Title: Electrophotographic reproduction
IPC: G03G17/02
Filed: 1964-04-08
Abstract: 1,068,622. Electrophotography employing electrolytic development. KODAK Ltd. April 8, 1964 [April 8, 1963], No. 14459/64. Addition to 1,006,113. Heading G2H. A method of photographic reproduction comprises passing a direct current through an electrolyte in contact with the positive electrode and a photo-conductive layer which has been or is being exposed to a light image and is carried by a conducting layer connected as cathode, the electrolyte being a dilute aqueous solution containing ionizable magnesium and manganese compounds so that an imagewise deposit of the metal hydrioxides or hydrated oxides occurs on the photo-conductive layer n the exposed areas, and thereafter treating the deposited image with aqueous silver nitrate. The electrolyte also may comprise cobalt ions, or cobalt ions and/or cerium ions may be added to the silver nitrate solution. A blue dyed image may be obtained by incorporating a blue dye in the electrolyte so that dye is deposited together with the hydroxide image. Alternatively, the deposited image may be treated with a dye bath before treatment with silver nitrate or the dye may be incorporated into the silver nitrate bath. Ions of chromium, aluminium, bismuth, uranium or thorium also may be added to the electrolyte and the use of ferric ions is mentioned. In the examples, a layer of zinc oxide dispersed in an insulating binder, such as a styrene/butadiene copolymer and coated on an aluminium foil/paper laminate is exposed and simultaneously or subsequently developed electrolytically using an electrolyte comprising manganous, cobaltous and magnesium nitrates and with a potential of 20 or 30 volts between the aluminium backing and a stainless-steel frame acting as a developer retainer. The deposited image is swabbed with silver nitrate solution and the dried print may be lacquered with an acrylic ester resin. The silver nitrate solution may contain diethanolamine, and compounds such as 3-mercapto-1, 2,4- triazole, 2-thiobarbituric acid, 2-mercaptothiazoline, 5-mercapto- 1 -phenyl tetrazole, 5- methyl-oxazoline-2-thiol or 7, 13 dithianondecane- 1, 19-bis (pyridinium p-toluene sulphonate) may be included in the electrolyte. Reference has been directed by the Comptroller to Specification 963, 539.

Filed: 1921-05-31
Abstract: 179,837. Griffin, J. C. May 31, 1921. Sliding-jaw wrenches.-The sliding jaw of a wrench is provided with a toothed block which slides laterally in guides on the sliding jaw into and out of engagement with teeth on the shank of the fixed jaw so as to lock the sliding jaw, this block being moved into the locking position by spring-pressed blocks engaging inclined converging surfaces in the movable jaw. The sliding jaw 3 slides on the shank 2 which is toothed at 6. A toothed block 4 moves laterally in guides 5 on the sliding jaw and normally engages the teeth 6 to lock the jaw on the shank. Two blocks 8, 8<a> separated by a compressed spring 7, slide in the block 4, the outer ends moving on the converging surfaces 9. Side pressure on the block 4 causes it to move out of engagement with the shank, at the same time forcing the blocks 8 and 8<a> together and compressing the spring 7, the jaw 3 being then free to slide along the shank 2. On releasing the block 4, the spring 7 and blocks 8 and 8<a> force it back into the locking position.

An inductively heated cooking apparatus comprises a load inductor and capacitor connected in series across a thyristor 17 and diode 18 in back to back relationship, the inductor and capacitor forming a series resonant  inverter circuit 19 which is set into oscillation by the firing of the thyristor 17 and energized by way of an inductor L 2  and capacitor C 2  the load inductor being operatively associated with a metal base cooking pot whereby to induce current therein so as to cause heating of the articles in the pot. The inverter circuit 19 is supplied from an A.C. source 11, 12 by way of a main switch 13 and a full wave rectifier 14. Energization of the supply circuit is enabled by switching on a thyristor 21 which is controlled to become conductive at a zero point in the unsmoothed rectified A.C. by a zero point sensing circuit 22 which in turn is controlled by a start up delay inhibit circuit 23. The circuit 23 is itself controlled by means of a heating rate control circuit 25 which controls the level of the power supplied to the inverter circuit 19 and a temperature sensing circuit 24 which contains an infrared device sensitive to the heat generated in the cooking pot and sets, by way of a variable resistor 132 the maximum temperature to which the pot may be heated. Having enabled the power supply by switching on thyristor 21 a trigger pulse generator 33 is energized after a delay set by a variable resistor 34 to generate pulses which by way of a pulse amplifier 32 and transformer 31 gate the thyristor 17 whereby the inverter 19 becomes operative to cause heating of a cooking pot. Various refinements to the circuit are described whereby the capacitor in the inverter circuit 19 may be made variable to alter the output frequency of the inverter, to protect the circuit against heavy overload currents, additional smoothing inductor and capacitor components connected across the capacitor in the inverter circuit in which the smoothing inductor may form the induction heating coil, additional semi-conductor components to enhance the operation of thyristors 17, 21, an arrangement in which the diode 18 may be omitted, the rectifier 14 providing the function thereof and in which the heating apparatus may be other than cooking apparatus.
