Title: Dispositivo holográfico para controlar la luminosidad y aumentar la eficiencia energética en edificios
Inventor: RODRIGUEZ SAN SEGUNDO HUGO-JOSE
IPC: G02B5/32
Filed: 2015-02-06
Granted: 2017-08-10
Abstract: Dispositivo holográfico para controlar la luminosidad y aumentar la eficiencia energética en edificios.#Se propone un dispositivo holográfico para su aplicación en ventanas. La invención actúa como agente pasivo de mejora de la eficiencia energética de un edificio si el holograma (1) está diseñado para que difracte parte de la radiación incidente por reflexión (7) solamente cuando el sol (5) incide con ángulos muy inclinados en verano. En invierno el sol (6) incide con ángulos menores, por lo que el holograma (1) no actúa y toda la radiación (8) se transmite al interior. La invención también actúa como control de luminosidad si en verano el holograma (1) opera dentro del espectro visible y su eficiencia de difracción se regula permitiendo que una parte de la radiación se transmita (8) y otra se difracte (7).

Title: Oven for producing coke
Inventor: SEEBERG H
IPC: C10B39/02
Filed: 1978-02-24
Granted: 1981-05-25
Abstract: A coke oven of the inclined chamber type has a greater throughput capacity, compared with conventional types, combined with an optimum energy utilisation.  It ensures a satisfactory and troublefree coking operation.  The width of an oven chamber(2) in the upper part(5) near the oven ceiling(3) is designed 1.2 to 1.5 times greater than the chamber width in the lower part(6) near the sole(4).  Practical tests have proved that this raised the throughput by 5%, reduces the shrinkage-induced lowering of the briquette level and reduces the temp. of the gas collection space above the coke and the temp. of the oven ceiling.

Title: Variable speed resistive network for a pneumatic servo assembly of an electro-pneumatic converter
Inventor: ROBERTSON JOHN W JR
IPC: F15B5/00
Filed: 1985-03-27
Granted: 1990-05-04
Abstract: The converter includes a reversible dc servo motor with a pair of terminals connected to a pair of lines. The lines are selectively connectable to a common terminal of a power supply. The power terminal of the power supply is connected over a variable resistor to a terminal connecting the lines. Selectively connecting one of the lines to the common terminal causes electrical power to pass through the motor and one for an opposite direction to turn the motor shaft in a selected direction of rotation. The speed of rotation is determined by the position of the variable resistor. The The motor shaft is used in conjunction with a cam that is associated with a nozzle supplied with pressurised gas over a bellows. The nozzle is moved closer or further away from the cam edge as the bellows expands or contracts. A line connected upstream of the bellows provides gas at a selected pressure which is proportional to the position of the cam.

Title: Method and apparatus for processing a video signal so as to prohibit the making of acceptable video tape recording thereof
Inventor: RYAN JOHN O
IPC: H04N5/91
Filed: 1986-04-15
Granted: 1993-07-16
Abstract: A video signal is modified so that a television receiver will still provide a normal color picture from the modified video signal while a videotape recording of the modified video signal produces generally unacceptable pictures. This invention relies on the fact that typical videocassette recorder automatic gain control systems cannot distinguish between the normal sync pulses (including equalizing or broad pulses) of a conventional video signal and added pseudo-sync pulses. Pseudo-sync pulses are defined here as any other pulses which extend down to a normal sync tip level and which have a duration of at least 0.5 microseconds. A plurality of such pseudo-sync pulses is added to the conventional video signal during the vertical blanking interval, and each of such pseudo-sync pulses is followed by a positive pulse of suitable amplitude and duration. As a result, the automatic gain control system in a videotape recorder will make a false measurement of video level which causes an improper recording of the video signal. The result is unacceptable picture quality during playback. This approach utilizes positive-going pulses which occur at a time not ordinarily used for black-level restoration in typical television receivers, and therefore does not give rise to black level depression in such typical television sets.

Inventor: THOMPSON HUGH A
IPC: A61F13/49

Granted: 1994-02-02
Abstract: @ The present invention pertains, in a particularly preferred embodiment, to an apertured, macroscopically expanded, resilient three-dimensional polymeric web which is believed to have particular utility as a breatheable barrier for a disposable bandage such as a diaper. The web preferably comprises a deeply drawn three-dimensional structure containing a multiplicity of debossments of macroscopic (i.e., visibly perceivable by the normal human eye at a perpendicular distance of about one foot) cross-section, each of said debossments originating as an aperture in a first surface of the web and having a continuously interconnected side wall extending in the direction of a second, remotely located parallel surface of the web. The side wall of each debossment terminates to form an end wall in the second surface of the web. The end wall includes a multiplicity of apertures, each of said apertures being sized and shaped to independently support an aqueous fluid meniscus. The smaller apertures in each end wall are so spaced relative to all adjacent apertures in the end wall that the aqueous fluid menisci supported in the apertures do not contact one another or the side wall. In a disposable absorbent bandage context, the second surface of the web containing the end walls with small apertures therein is placed in contact with the absorbent core portion of the bandage and the surface of the web in which the debossments originate is oriented so as to contact the wearer's outer garments in use.
