Title: Door key not probe to fall out of lock - has centre of gravity removed from key bit angle setting
Inventor: WALTHER DIETER
IPC: E05B11/00
Filed: 1980-06-10
Abstract: Danger of falling out of a lock is prevented by a special arrangement of weight distribution in a key for any type of door, esp. where it takes up a sloping setting if the door is shaken. The centre of gravity is not set in the same angular setting as the key bit. The centre of gravity is far enough from the axis of rotation for effective rotary momentum to be achieved. The result is that vibration causes the key to rotate away from the angular setting at which it can be put in the lock or removed from it.

Patent DE-3138670-A1 (DE)
Title: Steam treatment
Inventor: SINGELMANN DIETRICH E DIPL ING
IPC: F01K19/04
Filed: 1981-09-29
Abstract: This patent application relates to a "steam treatment" which makes the major part of the low-pressure turbine installation plus condensation of a power station plane superfluous; in other words, the "large parts" of a turbine and downstream condenser with a corresponding waste heat loss are saved. The steam working in the turbine is bled from a stage of medium pressure or low pressure and compressed with water injection in a "wet" turbocompressor, so that the steam under the pressure of fresh steam and having a dryness of x = 1 or x < 1 flows from the compressor directly into the superheater, from where it starts a new circulation. The water required in the wet turbocompressor is taken from a low-pressure turbine, greatly reduced in size, plus downstream condenser. Detailed circulation calculations provide the basis for a comparison: heat consumption with steam treatment and heat consumption in a normal power station with full condenser and full vaporisation. The construction of the "wet" turbocompressor is then discussed. See attached Figure 20. Application of the invention in new power stations, in power stations which are to be extended cheaply, and in rail or road vehicles. See also application of addition P 3,217,486.1. Further applications of addition are in preparation. <IMAGE>
