Patent EP-0297434-A1 (EP)
Inventor: FEUSTEL HELMUT DR DIPL-ING
IPC: B31B50/02
Filed: 1988-06-23
Abstract: The device serves for controlling machines (1) for the production of bags or sacks which are welded from thermoplastic tubular or half-tubular webs. It possesses a pair of feed rollers (3) for the web, which is driven directly by a motor (4) or by a motor (4) via a gear (5, 6), a pair of welding jaws (7) which provide the web with weld seams, transverse weld seams or transverse-weld separating seams and whose movements are derived from a second motor (8) via a gear (9), and, if appropriate, further processing means which are provided with drives, such as punches, perforating cutters, depositing stations or the like. So that the output of such a device can be further increased in spite of separate drives for the feed rollers (3) and welding jaws (7), there is provided a central arithmetic unit (10) which controls the motors (4, 8) in such a way that drive energy is already supplied to the motor (8) of the pair of welding jaws (7) while the motor (4) which drives the pair of feed rollers (3) is still receiving drive energy for driving the pair of feed rollers (3). After the stop phase of the motor (4) of the pair of feed rollers (3), the said motor (4) is already driven before the motor (8) of the pair of welding jaws (7) has come to a stop.

Abstract: An apparatus for measuring the temperature lapse rate of the environment surrounding an aircraft in flight is described. The measured temperature lapse rate is compared with the dry adiabatic temperature lapse rate. If the measured temperature lapse rate is less than the dry adiabatic temperature lapse rate, a cautionary message is issued to the flight crew alerting them of the probability of microburst windshears. In addition, if the cautionary message has been issued and a rapid reversal of the measured temperature lapse rate occurs, a warning message is issued to the flight crew advising them of the probable penetration of a microburst windshear.

Filed: 1987-12-17
Abstract: Conventional apparatus for pressing the track 
links onto pin and bushings of the track chain during 
assembly thereof experience difficulty in aligning the 
links with the pin and bushings because the presses be­
come somewhat loose and out of alignment. The subject 
apparatus overcomes this problem by providing a self 
aligning feature in the link locating and driving means 
(24, 26). The link locating and driving means (24, 26) is 
mounted on the pressure plate (70) that is attached to 
the press rams (20, 22). A support plate (62) is guided 
from the pressure plate (70) by guides (64) and resilient 
means (68) that allow the support plate (62) to shift with 
respect to the pressure plate (70) with the aid of tapered 
noses (80, 82) on plungers (54, 56) supported by pres­
sure barrels (28, 30) as the rams (20, 22) move forwardly 
to press the links (51, 52) onto the pin (50) and bushings 
(48) held in a fixture. In this manner any misalignment 
is accounted for by the self-aligning feature of the locat­
ing and driving means.

Abstract: An electric punch includes a main body frame (1) having two punching holes (35,35) leading to a waste storage chamber (4) below. A pair of guide bores (34,34) support a pair of punching blocks (36,36) aligned with, and movable into, the respective punching holes (35,35). Two operation arms (40,40) are pivoted on respective holders. Each operation arm (40,40) is connected to one punching block (36) to impart vertical motion thereto. Each operation arm (40,40) includes a longitudinal guide groove (43) therein. A pair of operation pins (30,30) are driven in circular paths within the guide grooves (43,43) to reciprocate the operation arms (40,40) about their pivots. In the quiescent condition, the one of the guide pins (30,30) lies at the end of its guide groove (43), whereas the other guide pin (30) lies about in the middle of its guide groove (43). A guide concavity (44) at the end of the guide grooves (43,43) accepts its respective operation pin (30), whereby the associated operation arm   (40) rests at a different rotational position than it would if the guide concavity (44) were omitted. A spring (45) provides a restoring force on the punching block (36,36) associated with the guide concavity (44). The guide grooves (43,43) and holders may be positioned at selectable spacings. A reversing switch (57) permits reversing the direction of the circular paths to clear jams.
