Title: Tab inserters
IPC: B65H35/07
Filed: 1980-08-01
Abstract: A tab inserter severs a tab from a strip 3 advanced along a guideway 4 before moving the tab to a position for insertion into a stack of sheets or onto a moving web. The inserter carries a pivotally mounted device 9 which is automatically pivoted by means of solenoid 15 firstly about a horizontal axis 11 to cause a roller 23 carried by plate 18 to frictionally engage the strip 3 and press it against a die 6 where it is cut by knife 5, the device 9 then automatically being pivoted about vertical axis 17 such that the friction between the roller and the tab drags the tab out from under the die until its end is positioned in the insertion position. The guideway may extend beyond the knife 5 and die 6 and be provided with an anvil at its end, in which case the device 9 is mounted for pivotal movement through 180 DEG  in each direction, and presses the outer end of the tab against the anvil. <IMAGE>

Title: Fume cupboard
Inventor: MCNAB GILBERT VICTOR
IPC: B08B15/02
Filed: 1983-10-26
Abstract: A housing 10 encloses a work space 19 and incorporates a door 26 which is opened to gain access to the work space 19. A duct 37 leads from the work space to an air extraction fan 39. The speed of operation of the fan 39 and thus the volume rate of air extraction is controlled by a signal from an inverter drive unit 45, said signal indicative of door position received by the unit 45, e.g. from a potentiometer 43 acted upon by the movement of the sash cord of the door 26. Thus the volume of air extracted varies dependant on door position so that the rate of air flow across the work space remains substantially constant at all positions of the door. <IMAGE>
