Title: Zero-reset device for numerical counters
IPC: G06M1/34
Filed: 1946-09-11
Abstract: 623,045. Counting-apparatus. PRODUCTION INSTRUMENT CO. Sept. 11, 1946, No. 27312. Convention date, Dec. 29, 1945. [Class 106 (i)] A counting-apparatus of the type in which numeral wheels are rotatably mounted on a shaft is zeroized by rotating the shaft, and a stop mechanism is included which positively prevents further rotation when zero is reached. The numeral wheels, except the units wheel 38, each have an associated gear - wheel provided with two pawls 60, 61 for ratchet engagement with grooves inside the rim of the corresponding numeral wheel and the gear-wheels are connected for tens transfer by Geneva gearing on a shaft 46, the associated gear-wheel of the units wheel being rigidly fixed thereto. The main shaft 36 has a disc 37 on one end and a longitudinal groove over most of its length, spring-urged re-set pawls 54 attached to the numeral wheels coacting with the groove. As shown, the counter is driven electromagnetically; the electromagnet 11 is formed with two fields in which armatures are mounted on shafts 27, 28 with arms 29, 30 interconnected by a link, the arm 30 having an extension 34 normally resting on a cushioning member 26 by the action of a restoring spring 32. The extension is linked to a drive arm 42 with a pawl 44 engaging the units ratchet-wheel. Over-travel of the units wheel is prevented by a detent 48 and star-wheel 39, the pawls 54 on all the moving numeral wheels slipping round the shaft 36. To zeroize the counter, the disc 37 is turned in the same direction as the normal movement of the numeral wheels (counter-clockwise in Fig. 8), thus turning the shaft 36. Thus, the pawls 54 will all, as revolution of the shaft proceeds, drop into the groove in the shaft and all the numeral wheels will turn with the shaft, the positions of the pawls 54 being chosen so that the wheels will have the same reading. The units wheel is turned against the detent 48 while the other numeral wheels can turn in spite of their interconnected gearing because of the ratchet mechanism described above. The stop mechanism comprises a member 65 mounted on the shaft 36 and having a hub 66. A dog 76, pivotally mounted at 77 is spring urged against the member 65 which also has a notch 67. A forked control arm is mounted on a post 72 and is frictionally held by a spring 73. It has two extensions, one of which, 71, is raised above the plane of the other, 70. Two pins 68, 69 of different length are attached to the member 65. The normal position of this mechanism is shown in Fig. 9, but when the counter is being zeroized the shaft 36 is rotated counter-clockwise in that Figure. The dog 76 comes out of the notch 67, the long pin 69 rides up the arm 71 and then engages the arm 70 which it rotates clockwise so that the notched end of arm 71 comes into the paths of movement of the pins. On further rotation, the pin 68 passes under the raised arm 71 and the pin 69 finally engages in the notch 80 of the arm 71 as shown in Fig. 14. On releasing the disc 37, the dog 76 snaps into the notch 67 and sets the wheels exactly to zero.

Title: Improvements in or relating to indicating and/or measuring instruments
Inventor: BURNS CHARLES
IPC: G01B11/04
Filed: 1954-09-24
Abstract: 795,525. Photo-electric control systems. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Sept. 26, 1955 [Sept. 24, 1954], No. 27651/54. Class 40 (3). In measuring or indicating instruments operated by radiation emanating from the edge of a member, for example a hot steel strip, a radiation detector operates means to move a member which adjusts the proportion of the radiation which can reach the detector in such a way as to maintain constant the detector output. The position of the member will then indicate the position of the edge. As shown, two measuring units 14 and 15 are mounted on rails 13 above the moving strip 12. They include tubes 20 bearing lenses which direct radiation from the strip through two holes in a bottom plate of each unit. One hole is fixed in size, while the other in each unit is varied by a shutter moving in a direction normal to the motion of the steel strip. Radiation from each hole falls on a separate photo-cell, and the shutters of each unit are operated by means responsive to the difference in the reception of the two cells of the unit, in such a sense as to maintain the response of the two cells equal. The position of the shutter thus gives an indication of the position of the edge of strip 12 which it is observing. In the circuit shown in Fig. 3 the two photo-cells 33 and 34 of unit 14 control in a differential manner servomotor 27 which drives a servo-transmitter 43. In a similar manner a transmitter 43a is driven in unit 15 and the two transmitters 43 and 43a drive a single receiver operating a pointer indicating the width of strip 12. The units 14 and 15 are altered in position by connection with an endless belt 16 driven by a motor 18. As shown in Fig. 4 two control elements 50 and 51 are geared together in a 10 to 1 ratio and are provided with indicating pointers 53. They operate transmitters 54 and 55 connected to coarse receiver 56 and fine receiver 57 which are also geared together in a ratio of 10 to 1. When the misalignment of the rotors of coarse transmitter 54 and coarse receiver 56 is greater than a certain amount the current passing through relay 61 operates switch 60 so that the motor 18 is operated from receiver 56 to bring the units approximately to the desired position. When the misalignment is reduced below a certain amount the two-way switch 60 changes over and the final setting takes place under the control of fine receiver 57. In a modification units 14 and 15 are fixed and movable optical elements are provided to focus the edges of the strip irrespective of its actual width.

Title: Device for measuring lift of the swept back wing of an airplane
IPC: B64D43/02
Filed: 1961-08-01
Abstract: 933,704. Electric indicating systems. SAFE FLIGHT INSTRUMENT CORPORATION. Aug. 1, 1961 (Oct. 26, 1960], No. 27885/61. Class 40 (1). The invention is concerned with measuring the lift of a swept wing aircraft and is said to be based on the fact that in the region of the separation point of the wing the local flow of air varies angularly as a function of change of lift. In all the embodiments a vane is pivoted to align itself with the direction of air flow and at the same time to operate a transducer to give an output corresponding to lift. In certain embodiments the aligning of the vane is servo-operated. Figs. 3 and 4 show a vane 30 attached to a shaft 34 mounted perpendicular to the under surface of the wing. Attached to the shaft is a transducer consisting of a wiper moving over a potentiometer 42 and operating a meter 46. The vane may be biased to, say, a central position by spiral or coil springs (Figs. 6 and 7, not shown). The resistive transducer may be replaced by a magnetic one (Fig. 8, see below). In the arrangement shown in Fig. 11, the vane rotates about an axis 136 which is not at right angles to the wing surface. The arrangement gives a magnified rotation of transducer 150. In the arrangement shown in Figs. 13 and 14, if vane 160 is not aligned with the air flow it rotates shaft 166 giving an output from resistive transducer 176. This output operates a relay 208 to drive a servomotor 182 in the appropriate direction to rotate the entire vane housing into alignment with the airflow. At the same time the output of transducer 176 before the rotor rotates is maintained on an instrument 240 by feeding into a bridge circuit containing the instrument winding an additional output from a further potentiometer 184 driven by servo 182. In the arrangement of Fig. 15 vane 272 is pivoted about an axis parallel to the wing surface at the separation point and at its other end wipes potentiometer winding 86, the entire vane being rotated into alignment with the airflow by servomotor 292. Magnetic transducer.-A magnetic transducer for indicating vane position is shown in Fig. 5 in which a single pole 84 of a magnetic circuit is fed with an A.C., e.g. 400 cycle supply and is magnetically coupled by an armature 74 rotatable with the vane with one or other or both of a pair of adjacent poles 82. The outputs of the two windings are fed through rectifiers 100, 102 to operate motor 116. Potentiometer 92 allows the balance position to be adjusted.
