Title: Wastewater treatiment system with controlled mixing
IPC: C02F3/16
Filed: 1974-11-12
Abstract: 1438749 Aerating liquids AIR PRODUCTS & CHEMICALS INC 12 Nov 1974 [12 Nov 1973] 48863/74 Heading B1C In a method of oxygenating waste water the liquid flows through a closed unpartitioned aerator vessel 10 having a plurality of surface aerators 71, a gas containing not less than 50% oxygen is supplied thereto, and the aeration mixing factor ND/U is maintained in the range 10-550, where N is the number of revolutions per minute of the surface aerator, D is its diameter at the liquid surface, and U is the linear flow rate of the liquid. In these circumstances the system operates as if the liquid were separated into a plurality of distinct treatment stages. The aerators may be vertically adjustable and their shafts 72 may also carry stirrers 78 to keep the solids in suspension. There may be "gas baffles" 60 separating the atmosphere of the treatment stages; gas may pass from one stage to the next through apertures in the baffles 60 or through conduits 64 having control valves 66, and the gas may be discharged through a conduit 50 having a valve 52 controlled by an oxygen sensor 54. There may also be baffles 80, 80a in the surface region of the liquid; they may be fixed or adjustable, and be associated with a face part of a gas baffle 60. The apparatus dischages into a settling tank 30 whence activated sludge may be recirculated to one or more inlets. Influent liquid may be introduced through conduit 22 to one or more treatment zones. The linear flow rate may be altered by varying the rate of inflow or the flow rate of recycled sludge; in systems subjected to widely varying uncontrolled flow rates, each surface aeration may be replaced by a plurality of surface aerators of different diameters which may be operated independently, separately or together. The aerating vessel may have zones of complete mixing upstream or downstream of zones which are effectively separate stages; there may be a plurality of vessels in series.

Title: Apparatus for preventing drunken driving of a motor vehicle
IPC: B60K28/06
Filed: 1972-10-24
Abstract: 1401318 Preventing drunken driving HONDA GIKEN KOGYO K K 24 Oct 1972 [27 Oct 1971] 49054/72 Heading G1N [Also in Division B7] Alcohol exhaled by a vehicle driver is detected by a device past which air from within the vehicle is drawn by a pump, the device preventing the vehicle being driven when alcohol is detected, e.g. by breaking the ignition circuit. The pump may be fitted with a pressure sensor which also prevents the vehicle being driven should the driver try to block the air intake. In Fig. 1 the pump 1 draws air from adjacent the steering wheel past alcohol detector 8 and pressure sensor 17. Dector 8, Fig.3, is a heated platinum wire fed from D.C.-A.C. converter 9; alcohol vapour burns on the wire, changing its temperature and its resistance. As the resistance changes the potential at tap 10a of potentiometer 10 varies, and transistor 12 is switched on. This operates relay 13 to illuminate warning light 15 and to disconnect ignition circuit 14. The pressure sensor is a diaphragm controlling switch 18. Relay 13 is self-holding, but may be reset by switching off ignition switch 19 when a sober person is to drive.

Abstract: 1493146 Wire stripper P ROTH 14 Nov 1974 [20 Nov 1973] 49398/74 Heading H2C A wire stripper comprises an upper pivotable surface 15 longitudinally movable relatively to a lower fixed surface 3, each surface having long and short gripping sections 4, 5 and 16, 17, as shown, and a knife 7, sharp at the right-hand end and the remainder blunt, is located in a slot between the lower gripping sections 3, 5. A cable inserted up against a stop 11 on the right is rolled to the left with the last part of the movement, after the cutting of the insulation, resulting only in rotation and removal of the cut end of the insulation while the remaining part slides between smooth surface sections 20, 21. A roller 18 prevents full closure of the surfaces 3, 15 and a disc 8 enables adjustment of the height of the knife 7. In a modification (Figs. 2-4) the upper and lower surfaces (22, 23) are simultaneously movable in opposite directions so that the cable stays put rotating about a stationary axis. Subsequently spring biased gripping elements (47, 48) automatically draw the bared wire out of the device. Movement of plates carrying the upper and lower surfaces (22, 23) may be effected by a single or endless thread (37) or by toothed racks. The gripping sections may be file like elements or parts of driven wheels and the knife may be associated with an electric heating element.

Chamber 6 engages poppet 20 on driving unit 21 mounted on shaft 22 of trolley 23 which travels on rollers 24 movable along trolley 25 itself mounted on rails 26. Parts 28 to be welded are between mobile poppet 20 and tail stock 29 fixed to door 30 actuated by jack 31 and rod system 32. Displacement device 3 allows limited gun movement to effect additional welds. A fresh identical part may be substituted via door 30, which substitution of parts of different sizes and shapes requires withdrawal of chamber 6 by the trolleys. Articulation of device 21 about shaft 22 permits orthogonal positioning (Fig. 3, not shown) so that the parts to be welded are rotated about an axis parallel to the beam axis, rather than perpendicular thereto as in the position of Fig. 1. The combination of axial and radial welding is mentioned. The valve 5 is described in detail (Figs. 5-7, not shown) (see Division F2). Gun and buffer chamber pressures may be 10<SP>-5</SP> torr and 10<SP>-2</SP> to 10<SP>-3</SP> torr respectively, while spigot 12 may be associated with optical means allowing examination of the welding operation by viewer 13.
