IPC: B03B5/24
Abstract: 1,054,220. Jigging apparatus. FLOATEX SEPARATIONS Ltd. June 3, 1965 [June 18, 1964], No. 25173/64. Heading B2H. A jig for beneficiating granular, or pulverulent materials comprises a hutch structure in which the hutch 21 is carried on a longitudinal lever frame 25 pivoted about a transverse horizontal axis 16 located beyond the hutch in the down stream direction and connected at its other end to a vertically reciprocating mechanism. This comprises a pitman 19 whose eccentric crank or sheave is driven via speed reduction belts and pulleys 24, Fig. 3a (not shown). Thus, since the transverse compartments of the hutch are each at a different mean distance from the fulcrum 16 of the frame 25, each has a different stroke when the motor 24 is operating, so that in effect each "proton" compartment acts independently. Also at the feed end 2a of the trough 2, the bed of material is subjected to a maximum pulsatory treatment whilst as separation and stratification takes place along the length of the screen the bed of material is less strongly pulsated. A light fraction collector 29 is provided at the discharge end of the screen 7, having a motor driven extractor screw. Heavy pulp is delivered to an outlet gate 38 which is adjustable by means of a hand crank and gears 39, Fig. 3b (not shown). Beneath the lip 28 of the collector channel 29 is a breast plate 41 below which is a baffle 42. A water jet from a pipe 45 is sprayed out of the space between the plate 41 and baffle 42 to oppose any tendency for light pulp and the water surface level A, Fig. 5 (not shown), to be entrained in the downward flow against the baffle. The discharged heavy fraction falls on to a sloping drainage grid 47 which removes the excess water via a shoot 5, the dewatered material being delivered via the heavy fraction shoot 6. In order to adjust the percentage of heavy material in the discharge 'light fraction', the hangers 8 for the screen 7 may be adjusted in length, the screen may be divided into sections, the ragging 27, Fig. 5 (not shown), in the compartments and the perforations in the screen may be varied in size, and the water flow in pipes 11 adjusted. Thereafter further control is effected by adjustment of the output gate 38. A water inlet provides water to lubricate the floor 35 of the machine. The machine is double-ended, and two double-ended machines may be placed side-byside and fed from a common central hopper with a common drive for their hutches.

Abstract: 1,229,481. Temperature compensation of magnetic sensor. NEWPORT INSTRUMENTS Ltd. March 5, 1969 [March 5, 1968], No.10738/68. Heading G1N. [Also in Division H1] The magnetically sensitive negative resistance diode shown has an n-type germanium wafer (18) with (100) major faces bonded to a brass heat sink (12) forming one end of a casing. The diode has both its contacts on the same face. The magnetic sensitivity arises mainly from a contact constituted by a gold-antimony wire (22) (reinforced with a silver coating (24) over most of its length) which has been screwed into contact with the wafer and pulse-bonded thereto. As essentially ohmic contact is formed by electro-plating a copper annulus concentric to the point contact and soldering a wire (26) thereto. The diode may be used for magnetic field sensing or measurement and may be used, under reverse-bias, in constant current or constant voltage modes. The diode is temperature sensitive: temperature compensation may be achieved in the constant voltage mode by applying the constant voltage to a combination of the diode and a suitable resistor, and in the constant current mode by taking the difference signal from two suitably chosen orthogonally mounted diodes, on parallel to and the other perpendicular to the applied field. A circuit is described for effecting temperature compensation of a single diode 54 operated in the constant current mode. Both the zero-field voltage and the slope of the field-voltage characteristic are temperature dependent. The zero-field voltage (which varies approximately logarithmically with temperature) is cancelled in difference amplifier 63 by a signal derived from a thermistor 56 fed by a bridge 61 and amplifier 53 to a diode 52 biased to a suitable part of its characteristic and then to an amplifier 60 where it is subtracted from a constant voltage. The corrected voltage V o  from the amplifier 63 is fed as the input to a bridge one arm of which contains a second thermistor, 68, of linear or non-linear characteristics depending on the temperature range to be covered by the compensator; the output of the bridge is a signal corrected for temperature variation of both zero-field voltage and slope of the field-voltage characteristic.

A method of controlling the energy imparted to a sample by a plasma generator used in atomic absorption spectroscopy comprises mixing different gases 32, 34 the first, 32, being a mono or diatomic gas such as helium, argon or neon imparting less energy to the sample than the second, a polyatomic gas such as nitrogen, oxygen, carbondioxide, carbon monoxide or hydrogen and introducing the gas mixture into the plasma generator to form a gas plasma, the sample being introduced either into the gas mixture or directly into the plasma generator. The ratio between the gas supplies may be varied by means of control valves 36, 38, the gas being mixed at tee junction 40 before passing to a nebulizing system 42 where the sample solution is injected and atomized, conduit 46 carrying the gas and sample to the flame tip 30 of the plasma generator housed in tube 28, the energy of dissociation being provided by means of a radiofrequency (RF) transmitter 10 capable of producing several hundred watts in the range 10-1000 megacycles. Radiation passing along line 45 is absorbed by the sample atoms, whose characteristic absorptance is detected by atomic absorption spectrometer 48. By choosing suitable ratios of first and second gases according to the chemical constitution of the sample, the energy imparted by the gas mixture can be varied to achieve maximum dissociation thereof at the ground state of the atoms. A ratio can be established for each element regardless of the compound, but it is preferable to establish a particular ratio for each compound.

Abstract: 1,232,448. Gas fuelled lighters. VAN POPPEL N.V. GEBRS. 5 Aug., 1968 [4 Aug., 1967 (4)], No. 37193/68. Heading F4F. A gas fuelled lighter has a trigger 35 which when operated opens a valve 13 to allow fuel to flow from a first container 7 via a chamber 9 to a duct 11 and causes rotation of a spark wheel 23 mounted at the outlet of the duct 11. The spark wheel 23 is in driving engagement with a bell-crank 24 connected to a push-rod 25, and a spring 39, acting between the trigger 35 and ring 40 on the rod 25, urges the rod 25 against one leg 41<SP>1</SP> of a spring-biased rotatable crank-lever 41. When the trigger 35 is pulled the spring 39 is compressed, then the trigger 35 abuts and rocks a valve lifter 17 to open the valve 13, and finally the trigger 35 abuts the other leg 4111 of the lever 41 to release the push-rod 25 which is then rapidly pushed to the right (as seen in Fig. 1) by the spring 39, thus rotating the spark wheel 23. The fuel container 7 is rotatably received in the lighter-handle 2 and has a gasflow adjustment nut 50 non-rotatably received in the chamber 9. The handle 2 is closed by a plug 6 having a rotatable portion 53 which may be pushed into engagement with the container and rotated to adjust the nut 50. A flint 26 is received in a groove 30 in the lighter and is urged against the spark wheel 23 by a sliding member 27 under the action of a spring 31.

Abstract: 1,253,217. Welding by pressure. R. M. GWYNN, and T. THEMY. 16 Dec., 1968, No. 59777/68. Heading B3R. [Also in Division C7] In a method of making an electrode for electrolytic use, by bonding a foil 13 of metal or metal alloy of the platinum group, e.g. ruthenium, rhodium, indium, or platinum, to an oxidation resistant metal substrate 12 of, e.g. tantalum, niobium, titanium or their alloys, or aluminium, nickel, or stainless steel, a linear zone of contact is established between a cylindrical conductor 16, rotatable in a massive conductor 14, and the foil while the substrate is supported by a second massive conductor, and a pressure of from 10 to 300 pounds per linear inch and current to provide at least 3 kva per linear inch of the zone of contact, at below 12 volts, are applied while the conductor 16 is advanced in a direction perpendicular to the zone of contact at a rate to soften, but not melt, the surface of the substrate. In one embodiment (as shown) the cylindrical conductor 16 is received in a groove 15 of the conductor 14 which may be cooled. The substrate may be surfaced, before bonding of the foil thereto, with a coating of palladium, silver, or other chlorine-resistant metal. The current supply is preferably in the range from 7 to 100 kva at a voltage in the range from 0À1 to 5 volts. The cylindrical conductor 16 may be of tungsten, tungsten carbide or alloys thereof containing less than 25% of cobalt, tantalum and titanium, or stainless steel. The rate of advance of the conductor 16 may be from 6 to 36 inches per minute, and the substrate surface may be heated to from 100‹ to 500‹ C. below its melting point. The massive conductors may be of copper or hard copper alloy, e.g. copper-silver or 2% beryllium-copper. In a modification the cylindrical conductor has an enlarged diameter portion received in a similarly enlarged portion of the groove in the conductor 14. In such a case, at least portions forming the inner surface of conductor 14 are of tantalum, rhodium, gold or their alloys. The second massive conductor may be a bed-plate 10 or a large diameter roll (20) (Fig. 4, not shown) with attendant flat work-supports (24, 25). Current-may be fed to conductor 14 by a plurality of thin, flexible cables. The substrate may be surfaced with the foil over all its surface, or only part thereof, and un-surfaced parts may be coated with resin, glassy ceramic &c. (Figs. 6-9, not shown). A typical alloy substrate is 80-85% titanium with 20-15% molybdenum.

Abstract: 1,257,716. Frictional dampers. K. D. FORTUYN. 19 March, 1969 [22 March, 1968], No. 14442/69. Heading F2S. [Also in Division G1] In a measuring instrument, a movable member (such as a pointer 1, Fig. 1, or a weigh pan 20, Fig. 2) is frictionally damped by the engagement therewith of at least one rotating body having a surface of revolution (such as the shaft 3 of Fig. 1 or the shafts 23 of Fig. 2), the axis of which extends parallel to the direction of movement of the movable member. The friction is thus dynamic as opposed to static friction. The invention requires that the damping effect be adjustable during movement of the movable member. The adjustment may be effected by varying the contact pressure between the member and the body (shaft) and/or the rotational velocity of the latter. Variations in the rotational velocity may be used to control a compensatory adjustment of the contact pressure.  In Fig. 1, the shaft 2 of the pointer 1 is engaged by an arcuately grooved portion 8 of the rotating shaft 3, which is flexible. An electromagnet 7 may receive its currentfrom a source controlled by a transducer (not shown) detecting the contact pressure between the shafts 2 and 3 and attracts an armature 5 at the end of the shaft 3. The shaft being flexible, variations in the electromagnetic force cause corresponding variations in the contact pressure. In Figs. 2 and 3, a disc 28 rotatably mounted on the frame 14 carrying the weigh pan 20 carries two fixed friction pads 31 and one movable pad 32 which is connected by gearing 34 to 38 to a toothed rack 39 fixed on the frame 14. A desired contact pressure, adjustable by varying through a screw 43 the bias exerted on the disc 28 by a spring 41, is applied by this means between the pad 32 and the shaft 23. Should the desired contact pressure be exceeded, the disc 28 will tend to rotate with the shaft relative to the rack 39 and thereby cause the pad to be moved in a direction to reduce the contact pressure. In this way, the desired contact pressure may be maintained. To cause increased damping of the Fig. 2 weighing apparatus at the end of the weigh pan's travel, the shaft 23 may carry a sliding weight 44 having a frictional contact with the shaft and resting on a spring 45 which also restrains the weight against rotation with the shaft. The force exerted by the spring on the weight, and hence the frictional drag, is adjustable by means of a screw 46. When the weigh pan's carrying frame strikes the weight, it moves down, thereby increasing the spring loading and the frictional drag and at the same time partly relieving the load of the weigh pan so that the effective sensitivity of the weighing apparatus is temporarily increased. This increase of sensitivity at the end of weigh pan travel is advantageous when a load being weighed has to be identified as within a specified weight range, as is the case in sorting by weighing.

Abstract: 1,259,625. Laminates. TRW Inc. 20 March, 1969 [21 March, 1968], No. 14769/69. Heading B5N. Composite materials are obtained by forming elements from a matrix material and fibres of another material of different physical properties from those of the matrix material, the fibres in each element arranged half to 30 microns thick substantially parallel to each other and to the layer and uniting the elements to form a selfsupporting mass of substantially greater thickness than that of each individual element. The matrix material may be of lower strength than that of the fibres. The matrix material may be metal, ceramic or plastics and the fibres may be whiskers, and non-crystalline, sintered crystal or polycrystalline in structure. The length to diameter ratio may be 200-10,000. Suitable materials are silicon carbide whiskers, aluminium oxide or silicon nitride. The fibres may be formed as a layer on the matrix material by suspension in a non-polar liquid such as amyl acetate, passing an alternating electrical voltage through the liquid to align the fibres and then drawing the matrix material upwardly through the bath to deposit the fibres on the surface. Alternatively, the matrix material may be mixed with the dispersion as particles and the mixture of matrix material and fibres deposited on the surface from which they are subsequently removed as a self-supporting film. A binder such as nitro-cellulose or polybutadiene may be incorporated in the suspension to assist the adhesion of the fibres. The elements may be laminated by diffusion bonding such as hot rolling and, if the matrix material is a plastic, by polymerization with thermoplasticizing. The fibres of adjacent strata may be angularly disposed. Suitable plastics material for the matrix are polyethylenes, polyurethanes, epoxies, and polyamides.
