IPC: H04Q3/00
Filed: 1957-12-14
Abstract: 872,301. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Nov. 17, 1958 [Dec. 14, 1957], No. 38965/57. Class 40 (4). In a tandem exchange having incoming 4-wire lines with access over group selectors to outgoing 4-wire or 2-wire lines, incoming voicefrequency pulse trains are repeated as D.C. impulses in a loop which includes part of a speech path whether the outlet is a 4-wire or a 2-wire circuit. Voice-frequency pulses received over wires CD of the incoming trunk circuit of Fig. 1 operate receiver 1VFR over buffer amplifier 1BA and each pulse operates relay 1A. Relay 1B is operated by an initial seizing pulse and stays operated so that relay 1CD holds up during pulse trains and forms an impulsing loop for relay A which repeats the pulses passed on by relay 1A. A single digit is registered in a trunk group selector TGS to mark the wanted group of outlets an idle one of which brings up relay H which is held by earth over the P-wire. Subsequent behaviour of the circuit depends on the kind of connection obtained. If the connection is to a 2-wire line the contact banks A, B are not used so that relays 1PC and 1FW remain unenergized and pads 1AP and 2AP and the hybrid 1HA remain connected. Should it be necessary to remove the pads earth is returned over the A bank. A line-splitting relay 1SP (not shown) is operated to permit tones to be sent back over the return path but is released to enable modulator 1SM to return a voice-frequency reply signal. If the connection is a 4- wire connection through the exchange, H responds to negative battery in the outgoing trunk circuit shown in Fig. 2 where an impulse relay 2A is connected up in place of the relay A of Fig. 1. Transformer 4TR is connected over the A and B banks to transformer 6TR causing 1FW and 2FW to operate and disconnect the hybrids 1HA and 2HA. Relays 1PC and 2PC are connected in the energizing circuits of 1FW and 2FW but do not operate so that the pads remain connected. Voice-frequency digital impulses incoming to the circuit of Fig. 1 are repeated by relays 1A and 2A and each break impulse of relay 2A releases line-splitting relay 2SP of Fig. 2 and energizes relay 2SX to connect modulator 2SM and send a voice-frequency impulse over the outgoing trunk. Reply is indicated by a voice-frequency pulse to which receiver 2VFR responds operating relay 2VF. Relay 2DD energizes to reverse polarity in the backward path and operate relay 1D which in a manner not described releases 1SP to split the line and revert a voice-frequency reply signal from modulator 1SM. The outgoing trunk circuit may be taken into use over the 4-wire path L4SM from a manual position, or over the 2-wire path LSM. When seized over LSM a separate circuit may be provided to operate relay 2PC and switch out the pads 3AP and 4AP. The incoming 4-wire paths may be radio or line carrier links.

Title: Improvements in or relating to Bridge Cranes
IPC: B66C13/06

Abstract: 1,183,126. Preventing swinging of loads in bridge cranes. KONE OSAKEYHTIO. 25 Aug., 1967 [25 Aug., 1966], No. 39162/67. Heading B8B. [Also in Division H2] A bridge crane comprises a trolley running on the bridge and having a drum from which extends a cable or chain provided with a hook, a prime mover for moving the trolley, and synchronization means for controlling the prime mover such that when the crane operator controls the prime mover so that the trolley is accelerated or decelerated to alter its movement relative to the bridge the prime mover automatically accelerates or decelerates the trolley by the same amount and in the same direction after a time which is half the time of the period of the oscillation of a load on the hook produced by the first said acceleration or deceleration, so as to effectively cancel the said oscillation. The prime mover may be a twospeed squirrel-cage motor having the speed ratio of 1: 2, the motor speeds being used respectively for the two accelerations with the second one actuated by the synchronization means, and the operation being reversed for deceleration. In the control circuit shown in Fig. 4 movement of the drum 9 changes the setting of the potentiometer Rp to alter the charge on the condenser C to accord with the length of cable or chain unwound from the drum. When measuring of half the oscillation time begins, the switch 10 is changed over so that the condenser discharges through the resistance R 3 , and a time relay A operates the motor again when the condenser charge has reached a predetermined value. In the control circuit shown in Fig. 5 which is used for short impulse driving of the trolley, the switch A is closed when the motor is actuated by the operator, to charge the condenser C in dependence on how long the motor is actuated, the charging current passing through the diode D I  and transistor Trl. When the relay A, Fig. 4, operates after the appropriate time the switch B is closed and the condenser discharges through the diode D, and the transistor Trl. The current also passes to the transistor Tr 2  to direct its collector tension to zero, and when the condenser is discharged the collector tension rises to that of the current source and this may be used as a signal for the motor to stop. If a large load causes the trolley to slip during the first actuation of the motor the discharge of the condenser may be made dependent on the distance travelled, e.g. by providing a switch controlled by a magnetic toothed wheel on the motor.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B18/16
Filed: 1962-10-17
Abstract: In the manufacture of flat glass during which the glass is in contact with a molten metal a protective atmosphere is maintained above the molten metal comprising a major portion (i.e. more than 50% by volume) of a gas which is inert or substantially inert at the temperature existing above the molten metal, and a proportion of a reducing gas to react with any oxygen present in the atmosphere over the molten metal, and thereby to inhibit reaction of contaminants at the surface of the molten metal. In the manufacture of flat glass wherein a ribbon of glass 28 (Fig. 1, not shown), is advanced along the surface of a bath of molten metal 12 the molten metal, e.g. tin, is contained within a tank 13, 14, 15, and above the glass is a roof structure with end walls 18 and 19 terminating near the glass surface, and an intermediate wall 27 such that there are headspaces defined above the glass.  A further roof 24 enclosed the inlet to the bath.  Inlet pipes 20a, 20b, 20c allow for the passage of an inert gas into the headspaces above the glass surface. It is preferable that the gas compositions are nitrogen or argon admixed with 2 to 8% of hydrogen in the inlet region, 3 to 10% of hydrogen in the region between walls 18 and 27, and 0.25 to 3% of hydrogen in the outlet region.  The presence of the hydrogen causes any contaminants in the protective atmosphere, e.g. oxygen and sulphur, to react therewith in preference to the molten tin at the surface thereof.  The hydrogen may be passed through the molten tin prior to its entering the headspaces. A catalyst may be contained in the outlet headspace, and also the protective gas in this region may be specially preheated.
