Abstract:
A sizing gauge (4) is structured to be used with a patient (8) and is structured to enable an identification of a particular patient interface that is most appropriately sized for the patient. The sizing gauge includes a support portion (12) and a sizing portion (16). The sizing portion includes a first gauge element (36) and a plurality of second gauge elements (40A,40B,40C). The first gauge element is disposed on the support portion and is structured to be positioned at a first location on the patient's face. The plurality of second gauge elements are disposed on the support portion and are situated at locations spaced from the first gauge element. The distance between the first gauge element and each second gauge element is representative of a size in one direction (44) of each of at least some of the plurality of patient interfaces. At least one of the plurality of second gauge elements comprises a tactile feature.
Abstract:
A railroad wheel reference groove locating gauge for determining a measurement of an annular reference groove machined in a face of a railroad wheel spaced radially outwardly from an axle on which the wheel is mounted a predetermined distance indicative of the wheel diameter, with the measurement being taken while the wheel remains connected to the axle, the gauge comprising an elongate member (18) having a first end and a second end, indicia (16) on the elongate member at the first end thereof indicative of a length along the elongate member; and an attachment element (22) at the second end of the elongate member for detachably securing the gauge relative to an axis of rotation of the axle, with the elongate member extending radially to the first end thereof adjacent the reference groove on the wheel for enabling the use of the indicia (16) to determine the diameter of the reference groove.
Abstract:
An embodiment of the invention is directed to an electronic caliper which combines positioning and measurement in one unit without the use of hydraulics for subsea use. In certain embodiments, several attachments can be affixed to accommodate a range of measurement tasks. In a preferred embodiment, one jaw is adjustable and the other, or opposing, jaw is fixed, e.g. by bolting it on to a mounting structure. The jaws typically allow for the removal and replacement of other attachments. In another embodiment, the unit communicates to computer software for position control, precise indication and clamping for adjustment. In a preferred embodiment, computer software displays all feedback via laptop computer on surface. The caliper is maneuvered to a position proximate an object and used to measure a predetermined physical characteristic of the object. The measurement can be displayed, e.g. at the surface, using a computer with control software.
Abstract:
A wrench selector (10) provides for the quick and accurate checking of the dimension of a nut or bolt across the flats thereof, in order to determine the corresponding size of the wrench or socket required for use therewith. The selector (10) incorporates two jaws (18, 22), with the first jaw (18) extending from an elongated scale (12) and the opposite jaw (22) extending from a body sleeve (16) through which the scale (12) slides. The scale (12) includes several rows of dimensional numbers (44) thereon, with each of the numbers corresponding to a distance between the two jaws (18, 22). The numbers are staggered diagonally across the face of the scale (12), in order to spread them for greater legibility. The body or sleeve (16) includes a set of windows (48a-48e) spaced laterally thereacross, which in combination with the diagonal array of dimensional numbers (44), results in only a single one of the dimensional numbers (44) being exactly aligned within a corresponding one of the windows (48a-48e) for any measurement. The scale numbers (44) correspond with the standard sizes of nuts and bolts used in industry, and the selector (10) may include inch and fractional inch measurements on one side and metric measurements on the opposite side. The selector (10) may be formed of various durable or disposable materials as desired and may be sufficiently small so as to fit within a conventional shirt pocket, in order to be readily available to the user at all times.
Abstract:
A gauge which gauges or measures chain elongation by means of a pivoting niche, a tension tine, and a number of variations which facilitate gauging and measuring.
Abstract:
There is disclosed a calliper, useful for measuring how much fat can be pinched beneath the skin, having jaws (4, 6) pivotally mounted for relative pivotal movement. The movement is amplified by a gear train (24, 26, 28 and 30). The final gear wheel (30) drives a toothed wheel the movement of which is sensed by an opto sensor (34). A digital readout indicates the spacing between the jaws for indicating the spacing between measuring surfaces of the jaws. In contrast to conventional callipers, which are used only to transfer a dimension from an object to be measured to a measuring device, the callipers disclosed give a direct reading of the spacing between the measuring surfaces.
Abstract:
A measuring instrument that includes a main body and a slide arm. The main body has a first plate with a first set of measuring identifiers, a second plate with a second set of measuring identifiers, a channel between the first plate and the second plate, and a measuring arm. The slide arm has a measuring arm and a slide rail. The slide rail is positioned within the channel and movable relative to the main body. The slide rail also has a plurality of measuring markers that can align with at least one of the measuring identifiers.

Abstract:
A set gauge (10) for measuring set (22) of a saw tooth (12) simultaneously on two sides of a saw blade (18). In the illustrated embodiment, a gauge has two body halves (32a, 32b) coupled to compression springs (38a, 38b) and elongated handles (50a, 50b) which, when squeezed together, separate the body halves of the gauge (10), a sufficient amount to fit over a saw blade (18). When the handles are released, clamping anvil faces (36a, 36b) disposed on the body halves clamp onto the saw blade behind a tooth to be measured. Gauge anvils (34a, 34b) measure the displacement or set of both sides of each tooth. The measured set is then displayed on two dial indicators (54a, 54b).
