Title: Improved method and apparatus for testing the viscosity of a liquid
Inventor: BRUYNE NORMAN ADRIAN DE
IPC: G01N11/06
Filed: 1959-05-11
Abstract: 894,749. Viscometers. TECHNE (CAMBRIDGE) Ltd. May 10, 1960 [May 11, 1959], No. 16087/59. Class 106 (2). Apparatus for measuring the viscosity of a liquid comprises a piston or liquid column compelled to move so that it compresses and maintains at constant pressure gas acting on the surface of a liquid in a container, the liquid being forced through a restriction or capillary and its viscosity measured by the time taken for a given volume to pass therethrough. As shown, gas in tubes 7, 5 acts on liquid in a container 1 and forces it through a capillary tube 2. Consequential fall in the gas pressure allows mercury column 9 in manometer 8 to break contact with an oscillating contact 23 thus de-energizing a relay 18, releasing brake 17 and allowing shaft 42 to rotate and a piston 13 to drop further into a cylinder 10 until the lost volume of liquid is compensated for and the column 9 again contacts the contact 23. Thus the pressure of the gas is maintained at a constant value. The operation is started by closing mains switch 52 to energize a pump 11. A lever 27 is raised to open a solenoid operated valve 26 and to lift a platform 29 carrying a microswitch and time delay switch. The valve 26 is closed by lowering lever 27 and ensuing rotation of shaft 42 to lower piston 13 causes a quadrant 41 to engage switch 43 energizing a time recorder 44 and moves a lever 38 to release platform 29, thus actuating microswitch 33 and providing a pulse through printer 35 which may be connected to time recorder 44. A container which is immersed in the liquid and closed by a valve 45 operated by air pressure may replace the container 1.

Title: Improvements in photoelectric register control systems
IPC: B65H23/188
Filed: 1940-11-18
Abstract: 544,084. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 18, 1940, No. 16603. Convention date, Nov. 17, 1939. [Class 38 (iv)] [Also in Group XL] Registration between an element operating on a length of material and indicia on the moving material is effected by means including an electric valve requiring simultaneous variation of the voltage of two control members to vary its conductivity. These voltages are supplied by impulses derived from photoelectric devices responsive respectively to light changes due to the passage of indicia on the web and to the motion of the element registered. A motor 15 drives rolls 11  feeding paper printed with postage stamps and, through a differential gear 16, perforating rolls 13 and sheet severing means 14. The two latter are maintained in register with indicia 34 at frequent intervals on the paper by speed changes of a motor 19 having its armature energized by a generator 21 driven by the motor 15. The generator field is normally energized so that the element 16a of the differential gear is driven at half speed. The generator field winding 21a is energized by the output current of vacuum valves 23 ... 25 in parallel. The grid voltage of these valves is determined by the output current of an amplifier 31 the grid potential of which varies with the charge on series connected shunted condensers 47, 48 the first of which is large and has a large time constant and the second small and with a small time constant. Impulses of a polarity determined by the sense of error in registration are supplied to the condensers through rectifiers 73, 79. Mixing valves 44, 45 pass current impulses when the perforator rods are slow and fast respectively the impulses from the valve 44 being inverted by a valve 68 for transmission to the condensers 47, 48. The mixing valves each have two control grids whereby they pass current only when both receive voltage. One grid of each is energized each time an index mark passes a photo-electric device 32b, causing a momentary fall in current through a valve 33. A slotted disc 40 driven by the perforating rolls passes light through slot 36a or 37a if these rolls are slow or fast respectively whereupon a photoelectric cell 36 or 37 causes reductions of current in a valve 38 or 39 to energize the second grid of mixing valve 44 or 45 in proportion to the register error at the same time as its first grid is energized by the impulse from valve 33. The low time constant of condenser 48 results in a rapid but short change in generator field current and corresponding correction of registration and the high time constant of the condenser 47 causes a slow follow-up change in correction, thus avoiding heating.
