Title: Improvements in road and rail transport
IPC: B60F1/02
Filed: 1929-01-29
Abstract: 326,935. Moncrieff, A. H. D., and Shearman, J. Jan. 29, 1929. Alternative rail - or - road vehicles. - A vehicle adapted to be used on railwavs or on roads is constructed with principal wheels flanged for rail use and having, on their outside, hubs carrying eccentric sleeves which coact with eccentric openings in the road wheels in such a manner that the road wheels may be made concentric with the rail wheels for use on roads or may be held eccentrically in a raised position when the vehicle is running on rails. Figs. 1 and 2 show a rail wheel in use, with its co-operating road wheel in the raised inoperative position. The rail wheel 2 is bolted to a sleeve 6 which rotates, through the medium of opposed taper roller bearings 5, on the end 4 of a tubular axle which supports the weight of the vehicle. The driving axle 3 is connected by splines 4<1> to a driving element 10 bolted to the sleeve 6. Mounted on the outside of the sleeve 6 is an eccentric 7 which bears in an eccentric opening in the road wheel 8. When the two eccentrics are in opposition, the road wheel 13 and the rail wheel 2 are concentric and as the road wheel is of larger diameter the rail wheel is raised clear of the road. The two eccentric members are then coupled rigidly to the rail wheel and to the driving element 10 by long bolts 11, 12 inserted into holes 17, 18 in the driving element. When the road wheel is out of action the two eccentric members are held in their raised position by means of the bolts 11, 12 which then enter screwed holes in a bracket 22 depending from the vehicle frame.

Title: Improvements in cross-bar switches
Inventor: STEFFENS OSZKER
IPC: H01H67/26
Filed: 1960-01-28
Abstract: 938,272. Cross-bar switches. BUDAVOX BUDAPESTI HIRADASTECHNIKAI VALLALAT. Jan. 28, 1960, No. 3128/60. Class 40 (4). Each set of contacts in a crossbar switch comprises spring blades 3 the operating plate 31 of which is selectible by spring fingers 7 of a select bar 6 and is operable one way to engage a fixed contact multiple 36 or is operable the other way to engage a second fixed contact multiple 37. The spring blades are as shown in Fig. 7 with lacerations 39 bent outwards one way and lacerations 40 bent outwards the other way. By forcing the lacerated ends of the spring blades into narrow slots 42 in the operating plate 31 the lacerations are pulled in and are pre-stressed. When the plate 31 is pushed to the right, as shown in Fig. 4, by operate bar 5a, or to the left by operate bar 5b the contacts 41 on the lacerations only deflect on contact with multiples 36 or 37 after the prestress is overcome. As seen in Fig. 3 the spring fingers 7 select one or other of adjacent spring blade sets in a row served by selector bars 6 and the magnet pairs 91, 92 &c. A selected spring blade set is operated one way or the other if the operate bar 5a or 5b is actuated by magnet 81a or 81b, respectively. In constructing a complete cross-bar switch each pair of magnets 81a, 81b, the operate bars 5a, 5b, and the associated contacts, comprise a detachable unit termed a twin-bridge. To hold the spring blades 34 centrally of the alternate multiples 36, 37, the operating plate is engaged by strong spring arms 64, 65 in slots the ends of which coincide with mounting plates 67, 68 against which the spring arms bear. The operating plates may be deflected against the spring arm at one end to the extent of the slot engaged by the spring arm at the other end. The spring arms 64, 65 may lie outside the mounting plates 67, 68, or engage opposite sides of one of these plates (see Figs. 12 and 13, not shown). As shown in Fig. 8, the spring blades 34 are not pre-stressed but engage slots in the operating plate 31 with sprung mutilations 44a.

Patent GB-285405-A (GB)
Title: Improvements in apparatus for folding sheets of paper and the like
IPC: B65H45/14
Filed: 1928-02-02
Abstract: 285,405. Spiess, G. Feb. 15, 1927, [Convention date]. Folding paper.-In machines for folding paper by feeding it against a stop which buckles it between folding-rollers 5, 6, the sheet is gripped between the folding position and the stop 7', Fig. 4, so that it is buckled between the feeding- rollers 5, 17, Fig. 1, or 5, 26, Fig. 4, and the gripped portion of the sheet. Inclined-roller feedtables 2, 3, are arranged on opposite sides of the folding position and the front part of the sheet passes from the table 2 on to the table 3 before abutting the stop which serves to position the sheet but takes no part in the buckling operation. It is then gripped at one side of the rollers 5, 6 between a fixed bar 8 and a movable bar 9 carried by a pivoted lever 10, and at the other side between a driven roller 5 mounted on a fixed shaft and a roller 17 carried levers 16 pivoted on brackets 15. The movement of the bar 9 is derived from a cam 14 through a lever 13 and link 12, and the movement of the roller 17 is derived from a cam 20 on the shaft of the cam 14 through a lever 19 and link 18. A guide bar 21 carried by the end of the levers 16 serves to ensure that the sheet is buckled in the direction of the rollers 5, 6, and the sheet is released by the bars 8, 9 and rollers 5, 17 as soon as it is gripped by the rollers 5, 6. The folded sheet may be, directed over a guide, to a conveyer band 22 or may pass to apparatus for further folding. In a modification, the bar 9 is carried by the levers 16 and is shaped so as to take the place of the guide bar 21. In place of the inclinedroller table 3, conveying bands are used. In another form, Fig. 4, a roller 26 always in engagement under gravity with the roller 5 takes the place of the roller 17, and a roller 25 carried by a lever 27 and adapted to engage with the roller 6 as soon as the sheet has contacted with the front stop serves to buckle the portion between the pairs of rollers 5, 26 and 6, 25 respectively into the bite of the rollers 5, 6. The roller 6 is arranged slightly below the place in which the sheet is fed so as not to interfere with the movement of the sheet along the table 3 to the stop. Pivoted fingers 28 resting on grooves in the roller 6 are moved upwardly for this purpose also, and are carried by a lever 30 connected by a link 31 to the lever 27 which is actuated from a cam 14 through a lever 13 and link 12 as in the case of the bar 9.

Title: Apparatus and method for chromatographic analysis
IPC: G01N30/50
Filed: 1965-01-27
Abstract: 1,086,771. Gas chromatography. UNIVERSAL OIL PRODUCTS CO. Jan. 27, 1965 [Jan. 28, 1964], No.3502/65. Heading G1N. The sensitivity of a gas chromatographer is improved by utilizing in the separating column a solid sorbent selectively sensitive to the components of a mixture, and two thermal conductivity elements, connected in a bridge circuit, separated by a delay element, whereby the base of the eluent curve is automatically maintained at the zero value of the unsorbed gas component. As shown (Fig. 1), a separating column 37 for the chromatograph contains a solid sorbent, chosen to be adsorbent to one component of a gas mixture. Selected gas, as determined by a sampling valve 10, is fed through the column 37 to a reference thermal conductivity cell 38, a delay element 39, and a measuring thermal conductivity cell 40. Initially, with valve 10 as shown, carrier gas from a supply 32 is fed through the above elements, and the measuring bridge containing the temperature-sensitive resistors of the reference and measuring cells in opposite branches, is balanced. Valve 10 is then operated, by applying pressure to move it downwards, and a sample of test gas mixture located in port 18 is pushed through the system by the carrier gas. The sorbed component is initially removed in the column 37, and the unadsorbed component produces a positive peak reading from the bridge circuit when the gas reaches the measuring cell 38, followed by a negative peak when it reaches the reference cell 40. After a time the sorbent in column 37 is saturated with the adsorbable component of the gas mixture, and this component is then eluted continuously. Thus the output from the bridge between the two peaks representing the unsorbed component is representative of the adsorbable component, but since it affects both cells 38, 40 continuously the nett effect on the bridge output is nil, and only the peaks due to the unsorbed component are recorded. The sampling valve 10 and the chromatograph units 37-40 are located in temperature controlled boxes 25, 42, 43. The apparatus may be used with a mixture containing more than one non-adsorbed gas. If the chromatograph temperature is sufficiently high, all these gases are eluted together, producing one pair of elution peaks for the whole group. The sampling valve 10 may be programmed to operate cyclically.
