Patent DE-1943801-A1 (DE)
Title: Implanted object made of titanium or a titanium-based - alloy for bone surgery
Inventor: STEINEMANN DR S
IPC: D21H21/30
Filed: 1969-08-28
Abstract: Implanted object is covered with a surface layer of oxide, nitride, carbide or carbonitride. More specifically the surface layer can be coloured, manufactured by anodic treatment, at high temperature by reaction with gases or in a salt bath. Advantages: greater wear resistance than an implanted objected without surface coating, greater corrosion resistance against tissue fluids since the layers have no electrical conductivity, this applying not only to the larger surfaces but also to the particularly sensitive depressions and apertures such as screw holes and slots. Attacks by corrosion can be particularly readily located if the coating has an interference colour. Furthermore the provision of a coating prevents the formations of spots occurring due to handling.

Title: Rocket motor - with star-shaped division between quick and slow burning propellants
Inventor: ARRIBAT PAUL
IPC: F02K9/12
Filed: 1971-09-13
Abstract: As the quick-burning propellant in the centre is ignited it builds up a flame front which conforms to the internal shape of the star-shaped division, until it overcomes it and ignites the slow-burning propellant which continues the star-shaped flame front pattern, assisted by the external corrugations of the outer propellant which match the arms of the star formed by the division. The purpose is to provide a controlled burning and flame pattern to maintain the required gas stream for acceleration and propulsion under controlled conditions.

Title: Locking mechanism for box lids - consists of spring loaded pin with locking groove which engages with box edge
Inventor: LOMNICKY HEINZ
IPC: E05B63/24
Filed: 1973-09-27
Abstract: This closing element is used for covering plates which rest on the wall edges of the box or the container. This lock ensures that the cover is not shaken off by vibrations. The cover plate is readily locked and also released and it is pressed with constant pressure against the box edge. No additional guide pins are necessary. The cover plate is held on the housing wall. The cover plate has spring loaded guide pin with tapered end and with circumferential locking groove. The pin is guided in the housing in the cover plate. On fitting the pin enters the cylindrical socket in the housing wall. The tapered pin pushes aside the locking rib which forms an extension of the unlocking plate. The locking rib enters the locking groove in the pin. For releasing purposes, the unlocking plate is pressed against the force of the spring in the cut-out in the wall. The cylindrical pin guides and aligns the cover plate in correct alignment between the components.

Patent DE-2417178-A1 (DE)
Title: Maximum speed control for car - with automatic throttle control and external indicator of maximum set speed
Inventor: STACH HERBERT ING GRAD
IPC: B60Q1/54
Filed: 1974-04-09
Abstract: A pointer is moved over the speedometer dial to the selected maximum speed. A photocell monitor operates when the speedometer needle reaches the pointer and controls an electromagnetic valve to reduce the throttle setting. This throttle control can be bypassed if the accelerator pedal is pressed fully down, i.e. if the vehicle has to accelerate out of trouble. External indicators show the maximum selected speed so long as this is not exceeded. This enables highway patrols to monitor traffic speeds without elaborate radar equipment. A dashboard warning operates if the set speed is exceeded.
