Title: Improvements relating to radar calibration
Inventor: HANSEN ROBERT JAMES
IPC: G01S7/40
Filed: 1958-10-24
Abstract: 897,389. Radar. GENERAL ELECTRIC CO. Oct. 24, 1958, No. 34208/58. Class 40(7). An arrangement for calibrating a radar system which receives an echo in a plurality of channels each having associated therewith a respective differently directive reception pattern, comprises a source of recurrent keying pulses, means responsive to each keying pulse for generating a plurality of narrow pulses, each of the narrow pulses occurring at a time with respect to the keying pulse corresponding to the range time to the intersection of a simulated path of movement of an object with the effective centre of a respective reception pattern, and means for applying each of the narow pulses to the channel associated with its respective intersected pattern. In Fig. 3 the keyer 1 produces regularly recurring pulses, a proportion of which are used to trigger a sawtooth generator 15 through the count-down unit 14. The sawtooth output is fed to a number of flip-flop circuits 16, one for each receiver channel, which are biased by controls 13 so that each is triggered at a time corresponding to the range at which a target flying at a constant height would intersect the centre line of the corresponding reception pattern. The output pulses are differentiated in units 17, shaped to produce gating pulses in units 18, and used to gate the amplifier 20. Oscillations at radio or intermediate frequency from oscillator 21 are passed through the gated amplifiers 20 to the respective receiver units.

IPC: G21F9/00
Filed: 1954-11-25
Abstract: 879,831. Purifying radio-isotopes. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 25, 1955 [Nov. 25, 1954], No. 34253/54. Class 39(4). Polonium 210 is recovered from an inorganic acid solution of neutron-irradiated bismuth by bringing the solution into contact with silver of extended surface area so as to deposit the polonium 210 on the silver. The inorganic acid should give rise to halogen ions but should have substantially no solvent action on silver. The silver is preferably in the form of superposed discs of fine gauze welded at their edges to produce pads which are arranged in a column through which the solution flows; alternatively particulate silver may be employed. The solution is formed by dissolving neutron - irradiated bismuth oxide enclosed in an aluminium envelope in boiling hydrochloric acid; the solution is cooled, e.g. to 25‹-30‹C. before passing through the column. The polonium may be transferred to another surface by heating the silver gauze to 300‹-1000‹C. in vacuo.

Patent GB-200533-A (GB)
Title: Improvements in colloidal-chemical processes for purifying substances
IPC: B01J13/00
Filed: 1921-12-30
Abstract: In the usual process for peptizing substances, for example clay, ores, or graphite, by the addition of electrolytes, the latter are so chosen that they eliminate the ions which tend to hinder peptization, such as calcium or sulphate ions, and thereby a purification of the required substance is effected.  In addition to the purifying electrolyte, which may for example be an oxalate or citrate of an alkali metal, of ammonia, or of an organic base, there are preferably present hydroxyl ions, which, in the case where the substance contains sulphate ions, may be added in the form of barium hydroxide. In examples, crude kaolin is suspended in water and treated with sodium oxalate solution, and a suspension of clay is treated with sodium oxalate and with barium hydrate.  The purified substances may be obtained from their suspensions by known methods.  Specifications 6560/09, [Class 87 (i), Bricks &c.], and 168,927, [Class 82 (ii), Washing granular &c.], are referred to.  Reference has been directed by the Comptroller to Specifications 175,050, 184,271, and 186,855.

Title: Improvements in or relating to the wrapping of the necks of bottles and like articles
Inventor: KRONSEDER HERMANN
IPC: B65C3/22
Filed: 1969-07-11
Abstract: 1,268,275. Labelling bottles; caps for bottles. H. KRONSEDER. 11 July, 1969 [12 July, 1968; 11 Sept., 1968], No. 35096/69. Headings B8F and B8T. A label 53 and a foil neck wrapper 55 are simultaneously applied to a non-rotating bottle 25 at a station 47, the top of the wrapper projecting above the bottle top. The wrapper is progressively wrapped and smoothed around the neck at stations 74, 81, 87, 100 and the top is progressively bent over the bottle top at stations 100, 108 and the bending over may be initiated at stations 86, 87, the bottle being rotated at all these stations. Bottles are fed by a spacing screw 28 to a star wheel 26 whence they are supplied to a rotary turret 36 where they are clamped on turntables by freely rotatable plungers 37. Labels 53 and wrappers 55 are extracted from reciprocating magazines by a glued transfer cylinder 49 and are transferred to a labelling cylinder 48 where they are retained by clamping fingers. The body labels are applied in conventional manner but the neck wrappers are initially applied by a cam actuated pad 67 and air jets 66. The bottles then pass a fixed flexible flap 73 which curls the leading edge of the wrappers round the bottle necks. A roller 75 and a fixed flap 77 then engage the bottles, which are now rotated, after which stationary flaps 82, 83 smooth the wrappers 55. The rolling-on of the wrappers is completed at stages 84, 86, 87 by rollers 85. At these stages, the upper rollers may be inclined to press the top margin of the wrappers 55 inwardly. The plungers 37 are then lifted and the bottles are transferred to a conveyer, with cradles 88 which accommodate bottles of different diameters, which cooperates with a stationary friction rail to rotate the bottles and convey them past the stations 100, 108 to complete the folding over and smoothing down of the wrappers. At station 108 the bottles pass under one or more floating smoothing bars (which may be mechanically vibrated by vibrators to enhance their effect) which have a tapered groove followed by a flat part at the end where the top of the wrapper 103 is twisted, centred and flattened against the top of the bottle. The floating bars accommodate bottles of different heights. The body labels 53 are smoothed concurrently by rollers 115, 116. In a modification, the smoothing bars comprise complementary parts hinged together at the point of entry of the bottles and spring- loaded at the exit end. Both crown capped and corked bottles may be processed. For bottles with corks, the clamping plungers 37 may have stop collars which can engage the bottle top even if the plunger fails to engage the cork. The foil wrapper may comprise aluminium foil bonded to a paper ply by wax.

Title: Improvements in or relating to control arrangements for automatic vending machines
IPC: G07F5/24
Filed: 1963-09-06
Abstract: 1,027,082. Change dispensing in vending apparatus. M. HARTING, [trading as WILHELM HARTING WERK FUR ELEKTROTECHNIK UND MECHANIK]. Sept. 6, 1963 [Sept. 11, 1962], No. 35280/63. Heading G4V. In a vending machine from which goods are dispensed from a number of storage shoots and change is dispensed according to the goods selected, the change dispensing devices are operated electrically according to a pattern of contacts made when the selected dispensing mechanism operates. In Fig. 1, one of the upright bars 2 is displaced to the left about its pivot 1 when an associated dispensing mechanism is operated. Pegs 7 selectively placed on the horizontal bars 3 cause a preset pattern of the bars 3 to be displaced by each of the bars 2 so as to energize the required coin-dispensing devices by means of contacts 5. In Fig. 2, actuation of vertical bars by downward displacement on actuation of an associated dispensing mechanism drives preset contact studs 4 on to selected ones of the cross wires 11 to complete circuits to appropriate ones of the coin-dispensing devices. In Fig. 3, goods selecting buttons 16 cause the energization of goods dispensing solenoids 17 and also of change producing solenoids 18. Actuation of a solenoid 18 depresses a vertical bar 19 corresponding to the goods dispensed with contact pins 26 arranged to connect those horizontal bars 23 to give the required change. Change is dispensed by a relay 30 according to which of the segments 24 of a rotary switch arrangement are connected over the cross bars. Where goods are dispensed electromagnetically by a selectively actuated solenoid on an ejector slide, the solenoid can be provided with a contact set selected contacts of which may be put into service by contact studs in a printed circuitboard so as to select the appropriate changedispensing devices.

Filed: 1966-08-08
Abstract: 1,097,844. Laminated trim panels. ALLEN INDUSTRIES Inc. Aug. 8, 1966 [Aug. 13. 1965], No. 35406/66. Heading B5N. A method of making a composite decorative trim panel comprises the steps of applying a coating of a heat reactable adhesive between the opposed surfaces of a substantially impermeable face sheet 10 (Fig. 1) and a resilient compressible pad 22, the pad incorporating water at least on one surface thereof in an amount sufficient to generate steam which permeates the assembly on subsequent heating thereof when disposed between two die halves 40, 42 (Fig. 5). The face sheet may be of any suitable thermoplastic material 12, e.g. vinyl films, or fibrous material rendered impermeable by the application of a barrier layer, e.g. acrylic or styrene lattices, and is preferably supported by a fibrous sheet 14 which may be adhered to its inner surface as shown, or to its outer surface, Fig. 2 (not shown). The adhesive between the sheet 10 and pad 22 may be any thermosetting adhesive compatible with the material used for the face sheet and pad, e.g. polyurethane adhesives, vinyl adhesives, rubber based adhesives or styrene adhesives. The adhesive is preferably sprayed on the pad with an overlying aqueous layer. The face sheet is superimposed on the pad and the assembly positioned between the upper and lower die halves 40, 42 with the face sheet 50 adjacent the die 42 having a preselected contour 46 in its face. Compression is effected along the upstanding die portions 46. The dies are heated causing conversion of the water to steam which permeates through the assembly and exerts a pressure against the internal surface of the face sheet in the uncompressed areas thereof. Heating is continued for a time sufficient to effect at least partial curing of the adhesive and penetration thereof through the compressed portions of the pad. The pad is preferably provided with a fibrous reinforcement layer 26. In a preferred embodiment, Fig. 7, the lower die consists of a steel frame 66 within which a porous contoured matrix 68 is mounted. Vacuum is applied to a cavity 70 below the matrix and through the matrix to the face sheet 78. Preferably the face sheet is preheated to a temperature in excess of that of the lower die, prior to its placement thereon, to achieve improved definition of the pattern imposed during pressing.
