Title: Fluid flow machine
Inventor: PETRIE JAMES ALEXANDER
IPC: F01D3/00
Filed: 1961-04-05
Abstract: 931,904. Bearings. ROLLS-ROYCE Ltd. March 30, 1962 [April 5, 1961], No. 12253/61. Class 12 (1). [Also in Group XXVI] A fluid-flow machine such as a gas-turbine engine, comprises rotatable shafting, one or more bladed members being mounted on the shafting, the members being subject, in operation, to thrust from the working fluid flowing through the machine. A thrust bearing is provided for the shafting, the thrust bearing being arranged to be subjected to the thrust or net thrust from the bladed member or members, there being also provided resilient means for urging the thrust bearing in a direction to oppose the thrust or net thrust, also means for applying to the thrust bearing one or more fluid pressures whose effect or net effect is also to oppose the thrust or net thrust. The invention is described with reference to a gas-turbine engine which comprises an auxiliary compressor 18 which may supply air under pressure for operation of blown flaps on an aircraft in which the engine is installed. The engine comprises a main compressor 15 and a turbine 16 mounted on a shaft 12 which is supported in bearings 13, 14. The engine also comprises a separate power turbine 26 the shaft 22 of which is mounted in bearings 23, 24, the shaft 22 being in splined connection with a shaft 17 to which the rotor 18 of the auxiliary compressor is secured. The shaft 17 is supported in bearings 19, 21. The intakes 28, 29 of the two compressors are disposed adjacently, the air streams being guided from the annular opening 27 by a baffle 31. The bearing 23 is arranged in accordance with the invention and as shown in Fig. 2, comprises an outer race 23<SP>1</SP> which is supported within a resilient diaphragm 33. The outer periphery of the diaphragm is secured between a ring member 34 and an annular flange 35 of a radially flexible ring 36, the ring 36 being secured to the radially inner ends of stator blades 37. Annular casings 40, 41 are secured at either side of the diaphragm so as to afford chambers 43, 44 at the upstream and downstream sides respectively of the diaphragm, the diaphragm 33, ring 34, flange 35 and casings 40, 41 being secured together by bolts 42, Fig. 3. Holes 45 are formed at the periphery of the diaphragm 33 between the bolt-receiving holes and holes 46, 47 and 48 are formed in the casing 40, flange 35 and ring 34 respectively (see Fig. 4), so that pressure fluid at the upstream side of the diaphragm assembly may pass to the chamber 44 at the downstream side of the diaphragm. Similarly, holes 50, 51 and 52 are formed in the casing 41, ring 34 and flange 35 respectively (see Fig. 5), whereby pressure fluid. at the downstream side of the diaphragm assembly may pass to the chamber 43 at the upstream side of the diaphragm. Since the fluid pressure at the upstream side of the diaphragm assembly is greater than that at the downstream side, the resulting pressure difference on the diaphragm itself will act in the upstream direction and so tond to balance the downstream thrust on the turbine rotor 26.

Title: Improvements in or relating to oil filters
IPC: B01D29/00
Filed: 1935-04-25
Abstract: 455,638. Filters. SCINTILLA SOC. ANON., Soleure, Switzerland.-(Assignees of Schaeren, E. ; 38, Florastrasse, Solothurn, Switzerland) April 25, 1935, No. 12435. Convention date, May 13, 1934. [Class 46] The casing a of an oil filter is divided into a lower unfiltered liquid compartment and an upper compartment for filtrate by a downwardly extending partition i which supports a filtering element. Nipples b, c, for inlet and outlet connections are arranged at the level where the partition i meets the casing. The nipples are similar initially but an aperture p is bored through the lower part of that selected for connection to the inlet d and an aperture q in the upper part of that to be connected to the outlet e. Alternatively each nipple may have initially two apertures one of which is sealed before the connections are made. The oil is filtered as it passes outward through a gauze cylinder s<1> and a cloth cylinder s<2>, these cylinders being supported between rings s spaced apart by distance bolts t. The lower ring s makes joint with a central aperture in the partition i and the upper ring is closed by a cover u. The filter element is held in place by a spring v engaging the cover u and the cover c<1> of the casing and surrounding a nut a<1> which is threaded on to a central bolt wand holds the cover c<1> in place. A nut x on the lower end of the bolt w holds a washer z in place to seal the lower end of draining passages y. Grooves r<1>, g<1> on the bolt w and the nut a<1> respectively serve as air vents from the interior of the filter element and from the casing under control of a head f<1> having a threaded shank engaging within the nut a<1>. When the pressure within the filter element rises sufficiently to overpower the spring v the filter element rises and oil passes without being filtered from the lower to the upper compartment.

Patent GB-109614-A (GB)
Title: Improvements in or relating to Automatic Couplings for Vehicles.
IPC: B61G1/28
Filed: 1917-08-31
Abstract: 109,614. Akt.-Ges. der Eisen & Stahlwerke, vorm. G. Fischer. Sept. 15, 1916, [Convention date]. Couplings, automatic. - An automatic coupling for railway and like vehicles comprises a coupling lock arranged at the level of the traction line and a centring device below the coupling lock consisting of a funnelshaped guide 10, Figs. 3 and 4, having a horn 11 projecting outwardly from one lateral wall of the funnel to a point on the extended axis of the funnel and adapted to co-operate with the funnel of the opposed coupler-head. In the construction shown in Figs. 3 and 4, the coupling lock comprises a projecting coupling eye 2 adapted to enter a recess 4 in the opposite coupler-head and to be locked therein by a vertically sliding bolt 5 operated by a bent lever 8<11> secured to an horizontal spindle 7. Mounted on the spindle 7 is an arm 12 to which a weighted pawl 13 having a shoulder 14 is pivoted. Assuming that the coupling is initially in its locked position, its operation is as follows. The bolt 5 is withdrawn by rotating the lever 8<11> until it reaches the position marked I in Fig. 3; at the same time the weighted pawl 13 is raised and the shoulder 14 is brought to rest on the nose of the projecting horn 11 of the opposite coupler-head. As the vehicles separate, the horn 11 is withdrawn and the pawl 13 falls a short distance until the shoulder 14 rests on a ledge 15 of the coupling-head, and the spindle 7 and lever 8<11> are rotated to the set-for-coupling position marked II. When the coupler-heads are next brought together, the horn 11 pushes the shoulder 14 off the ledge 15, and the pawl 13 falls under gravity so as to rotate the spindle 7 and lift the bolt 5 into its locking position, the lever 8<11> then being at the position III. In a modification, Fig. 12, the locking is effected by an horizontally sliding bolt 20 which is normally held in a locking position by a spring 26 acting through the medium of a bent lever 24<1> and a vertical disengaging spindle 22. The weighted pawl is replaced by an horizontally moving pawl 30 having a shoulder 32. When the bolt 20 is withdrawn for uncoupling, the pawl slides until the shoulder 32 falls into abutment with an offset portion 33 of the opposite coupling eye 17<1>; as the vehicles separate and the eye 17' is withdrawn, the spindle 22 is rotated and the shoulder 33 comes into abutment with a support 34 on the coupler-head, this being the set-forcoupling position. In effecting the coupling, the pawl 30 is lifted out of engagement with the support 34, thus allowing the spring 26 to rotate the spindle 22 and shoot the bolt 20. The disengaging lever 8<11> or 24<1> may be operated by any known form of operating mechanism, or by means of airpressure admitted to a cylinder having a piston in connexion with the lever, or electrically by means of the core of a solenoid in connexion with the lever.

Title: Crystallizer apparatus
IPC: C13B30/02
Filed: 1944-07-03
Abstract: Crystallizing apparatus comprises a tank which contains a rotary drum supporting members into and out of which heat-exchange medium is passed, these members being arranged in independent groups such that the medium supplied to and discharged from one group does not enter another group.  Rotary drum 22, mounted in stationary tank 16, supports hollow members 25 which are thin so as not to cause rotation of the material being crystallized.  Scrapers 31 are mounted on at least one of the members at each end of the drum so as to scrape the end walls of tank 16.  Heat exchange medium is supplied to the apparatus through conduit 27, Fig. 1, and delivered to the members 25, through apertures 32, Fig. 4, by four pipes 26 which have discharge openings 33.  The supply of medium to the pipes 26 is controlled by valve 28, Figs. 4 and 6, which rotates conjointly with drum 22 and is designed so that any given pipe and its associated group of members only receives medium, from stationary conduit 36, during one quarter of a revolution.  Spent <PICT:0598052/III/1> medium drains out of the members through apertures 32 into drum 22 and then discharges over weir 29 into receptacle 30.  Temperature regulation can be effected by controlling temperature and volume of medium admitted to valve 28.  In a second embodiment, valve 28 is eliminated and medium is supplied to a single rotary conduit which extends axially through the drum supporting a depending baffle which separates fresh from spent medium.  In a third <PICT:0598052/III/2> <PICT:0598052/III/3> <PICT:0598052/III/4> embodiment in which heating in one group and cooling in another may be effected simultaneously, the drum contains six pipes and the medium, instead of being supplied to and discharged from each member intermittently, flows through each of the six groups continuously, passing from member to member of any one group by means of conduits located in the forward edges of the members. The crystallization of chemical salts and of hot massecuite from vacuum pans is referred to.

Title: Improvements in or relating to the electrical deposition of organic materials
IPC: C25D13/22
Filed: 1926-05-19
Abstract: 253,091. Kodak, Ltd., (Assignees of Sheppard, S. E., and Eberlin, L. W.). June 8, 1925, [Convention date]. Indiarubber, preparation of.-Rubber is electrolytically deposited from an emulsion or suspension on to an anode of gas-permeable material the rear surface of which is subjected to a reduced pressure so that any oxygen formed in the anode zone is removed through the anode by suction. In the apparatus shown in Fig. 1, the material is deposited into a fabric 7 which is led by rollers 8, 9, 10 over a curved anode 4 of porous carbon forming one wall of a chamber 5 connected to a pump. The degree of suction is regulated in accordance with the current density. In the apparatus shown in Fig. 2 the anode density consists of a hollow cylinder 12 of porous carbon having a collar 13 supported on a bearing 11 and provided with a pulley 14 driven by a belt 15. The anode is provided with a contact ring 19 to which connection is made by a brush 20. The anode is closed at the top by a stopper 16 through which passes a stationary suction pipe 17, the connection being made air-tight by a stuffing-box 18. Cathodes 3 are arranged in a ring round the anode. The deposit may be vulcanized before or after removal. In a modification rubber is deposited on a fabric drawn over a rotating anode. The anode may consist of wire cloth of nickel or a nickel alloy having a mesh of 200 to 300 per inch; the cloth may be rolled to a comparatively smooth sheet. Strands of a non-conductor such as asbestos may be included. The removal of gas may be supplemented by incorporating reducing agents such as sodium or ammonium sulphite or thiosulphate in the emulsion. In an example, a rubber dispersion is prepared by mixing 1000 c.c. of a 5 per cent solution of rubber in benzol with 1000 c.c. of paraffin and 500 c.c. of sulphonated castor oil and stirring the mixture into 3000 c.c. of an aqueous solution containing 150 gms. of Castile soap a semulsifier. Aniline sulphate may be added before emulsification for the purpose of accelerating vulcanization. Vulcanizing agents may be added before emulsification or may be added to the emulsion in colloidal form, or may be omitted, vulcanization in this case being effected by subsequent treatment in a solution of sulphur in sulphur dichloride or otherwise. An ammonium soap is used as emulsifier when a coating of high electrical resistance is desired; the ammonia is driven off during vulcanization. The emulsifying agents may also consist of saturated or unsaturated compounds of fatty acids with alkali metals or ammonium, or of sodium phenol or cresolate with or without excess of cresol or cresylic acid. Direct current either constant or pulsating is employed. The voltage may be 110 and the current  to ¢ amp. per sq. inch of anode surface.
