Title: Cartridge plunger conserving contents - has flexible forward wall and projection fitting part way into nozzle for complete discharging
Inventor: MANEN DICK T VAN
IPC: B65D83/00
Filed: 1977-05-02
Abstract: A cartridge plunger has a flexible forward wall with a forwardly extending central projection shaped to fit part way into the nozzle. The flexible forward wall is moved to a rearward position when the plunger engages the contents of the cartridge as it is inserted in the rear end of the cartridge. Although the forward-extending projection displaces some of the contents the volume made available around the projection from the forward wall in the rearward position is greater than the volume displaced by the projection. This allows a slight increase in the total volume of contents loadable into the cartridge. When the plunger is forced against the front of the cartridge, the contents are not only forced out of the cartridge itself, but also from a portion of the nozzle occupied by the forward projection of the plunger.

Title: Housing for ball or roller bearing - containing radially acting spring to maintain adequate fit between race and housing
Inventor: BUREK WOLFGANG
IPC: H02K5/173
Filed: 1978-11-04
Abstract: To inhibit loss of fit between the bearing outer race (15) and the bore of the bearing housing (13) a spring strip (16) is inserted which exerts a uniformly radial force between the two components. The spring compensates for changes in fit due to differential thermal expansion between the housing (13), normally of aluminium, and the bearing (12). It also damps any tendency for the race to hammer inside the housing due to vibration of the machine. The spring strip is typically contained in a groove (17) in the bearing housing. The strip may have ridges at regular intervals running parallel to the shaft axis. The application is principally to ball and roller bearings used in dynamos for motor vehicles where there is considerable vibration and a large temp. change in operation.
