Title: Method and device for sampling molten metals
IPC: G01N33/20
Filed: 1968-02-27
Abstract: 1,218,988. Sampling metals. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. Feb.27, 1968 [Feb.27, 1967, No.9397/68. Heading C7D. In a method and apparatus for the determination of elements escaping in gaseous form from a molten metal sample the whole of the latter is while still liquid poured into a funnel having such an outlet dimension that the metal solidifies rapidly, whereby a part of the latter remains in the funnel and prevents access of air. Metal passing through the funnel is collected in a container placed in a receptacle filled with neutral gas. Preferably the receptacle is closable, being opened only to allow inflow of metal, at which time the opening is swept by neutral gas, while the funnel may also be swept by gas prior to entry of the metal. As illustrated, water-cooled vessel 1 contains crucible 4 which may be heated by means 5, 6, while neutral gas is introduced at 41. The opening 9 may be closed by sliding obturator 21, on either side of which are screens of neutral gas from inlets 40,17. In operation metal is poured in through the funnel which is then blocked by solidified metal; that metal which passes through is collected in pre-heated crucible 4 where it may be retained in a molten state, the gaseous elements evolved being withdrawn through outlet 18 for analysis.

Title: Improvements in vacuum type circuit interrupters
IPC: H01F29/04
Filed: 1967-02-28
Abstract: 1,129,483. Vacuum switches; transformers. GENERAL ELECTRIC CO. 28 Feb., 1967 [8 March, 1966], No. 9472/67. Headings H1N and HIT. The bursting of vacuum switch 26, when liquid in which the switch is immersed has leaked into the switch envelope 50, is prevented by disabling the switch operating mechanism 28 when a rise in pressure occurs in the switch envelope. In the transformer tap changing arrangement shown, a passage 54 extends from the interior of the envelope through the stem 53 of the fixed switch contact 51 to an expansible chamber 60 on the outer end of the stem 53. When the pressure in the envelope 50 increases, a changeover switch 34 is operated by the chamber 60 to open contacts 63 in series with the push-button switch 33 which initiates a tap change operation. Thus opening of the contacts 63 prevents energization of the drive motor 30 of the tap changer unless a tap changing operating cycle is in progress, in which case the cycle is completed before the opening of contacts 35 breaks the motor circuit. The switch 34 also closes contacts 64 to operate an alarm 65. The vacuum switch provides, in effect, the arcing contacts for an otherwise conventional tap changer and the arrangement disclosed may be mounted directly in the transformer oil.

Abstract: 920,772. Phase-shift radio signalling. ROBERTSHAW-FULTON CONTROLS CO. March 19, 1959 [April 28, 1958], No. 9607/59. Class 40 (5). A phase-shift communication system in which the receiver comprises means for deriving directly from the modulated carrier wave, a reference signal for comparison with the modulated carrier wave in a phase detector, said means including a circuit resonant at a harmonic other than the first) of the carrier, and a frequency divider. Arrangements for one, two three and four channel transmission are desoribed. The incoming signal, in which the carrier is modulated in two phase positions, to the receiver (Fig. 2) is fed directly to one input of a phase detector 42 and also through a full-wave rectifier 44, resonant circuit 46 tuned to the second harmonic of the transmitter output, frequency divider 48 dividing the output of the tuned circuit by two to give the reference frequency, to the other input of the phase detector. It is stated that no phase modulation of the reference signal occurs. The receiver circuit is described (Fig. 4, not shown) and the modulating stage for the transmitter is also described (Fig. 3, not shown). A transmitter and modulator for providing a three-phase position signal are described with reference to Figs. 6, 7 (not shown), and the receiver is shown in Fig. 8. The input path to the phase detector 126 for supplying a reference signal thereto of waveform identical to the unmodulated carrier comprises a squaring circuit 128, differentiating circuit 130, a circuit 132 tuned to the third harmonic of the carrier and a frequency divider 134 and phase shifter 136 to give the required signal. In yet another embodiment for a four-phase position signal the modulator for the transmitter is described (Fig. 10, not shown) the receiver again comprising means for re-constituting the unmodulated carrier as a reference signal (Fig. 11) and comprises squaring and differentiating circuits 174, 176 and a circuit tuned to the fourth harmonic of the carrier, a frequency divider 178 to obtain the correct frequency. A portion of the output from the divider is applied directly to a 90 degrees phase-shifter 180 and also to a phase detector 170, the phase-shifted voltage being then applied to an auxiliary phase-detecting stage 182, one-third of the output voltage therefrom being added to the total output from detector 170 in circuit 184. The 0 degrees and 180 degrees phase displacements in the carrier will therefore yield positive and negative outputs and the 90 degrees and 270 degrees components will also yield positive and negative outputs but of <SP>1</SP>/ 3  the magnitude.

Abstract: 271,052. Anchor Cap & Closure Corporation, (Assignees of Mullen, G. W.). May 12, 1926, [Convention date]. Heating by circulation of fluids.-To counterbalance the internal pressure produced in sterilizing or cooking food by heating in hermetically sealed containers 25, the containers are inserted in a retort &c. 10 in which air or other gas is entrapped and into which a heating medium containing water vapour, e.g. steam, under pressure, is introduced. In the construction described, the containers 25, which may be exhausted of air, are inserted in perforated baskets 26 resting on a support 34 within the retort 10 to which the cover 20 is then secured by bolts. The retort is heated to the desired temperature by steam applied through tube 35, valve 37, tubes 39, 40 and needle valve 41. The valve 41 comprises a tube 44, Fig. 3, screwed into the retort wall, into which a spindle 45 adjustably screws and is secured by a nut 47. The pointed end of spindle 45 engages a conical seating 49 fitted into tube 44 and having a deflector 50 which directs the steam tangentially into retort 10. A number of these valves may be provided at different positions. The steam is kept saturated by maintaining a constant level of water 30 by means of a steam trap 29 which may have a float-controlled valve which is opened to allow excess to run off when the condensed water reaches a certain high level, and closed at a certain low level. The trap 29 is connected to the retort 10 above the water level by a pipe 32 to prevent air lock. A byepass is also provided, enabling the water to be drawn off without entering the trap 29. When the desired temperature is reached, the supply of steam to the retort 10 is decreased or cut off by a valve 59 automatically operated by expansion of gas in a tube 56 within the retort. Pressure is automatically released above a certain value by a valve 62 set by a member 53. A safetyvalve 83 set at a higher value than valve 62 is also provided. When sterilization has been completed, cooling water is supplied to the retort through pipes 67, 90. The retort is provided with a thermometer 100 and pressure gauge 101.
