IPC: G06F12/16
Filed: 1979-10-12
Abstract: This storage is either integrated with a main memory or arranged separated from it, each addressable control storage location being associated with an integrity bit which is set to "1" for each control storage location to be protected during the initialisation phase and is set to "0" for each storage location not to be protected, or conversely, the integrity bit belonging to each control storage location being removed when the location is addressed. The write gate circuits prevent writing into the control storage when the integrity bit indicates that this is a protected storage location. An attempt at overwriting a protected storage location is also signalled to a repetition circuit which allows a predetermined number of repetitions. The overwriting attempt signal generated is used as trigger for error correction and for safeguarding and identifying faulty instructions. <IMAGE>

Patent EP-0045874-A1 (EP)
Inventor: HOLLAND-LETZ GUENTER
IPC: B41F31/02
Filed: 1981-07-20
Abstract: Means for inking printing elements (3) in a printing zone (2) on the surface of a printing roller (1). The means contains an ink roller (7) and a transfer roller (12) which is arranged between the surface of the printing roller and the ink roller and transfers the printing ink from the ink roller to the printing elements when the surface of the transfer roller rolls on the surfaces of the printing roller and the ink roller. The printing roller and the transfer roller engage by means of a positive drive connection. This makes it possible even for line code printing elements, in which slipping of the printing roller relative to the transfer roller can easily occur, to be uniformly and strongly inked since the positive drive connection prevents slipping.   <IMAGE>

Abstract: The pedal effort required to change the setting of a governor (13) of an engine increases sharply with increased engine speed. Booster controls have been provided in the art for applying a boost force (F B ), additive to an operator input force (F L ), for opposing the force (Fs) of a governor spring (42), thus to reduce pedal effort at high engine speeds. The improved booster control (15) herein includes an actuating chamber (53), and a control arrangement (51) for controlling fluid pressure in the chamber (53) when the setting of the governor (13) is changed by the operator and in a predetermined ratio to the operator's input force. The booster control (15) has wider application wherein a boosting force (F B ) is desired to supplement an input force (F L ) for controlling movement of a member (23) having a opposing force (Fs) applied thereto.
