Granted: 1999-02-01
Abstract: Devices for preparing a variety of hot drinks, such as, in particular, espresso machines, usually have a multi-path valve (2) which is used for conveying hot water or superheated steam generated in a water heater to different appliances, such as coffee filter, foaming nozzle and/or container. Due to the high temperatures and pressures, the multi-path valve is subject to considerable loads, which known valves cannot withstand or can withstand only if they are of complex construction. In the new device the multi-path valve is provided with a punched plate (8) and a rotatable plate cam (9). Rams (14) for closing distributor channels (5) are passed through the holes of the punched plate. The distributor channels are provided in a distributor block (1) on which the multi-path valve is flange-mounted. The position of the rams is determined by the rotational position of the plate cam provided with a guide crank for the rams.

Title: Universal electric levelling indicator
Inventor: IFTIME ADRIAN
IPC: G01C9/34
Filed: 2000-09-11
Abstract: The invention relates to an electric levelling indicator with illuminated signs, meant for verifying the horizontality, the verticality, the inclination of some surfaces, especially in industrial and civil buildings, land surveying, laboratories, etc. The universal electric levelling indicator comprises a body (1) wherein a glass tube (4) bent downwards there is mounted, having a mercury bubble displaceable therein, said bubble closing the supplying circuits of some indicating lamps (26 ... 30) by means of a pair of electric contacts (6-7, 8-9, 10-11, 12-13 and 14-15) mounted inside the glass tube (4). The indicating lamps (26 ...30) are visible from the outside and correspond to some variations of +/- 1 in relation to the horizontal of verified surface. In order to verify the verticality and to measure bigger inclinations, the body (1) of the levelling indicator may be swingable with respect to a base (2) which makes one piece with a protractor (3), the reading of the inclination being made on the scale (j) with instrumental dial of the protractor (3) through a window (h) in front of an index (i), printed on the body (1).
