Abstract: A hub (2) is rigidly torsionwise attached to a leading shaft (1) but free to move axially and radially. A rotary plate (3) is arranged on said hub (2) through a ball bearing (21) and carries a ring (4) provided with four conical transmission surfaces (30, 31). The transmission surfaces (30) of the ring (4) run on surfaces (33) of two rims (7, 8) of a wheel (6) integral with the casing, and the transmission surfaces (31) run on surfaces (34) of two rims (10, 11) of a second wheel (9) attached to the driven shaft (12) and coaxial with the wheel (6). The distance between the rims (7, 8 and 10, 11) is adjustable. When the driving shaft (1) rotates, the ring (4) effects a slow oscillation motion about the leading shaft (1) and transmits such motion to the wheel (9). The two transmission ranges are offset by 180.degree.. The eccentricity is adjustable between a maximum and zero, which allows the obtention of a reduction up to the infinite. A toothing may be provided in the transmission areas.

Abstract: In an automatic bending machine, a box-like housing is provided in which a central driving wheel is mounted for reciprocating a plurality of slide units fastened at the front wall of the housing. The front wall is a front plate which together with the slide units can be easily removed from the housing and replaced by another one the slide units of which having been set up before at another place. A plurality of interchangeable front plates can be set up with slide units and tools. Each of the front plates is provided for a work piece of predetermined form. The front plates not in use can easily be stored for a replated use.

Abstract: The invention is concerned with apparatus for a game of tether ball in which a bolt member is mounted on a pole and a ball is attached to a line which is attached at its other end to a nut member rotatable on the bolt member so that the point of attachment is up or down the bolt member according to the direction of travel of the ball after being struck by a bat, an element is being provided inside the bolt portion which is biased for movement in one direction which has a formation adapted releasably to receive a locking formation which is released in one or the other of the winning positions of the game by passage of the nut past such winning positions.

Abstract: Apparatus for molding curd in calibrated portions, a mixture of curds and whey, introduced into a hopper, fills perforated tubes in which the whey is separated from the curd and becomes compact. A plate closing off the base of the tubes retracts periodically and the curd drops abruptly by a predetermined height onto a subjacent plate, which is sliced by the first plate returning to its original position. The slices of curd are then transferred into one of the molds with a plurality of cells. This is applicable to the manufacture of cheeses of small size.

Abstract: In a hydrodynamic brake, forming an energy converting mechanism and used for example in connection with heat-exchangers in the utilization of wind-power installations, the torque characteristic of the hydrodynamic brake is adapted to suit the torque characteristic of the power source by making the stator radially displaceable into a position in which its axis is off-center from the axis of the rotor. The stator is eccentrically secured on a shaft and by rotatably mounting the shaft, in the housing, eccentrically of the rotor. In an alternative embodiment, the stator is guided in a rectilinear guide permitting radial displacement.

Abstract: A telescoping shaft which is displaceable in the axial direction with low force wherein the inner shaft and hollow shaft are connected by guide pins swivelly connected to the shafts.

Abstract: A milling cutter consists of a shaft 10, a cutter plate 12 and a screw bolt 14 by means of which the cutter plate 12 is detachably fastened at the front end of the shaft 10. The latter has a recess in the front face thereof. The recess is defined by three planar side faces leaving a peripheral gap between each pair thereof. The cutter plate substantially formed triangularly is fitted in the recess for being inmovable in a radial plane. Protrusions 30 of the cutter plate protrude through the gaps and are provided with a cutting edge respectively.

Abstract: In an automatic punching and bending machine the interspace between the bending device and the punching device is adjustable in order to make the interspace as small as possible and to adjust that interspace in dependence on the length of the working piece of a band material, thereby gaining the advantages that series of different work pieces of high precision can be produced in the same machine. The bending device is removable and can easily be replaced by another one which has been reset in a preceding working process. Therefore standstill periods of the machine are reduced.

Abstract: A ski waxing machine comprises a housing with an oblong opening in the upper wall. The length and the width of the opening corresponds to the length and the width of a pair of skis arranged side by side. A plurality of supporting elements are arranged within the housing and project into the opening. The skis secured on the feet of a skier are supported by the supporting elements. A guide block can be reciprocated within the housing carrying waxing devices, which project upwards into the opening. The supporting elements can be temporarily removed out of the moving path of the guide block and waxing devices upon approach thereof and are automatically reset into the supporting position after the guide block has passed.

Abstract: A drill chuck consists of a two-piece housing, a two-piece insert and a cage for a plurality of jaws. The two pieces of the housing are threaded together. The rearward piece thereof is a fastening sleeve. The two pieces of the insert are in threaded driving engagement. The front piece is held against rotation and is only shifted axially in order to open or close the mouth formed by the jaws. The rearward piece of the insert is held against axial displacement and can be rotated by inserting a key through a bore of the housing from the rearward side thereof.A drill can be clamped in the chuck and then the chuck with the clamped drill can be inserted in a driving shaft of a drilling machine.

Abstract: A hacksaw machine comprises an upper and a lower horizontal bracket, a swinging arm in each one of the brackets and a driving mechanism for pivoting the lower swinging arm. A saw-blade connects the front ends of the swinging arms. The lower swinging arm is twice as long as the upper arm. Both swinging arm are tensioned in opposite directions by springs respectively which are adjustably fastened at the brackets. The swinging mechanism is independent on the lengths of the brackets.

Abstract: Described herein is a carrying device for pot plant cell units, which device comprises a frame (1) supporting the cell units containing the pot plants to be planted, which frame (1) can be, by means of a side arc (9) fastened to same, supported to the waist of the planting person and, on the other hand, by means of harness consisting of belts (14, 16, 19, 20), to the upper body of the planting person. A shoulder belt (14), which passes from the breast side of the planting person across one shoulder to the back side, is at the breast side and at the back side, by means of front and rear connecting rings (17, 17'), connected to a side belt (16) passing around the other side of the planting person. At the breast side of the planting person, the frame (1) is fastened to the front connecting ring (17) by means of a short front belt and, at the back side of the planting person, to the rear connecting ring (17') by means of a longer rear belt (20).

Abstract: An anode for electrolysis includes an electrically conductive bar erected on an electrolytic cell bottom plate, opposed anode bodies connected to the electrically conductive bar through anode supporting bodies, and reinforcing bodies provided between the opposed anode bodies and outside the anode supporting bodies.
