Patent EP-0246275-B1 (EP)
IPC: F25B9/00
Filed: 1986-10-16
Granted: 1991-12-18
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.

Granted: 1994-06-08
Abstract: An electronic read/write or microscope-camera system which can receive and store very low energy optical and equivalent electronic signals on a special optoelectronic tape or medium as varying charge density distributions over the imaged frame. Images are retrieved from the tape or medium by scanning the tape or medium with a focused electron beam which causes the tape or medium to emit secondary electrons as a charge density modulated return beam current. The electrons in the return beam are collected and amplified to develop an electrical signal representative of the image stored on the tape or medium. A method of applying images to and retrieving them from the tape or medium is also disclosed.

Title: Manufacture of flexible intumescent sheet
IPC: D21H11/00
Filed: 1987-04-13
Granted: 1991-04-03
Abstract: Flexible intumescent sheet according to British patent 1 513 808, comprising heat-expandable micaceous mineral, inorganic fibrous material and organic binder, is made on standard board-making machinery incorporating a winding drum, so that a laminar product is obtained, not a monolithic one. The mineral particles in the sheet are thus more uniformly distributed across its thickness, and the product shows less tendency to premature failure in use.

Abstract: Système de fixation des canalisations de gaz d'échappement (6), qui sont agencées dans un espace (2) étanche auxdits gaz et servent à acheminer les gaz de combustion depuis les orifices de sortie de la culasse (9) jusqu'au collecteur d'échappement (5). En raison des sollicitations thermiques élevées que subissent les canalisations d'échappement (6) qui ne sont pas refroidies dans l'espace (2) étanche aux gaz, la fixation est conçue de manière à ce qu'il ne puisse s'exercer aucune contrainte de réaction consécutive à une déformation due à la température. Ainsi, les brides (8) assemblées avec les canalisations d'échappement (6) sont fixées en un seul emplacement périphérique respectivement. Ce mode de fixation en un point permet une dilatation radiale et axiale, sans contrainte de réaction, des canalisations d'échappement (6) soumises à des sollicitations thermiques. Chaque canalisation est vissée, au moyen de vis de fixation (7), dans la région des extrémités côté culasse (9) de préférence sur cette dernière ou sur les parois des éléments constituant l'espace étanche aux gaz d'échappement. La fixation par vis est plus fiable et procure un gain de place.

Abstract: Objects (1) to be stored are fed between two rollers (9, 10) to a belt (2) taken off from a belt coil (5) of a belt reel (6) and wound up therewith (2), forming a storage coil (7), onto a storage reel (3). For the delivery of previously stored objects (1a), the belt (2) is taken off therewith (1a) from the storage coil (7), the objects separate from the belt (2) upon leaving the roller pair (9, 10), the belt (2) being rewound onto the belt coil (b 5). The reels (3, 6) are displaceably mounted; their coils (5, 7) are each supported on a fixedly mounted backing roller (12, 13). For driving the device, the backing rollers (12, 13) can be rotated at coincident peripheral speeds, or respectively one backing roller (12, 13) can be rotated by pulling off the belt (2) from the coil (5, 7) carrying same and the rotation of that backing roller can be transmitted to the other backing roller, or respectively one of the reels (3, 6) can be rotated by pulling off the belt (2) from its coil (5, 7) and the rotation of such reel can be transmitted to the other reel by means of an infinitely variable gear system (42, 43, 46, 47, 51-54, 57-60) in such a way that the peripheral speeds of both coils coincide. In this way, a belt, storage, and delivery speed at constant belt speed is attained which is independent of the respective diameters of the coils.

IPC: G01B9/02
Filed: 1989-04-27
Granted: 1993-02-03
Abstract: The invention is concerned with a method and apparatus for optically detecting transient motion from a scattering surface (14). A laser beam (10) having a predetermined frequency is directed onto such a surface (14) to thereby scatter the laser beam and produce a scattered laser beam (16) defining an optical wavefront and having an optical spectrum with a central peak at the laser frequency (FL) and a sideband on either side of the central peak. The laser beam (16) scattered by the surface (14) is caused to interfere with a reference beam (22) derived from the scattered laser beam (16) and having an optical wavefront substantially matching the wavefront of the scattered beam and an optical spectrum with a single peak at the laser frequency (FL) and no sidebands, to obtain an optical signal which is detected and converted into an electrical signal representative of the transient motion. The optical detection technique according to the invention has a broad frequency bandwidth and a large étendue providing greater sensitivity of detection, and is particularly useful for detecting small surface deformations of a material or workpiece subjected to ultrasonic energy.

Abstract: A clutch assembly for an accumulating roller conveyor comprises a sprocket (8) which is drivably engageable with a conveyor drive chain (6). The assembly also includes a drive shaft (3) which is drivably engageable with a roller (2) of the conveyor. A first clutch plate is constituted by a surface of the sprocket (8), and a second clutch plate is constituted by a retaining ring (11).

The first and second clutch plates are made of an elastically-deformable plastics material. The sprocket (8) is rotatably mounted on a shaft sleeve (7) by means of an angular contact bearing (9), the first and second clutch plates being generally annular and surrounding the shaft sleeve. The shaft sleeve (7) is fixed to, and rotatable with, the retaining ring (11), and the arrangement is such that the rolling elements (10a) elastically deform the surfaces of the first and second clutch plates, whereby torque can be transmitted from the first clutch plate to the second clutch plate.
