Patent DE-2333817-A1 (DE)
Title: Carpet sweeper with self-cleaning rotary brushes - includes cleaning comb with tooth gaps related to tooth widths
Inventor: HUKUBA HIROSHI
IPC: A47L11/33
Filed: 1973-07-03
Abstract: The carpet sweeper has a cleaning comb which strips the dirt and dust from the rotating brushes and the width of the gap between each tooth of the comb is a multiple of the width of an individual tooth. At the bottom of each gap is a small projection whose point slides along the peripheral surface of the rotating brush and when the tips of the teeth engage deep in the rotating brushes the bottom of the gap just touches the peripheral surface of same. The small projections thus clean the surface dirt of the brushes whilst the teeth penetrate down to remove the remaining dirt and dust. The resistance between the rotating brush and cleaning comb is slight so that the mobility of the carpet sweeper is not impaired.

Patent DE-2346092-A1 (DE)
Title: Self sharpening saw or milling cutter - has teeth made from relatively soft material which is surface hardened for regenerating cutting edge on wearing
Inventor: ETTELT BERNHARD PROF DIPL ING
IPC: C21D9/24
Filed: 1973-09-13
Abstract: The saw or milling cutter does not require resharpening during its whole life as it is designed to wear into a sharp cutting edge. The basic material is surface hardened pref. by enrichment with borch, and on profile grinding the front of the tooth is ground away and the soft metal is exposed. The tooth front is subject to relatively greater wear than the tooth cutting faces, which then project further forward when the softer core material is worn away. Hence the geometry of the tooth can be designed arbitrarily. In the case of saws, the conventional geometry of the carbide tipped saws can be used. The hardness of the surface layer can be much higher than on using carbides. Since the tooth core is made of soft material there is no danger of fracturing.

Title: Permanent-magnet-operated valve - has casing sliding over disc enclosing magnet to reverse direction of field
Inventor: MELNIKOWA ALEKSANDRA ALEKSANDR
IPC: F16K31/08
Filed: 1973-12-01
Abstract: An armature works in a non-magnetic sleeve, and carries a shut-off component at one end, while at the other the flux of a permanent magnet acts upon it, the sleeve passing through the field concerned. The permanent magnet (9) is mounted between two discs (7, 8) of soft magnetic material, solidly fixed to the sleeve (5). These are enclosed in a casing (10) of soft magnetic material, and this slides axially in relation to them as the armature moves from one end position to the other, thus reversing the direction of the field of the permanent magnet. The result is that the magnetic circuit remains closed in both end positions, allowing a smaller magnet and valve to be used.
