Abstract: An impact absorbing protective cap includes a rigid shell which fits on the head of the wearer.  The shell is generally hemispherical  in shape and terminates in a peripheral edge which defines an open space.  An attenuator band is mounted to the inner surface of the shell generally at the peripheral edge for distributing lateral impact forces striking the outer surface of the shell.  The attenuator band is made of flexible hard material and is in corrugated form with a series of undulations alternately disposed toward and away from the inner surface of the shell.

Granted: 1996-08-06
Abstract: An improved tubing rotator is mounted to the casing bowl of a well, for rotating a tubing string extending down the well.          A swivel dognut assembly is provided, comprising inner and outer sleeves.   The tubing string is suspended from the inner sleeve which is rotatably supported from the stationary outer sleeve.  The outer sleeve is adapted to be suspended from the tapered inner surface of the casing bowl,  and is restrained from vertically upwards displacement by holddown screws.   The outer sleeve is almost entirely contained or recessed within the casing bowl.  A housing is bolted onto the casing flange.  A pair of worms extend through the housing and driveably engage a ring gear associated with the inner sleeve.   Because the sleeves are seated in the casing bowl, a compact rotator assembly is obtained.  In addition, the tubing rotator is designed to permit the housing to be removed and a blowout preventer ("BOP") to be installed for well servicing while continuing to maintain a seal between the swivel dognut assembly  and  the  casing  bowl,  thus  sealing  the  annulus  and preventing an otherwise possible blowout.   The  swivel  dognut assembly can subsequently be removed with the tubing string through the BOP.

Title: Photoelectric smoke detector
Inventor: RATTMAN WILLIAM J
IPC: G08B17/107
Filed: 1994-05-09
Granted: 1999-03-16
Abstract: The present invention provides for a photoelectric smoke detector comprising a case having mounted therein a circuit board and a smoke detection chamber.  The smoke detection chamber has side walls with openings provided therein for ingress and egress of smoke particles, a top and a bottom.  A photoemitting diode is mounted in a mounting arrangement in the side wall of the smoke detection chamber so that a light beam from the photoemitting diode is transmitted across the smoke detection chamber without directly impinging upon either the top or the bottom surfaces.  The bottom of the smoke detection chamber has an opening therein with a shielding arrangement thereabout open to the chamber, the opening and shielding arrangement being located between the centerline of the smoke detection chamber and the mounting arrangement in the side wall of the chamber.  The circuit board is mounted to overlie the bottom surface and includes a photodiode detector mounted directly thereon and positioned generally in the opening so that it views into the smoke detection chamber through the opening and through the shielding arrangement, the shielding arrangement shielding the photodiode detector from incident light which may be present in the smoke detector chamber while providing for a diverging field of view of the photodiode detector. The diverging field of view of the photodiode detector intersects the light beam of the photoemitting diode to define a detection volume contained within the smoke detection chamber located close to the photoemitting diode and the photodiode detector and spaced from the surfaces of the smoke detection chamber to minimize the effect on the photodiode detector of light from the photoemitting diode which is reflected exterior to the detection volume.

Abstract: The present invention relates to a system and method for controlling fluctuations in a power distribution system.  The system includes a system information input unit that takes in system information and a system state determining unit that determines states of the system.  A component operation state determination unit is provided that determines operation states of system stabilizing components.  A control plan deciding unit decides a control plan of the system in consideration of operation states of the system and the system stabilizing components.  In deciding the control plan, a swing mode analysing unit firstly analyzes the swing mode at each location of the system on the basis of waveforms of time domain response simulations.  A control allotment setting unit then determines control allotment for each of the system stabilizing components based on the mode analysis and a control parameter setting unit control sets the control parameters of each of the system stabilizing components.  If plural control plans are obtained, the optimal one is selected based on eigenvalues of the dynamics of the system or by evaluating time domain system responses by simulation method.          The decided control plan is output to the system stabilizing components by a control plan output unit.

Granted: 1998-12-29
Abstract: This invention improves the frequency acquisition range and the resistance to multipath interference. In a digital signal transmission system using OFDM, on the transmission side, some or all of a plurality of equidistant carrier positions are treated as reference carrier positions. The actual transmitted carriers are arranged in a predetermined pattern non-equidistant to the frequency carrier positions to form an OFDM symbol. This OFDM symbol is periodically transmitted as frequency reference symbols. On the reception side, the carrier arrangement pattern of the frequency reference symbols is detected, a carrier frequency offset is detected from the detected pattern offset, and the carrier frequency is compensated based on the frequency offset.

Abstract: Un dispositif de remplissage de récipients stériles définit une zone longue mais étroite comportant plusieurs postes fonctionnels. Une paroi verticale de forme allongée, montée sur un châssis de forme également allongée, définit avec une armoire d'enceinte une zone stérile. Les différents postes fonctionnels sont disposés en série longitudinalement dans la zone stérile où un convoyeur à récipients transporte les récipients de poste en poste. L'ensemble convoyeur, disposé verticalement, est constitué d'une bande sans fin montée sur des roues tournant sur des axes horizontaux. Chacun des postes fonctionnels comporte une partie fonctionnelle située en zone stérile. Tous les actionneurs de chacun des postes fonctionnels ainsi que tous ceux du convoyeur longitudinal sont situés hors de la zone stérile. A travers la paroi verticale, des éléments raccords mettent en relation fonctionnelle avec son poste opérationnel chacun des actionneurs situés à l'extérieur de la zone stérile. La disposition verticale de l'ensemble convoyeur et l'implantation des différents actionneurs à l'extérieur de la zone stérile selon un plan "côte à côte", permet de réduire de façon notoire la largeur effective de la zone stérile. L'accès à la zone stérile, ainsi que son séchage après une opération de lavage, en sont donc facilités. En outre, les dimensions réduites de la zone stérile en font un appareil plus facile à fabriquer et à maintenir en état stérile.
