Abstract: ABSTRACT OF THE DISCLOSURE TELEVISION TRANSMITTER COMPRISING A COMMON KLYSTRON FOR THE PICTURE AND SOUND       The klystron has a grid or another electrode for controlling the density of the electron beam, which receives a pulse signal, whose amplitude, duration and period are such that the klystron can supply a power equal to its peak power during the time intervals corresponding to the sync pulses of the picture signal and such that the klystron can only supply a predetermined fraction of its peak power for the remainder of the time, said fraction corresponding to the power to be supplied during the back porch of the picture signal. The variation of the klystron characteristic during the sync pulses leads to a variation in the amplitude and the group delay ofthe intercarrier signal frequency modulated by the sound and which itself modulates a UHF carrier. This is why correction means are provided on each sound channel, in order to compen-sate said amplitude variation and said group delay variation throughout the duration of the sync pulses.

Abstract: REFRIGERATOR DOOR HINGE                 ABSTRACT OF THE DISCLOSURE        The door-mounted water and ice cube dispenser of a refrigerator is supplied with chilled water and elec-trical power by a water conveying conduit and a plurality of electrical conductors which together pass through a hollow pintle and socket portion of a lower hinge assem-bly pivotally supporting the refrigerator door.  To facilitate removal of the door from the associated refrigerator cabinet, the lower end of the conduit is connected to an end of a chilled water supply line by a union type coupling, the lower ends of the conductors being connected to a plug engageable with an associated power supplying socket fixed to the refrigerator cabi-net.  The conduit and conductors extend upwardly from the lower hinge assembly to the dispenser location via the interior of an elongated, rigid, tubelike member that isolates the conduit and conductors from any thermal insulating material or other obstructions filling the interior volume of the door.  The tubelike member, by permitting unimpeded movement of the conduit and conduc-tors contained therein, precludes localized twisting and untwisting of the conduit and conductors at any specific point along their respective lengths to preclude fatigue breaks of the conduit or conductors resulting from repeated opening and closing of the door.

Title: Method and apparatus for detecting the collision of data packets
Inventor: SCHOLL FREDERICK W
IPC: H04L12/413
Filed: 1985-02-15
Granted: 1987-06-23
Abstract: ABSTRACT           Method and apparatus for detecting when a collision occurs between two or more binary data signal packets at a single binary data signal receiver.  Whenever a packet is transmitted, a large signal impulse is substituted for the initial bit of the packet.  The amplitude of the impulse is such that it is significantly greater than the highest binary signal level transmitted.  The receiver recognizes the impulse not as a data bit but as an indication of the beginning of a packet.  Every packet has a known duration (or packet period) and is separated from the next packet by at least a known gap period.  If two impulses are received within a period less than or equal to the sum of the packet and gap periods, a collision has occurred and a packet collision signal is generated.

Abstract: AN LED DRIVER CIRCUIT          Abstract A driver circuit turns an LED 'on' and 'off' in response to input logic 'one' and 'zero' data signals. A current regulator 11 is series coupled with the LED and serves to maintain a constant current to the LED over time, temperature, and supply voltage variations.  During turn-off, this current is shunted away from the LED by a low impedance emitter follower, operated in the active non-saturated region, and a small reverse bias potential is momentarily applied to the LED which quickly sweeps out the charge stored in the LED junction.  At the end of the 'off' cycle there is a forward probes potential across the LED. During turn-on, the current shunt is reverse biased and a current peaking circuit provides a momentary additional current through the LED.  This instantaneous forward current peaking and the forward probes both serve to substantially reduce the turn-on delay and rise time of the optical drive signal.  The current peaking and current shunting circuits are driven from the same differential amplifier.

Abstract: ABSTRACT      In a circuit arrangement for providing a current having a controllable temperature coefficient of current, a diffused resistor (334) is used to set up a reference current in a current source (40) which has a temperature coefficient dependent upon the diffused resistor.  A current mirror (352, 354, 356) receives the reference current and passes a portion of it through an ion implanted resistor (360).  The output current has a temperature coefficient which is a function of the original temperature coefficient of current and a nonzero algebraic multiple of the temperature coefficient of the implanted resistor.          By appropriate selection of the resistor values and types, the temperature coefficient of the output  current can be set to any desired value.

Abstract: METHOD AND APPARATUS FOR UNIFORMLY LOADING       PARTICULATE MATERIAL INTO CYLINDRICAL BEDS                         Abstract A method for simultaneously distributing catalyst particles across the full diameter of catalyst bed with a single rotor is disclosed.  The bed has substantially uniform high density by forming a multiplicity of annular rings of catalyst concentric with the vessel or bed center.  Such action is achieved without varying rotor speed by deflecting catalyst from a feed hopper into a plurality of arcuate sectors or portions of different radial lengths on a rotating disc.          Preferably, each arcuate portion  has a volume proportional to one of the annular areas of the bed within the cross-sectional area of the vessel.  The desired volume is formed by both the radial length of the arcuate sector and its included angle on the disc.         Depending upon the overall cross-sectional area of the vessel, the cylindrical volume of catalyst flowing from the feed tube may be divided into an outer annular column and an inner cylindrical column.  In a preferred embodiment this may be done by a frusto-conical member extending upwardly and inwardly into the feed tube from the main distribution surface of the disc.  Another plurality of separate arcuate flow paths of different radial lengths are rotated by the single rotor or disc.          Desirably, each other path is shorter than the radius of any of the arcuate portions formed by the disc.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved inertia sensitive seat hinge mechanism which enables the seat back to be normally folded forwardly to permit access to a motor vehicle rear compartment area which locks when exposed to a predetermined acceleration load.  The inertia sensitive actuator is in the form of a generally straight lever which is mounted  for rotation to the upper hinge structure.  A projecting finger of the inertia sensitive pendulum interacts with a cam surface associated with the lower recliner structure to maintain the inertia device in an engaged position when  the  seat back  is  in  its  rearmost  folded position.  This positioning improves reliability of the hinge device.          The configuration of components according to this invention eliminates the objectionable rearward projection presented by many present seat hinge designs which can  interfere with  free  access  to the rear compartment area.  The configuration further permits the mounting of an emergency release lever which is located close to the junction between  the  upper  and  lower  hinge  structures,  thus  simplifying trimming of the seat.  The hinge mechanism according to this invention is further extremely simple in configuration and operation.

Abstract: Esp. UF and MF resins, are added at 0. 05-1. 0% ( on resin solids) as aqs. soln. or solid to the amino resin. The curing agents are made by adding an equimolar amt. of N-methylethanolamine to 50% aqs. acetic acid or oxalic acid soln. The N-methylethanolamine (I) and di(N-methylethanolamine)oxalate (II) have high activity and give cured products with good abrasion and mar resistance and resistance to stress cracking (crazing). They are esp. useful in moulding powder and laminates; in the latter, the drying time of impregnated paper webs impregnated with resins catalysed with (I) or (II) may be reduced by 10-20% while giving the required degree of condensation compared with known catalysts. The pressing time e.g. for the surfacing of chipboard panels with impregnated overlays is reduced and the tendency to crack formation and porosity of the surface is reduced.
