Patent CA-2019513-A1 (CA)
Title: Catheter holder
Inventor: PLASS RONALD A
IPC: A61M25/02
Filed: 1990-06-21
Abstract: A catheter holder has a pad of medical grade adhesive material having one surface for attachment to the skin of a wearer, and a pair of tapes secured to and extending from the other surface of the pad.      A multiple use adhesive is placed on a surface of at least one tape which surface faces generally towards the other tape. With such an arrangement, the two tapes can be stuck together to enclose the catheter and at the same time the tape carrying the adhesive sticks to the adjacent wall of the catheter so preventing logitudinal movement of the catheter relative to the pad.

Title: Flail chain unloader for particulate material
Inventor: LEPLEY JAMES W
IPC: B01F7/00
Filed: 1990-07-18
Abstract: FLAIL CHAIN UNLOADER FOR PARTICULATE MATERIAL           Abstract of the Disclosure A flail chain unloader for discharging par-ticulate material from a lower outlet of an upright storage vessel includes a rotating shaft extending upwardly of the central portion of the vessel above the outlet and flail chains secured to the shaft at different levels thereon to rotate with the shaft and loosen the particulate materials in the vessel to flow downwardly for discharge through the lower outlet. One or more upper flail chains are secured adjacent an upper level portion of the shaft and have outer ends movable in a generally circular path closely adjacent the inside wall surface of the vessel for loosening the material adjacent the vessel wall.  At least one set of intermediate flail chains of a rela-tively short length is provided at spaced apart lower levels below the upper flail chains in order to dig out the material in the central portion of the vessel around the shaft.  These short length chains are de-signed to minimize entanglement with the upper longer flail chains when the unloader is starting up from rest and the chains are hanging downwardly around the shaft before sufficient centrifugal force is attained for the chains to swing outwardly toward a horizontal orbit around the vessel.
Patent CA-2024305-A1 (CA)
Inventor: FAREL RICHARD A
IPC: H04M3/00
Filed: 1990-08-30
Abstract: Abstract This invention relates to a method and apparatus for throttling request messages to an overloaded database and for throttling overload traffic to a particular destination. The database sends a gap value to the sources of messages or traffic; following any message or call to the destination, no messages will be sent or calls to the destination completed for one gap interval. In a departure from the prior art, the gap interval, a function of the number of request messages flushed or overload calls to the destination is not recurrently calculated anew, but is instead recurrently adjusted from its previous value. Advantageously, this arrangement permits a relatively stable value of the gap to be maintained and reduces overhead for preliminary processing of request messages that cannot be handled.

Inventor: THIMON JACQUES
IPC: B65B41/16
Filed: 1990-09-06
Abstract: A  process  for  using  a  carriage  for unwinding packaging film which comprises a stand and a supporting  shaft for  a film reel.  A device is provided with rollers having axes parallel to that of the supporting shaft.  The carriage is intended to be incorporated  in  a packaging machine.   The process includes an initial phase for associating a reel with a  supporting  shaft  and  a  subsequent  phase  for positioning  the  film  web  in  the  roller  device comprising two upstream and downstream main rollers defining between them a passage and designed to pivot about their axes in opposite directions.  Further, a phase for unwinding the film for the packaging of the load  is  provided  wherein,   during  the  phase  of positioning the film web,  the starting point is an initial  state in which  the upstream and downstream guide  rollers  are  relatively  displaced  from their final  operational  location  to  a temporary  initial positioning location. Also in an initial introduction phase,   an  initial  end of  the film is introduced between the upstream main roller and guide roller and in  the  direction  of  the  downstream  main  roller. Further,  in a subsequent running phase, the upstream and downstream main rollers are pivoted about their axes,  and a particular length of film is made to run in the direction of its introduction into the device. In  a  final  positioning phase,   as  a result  of  a relative  displacement  the  upstream  and downstream guide rollers are brought from their initial location to their final operational location,  the effect of this being to bend the film,  at the same time laying it against the upstream and downstream main rollers.
