Title: Furniture lid with spring loaded hinge - has toggle lever with spring parallel to toggle arm
Inventor: WOLFRAM NORBERT
IPC: E05F1/10
Filed: 1973-11-06
Abstract: The furniture fitting acts as a spring loaded element which secures the lid in open or closed position. The hinge mechanism has a spring which acts as an energy storage element and the locking effect is achieved by exceeding the dead centre position. The mechanism is highly compact and its length depends only on the linkage itself and not on the length of the spring required. This mechanism is fully concealed within the furniture. The toggle lever with the spring is mounted by a pivot on the rotaing member of the actuating lever which accommodates the spring and an end stop. The rotating bearing is held on the furniture wall and the pivot for the spring loaded toggle arm is held eccentrically in this support bearing. The spring is compressed on actuation and it prevents inadvertent closing of the lid. On closing the movement passes over a dead centre position and hence the lid is firmly held in the closed position.

Title: Multi-speed gearbox using two parallel gear shafts - involves successive constant axial movement of one shaft to provide gear changes
Inventor: FICKENSCHER HANS
IPC: F16H3/22
Filed: 1974-06-06
Abstract: A multi speed gear box provides successive gear changes by incremental gear shifts in a single linear direction of movement. An input shaft (1) and an output shaft (2) are located parallel to each other at a fixed distance. Gears are carried on each shaft and are sized to give progressively varying ratios. Each gear is of a fixed thickness (d) and the spacing of gears on one shaft is four times this (4d) and the spacing on the other five times (5d). In the neutral position the first gear ratio requires a linear shift of one shaft through a distance equal to the thickness of one gear (d). A further shift of the same distance disengages first gear and causes meshing between the second pair. Successive shifts by the same amoun t provides the higher ratios.

Title: Surface sealing metal coated plastics - using a metal sealing layer applied by galvanising process
Inventor: PUETZ ALBAN
IPC: C23C4/08
Filed: 1975-01-08
Abstract: Parent patent disclosed a method of applying >=1 metal layers upon the surface of a plastics article by spraying molten metal(s) upon it. Specifically, the surface of the plastics article is first coated with an adhesive layer which is allowed to harden after which molten Zn is sprayed on, at ca. 1000 degrees C and under pressure, to re-soften the adhesive so taht it becomes sticky again and also forms, together with the Zn, a mixed layer. After cooling and hardening of this mixed layer >=1 further Zn-layer is applied, as binder layer(s), and when that is cooled some other metal, esp. Cu melt is sprayed on whereupon the so-completed metallising is provided with a liq.-proof sealing layer. The novel aspect of this patent is that the sealing layer is a metal which is deposited upon the sprayed-on metal layers by a galvanising process. Sealing of the metal layers by galvanising with another metal has proved to provide better liq.-proofing than sealing with plastics (e.g. "Plexiglass" ETM), as in parent patent. Also, the metal-galvanising is considerably more impact-resistant than the prior art plastics sealing coating. Suitable for decorative and protective treatment uses e.g. workpieces etc.
