Patent GB-486446-A (GB)
Title: Improvements in or relating to indicating and/or recording and/or controlling apparatus
Filed: 1936-12-02
Abstract: 486,446. Electric signalling systems. KENT, Ltd., G., and KENT, W. R. L. Dec. 2, 1936, No. 33095. [Class 40 (i)] [Also in Group XXXV] In a system in which the outputs of a number of thermo-couples are measured and recorded in turn by automatically adjusting the tapping point of a potentiometer to balance a bridge circuit, the potential drop in the potentiometer is periodically automatically checked by connecting a standard cell to the circuit, and the bridge circuit conditions are automatically adjusted if necessary. The circuit is normally connected as shewn in Fig. 8, a wiper connecting one of the thermo-couples T in series with the galvanometer 11 across a potentiometer to compare the e.m.f. developed by the thermocouple with that developed across the potentiometer by battery B. The galvanometer takes up a position corresponding to the ratio of the e.m.fs. The pointer 10 of the galvanometer is periodically clamped between plates 9 and 12 and arms 17, 18 are swung together until arrested by the pointer. If the pointer is not central arm 25 is tilted and is then reset by cams 26, the resistance wire 29<1> being moved relative to wiper 29<2> during the resetting motion of the arm and the recording carriage 35 being moved along the shaft 36. After the adjustment has been made a number of times the carriage 35 is lowered to allow a face of drum 37 to make a record on the chart 8. The wiper is then moved to connect another thermocouple to the circuit and the shaft 36 is turned to bring the recording face of drum 37 relative to the new position of the wiper above the chart and the process is repeated. In one position whilst the wiper is moving from one set of contacts 4 to the next, contact arms 79, 81 change over, so that the connections of switch 3 are replaced by standard cell C and resistance wire 68 is coupled to resistance wire 29<1>. If the battery B is working normally the pointer 10 of the galvanometer 11 takes up a mid position and when the pointer is clamped the arm 25 is not tilted. If the circuit conditions have changed however the galvanometer deflects, arm 25 is tilted and restored as described above and resistance wire 68 is moved relative to the tap 69 to re-adjust the voltage drop in the potentiometer 29<1>. The contact arms 79, 81 then remake their normal contacts and cyclic recording continues. The potentiometer tapping 29<2> is adjusted with the resistance 68 and if the recording has not taken place this ensures a correct recording of the previous reading. If the testing is effected after recording has taken place contacts 87, 90, 91 are provided. These contacts are operated if the potentiometer tap 29<2> is in a limit position when testing is about to take place. The contacts shunt galvanometer 11 by resistance 74 so that the potentiometer tap moves to an intermediate position and so allows the shaft to which both wires 29<1> and 68 are clutched during testing, to be moved in either direction if necessary.

Title: Improved means for use in examining the contours of gear wheel teeth
IPC: G01B5/20
Filed: 1931-11-30
Abstract: 385,411. Gauging toothed gears. GEAR GRINDING CO., Ltd. and SNARRY, J. W., Anne Road, Handsworth, Birming- ham. Nov. 30, 1931, No. 33097. [Class 106 (ii).] The gear b is coaxially secured to a circular fixed body a while a member e rotatable about the axis of the fixed body carries slidably mounted on it a part g on which in turn is mounted a slide h adapted to move at rightangles to the slide g and carrying a feeler j adapted to engage the gear teeth. A flexible band k is secured at one end to the body and after being wrapped partly around it is secured to a rack-bar l which engages a pinion m which is constantly acted upon by a torque supplied by a weight or spring. The bar is carried on the end of the part e between rollers n, n and the strap k. The part e, an extension o of the slide h and the rack-bar l or the strap are connected together by a link p. The latter is pivoted at the point r to the part e and is connected to the extension o by passing between rollers t in a part s pivoted to the extension. The link p also passes between rollers in a part u pivoted to the rack-bar. In use the gear to be tested is mounted on the spindle d and the slide g moved to bring the part s to a suitable position on the link p. The distance of the parts u, s from the pivot r are then in the ratio of the diameter of the body a to the diameter of the pitch circle of the gear b. The feeler j is also brought into engagement with one side of the tooth to be tested. The member e and connected parts are rotated as one piece about the body a. The feeler will traverse the face of the tooth which if correct will not cause the other end of the feeler to give an indication on the scale or to actuate a dial gauge.

Abstract: 339,079. Dias, J. A. Nov. 5, 1929. Centrifugal speed-indicators; with indicating- and signalling apparatus and means for controlling motors; particular speed alarms. - In a means for retaining the speed of a motor vehicle within a fixed maximum, a centrifugal governor is driven through a shaft Z and carries a disc T, the movements of which are transmitted to a lever S. The quadrant C is attached to the same pivot as the lever S and gears with a pinion B carried by the disc A. The disc A carries a contact bar E which, when the speed limit is reached, contacts with pins H and G and illuminates a lamp P and gives audible alarm on the horn Q.

[Also in Group VI] In pressing liquid out of, e.g., a vegetable substance during its passage through press chambers provided between a spindle with flights and a surrounding perforate screen wall, the chambers being separated by intermediate resistors, the press is characterized in that the numerical quantity Q obtained by multiplying the volume of the first press chamber by the number of flights in the chamber and dividing by the screen area of the chamber is at least four times as great as the corresponding numerical quantity for the last chamber, and furthermore the ratio of these quantities for the first two chambers is greater than the corresponding ratio for the last two chambers. Moist material, e.g., beet pulp, is fed by a worm 16, Fig. 1, into a hopper 12 where it is stirred by members 11 on an extension 10 of a screw spindle 1 prior to passing into the space between the spindle and a cylindrical screen jacket 3. The space is partially divided into four press chambers, P1.. P4, by resistors in the form of short guide plates 8 extending between sets of screw blades S 1  . . S 4 . The space between the screen jacket 3 and an outer casing 4 is divided by partitions 2 into three compartments each having a juice outlet 5, 6 or 7. The pulp is discharged through openings 26, Fig. 1, in a rotatable valve disc 24, Fig. 3, and thence through corresponding openings 27 in a supporting disc 23. By adjustment of the valve the pressure in the final press chamber P4 may be made to exceed 2.5 atmospheres. In Fig. 6 six press chambers are provided, of progressivelydiminishing height, and there are two screw blades on the spindle 1 in each chamber. The volume of each chamber is represented as a hatched rectangle in Fig. 7 and the ratio V/A as a horizontal distance from the vertical axis through the figure 0. In Fig. 8 (not shown) there are eight press chambers all the same height with two screw blades in each of chambers P2 and P3 and four in each of the remainder; the spindle is cylindrical in chamber P1 and in most of chamber P2, and there is an abrupt change of cone angle in chamber P4. The quantity Q for the first press chamber is preferably at least twice as great as that for the second press chamber and at least three times as great as that for the third press chamber. The ratio between the quantities Q for any two successive chambers is preferably greater than the ratio between the corresponding quantities for any two subsequent and successive chambers. The spindle may be perforated and used for drainage. Specification 803,216 is referred to.
