Title: Adjustable electropneumatic hammer drill - incorporates system to vary stroke of piston which actuates hammer head
Inventor: GEIS WILHELM DIPL ING
IPC: B23Q5/027
Filed: 1989-07-07
Abstract: The electro-pneumatic hammer drill has a piston (26) which is actuated by a connecting rod (23) and a crankshaft (12).  The crankshaft (12) has a crankpin (19') which is formed integrally with a block (19) which fits in a diametral slot (18) formed in the end face of a boss (17) which forms part of the crankshaft. The crankshaft (12) has an axial bore (22) which receives an inner shaft (21) which has an end part (21') which is inclined at an angle (alpha) to the main part and engages an oblique hole (20) in the block (19).  The inner shaft (21) can be locked in either of two axial positions by means of a ball catch (29) so that the end part (21') is moved further into or out of the oblique hole (20) in the block (19) to provide two different radial positions of the crankpin (19') and so vary the stroke of the piston (25). USE - Hammer drills.

Title: Appts. for redn. of vol. of biological sludge - has cell structure of sludge is broken down by mechanicaldisintegrator and resulting material is subjected to further biological treatment
Inventor: KUNZ PETER PROF DR
IPC: C02F11/00
Filed: 1990-09-28
Abstract: Vol. of a biological sludge is reduced by mechanical disintegration followed by biological treatment. An initial biological treatment stage may be used before the mechanical disintegration. The disintegrated sludge may be anaerobically stabilised and a usable gas recovered, or may be aerobically stabilised. The disintegrated sludge is passed into a sedimentation vessel from which the floating solid material is decanted and passes to the biological treatment stage. The remaining liq. is subjected to a separate biological treatment, which may be in an already existing treatment unit. Disintegration takes place by use of high pressure or by grinding, and the sludge may be passed through the disintegrator a number of times before going to the biological treatment. Floatation in the sedimentation vessel may be by means of the evolved gases, or air or oxygen. USE/ADVANTAGE - In the disposal sludges e.g. from existing biological water treatment plants. The biological cell walls in the sludge constituents are broken up by the mechanical treatment so that the sludge can be reduced in vol. by a further biological treatment process and eventual disposal of the residual material is thus made easier.
