Patent MX-9703207-A (MX)
Title: Signal processing unit for a trolley pole switch controller.
Inventor: LAUNIER FRANCIS
IPC: B60M1/14
Filed: 1997-04-30
Abstract: A signal processing unit for a controller of a trolley pole switch is disclosed. The trolley pole switch switches the path of travel that an energy collector takes through the switch at a junction of catenaries at which a turn catenary and a straight catenary diverge from the straight catenary. The signal processing unit includes an input stage, a detection stage, turn and straight signal modulation stages and an output stage. The input stage conditions modulated signals, each of which indicating a request to switch the path of travel through the trolley pole switch to the desired catenary diversing therefrom. The detection stage generates a validation signal if the conditioned modulated stage receives a conditioned modulated turn signal from the input stage and the validation signal from the detection stage simultaneously, it generates a low logic signal. If the straight demodulation stage receives a conditioned modulated straight signal from the input stage and the validation signal from the detection stage simultaneously, it generates a low logic signal. If a low logic signal is received from the turn modulation stage, the output stage energizes a turn relay thereby supplying power to a turn solenoid for switching the path of travel to the turn catenary. If a low logic signal is received from the straight demodulation stage, the output stage energizes a straight relay thereby supplying powr to a straight solenoid for switching the path of travel to the straight catenary.

Title: Form of constructing multi-sided concrete wall - using wedge dividing form wall side into two sections to strip form from cast concrete
IPC: E04G11/08
Filed: 1985-02-12
Abstract: An inner form set-up (1) and an outer form set-up (2) are formed of a series of form panels. The form set-ups are stripped from the cast concrete without disassembling form panels for ease of resetting them in another location for the next moulding. For stripping the inner form set-up which has a multisided form wall from the cast concrete, at least one wedge divides at least one side of the form wall into two portions. This is wedged in between the two portions in a first direction during casing. The wedge is movable in a second direction opposite to the first after casting. The two portions are brought to be nearer relative to one another. The inner form set-up contracts and therefore is spaced apart from the cast concrete.
