Abstract: Apparatus for forming a twist knot in the ends (7) of wire (2) passing around a bundle (1) of rods or a large bundle of smaller bundles of rods has a head (3) which is rotatable about an axis (9) and carries a pair of arms (4) which are pivotable towards and away from the axis (9). The arms (4) have slots (6) to receive and hold the wire ends (7) so that when the head is rotated the ends are twisted together into a knot. 
     To provide a simple mechanism avoiding the need for control of the movement of the arms and to render the apparatus versatile, the arms (4) are substantially freely movable about their pivots (5), so that they are pulled inwardly by the wire ends themselves, during the initial period of rotation of the head.

Abstract: A fluid energy grinding mill having a hollow vessel (12) providing a central cylindrical core zone (44) and a peripheral annular zone (46) both disposed beyond a grinding zone at one end of the vessel. Carrier medium is injected (at 15) into the grinding zone to generate a vertically-flowing vortex in the core zone. At the other end of the vessel, a first portion of the flow from the vortex is recirculated in a counter flow through the annular peripheral zone surrounding the core zone to interface with new injected carrier medium in a grinding zone. A second portion is discharged through a central opening (26) in the other end of the vessel. Particulate material is fed into the recirculating flow trough a feeder (35) so that it may be comminuted in the grinding zone. In the vortex, the particulate material is classified by centrifugal action and the coarse particles are recirculated. The particles ground to the desired mass are discharged through an outlet (22) with the second portion of the carrier medium which is not recirculated. Several forms of regulation are disclosed for regulating the upwardly-flowing vortex and the portion of the flow which is recirculated.

Abstract: Infrarot-Einbruchdetektor, der als Sensorelement ein pyroelektrisches Detektorelement (P) verwendet, erfolgt die Auswertung des Ausgangssignales des Detektorelementes mit einem Ladungsverstärker (Q), beispielsweise mit einem kapazitiv gegengekoppelten Operationsverstärker (OP), dessen Ausgangssignal in bestimmten Zeitabständen rückgestellt wird. Die Auswerteschaltung arbeitet unabhängig von der Detektorkapazität und gestattet daher, die pyroelektrischen Eigenschaften optimal auszunützen. Durch den Kurzschlussbetrieb und die Niederohmigkeit der Schaltung wird eine besonders gute Unempfindlichkeit gegen äussere Störungen erreicht, sowie ein geringes Rauschen und eine erhöhte Empfindlichkeit.
