling of the cylinder head (60, 60') and sleeves (40, 40'). Optional air deflecting fins (84, 86, 84', 86') may be employed on the piston head (76, 76'). The rings (82, 82') of the piston (72, 72') are conventionally lubricated and slide upon the interior wall (52, 52') of the cylinder sleeve (40, 40'). Each of the pistons (72, 72') has a roller (88, 88') mounted on the skin portion (74, 74') thereof which rolls upon a cam (32) mounted on a rotor plate (30) which is secured to the drive shaft (20) for rotation therewith. A return roller (92, 92') is also operatively mounted on the skin portion (74, 74') of the piston (72, 72') for engagement with a return cam (36) which is mounted on the drive shaft (30) for rotation therewith.
