Abstract: 1,182,263. Continuous casting. ASHMORE, BENSON, PEASE & CO. Ltd. 16 May, 1967 [16 May, 1966], No. 21714/66. Heading B3F. In a continuous casting process in which molten metal poured into one end of an openended mould, is continuously withdrawn in the form of a casting from the other end, the mould is formed in two parts, the upstream part 61 being made from graphite and the downstream part 64 from a material of high conductivity, and cooling means is provided whereby the temperature in the mould parts is controlled to effect initial solidification of the metal in the graphite part, the mould being reciprocated in the direction of withdrawal of the casting. The mould 47 is mounted on a trolley 12, with its casting axis 50 horizontal, and a tundish 48 mounted on slides 51 is urged by spring unit 52 into engagement with the mould, the trolley 12 being reciprocated by hydraulic means 46. In operation, molten metal 54 supplied to the tundish 48 from a degassed ladle 55 is fed through an outlet 58 into the mould cavity, the outlet being plugged by an extension 78 on the starter bar 77 prior to the commencement of the casting operation. The molten metal in the tundish is heated by a burner 56 and through the opening of which may also be supplied non-reactive gas 57 to screen the molten metal therein and which passes, through the tundish feed opening to screen the incoming stream 54. The casting produced is guided by roller means 74 through a spray cooling chamber to a shearing device whereafter the sheared lengths are transferred to a storage and cooling bay to await further processing. A diagrammatic layout of a plant incorporating the casting apparatus is described which includes means for handling the finished casting and for movement and storage of the mould and tundish for repairs and replacement.

Title: Manufacture of artificial fibres and films from cellulose esters
IPC: D01F2/28
Filed: 1930-07-18
Abstract: The solutions obtained by esterifying cellulose in liquid sulphur dioxide, as described in Specification 301,036, [Class 2 (ii), Cellulose &c.], are worked up into artificial fibres or films by a combined dry and wet spinning or extrusion process, without first isolating the cellulose ester.  For example, a solution comprising liquid sulphur dioxide 55, cellulose acetate 22, acetic acid 16, water 5-6, and a catalyst 1-2 per cent, obtained as described in Specification 301,036, is filtered and dry-spun in known manner at ordinary, reduced, or elevated temperature.  The coagulation of the more or less swollen threads so obtained, comprising cellulose acetate 50, acetic acid 33, water 12, and a catalyst 5 per cent, is then completed in a bath of water or a salt solution or an organic coagulant, and the threads are wound, bleached, washed and dried.

Title: Display apparatus
IPC: G06F3/02
Filed: 1976-05-26
Abstract: 1522763 Keyboards and displays INTERNATIONAL BUSINESS MACHINES CORP 26 May 1976 [10 June 1975] 21832/76 Heading G4H In display apparatus, means operate to change the locations at which characters are displayed without changing the locations at which they are stored in a random access memory when and only when a fresh character is entered into the memory, the setting of an address counter selecting characters for display being changed whenever a fresh character is entered into the memory. A clock-driven control counter 16 scans a matrix 10 of key switches via decoders 30, 32 to set a key latch (bottom right in Fig. 2) to cause a gate 22 to produce a "load counter buffer" signal which loads the scan count into a counter buffer 14. If the key keeps the key latch set, the next time the same count is reached (detected by a comparator 34), a gate 26 produces a "load RAM strobe" signal to enter the contents of the counter buffer 14 into a RAM (80, Fig. 3, not shown) at an address specified by a load address counter which is incremented for successive entries. Detecting the same key closed on two successive scans (see above) provides leading edge bounce protection. The counter buffer is reset from a gate 28 when the previously scanned key is no longer closed, thus providing trailing edge bounce protection. Gate 28 also resets various latches (which were set from the gates 22, 26 to prevent them producing further outputs to load the counter buffer and RAM). Thus N-key lockout and 2-key rollover are provided. The RAM can also be loaded from a computer. A display address counter (initialized via a complementer from the control counter 16) reads the keyed characters from the RAM for display on a 7-segment LED multi-position display, the positions of which are selected in synchronism by the decoder 30 as the display address counter is decremented. The display address counter is incremented at each key entry into the RAM, so the most recently entered character is displayed at the right-hand end of the display, the next most recently entered next to it, and so on.

Abstract: 632,794. Electromagnetic switches sparking preventing in switches. KESSELRING, F. July 23, 1946, No. 21970. Convention date, Aug. 7, 1945. [Class 38 (v)] In an electromagnetic switch for alternating current circuits, the separation of the contacts commences slightly before current zero, so that when the arc is extinguished at the current zero, the separation of the contacts is sufficient to prevent the re-striking of the arc. In Fig. 2 the switch comprises metallic plates 1, 2 and an insulating member 3 forming a sealed container, which encloses an energizing coil 10, a series coil 7 and a pivoted combined armature and contact member 4 biassed by a torsion spring 5 against stops 6. To close the switch, the coil 10 is energized from a D.C. source 11 causing the member 4 to turn against the spring to complete the main A.C. circuit from i through plate 1, coil 7, fixed contact 8, member 4, and plate 2. To open the switch the coil 10 is de-energized by the opening of a synchronously controlled switch indicated at 12, and the member 4 is turned by the spring 5 to open the A.C. circuit as the current approaches zero. In a modification, Fig. 3, two armature and contact members 22 cooperate with fixed contacts 20, 21 to provide parallel breaks. The members 22 are spring- biassed to the closed position and are opened when the coil 36 is energized from a D.C. source by means of a synchronous control device. A series disconnecting switch (not shown), may be provided. The insulated members 23, 24 carrying the fixed contacts are surrounded by laminated iron packs 25, 26 which are stated to prevent the parallel arcs forming a single arc. In each of the above examples the sealed container may be filled with gas, such as hydrogen, under pressure, or it may be evacuated. The Specification in setting out the theoretical considerations for the above constructions, gives dimensions for the combined armature and contact members and states that the opening of the switches commences at the earliest at 10<SP>-4</SP> seconds before current zero. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 632,843. This subject-matter does not appear in the Specification as accepted.

Abstract: 170,656. Marconi's Wireless Telegraph Co., Ltd., (Goldsmith, A. N.). July 22, 1920. Modulating systems and apparatus; audible reception of unmodulated continuous waves; coupling oscillating and radiatinq circuits; coupling aerial and detector circuits.-The inductance value of a circuit either receiving or transmitting continuous-wave signals is varied at an audible frequency, so as to impart a tone characteristic to the signal energy, by means of a toothed wheel, which in receiving is rotated in close proximity to an inductance coil, or in transmitting-systems is interposed between two coupled inductances. As shown in Fig. 1, the inductance of a coil C in the receiving-aerial A is continuously varied by means of the toothed disc G, Fig. 2, driven by a motor H. This gives rise to periodic variations of frequency producing an audible note in the. detecting-circuit E. Fig. 4 shows the arrangement applied to an arc transmission system. The arc L, supplied from a generator P, is directly in the antenna, the tone modulation being impressed by the wheel G, which varies the inductance of the coil C. As shown in Fig. 7, balancing coils S, T are used to compensate for the mutual inductive variation between the coils D, F with the object of maintaining at a steady value the load upon the generator P. The circuit S, U forms an artificial aerial having the same constants as the antenna A. The coils S, D are so arranged that simultaneously one D is cloaked by a tooth of the wheel G, whilst the other S is not, as shown in Fig. 9. Another arrangement is described in which undesirable variations, liable to be set up in the oscillating arc circuit by the movng teeth, are eliminated.
