Patent CA-1052893-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE A multiple flashlamp array has a plurality of flashlamps which are arranged to be fired individually and in sequence.  The array includes a plurality of static solid switching devices, each device being located adjacent an associated flashlamp.  Actuation of a switching device by radiant energy generated during flashing of the adjacent flashlamp causes the next-to-flash lamp to be connected into the circuit.  Initially, the switching devices have a high electrical resistance ("off" condition).  After actuation by radiation, they undergo chemical conversion and have a low electrical resistance ("on" condition).  The switches are prepared from compositions which impart improved shelf life under conditions of relatively high humidity at above normal ambient temperature.

Abstract: Abstract of Disclosure Pumping apparatus for conveying animal waste from a livestock housing to a remote storage area includes a hopper with one downwardly inclined hopper surface with the other surfaces of the hopper being vertical and in which the inclined surface supports an agitating plate which oscillates and mini-mizes bridging of straw across the hopper walls.  The agitating plate is oscillated by a motor driven crank.  Spray tubes arranged around the vertical and inclined walls provide a water curtain to further minimize sticking and bridging of the manure in the hopper.  Other features of the invention include a reduc-ing cone to reduce the diameter of the pumping chamber to that of the discharge pipe with the reducing cone provided with check valves to prevent back flow of manure from the storage area through the pump and into the livestock housing when the pump is not in use.  A circuit is provided to stop the ram in a down position in the pumping chamber when the pump is not in use to further prevent backflow into the livestock facility.
