Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a process for the preparation of phenols which comprises reacting an .alpha.-hydroxyalkyl-substituted aromatic compound and/or an .alpha.,.beta.-unsatur-sted alkyl-substituted aromatic compound with hydrogen peroxide in the presence of an acid catalyst, in which hydrogen peroxide is diluted with a diluent, es-pecially acetone, so that the volume is at least 10 times the original volume, and the diluted hydrogen peroxide is supplied in a divided manner to at least two portions of a reaction vessel or the diluted hydrogen peroxide is scattered by sprinkling the same into the reaction vessel.  According to a preferred em-bodiment, the diluted hydrogen peroxide is continuously supplied to the gas phase in the reaction vessel from a scattering device which is similar to but separate from a scattering device for supplying the starting aromatic compound, particularly, a product formed by oxidizing an isopropyl aromatic compound with molecular oxygen.  According to this process, the efficiency of utilization of hydrogen peroxide is increased and a phenol of high quality can be obtained in a high yield with a high safety.

Abstract: EMERGENCY LOCATOR TRANSMITTER INCIDENT TIME CORRELATOR     ABSTRACT:      In an emergency locator transmitter of a type wherein a standard distress signal is transmitted following a distress incident, the distress signal is encoded with data identifying the absolute time of the incident or the amount of time that has elapsed since the incident occurred.  Distress waveform modu-lation of the carrier is periodically interrupted for insertion of the time signal.  In a preferred embodiment, wherein the distress signal includes information burst signals that are periodically transmitted, e.g., every 50 seconds, timing pulses generated synchronously with the burst signals are supplied to a divider circuit for division by a predetermined integer to develop extended time base pulses, e.g., one hour pulse intervals.  The extended pulses are accumulated in a binary counter and combined with the information burst signals.

Abstract: ABSTRACT OF THE DISCLOSURE           A fireplace insert is disclosed which will efficiently heat the interior of a structure, enable control of fuel burn rate and temperature of heated air directed into the interior structure, and facilitate circulation of the heated air through the interior rooms of the structure via the pressure differential created by the forced-air flow through the insert.  The unit includes an air-tight cover to the interior fireplace opening, a continuous heat exchanger across the top of the fireplace combustion chamber which continues down parallel to the rear of the fireplace combustion chamber and opens rearward to the outside air dual intake chamber which is equipped with a variable speed fan.  The interior end of said heat exchanger mates with the forced air outlet in the air-tight cover to the fireplace opening.  Said outside air dual intake chamber is equipped with a screen on the end opening to the outside of the structure, a butterfly damper between the fan and an intake shield adjacent to the fireplace combustion chamber, said shield having an air flow passage extending along the lower face of the combustion chamber and air flow exhaust into the front of the combustion chamber. The variable speed fan, which control the volume of air passing through the system, draws outside air and passes it under pressure into the dual chambers.  The upper chamber leads to the heat exchanger unit and the lower chamber opens to the air flow passage under the combustion chamber.  The butterfly valve, in the lower chamber, controls the burn rate of the fuel in the combustion chamber of the fireplace.  This process yields a positive air pressure in the interior room created by the heated air, so that the warm air will pass freely into rooms adjacent to the one in which the fireplace is located.

A photon emission source is provided at one end of the (Nd:YAG) rod embodying a diode and a parabolic reflector system associated with a polarized mirror which is partly reflective and which in part transmits energy rays.  A polarized optical mirror is provided at the opposite end of the (Nd:YAG) rod.  Activation of atoms within the rod is initiated within the contents of an optical or resonate cavity providing a means by which the necessary excitation of atoms within the optical active (Nd:YAG) rod can be achieved in order to initiate an elevation in population and subsequent inversion of levels, near and over the threshold value necessary to generate a laser beam and the subsequent discharge of said beam.  Heat dissipating means are provided including nylon phenolic quartz acrylic compound constructed to have a heat transfer gradient.          Embedded in the compound is heat transfer means provided by longitudinally positioned microcoil heat pipes whereby the heat is transferred to the rear of the device.  At the rear is positioned a heat dissipating cube formed by parallel plates with microcoil heat pipes between them.  The evolution of heat is initiated by the transference of heat from the microcoiled heat pipes to the nylon phenolic quartz compound, which subsequently vaporizes as heat is absorbed by the compound, the vapor being released at various portal exits or microvents aft of the laser device.

A hydraulic cylinder has the top end of its piston connected to the upper lifting arm, and the bottom end of its fluid cylinder connected to the bottom end of the lift-ing rod, and a valve is included in the line between the hydraulic fluid reservoir and the fluid cylinder.  The valve controls relative movement of the hinge block and the lifting rod to thereby control relative movement of the hinge block and the upper arm under the action of gravity and a hoisting means.          The apparatus is adaptable to semi-automatic, automatic or remote control operation.  In one of the embodiments, the lift-ing arrangement consists of an upper lifting arm which is dis-posed above the hinge block and extends laterally thereof.  In a second embodiment, the lifting arrangement comprises vertically extending bars which are disposed on either side of the hinge block and which are attached to each other at both ends thereof.
