Abstract: "Digital Video Communication System Having a Network Clock Source"                     ABSTRACT OF THE DISCLOSURE In a digital video communication system, a network clock source is provided to supply a common clock pulse synchronized with the transmission speed of the system to each station through a transmission channel to allow it to derive a video sync pulse. This sync pulse is applied to a video signal source to generate an analog composite television signal. A quantization sampling pulse is derived from the video sync pulse which is contained in the composite television signal to quantize the composite television signal. The quantized video signal is stored in a buffer and forwarded to a receiver station in response to the received network clock pulse, so that the quantization sampling rate and the transmission sampling rate of a transmitter station of the system are synchronized with each other. The sampling rate of the dequantization process at the receiver station is also synchronized with the transmission sampling rate.

Abstract: A decentralized communication arrangement is provided for a two way cable television (CATV) network wherein a node originating a message (a source node) and a node receiving a message (a destination node) can be located at any respective points in the CATV system. In one aspect, a source node transmits a message towards the headend of the upstream portion of the cable spectrum. The headend selectively rebroadcasts the upstream message in the downstream portion of the cable spectrum, thus providing an arrangement whereby a source node is able to transmit a message to a destination node, wherever located. Since, the CATV communication network is deployed to the general public, another aspect of the present system includes a mechanism by which the access to CATV communication resources is controlled so that unauthorized users are denied access and authorized users are granted access. In accordance with this aspect, a source node further transmits a verification message, referred to herein as a frame verifier (FV) code, as part of the upstream message. The invention further provides for the headend apparatus to examine the frame verifier code and rebroadcast the received upstream message in the downstream portion of the cable spectrum only if the frame verifier code indicates that the source node is an authorized user, thereby granting the user access to the CATV resources. Conversely, the headend apparatus does not rebroadcast the upstream message if the frame verifier message indicates that the source node is not an authorized user thereby denying the user access to the CATV resources.

Abstract: Type A, especially type 4A zeolites are well adapted as detergent builders, said zeolites comprising (i) primary particles having a mean particle diameter ranging from 0.1 to 10 mu , (ii) a cation exchange capacity in excess of about 100 mg CaCO3/g of anhydrous material, and (iii) a rate constant, relative to the surface area of the zeolite per liter of wash solution, in excess of about 0.15 s-1 lm-2. The builders are prepared by first determining the value of the rate constant for a given zeolite sample. Since a higher rate constant value corresponds to a lower degree of salt incrustation on fabrics, only those zeolites having a value above the predetermined minimum will be incorporated into detergents. Thus, zeolites otherwise appearing identical can be differentiated, with only those not causing high levels of incrustation being selected.
