Abstract: The present invention is related to a dispenser, which is filled with a gel comprising a C1 to C10 carboxylic acid and a thickener, comprising a polyester membrane. The invention further relates to said gel. It also relates to s method for preparing said dispenser, comprising a) mixing C1 to C10 carboxylic acid and the thickener, and b) filling the mixture of step a) into the dispenser. The invention further relates to a method for the control of mites in bee hives comprising putting said dispenser inside or near a bee hive. It also relates to a use of the dispenser or the gel for the control of mites or of nosema in agricultural, industrial or domestic environment.

Abstract: Bonding (1) of a plastic fixture (2) to a glass container (3), comprising a glass container (3) with an opening area (8) bearing an opening (6) and a plastic fixture (2) with two walls (11, 12) enclosing both sides of the wall (20) of the glass container (3) in the opening area in circumferential direction, a first inner wall (11) and a second outer wall (12). The opening area (8) has an area of lesser external dimensions on the outer circumference than on the opening (6). A wraparound element (19) interrupted in circumferential direction which encloses the opening area (8) in the vicinity of lesser cross-section and supports itself on the wall (20) of the glass container (3). The plastic fixture (2) is positively connected with the wraparound element (19).

Abstract: Closure members are provided at the opposite ends of a hollow casing. Shock absorbers are confined within the casing by the closure members. A weight is disposed within the casing between the shock absorbers. The weight may be defined by a plurality of granules confined within an enclosure in the casing between the shock absorbers. Alternatively, the weight may be defined by a solid member. The casing may be in the shape of a baseball bat. Alternatively, a tube may be disposed within the casing and may be closed by the end caps. The shock absorbers and the weight may be confined within the tube by the end caps. The arrangement described above may also be provided in different types of balls. For example, end caps may be provided at the opposite ends of a hollow main body shaped to define the central portion of a football. Shock absorbers may be disposed with the hollow main body at positions interior to the end caps. A weight may be disposed within the hollow main body between the shock absorbers.

Abstract: A long-wall mining machine has an operating chain entraining conveyor flights or mining tools and displaceable in a trough which can be provided with rows of sensors of an inductive proximity type responding to the chain and the tools and generating measurement pulse trains which are compared with setpoint pulse trains to signal functional parameters of chain operation. The sag of the chain is determined by a row of sensors and in response to the sag a chain-tension unit can be controlled.

Abstract: A sports implement, such as a tennis racket, baseball bat or golf club, includes an audio feedback device to provide an audible indication of the speed of movement of the sports implement. The audio feedback device includes ridges and grooves formed along the length of one of the structural members of the sports implement, such as along the shaft of the golf club, along the length of the baseball bat, along the handle of the tennis racket, or along the lateral sections of the head of the tennis racket. The ridges and grooves are configured to provide an audible indication when the sports implement is being swung at a proper speed. The audio feedback device can be a separate tubular member which is mounted to a generally conventional sports implement or it can be created by appropriately configuring the surface of the sports implement.

Abstract: A ball support device is used for supporting a ball at an elevated position so that the ball can be struck while so supported with a bat, club or like sports implement. The ball support device includes a base, a post and a ball holder fitted to the upper end of the post. The post is formed from two telescopically interconnected members, and a friction grip means is provided for fixing the two members relative to each other at a selected height. The holder may itself be flexible and the connection between the base and the post is preferably resiliently flexible so that an articulated connection between post and base is achieved, and the post is biased to its operatively vertical orientation. The components are preferably all easily disengagable from each other so that the device can be erected and disassembled without difficulty.

Abstract: This invention provides a rebound net, for use in practising tennis, cricket, baseball and/or other games, having a surrounding frame and a net capable of being mounted in the frame, the net being made of a tough, low-extensible material such as nylon with the threads of the net fastened together at their intersections, and a number of attachment clips for fastening said net to the frame, when the attachment clips are arranged around the frame, in such manner as to hold the net under tension sufficient to provide at least 80% rebound in a tennis ball when dropped upon a mid-portion of the net in horizontal position. The net is arranged so that the threads thereof, when the net is held in the frame under tension, extend from the bottom of the frame upwardly on opposite sides of a vertical center line at equal angularity to that center line. That is to say, for a net with a square mesh the diagonals of the mesh extend horizontally and vertically when the frame is in an upright operative position.
