Patent GB-567195-A (GB)
Title: An automatic electrical integrating and averaging device for a variable medium
IPC: G06G7/188
Filed: 1943-08-31
Abstract: 567,195. Telemetering. SIGMA INSTRUMENT CO., Ltd., LOXHAM, J., and BOOSEY, F. R. Aug. 31, 1943, No. 14221. Addition to 557,782. [Class 40 (i)] [Also in Group XXXVI] In the automatic integrator claimed in the parent Specification, the driving electromagnet coils are each made up of two exactly equal windings C, D and E, F connected with differential control resistances R1, R2 so that one winding opposes the magnetomotive force of the other. Rotation of the disc RO is transmitted by gearing to counters H, G registering revolutions in opposite directions. The brake magnet BM may be an electromagnet connected to the same source of supply as the driving magnets M1, M2. Assuming that it is desired to measure the amount by which the calorific value of a given quantity of gas differs from the required value, the contact A of the resistance R1 is connected to the pen mechanism of a calorimeter so that it is in its central position when the calorific value is normal. The coils C, D then neutralize one another and no flux is produced by the magnet M1. The contact B of the resistance R2 is connected to a flow gauge and is in its central position for zero flow. The disc RO rotates at a speed proportional to the product of the factors. The counters may be provided with shutters which obscure the reading when the counter is running backwards and passes through zero. Switches J are arranged so that they close only when the counters indicate zero, the numeral discs being profiled to permit this. The switches are all connected in series so that any one disc moving off zero breaks the circuit. They are connected in circuit with associated apparatus such as an automatic proportioning device which should be temporarily inoperative when the integration is off zero. One or more further coils may be added on either of the driving magnets to give the algebraic summation of a plurality of variables as well as the product of the resultant with other variables. Specification 549,249, [Group XXXV], is referred to.

Filed: 1974-04-04
Abstract: 1429406 Friction and wear tests E KUSS 4 April 1974 [18 April 1973] 14945/74 Heading G1S A method of carrying out a friction and wear test or a test of oil lubricating properties comprises a closed high-pressure autoclave 16 which may be filled with oil when a compressor 14 and a valve 15 are operated. At the same time, a valve 18 is operated so that the interior of an hydraulic cylinder 21 is put under the same pressure. The valve 15 is then closed and the piston in cylinder 21 operated by continued flow through valve 18 to exert a compressive force on four balls 20, the top one of which is driven by an electric motor 25 through a clutch 26 and a driving-shaft 27. Inside the autoclave 16 is a measuring device comprising radially grooved disks 4 co-operating with electromagnetic pick-up heads 3 and a load cell 24 so that torque transmitted, load, r.p.m. and so on may be plotted against wear or indentation dk of the balls Fig. 6 (not shown). The signals 40', 41' Fig. 5 coming from the heads 3 are amplified and converted into rectangular pulses 42', 43' in Schmitt triggers 42, 43. After differentiating, needle pulses 44', 45' are obtained and filtered to give positive pulses 46, 47 which are passed to a bi-stable multivibrator 48 which gives rectangular pulses 49 of a length corresponding to the phase displacement between the signals of the pick-up coils. The mean value of this phase displacement with respect to time Im is indicated and gives a direct measure of the torque transmitted. In Fig. 3 test fluid being tested is charged into the removable ball carrier through a bore 11 to the space between the balls, and the ball carrier is suspended by two pins 12 which absorb the reaction moment. In a four ball test under pressure the driving motor is switched off by a thyristor control unit when the balls become welded together and the clutch is simultaneously disconnected. The separation of the test substance from the pressure medium which is oil is effected by shaft sealing rings 7, a hose type diaphragm 9 and the O ring 10. Figs. 7a, 7b (not shown) illustrate the mounting of non-friction bearings and planetary gears for test.
