Title: Self-propelled agricultural implement
Inventor: ANDLINGER RUDOLF ING
IPC: A01B69/00
Filed: 1981-01-23
Abstract: The invention relates to a steering device for self-propelled agricultural implements and relates, in particular, to single-axle motor mowers with two driving wheels or to chain-side (delivery) rakes with two driving wheels and two steerable supporting wheels. To steer the implement, the driving-wheel drive shafts, each of which has a friction clutch and a friction brake, can be actuated by a handle bar by decoupling or decoupling and braking one drive shaft by means of separate actuating elements. In order to allow such an implement to be handled effortlessly by means of the handle bar, especially on steep gradients, using a simple and precise steering system, each drive shaft is allocated an energy accumulator, preferably between the handle bar and the actuating elements, and, by means of the pivoting movement of a handle bar pivotable essentially about a vertical axis in known manner, this energy accumulator actuates the friction clutch with priority over the friction brake; the actuation of the friction clutch is furthermore adjustable by means of a limit stop. <IMAGE>

Title: Fuel injection device
Inventor: HONIG ERNST-AUGUST DIPL ING
IPC: F02B3/06
Filed: 1981-01-28
Abstract: The invention relates to a fuel injection device, especially for direct-injection diesel internal combustion engines, with an injection pump having a fuel feed pump and injection valves assigned to each cylinder of the internal combustion engine. A pressure boosting device, which comprises a spring-loaded stepped piston, the working chamber of which assigned to the larger end face is connected to the injection pump and the working chamber of which assigned to the smaller end face is connected to the outlet aperture of the injection valve, is connected to each injection valve on the inlet side. The stepped piston is divided into two part pistons, separately loaded by springs and assigned to the two end faces, of which the smaller part piston is designed as a valve device controlling the connection between a connecting duct passing axially through the larger part piston and a middle working chamber. In order to achieve an easier return of the stepped piston comprising the two part pistons on completion of the feed stroke, it is proposed that the middle working chamber be connected to a pressure chamber, acted upon by the feed pump, preferably to the casing inner chamber of a distributor injection pump. The connection of the middle working chamber to the high-pressure working chamber assigned to the smaller part piston may be made either by a line laid outside the smaller part piston and equipped with a non-return valve or, however, by a connecting line led directly through the smaller part piston. In the latter case the non-return valve may have a valve stem passing axially through the smaller part piston, on the one end of which stem a valve disc acts closing the aperture of the bore and on the other end of which a valve spring acts, supported on the face facing the larger part piston. Finally the valve stem of the non-return valve and the bore enclosing this may be designed as an edge-type filter.

Patent DE-3112656-A1 (DE)
Inventor: FICK WOLFGANG
IPC: G09G1/02
Filed: 1981-03-31
Abstract: A character generator which converts character code words into data items, namely column code words (C code), for controlling a dot matrix output unit, is disclosed. The character code word is presented to an address memory circuit which generates a ten-bit-long column address (CAD) that identifies the locations of the column code words within a separate data storage unit. The address memory circuit includes two memory units (PROM 1, PROM 2) which store only the first eight bits of respective column data addresses, while an additional memory unit (PROM 3) stores the remaining two bits of the respective column data addresses. A multiplexer (15) is used to select the correct two bits of each respective column data address from an eight-bit word output by the additional memory unit (PROM 3) at the same time an eight-bit address is being output by one of the first two memory units (PROM 1, PROM 2). The ten-bit address thus output by the address memory circuit is applied to the data storage unit, which may be built up by using commercially available programmable read-only memory units (PROM 4, PROM 5, PROM 6), as may the address memory circuit. For a further utilization of the storage capacity of the additional memory unit (PROM 3) of the address memory circuit, the first eight bits of additional column data addresses may be stored therein. These first eight bits are then fed to the data storage unit by way of a switching amplifier (14), with the multiplexer (15) supplementing the additional column data addresses with two bits which are zeros in order to produce a ten-bit address.

Title: Machine for shaping spectacle frames by means of profiles
Inventor: GARDOSI VALTER
IPC: B21D11/10
Filed: 1981-04-11
Abstract: The invention relates to a machine for shaping spectacle frames by means of profiles. The main characteristic of this machine lies in the fact that it uses a grip device for advancing the profile, which grip device has an alternating displacement movement resulting from a crank and connecting rod system of variable crank radius. Over the entire stroke length of the said device, the rectilinear configuration of the profile is maintained by means of a guide which is made up of two roller belts which in turn lie over one another in a symmetrical manner in order to form a rectilinear guide track in which the profile runs. In each case one end of the belt is secured on the said device. The belts run along guide tracks which lie parallel to the stroke of the alternating movement of the said device and which separate and distance themselves from one another at the end point of the said stroke. <IMAGE>

Title: Process for purifying waste water and plant for carrying out the process
Inventor: EICHHOLZ GUENTER ING GRAD
IPC: C02F3/12
Filed: 1981-04-18
Abstract: A process for purifying waste water, in particular domestic waste water, is described in which the waste water is largely freed from entrained solids by mechanical discharge of the same and directly after, dispensing with the use of a settling tank, the waste water, together with the sinkable solids still contained therein, is passed into a first biological purification stage acting by the trickling filter or contact aeration process. In a second downstream biological purification stage, the waste water is treated in a simultaneous pond, in which an aeration of the waste water takes place in the region of the air incorporation in turbulent circulation flow, and settling of the sinkable solids proceeds in an area having laminar flow outside the air incorporation. The solids having dimensions of 1 mm to 3 mm, separated from the waste water by a fine screen or fine sieve, are transferred directly to the simultaneous pond so that no digestion tower is required.

Patent DE-3130705-A1 (DE)
Title: Arrangement for controlling a traffic light system by means of vehicles
Inventor: HILDEBRANDT BERNHARD ING GRAD
IPC: G08G1/087
Filed: 1981-08-03
Abstract: In this arrangement, the vehicles are provided with devices for automatic location finding (locating). The remote control for the traffic light continuously transmits microwave signals for requesting a green phase in the area close to an intersection. The operation of the entire system can be disturbed, particularly when the traffic is slow or at a standstill, due to the fact that microwaves are continuously radiated simultaneously by a number of vehicles. To prevent such a system disturbance, the invention provides a route-dependent control of the arrangement for location identification and traffic-light control. This is done in such a manner that a distance pulse derived from the vehicle causes the single switchable transmitting oscillator, provided for the required operating functions, of the interrogation device (Figure 1) located in the vehicle to be switched on and off. <IMAGE>
Patent DE-3135461-A1 (DE)
Title: Safety device for safeguarding the gas lines of welding, cutting and soldering equipment from explosions and backflow of gas
Inventor: SIMSHEUSER KARL-FRIEDRICH
IPC: F23D14/82
Filed: 1981-09-08
Abstract: The safety device contains, in known manner, a pressure relief valve, a gas inlet valve, a gas backflow valve and a flame arrestor. The pressure relief valve piston is not only acted upon from the direction of the gas inlet passage but, at the same time, also on the other side by the operating pressure. The relative pressure equilibrium thereby achieved allows precise definition of the valve spring system irrespective of fluctuations in the operating pressure. The gas inlet valve is closed by means of a cylindrical spool; the operating pressure therefore acts radially on the closed valve, i.e. exerts no pressure in the direction of movement of the spool. After an explosion or some other gas backflow, the pressure of the valve spring is thus sufficient to initiate valve opening and, together with the fresh gas which subsequently flows into the spool, to completely open the valve. The pressure relief valve acted upon from both sides and the gas inlet valve equipped with a cylindrical spool make it possible for the first time to effect fully automatic cancellation of a pressure-controlled self-closure. The thermal self-closure takes place by means of a separately replaceable fusible element; the problems associated with the gas-tight sealing of such a screw-off element are solved by the use of the fusible element as the sealing body.

Title: Method for one- to three-dimensional measurement of jaw or jaw joint movements and device for carrying out the method
Inventor: KLETT ROLF DIPL PHYS DR DR
IPC: A61C19/04
Filed: 1981-09-16
Abstract: In methods for one- to three-dimensional measurement of jaw or jaw joint movements and devices for carrying out such methods, projection-related measurement errors may result due to the fact that the measuring device with emitter and receiver cannot be located in the joint but is arranged to the side of it. These projection-related measurement errors caused by geometric magnification or distorsion effects are corrected in that the measurement signals for the x direction, y direction and z direction are each multiplied by a factor. There is described a device with which the corrections can be made.

Patent DE-3143105-A1 (DE)
Title: Device for tilting the flap plate of a shut-off flap, especially of a fire-protection flap for ventilation systems
Inventor: WILDEBOER WERNER
IPC: A62C2/24
Filed: 1981-10-30
Abstract: The invention relates to a device for tilting the flap plate of a shut-off flap, especially of a fire-protection flap for ventilation systems, about a supported flap axis into a limit position which is blocked against pivoting back. Known shut-off flaps have a locking device for the flap plate which can be operated so that said flap plate cannot inadvertently be tilted by forces acting on the flap plate. Known locking devices are structurally and mechanically costly and complicated. A simple lock is made possible according to the invention in that the flap axis has a radially projecting first actuating lever, in that the free end of the first actuating lever is connected in a pivoting manner to the free end of a second actuating lever which is at right angles to the first actuating lever in each limit position and can be tilted by means of a drive element about a pivoting axis which is aligned parallel to the flap axis, and in that a pivoting connection, which is common to both actuating levers, is guided such that it can be displaced longitudinally on the first actuating lever. The construction according to the invention of the device for tilting the flap plate has the advantage that, although the first actuating lever can also be tilted by the torque transmission at the common pivoting point of the actuating levers, driving the flap plate with it, when the second actuating lever pivots about its pivoting axis, the forces acting on the flap plate cannot, however, tilt the first actuating lever since this is prevented by the second actuating lever, which is aligned at right angles to it. The flap plate is thus locked in its limit positions, no special locking elements or the like being required for this locking.

Title: Cooling device on blow-moulding machines for cooling the upper flash on hollow articles
IPC: B29C49/58
Filed: 1981-11-07
Abstract: The invention relates to a cooling device on blow-moulding machines for cooling the upper flash on hollow articles. In order to ensure that even the flash which, given the way in which customary blow-moulding machines operate, protrudes upwards over the blow mould is also cooled, it is proposed by the invention that the cooling device squeezes together this still plastic material of the upper flash onto the mould or onto a cooling plate fitted onto the mould, spreads it apart and thereby cools the upper flash. The cooling device is preferably integrated in the movement sequence of the mandrel and/or forms a self-contained unit with the mandrel holder. The cooling device is equipped with springs, which ensure any compensation which becomes necessary.

Title: Method and device for applying upper and lower limiting parts on a slide fastener chain
Inventor: MORITA TOYOO
IPC: A44B19/60
Filed: 1981-11-16
Abstract: A method is described for attaching upper and lower limiting parts (2, 3) to a slide fastener chain (1) in one and the same manufacturing stage. The slide fastener chain is moved along a path until a rear end of a preceding pair of coupling member groups reaches a first stationary swage (16), at which point in time the front end regions of a subsequent pair of coupling member groups are uncoupled. While the rear end of the preceding pair of coupling member groups is retained at the first swage, an adjacent pair of opposite stringer tape regions without coupling members is deflected until the front uncoupled coupling members reach a second stationary swage (17) which is arranged along the path at a particular distance from the first swage. Subsequently, a lower limiting part (3) and two upper limiting parts (2, 2) are simultaneously attached to the rear end of the preceding pair of coupling member groups at the first swage or to the uncoupled front regions of the subsequent pair of coupling member groups at the second swage. A device (10) for carrying out this method is likewise disclosed. <IMAGE>

Title: Clamshell grab with movable and controlled grab cutting edge for excavating stable soils
Inventor: BALLHAUS HERIBERT DIPL ING
IPC: E02F3/413
Filed: 1981-12-15
Abstract: The invention relates to an improved clamshell grab with movable grab cutting edge for excavating stabilised soils. The motion sequence of the cutting edges is positively controlled in such a way that the grab teeth form an acute angle with the formation when the grab is fully open, so that the grab automatically digs into the soil under the action of the closing force. During the closing action, the angle of application of the cutting edge decreases so that the cutting edge forms a continuation of the clamshell base when the grab is fully closed. <IMAGE>
