Patent DE-3326275-A1 (DE)
Title: Hydraulic single-tube shock absorber having a variable damping level
Inventor: SAPUNAROW-RYFFEL ANNA DOROTHEA
IPC: F16F9/346
Filed: 1983-07-21
Abstract: In order to control the damping of vehicle shock absorbers during operation, the cross-section of the hydraulic-oil flow holes is varied automatically, in a purely mechanical way, as a function of the road condition, the type of driving and the load. The damping control takes place by means of a forced rotation movement of at least one of a plurality of pistons which are fitted in a freely-rotating manner on the piston rod, in that the pistons are axially guided by means of depressions and/or projections on the housing inner wall so that the change in the damping level is dependent only on the selected geometric course of the piston guides. From a range of damping level variations which can be implemented, shock absorbers according to the invention can thus be produced which contribute to a considerable increase in the driving comfort and the safety of road vehicles.
Patent DE-3326464-A1 (DE)
Title: Telescopic sight
Inventor: PACINER RUDOLF
IPC: F41G1/38
Filed: 1983-07-22
Abstract: A telescopic sight (3a) has on the lens side a recess (8) which is matched to the outline shape of the rifle barrel in this region. As a result, the telescopic sight (3a) having its sighting line (V) can be mounted substantially closer to the core axis of the barrel. Swing errors have a substantially smaller effect due to this slight distance. In order to be able in a telescopic sight having adjustable magnification advantageously to make use for the aiming process of the high light intensity which is present at low magnification and exceeds that of the human eye, the telescopic sight (3a) has a stopping-down device (13) operating, for example, by means of an iris stop (15). As a result, the excess light intensity can be used to increase the depth of field. A further control device (16) having a tube (17) inside the telescopic sight (3a) is provided in order to avoid parallax errors. The entrance rim (18) and the exit rim (19) form control outlines in this case, which produce concentric rings for the marksman given a round tube (17) and the absence of parallax.   <IMAGE>

Title: Method for producing an electrical connection between a heating conductor provided with a sheath, and a sheathed PTC thermistor
Inventor: THIEDE HORST
IPC: H05B3/48
Filed: 1983-08-09
Abstract: A mineral-insulated heating conductor (1), which is surrounded by a metal sheath (2), is electrically connected with the aid of an insulating body (4) to a PTC thermistor (5), which is likewise surrounded by a sheath (10). Once the ends of the conductor wires (1, 5) are freed of the insulating material (3), which is in the form of powder, they are inserted in opposite directions into a continuous hole (6) in the insulating body (4) and are soldered or welded to one another there. Subsequently, the sheath ends are also connected in a gas-tight manner by soldering or welding. In this case, a locally tightly bounded transition region from the heating conductor to the PTC thermistor is produced. As a result of the use of the insulating body (4), refilling of the insulating material (3), which is in the form of powder, at the connecting point is superfluous. <IMAGE>

Title: Device for segregating metal parts
Inventor: KIND GUNTRAM
IPC: G01V3/11
Filed: 1983-11-26
Abstract: The invention relates to a device for segregating metal parts from a moving stream of conveyed material, for example ground or granular material, with the assistance of a metal detector and an actuating mechanism, controlled by the metal detector, for a segregating element which can be transferred into two final positions, in one of which it releases a conveying piece and in the other of which it closes and simultaneously opens an ejection piece through which the metal part falls out. In order to ensure that a minimum amount of acceptable material is segregated together with the metal particles, it is proposed to mount a further metal detector on the ejection piece, by means of which detector the operating mechanism is actuated and the segregating element is reset when a metal particle which has activated the first metal detector enters the reaction zone of the second metal detector, i.e. has been segregated. <IMAGE>

Patent DE-3409674-A1 (DE)
Title: Process for the production of ribbed nonferrous metal tubes
Inventor: GRAFFA JUERGEN
IPC: B21C37/26
Filed: 1984-03-16
Abstract: In the production of ribbed nonferrous metal tubes, the undeformed ribbed strip has hitherto first of all been passed with a longitudinal edge through a bath of flux and then through a tinning bath. After coating, the ribbed strip is deformed into a coil by rolling and, at the same time, wound directly onto the core tube. The soldering tin is then melted by hot air or by a naked flame, with the result that it also comes to rest on the core tube and, after it has cooled down, connects the core tube and the rib coil to one another. According to the invention, the circumferential surface of the unribbed core tube is first of all wetted with a flux and then coated with soldering tin. The untreated flat strip is then wound helically onto the core tube. The ribbed tube is thereupon passed through an induction coil and the soldering tin is thereby melted. The advantage of this method is less tool wear in coiling and a higher winding speed since the required soldering temperature can be applied more rapidly to the soldering location.
