Abstract: A template for use in cutting a good contained in a pan enables the baked good to be cut into a plurality of substantially equi-sized pieces. The template includes a substantially planar body including a plurality of first slots and a plurality of second slots. The plurality of first slots are substantially parallel and are spaced approximately equi-distantly across the body. The plurality of second slots are substantially parallel and are oriented obliquely with respect to the plurality of first slots.
Abstract: An upper end (10) for the inner tube of a core drill has a marking device comprising a pendulum (350) or hard ball (30) which runs in a circumferential track (24). The marking device adapted to be carried within a tubular upper end casing (12) which surrounds a spindle (11) which supports the inner tube of the drill. An indent washer (25) is positionable below the marking device and is oriented relative to the casing. When the upper end (10) is lifted, the marking device is driven into contact with the washer (25) and makes an impression. The orientation of the impression reveals the orientation of the drill. The impressioned washer (25) can be used to assist in noting or marking the core orientation after the drill is removed from the earth.
Abstract: An apparatus, of a compact pocket-sized design, for the description of accurate ellipses of an infinite number of conjugate and transverse diameters on flat and/or irregular surfaces, such as spherical or horizontal and vertical cylindrical tanks, having two identical, independent focal-point holders, a non-elastic inter-connecting cord and a variety of inter-changeable mounting bases to allow the mounting of the focal-point holders on soft, porous, non-porous, textured and metallic surfaces.
Abstract: A core orientation device for determining the in situ orientation of core samples taken during a drilling process. A sampling tube having a plurality of equispaced slots formed longitudinally on its sidewall permits the scribing of a longitudinal line on a core sample within the sampling tube. The slots for indicating the position of the core within the sampling tube, a test tube with etch mark to indicate the top point or position of the etch mark within the test tube and a connector for relating the said top point on the test tube to the longitudinal slots on the sampling tube sidewall permit determination of the in situ position of the core sample.
Abstract: An arm extends out over the surface on which the ellipse is to be drawn, from a support in the form of a base plate with a handle that can be grasped to hold the support in a desired position. A piece of string is slackly fixed at two space sites along its length to two selected places spaced along the length of the arm of the support. A string-follower is provided in the form of a shaft having an arm radially and rotatably projecting from its lower end. At a site displaced from the shaft, a perforation is provided down through this arm. A drawing instrument is mounted to the string-follower so that its drawing tip underlies the lower opening of the perforation. The string extends down through the perforation to limit to limit the envelope of excursion of the string-follower in drawing an ellipse.
Abstract: A magnetometer assembly wherein a magnetometer detector suspended from a gimbal is immersed in a wax so as to immobilize the detector. Desired gimbal operation is achieved by heating the wax in the vicinity of the detector.
