Title: Separator/folder bag machine
Inventor: HATCHELL PETER J
IPC: B65H35/10
Filed: 1991-11-04
Abstract: ABSTRACT OF THE DISCLOSURE A separator/folder bag machine for developing individual, folded, plastic bags.  A pair of high speed separation rollers, actuated by means of a servo motor driven eccentric linkage, engages a continuous plastic web to separate individual plastic bags formed in the web.  A pair of parallel, wide belts, and a pair of similar, overlying belts, engage both sides of the separated bags and transport the bags to a plurality of folding stations.  Air jets at selected locations in the folder/separator controllably direct the bags through pairs of nip rolls to fold the bags along predetermined fold lines.  Sensors in the folder/separator sense abnormal conditions and deactivate particular fold stations to reject improperly formed bags.  A two speed slowdown mechanism at the discharge end of the separator/folder slows the folded bags to facilitate downstream handling.  An optional stacker and indexing conveyor automatically stacks predetermined numbers of folded bags, aligns and compresses the bags to form an easily handled stack, and conveys the formed and compressed stack to downstream apparatus for further handling.

Title: Transmission and decoding of tree-encoder parameters of analogue signals
Inventor: MOULSLEY TIMOTHY JAMES
IPC: H03M7/00
Filed: 1992-01-06
Abstract: An analogue signal source (10) is coupled to an analysis means (12) to provide a plurality of parameters on a bus (14). The analysis means also provides a reset signal on a separate line (23) and both the bus (14) and the line (23) are fed to a tree coder (22). The reset signal is applied to the tree coder (22) before each parameter is applied on the bus (14) so that the coder commences from a known position in a coding tree for each parameter. The coded signals are supplied on a bus (24) to a modulator (28) having an output which is coupled to a transmitter (30). A system for recreating analogue signals coded in this way is also described which estimates partial values of parameters using the probability that each of the possible encoded sequences resulted in the signal from which the analogue signals are to be recreated. The recreating system may also use the probability of occurrence of each of the possible encoded sequences during the tree coding. This latter probability may be derived from the probability density function of the parameters. The tree coder may optionally be arranged to provide trellis coding, for example, for 8-PSK or 16QAM modulation.

Title: Method and apparatus for gas analysis
Inventor: KANITZ JUERGEN
IPC: G01N21/3518
Filed: 1992-03-31
Abstract: Abstract A Method and an Apparatus for Gas Analysis The present invention relates to a method and an apparatus for determining concentrations of substances in gases.  The method operates by electromagnetic irradiation and by measuring the intensity of the rays transmitted,  at a wavelength which is characteristic of the substance to be detected, wherein the gas containing the substance is measured at at least two different gas pressure values.  In order to overcome the drawbacks of the conventional methods which are carried out with reference gases which have to be produced and supplied expressly, but in order nonetheless to be able to quickly and easily determine the concentration of a substance in a gas with a relatively high degree of accuracy, it is proposed according to the invention that an initial measurement be taken at an initial, basically constant pressure of the gas to be analysed, and for the gas pressure to then be changed, and for a second measurement to be taken at a second constant gas pressure with an otherwise identical measuring arrangement,  and from the ratio of, or difference between,  the intensities measured when the two measurements are taken, the concentration of the substanceto be detected is ascertained in the gas by computer or using a graph, on the basis of a theoretical connection between the extinction and concentration by volume of that substance.
