Title: Improvements in fluid supports
IPC: F16C32/06
Filed: 1946-07-25
Abstract: 642,891. Bearings. GERARD, P. L. J. July 25, 1946, Nos. 22193, 22194 and 22195. Convention dates, Jan. 19, 1945, Oct. 4, 1945, and Oct. 17, 1945. [Class 12 (i)] A fluid support bearing supporting or guiding a movable member comprises at least two recessed portions in the bearing surface supplied with fluid under pressure and longitudinal grooves between said recessed portions to discharge the pressure fluid therefrom. (The movable member is automatically centralised in the bearing by the variation of the throttling effect on the fluid flowing to the discharge grooves through the narrow clearance spaces between the bearing surfaces.) As shown, a shaft bushing 2 in a fixed housing 3 has a succession of grooves b<SP>1</SP>-b<SP>7</SP> interspacing a succession of chambers a<SP>1</SP> - a<SP>7</SP> and extending longitudinally on its inner surface. Annular grooves g<SP>1</SP>-g<SP>6</SP> are formed on the outer periphery of the bushing. Groove g<SP>1</SP> conveys pressure fluid from an inlet 6 to chambers a<SP>1</SP>-a<SP>3</SP> via radial passages c<SP>1</SP>. Groove g<SP>6</SP> exhausts pressure fluid from grooves b<SP>4</SP>-b<SP>6</SP> to an outlet 5 via radial passages c<SP>6</SP>, Grooves b<SP>7</SP>, b<SP>1</SP>, b<SP>2</SP>, b<SP>3</SP> respectively communicate with diametrically opposite chambers a<SP>4</SP>-a<SP>7</SP> via passages c<SP>5</SP>, c<SP>4</SP>, c<SP>3</SP>, c<SP>2</SP> and grooves g<SP>5</SP>, g', g3 and g<SP>2</SP>. Thus any tendency of a shaft 1 to contact the bushing 2 in the region of a chamber a<SP>6</SP> due to the pressure in chambers a<SP>1</SP>-a<SP>3</SP>, will increase the pressure in chamber a<SP>6</SP> since the groove b2 which feeds said chamber will have wider communication with chambers a<SP>2</SP>-a<SP>3</SP>. Simultaneously, the evacuation from chamber a<SP>6</SP> will tend to cease owing to the closing of grooves b<SP>4</SP> and b<SP>5</SP>. Similar action applies for chambers a', a<SP>5</SP> and a7. Other constructions are described wherein the chambers and grooves are formed on the outer surface of a fixed inner body such as a pulley axle having longitudinal bores to conduct and evacuate the pressure fluid. In a further con. struction the chambers may be fed direct with pressure fluid through throttling passages, the interposed grooves serving to evacuate the pressure fluid via annular grooves at the extremities of the body in which they are formed. In constructions where two non- rotatable bodies have a relative sliding motion one within the other, the chambers may be formed on the bearing surface of one body and the grooves on the bearing surface of the other body. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specifications 642,940 and 642,941. This subject-matter does not appear in the Specification as accepted.

Title: Pile fabric and method and apparatus for making the same
IPC: D04H11/04
Filed: 1928-08-01
Abstract: 295,323. Oryx Fabrics Corporation, (Assignees of Smith, P. S.). Aug. 9, 1927, [Convention date]. Pile fabrics. - A pile fabric is produced by securing looped pile material 63, Fig. 6, to a fabric backing 72 by means of vulcanized rubber coatings, 65, 73, applied to the fabric and to the loops of pile material. A machine for making the pile loops and for vulcanizing them to the base fabric in a continuous manner is shown in Fig. 7. A batt 10 of pile material preferably goat hair in which the fibres are substantially parallel is fed by a conveyer to a loopforming device 13 comprising presser feet 22, 26, Fig. 3, adapted to press and retain the pile material on blades 16, a loop-retaining blade 24 adapted to engage the pile material between two blades 16, and a loop-forming blade 20 adapted to force the pile material between two of the blades 16. The pile-forming members are capable of sliding against one another and are controlled by springs so that the reciprocation of the blade 20 causes the members 22, 24, 26, 20 successively to engage the pile material. The blades 16 may be arranged as shown in Fig. 3 or around a rotating drum 11 as shown in Fig. 7. The pile material forced between the blades 16 passes beneath a roller 64 to receive a vulcanizable rubber coating 65 from a tank 66. The coating is partly dried by hot air supplied from a pipe 70, the interior of the drum being heated by hot air from a pipe 68. A base fabric 72 receives a rubber coating 73 from a tank 76 and passes over a roller to the drum 11 where it is caused to adhere to the cemented loops of the pile material. Moulds 80, 82, 83 normally press the base fabric against the pile loops to effect the vulcanization of the coatings by spring-pressed plungers 86, 88 on a heavy member 84 loose on the stationary. shaft of the drum 11. The moulds, the fabric, and the drum, thus move round together until ports 92, 94 are brought into register to allow compressed air to act on the plungers and remove the moulds from engagement with the drum. The moulds then move by gravity in a clockwise direction, the air is exhausted through ports 100, 98, and the springs again cause the moulds to engage the work. The vulcanized fabric may be cooled by an air blast from a pipe 102 and then passes over a roller 104, whereby the pile loops are withdrawn from between the blades 16 of the drum The upstanding pile loops are then cut at 106, brushed or " tigered " at 108, and sheared at 110.

Title: Improvements in the preparation of alloys by sintering
IPC: C22C1/05
Filed: 1946-07-29
Abstract: In a process for the manufacture of hard carbide alloys obtained by sintering, the powder of the hard constituent(s) is coated with a solution of a non-carburized non-oxygenated salt or salts of a binder metal or metals, other than the chlorides of cobalt and iron, and the water is driven off by evaporation from the suspension thus obtained, while the crystals deposited in the pulverulent mass are maintained in homogeneous distribution by agitation, and the mass is subsequently subjected to a chemical reaction by which the salt crystals mixed therein are reduced to the metallic state.  The reduction is preferably effected at a temperature of between 250 DEG C. and 750 DEG C.  The binder metals may be one or more of nickel, cobalt and iron.  Halogen salts of the binder metals may be used.  An example is described of the production of a composition containing tungsten carbides with cobalt and iron as the binder metals.

Title: Machine for automatically sealing paper bottles
IPC: B67B3/04
Filed: 1933-08-12
Abstract: 425,757. Sealing paper bottles; bottle stoppers. RISTOW, C., 6, Flotowstrasse, Berlin. Aug. 12, 1933, No. 22571. [Classes 125 (ii) and 125 (iii)] In a machine for automatically sealing filled paper bottles the bottles are carried in two rows by an endless band through the machine and temporarily brought to rest at four different operating stations at three of which stamps and laterally moving pressure jaws grip and shape the heads of the bottles, press paper discs, (stamped out of a laterally fed paper strip and pre-shaped by a separate stamp) into the bottle necks, and finally flange over the edges of the bottles and fix the discs whereupon fluid paraffin wax is introduced into the space over the disc. As shown an endless chain band 31 carries two rows of holders 32 containing the filled bottles beneath four pairs of stamps 12, 12<1>, 13, 13<1>, 14, 14<1>, 15, 15<1>, being given an intermittent movement from an electric motor 4 via worm wheel 7, shafts 8, 21, 24, a crank arm 25 on 24, and a Maltese cross 28. At position I bottles are placed in the holders. At position II the stamps 12, 12<1>, reciprocated (as are the other stamps) from the shaft 8, enter and shape the heads of the bottles which are held (as they are also in positions III and IV) by pressure jaws 40 ... 43, Fig. 2, driven from shafts 8, 21. At position III paper strip-fed from a roll 56 is impressed by mechanism including a feed roller 62 with the shape of the discs, and passes beneath a reversal-preventing pawl 73 ; stamps 60, 60<1> then provisionally shape the discs, giving them a convex curvature, and finally the stamps 13, 13<1>, stamp out the discs and force them into the bottles. These stamps may be provided with a series of prongs which cooperate with grooves in the pressure jaws 40 &c., to punch holes in the bottle edge to facilitate removal of the disc, as suggested in Specification 390,703. As shown, the stamps 60<1>, 60, 13<1>, 13 are spaced at regular intervals. In order to save paper the strip is fed at each operation of the stamps only two-thirds of the distance between two adjacent stamps, so that from the length of strip extending from stamp 60<1> to stamp 13 ten discs are eventually stamped out and pressed into bottles. At position IV the stamps 14, 14<1>, force the discs down the bottle necks to the shoulder S and flange over the edges of the neck. At position V paraffin wax from a reservoir 84 is fed on to the discs via cocks 86 which are closed by springs 88 connected to arms 87 on the cocks and opened by the movement of sleeves 89 relative to the stamps 15, 15<1> when the sleeves descend and rest on the bottles. A hand wheel 37 is provided for adjusting the conveyer band before starting the machine.

Title: Computer controlled rf noise and modulation analyzer
IPC: G01R29/06
Filed: 1972-05-15
Abstract: 1382893 Computer controlled test and spectrum analysis system WESTINGHOUSE ELECTRIC CORP 15 May 1972 [22 June 1971] 22638/72 Heading G1U A computer controlled system is described for analyzing, in various ways, the r.f. output signal from a unit 16 under test. The full sequence of tests that can be performed is as follows, but the system is stated to be programmable to perform sub-sequences or to repeat the whole sequence having varied a parameter of the device under test. 1. Locking of system to unit under test The output signal from the unit under test is passed via an attenuator 40 and mixed 36 with a frequency swept signal from a local oscillator 20. The resulitng IF signal is pre-amplified 48, limited 56 (at 30 Mc/s) and applied to a quadrature detector 64 forming part of a phase-lock loop including an amplifier 68 and a voltage controlled 30 Mc/s crystal oscillator 66. As the local oscillator 20 is swept, under the control of a device 32, the phase-lock loop attempts to lock the limited IF output. When this is achieved, the local oscillator is clamped at the frequency it then has, and the IF is then precisely 30 Mc/s. 2. Measurement of r.f. power The local oscillator 20 having been adjusted to give an IF of 30 Mc/s, the IF signal is passed via couplers 50, 52 to an RF detector and its output is indicated on a digital voltmeter DVM. This indication thus indicates r.f. power. The computer then adjusts the attenuator 40, in 2db steps, until the DVM indicates a predetermined reference level. Thus, the IF signal is brought to a reference level and the attenuation necessary to do this is also a measure of r.f. power. 3. Measurement of FM noise The output from the quadrature detector 64, which will only contain the noise frequencies, is passed via a filter 74, amplifier 84 and a switch 86 to a digital wave analyzer 22, which is progressively stepped over the frequency range of interest by the computer, to provide, via the DVM, noise level measurements vs frequency, (the frequencies all being relative to the IF frequency of 30 Mc/s). The output of the digital wave analyzer is also monitored by a threshold detector 118 which may provide an overall "no-go" indication if the noise intensity is too high. 4. Measurement of AM noise AM noise is measured in a similar way to FM noise by applying the output of an AM detector 96 to the wave analyzer. 5. Linearity of output unit under test When the unit under test produces a swept frequency signal, the linearity of the sweep can be evaluated by the computer by counting the zero cross-overs, detected by a device 76, of the first order sideband from the quadrature detector. Modulation index The FM index of modulation of a signal from the unit under test can also be evaluated by the computer from a measurement, by the DVM, of the output of the amplifier 84.
