  • Patent number: 9743998
    Abstract: The invention relates to a dental preparation instrument that includes a tool that rotates in an alternately reversible manner. The preparation instrument has a drive for the tool. The drive provides a continuous fully rotational motion, and a gearing is arranged before the tool. Said gearing converts the continuous fully rotational motion of the drive into an alternately reversing rotational motion, which is continuous as viewed over several reversals.

  • Publication number: 20140354389
    Abstract: A new family of programmable low-noise RF impedance transformers has been developed. These new transformers can be configured and operated to compensate for variable antenna output impedance. This enables better optimization of RF receiving-system SNR. For some applications, these new devices can be more compact and less expensive than any previously available. In particular, such new transformers can improve MRI system performance. This requires additional new art because MRI systems demand components which are not ferromagnetic, which do not produce spurious MR signals and which add very little noise to received RF signals. In various embodiments, these new transformers are comprised of remotely-controlled variable capacitors and inductors which are connected in networks between antenna element outputs and their following LNA inputs. These new step-programmable inductors and capacitors can be either electrically or pneumatically actuated.

  • Patent number: 4559839
    Abstract: A drive means for an oscillating spout is presented which includes a control mechanism which directs a control arm to perform the movement required by the spout and a transmission device which acts to transmit the control arm movement and reproduce it as spout movement. The control mechanism consists of a driving rod pivotally connected to an intermediate lever arm and a universal joint connecting the lever arm to the control arm. A novel movable torque means is associated with the universal joint and enables the spout to be moved in and out of a vertical orientation by overcoming the tendency of the components of the control mechanism to become axially locked in a 180.degree. angle. The movable torque means accomplishes this result by reducing the angle between the intermediate lever and control arm when that angle reaches 180.degree..

  • Patent number: 4548090
    Abstract: A supersonic vibration driven motor comprising a supersonic oscillator and a mass rotationally driven thereby. The oscillator is provided with a vibration disc secured thereto on an end face thereof opposite to the mass to be driven. The mass is integrally formed with a plurality of plate-shaped resilient vibratory pieces annularly arranged on the end face opposite to the oscillator and axially extending at a predetermined angle of inclination relative to the axis of the mass, the vibration disc and vibratory pieces being located so as to come in contact with each other at their end portions, whereby vibratory displacement of the supersonic oscillator is transformed into rotational movement of the mass by way of flexible deformation of the vibratory pieces. Alternatively, the resilient vibratory pieces may be formed integrally with the vibration disc.

  • Patent number: 4419905
    Abstract: A collar on the drive shaft of a bicycle pedal hub is mounted with means to displace the collar longitudinally along the shaft. The displacement is accomplished by a limited reverse rotation of the pedals and shaft. The direction of the displacement may be in either longitudinal direction and depends upon the position of the collar before the reverse rotation of the pedals and shaft. Displacement of the collar causes a bicycle transmission to shift gears.

  • Patent number: 4265128
    Abstract: A frequency selector (tuner) employs a turret to select the position of a slide member that is coupled to a variable reactance. The slide member is moved away from the turret by depressing an operating member and returns to the turret when the operating member is released. Depressing the operating member rotates the turret concurrently with the movement of the slide member, but interference between the slide member and cooperating position setting elements that project from the turret is avoided by a displacement mechanism on the slide member. The projection of the position setting elements is adjusted by turning the operating member. A further operating member is provided for turning the turret in opposite directions, the final position of the slide member being set by depressing the first-mentioned operating member.

  • Patent number: 4236418
    Abstract: A multi-element writing instrument is disclosed for use in computer-operated plotters or similar graphics systems. Successive applications of a linear force applied along the axis of the instrument are converted to rotary motion which is employed to select successive elongate writing elements normally positioned at a uniform radial spacing from the axis of the writing instrument. Each selected element is displaced in a substantially axial direction a distance sufficient to extend the writing point of the element through the exit opening of the instrument.

  • Patent number: 4235157
    Abstract: The ram housings of a volumetric metering stuffer are provided with ram seals to prevent leakage of the product being stuffed. The rams are reciprocated translatorily along substantially straight lines to prevent sidewise thrust on the seals. Cushions absorb the shock incident to the ends of the strokes of the rams and provide smooth deceleration thereof. Each ram has a clean-up cage to receive the ram when the ram is withdrawn from its housing.

  • Patent number: 4221236
    Abstract: A steppable mechanism is described comprising a cam member formed with a series of interconnecting cam slots symmetrically arranged in a closed loop around a central axis, and a follower pin movable within the slots to effect a rotary movement of the cam member in stepped increments in a predetermined forward direction. Each of the cam slots is of decreasing depth in the forward direction of rotation of the cam member such that at each juncture of one slot with the next, the end point of the slot traversed is higher than the starting point of the next slot in the forward direction to thereby define a shoulder between the two slots blocking the return movement of the pin in the traversed direction and constraining its movement only into the next slot in the forward direction of rotation.Also described are valve constructions including the steppable mechanism for actuating the valve at a predetermined step thereof.

  • Patent number: 4200180
    Abstract: A transfer finger for feeding small workpieces is pivotally mounted at the forward end of a rod which is adapted to be advanced and retracted by a reciprocating pneumatic actuator. During the initial portions of the advance and retract strokes of the actuator, one or more radially contractible collects frictionally grip the rod and prevent the rod from advancing and retracting the finger until such time as the actuator has pivoted the finger between active and inactive positions.

  • Patent number: 4103120
    Abstract: Disclosed is an auxiliary mechanism for rapidly imparting rotational energy to electrical switch components. An insulator connects an electrical switch component to an output shaft mounted for rotation in the mechanism housing. A lever arm assembly is mounted on the shaft and a link member is pivotably connected between the lever arm assembly and a first arm extending from a bellcrank member. The bellcrank member is mounted for rotation in the housing and has a second arm that is operably connected to one or more solenoids. Initially the link member and first arm are in an overcenter toggle position so that the insulator cannot be accidentally rotated. Energization of the solenoid causes rapid rotation of the insulator because the mechanical advantage of the system in such that maximum force is applied initially.
