Patent CA-2104615-C (CA)
Inventor: CREWS GEORGE M
IPC: C08G12/32
Filed: 1993-08-23
Granted: 2002-09-17
Abstract: Ammeline-melamine-formaldehyde resins (AMFR) containing from 5-10% ammeline were synthesized by the polymerization of the sodium salt of ammeline, which must be made in advance, melamine and formaldehyde in basic medium (pH = 9.2 - 10.0). In this copolymerization, it is possible to make uniform random AMFR resins with any mole ratio of ammeline salt to melamine.      Preferably the AMFR resin will contain from 5 - 10% ammeline.      As an "ionomer" or a "polyelectrolyte", both the solid and solution properties of these resins (such as melting temperature, solubility, solution stability, etc.) depended directly on the mole ratio of ammeline to melamine and formaldehyde and/or on the pH value of the medium in which the AMFR resin was present. The pH value controlled the ammeline rings/ammeline's salt groups and also the ratio of unprotonated to protonated amino groups on both the melamine and ammeline rings. These polymers have different solubilities, cloud points and solution lifetimes (which depend on pH) than melamine-formaldehyde resins. AMFR systems containing from 5 - 10% ammeline are more flexible than MFR resins and exhibit different adhesion properties than MFR resins.

Abstract: An antenna has one feed for an S-band electromagnetic signal,  and a second feed constructed as an array of radiators  to  service  two  C-band  signal  channels.    A subreflector having a microwave frequency selective surface (FSS) is placed in front of a main reflector.  The C-band feed is constructed of an array of square aperture horns joined  by  separate  transmit  and receive  barline beam-forming networks,  and a meanderline polarizer to produce circularly polarized radiation patterns.  Tapered ridges extend longitudinally along inner wall surfaces of each of the horns to provide increased bandwidth to the C-band  feed.     The  frequency  selective  surface  is constructed, typically, of a generally planar substrate of material transparent to electromagnetic radiation,  and numerous metallic, generally annular, radiating elements, or resonators, arranged on the substrate in an array of repeating nested sets of the radiating elements.  The lower frequency S-band feed is located behind and to the side of the subreflector for transmission of radiation via a folded optical path to the main reflector.  The C-band feed is located in front of and to the side of the subreflector for transmission of radiation along a straight path through the FSS to the main reflector.  The locating of the two feeds to the slde of the subreflector permits the subreflector to be stowed by folding down upon the C-band feed, and the main reflector to be stowed by folding down upon both the S-band feed and the stowed subreflector.

Abstract: An improved wood-splitting maul (10, 30) wherein the striking edge is at an improved angle (2, 45). The improved angle (25, 45) makes the maul easier to use, more efficient, and provides less shock to a user's body. The improved angle (25, 45) is defined by a straight line (26, 46) essentially running along the length of the splitting edge (20, 40) (or hammer face) to a point at a pivot point (27, 47) defined between about the bottom end of the handle (14, 34) where the maul is grasped while in use and the approximate location of the elbow of the user of the maul and a line along the longitudinal axis (28, 48) of the handle (14, 34). The exact degree or the absolute optimum value of the angle is a function of the handle length, the distance of the splitting egde (20, 40) (or hammer face) from the handle axis and the size of the user of the maul. The efficiency is improved to such a degree that a handle (14, 34) of only 28 inches in length provides improved performance in the manual splitting of wood.
