Abstract: A method of bone cement preparation from a polymeric powder and a liquid component including a polymerisable monomer or comonomer by the action of a catalytic system. Particles of the powder are packed in a powder container having an inlet and an outlet port, while the liquid component is held in a liquid container. The liquid container is connected to te inlet port and a vacuum source is connected to the outlet port. A voided space between the powder particles is flooded by the liquid component that flows form the inlet port toward the outlet port under the influence of the vacuum source.
Abstract: A manually operated tool of the type in which a grip is pivotally mounted in a housing displacing a push rod mounted in the housing in an axial direction and in a stepwise manner. The push rod extends through at least a pair of canting blocks arranged between bearings supporting the push rod. A spring resting on the housing acts on the portions of the canting block through which the push rod extends. The force applied by the spring on the canting blocks is directed against the direction of displacement of the push rod. An adjusting force periodically exerted by the grip acts on the outer portions of the canting blocks remote from the push rod. At least one braking block is provided for holding the push rod.
