Title: Improvement in gas-lubricated bearing
IPC: F16N15/00
Filed: 1946-07-10
Abstract: 614,279. Grinding and polishing. THURSTON, A. P. (Ford Instrument Co., Inc.). July 10, 1946, No. 20612. [Class 60] [Also in Groups XXVI and XXXIV] An air or gas-lubricated bearing for highspeed rotary spindles for grinding wheels comprises a split block with its two parts yieldably and radially separable under the pressure developed by the high speed which alone increases the pressure of the gas sufficiently to support the spindle. The spindle may carry a gas turbine and an end-thrust bearing comprising a disc between two spring-mounted plates which are axially movable to vary the spacing between the disc and the plates. In a modification, the turbine exhaust engages two lateral plates, the spacing of one being variable to produce a pressure differential to cause axial movement of the turbine, this axial movement being reversed at its limits. The shaft 10, Figs. 3, 4, carries a grinding wheel 11 and rotates within blocks 17, 18 held together by leaf-springs 21 engaging .grooves in studs 20 carried by block 18 and extending through block 17. To eliminate any necessity to provide yieldable support for the bearing surfaces 15, 16 transverse to the studs 20, the bearing surfaces are channelled at 28. The shaft 10 is rotated by an air turbine comprising a vaned rotor 30 in a housing 31 having admission ports 34, the air being discharged through openings 39 around the rim 38 of a sleeve 37 carried by the shaft and the centre part 14 of the shaft. The exhaust pressure is equalized by baffle plates 40. Secured to an extension 35 of the shaft is an end thrust bearing disc 45 running between stationary plates 47, held on opposite sides of a ring 48 by spring clips 49. Ring 48 is mounted on trunnions in a yoke 52, Fig. 5, which swivels on a pin 54 in a block 56, where it is retained by a ball 57 and spring ring 58. Block 56 is secured to an arm 60 sliding in the lower bearing block 18 and held by a spring 68, Fig. 9, against an adjusting screw 65. In a modification, Fig. 9, the disc 45 engages fingers 75, 76 on one arm of a bellcrank 77 pivoted on a bracket 78 carried by the slide 60. The other arm 85 of the bell-crank engages a cam plate 86 attached to a plate 82 hanging loosely from a pin 84, this plate 82 replacing the outer plate 40 of Fig. 4. The axial oscillation of shaft 10 is useful in polishing or grinding operations to avoid marks on the finished article due to the grinding wheel itself.

Title: Improvements relating to the counting of electrical impulses
IPC: H03K23/74
Filed: 1943-12-10
Abstract: 567,633. Electric signalling systems. SIEMENS BROS. & CO., Ltd., and LONG, D. P. Dec. 10, 1943, No. 20733. Addition to 471,987. [Class 40 (i)] [Also in Group XXXIX] In a relay counting chain in which the operation of each counting relay shortcircuits the impulse repeating relay and thus terminates the impulse, as described in the parent Specification, the impulse repeating relay is held locally in the charging circuit of a condenser while an impulse is being transmitted in order to guard against its release during the operating period of a counting relay. The non-inductive resistances shunting the counting relays which were previously provided for the same purpose are dispensed with. In Fig. 1, the repeating relay X is normally energized over resistances LR, HR, and is switched into the impulsing circuit when the impulsing contacts p change over, a charging circuit for condenser or in series with the relay being completed at the same time. When the counting relay A, for example, energizes, it short-circuits relay X at contact a<1> before transferring the impulse circuit at contacts a<2> to the next relay of the chain. In a modification, Fig. 3, relay X is provided with a second winding of high resistance in series with condenser Q. In Fig. 2, relay X is energized by the operation of contacts p and the impulse circuit is completed when they restore the. charging-circuit for condenser Q through relay X being made as before. Specification 462,773, [Group XXXIX], is referred to.

Filed: 1935-07-22
Abstract: 460,206. Heat - storing apparatus. PETERSILIE, F. July 22, 1935, Nos. 20786 and 20787. Convention dates, July 21, 1934 and March 27, 1935. [Class 64 (ii)] In water-heating apparatus comprising a heat storage block A which heats the water in a water-containing member B, the member B is movable relatively to the block A in order to vary the rate of transmission of heat to the water. The movement is effected by mounting the member B on nuts on a screw U which may be rotated by an electric motor D. Two thermostats are provided in the water outflow pipe from member B. If the temperature rises above a desired maximum one thermostat starts the motor D in the direction which lowers the member B from around the block A. If the temperature falls below a desired minimum the other thermostat operates the motor to raise the member B around the block. The member B may be a tube coil or an annular chamber with radial partitions. Flexible water connections P1 and P2 are provided to allow for the motion of member B. In an alternative construction, the heat storage block 1, Fig. 7, is mounted on a platform swivelling on a pivot 22. The block can then be rotated into or out of proximity to the water-containing member 28 as desired. A heat insulating wall 6 is also fixed on the platform to shield the member 28 from heat radiation when the block 1 is swivelled into the other half of the containing chamber 9. In both constructions the containing chamber for the apparatus is heavily insulated. The heat storage block is provided with electric resistance heating elements. The thermostatic control of the motor D is put into operation by switch means either directly connected to the outlet cock of the apparatus or operated by pressure responsive means situated in the outlet pipe.

Patent GB-716326-A (GB)
Title: Process for the production of aliphatic alcohols
IPC: C07C29/141
Filed: 1951-09-04
Abstract: Aliphatic alcohols are produced by hydrogenating the products of an Oxo synthesis from CO, H2, and olefins obtained by reacting CO and H2 in the presence of a fixed iron catalyst at 160-280 DEG  C., 10-100 kg./cm.2, and a charge rate of at least 500, preferably at least 1000 vols. of gas/vol. catalyst/hour.  With such high charge rates using reactors of 10-12 m. in length, a highly olefinic product is obtained with a high proportion boiling above 320 DEG  C.  The subsequent Oxo synthesis gives good yields of C6-C7 alcohols.  The olefinic product may be fractionated and desired fractions only converted to alcohols, e.g. the 320-460 DEG  C. fraction to C18-C22 alcohols.  Other fractions may be subjected to cracking, aromatization, isomerization or polymerization.  The remaining paraffins may be mildly hydrogenated.  In an example, the catalyst contains iron, 30 per cent as metal, copper, and potassium silicate on kieselguhr, and a CO, H2 mixture is charged at 750 vols./vol./hour together with 3 times its volume of recycle gas.  A product fraction boiling up to 320 DEG  C. (C3-C18) is subjected to an Oxo synthesis using cobalt as catalyst, and hydrogenated with the same catalyst.  A fraction boiling at 320-400 DEG  C. may be included in the feed to the Oxo synthesis when additional alcohols, including C18-C25, and higher paraffins are obtained.
