Title: Improvements in or relating to receiving apparatus for radio navigational systems
IPC: G01S1/30
Filed: 1948-10-08
Abstract: 656,130. Indicating-apparatus. DECCA RECORD CO., Ltd., O'BRIEN, W. J., BRIDGES, D. E., HENDLEY, D. A., EASY, M. H., and VICKERS, J. Oct. 8, 1948, No. 25737/49. Divided out of 656,108, [Group XL (c)] [Class 106 (iv)] [Also in Group XL (c)] Phase-indicating apparatus suitable for use in conjunction with the receiver of the radio navigation system described in Specification 656,108 (see Group XL (c)), comprises an indicator having two rotatable indicating elements driven respectively by two phase comparison means and arranged to traverse a common circular scale. In the embodiment described the output of a phase discriminator operating to compare low frequency input signals is applied to the coils of a crossed coil meter (which may be of the type described in Specification 620,480, [Group XXXVI], to drive a sector indicator 31 which makes one complete revolution over scales 32, 33 and 34, for a 360 degrees phase change. Related input signals of six times the low frequency inputs are also compared in a phase discriminator and operate a similar meter movement which is geared down six to one to drive a six armed pointer mounted concentrically with the sector 31. This pointer has a six to one ambiguity but gives a more accurate indication. In using the combined indicator the arm of the six armed pointer which lies within the sector is the one read and this resolves the ambiguity. The six pointers 35 are equi-spaced and the sector 31 is preferably made to have the same angular coverage as the angle between the arms 35 and may be a transparent plate. The three scales, when the indicator is used in the above-mentioned receiver are illuminated one at a time according to the pattern on which lane identification takes place. Specifications 630,698, 656,123, 656,127, 656,128 and 656,129, [all in Group XL (c)], also are referred to.

Abstract: 751.577. Shuttlecocks. CARLTON TYRE SAVING CO., Ltd. Dec. 1, 1954 [Sept. 8, 1954], No. 26000/54. Class 132(3) A shuttlecock skirt moulding comprising stems B and vane areas G between the stems has the proportions shown in Fig. 1 and is expanded by forcing a steel cone into it so that the diameter D of the free edge of the skirt is increased to diameter D<SP>1</SP>, Fig. 3, the expansion causing the horizontal ribs in the vane areas to be reduced to a thickness which could not be produced by direct moulding. Alternatively, the skirt may be placed between male and female cones, the ribs being held by a plurality of fingers, and intermediatefingers; which bear on the stems, being expanded outwardly. Inwardly directed fluted areas are thus formed by the stretching of the ribs (Fig. 5, not shown). In a further modification, the stems are held and expanding fingers stretch the ribs outwardly. The fluting produced in the modifications may. be non-symmetrical relative to the stems (Figs. 6, 8, not shown), and so impart spin to, or reduce the spinning of the shuttlecock when in flight. Plain vane areas or ones pierced with holes may be used in place of the ribs. Nylon is specified for the moulding.

Filed: 1933-09-21
Abstract: 427,315. Severing pneumatic tyre tubes. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, WILLSHAW, H., SMITH, H., and YOXON, G. H. B., Fort Dunlop, Birmingham. Sept. 21, 1933, No. 26067. [Class 31 (i)] Measuring and cutting apparatus for dividing up long lengths of pneumatic tubes for tyres, tyre treads or bands and like uses consists of a measuring wheel 1 driven by the work or work conveyer 2 and driving a cutter 7 at a different and variable speed, wherein at the moment of cutting the two speeds are equalized by causing the cutter to be driven directly by the work or conveyer. The wheel 1 drives a disc 4, shaft 13, bevel gear 5 and cutter shaft 16, the gear ratio and hence the length to be cut being varied by means of a screw 15. When the blade 7 contacts with the work or conveyer, the frame 11 tilts on the pivot 22, thus lifting the wheel 1 off the conveyer, and the blade is drawn along by and cuts the work. Electrical heating of the cutter is effected by insulated brush rings 18 and contacts 20. In the modification shown in Figs. 4 and 5, the blade carrier 6 is loosely mounted on the spindle 16 and is driven by a lever 26 fixed on the spindle 16 and engaging a pin 25 on the carrier 6. The pin moves in advance of the lever during cutting ; a pad 30 lifts the frame 11, and balance weights 28, or a friction device not shown, prevent the carrier 6 from swinging too freely. The blade 7 can slide in guides 36 under the action of springs 35. In another modification, the pin 25 and lever 26 are replaced by a ratchet and pawl ; and in a further modification, the carrier 6 is held frictionally on its spindle 16 by spring pressure.

Title: Improvements in or relating to radio receiving and to high frequency coupling arrangements
IPC: H03H2/00
Filed: 1935-09-24
Abstract: 463,254. Wireless receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 24, 1935, No. 26468. Convention date, Sept. 29, 1934. Addition to 460,570. [Class 40 (v)] Relates to aerial coupling systems of the kind in which one or more dipoles, each having arms of unequal length, are coupled to a receiver through a two-wire transmission line, so as to cut out inductive pick-up, the arrangement being designed to cover both short and medium wavelengths. As shown in Fig. 1, the crossed dipoles 11, 12 feed shortwave energy directly to the split secondary windings 16 of the transformer 14, and then through the transmission line 22 to the split windings 24 feeding the set 31. For longer waves, signal energy is transferred from a primary winding 19 (in an earthed tapping from the transformer 14) to a secondary winding 17, and then through the transmission line 22 to a winding 25 which is coupled to a secondary 28 arranged in series with the winding 30 across the input to the set 31. In all cases, the signals are fed additively across the transformer-windings, whilst inductiwe pick-up is balanced out or dissipated in the earthed screens 32. Fig. 2 shows a filter arrangement of high-frequency coupling-transformers 34, 35, 36, in which the three primary windings are arranged in series, and graded with the help of shunt capacities 37, so as to transfer, selectively, three different wavebands. The capacities may be arranged in series across the whole of the primary windings instead of in parallel as shown. Fig. 4 shows an arrangement in which each of three separate dipoles 57, 58, 59 responds to a distinct frequency band, and only one coupling transformer 60 is used. In the Specification as open to inspection under Sect. 91 alternative arrangements are described for coupling a single dipole, and also an alternative method of coupling three separate dipoles to the downlead. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,094,248. Selective signalling. HONEYWELL Inc. June 14,. 1966 [June 22, 1965], No. 26508/66. Heading G4H. In an analogue-to-digital converter of the type in which an input signal is integrated for a known period, the effects of a spurious A.C. ripple superimposed upon the input are eliminated by performing the integration for two periods, the first starting with a positive-going zero-cross-over of the spurious ripple, and the second with a negative-going, zero-cross-over. As described the input signal (with the spurious ripple) is applied direct from a terminal. 11, Fig. 1, to an integrator 14 and the ripple is filteredout 12 and applied to a zero cross-over detector 13. A timing pulse 18, intended to start an integration cycle, is delayed from reaching the integrator 14 by a flip-flop 21 until the next positive-going zero cross-over of the ripple occurs, at which instant a pulse passes from " and " gate 16 to open a gate 22. When the integration cycle is complete, the integrator produces a pulse, on a lead 32, which is delayed by a flip-flop 27 and used to start a further integration cycle when the next negative-going zero cross-over of the ripple occurs. The average of the results obtained in the two integration cycles will be independent of the ripple.
