Filed: 1960-10-26
Abstract: 962,331. Wet presses of paper-making machines. BELOIT IRON WORKS. Oct. 26, 1960 [Feb. 19,1960 (2); March 9, 1960], No. 36806/60. Heading D2A. A divided press arrangement comprises a pair or imperforate rolls acting as a wet press, followed by a suction press roll operating on the felt only. A web W on a Fourdrinier wire-cloth, after passing a suction couch roll 11 with a save-all 13 is couched by a suction pick-up 15a on to a felt 14 which carries it through a suction wet-press nip N, the upper roll of which may be hard rubber-coyered, and have 'blind' holes in its outer surface to receive water pressed out of the pick-up felt 14; such water being returned to the felt at the off-running side of the nip. Conventional felt-washing and wringing devices may thereafter operate on the felt. The web W then passes through a press 25 the upper, suction roll of which has a save-all 28, and the lower roll 27 may be rubber-covered, and through a plain press 36, the felt 39 of which then passes through a suction press 42 to remove a predetermined amount of water from the felt so that it is an optimum condition for removing water from the web at the plain press. In modifications: the upper side of the web W may contact a plain roll of the plain press 36, instead of the wire side as illustrated: there may be an upper and a lower felt passing through the plain press, the lower felt passing a water shower before or after entering a suction press: the shower and the press pressures may be under control of a moisture-detection appliance. An anti-deflection roll is described in which the shaft has a passageway for inflating hollow, resilient rings which surround the shaft and which bear against the inside of the shell of the roll, the pressure within the hollow rings being such that deflection due to nip loading is negligible. This way be used for one or both rolls of the last wet press. The shell may be elastomeric and may be drilled with blind holes. Alternatively press roll shells may be of porous ceramic. Specification 962,332 is referred to.

Title: Process for the treatment of hydrophobic artificial fibres
IPC: D06M15/347
Filed: 1954-12-20
Abstract: A process for preventing the electrostatic charging of hydrophobic artificial fibres, for example, fibres of acetyl cellulose, polyamides, polyurethanes, polyacrylonitriles, and polyesters, consists in impregnating the fibres with a solution or dispersion of a condensation product of an aldehyde containing at least one sulphonic acid group with a polyvinyl alcohol having a molecular weight of at least 10,000, preferably 20,000-200,000. Preferred aldehydes are those of the lower aliphatic or the aromatic series, substituted with 1 or 2 sulphonic acid groups, such as acetaldehyde disulphonic acid, propionaldehyde sulphonic acid, butyraldehyde sulphonic acid, benzaldehyde monoand di-sulphonic acid and toluylaldehyde sulphonic acid.  The products may also contain other radicals, such as acetyl groups, and the polyvinyl alcohol may be reacted in part with unsubstituted aldehydes such as butyraldehyde or benzaldehyde to form acetals.  The sulphonic acid products are insoluble in water, and may either be applied to the fibres as such in an organic solvent or, if an aqueous solution is desired, as a water-soluble ammonium, alkali metal, alkaline earth metal or organic salt.  The solution to be applied may contain, in addition, hygroscopic agents such as glycerol, glycol or polyglycols, softeners such as fatty acid sarcosides, polyethylene glycol condensation products with fatty acids and with fatty amines, condensates of fatty acids with ethanolamines, fatty alcohol sulphates, waxes or mineral oils, or cation-active agents. Fibres so treated are somewhat stiffened and are easily carded after drying.  The applied compound may afterwards be washed out of the fibres to avoid interference with subsequent processes, such as dyeing.  Specification 513,076, [Group IV], is referred to.

Abstract: 524,014. Metallized paper. BECKER, F. G. L. (Sadler, H., and Prey, V.). Dec. 21, 1938, No. 37229. [Class 96] Metallized paper, which may be transparent or translucent, is prepared by distributing in the pulp and coagulating upon the fibres metal particles in suspension in a dispersion or emulsion of one or more synthetic resins which are still plastic in the highest attainable state of polymerization. The metal particles may consist, for example, of aluminium powder, aluminium bronze, or copper bronze. The resins which can be employed comprise the olefines, vinyl esters, ethers, and alcohols, acrylic acid esters, and alkyd resins, which may be used in association with suitable softeners. They are' preferably introduced in the final state of polymerization, but the intermediate or initial products may be added in the hollander, the conversion into the final resin being effected either before or after deposition on the fibres. The coagulation is effected by a salt of a bi- or multivalent metal, and may be achieved, for instance, by soaking the fibre in a solution of an aluminium salt, prior to the addition of the resin and metal powder. The products may be airtight and grease- and water-proof. Specification 511,865 is referred to.

A binary signal shaper comprises two bi-stable circuits 1 1 , 2 1 , receiving periodic reset pulses a (or, as in Fig. 1, not shown, two shift registers 1 1 -1 n  and 2 1 -2 n ), a source of binary input signals d connected to the set inputs of the bistable circuits (or the inputs of the shift registers) the output of each bi-stable circuit or shift register being coupled to the input of respective coincidence gates 4, 5 together with time delayed reset of shift pulses b and the outputs of the gates being applied to the set and reset inputs of a further bi-stable circuit 3. When the input d is " 0 " the output of bi-stable 2 1  is also at " 0 " and accordingly coincidence occurs in NOR gate 5 with the delayed pulse 6 from inverter 6. The resulting pulse from gate 5 sets bi-stable 3 to provide a " 0 " output. Bi-stable 1 1  receives its signal input through an inverter 7 so that its inverted "0" input d provides a " 1 " output interrupted by reset pulses from a but as these pulses do not coincide with the delayed inverted pulses from 6 the NOR circuit 4 is not operated. A " 1 " input signal d operates in a complementary manner to switch the bi-stable 3 to its " 1 " state. The delay between trains a and b determines the minimum delay in output response and in the circuit shown it is half the pulse repetition period. Descrimination is thus obtained from interfering pulses of lower duration than this. Increased discrimination and accuracy can be obtained by increasing the stages in the shift register and increasing the reset and shift pulse frequency.

Abstract: 1,273,154. Multi-orificed extruders. BRITISH UNITED SHOE MACHINERY CO. Ltd. 12 June, 1969 [13 June, 1968; 7 Aug., 1968], Nos. 28116/68 and 37581/68. Heading B5A. An extrusion machine, particularly intended for making potato chips, comprises a container 54, Fig. 1, having a multi-orificed base 56 and in which a piston 35, Fig. 4, is reciprocable to extrude a potato powder/water mix through orifices 58, Fig. 1, the piston being poweroperated to move downwardly in a series of steps of pre-selected length as required by an operator of the machine. The invention also relates to the provision of a knife assembly 66 movable on frame 10 to allow removal of container 54. Drive to the piston is via a worm wheel 28, Fig. 4, internally threaded to engage threaded piston rod 34 and driven by a worm (26), Fig. 2 (not shown), on the output shaft of an electric motor 22. Upper and lower limits of travel of the piston are determined by microswitches 112 and 104 respectively, the former being actuated by a striker 116 and the latter by a cam 110, Fig. 1, mounted at the top of the piston rod. Extrusion is initiated by pressing a button 122, Fig. 4, and the time of extrusion is governed by the setting of a potentiometer knob 120 graduated in lengths of extrudate. An electric circuit is described, Fig. 5 (not shown). The position of the piston is indicated by a pointer 48, Fig. 1, which extends through a slot 46 of housing 44. At the end of each extrusion operation, pressure may be relieved in container 54 by a small upwards movement of the piston. The drive may be pneumatic or hydraulic rather than electric. The extrudate is cut by a knife assembly 66 supported by a member 68 vertically reciprocable on a guide 64. Member 68 is normally biased by a spring 90 to bring knife assembly 66 into contact with the underside of container 54, but may be moved downwardly to bring the arms of a peg 98 into slots 103 of guide 64 thereby maintaining the assemby clear of container 54 when the latter is to be removed or replaced. The knife assembly 66 comprises a circular frame (80), Fig. 3 (not shown), blade members (84), and is rotated over a limited arc by means of a handle (86). Flats (81) on frame (80) are engageable by a bowspring (87) to hold the assembly in alternative rest positions. The base 56 may have orifices formed by a grill-like structure of metal strips.
