Title: Improvements in or relating to sheet collating machines
IPC: B65H39/105
Filed: 1954-05-13
Abstract: 752,201. Photo-electric control system. FORNELL, D. E., and FORNELL, B. S. May 13, 1954 [July 15, 1953], No. 14060/54. Class 40 (3). [Also in Group XVI] In a machine for collating sheets to form booklets (see Group XVI), unprinted sheets, fed from rollers 230 to a receiving bin 29, are detected by a photo-electric device 320 and diverted into a shoot 344. The device 320 is suspended from a bar 321 and divided into two compartments 324 and 325 containing a light bulb 330 a a photo-electric cell 331 respectively. The bottom of the case 330 is provided with a slot 329 heading from the case 320 is an electric cable 332 (Fig. 32) connected to a source of power through a switch 333 operated by a cam 336 on a shaft 108. A second cam-operated switch 337 is provided which when closed energizes a trip gate relay controlling a solenoid to open trip gate 295. In operation, as a sheet passes under the case 320 the cam 336 closes switch 332 to energize the photo-electric cell 331 and light source 330. The circuit is such that the intensity of light reflected from a blank sheet establishes the quiescent condition of the circuit. If, however, the sheet has printed matter thereon the quiescent condition is upset. Further rotation of the cam 336 closes the switch 337 to energize the trip gate relay which, if the quiescent condition of the photo-electric circuit is maintained by a blank sheet, operates the trip gate 295 to divert the sheet into shoot 344. If there is printed matter on the sheet the photo-electric circuit prevents the trip gate relay from operating the trip gate 295. Above the roller 235 a second photo-electric cell 350 is mounted which co-operates with a bulb 355 and serves to count the products delivered to a rotatable bar 29, and to control the-drive mechanism.

Title: Improvements relating to magnetic switching matrices
Inventor: WEBLEY REGINALD SIDNEY
IPC: H03K17/81
Filed: 1960-04-26
Abstract: 980,806. Magnetic switching matrices. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 26, 1961 [April 26, 1960], No. 14518/60. Heading H3B. The cores of a magnetic switching matrix each have three or four associated selection conductors which are coupled with groups of cores in such manner that no two conductors associated with any one core are common to any other core. In an arrangement using four selection conductors for each core, one conductor is continuously biased by a current producing a field of - 4À5 h, where h is the coercive force of the cores. To switch a desired core all four associated conductors are coincidently pulsed by driving currents each corresponding to + 1À5 h. At the termination of the pulses the core is reverted to its initial state by the bias. The high degree of bias and the wiring arrangement is stated to reduce the spurious outputs from unselected cores. The matrix is shown in Fig. 2, and each core P is coupled with a row conductor 1, column conductor 2 and diagonal conductors 3 and 4. The diagonal conductors are selectively connected in series to serve groups of cores, thus for one diagonal series pairs are formed by linking the ends of conductors 4a and 4f, 4b and 4g, 4c and 4h, and 4d and 4i, only one link being shown in broken lines. Conventional cores or thin films may be used. In modifications a separate bias conductor may be used, and only three selection conductors may be provided for each core.

[Classes 72 and 82 (i).] A method of reducing metals, particularly iron and copper, from their oxides comprises mixing the oxide-containing material and a gas in such proportions that the mixture has the properties of a viscous fluid, and passing the mixture in the presence of carbonaceous material through a heated zone for the reduction. In one form of apparatus for conducting the process a mixture of oxides and carbonaceous material is fed by gravity from a bin 1 into a barrel 3 having a propelling screw 4, and then enters a pipe 7 into which also the gas, which is preferably carbon monoxide or the gas from a previous reduction, enters from a ring 8 which is in connection with a gas reservoir. Perforations 13 in the pipe 7 communicate with the ring 8. The viscous column of gas and material under pressure from the propeller 4 passes through a continuation pipe 18 enclosed in a furnace 14, where the reduction takes place. The products are discharged into a settling chamber 20, the gas passing to a main 22 while the solids are cooled by a water jacket 24, and removed by a screw 25. A float 27 controls the discharge of the solids. In operation the chamber 20 is initially half filled with previously treated material, all air is excluded from the system and replaced by gas, and the entire system is heated to reduction temperature. Gas is turned on by a valve 12 and the material in bin 1 is fed by the screw 4.
