All the regions to be machined can consequently be covered in one operation. The workpiece according to the invention can be produced substantially more cost-effectively by eliminating various machining operations. <IMAGE>
Patent DE-3442179-A1 (DE)
Title: Length of sewer pipe for an adjustable plug-in connection
IPC: F16L17/03
Filed: 1984-11-17
Abstract: The invention relates to a length of sewer pipe for an adjustable plug-in connection, in the case of which one end of another pipe can be plugged into a face end of the length of sewer pipe and, by means of a sealing ring located therebetween, is sealed and can be fixed so as to be capable of displacement. The conventionally used rolling ring which is secured, if appropriate, in a peripheral groove in the length of sewer pipe, or in the end, to be plugged in, of the other pipe, is easily shifted out of position and jammed when adjusting the plug-in connection, as a result of which not only is adjustment hindered but, in addition, the necessary sealing is at risk. This is avoided according to the invention in that the sealing ring in the plug-in direction of the pipe end is supported in a positively locking manner on the face end of the length of sewer pipe, with the result that the sealing ring cannot be shifted out of position or jammed when plugging in the end of the other pipe.

At least one wall section 26, 28 of each annular working chamber preferably adjoins an associated air or combustion mixture inlet section, the engine housing 12 being divided in the area of this wall section. <IMAGE>
Patent DE-3506651-A1 (DE)
Title: AC motor
Inventor: BESSHO KAZUO
IPC: H02K19/08
Filed: 1985-02-26
Abstract: The invention proposes an AC motor which consists of a combination of a magnetic frequency tripler and of a rotor which can be used for an induction motor. The AC motor has a core (1) which consists of three limbs (2, 3, 4) two of which limbs (2, 4) are used as input limbs around which input coils (12, 15) are wound and which at the same time form a linear inductor coil and a saturated inductor coil. The inductor coils are connected in series. The remaining limb (3) is used as the output limb, which produces a magnetic flux at three times the frequency, in that a single-phase input is applied to the input limbs. A squirrel-cage rotor is arranged, such that it can rotate, in a cylindrical gap which is formed in the output limb. The squirrel-cage rotor is thus driven in a stable manner at a relatively high rotation speed which corresponds to the synchronised speed which is determined by the tripled frequency with respect to the frequency of the AC current which is supplied from a commercially available power-supply system. <IMAGE>

Patent DE-3518384-A1 (DE)
Title: Fence mount
Inventor: MICHEL KURT
IPC: A63K3/04
Filed: 1985-05-22
Abstract: The invention relates to a fence mount having a continuously vertically adjustable bar support, especially for equestrian sports or other types of jumping sport. As such mounts are generally very heavy, and as a rule have to be transported by two people in each case, the aim is to make it easier to transport them. It is proposed that the fence mount be designed so as to be movable when pulled approximately in the direction of the tipping angle when its base (1) and a bar support (2) connected to the said base (1) are tipped about a single-axle undercarriage (4) which is arranged in the region of a peripheral boundary of the mount base (1). <IMAGE>
Patent DE-3519092-A1 (DE)
Title: Tandem vane motor
Inventor: KASPER FRANK DR
IPC: F01C1/077
Filed: 1985-05-28
Abstract: The invention carries the title >>Tandem vane motor<<. It describes an internal combustion engine in which the reciprocating pistons of conventional engines are replaced by two pairs of vanes, which are supported on a common shaft and function in only one direction of rotation. The movement of the pairs of vanes is controlled by way of an elliptical gear mechanism so that the intervals of the vanes of both pairs constantly vary. In this way four chambers sealed off from one another are produced in the engine compartment. Conversion of the forms of motion from a pulsating rotary motion of the pairs of vanes into a uniform rotary motion of the drive shaft is performed by way of a guide rail of the elliptical gear mechanism. The purpose of the invention is to improve the efficiency of internal combustion engines in that the pairs of vanes are supported on a shaft and moved without stopping in only one direction of rotation. <IMAGE>

Filed: 1985-07-16
Abstract: In a process for obtaining haemoglobin products, a haemoglobin oligomer with a narrow molecular weight distribution is obtained by reacting a haemoglobin solution to a limited extent with an amino group-specific reagent which makes the haemoglobin crosslinkable, and subsequently crosslinking, directly or indirectly, the haemoglobin modified in this way.
Patent DE-3534142-A1 (DE)
Title: Typewriter or office machine of a similar design for optionally recording normal script or braille script
Inventor: WEMPEN HELMUT
IPC: B41J3/32
Filed: 1985-09-25
Abstract: For sighted persons to produce braille script, known typewriters are operatively connected to embossed script machines which permit parallel pieces of text to be produced in braille script and in normal script. Since in this case two separate machines are connected to one another, correspondingly high costs are involved. The invention is based on the object of designing typewriters or office machines of a similar design in such a way that they can write either in braille script or normal script directly or from the memory. This object is achieved by means of a switching device by means of which drive bits can be optionally called up from the memory and fed to the printing device in order to produce braille script and normal script on the recording carriers. In this process, a blind person is able to produce a piece of text in braille script and parallel thereto in the memory. Subsequently, the contents of the memory can then be printed out in normal script. Sighted persons can on the one hand use the machine for normal script and on the other hand are able to produce a sheet of braille script from the memory. <IMAGE>

Patent DE-3545846-A1 (DE)
Title: Three-phase motor protection circuit breaker
Inventor: KOHL LUDWIG DIPL ING
IPC: H01H71/10
Filed: 1985-12-23
Abstract: A three-phase motor protection circuit breaker produces simultaneous disconnection of all the phases in the event of an overcurrent, a short-circuit current or a phase failure occurring in at least one of the phases. In this case, the current paths of the individual phases are allocated power chambers (12, 13, 14), which are placed side-by-side and are separated from one another, from which in each case one first tripping lever (16, 17, 18) projects with a deflection as the current load increases, as does a second tripping lever (20, 21, 22) with a deflection when a short-circuit current occurs. The individual power chambers and their tripping levers are located with respect to one another such that the three first tripping levers form a first row (19) of tripping levers running transversely with respect to their deflection direction, and the second tripping levers form a second row (23) of tripping levers running parallel thereto and at a distance therefrom. Allocated to the power chambers which are located side-by-side are common tripping kinematics (27) which are composed essentially of functional groups or functional elements named in the following text, specifically: of a receptacle housing (69) and a covering element (15), of a base slide (28), of a central lever (52) and of two guide levers (61, 62). 
<??>As an alternative to this, a phase failure slide (97) and a pivoting lever (112) which is supported on the base slide can be used instead of the central lever and the two guide levers.

Title: Pressure generator for a hydraulic system
Inventor: POESCHL GUENTER
IPC: F15B21/06
Filed: 1986-04-08
Abstract: Instead of being designed in the conventional manner as a pump, the pressure generator is here designed as a refrigerating machine (8) with two working cylinders (14, 14'), each of which contains a floating piston (16, 16'). The two pistons (16, 16') are in each case connected on one side to the one or the other side of a third working cylinder (24) via hydraulic lines (22, 32). On the opposite sides (a, a') of the pistons (16, 16'), refrigerant is in each case in connection with the suction or pressure side (or vice versa) of the refrigerating compressor (10). The pressure generator works with a better efficiency than the otherwise conventional pump, because heat energy irradiated from outside can be utilised for evaporating the refrigerant in the evaporator (12). An increased temperature of the pressure medium delivered by the pressure generator does not manifest itself here in heat due to energy losses, but is converted into useful kinetic energy by means of the working cylinders (14, 14') connected to the refrigerating compressor (10). <IMAGE>

Title: Open-end spinner sliver loosening roller
Inventor: STAHLECKER FRITZ
IPC: D01H4/32
Filed: 1986-04-25
Abstract: Sliver loosening roller has a clamping disc which is free from the main body of the roller. It is fitted directly to the shaft, and centered.Pref. the inner surface of a clothing ring is fitted with a recess at the end face towards a flange of the body of the roller, against a projection on the body surface. The recess is a ring groove and is deeper than the level of the projection. The clamping disc is drilled to pass over the projecting shaft over the roller body, to be held axially and centred by a screw engaging a threaded drilling in the shaft. The clothing ring ranges axially towards the clamping disc above the roller body, and is held radially by the roller body. The outer side of the clamping disc has a dish-shaped recess to take the head of a fixing screw so that a head flange can bear against a clamping surface of the disc. The stem of the screw head is narrower to form a gripping edge, with notches to allow a tool to engage it.The threaded drilling of the shaft to take the mounting screw, extends as a lubricant drilling at least as far as the vicinity of a bearing, where at least one lubricating branch channels off to the bearing. The flanges of the roller body and the clamping disc have sections with a radial extension at least as far as the zone of the points of the clothing ring. The flange of the clamping disc has spring flexibility in an axial direction against the clamping surface taking the pressure of the mounting screw. The surface of the circumference of the roller body has spring resilience

The production costs of the surface box (1) are thus reduced considerably. <IMAGE>
Patent DE-3618016-A1 (DE)
Title: Water softening device for water-bearing domestic equipment, in particular for dishwashing machines
Inventor: ENNEN GUENTHER DR
IPC: A47L15/42
Filed: 1986-05-28
Abstract: In a water softening device for water-bearing domestic equipment, in particular for dishwashers, having an ion exchanger vessel and a salt container which can be filled from the dishwasher interior, which is provided with a closable salt filler nozzle, and from which the salt brine for regeneration is forced via a connection duct into the ion exchanger vessel equipped with an outlet for used salt brine and soft water, the salt filler nozzle is surrounded on the outside by a collection channel for overflowing salt brine. A brine outlet bypassing the dishwasher bottom branches off from the collection channel. Such a measure advantageously achieves the fact that brine displaced from the container on filling the container with new salt no longer comes into contact with the dishwasher bottom. Corrosion of the dishwasher surface by the highly concentrated aggressive salt brine is thus no longer possible, even after a relatively long idle time of the domestic equipment, since all of the salt brine flushed out can be trapped by the collection channel and also can be returned back to the water softening device.
