Title: Steelmaking in open hearth furnaces
IPC: C21C5/04
Filed: 1973-01-11
Abstract: 1453051 Burner fired open hearth furnaces BRITISH STEEL CORP 11 Jan 1974 [11 Jan 1973] 1566/73 Heading F4B [Also in Division C7] In the end walls of an open-hearth furnace 1 there are mounted burners 7, 8 which are axially movable towards the charge to follow the "melting front"; they may be downwardly inclined, preferably at 7-11 degrees, and may be fired with fuel and oxygen. Alternatively oxygen may be supplied from a separate lance alongside the burner. During at least part of the melting operation, after scrap charging is complete, both burners are fired simultaneously using oxygen to give a high melting rate, the combustion products being exhausted through both of the offtakes 14, 15.
Patent GB-856853-A (GB)
Title: Improvements in or relating to electrical pulse counting apparatus
IPC: H03K21/00
Filed: 1959-01-16
Abstract: 856,853. Electronic counting apparatus. WESTINGHOUSE ELECTRIC CORPORATION. Jan. 16, 1959 [Jan. 17, 1958], No. 1650/59. Class 106 (1). [Also in Group XXXV] A pulse counter comprises a number of bistable stages each comprising two elements and an input pulse sequencing circuit which applies a first input pulse to the odd-numbered stages and the next input pulse to the evennumbered stages, the stages being arranged so that a stage can change from one stable state to the other only when an input pulse is applied to that stage and the preceding stage has already been changed to the second of said stable states. The invention is applied to a system for controlling the temperature of a furnace, Fig. 1. A bimetallic strip varies the output frequency of a generator 12 and a pulse counter 16 counts the number of resultant pulses in a predetermined time. According to how the count compares with a predetermined number so a device 24 controls the supply of fuel to the furnace. Pulse counter, Fig. 2. The pulse counter comprises stages 1-(n), each comprising a pair of NOR elements comprising transistors, the left-hand of which is initially on, i.e. has a more positive output, and the right-hand off. The pulses to be counted are applied to input terminal 70 of a pulse sequence control circuit so arranged that elements 76 and 74 operate to alternate pulses to apply output pulses to the odd- and even-numbered stages 1-(n). The right-hand element of each stage is governed by the left-hand element of the preceding stage. Consequently the first pulse reverses the first stage and so on. The nth pulse reverses the nth stage to bias the first stage again, effect transfer over terminal 89 to the next denomination, and through elements 90, 92, 94 to restore the several stages 1-(n). The several stages may alternatively be restored in cascade manner by a slow-acting pulse applied to terminal 88. A modification of the pulse sequence control circuit is described (Figs. 4 and 5, not shown). Pulse shaper, Fig. 6. An A.C. frequency is applied to a NOR element 114, the output of which is split into a direct path to element 118 and a delay circuit through 120, 122, 128 to the element 118. NOR element 118 produces an output signal only when there is no signal on either of its inputs, so producing a squarewave output dependent only on the values of resistor 124 and capacitor 126 and independent of the A.C. frequency. Count level sensing circuit, Figs. 7, 8. The outputs of the several stages of the counter of Fig. 2 are connected to terminals 15, 17, 19 ... 31, outputs on which have the significance. indicated in Fig. 7. Fig. 8 shows an arrangement whereby when a three-denomination number is exceeded a NOR element 53 has an output. The fuel control device mav be isolated from the counters during count intervals by a circuit described with reference to Fig. 9 (not shown).

Title: Improvements in closure rings for containers
IPC: B65D45/32
Filed: 1953-01-21
Abstract: 743,339. Container closures. COOKSON, W. Jan. 6, 1954 [Jan. 21, 1953], No. 177.8/53. Class 44. [Also in Group XVII] A releasable closure ring 11, Fig. 2, for securing a lid 8 to the beaded edge of a container 6 with the interposition of a gasket 10, has a snap action latching means comprising a wedge-shaped catch and a transverse slit between the catch and the adjacent end of the ring, and a slot in the other end of the ring adapted to engage the catch, the transverse slit providing means for the insertion of a tool to reduce the closure ring to a smaller diameter and force the latch into a secured position. In the first embodiment the ring 11 is formed with an enlarged end 12, Fig. 3, which can be engaged over the other end 13 until a catch 18 engages in a slot 14. A tool can then be inserted at the rear of the hollow member 15 bridging the slot 14 to engage the slit 19 in the other end of the ring 11 and to prise the catch 18 into the hollow member 15. A sealing wire passes through perforations in the sides of member 15 and the hollow catch 18. In an alternative construction, Fig. 7, a catch 32 is initially secured to bear against the front edge 34 of a slot 29 and is prised from this position into a space in the slot 29 between two bridge members 30 and 31. Both constructions are released by prising the ends of the ring apart.

Title: Improvements in automatic alarm systems
IPC: G08B23/00
Filed: 1938-01-19
Abstract: 494,473. Fire-alarm systems. NICOU, H. T. Jan. 19, 1938, No. 1817. Convention date, Jan. 20, 1937. [Class 40 (i)] In a system of the type comprising a normally closed circuit which is interrupted by one of a number of thermally-operated circuitbreakers on the occurrence of a fire to cause the operation of an alarm, the circuit-breakers control the impedance conditions of a circuit so that the location of the fire is indicated or can be ascertained at a central point. For example the protective circuit may comprise a pair of conducting loops including fusible links and bridged by condensers at the positions of these links. When both loops are interrupted a source of pulsating or alternating current is connected manually or automatically between the loops and the amount of current flowing indicates the number of condensers between the source and the break. The condensers may be graded in size to compensate for the resistance of the loop circuits and may be provided for only some of the circuit breakers. They are preferably moulded in insulation in the base of the circuit-breakers. In a modification the circuit-breakers are shunted by resistances having individual values. Alternatively the circuit breakers may modify the inductance of the protective circuit. In the arrangement described in detail, relays Ra, Rb are normally energized over a pair of protective loops a, b. The relapse of both relays causes the operation of an alarm in known manner. The circuit breakers, Figs. 2 and 3 (not shown), are arranged to connect the loops together on both sides of the break and consequently, when the relays fall back, circuits exist for measuring instruments Av, Ab, the deflection of which depends on the position of the break. A number of protective loops with individual relays Rb, Ra may be associated as at 8 with the same measuring instruments. In a modification, several loops are normally connected in series so as to share a single pair of relays, a loop being disconnected from the series when a break in it occurs and the other loops remaining connected to the relays. Where two sections sharing the same indicators break at the same time they are connected to the indicators manually or automatically one at a time. It is stated that only every second or every fifth of the thermal circuit breakers need have bridging contacts. Specification 409,617 is referred to.

The signal, which may be a lamp or sound source, may be replaced by a lower intensity signal when cut-off.  As shown the 3-way spool valve 13 (Fig. 4) is operated by a manual lever 32 with a first pin movable in a fixed slot 39 in a support 31 against the restraint of a spring g and a second pin 41 engageable in a notch 40 in its central position or against an inclined surface h 1  or h 2  of the support 31 when displaced to close one circuit. The device 10 includes a valve spool 42 (Fig. 3) responsive to a pressure difference between its ends to actuate a switch to energize an electromagnet 44 which closes a switch 45 to energize a lamp 11 and maintain energization of the electromagnet. When the lever 32 is moved a switch i 1  is actuated to cut-off the lamp 11 and electromagnet and preferably a switch c 1  is closed to energize a lower intensity lamp v. Alternatively (Fig. 2, not shown) displacement of the lever 32 adjusts a rheostat to dim the lamp 11.
