Abstract: JET DRIVE APPARATUS WITH NON-STEERING JET            REVERSE DEFLECTOR               Abstract of the Disclosure In a jet drive for a boat, a jet pump is secured to the boat transom and terminates in a pivotally mounted steering deflector for lateral movement of the jet. The deflector is mounted on a vertical steering axis within a gimbal ring which is pivotally mounted on a horizontal trim pivot means secured to the pump housing.  A trim linkage is connected to position the gimbal ring for trimming of the nozzle.  A reversing gate is pivotally mounted on the same trim pivot means and connected by a mechanical coupling linkage with swivel and pivoting joints to the gimbal ring. The linkage includes a shift shaft which is rotatable about an axis perpendicular to the pivot axis and which is axially movable with movement of the gimbal ring.  The inner end of the shaft is square and slidably mounted in a square opening in a rotatable input lever.  Rotation of the lever rotates the shaft and actuates the coupling linkage to pivot and place the gate in a preset drive or shift position.  The trim linkage causes trim movement of the ring which through the coupling linkage correspondingly directly positions the gate and with the shaft sliding in the input lever to hold the preset shift position with changes in trim.  The shaft is rotatably mounted in a rotatable steering tube and extends outwardly from the opposite ends.  The outer end of the tube includes a flexible tube with a shaft seal and bearing sup-porting the shaft and permitting limited flexing of the shaft within the tube during trim pivoting of the gimbal ring.

Abstract: ABSTRACT OF THE DISCLOSURE     A system enabling automatic identification of a hand written signature is provided.  A specimen signature is written with a special pen which will provide as output, signals representing the direction which that pen is moved to produce that signature.  This information is converted into direction per unit of time which is stored at a parti-cular address in the memory of a data processing machine.          For verification of such a signature, an individual indicates to the machine, in any suitable manner, the address where his signature is stored in memory, and then proceeds to write his signature again with said pen.  The direction per unit of time information which is generated at this time, is compared with the direction per unit of time read out of memory.  If there is sufficient correlation, the machine indicates the signature is acceptable.  If not, it indicates the signature is not acceptable.

Abstract: ABSTRACT         A system for recovering the waste heat normally exhausted into the atmosphere by chemical or other processing plants.  The system comprises a substantially self-contained apparatus for coupling to an exhaust stack and an inlet air plenum for furnaces so as to extract the waste heat from the exhaust gas for delivery to the inlet air.  The system may include temperature and pressure controls which enhance the safety and efficiency of the system's operation, and further may include flow control in a multiple burner installation so that the desired fuel air ratios and heat distribution may be achieved.          While the primary control is generally determined by a lower temperature limit for the exhaust gas below which condensation may occur, over-temperature and other controls are also provided.          By building the present invention as a substantially self-contained and self-supporting assembly, on site installation time and the required alteration and reinforcing of pre-existing on site equipment may be minimized, thereby affecting substan-tially economic savings by minimizing the resulting down time of the processing plant for installation.  Embodiments for a single burner nest heater, multiple nest cabins and grade level stack systems, as well as a specific embodiment of heat exchanger for use in the systems of the present invention, are disclosed.          The waste heat recovery apparatus comprises an exhaust gas duct having an inlet and an outlet for coupling to said furnace stack for carrying exhaust gas therethrough; a first heat exchanger means disposed within said exhaust gas duct for absorbing heat from the exhaust gas flowing through; at least one inlet air duct for coupling to said corresponding inlet air plenum of said furnace; and at least one second heat exchanger means disposed within said corresponding inlet air duct for heating the inlet air passing therethrough.  The inlet of said second heat exchanger is in communication with the outlet of said first heat exchanger and the outlet of said second heat exchanger is in communication with the inlet of said first heat exchanger through conduit means so as to define a flow circuit for a heat transfer fluid.  There is a reservoir in communica-tion with said flow circuit for maintaining a heat transfer fluid reserve; and pumping means for circulating a heat transfer fluid through said flow circuit.

Abstract: METHOD AND APPARATUS FOR MEASURING     ABSTRACT OF THE INVENTION             A method and apparatus for measuring the O2 content in an exhaust gas of an internal combustion engine by exposing two resistors to the exhaust gas of an internal combustion engine.  The resistance of both resistors varies as a functional of the temperature of the exhaust gas to which it is exposed.  However, the resistance of one of the resistors also varies as a function of the oxygen content of the exhaust gas.  Therefore, an electrical signal can be obtained which is a function of the O2 content of the exhaust gas, with the temperature effect of the exhaust gas on the resistor being minimized and/or eliminated.

Abstract: EPOXIDE RESIN-IMPREGNATED COMPOSITES     Abstract of the Disclosure A layer of a liquid composition containing an epoxide resin as the sole photopolymerisable component, a heat-activated curing agent for epoxide resins, and preferably a photopolymerisation catalyst, is exposed to actinic radiation until the layer solidifies to form an essentially solid, continuous film due to photopolymerisation of the epoxide resin through epoxide groups, the resin remaining, however, still thermosettable by virtue of residual epoxide groups.          The film so formed is contacted with fibrous reinforcing material and caused to flow about the fibers, suitably by applying heat and pressure, to form a prepreg. When desired, e.g., after the prepreg has been formed into some desired configuration or layers of prepreg have been stacked, the assembly may be cured by further heating.
