Title: Propeller drive for small fishing boat - engine charges battery for alternative electric drive without noise
Inventor: TRAUB FRANZ
IPC: F02B61/04
Filed: 1973-09-20
Abstract: A small fishing boat able to navigate shallower water and without noise which would disturb the fish, these being conditions which do not suit an outboard motor, has an accumulator driven electric drive unit which may be used as an alternative to an engine. The combined electric drive and charging unit is connected by a belt drive with the propeller drive shaft, and the motor is mounted on rails, so that by sliding the motor, a belt drive can be engaged or disengaged with the same drive shaft, and to charge the battery. The sliding movement of the motor can be reversed so that the belt drive is disengaged and a friction drive is engaged instead, so that the charging unit is disconnected while the propeller is driven. An adjustment system allows the propeller to be raised and lowered, and also swung sideways for steering.
Patent DE-2353928-A1 (DE)
Title: Reducing running-in time of steel components - by controlling depth of reduced hardness surface zones
Inventor: KAISER JOHANN
IPC: F16C33/14
Filed: 1973-10-27
Abstract: In a method of improving the sliding properties and reducing the running in time of steel components, subjected to wear, by reducing the hardness of the outermost surface layers of the hardened components to 700 Hv, the depth of the zones of reduced hardness is chosen as a function of the surface roughness of the components. Pref. this depth is half the roughness depth and is produced by decarburising before hardening, by vapour coating or by annealing after hardening. Used for treating new components of machines such as ring spinning machines. Running-in times can be reduced to a few hours and, after running-in, cavities still remain for retaining lubricant so that lubricant films exist even at high loads.

Title: Switchable short cct windings for shaded pole motor - has two diagonal windings with only one short circuited at any time
Inventor: HERRMANN ARTUR
IPC: H02K17/10
Filed: 1974-04-13
Abstract: The switchable short circuit windings for a bidirectional shaded pole motor has two windings lying opposite to one another not just in one, but in two, diagonal directions on the outer magnetic circuit close to the rotor. The diagonal windings are not continuously short circuited. The short circuit is selected to be between the winding in one diagonal or the winding in the other diagonal. This arrangement of windings allows the shaded pole motor to be driven in two directions and thereby avoids the needs for two shaded pole motors coupled to the same shaft to perform functions that require the shaft to rotate in both directions.

Title: Collapsible retainer ring for low drag ski stick - has spoked plastic discs with compression spring collapsing element
IPC: A63C11/24
Filed: 1974-04-24
Abstract: The retaining disc at the lower end of a ski stick is replaced by a collapsible structure which is made from two star shaped plastic discs.

Title: Corrosion resistant composite coating - formed on steel substrate by series of electroplating steps followed by heat treatment
Inventor: KATSUMA KUNIO
IPC: C25D5/10
Filed: 1974-05-30
Abstract: Corrosion resistant composite coating is formed on steel by first electroplating the steel with zinc, then electroplating a layer of copper over the zinc, then electroplating a layer of tin over the copper. The composite layer structure is heat treated to obtain an alloy layer between the inter. copper layer and the outer tin layer. The heat treatment is carried out in a gaseous phase or in an oil layer at temp. around the melting point of tin so that the actual temp. of the outer layer does not exceed the melting point of tin. Excellent corrosion resistant properties can be obtained and the plating layer is uniform.
