Title: Apparatus for detecting tape on sheets
Inventor: CHAPMAN CHRISTOPHER PAUL
IPC: G07D7/12
Filed: 1982-08-09
Granted: 1987-08-20
Abstract: Apparatus is disclosed for detecting the presence of shiny tape on a printed note, for example a banknote. An optical fibre fishtail array supplies visible light from a source (A) to a lengthwise strip of the banknote. A first array of photodetectors (D) detects light specularly reflected from a plurality of adjacent regions of the said strip, while a second array (B) arranged parallel to the first array (D) detects light reflected diffusely from corresponding ones of the said regions. An analysing circuit receives signals from the photodetectors and indicates when the ratio of specularly reflected light from an illuminated element of the banknote to diffusely reflected light from the same element exceeds a predetermined value.

Filed: 1983-09-30
Granted: 1989-02-02
Abstract: In post and runner type scaffolding, a uniquely formed integral connector is created from the end of the runner or other similar cross-member. The integral connector secures to a scaffolding post bracket (preferably in the form of a ring flange concentrically affixed to said post and having a circular array of identical cutouts) and abuts forcefully against the convex surface of said post by means of a wedge acting through one of said cutouts. The connector has a longitudinally extending cross-slot in its end of a width and depth to accommodate the bracket therein, dividing the connector end into upper and lower limbs. The free end of each limb terminates with the tubular walls thereof reformed from the tubular shape of said cross-member to a shape (preferably more flattened) effective to strengthen and stiffen said limbs for their intended use of supporting scaffolding loads and connection stresses. A hole is formed in each limb so as to be adapted to align generally with any one of the cutouts in said bracket to accommodate said wedge.
