Patent DE-3636871-A1 (DE)
Title: Piston/cylinder unit with position indicator
Inventor: LANDES ROLF
IPC: F15B15/28
Filed: 1986-10-30
Abstract: In order to be able to effectively utilise the advantages in particular of electronic control systems, sensors are necessary which are able to signal state variables and changes. An inductive proximity switch (11) is arranged on the cylinder housing to detect the position of a piston rod of a piston/cylinder unit, while an annular constriction is formed in the chrome coating of the piston rod at a predetermined location of the same for specific damping of the proximity switch. The proximity switch, which is at a certain distance from the surface of the piston rod, has a working switching gap of, for example, 0.6 mm in the area of the relatively thick chrome coating but is, for example, 0.7 mm from the surface of the piston rod. At the location of the relatively thin chrome coating, the working switching gap of the proximity switch is, for example, 0.81 mm. In this area, damping of the proximity switch is thus effected, and the proximity switch thereby produces a switching signal. <IMAGE>

Patent DE-3726684-A1 (DE)
Title: Roots vacuum pump
Inventor: RIETSCHLE WERNER
IPC: F04C29/04
Filed: 1987-08-11
Abstract: The Roots vacuum pump has two rotary pistons (1, 2) rotating in opposite senses in a pump chamber (3). An intake (6) ends at the interface between the two part-cylindrical pump chamber halves (3a, 3b). Opposite the intake (6) there are two or more outlet discharge channels (10, 12) that end on both sides of the transition edge (5) between the two pump chamber halves, and whose outer ends can each be closed by non-controlled discharge valves (14, 16) that open and close in response to the pressure differential between the pump chamber and the outlet channel (10, 12). The achievable pressure differential between the intake and outlet is increased by the separate discharge channels (10, 12) with associated discharge valves (14, 16). An improved removal of the heat of compression is achieved by feeding in a coolant through a slide valve controlled by the rotary motion of the rotary piston. <IMAGE>

Title: Relief network for electronic branch pairs in a reverse-parallel circuit
Inventor: KLEMM HELMUT ING GRAD
IPC: H02M7/515
Filed: 1988-07-09
Abstract: A relief network is proposed for electronic branch pairs in a reverse-parallel circuit of a converter, in the case of which network the losses which are produced especially during the switching-off process are reduced. A GTO thyristor or a transistor with a diode connected in reverse-parallel or a reverse-conducting thyristor which can be switched off is used as the branch pair. Two series-connected storage capacitors (6, 7) are arranged between the terminals (DC voltage source) (1). The common junction point (12) of the two storage capacitors (6, 7) is connected via a turn-off relief capacitor (8) to the common junction point of the two branch pairs (2/4, 3/5). The further connections of the branch pairs in each case are connected to the terminals of the DC voltage source (1), it being possible to connect current-limiting inductors and/or fuses in between. <IMAGE>
Patent DE-3826310-A1 (DE)
Inventor: NAGEL ROLF
IPC: B21D5/04
Filed: 1988-08-03
Abstract: The main starting point was that the workpiece (13) can be clamped between two holding punches (11, 12) designed as counter tools, a link (18) carries, at its two jaw edges, in each case one of two bending tools (24, 26), and a drive device (20) for essentially vertical tool movements is provided outside a drive device (19) for essentially horizontal tool movements. The intention is, with a small outlay, on the one hand to permit rapid switching to the other bending tool, and, on the other hand, to offer ample space for bending workpiece parts projecting a long way. The link (18) is therefore divided, in a manner of a hinge, into two cheeks (16, 17) which can pivot separately about the link axle (23) and each carry one of the two bending tools (24, 26), and a drive device (20, 21) is articulated on each of the two cheeks (16, 17) for essentially vertical tool movements. The drive device (20) assigned to the upper bending tool (24) is preferably designed for the larger maximum travel. The bending device can be employed universally in an enlarged field of use since wider plate flanges and, ultimately, more complicated edge profiles can be produced. <IMAGE>
