Title: Stable solutions of aryllithium compounds and improved methods of producing same
IPC: C07F1/02
Filed: 1963-01-29
Abstract: Stable solutions of aryl-lithium compounds are made by treating a suspension of the aryl-lithium compound in a hydrocarbon with an ether in amount sufficient to give a solution and not more than twice said amount.  Alternatively, a finely divided suspension of Li metal, which may be in a mineral oil, is provided in a mixture of a hydrocarbon and sufficient ether to provide a solution, adding a haloaryl compound thereto and filtering off the lithium halide to give the desired solution.  In a preferred embodiment, after filtering off the lithium halide, the ether may be distilled off, hydrocarbon added and the distillation continued to give a constant boiling solution of 37 DEG  C. at 125 mm. Hg.  A stable solution may also be obtained by adding C6H5Br in heptane to LiBu in heptane, filtering off C6H5Li, suspending the Li compound in C6H6 and adding thereto (C2H5)2O to give a solution.  The Li metal used may contain up to 3 wt. per cent Na.  The hydrocarbon solvents may be from the group C5H12 to C10H22, petroleum fractions, aromatic hydrocarbons and mixtures such as mineral or lactol spirits.  The ether may be diethyl, di-isopropyl or di-n-butyl, tetrahydrofuran or tetrahydropyran. Other aryl-lithium compounds which may be stabilized in solution are those wherein aryl is biphenyl or naphthyl, whilst numerous aryl halides are exemplified including compounds having sulphur heterocyclic rings, arsines and silanes, but the preferred compounds are chloro- or bromobenzene.

Title: Apparatus for recording of electric impulses
IPC: B41J1/00
Filed: 1949-03-11
Abstract: 654,584. Magnetic sound recording and reproducing apparatus. DIAMAND, W. March 11, 1949, No. 3954/48. [Class 40 (ii)] In a magnetic recording and reproducing apparatus in which parallel curved tracks are formed on a moving magnetic strip 1 by means of a plurality of magnetic transducers 7 radially mounted and equally spaced on a revolving plate, the said transducers are so arranged during recording that one transducer is still recording at the end of one track after the next transducer has commenced at the beginning of the next track, both transducers recording at full intensity during the overlapping period. In order to obtain a smooth change-over from one track to another during reproduction, the signal current in one transducer is progressively decreased as the current in the next is progressively increased. The electric connection with the transducers may be by slip rings, and the change-over controlled by electric contacts or relays operated by the rotating disc to produce pulses causing the extinction of current in one transducer while causing the simultaneous appearance of current in the next transducer. The transfer may be effected smoothly by arranging that the said pulses control two pentode circuits, the anode current versus grid voltage characteristic of which are logarithmic, i.e. the output current proportional to the product of two input voltages, the pulse signal being of such a nature as to produce an auxiliary voltage in one circuit causing a proportional extinction of current, and in the other circuit a proportional increase of current. The plate carrying the transducers is provided with teeth 9 engaging a gear-wheel 10 on a worm shaft driving a sprocket 4 which controls the velocity of the tape past the transducers. A lever 17 and an actuating solenoid 21 is provided to enable the tape to be disengaged from the sprocket 4 to allow the tape to run at an increased speed for locating quickly a desired part of the record. The distance of this high-speed travel of the tape may be defined by arranging a reproducing head at the edge of the tape where equidistant markings have been recorded magnetically. The output current from this head may then feed an electronic counter followed by a mechanical counter. A pre-setting arrangement may be provided whereby the counters operate a relay at the pre-set marking and restore the tape to its slow movement automatically, ready to start reproducing.

Title: Deep well pumping apparatus
IPC: F04B47/08
Filed: 1956-02-09
Abstract: 778,489. Rotary motors and pumps. MARSHALL, S..T. E. Feb. 9, 1956, No. 4126/56. Class 110 (2). A deep-well pumping unit 11 comprises two or more gas or hydraulic motors 22, 23 and two or more pumps 26, 27 driven by the motors, motors and pumps being of the outwardly-sliding vane type. The unit is suspended in a well 10 and liquid is sucked up through a strainer 51 passing into a manifold 16 to the pumps, which discharge the liquid into a manifold 17, into which the motors 22, 23 also exhaust their working fluid. The two fluids mix and pass to the top of the well by way of tubing 12. The vanes of both motors and pumps are forced radially outwards by working fluid under pressure passing axially through the rotor 47 to the undersides of the vanes. Driving fluid is pumped from the land surface downwardly through tubing 10 to the inlets 20, 21 of the motors, by way of the manifold 15, entering the motor chambers 62 through ports 66 to drive the vanes 60. At the same time, fluid enters at each end of the rotor 47 by way of by-passes 56 in the motor cylinders and channels 54a of the bearings 54 to equalize the pressures on the ends of the rotor causing the latter to " float " during high-speed rotation. Part of the fluid is recirculated, after being cleaned. Each rotor 47 is provided with flats 69 so that the rotor is hexagonal in shape. The flats relieve fluid which would otherwise be trapped by the vane tips and the working chamber walls. From the pump 26, fluid is bled through an axial passage 77f from which part of the fluid moves through a lateral passage 77g in the rotor 47 into an annular groove 77h (not shown) in the wall of the rotor by way of an orifice 77i (not shown), to lubricate the surfaces between the rotor 47 and the sleeve 76 (not shown). After the manifold casing 11 has been submerged in the fluid of the well, the pump assembly 32 is lowered into the casing by means of a wire with a releasable coupling which engages a carrier 33. The various fluid chambers axially disposed along the assembly 32, are sealed from one another by bosses 35 containing grooves 36 (not shown) for O-shaped packing rings.
