Title: Car cleaning brush with rotating middle part - has two water spun rotary brushes rotating in opposite directions
Inventor: STARKERT HERMANN
IPC: A46B13/06
Filed: 1976-12-11
Abstract: The brush has a rotating middle part (1) which consists of two water wheels with paddle ends. A water hose is screwed to the brush handle, so that the water is conducted through pipes and is then pressed through nozzles (4, 4a) as a result of the strong water pressure. The nozzles are arranged obliquely opposite to produce rotation of the water wheels in opposite directions. A partition (6) in the middle of the brushes is impervious to water, and serves to support the two water wheel brushes. The contrary rotation of the two water wheels causes the water to come out through all holes, thereby wetting all the bristles (14, 17). The outer edge of the water wheel paddles (15) is inside the brush casing, and only allows the bristles of the water wheel from the rigid brush part to rotate (17).

Title: Hinged or sliding fire door - has spacer which melts to allow vertical movement on supports to press door against seals
Inventor: GAIL JOSEF
IPC: E05C21/02
Filed: 1977-01-19
Abstract: The fire-proof door (101) is hinged to the frame (111), the hinges (103, 107) permitting vertical movement of the door relative to the frame. The door is retained in its raised position by a third hinge (105, 109) with a thermoplastic spacer piece (113). In the event of fire, the thermoplastic component (113) melts, permitting the door to drop under its own weight. Downward movement of the door causes the catches (129) to engage with oblique surfaces (125) which are mounted on the frame (111). The resulting force, perpendicular to the plane of the door presses the door against smoke-proof seals. The principle may also be applied to a sliding door.
