Filed: 1957-03-01
Abstract: 808,794. Conductivity cells. LEEDS & NORTHRUP CO. March 1, 1957 [March 2, 1956], No. 6946/57. Class 37. A conductivity cell consists of a moulded casing 11 with passages 15 and 16, open at the lower end and connected at the upper end by a transverse passage 12 which extends right through the casing. The electrodes 17 and 18 and their leads are embedded in the casing. The leads 13 and 14 protrude through the top of the casing to form pin connections. The design of the cell ensures that only the inner surfaces of the electrodes are exposed to the fluids and hence only the electrodes need be of resistant material such as platinum or graphite. The leads are wholly enclosed in the casing. As shown in Fig. 2, the casing may be threaded at the top 11a, to enable a manipulating means 20 to be screwed on and it mav be threaded at the bottom 11b, to receive a coupling member. The transverse passage 12 may be used as a toolreceiving cavity for rotating the cell. It may also be used as shown in Fig. 2 for attaching a pump to draw liquid through the cell. The electrodes are preferably placed so that the resistances of the two conductive paths (one through 12 and the other via the open ends 15a and 16a of 15 and 16) are equal. A fluoro-carbon resin is a suitable plastic from which the cell may be moulded.

Filed: 1955-03-10
Abstract: 784,095. Magnetic recording and reproducing apparatus. ENGLISH ELECTRIC CO., Ltd. March 8, 1956 [March 10, 1955], No. 7116/55. Class 40 (2). In a closed loop position control servomechanism arranged to control the relative position of a magnetic transducer bead with regard to the record medium, a lever affording a mechanical advantage serves to increase the sensitivity of a mechanical/electrical translation by which an electrical measure of the position of a controlled member is obtained. In the embodiment described, a record cylinder 10 carrying multiple tracks is recorded upon and/or reproduced by a number of transducer heads 12a carried by a unit 12 which may be axially displaced to a number of different positions whereby a number of tracks corresponding to the product of the number of heads and the number of tracks recorded by each may be recorded or reproduced. A signal received by a unit 20 from an electrical system 28 causes the axial position of the unit 12 to be varied from a neutral position determined by a spring 23 acting through the medium of a lever 16 against the gravitational effect of the unit 12. The longer arm of the lever 16 carries the wiper contacts 25 of a potentiometer connected such that greater sensitivity of the mechanical/elec. trical translation is effected. Fig. 2 shows the method whereby a fine adjustment of the axial rotation of unit 12 is obtained by means of an eccentrically mounted pin 47 which is adjusted manually by means of a knurled ring 48 and acts on a forked arm 46 mounted on the spindle 31 carrying the unit 12. In this embodiment the potentiometer lever is coupled by a flexible leaf spring 42. Figs. 3a and 3b (not shown) illustrate coupling means employing ball races to eliminate friction and backlash. Specification 775,101 is referred to.
