Title: Double keel for water craft - consists of two keels at an angle to each other
Inventor: JAEGER JOHANNES
IPC: B63B41/00
Filed: 1974-11-20
Abstract: The double keel is for sailing - and motor yachts of all sizes, and has an A-shape, the two keels being at an angle of 10 - 90 deg. to each other. The keel ends carry rudders, to correct the angled position of the ship. Both keels have runners, to ease transportation and inspection. A movable fin is positioned between the two keels. With a tail wind, the fin raises the ship slightly, and thereby reduces water resistance. The double keel may be folded via rods.

Title: Miniature relay contact springs set - has moving leaf whose free end has cutout for switching position adjustment
Inventor: LUECK JUERGEN DIPL ING
IPC: H01H1/50
Filed: 1975-02-01
Abstract: The apparatus is designed to ensure significant reduction of bounce both during the attraction and the release of the armature. There is a contact leaf spring (1) which is clamped at one end at (6). The small size of the relay makes it expedient to place the actuator (7) outside the contact area of the leaf spring. Contact bounce is limited with a cutout at the free end of the spring in order to match the spring rate to the force-stroke characteristic of the relay electromagnet. The method is suitable for relays with relatively large strokes and low pull force.

Patent DE-2513623-A1 (DE)
Inventor: BODET PIERRE
IPC: G01D7/00
Filed: 1975-03-27
Abstract: Automatic indicia changer, such as a clock-calendar for displaying months, days of the month, days of the week, hours and minutes, comprises a plurality of series of plates bearing the various indicia, each series being rotatable about its axis under the influence of a ratchet wheel that is moved stepwise by a dog, each step changing the indicia one increment. The dog is swung by a lever which in turn is swung by a rotary cam. The first series of indicia is driven by a motor; while the first series drives the second and the second drives the third, and so on. Thanks to the ratchet wheel and pawl drive, each series of indicia can be manually adjusted without interrupting the automatic drive. Manual adjustment may be effected either rapidly, by turning the ratchet wheel with an external knob, or stepwise by pressing with the finger on a protrusion on the associated swingable lever.

Title: Automatic adjuster for electromagnetic friction clutch or brake - has compensation rings between flange hub and abutment
Inventor: BAUSCH EDMUND
IPC: F16D65/52
Filed: 1975-04-16
Abstract: An automatic adjuster is for electromagnetically operated friction clutches or brakes, with an axially fixed magnet section, and an anchor section, each forming a coupling or brake section. Compensation rings (8, 9) are positioned between the abutment (10) and a flange hub (5), which is fastened to a shaft (3) directly or via a hub (4), can move axially, and forced in a direction towards the abutment. The contacting front faces of the compensation rings have engaging multiple diagonal profiles. One ring is secured against rotation while the other one is turned by a spring (24), when a pressure release of the rings is caused, due to wear occurring between the magnet section and an anchor disc (6), which is larger than the nominal air gap adjusted by an adjuster. The anchor disc is fastened to the hub so that it will not rotate but can move axially.
