Title: Punching tool with a plurality of punches for the simultaneous piercing of workpieces in the form of boards
Inventor: RICHTER DIETER ING GRAD
IPC: B26F1/14
Filed: 1981-03-14
Abstract: In a punching tool with a plurality of punches for the simultaneous piercing of workpieces in the form of boards, the individual punches are mounted displaceably in a punch-holding plate and engage in sliding fashion in those through-holes of a punching template arranged above them in which no index pins have been inserted. When the head part of the tool descends, the punches are pressed onto the board to be pierced by a plate which presses on the index pins, piercing being effected by interaction with a die plate. The punches displaceable in the punching template are, in contrast, pushed into the free punching space. Punching out of the corresponding holes is not possible. In order to allow rapid changing of the index pin configuration of the punching template, both the punching template and the punching pressure plate arranged above it are mounted in a manner which allows them to be pushed in in a guide slot in the head part of the tool. The pressure plate is somewhat thicker than the punching template, allowing the punching template to be lifted off from the pushed-in punches and removed after the pressure plate has been pulled out.

Title: Control device for the exhaust gas recirculation in an internal combustion engine
Inventor: HARUYA SHIRASE
IPC: F02M25/07
Filed: 1981-03-17
Abstract: An exhaust gas recirculation device has two modulating valves, one of which responds to the venturi vacuum and the exhaust gas recirculation pressure (prevailing immediately upstream of the exhaust gas recirculation flow control valve) and the other to the venturi vacuum and the intake vacuum. The first valve mainly reduces the vacuum, intended for operation of the exhaust gas recirculation flow control valve, when the internal combustion engine is working at high load, whilst the second valve reduces the vacuum mainly when the internal combustion engine is working at low load and/or high speed. By means of this combined operating principle, excessively large amounts of recirculated exhaust gas are avoided when the internal combustion engine is operating either at low load or high speed. <IMAGE>

Title: Inductive transmitter arrangement
Inventor: MEZGER MANFRED
IPC: F02P5/145
Filed: 1981-04-15
Abstract: An inductive transmitter (sensor) arrangement (10) having a rotating ferromagnetic part (12 to 16 and 22) is proposed which produces signals periodically in a pick-up winding (11), which signals are amplified in a downstream amplifier (18) and are supplied to a threshold stage (19) which is preferably configured as a Schmitt trigger. An essentially constant ratio between the signal amplitude produced and the threshold is set, at various rotation speeds, by varying the transmitter voltage production, the gain factor of the amplifier (18), or the switching thresholds of the threshold stage (19). Furthermore, a very low intrinsic variation is produced, as well as a signal-to-noise ratio which increases with increasing rotation speed and the reliability of low starting rotation speeds. <IMAGE>

Title: Speed governor for fuel injection pumps
Inventor: FIEDLER EBERHARD
IPC: F02M41/12
Filed: 1981-05-27
Abstract: A speed governor for fuel injection pumps has a pump piston (13) supported in the housing (11) and an annular slide valve (20), displaceable on this, which is pivoted on a speed signal sensor. A spherical head (20) of the speed signal sensor and a recess (26) of the annular slide valve (20) form an articulated coupling, the freedom from play of which is due to a two-armed leaf spring (31), which is clamped between the inner wall (35) of the housing (11) and an end face (36) of the annular slide valve (20). In this way, the disturbing influence on the governor is lessened and consequently the governor oscillations and the delivery quantity dispersions are reduced. <IMAGE>

Title: Empennage for a KE practice round
Inventor: BIELE JOACHIM K DR
IPC: F42B10/48
Filed: 1981-06-05
Abstract: In order drastically to shorten the range of rounds during practice firing on a predetermined flight path (trajectory) while maintaining the ballistic properties, a rod (bar) round (projectile) is provided with an empennage which consists of tubes (2) which are distributed uniformly on the circumference of the round body (1). The internal diameter of the tubes (2) is tapered symmetrically and conically from the air inlet opening as far as a narrowest cross-section which is located a short distance behind the air inlet opening. Behind that point, the cross-section remains constant. This design measure represents a Laval nozzle with a reverse flow which causes aerodynamic blocking above a specific Mach number during flight of the round, which blocking greatly increases the drag (air resistance) and thus rapidly reduces the speed of the round. <IMAGE>
