Patent CA-2104195-A1 (CA)
Inventor: SCHWEITZER EDMUND O III
IPC: H02H3/40
Filed: 1993-08-16
Abstract: The relay includes means for obtaining current and voltage samples on the power transmission line for a particular possible fault type. The current sample is multiplied by the replica impedance of the power transmission line, while the voltage sample is multiplied by a polarizing voltage to provide a first complex expression having a real portion and an imaginary portion. The product of the current sample and the replica impedance is multiplied by the polarizing voltage to produce a second complex expression having a real portion and an imaginary portion. The real portion of the first complex expression is then divided by the real portion of the second complex expression to produce a scale value m which is compared against known reference scale values for each zone, so as to determine underimpedance conditions in any one of the zones.

Title: Closure system for covered receptacles and the like
Inventor: SHAMIS NEAL B
IPC: B65D43/02
Filed: 1992-04-23
Abstract: ABSTRACT OF THE DISCLOSURE    A child's drinking cup has a lid combining positively interengaging latches with a biasing feature which forces the lid upward with respect to the container in order to more firmly effect latching.  A series of projections formed along the interior upper periphery of the container register with latching slots formed along the outer surface of a skirt which depends from the lid, which is dimensioned to fit closely within the opening of the container.  An annular flange extends from the outermost periphery of the lid to overlap a portion of the skirt.  The outer upper periphery of the container is tapered outwardly to force the flange to flex when the lid is placed on the container thus imparting an upward force to the lid and, thereby, to the lug-and-latch combinations when the lid is turned to register the lugs with the latches.

Title: Coupling ring and method of making same
Inventor: KEATING HENRY M
IPC: F16L21/02
Filed: 1992-09-23
Abstract: A coupling ring (10) for circular ducts (30, 31) is formed of a single piece of sheet metal and has oppositely extending flanges (46, 47) connected together by an annular channel-shaped rib (12) which cooperatively with the flanges (46, 47) defines oppositely opening grooves (20, 22) containing sealant (68, 70). The relative dimensions of the grooves (20, 22) is such that a hydraulic lock is avoided at the time the coupling ring (10) is telescoped onto the ducts (30, 31). Proper sealing can be visually determined by inspection. In a modified embodiment one of the grooves (22') has a larger diameter than the other (20') so that the larger diameter groove (22') may be telescoped over the male end (124) of conventional fittings used in circular sheet metal duct work, while the smaller diameter groove (20') may be connected to the duct (D) itself. Thus, a coupling is provided for connecting ducts (D) to each other as well as to the male ends (124) of duct fittings.

Abstract: ABSTRACT A method of upsetting and flaring a thin-walled metal tubular probe with one closed end onto a non-metallic plate in a single tooling set-up. The closed end of the tubing probe is inserted in a hole in the plate and a mandrel inserted in the open end of the tube and spring biased to register against the interior of the closed end of the tube which has an anvil washer received thereover which supports the tube wall. A pilot tool is registered against the closed end of thetube; and, an annular tool is received over the mandrel and registers against the open end of the tube. With the annular tool supporting axially the open end of the tube, the pilot tool is moved against the closed end of the tube and bulges a portion of the tube in a recess provided in the plate or in the anvil washer against one side of the plate. The annular tool is then moved axially to flare the open end of the tube against the opposite side of the plate.

Title: Shaft clutch mechanism and its production
Inventor: MILLER JAMES R
IPC: F16B7/14
Filed: 1993-03-12
Abstract: A shaft clutch mechanism, and method and apparatus for its production are disclosed. The shaft clutch mechanism has an upper body folded into a polygonal cross section with a plurality of fingers, each finger attached to and extending from a flat section of the upper body. The shaft clutch mechanism is pressed on to one end of an inner nested element of a telescoping body and is placed inside an outer element where the fingers are slightly deformed, providing slight friction sufficient to hold the inner element in place, but still allowing it to slide relative to the outer element. The method and apparatus for producing the shaft clutch mechanism use a two stage press and a bending device to take a continuous strip of material to form blanks which then are bent to form the shaft clutch mechanism that is pressed on to the inner element of the telescoping body.

Title: The determination of the carbon equivalent in structure modified cast iron
Inventor: BACKERUD STIG L
IPC: G01N33/20
Filed: 1993-04-06
Abstract: The invention relates to a method for determining the carbon equivalent (C.E.) of structure modified cast iron melts, and to the use of this method for adjusting the composition of a structure modified cast iron melt. The method is based on the introduction of one or more pieces of iron of low carbon content into a sample container. The iron piece or pieces has/have a size such that the iron piece/pieces will not melt completely when the sample container is filled with melt, which is allowed to solidify. The temperature of the melt is recorded as the melt solidifies. When practicing the method, there is obtained a well-defined absolute temperature as the temperature passes the .gamma.-phase liquidus line, or a temperature difference in relation to the eutectic temperature of structure modified cast iron of a closely similar type. The carbon equivalent is determined on the basis of a phase diagram applicable to this structure modified cast iron. The carbon equivalent of the melt is adjusted by adding carbon and/or silicon or iron of low carbon content.

Filed: 1994-12-08
Abstract: In a tracking or focusing servo control loop (3b, 3c, 41, 20; 3a, 42,  21), there are provided a switch element (6a; 6c) for switch-controlling a tracking or focusing error signal,  and a smoothing circuit  (7a;  7c)  for switching passage the error signal.

IPC: H01P1/20
Filed: 1994-12-21
Abstract: The present invention relates to a radio frequency filter the resonators (6,7) of which are made up of a wire wound into a cylindrical coil comprising a number of turns and of a surrounding casing (41). Finger-like projections (3) of an insulating plate (1) support the conical coils from the inside, and the coupling to the resonator is from a microstrip line (8), at a tap point (21), on the insulating plate. Each cylindrical coil has, adjoining the first turn, a straight portion (2) which is parallel to the axis of the cylindrical coil and extends towards the bottom plate (44) of the filter. On the inside surface of the bottom plate (44) there is a lead (51) one end (E) of which is short-circuited and the other end open, and the tip (12) of the straight portion (2) adjoining the cylindrical coil (6) is in contact with this lead (51). In this case, in spite of any rotation of thecylindrical coil relative to its own axis at the assembling stage of the filter, the distance of the tap point from the short-circuited end (E) of the lead (51) willremain unchanged, in which case the tap impedance will not change. The lead (51) is preferably a microstrip line on the surface of the insulating plate.
