Title: An apparatus for preparing filter coffee
Inventor: SCHMED ARTHUR
IPC: A47J31/46
Filed: 1997-03-21
Abstract: In order to generate steam in an apparatus for preparing filter coffee, a design is proposed which comprises a water storage container and a device for separating water and steam. A heating element is provided for heating water and for generating steam.          The separating device comprises an inlet connected to the outlet of the heating element and an outlet connected to a steam nozzle.          The water storage container comprises an inlet connected to a fresh water tank and an outlet connected to the inlet of the heating element. Moreover, a throttle member is provided close to the outlet of the water storage container; the throttle member restricts, during the generation of steam, the amount of water fed to the heating element per unit of time. By means of such a design, dry steam, particularly suitable to prepare a cappuccino beverage, can be generated in a simple manner.

Title: Self-locking sealing device
Inventor: MARC JEAN-PIERRE
IPC: F16B39/282
Filed: 1995-11-07
Abstract: A seal including a body (11) with a recess (8) at one end engageable by a spanner, and a screw thread (2) at the other end for engaging a complementary screw thread (7) in an opening (6) of a housing (3). A locking ring (31) biased by a spring in the seal (1) and a complementary locking ring (47) in said opening have asymmetrical teeth which interlock when screwing-in is complete and snap together to prevent loosening of the rings. The tooth flanks that engage one another on loosening are nevertheless sufficiently angled to enable forced unscrewing using a spanner. A skirt (14) protects the mechanism and acts as an abutment in the fully screwed-in position. Said seal enables locking and unlocking, requires no direct manual operation and is particularly suitable for endoscope insertion openings in aircraft engines.

Patent CA-2220295-A1 (CA)
Inventor: HEADLEY THOMAS D
IPC: B04B5/04
Filed: 1996-03-05
Abstract: The system includes a needle (72) (or other cannula-like device) for insertion into a vein of the donor and drawing whole blood therethrough, a variable-volume rotor (2a) for holding the blood after it is drawn, and a motor (50) for spinning the rotor so as to cause the blood to seperate into components, for example, plasma and red blood cells. The system also provides for a container for collecting a separated component. In a preferred embodiment two containers are used: the first container (92) for containing an anticoagulant, which is preferably added to the whole blood as it is drawn from the donor, and then for storing the plasma after it has been separated from the red blood cells, and the second container (91) for storing the separated red blood cells. The system further includes tubing (73), which may have valving (81) built into it and which may be acted on externally, so as to direct the blood components in the desired manner. The tubing connects the needle (72), the rotor (2a), and the first and second containers (92, 91). With the valving, the tubing is able to permit (i) the flow of whole blood from the needle (72) to the rotor (2a), (ii) the flow of anticoagulant from the first container (92) to the whole blood flowing from the needle to the rotor, (iii) the flow of plasma from the rotor to the first container, and (iv) the flow of red blood cells from the rotor to the second container (91).  The motor (50) and the valving are preferably controlled by an electronic controller. Preferably, the system also includes a pump (61), which is also controlled by the controller, and which forces the blood components out of the rotor (2a) to the tubing. The pump is preferably able to draw the whole blood into the rotor.
