Patent DE-4006351-A1 (DE)
Title: Maintaining internal pressure in liq. chromatography column - and countering shrinkage by externally adjustable piston
Inventor: GROM EDGAR
IPC: G01N30/60
Filed: 1990-03-01
Abstract: The tendency of high pressure liq. chromatography column solids to shrink after a period, leaving gaps with a deleterious effect on subsequent sepn., is countered by application from the exterior of piston pressures which prevent dead vol. formation. Modified methods of applying such pressure include an adjustable piston applied to the piston by a threaded cap or flange. The piston seal is radially compressible from the exterior. The piston head can be applied to existing HPLC columns. ADVANTAGE - The columns may be initially completely filled and their service life is extended.

Title: Throughflow heater for tea or coffee making machine - has two temp. regulating switches both closed during brewing process
Inventor: WONKA BORIS
IPC: A47J31/54
Filed: 1990-07-27
Abstract: Cold water flows from a container into the heater (1) for heating by an electrical element (5) and to supply a brewing unit. The tea or coffee flows from the latter to a receiving container located on a heat retainer plate also heated by the throughflow heater. The drink is kept hot after the brewing process by temp. regulation of the heat retainer plate. The temp. regulation is selected by one of two siwtches (3, 4). Both these switches operate as open electrical switches above their differing openig temperature. Both switches are set such that they are closed during the brewing process. When the latter is completed the first switch (3) remains closed longer than the second (4). ADVANTAGE - Protects aroma even of small amounts.

Title: High pressure pump - has valves forming sub-assemblies to facilitate removal and replacement when worn
Inventor: EICKMANN KARL
IPC: F04B53/00
Filed: 1990-10-29
Abstract: A high pressure pump has a main assembly with inlets (6,7) and outlets (8,9) which are connected to valve asemblies (16) and (17), respectively. In the event of the valves becoming worn so that they no longer provide effective sealing, a complete valve asembly (16) or (17) can be removed and replaced. This feature obviates the need to dismantle the complete pump as is often the case with high pressure pumps of existing design. The time required for valve replacement is thus considerably reduced with a consequent reduction in cost. USE/ADVANTAGE - High pressure pumps with valves forming complete sub-assemblies which are easily removed and replaced.
