Title: Apparatus for handling rectangular documents
IPC: G06K13/07
Filed: 1975-12-04
Abstract: 1490609 Card reading system COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE CII - HONEYWELL BULL 4 Dec 1975 [11 Dec 1974] 49893/75 Heading G4M Document handling system, e.g. for use in banks, has a reading station and two stations arranged one on either side of the reading stations supplying documents to and receiving documents from the reading station. A conveyer mechanism transports the documents between the two stations. The reading station is adapted to read information from the document only when the document moves in a predetermined direction. The system has two document supply and removal stations A, B connected by a conveyer belt 19 driven by roller 20. Pressure rollers preventing the document from slipping are mounted on a hinged carrier 27 movable to allow the document to be entered and moved into or from the system. The system has a read head 11 and a plurality of optical position sensors PHA, PHB, PH1, PHL. The system may contain a document marker such as a printer 13 or a punch. As described characters printed in magnetic ink are magnetized by member 18, for sensing by the read head. In use an operator at either station A or station B inserts a document and activates a press button on a respective keyboard which causes an indicator to be lit indicating which operator is using the system and which prevents the other operator from using the system. The operator can either read or record of and check the document. If a read button on the keyboard is pressed, member 18 is activated and an electromagnetic clutch is operated causing the document to be advanced into the reader. The document passes through the reader and when the trailing end of the document is detected by sensor PHL the clutch is released to stop the drive. Member 18 is deactivated and a further electromagnetic clutch is operated causing the document to be returned to station A. When its trailing edge is detected by sensor PHI the drive is stopped and both stations are opened. If a document is to be recorded a different button on the keyboard is pressed and the indicator showing which operator is working lights and prevents access by the other operator. The document is inserted and its position sensed and if required the document is moved until its forward edge is clear of detector PHI. The document is then moved step by step towards station B until it has moved to a recording, e.g. printing position. Data is printed as the document is moved step by step through the recorder. After printing the document is moved either forwards or backwards until its leading edge is just before the reader. The recorded data is then read to check for errors and the document returned to the operator. If the document is entered at station B it is passed through the reader and recorder towards station A before the reading or recording operations commence. Details of the control circuits are given.

Abstract: 1,215,721. Automatic arc furnace control. ALLEGHENY LUDLUM STEEL CORP. Nov.17, 1967, No.52526/67. Heading G3R. A polyphase arc furnace has its electrodes positioned by a circuit responsive to the time averaged value of arc power. Each electrode e.g. 16 has signals proportional to arc voltage and current passed to units 80, 38. For constant power a signal proportional to power applied across a resistor 84 is compared with that across a reference potentiometer 94, the error being passed to units BSI, BSR, which adjust the electrode position through a servomotor system. By a switch (128) Fig.4 (not shown) the electrode spacing may be alternatively controlled by power factor through units BSHPF, BSLPF which similarly adjust the electrodes. The circuit may be arranged under power control when the power factor is within a range of values or power factor control outside this range. Potentiometers 104, 106 provide opposing currents to provide band width control and electrode power loss compensation respectively. The circuit may be controlled by any known programme arrangement, which may be coupled to controls 94 (128). In Fig. 1 (not shown) a signal proportional to power is compared through an averaging circuit (42) with a signal proportional to current so that electrode may be moved in an appropriate direction. A circuit comparing power change relative to current change may alternatively be employed. The power factor is separately controlled by adjusting the taps, off load, on a transformer feeding the furnace. The taps may also be adjusted if the range of circuit adjustment does not produce the desired power consumption. A low arc voltage short circuit detector 74 is provided which retracts the electrodes.

D.C. pulses or A.C. pulses of different frequency for each path/lead may be used. A serial binary train for transmission is contained in register REGT (Fig. 1) whose output stages are connected to bi-stables TA1 to TAN and via inverters I1 to IN to bi-stables TB1 to TBN. A ready signal TRMT opens gate G1 to allow pulses from generator PG to generate successive clock pulses on parallel leads OP1 to OPN which pulse in turn each register stager's pair of bi-stables-the stager being reset upon the termination of the corresponding PG pulse. According to whether a register stage contained a binary 1 or 0, one or the other of the bi-stables of each pair supplies a pulse to gate GA or GB. Transistor TRA1 or TRB1 accordingly switches off sending binary l's as negative pulses over line a and binary 0's as negative pulses over line b which are received in a receiver RCR by complementary pairs of transistors TRA2, TRA3 and TRB2, TRB3 connected to a common resistor RTP. A register SREG receives only the amplified output of pair TRB2, TRB3 over line DTA since the lines a and b are complementary, but is clocked by the output of both pairs combined in OR-gate GR.
