Inventor: SCHRODER PETER
IPC: F23J13/02
Filed: 1988-08-26
Abstract: Element, which can be inserted with clearance into a prefabricated chimney shell, consists of an internal tube (1), a heat insulating layer (2) applied to the external surface of the internal tube (1), and a material web (3) which surrounds the heat insulating layer (2) and holds the heat insulating layer (2) pressed together. After insertion into the chimney shell (12), the material web (3) is pulled off so that the heat insulating layer (2) expands. In rear-ventilated chimney shells, the heat insulating layer (2) also penetrates the ventilation ducts (13) of the chimney shell (12) and blocks these ducts (13). The material web (3), which consists of a non-flammable or hardly flammable material, has at least one region (4) extending in the longitudinal direction of the tube with overlapping sections which are held together by a releasable connection (7) so that, by releasing the connection (7), a given predetermined expansion of the heat insulating layer (2) is achieved. <IMAGE>

Abstract: The high power radiation source for visible light consists of a discharge cavity (4), bounded by dielectrics (1, 10) and filled with a noble gas or gas mixture. Luminescent layers (5, 11) are connected to the dielectrics (1, 10). Both the dielectric (1, 10) and the electrode (6, 12) located on the surfaces of the dielectrics facing away from the discharge cavity (4) are transparent for the radiation which is generated by silent electrical discharges. In this way, a large-area radiation source with a high efficiency is produced, which can be operated with high electrical power densities up to 50 kW/m<2> of active electrode surface.

Abstract: The series resonant circuit filter consists of a basic filter circuit (L1, T, C1) and a damping circuit (R, C2) which is connected to the secondary of the magnetic coupler (T) via a switch circuit (Sc). The coupler (T) is part of the total inductance (L1, T) of the basic filter circuit (L1, T, C1). The transformation ratio of the magnetic coupler (T) is selected to be greater than unity so that the sizes of the damping elements (R, C2) are transformed up accordingly. As a consequence, more compact, more cost-effective and more reliable damping elements can be used. The damping elements (R, C2) are then  deliberately connected to the basic filter circuit (L1, T, C1) with the aid of the switch circuit (SC), when the stability of the supply network makes this necessary. The damping elements (R, C2) thus do not load the supply network in an uninterrupted manner. <IMAGE>

Abstract: Dispositif à clapet destiné à communiquer avec un espace (8) contenant un fluide sous pression, par l'intermédiaire d'un premier tube de connexion (6) et à permettre la sortie de ce fluide sous pression et la communication avec une source de fluide sous pression par l'intermédiaire d'un second tube de connexion (5). Le dispositif à clapet est disposé de manière qu'une pression résiduelle soit maintenue dans l'espace renfermant le fluide sous pression mais aussi de manière à permettre d'alimenter l'espace en fluide sous pression, lorsqu'on exerce une pression sur le second tube de connexion. Ce dispositif à clapet comprend deux clapets anti-retour (9, 10) dont l'un se ferme pour empêcher le fluide sous pression de s'écouler hors de l'espace quand la pression dans celui-ci tombe au-dessous d'un certain niveau tandis que l'autre clapet s'ouvre lorsqu'une pression s'exerce sur le second tube de connexion. Les clapets anti-retour sont placés dans deux chambres différentes (11, 12) du corps (3) du dispositif à clapet. Chacune de ces chambres est accessible de l'extérieur du corps par une ouverture (13, 14 respectivement séparée des orifices extérieurs de chacun des tubes de connexion afin de permettre respectivement la pose et la dépose, voire le réglage des clapets ou de leurs pièces par ces ouvertures.

Abstract: The peristaltic pump according to the present invention is of the type in which a looped tube is squeezed by the rotating rollers in a housing. The improvements according to the present invention in a pump of this type reside in that a flexible tube having a large wall thickness for its inner diameter is stretched to a suitable length and passed around rollers so as to apply a suitable tensile force to the tube, whereby a fluid delivery speed and pressure far higher than those with a conventional pump of the same type can be attained. This enables the tube to be replaced very easily, and the range of application of the tube pump to be greatly increased.

Abstract: The invention provides apparatus for use in dipping animals, especially sheep, in a liquid solution of insecticide. The animals enter a dry bath (4) through entrance (5) which is then closed. Liquid solution is then pumped into the bath (4) to immerse the animals and pumped out again. Exit (6) is then opened to allow the animals to leave. In this way there is avoided the injury or loss usually associated with putting unwilling animals into a bath already full of liquid solution. A high throughput can be achieved by operating two or more baths in parallel, pumping the liquid solution alternately from one to the other, so that animals are dipped in one while entering or leaving the other.
