Title: Improvements in clarifying aqueous industrial effluents
IPC: C02F1/52
Filed: 1964-12-29
Abstract: Industrial effluents containing suspended solids, e.g. paper fibres, and a surface-active agent are flocculated by treating to change the pH by two units in one direction followed by a change of two units in the opposite direction. Flocculation agents may also be added.  The flocs may be separated by bubbling gases through the treated effluents.ALSO:Waste paper is treated with detergents (surface active agents) and pulped to separate the ink from the fibres.  After dilution, washing, thickening and acidification the pulp is turned into a web.  The effluent containing the ink is treated to change the pH by two in one direction followed by a change of pH of two in the opposite direction and thus flocculate the solids.  The purified water is returned to the deinking stage.

Title: Improvements in or relating to presses
IPC: B21D43/10
Filed: 1968-11-08
Abstract: 1,240,176. Multi-station press. VERSON ALLSTEEL PRESS CO. 8 Nov., 1968 [14 Nov., 1967], No. 53050/68. Heading B3H. [Also in Division F2] A multi-station press comprises a set of die structures 15, co-operating punches 18 and workpiece transfer mechanism composed of housings 52, each with a pair of rods 110, 128, Fig. 10, extending therefrom with gripper jaws 44, 45 and interconnected so that the rod 110 is advanced and the rod 128 retracted to grip a workpiece and vice versa to release it. The press is crank-operated (not shown), in timed relationship with a cam 55 which serves to reciprocate a pair of rods 60, 61. The rod 60 is connected to a feed bar 51, on which the housings 52 are mounted, by a linkage including a bell-crank 76, Fig. 6, to reciprocate the bar. The other rod 61 has an integral rack (92), Fig. 7 (not shown), engaged with a pinion 89 splined to an extension bar 88 of a rod 53 which extends above and parallel to the feed bar 51. The rack and pinion 89, (92) serve to rotate the rod 53 as the rod 61 reciprocates. The feed bar 51 and the rod 53 are connected to reciprocate axially together by means of an annular flange 97 on an extension tube 84 engaging a slotted block 99 on an extension tube 66. The rod 53 is splined to a shaft 154 in each housing, Fig. 10. Each shaft has a pinion 156 to reciprocate the rod 110 and move the jaw 44. The rods 110, 128 are connected by an idler gear 152 and a pair of racks 142. The rack on the rod 128 is spring biased rightwards, Fig. 12 (not shown), to provide a lost motion connection. The rack 147 is similarly mounted. A screw (160), Fig. 9 (not shown), on the shaft 128 engages a contact screw 161 and the engagement or disengagements is used to provide electric control signals to indicate the undersize or oversize of the workpiece. In operation the workpiece is moved from one station to the next by the jaws as the ram descends. An ejector pin 33 raises an anvil 32 in each die structure 15 and the anvil is held by air pressure from a duct 35. At the work station the workpiece is held between a pressureoperated pin 42 and the anvil as the jaws are opened. The punch 41 then forces the workpiece into the die 28. As the ram is raised the feed bar is retracted and the jaws closed. The ejector pin 33 raises the anvil to eject a workpiece into the closed jaws (45a), (46g), Fig. 5 (not shown). The lost motion coupling of the rack on the shaft 128 allows the jaws to be forced apart against spring bias. The press may be used to cold forge bar stock into bearing races.

In an embodiment an indexing plate carries outwardly directed arms each of which has a hook on its underside and the plate is rotatably and vertically movably mounted on a vertical shaft around which are arranged a number of tanks. A frame supporting a printed circuit board is hung on one of the hooks and the plate is indexed so that the board is lowered into each of the tanks in turn. The tanks provide (a) a phosphoric or hydrochloric acid solution dip; (b) a cold water spray; (c) a flux dip; (d) preheating to about 250‹F; (e) a solder spray and vibration in solder immiscible liquid; (f) a water rinse at 150‹F (g) a water spray rinse at 120‹F and (h) a drying air flow. In (e) the board in its frame 8, Fig. 4, is lowered between tracks 19, 20 mounted on a plate 21 supported by rods 22, 23 which extend through the wall of the tank 13 and are connected eccentrically to shafts driven by a motor 24. A bath 34 of heated solder, e.g. 63% tin-37% lead is provided in the bottom of the tank and solder is pumped by pump 26 from the bath 34 through pipes 28 providing nozzles 31 directed downwardly. A heated bath 35 of wax, e.g. polyethylene oxide wax or polyethylene glycol wax or an oil, e.g. peanut oil is provided to float above the solder bath 34. As the board is lowered into the tank 13 solder is sprayed upon both sides from the nozzles 31 and when the board reaches the bottom of the channels 19, 20 a switch is operated to cut off the spray from the nozzles. The motor 24 is energised to cause the board to be vibrated in a circular or elliptical orbital path while in the heated bath 35 for 15-20 sees. The orbital motion is stopped and the board is lifted from the tank or alternatively the orbital motion may be continued as lifting proceeds. The board may be wholly coated with solder before it is immersed in the wax bath and the tanks may be arranged in a row.
