Title: Improvements in method and apparatus for moulding corrugated board and corrugated paper board
IPC: D21F11/12
Filed: 1952-10-20
Abstract: 772,172. Faced corrugated board &c. PACKAGING MATERIALS CORPORATION. Oct. 20, 1952 [Nov. 3, 1951; Nov. 3, 1951; Nov. 3, 1951; Sept. 27, 1952], No. 26256/52. Class 96. In the production of packaging material, e.g. as illustrated in Fig. 21, pulp from a flow box 4 Fig. 1, is formed on a cylinder 1 having a grooved or corrugated surface, subjected to suction of internal boxes 6a, 6b, 6c and 6d, the suction, which is weakest in the first box 6a, acting through holes 3 in the grooves and through an outer, finer wire-cloth and an inner, coarser wire-cloth, both wire-cloths being corrugated, or of zig-zag shape to conform to the shape of one surface of the corrugated fibrous ply 26 to be produced, but not to fill completely the grooves of the cylinder 1. Water is expressed from the web by adjustable, spring-pressed rollers 11, 13, 15, one of which may be ribbed to conform with the grooves of the cylinder 1. On starting, an air blast 10 blows the pulp web 25 off the cylinder on to a conveyer 9 which carries it into a heated-air drying-chamber, a second conveyer below the first taking it out again and directing it to guide rollers and into a gluing &c. appliance where one or two facing plies 81, 83, Fig. 21, are adhered with the aid of heat. The adhesive 82 is applied to the plain plies as spots or as spaced lines transverse to the corrugations, to facilitate bending the finished product. The ribbed parts of the corrugated ply may be scored transversely, or with two sets of scorings each at 45 degrees to the line of the ribs and at 90 degrees to each other. The density and thickness of the corrugated ply 26 are regulated by the pressure applied by the roller 13 &c. In modifications: (1) rollers 11, 13, 15 are substituted by an endless belt pressing on the cylinder 1; and (2) a suction wet press is interposed between the cylinder 1 and the drying-chamber. The corrugated ply 26 may be impregnated with synthetic resin, lignin, or sodium silicate. Specification 704,928 is referred to.

Filed: 1945-10-09
Abstract: 629,236. Knitting. SCOTT & WILLIAMS, Inc. Oct. 9, 1945, Nos. 26307 and 26308. Convention dates, Oct. 10, 1944, and May 31, 1945. [Class 74 (ii)] The heel of a stocking includes two adjacent progressively narrowed gussets 8, 11, the first course of the gusset 11 containing more wales than does the starting course of the gusset 8. Before beginning the gusset 8, more than half the needles are rendered inactive. The gusset is then formed by narrowing at the rate of one needle per course. To begin the gusset 11, all those needles picked out of action whilst making the gusset 8 are restored; but, in addition, on the first stroke of the machine, three additional inactive needles at the trailing end of the active group are picked into action and, on the next stroke, a further three needles are brought into action at the other end of the group; this avoids the formation of eyelets at the heel corners. The gusset 11 is then knitted by narrowing at the rate of one needle per course, contains more courses and more wales than the gusset 8 and is narrowed beyond the wale where gusset 8 ended. A third, preferably widened, gusset 19 may be added, all idled needles except instep needles being restored to action and widening being carried out over, say, six courses before rotary knitting is resumed. A widened gusset 21, corresponding to a high heel reinforcement, may be formed before the gusset 8. The last course of rotary knitting will include the points 16, 17, 18. All needles, except those at the back of the stocking between the point 17 and its fellow on the other side are rendered inactive and the gusset is then formed by reciprocation, widening taking place along the suture line 17, 18 and its fellow. Specifications 246,113, [Class 74 (ii)], and 355,062 are referred to.

Abstract: 482,453. Electric clocks. ALLGEMEINE ELEKTRICITATS-GES. Sept. 30, 1936, No. 26582. Convention date, Oct. 11, 1935. [Class 139] [Also in Group XXXV] In an installation comprising clocks driven by a synchronous generator, current of twice the frequency of that normally supplied to the clocks is derived from the field magnet windings of the generator, being produced by armature reaction, and is applied to set the clocks. For this purpose, the clocks 2 can be disconnected from the generator armature winding 1 by a switch 5, and connected to terminals 6 connected to the generator field winding 3 through a resistance 4. The switch 5 also closes the armature circuit of the generator through a resistance 7. Direct current from the generator is prevented from passing to the clocks by a condenser 8, and the high-frequency current is prevented from passing to the battery 12 by a choke 9. During normal running the high-frequency current may be passed through a resistance 11 by a switch 10, and the switches 5 and 10 and that connecting the clocks to the terminals 6 may be interconnected. The high - frequency current may be amplified in any known way before being supplied to the clocks.

Abstract: 876,835. Automatic feed weighers. OTTO, S. Aug. 6, 1959, No. 26961/59. Class 143. [Also in Group XVII] A machine for packaging nails &c. in containers by feeding them into the latter through a shoot, has means for producing a magnetic field in the shoot to orientate the nails prior to their entering the container. The field is rapidly reversed to de-magnetize the nails to permit them to settle. Nails from a supply 10 are fed by a conveyer 11 to weighing means 14 (not detailed). When the desired weight is reached the conveyer stops and a magnetic dribble feed arrester 13 is energized. The weighing operation is initiated by a container fed by a conveyer 35 contacting a stop 62 which also operates switch means 63. Operation of the switch further causes the nails to be dropped on to a vibrating conveyer 16, energizes solenoids 32 to depress the feed shoot 18 into telescoping relationship with the container, stops the conveyer 35 and sets off a timer 60. Just prior to stopping the conveyer 35, a stop 38 is raised allowing the next container to be carried forward part-way to the filling position. Coils 44 on pole pieces 41, 42 of an armature 45 are energized as the vibrator 16 feeds the nails to the shoot and the current through them is then rapidly reversed to demagnetize the nails in the container. A second timer 61 is set in operation whereby the filled ontainer is agitated for a period by a vibrating table 36a above which it rests during filling, and then the stop 62 is lowered and the conveyer 35 restarted to remove the filled container and feed the next empty container forward. The filled container passes over a finger 105 which causes restoration of the stop 62 to its upper position in time to check the next container.

Abstract: 1343729 Centrifugal separators QUEEN'S UNIVERSITY AT KINGSTON 19 April 1971 [8 May 1970] 27129/71 Heading B2P Heavy and light fractions of a fluid (as hereinafter defined) are separated by supplying the fluid to one end of an annular separating zone formed between two cylindrical surfaces rotating in synchronism; establishing circulation of the fluid in the separating zone in the form of substantially a forced vortex thereby producing vortical separation of the fluid fractions and imparting an axial velocity to the fluid whereby the heavy and light fractions are separated. The term "fluid" is defined as including particulate solids, liquids and gases and mixtures thereof which exhibit properties of a fluid. In Fig. 1, a separator for treating liquid containing fine sediment comprises a stationary outer casing 30, 31, 32 to which are respectively connected, via bearing sections 33, 34, inlet and outlet vortex chambers 35, 36. Mounted within the casing is a rotatable assembly comprising a tubular cylinder 10 connected to vaned hollow conical portions 11, 12 terminating in cylindrical sections 13, 14 which have a number of holes 23, 25 and are mounted in plastics bearing sleeves 26, 27 press fitted in the bearing sections 33, 34. A central tubular support member 17 defines with the cylinder 10 an annular separating chamber 24. The member 17 is connected to hubs 28, 29 between which and the conical portions 11, 12 extend impeller blades 20, 21. The hubs 28, 29 are welded to spindles 15, 16, the spindle 15 being connected to a drive pulley or electric motor. In operation, sediment-containing liquid is supplied to vortex chamber 35. Any gases present escape from the liquid through a venting tube 39. The liquid having acquired angular momentum passes down the holes 23 between the blades 20 which impart further momentum to it so that it rotates at the same anngular velocity as the inner and outer walls of the chamber 24 thus forming a forced vortex. As the liquid moves downwards in the chamber 24, the heavier sediment migrates to and accumulates on the outer wall while the centrifuged liquid passes further down between the blades 21, which extract energy from the rotating liquid, and through the holes 25 into the vortex chamber 36 from which it is discharged under pressure through a pipe 38. The sediment is removed from the chamber when rotating of the separator is stopped. Gases separated out in the chamber 24 escape through passageways 22 formed in the hub 28. To overcome turbulence in the liquid leaving the pockets between the inlet blades 20, a perforated plate may be fitted below the blades upstream of the separating chamber 24. Alternatively, the pockets may be provided with a filling of friction packing held in place by a screen to force the fluid to follow the rotation of the inner and outer walls of the pockets.
