Title: Method and apparatus for forming a stack of generally flat articles from a shingled stream
IPC: B65H29/16
Filed: 1979-03-09
Abstract: Flat articles, for example packets (10) of dehydrated soup to be packaged as a stack in a display carton for retail sale, are passed in shingled relation along a generally horizontal conveyor (13), and discharged in succession into an open-topped receptacle, e.g. a carton or a trough (11) associated with a stack removal pusher, located at or beyond the downstream end of the conveyor so as to form a stack of vertically superimposed articles. Because of the close spacing of the articles as they fall into the receptacle, any disorientation of an individual article sufficient to prevent it from adopting its required position and attitude on the stack is prevented by the articles succeeding and/or preceding it. Spaced batches are defined in the article stream by a restraining hook (31), by an accelerator conveyor raisable through the conveyor (13), or by relative movement of the conveyor (13) and an upstream conveyor (12).   <IMAGE>

Patent GB-2069202-A (GB)
Title: Apparatus for performing a statistical analysis of a number of measurements
IPC: G07C3/14
Filed: 1980-02-02
Abstract: The apparatus produces a display, e.g. a printout, including a histogram built up of symbols, showing the distribution of measurements throughout a predetermined band divided into contiguous sub-bands. Prior to producing the histogram, the apparatus ascertains the largest number of measurements in any individual sub-band and divides this number by a figure representing the maximum possible number of symbols in a sub-band to obtain a third number. Each symbol of the histogram is made to represent an integer which is higher than the third number, preferably the next highest integer, thus ensuring that the histogram is of an easily interpretable shape irrespective of the number of measurements. The limits of an acceptable tolerance band are marked on the histogram. Individual measurement values are also displayed. Measurements falling above the tolerance band are distinguished by an H and those falling below are distinguished by an L. Measurements falling outside the displayed band are distinguished by a star.

Patent GB-2078049-A (GB)
Title: Display of visual information
IPC: H04N5/272
Filed: 1980-06-17
Abstract: In order to avoid obscuring an image (e.g. Figure 1a) on for example a cathode ray tube display when a symbol (e.g. Figure 1b) is superimposed on the image, the symbol is perceptually transparent (Figure 1c). A circuit for combining a background signal VB and a symbol signal VS (shown in Figure 3) operates according to the equation Vo = VB (1 - aVS) + bVS where 1>a>b>0. The multiplier VB (1 - aVS) diminishes the value of the background signal VB over the area of the symbol VS as if by the effect of perfect transparency. The added signal bVS gives the effect of a perceivable transparency by ensuring the symbol does not disappear as the background approaches black. Contrasting edging may be added around each symbol. <IMAGE>

Title: Improvements in manufacture of self-adhesive materials for stamps, labels or the like
IPC: G09F3/02
Filed: 1980-09-06
Abstract: In producing laminated material for self-adhesive stamps or labels which are stripped from a backing, the backing is coated with a release agent and the adhesive which is dried until it is at least touch dry.

By this method, the face layer can be perforated prior to application to the backing and cockling or buckling of the face layer is avoided. This is in contradistinction to the conventional prior methods in which the adhesive is applied to the face layer.

IPC: G05D16/20
Filed: 1981-02-13
Abstract: The pressure and the rate of change of pressure in a pressure vessel 4 supplied by a compressor 1 are measured and the compressor is regulated by switching it at an upper and a lower limiting pressure. The lower limiting pressure in the event of a rapid fall of pressure in the pressure vessel is arranged to be higher than that for a slow pressure fall, so that the delay which elapses before recommencement of delivery does not result in a drop below the bottom switching pressure. The upper limiting pressure is similarly lowered in the event of a rapid rise of pressure.
