Title: Aircraft towed aerial gunnery target - has system of cords to front end of towing frame of random configuration at whose rear end they are secured
Inventor: YATES JOHN S
IPC: F41J9/10
Filed: 1980-06-25
Abstract: The assembly comprises strands or cords, each being secured at the forward end on a towing frame having various configurations. The towing frame is pulled by a conventional towing cable and may have arms that extend outwards upon deployment by aerodynamic forces, or may be rigidly constructed in the desired shape. The elongated cords extend backwards from the frame to a terminal point, such as an analogous frame or a confluence point, such as a ring, where they are attached in coupled relationship. The elongated cord elements avoid the coupling of vibratory motion from one cord element to another which results in the oscillatory flapping of targets constructed of conventional fabric. The cords are provided in an array such that they do not create aerodynamic lift and fluttering when being towed.

Title: Coffee-making machine with an outlet pipe for the rinsing water mixed with coffee grains
IPC: A47J31/60
Filed: 1981-05-02
Abstract: A device (14) for separating the coffee grains from the rinsing water is arranged below the outlet pipe (6) of the coffee-making machine. Said device comprises a tubular casing (15) on whose upper side there is an inlet aperture (16) for supplying the rinsing water mixed with coffee grains. A funnel-shaped, elastic closure member (29) with a small aperture (32) is fitted releasably onto one end of the casing. On the underside there is a slot-shaped cutout (26). Inserted in this cutout is a strainer (27) through which the rinsing water, but not the coffee grains, can emerge from the casing. A piston (19) is located inside the casing. During the displacement movement of the piston by means of a drive piston, the rinsing water is squeezed out of the coffee grains. For the coffee grains to emerge from the casing, a sufficient pressure must be exerted on the coffee grains in order to squeeze some of the coffee grains through the widening aperture (32) in the elastic closure member. Using the device described above, the coffee grains are separated from the rinsing water and kept out of the sewerage system. <IMAGE>
