Title: Loading pallets
IPC: B65D19/00
Filed: 1968-02-22
Abstract: 1,200,023. Load-handling pallets. ECE PATENT A.B. 22 Feb., 1968 [23 Feb., 1967], No. 8709/68. Heading B8H.

Title: Improvements in automatic frequency control of radio receivers
IPC: H03J7/04
Filed: 1941-07-11
Abstract: 550,567. Automatic tuning correction. STANDARD TELEPHONE & CABLES, Ltd., and EARP, C. W. July 11, 1941, No. 8784. [Class 40 (v)] The local oscillator of a superheterodyne receiver is varied in frequency to compensate for frequency drift of the received carrier by means of a voltage derived from a frequency discriminator, this voltage being applied to the local oscillator control through a circuit the timeconstant of which is varied according to the strength of the received carrier. In this way the frequency control is quickly operative in the presence of signals, and only operates slowly during periods of interruption or fading. The frequency discriminator D1 is fed from an I.F. amplifier IFA and the resultant voltage is fed to the control element FC through a circuit containing a series resistance R and a shunt condenser C. The element FC controls the frequency of the local oscillator LO in such sense as to keep the'intermediate frequency constant. The resistance R comprises a bridge of rectifiers so biased by a source B that their resistance is very high. When, however, normal signals are present in the IF amplifier, the voltage fed from that amplifier through the transformer T overcomes the bias B and reduces the resistance of the bridge R. The AFC action is thus quick under normal conditions; but during intervals or fading the high resistance of the bridge R allows the condenser C to maintain its charge. The local oscillator may be of the kind described in Specification 550,566, the frequency control voltage being applied to a phase-changing element associated with a loop circuit (Fig. 2, not shown).

Title: Improvements in protective papers and methods of making the same
IPC: B42D15/00
Filed: 1922-03-28
Abstract: 199,806. White, A. E., (Todd Protectograph Co., Inc.). March 28, 1922. Cheques, drafts, and the like.-Safety paper for bonds, bank-notes, cheques, and the like is printed or otherwise marked in indelible ink with symbols which act as a warning and which are concealed by a series of superposed markings or a pattern, comprising a multiplicity of elements forming a non-solid ground, in delible ink, to render the warning illegible until the pattern is removed by erasure. Alternatively the warning may be applied as a watermark, or may be printed in invisible ink which assumes a conspicuous tint if erasure by chemicals is made. The indelible and delible inks may be of the same or different colours, but differ from the colour of the background, and are of a density which does not interfere with the legibility of the inscription to be written thereon. The pattern is of a complex and intricate kind to render reproduction difficult, and is preferably made up by the superposition of two or more simpler patterns which may be printed either simultaneously or successively, the latter method being preferable. Each pattern, as shown, for example, in Fig. 1, comprises a number of small spots of area surrounded by portions of a different colour, the spots being preferably repeated in some geometrical figure so arranged as to prevent straight line effects. Preferably the spacing of the centres, the areas, or the characters of the figures is varied between the superposed patterns to render the resultant pattern more intricate and to conceal the component patterns, and the second pattern may be angularly displaced with reference to the first so that the resultant pattern is capable of infinite variation. The warning matter may be in the form of a word such as " Void," and, as shown in Fig. 4, is printed in staggered relation over the whole surface of the paper. The printing is preferably in the form of broken lines so that the parts of the letters blend with the pattern.

[Class 100 (ii)] In a method of plate printing, the sheet of paper is passed between an inked intaglio printing-surface and an impression cylinder or platen carrying an electrotyped metallic plate which bears in relief the matter to be printed arranged to register with the intaglio matter, the relief plate having been produced by electrotype from the intaglio plate or its replica. The relief projections may be somewhat rounded off or of less height than the intaglio recesses, being so formed by rubbing wax into these recesses before making the electrotype or by grinding down uniformly the surface of an intaglio plate from which an electrotype relief plate is then formed. Alternatively, an impression may be made in deformable metal, a metallic or cellulosic layer being interposed of thickness equivalent to the paper to be printed, and the resultant impression may be used for making the final relief electrotype. The overlay may be used bare or covered with a sheet of rubber, paper, &c., and any indentation marks on the paper may be removed by calendering. The paper may be printed at a low pressure and in a dry or wet state. Specifications 23233/09 and 257,908, [both in Class 100 (ii)], are referred to.
