Patent GB-863510-A (GB)
Title: An improved viscometer
Inventor: SAW PETER DOREE
IPC: G01N11/12
Filed: 1958-05-14
Abstract: 863,510. Viscometers. TYER & CO. Ltd. May 14, 1959 [May 14, 1958], No. 15431/58. Class 40 (1). [Also in Groups XIX, XXXVI and XL (c)] In a viscometer which is based on the time of fall of an object between two spaced points in a tube containing the liquid under test, the object changes the frequency of an oscillator as it passes one of the points, and the time of fall is determined electronically from these changes of frequency. In Fig. 4 the liquid is contained in a tube 6 mounted in a jacket through which steam or water can flow via 24 and 25. Around the tube are coils 35 and 36 which suffer a momentary change in inductance due to the passage of the object, which is a metal sphere (e.g. of phosphor bronze) or is coated with a metal such as copper. The coils are joined in series and shunted by a capacitor, and are connected via a twin coaxial cable to a Colpitts oscillator V1 (Fig. 5). The output of the latter goes to a phase discriminator V2 which delivers a pulse each time the object passes one of the coils. The pulses are amplified in V3 and trigger a bi-stable multivibrator V4 to produce a square wave on the grids of a further multivibrator V6. The first pulse allows V7 to conduct and energizes a relay 37 which joins the grid of a time-base valve V11 to the positive supply. The meter reading of the valve voltmeter V12 then starts to rise. The second pulse from V2 switches V6 back to its original condition and cuts-off relay 37 so that the grid potential of V11 ceases to rise and the meter reading remains steady. At the same time a mono-stable multivibrator V9 is triggered so that after a few seconds relay 38 is energized to restore V11 and the meter reading to their original states. If two spheres should be dropped in simultaneously the pulses will overlap, V6 will not be switched back to normal and the meter reading will rise above full-scale. At this point, however, the screen potential of V11 falls and triggers V10 to send a pulse back to V6 to change it over. A neon 39 indicates correct operation of V3 and V4. The sensing coils in the tubes can be replaced by capacitors.

Title: Improvements in or relating to the method of, and means for, controlling mechanically propelled vehicles
IPC: B60K23/02
Filed: 1924-06-27
Abstract: 240,522. Brown, C. June 27, 1924. Controlling different functions by same lever; interlocking; pneumatic transmission; power apparatus.-When the driver closes the throttle the clutch is automatically disengaged by (a) power derived from the engine, or (b) electric, pneumatic or like connections between the throttle and clutch mechanisms. The clutch is engaged again when either the throttle control or the brake lever is actuated. A valve chamber a is connected by a pipe f to the induction pipe f<2> of the engine and by a pipe g to a cylinder h adapted to disengage the clutch. The chamber a contains two sliding valves c, d normally pressed apart by a spring e against stops c<1>, d<1>. When the accelerator pedal j<2> is released and goes back to the idling position it acts on the valve c through linkage j<1> and puts the pipe f into communication with the pipe g so that a partial vacuum is created in the cylinder h and the clutch is disengaged. If the brake pedal l<2> is now depressed it pushes in the valve d closing the port g<1> which has been in communication with the pipe f and opens the pipe g to the atmosphere through ports g<2>, d<x> so allowing the clutch to become engaged again by its spring i<3>. If the accelerator pedal is depressed instead of the brake pedal, the valve c is released and takes up the position shown in Fig. 1 in which the pipe f is closed and the pipe g is open to the atmosphere through ports g<1>, k. A lost motion connection may be provided between the clutch pedal i and the piston in the cylinder h. The interconnection of the controlling means may be effected electrically or by pressure fluid. According to the Provisional Specification a single valve is used.

Abstract: 460,692. Variable speed gearing. KETTEN UND GETRIEBE GES., P. I. V. June 3, 1936, No. 15494. Convention date, June 3, 1935. [Class 80 (ii)] A continuously variable change-speed gear comprises a driving-shaft 2 connected to a planet carrier 45 of a differential gear, the sun wheels 47 and 48 of which drive shafts 51 and 55 respectively in the same direction of rotation. The relative speed of these two shafts is controlled by a continuously variable regulating device in the form of expanding conical pulleys 80, 81 and a belt 82. The speeds of the two shafts 51 and 55 are combined by means of another differential gear, the suns 58, 59 being geared to the shafts 51, 55 and the planet carrier 60<1> being connected to a driven shaft 27. When the speeds of the shafts 51 and 55 are equal the speed of the driven shaft 27 is zero, and by varying the relative speeds of the shafts the speed of the shaft 27 can be varied in both directions of rotation. In a modification spur gearing is employed for the differentials instead of the bevel gearing shown.
