Filed: 1995-03-08
Abstract: A watthour meter mounting apparatus, such as a socket, socket adapter and the like, has a safety shield completely enclosing the jaw contacts of the apparatus. Slots are formed in the safety shield to allow the insertion of a watthour meter blade terminal therethrough into connection with the jaw contacts.  In one embodiment, a socket adapter housing includes front and back plates which are joined together and form a cavity therebetween in which the jaw terminals and the electrical conductors are disposed.  Raised receptacles formed in the first plate loosely receive the jaw contacts mounted on one end of the conductors.  In another embodiment, an insulating housing is mounted over the jaw contacts in a socket or socket adapter, with slots formed in the housing to allow the insertion of a watthour meter blade terminal therethrough into a jaw contact disposed within the housing.  The housing may be formed with one large cavity surrounding all of the jaw terminals or a plurality of separate receptacles, each surrounding at least one jaw contact.  The conductors may be formed of rigid bus bar for increased current carrying capability.  Each jaw contact can be formed of separate contact clips biased toward each other by separate spring clips riveted to one end of each conductor.  A terminal slidably receives the other end of each conductor as well as a line/load external conductor.

Abstract: Adaptive compressive gain and level de-pendent spectral shaping circuitry for a hearing aid include a microphone to produce an input signal and a plurality of channels connected to a common circuit output (102). Each channel has a preset frequency response. Each channel includes a filter (F1, F2, F3, F4) with a preset frequency response to receive the input signal (12) and to produce a filtered signal, a channel amplifier to amplify the filtered signal to pro-duce a channel output signal, a threshold regis-ter (34) to establish a channel threshold level, and a gain circuit (24). The gain circuit in-creases the gain of the channel amplifier when the channel output signal falls below the chan-nel threshold level and decreases the gain of the channel amplifier when the channel output signal rises above the channel threshold level. A transducer produces sound in response to the signal passed by the common circuit output.

Abstract: A barrier arrangement for use in a multiple-phase padmounted  switchgear  includes  a  pair  of  insulated upper  and  lower  barrier  panels  mounted  in  spaced vertical tandem and stationary relation one above the other  so as  to  define  a  gap  therebetween  and  an insulated intermediate barrier panel disposed adjacent to the gap between the upper and lower barrier panels. The barrier panels are disposed within an enclosure of the  switchgear  between  the  pairs  of  multi-phase switchgear assemblies.  The intermediate barrier panel is mounted to the upper barrier panel so as to undergo sliding movement between lowered and raised positions relative  to  the  lower  barrier  panel  so  as  to respectively open and close the gap between the upper and lower barrier panels in response to insertion and withdrawal  of  a  transversely  disposed  additional barrier  panel  through  the  gap.    The  intermediate barrier panel has a forward edge which includes a lower portion  extending  downwardly  and  rearwardly  in  an declining oblique relation to the direction of movement of  the  intermediate  panel  between  the  lowered  and raised  positions  such  that  engagement  of  the transversely disposed additional barrier panel with the lower portion of the  forward edge causes a camming action thereon which lifts the  intermediate barrier panel from the lowered position to the raised position.

Abstract: An autonomous bomb damage assessment system (10) that is piggybacked to a bomb (11) to provide imagery of a bombed area immediately after bomb delivery. The bomb damage assessment system (10) comprises a housing (20) that is releasably secured to the bomb (11). An imaging system (13) is disposed at one end of the housing (20) and a folded inflatable balloon (18) is disposed at the other end of the housing (20). An inflation device (17) is provided for inflating the balloon (18) with a lighter-than-air gas such as helium. A proximity fuze (14) is used to sense the location of the ground, for causing the system (10) to be ejected awayfrom the bomb (11) shortly before bomb impact, and for causing the inflation device to inflate the balloon (18). A data link (16) is disposed in the housing (20) for transmitting images derived from the imaging system (13) to a remote location. The present invention provides imagery of a bombed area immediately after bomb delivery. The lighter than air characteristic of the system (10) allows a dwell time over the bombed area so debris and dust can settle. Fine resolution and short range provide detailed images. Television or infrared cameras may be used as theimaging system (13) to permit for day or night missions. The data link (16) allows images to be recorded in an aircraft sent via satellite to a recording center. The images may then be flown back to a base or relayed from the aircraft to the baseusing another data link. Bomb damage assessment may be performed at the base within minutes after an attack.
