Abstract: A device for measuring the contour of a surface along a scanning line. The device includes an electro-mechanical transducer with a scanner arm on whose free end there is a sensing tip. The other end of the arm is connected, via a pivot bearing whose axis of rotation is parallel to the surface to be scanned and vertical to the scanning line, with an advance mechanism. The advance mechanism moves the pivot bearing along the scanning line. The transducer emits, corresponding to excursions of the sensing tip transverse to the scanning line, a measurement signal that is fed into a recording device. The recording device records the electrical signal on the basis of distance or time. A control device is provided into which the electrical measurement signal is fed. On the basis of the magnitude of the electrical measurement signal, the control device produces an advance or a lag of the advance mechanism or of the time axis of the recording device relative to the advance of the advance mechanism.

On the inside of the legs of the rotor are mounted a plurality of permanent magnets forming the poles of the motor. Radially opposite magnets are of the same polarity. Control of the switching of the current through the windings is by means of Hall Effect devices sensing the change in polarity of a ring shaped magnet means having the same number of poles as does the permanent magnets.

Abstract: An improved satchel-style tackle box wherein access to the storage compartments can be had through the upper end or through the front wall of the box. Hence with the box of the present invention, there is no need to turn the box over in order to obtain access to all its storage compartments. The elimination of the need to turn the box over is accomplished by adding a pull out drawer to the lower part of the box. One or more storage compartments are then developed in the box above the drawer storage compartment. The projecting edge around the drawer opening in the box cooperate to prevent the rain water and other casual water from getting into the box, between the drawer and the opening, when the drawer is closed. Novel latches secure the drawer in its closed position and assist in preventing the ingress of water into the drawer. The latches are readily moved out of the way when the drawer is to be opened. A handle is mounted on the front wall of the box to facilitate carrying the box.

Abstract: A system for suspending a receiver in a hearing aid and acoustically linking the receiver with the region external to the hearing aid. A shaped mandrel is placed inside the shell of the hearing aid and a liquid material is poured into the shell. The liquid material polymerizes to form an elastomer that is around the mandrel and in contact with the shell. The mandrel is then removed from the shell, leaving a receiver cavity and sound channel. A receiver is inserted into the receiver cavity. The receiver cavity holds the receiver, and the sound channel grippingly engages an acoustic output port on the receiver. The sound channel extends between the receiver and shell, acoustically linking the receiver with the external region.
