Abstract: IMPROVED SKID CONTROL SYSTEM           Abstract of the Disclosure:  A skid control system is provided for use with a vehicle having a pair of spaced apart wheels and having a braking system for applying braking forces to the wheels.  A brake control circuit responds to a skid signal obtained from any one of a plurality of in-cipient detector circuits to act upon the braking system to release the braking forces.  A delayed skid signal is provided whenever the difference in wheel speeds of the two wheels exceeds a given amount.  A delayed skid signal is also provided if the average wheels speed of the two wheels de-creases at a rate greater than a desired decreasing rate. If both wheels decelerate, a skid signal is provided upon sensing that the faster wheel is decelerating at a rate greater than a reference rate.  As the wheels spin-up toward an ideal velocity for a braked vehicle, an accelera-tion detector serves to insure wheel roll up on low friction surfaces.  If the wheels spin up at an acceleration greater than an acceleration level, the acceleration detector output is inhibited.  If the acceleration is less than the preceed-ing level and more than a second level, a skid signal is provided.  Also, as the wheels spin-up to a desired velocity, braking forces are restored when the rate of acceleration declines below the second acceleration level.  Monitoring circuits are provided for monitoring various operations of the skid control system and deactivate same when the operation is not within prescribed limits.

Abstract: ABSTRACT OF THE DISCLOSURE            A gasket of rubber or a similar material for sealing joints between the sealing surfaces of two members to be joined, for example pipe sections comprising a spigot and a socket part.          The gasket is placed in a fixed position on the sealing surface of one of the members, and for assembly of the members the sealing surfaces of both members are displaced substantially parallel to each other fox squeezing the gasket therebetween due to displacement of portions of the gasket relative to other gasket portions. The gasket portions which during the installation of the members are displaced relative to each other define one or more closed very narrow slits extending in the longitudinal direction of the gasket. The width of the slits is so small that the said gasket portions whilst being displaced during the installation are constantly in contact and slide along each other.          Further, the slits between the said portions of the gasket are so arranged that the said portions are displaced relative to each other during the installation without being bent, whereas the width of the gasket is reduced. When the said portions are displaced along each other in the opposite direction they become clenched and offer a large resistance to the displacement and produce a large packing pressure.

Abstract: ABSTRACT OF THE DISCLOSURE            A clamping circuit for color television signals includes a demodulator for demodulating the chrominance component of the color television signals to produce first and second color difference signals, and first and second adders for adding adjustable first and second control signals to the first and second color difference signals so as to produce modified first and second color difference signals.  A matrix circuit is responsive to the outputs from the first and second adders to produce a third color difference signal.  A reference signal, which represents a predetermined level of a color television signal, such as the pedestal level, is added to eac of the color difference signals; and a first comparator compares the first color difference signal with the reference signal added thereto, to the third color difference signal, with the reference signal added thereto, and a second comparator compares the second color difference signal, with the reference signal added thereto, to the third color difference signal, with the reference signal added thereto.  At the times of occurrence of the pedestal level of the color television signal, the outputs from the first and second comparators are sampled, respectively, to produce the first and second control signals which are fed back and added to the first and second color difference signals.   In one embodiment, the reference signal is a d.c. level proportional to the pedestal level of the color television signal. In another embodiment, the reference signal is the luminance component of the color television signal clamped to the pedestal level.  This clamped luminance signal is produced by another clamp circuit.

Abstract: Abstract of the Disclosure An optical position code detector which senses infor-mation that is recorded on a record carrier   The record carrier preferably has scan marks for synchronizing operation of the detector and at least one track with positionally encoded data marks which include one or more imprinted alphanumeric characters The detector includes photodetector which sense light that is reflected from the record carrier.   The intensity of the reflected light varies in dependence on whether or not data marks are present and also varies due to the presence of spurious marks on the record carrier.   When a scan mark appears, a comparison circuit is activated which compares the voltage from each photo-detector with a reference voltage which is cycled from a low magnitude to a relatively high magnitude   The comparison circuit distinguishes data marks from spurious marks with a high resolu-tion.   A logic circuit is connected to the comparison circuit to indicate whether or not a position code is present on the record carrier.   If a code validity detector which is connected to the logic circuit ascertains that a predetermined number of successive indications have been made by the logic circuit that the same position code is present, the position code is decoded to provide machine-useable information, such as to update payroll files in an attendance recorder system.

Abstract: ABSTRACT    A down hole well drilling tool, e.g., a turbodrill, which is connected to a string of drill pipe as a rotating shaft for driving a drill bit which may be a rotary bit or a high speed solid head diamond bit.  The turbine section has rotor and stator blades which are crescent-shaped in cross section.  The bearing shaft is provided with chevron rotary seals positioned below the rotary bearings carrying both radial and vertical thrust.  Fluid lubricant fills the space from the rotary seals to a predetermined level above the bearings.  A piston seals the lubricant chamber and is pressurized by drilling fluid (i.e., mud) flowing through the tool.  A layer of lubricant fluid over-lies the first piston and has a second piston covering said fluid and transmitting pressure from the drilling fluid to the lubri-cant fluid surrounding the bearings.  Means is provided to give an indication, at the well surface, of loss of lubricant in the turbodrill.  Means is provided to cause the vertical thrust to be carried on the bottom vertical thrust bearings, after the top vertical thrust bearings are worn, and thus extend the drilling life substantially.  Another optional feature provides for bal-ancing the pressure across the bearing seals.  This is accom-plished in one form of the invention by providing pump means operated by the drilling motor to pump drilling mud away from the bearing seals.  In another form of the invention, the flow of drilling fluid is divided into two streams, one of which rotates the drill bit, and the other of which passes through the drill bit.  The pressure drop across the drilling motor equals the pressure drop across the drill bit, thus balancing the pressure on the bearing seals.
