Abstract: 188,958. Activated Sludge, Ltd., and Coombs, J. A. Nov. 22, 1921. Plant; aerating; bacteriological processes; manures. -Apparatus for the activated-sludge or similar process comprises in addition to the ordinary treating and settling- tanks, a plurality of connecting chambers by means of which any of the treating-tanks may be byepassed. The activated sludge or the sewage itself may be inoculated with nitro-fixing organisms or with anaerobic organisms according as sludge is or is not required for use as fertilizer. Fig. 1 shows an arrangement of treating-tanks 1, connecting-tanks 10 and settling-tanks 50. Each tank 1 has two parallel compartments separated by a partition wall 2. They are connected with one another and with the tanks 10 by passages 24, 12, 14. The first of the treating tanks 1<x> may be used for the aeration of the sludge which is normally added to the liquid, brought to the apparatus by a channel 5, in the first tank 10. From the latter the mixed sludge and liquid is passed successively through such of the tanks 1, 10 as are in connection and thence directly from the last tank 1 or through a draw-off pipe 37 to a sump 39 and a pipe 44 leading to the settling-tanks 50. The supply to the settling-tanks may be controlled by air-locked siphons as described in Specification 170,032. Sludge settling in the tanks 50 is raised by air lifts 51 to a. channel 21 and passed through air lifts 20, chambers 19 and a pipe 18 either to the tank 1<x> or to a pipe 6 which is in connection with the channel 5 and has outlets to each of the tanks 10. If it is desired to cut any one of the tanks 1 out of series, purified effluent from the settling- tanks is brought back by a pipe 32, air-lift 31, and pipe 30, to fill the tank and drive out the sludge therefrom to the sump 39. The danger of sludge left in a tank, which is out of use, becoming septic is thus obviated and strain on the walls of an empty tank prevented. Modified plant is described in which tanks 10 are placed at both ends of the tanks 1. Specifications 11368/01 and 636/03 also are referred to.

Title: A Method of Adjusting the Position of Mechanical Control Elements by Electric Servo Motor Means and an Arrangement for Performing the same
IPC: G05B19/414
Filed: 1967-07-07
Abstract: 1,183,993. Control of stepping motors. BADISCHE ANILIN- & SODA-FABRIK A.G. 7 July, 1967 [8 July, 1966], No. 31435/67. Heading H2J. [Also in Division G3] In an arrangement for regulating stepping motors 11 driving valves 5, a digital computer 1 stores reference signals supplied through switch la and is connected cyclically to several control systems by switch 2a associated with scanner 2. Each control system 4, which is monitored during each period of scan, supplies signals representing the value to be controlled back to the computer 1 through an analoguedigital converter 3. The computer supplies an error signal through scanner switch 2b to memory device 16 which retains it in digital form, the device comprising units each associated with a control system 4. A pulse generator 6 converts the digital error signal into pulse trains which are applied, according to direction of correcting motion, through a phase control circuit 7 or 8 responsive to a force-measuring or position-detecting unit 9, and through a power gate 10 to the motor 11. In another arrangement, for obtaining maximum speed of actuation, the output of the unit 9 is returned to the computer, the unit 9 being digital in character such as a photo-electric or inductive detector responsive to the angular rotation of the disc armature of the servo motor. This enables complete pulses to be fed to the power gate except the last of a train which is interrupted when the desired position has been reached whereupon a controlled rectifier, forming part of the power gate, is quenched. In another embodiment, only one power gate 10 is required for all the actuators in the plant served by the computer 1, this power gate being supplemented by a stand-by unit. The signals supplied to the power gate may be restricted to prevent damage to the valve.

Title: Improvements in control mechanism for winding engines and the like
IPC: B66B1/12
Filed: 1926-12-13
Abstract: 287,212. General Electric Co., Ltd., and Woollatt, G. S. Dec. 13, 1926. Regulating and control-transmitting gear for winding and paying-out apparatus; brakes. - In controlling-mechanism for winding-engines an auxiliary brake engine and at least one other auxiliary controlling-engine adapted to perform a different function are controlled by the same lever and an emergency brake lever also is provided which actuates all the brake engines of the winding-gear simultaneously. Fig. 1 illustrates a brake engine 1 and clutch-engine 2 controlled from the lever 3. The action in this case is governed by the lost motions provided by the slotted links 6, 7. Thus, starting with the lever 3 in its right hand position in which the link 9 has been depressed to declutch and the link 8 raised to the braking position, the, movement of the lever back to mid-position is an idle movement, both links 6, 7 taking up the lost motion of their slots, while continued movement from mid-position towards the left releases the brake and puts in the clutch. The brake is actuated gradually through a known form of " follow-up " mechanism in which the opening movement of the valve lever 24 to release the brake is initiated by the downward movement of lever 18 about the pivot 22 and is nullified in part by the pivoting of the same lever about the fulcrum 17 as the brake piston descends. An emergency brake lever 40 can be moved to the braking position shown in dotted lines by straining elastic members 14, thus applying the brakes independently of the position of the lever 3. In a modified arrangement the lever 3 is furnished with cam slots at its lower end which are normal to the links they control for a portion of their length and thus do not rotate them during that part of the travel of the lever. In another modification the lever 3 is provided with a " gate " control in conjunction with a rocking movement at right angles to the shaft 46 to engage selectively with levers taking the place of the links 6, 7. In another modification the lever 3 with cam slots at the lower end is adapted to control the clutch through linkwork and the brake engine through a relay gear. Specification 28849/12. is referred to.

Title: Arrangement in respirators
IPC: A61M16/10
Filed: 1960-09-14
Abstract: 889,164. Artificial respiration apparatus. ENGSTROM C.-G.D. Sept. 14, 1960 [Sept. 16, 1959], No. 31715/60. Class 81 (2). An artificial respiration apparatus using forced inhalation and working on a closed circuit principle incorporates a device, responsive to the total volume of gas in the system, which automatically admits oxygen when the volume reaches a predetermined low level. In the form shown, the mask is connected to conduit 2 and air or other gas is pumped into the lungs by a bellows 4, in conjunction with non- return valves 11, 12. Exhaled air passes through non-return valve 21 and CO 2  absorber 17 to a type of gasometer 30 and thence to the suction side of the bellows 4. The bell 31 is counterbalanced by a weight 37 and, when the volume of enclosed gas has decreased sufficiently the bell descends and a contact 40 is drawn up against a fixed contact 41. This completes an electrical circuit through an electromagnet 47 which opens a needle valve 49 to admit more oxygen from a suitable supply container. The electrical circuit is automatically broken when the volume of gas has increased sufficiently. In a modified apparatus (see Fig: 2, not shown), the decrease in volume is detected by the reduced size of a bellows which mechanically opens the oxygen admission valve. As a further modification, the oxygen admission valve may be replaced by an electricallycontrolled pump for forcing oxygen or other gas into the system. Specification 888,244 is referred to.
