Patent DE-2804721-A1 (DE)
Inventor: TANIMOTO AKIRA
IPC: G10L19/00
Filed: 1978-02-03
Abstract: A synthetic speech calculator is provided which is capable of generating an audible sound signal which can be representative of keyed data, sequences of keyed data (and errors), processed data, the contents of a memory or the contents of a counter. The sound signal can be suppressed under certain specific circumstances or made soft in intensity. A synthetic-speech calculator includes the keyboard consisting of digit keys and function keys, a desired number of registers for storing information entered by the depression of selected ones of the digit keys, a read-only-memory for storing a large number of digital codes as sound quantizing information, counter means for specifying the address of the memory so as to take a specific digital code out of the memory, a digital-to-analog converter for converting the specific digital code taken out of the memory into an audible sound signal, and a loud speaker driven by the audible sound signal and producing an audible sound. There are provided means responsive to combinations of at least two sequentially operated keys of the keyboard for modifying the output condition of the audible sound, for example, volume, speed, etc. The synthetic speech calculator also has a selection key and multi-function keys, such as 7/sin theta . If the selection key is depressed followed by actuation of one of the multi-function keys, as audible sound indicative of the second function of the multi-function key is audibly generated, i.e., "sin theta " is audibly generated. If the selection key is not depressed prior to actuation of the multi-function key, an audibly sound indicative of the first function (7) is audibly generated. Similarly, the calculator will also develop an audible sound indicative of "EQUAL" if the following key sequence is actuated: axb=, where a and b are numerals. The calculator will develop an audible sound indicative of "TWO" if the following key sequence is actuated: ax=. An audible sound indicative of "THREE" will be developed if the following key sequence is actuated: ax==.

Title: Plastic foil joints - for high tensile stresses by press buttons with specified parameters
Inventor: MEIER PAUL
IPC: B31B50/68
Filed: 1979-07-28
Abstract: The joints of large sheets of plastic foil must often withstand high tensile forces, for example when they are used in coal mines to protect the roof of longwall coalfaces and have to be extended as the coalface advances. This aim is achieved by using press buttons with a backing plate of rectangular shape with a length of at least four times and a width of at least twice the hole dia. The length of the stud is such that it ensures a close fit of the two selvedges when it has snapped into the recessed socket. This provides a reliable joint for high tensile stresses under dusty and wet conditions.

Title: Automobile automatic transmission responsive to passenger load - allows higher ratios for low chassis load for higher economy
Inventor: GRUBER GERHARD ING GRAD
IPC: F16H59/52
Filed: 1979-12-22
Abstract: The transmission has a number of discrete transmission ratios between which it is switched in dependence on the velocity and the carried load. The latter is detected by a device comprising a sensor (58), a load switch (60), a holding circuit (62) and an electromagnetic setting element (64), to allow the transmission to be switched to a higher or a lower gear than that which would normally correspond to the vehicle velocity, or to allow or prevent an additional transmission ratio from being brought into use. The transmission allows greater flexibility to accord with the actual passenger load, so that the vehicle is not held in an unnecessarily low gear, to give better fuel economy.
