Abstract: HEAT EXCHANGER OF THE TUBE AND PLATE TYPE                 ABSTRACT OF THE DISCLOSURE           A heat exchanger having an outer shell with an elongated, semi-circular fluid duct plate mounted in the shell.  A tube bundle slidable between the duct plate and the shell is fixed at one end relative to the shell.  The fluid inlet and outlet configuration, and transverse fluid flow pattern, are typical of those described in United States patent 3,532,160.  The exterior of the tube bundle is partially covered with a shrouding to contain the fluid flow within the tube bundle by allowing the fluid to exit only through the outlet side. Sealing mechanisms running longitudinally between the shrouding and the upper duct plate, and between the shrouding and the shell, provide a seal which restricts the fluid flow to a transverse flow through the tube bundle.  A seal between the supported end of the tube bundle and the shrouding confines the fluid flow in the bundle and allows for relative ex-pansion of the shrouding and the bundle.  Drains are pro-vided in the shell wall on each side of the lower sealing mechanism to allow for moisture run-off from the heat exchanger.

Abstract: AUTOMATIC STARTING FLUID DISPENSER      Abstract An automatic dispenser for injecting starting fluid into an internal combustion engine is disclosed.  This dispenser includes a valve actuator which is adapted to receive a valved canister containing a pressurized starting fluid and to pass starting fluid from the canister through a conduit to an injector positioned in an air intake passage of the engine.  The valve actuator is coupled to the starting system of the engine so that the canister valve is automatically actuated and starting fluid is continuously injected into the engine during operation of the engine's starter motor.  In this way a continuous flow of starting fluid is automatically dispensed during engine cranking.  The valve actuator is also provided with a reservoir which temporarily stores a predetermined volume of starting fluid while fluid is flowing through the actuator, and then supplies this fluid to the injector after the cranking has stopped, thereby providing starting fluid to the engine during the period immediately following termination of cranking.

Abstract: ABSTRACT       A method and apparatus in defibration of wood chips or similar vegetable material for conveying in steam pulp produced in a refiner (2) to a separator (7) for separating steam and pulp.          The separator is bounded against the atmosphere and is kept pressurized by steam, while a limited amount of excess steam is lad off. A flow of steam liberated from the pulp is taken from the separator and given an increased pressure for utilization in extracting pulp from the refiner. The steam flow is hereby led through the refiner and further to the separator, whereby the pulp is transferred to the separator by the steam which thus circulates to a considerable extent, said steam having been given the higher pressure either in the refiner itself, by means of pressure increasing means (19) therein, or upstream of the refiner in a separate pressure increasing means (11).

Abstract: ABSTRACT OF THE DISCLOSURE          PLURAL COMPONENT DISPENSING APPARATUS     A plural component dispensing system includes supplies which furnish first and second components under pressure to a dispensing apparatus having first and second valves, respectively.  Each of the valves includes a rota-table valve member in a combination retainer and seat.  The valves are connected to first and second pinion gears, re-spectively, and a rack engages each of the pinion gears.          The rack is attached to a piston which is disposed for reci-procation in a cylinder in response to fluid pressure on one side or the other of the piston.  Actuation of the piston in a first direction provides paths for component flow through the first and second rotatable valve members and through first and second orifices, respectively, into a mix-ing chamber.  The first and second orifices are disposed to provide impinging streams of the first and second components, the impingement insuring complete and thorough mixing of the components.  A nozzle is provided in the mixing chamber oppo-site the first and second orifices for dispensing the mixed components from the apparatus.  When fluid pressure is pro-vided on the other side of the piston, the first and second rotatable valve members are rotated to positions to block the flow of components into the mixing chamber.

Abstract: ABSTRACT OF THE DISCLOSURE:         To monitor a nuclear fuel element or fuel elements located in a store, e.g. a pond in a swimming pool reactor, the store is illuminated ultrasonically using one or more trans-ducers transmetting ultrasonic signals in one or more predetermined directions to obtain an output which, because it depends on the number and relative location of the fuel elements in the store, and the structure of the store itself is distinctive to the fuel elements or elements stored therein.  From this distinctive output is derived an identity unique to the stored fuel element or elements and a reference signal indicative of the whole structure when intact, the reference signal and identity being recorded.  Subsequent ultrasonic testing of the store and its contents under identical operating conditions produces a signal which is compared to the recorded reference signal and if different therefrom reveals the occurrence of tampering with the store and/or the fuel element or elements.
