Title: Emptying silos
Inventor: WILLIS BRIAN
IPC: B65D88/62
Filed: 1981-07-31
Abstract: An inflatable flexible substantially airtight plastics bag (16) is fitted inside a square-section (11) or round-section grain silo. The bag sits on the floor (12) of the silo in an initially collapsed and uninflated state. Elongate flaps (17) are heat- welded along the side walls of the bag and are bolted releasably to the inside walls of the silo to locate the bag positively but releasably in place. Grain entering the silo from above falls onto, and progressively builds up on top of, the bag. The majority of this grain falls under gravity through the grain outlet (13) when the silo is subsequently emptied. To empty the last remnants of grain from the silo, the bag (16) is inflated to assume gradually a cubic form and expand across substantially the whole cross-section of the silo to push the grain towards the grain outlet (13). <IMAGE>

Title: Sheet Stripping Apparatus and Method
IPC: G03G15/00
Filed: 1981-12-10
Abstract: A sheet stripping apparatus and method used in a photocopying machine employ a resiliently biased sheet stripping element (48) in contact with the photosensitive surface (15) of the copier for detaching a leading edge of a copy sheet (40) as it moves toward the sheet stripping assembly. A moving deflection surface, such as a knurled roller (64) is positioned immediately adjacent the operative portion of the sheet stripping element for deflecting the detached leading edge of the copy sheet away from the sheet stripping element and toward an exit path. A friction roller (74) in juxtaposition to the deflection surface provides a nip for grabbing the copy sheet and directing it along the exit path. The friction roller is preferably driven at a velocity greater than or equal to the velocity of the photosensitive surface. <IMAGE>

Title: Bias current compensated amplifier
Inventor: NAKAYAMA KAZUAKI
IPC: H03F1/32
Filed: 1983-02-17
Abstract: A class AB push-pull amplifier circuit comprising two amplifying element (Q1, Q2), in which, crossover distortion is largely eliminated, temperature compensation of idle current is obviated, and the idle current is maintained stable, independently of the magnitude of the input signal. In the embodiments, first and second error amplifiers (A<'>1 A<'>2) are provided each with three inputs. While the input is in one sense the first error amplifier amplifies the difference between a voltage from the output electrode of its associated amplifying element and a level-shifted voltage from the circuit input terminal (ie using inputs a c), the second error amplifier amplifies the difference between a voltage from the output terminal of its amplifying element and a level-shifted voltage from the circuit output terminal (ie using inputs a' b'). Alternatively when an input of the opposite sense is applied to first and second error amplifiers interchange operations (so the differences between a b and a' c' are amplified). The outputs from the error amplifiers are fed back as error signals as shown in order to control the bias. <IMAGE>

Title: Anchoring of rock bolts
Inventor: BYERS EDWARD VICTOR
IPC: E21D21/00
Filed: 1984-02-23
Abstract: A highly permanent anchorage to a blind hole in a rock formation capable of withstanding very heavy withdrawal loads utilises a circularly corrugated malleable metal tube 1 which is expanded to fit and grip the sides of the hole by one or more spuds 3 of axially short frusto-conical form, the load being applied to a central tension rod 4 provided with an end plate at the inner end of the plug. A favoured method (Figure 8) involves withdrawing the expanding spud 3 by means of a hydraulic jack, a removeable tube between the jack and near end of the plug accepting the reaction force. The tension rod is screwed into the end plate. The spuds 3 may be force inwards in succession by percussive blows on the tubular drift 5. Alternatively, the spud 3 may be forced in by the spigotal end of a cylindrical drift (Figure 6) which is then removed so that a tension rod can be screwed into the end plate. The spud 3 may be integral with the drift (Figure 7) which also serves as the tension rod. The anchorage will be capable of taking a load of up to 10 tonnes when placed in a 40 millimetre drilling as used for blasting operations. <IMAGE>
