Patent CA-2004106-A1 (CA)
Inventor: SYNOFZIK REINHARD
IPC: F42B5/067
Filed: 1989-11-29
Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for compressing a propelling charge for a subcaliber discarding propelling cage sabot projec-tile is provided.  The charge surrounds a tail region of the projectile, and is inserted into a propelling charge casing.  The method includes the steps of inserting the sabot projectile, in a downward oriented direction, into a vertically oriented cylindri-cal open ended chamber having a diameter corresponding substan-tially to the inner diameter of the cylindrical propelling charge casing.  A piston is provided at the lower end of the chamber and is axially moveable in the chamber.  The chamber is filled with propelling charge powder, which is radially compressed.  Then, the sabot projectile and the compressed propelling charge is moved axially upward by means of the piston to insert the propelling charge and at least the portion of the projectile surrounded by the propelling charge into a cylindrical charge casing.  The caliber of the sabot of the projectile is less than the inner diameter of the propelling charge casing, and a front end surface of the piston is provided with a recess for receiving a front por-tion of the projectile and the caliber sized portion of the sabot and having an inner contoured portion which is adjacent the front end surface of the piston and which provides a transition from the caliber of the sabot to the diameter of the chamber.  Prior to the step of filling the chamber, a transition member whose outer contour corresponds to the inner contoured portion of the recess is inserted into the recess to form a shouldered cover for the propelling charge casing, whereby the transition member is suppor-ted by the piston.  During the step of axial movement, the sabot projectile, compressed propelling charge and transition member are moved until the upper free end of the transition member lies against the open end of the cylindrical propelling charge casing.          The free end of the transition member is connected to the free end of the propelling charge casing to cover the open end of the propelling charge casing.

Title: Method and apparatus for formation and delivery of insect attractant based on carbon dioxide
Inventor: DIEGUEZ JOSE M
IPC: A01M1/02
Filed: 1990-10-04
Abstract: A method and apparatus to prepare and deliver a gas mixture of constant composition of liquid chemical compounds soluble in liquid carbon dioxide to be used as an enhanced attractant for biting insects. The mixtures can be prepared in high pressure vessels where carbon dioxide remains liquefied under its own vapor pressure or in low pressure vessels where carbon dioxide is kept liquid, at low pressure, by cooling it with a refrigeration unit. Direct vaporization of the liquid mixture from these vessels results in a gas mixture of constant composition. This mixture is to be delivered in a continuous or pulsed flow to an insect trap. These baited insect traps are an ecological alternative to chemical insecticide methods of insect control currently in use.

Abstract: The invention relates to a longitudinal laminate board (1) of mineral wool to be used as a core of a sandwich element having surface layers preferably of thin sheet metal on each side. The laminate board consists of adjacently disposed rods (2) whose fibre plane form an essentially right angle to the plane of the laminate board. The rods are jointed within the laminate board, but the joints (3) are prepared so as to eliminate their weaken-ing influence on the board. This has been achieved by matching the shape of the jointed end surfaces and connecting them. The end surfaces may be glued, compressed, form a finger joint, etc. in order to increase the strength of the joint. The invention also relates to a method for manufacturing the sandwich element. Having been cut from a mineral wool board, the rods are rotated (IIIa) 90°  and assembled (Va) with end surfaces facing each other into rods, are cut to a length equalling the one of the laminate board and are assembled into a laminate board onto which the surface layers are applied during lateral compression.

Filed: 1990-12-20
Abstract: COLOR ELECTOPHOTOGRAPHY FOR HIGH QUALITY HALF-TONE IMAGES                    ABSTRACT OF DISCLOSURE           There is disclosed here a class of liquid toner dispersions for developing electrophotographic images which give very high contrast half-tone dots with low contrast scanning light beams such as gaussian laser beams.  The advantage of these toners is enhanced by the use of high electric field electrophoretic development conditions with high replenishment rate under which conditions rapid development to high image densities is obtained.  This class of toners has toner particles of high mobility, low particle concentration in the dispersion, and a low fraction of its conductivity in the liquid milieu.

Filed: 1990-12-20
Abstract: A method and means is described wherein servo sectors written on a disk (or servo sections written on a tape) are equally spaced on a given track and read during seek, settle and  track  following  operations.   An  algorithm  is  used  to determine the allowable time separation between servo sectors (or  sections)  on  a  track  and  lengths  of  associated  data sections,  such as data sectors or variable length records, that may be accommodated on the disk or tape in such manner that each of the servo sectors (or sections) equally spaced on a given track is located within a data field of a data sector or within an identification region or immediately after an address indicating mark (such as address mark or index mark). The rate at which the servo sector (or section) is sampled is constant and independent of the number and lengths of the data sections.  As a result of this independent relationship, this technique is suitable for CLD recording, to banded disks using sectored  servo  as  in  conventional  FBA, and  also  even  to non-sectored  architectures,  such  as  count-key-data  (CKD), wherein the data is written in records of variable length, and to tape drives formatted in FBA or CKD.

Abstract: A steering mechanism for improving the turning radius of a tractor is disclosed wherein the wheels are turned relative to the steering axle simultaneously with a pivotal movement of the steering axle relative to the chassis of the tractor. A connecting link interconnects the pivot mechanism pivotally supporting the steering axle relative to the chassis with the steering mechanism such that a manipulation of the steering mechanism to affect a turning of the wheels affects a pivotal movement of the steering axle in the same direction the wheels are being turned. The pivot mechanism allows for pivotal movement of the steering axle about longitudinally extending horizontal axis in addition to the pivotal movement of the steering axle about a generally vertical axis relative to the chassis. A lost motion linkage interconnecting the pivot mechanism and the steering axle accommodates differences in arcuate movements due to the pivot mechanism and the steering axle pivotally moving about longitudinally spaced pivot centers.

Abstract: Color bleed (the invasion of one color into another on the surface of the print medium) using ink-jet inks is al-leviated by employing zwitterionic surfactants (ph-sensi-tive or pH-insensitive) or ionic or non-ionic amphiphiles.      The inks of the invention comprise a vehicle and a cationic dye. The vehicle typically comprises a low viscosity, high boiling point solvent, one or two amphiphiles at concentra-tions above their critical micelle concentration (cmc), while the dye typically comprises any of the dyes commonly employed in ink-jet printing. The amount of surfactant/-amphiphile is described in terms of its critical micelle concentration (cmc), which is a unique value for each am-phiphile. Above the cmc, micelles form, which attract the dye molecule and thus control the color bleed. Below the cmc, there is no micelle formation, and thus no control of the color bleed.
