Title: Improvements relating to pneumatic vehicle wheel tyres for use either on normal ground surfaces or on ground surfaces which are loose or yielding
IPC: B60C11/01
Filed: 1955-11-03
Abstract: 785,097. Pneumatic tyres. PIRELLI SOC. PER AZIONI. Nov. 3, 1955 [Nov. 11, 1954], No. 31470/55. Class 144 (2). A pneumatic tyre for use on both hard and soft surfaces comprises a substantially flat main tread 1, extending not less than two-thirds the maximum carcase width C, from the side edges of which, radially inset from its outer roadcontacting surface, laterally project auxiliary circumferential tread elements 3 which are brought into load-sharing ground contact only on soft ground into which the main tread penetrates, the elements 3 each having a radially outer surface which slopes radially inwardly and axially outwardly from the main tread at such an angle that in the flattened road-contacting region of the tread the surface becomes substantially parallel with the axial direction. The elements 3 may be either continuous or discontinuous circumferentially of the tyre, and their radially outer surfaces may subtend an obtuse angle α, within the range 91 to 140 degrees, with the side surface of the main trend 1. The degree of radial inset of the elements is such that on normal hard road surfaces, the surface of the main tread 1 only, even when the tread 1 is completely worn, comes into road contact. Specifications 700,435, 726,810, 755,990 and 769,325 are referred to.

[Also in Division B7] In a tyre servicer comprising a storage unit including a liner storage roll 201 from which liner 97 extends round a drive roll 202 to a storage roll 203 for both liner and tyre fabric and means for rotating the rolls 202, 203 in either direction to wrap liner on or uncoil it from the stock roll 203, a pulley 123 driven by a conveyer belt 14 carrying tyre fabric is selectively engageable via a transmission with the roll 202 to drive it at a speed substantially equal to that at which tyre fabric is fed to the storage unit so that the fabric is stored at zero tension. As shown, two horizontally rotatable wheels each carrying four storage units 197- 200 are mounted on a common support for indexing on a vertical axis between a loading position and one in which tyre fabric is supplied from a selected roll 203 to a rotating tyre building drum, the drum speed being synchronized with that of roll 202 to apply the fabric at zero tension. As a wheel is indexed 90 degrees to move a selected storage unit to its lowermost position a cam 280 causes arms 253 to extend the liner to form an apron for supporting the tyre fabric. A conveyer 62 pivotable about a pin 86 by a piston-cylinder (not shown) controlled by a detector 96 for properly centring tyre fabric with respect to the liner is also selectively movable from a loading (full-line) to a by-pass (dot-dash line) position to drop the fabric back on to the conveyer 14 which carries it to another servicer in line.

Abstract: 1346796 Shutter-operating mechanism HATTORI TOKEITEN KK 6 July 1971 [23 July 1970] 31700/71 Heading G2A In an electric shutter operating mechanism for a camera, first, second and third driving members 5, 10, 15 co-operate with one another and with a shutter ring 1 and an electromagnet 21, to actuate the shutter. The first driving member 5 is held by an abutment 9 against release lever 25 and when the latter is released, first spring 11 co-operating with the first and second driving members forces abutment 8 anticlockwise so moving stop 3 of the shutter ring to release the shutter. This causes switch 5 to flip over to contact 31 so closing a control circuit comprising the electromagnet and allowing a capacitor (34, Fig.4, not shown) to charge through photoconductor (33) at a rate dependent on the prevailing brightness; the electromagnet energized by closure of the circuit then holds the armature 19 provided on third member 15, both the forces of springs 11 and 24 being dissipated. When the capacitor (34) is charged to a predetermined value the control circuit is triggered to deenergise the electromagnet, so allowing one arm  of member 15, co-operating with member 10 by a pin and slot 13, to be driven clockwise against the action of spring 24. Another arm 18 then engages pin 4 of the shutter ring to flip switch 5 back to 30, to close the blades.

Title: Method for washing liquid hydrocarbons from used solid adsorbents
IPC: C10G25/08
Filed: 1953-11-17
Abstract: Spent solid adsorbent (of particle size about 4-100 mesh), which has been used in the refining at elevated temperature of liquid hydrocarbons and still has liquid hydrocarbon entrained with it, is freed of the liquid hydrocarbon by passing it while still hot downwardly against a rising flow of a solvent for the hydrocarbon, the adsorbent passing through the solvent mainly in the form of a column but with a body of liquid above the column. In this way, the hot adsorbent entering the liquid body is rapidly cooled to a temperature at which the solvent removes from the adsorbent the entrained hydrocarbon but does not remove to any great extent the impurities which the adsorbent removed from the hydrocarbon in the refining stage.  Adsorbents mentioned are fuller's earth, bauxite, bentonite, bonechar, charcoal, magnesium, silicate, heat and acid-activated kaolin, acti-vated carbon, silica gel, alumina gel and mixed silica-alumina gel. Liquid hydrocarbons which may be refined with the aid of the adsorbents include mineral oils and particularly petroleum lubricating oils, distillate fuel oils and lower boiling petroleum fractions.  The refining treatment may effect decolorization, neutralization, improvement of demulsibility, the removal of undesired hydrocarbons from liquid mixtures of hydrocarbons by adsorption, or the removal of suspended colloidal or dissolved impurities such as carbon, coke, oxygenand nitrogen-containing compounds and other gum-forming compounds. Petroleum lubricating oils may be diluted with naphtha before refining, in order that the refining may be carried out at a lower temperature.  Solvents mentioned are carbon tetrachloride, n-heptane, n-octane, petroleum naphtha and carbon disulphide. Apparatus is described in which hot hydrocarbon oil, for example, petroleum bright stock, is treated countercurrently with adsorbent, for example, in order to decolorize the oil, the spent adsorbent falling by gravity from the bottom of the treater and passing while still hot to the washer.  In the washer, the adsorbent forms a descending column, while solvent passes countercurrently thereto and forms a body of liquid above the column.  The liquid drawn off from the washer is fractionated to obtain solvent and reclaimed oil, the solvent being recycled to the washer and the reclaimed oil being recycled to the treater. However, some of the liquid drawn off from the washer may be recycled as such, being reintroduced either at a higher point in the washer or into the feedline supplying hot spent adsorbent to the washer, thus aiding in the rapid cooling of the adsorbent. Various constructions of the washer are described.  The adsorbent from the washer is dried by means of stripping gas and then passed to a regenerator, wherein carbonaceous contaminants are burnt off. The regenerated adsorbent is then recycled to the treater.  In the examples, mineral lubricating oil is decolorized with fuller's earth and the spent fuller's earth is washed with naphtha.

In a process for separating a gas mixture e.g. air comprising extracting thermal energy from the head of a rectification column 1 operating at substantially atmospheric pressure by means of a medium e.g. nitrogen, compressing said nitrogen in a compressor 3 passing at least part of it through a coil 7 within the boiler 2 thereby supplying energy to the latter and then expanding said nitrogen at a valve 12 prior to feeding it to the column head, thermal energy is extracted from at least part of said nitrogen by a refrigerator 9 of the reversed hot gas engine type such as is described in Specification 695,857 [Group XIII], located between the compressor 3 and the expansion valve 12. As shown the refrigerated and expanded nitrogen is fed directly into the column to serve as reflux and nitrogen from the column head traverses a duct 20 and a heat exchanger 5 which cools incoming air, and part is bled off through a duct 22 whilst the remainder is forced by the compressor 3 back through the exchangers 5, 7 to the refrigerator 9. In a modification a portion of the compressed nitrogen leaving the exchanger 3 by-passes the boiler 2, is liquefied in the refrigerator 9 and the combined streams are then expanded at valve 12 and supplied to the head of the column. In a further modification the energy-extracting nitrogen traverses a closed cycle formed by the provision of a condenser vaporizor 33, Fig. 2 (not shown), in the head of the column ; the refrigerator being located between the compressor and the boiler.

IPC: H01J23/24
Filed: 1967-07-11
Abstract: 1,198,482. Velocity-modulated beam tubes. GENERAL ELECTRIC CO. 11 July, 1967 [29 Sept., 1966], No. 31960/67. Heading H1D. An electron beam device, in particular, a travelling-wave tube or klystron, comprises an interaction structure having an array of coupled elements so dimensioned and disposed that the interaction in the array is log periodic with frequency. The term "log periodic" when applied to an array of elements signifies that the elements are so dimensioned and disposed that some electrical property, e.g. impedance or resonant frequency, recurs at a succession of frequencies which form a geometric series. Such an array may have wide-band properties. As shown, the amplifier of Fig. 1 comprises an array 33 consisting of coupled resonant cavities 11-21 of annular form, the relevant dimensions of the cavities being progressively reduced in a fixed ratio from the input end to the output end of the amplifier so that they provide a geometric series of resonant frequencies. The resonant sections incorporate tubes 36-46 of decreasing length which define a drift space for an electron beam travelling from cathode 65 to anode 60. The cavities are coupled by a line 79 which extends from input terminals 78 to output terminals 78<SP>1</SP>. Different frequency components in the input and output signals interact with the electron beam at different positions along the length of the array. In a modification (Fig. 2, not shown), the array consists of a helix of progressively reduced pitch and diameter defining a surface of frusto-conical form. In a further modification the array is in the form of an interdigitated series of annuli which again define a structure of generally frusto-conical form (see Fig. 3, not shown, and Specification 1,198,483). The invention may be applied to devices using both fast and slow waves and operating in either forward or backward modes. The devices may use, in addition to those shown, bifilar and magnetron type arrays. The generating ratio of the geometric series on which the arrays are based preferably lies between 0À90 and 0À95.
