Abstract: 917,156. Rotary spraying-apparatus. AMCHEM PRODUCTS Inc. July 15, 1959 [Aug. 8, 1958], No. 24299/59. Class 69 (3). Liquid-spraying apparatus, e.g. for aerial spraying of herbicidal compositions, comprises a rotatable hollow spray head 12 having at least one spray nozzle on its periphery, the head containing a valve member per nozzle situated immediately behind each nozzle and spring-biased valve-actuating mechanism adapted to retain the valve member in the fullyopen position or, in coaction with centrifugal forces, to retain the valve member in the fullyshut position. The head is rotatably mounted on a bearing 42, 44 at the end of a tube 40 and is driven through gears 50 and 48 by an electric motor 54 whose speed is controlled by a rheostat. The valves are controlled by operation of a lever 88 which, by means of a shaft 78, a sleeve 90 and a grooved collar 111, operates link systems 114, 116 which move rods 136 carrying the valves, the sleeve 90 being connected to the shaft 78 by a ball-and-socket joint so that it is rotatable with the head. Each rod 136 slides through fixed brackets 140 and 122, the link 114 being pivoted to a spring- loaded bracket 138 secured to the rod, the link 116 being pivoted to the fixed bracket 122, and the links being pivoted to each other at 113. In the position shown in Fig. 1, the collar 111 is in its upper position and each valve is held shut both by the action of its spring 148 and by centrifugal force acting on the links. On depressing the lever 88, the collar is pushed into its lower position and the link system is pivoted by the collar into the position shown in Fig. 3 to open the valve. The valve is held in the open position by the spring 148 and also by centrifugal force acting on the links in their changed position. Liquid is fed to the head 12 through a conduit 70 and down through the tube 40 and the feed may be controlled at its source by a solenoid valve. By adjusting the speed of the electric motor 54 the width of the spray swath can be varied. A head having valves which can be operated separately and a head in the form of a tube bearing a single nozzle are also referred to.

Title: Improvements in machines for making nails, bolts, screws and other headed rod
IPC: B21G3/20
Filed: 1958-07-29
Abstract: 900,709. Making rails, bolts and the like. MELD, L. C. July 28, 1959 [July 29, 1958 (2)], Nos. 24363/58 and 24364/58. Class 83 (4). A machine for making nails, bolts, screws and the like from continuous wire stock 35 comprises stock grippers 32 carried by a pair of rams 30, 31 which are moved relatively to each other for causing the grippers to grip the stock and then advance together forcing a projecting end of the stock against a heading tool 40 to form the head, the rams being then moved relatively for releasing the stock and then retracted together whilst the stock is held by a non-return mechanism 34, and a pair of cutters 41 are advanced towards the stock axis to sever the headed article. The rams 30, 31, Fig. 2, are displaceable in a main cylinder 21 supplied with oil at low pressure from a reservoir 16, Fig. 1, by a motordriven pump 11. Inner ram 31 carries collet jaws 32b co-operating with a conical surface 30b on outer ram 30. Wire stock 35 passes through a straightening device 12, the non- return mechanism 34 and inner ram 31 to the jaws 32b. On the heading stroke a piston 26 in cylinder 23 is first moved by cam 17b to pressurize the oil between ram pistons 31a, 30c which close the jaws 32b on to the stock. Piston 27 is then actuated by cam 17a to pressurize the oil on the right of piston 31a, whereby both rams are advanced together and the head is upset against stationary tool 40. Piston 26 is then retracted causing release of jaws 32b, the stock being held against tool 40 by mechanism 34. Piston 25 is then moved by cam 17c to retract both rams whereby transverse cutters 41 carried by ram 31 are moved in stationary cam tracks 43 to sever off the nail length. As the cutters engage the stock, a ram extension 31d engages the non-return mechanism 34 causing it and the stock 35 to be moved rearwardly along the bed at the same speed as the cutters. An ejector 45, Figs. 3, 4 (not shown), carried by the outer ram is moved by a stationary cam track to eject the nail from the jaws. The cams are mounted on a shaft 17 driven through belts 18 by a motor 14. Pressure relief valves 22d, 23d, 24d are provided. The tool 40 may be adjusted axially and two such tools may be mounted for transverse movement whereby the head is upset in two stages. A number of nailforming units may be mounted around a common cam-shaft 17 or one pair of rams may support and actuate a plurality of collet and cutter assemblies and their corresponding non- return mechanisms. In this case the rams are displaced laterally from the axis of the stock. Alternatively, the rams may be operated pneumatically or mechanically.

Title: Boron hydrocarbon polymers
IPC: C08G79/08
Filed: 1959-07-16
Abstract: High molecular weight boron hydrocarbons are prepared by reacting acetylene, methyl acetylene or 1, 3-butadiene with a diborane, N-triethylamine borane or a boron compound obtained by reacting sodium borohydride with boron trifluoride-diethyl etherate.  The methyl acetylene may be introduced in the form of propargyl chloride. The use of a di- or polyolefine with an addition compound of boron hydride and a tertiary amine is specifically excluded.  A solvent which may be tetrahydrofurane, diethyl ether, diethylene glycol dimethyl ether, toluene, xylene, benzene or an excess of one of the reagents may be present in the reaction mixture.  Temperatures may vary from room temperature up to a temperature below that at which reactants are decomposed.  In examples (1) Acetylene is passed through a suspension of sodium borohydride in tetrahydrofurane. Boron trifluoride etherate is added dropwise with stirring and cooling to keep the mixture below 40 DEG C.  After standing, product is filtered and solvent distilled off in vacuo.  The white wax-like product contains 11,5% boron. (2) Sodium borohydride in diethylether or tetrahydrofurane is reacted with boron fluoride etherate to give diborane which is conveyed by an inert gas (e.g. argon) to a second reaction vessel containing tetrahydrofurane through which acetylene is being passed.  The product has a composition [B-C2H3)3]x.  Ex. (3) is similar but uses an excess of diborane and produces a polymer containing groups with the formulae [B(C2H3)3] and [B2(C2H4)3].  In Example (4) N-triethylamine borane [(C2H5)3 N:BH3) is reacted with acetylene.  Triethylamine and residual amine borane are removed in vacuo, leaving a solid residue which liquefies in air with evolution of heat.  It contains 10,1%B. (5) N-triethylamine borane is reacted with propargyl chloride.  (6) N-triethylamine borane is reacted in toluene with acetylene under pressure. (7) 2 vols. of diborane are reacted with 3 vols. of butadiene in tetrahydrofurane until reaction is over.  The mixture is refluxed and solvent distilled off.  A mixture of oily and solid products is obtained.  Uses:  The products are not spontaneously inflammable.  They can be used as high-energy propellants in a solid or pasty state.  Specifications 877,936 and 880,212 are referred to.  Reference has been directed by the Comptroller to Specifications 877,936 and 880,212.

Abstract: 782,954. Electric clocks and watches. ETABLISSEMENTS E. JAEGER. Aug. 29, 1955 [Sept. 2, 1954], No. 24767/55. Class 139 In an electric timepiece the oscillations of the balance staff 5, Fig. 34, are maintained by the interaction of a coil 3 carried by the staff and a magnetic field, the coil being carried by a non-metallic frame 4. The fixed permanent magnet 6 having poles 8, 9, Fig. 35, is associated with a similarly shaped soft iron plate 10, Fig. 34. The maintaining circuit is closed at each swing of the balance by a pin 12 which meets a flexible contact blade 14. The spindle 5 drives the gear train through lifts 17 and a pinion 18. The magnetic field may be produced by two rectangular magnets arranged as shown in Figs. 1 and 2 to allow the coil C to oscillate therebetween. Ring magnets may be used and if desired such magnets may be provided with soft iron pole pieces P<SP>3</SP>, P<SP>4</SP>, Fig. 10. When the invention is applied to watches the magnetic field is obtained from a permanent magnet formed by a broken ring A<SP>3</SP>, Fig. 21 having end poles of opposite polarity and carrying soft iron pole pieces P<SP>13</SP>, P<SP>23</SP>, Fig. 22a, which support the balance staff and between which oscillates the coil C, Fig. 21. The pole pieces may be angled as shown in Fig. 29a. In another embodiment the permanent magnet comprises a broken ring the ends of which constitute poles of the same polarity and which has an intermediate pole of opposite polarity. The similar poles Fig. 31 are interconnected by a soft iron pole piece P<SP>15</SP>. A soft iron member J extends from the intermediate pole and ends in a rectangular part P<SP>25</SP>which with pole piece P<SP>15</SP> serves to support the balance staff. The minute hand shaft passes through the hole T<SP>1</SP>. In another embodiment Figs. 33a, 33b the magnetic field is formed by two flat ring magnets A<SP>1</SP>c, A<SP>2</SP>c. The coil C oscillates between the pole pieces P<SP>17</SP>, P<SP>18</SP> and the rings are connected by a rod M. In the above embodiments the circuit closure means may comprise a pin g, Fig. 20, oscillating with the balance staff and on every swing meeting a rod Á projecting from a rotary insulating cylinder W carrying two contacts w' w<SP>2</SP> which co-operate with a resilient contact blade K<SP>2</SP>. The impulse is given to the balance as it passes through the equilibrium position. The magnetic field may be obtained from an electromagnet E of the kind shown in either Fig. 12 or Fig. 15. In the latter a yoke Q closes the magnetic circuit. The appropriate phase relationship between the current of the electromagnet coil and that of the oscillating coil is obtained by suitable capacitor and/or inductance circuits, Fig. 17-19 (not shown).
