Abstract: ABSTRACT OF THE DISCLOSURE            A disposable reaction container composed of rigid or semi-rigid material which comprises, preferably in one piece, spaced apart side walls of substantial lateral extent, a bottom wall and two end walls, there being two chambers in the container separated from each other by dividing means that is contiguous with said side walls and that is impervious except for a passage of restricted cross sections through said dividing means in the lower portion of the container and at least one of said chambers having windows therein adapted and arranged for the transmission of light therethrough and through a body of given thickness of liquid between said windows. The chamber is accessible from the top for respectively receiving aqueous liquid and at least a portion of the passage between the chambers is located sub-stantially above the bottoms of the respective chambers so as thereby to form pockets into which the aqueous liquid may be received into each chamber and lyophilized without becoming commingled with liquid in the other chamber when the reaction container is in upright position.  Preferably the portion of the passage that is above the bottom of each chamber is above the openings of the passage respectively into each chamber with at least one and preferably both of said openings adjacent the chamber bottom.  In one embodiment the configuration of the passage is defined by a portion of the dividing means that is up-standing from the bottom wall in combination with an upper portion.          A method is disclosed whereby the aqueous liquids in each chamber are kept separated from each other by a body of air entrapped in the passage between the two chambers and aqueous solutions are introduced into each chamber, lyophilized and reconstituted with water prior to forcing solution from one of the chambers through the passage into the other chamber.

Abstract: ABSTRACT OF THE DISCLOSURE Formation of nitrogen oxides and/or soot is obviated by mixing recycled combustion gas with incoming comburant supplied to a burner via a distribution opening and controlling the mass flow rate of combustion gas being recycled with respect to the mass flow rate necessary for the gaseous comburant, the mixture being passed to the burner as a turbulent flow in which the ratio between the kinetic momentum flux of the mixture and the product of the radius of the said distribution opening times the axial movement quantity flux of the mixture has a value at least sufficient so that the said turbulent flow produces a recirculation of the said mixture within the said chamber in the form of a toroidal vortex.  This is achieved by apparatus comprising a mixing enclosure having two inlets each provided with means for regulating the size of its aperture, and an outlet, the inlet communicating respectively with the atmosphere and with a duct for combustion gases, the outlet being connected to the inlet of a ventilator whose outlet communicates with gas mixture supply means arranged coaxially to a fuel injection nozzle in order to impart a turbulent motion to gas mixture emitted from the supply means.

Abstract: DEVICE FOR CONTROLLING BOAT SPEED            Abstract of the Disclosure Relates to attachments to a motor boat for reducing the speed of the boat below the idling speed sufficient to permit trolling for fish.  The speed con-trolling device includes a plate member mounted for movement from a vertical position immediately aft of the propeller and across the path of the propeller wash, thereby to slow the speed of the boat to a second position away from the propeller and out of the path of the pro-peller wash.  Hydraulic mechanism including a piston-cylinder combination unit is connected to a fixed support, such as the propulsion unit of the boat, and to the plate member for moving the latter between the aforesaid two positions of movement.  Ports are provided in the cylinder for admitting fluid under pressure to either side of the piston to impart movement of the piston in either direc-tion in the cylinder and to impart corresponding movement to the plate member.  A rotary hydraulic pump is driven by a reversible electric motor to provide not only the source of fluid pressure for moving the piston and plate member but also the port in the cylinder into which the fluid pressure is introduced for determining the direction of movement of the piston.  A three-position electric switch is provided for controlling the operation of the electric motor either in one or the other of its two directions of rotation or for rendering the motor inoperative.

Abstract: DIGITAL FLOW PRESSURE REGULATOR Abstract of the Invention A high pressure fluid source is connected to a primary orifice and a valved orifice of a binarily activated pressure regulator.  The primary orifice alone supplies the fluid at a pressure below the minimum desired, and both orifices together supply the fluid at a pressure greater than the maximum desired. A sensor at the output is adjusted to open the binary valve when the minimum pressure is reached, and close the valve when the maximum pressure is reached, thus cycling between the two conditions.

Abstract: Abstract of the Disclosure Color encoding format for a color picture infor-mation record, and recording apparatus therefor, are disclosed for recording of discs for use with both (1) disc players designed to provide PAL-type outputs for driving PAL type color television receivers, and (2) disc players designed to provide SECAM-type outputs for driving SECAM-type color television receivers.  In players, up-con-version of recovered composite signal precedes comb filtering to separate luminance and chrominance components.  Decoding of up-converted chrominance component, to obtain base-band color-difference signal information is followed by remodulation of a carrier pursuant to a desired output format.  Comb filter arrangements of U.S. Patent No. 3,969,757 are used when up-conversion shifts color subcarrier to a frequency in vicinity of PAL subcarrier frequency, but bearing odd integral multiple relationship to half the line frequency.  Differing comb filter arrangements are employed when up-conversion shifts color subcarrier to PAL subcarrier frequency.  Demodulation/remodulation arrange-ment involving the separate detection and remodulation use of two color-difference signals, as well as system requiring detection and remodulation use of only one color-difference signal, are disclosed.

Abstract: METHOD AND APPARATUS FOR CONTROLLING A PROGRAMMABLE LOGIC ARRAY            Abstract of the Disclosure A circuit is described for controlling a programm-able logic array adapted for use with a communications terminal.  The logic array includes an input AND-section defined by a plurality of addressable fields and an output OR-section.  One field of the input section is addressed by an incoming address register selectively loaded with incoming data.  A second field is addressed by a branch address register loaded with selective outputs of the output section thus providing program branching capabilities.  Also, a loop counter and a clocked program counter address two additional fields of the input section.  The loop counter facilitates program looping in the logic array while the program counter affords real time operational characteristics for the control circuit.
