Title: Crankshaft big end bearing oil system - has pocket in shells extending before connecting rod centre line
Inventor: KEYLWERT JOHANN DIPL ING
IPC: F16C3/14
Filed: 1979-05-18
Abstract: The system supplies lubricating oil to a crankshaft big-end bearing, having an oil supply pocket (10) formed in the bearing shells (8, 9). In the peripheral direction this extends for 90 to 180 deg. in front of the centre line of the connecting rod (4) when seen in the direction of rotation of the crankpin (3), and in the axial direction symmetrically over a considerable part of the bearing width. One or more oil feed passages (13) are formed in the shells, in the same peripheral area as the pocket, to which they are connected. An annular passage (14) extends outside the shells and round the crankpin, being connected on the one side to these passages, and on the other to a fresh oil passage (15) in the crankshaft (1) and the crank web (2).

Title: Electronic organ with improved ambience - uses resonators formed by loudspeaker assigned to tuned resonant pipes at controlled temp.
Inventor: KIENLE EWALD
IPC: G10H3/20
Filed: 1979-06-18
Abstract: What simulated organ music usually lacks, partic. in the region, is adequate spatial coupling between the electro-acoustic transducers and the surrounding air. A mere increase in audio intensity cannot make up for this lack because it would overemphasize the impression of a one-dimensional source of the music and moreover, tends to overload the transducer in the preferred frequency ranges which still the output. To overcome this a loudspeaker is assigned to a series of tuned , such as pipes, there being twelve in each octave, pref. in an indoor environment with controlled temp. The fundamental of a tone as well as all the harmonic components are individually amplified by the appropriate resonance cavities so that a relatively very large air volume linkage exists with the auditorium. The cavities may consist of thin-walled plastics pipes. of 8 to 15 cm diameter.

Title: Yarn brake - has reduced rotor mass to give rapid stop action on yarn break
Inventor: BROSA ERICH
IPC: B65H59/16
Filed: 1979-07-19

Title: Heat flow measurement for heating cost distribution - using double regulator valve with correction from return flow temp
IPC: G01K17/08
Filed: 1980-03-07
Abstract: A heat quantity measurement device, esp. for determining the distribution of heating costs. of a hot water heating system, is economical, accurate enough for heating cost purposes, and enables reduced cost data readout expense through reducing the number of readout points. A thermally controlled double regenregulator valve allows flow to the throughput measurement device and prevents flow past it according to the temp. of the medium. Both flows are corrected by two further valves which are controlled by the return flow temp. via a thermoelement. Alternatively, the flows are corrected by the double regulator valve under the control of the return flow temp. Instead of, or as well as, a mechanical counter there is an electromechanical or electronic counter receiving pulses via a switch.
