Abstract: A golf bag includes a bag body, a head frame, a chassis and a supporting mechanism. The supporting mechanism is configured on one side of the bag body, comprising two support bars and two elastic bars. One end of the two support bars is pivoted on the head frame. The two elastic bars are relatively pivoted between the chassis and the two connecting blocks configured on the two support bars. It is characterized in that: the supporting mechanism further comprises two limiting members, respectively configured at the pivoting position of the two support bars and the two elastic bars, to limit the pivoting position of the two support bars and the two elastic bars.

Abstract: A method for compressing a data stream based on a combination of two digests is used. Each combination of digests that occurs multiple times is assigned a codeword. When the first digest matches, a data structure of second digests occurring with the same first digest is built, associating each combination of digests with a position in the stream where the combination of digests is found. When a new match is found a new codeword is defined. When a match with an existing codeword is found, a byte sequence is emitted that identifies the codeword associated with the matched data. When a partial match is found, the length of a codeword is changed and a corresponding byte sequence is emitted. The method finds particular application in data streams that are sent to printers, and which contain large blocks of identical data such as images or repetitive text.

Abstract: A method for compressing a data stream based on a 3 byte sequence is used. Each three byte sequence is assigned a code word including a location and a length of the data associated with the code word. When a 6 byte sequence is located, a binary tree of 6 byte sequences sharing the same first three bytes is built, associating each 6 byte sequence with a position in the stream where the 6 byte sequence is found. When the length of a code word is changed, a byte sequence is emitted that identifies the code word to be changed and updating the length of the code word, so that when a match is found, a byte sequence is emitted that identifies the code word associated with the matched data. The method finds particular application in data streams that are sent to printers, and which contain large blocks of identical data.

Abstract: A unit for separating waste and valuable materials with several mutually connected waste containers, which are equipped with identifying features labeling these waste containers for the purpose of assigning a particular waste or recyclable fraction to them. The unit for separating waste and valuable materials is constructed so as to be adaptable in modular fashion.

Abstract: An electrostatic powder coating booth has double walls which can be evacuated to hold replaceable cover foils thereagainst so that, for a color change, a contaminated stretch of foil can be replaced by a fresh stretch of foil.

Abstract: A wine cooling apparatus comprises a bottle holder which holds a bottle within an ice and water mixture in a container which is rotatably mounted on a turntable. When the turntable is rotated, the container rotates and fins on the inside of the container stir the mixture and cause it to swirl around the surface of the bottle thereby cooling the wine.
