Patent GB-271181-A (GB)
Abstract: 271,181. British Dyestuffs Corporation, Ltd., Rogers, W. D., Stubbings, W. V., and Emerson, F. W. March 1, 1926. Halogenated indanthrones are produced by halogenating in known manner the purified indanthrone obtainable according to Specification 9269/14. Thus the pure indanthrone may be treated with chlorine in nitrobenzene or with chlorine in sulphuric acid in presence of sodium iodide; by the latter method products of low halogen content but fast to bleach and especially suitable for printing can be produced. According to an example, a monochlorindanthrone is obtained by chlorinating in sulphuric acid monohydrate with addition of a little sodium iodide. Specifications 9975/14 and 184,193 are referred to.

Abstract: 1476506 Pneumatic tyre and wheel rim assemblies BRIDGESTONE TIRE KK 19 June 1974 [21 June 1973] 27130/74 Heading B7C A pneumatic tyre 1 is retained on wheel rim 21 after deflation, e.g. due to puncturing, by an inflated tubular bead spacer 12. Bending of the side walls after deflation is restricted by elastomeric inserts S which each have a Shore A hardness of at least 47 and a maximum thickness not more than 15% of the maximum external width of the tyre when inflated to its normal working pressure. The spacer extends radially outwardly beyond the rim flanges 23, and is provided at its crown portion with at least one reinforcing layer. The crown portion is positioned such that it does not come into contact with the tread portion during running under normal load with the tyre punctured. As illustrated, the inserts S are positioned between a two ply radial carcass and a liner (alternatively the inserts may be positioned between the carcass plies, or between the carcass and side wall rubbers 9, and the plies may be bias plies). The spacer 12 comprises two rubberized cord plies 16a, 16b, with cord angles of 0 and 90 degrees, or both 20 degrees, to the circumferential, fillters 18 having a Shore hardness of at least 55, and an elastomeric layer 17. In a practical embodiment, the inserts S had a hardness of 83 and a maximum thickness of 5À4% of the maximum external width of the inflated tyre. Tube 15 and layer 17 were made of rubber or hardness 45 Shore, and the plies 16a, 16b comprised rayon cords. The fillers 18 were made of rubber of hardness 63 Shore as was tread 2. Dimensional and other parameters (e.g. construction of cords) are disclosed in the Specification. The radially outer edges of the inserts S may merge beneath the tread 2 (Fig. 2, not shown).

Filed: 1948-10-20
Abstract: 656,688. Testing radiolocation systems. HUGHES & SON, Ltd., H. Oct. 20,1948, No. 27312. [Class 40 (vii)] [Also in Group XL (b)] Relates to " echo boxes for testing the performance of pulse radar systems in which a pulse radiated from the radar transmitter excites a resonator in a plurality of oscillation modes, the decay time of the pulse re-radiated by the resonator as observed on the radar indicator providing a measure of the over-all performance of the radar. If the frequency of the transmitter or the dimensions of the resonator change, e.g. due to temperature variation, the observed decay time will change giving an erroneous indication of a change in the radar performance and according to the present invention such errors are avoided by cyclically varying the resonant frequency of the resonator over a range greater than the maximum difference between the frequencies of adjacent modes so that the observed decay time will vary cyclically, the average decay time being then dependent only on the performance of the radar. As shown, the echo box comprises a cubical resonator 10 coupled by a wave-guide 11 to an aerial system comprising a dipole 12, reflector disc 13 and parabolic reflector 14, the disc 13 being fixed to the end of a metal plate 15 mounted centrally in the mouth of the waveguide and the dipole being fixed transversely to the plate extending on either side thereof. The resonant frequency is varied cyclically by means of a vibratable phosphor-bronze reed 16 mounted adjacent to and parallel with a side wall 19 of the resonator, the upper end of the reed passing through an aperture in the upper wall 18 to a mounting 17 and the lower free end of the reed carrying a copper-plated soft-iron armature which is vibrated by a solenoid (not shown) mounted on the exterior of the side wall 19. The mechanical resonance of the reed is adjusted to 100 c/s. and the solenoid is energised by a 50 c/s. current. The resonator is sealed from the atmosphere and solder is run into the interior angles and corners to avoid sharp discontinuities. Details of the mountings for the solenoid and reed are illustrated in Figs. 2 and 3 (not shown) and suitable dimensions are given for operation at a wavelength of 3 cms.

Abstract: 282,014. Wrangell, M. de. Dec. 11, 1&<2>6, [Convention date]. Addition to 278,386. D?-:t;:'Mf/.-Relates to a modification of the driving arrangement described in the parent SpMiR- cation. wherein the turntable spindle can be driven alternatively by an electric motor or by clockwork arranged so that when one is operative the other is automatically rendered inoperative, and consists in the provision ol free wheels in the driving trains, so as to reduce the resistance of the inoperative drive. Fig. 1 shows a combined alternative driving arrangement in which a free wheel 9 is arranged in the spring, and clockwork drive to the turntable-spindle 6 and a freewheel 4 in the drive from the motor 1, which is transmitted through the governor shaft 5. The motor casing is suspended from pivots 2 and linked by a rod 3 to a pivoted bell-crank 15 engaging a pin 16 on a rod 12 extending from a pivoted bracket 13 to a pivoted lever 11 adapted to lock a ratchet wheel 10 to arrest the spring and clockwork drive. In this position, the motor is driving and the belt 32 is taut. On application of the internally threaded stem of the clockwork winding handle to the threaded end of the winding spindle 14 the pivoted lever 13 is pressed back and acts through the rod 12 to disengage the lever 11 from the ratchet 10, so that the clockwork now drives, and simultaneously rocks the motor casing 1 to slacken the belt 32, and allows the motor circuit to open at 17, 18. On removing the winding handle from the winding spindle 14, a spring 19 operates the lever 15 to bring the motor into operation and lock the spring motor. The belt 32 and its pulleys may be replaced by a pair of friction wheels. The motor circuit may be broken rapidly to diminish sparking by causing the ratchet wheel 10 Fig. 3, to be locked by a pivoted detent 24 on the lever 11, whereby the circuit at 17, 18 is kept closed; on movement of the lever 11 to release the ratchet, a spring 25 moves the detent 24 rapidly against a stop 41, allowing the contact 17 to open. According to the Specification as open to inspection under Sect. 91 (3) (a), the freewheel in the clockwork drive comprises a number of discs 22, Fig. 6 (Cancelled), arranged between a fixed drum on the turntable spindle 6 and side faces on a wheel fixed to the pinion 8, Fig. 1, which is loose on the spindle.
