Abstract: ABSTRACT OF THE DISCLOSURE           A water heater comprises an elongated vessel having a heat exchanger that occupies a substantial portion at one end and leaves a minimum volume storage and blending zone at the other end of the vessel.  Water is recirculated through the heat exchanger, preferably continuously, through a recirculation conduit that takes water through its inlet essentially solely from the outlet end of the heat exchange zone and returns it to the inlet end, the intake of the recirculation conduit being located very close to the end of the heat exchanger.  The temperature sensor of the control thermostat is received entirely within the recirculation conduit so that it is responsive to a high velocity flow of water drawn from the heat exchange zone.

Abstract: ABSTRACT OF THE DISCLOSURE:           An off-the-road type of vehicle which is adapted to travel on the rough terrain has a pair of frames distributed longitudinally of the vehicle, these frames, for example, forming a cab frame which is adapted to accommodate an operator of the vehicle and a load-carrying frame.  A pair of ground-engaging structures such as wheels are associated with the frames to support the latter for travelling movement.  A suspension connects one of the ground-engaging structures with the frame associated therewith, and this suspension includes an elastically yieldable structure to provide the possibility of elastic yield-ing movement in this suspension.  A joint structure interconnects the pair of frames so that they are turnable one with respect to the other at least about an axis which extends longitudinally of the vehicle in the direction of travel thereof and which is substantially horizontal when the vehicle is on substantially horizontal ground.  A second elastically yieldable structure is operatively connected with this joint structure to provide for elastic yielding resistance to turning of the frames one with respect to the other about the axis of the joint structure.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for stimulating body tissue is disclosed as including a circuit responsive to the initiation of stimulation, failure, or pending failure of a component of the stimulating apparatus, to provide the patient with a perceivable stimulation to a second, different portion of body tissue. An impedance level detector senses the impedance between the outputs of the stimulation apparatus to provide a warning signal indicating that the output impedance falls outside a predetermined range.  The impedance level detector output is sensed by a stimulation control logic to apply a first train of pulses at a first rate to an auxiliary electrode for stimulating the second portion of tissue.  A voltage level detector senses when the power source voltage depletes below a predetermined level, to actuate the stimulation control logic to provide a second train of warning pulses to the auxiliary electrode, at a second, different rate than that of the first train.  The patient is warned as to the pending failure or failure of a component of his pacemaker and is able to identify the failing component.  Also provided is decoder logic comprising a switch actuatable by a magnet that may be manipu-lated exterior of the patient's body to turn off the warning stimulation and/or to reset or reinitialize the operation of the stimulation control logic, so that the stimulation control logic is conditioned to receive further warning signals from either the voltage level detector and/or the impedance level de-tector.
