Title: Ostomy coupling
Inventor: WILTSHIRE NEIL P
IPC: A61F5/448
Filed: 1989-11-09
Abstract: A three part ostomy coupling has a first part 20 having a flange, a central chute 22 and an array of spaced arcuate walls; a second part 10 having a peripheral seal for engaging and surrounding the outer wall of the chute and an outwardly projecting rim capable of a snap fit with the spaced arcuate walls; and a third part 30 which is rotatable about the arcuate walls in order to effect a positive lock between the rim and the arcuate walls. The third part or locking ring 30 has on its upper surface ridge-like projections 34 which engage the arcuate walls on rotation of the ring. These effect a secure locking of the coupling elements 10 and 20.

Abstract: Présentation d'une méthode de formation d'une extrusion composite dans laquelle une partie du corps principal (1) de l'extrusion est d'abord extrudée à partir d'un matériau thermodurcissable, cette partie du corps est ensuite chauffée de manière à la cuire au moins partiellement. La partie du corps principal est alors passée à température élevée par une autre extrudeuse où un matériau thermoplastique (8) est extrudé sur une surface ou plus de la partie du corps principal (1). L'extrusion composite subséquente est alors refroidie et elle reçoit sa forme finale. Il est important que l'étape de combinaison soit entreprise à une température suffisamment élevée pour provoquer la liaison du matériau thermoplastique au matériau thermodurcissable et bien qu'il soit plus simple que le matériau thermoplastique se trouve sur une surface extérieure de l'extrusion composite, il est possible de le placer à l'intérieur du matériau thermoplastique en extrudant le matériau thermoplastique dans un mode « ouvert vers l'extérieur » et, après l'extrusion du matériau thermoplastique et pendant que l'extrusion est encore chaude, plier dans les zones de bordure de la partie principale du corps pour recouvrir le matériau thermoplastique  et le coller à cet endroit. Le matériau thermoplastique peut avoir une couleur spéciale; il peut être gaufré, et s'il est placé à l'intérieur du matériau thermodurcissable du produit fini, il peut être plus rigide que ce dernier. L'invention porte également sur les extrusions elles-mêmes.

Title: Communication line filter
Inventor: FREY WILFRED
IPC: H04B3/28
Filed: 1990-11-05
Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a communication line filter for use in series with communication lines.  The communication line filter provides for surge protection from voltage spikes and provides frequency filtering to remove selected interference signals from other radiating sources.   The communication line filter comprises: two signal conductors linked together by a fuse;  a common signal ground; and two shunts for shunting a surge current between  the  signal  conductors  and  the  common  signal ground.  The shunts provide protection from short duration voltage spikes while the fuse provides protection from longer duration overvoltages.   The communication line filter functions effectively, independent of the direction of current flow along the communication line with respect the line filter.  The two shunts and the fuse are selected to  provide  the  required  capacitance  and  impedance respectively, to form a suitable frequency notch filter.
