Title: Inker cam drive system
IPC: B41F31/00
Filed: 1973-08-01
Abstract: 1427834 Drive control in printing machines HARRIS CORP 1 Aug 1973 [16 Aug 1972] 36661/73 Heading B6C [Also in Division G3] The individual motors driving the inking mechansim in a printing press are controlled by a control circuit which receives a signal representing the speed of the press and an error signal derived from sensing the relative travel of press and inker and produces an output signal to control that particular inker. The press has a main tachometer generator 50 producing a voltage signal proportional to speed and subsidiary pulse generators 44, 46, 48 each producing a pulse output at a different repetition rate. A selector switch allows the inker mechanism to be synchronized with any of the pulse outputs. The inker mechanism drive motor is connected to a pulse generator 38 which also produces a train of pulses. The train of pulses and the selected pulse output are supplied to gating arrangement 84 where their time of occurrence is compared by using the first pulse to open a window and the next pulse to close it to give a window pulse on terminal 86. An arrangement of bi-stables 90, 92 in gate 84 is also able to provide a logic signal on line 88 representative of which pulse arrived first and this signal is used to operate relay 146. A voltage to frequency converter 114 supplies pulses to counter 128 during the period the window is open and the frequency of these pulses is proportional to the square of printing press speed. The output of counter 128 is converted to an analogue signal and passes to a sample and hold circuit when a latch pulse is generated at the end of the window pulse. Relay contacts 146a, 146b apply a signal correctly poled to reduce the tracking error to amplifier 64 both directly and through integrator 154 where these signals are combined with the speed signal from tachometer 50. The inker motor 32 has its speed varied by controller 66 whereby the inker is maintained in the correct phase relationships to the printing press. The invention is particularly applicable to multi-colour presses where the printing units are driven together by the main drive but each inking train has its own drive motor.

Title: Improvements in or relating to semiconductor control devices
Inventor: GUNN JOHN BATTISCOMBE
IPC: H01L29/00
Filed: 1955-12-22
Abstract: 849,476. Semi-conductor pulse circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 5, 1956 [Dec. 22, 1955], No. 36841/55. Class 40(6). [Also in Group XXXVI] An electric control device comprises a semiconductor body having a first base electrode and a second non-injecting alloy junction electrode of area less than 0À001 in<SP>2</SP>, whereby under saturated drift velocity conditions, avalanche injection of carriers occurs to provide a negative resistance region in the forward characteristic. Fig. 3(a) shows an N-type germanium body 3 with a nickel plate base electrode 6 joined by a tin-antimony solder layer 7 which provides an N+ layer 5. A non-injecting alloy electrode is provided by a dot 8 of tinantimony which produces an N+ layer 4. Etching is used to reduce the size of dot 8 before alloying. The device has a negative resistance region in its "forward" characteristic, i.e. with a positive voltage applied to dot electrode 8. Both the "onset" voltage at which the current suddenly decreases with increasing voltage, and the "sustaining voltage" are reduced by previous avalanche experience, but these may be restored by etching treatment. Fig. 3(b) shows a modification in which a nickel sheet base electrode 6 which acts as a cooling element, is indium soldered to an intrinsic germanium body 3 to provide a P+ region 10, and a gold-antimony wire 11 is used to form a second non-injecting electrode with a gold-antimony-germanium region 12 and an N+ region 13. At the minimum, the spacing between layers 13 and 10 is 40 Á; this must be related to the impurity concentration of the intrinsic material by a given function, which involves electronic charge, dielectric constant, the avalanche field and the sustaining voltage. In operation, avalanche injection occurs at both electrode regions in this embodiment, and the arrangement avoids overheating at the non- injecting electrode. The base electrode may be provided by placing a fragment of indium and a droplet of zinc chloride on a nickel strip, and pressing an etched wafer of germanium against the indium and nickel while heating the nickel plate. A gold wire with 0À5% antimony is then alloyed to the surface of the germanium at a temperature of 330‹C. Reference is made to the provision of a third electrode for triggering purposes. Fig. 7 shows a pulse generator, in which a coaxial cable 14 fed with primary pulses from a hydrogen thyratron (not shown) is connected to an open circuited length of coaxial cable (Z 0  = 75 ohms) 17 through resistor 18. Each primary pulse charges cable 17 until avalanche diode 20 reaches its "onset" voltage when cable 17 discharges through 20 to provide an output across load resistor 21. The avalanche diode could also be used in oscillators or in "dissected" amplifiers, or in voltage stabilizing circuits. Specification 727,900 is referred to.

The timer comprises a motor controlling a cam-shaft which may be manually advanced by a knob (20). The cam-shaft controls contacts which ensure that for determined angular positions the power supply to the washing machine is cut off, the blower and timer motors and electric heaters are connected to the mains supply and the reversing switch is connected to the washing machine motor, while for all other angular positions the washing cycle operates. Air from outside is drawn into the casing 3 of the loading door 1 through vents 8 and then passes to centrifugal impeller 4 through a central aperture thereof. The air is blown radially outwards over clad-resistive elements 12 wound around the impeller 4 and passes through duets 9, 10, 11, into the tank of the washing machine containing the rotating basket or drum. The temperature of the air is controlled by thermostats (13) in the duct 9. The impeller is driven from a motor 5 which has a small cooling fan 15. In an alternative embodiment the circular clad-resistive elements are replaced by bare wire elements (12) in the duct (9), Fig. 5, not shown. In this case a valve (16) is situated to close the duct (10) to protect the elements when the washing machine is in its washing cycle. The timer knob may incorporate a switch for disconnecting part of the electric heaters thus providing two heating rates.
