Title: Method of applying liquid addendum to opposite surfaces of a continuous multifilament tow
IPC: D04H3/14
Filed: 1965-12-20
Abstract: A cylindrical tobacco smoke filter rod is made from a tow of crimped continuous filamentse.g. of a denier less than 3 - by forming the tow into a band or ribbon, subjecting the band to tension sufficient to remove the secondary crimps therefrom, separating the filaments by longitudinally displacing portions of the tow with respect to adjacent portions, spreading the tow to a uniform constant width by means of a banding jet supplied with high velocity gas, applying a thin uniform coating of plasticizer to one or both surfaces of the spread tow, further separating the filaments and uniformly distributing the plasticizer therein by means of a gas jet and finally shaping the tow into a cylindrical form in which the filaments are fused to one another at random points by the action of a plasticizer. The filaments are displaced longitudinally by being passed between a bottom resilient surfaced roller and a top grooved roller pneumatically pressed against the bottom roller. The top roller has continuous or interrupted circumferential square-form cross-section grooves. The plasticizer is applied by means of rotating rollers -Fig. 2 (not shown) - which ares supplied with the liquid plasticizer by means of wicks connected to a plasticizer reservoir fed by a metering pump. The plasticizer may be triacetin, if the filaments are composed of cellulose acetate. To increase the removal of the phenol component from tobacco smoke, a high molecular weight polyethylene glycol liquid additive may be used to coat one side of the tow instead of the plasticizer. After the plasticizer has been uniformly distributed in the tow but before the cylindrical rod is formed particulate material - e.g. activated carbon, sodium bicarbonate, rice starch, cellulose acetate floc - may be added to the tow.

Title: Fibrous Thermoplastic Material
IPC: D01D5/42
Filed: 1967-04-24
Abstract: A fibrous thermoplastic material is made by forming a thermoplastic mass containing gas bubbles, bursting the bubbles by heating the mass and stretching the mass. Preferably the material is formed by extruding the bubble-containing thermoplastic mass through a heated die so as to burst the bubbles then stretching the extrudate after it has left the die. The bubbles can be introduced by use of a gaseous, liquid or solid blowing agent, e.g. sodium bicarbonate, azodicarbonamide or dinitropentamethylenetetramine or by injecting a gas under pressure into the thermoplastic mass. The mass can be polystyrene, acrylonitrile-butadiene-styrene copolymers, acrylonitrile-styrene copolymers, poly vinyl chloride, polymethylmethacrylate or polyethylene or a mixture thereof. The mass may also contain a paraffin oil. The extrusion die can be flat or circular, e.g. to produce sheets or tubular articles and heated to at least 180 C. to burst the bubbles. The stretch ratio can be 3 : 1 to 6: 1 in the axial and transverse directions in relation to the longitudinal axis of the die. The fibrous sheets formed can be shaped with or without heating. A polystyrene fibrous product has a density of 0À3-0À6 g/cc. and may be 0À3 to 0À8 mm. thick or 2 to 3 mm. thick.

Patent ES-359404-A1 (ES)
Title: Variable delay circuit
IPC: H04Q11/04
Filed: 1968-10-22
Abstract: A variable delay circuit receives a stream of PCM channels and delays it until it synchronizes with a transmitted PCM multiplex frame, the synchronizing being effected by generating a pulse PIN on detection of a synchronizing channel in the received PCM stream and passing this pulse along a delay line SR1 the point reached by the pulse PIN, when the synchronizing channel appears in the transmitted PCM stream and gives rise to pulse P REF , being marked to indicate the delay required the received PCM stream being passed along a delay line SR2 to be tapped off at that point corresponding to the marked point of SR1. The delay lines are stepping registers and follow a fixed delay D. Each stage of SR1 has an associated bi-stable B set by coincidence of PIN in a stage of SR1 and P REF . The set bi-stable B gates the digit stream out of the corresponding stage of SR2. To make sure that pulse PIN is wide enough to be entered in at least one stage of SR1 it must from time to time enter two consecutive stages. To prevent the consequent setting of two bi-stables B from gating the digit stream from two points of register SR2 the connections between bistables B and gates G11 to G15 are such that, as shown in dotted lines, the gates can be opened by a reset followed by a set bi-stable and not by set followed by set or set followed by reset bi-stables. The variable delay is employed in the looped telecommunication system described in Specification 1,187,488.
