Title: Three phase vacuum switch operating mechanism with anti-bounce device for interrupter contacts
Inventor: KAMP EUGENE L
IPC: H01H33/666
Filed: 1987-08-06
Granted: 1991-09-17
Abstract: ABSTRACT           The velocity of a snap action,  spring loaded vacuum switch closing mechanism is substan-tially reduced by impacting a lever of the mechanism against  a  first  swingable  energy  absorbing  arm which, in turn, pivots to contact a pair of second energy absorbing arms.  The pair of second arms are lightweight relative to the first arm and swing through a greater arc than the latter to permit oscillations to subside in remaining components of the switch before rebounding against the first arm. The swingable arms absorb a significant portion of the kinetic energy of the mechanism during closing of the contacts so that shock waves which are nor-mally  experienced  in  various  components  of  the mechanism cannot combine to a value sufficient to snap the mechanism to an open circuit orientation. The anti-bounce device is particularly useful  for three phase switchgear wherein a single, common mechanism functions to simultaneously close  three pairs of electrical contacts.  The closing mechanism has  a  latching  member  which  cooperates  with  a latching pin to release the mechanism and close the switch when desired.

Title: Pressure activated pump-off control
Inventor: HASTEN JERRY D
IPC: G05D9/12
Filed: 1987-09-01
Granted: 1991-09-03
Abstract: Abstract of the Disclosure A pressure-activated pump-off  control  for  inter-mitting the operation of a low-production well.  A pressure sensor and a series of three timers control the operation of the pump to maximize efficiency.  A first fill-in timer disables  the  pump  for  a  first  time  period  during  which fluids  accumulate  in  the  well.   When  the  fill-in  timer times out, both a second pump-up timer and the pump motor are energized.   If the pressure sensor determines adequate minimum fluid pressure in the tubing,  the pressure switch is  opened,  the  second timer is de-energized,  and control of  the  pump  being  transferred  to  a  third  pump-up  timer in conjunction with the pressure sensor.  When the pressure falls below the desired minimum,  the pressure switch will remain  closed  and  after  a  predetermined  period  of  time corresponding to a desired number of strokes, the pump-off timer times out,  shuts off the pump and re-energizes the fill-in timer for another cycle.

Granted: 1990-10-23
Abstract: SKID-OUT HIGHRISE FIRE ESCAPE DEVICE        ABSTRACT   A  highrise  fire  escape  device  gravity operated and particularly adaptable for use in highrise building and modern skyscraper structures as  an escape  apparatus  from  any  floor  of a building for use in the rescue of an occupant who may  be  trapped  and  prevented  from using  the  conventional stairways  or  elevator  due  to  a natural or man-made disaster such as fire, electrical or power failure, building  collapse  or  personal  injury  of  the occupants, etc. The apparatus or device comprises the combination of a vertical skid track  member attached to the wall of a building with a said which is inserted into a guide channel located in the track.  The skid track is designed  to  be attached  to  either  a new or existing building with access to the skid track being available at the outside of the  building  at  predetermined  locations, such as, building  corners  or  a  plurality of locations intermediate to the corners between the building windows so as  not  to  impede  the  architecture design  of  the  building.  The skid track has a back and guide portion with a plurality of spring loaded or hinged skid track doors which allows the insertion of a skid to which the occupant of a building may be attached.  The skid is so designed to allow its movement down the vertical skid track with the occupant attached, with its rate of descent being controlled by a plurality of descent retarders suitably disposed along the skid tracks entire length. The descent retarder is disposed within the back section of the skid track and partially protrudes into the guide channel of said track. As the skid moves down the guide channel of the skid track it comes into fractional contact with the biased plane frictional surface of the plurality of protruding descent retarders disposed along its vertical axis causing the descent retarder to be displaced in a horizontal direction perpendicular to direction of the skid movement.  The movement of the descent retarders in a horizontal direction is resisted by means just as a plurality of springs interposed between the rear of the descent retarders and the inside the back portion of the skid track.  While the majority of the descent retarders are spaced uniformly along the entire length of the vertical skid track, there are some that are placed in a closer or cluster configuration near the end of the vertical skid track to more greatlyimpede the rate of descent or velocity of the occupant user so as to prevent forceful contact with the ground.  During an emergency, a building occupant may put on a harness of any standard construction and attach it to the skid which can easily be inserted into the guide portion of the vertical skid track throughany of the plurality of track doors disposed along said skid track.

Abstract: PHN 12 010               -??-               29-7-1987 ABSTRACT: Data transmission system comprising smearing filters.     The transmitter (DTR) and the receiver (DRC) of a system for transmitting data signals at a given symbol rate 1/T comprise discrete-time smearing filters (SM and DSM) for combatting the effect of additive pulse-like disturbances (p'(t)) in the transmission channel (TCH). In many cases these disturbances (p'(t)) turn out to have a pronounced bandwidth-limited nature. By utilizing this feature the implementation of the smearing filters (SM and DSM) is simplified and/or their perfor-mance level is improved in that the non-zero values of their impulse responses s(i) and d(j) only occur at the points of grids of the indices i and j recurring with a period of L, where L is an integer greater than 1 and where L is determined substantially by the ratio Lo of the symbol rate 1/T to twice the highest significant fre-quency fm of these disturbances (p'(t)).
