Title: Treating impure liquids
IPC: C02F1/00
Filed: 1950-07-06
Abstract: 692,100. Treating sewage; gravity-separation apparatus. DORR CO. July 6, 1950 [Aug. 26, 1949], No. 16883/50. Class 111 In a process which comprises maintaining a constantly-changing body of liquid from which sediment deposits and from which clarified effluent at a fixed level is released, maintaining within the body a zone of agitated flocculation shielded sidewise from the surrounding body of liquid and having a restricted bottom outlet to the main body, and collecting settled solids from the bottom of the body to a region aligned with the restricted outlet, all e.g., as in Specification 537,469, a collecting trough is located between the confining wall of the body and the settled solids collecting region and incompletely-flocculated solids are returned from the trough to be mixed with incoming liquid so that they are re-flocculated in the flocculation zone. Combined flocculation and sedimentation apparatus for carrying out the above process comprises a sedimentation tank 10, Fig. 1, having a central sludge sump 19 and discharge 40, an open-bottomed flocculation compartment 20 formed by a partition 21 within the tank 10 and containing flocforming and coagmenting means such as cylindrical aerators 35, arranged along the four sides of a square, an inlet pipe 13, 14 for supplying incoming raw liquid to the flocculation compartment and travelling rake means 47, Fig. 5, its characteristic features being an auxiliary sludge trough 18 for the outer lighter sludge and a pipe 25 and air-tube 29 for reconducting the sludge thus collected into the flocculation compartment for re-flocculation therein. The pipe 25 and air tube 29 together constitute an air lift, the upper end of the pipe 25 being at the level of apertures 15, Fig. 5, through which the raw liquid passes from pipe 14 into the flocculation chamber 20. Thus the solids in the raw liquid are flocculated and the re-conducted solids are re-flocculated together. In the embodiment shown diagrammatically in Fig. 1 the pipe 25 and partition 21 are fixed while the upper part of the pipe 14 rotates with the sludge scraper arms under a fixed cap (not shown). In Fig. 5 the pipe 225, pipe 14 and partition 221 forming the flocculation compartment all rotate with the scraper arms 45. The lower end of the pipe 225 travels along the trough 18. In each case the returned light sludge fraction may be separately aerated for a time before it is returned to the raw sewage. The tank may be rectangular rather than round.

Title: Improvements in electrical signalling systems
IPC: H03G11/04
Filed: 1927-06-25
Abstract: 297,709. Gage, E. G. June 25, 1927. Atmospherics and undesired signals, eliminating ; thermionic relays; thermionic detectors.-In means for separating desired from undesired electric. currents in which the received currents are fed to two circuits with outputs in opposition, one circuit being unable to reproduce a wave train of the desired frequency on account of ` fatigue ' effect, a thermionic valve is employed in each circuit and the efficiency is enhanced by repetition through a feed-back arrangement. Signals received in a circuit 1 are transferred through a current-limiting circuit 3 - - 6 and a full-wave rectifying-system 8, 9 to the two opposed circuits containing valves 15, 16 respectively. Grid-biasing batteries 13, 14 are adjusted so that no plate current flows when no signals are received. High-tension for the valve 15 is obtained from a storage condenser 22 fed through a rectifier 18 and storage condenser 19 and smoothing circuit 20, 21 from an alternator 17 having a frequency less than that of the desired signal. Signals of the desired frequency exhaust the high-tension supply to the valve 15 which then ceases to oppose the valve 16, and signals appear in the output circuit 32, but irregular atmospherics do not exhaust the high-tension supply and are therefore eliminated by opposition between the output of valves 15, 16. 'The effect is enhanced by means of a feed-back circuit 34 - - 37. Specification 258,635 is referred to.

Title: Improved safety device for use with pressure vessels
IPC: F16J13/24
Filed: 1943-10-21
Abstract: 570,308. Doors for resisting fluid pressure. FOSTER, YATES, & THOM, Ltd., and LOUSLEY, N. W. Oct. 21, 1943, No. 17361. [Class 123 (i)] [Also in Group XXIX] The door of a pressure vessel is operated by a hand wheel a which, by an axial movement, is clutched at f to a gear-wheel e engaging a pinion which gears with a rack q carried by the door, whereby the door is rotated and lugs carried by it engage or disengage corresponding lugs on the vessel. The axial movement of the hand wheel is obtained by means of a threaded extension d<1> of its spindle which screws into an extension g of the gear-wheel e and thereby expands the collet f. The hand wheel a overlaps a hand wheel j which operates a pressure release valve so that the latter can only be closed when the door is closed. The hand wheel j overlaps a hand wheel n controlling a pressure valve so that this valve can only be opened when the release valve and door are closed. Further, the door can only be opened when the exhaust valve is opened and the pressure valve closed. The pinion between gear-wheel e and rack q is toothed around its periphery where it engages wheel e, but only around part of its periphery where it engages rack q. so that it disengages when the door is closed and further rotation of the hand wheel a allows the fully-toothed part of the pinion to engage a rack u, connected to the door by a pin and slot, whereby a projection v engages the stem w of a valve x controlling a steam whistle, to close the valve. The first movement of gear-wheel e on opening the door releases valve x so that the whistle sounds if any steam reaches it by the byepass 2 from the steam valve, or any pressure remains in the vessel, or the release valve is not fully opened or steam valve fully closed.
