Patent GB-360372-A (GB)
Abstract: 360,372. Moulding pulp. SOC. INVENZIONI BREVETTI ANON.-TORINO, 8, Corso Vittorio Emanuele, Turin, Italy.- (Assignees of Mackay, A. ; Asbury Park, New Jersey, U.S.A.) July 29, 1930, No. 22848. Convention date, Jan. 11. [Class 87 (ii).] In the manufacture of fibrous sheet material in which a suspension of fibres in the form of a slurry is deposited on a reticulated conveyer where the water is extracted to form sheet material, the slurry is deposited on the surface of a reticulated member travelling in superposed relation to a reticulated conveyer of coarser mesh. The invention is described with reference to the manufacture of artificial leather from an aqueous dispersion of fibres obtained by the disintegration of scraps and cuttings of leather and hides. The apparatus consists of a machine of known type having a conveyer of wire fabric of relatively coarse mesh, and means for superposing above the wire conveyer a band of fabric such as cheese cloth, the latter having its own carrying rollers and drive. The apparatus comprises a conveyer 1, supported on rollers, and suitably driven. A deckle strap 2, a breast roll 3, and a couch roll 4 are provided. The liquid of the slurry is extracted by suction boxes 6. Over the conveyer 1 and in contact therewith on the upper run is an endless belt 7 of textile material such as cheese cloth. On the lower run this belt is supported on its own rollers, and is driven in the same way and at the same speed as the conveyer 1. The finer mesh of the textile belt prevents the passage of fibres through the main conveyer, and enables thin sheets of material to be made. The textile belt may be applied to or removed from the machine when desired.

[Class 80 (ii).] In gearing of the kind comprising epicyclic trains, which are braked to give the various ratios, in combination with a hydraulic coupling the top gear drive is obtained by clutching the sun pinion or the annulus of the last group of gears direct to the primary member of the hydraulic coupling. The sun pinion 11 is connected to the disc 9 which is connected by sliding dogs 6, 7, to a sleeve 3 which carries the inner cone member 13, 14, which engages the outer cone 15 on the primary member 16 of the hydraulic coupling. A spring 17 normally holds the clutch out of engagement the operation of the clutch being effected by a spiral groove 23 on a collar 22, longitudinal movement of the cone 14 being obtained on rotating this collar. The top gear drive is thus obtained partly from the primary member of the coupling through the gear trains and partly from the runner 2 of the coupling through the sun gears 1 which reduces the top gear slip. In the Fig. shown, brakes on the drums A, B and C provide three gears in addition to the top gear. When only two other gears C and B are provided the annulus B is clutched to the primary member of the coupling to give the top gear.
