Title: Improvements in ink adjusting mechanism
IPC: B41F31/04
Filed: 1962-12-18
Abstract: 961,766. Inking-apparatus. WOOD NEWSPAPER MACHINERY CORPORATION. Dec. 18, 1962 [Jan. 16, 1962], No. 47761/62. Heading B6C. A printing press of the type having a flexible blade 12 extending along the length of a fountain roll 11 and controlling the amount of ink thereon is provided with a mechanism for flexing the blade at specified portions comprising a reversible endless belt 17 driven from a motor 19, a plurality of rotatable screw means 20 positioned along the length of the blade to vary the flexure thereof, and a selectively controlled clutch means 14 for operatively connecting each screw 20 with the driven belt 17, each clutch 14 having a gear 40 in continuous meshing engagement with the belt 17 and a gear 43 adapted to intermittently mesh with a gear 30 on the screw 20 to selectively flex a portion of the blade. The gear 43 is mounted on a pivoted shaft 41 and is normally held out of engagement with the gear 30 by a spring 47. Energization of a solenoid 51 of a clutch unit 14 moves a bar 52 to the right and causes the shaft 41 to pivot against the action of the spring 47 and the gear 43 engages the gear 30. An end 32 of each screw 20 engages a lever 33 which has a cam surface 34 engaging the blade 32. A handle 20<SP>1</SP> is provided for manual adjustment. An adjustable stop 37 limits movement of a plunger 35 and thus the lever 33 so that the blade cannot contact the roll. When the plunger 35 contacts the stop 37 axial movement of the screw 20 stops and reaction between the gears 43 and 30 and the force of the spring 47 overcome a spring 54 so that gears 43 and 30 are disengaged even if the solenoid is still energized. A limit switch is actuated by grooves in a disc supporting the belt 17 to operate an indicator light on a control panel, Fig. 5 (not shown). An operator at the remote control station, which may control more than one press, controls the amount of ink delivered to a selected portion of a fountain roll by pressing one of the switches on the panel which actuates an individual solenoid. Other switches are provided to control the page-wide ink supply as opposed to the columnar supply. The operator determines the amount of ink controlled by counting the flashes of the indicator light which correspond to the movement of the belt 17.

Title: An Improved Bobbin Hanger
Inventor: KITAMURA SHINZO
IPC: D01H1/18
Filed: 1967-10-23
Abstract: 1,199,785. Bobbin support. S. KITAMURA. 23 Oct., 1967 [12 June, 1967], No. 48146/67. Heading D1J. A bobbin hanger, which can be caused to support a hollow bobbin by pushing the end of the bobbin upwards against collar 13 comprises a stem 2 supported on a member 3, the stem 2 carrying at its lower end a pair of pawls 23, 24. A cylindrical guide member 1 having slots 10 to accommodate the pawls is slidable on the stem 2 and a transverse pin 16 in the lower end of the guide member 1 is provided to engage the pawls 23, 24 and swing them outwardly when the stem 2 is inserted in the bore of the bobbin and the guide member 1 is moved upwardly relative to the stem 2. There are also means 28, 29, 30 to temporarily fix the guide member 1 relative to the stem 2 in a first position in which the pawls are swung outwardly and a second position in which the pawls are retracted. As shown, pivoted pawls 23, 24 are forced outwardly to engage with an internally stepped hollow bobbin when the latter is pushed upwards against the collar 13, Collar 13 is thereby lifted upwards and abuts broadened part 4, of cylindrical guide member so as to lift it. The pin 16, which extends horizontally through the lower end of guide member 4, thus forces the pawls 23, 24 apart to engage with the bobbin. The pawls 23, 24 are kept apart by a ball 30 and cam grooves 28 and 29 which prevent the guide member 1 returning to its initial lowest position (shown). The cams 23 and 24 can be moved inwards again by pushing the bobbin upwards so that the ball 30 and cam grooves 28 and 29 permit the guide member (together with its pin 16) to return to its lowest position. The guide member 1 is continually urged downwardly by spring 27. Alternatively, (a) pawls 23, 24 may be urged apart 'by a spring (not shown) (b) collar 13 can be omitted so that the bobbin presses directly against broad portion 4 of the guide member (see also Fig. 8 not shown) (c) guide member can move downwardly only under the action of its own weight. The cap 3 of the bobbin hanger is rotatably mounted on ball bearings 6 which are supported by a threaded screw 5. This screw, and the corresponding aperture in cap 3, may have flat circumferential portions, see Figs 5A and 5B, not shown. A wire brake supported on the cap may act on the bobbin support, see Fig 10, not shown.

Title: Improvements in or relating to telecommunications exchange switching networks
IPC: H04Q3/54
Filed: 1969-10-02
Abstract: 1,240,783. Automatic exchange systems. SIEMENS A.G. 2 Oct., 1969 [3 Oct., 1968; 24 Oct., 1968], No. 48381/69. Heading H4K. In order to hold connections over relay matrices the hold wires contain a series of holdwindings and associated hold contacts and the time required for marker action in establishing a connection is reduced by providing an auxiliary holding current path which allows the marker to retire before the hold circuit is fully established at a junction or switching stage interface. The invention is particularly applied to a folded network of the sort in which the number of stages required for a connection depends on the distance apart of the terminals being connected. As shown in Fig. 5, connections are held to battery over relays T and M in the terminal circuits at one edge of the network, release being possible from either end by virtue of contacts at, am. Stage relays KVA, KVB, KVC are separated by link state relays ZAB, ZAC. Completion of the hold circuits to earth depends upon the series of self-holding contacts operated by the marker and upon the junctor relays ZCCa and ZCCb. The marker may release without waiting for the relays ZCC because holding current will be drawn over diode G from auxiliary source E provided in common to a number of hold circuits. When ZCCa and ZCCb finally energize, diode G is back biased and holding current is given earth over series contacts zcca, zccb. The auxiliary source E may be connected over make/break contacts of the relays ZCC in place of using diode G, Fig. 4, not shown. The auxiliary source may comprise a switched transistor, Fig. 13, not shown. In order to connect hold wires in connections that involve fewer connection stages than the maximum, the hold wires are split, as shown in Fig. 10, the hold windings of the verticals of the switching stage matrices A, B and C, are served by one hold wire or the other of a pair for each vertical. Auxiliary hold current sources Ea, Eb, Ec are provided for each stage. If some terminals are always originating and others are always the subject of termination the split hold wires may serve corresponding crosspoints; otherwise the distribution of crosspoints to one hold wire and the other is varied from vertical to vertical. The hold wire circuits are passed on to a next stage by relays Ac, Bc, according to the split employed in a connection. In the C-stage, this being the last stage of the folded network, a relay CC enables the split hold wires to be combined as a single wire when a link is employed which extends a connection from one C-stage outlet to another.

Abstract: 1,241,357. Controlling reactors. NUCLEAR POWER GROUP Ltd. 3 Dec., 1970 [3 Oct., 1969], No. 48695/69. Heading G6C. An arrangement for progressively reducing the flow of gas coolant through a fuel channel in a reactor core to maintain constant outlet temperature of the coolant during the life of a fuel charge, comprises a valve body 1 of graphite or steel intended for location in the upper end of a fuel channel through which the coolant flows downwardly. The body 1 has an outer circular array of gas ports 2a and central gas ports 2b, these ports being initially open and being progressively closed by steel or graphite balls 9 introduced, singly, from an overhead hopper (Fig. 6, not shown) into the upper end of a curved guide tube 4. Thus, on leaving the tube 4 the first ball 9 probably comes to rest over the first port 2a, the top of the ball being flush with the ball track so that the next ball rolls over the first ball and stops over the second port 2a. After all the ports 2a have been blocked further balls cause blockage of the ports 2b. The pressure of the gas coolant seals each ball 9 against its respective port.

Abstract: 1,237,826. Controlling motor vehicles. FORD MOTOR CO. Ltd. 11 Oct., 1969, No. 50038/69. Heading B7H. [Also in Division E2] A motor vehicle has a transmission 4 which can be set in either a neutral or a driving condition by a driver-operable transmission control, a passenger door which can be put in an open position by fluid supplied to a door actuator through a driver-operable door control valve 3, an interlock 5 which is operable by the fluid supplied through the door control valve to prevent the transmission control being put into a driving position while the door is in the open position and a sensor 6 responsive to the transmission control to disconnect the door actuator and interlock from the door control valve when the transmission is in the driving condition so that the door can be opened by operation of the door control valve only when the transmission is in a neutral condition. A passenger door (not shown) of a public service vehicle can be opened by compressed air when supplied to an actuating mechanism 1 via door control valve 3. The transmission 4 includes a gear selecting mechanism operable by e.g. a gear-shift lever. A sensor 6 in the transmission senses whether or not the gear selecting mechanism is in a neutral condition and if it is, allows compressed air to be passed to the interlock 5 to lock the gear selecting mechanism in neutral and operate the actuating mechanism 1. The sensor comprises a spool 12 connected to the gear selecting mechanism and having an annular recess 14, which in the position of the spool shown, connects an inlet 15 and an outlet (not shown). The outlet is connected to inlet 10 of the interlock which has a plunger 7 normally retracted (as shown) but movable into a recess 11 in the gear selecting mechanism. Operation.-With the gear selecting mechanism engaged the passenger door cannot be opened since the spool 12 of sensor 6 is not in a position to allow passage of air to the interlock 5. When the gear selecting mechanism is in neutral the spool 12 is moved to position its recess 14 as shown. If the driver-operable door control 3 is set to a " door open " position, compressed air from source 2 is supplied to interlock 5 to move its plunger 7 into recess 11 and to door actuating mechanism 1. The door control 3 must be re-set to a " door closed " position, closing the door, to release the interlock 5 before the gear selecting mechanism can again be engaged.
