Patent DE-4123060-A1 (DE)
Title: Torsional oscillation suppression system - is for IC engine crankshaft and uses rotating eccentric masses
Inventor: BOLZMANN JOERG DIPL ING
IPC: F16F15/22
Filed: 1991-07-12
Abstract: The IC engine has a crankshaft (2) which is mounted in a housing. The crankshaft (2) passes through the central hole in a non-rotating gearwheel (3) which is fixed to the housing.  The crankshaft carries a disc (4) which has four equally spaced axially projecting lugs (19,20,21,22). These lugs (19,20,21,22) form bearings for rotating masses 9-12 which rotate about axes (5,6,7,8) which lie in a common plane which is at right angles to the crankshaft axis. Each mass (9,10,11,12) has an attached gearwheel (14,15,16,17) with helical teeth which mesh with the helical teeth of the fixed gear (3). The axis of each mass is eccentric to its centre of gravity. As the crankshaft (2) rotates each mass  rotates about its own axis (5,6,7,8) so that the moment of inertia of the crankshaft is continously changing and so suppresses torsional oscillations. USE - Vibration suppression for IC engine crankshaft.

Title: Double piston pump for spraying wet concrete or mortar - uses alternating pistons with changeover link to pump material and sensors to detect end of stroke
Inventor: MANNHART OTHMAR
IPC: F04B/
Filed: 1992-05-11
Abstract: The double piston pump comprises two cylinders (1,2) connected to the hopper (5). The pistons alternate in direction so that there is suction in one cylinder and pumping in the other. During the pumping stroke, the cylinder concerned is connected to the delivery pipe (8) by a two-way connection piece (10) which swings within the hopper. The pistons are moved by piston rods connected to pistons in separate hydraulic cylinders with pressurising pump. In the hydraulic circuit, each cylinder has a sensor which detects when its piston is at the end of its stroke and this sends signals to valves to direct the hydraulic pressure to the other sides of the pistons, and also to change over the position of two-way link. The pistons complete their suction stroke before the completion of pumping stroke in order to avoid air-locks. ADVANTAGE - Smooth delivery of spray material.

Title: Activating PTFE surfaces to enable adhesive bonding - by treatment with high energy ion beam
Inventor: FREY HARTMUT DR ING
IPC: B29C35/08
Filed: 1992-06-16
Abstract: PTFE surfaces are activated to enable them to be adhesively bonded to other PTFE surfaces or to the surface of other materials, by expousre to high energy ion beam with an energy of greater than 10 keV. Pref. the PTFE parts are exposed to ion beams of one of the elements H2, O2, He, N2, Ar, Kr, Xe, Ti, Ni, Cr, Al or Fe at a dose of 10 power 15-10 power 20 particles/cm2 and an energy of 100-200 keV. The ion beam treatment may be carried out using metallic elements such as Cu, Pa, Cr, Al, Ni or Ti to give PTFE with an electrically conductive surface which can be subjected to electrochemical treatments. Ion beam treatment with ions e.g. from SiO2 or Al2O3 gives a sealed, scratch resistant, storage stable surface for later bonding. USE/ADVANTAGE - The ion beam treatment is more environmentally friendly than the previously used activation treatment of treating the surface with a sodium-ammonia cpd., and causes activation of the PTFE surface by cracking the -CF2- chains with release of F and formation of C radicals which act as adhesion sites.

Title: Device for movably arranging a hand-held, motor-driven tool
IPC: B23Q11/00
Filed: 1993-06-23
Abstract: A device for movably arranging a hand-held, motor-driven tool is illustrated and described, having a cantilever arm, a holding arm including tool receptacle arranged thereon, a pulling device, as well as a parallelogram-link arrangement. The object of the invention is to provide a device which has a pulling device which automatically adapts in every working position and, moreover, presents less danger of injury to the user. The solution to this object results essentially in the fact that the moment resulting from the product of the force applied by the pulling device multiplied by the rectangular distance between the line of application of the tensile force and the centre of rotation of the holding arm necessarily adapts, at each inclined position of the holding arm, to the moment resulting from the product of the weight of the holding arm and of the tool multiplied by the respective rectangular distance of the weight, acting at the centre of gravity, from the centre of rotation.
