Abstract: 402,178. Supply and control systems for consuming - - devices; transformers. THOMAS, A., 3156, Yonge Street, Toronto, Canada. July 5, 1932, No. 18958. [Classes 38 (ii) and 38 (iv). Systems depending on static transformers.- A circuit controlling arrangement for electric signs comprises a plurality of secondary windings supplied from a primary winding or windings and electrical or mechanical means to reduce the magnetic flux from the primary to the secondary windings. In Fig. 2 four lamp sets 34<1>, 34<11>, 35<1>, 35<11> are supplied from the secondary windings 361 36<11>, 371 37<11> having U-shaped cores 39. Spaced from these windings is a primary winding 41 with core 42. Between the two sets of windings move a pair of members 45 of conducting material, each member consisting of two bars 45<1>, 45<11> joined by a cross bar of non-magnetic and non- conducting material 46 (see Fig. 3). A rod 47 joins the two members and is given a reciprocating motion by means of a pitman 48 driven from the motor 52, so that at any time, three of the secondaries are bridged to allow magnetic flux to flow to them and energize the lamp circuits. In Fig. 5, a similar flickering is attained by a rotating primary winding 53 with a core presenting three sets of poles 61 to three of the four secondary windings 54 associated with the lamp circuits 55. Current is supplied through slip rings on the axle which is rotated by a pulley. Figure 9 illustrates fixed primary and secondary coils 74, 80 respectively provided with U-shaped cores, and a rotary intermediate member 69 having three sets of lateral poles of conducting material. Revolution of the member 69 brings the poles into such position as to allow the transmission of magnetic flux to three of the secondary windings. Specification 370,310 is referred to.

Title: Document reject re-entry
IPC: G06F7/06
Filed: 1975-05-06
Abstract: 1488623 Document sorter RECOGNITION EQUIPMENT Inc 6 May 1975 [30 May 1974] 18971/75 Heading G4M A sorting machine for documents such as cheques has a facility for removing incorrectly read documents and correcting and replacing the documents. Cheques are moved along a path 50 past an MICR reader 57 and an OCR reader 62. The cheque carries an account number and an amount printed in MICR format. The account number identifying the bank and the cheque owner and the amount is read both optically and magnetically by the readers and the results are compared and merged 120 to reduce errors in reading. The merged data passes to a multiplexor 122 which also receives a Positive Item Control Number (PICN) which identifies the document and also its storage location on micro film. The data passes to a Control/Inhibit circuit 131 receiving a signal from a bar code reader 65 to prevent the operation of a bar code printer 70 and an alphanumeric printer 74. Reader 65 and multiplexer 122 also feed a computer 129 which records the data on tape 150. Circuit 131 in the absence of a bar code feeds printers 70, 74 via respective delay buffers 133, 134 to print a bar code equivalent on the data on the rear of the cheque and an alphanumeric equivalent on the front surface of the cheque. The printed bar code is read 72 and compared with the data 132. If the data is correct the cheque passes a sensor 24f and both sides of the cheque are microfilmed at a location determined by counters 24d, 24e which also feed PICN 125. The cheques are then sorted. If the data does not compare or if the data from multiplexer 122 is not verified 130 a reject multiplexer 141 causes the cheques to be sorted into a reject bin 144. The verifier 130 also prevents operation of the printers. Invalid cards are examined by an operator at a console 204 and data on the cheques is compared with data recorded on tape 150 and the data on the tape is converted. The cheques are passed through the readers and the computer controls printers 63, 74 to print corrected data. If a given number of consecutive incorrect cheques are detected 161, 163 the cheque feeder is stopped 164.

Abstract: 350,254. Valve amplifying circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. June 21, 1930, No. 18998. Convention date, July 5, 1929. [Class 40 (v).] The reaction of the anode load, constituted by the winding of an electromagnetic relay, on the control voltage of a thermionic detector is compensated by a voltage feedback from the anode to the grid circuit whereby the valve acts as if its impedance were high compared with the inductance of the relay winding. The relay winding 6, Fig. 1, is connected in the anode circuit of an anode bend detector 1, and carries a second winding 10 giving a reversed feedback to the grid circuit, the valve being biased so that the anode current is normally zero. Instead of the compensating coil being wound on the relay a transformer may be used with its primary in parallel with the relay (Figs. 2 and 3, not shown). Fig. 4 shows a grid detector with a relay and feedback coil as in Fig. 1, a variable resistance 16 and battery 17 being connected in parallel with the relay coil 6. The resistance and battery voltage are adjusted so that the voltage drop in the resistance is neutralized by the battery, the winding 6 being thus normally de-energized. Fig. 5 shows the application to a pair of detector valves fed in push-pull, the relay coil 6 and feedback coil 10 being arranged as in Fig. 1.
