Abstract: 1,235,948. Sewage treatment. ECODYNE CORP. 27 March, 1969 [29 March, 1968], No. 16099/69. Heading C1C. A sewage treatment plant comprises a tank 10 which includes a clarifier section 47 and an aeration section 30 in which an aerator 50 causes solid-bearing liquid sewage to follow a rotational flow path, inlet ports 55 in a partition 31 through which a portion of the rotating sewage flows into the clarifier section, means (e.g. a channel 65 formed by the partition and a secondary baffle 60) to direct the flow of the portion of rotating sewage downwardly in the clarifier section, and an outlet 46 through which solids descending in the clarifier section flow back into the aeration section. The tank 10 may be of sheet steel and receive the sewage through a pipe 23. The sewage passing into the clarifier section 47 is throttled by the inlet ports 55 and the secondary baffle 60 so that it flows from the channel 65 and down the partition 31 in laminar fashion. Floatable solids which rise to the surface in the clarifier section 47 and an inlet chamber 68 of the clarifier section are returned by the rotational flow of the sewage to the aeration section 30 through an assembly 80 which comprises a trough (81), Fig. 2 (not shown), which extends from the clarifier section to the aeration section. The trough (81) has an inlet (83) in the clarifier section 47, lateral inlets (85) in the inlet chamber 68, convergent inner side walls (86), and a wedgeshaped plate (90) adjacent an outlet (82) in the aeration section 30. Clarified effluent leaves the tank 10 via a weir 75. In a modification, Fig. 3 (not shown), the tank may have two aeration sections (130), (130a), each separated from a central clarifier section (147) by partitions (131), (131a).

Title: Improvements in and relating to the treatment of ores and the like containing manganese
IPC: C22B47/00
Filed: 1928-06-19
Abstract: 319,605. Dicker, S. G. S., (Bradley- Fitch. Co.). June 19, 1928. Drawings to Specification. Divided on 319,392. Manganese sulphate and salts thereof in general. - The leaching of materials containing manganese as manganous oxide with a solution of an ammonium. salt such as the sulphate is carried out by using considerable excess of the leaching reagent, for instance with more than two molecular equivalents of the ammonium salt to each molecular equivalent of manganese in the material treated. Leaching may be effected in two stages, partly exhausted leach liquor being used to treat unleached material with simultaneous grinding of the larger particles of ore, and fresh solution to extract the partly leached material. Ammonia produced during leaching is removed, as by using elevated temperatures, say 200‹ F. with or without reduced pressure, and a shallow depth of liquor, for instance 18 ins. at normal pressure; or ammonia may be removed by blowing, boiling, or neutralization. The material may be pretreated as described in Specification 321,943, and manganese be recovered from the solutions obtained as described in Specification 319,392. A flow sheet for the process is included in the Specification. Specification 284,098 also is referred to.

Patent GB-163794-A (GB)
Abstract: 163,794. Lucas, H., and Ireland, H. W. F. Feb. 24, 1920. Magnetos, driving. - In a magneto trip mechanism in which parts on the driving and armature shafts are spring-connected and in which a pivoted lever on the armature part engages a fixed abutment until released by a cam on the other part, the cam serves the double function of moving the lever to the release position and locking it in an inoperative position and transmitting the drive through it. The lever c, is pivoted on the disc a on the magneto shaft b through the slotted flange of which its end d projects at e at slow speeds in order to engage a fixed abutment on the magneto frame. A disc i on the driving-shaft h is connected to the disc a by a spring j and has a cam k which, after a predetermined rotation, releases the lever from the abutment by pressing on it at l to give the spark. At high speeds, the part l flies out centrifugally drawing the projecting part d within the flange and causing a hook m on the lever c to engage a corresponding hooked part on the cam and carry the drive directly.

Title: Production of glide and portamento in an electronic musical instrument
IPC: G10H7/10
Filed: 1975-04-21
Abstract: 1500585 Electrophonic musical instrument NIPPON GAKKI SEIZO KK 21 April 1975 [29 April 1974] 16392/75 Heading G5J Apparatus for producing glide or portamento in an electronic musical instrument comprises means for establishing a time varying fractional frequency number S, and means for modifying the frequency number R<SP>1</SP>, currently being sounded, in increments of S until the glide or portamento ceases when R<SP>1</SP> tends to R, the preselected frequency number. A simple glide effect is produced (Fig. 2, not shown) by entering R into the m=4 position of a shift register so that S = R/2<SP>m</SP> = R/16, then adding R to S to give R<SP>1</SP>. (S may be made negative by a complementing circuit). Clock pulses increment m by 1 until m = 16 when the glide ceases and the preselected note is sounded. A slalom glide effect, where the sounded note is at first a predetermined interval flat then sharp and finally tends to the preselected note, is achieved by the circuitry of Fig. 3. S is produced in shift register 56 (and made negative in complementing circuit 27<SP>1</SP> if flip-flop 58 is set to 1) and added to R in adder 28<SP>1</SP>, from where it is relayed to the sound-producing circuit (not shown). Shift register 56 moves its contents one place to the right (divides by 2) at each pulse from clock 13, which pulse is also registered on counter 63. When m increases to 16 line 68, via gate 69, goes high, making flip-flop 58 go low and disabling complementing circuit 27<SP>1</SP> so that S is positive and R<SP>1</SP> is greater than R, and at the same time register 56 is reversed so that it shifts to the left and counter 63 counts down. When m=4 (a difference of about a semitone from the pre-selected note) the counter and register are again reversed, by line 64 going high, until R<SP>1</SP> tends to R when m= 16 again and flip-flop 74 is high so that clock 13 is blocked at gate 78, at which point the glide is terminated and the preselected frequency is sounded. Two circuits are described for producing portamento. In the embodiment of Fig. 4 (not shown) the current frequency number R<SP>1</SP> is divided by k (a constant) and added to or subtracted from R<SP>1</SP> depending on whether the second played note is higher or lower than the first. In this way a first note slides all the way to a second note. In the embodiment of Fig. 5 (not shown) the difference between the first and second played frequency numbers is divided by constant k in divider (101) so that a constant increment DR<SP>1</SP> is added to the previous increments in accumulator (103) at each pulse from clock (107). The sum of the increments are added to the first note frequency number in adder (111) to give the current frequency number to be relayed via line (14) to the sound-producing circuit. A comparator (123) detects when the current frequency number passes the preselected frequency number and resets flip-flop (117), terminating the portamento.
