Abstract: ABSTRACT CODED INFORMATION ARRANGEMENT . An active transponder device comprises a CMOS integrated circuit including means for receiving an input signal including coded information, a memory for storing said information, and transmitter means for transmitting an output signal including said information, the input signal and the output signal being both low frequency induction communication signals.       Normally, the output signal is emitted in response to an interrogation signal received via the receiving means and is formed by modulation of that signal with said information after readout from the memory.  The transponder operates inherently synchronously, using a single master clock signal which is generated either  in an interrogation transmitter or in the programmer for injecting the coded information. The integrated circuit has a second receiving means used in the injection of the coded information.  The injection of a clock-pulse which is in synchronism with the input signal enables  the memory  to receive the coded information. The transponder may be used for the identification of e.g. people or articles at the limit of particular area e.g. a  store.

Abstract: ABSTRACT In a multi- stago absorbtion refrigeration system which uses water as a refrigerant and a saline solution such an Lithium Bromide as an absorbent, it is well known in the prior art that varios pumps are needed to circulate the refrigerant and the absorbent solution throughout the system.              This invention deals with a system of "reverse re-frigeration", or in other words a heat pump; and is not con-cerned with removing heat from a building and throwing it away into the atmosphere, but in collecting free heat from any sourse such as Solar Energy, Heat from waste water,Heat collected from refrigerated spaces and re-used, heat from waste air ejected from a building, etc.etc.        The novelty of this system also rest in the fact that it is unique in requiring no pumps or compressors to circulate the refrigerant or the absorbant solution as will be seen in the following specifications.         It is also claimed by the inventor that this system is unique in that it provides Heat and Cold at the same time without having to reverse the flow of the system. of the above mentioned sources of energy are collected stored in holding reservoirs of both hot and chilled water for later use as domestic hot water and for both heating in winter and cooling in summer.

Abstract: Abstract The present invention discloses a self-purging centrifuge  (10)  having  a  drum  (11)  mounted within  a housing (30) for rotation about a generally vertical axis. A driven rotor assembly is coaxially mounted within the drum (11).  The rotor assembly includes a number of trun-cated,  cone  discs  (22,  24,  25)  nested together,  with adjacent disc surfaces spaced apart.  Each disc, excluding the bottommost disc (25), has portions with apertures (23) therein.  The apertures  (23) are aligned to allow light liquid flow through the disc assembly during the separa-tion process.  Contaminated fluid is introduced into the drum  (11)  below the bottommost disc  (25)  of the rotor assembly.  The rotating rotor assembly propels the fluid outwardly  toward a  side  wall  (12)  of the drum  (11). Paddle members (28) mounted on a rotor head shaft (27) and fins (26) extending downwardly from the underside of the bottommost disc  (25)  further accelerate and propel the contaminated fluid towards the drum side wall (12).  As the drum (11) rotates the solid particles collect on the drum side wall  (12).  The heavier liquid and the light liquid separate  and  flow upward.  Extension means  (50) guide the clarified heavier liquid from the drum (11) into the heavier  liquid openings  (52)  in the drum top wall member  (13).   An  annular baffle member  (45)  extending downwardly from the drum top wall member (13) guides the clarified light liquid  flow overflowing from the rotor assembly upward into the clarified light liquid openings (46) in the drum top wall member (13).  Separate collec-tion chambers  (48,  53) are provided between the housing (30) and the drum exterior for the clarified liquids, each with an outlet (49, 54) for releasing the liquids from the centrifuge  (10).   During  the purge cycle,  carryover of solids  and contaminated  fluid into the liquid openings (46, 52) is prevented by an extension means (50) mounted to the drum top wall member  (13) between the clarified heavier liquid openings (52) and the drum side wall (12).     An annular baffle (60) extending inwardly from the bottom of the  drum side wall  (12)  provides  drainage  for the contaminated fluid and resuspended particles during the purge cycle.
