Patent DE-2310311-A1 (DE)
Inventor: MORIMOTO YOSHIRO
IPC: B60K20/02
Filed: 1973-03-01
Abstract: To prevent erroneous or accidental movement of a gear-shift lever to a position effecting shifting into reverse in a manually operated automotive power transmission system, the gear-shift lever is rotatable about its axis and urged to turn about the axis to a predetermined angular position in which the gear-shift lever is prevented from being moved to a position effecting the shifting into reverse even though the lever has been moved to a position selecting the reverse gear. The reverse gear is moved to an operative position only when the gear-shift lever is rotated about its axis from the predetermined angular position and further moved to a position moving the reverse gear to the operative position.

Title: Rocket launching tube of variable length - barrel length regulated by solid axially moving piston
Inventor: MALLENER WERNER
IPC: F41A27/24
Filed: 1973-06-06
Abstract: The launching acceleration of the rocket depends on the pressure build-up within the barrel. The longer the barrel the greater the inital acceleration of the rocket. The barrel of variable length is used to control the range of the rocket travel. The piston and barrel system is mounted on an elevating and rotating base. The reaction force on launching from a solid barrel is accommodated by the foundations via the solid piston or trunnion pins. The piston can be moved within the barrel by a rack arrangement or by a rope and pulley arrangement. The barrel may also have gas escape holes. These holes are covered or openend by the appropriate mechanism.

Title: Self-sticking mains conduit - uses protection band covered adhesive layer on one broadside of tape conduit
Inventor: WIESER HORST
IPC: H01B7/08
Filed: 1973-09-14
Abstract: The mains tape conduit has, at least on one broadside, a self sticking adhesive layer which is, until use, covered by a removable protection band.

Title: Elastomer sleeve coupling seal - composite seal has soft centre section which deforms under pressure to provide sealing
Inventor: WAIBLINGER FRIEDRICH
IPC: F16L21/03
Filed: 1973-12-22
Abstract: A composite elastomer seal consists of three main section sof varying hardness. The centre ring section of the seal is much softer than the outer sections. The seal locates in a recessed groove and the middle section is compressed between the bore of the outer sleeve and the shaft. On either side of the central bore of the sleeve are two grooves. When fluid pressure is applied from the central bore via a gap the harder material of the seal outer sections cause the softer inner section to expand. The inner section then fills the grooves and provides a leak proof seal.
