Title: Method and apparatus for opening folded sheets
Inventor: SCHLOUGH JAMES R
IPC: B65H5/30
Filed: 1982-10-20
Abstract: A method and apparatus for opening folded sheets 15 which are being moved, for example from a stack by a forwarding belt 21. The belt directs the folded sheets to a guide 38 which causes one sheet flap 37 to be directed to one side of conveyor 27, and the other flap to pass over the other side of the conveyor. A mechanical or suction sheet opener can also be used for directing the other flap of the folded sheet to the far side of the conveyor which is running at an acute angle with respect to the direction of movement of the unfolded sheet as it approaches the conveyor. The opening of folder sheets is particularly useful when the conveyor is a gatherer collecting sheets from a plurality of stacks, e.g. when collecting for book or magazine production. <IMAGE>

Title: Recovery of zinc from sulphidic material
Inventor: WEIR DONALD ROBERT
IPC: C22B19/20
Filed: 1983-02-23
Abstract: A process for recovering zinc from zinc containing sulphidic material which also contains iron together with lead and/or silver includes leaching the material under oxidizing conditions in excess aqueous sulphuric acid solution to produce an undissolved residue containing a major proportion of lead and/or silver and a leach solution (A) containing a major proportion of the zinc and iron. The leach solution (A) is treated to recover zinc by feeding the solution to another process in which zinc- containing material is treated to recover zinc and which includes an iron-precipitation step. The other process includes roasting zinc and iron containing sulphidic material to produce a zinc oxide and zinc ferrite containing material, which is then leached in a weak aqueous sulphuric acid solution to dissolve zinc oxide and produce a leach solution containing dissolved zinc and a zinc ferrite containing residue. Zinc is recovered from a leach solution, and the zinc ferrite containing residue is leached in a strong aqueous sulphuric acid solution comprising at least a portion of the leach solution (A) containing a major proportion of zinc and iron. The leach solution containing dissolved zinc and iron is separated from the residue. Ferric iron in the leach solution is reduced to ferrous iron, and the ferrous iron is neutralized and hydrolyzed under oxidizing conditions to precipitate an iron compound, and the iron compound is separated from the remaining solution.

Title: Electrosurgical generator
Inventor: DAGUILLON CLAUDE
IPC: A61B18/12
Filed: 1983-11-03
Abstract: The generator comprises a clock (3) which supplies logic signals, at the frequency of 56 MHz, to counters (20- 21) having a programmable capacity, triggered off at each period of a fundamental frequency of 875 KHz obtained by division (at 40-41) of the clock frequency. Binary programming words for the counter are provided, from a microprocessor, by FIFO registers (10-11) adapted to periodically recycle the modulation sequence.

Patent GB-2156185-A (GB)
Title: Loudspeaking telephone instrument
Inventor: PHILLIPS IAN
IPC: H04M1/60
Filed: 1984-03-21
Abstract: A loudspeaking telephone includes first and second comb filters (2, 4) one in the receive path and the other in the transmit path and a control arrangement (11) which controls the pass and stop bands of the comb filters (2, 4). The comb filters (2, 4) have interlaced characteristics, i.e. the stopbands of one lie in the passbands of the other and vice versa. Thus signals passing through the comb filter (2) will be rejected by the comb filter (4) thus preventing their being emitted by the loudspeaker (3) and being coupled back to the microphone (1). The pass and stop bands of the comb filters (2, 4) are interchangeable in dependence on whether the loudspeaking telephone instrument is being used by the called or calling party. The control arrangement (11) detects which party is using the instrument and either interchanges the positions of the comb filters (2, 4) by means of switching (Figure 1) or modifies the characteristics of the individual comb filters (2, 4) by switching their internal circuitry (Figure 2). <IMAGE>

Title: Improvements in or relating to bulk material transposing vehicles
Inventor: GRIFFITH JOHN B
IPC: B60P1/36
Filed: 1984-05-23
Abstract: A bulk material transposing vehicle is described. The vehicle has a scoop 19 at its front end which, as the vehicle is driven along the ground, picks up the bulk material.
