Title: Flexible Metallic Sleeve or Hose
IPC: F16L11/16
Filed: 1979-01-12
Abstract: A flexible metallic sleeve or hose 1a is formed by helically winding a profiled metal strip 2 with the side edges of adjacent turns of the strip interengaged. The profile of the strip changes along its length so that, when helically wound, in one peripheral region 3 of the hose 1a transverse relative movement of adjacent turns of the strip is prevented whilst in another peripheral region 4 of the hose 1a transverse relative movement is permitted, whereby the hose 1a is free to bend in one direction but not in another. The profiled strip 2 is preferably formed by passing a plain metal strip 18 between rotary rolling dies whose circumferences correspond exactly to the length or to a multiple of the lengths of one turn of the strip in the hose, the profiles of the dies change over the circumference thereof in accordance with the required variations in the profile of the strip 2. In a modification, the strip is replaced by separately formed annular sectional units which are secured together. <IMAGE>

Title: Producing fibre reinforced plastics tube
IPC: D04H18/00
Filed: 1979-04-30
Abstract: A method and apparatus for continuously producing fibre reinforced plastics tube has a section "A" in which a fibrous sheet 1 is spirally wound into a cylindrical tube 1A on a tubular needling mandrel 3 by which the walls of the tube is needled to provide radially interlocking fibres. The needled tube is longitudinally displaced into a section B where it passes over a support mandrel 3D. The mandrel 3D includes a distributor head 9 by which resin is applied to the inner surface of the tubular wall 1a to impregnate the fibrous tube until such resin is visible on the outer surface of the tube. Following impregnation, a protective coating 10 is spirally wrapped over the outer surface of the tube as the tube passes into a section "C" having heaters 13 by which the resin is cured. The cured tube 1B emerging from the heaters 13 can pass into a section D where a saw 15a which is movable longitudinally in unison with the tube can part-off pieces of the tube (as may be required for plain cylindrical bearings). <IMAGE>

Title: Video display control apparatus
IPC: G09G5/34
Filed: 1979-07-11
Abstract: Video display control apparatus for a visual display device (11, Fig. 1, not shown) employing a television- type raster in a word processor has a display memory (13), a column counter 25 and a row counter 28 adapted to address the display memory. Each location of the display memory has an address comprising a column number and a row number. A clock oscillator (18) and a timing chain (19) produce raster timing signals and column and row timing signals. The count in the column counter 25 tracks the line being scanned, and the count in the row counter tracks successive groups of lines in the raster. The display data output of the display memory controls a character matrix memory (15) acting through a parallel-to-serial converter (16) to cause alphanumeric characters to be displayed in rows by the display device. So that the information display by the display device can be varied in a convenient manner, the row counter 28 is coupled to the display memory 13 through a random access memory 30 which stores information from a central processor unit (14). This stored information determines which set of sequential row addresses shall be supplied to the display memory as the row counter 28 carries out its counting sequence, and includes an instruction associated with a selected row address which causes a reset signal 31 to be supplied to the column counter 25 so that for this row the characters displayed start at the character stored in the first column of locations in the display memory, the column addresses generated by the column counter 25 being otherwise selectable as any set formed by a predetermined number of consecutive column addresses for alphanumeric character locations in the display memory. <IMAGE>

Title: Depositing material by vacuum evaporation
IPC: C23C14/24
Filed: 1980-09-23
Abstract: A method and apparatus for depositing material (e.g. CdS) on a continuously moving substrate by vacuum evaporation, particularly in the manufacture of photovoltaic cells. The substrate (27) is passed adjacent an array of nozzles (26) of a manifold within an evacuated coating chamber (29), and the material to be deposited is vaporized by heating it in a substantially enclosed evaporation chamber (10, 11) communicating with the manifold through a restricted diameter orifice (22). The rate of deposition is controlled by the pressure difference between the evaporation chamber and the manifold, the pressure difference itself being controlled by the heat input to the evaporation chamber. Upon exhaustion of evaporant material is one evaporation chamber (10), a second evaporation chamber (11) having more material is automatically applied to the manifold through the same orifice without interrupting the vacuum in the coating chamber, the automatic application being initiated in response to the temperature of the first-mentioned evaporation chamber. <IMAGE>

Title: Apparatus for Recognising Handwritten Signs
IPC: G06K9/00
Filed: 1980-10-24
Abstract: Signature recognition by electronics has previously required large storage capacity and has had rates of rejections of true signatures and acceptances of false signatures which are not entirely satisfactory. In apparatus for signature recognition a signature written on an input tablet 10 is segmented by detecting zero slopes in a waveform corresponding to the signature using a differentiator 12 and a zero-crossing detector 13. Feature signals derived from the waveform from input tablet 10 and held in RAM 23, corresponding to one or more characteristics of a limited number of segments, for example the first twelve, are correlated against previously obtained reference values, held in RAM 35, by moving signals in RAM 23 to different locations but always comparing the contents of the same pairs of locations which correspond to respective segments until an error obtained is below a predetermined level or failing this, the error is a minimum. After correlation has been carried out the feature and reference signals for corresponding segments are compared using the microprocessor system 24 to provide a decision on whether to accept or reject the signature. <IMAGE>
