Patent CA-2038043-A1 (CA)
Inventor: KRAUSE EDWARD A
IPC: H04N7/50
Filed: 1991-03-12
Abstract: The compression of successive blocks of digital data is optimized by selecting between different compression algorithms or different data formats on a block-by-block basis.  In one application, digitized interlaced video signals are processed for transmission in a compressed form.  A set of pixel data presented in a field format is compressed to provide a first compressed video signal.  The set of pixel data is also presented in a frame format and compressed to provide a second compressed video signal.  Errors are evaluated in the first and second compressed video signals.  The compressed video signal having the least error is selected for further processing.  The technique is repeated for successive sets of pixel data and the selected signals are encoded to identify them as field formatted or frame formatted signals.  The encoded selected signals are then combined to provide a compressed video signal data stream for transmission. Apparatus for receiving and decoding the signals is also disclosed.

Title: Apparatus for admitting metered quantities of liquid into bottles or other containers
Inventor: WALUSIAK JACEK
IPC: B67C3/28
Filed: 1991-03-28
Abstract: ABSTRACT           Apparatus for filling successive containers with a liquid, such as a carbonated beverage, has a rotary vessel with a bottom wall which carries an annulus of tubular extensions each of which is surrounded by a metering chamber.  Each extension and the associated metering chamber supports a filling unit with a twin-seat valve having a single valving element which is movable between an upper position to seal an outlet at the lower end of the extension from an adjacent inlet of the metering chamber while permitting the outlet of the metering chamber to discharge a metered quantity of liquid into a container below the filling unit, and a lower position in which the single valving element seals the outlet of the metering chamber but permits the extension to admit liquid into the metering chamber.  The mechanism for moving the valving element between its upper and lower positions independently of the speed of the vessel employs a spring which biases the valving element to its upper position when the underside of the valving element is acted upon by atmospheric pressure, and a mechanical flip-flop which can lower the valving element against the resistance of the spring.  Flow restrictors are provided to limit leakage of the liquid during movement of the valving element between its positions.

Preferably a plurality of such columns is inter-connected  to  a  closed  circuit,  so that  in  a cyclic succession these columns can be connected to the adsorption process or the regeneration  process.  The columns  can remain stationary in this process. The adsorbed caffeine is desorbed and, as a by-product, can be  used  for other purposes.

Title: Air intake filter for internal combustion engines
Inventor: VOLKER ERNST
IPC: F02M35/04
Filed: 1991-09-30
Abstract: Abstract An air intake filter for internal combustion engines has a flat, replaceable filter insert 20, through which the air flows transversely in operation, and which has a gasket 22 disposed on the periphery for sealing at the face side against a ledge 15 of the filter housing 11.  The insert can be inserted into the filter housing through a narrow side, the sealing pressure being produced by a cover 50 which has two sliding wedges 51 and 53.  To bring it about that, when the sealing pressure is applied, the gasket 22 will not be shifted laterally with respect to the ledge 15 of the filter housing  11,  the  cover,  which  is  in  the  form  of  a substantially  open  frame,  replaceably  accommodates  the filter insert.  The cover is provided with cams 40 and 41 which serve to fix the frame 30 in an extended position during the replacement of the filter insert.   Also the lateral walls 25 and 26 of the filter housing and the lateral walls 45 and 46 of the frame 30 are inclined wedge-wise to avoid large frictional forces between the adjacent surfaces when the filter is installed and removed.

Title: Carrier unit for terminal strips of a distribution frame in a telecommunications system
Inventor: KNOLL RUDOLF
IPC: H02B1/20
Filed: 1991-12-17
Abstract: ABSTRACT          The carrier unit that is formed from an essentially U-shaped extruded profile incorporates projections that are continuous in the longitudinal direction.  These can be used as screw, clamp, snap and plug channels for the attachment of functional elements that go to make up such a distribution unit.  In order to provide for the attachment of the terminal strips, the multi-functional extruded profile has at the edge of one arm a completely cylindrical shape and, on the edge of the other arm of the U, a screw channel.  The terminal strip is installed with corresponding hollow cylindrical cut-outs on the fully cylindrical moulded edge that forms a point of rotation and, on the opposing side surface, the flange that is formed thereon, by means of a screw connection.  Because of the point of rotation, simple installation of the terminal strips is possible and even in the case of a fully installed cross-connection system it is possible to pivot [the terminal strips] during fault-finding sequences or in the event that repairs are necessary.

Title: Methods for locating oil or gas deposits employing earth surface temperatures
Inventor: FONS LLOYD C
IPC: G01V9/00
Filed: 1992-10-01
Abstract: A method for predicting the likelihood of encountering oil or gas deposits below a location and determining the areal extent and magnitude (economic value) of such deposit. The earth's surface temperature at selected points within a location is compared to the earth's surface temperature at a plurality of paints in the surrounding geographic area to determine locations having anomalously low surface temperatures which are indicative of the presence of oil or gas deposits. Representative earth surface temperatures for all locations under consideration and reference temperatures in the geographic area are obtained, under similar ambient conditions, at points having similar topography, vegetative cover and surface features for minimizing extraneous factors which affect earth surface temperature, such that the earth surface temperatures may all be compared with each other to determine locations which have low earth surface temperatures, and therefore are more likely to have oil or gas deposits beneath them. The magnitude of the temperature difference between a location having low temperatures and the representative temperature for the geographic area as a whole is indicative of the thickness and area of an oil or gas deposit below the location.
