Title: Catv signal distribution system using optical fibers
Inventor: SUZUKI SYUJI
IPC: H04B10/54
Filed: 1991-06-14
Abstract: ABSTRACT            Disclosed is a CATV distribution system using optical signals and allowing each subscriber to use an existing CATV system which is implemented with coaxial cables.  The system comprises a transmitter means for providing a multiplexed TV signal in the form of an optical signal, a plurality of receivers owned by subscribers and an optical transmission path inter-connecting the transmitter and the plurality of receivers.  The transmitter comprises amplitude modulators for subcarriers each having a particular frequency and assigned one-to-one to the plurality of TV signals to produce a plurality of amplitude modulated (AM) signals.  The plurality of AM signals are multiplexed to output a frequency multiplexed (FDM) signal.  A main carrier having a predetermined frequency is frequency modulated by the FDM signal to produce a frequency modulated (FM) signal.  An optical-to-electrical signal converter converts the FM signal to a corresponding optical signal and outputs the optical signal.  Each receiver comprises an optical-to-electrical signal converter for receiving the optical signal and converting it to an FM signal, an FM demodulator for demodulating the FM signal to output an FDM signal, a selector for receiving the FDM signal, selecting any one of the plurality of AM signals constituting the FDM signal, and outputting it as a selected AM signal, and an AM demodulator for demodulating the selected AM signal to output the selected AM signal as the selected TV signal.

Title: Method and apparatus for making sausages
Inventor: STAUDENRAUSCH GEORG
IPC: A22C11/02
Filed: 1991-06-25
Abstract: Abstract of the Disclosure The invention relates to a method and apparatus for making sausages, in which the sausage meat provenient from a supply container is filled into the sausage skin pulled off a skin caterpillar, and the thus obtained sausage rope is divided into individual sausages by twisting it between each two adjacent sausage portions.            Dividing a sausage rope in this manner by twisting involves the danger of the sausage skin being damaged. The twisting operation also requires a relatively great amount of sausage meat to be displaced from the dividing location, resulting in the creation of strongly deformed sausage ends.   according to the invention these disadvantages are avoided by the provision that the spacing beween each two adjacent sausage portions is increased by pulling the leading sausage portion forwards together with the sausage skin at a speed greater than the sausage meat expulsion speed during the dividing operation.

Title: Road gritter device
Inventor: COTTON WILLIAM F
IPC: E01C19/20
Filed: 1990-03-08
Abstract: There is disclosed a road gritter device (10) which forms a unit which can be mounted onto a loading platform (11) of a truck for use during the winter months, and which comprises a hopper body (12) assembled from a number of separately formed plates of rigid plastics material which are releasably coupled together for replacement when required. An endless conveyor (15) is arranged to convey gritter material from the hopper body (12) to a spinner disc assembly (13) which comprises a spinner disc (14) rotatable in a substantially horizontal plane in order to distribute laterally gritter material supplied thereto. The endless conveyor (15) has an endless conveyor band (16) made of plastics or elastomeric material, and preferably also the spinner disc (14) also is made of plastics material. Therefore, the major components of the road gritter device are made of plastics material which is not adversely affected by usual road gritter material incorporating "salt", which otherwise can cause serious corrosion damage to existing designs of gritter devices fabricated from metal sheet and having metal spinner discs. By making the hopper body of an assembly of separate rigid sheets or plates of plastics material, damaged or worn sheets can readily be replaced.

Title: Method and apparatus for shuffling and deshuffling data
Inventor: SMIDTH PETER
IPC: H04N7/30
Filed: 1991-12-27
Abstract: ABSTRACT OF THE DISCLOSURE In a data compression process such as employed to compress video or other data, it is preferable not to compress the image data representative of the video image in a sequential format, or to take the data from the same area of the image. To equalize the information content of the data prior to compression, thepresent shuffling/deshuffling technique divides the video image into a multi-tude of image representing blocks, and selects a predetermined number of the image blocks from different spatial locations in the image, to form a succession of data sets representative of the video image information. That is, the selection of the image representing blocks is such that the information content (complexity) in each data set is similar to the information content in each other data set and further similar to the average information content of the entire video image. Thus, the subsequent quantizing factor used in the compression process will tendto be similar for successive data sets, thereby reducing any distortion introduced by the compression process. The image representing blocks may be formed of sequentially scanned blocks of the video image, or of transform coefficients repre-senting similar blocks of the video image. The shuffled data is deshuffled by the inverse process.
