Title: Power supply unit for obtaining a stabilised output voltage
Inventor: LESCHE WOLFGANG DIPL ING
IPC: H02M7/155
Filed: 1986-07-14
Abstract: The invention relates to a power supply unit for obtaining a stabilised output voltage, having a transformer on the input side to whose secondary winding a bridge rectifier is connected. A charge capacitor is connected to the bridge rectifier via a controllable rectifier. The control input of the rectifier is connected to a phase-gating control device. In order to achieve a power supply unit which operates at high efficiency and with a low power loss, in one embodiment, the secondary winding (3) of the transformer (2) has a centre tap (4) which is connected to the charge capacitor (16) via a half-wave rectifier (37). In another embodiment of the power supply unit according to the invention, the controllable rectifier (40) is connected at that end of its switching path which faces away from the charge capacitor (16) via an auxiliary capacitor (42) to an AC voltage connection (43) of the bridge rectifier (7).

Title: Method for conveying printing products on rotary printing machines
Inventor: SCHUMANN FRANK
IPC: B41F13/54
Filed: 1986-07-28
Abstract: The invention relates to a method for the variable-speed conveyance of printing products on further-processing devices connected downstream of rotary printing machines. 
<??>With the method according to the invention, the printing products coming from the printing machine, in particular printed sheets, are slowed down by their receiving speed V1 being reduced by the circumferential speed V4 of the sunwheel cylinder, constructed as a processing cylinder, to achieve the processing speed directly when the product is gripped by the grippers of the planetary cylinders. The printed sheets are at least partially further processed, e.g. stapled, on the processing cylinder. The printed sheets are then accelerated again and transferred at the delivery speed V5 analogous to the receiving speed V1 to the further-processing assembly connected downstream of the planetary cylinder system. In this case, by maintaining the dimensioning and speed ratios intended in the method according to the invention, the same sheet-conveying elements are used both for receiving the printed sheets from the belt system connected downstream of the folding blade cylinder and for receiving them on a further-processing assembly, thus, in turn, ensuring precise sheet alignment and conveyance.

Patent DE-3711133-A1 (DE)
Title: Apparatus for arresting a cylindrical roller or the like
IPC: G03D3/13
Filed: 1987-04-02
Abstract: Apparatus for arresting a freely rotatable cylindrical roller fastened to a driveable shaft. In the case of rollers used in photographic developing machines, which have an eccentrically displaceable outer casing and are fastened rotatably with their hub on a driveable shaft, contamination can accumulate between the hub and the shaft and, in time, leads to the hub being driven by the shaft as a result of frictional engagement and to the roller rotating even when it should actually remain stationary. It has been attempted to prevent undesired rotation of this roller in the neutral central position with respect to the shaft by using a leaf spring which bears against the surface of the roller. By this means, the surface of the roller is damaged, and it is not ensured that the roller can really be arrested in the case of severe contamination. The novel apparatus is, however, intended to make it possible to prevent rotation of such rollers reliably, even when the contact surface between the hub and the shaft is quite severely contaminated. A holder, which does not rotate with the shaft, is arranged on the shaft and has a rigid coupling element which permanently projects into one of the two open ends of the roller. If the roller is in the resting position situated centrally with respect to the shaft, the cylindrical casing of the roller is in coupling engagement with the rigid coupling element arranged on the holder. If the cylindrical... Original abstract incomplete.

Title: Adjustable shock-absorbing leg for motor vehicles
Inventor: GRATZA PETER
IPC: B60G17/02
Filed: 1987-11-24
Abstract: An adjustable shock-absorbing leg (1) for motor vehicles is described whose adjustment requires little expenditure of force. For this purpose, a stop bushing (11) is located unloaded by a spring assembly of the adjustable shock absorbing leg (1) on a damper housing (2b). The spring assembly consists of two helical springs (6, 7) which are connected one behind the other and have a different spring constant and are separated by an annular element (8). Whilst in the case of low loading of the spring assembly the annular body (8) does not come to rest with the stop bushing (11) and therefore the softer, lower helical spring (7) leads to a low spring constant, in the event of the annular element (8) resting against the stop bushing (11), the harder upper helical spring (6) is actuated exclusively. By changing the distance between the annular element (8) and the stop bushing (11) a displacement-dependent and therefore load-dependent change in the spring constant can be achieved. The adjustment movement which is necessary for this takes place virtually without force against a conical wire spring (10) with a low spring constant. <IMAGE>

According to the invention, the compressed-air chamber (20) is designed in the form of a ring or ring segment, in such a way that it extends over the inner circumference of the shield, specifically expediently around the cutting head (12) in front of the transverse wall (7, 8). A space-saving overall arrangement is obtained in this way. If the inner space of the shield cutting edge (3) is utilized for the compressed-air chamber (20), the latter takes up virtually no space. <IMAGE>
