Abstract: 769,981. Pyrotechnic apparatus. STADA (nee BEEN), F. and PIETERMAN, J. VAN DE. May 16, 1955 [May 28, 1954], No. 14122/55. Class 9 (2). A device for discharging flares and like signals comprises a rotatably mounted disc 3 carrying radially disposed flare holders 4. A cam roller 7, Figs. 2 and 4, driven through gear wheel transmission by a rocking weight 5, has cams 8 co-operating with hammers 9 to drive striking pins 11 through openings 12 in the holders 4 to fire the flares successively. When a radial row of flares has been discharged the disc 3 is rotated to bring the next row of flares to the firing position. The roller 7 has at one end a stepped portion forming a recess receiving a disc 16 rotatably mounted on an arm 17 projecting from a rotatable shaft 18. As the roller 7 rotates, it displaces the arm 17 thereby moving a lever 23 and so displacing a locking pawl 19 carried by the shaft. A projection 20 on the pawl is thus moved out of engagement with the disc 3. A spring 26 then moves an arm 25 to rotate the shaft 18, which then drives a ratchet 29 through an arm 27 and rod 28 to rotate a wheel 31 rigidly connected to the disc 3. The disc 3 rotates until re-engaged by the pawl 19, bringing the next row of flares to the firing position. The rocking weight is locked by arms 33, 34 carried by a rotatable shaft 35 which is locked by a pawl 36. The weight may be replaced by a spring driving mechanism.

IPC: D02G1/00
Filed: 1969-03-18
Abstract: 1,254,923. Crimped multifilament yarn. SOC. RHODIACETA. 18 March, 1969 [18 March, 1968], No. 14296/69. Headings D1F and D1W. A textured multifilament polyester yarn is characterised in that the individual filaments have substantially zero twist torque and a crimp in the form of rounded castellations (as distinct from saw-tooth crimp), the filaments being generally loosely interconnected. A process for producing the yarn comprises partially stretching a multifilament yarn of a synthetic thermoplastic material in contact with a crackpromoting agent, giving the yarn a heat treatment in a relaxed condition, and knitting, setting and deknitting the yarn. In a preferred embodiment the setting step between the knitting and deknitting steps constitutes at least part of said heat treatment. The first part of the heat treatment is preferably effected under conditions of thermal shock. The partial stretching and heat treatment of the yarn may be carried out as separate operations or as a continuous process. In a preferred embodiment of the process, the yarn is partially stretched in contact with a crack-promoting agent, e.g. an aqueous solution of a lower aliphatic alcohol, is knitted into a strip and the strip is rapidly immersed for a short time in boiling water, and then heated for several minutes in hot air or steam, after which the strip is deknitted. After the initial partial stretching and heat relaxation step, the yarn may be subjected to a supplementary stretch and relaxation treatment, during at least one of which or during the initial partial stretching, the degree to which the length of yarn is being altered is varied regularly or randomly. The yarn treated is preferably of polyethylene terephthalate.

Title: Sewage treatment
IPC: C02F1/52
Filed: 1973-03-28
Abstract: 1369381 Sewage effluent treatment with a chemical reagent and a surface active agent SIMON ENG Ltd 28 March 1973 [28 March 1972] 14414/72 Heading C1C Sewage effluent is treated by (i) adding a chemical reagent to produce one or more of the following effects, namely precipitation, flocculation and adsorption, (ii) removing the faster settling solid particles by sedimentation, (iii) adding a surface active agent to render the remaining solid particles hydrophobic and, if the surface active agent is itself not a frothing agent, also adding a frothing agent, and (iv) passing the mixture downwardly and countercurrently to a stream of fine gas bubbles to remove suspended solids and other pollutants with the foam produced. Thus, the effluent, which may be a raw sewage effluent or one obtained by primary or secondary treatment of such an effluent, may be passed via a conventional screening and grit removing device to a tank provided with a motor driven agitator and a probe for measuring pH, said probe controlling a dispensing mechism for delivering chemical, e.g. lime, from a hopper to the tank. After attaining a pH of at least 11 the contents of the tank are passed to a settling tank for a retention time of about 15 minutes, and the liquid from which faster settling particles have been removed is mixed with, for example, an anionic surface active agent such as an alkyl arylsulphonate and then introduced into the upper end of a vertical column for downward flow therethrough countercurrently to a rising stream of fine air bubbles from an air diffuser supplied with compressed air at the base of the column. Liquid collected at the base of the column is introduced to the upper end of a second similar column, and from both columns foam is collected at the top and passed to a centrifuge via a foam drainer, and the liquid recovered from the centrifuge and drainer returned to the main process stream upstream of the first column. Conveniently sludge from the settling tank is also passed to the centrifuge. Solids from the centrifuge are burnt in an incinerator. The final effluent from the base of the second column is very low in suspended solids, e.g. 0-15 p.p.m. from typical raw sewage liquors. When using the new process for tertiary treatment aluminium sulphate is the preferred reagent. The use of alums necessitates the use of a cationic surface active agent. The final effluent can be further treated by conventional processes.

Title: Improvements in or relating to bundle wrapping machines
Inventor: SYKES THOMAS ROBERT
IPC: B65B27/08
Filed: 1957-08-27
Abstract: 878,769. Feeding webs. TORONTO STAR Ltd. Aug. 27,1957, No. 14419/61. Divided out of 878,768. Class 100(1) [Also in Group XVII] In a wrapping machine, a supply of wrapping paper 20 is provided below a conveyer, A, B, C. Rollers 8, 25, feed a web of the wrapping paper up on to the conveyer, from withdrawable carriers 54 each holding a roll 20, 21, of wrapping paper so that when one roll 20 is exhausted a fresh roll 21 is already in position for feeding into the machine. The wrapping paper passes up between guide means 23, 24, then through gripper means 29, 50, Fig. 6, and finally between the rollers 8, 25, the roller 25 being displaceable from the roller 8 about an axis 26. As the forward edge of a bundle reaches the upper edge of the wrapping paper between the rollers 8, 25, it also contacts a switch arm 31 (Fig. 1, not shown) and this switch causes a pneumatically operated piston 28a, Fig. 6, to move the roller 25 towards the roller 8 to grip the paper therebetween and, at the same time, to open the grippers 29, 50. The driven roller 8 then draws the paper from the supply and feeds it along the conveyer beneath the bundle. When the bundle has passed a switch 30 (Fig. 1, not shown) the return movement of the switch 30 causes a piston operated rack 33a to move forward from the position shown in Fig. 6. The rack 33a is geared to a pinion which, on rotation, causes a cutter bar 38 to swing over the roller 8 and then down against a saw-toothed knife edge 39 below the paper 19 to cut the paper. Continued forward motion of the rack 33a causes it to engage a press button 42a of a switch 42 to cause (a) the cutter bar 38 to return to its original position, (b) the roller 25 to move away from the roller 8 to prevent further feed of the wrapping paper and (c) the grippers 29, 50, to close to prevent the paper from being withdrawn from between the rollers 25 and 8.
