Patent CA-2123947-A1 (CA)
Inventor: TAKADA HIDEAKI
IPC: F01N13/12
Filed: 1994-05-19
Abstract: In a propeller for a boat,  a plurality of recesses and   a   plurality   of   land   portions   are   arranged circumferentially  alternately around  an outer  Periphery of a propeller boss which is fitted over and connected to a propeller shaft. A boss of each of propeller blades and each of blade shafts disposed parallel to an axis of the propeller boss to rotatably support such propeller blade are accommodated in each of the recesses, and each of the land  portions  is  provided  with  an  exhaust  passage extending axially through the land portion to permit an exhaust outlet  in a body of a propelling device  to be opened at a rear end face of the propeller boss. Thus, it is possible to discharge an exhaust gas  from an engine through the inside of the propeller boss  into water.  In addition,  an extension shaft  is  spline-fitted over  and detachably secured to a Protrusion of the propeller shaft projecting  rearwardly  of  the  body  of  the  propelling device  to  extend  rearwardly  from  a  rear  end of  the propeller  shaft.  The propeller  boss is  fitted over  the extension shaft over its substantially entire length. The propeller blade is mounted around an outer periphery of a front half of the propeller boss, 90 that the propeller diameter  or  pitch angle  can be varied,  while  a  damper rubber  is  baked  to  an outer  peripheral  surface  of  the extension shaft and press-fitted  into an annular  recess which is defined around an inner periphery of a rear half of  the  propeller  boss.  Thus,  a  variable-thrust  type propeller with a torque limiting device can be attached to a relatively short propeller  shaft used for  a usual propeller.

Abstract: MECHANISM FOR CONTROLLING THE POSITION OF LEVERS   ABSTRACT OF THE DISCLOSURE         A mechanism for controlling the pivotal positioning of a hydraulic control lever on tractors is disclosed wherein a gated plate is affixed to the control lever to be pivotally moveable therewith into selective engagement with a lockout pin projecting outwardly from a pivoted actuating lever.  The gated plate has first and second gates for selectively receiving the lockout pin when in a first position to restrict the pivotal movement of said control lever in preselected manners.  The gated plate further includes a stop engageable with the lockout pin when in a second position to prevent the control lever from being placed in a float position.  A third selectable position of said actuating lever places the lockout pin out of engagement with said gated plate to allow an unrestricted freedom of movement of the control lever.  The pivoted control lever and the pivoted actuating lever project outwardly through a control panel for manipulation thereof.

Title: Incandescent lighting system with infrared sensing device for sensing the presence of an intruder
Inventor: OSTEEN MITCHELL M
IPC: G08B13/19
Filed: 1994-11-10
Abstract: This  lighting system comprises  an  incandescent  lamp energizable from a source of a.c. voltage and an infrared sensing device sensitive to the presence near said device of an intruder for producing an output signal in response to such presence.  Means responsive to the output signal causes the power supplied from the source to the lamp to be higher when the output signal from the sensing device  indicates the presence of an intruder than is the power supplied from the source when the sensing device indicates there is no intruder present. Means effective during periods of darkness causes the incandescent lamp to be energized from the a.c. source at a relatively low power level compared to the full-brightness power level when the sensing device indicates no intruder is present.

Abstract: This invention relates to a process for bonding a vehicle window to a vehicle flange comprising the sequential steps of: a) applying a liquid masking composition to a vehicle flange, b) painting the vehicle, and drying or curing the liquid masking composition sufficiently to form a strippable mask; c) removing the mask from the flange; and d) adhesively bonding the vehicle window to the vehicle flange. Such a masking process advantageously eliminates the need for the use of solvent-based primers normally used to prime a painted vehicle flange, and provides a mask which is more easily applied and removed from the flange than masking means which initially comprise a solid substance.

Title: Method and a scheduler for controlling when a server provides service with rate control to an entity
Inventor: BENNETT JON C R
IPC: G06F9/48
Filed: 1995-06-05
Abstract: The present invention pertains to a method for scheduling when a server provides service to entities. The method comprises the steps of identifying when a first entity requests service from the server. Next there is the step of providing service to an entity, such as a first entity or a second entity, as a function of virtual time. The present invention pertains to a scheduler for controlling when a server provides service to entities. The scheduler comprises a memory having times which are a function of when entities request service from the server. The scheduler is also comprised of a virtual clock that keeps track of time. The scheduler is also comprised of a controller which causes an entity to receive service from the server as a function of virtual time.      The present invention pertains to a scheduler for scheduling when N entities each of which has a weight w, where N is an integer > 1 and w is a real number, are served by a server. The scheduler is comprised of a starting time memory having starting times s i when the N entities request service, where 1 ~ i ~ N and is an integer, and s i is the time at which the i'th entity may next get service from the server. The scheduler is also comprised of a finishing time memory having f i finishing times f i when the N entities should be serviced, where f i is the time by which the i'th entity should be serviced by the server. The scheduler is also comprised of a virtual clock that keeps track of time V k where k ~ 0 and is an integer and V k=MAX((V k-1+P) + (1*X) + ((1/AW)*T), (s smin*Y) + ((f Fmin - S smin)*Z)) where(~P~+~T~+~X~)*(~Y~+~Z~)> 0 where S Smin is the earliest start time s i of when an entity requests service from the server; f Fmin is the earliest finish time of an entity waiting for service from the server; V k-1 is the virtual time when the server last served an entity; A W = sum over all entities currently asking for service of w i, where w i is the i'th entity's weight; and X, T, Y and Z are real numbers. If rate control is utilized, then Y=Z=0 and the last line of the equation is not applicable, or in other words, V k = V k-l +1.

Title: Potentiometric evaluation of substrate oxidation and coating porosity
Inventor: TENCH MORGAN
IPC: G01N27/416
Filed: 1995-07-24
Abstract: A fast, nondestructive, and easy to perform method of Potentiometric Evaluation of Substrate Oxidation ("PESO") is provided. A coated part to be analyzed is placed in contact with an electrolytic solution having a pH adjusted to provide an optimum oxide dissolution rate. The open circuit potential of the part is monitored as the substrate oxide dissolves in the electrolytic solution. The voltage typically changes as a function of time during oxide dissolution. When oxide dissolution is complete, the voltage reaches a steady value associated with active dissolution of the substrate metal and reduction processes on the coating. The electrolytic solution can be flowed or agitated to reduce concentration polarization, provide more meaningful voltage measurements, and minimize the time required for analysis.  The time required to reach a steady-state voltage provides a measure of the amount of substrate oxide within pores in the coating. The final steady-state voltage level provides a measure of the relative areas of the coating and the exposed substrate, which relates to the porosity of the coating. The method is useful for evaluating the quality of coated parts by providing a quantitative measure of both substrate oxidation and coating porosity.
