Abstract: ABSTRACT OF THE DISCLOSURE     An extraction unit of the type having successively in the flow direction of the liquid, a mixer, a pre-settler and a settler, the pre-settler and the settler being separated from each other by several successive perforated partition walls, the perforations of each partition wall being laterally unaligned with the perforations of the following partition wall, the lower section of the mixer having inlets for the heavy phase and the light phase and a mechanical stirrer for mixing the heavy phase and the light phase to form a dispersion, and the upper section having at least one opening for directing the dispersion from the mixer to the pre-settler, the upper section of the settler having members for removing the separated light phase as an overflow from the settler, the lower section of which has an opening for the removal of the separated heavy phase from the settler as a controlled flow, and between the settler and the mixer there are pipes for returning part of the separated heavy and light phase from the settler to the lower section of the mixer.  The mixer is at least in part surrounded by the pre-settler and the openings for directing the dispersion from the mixer into the pre-settler are on those sides of the mixer which are facing away from the perforated partition walls between the pre-settler and the settler, in order to lengthen the path of the dispersion coming from the mixer and to divide it into two partial flows following each side of the mixer and to cause these flows to impinge against each other before reaching the said perforated partition walls, in order to damp the flow and to promote the separation of the phase.

Abstract: ABSTRACT OF DISCLOSURE         An electronic computer controls the operation of a communication system such as a citizen band (CB) radio. An electronic computer includes a program memory which stores the control sequence and code for an electronic lock.  The computer also includes a data memory for storing command and data signals from a keyboard through a set of input/output registers and intermediate results from computer computations. Other elements of the computer may be a timer, an accumulator and logic unit (ALU) and set of working registers.  A digital to analog converter converts an appropriate binary output from the computer into a voltage which is used as a reference for the communica-tion system power supply providing control for this device.  A second binary output from the computer provides for the control of the frequency signal channel over which the communications system is to transmit.

Granted: 1981-10-13
Abstract: ABSTRACT         This invention relates to solar energy collectors, and more especially to evacuated solar energy collectors comprising a housing forming a chamber.  The chamber has a transparent top member and bottom member which are joined together along the rims, thereby providing an airtight seal, the top and bottom members each having a surface convex to the outside whereby the chamber resists the external atmospheric pressure while having a relatively large absorber area to collector area ratio.  The bottom member of the collector can have a reflective surface to reflect the solar energy upon the underside of the heat absorbing unit, which is a spiralled tubular element retained within the collector.  Furthermore, a system of solar energy collectors can be constructed so that the top members of the chambers receive solar radiation during the day, and mirrors situated in the interstices between adjacent collectors direct solar energy to transparent lower surfaces of the collectors, the low profile of each chamber facilitating the architectural integration of the collectors in close-packed arrays.

Abstract: RCA 75,015 Abstract of the Disclosure A gain-controlled amplifier is provided which employs a controllable alternating-current resistance device.  The device is constructed in a similar manner as a vertical PNP transistor, having an emitter region of high conductivity P+ material, a P type collector region, and an intervening region of high resistivity (intrinsic) N type base material.  An N+ base contact region is separated from the P+ emitter region by an expanse of the intrinsic material which establishes a separation which is greater than the diffusion length of carriers injected into the intrinsic region.  The base emitter junction of the device which is formed by the N+ base contact region, the intrinsic region, and the P+ emitter region thus has the characteristics of a PIN diode, with a high injected carrier lifetime.  At higher signal frequencies, such as the frequencies of television I.F. signals, the base-emitter PIN junction ceases to act as a normal transistor rectifying junction, and becomes an A.C. resistance which varies as a function of the number of injected carriers.  Carriers are injected into the intrinsic region from the P+ emitter region, and vary as a function of the magnitude of the emitter-to-collector control current.  Only a very small base current component of the applied control current flows in the base-emitter junction, and therefore only this small base current component is applied to the amplifier which is coupled to the base of the device.  With the high carrier lifetime and operation at higher signal frequencies, the A.C. resistance of the base-emitter junction is virtually completely a function of the magnitude of the control current.
