Patent GB-2157032-A (GB)
Title: Digital parallel odder
Inventor: ELCE PHILIP JOSEPH
IPC: G06F7/505
Filed: 1984-04-06
Abstract: To add two binary numbers A & B in parallel the least significant bits of each number are added in a first sample period in adder unit 1, the output bits with carry being held in a latch 2. At the same time the most significant bits of each number are put through delays 3, 4 and added in unit 5 in a succeeding sample period, together with the carry from latch 2. The output bits in latch 2 are put through delay 6, so that they coincide with the outputs from unit 5. The input numbers are thus present for one sample period; two periods later the sum appears. Additions are performed at the full sample rate at the penalty of having the inputs delayed, whilst the internal carries have time to propagate right across the addition. <IMAGE>

Title: Apparatus for winding onto cores and separating the web
Inventor: PERINI FABIO
IPC: B65H19/28
Filed: 1985-01-28
Abstract: Web is wound onto cores which are introduced to the throat between first and second winder rolls (46,48) and which are advanced through the throat by causing the peripheral speed of second winder roll (48) to be slower than the peripheral speed of first winder roll (46). The web is guided around the first winder roll (46) and commences winding onto the core as it passes through the throat. A diameter control roll (69) acts on the web roll being wound and a differential speed control varies the peripheral speed of the diameter control roll (69) relative to the first and second winder rolls (46,48), eg to eject a fully wound roll between rolls (69 and 48) and separate the web. Alternatively, the speed of roll (69) is changed to cause the web roll to move the wound web roll towards a fresh core introduced through the throat, to trap the web between the fresh core and winder roll (48) and subsequently to separate the web. Perforating rolls (38,39) produce spaced lines of perforations across the web and the location of these lines can be varied by adjustment of the speed of rolls (38,39). <IMAGE>

Title: Manufacture of extrusion dies
Inventor: FELDCAMP EDWARD GEORGE
IPC: B29C48/12
Filed: 1985-12-18
Abstract: In the manufacture a steel die blank 5 is hardened prior to spark erosion of the die cavity 6a by wire- cutting technique. This is followed by spark erosion of a back clearance 7 using a graphite electrode 8 to provide the maximum bearing length "b" for the cavity. The graphite electrode 8 is then profiled so that it conforms to a determined overall bearing contour of the die to produce even flow through the die, after which the back clearance 7 is spark eroded using the profiled electrode 8 to produce substantially the correct bearing contour for the die. A test extrusion after initial back clearance erosion provides an end profile measured by a probe which supplies a CNC milling machine information to produce the desired electrode profile for the desired bearing contour. <IMAGE>
