Title: Electric generator installed in human body - has bonded piezoelectric plastic films connected by rectifiers to supply heart pacemaker
Inventor: KIESLING ERNST
IPC: A61N1/378
Filed: 1976-08-13
Abstract: The electric generator is installed in the human body for supplying electrical circuits e.g. for a pacemaker consists of bonded piezoelectric plastic films which are placed in parts of the body frequently subjected to a change in pressure and which are connected by rectifiers. Pref. several film sections are connected in series, and. the films are arranged one above the other in a sandwich construction. A current store device of high capacitance is connected to the output of the rectifier, to provide a d. c. voltage even with LF feed currents and to allow bridging of longer intervals at the above parts of the body e.g. near the heart or lungs. Due to pressure fluctuation stress on the film it produces a low-power a.c. voltage sufficient for supplying pacemaker circuits which conventionally require very low supply energies.

Title: Projectile trajectory corrector polarisation system - has sensor for synchronised rotating polarisation reflector on projectile
Inventor: SIEBECKER HANS DIPL ING DR
IPC: F41G7/30
Filed: 1976-10-30
Abstract: The projectile trajectory is corrected by a combined optical and electronic system on board the projectile. The projectile travels within the electromagnetic fields of the launcher and the field is generated by a sensor corrected by the fire director system. Projectile deviation from required trajectory is fed into computer operating trajectory correction beam. The projectile guidance and tracking system ensures reliable correction. The projection (10) has a launcher with a position sensor. The polarisation system rotating with the projectile produces a reflection for determining the instantaneous rolling position. The polarisation filter on the launcher is rotated synchronously with the rotation of the polarisation system in the projectile. The rolling position sensor receives only a certain constant proportion of energy radiated by the projectile equipment.

Patent DE-2836941-A1 (DE)
Inventor: GOERN WALTER
IPC: B29C48/09
Filed: 1978-08-24
Abstract: Hollow extruded sections are cooled externally as they emerge from the extruder; the interior of the sections is gas-cooled, using a gas which is under pressure at the nozzle and flows out through the sections to their ends at atmospheric pressure. The extruded sections are conventionally cooled externally by water jets. Compressed gas is passed to the bores and out through the interior of the extrusions. The gas expansion cools the inside walls of the extrusions, the degree of cooling achieved depending upon its pressure drop, its volume, and the medium used. The gas does not affect the temp. of the extruder nozzle but provides extra cooling effect on the extrusions, air can be used.
