Filed: 1924-02-28
Abstract: 234,881. Mooney, D. J. Feb. 28, 1924. Framework; planes, construction of.- Framework members which cross one another are connected together where they cross by securing a channel plate or a block to one member, providing one or more detachable metal bands passing around the other member, and tightening each band by drawing the ends together by a bolt and nut securing them to the plate or block. Fig. 1 shows one arrangement for connecting a spar a to one of the tubular booms b of the rib of a wing framework. A plate c, Fig. 3, bent to channel form, Fig. 5, and shaped to fit over the spar a, is riveted at d to the spar and the boom b is placed between the side walls e of the plate. Metal bands f pass around the boom and the ends of each band are connected together by a bolt g passing through the walls e and through a distance piece between the walls, and are tightened by a nut. The distance piece may be tubular or may be a block, shaped as shown in Fig. 6 to fit against the boom. A block, shaped as shown in Fig. 7, may replace the channel plate and the distance piece. Specification 158,999 is referred to.

Abstract: 285,507. Geles, J. Feb. 19, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Sawing.-In a machine for filing, surfacing, sawing, grinding, polishing or like work, a reciprocating tool mounted in a holder 14 and consisting of a blade 17 to which is secured an abrasive covering 18, is driven from an electric motor 7 through a coupling 8, shaft 5 and connecting rod 11, the gearing being contained in an oil-tight casing 4. In a modification, the motor is mounted on the base of the machine and is connected by a belt to a pulley 9. The tool is guided by upper and lower rollers 19, the upper roller being spring-mounted on an adjustable member 21 and serving as a guide to hold the work on the angularly-adjustable table 2. In a modification, the member 21 may be suspended from a ceiling fitting 26, Fig. 6, by means of a tube 25 and stay-ropes 27. A pump 29 driven from the shaft 5 and connected by a pipe 30 to the hollow upper part of the member 21 supplies cooling fluid to the tool. For some work the tool is replaced by a file of anv desired cross-section. The invention is applicable to the working of steel or other metals, glass, marble, cement, &c.

Title: Apparatus for use in sowing seed potatoes or the like
IPC: A01C5/02
Filed: 1952-02-29
Abstract: 699,063. Planting-tools. MUTCH, J. F. Feb. 29, 1952 [March 6, 1951], No. 5395/52. Class 6(ii) A tool for sowing potatoes or the like comprises a tubular member 1 provided with a blade 7 which is open at one side. A deflector 19 pivotally mounted on pins 13 is movable to close the opening in the blade 7 and is provided with a driving pedal 20 and a deflector pedal 23. The member 1 is forced into the ground by means of handles 2 assisted by foot pressure on the driving pedal 20 which forces the deflector 19 into contact with the blade 7. Downward foot pressure on the deflector pedal 23 causes pivotal movement of the deflector 19 to enlarge the hole made in the ground and allow a potato 22 to enter the hole on withdrawal of the device. The depth of penetration into the soil is determined by a removable block 21 mounted below the pedal 20. A container for potatoes may be attached to a hook on the member 1 and a potato slicing blade may be provided in the container.
Patent GB-564710-A (GB)
Title: Improvements in or relating to the balancing of electrical bridge circuits containing a non-linear element
IPC: G01R17/16
Filed: 1943-04-05
Abstract: 564,710. Voltage, current, and resistance measurements. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. April 5, 1943, No. 5401. [Class 37] A Wheatstone bridge circuit has a non-linear impedance in one of the arms and a supply voltage applied across one diagonal, the non- linear impedance, or an ohmic resistance in another arm being biassed in such manner that the bridge balance is not affected as the supply voltage varies over a limited range. The non- linear impedance may be the anode-circuit of a valve, or a thermistor, and the current or voltage to be measured or indicated may be applied to the valve grid or to the heating coil of the thermistor. In the valve voltmeter shown in Fig. 4, an alternating voltage to be measured is applied at 3, 4 to a rectifier D giving a D.C. voltage across the load resistance R5 which is smoothed by a resistance R6 and condenser C2 and is applied to the grid of the valve V. The bridge arms comprise resistances R1, R2, R3 and the anode-cathode path of the valve V in series with the cathode lead resistance Rc. Supply voltage is connected across one diagonal at 5, 6 and a meter M is placed in the other diagonal. To render the bridge balance independent of supply voltage variations, a positive voltage from a potentiometer R4 is connected in the grid circuit as to shift the anode-current anode-voltage characteristic of the valve to such a position that the straight part thereof, or the tangent thereto at the operating point, passes through the origin. In setting up the circuit, the resistance R1 is adjusted until the meter reading does not change as the supply voltage varies, and the grid bias is then adjusted at R4 until the meter reads zero. Fig. 11 shows a modification in which the valve V and its cathode resistor R form separate arms of the bridge, and the meter M is connected between the valve cathode and the junction of the other resistance arms R1, R2. The grid is biassed from a potential divider R9, R10 shunted across a neon tube N which is connected in series with a resistance R7, across the supply source. The neon tube applies a constant voltage across the variable resistance R8 and the bridge resistance R2, and the resulting additional current through R2 is independent of supply voltage changes. By adjustment of the resistances R1, R8, the bridge may be set so as to balance despite supply voltage fluctuations. In a further modification, Figs. 8 and 10 (not shown), a neon tube is connected in series with a variable resistance between the positive supply terminal and the junction of the resistance arms R1, R2. When a thermistor is used as the non-linear device, the bridge may be used as a thermometer, the meter M indicating the temperature around the thermistor.

Title: Conversion of plastic organic substances into granular form
IPC: C08J3/16
Filed: 1959-02-18
Abstract: A water-insoluble cellulose derivative or a water-insoluble synthetic resin is formed into spherical particles by dissolving it in an organic solvent which is substantially immiscible with water to form a viscous lacquer, suspending bodies of the lacquer in an aqueous liquid suspending medium, said bodies having a minimum average diameter in excess of 0,070 inch such that, after they have subsequently been rounded and the solvent has been removed from them, the resulting spherical particles will have a minimum average diameter of at least 0,070 inch, maintaining said bodies in suspension until they assume a spherical shape, removing the solvent from the suspended bodies, and separating the particles from the suspending medium.  A solute is initially dissolved in the aqueous medium to provide a solution having substantially the same density as the lacquer and, during the solvent removal stage, additional solute is added to the aqueous medium continuously or at intervals at a rate sufficient to maintain the density of the aqueous medium substantially equal to that of the lacquer globules while the latter are continuously increasing in density due to the removal of solvent therefrom. The solute may be sodium sulphate, magnesium sulphate, barium nitrate, sodium nitrate, aluminium sulphate, sodium chloride or sugar.  The solvent may be removed from the lacquer globules by heating the suspension, or by bubbling air through it, or by adding a considerable excess of water to the suspension.  A protective colloid such as glue, gum arabic, gum tragacanth or starch is preferably present in the aqueous medium.  The synthetic resin may be polyvinyl chloride, polyvinyl acetate, a vinyl chloride-acetate copolymer or polystyrene, and the cellulose derivative may be nitrocellulose, cellulose acetate butyrate or ethyl cellulose.  Specification 815,788 and U.S.A. Specification 2,160,626 are referred to.
