Abstract: A sewing machine with adjustable upper and lower feed dogs is for sewing together sections of clothing in which ungathered segments of seams alternate with seam segments with differing degrees of gather. The spring-held presser foot is coordinated with a pneumatic cylinder as an additional mechanism of increasing contact pressure during the sewing of ungathered segments of seams. The cylinder is operable by a control cam connected to an adjusting mechanism for a stitch guide of one of the feed dogs. When sewing gathered segments, the pressure of the presser foot is greatly reduced, whereas the pressure is increased during the sewing of gathered seam segments and through a "fastening" step at the end of the seam.

In order to ensure the unwinding of the yarns with no crossing thereof, said yarns are unwound from bobbins of yarn which are co-axially disposed in a row, holes or other equivalent thread guiding means being provided, which guiding means rotate preferably with a continuous motion.

Abstract: A multipurpose puncher includes a pair of opposed stationary punch units positioned separately on a base, and a movable punch unit mounted slidably between the stationary punch units on the base. A press lever assembly is arranged so that it always associates with the movable punch unit and one of the stationary punch units to form a two-hole puncher while the other of the stationary punch units can be used as a single hole puncher. Furthermore, as desired, the press lever assembly can be adjusted to associate with all of the three punch units to form a three-hole puncher. When the two-hole puncher is formed, the distance between the axes of the punch members can be adjusted to be 78.5 mm. In addition, when the three-hole puncher is formed, the distance between any two adjacent punch members is preferably 108.5 mm.

Abstract: A process for calibrating a gas metering instrument comprises flushing a test chamber with a flushing gas and subsequently filling it with a calibrating gas having a predetermined composition of carrier substance and carrier gas. The calibrating gas does not have to be carried and made available constantly in its predetermined composition. Thereby a reduction in the volume of the gas metering instrument is obtained. For this purpose, provisions are made so that a feed device introduces a specified amount of calibrating substance from a reservoir into the heat chamber, whereupon the calibrating substance mixes with the flushing gas in the test chamber to form the calibrating gas of predetermined composition. In addition, equipment is described for implementing the process of calibrating a gas metering instrument.

Abstract: A secondary suspension for a rail vehicle truck is arranged between a suspension support connected to the car body of the vehicle and a spring support. It comprises several spring groups, whose spring elements each have a set of coil springs held by an upper and a lower spring plate and a metal-rubber spring element and are individually interchangeable. The spring elements are designed so that replacement of the spring groups can be carried out with the truck installed on the vehicle and without using a pressure stand or a lift. This goal is achieved by the fact that there are at least two diametrically opposed holder claws for spring tension holders on the upper and the lower spring plate of the spring groups, to which the spring tension holders are attached when the spring elements are compressed.

Abstract: A device for transferring bobbins of yarn from a bobbin container to a bobbin receptacle on a spooling frame where the yarn is "refined" by cutting out bad spots, has slide gate units (13, 14) that are divided into slide gate unit halves. On the basis of a control system that comprises in particular an optical monitoring device (40, 41, and 42, 43), a given row of bobbins are transferred by a box slide from the bobbin container to the slide gate units (13, 14) or sliding gate unit halves. In two steps they fall from there onto a pair of cross-conveyors (11, 12) that operate in opposite directions. Each cross-conveyor is associated with a righting chute (10). A bobbin that is on the outside by-passes the cross-conveyor and falls directly onto the righting chute, while the others are transferred, at intervals, to the righting chute, as it is emptied.
