Abstract: Apparatus for the practicing of golf swings has a club member (10) to be swung by a user in simulation of the swinging of a golf club, the club member (10) having a simulated golf club handgrip and a source of radiation for providing a beam (14) extending from one end of the club member (10) in the longitudinal direction of the club member, the beam having a flat leading side. Sensors responsive to the radiation for sensing the swinging of the club member (10) are disposed in a predetermined array in the vicinity of a simulated golf ball impact location for providing sensor signals in response to the passage of the beam over the array. The sensor signals are processed for providing first signals corresponding to the direction of travel of the beam, second signals corresponding to the speed of travel of the beam and third signals corresponding to the orientation of the beam. The first, second and third signals are employed for computing a golf ball flight and providing corresponding output signals to a monitor (24) for providing a visual representation of the flight of the golf ball.

Abstract: The golf course simulator comprises a track (5) between a driving point (3) and a fronton (8). The track (5) comprises a multiplicity of holes (6) which can be covered. The fronton (8) marks the boundary of a virtual space where a target hole is located in the first phase of the game, where the shots are long range shots, and a real space, where the target hole is represented by the opening of a hole (7), when the player is sufficiently close to the target hole. A suitably programmed computer (11) controls the simulator. For long range shots, the driving point (3) comprises a ball detector, and the fronton (8) comprises an impact-detecting matrix. The measurement of the duration between the departure of the ball and the impact on the fronton (8) at a known distance and the location of the impact on the fronton provides information on the initial velocity, lift and deviation which allows the arrival of the ball in the virtual space to be determined, and target parameters to be deduced from these. When the target hole is in the real space, a hole (7) is open, and the driving length, detected by detectors (10) distributed along the track, results in the opening of another hole, corresponding to the remaining distance to be travelled.

Abstract: The cable terminal (2) is intended to connect to a current-supply cable a foil strip electrode of a flexible heating panel which presents insulating covering sheets on its two main faces. The cable terminal (2) comprises, in one piece a socket (20) for setting the cable, and a slab (21) provided with six claws (22) obtained by puncturing, along two equal sides (23,24) of an isosceles triangle with a vertex angle close to 30 DEG  and bending at right angles along the third side (25) of the triangle. For contact with the electrode, the slab (21) is pressed, claws (22) first, on to the covering sheet of the upper face of the panel opposite the electrode, in such a way that the claws perforate the superimposed layers of the panel, and traverse the electrode until the slab (21) rests on the panel. The claws (22) are folded back by bending parallel to the bend (25) under the panel, in a direction opposite to the punctured aperture (26), in such a way that their points are pressed against the panel over a substantial portion of their length. <IMAGE>

Abstract: Selon un procédé efficace de récupération à long terme de cristaux contenus dans des boues, les boues sont introduites dans un filtre rotatif à vide et filtrées à vide pendant la mise en rotation d'un organe cylindrique de filtrage. Une pression est appliquée sur le côté des boues afin de maintenir la température et la pression à des niveaux qui empêchent la supersaturation du filtrat du filtre rotatif à vide. Ce procédé permet d'éviter l'obstruction de l'organe de filtrage due à la précipitation des cristaux contenus du côté de l'eau-mère ou à une augmentation de la viscosité, et permet de récupérer pendant longtemps les cristaux contenus dans les boues. Ce procédé convient pour récupérer des cristaux d'acide téréphtalique brut ou purifié et il peut également être utile pour récupérer des cristaux en général, tels que l'hydroquinone ou le résorcinol, contenus dans des boues.

Abstract: La présente invention concerne un système de purification d'eau qui crée un écosystème intégré à petite échelle d'eau de mer ou d'eau douce, cet écosystème étant particulièrement utile en tant qu'aquarium de laboratoire, de bureau, d'école ou domestique. En fonctionnement, l'eau provenant du réservoir (56) de l'aquarium est acheminée vers un écran épurateur d'algues (10) ou une surface équivalente de croissance d'algues placées dans un réceptacle mobile, sensiblement plat, placé horizontalement et en forme de plateau (21). Une tourbe d'algues (14) comprenant de préférence une colonie dense de microalgues se trouve sur l'écran (10). Au fur et à mesure que le réceptacle (21) se remplit d'eau, le centre de gravité du réceptacle (21) se déplace sur l'axe (25) des pivots (24) sur lesquels est monté le réceptacle (21). A ce moment, le réceptacle (21) rempli d'eau tourne sur ses pivots (24) et on obtient un effet de contre-foulement désiré au travers de l'épurateur (10) par l'eau qui sort. Le reflux ou contre-foulement, l'énergie lumineuse fournie par des lampes (18, 32) placées au-dessus du réceptacle (21) et la photosynthèse des algues favorisent l'échange métabolique entre les cellules et l'eau ambiante pour éliminer le dioxyde de carbone et d'autres substances polluantes.

Abstract: The method of making polystyrene foam for foam products which comprises utilizing atmospheric gases as the blowing agents or preferably mixing one or more of these gases and a blending agent which is non-volatile at the extrusion temperatures, introducing the mixture to a molten thermoplastic polystyrene resin containing nucleating agents such as sodium bicarbonate and citric acid and extruding the thermoplastic in the form of a foam. The resultant foam has substantially no residual blowing agent, is dimensionally stable at ambient temperatures and when used with a non-volatile blending agent can be made with small amounts of blowing agent permitting cooling of the melt without high loading on the extruder. The foam may be coextruded with one or more layers of thermoplastic film so that the resultant product is adapted for use for plates, cups, food containers or packaging and for labels for containers such as glass and plastic containers and for labels that are shrunk in place on a container.
