Title: Locking mechanisms and method of magnetizing a locking magnet therefor
Inventor: SEDLEY BRUCE SAMUEL
IPC: H01F7/02
Filed: 1982-06-18
Granted: 1985-10-17
Abstract: The method starts from a magnet (14) having its opposite ends magnetized such that north and south pole be equally strong. One pole (N) of the locking magnet is connected to the opposite pole (S) of a second magnet (30). A magnetic field is applied to the opposite end (S) of the locking magnet, and is collapsed to reverse the polarity of said opposite end, whereby the strenght of the magnetic pole adjacent the second magnet becomes relatively weak compared to the pole adjacent the magnetic field. Use in order to prevent undesirable interaction between the locking magnets in magnetic locksets.

Abstract: A rigid, non-removable hollow cylindrical insert is located in the end portion of a deformable plastic tube. The end portion of the tube is situated between thin film layers with the insert aligned with an edge to be sealed. The assembly is placed between the mating pressure dies to be welded. In a single operation, the edges of the layers are sealed to form a pouch as the tube end portion is welded to the layers along the seam at the top of the pouch. The insert supports the tube end portion in a non-deformed state during welding. This permits an effective weld to be obtained with tubes of various structures and, particularly, very soft tubes such as one with thin walls composed of polyvinylchloride.

Abstract: A highly portable pressure intensifier for use with a borehole dilatometer head having an expandable body defining an internal cavity to measure deformation properties of in-­situ rock masses. The housing (17) of the intensifier (10) comprises two axially aligned interconnecting cylinders (18,19), one of which is of substantially larger diameter. The larger cylinder (18) has a reciprocating piston (54) mounted therein, the piston (54) having a plunger portion (55) which extends axially into the smaller cylinder (19). The smaller cylinder (19) is connected to the cavity of the dilatometer head (11) by means of high pressure tubing (13). The larger cylinder (18) is filled ahead of the piston with a first working liquid. The second cylinder (19), the dilatometer head cavity and the interconnecting tubing are filled with a second working liquid. Increasing the pressure of the first working liquid displaces the plunger portion (55) into the smaller cylinder (19), substantially increasing the pressure of the second working liquid, which latter increase causes the dilatometer head (11) to expand so as to deform the rock of the borehole in which it is placed. A pressure transducer (70) and a linear variable differential transformer (89) are provided for deriving signals representing changes in pressure and volume respectively.
