Title: Typewriter
IPC: B41J29/26
Filed: 1979-05-02
Abstract: An electronic typewriter can erase a character and an underscore in response to an error correction command. When an underscore command is entered, a memory which stores the code representing the characters typed is altered in its content to indicate upon the reading of that code that the character has been underscored and that the underscore must be erased as well as the character. The apparatus accomplishes multiple erase cycles to remove the underscore and then the character. In proportional space mode of operation, multiple underscore erase cycles are possible to remove an underscore which is wider than the underscore type font on the type element. <IMAGE>

Title: Improvements in or relating to flame monitors
IPC: F23N5/20
Filed: 1979-08-23
Abstract: This invention relates to a flame monitor which has a sensing circuit 11 with a flame sensor 10 and a sensing relay 13 which switches a sensing switch 5 which is connected in parallel with a bridging switch 4 connected to a supply line 1. With one contact, sensing switch 5 controls a fuel valve 7 and with the other contact a circuit 16 with two alternatively energized relays, a bridging relay 24 and a relay 27 for switching the flame loss simulation and a timing device 30. The bridging switch 4 switches the fuel valve 7 and a safety circuit 3 with a safety relay 22 for switching a safety switch 2 located in the supply line and a parallel connected second timing device 31. During operation the first timing device 30 is discharged, causing the bridging switch 4 to provide parallel energization of the fuel valve 7 and then the flame loss simulation is actuated by relay 27 so that sensing switch 5 switches power to circuit 16 and timing device 30 is charged. Relay 13 then removes the flame loss simulation from the flame sensing circuit 11, so that sensing switch 5 again energizes fuel valve 7, while bridging switch 4 switches safety circuit 3. The cycle then starts again. <IMAGE>

Title: Analog electronic timepiece
IPC: G04G5/00
Filed: 1979-10-02
Abstract: An analog electronic timepiece comprises an oscillator circuit (1) which produces a standard time signal. A frequency divider circuit (2) frequency divides the standard time signal.

Title: Method of and arrangement for deriving characteristic values from a sound signal
IPC: G10L15/00
Filed: 1980-09-24
Abstract: In order to reduce the information contents of a sound signal, for example a speech signal, the sound signal is divided into adjacent frequency ranges and the signals then obtained are consecutively integrated over short time intervals to short-time-spectrum signals. Subsequently, a histogram of the short-time-spectrum signals is formed for each frequency range and said histograms are divided into a given number of equal-area portions. The boundaries of said portions, which are referred to as quantiles, represent the characteristic values. The amplifier noise or the noise of the complete recording arrangement as well as a difference in sound energy level during when different sound signals are processed can then be eliminated at least in respect of their effect.
