Abstract: 1,265,293. Aqueous waste treatment. CHICAGO BRIDGE & IRON CO. 15 Jan., 1970 [23 Jan., 1969], No. 2115/70. Heading B1C. [Also in Division C1] In an aqueous waste treatment plant comprising an aeration tank 24 having feed points 36 and discharge points 44, means 38 are provided for injecting gas into the liquid in the tank, injection ports 78 being arranged so that the injected gas generates rolls in the liquid having their axes on the bias relative to the general direction of normal flow at that location. The means 38 each comprise pipe sections 75, 76 having the ports 78 and a connecting section 77 which also may be provided with ports. The means 38 can be removed for servicing, by equipment carried on a rotating bridge 42 and connected to a rod 84 and pipe 85, after breaking a connection 86. The plant further comprises an activated sludge settling tank 51, an anaerobic digesting tank 33 and a premixer 30. Raw waste is fed along a line 29 into the premixer where it is mixed with return sludge from a line 31. Effluent from the tank 33 and chemicals for phosphorus removal may be added in the premixer. The mixture from the premixer is fed via a trough 35 and the feed points 36 comprising weir gates (70, Figs. 8, 9, not shown) to the tank 24. After aeration and mixing in the tank 24, the liquid passes to the discharge points 44 comprising weir gates (87, Figs. 6, 7, not shown) and into a trough 45 connected to a pipe 47 leading to the settling tank 51. Sludge from the tank 51 is collected by rotating members 52 and returned along the line 31. Part of the sludge passes to the premixer, and the remainder, via an air lift unit 34, passes to the tank 33 for digestion. The clear liquid from the tank 51 is drawn off under a skimmer ring 48 for further treatment via a trough 49. In an alternative embodiment, the tank is rectangular and has concrete bridges in each of which is embedded an air pipe feeding the injection ports.

Abstract: 1,266,626. Welding by pressure. TRW Inc. 20 Oct., 1969 [21 Oct., 1968], No. 51425/69. Heading B3R. [Also in Division B8] Apparatus for feeding small components, such as welding studs, from one track to two feed passages comprises an escapement body 50, in which is formed a guide channel 52, communicating with a supply track 56 and two spaced passages 60, 62, and a transfer slide 54  for reciprocatory movement in said channel 52 the slide having two openings 72, 74, Fig. 7, spaced apart a distance equal to the distance between each of said spaced passages 60, 62 and said track 56, and a component is held in one spaced passage 60 while a second component is moved by the slide from the track 56 to the other passage 62 so that both components may be discharged simultaneously. The slide 54 is moved to the right by a piston actuated by air pressure and is urged towards the left by a spring. A stop member 92, Fig. 7, is carried in a chamber 94 formed in the body 50 and is normally urged toward the left by spring 100 with its stop-pin 104 projecting into the passage 60 except when the left end of a recess 76 in the slide engages the pin 108 to move the stop member to the right. In operation, when the studs in the welding tools have been welded, the air is vented from the piston via an air valve to enable the return spring to move the piston to the left. A stud 30a is then moved to the left by the slide to drop into feed passage 60 prior to which the stop-pin 104 is released by the recess 76 to hold the stud 30a. The piston 78 is then actuated to move the slide to the right and a further stud 30b which has been received by recess 74 is carried into alignment with the right-hand feed passage 62, whilst the stop-pin has been retracted and air is then applied through passages 120, 122 and the transverse passage 124 in the slide 54 to simultaneously blow the two studs 30a, 30b down the feed passages 60, 62. The escapement body 50 is supplied with studs 32 from a source 10 having a hollow rotating member 20 which picks up studs from an opening 26 and delivers them to a supply track 28. The studs are then fed to welding tools 14, 16 via feed passages 36, 38.
