Abstract: A system for retrieving information on a random basis from a disc having the information thereon in a spiral path around the disc. The system includes a turntable rotatable about a central spindle and adapted to support the disc thereon. An arm housing is fixedly mounted over the turntable and contains printed circuit boards having some of the electrical circuitry for the system. Also in the arm housing is a rectangular frame like cartridge holder which supports a cartridge having a stylus therein. The stylus is adapted to ride on the disc to read out the information from the disc. A piston is connected to the cartridge holder and extends through the arm housing. A motor is connected to the piston and is adapted to move the piston so that the cartridge holder is moved with respect to the arm housing and the stylus moves radially along the disc. The motor moves the stylus over the short distance of the radius so as to quickly and easily obtain random access to the information in the disc.

Abstract: A system and method is provided to transmit logmap video images through telephone line band-limited analog channels. The pixel organization in the logmap image is designed to match the sensor geometry of the human eye with a greater concentration of pixels at the center. The transmitter divides the frequency band into channels, and assigns one or two pixels to each channel, for example a 3KHz voice quality telephone line is divided into 768 channels spaced about 3.9Hz apart. Each channel consists of two carrier waves in quadrature, so each channel can carry two pixels. Some channels are reserved for special calibration signals enabling the receiver to detect both the phase and magnitude of the received signal. If the sensor and pixels are connected directly to a bank of oscillators and the receiver can continuously receive each channel, then the receiver need not be synchronized with the transmitter.

Abstract: An indicating lamp unit or the like is mounted on a wall of a motor vehicle body through mounting pins carried by the lighting unit and carrying retaining means which fit in holes formed in the body wall. Each mounting hole in the body wall is of banjo shape, having a first part through which the retaining means can freely pass and a narrower second part which hold the retaining means securely when the lighting unit is moved sideways. Each of the said retaining means comprises a retaining ring having a peripheral groove defining a middle zone bounded by a pair of generally transverse flanks, which engage on either side of the narrow second part of the mounting hole so as to retain the retaining ring to the wall against movement in either longitudinal direction.

Abstract: A contact lens cleaning and disinfecting system is formed as a compact unit with an upper housing portion containing a UV lamp and a lower base portion containing a cleaning/disinfecting chamber which is filled with saline solution, a lens holder, a turbulence mechanism for inducing turbulence in the fluid, and an electronic control unit for operating the UV lamp and the turbulence mechanism in a single cleaning/disinfecting cycle of comparatively short duration. The lens holder has a pair of lower lens holder portions for the lenses and an upper bracket for shading the lenses from direct UV radiation. The turbulence mechanism is a magnetic pedal, tethered on the end of a flexible spring, which is driven by a magnetic flux generator to create a whirlpool in the fluid which swirls in and around the lens holder portion. Particles, films, and other deposits dislodged from the lenses are carried by the whirlpool above the upper bracket of the lens holder where they are disinfected by the UV radiation.
