Title: Cableway system for transporting persons or goods
Inventor: DIETMAR FESSLER
IPC: B61B7/00
Filed: 2014-06-03
Abstract: Disclosed is a cableway system where the position of the carrying rollers can be adjusted relative to the traction cable to improve wear of the rollers, particularly when the cable path is transversely or horizontally curved. The cableway system for the transport of persons or goods has two pairs of track cables, which extend between two terminal stations, such as a valley station and a mountain station. Transport vehicles, such as gondolas carriages, are moved along the track cables by at least one traction cable. The track cables run in a curved path in the region of at least one tower and the traction cable is guided in the region of the at least one tower via carrying rollers. At least some of the carrying rollers for the traction cable, which are located in the region of the at least one tower, are adjustable in terms of their position in relation to the two track cables where the traction cable is mounted on a pivot arm that is pivotable in height about a substantially horizontal axis under the action of an adjustment mechanism, which in turn is operated by a resilient spring. The track cables rest, in the region of the at least one tower, on two supporting plates, and the pivot arm, on which a carrying roller for the at least one traction cable is mounted, is supported pivotally in height.

Title: Vacuum laundry chute system
Inventor: HENRY DREW P
IPC: D06F95/00
Filed: 2016-11-18
Abstract: A laundry system (100) is disclosed. The system includes a receptacle (110), at least one chute (120), and at least one closure (130). The receptacle (110) includes a vacuum device (202), a cavity (204) for receiving an article of clothing, a container (206) to surround the vacuum device (202) and the cavity (204), and a door (208) coupled to a side of the container (206). Activating the vacuum device (202) seals the door (208). A first end of the chute (120) is coupled to the receptacle (110) and protrudes away from the receptacle (110). The at least one closure (130) is detachably couplable to a second end of each chute (120). The closure (130) includes a sealing component (504) detachably couplable to the second end of the chute (120), and an activator (508) mounted to the sealing component (504) to activate the vacuum device (202) in response to a pre-defined condition. Many factors can make doing laundry difficult. Laundry may be scattered about a house while the laundry facilities are located in one part of the house. In some cases, the laundry facilities of a house may be in an upper floor of the house and the laundry must be carried up to the facilities. The laundry system provides a chute that can create either a positive or negative pressure when the activator (304) sends a signal to the internal circuitry. This laundry system that either generates positive or negative pressure allows laundry from around the house to be brought to laundry facility thus saving time and reducing labour.

Title: Vehicle identification means
Inventor: BEENKEN BJÖRN
IPC: G06K19/07
Filed: 2019-03-26
Abstract: Vehicle identification means are used to identify vehicles by means of a unique identifer. The protection of said means from forgery and tampering is a particularly problematic issue. Known vehicle identification means have readable data carrier on which data for the clear identification of the items is stored and which can be read without contact. Identification means of this type are however very complex and susceptible to malfunctioning. The invention provides an improved vehicle identification means (10) which has as simple a design as possible and which is less susceptible to malfunctioning. For this purpose, an identifying element (11) is associated with at least one NFC transponder (19), readable without contact, for near-field communication with a data carrier (21) and an antenna (20), at least part of said antenna (20) being arranged in a through-opening (16). The inventive concept is that the NFC transponder together with the antenna structure is arranged over an aperture of the license plate body. Thereby, two opposite sections of the antenna are arranged over the aperture/breakthrough. This breakthrough/aperture improves the range of the signal.

Title: Ascendable path for fishes faced with technical obstructions
IPC: E02B8/08
Filed: 1995-03-02
Abstract: The invention is characterized by a succession of tanks, in concrete structures, attached to one or both margins, arranged longitudinally to follow a line with a gentle downward slope, resulting between the upper level of the waters of any lagoon and the lower level, at a downstream point. It makes it possible, in the set of n tanks with level difference between collateral tanks of < 0.50 m and length of 2 m to 3 m, to establish a series of cascades with a gentle and controlled flow rate via a (descending) lock gate and to supply the first three upper tanks. In this manner, per se, fish species are able to execute the saltigrade ascent and are enabled to spawn (lay their eggs) naturally, upstream of the obstruction on the bed. This path for fishes needs to be protected over its entire route or only at sensitive points (accessibility) by a lattice structure against predation, especially in the area of the seasonal supply of rushing water into the system. <IMAGE>
