Patent GB-2009716-A (GB)
Title: Improved pick-off device for electrostatic copier
IPC: B65H29/56
Filed: 1978-11-22
Abstract: An improved pick-off device for a copying machine of the xerographic type in which a blade having a transversely tapered end and releasably secured to a resiliently restrained element of a clutch assembly is resiliently biased into engagement with the photoconductive surface to strip the leading edge of a sheet to which an image has been transferred and guide the sheet into a narrow space between said element and a continuously driven clutch element. Entry of the sheet into said space frictionally couples the two clutch elements to cause the restrained element to move with the driven element against the action of the restraining means to carry the sheet away from the photoconductive surface. After a predetermined rotation of the clutch elements, as the sheet enters the nip between upper and lower delivery rollers, the sheet is released from the clutch members and the blade restored to its initial position.

Patent GB-2039229-A (GB)
Title: Method and apparatus for concentrating trace materials from water
IPC: C22B60/02
Filed: 1979-12-18
Abstract: For the concentration of materials such as uranium, present in trace quantities in water, especially sea water, carrier bodies able to take up the material from the water are released into it so that their density causes them to sink downwardly or float upwardly to a collection region from whence they are transferred to a chemical plant for removing the trace material concentrated on them. The bodies can then be recycled for release once again from the original discharge point. To avoid abrasion of material providing sites for the uptake of the trace material to be concentrated, this material can be located on surfaces set inwardly from the periphery of the carrier bodies. A ring shape for the carrier bodies gives advantageous flow of water around the bodies. <IMAGE>

Title: Improvements in or relating to dc converters
IPC: H02M1/34
Filed: 1980-07-22
Abstract: A d.c. converter produces a d.c. output voltage from a lower d.c. input voltage by chopping the input voltage with a switch. A snubbing capacitor 7 is connected across the switch to prevent damage to the switch when it changes from a conductive state to a nonconductive state.
