Abstract: A system for sensing information at a plurality remote, typically hazardous, locations and transmitting the sensed information to a main monitoring center.  Remote portable "attendants" that take the place of a human safety monitor are carried by persons at the remote locations.  The portable attendants produce an audible and/or visual warning to the operator at selected times.   If the operator does not acknowledge the warning within a selected time, an alarm signal is sounded and is sent to the main central by radio for processing in a central processing unit (CPU).   The CPU directs an appropriate safety response and may open a voice radio circuit between central operators and the remote monitor location.  A switch is provided so that the remote operator can manually trigger the alarm.  A gas sensor which can detect and measure the level of a selected gas may be included at the remote monitor, with the capability of sounding an alarm at the portable attendant and transmitting an alarm signal to the CPU identifying the gas and indicating the level.  Sensors for similarly monitoring effectiveness of a ventilation system at the remote location can be provided.  Finally, the arrangement for receiving and transmitting radio signals from the central monitor may include a plurality of spaced spread spectrum radio frequency transmitter/receivers to permit the location of the portable remote attendants to be rapidly determined.

Abstract: A DOUBLE-ACTING ACCELERATOR FOR USE WITH HYDRAULIC DRILLING JARS       ABSTRACT        A double acting accelerator (1) includes a mandrel (2) arranged in a housing (3) for sliding longitudinal movement. A pair of pistons (89), (111) are positioned radially between the housing (3) and mandrel (2) to form a substantially sealed chamber (88) longitudinally therebetween. Movement of the mandrel (2) in a first direction urges the first piston (89) toward the second piston (111), thereby greatly increasing the pressure of fluid in the chamber (88). Movement of the mandrel (2) in a second, opposite direction urges the second piston (111) toward the first piston (89) to, likewise, greatly increase the pressure of fluid in the chamber (88). Thus, a large amount of energy is stored in the accelerator (1) independent of the relative direction of movement of the mandrel (2) and housing (3).

Abstract: Multishaped beam direct radiating array antenna, essentially constituted (Fig. 1) with a network on which high power beam forming sub-networks (3), are disposed; said network (2) is interposed between radiating elements (1) and RF power amplifiers (4). This antenna is in addition constituted with a traditional network in which power combiners (5), phase shifters (6) and interconnection lines (11) are at their turn positioned. The most significant feature essentially resides in the fact that, with the help of a high power beam forming network (2), suitably designed, the correct amplitude and phase values, at radiating elements (1) level, may be achieved without differentiating the RF power amplifier (4) output levels, thus keeping its efficiency as high as possible. One of the advantages this configuration presents is the possibility to utilise only one antenna in comparison of the previous techniques in which the same results were obtained utilising many radiating panels.      Though, this antenna configuration offers more simplicity, lower costs and a good reliability. The invention lies in the field of multishaped beam, antennas and finds its application specially in the space communications.

The data represents a plurality of frames which correspond to a plurality of groups of pictures (GOPs), in which each of the GOPs includes different types of pictures including intraframe predictively (I) encoded and interframe predictively (P) encoded pictures. The compressed data is read from the recording medium, and the type of pictures corresponding to the read data is determined. The read image data is decoded and supplied to a display device. When special processing (such as, random accessing) is performed, image data may not be properly decoded during an initial period. During this time period, an auxiliary signal may be supplied to the display device. Such supply of the auxilliary signal continues until image data corresponding to an intraframe predictively encoded (I) picture and either another intraframe predictively encoded (I) picture or an interframe predictively encoded (P) picture are detected, whereupon the respective image data is properly decoded by utilizing the image data corresponding to the detected P and/or I pictures and supplied to the display device instead of the auxiliary signal.
