Title: Improvements in the treatment of sewage and the like
IPC: C02F3/24
Filed: 1921-01-17
Abstract: 179,986. Daw, H. Jan. 17, 1921. Aerating; gravity-separation apparatus. - In aerating sewage, a portion of the liquid is rejected on its way to a sedimentation tank or other treating-means and caused to fall through the atmosphere. With the apparatus shown, sewage, lifted from a storage tank a by a chain bucket pump c driven by a turbine z, is in part delivered through a pipe d to a sedimentation tank e, while part, rejected by a valve f, falls through the down pipe of the pump below the cover b of the tank a and then through the atmosphere to the body of the liquid below. More thorough aeration of the falling sewage is attained by an air blast forced through the perforated end of a chamber g by a fan or blower h and impinging on a baffle y. Surplus air from the chamber g passes through a pipe k and is used to aerate the liquid entering the sedimentation tank e. The tank e is fitted with deflectors e<1>, e<2>, Fig. 2<a>, which divert the gases formed to the space u and thence to the atmosphere. Valves m give communication to a chamber m' in which the sludge is stored and compressed.

Filed: 1959-01-26
Abstract: 844,026. Flow meters. EKSTROM, R. A. Jan. 26, 1959, No. 2804/59. Class 69 (1). In a flow meter comprising a casing 15 forming a flat chamber having an inlet 21 and an outlet 23 at opposite sides of a vane 28 swingably mounted in the chamber, indicating means 33 being provided to show the momentary position of the vane in the chamber, the vane 28 comprises a flexible blade having a portion 30 curved through an angle in excess of 180 degrees, the end portion of the blade member to one side of the curved portion 30 being secured to the casing by means such as a bolt 29, while the other end of the blade member extends towards a wall 27 of the chamber that is curved so as to provide a gradually increasing space between the free edge of the blade member and the wall as the blade moves in the direction from the inlet 21 to the outlet 23. The curved wall 27 comprises the surface of a detachable element 25 insertable in the chamber. An armature 31 of soft iron or magnetic metal is mounted on the vane 28 or it may be integral with the vane. A pointer 33 is mounted on a pivot 34 in bearings 35 on a cover 18 (Fig. 2). A magnet 36 is attached to the pointer. A counter balance 37 is provided on the pointer. In operation, fluid entering the inlet 21 impinges in the vane 28. As the blade moves the curved portion 30 will be " wound up " so that the blade moves around movable centres x, y, z (Fig. 4). This causes the outer end of the blade to travel on a curvilinear arc which permits the calibration to be spaced almost evenly. As the vane moves the magnet 36 which is magnetically coupled to the blade 28 through the armature 31 causes the pointer 31 to move across a scale 38 on the cover. In a modification shown in Figs. 6 and 8 the vane 47 is provided with an elongated magnet 50 formed with longitudinal slots 51, 52 which are engaged by pivot points 53, 54 on the cover 53 and body 54 respectively. A pointer 55 is provided with an armature 56 to coact with the magnet 50. In a further modification shown in Fig. 10 the measuring scale 72 is calibrated directly on the upper face of the case.

Abstract: 1414107 Pet foods; artificial meat QUAKER OATS CO 21 Jan 1974 [20 Aug 1973] 02823/ 74 Heading A2B Pet food is made by admixing a proteinaceous mixture having a protein content of at least 30% with water to give a mixture containing 15 to 40% moisture, subjecting the moistened mixture to conditions of sheer elevated temperature or elevated pressure to produce a flowable substance, and extruding the flowable substance so that it does not puff and is in a translucent to glassy state. The translucent to glassy extrudate is either (a) placed in a confined space, subjected to water boiling temperature at superatmospheric pressure, puffed by releasing the pressure, mixed with a meat containing mixture so that it forms 1 to 15% of the resulting mixture, sealed in a can and retorted to sterilise it, or (b) mixed with a meat containing mixture in the unpuffed state to form 1 to 15% of the resulting mixture, sealed in a can, and retorted to sterilise and cause puffing. The protein may be soy flour, soy protein, soy protein concentrate, soy protein isolate, casein, caseinate salts, gelatin, microbiological protein, egg white, muscle protein, keratin (e.g. hoofs, hair, feathers), lactalbumen, or blood. 0.5 to 3% of oil may be included in the proteinaceous mixture e.g. soybean, wheat, corn, coconut, lard, or mineral oil or stearates or polylactic acid esters e.g. sodium stearoyl-2- lactylate. The translucent to glassy extrudate may be partially dried before puffing. The pressurisation before puffing may be for 15 to 75 seconds at 150 to 250 p.s.i. The pH of the protein may be adjusted to 4.5 to 10.5, prior to addition of water. A calcium salt e.g. dicalcium phosphate dihydrate or calcium chloride, may be included. Wheat flour, corn starch, yellow corn flour, cane sugar, dextrose, seasoning and flavouring may also be added. The meat mixture may contain cereal e.g. oats, barley, silo.

Abstract: 1,248,796. Mass spectrometry. SABA SCHWARZWALDER APPARATE-BAU-ANSTALT AUGUST SCHWER SOHNE G.m.b.H. 17 Jan., 1969 [20 Jan., 1968], No. 2922/69. Heading G4H. [Also in Division H3] The distribution of mass density signals when a mass spectrometer is swept by the output of an ion acceleration potential generator is synchronized with switching pulses from a generator so that each mass density signal is distributed on to a line according to its mass number and consequently, by examining particular lines, a warning signal may be given if coincidence of particular mass density signals is established. Rectangular pulses from a Schmitt trigger (16, Fig. 4, not shown) connected to an oscillator (15) are fed via a bi-stable (17) to an eight-stage binary counter (18a-18d, 19a-19d) the lower four stages controlling a first diode matrix (20) and the higher four stages a second diode matrix (21). Selected ones of the matrix output control the ion acceleration potential generator (Fig. 2, not shown) the remaining outputs being fed to a further matrix (Fig. 5, not shown) to sequentially prime each of its output leads (J 1 . . . J 224 ), the mass density signals (on input 24) resulting in a pulse on the associated output line. Selective output leads are connected as an AND gate (Fig. 6) so that if a pulse occurs on all inputs 25-27 to the gate the positive signal of the common point of diodes 34-36 enables D.C. amplifier 37a-37c so that a positive warning signal on output 39 is given and a selected mass density signal e.g. 27 is fed via output terminal 39a for quantitative evaluation. A particular range of signals may be examined in the circuitry of Fig. 7 by feeding selective outputs from the matrices of Fig. 4 to set a bi-stable 42 for the scanning period corresponding to the range to be examined. The switching pulses corresponding to harmless mass numbers expected during this period are connected to gates 46, 47, 48 to short circuit the bi-stable 42 during their occurrence but the signals from dangerous gases in this range are fed from input 44 via amplifier 52a-52c to trigger a warning signal.

[Class 38(iii)] A, control system for two separate motors connected in parallel to a current supply source and normally sharing a load, for example one or more fans, incorporates means operating automatically upon failure and cutting out of circuit of either motor to reduce the flow of current through the other motor which still continues to operate. Normally motors A and B are connected in parallel by closure of switches 5 and 6, resistors 3 and 8 being short-circuited by relays 4 and 7 respectively. When the motor A fails, for example, the switch 5 opens to isolate that motor, and the solenoid 13, which is connected across the armature 2, is de-energized to introduce resistor 8 in series with armature 9 so limiting the current therethrough. Similar operation occurs when the other motor fails. In an alternative arrangement, resistors included in the field circuit of each motor are short-circuited to provide increased field strength of one motor upon failure of the other. The short-circuiting devices may be centrifugally operated. Inductances may replace the protective resistors.
