Patent DE-3204088-A1 (DE)
Title: Connecting fitting for two plastic pipe ends
Inventor: JESCHKE IMMANUEL
IPC: F16L47/04
Filed: 1982-02-06
Abstract: In the case of a connecting fitting for two plastic pipe ends, especially for gas-transportation pipelines, it is intended to achieve the object of creating a connecting fitting which is suitable for connecting plastic pipe ends, guarantees absolute sealing and is designed such that the fitters just need to push the pipe ends into the fitting and then tighten the clamping nuts. The invention achieves the object in that the sleeve inner wall is divided on both sides of the centre plane into three different sections, of which the outer has an internal thread for the clamping nut to be screwed into while the section which is adjacent to the interior holds the sealing elements, in that the sealing elements rest with their external circumference tightly against the internal circumference of the sleeve in the Section C and have an internal diameter which is somewhat larger than the external diameter of the pipe end of the supporting sleeve, while the external diameter of the sealing elements is equal to the internal diameter of the sleeve section allocated to them, and in that the flange of the supporting sleeve tapers conically outwards.

Title: Flow-divider valve
Inventor: PFEIFFER JOACHIM DIPL ING
IPC: F15B13/02
Filed: 1982-03-27
Abstract: The invention relates to a flow-divider valve which splits the incoming total flow into two partial flows, in particular of the same size, and for this purpose utilises a balance piston, the control edges of which control the flow cross-sections between control spaces and consumer connections in such a way that, during a pressure rise at one consumer connection, the flow cross-section to the other consumer is reduced. The inflow from an inflow connection into the control spaces is effected via restrictors. Flow-divider valves of this type divide the total flow irrespective of load changes at the consumers in proportion to the restrictor cross-sections. According to the invention, that consumer which is the first to exceed a predetermined pressure level is now to be supplied as a matter of priority. For this purpose, auxiliary pistons loaded by preloaded springs are arranged on either side of the balance piston at a certain distance apart, which auxiliary pistons each have an effective area which acts against the springs and is acted upon by the pressure of the associated control space in such a way that the balance piston is displaced into a position separating the other consumer connection from the control space. In a preferred application, the level-regulating devices of the front wheels or the front axle and of the rear wheels or the rear axle of a vehicle are supplied with pressure medium from a single pressure source.
Patent DE-3214031-A1 (DE)
Title: Automatic, double-acting excess-pressure safety device for plate-spring differential manometer
Inventor: TEICHMANN GERHARD
IPC: G01L13/02
Filed: 1982-04-16
Abstract: The invention relates to an automatic, double-acting excess-pressure safety device for protecting the elastic measuring member of plate-spring differential manometers. The aim of the invention is to produce at minimum cost the double-sided protective function for the measuring member and transmission and indicating system up to the full static operating pressure. According to the invention this is achieved with a double-acting valve which is arranged in the centre of the measuring member and at the same time assumes the kinematic output function of the measuring member. The kinematic output element (1) carries the valve disc (2) which is pressed by the spring (3) onto a stop seat. It preloads the sealing element (5) and determines the zero setting of the output element (1) relative to the measuring member (9) in the valve seat (8). The compression spring (6) pulls the valve disc via the subassembly (7-1-4-3) against the inner cone of the valve seat (8). The stops (10 and 11) block the output element (1) in the zero and end position. Excess pressure in the "-" chamber causes the valve to open by forcing the split valve cone (2) from its seat, which the sealing element (5) follows. In the event of excess pressure in the "+" chamber, the valve opening is initiated by the stop (11) after the stroke of the measuring member is exceeded. <IMAGE>

Patent DE-3223100-A1 (DE)
Title: Address-free fault locating in transmission links for digital signals
Inventor: DOEMER JOSEF ING GRAD
IPC: H04B17/40
Filed: 1982-06-21
Abstract: In transmission links for digital signals, the location of a fault can be determined by closing a loop between two regenerative repeaters for two signal paths following a received loop closure command and transmitting via this loop test signals which are examined for errors at the receiving end by bit-by-bit comparison with the test signals sent out. The test signal used is normally a pseudo-random sequence which must not exceed a certain length in order to avoid synchronisation problems in the bit-by-bit comparison at the receiving end. It has been found that fault-locating is not possible in every case using this method. According to the invention, an additional pseudo-random sequence of comparatively very long periodicity is therefore additionally combined with the existing test signals, but at the receiving end, only an evaluation for code rule violations is carried out. This method is applied in particular in transmission links for digital signals with higher transmission rates. <IMAGE>

Title: Permanent-magnet excited unipolar stepping motor
Inventor: PFEIFFER GEB JAGLA
IPC: H02K37/18
Filed: 1982-08-09
Abstract: A new rotor design is proposed in order to improve the utilisation of permanent-magnet excited unipolar stepping motors. In this case, the rotor has a special damper winding which suppresses oscillations which endanger operation. Furthermore, in the case of a plurality of rotor stack pairs, the polarity sequence of the permanent magnets is varied such that inactive intermediate spaces between the rotor stack pairs can be omitted. Finally, magnetically conductive, solid sleeves are fitted between the rotor laminate stacks and the non-magnetic shaft, which sleeves make improved guidance of the magnetic flux possible. These improvements can be used individually on their own, or jointly, with particular advantage.
