Title: Liquid dispenser for adjustable small volumes+ -  using screw fitting cap with measurement chamber emptied by pressed membrane on cap
Inventor: KEIL GEORG
IPC: G01F11/26
Filed: 1992-11-12
Granted: 1994-04-07
Abstract: The dispenser (4) is screwed onto a glass container (1) by a threaded section (5) and sealed by a lip (6) to the container neck surface (3). The outer section (15) is fixed by a screw thread (17) to the inner section (10) so as to be adjustable. The separation between two sections (10 and 15) forms a measurement chamber (19) whose volume is adjusted by turning one section (15) on a screw (17). The cap section (28) is a deformable membrane. By inverting the container, liquid fills the cavity (30) and drain at an overflow tip (8). Measured volume is then dispensed by moving a cylindrical valve (23) to allow outflow via an opening (19a) from measurement cavity and a spigot (25) under pressure from membrane deformation (29). USE/ADVANTAGE - Repeatable dispensing of small volumes of liquid in adjustable quantity.

Inventor: WAZEL WILHELM DIPL ING
IPC: B65D51/16
Filed: 1992-12-08
Granted: 1993-12-23
Abstract: Described is a closure, in particular for bottles, with a cap (11), in particular a screw-on cap, made of plastic or a similar material, which is designed to be placed over the neck (10) of the bottle, and with a closure membrane (16) which rests against the top (15) of the cap. The closure membrane (16) rests against an annular rib (19) extending round the inside of the cap above the rim (17) of the bottle mouth (18). This support rib (19) is joined to the cap top (15) or the closure membrane (16) in such a way that, when an overpressure inside the closed bottle causes the closure membrane (16) and cap top (15) to bulge outwards, the closure membrane is lifted by the pressure away from the rim (17) of the bottle mouth (18), thus allowing the interior of the bottle to be automatically vented (arrow 20).

Patent DE-4400234-C1 (DE)
Inventor: LOESEL THOMAS DIPL ING
IPC: G01R31/02
Filed: 1994-01-05
Granted: 1995-08-03
Abstract: The method involves using voltage (12) and current potential (14) transducers with respective analog to digital converters (2,1) and a microprocessor controller (9). The variation with time of the energy consumption from a rail network at, or in, a motor is evaluated and measured. If the consumption exceeds a certain threshold, the network brakes are disconnected (3), e.g. those which convert and feed vehicle kinetic energy back into network electrical energy. The energy consumption variation with time is found from the first derivative of the current fed back into the network w.r.t. time. The variation can also be found from the incremental change of current over a certain time interval.
