Patent DE-3205186-A1 (DE)
Title: Method for producing a silencing filling for an exhaust silencer
Inventor: SEITZ WILFRIED
IPC: F01N13/18
Filed: 1982-02-13
Abstract: The invention relates to a method for producing a silencing filling for an internal-combustion engine exhaust silencer using mineral wool whose shape is at least partially stabilised by means of a synthetic resin binder. Such fillings were until now generally produced in the form of two main shells which were pushed into the exhaust silencer on both sides of the exhaust pipe and whose manufacture included mechanical treatment from boards, with a considerable labour cost and material losses. According to the invention, the exhaust silencer filling is produced as an integral moulded body in that layers of mineral wool fleece (9) are laid around a core (7) which corresponds to the exhaust pipe, which layers are at least partially impregnated with a synthetic resin binder, the entirety is surrounded by a circumferential moulding (15) and is thermally cured, and the complete moulded body is then removed from the mould. The exhaust silencer filling produced in this way can also be fitted in the exhaust silencer without problems by being pushed in from the side. <IMAGE>

Title: Locking device on a safe-deposit box lock
IPC: E05B35/12
Filed: 1982-07-08
Abstract: The invention relates to a locking device on a safe-deposit box lock, having a locking unit actuable by means of a customer key and with a push bolt and tumblers, the push bolt working at the same time as a control bolt and having an advance rod with a spring-loaded driving tooth which, when the push bolt is in the locking position, engages into a spring-loaded pinion which can be pressed forwards and backwards. The pinion can be pressed backwards out of its blocking position for the inclined customer key, so that the customer key can be rotated further and withdrawn and exchanged for a new customer key. With the toothed discs released, in the course of the return of the push bolt into the locking position by forward rotation, the new customer key aligns the tumblers with its stepped portions, so that, after the toothed discs have been clamped together, the tumblers are fixed, by means of end toothed segments meshing with the toothed discs, in an operating position aligned with the new customer key. <IMAGE>
Patent DE-3227152-A1 (DE)
Title: Transformer-type power section with mains isolation for television sets
Inventor: ROSENTHAL HANS-DIETRICH
IPC: H04N3/185
Filed: 1982-07-21
Abstract: A transformer-type power section is presented in which free oscillations occur during the start-up phase on the mains-connected side and which is operated with the horizontal deflection frequency from the mains-isolated side in steady-state operation. During the start-up phase, voltages occur on the mains-isolated side which are still below the rated voltages but which are sufficient, nevertheless, for allowing at least the horizontal deflection section and the voltage regulating circuit located on the mains-isolated side to start up. The voltage regulating circuit generates a pulse duration modulated signal which is transferred to the mains-connected side and is so used for driving the switching transistor. Inspite of mains isolation, the power section does not need a transformer operated at mains frequency, but operates with the horizontal deflection frequency and does not regulate a reference voltage but the actual voltage to be kept constant. <IMAGE>

Patent DE-3334851-A1 (DE)
Title: Method and device for the rapid charging of nickel-cadmium batteries
Inventor: ERAT AUGUST DIPL ING
IPC: G01R31/36
Filed: 1983-09-27
Abstract: A method and a device are proposed which are used for the rapid charging of nickel-cadmium batteries. The method is based on an electronic circuit by means of which the gradient of the charge characteristic which rises until the battery is fully charged is measured and evaluated. In detail, the battery voltage (UB) at specific times (tZ1...) is converted by means of a DC voltage/frequency converter (13) into a pulsed voltage (Up) at a frequency (fp) which is proportional to the respective measurement. An electronic counter (15) counts the pulses of the pulsed voltage for a first measurement time (T1) in the forwards direction, and subsequently for a second measurement time (T2) of equal length, in the rearwards direction. If the difference between the counter result in the forwards direction and the counter result in the rearwards direction is equal to zero or positive, then the battery is fully charged and the rapid charging current (IS) is automatically cut off. The cut-off may also be carried out even shortly before the time when the battery is fully charged, by presetting the electronic counter. In the state when it is cut off from the rapid charging current, a continuous charging current (ID), which does not overload the battery, may be supplied to the battery, if required. <IMAGE>

Title: Process and apparatus for covering weld seams on sheet metal casks and the like
Inventor: ROSEWICZ HORST DR
IPC: B05D3/12
Filed: 1983-12-23
Abstract: The sheet metal casks and the like are made of coated steel sheets. After the deformation of the sheets and welding of the edge zones, free from coating, of the steel sheets to a cask body, the uncoated zone of the cask body is uniformly heated to a temperature of 230-350 DEG C and is lined internally and/or externally with a plasticised plastic. To obtain good adhesion to the substrate:     -low-stress active material is used -the sheet metal of the weld seam zones is brought to comparable temperatures before the coating, and -after the molten band has been applied it is acted on with pressure.     The uniform course of the temperature over the whole length of the weld zone (tempering), and also the use of low-stress plastics, largely prevents the occurrence of stresses leading to peeling.
