Patent CA-1289821-C (CA)
Inventor: OGURA MICHIHITO
IPC: B63H1/28
Filed: 1987-07-30
Granted: 1991-10-01
Abstract: ABSTRACT OF THE DISCLOSURE           A screw propeller boss cap with fins is provided to increase the propeller characteristics particularly the propeller efficiency.  Owing to the fins on the boss cap, the water stream rearward of the boss cap is guided to a direction of reducing the generation of the hub vortex and on that score the propeller efficiency is increased.  The fins should satisfy the conditions as follows:    (i)  they are of the same number for each propeller blade, (ii)  they have the inclination "Alpha" from -20° to +30° against the geometric pitch angle "Epsilon" of a propeller blade root, that is, -20° ? "Alpha" -"Epsilon" ? 30°, and the leading edge located between the adjacent propeller blade roots, and (iii)  they have the maximum diameter larger than the diameter of the cap-mounting end of the boss and not larger than 33% of the propeller diameter.          Thus the propeller characteristics can be greatly improved by a rather simple and economically practicable means.

Title: Method and apparatus for utilizing waste heat in a combustion system
Inventor: PRICE RICHARD C
IPC: F23L15/04
Filed: 1987-11-16
Granted: 1992-03-24
Abstract: Abstract of the Disclosure An improved method and apparatus for recovery of waste heat of the type having a first heat exchanger which transfers heat to a working fluid and a second heat exchanger which transfers heat from the working fluid is disclosed.  The improvement comprises the provision of at least one storage tank for the working fluid having a volume calculated by the flow rate of the working fluid multiplied by a time difference between the time in which the combustion chamber has its peak fuel requirement and a next subsequent time at which a maximum amount of waste heat is available to the combustion chamber.          This minimum capacity can be obtained by the provision of one tank or several tanks having a combined storage capacity which meets or exceeds the calculated volume.  Preferably the storage tank, or combination of storage tanks, is positioned between the heat exchangers so as to receive heated working fluid from the first heat exchanger and provide heated working fluid to the second heat exchanger.

Title: Faucet spring
Inventor: ROLAND R DOUGLAS
IPC: F16K3/08
Filed: 1988-08-09
Granted: 1991-12-24
Abstract: ABSTRACT OF THE DISCLOSURE      A faucet spring utilized to urge the faucet seal member into sealing contact with the rotatable valving member and prevent large debris,  such as valve washer screws from previous faucet assemblies,  from contacting the valving member under the fluid pressure.   The coil spring has a substantially frusto-conical  configuration with a smaller diameter upper end which engages the seal and urges  it  against the valving member.   The  larger diameter  lower  end  of  the  spring  engages  an  annular shoulder of the counterbored inlet passage of the valve assembly.  The lower end of the spring also includes an obstruction member  formed as  an extension of the coil spring which extends into the opening  of the  spring's lower end to prevent large debris from traveling through the spring and seal.   As a result,  the faucet spring provides  the  added  function  of  preventing  potentially damaging debris from contacting the valving member.

Title: Process for spinning starch fibers
Inventor: EDEN JAMES
IPC: D01F9/00
Filed: 1988-10-03
Granted: 1993-03-09
Abstract: ABSTRACT     Raw starch is slurried in an aqueous solution containing up to and above saturation levels of an ammonium sulfate, ammonium monobasic or dibasic phosphate, sodium sulfate or mixtures thereof.  The slurry is then cooked at temperatures above about 150°C.  The resulting starch cook is then extruded using conventional methods into a coagulating salt bath thereby producing a starch fiber.  When the starch is cooked in the presence of a salt prior to spinning in the coagulation bath, dilution of the salt in the coagulation bath is minimized, thus reducing the evaporation load and consequently lowering the initial capital cost of the evaporation as well as the operating costs over those required by the methods of the prior art.

Abstract: Apparatus and method for controlled growth of large single crystals in plate/slab form from a melt, characterized by a crucible having a narrow thickness dimension that is small enough to permit adequate control over the growth interface across the full width of the crucible and a scalable larger width dimension permitting the growth of crystals having a width many times the thickness of the grown crystal. The apparatus and method are further characterized by side heating members located in close proximity to the wider side walls and the hence the melt across the width of the crucible for  obtaining  and  maintaining  control  over  the  growth interface.   The apparatus and method are scalable for the growth of large single crystals such as 1 meter by 1 meter square crystals which heretofore were not obtainable by known apparatus and melt growth methods at least in the case of single crystals such as calcium fluoride.
