Title: Data processor with window based display means for parent-child tasks
Inventor: VAUGHTON MATTHEW K
IPC: G06F3/0481
Filed: 1990-07-05
Abstract: A  data  processing  system  having  a  window  based display  and  a  processor  executing  a  plurality  of interleaved data processing tasks each having one or more associated display windows, wherein execution of a first task   may   trigger   execution   of   a   second   task, characterised in that when execution of said first task triggers execution of said second task,  said processor uses data identifying said first task's display window(s) to  control  display  of  said  second  task's  display window(s)  so as to be connected to and move with said first task's display window(s). The disclosed system has the advantage over the prior art in that it provides a visual connection between the windows of the first and second  tasks  which  makes  the  display  easier  to understand.

Title: Acoustic absorber, and method of manufacture thereof
Inventor: DIDUCK MURRAY F
IPC: E04B1/84
Filed: 1990-07-09
Abstract: A sound absorber has a column shape defined by a hollow,  substantially  cylindrical  wire  frame with  a filler of uniformly distributed fused parallel filaments having high surface area to mass ratio, such as bloomed cellulose acetate.  The sound absorber gives efficient absorption in the articulation frequency range.       A method of manufacture of the sound absorber includes determining the sound response of an acoustic environment,  determining the reciprocal of the sound response of that environment, and matching the absorption characteristics of the sound absorber to the reciprocal of the sound response.       Each  sound  absorber  has  a  linear  absorption spectrum above the center frequency so that clusters of the sound absorbers exhibit a similar spectrum.

Title: Retractable boom stop
Inventor: ASCHE JAMES E
IPC: E02F3/38
Filed: 1990-09-10
Abstract: A retractable boom stop includes a channel shaped stop member mounted for pivotal and rectilinear movement relative to the boom arm of a skid steer vehicle. The stop member is movable between an inoperative position adjacent the boom arm and an operative position interposed between the boom arm and lift cylinder. In the operative position the stop member prevents an extensible rod of the lift cylinder from retracting to lower the boom arm. The stop member is  secured in the inoperative and operative positions by a retaining pin. A tension spring carried by the stop member and releasably securable to the boom arm automatically retracts the stop member out of the operative position to allow the lift cylinder to be retracted.

Abstract: A small diameter dilatation catheter for coronary angioplasty is achieved by providing first and second elongated flexible, thin-wall tubes, each having one or more reinforcing wires encapsulated in the walls thereof and dimensioned such that the second tube may be coaxially disposed within the lumen of the first tube.  The preferred material from which the two tubes are  fabricated  is  polyimide.    The  longitudinally extending  reinforcing wires  provide  the  requisite "pushability"   characteristics   required   by   PTCA dilatation catheters.  The balloon or inflation member has its proximal end bonded to the outer surface of the outer tube and its distal end bonded to the outer surface of the tube.   Inflation fluid then may be perfused between the I.D. of the outer tube and the O.D. of the inner tube.

Title: Ocean wave air compressor
Inventor: MOROCUTTI GIANCARLO
IPC: F03B13/14

Patent CA-2028164-A1 (CA)
Title: Heat-curable silicone compositions having improved bath life
Inventor: CHUNG KYUHA
IPC: C09J7/02
Filed: 1990-10-22
Abstract: A curable organosilicon composition comprises a component having silicon-bonded hydrogen atoms, a component having silicon-bonded radicals reactive therewith, a curing catalyst, a catalyst-inhibitor and a bath life extender. The use of certain compounds, which are ineffective as a bath life extender in the absence of a catalyst inhibitor, effectively extend the room temperature bath life of a silicone coating composition containing a catalyst inhibitor.      Being a substantial non-inhibitor for the catalyst the bath life extender component does not affect the cure time and/or cure temperature of the composition.  This discovery has permitted the preparation of curable coating compositions which have a long bath life at room temperature and a rapid cure time at elevated temperatures which does not drift to longer intervals as the coating compositions ages over a typical production run.      The room temperature cure times of the organo-polysiloxane coating compositions of this invention are adequately long and their cure times at elevated temperature are advantageously brief, so that they are useful in fast-paced coating operations, such as adhesive release coating operations wherein the cured coating is further coated with an adhesive in-line, i.e., immediately after being cured.
