  • Patent number: 4736208
    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.

  • Patent number: 4736196
    Abstract: A system for monitoring the location of an individual is disclosed and includes a band to be strapped to the individual's wrist or ankle. A trigger, transmitter, and antenna are incorporated into the band. The trigger controls operation of the transmitter and activation is effected by a portable authority-retained control unit. The trigger deactivates the transmitter under predetermined conditions (such as removal of the band) and reactivation requires utilization of the control unit.

  • Patent number: 4733983
    Abstract: A fillable toothbrush provided with a handle containing a dispenser for toothpaste is disclosed. One end of the handle is provided with a stem through which a duct is provided from a storage chamber to an outlet adjacent to a brush arranged at the free end of the stem. An actuating element is provided at the end of the handle remote from the stem. When actuated, the actuating element moves a valve that closes off the storage chamber from the duct and pushes toothpaste through the duct to the brush. When the actuating element is released, the valve retracts and permits toothpaste in the storage chamber to flow into the duct. The dispenser toothbrush is of simple design and allows defined quantities of toothpaste to be dispensed in a reliable way.

  • Patent number: 4733663
    Abstract: There is provided an improved rongeur having a jaw mechanism comprised of a barrel member having a honed cutting edge on one extremity thereof and having a shaft member located within and arranged for reciprocal motion. On the shaft member there is provided a plate member attached at one extremity to trap bone against the cutting edge. A lever mechanism is provided having paired handle levers joined by a pivot and having the barrel and shaft member attached to the handle levers between the handle portion and the pivot. On the shaft member there is further provided a cavity arranged to slide within the barrel progressively as the cutting operation proceeds, gradually drawing severed bone within the capturing cavity. Stop surfaces are located in the cutting area at a position relative to the cutting edge to avoid direct force contact on the cutting edge when the shaft member is reciprocated to its full extent within the barrel member.

  • Patent number: 4731554
    Abstract: A low profile ring-shaped motor has a housing, a bearing support attached to the housing and supporting a rotating shaft carrying a ring-shaped rotor. A ring-shaped stator is secured to the housing and is concentric and between the legs of the U-shaped rotor. The stator is formed by a continuous strip of magnetic material wound and laminated in a toroid and having helical windings therearound. 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.

  • Patent number: 4729451
    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.

  • Patent number: 4723599
    Abstract: In this heat exchanger, an improvement comprises the following. The fin plates each have louvered portions interposing the aligned openings in the fin plates. The louvered portions in each fin plate define a nominal plane and include a plurality of louvers and a base. The base has base portions including rise portions and flank portions, three each. The rise portions and flank portions alternate with each other in a transverse direction across the width of the fin plate. The rise portions and flank portions form three peaks, which are a central peak and two outer peaks. The peaks are raised in a first direction perpendicular to the nominal plane. The rise portions and flank portions further form two valleys in the opposite, second direction perpendicular to the nominal plane. The valleys are spaced from each other and are each between the central peak and an outer peak. The rise portions are substantially parallel to each other and intersect the nominal plane at a first acute angle.
