Patent CA-2024568-A1 (CA)
Inventor: HASE ALFRED M
IPC: H01F27/06
Filed: 1990-09-04
Abstract: An enclosure or cabinet is provided for single phase rectifiers that has a very low profile, low noise, efficient cooling, low temperature rise, and which is competitive with switch-mode technology rectifiers. The rack includes a chassis which is very strong and that has a horizontal base and a rear vertical wall secured to each other, and all of the components are mounted to the base or rear wall, or to components already mounted, with the single exception of a supervisory control panel which is mounted on the door panel that has been hinged to the front edge of the base. Light-weight sheet metal side walls and cabinet cover may be formed as a hood and placed over the assembled components to close the enclosure. A UI transformer and an EI saturable reactor are each mounted to the rear wall of the chassis, one above the other, and are wound in such a way that adequate air spaces exist between the coils on the core legs. Generally the UI transformer is also supported from the base. Cooling slots are formed in the horizontal base and vertical rear wall, in the cabinet side walls, and may also be formed in the cabinet top cover. All electrical connections are made at the front of the cabinet, thereby assuring easier assembly, using less material and with less chance for mistakes to be made.

Abstract: A surface-type fastener is disclosed which includes a pair of base strips (11, 11') each having longitudinal ridges (13) and transverse ribs (14) defining therebetween elongate apertures (15). The fastener has a number of rows of interengaging elements (12), each having a stem portion (16) extending substantially at right angles from the longitudinal ridges (13), and an arm portion comprised of a pair of hook shaped engaging arms (17). The arm portion is which is substantially as large as the associated aperture (15). The interengaging elements (12) in one row are offset in position with respect to those (12) in the next adjoining row. In each row, the interengaging elements are spaced-apart longitudinally to provide an engaging space in which the arms (17) of the base strips (11, 11') can be resiliently engaged with one another when said base strips (11, 11') are pressed together. The advantage of the fastener of the invention is in that it is suitable for use not only in flexiblearticles such as clothing, sleeping bags etc. but also in relatively rigid articles such as decorative panels, furniture etc.

Patent CA-2028855-A1 (CA)
IPC: A01H4/00
Filed: 1990-02-23
Abstract: The present invention is a method for reproducing coniferous trees by somatic embryogenesis using plant tissue culture techniques. The method comprises a multistage culturing process. A suitable explant, typically the fertilized embryo excised from a mature or imma-ture seed, is first cultured on a medium that induces multiple early stage proembryos. Preferably the proembryos from the induction stage are further multiplied in a second culture having reduced growth hor-mones. The early stage proembryos are then placed in or on a late stage proembryo development culture having a significantly higher osmotic potential than the previous stage or stages. This increased osmotic potential medium is a critical key to the development of very robust late stage proembryos having at least about 100 cells and multiple suspensor cells. Culturing from this point continues in an embryo devel-opment medium very low in or lacking growth hormones but containing abscisic acid. After a period of several weeks cotyledonary embryos will have formed. These have a well defined bipolar structure with cotyledonary primordia at one end and a latent radicle at the other. Culturing to this point is carried out in darkness or greatly subdued light. The cotyledonary embryos are then transferred to a growth medium with a light/dark photoperiod for development of plantlets. The plant-lets may then be transplanted to soil for further growth. The method has been successful with a broad range of species and with numerous genotypes that could not previously be propagated by embryogenesis.
