A centrifuge assembly incorporates a centrifuge bowl 1 having a filler piece 3 in which is formed an elongate channel 5. Removably disposed in the channel is a polyvinyl chloride tubular container 13 which conforms to the channel 5 and receives whole blood to be centrifuged so as to collect red cells, platelets and plasma. The channel 5 has two portions of which the first is wider than the second ...

A grinding head has at least one expandable grinding tube mounted on an expansion cone. The expansion cone is carried by, and is rotatable with, an expansion rod which is coupled for rotation with a driven part of the head. The expansion rod and cone are movable by means of a ram to cause expansion and contraction of the grinding tube. The connection between the ram and expansion cone via the expa...

A thread guide for guiding a thread between a bobbin of a warp or bobbin creel, from which the thread is payed-off, through a thread tensioner, while deflecting the thread through about 90 DEG in the direction towards a winding machine, is structured such that the thread, between its bobbin and upon leaving the creel, experiences a single deflection. This is accomplished by means of a deflection ...

A method and apparatus for use in the manufacture of pneumatic tires, in which a pair of tire bead assemblies are held in accurately spaced relationship against opposite ends of a tube. Tire carcass material carried on an expansible former is located within the tube and expanded to engage the bead assemblies, projecting ends of the carcass material being turned radially outwardly around the bead a...

The invention relates to an X-ray tomograph in which the X-ray tube can perform movements which are independent of each other in two directions at right angles to each other. The X-ray tube in a first support can be moved in the transverse direction which is connected to a second support extending in the longitudinal direction which in its main direction is journalled so as to be movable in a stan...

A household slicing machine wherein a disc-shaped knife is rotatable in a vertical plane in response to starting of an electric motor as a result of depression of a trip which is mounted in the housing of the slicing machine. The trip can be depressed only when a detachable guard for the knife is held in an intermediate position in which the guard and an abutment for the foodstuff to be sliced def...
