Title: Thermally powered engine.
Inventor: CLARK ROBERT W JR
IPC: F01K7/12
Filed: 1986-10-16
Abstract: A thermally powered engine which obtains energy from a closed heat transfer loop. The engine has two power cylinders. A piston is reciprocally mounted within each cylinder and divides the interior space of each cylinder into two portions. A piston rod is affixed to each piston and extends through the upper closed end of each cylinder. A flexible diaphragm is mounted in the lower portion of each cylinder and with the lower closed end of the cylinder forms a power chamber. A fluid fills the upper portion of both cylinders. A passageway between the cylinders permits the fluid to act as a free piston causing the piston of the cylinder in its exhaust stroke to force refrigerant from its power chamber to the condenser of the heat transfer loop. Refrigerant from the evaporator of the transfer loop flowing into a power chamber forces the piston upward during the pistons power stroke. Valves regulate the flow of refrigerant into and out of the power chambers of each of the power cylinders. Flow of refrigerant is controlled so that motion of the pistons of the two power cylinders is 180 DEG  out of phase. Several pairs of power cylinders can be connected in series with the refrigerant flowing through the pairs serially prior to reaching the condenser. Isothermal sequential displacement of the refrigerant through the power chambers of a series of pairs of power cylinders increases the thermal efficiency of the engine.

Abstract: This device for actuating a tip-up or sectional door comprises an elongated frame structure supporting a linearly movable member driven through a worm screw or a chain connected to the door to be driven, and secured at two upper points of which one is located at one end of the frame structure. This one end is secured to a fixed support formed with a vertical notch of which the bottom edge has a groove formed therein, the upper edge of this notch being limited by a surface located at a predetermined distance from the groove bottom. The frame structure comprises a support surface, for example in the form of a pin, and a locking surface, for example in the form of another pin, located at a distance from the first pin which corresponds to the predetermined distance. This frame structure can be fitted by a single person by anchoring the lower pin of the support and then raising the frame structure to a substantially horizontal position, so as to lock automatically the device in its operative position.

Abstract: The apparatus includes a smoothing and flattening device revolving above the filter medium. The distance between the filter medium and the smoothing and flattening device can be varied by lifting and lowering an intermediate plate which carries the filter medium, the lowered position corresponding to a filtration position, and the lifted position corresponding to a clearing position in which the filter cake is cleared from the filter medium by means of the smoothing and flattening device. By means of an outlet orifice formed at a suitable point, the filter cake can be mechanically cleared out of the filter apparatus without it being necessary to tilt the latter. Due to the mobility of the intermediate plate, it is not necessary for the drive shaft of the smoothing and flattening device to be axially displaceable. The shaft seal on the drive axle can therefore be provided as a simple mechanical seal. <IMAGE>

Abstract: An optical analyzer for determining changes of the polarization plane in a light beam (4) comprises a substrate (20) supporting a photo-detector array (21) and a system of imaging mirrors (22 - 24) underneath a parallel plate (25) of high quality optical glass. The lower surface of the glass plate is covered by a system (26) of dielectric multilayers which acts as a polarizing beam splitter over a large range of angles of incidence. The optical beam (4) enters the analyzer through the glass plate to impinge under an oblique angle of incidence on a first mirror (24) which rotates the plane of polarization in the beam by 45° with respect to the polarizing beam splitter, which then generates two beams partial (202,203) to be eventually directed to photo-detector array (21). The beam analyzer is used in magneto-optical storage system to extract an infor­mation signal and to generate servo control signals for the focus and track positions of the beam. The tilted first mirror may have circular or stripe geometry and be integrally formed within the substrate (20). The multilayer polarizing beam splitter system comprises two stacks of layers separated by an intermediate layer and covered by a thick dielectric layer.

Abstract: The present invention relates to novel ethane derivatives of the formula 1 <IMAGE>  in which R<a> is straight-chain alkyl having 1 to 8 carbon atoms, <IMAGE> or (m = 1 or 2; n = 0 or 1) and R<b> is straight-chain alkyl having 1 to 8 carbon atoms in which, in addition, one or two non-adjacent and in each case non-terminal CH2 group(s) may be replaced by -O-, and to the preparation of the compounds of the formula 1, to liquid-crystalline phases containing compounds of the formula 1, and to their use as components of liquid-crystalline phases. The compounds of the formula 1 have high chemical stability and only low conductivity. They are colourless and readily miscible with all common liquid crystals. Their use in liquid-crystalline phases results in broader mesophase ranges and reduced viscosity. The compounds of the formula 1 according to the invention are thus highly suitable for liquid-crystalline phases for electrooptical display devices, such as, for example, TN cells or guest-host cells.

Abstract: Un circuit de lignes d'abonné (1) est connecté par l'intermédiaire d'une ligne d'abonné (3a, 3b) à un poste téléphonique (2). Lorsque le combiné est décroché, la ligne d'abonné (3a, 3b) est alimentée par un courant ligne (is) à l'aide d'amplificateurs de signaux vocaux (4), lesquels sont produits depuis une source de puissance (VBB). Les amplificateurs de signaux vocaux (4) et leurs amplificateurs d'alimentation (7, 9 et 10) utilisent une puissance inactive importante mis à part la puissance alimentant la ligne d'abonné. Afin de faire baisser cette puissance inactive, le circuit de lignes d'abonné (1) comporte des amplificateurs auxiliaires (5) ayant une puissance inactive basse en vue de l'alimentation de la ligne d'abonné (3a, 3b), lorsque le combiné est raccroché. Lorsqu'un appel est effectué et que le combiné est décroché, le courant de lignes (is) a une valeur relativement importante et lorsque l'appel se termine et que le récepteur est raccroché, le courant de ligne (is) décroît. Cette baisse de courant est détectée par l'intermédiaire d'une résistance (R2) à l'aide d'un circuit de détection en boucle (13), qui envoie un signal (S1) à un circuit de commande (14). Celui-ci envoie ensuite des signaux (S2) et (S3) permettant la connexion des amplificateurs auxiliaires (5) et la déconnexion des amplificateurs de signaux vocaux.

Abstract: A differential pressure transducer of the capacitive type responsive to fluid pressure. The transducer includes a cylindrical body having insulating sections at either end provided with a planar end face and a concave cavity surrounded by an annular rim. The cavities communicate with each other through an internal duct in the body and are filled with a dielectric fluid. Covering each cavity and sealed to the surrounding rim is a diaphragm provided with a movable electrode which cooperates with a fixed electrode on the cavity surface to form a capacitor therewith whose value varies as a function of diaphragm deflection in response to an applied pressure. The contour of each cavity is defined by an inner concave portion whose center is aligned with the longitudinal axis of the body and whose periphery merges with an inflection zone, and an outer portion which curves from the inflection zone toward the rim to merge tangentially therewith to avoid a sharp angle at the inner edge of the rim, the inflection zone being about half the distance from the center to the rim.
