Title: Improvements relating to means for measuring and indicating temperature from a distance
IPC: G01K1/02
Filed: 1929-01-17
Abstract: 325,950. Griffiths, E., and Snow, A. Jan. 17, 1929. Thermometers. - In a Wheatstone-bridge measuring instrument applicable to the distant measurment of temperatures by means of electric resistance thermometers, the testing arm includes a controllable resistance and a self-opening switch in a battery lead, the resistances and switch being so arranged that the resistance cannot be set while the switch is open. The Wheatstonebridge may be used in association with a temperature-measuring device comprising a number of electrical thermometers and two selector switches so arranged that any one of the thermometers can be inserted in the bridge circuit. In the circuit shown in Fig. 2 the test arm comprises three rheostats d, e, f with which are, associated switches d<1>, e<1>, f<1> in the circuit of the battery g. Preferably the contacts d<2>, e<2> operated by the switches d<1>, e<1> have ballast resistances r<4>, r<5> in series therewith. Fig. 3 shows a. combined rheostat and switch constructed as a single unit. The rheostat comprises a base 1 carrying the contact studs 2 and battery switch 4, a cover 8, and a rotatable sleeve 11 carrying brushes 5, 6 bearing on the cover and the studs respectively. The operating knob 9 carries a spindle 10 adapted at its lower end to close the switch 4 and also carries a dog-clutch member 12 adapted to engage a similar member 13 on the sleeve 11. Depression of the knob thus closes the battery circuit and also brings the dogs into engagement to enable the rheostat to be set. The total resistances of the rheostats d, e are ten times as great as those of the rheostats e, f respectively.

Title: Improvements in and relating to horizon gyroscopes
IPC: G01C19/44
Filed: 1943-02-06
Abstract: 565,599. Gyroscopic apparatus. JACK & HEINTZ, Inc.. Feb. 6, 1943, No. 2004. Convention date, Feb. 21, 1942. [Class 97(iii)] In a gyroscopic artificial horizon erected by air jets under the control of erection pendulums, disturbance and false erection torques due to acceleration are avoided by the employment of acceleration responsive means individually operable with respect to each air-jet port so as to cover in response to acceleration, only those air-jet ports which are further opened by the effect of the acceleration on the erection pendulums. In Fig. 2 is shown a sectional view in plan of the erector casing with the parts in the normal undisplaced position, and Fig. 4 is an elevation with the parts displaced by an acceleration force. The erector casing has on each of its four sides an outlet port 13 through which an air jet issues to apply the erecting torque in usual manner, each opposite pair of jets being controlled by an apertured stirrup-shaped erection pendulum 20 or 21. Between the erection pendulums and the erector casing are arranged four acceleration pendulums 31 ... 34 which are normally biassed away from their natural position of repose by stops 45 so as to be unaffected by small inclinations of the casing. In this position, openings 41 ... 44 in the acceleration pendulums register with the ports 13. Stops 46 limit the movements of the two sets of pendulums in the opposite direction. In action, during normal unaccelerated operation, the erection pendulums respond to slight deviation of the rotor casing from the vertical and apply the correcting torques as required, the acceleration pendulums remaining against their stops 45. During accelerations, the acceleration pendulums affected thereby move away from their stops and close the air ports erroneously opened by the erection pendulums thus avoiding the imposition of spurious erecting torques.

Title: Process for the indication and measurement of gases and vapours in air or other permanent gases
IPC: G01N27/74
Filed: 1954-01-26
Abstract: The presence or quantity of gases and vapours in air or other permanent gases is determined by passing the mixture through a solid, preferably granular, absorbent (including adsorbent) material arranged in an electromagnetic alternating field, the variation of which is determined.  Suitable absorbents are active carbon or silica gel, or if organic solvents such as benzene or benzine are to be determined, materials which absorb and dissolve in said solvent, such as plastics; polyvinyl alcohol, or nitrocellulose may be used for ethyl acetate vapour.  Known amounts of the mixture may be passed through the absorbent, or if only small quantities of the gas to be measured are present, the mixture may be passed at a known constant velocity until a measurable change in electrical properties is observable.  The temperature should be kept constant.  The absorbent, preferably retained in a non-conducting tube through which the gases are passed, may be arranged in the field of a coil or electrical condenser which is connected in an oscillating circuit: details of one embodiment are given.  One or more gas or vapour may if desired be removed before the determination of a particular component of the mixture, e.g. steam is desirably removed with dried calcium chloride before determining benzine by absorption with active carbon or silica gel.  Two or more zones of the same or different absorbing agents may be employed, each zone being separately arranged in an electromagnetic field thus permitting selective detection of the gases or vapours.  The process of the invention may be used to control continuously the composition of air in rooms or of gas in gas pipes.  The variations in the magnetic field may be, e.g. continuously registered or used to switch contacts on and off when predetermined values are exceeded.
