Title: Improvements in and relating to the Lubrication of Thrust Bearings.
Inventor: PARSONS CHARLES ALGERNON
IPC: F16N7/36
Filed: 1916-02-16
Abstract: 103,867. Parsons, Sir C. A., Cook, S. S., and Douglas, L. M. Feb. 10, 1916. Channels in thrust bearings.-In a thrust bearing for shafts consisting of a number of fixed and rotating collars a, b, lubricant is admitted through radial passages c to recesses g near the roots of the rotating collars b, and passes outwardly through inclined grooves h in the working faces of the stationary collars a, the outward flow being accelerated by the rotation of the collars b. The grooves h are inclined in both directions and may terminate in a circular channel k, which allows the lubricant to escape freely and prevents the formation of ridges in the face of the collar a due to wear. If the collars a are divided for taking thrusts in two directions, the adjacent ends are chamfered as shown in Fig. 5, to prevent the lubricant from being swept off the face of the rotating collar.

[Class 127] Acid is removed from the conversion liquors obtained in hydrolysing starch, cellulose, &c. with acid by treatment with an insoluble condensation product of an amine and an aldehyde or similar carbonyl-compound, e.g., the resinous condensation product of m-phenylene diamine and formaldehyde described in U.S.A. Specification 2,106,486. The treatment also removes amino acids and reduces the colour. The exhausted condensation product may be regenerated by treatment with sodium hydrate or carbonate. The treatment may be used in a process in which the mother liquors from the first crystallisation are again submitted to conversion by heating with acid, acid being removed after the first and second conversions. Hydrochloric or sulphuric acid may be used as the converting acid. The crystallisation is effected during movement as described in Specifications 227,140 and 232,160, [both in Class 127].

Filed: 1951-02-05
Abstract: 675,649. Electrostatic generators. SOC. ANON. DE MACHINES ELECTROSTATIQUES S.A.M.E.S., and CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Feb. 5, 1951 [Feb. 7, 1950], No. 2784/51. Class 35. Periodic reversals are induced in the output polarity of an electrostatic generator by connecting a condenser of large capacity between the charging brushes of the exciter and generator. The charging brushes are those which are connected to the rotor plates for the purpose of carrying charge to them when they are facing a charge inducing stator plate. The rotary plates of the exciter and main machine are mounted on a common insulating core 5 which rotates within a pair of half-cylindrical stationary plates 1, 2. The main generator plates 7, 8 are engaged during rotation by a charging brush 12 and output brush 11, the stator plate 1 acting as output screen and plate 2 acting as charge inducer. The exciter rotor plates 13, 14 are similarly engaged during rotation by charging and output brushes 17, 18, respectively, while in this case the stator plates 1, 2 act as charge inducer and screen, respectively. The casing 19 is filled with compressed gas. The output brush 11 of the main generator is connected to the stator plate and output terminal 20a, and the output brush 18 of the exciter is connected to the stator plate 2. The charging brush 12 of the main generator is connected through the condenser 24 to the frame 19 of the machine and to the charging brush 17 of the exciter. The capacity of the condenser 24 is greater than the maximum capacity that can exist between the plates of the machine and it may be shunted by a voltage limiter. In operation, charge passes alternately from the machine to the condenser and vice versa so that the output potential varies in sign with a frequency depending on the size of the condenser and the amount of its leakage, a resistance or discharge device being shunted across the condenser to modify the frequency, if desired. A device is described, in which the polarity may be fixed at will, comprising a discharge circuit in series with the condenser which is shunted by a normally closed switch to render the condenser inoperative and so fix the polarity. Alternatively, the condenser may be shunted by a diode to fix the polarity automatically by conducting current, and so rendering the condenser inoperative, in one direction only.

Abstract: 715,910. Generating combustion products under pressure. ROLLS-ROYCE, Ltd. Jan. 21, 1953 [Feb. 1, 1952], No. 2794/52. Class 51 (1) In an annular air jacketed type of combustion chamber of a gas turbine engine, an annular wall section of a flame tube is formed of a number of segmental parts having flanges along their adjacent edges, the parts being secured together by means of channel members which straddle the flanges, and retainer members in contact with the surfaces of the segmental parts opposite those from which the flanges project, the channel and retainer members being in interlocking engagement. In the embodiment shown, both the inner and outer walls of the annular flame tube are formed in accordance with the invention, the walls being formed of annular sections 18 ... 24 each of which is formed of four segmental parts. The parts have axially-extending flanges such as 19a along adjacent edges and the sections are corrugated where they overlap to form air inlets to the combustion space. A channel member 31 stradd'es flanges of the four flame tube sections and is stepped to allow for the increasing diameters. The retainer member comprises a T-section member 32 having a common flange 32a and stepped web portions 32b, the webs of the T-member being in contact with the inner surfaces of the segments, and the flanges projecting radially outwardly between the flanges of the segmental parts. The flange of the T-member is formed with lugs 34, slotted at 35 and the base of the channel member is formed with slots 33, the undercut lugs being passed through the slots to engage with the base of the channel upon axial movement. The channel and T-members abut against the flame tube structure at one end and are prevented from disengagement bv suitable means at the other end. The inner wall of the flame tube is similarly formed. The flanges of the channels associated with the inner wall of the flame tube are notched to engage a circumferential flange formed on the ring 25b forming part of the inner air casing wall 25. The ring 39 is axially s'idable and engages parts welded to the segments of the flame tube wall 24 and also engages the T-section retainer members. The ring 39 is locked in position by means of pegs 41 mounted in tubular members 42 which extend across the flame tube and are bolted to the outer air casing. The tubular members are surrounded by U-section jackets 46 to which cooling air is supplied, the air discharging therefrom across the nozzle boxes 16. Specification 715,909 is referred to.

Abstract: 1377502 Control of D.C. motors CABLEFORM Ltd 12 Jan 1972 [20 Jan 1971] 2812/71 Heading H2J A control system for the motor of a battery operated vehicle comprises a D.C. switch S for controlling the supply of current from the battery B to the electric motor A, F, a by-pass contactor CT2 having contacts ct2 which, when closed, shunt switch S, a microswitch MS2 operable by a speed controller in its maximum speed demand (40) condition and included in an enabling circuit of the by-pass contactor CT2 and time delay means for delaying the energization of contactor CT2 as a function of the motor current. Voltage developed across a resistor R10 controls the current through a transistor T5 included in the charging circuit of a capacitor C1. Capacitor C1 remains clamped by a transistor T 1 until predetermined control contacts MS 1, rlb1, rlc1, are closed and the speed controller is in its maximum demand position (switch F/R S being operated appropriately to select forward or reverse). The bistable switching circuit T2, T3, D1, R2, changes state when the voltage of capacitor C1 reaches a predetermined level and thereby causes energization of a relay RLA having contacts rla1 included in the energization circuit of the by-pass contactor CT2. Voltage VI from resistor R10 is compared with reference voltage VR and amplifier AMP with feed-back H provides an output signal combined in a unit E with the demand signal VD from the speed control pedal to provide a modified control signal to switch S. The amplifier output signal is also connected to one end of a potentiometer supplying the base of a transistor T5 with collector load R1 and C1, such that the signal controls the charging of C1 in a time inversely proportional to the motor current. A transistor T4 switches off switch S prior to operation of by-pass contactor CT2 and ensures that it remains off until CT2 is opened.
