Title: Double tuned single coil sampling head for NMR measurements - allows transmission line to be shortened if capacitors are includes in lower end of inner conductor
Inventor: ZEIGER HEINZ DR ING
IPC: G01R33/36
Filed: 1990-01-25
Abstract: The RF sample coil is tuned by circuit elements to operate with a high freq. input and over a wide range lower freq. input to permit double resonance experiments. A transmission line on the high freq. side of the coil is open circuit at the far end and has a length, for example lambda/2, which is a multiple of 1/4 of the high freq. wavelength so that it does not affect the input. At the upper end of the low freq. range the line acts capacitatively. At the midpoint of the lambda/2 line is a jumper with interruptor. When the latter is closed the line acts inductively and enables the lwer end of the low freq. range to be used. The line is physically shortened if capacitors are included in the lower end of the inner conductor, and the input is coupling loop acting at the centre of the line 42. ADVNATAGAE - Broad freq. range.

Title: Drinks prodn. using dosing vessels to measure liq. components - where the quantity of second component is added to dosing vessel of first component to reduce problem of e.g. high viscosity
Inventor: METTE MANFRED DR ING
IPC: B01F3/08
Filed: 1990-12-05
Abstract: In making drinks from at least two components, each component is measured in a separate dosing vessel before the components are mixed. A quantity of a second component is placed in the dosing vessel of at least one first component, and the quantity of the first component which is necessary to give the required proportional mixt. is then added to this dosing vessel. The quantity of the second component which is placed in the dosing vessel is measured, and the quantity of the first component to be added is determined by this measurement and by the quantity of the second component which is held in its own dosing vessel. In the making of a drink from water and syrup, the first component would be the syrup and the second the water. USE/ADVANTAGE - Used in preparing drinks from two or more liq. components. The addn. of the second component (e.g. water) to the dosing vessel of the first component (e.g. syrup) enables mixing of the syrup to commence in the dosing vessel and reduces problems arising from the higher viscosity and stickiness of the syrup, such as possible blockages of the outlet pipes. Residual quantities of the first component can also be put to use, since the quantity of the second component is adjusted to suit the available quantity of the first component.
