Title: Gas measuring apparatus and methods
IPC: G01N21/35
Filed: 1975-09-04
Abstract: 1500739 Infrared respiratory gas analyzer DRAGERWERK AG 4 Sept 1975 [5 Sept 1974]  36536/75 Heading G1A The concentration of carbon dioxide in respiratory gases is monitored by infrared absorption measurement on the direct gas flow, the detector output throughout or at one part of the respiratory cycle being divided by the output at another part of the cycle. The quotient signal is logarithmed to provide an approximately proportional measurement. Either the continuous detector output valve or the maximum CO 2  content value (obtained during the exhalation part of the cycle) is divided by the minimum value. The infrared analyzer comprises a circular or square cross-section holder 17, for the plastics flow tube 16, which is heated by a positive temperature coefficient resistor to avoid condensation on the inside walls of tube 16, the holder also carrying a lamp 19 emitting infrared, means 20 for modulating the beam an interference filter 18 passing infrared at 425 Á so as to be sensitive to C02 absorption, lens system 26 and photo-cell 23. The detector output is fed to maximum and minimum value stores 3, 4 and to a respiratory cycle phase detecting circuit 5 which includes a differentiator, and is used to control the operation of stores 3, 4 and the feeding of their values to calculating circuit 6, which also receives the detector output direct. The logarithm of the desired quotient signal is indicated or applied to a recorder or oscillograph.

Title: Improvements in machines for cutting coal and like minerals
IPC: E21C25/06
Filed: 1957-11-25
Abstract: 845,322. Mining machines. EICKHOFF MASCHINENFABRIK UND EISENGIESSEREI GEB. Nov. 25, 1957 [Nov. 28, 1956; Jan. 5, 1957], No. 36593/57. Class 68(1). A drum type cutting machine in which the drum 5 is rotatable in opposite directions and is provided with cutting tools 13, having oppositely directed edges 18 and 19, the tools being arranged to pivot with respect to the drum 5 through limited paths. A pick 13 is mounted in a holder 11 secured to a pin 10 and has a tail 12 engaged in a notch 9 in the external surface of an internally toothed gear ring 7, which is coaxial with and free to rotate relative to the drum 5. The ring is driven by a pinion 8 and when the direction of rotation of the pinion is reversed, the holder 11 pivots in the rectangular opening 17 until its movement is stopped by one of the edges 20 and the whole drum then begins to rotate. Tugs 14 on the tool-holder close the appropriate part of the opening 17 to prevent cut material entering the mechanism. In the example shown each pick is mounted in a separate holder keyed to the pin 10, only one holder being driven from the gear ring 7. In a modification the picks are mounted in a single holder of suitable length which is free to pivot on the pin 10, which is fixed in the walls of the drum.

Abstract: 340,728. Gas meters. THORP, F., BUTTERWORTH, E., and ROTARY METER CO., Ltd., Fitzalan Street Works, Kennington Road, London. Nov. 29, 1929, No. 36628. [Class 54.] A wet gas meter comprises two pairs of interconnected bells c, d and e, f oscillating or reciprocating in a casing a containing sealing liquid, each bell being formed with gas inlet, outlet, and measuring compartments and the passage of gas from an inlet pipe 27 below the bells to an outlet pipe 33 leading from the space in the casing above the sealing liquid being controlled by the movement of the bells without the use of distributing valves. In the meter shown the bells c, d and e, f rock on two spindles b, and pipes 28 .. 31 connect the inlet compartments y, 21, u, w with the outlet compartments 22, 20, x, v and the measuring compartments q, r, t, s respectively. The inlet pipe 27 communicates by branches 25, 26 with inlet spaces 23, 24 around the spindles b, the lower parts of the walls between the inlet spaces and the inlet compartments and the lower parts of the side walls of the outlet compartments being cut away so as to allow the passage of gas when the cutaway portions are raised above the level of the sealing liquid. As the cut-away portions of each bell rise above the sealing liquid gas is admitted to and discharged from the two bells on the other spindle, the sequence of operation being controlled by links g, h connecting the bells with arms i on the spindle i of the index mechanism. Modifications are described in which the cut-away portions of the gas inlet compartments are in the radial walls between the gas inlet and outlet chambers and in which the bells reciprocate vertically.

Filed: 1964-09-08
Abstract: 1,016,210. Testing insulation. STANDARD TELEPHONES & CABLES Ltd. Sept. 8,1964, No. 36740/64. Heading G1U. In a method of detecting electrical leakage paths through a sheath of insulating material enclosing a conductor, the conductor is moved longitudinally past a barrier of flexible electrodes which comprises at least one row of electrodes of diverse lengths arranged such that their ends define part of a passage substantially conforming to a portion of the sectional shape of the sheath. The electrodes and conductor are connected to opposite terminals of a test voltage source, and any flow of current in the circuit, which indicates an insulation fault, is indicated on a suitable meter. In an apparatus 1 (Fig. 1) for carrying out the method, the flexible electrodes 13 consist of ball chain and are suspended from a frame 12 across the path of the sheathed conductor 8. A rigid electrode 18 having a U shaped cross section and also connected to the test voltage source is pressed against the underside of the sheathed conductor, and various sets of flexible electrodes of different lengths are suspended between the parallel limbs of this electrode so that apertures of different shapes to permit the passage of different shaped conductor sections are provided (see Fig. 3). The arrangement improves the efficiency with which large diameter sheaths are tested, since these sheaths will not force the flexible electrodes apart, as would happen if all the electrodes were of the same length.

[Class 40 (ii).] Optical apparatus and records.-Sound is recorded or reproduced on or from a trace T on a film A, then on or from a trace T on a second film B and is continued on or from a second trace on the first film A and so on The films thus have a plurality of parallel traces T side by side. While one film is being used the second film is made ready to continue the process, such as being wound backwardly. To avoid rewinding the traces on each film may run alternately forwardly and backwardly. The films may have notches to control the operation of the reproducers and the change over from one film to the other. Thus the film A is set in the machine with the notch AN1 at a definite position and the winding gear is started. After a suitable interval of time a notch AN2 switches in the recording gear. Towards the end notches AN3 start up the second film B, notches AN4 fade out film A and fade in the film B, and notches AN5 stop film A, reverse it, and rewind it back to the notch AN1, and at the same time the recording or reproducing apparatus is moved laterally off the film. Similar notches are formed in the film B. More than two films may be employed.
