Title: Circuit arrangements including an electric stepping motor
IPC: H02P8/12
Filed: 1971-09-13
Abstract: 1400995 Control of stepping motors SANGAMO WESTON Ltd 13 Sept 1972 [13 Sept 1971] 42584/71 Heading H2J [Also in Divisions G4 and H3-H5] An electric circuit supplying pulses of alternate polarity to the winding 10 of a stepping motor, comprises a battery 14, a capacitor C1 in series with winding 10, and two switch means. The first switch means conducts upon the arrival of an input pulse on line L, Fig. 3, or at an input T, R or E, Fig. 4; capacitor C1 charges up through a diode D1 and winding 10 and the rotor of the stepping motor rotates through 180 degrees. In the absence of an input pulse the second switch means conducts to discharge capacitor C1 through winding 10 thus rotating the rotor through a further 180 degrees. The rotor may operate the cyclometer register 12 of a pulse counter.  In the embodiment of Fig. 3, the first switch means comprises an NPN transistor T2, across the base and emitter electrodes of which are applied the filtered, rectified and smoothed input pulses, and a Zener diode. When an input pulse ceases T2 stops conducting and C1 discharges through the second switch means which comprises a transistor T1. In the embodiment of Fig. 4, the input pulses are fed to a resonant filter transformer TR, the resulting A.C. pulses being applied across the base and emitter of an NPN transistor T4 which constitutes the first switch means and which, with a PNP transistor T3, constitutes a trigger circuit. In this embodiment a pulse will be applied to winding 10 even if the duration of the input pulse to TR is shorter than the charging time of C1. A positive-going pulse from TR in excess of the threshold voltage of Zener diode ZD switches on T4 and C1 charges through a resistor R4. As the voltage drop across R4 rises T3 begins to conduct until C1 is charged up. In the absence of a signal from TR the trigger circuit ceases to conduct and C1 discharges as in the previous embodiment. The arrangements may be connected with a telephone line to monitor call charges.

Title: Machine for applying address labels from address list bands
IPC: B65C9/18
Filed: 1972-09-14
Abstract: 1403625 Labelling machines KONTTORIKONETEOLLISUUS OY 14 Sept 1972 [24 Sept 1971] 42634/72 Heading B8F [Also in Division B2] In an addressing machine, a web 1 having two or more rows of printed addresses is fed in steps corresponding to the length of the addresses by intermittently driven chains 4 having pins engaging perforations 56 in the edges 54 of the web. The perforated edges 54 are then severed by knives 5, and elements 6 perforate the web between the rows of addresses. When a transverse strip 60 of addresses arrives on a table 10 it is severed from the web by a knife 9. The label strip 60 is then fed transversely of the web direction by a driven roller 11 co-operating with a counter roller 13 until the leading edge of the leading label enters the nip between an applicator shoe 14 and a roller 15, whereupon the counter-roller 13 is raised by a cam-and-lever arrangement 32, 47-53 and a brake 16 momentarily applied to the next label. The leading label is thus torn from the strip and is carried by the shoe 14 past a gumming roll 17 and applied to an envelope on a feed track 59. The counterroller 13 is then lowered and the label strip is fed another step to apply the next label. Contacts 18 associated with the brake 16 close when the last label has been fed and the feed chain 4 is then driven for a further increment. The feed chain is driven through a ratchet drive arrangement having two sets of pawls selectively operative to give two feed distances for the web to accommodate addresses of two lengths. Should an envelope be missing, this is detected by a photo-cell and energizes a solenoid 20 which maintains the counter-roller 13 raised to withhold a label.

A door closer comprises a piston 11 in an hydraulic cylinder 10, moving on opening a door against the action of the spring 12 and the working fluid being displaced through the non-return valve 16; on release of the door, spring 12 tends to reverse the motion of the piston 11 and cause the door to close, the working fluid returning to the other side of the piston by two restriction valves 17, 18 and the associated flow tube 29. The restriction valve 17 controls the speed of flow of fluid through the passages 27, 24, 28 and operates throughout the movement of the piston. The second restriction valve 18 operates over the last part of the closing movement to increase the speed and ensure closure or latching of the door, being brought into action by the piston moving the hollow plunger 30 with ports 34 in an external annular recess 33 (acting as an auxiliary valve) so that the ports 34 are open to the valve 18 through which the fluid passes to the chamber 24 and thence through the return tube 29 to the low pressure side of the piston. The safety valve 37 allows the door to be forcibly closed without subjecting the closer to unduly high pressures. The door is connected to the spindle 15 by a suitable link mechanism.

Abstract: 1,140,276. Current collectors. E.M.S. ELECTRICAL PRODUCTS Ltd. 19 Sept., 1967 [1 Oct., 1966], No. 43950/66. Heading H2E. In a current collector for supplying electrical apparatus on a mobile carrier from a bare overhead conductor, a swivellable shoe is supported at one end of an arm, the other end of which is pivotally connected to a rotatable hub through a resilient body of insulating material which, in use, biases the shoe against the conductor. As shown, a hub 113, pivotally mounted on a bracket 112 which is secured to a mobile carrier (not shown), is integral with a longitudinally split cylindrical housing 18. Two parallel arms 22, 23, are connected at one end by screws 30 to an assembly which includes a rubber annulus 24, the assembly being rotatable in the housing 18 about the axis of the screws 30, and lockable in a desired angular position therein by a clamping screw 20 which engages a tangential extension 19 on the housing 18 and a threaded hole in the hub 113. At their other ends arms 22, 23 are united by a clevis 39 which is pivotally connected to a vertical tube 38. A third arm 31, below and parallel to arms 22, 23, is pivotally connected near one end through resilient bushings to base lugs on housing 18, and near its other end to a bifurcated end of tube 38. A conductive shoe 60 having a grooved upper edge to receive an overhead conductor (not shown) is secured by washers 61 and bolts 63 in a generally troughshaped insulating moulding 49 which is secured in a U-section support bracket 46 by bolts 47 and nuts, the bolts passing through spacing bushings 48 in converging slots 54, 55 in moulding 49 to enable the latter to tilt to align shoe 60 in parallel with the conductor. Bracket 46 is swivellably mounted on a stub shaft 43 which is a force-fit in tube 38, and electrical connection is made to shoe 60 via a tab 64, an insulated conductor 66, and a connector 67 on the mobile carrier. In use, shoe 60 is upwardly biased against the overhead conductor by the rubber annulus 24. Excessive pivoting of the hub is restrained by the engagement of an end 78 of arm 31 in a bifurcation 77 in the upturned end 76 of a stop plate 74; and the other end 83 of arm 31 co-operates in a similar way with a stop plate 81 to restrain undue swivelling of support bracket 46.
