Patent GB-987639-A (GB)
Title: Means for reducing the noise generated by electrical transformers
Inventor: TURNER DAVID LILLEY
IPC: G10K11/16
Filed: 1962-01-29
Abstract: 987,639. Transformers. BRUSH ELECTRICAL ENGINEERING CO. Ltd. March 25, 1963 [Jan. 29, 1962], No. 3319/62. Heading H1T. The noise produced by a transformer core may be reduced by a thin " pneumatic " barrier positioned around the core such that, in the locality of the limbs, it passes between the core and the windings. The barrier has a low density compared with that of the liquid in which the transformer is immersed, since it comprises either a rigid casing, a flexible membrane formed into a closed bag, or a cellular body, filled with a selected gas, the walls being impermeable in each case. In the latter case, the cellular body is formed from a soft framed plastic, the cells of which are mainly non-interconnecting, and has imperme able membranes on its surfaces. The gas, which may be sulphur hexafluoride or fluoropropane, or another gas with high dielectric strength, is under pressure to prevent the cellular body collapsing under the hydrostatic pressure of the transformer oil. Both types of barrier may be provided with openings or gap to allow for the passage of a coolant or of supporting members. If the heat produced by the core is not excessive, the core may be enclosed completely in a gas container.

Void [Published under Sect. 91 of the Acts]. [Class 36.] In laying electric cables in conduits, the cables are rested on small insulating supports arranged in the conduits and an insulating compound is poured around the cables to fill the conduit. In the construction shown, a cable 3 is supported in the centre of a conduit 1 on bands 5 of asbestos or other insulating and incombustible material, attached to the limbs 8, 9 of a metal frame 4 adapted to engage the walls of the conduit. In order to remove all moisture from the conduit before it is filled with compound, a combustible material which leaves no harmful residue after combustion may be burnt in the conduit. An asbestos wick 7, soaked in a combustible liquid, may be ignited in the conduit immediately before pouring in the compound, the wick being withdrawn after combustion. A concave cover 2, Fig. 3, is placed over the conduit whilst the compound is still plastic, a portion of the compound 6 being forced out under the cover and forming a seal 11 between the exterior walls of the conduit and the edges of the cover.
Patent GB-491648-A (GB)
Title: Improvements relating to diesel fuels
IPC: A43D1/00
Filed: 1937-02-05
Abstract: Diesel fuel with a low ignition temperature is produced by treating a heavy petroleum oil of the Diesel type with a nitrating agent under such conditions of amount, concentration, temperature and time that a fuel of low ignition point is obtained with a minimum of sludge, the residual nitrating agent and acidic matter being removed after nitration.  The nitrating agent is preferably nitric acid diluted with water, or a mixture of sodium nitrate and dilute sulphuric acid. The sulphuric acid sludge from petroleum refining processes may be used.  Phenolic bodies may be removed from the Diesel oil prior to nitration, e.g. by treatment with an aqueous alkaline solution or by solid alkali.  A nitration catalyst such as aluminium nitrate may be present in the nitrating stage.  An oxidation inhibitor such as a -naphthol may be added to the nitrated oil.  An auxiliary primer consisting of nitrated semi-solid or solid petroleum fraction may be added to the nitrated oil.  These auxiliary primers may be extracted from the starting materials of their manufacture by a selective solvent such as aniline.  In an example, five volumes of Colombian Diesel oil was given an addition of one volume of nitric acid of sp. gr. 1,09 and stirred for 11 hours at 70 DEG  C.  About 1 per cent of sludge was formed during nitration and the sp. gr. of the oil changed from 0,850 to 0,870.  The nitrated product possessed a cetane number of 67 as compared with 44 for the untreated oil. Nitrogen determination showed that the treated oil contained 0,42 per cent of N as compared with 0,008 per cent in the untreated oil.  Several further examples are given.  British Specifications 359,994 and 379,725, U.S.A. Specification 1,820,983, and German Specification 574,678 are referred to.

Title: Gear pump
IPC: F04C15/00
Filed: 1972-01-26
Abstract: 1372481 Rotary positive-displacement pumps SUNDSTRAND CORP 26 Jan 1972 [27 Jan 1971] 3569/72 Heading F1F In a gear-pump with pressure-loaded plates 43, 44 abutting the gears 18, 20, each plate has recesses 50 through which pressure is transmitted from the tooth spaces to a chamber 52 between sealing members 54, 55 and communicating with an outlet chamber 49. To enhance the pressure balance each plate has apertures 57 near to an inlet chamber 48 and through which pressure in the tooth spaces is transmitted to chambers surrounded by sealing rings 58, rapid pressure changes in said chambers being obviated by grooves 57a on the gear side of the plate. To minimize leakage between the recesses 50 and the inlet chamber each plate has bevelled edges 125, which are partially flattened when the plate is forced against a housing member 12 by fluid-pressure. Bearing sleeves 34 are lubricated by a proportion of the working fluid trapped between the meshing teeth escaping to the inlet chamber by way of a groove 60 and annular channel 61 in each plate, grooves 35 in the sleeves, passages 64, 65, another annular channel 68 and a recess 69 in each plate. This arrangement reduces jarring, and thus noise too, and is described in greater detail in Specification 1372482.

Abstract: 716,262. Lubricating pumps. AUTO RESEARCH CORPORATION. Feb. 12, 1952 [Feb. 13, 1951], No. 3724/52. Class 102 (1). [Also in Group XXXIV] A lubricating pump C and its actuating mechanism are carried by the cover A of a lubricant reservoir and the pump and part of the drive gearing are carried by a depending frame B and the rest of the drive gearing and a horizontal drive shaft 29 are carried above the cover. A lever 55, fitted with a pawl 80, drives a ratchet wheel 34 on the shaft 29 which also carries a holding ratchet wheel 56 cooperating with a pawl 58. The shaft 29 carries a worm 61 driving a worm.wheel 64 on a vertical shaft 65 fitted at its lower end with a worm 97 driving a worm wheel 101 on a shaft 102. The shaft 102 drives a disc 105 that has a cut-away portion 137 that co-operates with a pin 108 to drive a cam 107. A lever 117 is pivoted at 118 to a support 115 and carries a roller 119 engaging the cam 107 and is provided with an enlargement 122 that engages a shoulder 125 on the pump piston 129 and an abutment 124 for a spring 152; a further enlargement 123 cooperates with abutments 149, 150 on a manuallyactuated rod 145. The suction stroke of the pump is effected by the cam 107 and as the roller passes over the peak 138, the cut-away portion 137 of the disc 105 permits free movement of the cam so that the spring 152 can effect a quick delivery stroke. The support 115 of the lever fulcrum is adjustable by a nut 155 to vary the stroke of the pump. The pump inlet is fitted with a filter 133 and the delivery is divided to two fittings 175, 176, one which is connected to the outlet 190 and the other to a metering unit 186 which supplies the bearing 28, the excess lubricant returning through opening 188 to the reservoir. The outlet 190 is connected to an installation which has a metering unit at each point to be lubricated. The lever 55 is oscillated by a connection to a reciprocating or rotary element of a machine to be lubricated.
