Title: Sports racket.
Inventor: SVOMA RODNEY
IPC: A63B49/02
Filed: 1989-08-17
Abstract: A sports racket which is made by joining longitudinal sections of a racket, particularly half sections of a racket, along a plane parallel to the center plane through the playing surface of the racket. The longitudinal sections of the racket define recesses to form hollow spaces within the interior of the racket upon joining of the racket half sections to thereby reduce the weight of the racket while maintaining its strength. This racket construction is also combined with a string suspension system which includes strings which are splayed to alternately contact the racket frame in front of and behind the plane of the playing surface, contributing to the strength and integrity of the frame.

Abstract: A wear-resistant coating on, in particular, the running surfaces of piston rings for combustion engines is produced by applying metals or alloys containing in particular the nitride-forming or carbonitride-forming metals chromium, molybdenum, tungsten, vanadium and/or titanium and optionally added amounts of metal compounds by remelting with alloying in the melt with the base material and subsequent nitriding or nitrocarburisation in the salt melt or from the gas phase, and it has been found that these layers also have improved fire safety under extreme conditions in addition to improved adhesion, wear-resistance and break-out resistance. The coated piston rings can be used in particular in medium-fast to slow diesel engines with a high thermal and combustion pressure load.

Abstract: 1. Housing box for a thermal protection switch. 2.1 It is known for thermal protection switches to be fitted in the encapsulated state in a thermally connected manner to the active part of electrical machines. This necessitates a corresponding assembly cost and, in addition, particularly thermal protection switches which operate as a function of current require a corresponding installation volume. The new housing box is intended to permit thermal protection switches to be fixed on the wound stator such that they can be removed and without being incorporated into the field winding. 2.2 The housing box (10) is dimensioned and shaped such that it can be accommodated in the intermediate space (25) between the winding head (26') of the field winding (26) of a salient pole stator and the stator laminate stack (28'), and can be fixed in its in-use position (Fig. 6). <IMAGE>

Abstract: L'oscillateur commandé par tension décrit comprend un calculateur de valeur de signal de compensation, qui calcule la valeur d'une fonction représentant la partie de la courbe de transfert température-fréquence de l'oscillateur qui correspond à la température ambiante. Un signal correspondant à la valeur calculée est ensuite appliqué à l'oscillateur commandé par tension comme tension de commande. Fondamentalement, une courbe de transfert température-fréquence d'oscillateur est divisée en n segments. Pour chaque segment, une valeur de déplacement xn, égale à la différence entre la fréquence au début du segment et la fréquence désirée, est stockée dans une table de consultation. Lorsqu'une valeur de signal de compensation est requise, le calculateur de valeur de signal de compensation extrait de la table de consultation les valeurs xn qui correspondent au segment contenant la température ambiante, qui est le segment ''k'', et aux segments placés immédiatement avant et immédiatement après le segment k, qui sont les segments ''k-1'' et ''k+1''. Les valeurs extraites sont marquées xk, xk-1 et xk+1, respectivement. Le calculateur calcule ensuite une fonction représentant la partie de la courbe de transfert passant par trois points correspondants aux valeurs (2). La valeur du signal de compensation est ensuite calculée par remplacement de la valeur delta T effective dans l'équation. Si la fréquence de sortie de l'oscillateur a subi un déplacement dû à un vieillissement du cristal, une valeur de déplacement de vieillissement, xA est ajoutée à l'équation, et le signal de compensation compense les variations de fréquences relatives à la fois à la température et au vieillissement.
