Title: Improvements in wireless and like signalling apparatus
IPC: H04B1/16
Filed: 1933-02-01
Abstract: 414,382. Valve circuits for wireless reception. ROBINSON, J., and BRITISH RADIOSTAT CORPORATION, Ltd., 24, Throgmorton Street, London. Feb. 1, 1933, No. 3141. [Class 40 (v).] In a highly selective receiver in which the sidebands are considerably attenuated, distortion is corrected by the provision of an additional resonator, tuned to a frequency differing from the carrier and such that a sloping part of the response characteristic of this additional resonator is in the opposite direction to the slope of the response characteristic of the resonator tuned to the signals for a sideband range of the signals. The additional resonator may be broadly tuned, and is preferably tuned to a frequency differing from the carrier by an amount equal to or greater than the highest modulation frequency required for reproduction. Additional resonators tuned to intervening frequencies may be provided. Adjustment of the additional resonator frequency may be employed as a tone control and additional tone correction in the audio frequency circuits may be provided so that the additional resonator may be used to increase the selectivity. The resonator may comprise a piezo-electric crystal arranged in a bridge system with a compensating condenser as described in Specification 337,049, [Class 40 (v)]. Specification 344,869 also is referred to.

Title: Improvements in blow moulding hollow plastic articles
Inventor: WARD GORDON
IPC: B29C49/06
Filed: 1963-01-25
Abstract: 978,672. Blow moulding hollow articles. E. R. HOLLOWAY Ltd. Dec. 17, 1963 [Jan. 25, 1963], No. 3242/63. Heading B5A] In apparatus for injection - blowing hollow articles there is at least one pair of mandrels, one of which is located in an injection mould while the other is located in a blow mould, and after removal of the blown article the mandrels are transposed so that the parison formed on the mandrel in the injection mould is located in the blow mould and the mandrel from which the article has been removed is in the injection mould. The injection apparatus 1, Fig. 1, includes a hopper 2 and a nozzle 6. The mould section 12 is mounted on a fixed platen and the mould section 13 is mounted on a platen 10 movable by an hydraulic ram 11. Between the mould sections 12, 13 is a mandrel carriage 14 comprising two pairs of mandrels 15, Fig. 3, which extend downwardly from and communicate with passages in discs 24, each mounted on a shaft 23a which carries a pinion 23 meshing with racks on rods 19, Fig. 4, extending from the piston rod of a jack 17. In the operative positions the mould sections 12, 13 define four moulds 32, 33, 34, 35, Fig. 6, of which the two central ones 32, 33 constitute parison moulds and the outer ones 34, 35 blow moulds. The parison moulds 32, 33 receive material from the injection nozzle 6 to form parisons while the outer mandrels are located in the blow moulds 34, 35. The mould sections 12, 13 are separated and the jack 17 operated to rotate the discs 24 through 180 degrees so that parison loaded mandrels are located in the blow moulds and the other two mandrels are located in the parison moulds. The injection apparatus is again operated to form two more parisons while air is blown through the outer mandrels in the moulds 34, 35 which are subsequently cooled before the mould sections 12, 13 are separated. A pair of hydraulic rams 39 are then operated to actuated mechanical strippers 36, Fig. 3, which push the finished articles from the two outer mandrels before operation of the ram 17 to transpose the mandrels and repeat the cycle of operations. In another example, vertically separable mould sections are suggested.

The flow of steam takes place through the inlet 5, through the lower compartments 9 of the base tubes B<1>, up through the inner tubes 20 and downwardly through the outer tubes 16 to the compartment 10, and thence through a boss 22 in the central body A to the outlet 6. A central Field-tube 25, 27, is connected with the central body A. In the arrange. ment shown, four base tubes B<1>, B<2>, B<3>, B<4>, are employed, but any suitable number, preferably not exceeding six, may be used. A coil D, Fig. 2, surrounding the tubes B<1>, B<2>, and having a steam inlet 29 and outlet 30 may be arranged near the bottom of the vessel 4 and used for heating the liquid while the vessel is being filled, and before admitting steam to the Field-tubes, thus preventing caramelizing of the liquid in the latter tubes. The tubes 16 are held in their relative positions by means of a member having a number of radiating arms provided with holes, through which pass screws engaging recesses 19 in the caps of the tubes 16. These arms may also support an inverted conical funnel over the series of tubes 16, the hot liquid rising up inside the funnel and flowing down over the outside.

Abstract: 1291255 Interference suppression in radar receivers MARCONI CO Ltd 30 Oct 1969 [24 Jan 1969] 4152/69 Headings H4D and H4L A radar includes means for producing a signal representing the integral of a representation of the modulation envelopes of received echo and jamming signals, means for producing a signal corresponding to the differential of a representation of the resultant modulation envelopes and means for separating differentiated signals due to echoes. from those due to jamming signals. The radar transmitter pulse has a period T and the receiver I.F. output is passed through a filter of band pass 1/T. The filter output is differentiated by feeding one input of an adder direct therefrom and the second input via a loop delaying the output by an odd number of cycles of the transmitter carrier frequency. Alternatively the delay may be an even number and a subtractor substituted. The delay is maintained at the correct value by a feedback loop including a . frequency discriminator. After differentiation the signals are delayed by T and compared with the undelayed differentiated signals in a coincidence detector. Jamming signals of length different to T are thus removed.
