Patent GB-2266587-A (GB)
Title: Dust containment device
Inventor: LETTICE ANDREW
IPC: B65G69/18
Filed: 1992-05-01
Abstract: A dust containment device is for a passage to a container or hopper for particulate material, and includes at least one restrictor along the passage. The or each restrictor comprises a support frame 8 and a baffle including a pair of baffle plates 10, each pivotally mounted along one edge to the support frame. The baffle plates are linked to a common counterbalance 16 such that in a closed state, the baffle has an inverted V-shaped cross-section and substantially prevents egress of material from the container via the openings. Loading of the baffle with particulate material in excess of a predetermined amount causes it to move to an open state in which the baffle plates pivot together whereby the baffle permits ingress of material to the container via the opening. The weights 22 on the counterbalance can be changed to modify the load at which the plates open. The edges of adjacent plates may not quite meet when closed to allow fine coatings or individual particles to trickle through. A passage may have a series of baffles some of which may be locked closed or open as required. There may also be steps to control the degree of closing of the baffles. <IMAGE>

Title: Preventing oil supply to screw compressor on shutdown
Inventor: ROACH JEROME C
IPC: F04C18/16
Filed: 1993-03-05
Abstract: A valve 56 is disposed internal of a refrigeration system screw compressor 12 which, upon compressor shutdown, shuts off the flow of oil injected into the compressor's working chamber 24 and the oil which is directed to the compressor rotor bearings 30, 32 and which at compressor startup opens oil flow to those locations by the use of ambient internal compressor conditions that exist at those respective times. The operation of the apparatus is therefore "fail safe" and the need for external oil flow cutoff valving and the need to monitor oil flow within the compressor is eliminated. <IMAGE>

Patent GB-2281828-A (GB)
Title: Analogue-to-digital converters and digital modulators
Inventor: THURSTON ANDREW MARK
IPC: H03M3/02
Filed: 1993-09-14
Abstract: In a conventional sigma-delta converter/modulator, quantisation noise of the quantiser 1 which produces the digital output is suppressed because of feedback loop 2 which feeds an error signal via a filter 4 to the quantiser, the error signal being the difference between the digital output and the input. Improved noise suppression is achieved by more filter stages, but such a converter/modulator requires special means to reset it in the event of an overload i.e. a high input signal. In the invention a modified output is taken from the filter 4 which is such that a second filter 6 appears, when the main loop is not overloaded, to be in a loop with a simple delay, i.e. a sigma-delta circuit. The main loop has the inherent recovery properties of a second order modulator/converter and cannot be swamped by the signal from the second loop because of a limiter 7 and, when the main loop has recovered, so does the second loop containing the second filter 6. However the quantisation noise is now suppressed by the combined filters 4 and 6. In an analogue equivalent the limiter 7 receives a signal representative of each of those filter orders to permit an equivalent impulse response to be provided. <IMAGE>
