  • Patent number: 4948133
    Abstract: A gaming apparatus comprising a plurality of gaming machines is provided. Each machine can be operated individually, the player upon each start of the machine endeavouring to reach a predetermined objective by his skill in propelling a ball into apertures to reach a predetermined total before a counting device in the machine which is started upon starting of the machine, reaches that total. The player thus competes against the machine in individual operation thereof. In the embodiment described the counting device is a clock hand which sweeps across a clock face. The players performance is indicated by a clock hand sweeping across the same clock face. The clock face and both hands are visible to the player to provide excitement.All of the machines can be ganged so that the players play against each other, but in this case the counting devices of the respective machines are rendered inoperative and the winner is the first player to make his clock hand reach the predetermined total.

  • Patent number: 4936684
    Abstract: In a color measuring spectrometer employing a reflecting grating and a linear array of photodetectors for measuring different components of a spectrum, the width of the photodetectors varies throughout the length of the array. The width of each photodetector is selected so that each photodetector detects the same bandwidth interval measured in wavelengths.

  • Patent number: 4932779
    Abstract: In a color measuring instrument, an integrating sphere is used to illuminate the sample and fiber optics are used to carry light diffusely reflected from the sample and from an interior wall of the sphere to a spectrometer. The transmitting ends of the fiber optic bundles are fixed in the housing of the spectrometer as entrance slits for the spectrometer, which includes a fixed grating and one or two arrays of photodetectors to detect the spectra dispersed by the grating from light received from the two transmitting ends.

  • Patent number: 4916309
    Abstract: An appliance for converting an optical reflectance measuring instrument into a transmittance measuring instrument is shaped to fit in the aperture of a probe of the reflectance measuring instrument. When used as a reflectance measuring instrument, reflectance samples are positioned over the aperture. The appliance has a fiber optic cable which receives light from the probe and carries it out through the aperture and redirects the light back toward the aperture through a position designed to receive a sample, the transmittance of which is to be measured. In the optical instrument, the light received by the probe is carried by fiber optics to a spectrometer.

  • Patent number: 4910962
    Abstract: A compact master cylinder suitable, for example, for vehicle clutch or brake systems. An integral fluid reservoir body is connected to a piston stem extending to a piston head in the cylinder. The stem has a longitudinal passage connected to an orifice at the reservoir inlet. This orifice is valved by a valve closure member having a spherical head and an elastomeric cap. In the retracted state a stop secured to the cylinder limits movement of the piston out of the bore and the valve closure member opens to allow entry of make-up fluid from the reservoir.

  • Patent number: 4886355
    Abstract: In an optical instrument for spectroscopically measuring color and gloss of a sample surface, a fiber optic probe is provided wherein light is transmitted from a light source to the probe through a fiber optic bundle. The fiber optic bundle is arranged to illuminate a surface positioned over an aperture in the probe. Light diffusely reflected from the sample surface is transmitted by a second fiber optic bundle to a spectrophotometer. A small fiber bundle is arranged in the probe to irradiate the surface of the sample at an angle of 60 degrees and a second small fiber bundle is arranged to receive light from the first mentioned small fiber bundle after being specularly reflected from the surface. The second fiber optic bundle transmits the received light to a photodetector in the spectrophotometer to provide an indication of the gloss of the sample surface.

  • Patent number: 4743024
    Abstract: The machine is a coin operated gaming machine wherein at each play random number display devices is actuated a plurality of times and a number corresponding to the number displayed by the random display device at each actuation is illuminated in a display matrix of the machine containing all numbers, the objective being at each play to win by illuminating a row of numbers or the four corner numbers in the display matrix. Winnings are in the form of tokens dispensed from the machine and the tokens can be exchanged for gifts contained in a display case forming part of the machine casing.

  • Patent number: 4263554
    Abstract: A frequency discriminator having at least one ferrimagnetic resonator in a band pass or band reject configuration, the frequency of which is swept over a frequency band of interest, a detector receives the filter output, and the timing relationship between the detector output and the swept frequency is compared to generate the discriminator output. The discriminator has a bandwidth variable from a relatively narrow range to a very wide range in which the center frequency is simultaneously tunable over an extremely wide frequency range. The discriminator is insensitive to amplitude variations of the input signal and is capable of demodulating low level signals. The frequency discriminator is particularly useful for microwave frequency applications, for example, as a discriminator in a simple microwave FM receiver.
