Title: Improvements in or relating to speed measuring apparatus
Inventor: AGAR WILLIAM OLIVER
IPC: G01P3/80
Filed: 1964-08-05
Abstract: 1,123,950. Measuring speed photo-electrically. MARCONI CO. Ltd. July 12, 1965 [Aug. 5, 1967], No. 46911/67. Divided out of 1,118, 879. Heading G1A. The invention relates to the photo-electric determination of the relative speed between a member and a reference point. The member may be a moving steel strip emerging from a rolling mill, the speed being measured relative to a fixed reference point. If the member is a road, the reference point is a moving vehicle the speed of which is to be measured. In the measurement of steel strip velocity, two single spaced lines 9, 9' are projected on to the strip 1 and the reflected light received through lenses 11, 11' by photo-cells 12, 12'. The output of cell 12 is delayed by a fixed amount and the two outputs fed to a differential circuit 14. The distance between the projected lines is adjusted until the difference signal is zero and the setting of the adjustment means 10 gives an indication of the speed. If instead of single lines, two similar patterns, spaced apart, are projected on to the strip, the photo-cell output contains a component dependent on strip velocity. If the strip is hot and lightemitting or receives general illumination, the projector 8 can be dispensed with the reflected light focused through grids or slits on to the cells 12, 12'.

Abstract: 1,130,870. Eddy current flaw testing. NATIONAL RESEARCH DEVELOPMENT CORP. Oct. 17, 1967 [Oct. 20, 1966], No.46955/66. Heading G1N. In eddy-current flaw testing apparatus it is found by plotting the inphase and quadrature components of the probe signal for different spacings of the probe from the sample, that the points lie on a curve, as illustrated in Fig. 2. Thus, if the probe signal is measured in effect from the center of this curve, (as by injecting a suitable vector signal in series) the amplitude will be substantially independent of the probe spacing from the sample in the absence of a flaw. The vector signal may by obtained from a transformer fed through a resistor and having its primary shunted by a resistor. The transformer may be fed in parallel with the probe Fig. 7 (not shown) or in series with the probe Fig. 3 (not shown). Fig. 3 also gives a detailed circuit of a transistor oscillator and emitter follower providing the probe supply and a transistor amplifier for the meter circuit.

Abstract: 1372080 Computer system; form reader TRW DATA SYSTEMS Inc 13 Oct 1971 [11 Jan 1971] 47697/71 Headings G4A and G4M A computer system calculates and records the value of sales transactions on an input/output form bearing clock lines and corresponding rows of data indicating the number of corresponding items sold and includes a computer and a form reader and printer controlled by the computer. The form is fed through the reader which senses the clock lines and scans the corresponding data which is fed to the computer and identified therein by a count of the clock lines. On sensing a data item the form is stopped and the cost of the items sold is calculated. When a form has been read the total cost of sold items is printed on the form by the printer. The Specification contains a detailed description, with reference to flow drawings, of the procedures adopted in the computer which has an associated drum store containing price data for the various items. Multiplication is performed by repeated addition, running totals being stored on the drum. The various procedures used are initiated in response to a count of the clock lines thus obviating the need for a controlling program. The form reader comprises a light-tight housing having windows 51, input light guides 53 and output light guides 54. The reader advances a form past the windows so that light from an input guide will, in the presence of a suitable mark on the form, be diffused through the form from the input to the corresponding output guide. The arrangement allows satisfactory reading without requiring accurate registration between the form and reader. The light guides may be optical fibres. The form 57 is advanced by a wheel 58 between a guide 55 having a slot adjacent the windows and spring clips 56 which serve to hold the form in position. The form includes a series of clock lines defining spaces in which data may be marked, e.g. by a waitress in a restaurant. Two other forms are described for entering data into the computer and for reading data out of the computer. These latter forms contain address data relating to the computer store.

[Also in Division G1] In the drying of a material the surrounding atmosphere is adjusted so that the ratio of the moisture content in the material and the equilibrium moisture content is constant by measuring the moisture content of the material and of a thin sample of the material, the latter result giving the equilibrium moisture content, and using these values to adjust the atmosphere. In the embodiment described amplifiers 1, 2, 3 measure the resistance between electrodes inserted into a piece of wood which is being dried to give an indication of the average moisture content at 4. The moisture content of a sample which is thin enough to be in equilibrium with its surroundings is measured by amplifier 8 giving an indication at 9. The value recorded at 4 is divided by potentiometer 5 to give a signal corresponding to the desired equilibrium moisture content and this is compared with the actual value by comparator 7 which has an output C which is used to control the drying conditions. When the moisture content reaches its desired value a signal is produced at 4 which activates a switch 6 so that the equilibrium moisture content is made to correspond to a conditioning value set on potentiometer 10.
