Abstract: ABSTRACT           A coffee making machine of the type adapted to be connected to a mains water supply is provided with a reservoir having a level sensor controlling the water refill valve to the reservoir,  and a heating element which is thermostatically controlled, the refill valve and the thermostat both being controlled by a single modular replaceable solid state circuit board.   The level sensor functions to cause refill of the reservoir to the appropriate level for subsequent brewing of a full pot of coffee,  irrespective of the mains water pressure and the route by which water may previously have  been  removed  from  the  reservoir.    The electronically controlled thermostat allows only small drops in temperature,  e.g.  3°F,  before operating to reheat the water in the reservoir.   The water can accordingly be stored at closer to the boiling point and delivered to contact coffee for brewing purposes at temperatures of not less than 200 F.

Abstract: ABSTRACT OF THE DISCLOSURE      In a method using a chromatographic separation apparatus consisting of plurality of unit packed beds each having a supply inlet/extraction outlet, wherein the apparatus is effectively divided into four zones; an adsorption zone, a refining zone, a desorption zone, and a concentration zone.  A supply and extrac-tion step is performed in which all of the fluid flowing out of the adsorption zone is extracted through the nonadsorbate fluid extraction outlet, and then a recycle step, in which no fluid is supplied to or extracted from the bed, is performed to move the concentration distributions in the bed to a desired position.          As a result, the method requires fewer unit beds, and enables extraction of components of higher purity.

Abstract: ABSTRACT         TRANSMISSION SYSTEM FOR SENDING TWO SIGNALS SIMULTANEOUSLY ON THE SAME COMMUNICATIONS CHANNEL A transmission system in which a suitably modulated speech or data signal is combined with a low bit rate (100b/s) spread spectrum signal and transmitted simultaneously on the same channel.     At a receiver the modulated speech or data signal is demodulated and the modulated speech or data signal together with the spread spectrum signal are applied to a multiplier in which the spread spectrum signal is despread.     A code synchronising signal may be included in the modulated signal prior to transmission and when recovered in the receiver, the synchronising signal is applied to a pseudo-random code generating means.  The transmission system may include a text transmission system in which case the low bit rate signal comprises pages of data.  A number of pages may be transmitted simultaneously by spreading the data associated with each page by orthogonal psuedo-random codes.

Title: Remote radiation dosimetry
Inventor: BRAUNLICH PETER F
IPC: G01T1/105
Filed: 1989-09-29
Granted: 1993-06-15
Abstract: Abstract Disclosed are methods and apparatus for remotely measuring radiation levels. Such are particularly useful for measuring relatively high levels or dosages of radiation being administered in radiation therapy. They are also useful for more general radiation level measurements where remote sensing from the remaining portions of the apparatus is desirable. The apparatus uses a beam generator, such as a laser beam, to provide a stimulating beam. The stimulating beam is preferably of wavelengths shorter than 6 microns, or more advantageously less than 2 microns. The stimulating beam is used to stimulate a remote luminescent sensor mounted in a probe which emits stored luminescent energy resulting from exposure of the sensor to ionizing radiation. The stimulating beam is communicated to the remote luminescent sensor via transmissive fiber which also preferably serves to return the emission from the luminescent sensor. The stimulating beam is advantageously split by a beam splitter to create a detector beam which is measured for power during a reading period during which the luminescent phosphor is read. The detected power is preferably used to control the beam generator to thus produce desired beam power during the reading period. The luminescent emission from the remote sensor is communicated to a suitable emission detector, preferably after filtering or other selective treatment to better isolate the luminescent emission.
