Mouldable flocked material comprises a layer of stretchable fabric 3 which has been bonded to a layer of thermoplastic material 1 whilst the latter was in a liquid or tacky state, the fabric 3 or the material 1 having flock 5 adhered thereto. In one method of making the flocked material, release material 2 has a layer of p.v.c. applied thereto by passing it beneath a curtain 1a of p.v.c. in the liquid state. Whilst the p.v.c. is still liquid or tacky a stretchable fabric 3 is applied thereto at the nip of pressure rollers 6 and the laminate so formed is dried beneath a drier 7, after which the material 2 is removed. A coating 4 of thermoplastic or thermosetting paste or adhesive is then applied to the p.v.c. layer or, as shown, to the fabric 3, and flock 5 is applied to the coating 4 e.g. by electro-deposition. The flexible flocked material so formed is cured or fused. The flocked material may be subsequently formed, e.g. by vacuum-forming, and may be used in upholstery or as a vehicle floor covering.

Abstract: 1469429 Mixing GUNTHER PAPENMEIER KG MASCHINENUND APPARATEBAU 24 Dec 1974 [28 Dec 1973] 55695/ 74 Heading B1C Material is mixed by rotating a container containing the material, about an axis, and causing the material to move back and forth within the container in two opposite directions with the overall speed in one direction being greater than that in the other, adjustment of the speed rotation independently of the overall speeds of movement in the two opposite directions permitting independent adjustment of the amount of mixing and the flow rate. In one embodiment a container Fig. 2 is supported horizontally on rollers 3 which rotate the container relatively to its end walls 6 in which are rotatably mounted two parallel screw conveyors 4, 4 driven by motors 5, 5. The screw conveyors have different pitches. In use material is fed into an opening 9 and is carried with the rotating container to fall as a curtain over the screw conveyors, the conveyor 11 tending to move the material towards the outlet 10 and the conveyor 12 tending to move the material towards the inlet 9. The speeds of revolution or the pitches of the screw conveyors are chosen so that the movement in the direction of the outlet is the greater. In a modification two sets of adjustable blades 13, Fig. 4 are provided the blades of one set being set at an angle different from that of the other so that material on the wall of the container is forced towards the outlet 10. The containers may be cylindrical or conical and may rotate about a vertical or oblique axis and more than two screw or blade conveyors may be employed.

The coil and magnet assembly 40, 42, 44 of an electromagnetically controlled clutch is non- rotatably supported by an annular sheet-metal member 46 having some flexibility in the axial direction of the clutch. A hub section 50 of the member 46 has an annular ridge 52 which engages a housing wall 62, the hub section also being provided with three spring fingers 54 which bear against the inner race 18 of a bearing 14 for a torque transmitting member 10. A tab 56 of the member 46 extends axially beyond the ridge 52 to restrain the member 46 against rotation and to provide a guide for wire 58 to the coil 40. Flexibility of the member 46 permits slight deflection of the member against the wall 62 when the race 18 has been located by a snapring 66 which also provides easy removal of the clutch for service. An input drive consists of a V-belt member 20, 22 secured to the torque member 10 which, together with a second torque member 12, includes flux-conducting material. Spring members 24 attached to the torque member 12 provide disengagement spring bias and are attached, by a rubber ring 30, to a drive spider 32.
