Title: Digital storage of data sets - accommodates sets of any length and complexity by using final pointer as address identifier
Inventor: HOLTZ KLAUS
IPC: G06F17/30
Filed: 1978-03-09
Abstract: A method of storing information in a digital store of a computing system is designed to enable each input data set, of any length and complexity, to be identified by the last address location corresp. to it. A starting address is loaded into store, and a recognisable stop code placed in the corresp. storage location. The address is combined with the first data set character to generate a matrix which is then checked against having already been stored before being allowed into the next free storage location. If the matrix has already been stored the address is used to define the pointer which is combined with the next character to produce the next matrix. The procedure is repeated until the end of the data set, when the last pointer becomes the last address location.

Title: Safety socket with switching levers - ensures interruption of current in both conducting pins following withdrawal of plug
Inventor: THUERER HARRI
IPC: H01R13/703
Filed: 1979-05-11
Abstract: The safety socket has a pair of extending arms (2) which project into the plug (1) and are pivoted at the end inside the socket. These arms are pref. made of plastic or a similar material, and are bevelled at the ends which enter into grooves in the plug. The switching arms (2) can also be activated by the central spring (4) which would have the advantage that they would be concealed and be free from external interference. When a plug is inserted into the socket, the arm(s) (2) are pushed to the rear and thereby operate the On/Off switches. The reverse applies when the plug is withdrawn, the switches opening and breaking the current flow or voltage to the socket. Even when the conductors to the socket are reversed, a potentially dangerous situation is avoided on withdrawal of plug since both conductors are made safe.
