Abstract: A propulsion device for use in propelling a curling rock comprises a head which engages a rock so as to apply a pushing action from an elongate handle so that the player can stand while pushing the handle and applying the propelling force. On the rock is mounted a tubular member carried on the handle of the rock which has a surface for engaging a pair of arms on the propulsion head so that the tubular member is aligned at right angles to the line of propulsion. A loose cable extends from the head to a fastener on the tubular member at one end of the tubular member with the amount of force applied by the fastener before release being variable. Thus, as the rock leaves the head after the propulsion stroke, the loose cable tightens and applies a rotation force on the tubular member and therefore the handle up to a predetermined rotation torque depending upon the selection of the fastener element. Thus the rock is propelled with a variable propulsion force and a variable rotation rate both of which are selectable by the player.

Abstract: Système utilisant une structure de disque optique permettant de représenter plusieurs signaux synchronisés tels que, par exemple, plusieurs versions d'images cinématographiques et plusieurs pistes sonores, et constitué d'un disque optique (23), de processeurs de signaux (67, 71), de circuits tampon (53, 55, 57, 59) et de dispositifs de sortie audio (91) et vidéo (94). Tous les signaux sont représentés de manière numérique, et les bits sont groupés dans des blocs de données. Chaque bloc de données peut contenir un nombre variable de bits associés à chaque signal, ce nombre variant entre zéro et un chiffre élevé (par rapport aux autres signaux). Ainsi, chaque signal est représenté par un train binaire à vitesse variable sans qu'un signal n'en limite nécessairement un autre, pour ce qui concerne la représentation binaire. Plusieurs tampons permettent d'assurer que le nombre de bits disponibles pour chaque signal est suffisant pour satisfaire des besoins immédiats. Lorsqu'un tampon est plein, la lecture des blocs de données s'arrête momentanément de sorte qu'aucun bit ne soit perdu.
