Abstract: ABSTRACT A building is provided with a solar heating system both for heating the interior of the building and providing hot water for use in the building. A solar collector is mounted on the roof and an antifreeze solution is cir-culated through the solar collector, space heaters in various rooms and a heat exchanger in the hot water tank. Heat collected by the antifreeze solution in the solar collector is given up to the space heaters and to the hot water tank. Antifreeze solution is easier to heat than fresh water and is unlikely to freeze causing pipe breakages, a problem exhibited by previous systems.

Abstract: Abstract A power line fault detector (10) includes a capacitive impedance (12) and another impedance (14) connected in series between the hot and ground conductors of the power line, with a trigger circuit (16) being connected between the neutral conductor of the power line and the junction of the impedances.  The impedances have values selected such that the voltage at the junction thereof with respect to the neutral conductor does not exceed a preselected limit unless the power line is faultily connected.  The trigger circuit normally has a high impedance but switches to a low impedance when the voltage across it exceeds the preselected limit, then producing a surge of capacitive impedance charging current.  A sensing circuit (20, 21, 26) senses the surges of current in the trigger circuit and provides an indication to the operator that the power line is faulted.

Abstract: ABSTRACT OF THE DISCLOSURE          A system for monitoring an abnormality of an oil-filled electric device by detecting the compo-nents of the gas staying dissolved in the insulating oil in said oil-filled electric device is constituted from a gas-in-oil separator which separates the gas from the insulating oil in an oil-filled electric device, a gas reservoir where the separated gas is collected, an air feeder which supplies air for delivering out the gas in said gas reservoir, a separating column packed with a gas separating filler whereby the gas supplied from the gas reservoir is separated into the components, a gas detector unit comprising a combustible gas detector element disposed in a case which connects at its one end to the outlet of said separating column and opens at its other end into the atmosphere, and a change-over valve disposed at a location connecting said gas reservoir, said air feeder and said separating column and adapted to switch a route passing the air from the air feeder into the separating column along with the gas via the gas reservoir to or from a route passing the air directly into the separating column.  This system is capable of easily detecting the components in the gas in the insulating oil to allow monitoring of an abnormality with high reliability.  Also, according to the system of this invention, at least the components CH4 and H2 in the separated gas are measured separately, and in case it is judged that an abnormality is present, the type of such abnormality is judged from the ratio of said components.

Abstract: Abstract:     A plug door for a vehicle such as a railway carriage, is carried and driven by a swinging lever which has a slid-ing fulcrum mechanism the effect of which is to flatten the arc through which the door is carried.  The edge of the door which trails in an opening movement is guided either by means of a relatively long pivot arm or by a curved or straight track. The alternative guide means give different trajectories to the leading edge of the door, and all require much less room than known swinging plug doors.  The long pivot arm guide keeps the door closest to the side of the vehicle during opening.  A du-plicate swinging lever with sliding fulcrum mechanism as a guide for the trailing edge will move the door parallel to the side of the vehicle and the sliding fulcrums will substantially reduce the outward excursion.          By mounting the driving swinging lever over-centre, i.e. closer to the trailing edge of the door the plug action is provided for so that a closed door may be flush with the vehicle.

Abstract: LOCKUP CONTROL SYSTEM TORQUE CONVERTER         ABSTRACT OF THE DISCLOSURE      A control circuit is disclosed for automatic lockup of a torque converter in the driveline of a work vehicle.  The primary control for engaging the lockup clutch is a speed signal corresponding to the speed of the output shaft of the torque converter.  A speed responsive signal generating means produces a lockup signal at a first set point when the torque demand is at a higher value and has a lower speed set point for producing a lockup signal when the torque demand is at a lower value.  A transmission responsive signal generating means produces and enabling signal for torque converter lockup when the transmission is in forward drive above the first speed range.  Shift of the transmission from one drive range to another produces a momentary disenabling signal to cause the lockup clutch to be disengaged and minimize driveline shock.  Overspeed signal generating means produces a disenabling signal to cause disengagement of the lockup clutch in an overspeed condition. ]
