Title: Improvements in or relating to lubricating grease
IPC: C10M169/00
Filed: 1955-04-13
Abstract: A lubricating grease comprises an oleaginous liquid lubricating base thickened to a grease consistency with 5-20 per cent of indigo and 5-20 per cent of a sodium or lithium soap of a fatty acid containing 12-16 carbon atoms in the molecule, the percentages being based on the weight of the composition.  The lubricating base may be an oil of mineral, vegetable, animal or synthetic origin.  A suitable synthetic lubricating base is a complex ester formed by reacting a dibasic aliphatic acid with a glycol and end-blocking the reaction product with a monohydric aliphatic alcohol or a monocarboxylic aliphatic acid, and such a complex ester may be used in admixture with mineral oil.  The fatty acid may be lauric, myristic or palmitic acid and the soap may be formed in situ by saponifying fatty acids or their glycerides in the presence of mineral lubricating oil.  The lubricating grease may be acid, neutral or alkaline and may contain additional ingredients such as oxidation inhibitors, corrosion inhibitors, tackiness agents and extreme pressure agents.  Suitable oxidation inhibitors are diphenylamine, a - or b -naphthylamine, p-phenylene diamine and N,N1-diphenyl-p-phenylene diamine.  The lubricating grease may also contain tricresyl phosphate, or additional thickening agents such as other soaps and other finely divided solids.  In the examples lubricating greases are described consisting of (a) mineral lubricating oil, a complex ester (prepared by reacting together 2 mols. of sebacic acid, 1 mol. of 2-ethylhexane-1,3-diol and 2 mols. of 2-ethylhexanol), indigo, sodium or lithium myristate, N,N1-diphenyl-p-phenylene diamine and tricresyl phosphate; and (b) mineral lubricating oil, ditridecyl azelate, indigo, sodium myristate, N,N1-diphenyl-p-phenylenediamine and tricresyl phosphate.  For comparison purposes, lubricating greases are described similar to (a) above but wherein the indigo or the soap is omitted or wherein the indigo and soap is replaced by carbon black or a mixture of carbon black and sodium myristate.

Abstract: 591,921. Flash pulverisers. INSTI. TUTE OF GAS TECHNOLOGY. April 30, 1945, No. 10855. Convention date, April 8, 1944. [Class 59] Apparatus for comminuting or disintegrating permeable material includes means for entraining and mixing small particles of the material in a fluid stream and means for instantaneously reducing the pressure during the flow to explode and comminute the particles. High pressure steam from a conduit 10 enters a conduit 13 and passes along to a conduit 15 where it is superheated by gas burners 18. Coal is fed from a source 11 into a hopper 20 from whence the granulated material is picked up by a screw 23 and forced into the conduit 15 ; here it is mixed in with the superheated steam, carried down a conduit 36 and through a constricted nozzle 42 where velocity is - suddenly increased and the pressure instantaneously decreased, thus causing the particles to explode and disintegrate. The final product immediately passes to a cyclone separator 44, the comminuted material, still having exposed active surfaces, falling into a heated reservoir 50 and the superheated steam escaping via a pipe 53 to the atmosphere or via a pipe 55 to a source of low pressure. A conduit 34 ensures a condition of pressure equilibrium in the hopper 20 which may be heated by a gas ring 40 in a jacket 37 and a conduit 16 may be provided to drain any condensate from the conduit 15.

Title: Gyroscope apparatus
IPC: G01C19/00
Filed: 1965-03-16
Abstract: 1,092,344. Gyroscopic apparatus. AMERICAN BOSCH ARMA CORPORATION. March 16, 1965 [July 20, 1964], No. 11038 / 65. Heading G1C. A gyro rotor 44, which is mounted for rotation on a spherical bearing 46 is run up to speed by being driven from a spiral spring 74, the drive being disconnected when the spring has become unwound. The outer end of the spring is anchored to the gyro housing and its inner end is formed with a bent-over portion forming a catch 86. This engages a lip 88 formed in a drive shaft 56 when the spring is tensioned. The shaft 56 is journalled for rotation in bearings 58, 60 and can also slide axially in these bearings. A release leaf spring 124 acts on a nut 102 screwed on to the shaft 56 and urges the shaft to the right in Fig. 1, but with the spring in its wound condition a roller stop 146 engages one edge of the catch 86 to hold the shaft in the position shown in Fig. 1. In this position finger members 66, 68 on a yoke 64 solid with the shaft 56 engage slots 70, 72 in the web 54 of the rotor 44. Thus rotation imparted to the shaft 56 will drive the rotor 44. When the spring has become unwound the catch 86 disengages from the lip 88 and the stop 146 allowing the spring 124 to move the shaft 156 to the dotted line position shown in Fig. 1 and withdrawing the fingers 66, 68 from the rotor 44. During the transmission of the drive to the rotor, the rotor is caged by a flange 161 on a caging shaft 160 which is urged towards the rotor by a spring 162, the shaft 160 being concentric with and mounted in the shaft 56. As the shaft 56 moves to disconnect the drive, the spring 162 causes the flange 161 to stay in contact with the rotor 44 until the finger members 66, 68 have become disengaged from the rotor, before the flange 161 itself moves clear to allow free rotation of the rotor 44. Before use, the wound spring 74 is held from acting on the shaft 56 by a pawl 114 engaging with a recess in the nut 102. This pawl is released by an explosive charge, when required. The spring 124, as it moves to release the drive to the rotor may actuate a switch to signal that the rotor has been brought to speed. The rotor speed may be monitored by a permanent magnet 194 on the rotor co-operating with a stationary pick-off 196. Attitude pick-offs 180, 184 for the rotor are also provided.

Title: Improved heat treatment of steel tyres or wheels
IPC: C21D9/34
Filed: 1934-04-12
Abstract: In the heat-treatment of steel wheels or tyres having a temperature above the critical range, the surface or surfaces of the wheels &c. are cooled very rapidly by means of jets of atomized water so that sufficient evaporation of the water particles is assured, and the amount of water reduced as the surface cools.  The cooling is stopped when the heat retained by the tyre or wheel rim corresponds to an average temperature above 500 DEG  C., but below the critical range and the tyre or wheel is then placed in a heat-insulated container or furnace until the retained heat has evened out to produce the aforementioned average temperature, the tyre &c. being finally cooled slowly.  Where the tyre &c. initially is at a temperature above the critical range, it is cooled until its temperature, or its surface to the desired depth, is just below the critical range.  The tyre &c. is then reheated or the heat in it evened out until its temperature is just above the critical range and it is given the treatment, starting with cooling by jets of atomized water, described above. Specifications 8258/15, 324,686, [both in Class 72], and 406,029, are referred to.

Mine signalling systems; order and order-type apparatus.-In a signalling system wherein the sending of a signal cancels the previous signal, each of the receiving devices is provided with a relay having an operating coil and a retaining coil or a single coil serving both purposes. In the common return of the operating coils is connected the coil of a switch placed in the common return of the retaining coils, said switch being momentarily opened to break the retaining circuit of the previous signal and again closed to retain the new signal. In the arrangement shown in Fig. 1, each of the lamps D or other visual indicators is controlled by a relay E having an operating coil F and a retaining coil G. In the common return of the operating coils F is connected a switch coil N and a single stroke bell S. The armature 0 of the coil N operates a switch Q, Q<1>, in the common return of the retaining coils G, through a pawl O<2> and a star-wheel P. The switch Q, Q<1> is normally closed, but as a tooth of the wheel passes from under a block Q<4>, the switch is opened until the next tooth of the wheel engages the block Q<4>. The momentary opening of the switch Q. Q<1> breaks the circuit of the retaining coil and lamp of the previous signal, while the closure again establishes the circuit for retaining coil and lamp of the new signal. The signal circuits are controlled by switches C, and a clearing switch R is placed in the circuit of the retaining coils. The windings F and G may operate separate linked armatures. The switch Q. Q<1> may be operated by a pivoted member O<2>, Fig. 3. which rides over the projection Q<4> to open the switch when the magnet N is energized but which swings about its pivot O<3> when the magnet N is de-energized in order that it may not operate the switch. The switch is provided with carbon arcing contacts Q<2>, Q<3>. In the modification shown in Fig. 2. each relay E is provided with a single coil F' and its operative circuit closed by a switch C, while its retaining circuit includes a battery B and the contacts L, L<1> and Q, Q<1>.
