Title: Method of loading operating programs which are required for operation of electrical devices
Inventor: SCHUERMANN CORNELIUS DIPL ING
IPC: G06F9/4401
Filed: 1993-03-09
Abstract: Operating programs are loaded into a program-controlled electrical device (e.g. DUE1) using an external operating device (PC). In this, there is at least one load file, which contains a device identity, as well as the code sequence of the relevant operating program and information about the memory addresses at which the code sequence is to be stored in the relevant electrical device.

Patent DE-4311602-A1 (DE)
Inventor: SEIFFARTH STEFFEN DIPL ING
IPC: B42F9/00
Filed: 1993-04-08
Abstract: The invention relates to a clip binder for unpunched papers, having a binder spine (10), a back cover (14) moulded onto the binder spine (10) and a clip (40) capable of limited movement transversely to the binder spine (10) between a release position and a clipping position. The clip (40) has two resiliently splayable clip legs (42, 44), of which one, the rear clip leg (42), engages behind the back cover (14) and the other, front clip leg (44) can be pushed onto a retaining strip (24), which engages over the papers at the edge, with an obliquely backward projecting clip rib (46), with intermediate clipping of the papers. Provided on the retaining strip is a stop lip (28) projecting forwards from one fold edge (26), against which the clip rib (46) of the clip (40) stops in the release position. In order to guarantee reliable handling when papers are introduced into and removed from the binder, even when a relatively soft and deformable binder material is used, the projecting part of the stop lip (28) is welded to the retaining strip (24) on both sides outside the stop region of the clip rib (46), forming a laterally limited stop pocket (34). <IMAGE>

Title: Control system for catalyser in vehicle exhaust - monitors saturation of the gases through catalyser relative to changes in the fuel-air mixture
Inventor: YAMASHITA YUKIHIRO
IPC: F02D41/14
Filed: 1993-07-05
Abstract: The exhaust gases are monitored upstream and downstream of the catalyser to determine the effectiveness of the catalyser. The fuel-air mixture entering the engine and the make-up of the exhaust gases are monitored wrt time to determine if the make-up of the gases leaving the catalyser follows a programmed pattern, or if the unit is operating below a set standard e.g. it requires replacing. The processor control takes into account the adsorption of oxygen inside the catalyser wrt temperature and the saturation level of the exhaust gases. Programmed changes in the input fuel-air mixture are monitored through the exhaust system to provide a simple check of the effectiveness of the catalyser. ADVANTAGE - Simple self-analysis of exhaust treatment.
Patent DE-4326236-A1 (DE)
Title: Method of deburring or chamfering workpieces and device for carrying out this method
Inventor: MEINERS ECKHARD DIPL ING
IPC: B23K26/12
Filed: 1993-08-05
Abstract: To deburr or chamfer workpieces, a laser beam (16) is directed locally onto the area of the edge (7) of the workpiece (1) and if need be is guided along this edge (7). At the same time, a reaction medium is directed against the edge area of the workpiece (1). At the temperatures in the area of the edge (7) of the workpiece (1) which are produced by the laser beam (16), the reaction medium transforms the material to be removed there into an easily removable reaction product. The kinetic energy of the reaction medium is here kept so low that the transformation of the material of the workpiece (1) into the reaction product takes place "in situ" without the reaction medium itself being able to contribute to the evacuation of any molten material. On account of the thermodynamic conditions, in particular the heat-conduction conditions brought about by the geometry, a rounded edge form results, the configuration of which is determined not by the processing strategy of the laser beam (16) relative to the workpiece (1) but solely by the parameters of the method (Figure 3). <IMAGE>

Patent DE-4344399-A1 (DE)
Inventor: KOIDE TERUHIKO
IPC: B60R22/46
Filed: 1993-12-24
Abstract: The sensor has an ignition pin 24, an inertia mass body 32 and a trigger lever 38. The ignition pin, when released, is moved in an axial direction thereof by a firing spring 30 so as to ignite a detonator 56 in a gas generator 50 which operates the pretensioner. The trigger lever 38 normally holds the ignition pin 24 in the state shown in which the ignition pin is separated from the detonator 56. When, due to the deceleration, the inertial mass body is moved a predetermined distance or more in direction of arrow A against spring 36, the trigger lever releases the ignition pin. The present sensor reduces the negative influence received from fricitional force and ensures stable operation characteristics in a simple structure, and can be easily reset. <IMAGE>
