Patent DE-3712477-A1 (DE)
Title: Hydraulic, adjustable shock absorber
Inventor: PREUKSCHAT ALFRED DIPL ING
IPC: B60G17/015
Filed: 1987-04-13
Abstract: Shock absorber for vehicles, in which a damping element is provided, which has a working cylinder, divided into two working chambers by a piston, for receiving a damping medium, a solenoid-actuatable and axially movable valve body of a valve acting on a flow passage at least some of the time in order to control the damping force. The intention in this is to permit a variable damping adjustment, it being possible to arbitrarily adjust the damping of the tension and compression stage by way of a variably controlled damping valve. In addition, it is intended to be able to influence the switching, frequency, closing and opening behaviour of the valve body, designed as armature of a solenoid, by varying the effective, hydraulically influenced functioning surfaces of the valve body. In order to solve the problem, a seating face arranged approximately at right angles to the axis of rotation of the valve body forms a valve seat together with the end face of the valve body, at least one part of the end face of the valve body and of the valve seat being arranged at a distance from one another. By means of this design, a partial pressure reduction influencing the valve body is obtained in the area of the valve seat.

Title: Safety connection flange for a robot-guided tool, in particular an electric welding tool
Inventor: PITSCH ANDREAS
IPC: B23Q5/58
Filed: 1987-05-25
Abstract: A safety connection flange for welding robots has a link to the welding tool consists of a robot-side connection part (10) and tool-side connection part (12), which are constructed as flanged rings and engage one inside the other with annular generated surfaces. The generated surface (22) of the one connection part (10) is constructed as a sphere; the generated surface (26; 28) of the other connection part (12) is configured in its inner region as a hollow cylinder and in its outer region as a hollow sphere. Locking members (46) distributed at the circumference of the second connection part engage resiliently in recesses (48, 50) of the first connection part (10) and hold the parts (10, 12) in the normal position relative to one another. If the tool comes up against an obstacle, the parts (10, 12) are deflected out of their normal position and cause an initiator arranged in the region of the generated surfaces to produce a switch-off signal for the robot. <IMAGE>

Title: Pole-changeable synchronous electrical machine
Inventor: FISCHER DIETER DIPL ING
IPC: H02K19/12
Filed: 1988-02-12
Abstract: If a synchronous machine having a salient-pole rotor (1) is changed from 2p1 poles to 2p2 poles, then problematic excitations of vibrations of the laminated stator core can result. For this reason, a minimum number of elementary poles (4) is fixed for the construction of the salient-pole rotor (1), which number results from products of prime factors of both pole pair numbers p1 and p2, obtained by adhering to a selection rule. The elementary poles (4) to be energised in the same direction or changed, in the case of both pole numbers, are then each combined to form a constructionally realised pole (4, 5, 6, 7), whose size corresponds to one elementary pole (4) or a multiplicity thereof. <IMAGE>

Filed: 1988-08-20
Abstract: A circuit for deriving line, field and picture sync pulses from a three-level sync signal S of a high definition television signal comprises means responsive to rising edges of the sync signal S to generate respective pulses each having a leading edge defined by a rising edge crossing the zero level of the sync signal and a trailing edge defined by the rising edge crossing a reference level (+50%) intermediate the zero level and the maximum positive level of the sync signal, such means being enabled at the beginning of each line to generate a line sync pulse H, Fig 3A, in response to a rising edge of the sync signal then occurring but being inhibited from responding to any further rising edges of the sync signal occurring thereafter for greater than half a line duration whereby only one line sync pulse is generated per line. The circuit further comprises means for detecting end-of field, Figs 3A and 3B, and end-of-picture, Fig 3B, defining components of the sync signal occurring during the first half of the last line of each field and for generating a field sync pulse C when either such component is detected, the field sync pulse being substantially longer, Fig 3B, when such end-of-field defining component is also an end-of-picture defining component than when it is not, and means for detecting each such longer field sync pulse to generate a respective sync pulse. <IMAGE>

Title: Electrochemical cell
Inventor: BORGER WALDEMAR DIPL CHEM DR
IPC: H01M8/2465
Filed: 1988-10-01
Abstract: In an electrochemical cell (1) having a structure in the form of layers, intermediate spaces are formed between the negative and positive electrode plates (2, 4) by means of auxiliary frames (3) in order to move the electrolyte, and these intermediate spaces are supplied with electrolyte via central lines (8, 9, 10, 11) and duct-like holes (not visible) which branch off from the corners (5, 5) (which are in the form of ears) of the auxiliary frames to the intermediate spaces. When the central lines (8, 10) are connected to the pressure side of an electrolyte pump, flow passes through the plates in the direction of the arrow, and when the central lines (10, 11) are connected to the pressure side (the other central lines in each case to the suction side), an electrolyte circulation takes place, with charging gases being extracted at the same time. The uniform electrolyte flow is always distributed in the diagonally rising direction over the electrode plates. <IMAGE>
