Title: Upper tool support for a stamping machine or the like
Inventor: SCHULTE KARL-HEINZ
IPC: B21D37/04
Filed: 1987-11-03
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE           An upper tool support (4) for a stamping machine or the like has at least one or several stamping tools (5) adjacently located.  Each stamping tool (5)  has a punch (7), a punch support (8) and a retaining nut (9) connecting the punch (7) with the punch support (8).  The upper tool support (4) is provided with a support body (10), and a receiving plate (11) with a tool guide (12) for each stamping tool (5) extending in the direction of stamping.  The upper end of the stamping tool (5) is limited to move in the stamping direction by support flanges (15), being thus guided in the direction of stamping.  A receptacle (17) for the upper end of each stamping tool (5) is provided in the support body (10), above the tool guide (12) and below a power transfer area (16).  The receptacle (17) is bridged by means of a power transfer rod (18) which is generally movable in a direction perpendicular to the stamping direction.  A lifting lever (20) is provided on the support body (10) associated with each stamping tool (5).  Each lifting lever 20 laterally surrounds from below the upper end of the associated stamping tool (5).  The upper end of the stamping tool (5) is actively liftable into the receptacle (17) by means of the lifting lever (20) when the power transfer rod (18) is pulled back.  In this upper tool support (4), jamming of the stamping tool (5) and the power transfer rod (18) are systematically avoided because the upper end of the stamping tool (5) can be actively lowered out of the receptacle (17) by means of the lifting lever (20) when the power transfer rod is moved forward, namely in the direction toward the receptacle (17).  A collision between the upper end of the stamping tool (5) and the power transfer rod (18) is thus made impossible by the forced control.

Title: Fluid flow control valve
Inventor: EIDSMORE PAUL G
IPC: F16K17/24
Filed: 1987-11-23
Granted: 1990-11-20
Abstract: Abstract of the Disclosure A flow limit valve for limiting the flow rate of a pressurized fluid includes a valve body with an interconnecting cavity of circular cross section. Within the cavity is a piston that slides within the cavity under force generated by a pressure differential across the piston to a closed position in engagement with a seat at the end of the cavity.  A first encapsulated magnet is carried within the valve body in a chamber located on the side of the seat opposite the cavity.  The first encapsulated magnet can be moved in response to another magnet outside the valve body to move a pin which can extend through the seat when the piston is in a closed position to thereby move the piston to an open position.  The magnetic forces applied through the valve body affect internal valve operation via the pin and thus avoids the danger of noxious fluids escaping through sliding seals or flexible membranes.

Title: Process and automatic packaging machine for letter envelopes and mailing wallets
Inventor: NOLTE BERT
IPC: B65H33/02
Filed: 1987-12-08
Granted: 1992-02-18
Abstract: Abstract Process and automatic packaging machine for letter en-velopes and mailing wallets In the process for packaging letter envelopes and mailing wallets, the packaging batch is counted in the end region of the production machine, and the individual article of the packaging batch corresponding to the spe-cific batch size is pushed a certain distance sideways out of the path of movement of the packaging batch in one direction or the other as a counting article.  The packaging batch is deposited on a conveyor belt and conveyed away.  A stack support keeps the stack approxi-mately vertical on its end face.  The stack support is advanced in front of the stack at the conveying speed of the conveyor belt.  As soon as the counting article at the end of a stack has arrived at a transfer point which is at a relatively long distance from the pro-duction machine, a separating device is introduced in-to the stack, with the result that the following por-tion of the packaging batch is temporarily halted.  Dur-ing this time, the separated stack is pushed, at the same height, into an open container via a slide track.          Subsequently, the stack support is guided back to the separation point, and the separating device is retracted from the end face of the following packaging batch, after which the stack support once again takes over the vertical guidance of the packaging batch, until the next counting article has arrived at the separation point.          The automatic packaging machine for letter envelopes and mailing wallets has several devices, by means of which the individual steps of the process are executed partly alone and partly in combination with one another.            The proposed drawing is Figure 1.
