Abstract: An electrical connector is provided with a plurality of contacts, each of the contacts having an insulation-opening terminal element of sheet metal construction to electrically contact an insulated conductor. The contact is advantageously constructed for receiving an insulated stranded conductor, but is equally applicable for receiving an insulated solid conductor. Each contact includes an active portion, of either male or female configuration, a terminal element portion, and an intermediate portion connecting the active and terminal element portions. The terminal element portion preferably includes an elongate open channel of U-shaped cross-sectional configuration having side and bottom walls, the sidewalls including opposite portions dimpled in to provide inner detents forming, and separated by, a conductor-receiving notch for opening the insulation of the conductor and electrically engaging the underlying exposed conductor. A plurality of different embodiments of a detent are offered, each of which advantageously includes an enlarged wiping surface, a notch entrance and a smooth portion adjacent the notch entrance to prevent snagging, and possibly severing, of the individual strands of a stranded conductor.

Abstract: This invention relates to a method and apparatus for causing the display on a display device such as a cathode ray tube (CRT) to travel or advance in fractional stroke increments. The circuit includes a first counter, each unit increment of which corresponds to a predetermined fractional stroke increment of the display, and a second counter, each unit increment of which corresponds to a full stroke increment of the display, the second counter being connected to be incremented in response to an overflow from the first counter. The circuit also includes elements for determining and indicating the number of predetermined fractional stroke increments which the display is to be incremented and for incrementing the first counter by the indicated number. The counts in the first and second counters are utilized for controlling both the stroke and bit of the stroke of the display at which display of the first of successive characters applied for display begins.

Abstract: Apparatus and method are disclosed for measuring the speed of sound in water and other liquids with an accuracy in the order of + OR - 1/50,000 by using a single transducer and a reflecting target in an arrangement that detects the zero-crossover at the end of the first full cycle of the second reflected signal, and actuates the transducer at that time for retransmission of the acoustic signal. A standing wave produced by this method allows the input dynamic range to be in excess of 12 db. Operation of the apparatus is monitored through the power supply cable by momentarily shunting one of two resistors connected in series therewith in response to each retransmission. This monitoring technique allows the monitoring instruments to remain on the surface of the liquid with the power supply and one of the two resistors. A tunnel-diode threshold detector improves stability of operation over a wide range of temperatures.

Abstract: A switch-over contact for relays or switches in which the contact forces can be easily, yet accurately adjusted without costly adjustment operations. According to the invention, the two contact arms of the switch-over contact have the form of an arc, i.e., they are elastically bent in the undeformed or unstressed state, but assume essentially the form of a straight line segment in the deformed or stressed state. The switch-over assembly comprises a pair of fixed contact members, and a pair of resilient contact arms, the fixed ends of the arms being mounted at substantially a common point in the device, the arms being bent to substantially a straight line positioning the free ends of the arms between the fixed contacts. An armature actuates to move the free ends of the arms into and out of contact with the fixed contact members.

Abstract: Electrical connector including low-pass filter contact units formed by inductance means of ferromagnetic material and capacitance sleeve means of dielectric material on a central conductive portion; the capacitive sleeve means is preferably approximately the same diameter as the end portions of the contact unit to provide a relatively thin unit while obtaining highly effective filtering. The units are readily assembled and each unit is independently removable from and re-installable in a contact passage of a support body. Curved tines extend inwardly from openings in a common ground plate to wipingly engage arcuately spaced portions of an outer conductive sleeve during installation and removal, insuring excellent electrical contact. Preferably, the contact plate is of a thin resilient metal and is engaged by one or two backing plates.

Abstract: A method of squaring one or more elements, such as the print wires of a wire matrix print head, with a surface of a member in which the elements are mounted. The elements are of a material having a predetermined hardness which is less than the hardness of the material of the surface in which they are mounted. The first step of the method is to adjust the position of all of the elements relative to the surface so that they extend slightly from the surface. The extending portions of the elements are then ground with an element having an abrasive surface, the material of the abrasive surface having a hardness which is greater than the predetermined hardness but less than the hardness of the material for the surface in which the elements are mounted. The grinding step is terminated when the material of the abrasive surface starts being worn away by the harder material of the surface in which the elements are mounted.
