IPC: G01P5/04
Filed: 1961-05-05
Abstract: 968,510. Anemometers. ELECTRICAL RESEARCH ASSOCIATION. May 7, 1962 [May 5, 1961], No. 16452/61. Headings G1N and G1R. An anemometer has a member 1 carried by one end of an elongated support 2 which is carried at its other end on a mounting 3 which can turn on an axis or an axes transverse to and offset from the centreline of the support 2 so that on deflection of the member by the wind the support 2 and mounting 3 turn on the said axis to move a beam member 7 by an amount dependent on wind strength. The member 1 is a perforated ball and the support 2 is tubular. The turning axis comprises a knife edge, which may be around the edge of a disc 4 as in Fig. 1 for tilting in any direction. Alternatively the support 22 may be an elongated bar 23 transverse of the support (seen in crosssection in Fig. 6) which pivots about one or other of a pair of elongated knife-edges 25 and only tilts in one component direction of the wind and its opposite. The tilting movement is conveyed by a tube 6 to a flat steel beam 7, which is set transversly in the frame 8 of the apparatus, causing it to deflect. An aluminium damper 14 immersed in fluid 13 is adjustably secured by a rod 15 to the beam 7. Deflection of the beam is recorded electrically by strain gauges 12 set at its ends or by inductive elements (not shown) attached below a moving part of the beam.

Title: Improved cam mechanism
IPC: F16H53/00
Filed: 1943-10-08
Abstract: 569,024. Cam mechanism. FAIREY AVIATION CO., Ltd., CHAPLIN, H. E., COSTIGAN, F. J., and REEVE, L. W. Oct. 8, 1943, No. 16499. [Class 80 (iii)] [Also in Group XXXIII] A cam, at least a part of which is spool-shaped having rims at its ends, is capable of both axial and rotary motion to actuate a number of bellcrank levers. The cam a in a casing b is mounted eccentrically on a hollow shaft c which extends through bearings in opposite walls of the casing. Within the end of the shaft projecting through bearing d is a ball-bearing e carrying a spigot f of a bifurcated member g in which is pivoted by a cross-pin h a link j by which axial movement may be imparted to the shaft c and cam a. The hifurcations have lugs k which straddle a fixed rod m, to prevent rotation of link j. At its other end the shaft c has splined thereto a lever p, the hub of which rotates in a bearing q but is constrained against axial movement therein. Lugs r, 11 formed on the walls of the casing carry bellcrank levers s, t and 13, 14 connected respectively to links w and 16 to which motion is to be imparted. For example, rotary movement of the cam may be employed to bring about the bodily raising and lowering of flaps on both sides of aircraft simultaneously to and from their retracted, take-off, cruising, landing and braking positions, whilst axial movement of the cam may be employed to bring about differential movement of said flaps in addition to their bodily movement, or similar movement of upper flaps on said wings. The cam is formed in two parts 17, 18 secured by bolts to one another and to a flange 19 of a collar 20 secured to the shaft c. The levers, which carry rollers v, 15 to engage the cam surfaces, are arranged diametrically opposite one another as seen in Fig. 2 as a result'of which the cam is arranged to be rotated through. less than 180 degrees. The operative face 21 of the upper part 17 of the cam is inclined towards the axis, the inclination varying at different radial planes and decreasing towards one end of the arcuate length of the face to an extent to cause such face to be parallel with the axis. The lower part 18 of the cam is spool-shaped, being formed. with a middle face 22 parallel with the axis, and with two rim portions 23. Diagrammatic Figures are given showing the positions of the mechanism when the aircraft flaps are respectively in their retracted, take-off, cruising, landing and braking positions.

Title: Improvements in devices for determining the intensity of radiation sources
IPC: G01J5/00
Filed: 1961-05-08
Abstract: 936,757. Temperature determination. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 8, 1961 [May 11, 1960], No. 16629/61. Class 40 (3). A device for measuring the intensity of a radiation source moving across its field of view, and more particularly a hot axlebox detector, comprises two radiation sources 2, 3, connected in opposition and associated with a single optical system in such a way that two successive output pulses are obtained when a source passes the device. The optical system may be a concave reflector 4 and radiation from a hot axle box 1 moving in a direction 6 results in a first output pulse from one detector followed by a second pulse of opposite polarity from the other. The peak-to-peak amplitude is a measure of axlebox temperature and a device 5 indicates when the temperature exceeds a permissible value. A numerical count of signals may also be made. Variations in background radiation affect both detectors similarly and are substantially cancelled out.

Abstract: 992,748. Electric selective signalling. EVERSHED & VIGNOLES Ltd. July 31, 1963 [May 1, 1962], No. 16661/62. Heading G4H. The position of a trace 2 on a chart 1 is measured by scanning with a television camera 3. In Fig. 1, as the chart 1 is driven past the camera 3, the camera (with Vidicon tube) repeatedly scans across the chart 1 and across a scale 6 alternately. During a chart scan, a reversible counter 8 counts pulses from a source 9 until the trace 2 is reached. The chart scan is followed after an interval of six scan periods by a scan across the scale 6 to produce pulses which are fed through a gate 10 to output 11 until the gate is closed which occurs when the counter 8, which is being counted down by pulses from source 9 during the scale scan, reaches zero. A generator 7 produces pulses to control the scans and set the counter 8 for counting up or down, except that the latter may be done by datum marks on the chart 1 and scale 6 detected by camera 3. The pulses at output 11 may be recorded on magnetic tape, and may control a machine tool. The position of the trace 2 on a logarithmic scale may be obtained by suitable spacing of the marks on scale 6. In a modification, a single composite scan is done, of the chart 1 until the trace 2 is reached and then to the scale 6. The pulses produced from the scale part-scan are fed direct to the output 11. The camera output signal is gated off during switching from chart to scale, to eliminate noise, compensation being made for any scale pulses lost as a consequence. After a composite reading scan, both chart 1 and scale 6 are scanned completely, followed by an interval of say eleven scan periods before the next reading scan. The speed of the chart 1 may be controlled in accordance with the irregularity of the trace 2 either by comparing stored trace position data with present data and changing speed when the difference exceeds predetermined limits or by having the camera 3 perform an extra scan ahead of each normal scan or scans. Basically circular (rather than linear) traces may be followed (e.g. for gear cutting) by rotating the camera 3. It is also mentioned that by using extra scans and logic circuitry, the one of three traces 2 having least variation from a mean position may be automatically selected for measurements. Logic circuitry may also be provided to recognise lines which bend back or cross. Yellow rulings on the chart 1 for reading by eye are eliminated by an orange filter over the camera 3.

Title: Chain in which the side bars are formed with curved bearing surfaces
IPC: F16G13/07
Filed: 1969-03-31
Abstract: 1,236,301. Making chains; forging. JEFFREY GALION Inc. 31 March, 1969 [27 May, 1968], No. 16842/69. Headings B3A, B3H and B3W. [Also in Division H2]  A method of making a side bar 32 for a chain link 31 comprises clamping the side bar on opposite side surfaces to hold the bar and support the side surfaces in confinement, and mechanically deforming at least one edge surface of the side bar to produce an inward curvature of the edge surface. Flat steel bar stock 50 is fed into a press, in which a parting punch 51 forms a curved end 52. The stock is advanced until the end 52 abuts a stop 53 and the punch is again operated to form the ends 55, 52a, a spring 56 permitting elongation of the blank 54 during this operation. The blank 54 may alternatively be formed by a blanking punch. The blank is placed between a fixed die part 81 and a movable die part 82, which is provided with spring loaded rods 83, 84 extending loosely through a guide block 75. A movable upper die (71) is provided with end stops 94, 95 and side guides 100, 102, Figs. 17, 20 (not shown). On the downward stroke of the die (71) the guide 100 enters between a guide block 73 and the die part 81 and the guide 102 enters between the movable die part 82 and the guide 75. As the blank is deformed, lateral expansion of the displaced material into upper recesses 118, 120 of the die parts 81, 82 occurs to form curved bearing surfaces 41. There is a lesser expansion into lower recesses 119, 121. The displaced material does not completely fill the recesses and the expanded part has curved side edges. The blanks 54 may be induction heated on the edge surfaces prior to being deformed. The flat ends of the blank are then offset so that, as seen in Fig. 1, the left hand end of each link fits inside the right hand end of an adjacent link. Holes are then punched in the ends, the left hand end having an elongated hole (67) and the right hand end a circular hole (66), Fig. 15 (not shown). A pair of side bars, which have been made of the opposite hand, are welded to a barrel 34 to form a link. Successive links are joined by a pin 37 the ends 38 of which are flattened to correspond with the elongated holes (67). In alternative forms, there may be similar lateral displacement on both curved edges (141) (143) of the side bars, Fig. 21 (not shown), or the lateral displacement may be dispensed with, Fig. 24 (not shown).
