Patent DE-3640018-A1 (DE)
Title: Drinking-water throughflow fitting
Inventor: URNER CLAUS DIPL ING
IPC: E03C1/10
Filed: 1986-11-24
Abstract: A combined pressure and flow control device (18) has two diaphragms (38, 76) which are in drive-connection with one another in one direction via push rods (49, 50). One diaphragm (38) is actuated by the differential pressure and the other diaphragm (76) is actuated by the static pressure at the outlet, with the result that both the differential pressure and the static pressure trigger a displacement of the push rods (49, 50) and thus the actuation of a proximity switch (20), advantageously a flow of medium through the combined pressure and flow control device (18) not being necessary (Figure 3).   <IMAGE>

Title: Heatable or coolable hydraulic accumulator
Inventor: PEIFFER JOACHIM
IPC: F15B1/08
Filed: 1986-12-16
Abstract: Heatable or coolable hydraulic accumulators have hitherto been produced in that a heating chamber or cooling chamber was welded onto the outside of a commercially available hydraulic accumulator. Apart from the fact that not all materials are weldable, welding often impairs the dynamic strength. Immersion in baths cannot always be applied for reasons of space. The hydraulic accumulator is provided on the outside with a sealing surface onto which is pushed a housing part which is fastened to the hydraulic accumulator with the aid of a shoulder nipple and a nut and has at least one liquid connection. Pulsation damping in hydraulic systems with heating of highly viscous liquids or cooling of hot liquids for protection of the membrane or bag situated inside.

Patent DE-3739480-A1 (DE)
Inventor: GRAS RAINER DR
IPC: C07C275/26
Filed: 1987-11-21
Abstract: Direct reaction of polyisocyanates and polyamines occurs vigorously and uncontrollably. It is therefore necessary to use the polyisocyanate in blocked form. In previously known processes, it has not been possible to obtain the desired semi-blocked adducts; instead, relatively large portions of completely blocked product in addition to unreacted polyisocyanate were obtained. The further reaction with polyamines was unsuccessful. 
<??>The preparation of blocked, urea-containing polyisocyanates has been made possible by using semi-blocked polyisocyanates, which are formed by the addition of blocking agent to a manifold excess of polyisocyanate, followed by thin-film distillation and subsequent reaction with polyamines in an NCO/amino group ratio of 1 to 1.3:1 to 1.1. 
<??>The blocked, urea-containing polyisocyanates are used in particular for PUR paints.
Patent DE-3742135-A1 (DE)
Title: Device for determining the position of a machine tool or robot axis
Inventor: GROHMANN THOMAS DIPL ING
IPC: G01D5/245
Filed: 1987-12-11
Abstract: To determine an axis (A) of a machine tool or robot, which is driven via a gearbox (G) by a motor (M), a distance pulse transmitter (W) is provided on the motor side which, apart from pure distance pulses (I), also delivers reference pulses (RI) for synchronising the distance measurement. If the transfer ratio (a/b) of the gearbox (G) is so chosen, that the number of distance increments (I) per axle revolution (n) is not an integer multiple of the number of distance increments per transmitter revolution, the angular position to which the reference pulses refer changes after each revolution. This displacement is continuously detected so that a reference position can be approached during each revolution of the axis (A). <IMAGE>

Title: Modulo-10 counter which supplies the count in 54321 code
Inventor: MERKLE PAUL
IPC: H03K23/50
Filed: 1987-12-22
Abstract: The modulo-10 counter according to the subject-matter of the invention is a pulse counter which supplies the count in 54321 code, and the decades of which only exhibit 4 simple counting flip flops each. At the first to fourth counting pulse, a further flip flop in each case switches to its left-hand position. At the fifth and tenth decade counting pulse, flip flops 11 to 14 are reset and dual flip flop 20 is switched to its other position. At the fifth decade counting pulse, flip flop 15 switches to its left-hand position and, at the end of this counting pulse, flip flop 16 switches to its left-hand position. At the tenth decade counting pulse, flip flop 15 switches to its right-hand position and at the end of this counting pulse, flip flop 16 switches to its right-hand position. Using the pulse switching circuit 7 avoids that two or more counting flip flops switch to their left-hand position with a counting pulse. <IMAGE>
Patent DE-3800608-A1 (DE)
Title: Unipolar machine
Inventor: BEERWALD HANS DR
IPC: H02K39/00
Filed: 1988-01-12
Abstract: The invention relates to a unipolar machine, especially for producing heavy-current pulses, having a cylindrical rotor (1) which is mounted in a stator (4) such that it can rotate and consists of electrically conductive material through which a magnetic field passes, current pick-offs (6) being arranged on the outer circumference of the cylindrical rotor. In the case of such a unipolar machine, in order to reduce the wear on the current pick-offs (6) and at the same time to make it possible to switch the heavy-current pulses on at precisely the right time without any additional series switch, the invention proposes that the current pick-offs (6) be constructed as spark gaps which operate without making contact, are triggered by microwaves, and produce a plurality of spark channels when a microwave pulse is injected, just as a result of the microwave energy and irrespective of the voltage applied to the electrodes. <IMAGE>

Patent DE-3806909-A1 (DE)
Inventor: TUSCH FRANZ
IPC: H05B39/04
Filed: 1988-03-03
Abstract: A switched-mode power supply for a light source whose brightness is controlled, having a rectifier which produces a half-wave rectified voltage at first terminals, having a smoothing circuit which produces a smoothed DC voltage at second terminals, having two push-pull semiconductor switches, associated with a high-frequency generator, whose control inputs are each coupled to a transformer winding, and having a first switching element, which is coupled to the DC voltage input and is voltage-dependent, for triggering a semiconductor switch. The technical problem is producing a switched-mode power supply which permits brightness control by controlling the high-frequency generator without the high switching loads of phase chopping. A control input is fed via a first switching stage (81). A capacitor (44) with an adjustable load resistor (46) is connected to the second terminals (54, 55) of the DC voltage. The charging voltage of the capacitor (44) is applied to the input of a second switching stage (43) whose output switches off the first switching stage (81) and the voltage-dependent first switching element (15). A zero-voltage identifying circuit (56) is connected to the first terminals (5, 6) of the half-wave rectified voltage. The output of the zero-voltage identifying circuit (56) controls a discharge stage (57) for the charging capacitor (44). <IMAGE>

Title: Pump drive for fixed displacement pumps with mobile drive
Inventor: SCHOPF WALTER
IPC: F04C14/08
Filed: 1988-04-14
Abstract: Pump drive for one or more fixed displacement pumps for supplying hydraulic circuits with varying required quantities at different drive speeds, preferably for CVT drive concepts. It is used, on the one hand, to save pump drive power in the upper operating speed range (in the case of conventional excess pressure-medium delivery) and, on the other hand, to ensure sufficient pressure-medium supply in the lower operating speed range and otherwise critical operating conditions, such as start-up of motor and vehicle. According to the invention, the pump drive path is guided via a superposition gear, at the second outlet path of which there is arranged a further driven machine (electric machine or hydraulic pump), via the power regulation of which the pump speed can be varied and optimised according to requirements. The power produced in this power path can be usefully fed to the vehicle supply system by means of an electric generator or can be used to supply further minor hydraulic circuits by means of a hydraulic pump; it can also be returned to the drive path via motor-driven further electrical hydraulic machines. By integration of electric machines, forward running of the pump drive and thus also towing or tow-starting of motor vehicles with automatic transmissions is made possible.
Patent DE-3817691-A1 (DE)
Title: Method of removing special waste from a deposit site
IPC: E02D3/115
Filed: 1988-05-25
Abstract: To remove liquid or pasty special waste from a landfill site, freezing pipes (9) combined in a device (7) are driven from the surface and a freezing agent, e.g. liquid nitrogen, is fed through them. An ice mass (8) surrounding the freezing pipes (9) is thereby produced which, suspended on the freezing pipes (9), can be removed from the landfill site by means of a lifting device, e.g. the lifting rope (6) of an excavator (4). This enables special waste to be removed from a landfill site in portions in a simple manner without larger ice masses, for instance, having to be divided into individual, manageable portions, and thus the risk of any immissions is greatly reduced. <IMAGE>

Title: Device for separating products transported in an imbricated formation into groups
Inventor: STOERR RUDOLF DR
IPC: B65H33/12
Filed: 1988-09-17
Abstract: The invention relates to a device for separating flat products, preferably folded sheets, transported in an imbricated formation into groups in processing machines. To exert a periodic holding force on the products of the imbricated flow, pneumatic gripping elements, which may also be designed as a suction belt, are mounted so that they can be guided parallel and at a relative speed to the transporting belts. It is ensured by the device according to the invention that the imbricated flow is separated at a defined point, and that, by means of the even conveying of the first delayed sheet, irregular pushing-on of the folded products forming a bulge, thickening or pile-like structure is avoided. Owing to the step in the transporting belts, each product is placed, to a great extent without friction, on the new imbricated formation. <IMAGE>
