Patent DE-3800916-A1 (DE)
Title: Field control for an electrical machine having permanent magnets in the excitation part
Inventor: WEH HERBERT PROF DR
IPC: H02K1/27
Filed: 1988-01-14
Abstract: The moving excitation part is assigned (separated by an air gap) to a stator having an invertor-supplied, multi-strand armature winding. The permanent magnets in the individual pole arrangements are formed from layers of magnetic material (I/II) having different B/H characteristics in the second and third quadrants, which have a highly curved, narrow hysteresis loop (a, b). The armature coils which are in each case centrally assigned to the pole centres have flux passing through them briefly, in the sense of producing a desired change in the field intensity of the permanent magnets, the series connection of the individual layers of the permanent magnets being controlled in the energising or deenergising sense by means of a current pulse (which acts on the pole gap between adjacent poles) of the relevant armature winding parts. <IMAGE>

Title: Double-ply sheeting for seals in hydraulic engineering or the like
Inventor: SCHUHBAUER ALBERT DIPL ING DR
IPC: E02B3/16
Filed: 1988-01-25
Abstract: A double-ply sheeting serves for seals in hydraulic engineering or the like, preferably for sealing off refuse landfill sites. The sheetings are joined to one another by seams dividing into zones, the chamber-shaped zones being filled with a substantially non-rotting, cushioning material which keeps the sheetings spaced apart. In order for considerable immunity to leakages to be ensured even in the event of the sheeting plies becoming damaged, the material (3) consists of a substance which is caused to swell by the ingress of water and which has a sealing effect in the swollen state (Fig. 1). <IMAGE>

Filed: 1988-05-18
Abstract: By rotating a bending roll (10) in the pipe bending direction, a pipe bend portion (11a) held in a sandwiched state by a pressure die (13) and a block member (14) is bent around a circular section of the bending roll (10) as it emerges from between these members. The outer bend periphery section of the pipe (11) is under the axially compressive force of a pressurizing means (16), which by a top (16a) abuts an outer edge of the pipe, and undergoes a change in such a manner that the elongation ratio thereof is restrained. Further, the inner bend periphery section of the pipe (11) undergoes a change in such a manner that wrinkle generation on the surface thereof is prevented by the elongating tensile force exerted by the block member (14) and the core bar (17), such prevention being aided by a wrinkle checker (18) on the core bar (17). The pipe has a bend radius of down to its diameter. <IMAGE>

Title: Cooling water regulator for internal combustion engines
Inventor: WAHLER DIETER DIPL ING
IPC: G05D23/13
Filed: 1988-05-27
Abstract: A cooling water regulator for internal combustion engines is proposed, with a thermostatic valve with expansion element thermostat for actuating the valve element of the main valve controlling the valve seat for passage of the cooling water between radiator and internal combustion engine. The tappet of the main valve is supported on a thermostatically controlled actuating element, which has a control element adjacent to the expansion element thermostat and a remote temperature sensor, separated from the control element and connected to this by way of a remote transmission element, which is arranged closer to the radiator outside the heat-affected space, so that the remote temperature sensor actually senses the radiator outlet temperature and not, say, a related temperature distorted by heating in the area of the cooling water regulator. As a result a more accurate adjustment of the regulating characteristics of the thermostatic valve as a function of the radiator outlet temperature can be achieved.

Title: Welding head
Inventor: EICHHORN FRIEDRICH PROF DR ING
IPC: B23K9/12
Filed: 1988-08-17
Abstract: A welding head, which is suitable in particular for narrow-gap welding, has a guide tube (12) for the wire-shaped electrode and a supporting tube (14) surrounding the guide tube (12). Fastened to the bottom end of the supporting tube (14) is a contact element (18) which laterally deflects the electrode (10) after the latter has left the guide tube (12). The degree of lateral deflection of the front electrode end (10b) can be changed by moving the guide tube (12) relative to the supporting tube (14), so that the electrode tip can be set laterally without the entire welding head having to be rotated. As a result, work can be carried out in a dragging and neutral manner as well as in a piercing manner relative to the welding direction in each position. <IMAGE>

Title: Method and arrangement for comparing objects in reflected light
Inventor: SCHWEITZER DIETRICH DR
IPC: A61B3/12
Filed: 1988-09-16
Abstract: The invention relates to a method and an arrangement for comparing objects in reflected light by using a polarising prism with additional prisms. During the image comparison of two objects, disturbing reflections are to be avoided in the reflected light. One object (13, 15) is illuminated in each case by one polarised beam (7, 8) each, the beams being polarised at right angles to one another. To produce the images (20, 23) which overlap in the image plane (19), only those reflected light components (17, 22) are used which oscillate perpendicularly to the plane of oscillation of the respective illumination beam (7, 8). Manually and/or automatically matching the arrangement preferably produces an image formation (image, imaging) which is unreversed, has the correct size and is overlapping. The use of the invention is of particular advantage in ophthalmology, in particular for the simultaneous inspection of both eyes of the patient or when comparing one eye to a previously stored image of the same eye. The invention likewise permits to compare the desired states and actual states of workpieces during development and production and the positioning of workpieces. <IMAGE>

Title: Method and device for the control of a multicylinder internal combustion engine
Inventor: BRANDSTETTER WALTER DR
IPC: F02D41/00
Filed: 1989-04-25
Abstract: A method for the control of a multicylinder internal combustion engine and a device for performing the method are described, the cylinders of the internal combustion engine being shut off by interruption of the combustion in the cylinders in order to limit the speed in the event of predetermined engine speed limits being exceeded. In order to achieve a more favourable performance in the speed reduction range and to improve the tractive power behaviour of the internal combustion engine when shifting up, it is proposed that the cylinders be shut off individually or in groups at differing engine speed limits, the number of cylinders or groups of cylinders shut off increasing with rising engine speed limits. For this purpose it is proposed that a measuring device (9) registering the speed of the internal combustion engine (1) and a control device (8) connected to the measuring device be provided for triggering a cylinder shut-off device (7), which can be actuated in order to shut off a first cylinder or a first group of cylinders when a first engine speed limit is exceeded and in order to shut off further cylinders or groups of cylinders when further engine speed limits are exceeded. <IMAGE>
Patent DE-3918091-A1 (DE)
IPC: E01B29/28
Filed: 1989-06-02
Abstract: The invention concerns a rail fastener on concrete ties (4) or the like including resilient tension clamps (6) of steel rods in the form of a W and angled guide plates (3) for the rail base (1a). This so-called HM rail fastener is inventively improved by a special shaping of the tension clamp and angled guide plate, to simplify the securing of the rail on the concrete ties, in that the rotation of the elastic strainers which was previously necessary in HM construction when passing from the preassembly to the assembly position is omitted. This is achieved in that the angled guide plate (3), which is provided with a rib (3a) extending longitudinally to the rail foot for abutment on the rail foot (1a), contains in this rib special recesses (3b) for the reception and retention of the free ends of the tension clamp in the preassembly position. A tension clamp (6) has outer legs (6b) which with expansion of the spacing from the inner legs (6d) against the rail foot (1a) become broader and their free ends (6a) end outside the middle portion (6e) and wherein the inner legs (6d) of the tension clamp (6) which surround the tie screw (5) are designed so that in the preassembly position they abut with their center portion (6e) the shaft (5a) of the tie screw, while the head (5b) of the tie screw (5) overlaps the inner leg (6d) in the assembly position. In a special embodiment, the tension clamp is so designed that its center portion permanently surrounds the tie screw (5), and its inner leg portions are brought together except for a small spacing.
