Title: Improvements in or relating to electromagnetic relays
Inventor: YULE WILLIAM HENRY DRURY
IPC: H01H51/20
Filed: 1955-08-10
Abstract: 809,432. Electromagnetic relays. STANDARD TELEPHONES & CABLES Ltd. Aug. 10, 1955, No. 23011/55. Class 38 (5). A relay comprises a pair of parallel cores 1, 2, one or both of which carry one or more windings (not shown), and connected by magnetic bars 3 situated centrally as shown or at one end of the cores. A pair of armatures 4, 5 hinged at the ends of the core 1 have cross-plates 6, 7 connected by bars 8, 9 operating contact spring sets 10, 11. In one method of operation the bars 3 are central and a winding is placed on each end of the core 2, energization of one or the other winding causing attraction of a corresponding armature. Thus, there must be always one winding energized. In another method of operation, the bars 3 comprise permanent magnets and are situated at one end of the cores and only a single winding on core 2 is necessary. On de-energization of the winding the attracted armature remains held by the permanent magnet flux. The polarity of the energizing current determines which armature is operated. In a further arrangement permanent magnet bars 3 having soft iron shunts are placed at one end of the cores 1, 2, the armature nearer to the bars 3 (e.g. armature 5) having a much greater reluctance than the armature 4 and being spring-biased to the released position. When the coil is not energized the armature 4 is held in the attracted position by the spring. Current in the coil of one polarity serves to reinforce the spring pressure whilst current of the opposite polarity causes attraction of the armature 5. An actual relay construction is described with reference to Figs. 2-6 (not shown), this construction being similar in a number of respects with the relay disclosed in Specification 809,431.

Filed: 1971-04-19
Abstract: 1,273,953. Ticket handling. INTERNATIONAL BUSINESS MACHINES CORP. 19 April, 1971 [31 March, 1970], No. 23054/71. Addition to 1,165,140. Headings G4M and G4T. In apparatus for marking sheets (e.g. tickets for use in a public transport system) on one predetermined surface, a sensor detects the orientation of a presented sheet and activates a device to turn the sheet over if the orientation of the sheet is found to be unsuitable for marking the predetermined surface. The apparatus shown is for handling tickets of the type disclosed in the parent Specification, which tickets have spaces for recording printed information on one side and a magnetic stripe for recording further information on the same side. Such a ticket, presented at 11, is fed by a drum 20 past a read head 50. If the magnetic stripe faces the drum, head 50 is unable to sense the magnetic data and the ticket is caused to traverse circular path 18 a second time. If its second read attempt fails, head 50 generates a signal which pivots a gate G2 to divert the ticket from the drum, over a roller 120 and into a throat 34 between two pivoted arms. The arms then pivot clockwise to the position shown and a spring 130 pushes the ticket under roller 120 and back to drum 20. As the ticket traverses path 18 for the third time, and providing it is not found to be wanting in one of the ways indicated below, the magnetically recorded information value of pre-paid fare units is read at 50 and up-dated at 60, the ticket then passing between rollers 120 and 74 to be carried by an endless belt 70 to station 280, where its printed information is up-dated, and returned to the passenger at 48. If head 50 senses that the magnetic data corresponds to a remaining value, but that there is no space left for up-dating this data, the ticket is fed from drum 20 and by belt 70 to a gate G10, which holds the ticket beneath the exit slot. A new ticket from a hopper 260 is encoded at 60, checked at 50 printed at 280 and delivered to the passenger at 48. Meanwhile, gate G10 has been pivoted to allow the old ticket back on to drum 20, from whence it passes via gates G2 and G4 to a hopper 270, where it is retained. If the magnetic data corresponds exactly to the value of the ride taken, the ticket is retained at 270 and the passenger gate opened. If head 50 senses a remaining value less than that of the ride taken, the ticket is returned to the passenger and a display (not shown) is activated instructing the passenger to insert his ticket in a further unit (not shown). The further unit reads the ticket and informs the passenger of how much extra money he is required to insert to regain his ticket in up-dated form.
