Patent ES-280671-A1 (ES)
Title: Automatic regulating devices for hydraulic barrel-type pumps or motors
IPC: F04B1/20
Filed: 1962-09-10
Abstract: A rotating cylinder block swash plate pump or motor has a passage 19 interconnecting orifices 20, 21 formed in the valve plate 10 between the inlet port 8 and the delivery port 9.

Title: Separation of ferro-magnetic particles from non-magnetic particles
IPC: B03C1/22
Filed: 1967-04-25
Abstract: Ferro-magnetic particles are separated from non-magnetic particles in a mixture of finegrained materials by causing the mixture to flow as a gas-fluidised stream beneath an endless belt-type magnetic separator. In Fig. 1, the mixture of materials is fed via a chute 1 on to a gas-permeable bottom of a fluidised-bed conveyor which is closed at the top partly by a cover 7 and partly by an endless belt 8 within which is mounted a magnet 9. Fluidising air is introduced through a pipe 3 leading to distribution chambers 4, 5. Magnetic particles carried by the belt are released from magnetic attraction when the part of the belt comes over a chute 10 down which the magnetic particles fall. The non-magnetic particles are discharged through a chute 6. Transverse ribs 12 are provided on the belt to cause the magnetic particles to be carried by the belt beyond the edge 11 of the magnet 9. In another embodiment Fig. 2 (not shown) the chute (1') has a gas-permeable, steeply sloping bottom (2') and baffle plates (16, 17, 18) are provided to cause the material itself to form a gas seal at the entrance to the fluidised-bed conveyor. The bulk of the material passes over baffle (17) and heavy particles pass through the narrow clearance (21) which may be adjusted by adjusting the plate (17). The size of the entrance (19) for the material may be adjusted by adjusting the plate (16). The magnetic separator comprises a magnetic drum (9') over which a belt (8') passes. Magnetic particles are discharged through a chute (10') and non- magnetic particles through a chute (6'). Non- magnetic particles entrained with magnetic particles are removed from the belt by compressed air blown through a pipe (13). Dustladen gas is discharged via an outlet (14).

Title: Coiler assembly
IPC: B65H54/80
Filed: 1969-10-08
Abstract: Sliver is fed into a container 12 in a plurality of loops 32 (Fig. 2) by apparatus comprising a base 140, a calender roll assembly 14 for feeding the sliver, supported by the base, first drive means for rotating the calender roll assembly about an axis 20 offset from the container axis 28, second drive means for rotating the calender roll assembly about the axis 28, and means for adjusting the distance between these two axes. Rotation about central axis. A plate 36 bearing a ring gear 142 is driven by gear 136. Adjustment of inter-axial distance. The calender roll assembly 14 is rotatably mounted eccentrically in a circular plate 48 which is itself eccentrically carried by plate 36, and may be clamped thereto, after relative rotation to provide the desired inter-axial distance, by clamps 54. Rotation about offset axis. Gear 170 drives a ring gear 172 rotatably carried by plate 36, and fixed to an internal ring gear 204, which drives gear 200 (mounted in a slot in plate 36 to permit adjustment of the inter-axial distance), the gear 200 being engaged by a ring gear 206 carried by the calender roll assembly 14. Rotation of calender rolls. The calender rolls 86 are driven by a gear train 120, 118, 114, 108, 100 which is driven by the relative rotation between calender roll assembly 14 and the eccentric plate 48, gear 100 engaging an internal ring gear 104 fixed to the underside of plate 48. Speed variations. The overlap between adjacent sliver loops 32 may be adjusted by replacing a pair of gears 280 282 (Fig. 8, not shown) in the drive to gear 136 with a different pair, thus changing the rate of rotation of plate 36. Such a change produces a small change in sliver delivery speed by changing the speed of rolls 86. This may be compensated by replacing gears 108, 114 with a different pair.
