Title: Capillary viscometer
IPC: G01N11/06
Filed: 1971-01-19
Abstract: 1329202 Capillary viscometer CIBA-GEIGY A G 19 Jan 1971 [22 Jan 1970] 2679/71 Heading G1S A U tube having arms 1, 2 and a flared ended capillary tube 11 is immersed in a thermostatic bath B and is provided with a fixed measuring electrode 5, a micrometrically axially adjustable electrode 6, a reference electrode 10 and a micrometrically axially adjustable control electrode 9. The liquid to be tested is supplied through a pipe 3 and the viscometer has a measuring  control system which comprises a pipe 25 having valves 14-18 which connect it to the following parts: a flushing water pump 19, a suction pump 20 connected to a manometer 43 and a vacuum pressure water column gauge 21, a pressure pipe 36 connected to a manometer 34 and an adjustable pressure mechanism 22, 23. In operation a valve 14 is opened and a valve 15 closed and 20ml of the test liquid is supplied to the U tube through filler tube 3. A starter 28 is then operated which switches a change over relay 27 to cause valve 14 to close and 15 to open. The vacuum pump 20 monitored by the manometer 43 then sucks the liquid around the U tube until its meniscus touches the electrode 9. An electrical signal now appears in the circuit 9-90-31-100-10 and operates the relay 31 which operates relay 27 and causes valve 14 to open and valve 15 to close. At the,same time the clock 32 is zeroed. The electrode 9 has been adjusted by its micrometer screw 8 so that the upper meniscus will just touch 9 before the lower meniscus reaches electrode 10. The valve 14 in opening vents the U tube arm 1 and the liquid now rises in arm 2 and touches electrode 5 in the circuit 5-50-30-100-10 which activates relay 30 and starts the clock 32. Upon reaching electrode 6 a signal passes through circuit 6-60-30-100-10 to activate relay 30 again and stop the clock 32. The measured time is a function of the viscosity. The measurement can be repeated by operating the starter 28 or by employing a timer 29 and a recorder (not shown). For measuring thixotropic liquids the latter may be retained in the upper part of the arm by opening the cock 17 to adjust the vacuum, and adjustable pressure supplied through cock 16 permits measurements to be made under varying shear stress. In a prepared apparatus three such viscometers are immersed in the bath B and used in sequence.

Title: Improvements in and relating to hand-brake levers
IPC: G05G11/00
Filed: 1943-02-19
Abstract: 569,722. Locking levers. TRIGGS, W. W. (Caldwell, C. W.). Feb. 19, 1943, Nos. 2806/43 and 1486/44. [Class 80 (iii)] [Also in Groups XXXI and XXXIV] Hand brake mechanism suitable for motor cars, comprises two hand levers each movable about its lengthwise axis to control a detent for the levers and also about an axis perpendicular to its length to apply the brake, the levers being so connected that the movement of one is reproduced by the other. The detent comprises a member carried by one of the levers and adapted frictionally to grip a fixed rod when permitted to assume an inclined position relative to the rod. Two detent members may be provided one of which can be rendered independant of disengaging control by the lever, by a key-lock device. As shown, two hand levers arranged at either side of the driver of a motor car for the driver and a passenger respectively, each comprise a tubular part 11, 110 rotatable upon a part 10, 100 secured to a rock-shaft 15 connected to the brakes by members 18, 19. Relative endwise movement of the parts of the levers is prevented by a transverse pin secured at its ends to the tubular part and passing through a slot in the inner part. The parts 11, 110 are coupled for simultaneous movement about their lengthwise axis by arms 28 and rod 27. The detent device comprises a laterally-projecting arm 25 fixed to the lever part 11 and gapped at 26 to embrace arc-shaped rod 20 secured to the vehicle and to the shaft 15 at 21, 22, the centre of the arc being at the shaft axis. The lever parts 11, 110 are rotationally biassed by a torsioii spring rod 29 fixed at one end to the lever part 100 and extending into the cranked handle part 130, to cause the detent 25 normally to assume the inclined position shown in Fig. 3 so that the tendency to downward movement of either hand lever after the brake has been applied causes the detent to grip the rod 20. The detent may be disengaged by turning either lever part 11 or 110 about the part 10 or 100 respectively. To prevent release of the levers by manipulation thereof, when desired, an additional detent-32 is connected by a link 35 to the detent 25 and can either be held parallel to the detent 25 by a cranked pin 38, as shown, so that it is disengageable with the detent 25 by the rotational movement of the lever parts 11 or 110 or by removal of the pin 38 can be left free to grip the rod 20 by the action of a spring 36 irrespective of such movement of the lever parts. For this purpose, the pin 38 is secured to the rotatable barrel of a key-lock 40 carried by the lever 11 and it can be held in the position shown in Fig. 3 by engagement with projection 42 or be turned to and locked in an upper position by a removable key 44. The detents are rendered inaccessible by a casing 45.
