Title: Improved automatic mechanical hysteresis correctors for pressure gauges influenced by the characteristics of a medium or adapted to measure these characteristics
IPC: G01L13/02
Filed: 1936-08-14
Abstract: 472,565. Pressure-gauges. ETABLISSEMENTS E. JAEGER. Aug. 14, 1936, No. 22481. Convention date, April 14. [Class 106 (ii)] An automatic mechanical hysteresis corrector for diaphragm and Bourdon gauges comprises the combination with at least one body deformable under the pressure of a medium of at least one enclosure having deformable walls included in the movement transmitting mechanism and in which is stored a fluid, this enclosure communicating, by a pipe having a predetermined calibrated outflow section, with a reservoir which may be the atmosphere. In the altimeter shown in Fig. 1, the main box 1 is connected to a support 2 and communicates its movements to a needle 4 by a gearing up system 5. The correcting box 6 with outflow opening 7 is interposed between the main box 1 and the gearing. As the instrument installed'on a plane rises, the box 6 is distorted under the air it contains, but the air escapes at such a rate that compensation is effected for hysteresis lag in the main box. Several forms are described in which the compensating box is mounted below, or immediately on the top of the main box having a common wall therewith, or in one link of the transmission mechanism. In another form for a pressure gauge, the pressure is admitted to the interior of the box and the movement of the common wall affects the pressure in the compensating box. In the form shown in Fig. 6, the compensator is formed by a rigid bowl 10 to the top of which is secured a diaphragm 11 carrying a fork 12, the leakage taking place through a flattened tube 7. Abutments 15, 16 limit movement of the diaphragm in each direction. In Fig. 8, a tube 1K and a compensating tube 6K having a leak 7 are shown. Instead of the tube 6K, a capsule with a leak may be fitted. A tube with a leak may be fitted in the transmission mechanism from an aneroid box. The box may be filled with a liquid other than air when the compensating box will open into a tank containing a reserve of the fluid.

Abstract: 733,930. Tractor power take-off mechanism. HANNOVERSCHE MASCHINEN BAU AKT.-GES. VORM G. EGESTORFF, HANOMAG. Sept. 9, 1952 [Oct. 17, 1951], No. 22583/52. Classes 79(2) and 79(5). A wheeled or track laying tractor or the like has an internal combustion engine M and a change speed gear S between the engine and driving wheels 8, the engine being adapted to operate in two different speed ranges, means being provided so that the upper speed range can only be used to rotate the driving wheels when an additional reduction gear U, positioned between the engine and the change speed unit, is engaged, the engine having power take-off means for driving auxiliary appliances such as agricultural implements so that when it is operating in its upper speed range it can drive both the tractor and the auxiliary apparatus. The power take-off means may consist of one or more shafts 7 which are driven through a change speed gear box Z and gearing 5, 6 from the output or the input sides of the vehicle clutch K. The means for preventing the upper speed range being used when the additional reduction gear is not in use consists of an interlock (not shown) between a governor (not shown) and the additional reduction gear. The governor is adapted to limit the engine speed to two maximum speeds, one for each range.

Filed: 1920-07-29
Abstract: 150,994. Candlot, C. Sept. 10, 1919, [Convention date]. Discharging lime or like kilns. The bottom 5 supporting the material is fitted with lanceshaped radial teeth 17, and is rigidly fixed to a shaft 6, eccentrically mounted in the pivot 7, the axis of which coincides with the axis of the kiln.

A suspension of, e.g., calcium carbonate, infusorial earth, shredded cellulose or potato starch is discharged along a pipe 10 from a vat 13 by a pump 15 to a V-shaped chamber 9, Fig. 2, constituted by a fixed plate 7 and a plate 8 slidable so as to vary the gap between them. The suspension falls on to a cylinder 6 rotating counter-clockwise and preferably having a non-smooth surface, and is projected thereby on to the drum 1 in the form of jets or sheets. The cylinder 6 is mounted on a support 21 which also carries a knife 16 and circular brushes 17 and is movable by a motor-operated screw 22 to vary the depth of cut and the amount of filter aid deposited. Excess suspension is collected at 11 and returned at 12 to the vat 13, Fig. 1. A roller 18 on slide tracks 19 equalises and compresses the filter aid layer. The brushes may be replaced by one or more endless chains carrying scrapers. In Fig. 2A (not shown), the cylinder 6 rotates clockwise, and the plate 7 occupies approximately the position formerly occupied by plate 8 (which is now dispensed with) and carries a vertical overflow weir behind which the suspension is fed from under a downwardly-depending baffle by the pipe 10.

Title: Improvements in electrical communication switching systems

IPC: H04J3/00
Filed: 1949-09-06
Abstract: 716,171. Automatic exchange systems. POSTMASTER GENERAL. Aug. 21, 1950 [Sept. 6, 1949], No. 23081/49. Class 40 (4) [Also in Group XL (c)] In a multiplex telecommunication exchange system of the type described in Specification 694,092, in which a line-finder or selector is required to produce pulses at a position in a time cycle determined by a single input pulse, a condenser-resistance discharge circuit is used to time the production of the pulses. These pulses are required for suppressing "calling" pulses once a calling pulse has seized an idle finder-selector link and also for gating pulses in the time positions of the called and calling subscribers into the finder/selector link. The arrangement shown in Fig. 4 is utilized for selecting a pulse channel from amongst 100 such channels the time position of the required channel being determined by that of a single initial pulse on the calling lead 11. The input to lead 13 consists of pulses occupying the time positions of all 100 channels one of which coincides with that on 11 and commences immediately after the reception of the first, and only, pulse over lead 11. The timing circuit comprises three triggered blocking oscillators V2 V3, V4. The first is initially triggered by the pulse on lead 11 and restores to normal in time to be triggered,again by the fourth pulse after this applied over lead 13. Thus every fourth pulse produces an output pulse from V2 which is caused to trigger V3. The period of the latter is such that it restores to be retriggered every fifth pulse it receives. The output from V3 triggers V4 which also produces an output pulse for every fifth pulse it receives. The times of restoration are controlled by the resistance-capacity circuits C4, R9, 10; C15, R13, 14 ; and C16, R35, 36. While C4 is discharging D11 is cut off and W11 feeds current to lead L to cause W71 to conduct and W81 to be cut off. Similar currents are fed from W21, W31. When however all three condensers are discharged simultaneously W11, 21, 31, are cut off so permitting one of the pulses I to cut off W71 and pass through W81 to valve V5. The pulses I are somewhat earlier than those fed to circuit 13 and are fed via V5 to the triggered blocking oscillator V6 whose output is controlled by the delay, line DL and is taken away to suppress the calling line pulses as previously described. When the selector is not in use rectifier W41 is conducting thereby cutting off W81 to prevent pulses I being fed to the pulse suppression lead. On seizure of the selector and the consequent triggering of V3 the output pulse rectified by W61 charges condenser C8 to block W41.
