Title: Improvements in Warp Uniting, Warp Drawing-in and like Machines.
IPC: D03J1/14
Filed: 1917-08-02
Abstract: 110,139. Barber & Colman, and Bingham, T. E. Aug. 2, 1917. Healds and reeds, threading; warp threads, uniting.-In warp drawing-in, uniting, and like machines, the tension on the threads about to be operated upon is increased by deflecting the threads on the edge of a disk brought into engagement with the threads by the relative movement of the threads and a support on which the disk is rotatably mounted. The invention is described as applied to the drawing-in machine described in Specification 111,387 and comprising a carriage c adapted to be traversed across the machine and the sheet of warp threads a, which extend from the warp beam to a suitable clamp, and carrying the thread selecting, separating, and threading means. A disk f is rotatably mounted on the carriage, so that the threads a are forced against the edge of the disk to one side of its axis, as the carriage is traversed, and are deflected around the edge. The additional tension placed on the threads facilitates the action of the selecting-finger g and prevents or minimizes bunching of the threads. The disk may have its edge roughened or serrated and may be of any desired diameter.

Abstract: 126,208. Moore, Sir A. G. H. W., and Wilson, W. G. July 8, 1918. Compulsory differential driving; change-speed gearing. - T h e driving-shaft of an endless-track vehicle is fitted with compound epicyclic gears which operate the countershafts carrying the track-driving sprockets and can be braked to vary the speed of the countershafts relatively to each other and to their common driving-shaft. The engine shaft c drives a shaft b through a reversing-gear d, each end of the shaft b carrying a compound epicyclic gear, one gear-train comprising a sun-wheel g, planet pinions i mounted on a carrier on one of the sprocket-carrying countershafts a, and an internal gear k on a, brake-drum l. The second gear train comprises a carrier h carrying an internal gear meshing with planet pinions m on the brake-drum l, the planet pinions gearing with a sun-wheel n mounted on a loose sleeve carrying a second brakedrum o. By braking the drum l, the drive is through the sun-wheel g, pinions i, and carrier j. When the drum l is free and the second drum o is braked, the drive is through both sets of gears, thus giving a second speed ratio. In a modification, the planet pinions m are mounted on the outside of the brake-drum l and mesh with an internal gear on the second brake-drum o and with a sun-wheel on the shaft b.

Title: Portable electric power outlet-socket extension
IPC: H01R25/00
Filed: 1974-05-03
Abstract: 1464379 Outlet-socket extension R C DAVIES 3 May 1974 [8 March 1973] 11302/73 Heading H2E A portable electric power outlet-socket extension comprises a stand 1 which rests on its base 2 and has a stem 3 extending upwardly from the base, a three-pin electric power outlet-socket 4 mounted on the stem, a three-pin electric power plug 6 and a flexible electric lead 5, terminating at the plug, having three wires connecting the terminals of the outlet socket to the corresponding terminals of the plug, the lead passing into the interior of the stand through an entry 8 in the base or in the lower part of the stem adjacent to the base. Preferably the force required to withdraw a plug from the outlet-socket is less than the weight of the stand. The part of the base opposite the stem may be convex, and the base may be weighted so that the stand is self up-righting. A drum, which may be spring loaded, may be in the base of the stand on which the lead is wound. An off-centre pivoted nylon grommet fitted at the point of entry 8 allows the lead to be clamped and the effect of the spring loaded drum halted at any point of the lead. The stem may be rigid, adjustable in length, telescopically for example, and can have a plurality of outlet-sockets mounted on it with like terminals connected in parallel. A clip or hook may be provided on the stem adjacent to the outlet-socket to park the plug of an appliance when not in use. The stand is intended as an aid to invalids, &c. eliminating the need to bend to insert or remove plugs from the sockets normally at or near floor level. Removal of a plug provides greater safety than relying on a switch on an appliance. Suitably, the socket plug and outletsocket are rated to a maximum capacity of 13 amps.

Title: Improvements in or relating to mass spectrometry
Inventor: HAZELBY DAVID
IPC: H01J49/16
Filed: 1969-04-30
Abstract: 1,246,709. Ion sources. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 30 April, 1970 [30 April, 1969; 10 March, 1970], Nos. 21976/69 and 11451/70. Heading H1D. [Also in Division G3] A method of ionizing a material and introducing the ionized material into a mass spectrometer comprises the steps of dissolving the material in a solvent, passing the dissolved material and solvent through a region of electric stress sufficiently high to ionize the material, evaporating the solvent, substantially separating the ionized material from the solvent and introducing the ionized material into the mass spectrometer. Material to be analyzed, which may be compounds with a very high molecular weight, such as proteins and polymers, highly polar compounds of lower molecular weight, or lower molecular weight compounds which are unitable, is dissolved in a solvent, e.g. a mixture of benzene and acetone, acetone alone, ethyl ether, methanol, ethanol, a mixture of 75% ethanol and 25% water, butyl alcohol, or nhexane, and passed through the tip 14 of a hollow needle into a region of high electric stress produced, e.g., by maintaining the needle at a potential of 6 kv. relative to earth at a polarity appropriate to that of the ions to be produced. Charged droplets emerging from the tip 14 expand, thus aiding evaporation of the solvent. Evaporative cooling which would hinder the loss of solvent, is prevented by heating the droplets by a gas, e.g. nitrogen or air, contained in a housing (not shown) secured to the end flange 46 of the source unit of a mass spectrometer. The ions formed are attracted to and focused on the orifice 22 of a nozzle 20 by an apertured plate 16, and then pass through a nozzle 24, earth plate 28, two pairs of deflecting plates 32 and 34, and a focusing lens system of three apertured plates 36, 38 and 40 to the mass spectrometer. Pipes 23 and 27 are connected to a roughing pump and a diffusion pump respectively. Plates 36, 38 and 40 may provide further acceleration of the ion beam which may be further ionized inside the mass spectrometer, e.g. by a transverse electron or photon beam. An alternative embodiment (Figs. 3 and 4, not shown) employs a part-spherical plate 16 and a modified nozzle arrangement of two divergent nozzles and a thin electrostatic lens. The droplets are heated by a Nernst filament. In a further alternative embodiment (Fig. 5, not shown) the dissolved material is sprayed into an evacuated chamber and is heated by radiation entering the chamber through a collimation slit and an optical lens system from an external Nernst filament provided with an automatic temperature control system (see Division G3) incorporating photo-cells. The radiation may alternatively be provided by a laser beam.

Title: Vacuum pump
IPC: H01J41/20
Filed: 1963-03-22
Abstract: 1,031,766. Ion pumps. STANDARD TELEPHONES & CABLES Ltd. March 22, 1963 [March 29, 1962], No. 11477/63. Heading H1D. In a vacuum pump arrangement comprising an ion pump and a backing pump for scavenging gas from a low potential region of the ion pump, the ion pump has electron emissive surfaces 2 and 3 generating electrons which are accelerated and focused by anode portions 16 and 17 towards a central region in which a point 40 of minimum potential surrounded by a region of maximum potential is established. Gas entering at 26 is ionized, and ions which acquire energies sufficient to carry them over the said potential maximum pass through further positive potential electrode pairs 14 and 13 to a low potential region in a chamber 6 from which they are scavenged by a backing pump connected to outlet 27. A cold cathode of tungsten or rhenium may be used in conjunction with cathodes 2 and 3 to augment the electron current. Alternatively, the cathodes 2 and 3 may be secondary electron emissive so that a radiofrequency potential applied through a coil 37 to anode portions 16 and 17 will produce multifactor action between the cathodes 2 and 3. Electrodes 13, e.g. of platinum, are connected to a metal coating 12 in the chamber 6 if the latter is of glass or ceramic. Electrodes 14 may be bridged by a metal mesh 18. Cathodes 2 and 3 may be of stainless steel or beryllium copper which in addition to being secondary emissive will also getter any ions formed in their vicinity. Additional focusing rings 30 and 31 may be provided.
