Title: Apparatus for separating grease, oils and fats from waste water
IPC: C11B13/00
Filed: 1947-08-21
Abstract: 633,905. Gravity-separation apparatus. NEWMAN, R. H., and HIRSHSTEIN, M. P. Aug. 21, 1947, No. 23202. Convention date, Oct. 4, 1938. [Class 46] A grease, oil and fat retrieving device comprising a continuous flow receptacle 10, Fig. 1, having a waste water inlet 14 at one end and a waste water outlet branch 15 at the other end disposed to determine the normal water level within the receptacle is provided with a water baffling system including a partition wall 40 dividing the water chamber into a turbulence zone T and a relatively quiescent grease collecting zone Q and a series of baffles 43, 44, 45, 47 and 50 adjacent the inlet 16 which divide the inflowing waste waters into two auxiliary streams and a main stream, one of the auxiliary streams being directed toward the outlet 30 at the bottom of the outlet riser 27 and the other auxiliary stream being directed upwardly and then horizontally against the separated grease, &c., and the main stream being directed into the turbulent zone T to facilitate the separation of the grease, &c., from the inflowing waste water. The partition wall 40, spaced closer to the outlet than to the inlet end, has its lower end slightly above the upper edge of the outlet 30 and extends upwardly substantially above the centre line of the inlet 14 and outlet 15 and is provided with a plurality of slots 41 enabling the separated grease, &c., to flow from above the zone T to above the zone Q. The incoming waste water is deflected downwardly by the main baffle 43, which extends vertically above and below the entire area of the inlet opening, and one auxiliary stream is separated from the main stream by the baffle 44, extending downwardly a substantial distance below the lower edge of the baffle 43 but not as far as the bottom of the receptacle 10, the main stream then impinging against the next baffle 47 whose bottom edge is just clear of the bottom 10, and is directed upwardly into the turbulent zone T. The second auxiliary stream flows under baffle 47 and under another baffle 50 in the form of a broad shallow stream towards the outlet 30 and together with a centrally located channel 34, Fig. 3, assists in the shifting of solids towards the outlet. Baffle 50 also defects a portion of the main stream upwardly to create an upwards pressure in the turbulent zone T. The first auxiliary stream rising between baffles 43 and 44 is directed into the grease collecting region of the turbulent zone T by another baffle 45, provided with slots 46, thus causing the accumulated fats to be driven into the quiescent zone . Q. A draw-off opening 52 is provided in this zone at a sufficient elevation to permit the upper part of the built-up column of grease to escape into the grease receptacle 11. The elevation of the opening 52 may be adjusted by the eccentric rings 52a and 52b. The outlet branch 15 is formed on a riser 27 extending from the receptacle outlet 30 and an air release passageway 55 is provided from above the grease collecting zone to a point located adjacent to and beneath the outlet.

Abstract: 1435733 Automatic control of pressure TOYO SODA Mfg CO Ltd 16 May 1973 [17 May 1972] 23367/73 Heading G3R The pressure of a fluid delivered by a reciprocating pump is automatically regulated, the control being modified by a signal dependent upon the speed of the pump drive. In the embodiment, a piston-cylinder pump 1, 2 supplies liquid under pressure to a separation column in liquid chromatography apparatus. A signal dependent upon the pressure in the cylinder, as measured by a strain gauge 23 on a deformable diaphragm 5 of the cylinder, is amplified at 26 and compared in differential amplifier 24 with a desired value 29. Any difference is used to vary the speed of D.C., synchronous or pulse motor 11 that drives the reciprocating piston. The difference signal is modified in amplifier 31 by a rate feedback i.e. by the speed of motor 11, as sensed by tachometer 24, to damp pressure oscillations. Two such pumps applying suction or pressure may be used alternately.

A D.C. leg signalling system, in which a line leg is connected to earth at a substation 100 by either, neither, or both of two oppositely poled rectifiers 103, 104, the leg being tested from the exchange by potential of one polarity followed by potential of the other polarity, has a receiver to detect the connection or disconnection of each substation rectifier; each receiver, such as that for diode 103, comprising a resistor 120 the potential drop across which charges a capacitor 122 over diode 123 if the diode 103 is keyed to the leg, the capacitor discharging over diodes 126, 129 to set a bi-stable 116 when the test potential + U is disconnected. The diodes in the receiver for diode 104 are reversely poled. Disconnection of the test potentials is delayed so that line capacitance is charged fully to ensure that, when the leg is not connected to earth with respect to the test polarity, no charge exists on the test capacitor when the test potential is lifted.

Title: Improvements in or relating to implements for working crop lying on the ground
IPC: A01C3/08
Filed: 1965-06-01
Abstract: In a haymaking machine of the type having driven rotary rake-heads 4-7 rotatable about axes extending downwardly and rearwardly from a frame 1, rearwardly-extending rods 31 are mounted above the rake-heads to reduce the scatter of crop discharged by the heads. The heads are mounted in pairs on beams 2, 3 each pivoted to the main frame-beam 1 about an axis concentric with the head and also about the axis of pivot-pins 12, the latter pivoting allowing floating of the heads to accommodate ground-irregularities.  The beams 2, 3 can be swung about the outer pivotal axis to extend perpendicular to the beam 1, for transport.  Brackets 26 at the ends of the beam 1 carry a beam 27 which is adjustable about its longitudinal axis and lockable in various positions.  Rods 31, downwardly bent at their rear ends, are equally spaced along the beam 27 at distances approximately equal to 1/3 of a rake-wheel diameter.  The device is mounted on wheels 10 at the centre of each rake-head, the heads being driven from the power take-off of the towing tractor through a jointed shaft 24 and transmission housed in the hollow beams 1, 2, 3.  An adjustable drawbar 19 is attached to one of the beams so that the device may be drawn offset; it may be towed endways, for transport.
