Title: Improvements in sanding gear chiefly adapted for use upon locomotives
IPC: B61C15/10
Filed: 1929-01-28
Abstract: 328,597. Jourdain, M. F. R., and SOC. Freins Jourdain Monneret. Jan. 28, 1929. Sand, distributing on wheel tracks.-A sanding device for locomotives &c. comprises a mechanical propelling device such as a screw conveyer &c. which is driven by a fluid-pressure motor, the exhaust gases from the motor being led into the sand exit conduit to facilitate the discharge of the sand. The motor M, Fig. 1, is supplied with compressed air through a pipe A and drives a screw conveyer 4 which expels the sand from a container 1 into the discharge pipe 2 into which are led the exhaust-gases from the motor through a pipe E. A single-acting motor, Fig. 6, may be employed to drive a ratchet 7 on the shaft of the screw conveyer. An arm 9 on the conveyer shaft contains a pawl 11 and is connected to a piston 13 which moves to the left, when compressed air is admitted to the chamber 29, and returns when this chamber is exhausted, due to the tension of a spring 10 and the pressure of the air on the end of the piston rod 12'. The piston rod is connected by a lost-motion device with a slide valve 15 working in a chamber 21 supplied with compressed air by a pipe 16. This valve controls the supply of compressed air, through a conduit 24, to the underside of a piston 23 actuating a slide valve 26 and also the exhaust from the underside of the piston through a conduit 30 and outlet pipe 17. In the position shown in Fig. 6, compressed air is supplied through conduits 22, 24 to both sides of the piston 23, which is thus balanced, the conduit 28 to the rear of the piston 13 being in communication with the compressed air chamber 21. When the piston 13 moves to the left, the valve 15 connects the conduits 24, 30 to exhaust and the piston 23 with valve 26 is depressed against the pressure of a spring 25. This movement connects the conduit 28 to exhaust and the .piston 13 together with the valve 15 moves to the right. In a modification, Fig. 9, a double-ended piston 13<a>, 13<1a>, operates the ratchet. This piston is double-acting and is operated by a piston valve 23<a>, 23<1>a. Pressure, is admitted to the chamber 21 through conduit 16 and, as shown, flows through the conduit 28<a> to the rear of the piston 13<a>; the rear of the piston 13<1a> and piston valve 23<1a> being connected to exhaust through conduits 22<1a>, 28<1a>, valve 26 and conduit 17. Movement of the piston 13<a> to the left uncovers the conduit 22<a> and admits pressure to the piston 23<a> of the valve which moves to the left to cut off the pressure supply through the conduit 28<a> and connect the latter to the exhaust 17. The conduit 28<1a> is open to the pressure in the chamber 21 and the piston 13<1a> is then moved to the right.

IPC: H01F27/04
Filed: 1963-01-24
Abstract: 1,025,686. Cable terminations. ALLMANNA SVENSKA ELEKTRISKA A.B. Jan. 24, 1963 [Jan. 25, 1962], No. 2975/63. A pothead for connecting an oil-filled cable to a transformer enclosed in a tank so that the cable does not have to be bent close to the tank comprises a core situated in a housing, said housing having an insulator 6, Fig. 1, for entering said tank and a metallic tube 1 which consists of a straight and a curved part, said core consisting of a conical part situated in insulator 6 and a straight and curved part situated in the straight and curved part of the housing, the straight part of the core being adapted to enclose the cable end. The core has voltage controlling foils 14 and metallic foils 13 forming an earthed shielding tape wound with insulating paper strips on a tube 12 made of insulating material and a metallic tube 33. The outermost of foils 14 is preferably extended to be the outermost foil of the metallic foils 13 which are connected together and to tube 1 by earthed element 15. At the conical face of insulator 6 short foils may be inserted between a reduced number of through foils, a good control of the electric flux still being obtained. Metallic tube 1 has a flange 2 for fastening the pothead to the transformer tank, a flange 4 for connection of anchoring means for the cable sheath and armouring, and nipples 5 which connect the housing to the oil system of the cable (not shown). The insulation layers of the cable end are cut away to form connecting plug fitting 16, Fig. 2, for insertion into resilient contact 10 of the pothead. At 17 the cable sheath is cut away and soldered to flange 4 at a point 18 and the cable insulation is increased conically up to 19 where the diameter of the cable is slightly less than the diameter of tube 12. Outside the conical part a shield 20 is arranged which is connected to the earthed shielding tape at the cable 17 and is separated by a small distance from the metallic foils 13.

Title: Improvements in, or relating to, starting switches for use in connection with electric motors
IPC: H01H19/46
Filed: 1936-01-03
Abstract: 467,634. Actuating controllers. CRABTREE & CO., Ltd., J. A., and McLOUGHLIN, H. F. Jan. 3, 1936, No. 3137/37. Divided out of 469,935. [Class 38 (iii)] A star-delta starter is of the type employing two contactor switches for effecting the star and delta connections and for connecting the motor to the supply, and one of the contactors has two sets of fixed and moving contacts, the operating member that connects the moving contacts with the armature of the contactor being associated with a tension spring which functions firmly to hold the moving contacts in their closed star position, but is so controlled by toggle linkage that it imposes no material opposition to the pressure on the other set of contacts when the starter is in the delta position. The contactor comprises movable contacts a2, b carried by members coupled to an operating member e projecting through the base of the magnet casing, the member e extends below the lower contacts a<2> and carries a pair of toggle links g which are accommodated between fixed carrier bars a<1> and have pins g<1> at their outer ends engaging slots d<1> in the bars al. The pins g<1> of the links g are coupled by a spring (not shown) so that when the contactor is de-energized and the contacts a2 engage the fixed contacts a the spring maintains the contact pressure. When the contactor is operated, and the moving contacts b engage the upper fixed contacts, the spring h is strained, but the toggle links g move to their straightened position near their dead centre. Thus the spring applies no material force to open the contacts b, and the hold-on action of the contactor is not resisted.

Title: Improvements in or relating to telephone systems
IPC: H04M3/40
Filed: 1926-02-03
Abstract: 274,922. Samaia, D. Feb. 3, 1926. Telephone systems and apparatus. - A substation is provided with a thermionic amplifier and with key switches whereby the transmitted or the received currents may be passed through the amplifier as desired. An additional amplifier, receiver, and switch-hook may be provided for obtaining two-stage amplification of the received currents. In the arrangement described, normal non-amplified working is obtained when the receiver R is lifted, the circuit of the microphone M being completed over the switch-hook contacts 29, 30, and the receiver R in series with the secondary winding of the induction coil B being connected across a choke I in the line x, y. To amplify the transmitted currents, a key P2 is depressed and at contacts 24, 25 closes the fila. ment heating circuit of the valve A, at contacts 17, 18 connects a resistance L in series with the receiver R, and completes a circuit 12. 13, 10, 9, 19, 21 through the secondary winding of the induction coil B and the primary winding of the input transformer T1; the amplified transmitted currents through the secondary winding of the output transformer T2 are passed to the line x, y over the circuit 23, 22, 7, 6, x, y, C, 16, 15. To amplify the incoming currents, the key P1 is depressed, the received currents thereby being passed to the input transformer T1 over circuit x, 6, 5, 15, 16, and the amplified currents passing through the receiver R over circuit 3, 2, 22, 23, T2. As long as the key P1 is held down amplification of the transmitted current is prevented but non-amplified currents may be sent to line over circuit x, L, 17, 18, 8, 9, 19, 21, 12, 11, 33, 34, resistance L1, C, y. There is a mechanical connection between the switch-hook G and the key P2 whereby the latter is automatically restored when the receiver is hung up. If it is desired to amplify the received currents in two stages, the auxiliary receiver Ra is removed from its hook Ga, thereby bringing into operation the auxiliary amplifier A1, the input circuit of which is connected across the normal receiver R : the transmitting circuit is opened at this time at contacts 33, 34. The arrangement of the parts constituting the amplifying apparatus is described in the Specification. They may be incorporated with the existing apparatus or may be placel in a. separate box.

Title: Improvements in or relating to film distillation
IPC: B01D3/12
Filed: 1947-02-04
Abstract: <PICT:0635906/III/1> Liquids are submitted to evaporative distillation by causing the heated liquid to flow downwards in the form of a film over a stationary surface, which is not heated other than by contact with the liquid, in close proximity to but out of contact with a condensing surface; the pressure between the two surfaces being maintained less than the vapour pressure of the heated liquid. The method relates particularly to short-path distillation. In a preferred embodiment, the vaporizing surface is a vertically-disposed plate which may be fluted or corrugated; and both sides of the plate are simultaneously used to guide a film of the heated distilland.  The condensing surface may be a cooled, solid surface or may be one or more double-surfaced films of cold liquid flowing downwards between vertical guide-rods.  A viscous hydrocarbon oil is pumped through heater 13 where the temperature of the oil is raised to 350 DEG  F.; it is then degassed in vacuum chamber 15 and supplied to the upper section of chamber 1, a constant head of heated oil being maintained on partition 3 by regulating the rate of pumping.  The oil passes through apertures 4, which stretch across a diameter of the partition, on to the top edge of plate 5, and flows down the plate as a film.  Chamber 1 is maintained at 10 to 15 microns pressure by means of a pump connected through pipe 10.  Part of the oil vaporizes and then condenses on the walls of the chamber, which are cooled by circulating a cooling medium through jacket 2. Three annular troughs 6 are provided for collecting three condensate fractions, and these may be withdrawn either individually or as one stream. The unvaporized oil collecting in the base of chamber 1, is withdrawn through pipe 18, and may be recycled if necessary. Instead of one plate 5, several plates may be used and disposed so as to form a circle, square or rectangle.  In another modification, four parallel plates alternating with three sets of rods for guiding direct-contact, condensing liquid, are used.  The strength of the vaporizing film may be increased by adding agents to reduce the surface tension.  The distillation of petroleum distillates, lubricating oils, residuums, petrolatum, wax, acids, and oils containing soaps, is referred to.  Also of animal and vegetable oils, fats and waxes; resins; sulphuric acid; phosphoric acid; and decomposable inorganic salt solutions.  The separation and purification of hormones, vitamins and enzymes from fish and vegetable oils, and the separation of sulphuric or phosphoric acid from hydrocarbons are referred to.

Title: Improvements in the manufacture and production of phosphoric acid esters
IPC: C07F9/11
Filed: 1929-01-31
Abstract: 330,228. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 31, 1929. Phosphoric acid esters are produced by mixing a primary aliphatic alcohol or an aromatic alcohol or a phenol with phosphorus oxychloride at about 0‹ C., and then warming to a temperature below that at which the bulk of the hydrochloric acid is evolved (30-60‹ C.), if desired under reduced pressure. In a modification, insufficient alcohol (or phenol) to esterify completely the phosphorus oxychloride is first added, and then the same or a different alcohol (or phenol) is added, preferably in excess, in order to complete the esterification. The hydrochloric acid is removed by washing with water or dilute alkalies, and the ester is distilled under reduced pressure. Examples are given of the preparation of tributyl phosphate, n-butyl-di-isoamyl phosphate, di-isoamyl-cyclohexyl phosphate, and phenyl-dibutyl phosphate. Specifications 300,044 and 328,963 are referred to.

Filed: 1946-01-02
Abstract: 610,081. SAW-tooth amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 2, 1946, No. 3364. Convention date, May 30, 1942. [Class 40 (vi)] In a circuit for deflecting a cathode-ray beam, comprising a pair of series-connected deflecting coils, the non-uniform distribution of capacity across the coils which causes them to resonate at a number of different frequencies is rendered substantially ineffective. As shown in Fig. 1, a diode 40 is used to suppress the parasitic oscillations due to the coil 25 resonating with the non-uniform distributive capacity 32, the lower frequency parasitic oscillations due to the coils 24, 25 in series resonating with the distributive capacity 30 are suppressed by the diode 34 as described in Specification 566,835. Resistance 42 limits the diode current flowing in coil 25 at the start of each deflection cycle. In a modification, Fig. 2 (not shown), a tightlycoupled choke coil is connected in parallel with the deflecting coils having corresponding points of the choke coil and deflecting coils connected so that the reactances ratios between such points are maintained equal. By this means all sections of the deflecting coils are effectively inductively coupled, thus reducing the effect of the non-uniform distribution of inductance and capacity in the deflecting coils. Alternatively, the distributed capacity 32 across coil 25 may be balanced out by using an auxiliary capacity across coil 24, Fig. 3 (not shown), this capacity being adjusted until the scanning defects are reduced to a minimum.
