Abstract: 934,146. Activated sludge processes. ACTIVATED SLUDGE Ltd. Oct. 7. 1960 [Oct. 8 1959], No. 34065/59. Class 46. The three aerobic treatment stages, marked respectively stage 1, stage 2 and stage 3, are of similar construction although not necessarily of equal capacity, and each stage comprises a tank divided into an agitation zone 10 and a sludge separation zone 11 separated by a vertical division wall 12; while communication between stages is by weir 21. Communication between agitation section and the sludge separation section, for the return of sludge as hereinafter described, is provided by a narrow section 13 formed by a wall 14 located fairly close to the wall 12. Porous stone or other air diffusers 15 are located adjacent the bottom of the agitation section 10. An opening 16 provides communication between the upper parts of sections 10 and 11, this opening being associated with deflectors or baffles 17, and 17a to prevent short circuiting. There is also a baffle 17b at the inlet to direct the sewage or other waste liquor to the lower part of the tank 10. The sludge separation section 11 has a sloping bottom so that the separated sludge is directed towards a sludge return opening 19 and the diffusers 20, which are under manual control, are used to control the amount of sludge returned. There may be more or less than three stages before purified effluent is discharged at 24. In other modifications (not shown) the tanks are of circular cross section and the levels of aerators 15 and 20 are different.

Title: Machine for making tube of plastic strip material, progressively filling the same with fluid and dividing the filled tube into containers
IPC: B65B9/20
Filed: 1966-07-29
Abstract: 1,103,747. Making plastic tubes. H. M. HAYWARD, and L. A. HUMPHREY. 29 July, 1966 [2 Aug., 1965], No. 34075/66. Heading F2P. [Also in Division B8] Tubing is fed downwardly through a machine for making satchets by a pair of feeding clamps 66, 67 (Fig. 8), joined for simultaneous reciprocation, and liquid is pressed upwardly by the upper clamp 66, and then sealed off by rollers 104, 104a to leave space for formation of a tranverse weld by means 47 mounted between the clamps. The tubing is formed about a mandrel (24) (Fig. 9, not shown), for example by forming and guiding dies (23a), (23) which form an overlap, and the tube is welded longitudinally by a reciprocating high-frequency electrode (32). The upper clamps may comprise members 98 (Fig. 3), geared together for conjoint pivoting about shafts (99) by a ram (101). An extra increment of feed to bring printing on the tube into proper registration may be provided by the rollers 104, 104a (Fig. 3). The rollers are carried by a pair of arms 102 geared for conjoint pivoting about the shafts (99) by a further arm (115). The rollers, which are connected by lugs 105, 105a for conjoint rotation, are turned, at the bottom of the downward stroke of the clamps, when a lug 109 on one of the rollers engages a stop 110 which is adjusted by an operator to provide the required increment. Before this action takes place the levers 102 have been swung together, and the clamps 98 swung apart. The stroke of the feeding clamps, and the distance between them, can be altered. Removable and replaceable caps (133) (Fig. 9, not shown), may be welded to the tubing, before it is filled, by rotary welding heads (134) which also convey the caps from a conveyer 144. Apertures may be pierced in the tubing before the caps are applied. The machine may form and fill two tubes simultaneously. A guillotine 68a (Fig. 8), carried by the lower clamp 67 may cut the satchets from the tubing.

Title: Improvements in or relating to wire fencing
IPC: E04H17/10
Filed: 1920-12-03
Abstract: 174,270. Swingler, E. Dec. 3, 1920. Wire fencing, securing to standards; fencing- posts. - Relates to a method of erecting wire fencing, to the construction of posts therefor, and to a method of jointing free ends of the wires within the posts. Metallic ferrules 1, Fig. 1, are cast within concrete posts at suitable points to take the wires 2, which are drawn taut at each post or over a number of posts, and wedges 3 driven into the ferrules to grip the wires. A joint at a post is effected by means of a wedge 3, Fig. 14, holding the two overlapping ends of the wire 1, 12 together. Turning of the fencing is carried out by means of a corner post with two sets of ferrules at right-angles. In the application of the invention to wooden posts, borings are made in each side of the post, one 8, Fig. 7, to take the ferrule and the other 9 through which to thread the wire; the wedge 10 has longitudinal ribs 11 which bite into the material of the post and prevent turning. Fig. 9 is an end elevation of the ferrule shown in Fig. 7. The metal lining may be tapered so that the wedge is inclined out of the line of the wire, providing an additional grip; or a cylindrical sleeve hammered out at one end to provide an elongated shape may be used.

Abstract: 496,009. Knitting- machines. HEMPHILL CO. Dec. 15, 1937, No. 34717. Convention date, Dec. 28, 1936. [Class 74 (ii)] Jacks 146 each having removable patterning butts 148 and a cam-actuated butt 152 are provided beneath the sinkers 142, and pattern controlled plungers 110 are arranged to engage the butts 148 to raise the jacks to a position in which the butts 152 can be engaged by the cam 183. The butt 152 is inclined so as to engage a correspondingly inclined surface on the cam 183 so that the jack is maintained in a raised position. The plungers 110 are slidably mounted and are spring-pressed towards the sinker jacks. Pivoted members 89 have end portions 112 engaging recesses 111 in the plungers, and are actuated by stops 90 on a pattern drum 11 to withdraw the plungers from operative position. A pattern controlled roller 125 with flattened side 126 is provided for holding all the levers 89 away from the pattern drum 11 so that all of the plungers are rendered inoperative. To permit patterning to be suppressed in part of the fabric, e.g. the foot of a stocking, the jacks 146 corresponding to the unpatterned part have butts 150, and the pattern drum 11 has a complete row of stops 90 to engage the plunger 110 corresponding to the butts 150. Alternatively, the top butt 148 may be used in place of the butt 150. In operation, the jacks 146 are moved outwardly for selection by the plungers 110 by a cam 172, Fig. 7, and maintained at the correct level by cams 174. The jacks selected by the plungers are engaged by the bevelled side of a dividing cam 180 and are moved inwardly to a position for engaging the cam 183. The cam 183 pushes the jacks and sinkers inwardly for, e.g. reverse plating. Thereafter, the jacks are engaged by a cam 184 and are moved outwardly and downwardly to join the unselected jacks. Specifications 344,486, 442,836, and 496,032 are referred to.
