Abstract: 971,464. Electric transducers. SPERRY GYROSCOPE CO. OF CANADA Ltd. Jan. 20, 1961 [Jan. 21, 1960], No. 2361/61. Heading G1N. [Alsoin Divisions G3 and H1] In an automatic positional control system the position of a workpiece relative to a tool is measured by a coarse and fine pick-uff and compared with the required position as determined by data from e.g. a tape record, the coarse pick-off comprising a D.C. potentiometer whose slider is attached to the movable member to produce a unique coarse indication of its position, and the fine pick-off comprising a plurality of inductive members associated with the slide and bed of the machine to give a vernier signal to be added to the coarse signal, an electronic switch changing control from the coarse to the fine signal when the former falls below a predetermined level. As shown (Fig. 2), the movable member of the machine supports a carriage 33, mounted on rollers 35, carrying firstly the coarse pick-off potentiometer 7 whose slider is driven by a pinion 43 and rack 9, and secondly the slider member 46 (Fig. 4) of the fine pick-off which co-operates with a fixed scale member 45. The latter consists of a series of parallel conductive lines 48 on an insulating base 47, joined in zig-zag manner: the movable slider member 46 consists of a plurality of units of conductive lines interconnected as shown, the spacing between the lines being the same on both members. Each coil unit on slider 46 consists of two groups 49 interconnected so that the longitudinal mutual inductive effects between slider 46 and scale 45 are additive, but the axial inductive, and the mutual capacitive effects cancel out. The spacing between coil units on slider 46 produce a desired vernier effect. The appropriate coil unit to be energized is selected by the fine signal from the tape record, and the movable part of the machine is positioned so that the output signal from the scale is zero when the appropriate coil unit on the slider is energized.

Title: Improvements relating to radio beacons for defining landing-paths for aircraft
IPC: G01S1/02
Filed: 1942-02-27
Abstract: 569,406. Wireless beacons. STANDARD TELEPHONES & CABLES, Ltd. Feb. 27, 1942, No. 2591. Convention date, March 6, 1941. [Class 40 (v)] An antenna system for defining a constantintensity glide-path for aircraft, which is substantially straight at high altitudes and decreases in slope near the point of landing, comprises 'a central radiator 10 and one or more auxiliary radiators 17, 18 symmetrically arranged in alignment on each side of it, the array A being located at a height above ground not exceeding two wave-lengths, at one side of, and with its alignment axis inclined to, the vertical plane containing the glide path 200, and behind the landing point 206, the auxiliary radiators being energized at the same frequency but at a lower power level than the central radiator and the factors determining the shape of the horizontal radiation pattern being so adjusted as to produce two lobes which merge into one another along the antenna axis, as shown at 207. The field strength f at. any point at a height Y above ground and a distance R from the beacon is given by #=KF(#)Y/R<2>, where K is a constant and F(#) is the field strength in a horizontal plane at antenna level and is a function of the angle 0 between the antenna alignment and the vertical plane passing through the point and the centre of the antenna array A. This enables, assuming values for the offset 0 and backset D of the aerial A, the form F(#) of the horizontal radiation pattern for a desired shape of glide path to be calculated. This form of pattern is obtained by suitable choice of the factors affecting it, which are the distance S between the auxiliary and central antennµ, and the relative power levels and phases of the energy supplied to them. Diagrams are given showing the effects of offset O and backset D on the form of radiation pattern desired, and the effects of the spacing S and the relative power levels and phasing of the energy supplied to the antennµ on the form of radiation pattern obtained. As shown in Fig. 1, a transmitter 13 supplies energy to the central antenna 10 directly and to the auxiliary antennµ 17, 18 through a phasing unit, the amounts being determined by tuning the transmission elements 11, 20, 21. The spacing S may vary between one and ten wave-lengths. Two radiators may be used in place of each of the antennµ 20, 21, allowing further control of the radiation pattern by variation of the relative powers fed to the two members of each pair.

Title: Improvements in an automatic filter plate moving apparatus in a filter press
IPC: B01D25/172
Filed: 1963-01-21
Abstract: 1,016,259. Filter presses. K.-I. KURITA. Jan. 21, 1963 [June 23, 1962], No. 2594/63. Heading B1D. An automatic filter-plate-moving apparatus in a filter press comprises pair of screw shafts 17, Fig. 1, held in parallel with a row of filter plates 11, a reversible electric motor 19 for driving the screw shafts, and a pair of reciprocating members 24 mounted on the screw shafts and provided with means for engaging and disengaging arms 12 of the filter plates, e.g. a pusher 27. In operation, rotation of the screw shafts 17 causes the members 24 to move backwards towards the end plate 37 on the rear frame 15. The pusher 27, Fig. 2, on each member 24 turns, caught on the arm 12 of the first filter plate 11, and when it has just passed the arm 12 it is turned in the opposite direction by the action of a spring 29, Fig. 3 (not shown), concentric with the screw 28, Fig. 2, of the pusher 27, so that pusher 27 gets into the gap between the said arm 12 and the adjacent arm 12 of the plate behind. Further rotary movement of the pusher 27 is prevented by a supporting piece 30, Fig. 2, loosely inserted in an opening 31 of member 24 and pressed upward by a spring. Each member 24 has a frame 44, Fig. 3 (not shown), provided with a pair of limit switches 45, so that as the rear limit switch 45 approaches the arm 12 of the first filter plate 11 the switch operates to change the direction of rotation of the reversible electric motor 19 and the members 24 go forward, taking the first plate 11 up to the other end plate 41, whereupon the front limit switch 45 operates to again reverse the motor. Hence all the plates are eventually moved up to the end plate 41. Member 24 returns past the end plate 37 and a roller 34 on a lever 33, Fig. 2, engages a beam 36, Fig. I, so that the supporting piece 30 sinks into the opening 31, and the pusher turns as shown in Fig. 5, hence permitting return of member 24 past the arms 12 of all the filter plates 11, the pusher 27 being disengaged. On the upper side of each pusher is provided a pin 39, Figs. 2 and 5, so that when the member 24 approaches the end plate 41 on the movable head 35, Fig. 1, the pin 39 knocks against a stopper 40 and the pusher 27 turns back to the operating position. The plates 11 can be returned to the filtering position by the action of a ram 43, Fig. 1. A safety switch comes into operation to stop the reversible motor 19 of the reciprocating member is brought to rest with a sudden shock, e.g. due to one of the limit switches failing to operate.

Abstract: 1445815 Ball and socket joints NORDISK VENTILATOR CO AS 21 Jan 1974 [23 Jan 1973] 2794/74 Heading E2F [Also in Division F1] A ball joint at one end of a link 12 forming part of a mechanism for adjusting the pitch of fan blades comprises a part-spherical member 20 carried by a pin 16 and co-operating with a complementary member 21 secured to the link by a circlip 24. The members 20, 21 may be of steel with a glass-fibre reinforced nylon coating on one of them. When the fan is stationary, the small force exerted by a corrugated spring washer 25 acting between the member 21 and a spacer ring 23 suffices to hold the members 20, 21 together. When the fan is running, the centrifugal force on the link 12 holds the members 20, 21 strongly together and prevents them from being forced apart by high adjustment forces.
