  • Patent number: 4777714
    Abstract: A quick-change mount for chucks is incorporated into a rotatable hollow spindle (10) of a machine tool and comprises servo-actuated drive sleeve (32) for power transmission to clamp the chuck (20) to the spindle flange (12). Slidable within the drive sleeve is a servodriven clamping sleeve (46) adapted for having fitted thereto the clamping jaw carrier (70) of the chuck. The clamping sleeve includes an annular series of holes (52) for guiding radially movable coupling element (50), which in order to get into coupling condition are displaced partially into a circumferential groove (72) of the clamping jaw carrier by means of a shifting sleeve (58), and in order to bring about the release condition are enabled to leave said groove for an annular recess (60) of the shifting sleeve (58). The shifting sleeve is spring biased into the condition to bring about the coupling position, from which it can be released by means of a catch member (64), when the fixation of the chuck is removed (FIG. 1).

  • Patent number: 4771798
    Abstract: A technique of attaching a hair replacement unit to the head of a recipient includes steps involved in braiding isolated tufts of the recipient's natural hair with a pair of lubricated translucent threads to form a securement braid around the head of the wearer. The threads are knotted and positioned about a first isolated tuft so that the threads are arranged on opposite sides of the first tuft and in juxtaposed relationship with one another so as to be directed generally tangentially of the scalp, and the first tuft is arranged between the two threads so that the free end of the first tuft is directed generally perpendicular to the scalp. The threads are then braided with the first tuft by repeatedly crossing the two threads and passing the free end of the tuft between the crossed threads and around the first thread to form a first braid section of the securement braid.

  • Patent number: 4768128
    Abstract: An improved, low cost, water activated pressurized gas release device utilized for inflating flotation equipment, such as life jackets, when dumped into the water. The device includes a one piece die cast housing (12) formed of an electrically conductive material. All major components of the device are mounted within the housing with the exception of the container (14) of pressurized gas, a manual actuating device (18), and a battery housing (16). A portion of the housing or container acts as a first contact when immersed in an electrically conductive fluid. A battery (64) is disposed within the battery housing (16) which is in turn received within a battery bore (34) in the housing (12). The battery housing is provided with an exposed sensor plate (76) the inside of which is in electrical contact with the battery anode (74). The plate acts a second contact.

  • Patent number: 4764145
    Abstract: A wildlife call including a hollow tube having an open sound-escape end and an opposite open mouthpiece includes a resonating membrane associated with the mouthpiece which is arranged in a planar condition and oriented at an acute angle to the longitudinal axis of the mouthpiece. For support of the membrane in such an arrangement, the mouthpiece includes a head portion which protrudes axially of the tube and opposite the sound-escape end and which defines a continuous edge that bounds a substantial portion of the opening of the mouthpiece when the mouthpiece is viewed axially and theretoward. The mouthpiece further includes an end wall covering a substantial portion of the mouthpiece opening not covered by the continuous edge, arranged generally within a radial plane of the tube, and defining a substantially free edge extending across the mouthpiece. The resonating membrane is thus arranged angularly to the plane of the end wall.

  • Patent number: 4761878
    Abstract: An electrical connector for supplying electrical power to a machine at particular voltage and phase magnitudes selected, the connector having one part adapted to be mechanically and electrically connected to the machine and another part adapted to be electrically connected to a conductor providing the electrical power to be supplied. The connector comprises a plurality of pins on one of the connector parts and a corresponding plurality of mating slots on the other of the connector parts adapted to receive the pins when the connector parts are connected together. One of the pins and the corresponding one of the mating slots serve to complete an electrical ground circuit and have a fixed orientation independent of the selected voltage and phase magnitude for the particular connector.

    Abstract: A sensor for an electrostatic voltmeter comprising an elongated vibratory element supported at one end in the manner of a cantilever beam, a sensitive electrode on the vibratory element near the other end and adapted to be disposed toward an electrical field or potential being measured, a driver chip on the vibratory element for vibrating the element in a direction to vary the capacitive coupling between the electrode and the electrical field or potential being measured, and an amplifier on the vibratory element in direct proximity to the sensitive electrode and having an input connected to the electrode and an output adapted for connection to the electrostatic voltmeter. The amplifier is mounted directly on the vibratory element so as to be in synchronous motion with the electrode. Preferably the electrode is mounted on one side of the vibratory element and the amplifier is mounted on the opposite side.

  • Patent number: 4757610
    Abstract: Surface mount networks and methods of making. One form of a network is a single in-line network. According to one method all components are mounted within a bar stock of generally rectangular cross section, the components have end caps disposed over a cylindrical body portion, which body portion is received within grooves on the bar stock material, and the end caps extending to the sides of the bar stock. A portion each of the end caps lies in a plane to one side of the bar stock so that the network can be mounted on the conductive traces of a printed circuit board. The single in-line network may also be molded to its final configuration. In another form two in-line networks are provided with a bus between adjacent end caps, a portion of the cylindrical wall surface of the end caps lying in a common plane on the periphery of the network and being adapted to be surface mounted onto the conductive traces of a printed circuit board.

  • Patent number: 4755139
    Abstract: An orthodontic anchor appliance for repositioning anterior teeth of a dental patient includes a relatively hard splint portion for securement to preselected ones of the patient's posterior teeth positioned on opposite sides of the dental arch containing the anterior teeth desired to be repositioned and an elastic positioner portion joined to the splint portion for urging the anterior teeth to a preselected position. Both the splint portion and positioner portion are formed from appropriate materials which are pliable when a pre-hardened or pre-cured condition and are applied to and shaped about a diagnostic model of the patient's arch containing portions simulating the anterior teeth when positioned in the preselected position. When the appliance is operatively positioned within the mouth, the splint portion is closely fitted about and thereby anchored to the posterior teeth and the elastic positioner portion is closely fitted, about, in a flexed or deformed condition, about the anterior teeth.
