Title: Improvements in centrifugal apparatus for separating and collecting dust or other solid particles from air and gases
IPC: B04C5/00
Filed: 1928-12-05
Abstract: 327,703. Cheltnam, C. H. W. Dec. 5, 1928. Density separators.-Centrifugal apparatus for separating and collecting dust from gases consists of a primary separator superposed upon a secondary separator, the clean gas outlet rising from the primary separator and containing a liner so that an annular diffuse is formed. In the form shown in Fig. 1, the primary separator consists of a cylindrical head A and an inverted frustum B, the material entering the head tangentially at C. The secondary separator consists of the frusta L, M with the dust outlet D. A plate N is supported in the position shown by lugs O. The gas outlet E has an increasing diameter in the outward direction and may be attached to a pipe. A core F is fixed in the outlet E to leave a discharge passage of increasing cross-sectional area in the direction of flow. The vanes J which support the conical end H of the core have curved lower portions which meet the outgoing gas without shock. The first separation occurs in the upper vessel and dust-laden gas passes downwards through the annular space between the plate N and the walls of the chamber. The dust enters the outlet D and the clean gasrises through the hole in the plate N to the outlet E. In the modification shown in Fig. II the plate N is omitted and the core F is extended to enter the secondary separator. The gas outlet discharges direct to the atmosphere and is covered by a weather hood P. The clean gas may be discharged through a chamber of scroll formation, the axis of the outlet from the scroll being at right angles to the axis of the outlet E.

Filed: 1975-09-01
Abstract: 1495463 Measuring material levels HYER INDUSTRIES Inc 1 Sept 1975 [30 Sept 1974] 35932/75 Heading G1H Apparatus for indicating the level of fluent material in a container comprises a member, such as a chain formed of elements capable of limited axial rotation relative to each other, with its ends secured above and below the material, the elements being such that those beneath the material are inhibited from rotation by it and means to rotate the upper end only until the limited movement between all the elements above the material has been taken up, the total of this movement providing a measure of the material level. In one arrangement, a chain 6 composed of flat plate links 12 is anchored adjacent the bottom of a hopper 1. Its upper end is connected to a transmission cup 23 of a fluid coupling containing a viscous fluid 25 in which stirrers 45 are rotated by a motor 31. The cup drives a magnetic switch 51, 53 through a belt 36, the switch operating a counter (not shown). The motor is programmed to rotate in opposite directions for timed periods causing corresponding twisting of the chain until resistance of the material following take-up of the free movement causes the fluid coupling to slip. The rotations counted are converted to a digital display of material depth. In another form a cable 99 having links 97, 98 is used.

Title: Signal line monitoring circuit arrangements
IPC: G08C19/02
Filed: 1973-08-01
Abstract: 1417292 Measuring signal current in a two-wire telemetry system C I L ELECTRONICS Ltd  1 Aug 1973 36581/73 Heading G1U In a two-wire telemetry system of the type in which the two wires carry a direct current equal to the sum of a datum current (4mA) and a signal current (0 to 16mA) a circuit 1, Fig. 2 is provided, which when inserted in series in the two wires, provides both a stabilized output voltage which may be utilized by any device such as a load 24, and a signal voltage proportional to the signal current. As described the circuit provides three parallel paths through which the line current may flow: a first including a resistor 11 and a zerer diode 14 which provides the stabilized output voltage; a second including resistors 12, 16, 17; and a third including a pair of transistors 21, 22, acting as a controlled impedance, and a fixed resistor 23 across which the output signal voltage is developed. The circuit is initially adjusted so that when the signal current is zero and only the datum current is flowing, an amplifier 10 receives equal inputs and cause the transistor pair to assume a high impedance condition. When a signal current also flows, the upper input to the amplifier tends to rise but because of the high gain of the amplifier and the effective feedback around it from the transistor pair 21, 22 the rise is very small and just sufficient to cause substantially all the signal current to pass through the transistor pair and the resistor 23. In other words the circuit is such that a constant current (equal to the datum current) always flows through the first two paths, and any excess current (equal to the signal current) flows through the third path.
