Abstract: 1282881 Torsional vibration dampers POWDER COUPLINGS Ltd 22 Jan 1970 [24 Jan 1969] 4233/69 Heading F2S An inertial torsional vibration damper with damping which varies according to the speed of rotation of the inertia mass is of the type comprising a rotor 1, 3 for attachment to a shaft 2 subject to torsional vibration, a drum 6 providing an inertia mass supported for rotation relative to the rotor and containing a vibration damping medium (e.g. shot) 9 which, when the drum is rotated, is acted upon by centrifugal force and forms a layer spaced from the rotor, and a member 8 mounted for rotation with the rotor and extending radially outwards into the layer of vibration damping medium during rotation of the drum. The invention provides a layer 12 of resilient material lining the inside wall of the drum. As the rotational speed of the drum increases, the centrifugal force of the layer of vibration damping medium against the resilient lining 12 also increases and the lining yields, thus reducing the depth of immersion of the member 8 in the medium 9 and therefore the damping.

Title: Improved method of manufacturing viscose rayon
IPC: D03D27/00
Filed: 1946-02-12
Abstract: Viscose rayon suitable for making pile fabrics is made by a process comprising the following combination of steps taken during the preparation and the spinning of the viscose: (1) precooling of the viscose to a temperature below 15 DEG  C.; (2) filtration of the viscose in the presence of finely dispersed filter-aid substances such as diatomite; (3) using caustic soda lye containing not more than 0.8 per cent of hemi-cellulose in the preparation of the viscose.  Preferably, the filtered viscose is conveyed in pipes made of inert metal such as stainless steel, nickel, or nickel alloys. Gear-wheel pumps may be used for supplying the viscose to the spinnerets.  The spinnerets should be kept clean and they should be free from scratches.  Clogging may be reduced by carrying out the spinning in presence of cation-active substances or other substances having a similar effect.  The spinning is preferably carried out with horizontal travel of the filaments in the coagulation bath so as to reduce the length of travel of the cooled viscose in the supply pipe which is immersed in the coagulation bath.  The viscose may be cooled by surrounding the swan-neck or the filter candle with a cooling bath, but it is preferable to carry it out on the mass of the viscose, e.g. by means of an apparatus comprising thin plates between which the viscose circulates in thin layers. Specification 469,817 is referred to.
