Patent ES-8202739-A1 (ES)
Title: Brake pressure modulating valve
IPC: B60T8/1766
Filed: 1980-12-12
Abstract: A vehicle brake system fluid modulating valve has a main piston acted upon by a control spring and master cylinder pressure on one hand and an opposing brake system on the other hand. A slave piston is also acted upon by the master cylinder pressure, and is arranged to control an operating point at which the main piston effects brake pressure modulation. This control is effected by cutting off the master cylinder pressure to the slave piston when the operating point is reached. Electrical transducers sense vehicle load and master cylinder pressure, respectively, and their output signals are processed by a comparator for consequential operation of the valve to cut-off the master cylinder pressure to the slave piston. The operating point is altered by balancing the master cylinder pressure signal in response to changes in the vehicle load signal.

Title: On-load isolating switch with a pivoting switch arm and with extinguishing means.
IPC: H01H33/40
Filed: 1982-03-18
Abstract: The pivotal switching arm of a "swivel post" type load break switch carries, in addition to a blade contact, a U-shaped sliding block type conducting driver which has an elongated elastically expandable slot that engages the ratchet head of the rectilinearly movable switch pin of a current quenching device mounted on the fixed contact post.

At the other end of the slot, an enlargement serves to release the ratchet head when the switch opens. The driver enables rectilinear quenching devices to be used in conjunction with the curvilinear motion of the switching arm.

Patent ES-8308182-A1 (ES)
Title: Subscribers loop synchronization
IPC: H04J3/06
Filed: 1982-05-13
Abstract: In a PCM system, it is desirable for the two ends to remain in synchronization, and for this purpose both channel associated and non-channel associated synchronizations are used. The PCM code combinations are eight bit codes, each with a ninth bit for sync and a tenth bit for data. When sync search is in progress, either at switch on or after sync has failed, the seventh and eighth bits of the PCM code bits are used to convey additional sync thus reducing the risk of simulation. To locate the sync, all other bits except the sixth and tenth bits are set to zero, the sixth and tenth bits being at one. Thus, two ones are separated by five zeros to form a pointer used to locate the sync pattern. The sync pattern is located by storing a data frame on reception and shifting it to find the combination of two ones separated by five zeros. The shift needed to find the combination indicates the extent of misalignment and is used to bring the receiver clock into alignment with the incoming bit streams.
