Title: A suction device for the pneumatic removal of waste from cards
IPC: D01G15/82
Filed: 1957-06-07
Abstract: 856,821. Removing waste from carding machines. LUWA A. G. June 7, 1957 [June 11, 1956], No. 18226/57. Class 120(3). In an arrangement for removing waste pneumatically from a carding machine in which the space below the cylinder and the licker-in is connected to a collecting conduit or conduits communicating with the intake side of a blower or blowers, this space is divided into at least one chamber for the licker-in and at least one for the cylinder; the two sets of chambers communicating with a blower through connections of which the cross-sections are such that different amounts of air are withdrawn from the licker-in and cylinder chambers in the same period. In this way, the suction applied to the licker-in can be greater than that applied to the cylinder to prevent good material being drawn off the latter. In a form with one chamber for each of the two parts, an area formed by plates 12, 17 and the ends of the machine is divided by a partition 13. The chambers so formed communicate with a duct 19 connected to the intake side of a blower, the other side of which has a filter and nozzles, 23, 25 serving to blow waste toward the duct. The latter are disposed below a strip 26 between the cylinder and the doffer. The amount of air withdrawn from the two chambers can be raised by adjusting the ends of the plate 12 and of the partition 13. A third chamber 27 may be provided below the doffer 5 with a duct 29 through which the amount of air withdrawn may be governed by an adjustable strip on the end of anend plate 11. The blower for this chamber may be separate from that used in connection with the other two, in which case it may operate intermittently. Alternatively, one blower may be used for all three chambers with a filter and gate. provided if desired the duct 29 and the blower. The chambers 14, 15 may be entirely separate with separate collecting conduits with or without a separate blower: in the latter case a filter is provided in the circuit. The blower for the nozzles may be separate from that providing the suction. In another form, Fig. 3 not shown, an air intake may be provided in front of the feed rollers, and a partition comprising two hinged members may be provided between the cylinder and doffer chambers. The bottom plates of the cylinder and licker-in chambers may be provided with vibrators, and the plate 17 may be composed of a number of members one above the other.

Abstract: 141,986. Whiteley, W., and Smith, F. July 28, 1919. Magnetos, driving.-Trip or accelerating-mechanism for driving the ignition magneto of an internal-combustion engine at starting comprises a disk 3 fastened to the driving-shaft 1 and a flanged disk 2 loosely mounted on the shaft and coupled by pins 4 to the magneto, the disks being connected together by a spring 9. Projections 8 on the periphery of the disk 3 fit into recesses 6 in the flange of the disk 2 so as to allow of a certain amount of lost motion between the disks. The disk 3 has a squared hub 16 which enters recesses in a pair of plates 11 provided with projections 12, 13 entering slots 14 in the flange of the disk 2. The projections 13 are longer than the projections 12, and during the " cranking " of the engine these projections engage an adjustable stop 17 until they are removed by the rotation of the squared part 16, causing the spring 9 to give a rapid movement to the disk 2. After the engine has started, the plates 11 are moved centrifugally and withdraw the projections from contact with the stop 17. In a modification, the plates 11 form the straps of eccentrics keyed upon the shaft 1. The stop 17, Fig. 9, in this case may be removed from the path of the rotating projections by means of a wire 27 actuated by means connected with the starting lever.

Abstract: 637,198. Microscopes. WATSON & SONS, Ltd., W., and REYERSBACH, C. D. July 14, 1947, No. 18735. [Class 97 (i)] In a microscope in which the eye-piece may be moved to vary the angle of its axis relative to that of the objective and a compensating member is rotated automatically to maintain the image in the eye-piece and in the correct attitude, the member is on an arm rotatable about an axis transverse to that of the objective, which arm also carries the eye-piece rotatable about an axis parallel to that of the arm, interengaging gears fixed to the objective and eye-piece, causing the axis of the latter to . move as the eye-piece is rotated, whereby the arm and also the compensating member are rotated. The invention is described as applied to a microscope having a rotatable nose-piece for objectives 8 and a housing 34 movable in an arcuate slot 33 and having a circular flange to support an eye-piece. A beam 7, incident on the objective is reflected at right angles as beam 16 by a prism 15 on to a prism 25, forming the compensating member, whence it is successively reflected by two perpendicular surfaces 27, 28 thereof to a prism 35 fixed to the housing 34 whence it reaches the eye-piece. The prism 25 is supported on a plate 23 supported on a pivot 17 so as to be rotatable about the axis of the beam 16, the plate 23 carrying at its other end a pivot 32 through which the reflected beam passes and which supports the housing 34. A gear 38, coaxial with the beam 16, is fixed to the casing, and a gear 37 meshing therewith, is fixed to the housing 34. Thus when the housing 34 is moved from the position shown in Fig. 4 to that in Fig. 5 to adjust the eye-piece, the prism 25 rotates about the axis 16, and the gears 37, 38 cause the housing 34 and hence the prism 35 to rotate through an equal angle relative to the prism 25, whereby the image is maintained correctly oriented and positioned in the eye-piece field. Lenses 14, 31 are provided to compensate the light path and allow standard objectives and eye-pieces to be used.

Abstract: 477,696. Regenerative furnaces. RAPPOLD, H., SAURBIER, H., and ZIMMERMANN & JANSEN GES. July 7, 1936, No. 18805. [Class 51 (i)] A reversing arrangement for regenerative furnaces comprises a gas valve a and a flue valve b interconnected so that one valve is closed before the other opens and the flue valve being positively closed by power driven means. In one form a motor u drives a double rack kl which in turn drives one of the pulleys z of an endless chain y. The operating rod i of the flue valve b is connected to the chain by a member y<1> so as to be positively closed -and opened thereby. The gas valve a is connected through a lost-motion coupling to a rope l secured to the upper end of the rack kl. This rack has teeth over only a part of the side which drives the pulley z so that the drive ceases when the valve b is closed although the rack continues to rise to lift the gas valve a. In a modified form, the motor u drives a single-sided rack connected by a rope l to the gas valve and having at its upper end a bellcrank lever working in guides by which it is caused to engage with and drive the endless chain y. In a further modification, the endless chain is directly driven by the motor u and the end of the rope l and the end of the rod i both carry hook members adapted to be engaged at the appropriate times by members carried by the chain.
