Patent DE-4318777-A1 (DE)
Title: Device for assisting sheet conveying
Inventor: KOCH MICHAEL DR
IPC: B41F21/10
Filed: 1993-06-05
Abstract: The invention relates to a device for assisting sheet conveying by means of jets of compressed air in the region of the printing zone of the blanket cylinder and the impression cylinder in a printing unit which is not involved in printing, a printing gap being present between the blanket cylinder and the impression cylinder of a multicolour sheet-fed rotary printing machine. The object of the invention, to build up an air cushion between the sheet and the blanket cylinder for a printing unit which is not involved in printing whilst maintaining a smooth sheet run, is achieved in that known axially parallel blower pipes extending over the width of the cylinders are arranged ahead of and behind the printing zone,   - the nozzles of the blower pipe ahead of the printing zone blowing a jet of compressed air against the blanket cylinder, - the nozzles of the blower pipe behind the printing zone blowing a jet of compressed air against the impression cylinder, - one nozzle of the blower pipe ahead of the printing zone being disposed in each case opposite a nozzle of the blower pipe behind the printing zone, and - in that the jets of compressed air contact the sheet and smooth it out counter to the direction of movement of the sheet.   <IMAGE>

Title: Control arrangement for air/fuel mixture supplied to IC engine - Has electronic control unit with correcting procedure for position of stepper motor used to operate throttle flap
Inventor: SUZUKI NORIO
IPC: F02B1/04
Filed: 1993-07-26
Abstract: A fuel feed control device for an IC engine can adjust either the amount of intake-air or the amount of fuel and has a stepper motor (15) to drive the adjuster, according to signals from an electronic unit (20). There is a sensor to detect the position of the throttle flap (4). One stage in the flow diagram, is the detection of any deviation of a stepper motor step from the value sent by the control unit, on the basis of throttle flap position. A correction is instigated in the form of a number of further motor steps. Another stage is the determination of the fully closed throttle flap position. ADVANTAGE- Possible errors in stepper motor position rapidly corrected.

Patent DE-4330531-A1 (DE)
Title: Device and method for damping the movement of the armature of electromagnets
Inventor: LOEFFLER HORST DIPL ING
IPC: H01F7/18
Filed: 1993-09-09
Abstract: The armature of an electromagnet experiences increasing acceleration during its movement from the non-energised quiescent position into the limit position when the coil is excited. This results in it knocking hard against the end stop, this being associated with noise being produced and with vibration. The invention comprises a method and a device with whose aid the coil current of the magnet is influenced in such a manner that, as the air gap reduces, the armature speed is reduced when the coil is energised in such a manner that the armature lands on the end stop at a low speed, and the development of noise and vibration in consequence are avoided. In order to achieve this, a signal is produced which is proportional to the armature speed. A functional dependence, which is contained in this signal, on the current is corrected by division by the coil current. If a current control loop keeps the result of the division constant, then the armature speed is reduced as the air gap becomes smaller. The invention can be used with electromagnets of any desired physical shape.

Title: Dirt trapper for a light water nuclear reactor fuel element - comprising one or more coiled springs in a filter arrangement below the bottom grid of the fuel element
Inventor: SOEDERLUND ANDERS
IPC: G21C3/32
Filed: 1993-09-25
Abstract: A fuel element for a light water nuclear reactor, comprises a large number of vertically aligned fuel rods (12) with bottom grid plate (13) and top grid plate (14). The grid plates are holed to permit coolant passage. The novelty comprises a dirt trapper or filter (18) arranged below the bottom grid plate (13). The dirt trapper (18) comprises at least one coiled spring arranged and held within a planar groove. The groove can be spiral or a number of concentric grooves can be used. One or more planar arrangements of grooves and springs can be used. USE/ADVANTAGE - The dirt trapper is to remove any unwanted coolant particles that might damage the fuel rod cladding and lead to an unwanted accident. The dirt trapper (18) efficiently removes unwanted particles in the coolant without causing too large a pressure drop in the coolant flow. It is of simple design and can be retrofitted to existing plant.

Title: Hydraulic solenoid valve
Inventor: MUSCHONG GUENTHER
IPC: F15B13/044
Filed: 1993-11-10
Abstract: The invention proposes a hydraulic solenoid valve having a sleeve-like armature (3) which can be displaced counter to the force of a spring (4) on a non-magnetisable control tube (10) upon excitation of a solenoid coil (1), is designed as a spool valve and extends over at least two radial through-passages (16, 21) which are connected to hydraulic channels (12, 13) running in the control tube. The control tube (10) is likewise axially displaceably mounted and is connected to a valve piston (6) of a valve. The first hydraulic channel (12) is acted upon by a control pressure, and the second hydraulic channel (13) is connected to a regulating surface (control chamber 14) of the valve piston (6), by means of which the valve piston (6) can be moved counter to a counter-pressure. Since the control tube follows the movement of the armature in a regulating movement, a regulated position of the valve piston (6) is always obtained in dependence on the position of the armature (3) without electrical readjustment being necessary. <IMAGE>

Title: Open car door annunciator-indicator
Inventor: NIEMANN HERMANN W
IPC: B60Q1/52
Filed: 1994-02-15
Abstract: The direction indicator lamps of a car can be used to warn that a door is open. Instead of the on-off (two-way) flashing, indicating a lane change or turn, or four-way flashing indicating danger, a steady illumination on one side indicates a door open on that side.

IPC: F16H7/12
Filed: 1994-07-25
Abstract: An autotensioner for use in applying a tension to a moving belt comprises a pivotally-mounted arm carrying a belt tensioning pulley, and a damper 19 acting on the arm, the damper 19 comprising a cylinder 24 for fluid divided into an upper chamber and a lower chamber by an upwardly spring-biased piston 25; a check valve 34 between the chambers which opens for flow from the upper to the lower chamber via a passage 33 in the piston; and a push member 22 acting on the piston from above. The lower part of push member 22 has a cavity 31 which is open to the passage 33 and communicates with the external part 35 of the upper chamber via vent holes 36. The damper 19 can follow a sudden change in tension of the belt so that the viscous fluid has a liquid surface kept high even when the push member 22 rises to its uppermost position to prevent air from entering underneath the piston 25. The pulley-carrying arm may also be biassed against the belt by a coil spring separate from the damper. The cavity 31 within the push member 22 may also extend into the upper part 27 of that member. <IMAGE>

Patent DE-4446464-A1 (DE)
Title: Spring driven door lock for cars
Inventor: EPARS PIERRE-ARNAUD
IPC: E05B65/32
Filed: 1994-12-28
Abstract: The lock has a latch (6) which rotates round an axis against a spring between a locked position where the latch holds the striking plate and an unlocked position where the striking plate is released from the latch. It has a knuckle joint with two arms (10, 11) hinged together. The end of one arm is hinged to the lock housing (10) and the end of the other is attached to the latch (6). The length of the arms and the position of the axes of articulation on the housing and the latch are designed so that as the lock moves from an unlocked to locked position the axis of rotation (12) of the 2 arms of the knuckle joint pass from one side to the other of the line (15).  When moving from the locked to the unlocked position the axis of rotation (14) of the knuckle joint passes from one side the other of the line (16) passing through the axis of articulation of the two arms of the knuckle joint and the axis of rotation of the latch. When being locked or unlocked the initial rotation presses against the spring (13) until it reaches an unstable position following an angle greater than the final angle of rotation of the latch. At this point the spring moves in the direction of the rotation.
