Abstract: A double-cylinder shock absorber, which is particularly suitable for use in a MacPherson strut, includes an inner cylinder having a closed lower end and which is filled with oil. A piston rod extends into the inner cylinder through the upper end thereof. A piston is secured to the lower end of the piston rod and divides the cylinder into upper and lower oil chambers. The piston is provided with a fluid metering device providing a damping force mechanism. A rod guide head closes the upper end of the inner cylinder and is provided with an opening which is slightly spaced from the piston rod to form an annular clearance therebetween. An outer cylinder is coaxially disposed around the inner cylinder and forms therewith an annular reservoir chamber having closed upper and lower ends. The lower portion of the reservoir chamber is filled with oil and the upper portion is filled with gas.

Abstract: An improvement in a collating machine for stacking sheets of paper being fed seriatim thereto from a singulating feeder in the same order as the sheets appear in the singulating feeder. The collating machine includes a belt for transporting the sheets of paper, a ramp for lifting a succeeding sheet of paper over and onto a preceding, stopped sheet of paper, and a stopping device for stopping each sheet of paper after the sheet has been lifted by the ramp. The improvement includes a removable stacking device for stacking the sheets of paper in the reverse order as the sheets appear in the singulating feeder.
