Abstract: A flip-flow screener machine includes a carrier frame with primary, drive-induced vibration, to which a vibrating frame is coupled in a freely oscillating manner by means of elastic transmission elements and is excited and set to vibrate secondarily by the carrier frame via said transmission elements, transverse carriers being arranged on the carrier frame and on the vibrating frame, a transverse carrier on the vibrating frame lying downstream of a transverse carrier on said carrier frame, with a flexible screen bottom being arranged between two transverse carriers and detachably secured to said transverse carriers, each of the screen bottoms including at least one undercut portion by means of which they can engage behind an undercut on the transverse carrier, and two adjacent screen bottoms abutting one another directly at their front ends.

Abstract: A method is for inserting a further data block into a first ledger, the first ledger including data blocks. In an embodiment, the method includes receiving a further medical dataset via an interface; determining the further data block via a calculation unit. The further data block includes the further medical dataset and a further link information. The further link information includes a hash of at least one of the data blocks of the first ledger.

Abstract: Locking arrangement for locking a first element which is movably mounted in a first direction, by means of a second element which is movably mounted in a second direction transversely with respect to the first direction. First element has a toothed contour with at least two teeth and a tooth gap which lies between. Second element has a projection which has a projection length which is shorter than the tooth gap length. The projection can be introduced into tooth gap when there is movement in the second direction, to lock the first element. Each tooth has a face which points towards the second element and has a first contour. Projection has a face which points towards the first element and has a second contour. First and second contours are matched to one another so that the projection is deflected by the teeth from becoming inserted into tooth gap if first element moves faster than a predetermined locking speed and slower than a maximum speed of first element.

Abstract: An electrical characteristic in an operator-sensing circuit having a microcontroller that commands a charge sensor to send a sensor charge signal to a capacitive sensing element. The charge sensor outputs a corresponding raw data signal to the microcontroller that in turn sends a signal that disables the motor of a unit power equipment upon the absence of an operator's hand on a hand-gripping surface of the equipment. Capacitive means for operating within a predetermined charge range that includes preselected values that designate hands-off and hands-on conditions on the hand-gripping surface. The capacitor charge range is effective to distinguish between the presence of an operator's hand and foreign material on the gripping surface for avoiding a false hands-on-signal.

The first element has a toothed contour with at least two teeth and a tooth gap which lies between them. Tooth gap has a tooth gap length in the first direction. The second element has a projection which has, in the first direction, a projection length which is shorter than the tooth gap length. The projection can be introduced into the tooth gap when there is a movement in the second direction, in order to lock the first element. The teeth each have a face which points towards the second element and has a first contour. The projection has a face which points towards the first element and has a second contour.

Abstract: What is proposed is a variator disk for a toroidal variator, in particular for a motor vehicle toroidal transmission. The variator disk has a curved running surface which is oriented coaxially with respect to a variator axis and on which rollers of the toroidal variator can roll. The variator disk having furthermore at least two partial disks which are designed as a traction disk, on which the running surface is formed, and as a supporting disk, respectively. The supporting disk is designed for supporting axial forces applied to the running surface. The traction disk is supported on the supporting disk in the radial direction to the variator axis.

Abstract: A calibrated operator-sensing circuit having a microcontroller that commands a charge-transfer sensor to send a sensor charge signal to a capacitive sensing electrode. The sensor receives a discharge signal from the electrode and outputs a corresponding raw data signal to the microcontroller that in turn sends a signal that disables the motor of a unit of power equipment upon the absence of an operator's hand on a hand-gripping surface of the equipment. The capacitive operator-hand sensing electrode operates within a predetermined output capacitor discharge range that includes preselected binary digit values that designate hands-off and hands-on conditions on the hand-gripping surface. The capacitor discharge range is effective to distinguish between the presence of an operator's hand and foreign material on the gripping surface for avoiding a false hands-on signal.

Abstract: Process for exchanging an intermediate roll in a calender and a calender. The calender has more than three rolls arranged to form a pressing plane obliquely oriented at a predetermined angle to a vertical, the intermediate roll to be exchanged being positioned immediately above a neighboring roll. The process includes lowering the neighboring roll at least a distance h defined by the equation: h=(r1+r2)(1−cos &agr;), in which r1 is a radius of the intermediate roll, r2 is a radius of the neighboring roll, and &agr; is the predetermined angle, and substantially horizontally removing the intermediate roll to be exchanged.
