The number of components needed to make the tool are reduced and reliability improved. The heat-resisting plastic has good anti-friction properties which assist the movement of the pistons in the cylinder.
Patent DE-2355160-A1 (DE)
Title: Translation readiness setting method - is for only one of the two translations at the ends of a data transmission line
Inventor: PLAUE GUENTER
IPC: H04L5/16
Filed: 1973-11-05
Abstract: Each translation has a signal sender and a signal receiver. Sending request signals are exchanged between translations during transmission breaks. This signal received by a translation sets its sending readiness, and if the translation has signals ready for sending, it sends them. If not, it sends to the other translation the sending request and sets itself into readiness for reception. Reception of signals as a result of a sending request signal sets this translation into its sending readiness state. It sends an acknowledgement signal to the other translation. When these signals are retransmitted to evaluating devices, signals available for transmission, or a sending request signal are sent to the opposite translation.
