Patent DE-2331858-A1 (DE)
Title: Vacuum cct. breaker with stationary and moving contacts - has two relatively movable magnetic cores for driving moving contact
Inventor: LATTEYER GERT
IPC: H01H36/00
Filed: 1973-06-22
Abstract: The moving contact drive consists of two relatively movable magnetic cores whose magnetic field is changed by their mutual displacement. A metal plate may be provided at the moving contact end away from the breaking point, which is attracted in the rest position by the magnetic drive, thus opening the breaking point. The moving contact is biased by a spring in the closing direction of the breaking point. The magnetic cores may consist of laminated sheet metal. One stationary magnetic core may have an aperture across the laminations, engaged by the moving magnetic core. The drive may be separated from the breaking point by a partition, through which penetrates the moving contact in vacuum-tight manner.

Title: Broadband damper for mechanical oscillations of suspended cables - has piston damper linked to two brackets clamped apart along line
Inventor: HOECKELE MAX
IPC: H02G7/14
Filed: 1973-07-10
Abstract: The broadband mechanical damper, for suspended lines or tubes, prevents oscillations in the line by using a piston damper to act against changes in the distance between two clamps attached to the line. Brackets are slung below the clamps and are connected by a rod pivoted to one bracket at one end and pivoted to a lever at the other end. The lever is pivoted to the second bracket and its free end is linked to the damper piston. Oscillations cause the rod to move and tilt the lever. The damper resistance is transmitted back through the lever and rod to the first bracket. The damper is particularly effective at low vibration frequencies.

Title: Circular air filter element - having folded paper medium with inner and outer seals moulded on
Inventor: OBERNOSTERER GERHARD
IPC: B01D46/00
Filed: 1973-08-21
Abstract: Air filter for carburretors on petrol engines is shaped so that the intake is via the centre and this has seal, as has the outer edge. The filter is formed in two stages. The paper element is first crimped, formed into a ring and the ends glued together. The outer seal is then moulded onto the ends. This is then turned to push the unsealed end to the centre and the moulding forms outer edge. The crimps in the centre are then tightly sealed so that when a plastic seal is moulded on, no material leaks up the crimps causing loss of area. The element is then complete. The inner and outer edges can be used to seal on the housing. These can be assymetric with the paper and seals can be formed on edges as well. The filter is more compact.

Title: Coffee grinder with inclined motor-driven mechanism - has gap between lid and grinder wall bridged by support forming passage for ground coffee at one point
IPC: A47J42/40
Filed: 1974-04-17
Abstract: The kitchen grinder is provided with a collecting container which adjoins the grinder housing and is provided with a perforated lid which is spring biased in the direction of the vertical operative position of the grinder wherein the dividing gap between the lid of the container on one side and the opposing grinder wall on the other is bridged by a multi-point, preferably three point support for the lid by projections which engage on the apparatus and are designed to positively engage in opposite socket to transfer the force. One of these support points forms the passage for the ground coffee between the outlet and the opening in the grinder housing and lid. In this way the ground coffee is transferred without any danger of contaminating the components, nor does it reside too long in the grinder where it would become warm and lose its flavour.
