Title: Improvements in or relating to counting arrangements
IPC: H03K29/00
Filed: 1947-05-09
Abstract: 632,327. Counting-apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BAKER, G. T. May 9, 1947, No. 12543. [Class 106 (i)] A decade counting circuit comprising thermionic valve units operating on a scale other than denary, in which indication of the count is provided by applying potentials from the individual stages to the defection plates of a cathode-ray tube to cause the light spot on the screen to take up positions characteristic of the count. The face of a C.R.T. is provided with a series of digits 0 to 9, Fig. 1, e.g. by securing a sheet of suitable paper in position having the numbers on the reverse side facing the screen. By de-focussing the beam slightly a spot of light sufficient to illuminate the whole face of each digit is obtained. The C.R.T. is controlled from tappings at the anode loads of the valves of a counter built up from four binary stages represented by anodes AA, AB, AC, AD, AE, AF and AG, AH, Fig. 2. When the counter stands at zero, the lower halves of each stage are conducting while the upper halves are non-conducting and therefore the potentials at the tappings for plates PX2 and PY2 in the second and fourth stages are more positive than the potentials at the tappings for plates PX1 and PY1 in the first and third stages. This results in the deflection of the beam to illuminate the digit " 0 '' on the screen. The arrival of the first impulse at the counter unit reverses the first stage, causing the tapping for plate PX1 to become more positive. Thus the beam is shifted to illuminate the digit " 1 " on the screen. The tapping at the load YD for the plate PX2 is arranged so that the drop in potential when current flows through the anode AD is twice that for the plate PX1; thus, at the count of two, when the lower half of the first stage and the upper half of the second stage are conducting, the difference in potential between the plates PX1, PX2 deflects the beam to the " 2 " position. At the count of three the potential difference is further increased, bring- ing the beam to the " 3 " position. The fourth impulse reverses the third stage of the counter whereby the potentials on plates PY1, PY2 become equal, bringing the beam to the centre row of digits ... and so on. A biassing potential may be applied to the plate PX1 to make the frame of digits symmetrical with respect to a vertical centre line.

Filed: 1957-04-18
Abstract: 857,696. Photo-electric measurements. McCLELLAN, J. F. April 18, 1957, No. 12765/57. Class 40(3). The thickness and/or refractive index of glass is measured by scanning it with a beam of light and determining the displacement in cycle time of the light reflected from the article. Light from a source 24, is reflected by a rotating silvered prism 44 on to mirrors 58 and 18 to scan over a glass strip 12 to be measured. The reflected beam 66 and the refracted beam 70 pass consecutively through an aperture 80 to fall on a photo-cell 74, the pulses from which are fed in turn to an amplifier, a flip-flop circuit and a potentiometer, and the difference in time between the pulses displayed on a cathode-ray tube as a function of the refractive index or thickness. Measurement of the refractive index of a liquid in a transparent tube is described with reference to Fig. 13 (not shown). Other embodiments include the use of two photo-cells, one on each side of the glass, an arrangement in which the source of light is on one side of the glass and the cell on the other (Fig. 16, not shown), or scanning produced by movement of both the light source and the photo-cell (Fig. 17, not shown). The height of an opaque substance may be measured by using only the reflected beam and a reflecting surface defining one of the planes to be measured (Fig. 14, not shown). The output representing glass thickness can be used to control the glass making process.

Abstract: 883,018. Inertia switches. CITROEN S.A. ANDRE. April 15, 1959 [April 17, 1958], No. 12861/59. Class 38 (5). [Also in Group XXXIV] A switch actuated to disable brake applying means in response to a predetermined rate of deceleration of a vehicle wheel comprises a base-plate 20 and cover 21 bolted to the fixed part 27 of a bearing for axle 2 which carries the vehicle wheel on its other end. A shaft 1 is coupled to axle 2 by a slot 4 and pin 3, and a member 8 held in frictional engagement with disc 7 by a spring washer 9 is driven thereby. A screw 17 on a flywheel 5 is held by a spring 18 in engagement with a projection 8a on member 8. The flywheel 5 is otherwise freely rotatable on shaft 1 and carries an insulated contact 12 for engagement with a contact 11 on member 8. Rotation of shaft 2 counterclockwise (Fig. 3) thus drives member 8 and flywheel 5, electrical connection to contact 12 being maintained by means of a blade 16 engaging a stud 22 wired to terminal 23 in cover 21. If the drive decelerates above the predetermined rate the inertia of flywheel 5 causes it to move relative to member 8, stressing spring 18 and closing contacts 11, 12, since the friction between member 8 and disc 7 is greater than the torque due to spring 18. The impact of contact 12 on contact 11 is, however, reduced by frictional slip and rebound off the contacts is prevented. Specification 883,019 is referred to.
