Abstract: 174,273. Gouldbourn, J., and British United Shoe Machinery Co., Ltd. Dec. 7, 1920. Heels, machines for; breasting.-A machine for operating upon wooden or other Louis or like heels, such, for instance, as a heel-attaching or a heel-breasting machine, is provided with heelholding mechanism similar to that described in Specification 100,111, but arranged so that a greater pressure is applied to the lateral surface of the heel than to the tread surface. The heelengaging members 4, 5, provided with rack portions 2, 3., are connected by a pinion 1, the bearing-surfaces 6, 7 of which are of larger diameter than the pitch circle of the pinion. The friction produced by these large bearing-surfaces causes a virtual locking action when the members 4, 5 have seated themselves on the heel, and in order that, on further pressure being applied to tha. heel, the tread face shall not be injured by the member 4, a yield is provided therein. This, as shown in Fig. 3, comprises a rubber block 12 positioned between the member 4 and a metal plate 13 which has formed on it an upwardly extending shank 14, adapted to slide within the member 4. The plate 13 is prevented from turning and is limited in its downward movement by a cone-ended screw 15 which engages an inclined face 17 at the end of a groove 16 formed in the shank 14. The screw 15 also affords a means of adjusting the initial compression of the rubber block 12 and is locked in the adjusted position by a nut 18.

Filed: 1966-08-02
Abstract: 1,180,218. Delay lines. MARCONI CO. Ltd. 23 March, 1967 [2 Aug., 1966], No. 34650/66. Heading H3U. [Also in Division H1] A dispersive device for pulse compression or for so-called " passive generation " comprises a number of couplings spaced along a pair of waveguides which are themselves non-dispersive or only slightly dispersive. The wave-energy may be compressional or electromagnetic. In the latter case the guide may be of the coaxial type and the apparatus may take the form of two coaxial guides 2A, 2B (central conductors not shown) coupled by apertures 3 and terminated by absorptive means 2D, 2E. The apertures constitute the sources which are fed by waveguide 2A and produce a compressed pulse in waveguide 2B. The arrangement shown is for compressing a signal consisting of a linearly increasing frequency sweep and the spacing of the holes increases in the direction of propagation of the input signal. A mathematical discussion of the spacing of the holes required to give a chosen dispersion is given and the case of a signal consisting of linearly increasing wavelength components is also discussed. The spacing may take in account slight dispersion in the coaxial guides and the size of the coupling holes may be graded to compensate for the attenuation in the guides or to provide a desired frequency/attenuation spectrum. Where compressional waves are used, the propagating medium may be gaseous, liquid or solid, e.g. air, sulphur hexafluoride, water, aluminium, used with or without temperature control. Torsional or transverse modes may be used in solid media. Where the waveguides are solid bodies, the coupling means consists of " necks " of solid material constituted e.g. by spots of welded material or of synthetic resin adhesive.

Title: Improvements in or relating to means for compensating temperature-dependent changes in the attenuation of lines
IPC: H04B3/08
Filed: 1953-12-14
Abstract: 745,193. Telephone transmission systems. SIEMENS & HALSKE AKT.-GES. Dec. 14, 1953 [Dec. 12, 1952], No. 34809/53. Drawings to Specification. Class 40 (4). An arrangement for compensating for cable attenuation changes due to temperature comprises two networks, the first introducing attenuation changes proportional to its existing attenuation and the second introducing changes equal to the difference between the attenuation changes of the cable and the first network. The first network is stated to be normally sufficient for the higher range of frequencies, the deviations for which the second network has to compensate being found only at the lower end of the frequency range. Adjustment of the networks may be effected directly by the cable temperature or indirectly by means of pilot currents in which case a pilot current in the upper range of frequencies may control the first network and a pilot current in the lower range may adjust the second network. Instead, manual adjustment of the networks in accordance with the pilot level may be used. The networks may be in series in the input side of an amplifier or may be in the negative feed-back path of the amplifier. The variable elements of the two networks may be coupled together either electrically, thermally or mechanically.

Title: Paper filler
IPC: D21H17/69
Filed: 1971-07-27
Abstract: 1405751 Fillers BPB INDUSTRIES Ltd 20 July 1972 [27 July 1971] 35310/71 Heading C1A [Also in Division D2] A composite filler for use in the manufacture of paper and other fibrous web is made by preparing an aqueous slurry of a particulate filler, which slurry contains also 1 to 20% of a dissolved or dispersed organic polymeric material based on the weight of particulate filler, and spray drying the resulting mixture to form agglomerate particles. The total solids content of the slurry may be 5 to 55% by weight. The polymeric material may be rendered substantially insoluble in water in or by the process. Thus a water-soluble urea-formaldehyde condensate can be used which loses water-solubility on drying; casein or glue can be made insoluble by the inclusion of glyoxal or formaldehyde; and ammonia-solubilized acidic polymers or co-polymers, e.g. of the styrene-acrylic or styrene-maleic types, can be sufficiently insolubilized by loss of ammonia on drying. Specified fillers include calcium carbonate, especially whiting, ground limestone or ground dolomite. A surface-active agent may be added to the filler slurry. If of suitable consistency, the mixture in the course of spray drying may form fibres upon dispersion in the hot gas stream so that a filiform product comprised of solid filler particles bound together by the polymeric material is formed. The composite filler so made resists attack by acid in the form of alum used in paper-making and so enables whiting to be used as a filler in place of china clay. Dried paper sheets so made also show enhanced capacity-strength balance compared with simi lar sheets made with untreated filler. In paper sizing, the tendency to form hydrophobic froth with rosin soap size is reduced.
