Patent DE-4305784-A1 (DE)
Title: Pressure-tight piston ring
Inventor: STALTMEIR JOHANN
IPC: F16J9/14
Filed: 1993-02-25
Abstract: Hitherto known piston rings of different cross-sectional shapes are slotted. The slot in the piston ring here constitutes a leakage point. The novel piston ring is intended to reduce these leakage losses caused by this to a minimum. The ends of the pressure-tight piston ring are constructed in the form of a tongue-and-groove pair (Fig. 1). The radial gap remote from the pressure is closed with a cover (Fig. 2). The cover of small thickness is firmly connected to one end of the piston ring. The pressure-tight piston ring is to be used for sealing off a piston in a cylinder from gases or liquids. <IMAGE>

Title: Heat exchanger for calorific value boiler - comprises ranks of finned pipes and the row facing the boiler burner is inclined at sixty degrees
Inventor: NOHREN HARTMUT
IPC: F24H1/40
Filed: 1993-03-02
Abstract: Hot water flows through a number of rows of finned pipes (1-14), one above the other, opposite the burner and inclined at an angle of sixty degrees with the horizontal. The water to be heated, that is the return flow, flows into the lower pipes and the heated water passes into the upper pipes and out through the flow connection, so that a continuous circulation follows. The upper (20) and the lower (21) walls of the combustion chamber (18) are water cooled through channels (22, 23) connected to the finned pipe (14). These upper and lower walls of the combustion chamber are of aluminium and take the form of inserts. ADVANTAGE - Maximum use is made of heat from exhaust fumes.

Patent DE-4315775-A1 (DE)
Title: Two-for-one twister spindle drive - has structured grooves in squirrel cage rotor for gentle starting and slow ballooning build=up
Inventor: PAWELETZ ANTON DR ING
IPC: H02K7/14
Filed: 1993-05-12
Abstract: The spindle for a two-for-one twister is a relatively low inertia spindle keyed to a squirrel cage rotor (3). It has a groove geometry where the web (11) to close the groove gives a timed saturation from the start of switching-on. When the nominal rotary speed is achieved, there is a low slip and a very stiff loading action. Pref. the slow start-up and the stiff loading action is determined by the depth of the grooves (10) in the rotor (3). The speed/time characteristic of the activated spindle follows an S-shaped path. The ratio of the web (11) width (bs) to the mean tooth width (bz) of the grooves (10) in the rotor (3) is set for the best performance where the dynamic start-up characteristic is gentle and the loading characteristic of the induction motor (4) is very stiff. The larger cross section of the deep grooves (10) is within a ratio of 0.05-1.2. The yarn is fed from below into the rotating unit of the spindle. The yarn emerges radially from a rotating twisting plate to form a yarn balloon round a fixed bobbin to the twisting point with an inner bobbin yarn. The force on the yarn is smoothed by the rotation of the spindle and the axial draw tension. USE/ADVANTAGE - The spindle, for a two-for-one twister, has a separate motor drive, with a small induction motor, energised separately from a stoppage from a group drive through a central frequency converter. The mechanism gives a gentle start to give the ballooning action, with a slow angular acceleration increase.
