摘要： The shaft (1) rotates within two sealing rings (21, 11) equipped with static seals (20, 10) and separated by a gap (13) limited by the spring (23). The smaller ring (11) has, in its face (113) recessed (4) machined by a laser beam to tight tolerances w.r.t. unequal radii of their inner and outer edges (412, 411). The shgorter edge (411) faces the space (31) to be sealed. Recesses with mirror-image symmetry about the radius are equally effective under rotation in either direction. ADVANTAGE - Leakage is prevented and lubrication of the relatively moving surfaces is promoted by hydrodynamic pressure.

摘要： ZnO-eugenol cements contain, in addn. to ZnO and MgO, other oxides which combine with ZnO and/or MgO. 2-20% of Ti may be added, the rest being Zn and Mg. The ratio of Mg: Ti is 0.5-15, the rest being Zn, and 3-40% of TiO2 is added, the rest being ZnO and MgO. Prepn. is by mixing and sintering the oxides. USE/ADVANTAGE - The cements have better pressure strength (300% greater than non-reinforced, and 75% greater than reinforced, commercial cements), controllable setting time, and lower water solubility (50% of that of commercial cements). The cements are used in prepn. of a metal alloy which is oxidised in the powdered state (claimed). They are used in dentistry.

摘要： The stacking and tilting system for drawers incorporates a steel-wire drawer with a transverse support frame and two sides welded to it. The support-frame consists of two cross-wires (1) the ends of which have downward bend V-shaped feet (2) on which are support struts (3) with grip-bars (4) and -wires (5). The sides each have a U-shaped projection (8) with transverse support arms (9). The base-wires (7) are bent up at right angeles as corner bars (10) with locking arms (11). Support rails (14) fixed to tilting support angle-pieces (15) have semiround cavities (13). The angle-pieces (15) have guide-slot (16). A guide/support bracket (18) with bottom edge acts as the top edge of a parallel guide slot (16). A hook (19) has a horizontal locking-slot (21). USE/ADVANTAGE - The removable dishwasher cutlery boxes can be used as serving trays.

摘要： Pedal-crank drive with two chain circuits lying one behind the other in the power flow and a shiftable chain gear in the primary circuit, and having a front sprocket arranged in an axially displaceable manner in this circuit. In order to avoid the off-course running of the chain from the front sprocket to the individual pinions, the drive is divided up into two chains lying one behind the other in the power flow. The two circuits jointly use an additional spindle which receives the torque via the chain and the gear-shifting pinions and transmits it via the secondary front sprocket and the secondary chain to the rear-wheel pinion. In addition to this chain the primary chain circuit includes the axially moving primary front sprocket and the additional joint spindle with the pushed-on gear-changing pinions. At the same time, this spindle including the secondary front sprocket belongs to the secondary chain and the rear-wheel pinion belongs to the secondary chain circuit. The axially displaceable primary front sprocket is in each case displaced into a position which lies opposite the gear-shifting pinion occupied by the primary chain. As a result, the ideal chain line is always maintained. The secondary chain runs from the secondary front sprocket to the driving pinion of the rear wheel. Here too the ideal chain line is maintained.

摘要： Sliding ring seal for sealing the cooling water pumps of motor vehicles with a sliding ring 1, a clamping ring 2 and a spring 3, as well as a counter-ring 4 and a jacket ring 5. The clamping ring has an intermediate section 21 in the manner of a rolling bellows. A section 23 of the clamping ring is clamped in radially between the end coils 31 of the spring and the sliding ring. The spring has on the other side an end coil 34 with a smaller diameter which is located like a retaining ring radially resiliently in an annular groove 61 of the shaft 6. A transition region 33 of the spring engages positively in a recess 22 of the clamping ring. The jacket ring, which is inserted in the roller bearing outer ring 7, projects axially beyond the end face and with its radial bead 51 radially beyond the outer surface 71 of the roller bearing outer ring. The counter-ring has a conical transition surface 42 between its narrow sliding sealing surface 41 and its outer circumferential surface 43.

摘要： The invention relates to a tractor-operated working appliance with at least one implement (1) which is guided between plants (6a, 6b) of a plant row, especially between young trees or shrubs in or above the ground, whilst, as seen in the direction of travel (B) of the tractor, it is pivoted, at a specific distance in front of each plant, out of the space formed between adjacent plants and past the respective plant and, at a specific distance behind this plant, is pivoted into the space between this plant and the next following plant, in that a bar sensor (7) connected pivotably to the working appliance is moved counter to the force of a spring when encountering the respective plant and, via control means, initiates the pivoting movement of the implement (1). The object of the invention is to provide a working appliance of this type, which guarantees that, when the bar sensor butts against the bark of the plant for the purpose of controlling the movement of the implement, damage to the bark is reliably prevented. The object is achieved in that the surface region (9) of the bar sensor (7) coming into bearing contact with the respective plant is provided with bristles (10).

摘要： PCT No. PCT/EP87/00259 Sec. 371 Date Jan. 14, 1988 Sec. 102(e) Date Jan. 14, 1988 PCT Filed May 15, 1987 PCT Pub. No. WO87/06991 PCT Pub. Date Nov. 19, 1987.A seal comprised of a sealing ring (1) and a clamping ring (2) presses against the end face (3 ) of a machine part (3). The sealing ring surrounds a tubular part (12), close to the low-pressure end of which are formed a narrow sealing ridge (131) and a support part (11). The axial thrust exerted on the sealing ring (1) is transferred essentially by the support part (11) via the elastomer clamping ring (2) to the end face (31), so that the sealing ring (11) can yield in a floating manner against radial movements of the opposite operating surface. The pressure to be sealed off acts both via the clamping ring (2) on the one side and, an annular groove (422) on the other side of the tubular part (12), so that the sealing surface is essentially relieved of its load.

摘要： The invention relates to a hydraulic seal for pistons and rods with at least one sealing ring and one clamping ring. According to the invention, the sealing ring is of particularly dimensionally stable design. The radial height of the sealing ring is preferably 1.5 times to 3 times greater than its axial width. Two sealing rings are preferably installed in one groove dimensioned for a single sealing-edge ring of the conventional type. They act in tandem, with an intermediate store, in a very small space.

摘要： The invention relates to a shaft seal which, in a known, labyrinth-like manner seals off by means of splash rings and collecting channels a shaft exit subjected to splashing liquid or surging liquid and in which the passage of air, dust or liquid mist is prevented by the installation of a contact seal between a rotating part and a stationary part of the seal, ahead of the last collecting space on the air side and by the installation in the collecting space itself or in the return passage connecting the collecting space to the space to be sealed off of a restriction element which allows through the small leakage flow from the contact seal and at the same time has a high resistance to the flow of air.
