The corner members 7 have a sloping edge and/or a groove so that the clips 8 when turned from a position parallel with the front of the drawer, will slide over the edge and into the groove so as to press down. on to the sheets 11. The markers 12 are formed from a paper or cloth sheet with a tapered middle portion which when folded forms the finger 13, one side being provided with adhesive for attachment to both sides of the sheet 11. For positioning the marker 12 in relation to the scale 6, which may comprise several parallel series of letters or digits, the sheets 11 may have an outer margin with a broad front portion on which a similar scale 6 is printed, the margin and scale 6 being cut away after a mark has been made on the main portion of the sheet 11 to indicate where the marker 12 is to be fixed. Different colours may be used for the different series on the scale 6 with correspondingly coloured markers 12.

Abstract: 1311562 Securing cams to shafts ASSOCIATED ENG Ltd 12 June 1970 [27 June 1969] 28477/70 Heading F2U [Also in Division F1] A device for moving a cam relative to its driving shaft in particular to vary the control of the valves of an I.C. engine comprises cams 15, 18, 19 freely rotatable about a shaft 5. As shown for the cam 15 operating a valve 17 the phase of the cam can be varied by a drive which consists of a collar 8 rotated by the shaft driving by a pin 8a in a radial groove 10 a disc 9 which by a hole 12 is rotatable about the shaft but movable relative thereto and which in turn by a pin 15a in a radial groove 11 spaced from the groove 10 drives the cam 15. Movement of an arm 13 in the plane of the drawing as indicated at y produces eccentricity in the disc 9 relative to the shaft 5 and thus increases the speed of cam operation in one half cycle and decreases it in the other. Similarly movement of the arm 13 can be in a plane perpendicular to the drawing. In a modification, Fig. 4, not shown the bearings mounting the collar 8 and disc 9 are varied.

Title: A method and apparatus for weighing an oscillating load
IPC: G01G19/18
Filed: 1960-08-17
Abstract: 959,569. Measuring weight electrically. N. T. KARLEN. Aug.17, 1960 [April 14, 1960], No.28507/60. Heading G1N. [Also in Division G4] In order to weight an oscillating load, pulses are produced at a frequency dependent on the weight and are counted over a time period which includes at least one full oscillation of the load. In weighing the load in a crane scoop 163, strain gauges 165 contribute resistances 61, 63 to a bridge circuit 60-64 the output of which is fed, in opposition to the output of a tacho-generator 23, to an amplifier 12. The output of the amplifer 12 drives a servomotor 16 which drives the tachogenerator 23 and a disc 168 the latter producing intermittent illumination of a photo-transistor 171. Pulses from the photo-transistor 171 are counted in a counter 172 during the period of time between the instants when another counter 184 starts counting pulses from a generator 183 and when this counter 184 reaches its full capacity. Counter 184 starts counting when a switch 187 is closed. The count in counter 172 is indicated by lamps at 173. A potentiometer 64 is provided for adjustment so that an unloaded scoop 163 produces zero bridge output. To eliminate starting errors of the motor 16 due to its inertia, a bridge arrangement 189-196 is provided between the output of bridge 60-64 and amplifier 12 to introduce, before weighing commences, an extra voltage about equal to that which will be produced by bridge 60-64 during weighing. This extra voltage can be adjusted manually (by 193) by altering resistors 190, 192 as shown, or alternatively by adjusting a potential divider in the diagonal of the bridge 189-196. If the motor 16 is only to be started just before weighing, a time delay relay 200 is provided which on actuation of switch 195 prevents actuation of the counting means for a predetermined period. If the load is wet some may stick to scoop 163, and in this case to obtain the weight actually released from scoop 163, the scoop 163 is weighed loaded and unloaded (i.e. after dumping its load). two switches 197 actuated by the crane cable 164 being provided to ensure that the counter 172 counts up and down on receiving pulses corresponding to the weight of the loaded and unloaded scoops 163 respectively. The starting switch (187 or &c.) may only produce an effect when the motor hauling the cable 164 is de-energized.

Abstract: 519,811. Phase modulation. STANDARD TELEPHONES & CABLES, Ltd., and SAMSON, G. G. Oct. 4, 1938, No. 28790. [Class 40 (v)] [Also in Group XXXVI] Apparatus for measuring phase modulation by converting it into amplitude modulation which is then measured, comprises two valves supplied respectively with the voltage under test and an unmodulated voltage of the same frequency. The voltages are combined in a common load to the two valves, phase shifting and amplitude regulating means being provided to adjust the phase and magnitude of the voltage across the common load into quadrature and equality with the voltage being measured. In Fig. 2 the oscillation under test is connected at 1.2 and the voltage developed across the circuit 5.6 and resistance 7 is applied to one pair of the deflecting plates of the cathode ray tube 32. A portion of the voltage is applied to the grid of the valve 8 which has a load 26, 27, 28 in common with valve 20 to which is applied, through phase shifting network 18, the unmodulated oscillation. The voltage, developed across the common load, which is a combination of the two out-of-phase oscillations to produce an amplitude modulated voltage, may be examined by modulation meter 35 or may be applied to the other two deflecting plates of the C.R. tube. When the phases throughout the circuit are correctly adjusted the trace on the screen is circular and will show phase modulation by a thickening of the trace in the direction of the axis joining the deflecting plates connected to the common load. Amplitude modulation will be shown by a thickening of the trace along. the axis at right angles.
