Title: Under water massage system incorporated in bath shell - has own pumping system and nozzle ejectors set into bath shell wall
Inventor: D ANGELO ROCCO
IPC: A61H33/00
Filed: 1974-04-11
Abstract: An underwater massage system consists of a bath shell with a series of openings with interchangeable nozzles. The openings are connected by a channel system which is linked to a pump whose take off lead is attached to the interior of the bath. The channel system is formed from two outer rings soldered or welded to the bath shell and sealed by an external plate and gasket retained by screws.

Title: Domestic pasta maker with hand or motorised drive - has rotating scraper for dividing up dough
Inventor: HILLER PAUL
IPC: A47J43/20
Filed: 1974-05-25
Abstract: The pasta maker comprises a funnel (1) hich is filled with dough whereupon a roller (3) is rotated clockwise by a crank handle (4) so that the dough is passed through a gap in the funnel (1) to the scraper which rotates anti-clockwise. Since the scraper (2) rotates faster than the roller (3) the dough is scraper off from the roller and can fall directly into the frying pan producing Swabain dumpings which cannot be distinguished from those prepared by hand. The rotating scraper can be provided with straight cutting edges which is particularly suitable if the machine is operated by hand but helical blades can be used which is preferable if the machine is motor driven.

Title: Household refuse compactor - refuse container lift and vertically adjustable ram reduce space requirement
Inventor: JUNG KARL
IPC: B30B9/30
Filed: 1974-10-10
Abstract: The container with refuse is stepwise lifted by depressing pedal operated against a torsion spring so that the bottom surface shifts a roller together with gripper whose slot is controlled by a guide bar in the housing of the lift gear. The bore of the gripper is slack for the lift rod, and the gripper is under the influence of a spring, while another spring and brake washer control it from the top. This ensures that depression of the pedal results in the lift of the refuse container by the arm welded to the housing. The container is then pressed by the plate of the ram and the operation can be repeated for the ultimate height reduction of the refuse.
