Abstract: ABSTRACT OF THE DISCLOSURE          Water or air from sanitary drains, clothes dryers and the like having a temperature above the temperature of cold water normally entering the hot water tank, is directed through a heat exchanger which includes a coil connected bet-ween the source of cold water and the hot water tank.  If connected to waste from a sanitary drain or the like, a tem-perature sensing valve is provided to divert drain water be-low a pre-determined temperature.  In both cases, a water storage tank is provided into which the tempered water passes from the heat exchanger and this tank is situated above the heat exchanger.  An inlet line extends from the heat exchanger to the storage tank and a circulating line extends from the storage tank to the cold water inlet line leading to the heat exchanger.  A one-way valve is situated in this circulating line so that even if water is not being drawn from storage tank, circulation of the water from the storage tank through the heat exchanger, and back, is assured by convection.

Abstract: ABSTRACT OF THE DISCLOSURE       A multisection crane boom having a fly and jib assembly attachable thereto is disclosed herein.  The fly section and jib section of the assembly are pivotally interconnected at adjacent ends through a freely pivoted link so that the jib section can be pivoted from the position extending generally parallel and below the fly section to a usable position where-in the longitudinal axes of the two sections are aligned with each other or coincident at the interconnected ends.  Cable means are utilized for holding the jib section in an extended position on the fly section and the cable means are capable of having the jib in end-to-end or angular relation with respect to the fly section.  The fly section also has a lug thereon which prevents attachment of the cable means when the fly sec-tion is at an angular position with respect to the main boom.

Abstract: ABSTRACT OF THE DISCLOSURE      An electrical testing instrument including an amplifier circuit having a pair of inputs, one com-prising a probe and the other being adapted for manual engagement by the user for completing an input circuit through the body of the user.  The circuit has a bat-tery and a current-responsive indicator in its output circuit to provide a signal when current flows in the input circuit to provide a critical forward biasing of the amplifier.  The battery is connected to furnish such input current when the input terminals are con-nected in a closed circuit having a resistance of at least approximately the resistance of the user's body.          The amplifier circuit is further arranged that when the probe is contacted with a live AC power line and the manually engageable input terminal is so manually engaged, an operating indicating current will also be present in the output circuit.

Abstract: ABSTRACT           Apparatus for stabilizing output characteristicss of an injection laser by monitoring the output level of the laser corresponding to the d.c. bias level and maintaining this level constant at a value which corresponds substantially to the laser being biased at or very close to threshold.  The apparatus has a light sensitive device for producing an electrical signal corresponding to the d.c. bias level of the laser.  The electrical signal is compared with a reference signal to produce a further signal which is applied to d.c. bias control means for the laser.          The d.c. bias control means responds to the further signal to adjust the d.c. bias level such that the d.c. light output level remains substantially at a predetermined level.  The mean or peak output of the laser can be controlled in a similar manner.
