Abstract: 488,003. Casting composite bearings. SPRINGORUM, K. Nov. 16, 1937, No. 31465. Convention date, Jan. 28. [Class 83 (i)] Casting processes.-In lin. ing a steel bearing-shell 1, especially if the lining metal 2 is lead bronze, it is first filled with molten bearing metal and then the excess is expelled upwardly by inserting a mandrel 3. In the case of a bearing-shell coated in. side and outside the metal is poured into the middle of the shell 1, Fig. 2, and passes by channels to the outside where it rises between the shell and the chill mould 6. To reduce the risk of liquation, chills 5 covered with 1 mm. of sand are used at thick collars 4, the mandrel is rounded at 11, 12, and the cross section of the cast metal 2, after the excess has been expelled, is substantially constant throughout its length. In Fig. 2, the inner lining tapers upwardly and the outer downwardly so that the sum is constant.

Title: Improvements in or relating to process of producing furfuryl alcohol and catalyst thereof
Inventor: SWADESH SAMUEL
IPC: C07D307/44
Filed: 1953-11-16
Abstract: Furfuryl alcohol is produced by reducing furfural completely in vapour phase while in admixture with a stoichiometric excess of hydrogen by passing the mixture at a temperature of 120 DEG  to 155 DEG  C. over a catalyst prepared by mixing 6 parts by weight of copper oxide with from one to four parts by weight of a sodium silicate solution of the type in which the ratio of Na2O to SiO2 is as 1:3.22, and reducing the copper oxide to copper with a gaseous stream containing hydrogen at a temperature of 150 DEG  to 400 DEG C. (see Group III).  The excess hydrogen from the furfural reduction may be mixed with fresh furfural and recycled to the converter.  A detailed example is given in which furfural is reduced at temperatures varying from 110 DEG -117 DEG  C., using catalysts containing, respectively, 5, 10 and 20 per cent of sodium silicate based on the copper oxide before reduction.  A comparative run using a copper catalyst alone is also described. Specification 734,118 is referred to.ALSO:A catalyst, particularly adapted for the reduction of furfural to furfuryl alcohol, is prepared by mixing six parts by weight of copper oxide with from one to four parts by weight of a sodium silicate solution containing about 37.6 per cent of actual sodium silicate of the type in which the ratio of Na2O to SiO2 is as 1:3-22, forming the resultant mixture into pellets and reducing the copper oxide therein to metallic copper with a gaseous stream containing hydrogen at a temperature of 150 DEG  to 400 DEG C.  Thus, the temperature may be 150 DEG C. when the gaseous stream is 100 per cent hydrogen and is preferably 300 DEG -400 DEG C. when a gaseous stream of 5 per cent hydrogen and 95 per cent nitrogen is used.  A detailed example describes the preparation of catalysts containing 5, 10, 15 and 20 per cent of sodium silicate. Specification 734,118 is referred to.

Title: Apparatus for folding sheets
IPC: D06F89/00
Filed: 1946-10-28
Abstract: 618,157. Folding fabrics. ARMITAGE, A. E., and GRAHAM, W. Oct. 28,1946, No. 31942. [Class 42(ii)] An apparatus for folding sheets comprises a plurality of spaced travelling bands for conveying a sheet, light-responsive control means arranged to receive light through a space between the bands, and to be screened from light by the passing sheet, and a device controlled by the light-responsive means for engaging and raising the leading edge of the sheet to permit the remainder thereof to be conveyed therebeneath to form a fold, and for releasing the leading edge when the fold has been made. A pair of uprights 2 are carried by the frame on which the rollers for supporting and driving the conveyor bands 1 are mounted; these carry brackets 5 connected by a cross-bar 6, and ball bearings 7 in which a cross-shaft 10 is joura number of fingers 12 having at their ends rollers 13 which, in the operative, raised position, contact the cross-bar 6, and in the inoperative position extend downwardly nalled, the latter having clamped thereon between the tapes 1. The cross-shaft 10 has fixed to it a cross-lever (not shown), one end of which may be operated upon by a solenoid, while the other is counterweighted or spring-loaded. The cell 19 of a photo-electric relay is positioned beneath the conveyor tapes 1, and lamps 17, 18 are secured to a rod 16, forwardly and rearwardly of the cross-bar 6, and are directed at the cell 19. Interruption of the lightbeams by the leading edge of the sheet causes the solenoid to be de-energized and the counterweight or spring causes the fingers 12 to engage and raise the leading edge, which is then held between the rollers 13 and the cross-bar 6. The remainder of the sheet is carried forward, forming a fold, until the passage of the rear edge allows light from the lamp 18 to reach the cell 19, when the solenoid is energized to cause the fingers 12 to drop, the front edge being thus released and falling on the rear edge. A dashpot may be connected to quickly at first, and slowly thereafter. the solenoid to allow the fingers to open Instead of operating the fingers electrically, the photo-electric cell may act through a relay controlling pneumatic or hydraulic power. A further fold may be formed by a second, similar device. Specification 587,593 is referred to.

Title: Improvements in textile yarn or filament winding apparatus
Inventor: WHITELEY JOHN
IPC: B65H67/056
Filed: 1966-07-18
Abstract: 1,139,695. Continuous winding. T.M.M. (RESEARCH) Ltd. 16 Oct., 1967 [18 July, 1966], No. 32178/66. Heading D1J. A yarn winding apparatus for winding two coaxial packages has a yarn guide 5 releasably secured to a reciprocating traversing member 16. The guide 5 is initially securable in a first position (as shown at 18) to the traverse 16 to form a first package 11 but is displaceable, e.g. by a means 23, to a second position 20 to transfer the winding process to the other package support 12. As shown, the reciprocating traverse 16 is formed with three waisted portions 18, 19 and 20 and the yarn: guide 5 is fitted with a spring-loaded catch 21 to engage with these waisted portions. The guide is displaced between the winding stations by means 23, which comprises two pairs of spring loaded pawls 24 and 25, and 26 and 27 by pivoting the displacing means about a horizontal axis so as to position one of the pawl pairs in the path of guide pin 22. The pawl 26 thus abut the guide pin 22 and cause the guide 5 to be displaced relative to the traverse 16 as the latter reciprocates and then engage with waist 19. The next reciprocation of traverse 16 causes guide 5 to move past pawl 27 and the next reciprocation causes pawl 27 to abut guide pin 22 and displace it to engage with waist 20. Winding then commences on package support 12. The guide can be returned to wind package support 7 by similar use of pawls 24 and 25. Alternatively a forked arm (not shown), which pivots about an axis at right angles to the traverse direction, can engage pin 22 to displace yarn guide 5 between the winding stations. A stationary yarn guide 28 may pick up the yarn during transfer of winding from one package support to the other and sever the yarn, see Figs. 4 and not shown. The cut end of the yarn can be gripped at the start of winding by a toothed annulus 29 on the package support. The package supports 7 and 12 or the packages are rotated by roller 6. The fully wound package can be lifted off the roller 6 to be doffed.

[Also in Division H1] A combined electrical connector and filter assembly comprises a grounded plate 2 having a plurality of openings, and insulating blocks 4 and 5 positioned on opposite sides of the plate, each block having a plurality of sockets aligned with the plate openings, and each opposing pair of sockets having extending through them a pin 10 carrying ferrite beads within a tubular ceramic capacitor. The capacitor 13, Fig. 2, has inner electrodes 14 and 15 and an outer electrode 16. Electrode 15 is soldered at 17 to a collar 18 integral with the pin, and electrode 14 is soldered at 19 to a thimble 20 soldered to the pin at 21. The ferrite beads 22 are hermetically sealed within the bore of the capacitor. A split metallic sleeve 23 with axially extending corrugations makes contact between electrode 16 and the grounded plate 2. When the pins are inserted in the sockets, the blocks 4 and 5 are bolted together. In a second embodiment, Fig. 3 (not shown), the filter is contained within a metal tube which is soldered at one end to a collar of insulating material on the pin, and at the other end is sealed by an O-ring. In a further embodiment, Fig. 4 (not shown), the pin has spaced metallized ceramic collars soldered to it to take the insertion and removal thrusts.
