Patent CA-1283676-C (CA)
Title: Crop sprayer shield
Inventor: SEMPLE D GAVIN
IPC: A01M7/00
Filed: 1987-05-14
Granted: 1991-04-30
Abstract: ABSTRACT OF THE DISCLOSURE     The conventional spray shield for use on crop sprayers includes a large cover for the entire spray boom.  The cover extends downwardly to the top of the crop being sprayed, and consequently impedes access to the spray nozzles and hides the spray pattern.  Thus, the operator of the sprayer is not aware blocked nozzles.  A solution to the problem is to provide individual spray hoods over each nozzle, the hoods having essentially the same shape as the spray produced by the nozzle, i.e. conical with an elliptical horizontal cross section at the discharge end.          The hoods are sufficiently short that they terminate above a crop in the use position, so that the sprays are visible and the nozzles are readily accessible.

Title: Multiple effect evaporator with an evaporative condenser as a liquid evaporation effect
Inventor: ELMORE CARL
IPC: B01D1/26
Filed: 1987-05-25
Granted: 1992-09-29
Abstract: ABSTRACT     A multiple effect evaporator system and a process for concentrating a process liquid wherein evaporated process liquid from one effect serves as heating fluid in an adjacent effect.  Low energy heating fluid in vapor form is fed to an evaporative surface condenser where it is condensed and collected as clean and foul condensate.  Coolant for the evaporative surface condenser is provided in the form of process liquid from one of the effects. Prior to passage into the evaporative surface condenser, the process liquid is cooled.  In the cooling circuit of the evaporative surface condenser, the process liquid absorbs the heat of condensation of the heating fluid and subsequently rejects that heat into a counter flowing air stream.  The process liquid is thereafter heated and returned to another of the multiple evaporator effects.

Title: Microwave heating
Inventor: KEEFER RICHARD M
IPC: A47J27/00
Filed: 1987-11-18
Granted: 1993-01-26
Abstract: Abstract of the Disclosure A susceptor for use in the heating of a foodstuff or other material in a microwave oven is constructed to have at least two regions that are each adapted to couple with and hence absorb microwave energy to generate heat in such regions, such heat then being transferred to the material. The invention is characterised by one such region having a different lossiness from the other, the regions being contiguous with each other.  They preferably have a stepwise discontinuity of lossiness between them, which causes higher order mode or modes of microwave energy to be generated or accentuated.  The susceptor may be a separate panel or may be a wall component, e.g. the bottom, of a container or utensil, or a removable cover therefor.

Abstract: ABSTRACT          A gas turbine engine blade has an abrasive material tip with a used superalloy matrix and evenly distributed ceramic particu-late. The matrix will have a desirable metallurgical structure characterized by fine dendrites and remnants of the original powder metal structure from which it was made.  Due to the fusion of the tip, the peripheral edge will tend to be curved. To lessen the effect of thermal strains on such an abrasive tip, a sheath of a superalloy, such as a portion of the the turbine blade substrate, extends along the side of the abrasive. The sheath may be present only in the thicker leading edge part of the blade airfoil.

Granted: 1991-02-05
Abstract: ABSTRACT OF THE DISCLOSURE          Method and measuring instrument for identifying the diffusion length of minority charge carriers for non-destructive detection of flaws and impurities in semiconductor crystal bodies.  The method provides that the semiconductor crystal body is positioned between two electrolyte-filled measuring chamber halves and that the minority charge carriers of the photocurrent that results at a front side of the semiconductor crystal body due to irradiation is detected by an applied constant voltage between a backside of the semiconductor crystal body and a rear electrolyte  at the backside of the semiconductor crystal body.  Taking the thickness(D)of the semiconductor crystal body into consideration, the diffusion length (L) can be calculated from a mathematical equation using the quotient of the minority charge carrier current IG/IO occurring at the backside and at the front side of the semiconductor crystal body.  The method provides topically resolved measurements for irradiation of the semiconductor crystal body.  A measuring instrument for the implementation of the method is disclosed.  The method can be used for determining the quality of semiconductor crystals.
