Title: Breaker or drifter with piston action - has adjustable tool entry, crank or piston stroke adapts to application
IPC: B23B45/00
Filed: 1973-08-06
Abstract: Breaker, drifter, jackhammer etc. whose piston reciprocates off a crankshaft and rod in the cylinder so as to impact via spring or gas cushion a striker, and thus onto the endface of the tool shank where this enters the cylinder over a limitable path. It is possible to vary relative their maximum values either the stroke of the piston, and/or the penetration path of the shank or adapter into the cylinder and/or the length of the connecting rod involved in the piston drive. PEnetration of the shank can be shortened by a spacer ring thrust onto the shank between a limit stop and an end stop on the cylinder, or again the end stop can itself be adjusted for the same purpose. Another way of varying the impact force is to change the interval between the crank pin and the axis.

Title: Light expanded concrete contg. foamed plastic - where plastic is foamed in hot mixer directly before adding other constituents
IPC: C04B20/06
Filed: 1973-12-21
Abstract: In the process for making light expanded concrete contg. foamed particles of plastic together with other constituents, the plastic is fed to the mixer as a granulate and heated in the mixer to form foamed or expanded particles of plastic directly before the other constituents are added to the mixer. The plastic granulate is pref. added to a pre-heated mixer and, during the foaming process, a pressure slightly above atmospheric pressure is pref. maintained in the mixer. The process is designed to overcome difficulties experienced in the mixing of constituents which possess widely different specific gravities. When making expanded concrete plastics already foamed float on top of the remaining constituents in the mixt. and it is necessary to add a bonding agent, e.g. an epoxy resin, which is expensive; the present invention overcomes these difficulties. By foaming the plastic in the mixer immediately before adding the other constituents, it bonds readily with the cement and tests have shown that the bending strength of the finished expanded concrete with an apparent density of 0.8t/m3 is almost the same as that obtd. using pre-foamed plastic and an epoxy-resin binder.
