    摘要： A DIRECTION INDICATOR SYSTEM FOR A TRACTOR-TRAILER VEHICLE INCLUDES A SWITCH ON THE TRACTOR FOR ENERGISING THE TRACTOR LAMPS BY WAY OF A CIRCUIT INCLUDING FIRST AND SECOND FLASHER UNITS, THE FIRST FLASHER UNIT ONLY BEING OPERATIVE WHEN THE TRACTOR LAMPS ALONE ARE ENERGISED BECAUSE THE CURRENT FLOW THROUGH THE SECOND FLASHER UNIT IS INSUFFICIENT TO ENERGISE IT. WHEN THE TRAILER IS COUPLED THE FIRST FLASHER UNIT IS SHORT-CIRCUITED AND THE SECOND FLASHER UNIT ALONE OPERATES.

    摘要： An electromagnetic horn comprises a casing, a resilient diaphragm closing the casing, an electromagnet carried by the casing, an armature associated with the electromagnet and secured to the diaphragm and a movable contact within the casing. The movable contact is movable into or out of engagement with the fixed contact by the armature to control energisation of the electromagnet and a bolt extends through the casing and is connected to the fixed contact so that rotation of the bolt relative to the fixed contact adjusts the position of the fixed contact relative to the casing. The head of the bolt is accessible from the exterior of the casing and is engaged in a restraining member which is secured to the casing so as to be immovable relative to the casing in a direction parallel to the axis of the bolt. The restraining member holds the bolt against axial movement relative to the casing but permits angular movement of the bolt relative to the casing.

    摘要： A liquid level indicator system for indicating the level of a conductive liquid in a reservoir includes a probe, at least a portion of the probe which is immersed in the liquid when the liquid level is at or above a predetermined level being coated with a layer of material which is absorbent to the conductive liquid so that a true indication of the liquid level in the reservoir is obtained.

    摘要： A thermally operable switch including a vane which is movable between a stable position and an unstable position in response to thermal expansion and contraction of a part associated with the vane. Contacts operable in response to said movement of the vane, and lagging associated with said part, the lagging increasing the cooling time of said part, and thereby increasing the time interval between consecutive operations of the contacts.

    摘要： A DIRECTION INDICATOR SYSTEM FOR A TRACTOR-TRAILER VEHICLE HAS A DIRECTION INDICATOR SWITCH ON THE TRACTOR THROUGH WHICH THE LAMPS ON THE TRACTOR CAN BE ENERGISED AND A SUPPLY TERMINAL ON THE TRACTOR. FIRST AND SECOND FLASHER UNITS ARE CONNECTED IN SERIES BETWEEN THE SUPPLY TERMINAL AND THE MOVABLE CONTACT OF THE DIRECTION INDICATOR SWITCH, AND AN ELECTRICAL CONNECTOR ON THE TRACTOR IS PROVIDED FOR ENGAGEMENT WITH A COMPLEMENTARY CONNECTOR ON A TRAILER, THESE CONNECTORS WHEN ENGAGED CONNECTING THE FLASHER LAMPS AT OPPOSITE SIDES OF THE TRAILER IN PARALLEL WITH THE FLASHER LAMPS AT OPPOSITE SIDES OF THE TRACTOR RESPECTIVELY. A TWO POSITION SWITCH IS USED WHICH IN ONE POSITION SHORT-CIRCUITS THE FIRST FLASHER UNIT AND IN ITS OTHER POSITION SHORT-CIRCUITS THE SECOND FLASHER UNIT, SO THAT THE CORRECT FLASHER UNIT IS ALWAYS USED DEPENDING ON WHETHER THE TRAILER VEHICLE IS IN OPERATION, OR NOT.
