Patent CA-1263634-C (CA)
Title: Liquid level detector apparatus for a concentrate dispenser tank
Inventor: SCHROEDER ALFRED A
IPC: B67D7/08
Filed: 1985-02-04
Granted: 1989-12-05
Abstract: ABSTRACT OF THE INVENTION A liquid concentrate dispensing apparatus having a removable and refillable concentrate tank with sensors connected therewith flush with the inside wall of the tank to facilitate cleaning. The sensors comprise detectors which include an electrically conductive housing, and one wall of the housing is substantially flush with the inside wall of the tank. Spring biased detent members on the outside of the tank releasably connect the detectors with the dispensing apparatus when the tank is inserted to a preselected position. The tank is provided with two such sensors, one is located in the sidewall and the other is located in the bottom wall. When the tank is inserted into the dispensing apparatus, the spring biased detent members engage contacts on the apparatus. A current passes between the detectors on the sidewall and bottom wall when both are covered by liquid concentrate. When concentrate no longer covers the detector in the sidewall, the current doesn't pass, thus indicating that concentrate needs to be added to the tank.

Title: Laser-excitation fluorescence detection electrokinetic separation

IPC: G01N27/447
Filed: 1986-09-17
Granted: 1992-10-20
Abstract: LASER-EXCITATION FLUORESCENCE DETECTION         ELECTROKINETIC SEPARATION            Abstract of the Invention An  electrokinetic  process  and  apparatus  employing coherent  radiation-excited  fluorescence  for  detection  is disclosed.      Specifically,   the   detection   of   electro-kinetically-transported target species as said species pass in a support electrolyte through a detection volume can be carried out with improved efficiency when the detection event associated  with  the  passage  of  the  species  through  the detection volume is a change in emitted light, in particular fluorescence,  which emitted light has been generated by a beam  of  electromagnetic  radiation supplied on-column by a coherent  source.    The  use  of  coherent  radiation  source permits  the  radiation  of  a  well-defined  wavelength to be delivered on-column to the sample without hazard and without appreciable   loss   of   intensity   and   without   unwanted interference from scattered light, as compared to incoherent light  sources.    The  use  of  coherent  radiation  increases sensitivity  because  interference  from  Raman  and  Rayleigh scattering  is  minimized.    This  detection  system  allows mixtures of compounds to be analyzed and/or separation with improved efficiency.   It  is possible,  using the detection system of this invention, to detect amount of targets in the range of a femtomole (10-15 moles) or less.

Abstract: ABSTRACT     Printing Mechanism A printing mechanism is described having a plurality of type carriers (12, 34) which at their outer peripheral face carry in one region printing types and in another region indicator types (44).  The printing types can be brought by turning the type carriers (12, 34) into a printing position. The turning travel of the type carriers (12, 34) can be limited with the aid of stop means (100, 102, 104, 106, 110). By means of a setting means (32, 20, 24) which can be brought by axial displacement into a drive connection with each of the type carriers (12, 34) each type carrier (12, 34) can be turned.  A torque limiting means (96) permits transfer of a limited torque between a first component (32) and a second component (20) of the setting means.  A securing means (68, 72) serves for axially fixed connection of the first component (32) to the second component (20).  The torque limiting means is formed by resilient detent elements (96) which are disposed on the first component (32) and which are in engagement with complementary detent elements (66) on the second component (20).  The securing means (68, 72) is disposed on the second component (20).            Fig. 1

Abstract: A CERAMIC MONOLITHIC STRUCTURE HAVING AN INTERNAL CAVITY   CONTAINED THEREIN AND A METHOD OF PREPARING THE SAME            ABSTRACT:     A method of preparing ceramic monolithic structures with an internal cavity and passageways is described.   A thin sheet of a ceramic material is formed by spreading the material on a glass plate with a doctor blade. Individual sheets of the material are cut or punched to form predetermined holes,  channels or various shapes therein.  These individual sheets are then stacked to form a layered structure.  A supporting media such as paraffin wax is injected into the holes and channels to completely fill them with the media.  The layered structure is then pressed by unipressing and/or isostatic pressing followed by a prefiring step to remove the supporting media.  Once the supporting media had been completely removed,  the layered structure is then sintered to form a monolithic structure containing precise predetermined internal cavity and passageways.
