  • Drawing toy
    Patent number: 4427387
    Abstract: Disclosed is a drawing toy which includes a plurality of light transmitting carriers that are manually movable past a writing platen which supports portions of the carrier. Each carrier has on its surface a series of different figure fragments which inhibit light from passing through the carrier where a figure fragment is displayed. Selectively moving the carriers to the platen positions different figure fragments over the platen. There is a light source adjacent to the platen and on the side of the platen opposite the carrier so that light passes through the platen and then through the carrier. Preferably, a transparent protective member overlies the portion of the carriers supported by the platen, with the carriers being sandwiched between this member and the platen. A translucent sheet of paper is placed over the protective member opposite the platen.

  • Apparatus for diagnosing abnormalities in rotating machines
    Patent number: 4425798
    Abstract: A portalbe apparatus is disclosed for the diagnosis of a rotating machinery utilizing a fast Fourier transform frequency spectrum analysis system. The presence or absence of an abnormality or trouble in the rotating machinery is determined by selecting high amplitudes out from the frequency spectrum computed by the FFT frequency spectrum analysis system, arithmetically processing distribution data of spectrum amplitudes adjacent each frequency giving the corresponding high amplitude, and detecting the amplitude, at which the frequency of vibrations of the rotating machinery has attained a maximum value, together with such frequency. The diagnosis of the rotating machinery with this apparatus can be performed in situ, i.e., at the site of installation of such machinery.

  • Motor drive circuit
    Patent number: 4404512
    Abstract: An inverter circuit for use in connection with loads such as motors and transformers is disclosed. The inverter includes separate precharge circuitry for precharging the commutating capacitor, clamping diodes for clamping the voltage on the inverter power elements to the precharge voltage level, and steering diodes for coupling the motor or transformer to the SCRs. The steering diodes allow the commutating capacitors to be charged to a precharge voltage level which is selected to be at least twice the maximum voltage to be applied to the load. The clamping diodes, by limiting the maximum voltage on the inverter power components, allows the use of components of substantially reduced voltage ratings. The precharge circuit provides reliable commutation at low motor speeds and voltage levels. Other embodiments and improvements are disclosed.

  • Ophthalmic device to diagnose the eye fundus
    Patent number: 4402325
    Abstract: The present invention provides an ophthalmic device to diagnose the circulation of blood in an eye fundus by producing a pair of plethysmograms for synchronized comparison. A pair of fiber optic conduits are attached to a coupler that can be sealingly affixed to the exterior surface of the cornea of an eye. The coupler can be attached to the exterior surface of the eye by the application of subatmospheric pressure within the coupler. Light is introduced on the axis of the pupil through a central light exit region that is physically small enough relative to a dilated pupil to prevent the reflection of light from the iris. The light reflected from the eye fundus is received in a peripheral light receiving region. The light signals are converted into electrical voltage levels that are ultimately used to produce a visual display of the plethysmograms.
