Filed: 1987-03-10
Abstract: A helical spacer (12) is slid onto a cylindrical 
mandrel (38) and a flexible corrugated ribbon (T) of 
plastically deformable packing material, especially 
expanded graphite, is helically wound onto the mandrel 
(38) between turns of the spacer (12). This assembly 
is placed in a tubular die (14) and tubular punches 
(28) are run into the die (14), and moved axially 
towards one another telescopically of the mandrel (38). 
The punches (28), engaging opposite turns at ends of 
spacer (12) axially compress and radially expand the 
helix, raising its density. The helical packing stock 
(GSP) is disassembled from the spacer (12) and mandrel 
(38) by rotation, and supplied to the trade. In use, 
some of the stock is telescoped onto a valve stem, or a 
mandrel of the same diameter as the valve stem, and cut 
to length, eg. using a pen knife. In this way, one 
stock of packing material can serve valve stems of a 
range of sizes.

Title: Method for reducing the image data of digital television signals
IPC: H04N19/61
Filed: 1988-03-22
Abstract: This method comprises a preprocessing of the signals by means of a block-by-block transformation method, in which preprocessing both a transformation and the formation of a difference between a signal which is generated at a time t-1 and has been stored in a frame buffer and a signal which is produced at a time t are carried out so that the preprocessing forms a transformed frame-to-frame prediction error signal, the prediction error signal thus formed being subjected to a scalar quantisation, a number ND being determined from the quantised prediction error signal which corresponds to the parallel of the secondary diagonal in a coefficient matrix up to which, starting from a direct component, significant coefficients are contained and which number is used for reducing the number of coefficients to be transmitted, which number ND is also transmitted. The prediction error signal is also subjected to a vector quantisation and the representative block selected by this means is indirectly transmitted by means of its index which represents its address in a code table. The representative block is subtracted from the quantised prediction error signal in order to achieve by this means a reduction in the energy of the signal to be transmitted. <IMAGE>

Title: 3-dimensional vision system utilizing coherent optical detection
IPC: G01B9/02
Filed: 1988-03-11
Abstract: A three-dimensional optical scanning vision system capable of producing high-resolution images in real-time includes an optical source (100) for producing a source light beam. The source light beam is directed to a beam splitter (104) which splits it into a local oscillator beam and a signal beam. The local oscillator beam is directed toward a photodetector (106), while the signal light beam is directed toward a target (112). Light reflected from the target (112) is received by the beam splitter (104) and directed toward a retroreflector (118) which returns the beam to the beam splitter (104) interface. Quarter wave plates (110,116) and the retroreflector (118) insure that the return light beam and the local oscillator beam are collimated and have the same polarization state. Mixing the local oscillator beam and the return light beam occurs at the beam splitter (104) interface, thus providing coherent optical detection by the photodetector (106). The photodetector thus provides an output signal providing a high degree of information about the target. The system also includes scanner optics (2) to scan the signal light beam across the target. A processor (20) is also included for outputting a three-dimensional image of the target, and for controlling the scanner optics (2).

Title: Apparatus and method for the production of oxides of lead
IPC: F27B9/06
Filed: 1989-10-16
Abstract: A furnace for producing oxides of lead includes an 
enclosure defining a furnace chamber, a feed inlet for 
feeding particulate lead into the chamber, and a discharge 
outlet for discharging the particulate lead outside the 
chamber. An array of horizontally disposed serially 
communicating tubes are arranged vertically within the 
chamber, communicating between the feed inlet and the 
discharge outlet. A rotating valve is associated with the 
feed inlet, for continuously feeding particulate lead into 
the number of tubes. Variable drive chain and sprocket 
combinations are associated with each of the tubes to convey 
the particulate lead serially along the tubes. The furnace 
includes electric heat tapes surrounding the tubes, for 
heating the particulate lead within the tubes while the lead 
is being conveyed along the tubes. The furnace can be used 
to produce red lead from leady-oxide or litharge by first 
supplying air or pure oxygen into the tubes. Leady-oxide is 
supplied at feed inlet and heated in the first tube to 
1250°F to initiate the exothermic conversion of leady-oxide 
to litharge. Heat from the exothermic reaction occurring in 
the remaining tubes of the array is used to pre-heat the 
first tube. Litharge formed from the exothermic reaction is 
exposed to a lower temperature of 850° in the lowermost 
tubes of the array for formation of red lead. The travel 
rate of the litharge determines the percentage of red lead 
in the final product exiting the discharge outlet.
