Abstract: 945,019. Electric selective signalling systems. SIEMENS & HALSKE A. G. Feb. 15, 1962 [Feb. 15, 1961], No. 5826/62. Drawings to Specification. Heading G4H. In a mail sorting office an operator keys an address read from an envelope into a machine which then deposits a corresponding pattern of magnetic marks on the envelope to control its subsequent mechanical sorting into the bag of the postman who delivers to that address. Each road in the region served by the sorting office has an associated group of four letters known to the operator (for example the letters for Hedwig Street are 'HDWG') and the operator keys these successively whereupon a corresponding set of four cores in a core matrix are set. These cores are then read-out simultaneously and the output windings are so connected to a second core matrix, every core of which receives a bias of -3 units, that only one core of the second matrix is set. This second matrix is then read out and the output windings thereof, of which there are two per core, are so arranged in two groups of ten as to provide a decimal output. This decimal output is further recoded, by a third matrix, to a twoout-of five code to control the magnetic printer. Should the road by itself be insufficient information to result in a unique allotment (as for example when two postmen serve different parts of one road) an indication to this effect is produced by the second core matrix whereupon the operator keys the number of the house in the road. While this is being done the road is stored in the third core matrix. When the house number has been registered in the first register, both it, and the road from the third matrix, are read into a fourth matrix which, in turn, controls the printer.

IPC: G01C19/26
Filed: 1955-03-03
Abstract: 785,126. Gyroscopic apparatus. SMITH & SONS (ENGLAND), Ltd., S. March 1, 1956 [March 3, 1955], No. 6375/55. Class 97(3) A gyroscopic caging device consists in a first cam on the inner gimbal ring having an operative contour lying in a plane passing through the outer gimbal axis normal to the inner gimbal axis and formed with an inwardly-directed depression, a first plunger movable along the outer gimbal axis to co-act with the first cam and to engage a depression therein when the inner gimbal has been caged, and means to cage the outer gimbal ring about the outer gimbal axis. As shown, the rotor casing 2 is pivoted in bearings 3 in an outer gimbal 4, which is mounted in bearings 6 in plates 7, 8 fixed in an outer casing. Stops 12. on the inner and outer gimbals limit their relative rotation to an arc of about 45 degrees. The rotor casing 1 carries a cam plate 13, which has two curved portions each. having the form of an equangular spiral, meeting in a notch 13a. A plunger 14 may slide through the bearing 6 to press against the cam 13, which is thereby turned until the plunger is located in the notch 13a, in which position the rotor casing 2 is caged. The curved profile of the cam 13 may be made circular, without departing too far from the ideal equangular spiral form. A second channel form cam 15, attached to the outer gimbal ring 5 and lying outside the bearing 6. consists of opposite-handed helices centred on the outer gimbal axis and having a depression between them. Cam 15 is engageable by a plunger 16 movable parallel to the plunger 14. Both plungers are located by guide holes in plates 7, and are mounted on a carrier 17 positioned by the plunger 18 of a solenoid 19. Plunger 16 is connected by a spring 14a to the carrier, but plunger 16 is connected directly to the carrier. When the 'solenoid 19 is not energized, the plunger 18, and therefore the plungers 14,. 16, are retracted by means of a spring 18a. Energization of the solenoid 19 causes the plunger 18 to advance, moving the plungers 14, 16 into contact with their respective cams until the gyroscope is caged. Just before the plungers reach their final closing position an insulated projection 17a on carrier 17 closes contacts 21 to operate an indicating device.
