Abstract: 1,060,098. Electrostatic copier. NUCLEAR CORPORATION OF AMERICA. Oct. 27, 1964 [Oct. 30, 1963], No. 43836/64. Heading G2H. An electrostatic copier comprises a tray for copy sheets 44 which are coated with a photoconductive material and which are removed by a conveyer 54 to pass between two rollers 46, 48 and between spaced wires 68 and 70 to which a potential is applied. The copy sheets then passes over an open window 84, where it receives the projected image of the original, and is carried between two contiguous belt conveyers 104, 72 to a developer system 106 comprising a tank containing liquid carrying particles to be picked up by the charged portions of the copy sheet. The open window 84 is bridged by strands of a filament divergent in the direction of movement of the sheet. From the developer system the sheet passes through a fixing system, in which heated air is blown on to the paper, and then on to the delivery tray 28. An original is fed into the machine through slot 142 between rollers 146 and 148 and operates a microswitch 156 to initiate movement of the copy sheet. The original passes a window 170 whereby an image of the original is projected on to a copy sheet through window 84 by means of a lamp 236, a lens 246, and reflectors. The original is guided to a gating device 180 which can be set to recirculate the original if more than one copy is required or else to return the original to a delivery tray 20.

Title: Method of developing latent fingerprints and apparatus therefor
Filed: 1961-12-21
Abstract: 969,245. Printing processes; detecting fingerprints. H. L. MACDONNEL. Dec. 21, 1961 [Dec. 29, 1960], No. 45920/61. Heading B6C. [Also in Division H1] A method of developing a latent fingerprint on a surface comprises applying a magnetizable powder to the surface and then using a magnet to remove the powder from that portion of the surface which is free of the oils defining the print. The powder, which may be of iron, cobalt or nickel or a mixture thereof, and which, furthermore, may incorporate a quantity of magnetizable filings, may be applied by brushing a cluster thereof on a magnet across the surface, the powder only adhering to the oil bearing portions of the print. A suitable magnetic device comprises a plastic, glass or aluminium body 20 having one end 22 closed and containing a magnet 24 which is slidable therealong by a rod 26. After use the powder is removed from the device by withdrawal of the magnet 24 from the closed end 22, a collar 28 on the outer surface of the body preventing corresponding movement of the powder. In an alternative device both ends of the body are closed, the magnet being slidably moved by a rod shaped to move in a longitudinal slot in the body. In an alternative method the powder may be applied to the surface in a layer which covers the whole print. The magnet is then passed over the print to remove the powder from the oil-free areas.

Abstract: 1,213,208. Automatic temperature control systems. HOLZER-PATENT A.G.Oct.2, 1968 [Oct.14, 1967], No.46816/68. Heading G3R. A heating element particularly for a hot plate has a temperature sensor in a bridge circuit having an output which is applied alternatively with a signal substantially dependent on power consumption through an OR gate 3,4 to an amplifier which operates as an on/off switching device controlling element current. A pot-bottom sensor 1 and a variable resistor 2 form with a rectifier 30, a bridge circuit one point of which is connected through a diode 3 to the base of an N-P-N transistor 7 coupled through a resistor 10 to another transistor 13, this being joined by a feedback device 9 to the base transistor 7. The device 9 provides a trigger characteristic. Transistor 13 controls through a triac 15 the current through a heater element 14. The triac 15 is also connected through diodes 16, 18 to transistors 13,7 this arrangement ensuring that the triac 15 commences conduction at voltage zeros. A series resistor 20 applies a voltage through a diode 23 to a Miller integrator 26 the output of which appears across a resistor 29 the magnitude of which provides a measure of the mean current flowing in the heater element 14. A tapping on resistor 29 is applied selectively through a diode 4 to transistor 7. Resistors 2, 29 should preferably be mounted on a common operating spindle and provide a stepwise adjustment. In certain positions of the spindle the tapping is disconnected. The triac is controlled by the pot bottom sensor below the set temperature and by the power circuit around this temperature. In another arrangement Fig. 3 (not shown) the Miller integrator is replaced by an R. C. circuit which is tapped from the junction between the triac and heater 14 but this arrangement gives the circuit a square law characteristic. This is compensated by another arrangement Fig.4 (not shown) which employs an additional R. C. circuit (51) the outputs of the two circuits being applied to resistors (21, 22) in series which provides mains voltage compensation.
