Abstract: The invention relates to a connector plug for a medical instrument, in particular a bipolar electrode or forceps, comprising an insulating body for connecting two limbs of the instrument, wherein the insulating body has openings for receiving, inserting or sliding in the limbs, wherein in each of the openings a latching or spring element is provided for fastening one of the limbs of the instrument in the insulating body.

Abstract: The invention relates to a guide assembly for an instrument comprising two legs, in particular forceps, the guide assembly comprising first and second guide elements, wherein the guide elements each comprise a base body, provision being made in each case on the outer side of the base body for an arrangement for snapping into place in an opening on an inner side of the legs of the instrument, provision being made on the inner side of the base body in the case of the first guide element for a protrusion and in the case of the second guide element for a recess, which is complementary to the protrusion, and provision being made in each case for a hollow on the outer side of the base body of the first as well as the second guide elements.

Abstract: Measuring the hearing ability or the diagnosis of the hearing loss of a person can be achieved by the recognition of a plurality of sound samples by said person. The initiation of the sound samples to be recognized is performed by said person itself. In other words the various sound samples at different frequencies or for different sound types and different sound pressure levels are initiated by the person whose hearing ability or hearing loss is to be determined. The sound samples are generated in situ, which means within a hearing aid worn by the person.

Abstract: A signal connector assembly with a plug contact within a plug having a high resistive portion. When the plug of the assembly first makes contact with the electrical receptacles within a mating receptacle, the high resistive portion prevents a current surge. As the plug is further inserted into the receptacle, the energy passing from the plug to the receptacle is gradually increased. Eventually, the receptacle contacts within the receptacle pass the high resistive portion and make contact with the conductive portion of the plug contact, thereby permitting transmission of valid signals without the generation of spurious errors.

Abstract: For optical applications, transparent amorphous thermo-plastics, such as polyaryl ether ketones, are of considerable interest. However, polyaryl ether ketones have inadequate UV stability and weathering resistance while amorphous polyaryl esters do not have these negative properties. The properties can be improved by means of polymer alloys, giving weathering-resistant materials from homogeneously mixed polymers which comprise at least one amorphous polyaryl ether ketone and at least one amorphous polyaryl ester.

Abstract: Homogeneous polymer alloys based on sulfonated, aromatic polyether ketonesHomogeneous polymer alloys comprising sulfonated, aromatic polyether ketones and at least one polyamide as the main constituents, wherein the polyamide is a completely aromatic polyamide.

Abstract: Polymer alloys based on polybenzimidazoles are of great interest in industry due to their extraordinary thermal and mechanical properties. Alloys composed of a homo- or copolybenzimidazole and poly-N-vinylpyrrolidone are homogeneously mixed and have only one glass transition temperature.

Abstract: An improved spindle control mechanism for a lathe that includes, in preferred form, a rotatable control knob operably related to a plurality of spindle motor control and servo-control switches by a switch drum fixed thereto and operably connected to a spindle transmission through a control shaft by a connector link pivoted in an eccentric position at one end to the control knob and pivoted at the other end to a lever arm fixed to the control shaft. Rotation of the control knob into a forward position simultaneously translates the lathe's transmission into a forward spindle rotation position and starts the spindle drive motor. Rotation of the control knob into an intermediate stop position simultaneously stops the spindle drive motor and activates the spindle servo-control switch (which permits the spindle's rotation speed to be changed by a separate spindle servo-control mechanism, if desired).

Abstract: A dial assembly adapted to be secured to a lead screw and operative to enable measurements of a machine element effected by the lead screw to be measured in either English or Metric units of measure. The dial assembly includes two different dials interconnected by a gear train, which gear train comprises a spur gear fixed to each dial and a continuous, toothed ring or belt drivingly interconnecting the spur gears.
