Abstract: A method and apparatus for generating microbub­bles in a flowing liquid stream for use in a froth flota­tion system. The system utilizes a microbubble generator (50) having a tubular housing (53) with an inlet end (51) and an outlet end (52). Located coaxially within the housing (53) is an inner member (90) with an elongated exterior cylindrical surface. A porous tubular sleeve (80) is mounted between the housing (53)  and the inner member (90) coaxially therewith to define with the cylindrical interior surface of the housing (53) an elongated air chamber (85) of annular cross section. The porous sleeve (80) also has a cylindrical inner surface that defines with the exterior surface of the inner member (90) an elongated liquid flow chamber (99) of thin, annular cross section. An aqueous liquid is supplied to the liquid flow chamber (99) at a rela­tively high flow rate and air under pressure is supplied to the air chamber (85) so that air is forced radially inwardly through the porous sleeve (80) to be diffused in the form of microbubbles in the flowing stream.

Abstract: The two-stage reverse flame thermocombustor is consisting of four shells (1,2,3,4,) forming four chambers (A,B,C,D) of which the upper chamber (A) is acting as a storage space for fuel mixed with limestone. The second chamber (B) surrounding the first chamber, preheats the precombustion air,the flow rate of which is regulated by a fan (8). The third chamber 3, located below the first, is closed at its bottom end by a rotary disc (11) for elimination of the ashes and solid residues. The first combustion stage of the fuel and limestone takes place in this third chamber (C). The combustion gases enter the fourth chamber (D) through radial slots (13) where more air is added through a ring-­shaped bustle main (33) and nozzles (15) for final com­bustion at high temperature. Combustion gases are conveyed to the users through the duct (16).

Abstract: A thermal radiation detection apparatus has an array of pyroelectric detector devices (10) for receiving radiation from a scene whose outputs, e.g. from associated source followers (12) are supplied via a multiplexer (14) in turn to a processing circuit (20) which is responsive to each detector device signal to produce an output which substantially faithfully reproduces the received radiation signal without requiring that a chopper be used. The processing circuit operates with a correction factor to produce an output signal with first and second components proportional respectively to the device signal and its rate of change, the relative proportions of the components being in a ratio according to the device's thermal time constant. Initial device voltage level and the device's electrical time constant effects can be corrected by additional processing in the circuit (20), producing a third component of the output proportional to the integral of the device's output and in a ratio to the first component according to the electrical time constant.

Abstract: A method and apparatus is disclosed for hot-working particles of magnetically-isotropic material comprising iron, neodymium/praseodymium and boron. The method includes heating the particles (38) to a hot-working temperature; impelling the heated particles individually against co-operating working surfaces (66,68) of a hot-working device (70,72), pressing the individual particles between said working surfaces (66,68) to produce plastic flow in the particles that flattens the grains therein and thereby makes the flattened particles magnetically-­anisotropic, and removing and cooling the individual flattened particles, the flattened particles (76b) having an average grain size no greater than about 500 nm. The particles (38) are contained in a feed hopper (44) and are discharged into a spray pattern (64) of a plasma spray gun (40) by means of a pressurized gas source (48), so as to be heated to said hot-working temperature immediately prior to the heated particles reaching the working surfaces (66,68) of the hot-working device (70,72).

Abstract: A mortice latch which largely overcomes the problems of wear and breakdown in operation comprises a casing consisting of a top case (2) and a bottom case (1); a latch bolt assembly reciprocally mounted in the casing and comprising a bolt head (7), a bolt lathe (8) and a bolt end-stop (9); a latch bolt follower (23), pivotally mounted in the casing, and a return spring (33). The follower (23) has a first curved arm (25) provided at its end with an arcuate surface (26) which is engage­able with the latch bolt end-stop (9) and a second curved arm (28) which is provided with a cylindrical socket (29). A roller (31) is freely pivotally mounted in the socket (29) and the return spring (33) is mounted on a shaft (32) which extends from the roller (31). The shaft (32) extends through an aperture in a strip (17) projecting from the bottom case (1) and one end of the spring (33), which takes the form of a coil spring, bears against the strip (17) while the other end of the spring bears against a stop (34) on the shaft (32). The engagement of the roller (31) in the socket (29) of the follower provides a ball and socket type action and is such that very little wear takes place and any that does is fully compensated. The latch bolt can still be operated even in the event of failure of the return spring (33). A dead bolt assembly may also be fitted to the mortice latch if desired.

Abstract: In the method and picture signal processor for processing a first picture to be reproduced on a color picture tube , the value e ys  (12) of luminance signal for a shadow S of a second picture, which has been obtained from a preceding scanning operation (11), is subtracted (13) from the value e y  (10) of luminance signal for a desired pixel P out of video signals received, thereby determining the value e p  of a base luminance signal. Luminance signal values e s  and e h  (15) are set respectively for a shadow S and a highlight H among pixels of the first picture to be reproduced on the color picture tube (14). The value e q  (13) of a luminance signal for a pixel Q, which corresponds to the pixel P and is to be reproduced, is determined from the signal values e p , e s  and e h  in accordance with a particular correction formula. The luminance of each pixel, which is to be reproduced on the color picture tube, is adjusted (13) in accordance with the value e q  of the corresponding luminance signal thus determined.

Abstract: A thin film forming apparatus which forms a thin film over the film forming surface of a substrate (6) by spraying a mist of a source solution produced by atomization over the film forming surface of the substrates (6) heated at a given temperature. The film forming apparatrus is provided with a pair of guide members (14, 15) for supporting and guiding the substrate (6) at the opposite sides of the same. The distance between the opposite inner surfaces of the guide members (14, 15) can be changed according to the width of the substrate (6) to be supported and guided by the pair of guide members (14, 15). The distance between the respective lower portions of the opposite inner surfaces of the pair of guide members (14, 15), extending below the substrate (6) supported on the pair of guide members (14, 15) is greater than the distance between the upper portions of the opposite inner surfaces of the same, so that the distribution of the flow rate per unit flow passage area of the mist of the source solution is uniform with respect to the width of the substrate (6) and hence a thin film of a uniform thickness can be formed over the entire film forming surface of the substrate.
