Title: Improvements in and relating to machinery for making mill or pulp board
IPC: B31C1/00
Filed: 1942-02-10
Abstract: 553,811. Pulp board making-roll; clutches. HAMILTON, A., and JACKSONS' MILLBOARD & FIBRE CO., Ltd. Feb. 10, 1942, No. 1751. [Class 96] [Also in Group XXIV] The making-roll 1, Fig. 4, upon which plies are wound in the production of pulp- or millboard is grooved at 12 or along a longitudinal severing- bar 7, to produce a line of weakness in the pulp along which rupture occurs when the bar 7 is thrust outwardly as by springs, centrifugal force or gravitation, at a pre-determined thickness or after a given number of plies have been wound. The bar 7 is held retracted, as shown, during winding, by cams 16 and rollers 19 &c. as long as the roll 1 is keyed to its shaft 3 by a clutch, Fig. 2. The clutch comprises a barrel 23 keyed to the roll-shaft 3 and within a sleeve 24 keyed to a collar 25 secured to the end plate of the roll 1. The sleeve 24 and barrel 23 are grooved to receive the clutch pin 27 which at the completion of winding is turned, by the actuation of a sear 32 and the spring and lever mechanism illustrated in Fig. 2, so that a recess in the pin 27 permits the roll to continue to turn whilst the shaft 3 is stopped thus allowing the cam-follower rollers 19. Fig. 4, to descend the cam-declivities 17 to release the bar 7 and sever the pulp sheet. The sear 32 is actuated by a sliding vertical bar 41 which is moved downwardly as the thickness of the wound sheet increases and the roll shaft moves upwardly, a lever 39 magnifying the movement. On removal of the severed pulp board, the roll 1 descends, and its continued rotation re-sets the cams and springs, retracts the bar 7 and allows the clutch pin 27 to turn, whereby the roll 1 is again coupled to its shaft 3.

Patent GB-222294-A (GB)
Title: Improvements in automatic weighing apparatus for liquids
IPC: G01G13/00
Filed: 1923-08-30
Abstract: 222,294. Simpson, J. R. H. Aug. 30, 1923. Automatic - feed weighers.-An automatic weighing - apparatus for liquids and particularly for sugar juices comprises a pair of balanced receptacles into which a surplus quantity of liquid is passed alternately, the supply: of liquid being diverted automatically from one receptacle to the other when the contents of the first receptacle is discharged automatically, the surplus liquid being discharged automatically and serving to actuate the liquid supply means so as to divert the supply of liquid from one receptacle to the other. Two receptacles 6 mounted on counterbalanced weight-beams 5 are arranged side by side and are supplied alternately with the liquid by means of a pipe 11, pivoted tube 10 and a divided hopper 8. Assuming the right-hand receptacle, Fig. 1, to be filling, the increasing charge causes the receptacle to fall, but as the feed of liquid continues an overweight is received. A rod 58, Fig. 4, descending with the receptacle. is arrested by a stop on the frame and opens a valve 57, allowing the surplus liquid to run out into a bucket 18 suspended from one arm of a lever 14, Fig. 1, the other arm supporting a similar bucket 17 used in connection with the left-hand receptacle. The liquid in the bucket 18 rocks the lever 14 and thus turns the feed tube 10 so as to direct the feed into the left-hand receptacle. A hole 20<a> in the overflow of the bucket 18 allows the contents to run out for return to the source of supply. During the downward movement of the right-hand receptacle a roller thereon pushes back a sliding catch on the lefthand receptacle and thus allows the discharge valve of the left-hand receptacle to fall into the closed position. When the weigh-beam rises, due to the loss of the surplus liquid, the valve 57 closes and a block on the weigh-beam presses upon the lower end of a lever 44, Fig. 4, pivoted on a weighted lever 43, and throws the weighted lever into the horizontal position shown. The weighted lever, acting through a link 42. sleeve 34 and spring 37 raises a rod 24 and opens the discharge valve 23 of the weighing-receptacle. During the further upward movement of the weighing-receptacle (retarded by a dash-pot), a roller 63 restores the weighted lever 43 to its former vertical position, where it is retained by a catch 52. A similar cycle of operations takes place in connection with the left-hand receptacle. In a modified arrangement the discharge valve 23 is opened by a solenoid the circuit of which is closed by the upward movement of the weighing receptacle.

Title: Production and spinning of polyamides from caprolactam
IPC: D01D1/10
Filed: 1951-01-26
Abstract: <PICT:0731664/IV (a)/1> <PICT:0731664/IV (a)/2> Caprolactam is polymerized in a tube 1 or alternatively in a closed vessel 2 and the molten polymer taken by pump 3 via a filter 4 and pumps 7 to vacuum vessels 8 kept at polymerization temperature, the polyamide being further polymerized therein while monomeric lactam is removed via the tubes 9.  A constant liquid level is maintained in the vacuum vessel by means of an electrically conducting ball which floats in the polyamide melt but sinks in the foam above the melt.  When the melt is at the required level the ball makes contact with terminals in the vessel to control the motor driving the pump 7.  The melt is removed from the vessels 8 by screw conveyers 24 having rapidly diminishing pitch which by raising the pressure assist in removing bubbles from the melt.  In the vacuum vessel as large a surface as possible of the melt is offered, either by passing the melt through the vessel in the form of filaments or by flowing it down spiral trays (Figs. 4 and 5, not shown).  From the screw conveyers pumps 11, 13 conduct the melt to spinnerets 14.  In examples (1) caprolactam with 10 per cent water and 0.28 per cent acetic acid are reacted at 260 DEG  C. while allowing escape of steam in a closed vessel.  The vessel is then filled with nitrogen to 4-5 atmospheres pressure and the polymer, containing 11-12 per cent monomer, taken to the vacuum vessels of Fig. 1.  After 30 minutes in the vessels at 250 DEG  C. the polymer is free from monomer and polymerized to the required degree.  After spinning the monomer content is 2-3 per cent. (2) Caprolactam with 1 per cent water and 0.27 per cent acetic acid is led into a heated tube having three sections at 180 DEG , 240 DEG  and 260 DEG  C. in which it is polymerized for 20 hours.  The polymer, with a monomer content of 11-12 per cent, is treated as in example (1). Specifications 666,378 and 693,376 are referred to.
