Title: Improvements in interlocking devices between valves or cocks, and the pipe connections thereto
IPC: F16K35/10
Filed: 1926-05-17
Abstract: 278,033. Okill, J., and Tate, J. R. May 17, 1926. Locking-catches; preventing disconnection of pipes from valves.-An interlocking-device be tween a valve or cock and the pipe connection thereto to prevent disconnection of the pipe whilst the valve is open comprises a coupling. nut F; Fig. 1, provided with an overhanging flange f<2> formed with a gap f<3> which, when the valve is open, registers with and engages a stop d<5> on a double-sided sliding locking-frame D movable with the valve spindle B, as shown. In an alternative arrangement a projection f<6>, Fig. 4, on the coupling nut F<1> lies in the path of the rotary valve handle D<1> when the valve is open. In this position also the nut F<1> abuts against a spring-pressed double slider frame g<1> carrying a locking-pin g<5> which is thereby held out of engagement with the disc d<9> of the handle, so that the valve is free to be operated. When, however, the valve is turned to the closed position, a locking recess or hole d<8> is brought into the axial line of the locking pin g
. In this position the coupling nut F<1> is free, and when this is un. screwed the springs g<2> project the frame to the right hand, thereby engaging the pin g<5> with the recess d<8>. The valve is consequently locked in its closed position until the coupling is again completed.

Title: "improvements relating to methods and apparatus for impedance measurements"
IPC: G01R27/02
Filed: 1955-05-02
Abstract: 769,806. Impedance measurements. SUN OIL CO. May 2, 1955 [Aug. 12, 1954], No. 12645/55. Class 37. In an apparatus for comparing the values of two impedances, such as 46 and 48 in Fig. 1, of which one may be variable and both of which form parts of individual circuits having a common transmission line, such as the centre line 18 of a coaxial cable 20, of which the distributed capacitance is such that uncontrollable changes of reactance may be expected therein in excess of changes in magnitude of said impedances to be compared, means such as a high-frequency oscillator 2 are provided to excite the circuits to the impedances 46 and 48 and means such as a lowfrequency supply of the order of 60 cycles per second, at the transformer 10 act to render the circuits to the impedances 46 and 48 alternately excited so that a detector circuit having in its final stage a pair of triodes 72 and 74 of which the anodes are excited by a transformer 76 at, the same frequency as that for transformer 10, give on a measuring instrument M a comparison of the impedances 46 and 48. The manner in which the exciting and switching circuits are combined is indicated diagrammatically in Fig. 3. A, B, and C represent the high-frequency exciting and low-frequency switching wave forms on their own and as combined. After partial rectification by a diode 60 in the detector circuit of Fig. 1 in which the low-frequency characteristic is greatly reduced in amplitude, the wave form is of the kind shown at E so that the triodes 72 and 74, by being matched to the switching frequency, generate a signal on the instrument M which is proportional to the difference of amplitude F and therefore to the two impedances C1 and C0. The switching may be carried out electromechanically, as shown in Fig. 9, in which the low-frequency supply 212 energizes a coil 210 to move a contact arm alternately connecting the circuits to the two impedances 218 and 220. Figs. 13 and 14 show a typical application of the invention in -which it is desired to measure the depths of a column of oil 325 and water 328 in a tank 322. The tank has a vertical conducting metal tube 332 in which extend two lengths of insulated conductor of a metal rod coated with a material such as teflon, the upper length 338 being always surrounded with oil, but the lower length having a variable water-oil immersion. The proportion of oil and water in the tank may be determined by a circuit such as that shown in Fig. 14, the capacitances 382, 384 and 386 representing the capacitance between tube 332 and conductor 336, the water 328 and the conductor 350 and the tube 344 and conductor 346. These capacitances may be compared with a variable capacitance 388 driven by the receiver of a selsyn unit coupled to a motor 420 linked to the circuit of diodes 408 and 410.

Title: Improvements in and relating to combination records for automatic musical instruments and electrical sound reproducing apparatus
IPC: G10H3/06
Filed: 1929-04-25
Abstract: 310,430. Zoppa, A. E. April 25, 1928, [Convention date]. Sound-records combined with player-piano and like records; sound-recording apparatus associated with automatic musical instruments; electric records.-A record or tune-sheet for controlling the working of an automatic musical instrument, such as a player-piano, is combined with a photographic, electro-conductive, magnetic, or other record for reproducing sound by electric or photoelectric means. Figs. 3 and 5 show apparatus for producing a photographic sound-record on the margin of a piano music-sheet. The sheet 15 is enclosed in a chamber 25 which contains the usual tracker-bar 31 engaged by the sheet, the chamber having a partition 26 forming a dark compartment 28 into which the ends of the rolls 29, 30 and the sensitized margin of the sheet protrude. The front of the main part of the chamber 25 is closed by a transparent red or yellow panel 37, so that the indications on the music-sheet are visible, but actinic rays cannot enter the chamber. The sensitized part of the sheet passes by a lens 22 in front of a lamp 16, which is connected in circuit with a microphone 18, a colour-filter 23 being also provided if necessary. Sound transmitted by the microphone thus causes variations in intensity of the light, which are recorded as the sheet travels. A record of piano music is made, as perforations in the sheet, prior to the photographic sound-recording, and the piano record is played, preferably very softly, whilst tha voice or other music (to which the piano music forms an accompaniment) is being recorded by means of the microphone. Fig. 1 shows a portion of the perforated musicsheet 10 having a photographic sound-record 14 thereon. Instead of making a sound-record of this type, the record may be produced as an electrically-conducting coating of varying width, as shown at 53, Fig. 2. The Specification as open to inspection under Sect. 91 (3) (a) also describes and shows apparatus for reproducing sound from both kinds of records. This subject-matter, which does not appear in the Specification as accepted, is comprised in Specification 310,429.

Abstract: 858,802. Photographic contact-printing apparatus. ARNOLD, A., and RICHTER, R., [trading as ARNOLD & RICHTER KOMM.- GES.]. April 23, 1957 [April 20, 1956], No. 12991/57. Class 98(2) In a printer for continuously moving film 1, punched tape 33 controls the gain of a control amplifier 22 which provides the input to a power amplifier 23 energising the gas discharge printing lamp 21. The control amplifier 22 has a constant amplitude input from power pack 24 and its gain is controlled by pulses from controller 27. Punched tape 33 may be moved step-wise by controller 27 when this is actuated by photoelectric scanning of opaque marks on film 1 or by momentary closure of switch 32 as roller 30 engages with a notch in the film margin. The amplifier control pulse produced on actuating the controller 27 depends on the combination of holes in the tape. If rectifier 34 is omitted, the width of the printing slit is made such that the exposure time is a multiple of the period of the energising A.C. Alternatively, for a D.C. lamp, only part of the power may be controlled by the amplifiers, a by-pass current energising the lamp continuously at the lowest intensity required. An arrangement for simultaneously controlling three lamps having colour filters (Fig. 2, not shown) is also described. Preferably a Xenon printing lamp is used.
