Title: Gas chromatographic apparatus
IPC: G01N30/20
Filed: 1962-11-07
Abstract: 1,014,877. Sampler for gas chromatography LEEDS AND NORTHRUP COMPANY. Nov. 7, 1962 [Nov. 7, 1961], No. 43996/64. Divided out of 1,014,876. Heading B1L. In a gas chromatographic apparatus, a restricted flow connection for the carrier gas is in communication with the column at all times. A sample introducing means is provided which includes a fixed volume chamber, flow connections adapted to be cyclically completed alternately to cause the sample stream to flow through the chamber and to cause carrier gas to flow in parallel with the restricted flow connection through the chamber and thence to the column. In a specific embodiment, Figs. 1 and 2, explosion proof housing 11 surrounds casing 12 which houses the chromatography column 13 and sampling valve 20. The space between 11 and 12 may be heated or purged by introducing air at 21 which is vented at 22. Carrier gas, e.g. He, is introduced from cylinder 15 by way of preheating coil 14 to the sampler entering at pipe 48 passing detector 33 through restriction 49, and pipe 47 to the column 13, whence it flows past detector 30 and out through throttling valve 31 and line 32 to the atmosphere. Sample gas flows in through line 25 and preheater 28 to sampler 20, flowing through tubes 52, 53, 42 and 54 back into 52 and out through 29. The restriction 55 ensures that the sample gas must pass through the tube 42 which is of predetermined volume and housed in the rotatable part 20r of the sampler 20. A sample is introduced into column 13 by rotating 20r by means of pin 39 acting in slot 38a so that the pipes leading to tube 42 are aligned with pipes 46 and 47 and thus the sample is swept out by the carrier gas. Part 20r of the sampler is held on the working surface of 20 by a spring which acts on axle 36, plate 40 and bearing 35, the upper surface of 20r being made of P.T.F.E. to give good sealing contacts. To purge the column rapidly, valve 31 is provided with a by-pass connection which allows gas to flow freely to the atmosphere instead of through the valve. The by-pass connection may even by-pass the measuring cell 30.

Abstract: 1389886 Surface modification of rubbers NIPPON ZEON CO Ltd 25 Sept 1972 [27 Sept 1971] 44202/72 Headings C3E and C3P A shaped article whose surface is composed of a natural or synthetic rubber containing ethylenic double bonds is contacted with an alkyl or haloalkyl hypohalite in order to reduce friction and improve the ozone resistance of the rubber. Preferred hypohalites are tertiary alkyl, especially tertiary butyl, hypochlorites and hypobromites. They may be used neat or in solution, preferably in a solvent which swells but does not dissolve the rubber, e.g. benzene. Exemplified rubbers are natural rubber and polybutadiene, acrylonitrile-butadiene, ethylene-propylenediene, isobutylene-isoprene and styrene-butadiene synthetic rubbers, each rubber being vulcanized and formed into sheets for the surface treatment.

Abstract: 1,048,650. Toothed intermittent gearing. VEEDER INDUSTRIES Inc. Nov. 12, 1963 [Nov. 23, 1962], No. 44625/63. Heading F2Q. [Also in Divisions G3 and G4] In an intermittent drive mechanism connecting a driven wheel 18 with a wheel 16 drivingly supported by an input shaft 14, e.g. in a clock or counting device, a mutilated pinion 60, freely rotatable on an eccentric hub 62 of the wheel 16 and having axially shortened teeth 102, 104, meshes with an internal gear 65 in the wheel 18. A spring 67 passing round a collar 74 rotatable on the hub 62 connects a pin 68, on an arm 100 integral with the pinion 60, to a lug 70 on an arm 72 secured to the collar 74 to urge the arms 72; 100. against shoulders 82, 84 respectively, formed in the mutilated internal gear 66 of a fixed plate 24. As the wheel 16 rotates, the pinion 60 moves from a datum position (Fig. 4) to mesh first with a tooth 106 and then with a tooth 108 of the internal gear 66, thereby rotating the pinion 60 anti-clockwise, Fig. 4. When the pinion 60 ceases, to mesh with tooth 108, the spring 67 causes the pinion to spring back to the datum position, imparting an impulsive drive to the previously static wheel 18 without affecting the input shaft 14. In a second intermittent drive mechanism (Fig, 2, not shown), between wheels 18 and 20, as the wheel 18 rotates, a mutilated pinion 40 rotatably mounted eccentrically thereon planetates about the wheel's axis of rotation in mesh with substantially identical internal gears 44, 46 respectively formed in a fixed plate 26 and the wheel 20, the gear 44 having a section 48 formed by the omission of two teeth, the wheel 20 remaining stationary except when the pinion 40 crosses the section 48, when a projection 50 on a fixed plate 25 prevents rotation of the pinion 40, causing the wheel 20 to be driven. Both forms of intermittent drive are used in a twelve-hour clock, Fig. 1, having an hours wheel 22, a minutes tens wheel 20, numbered from 0 to 5 twice, a minutes units wheel 18, and a seconds wheel 16 displaying time intervals of six seconds, wheels 18, 20 and 22 being rotatably carried by the input shaft 14. Fixed plates 10, 12, 24-28, are connected by a circular rod 36 and hexagonal rods 29 having reduced portions 31 engaging in slots 32 of the plates.

In an exchange of the No/ESS type, ringing current and tone are supplied to a plurality of called and calling parties on a time division multiplex basis. The " time slots " are normally of 2 sees. duration with a periodicity of 6 sees., i.e. three parties can be " simultaneously " rung but in the event of overload the duration may be reduced or the periodicity increased. Particular description.-An incoming call (inter or intra office) to trunk circuit TF say is detected by ferrod scanner FS1 whereafter incoming digits representing the called party are received and stored in central control CP. A connection from the called party-assuming he is idle-via a ferreed line-link network (not shown) and the trunk-link network TLN to the trunk circuit TF is set up on instructions supplied from the central control to the network controllers such as NC1. Thereafter at the beginning of the ringing time slot allocated to TF, NC1 supplies an earth pulse on lead NCF which brings up relay RF (Fig. 4) to effect line splitting and RR (Fig. 5) to enable the ringing control circuit RCC. In the latter, relay chain WA-ZC, CT and normally energized RTA determine the interval for which ringing should be supplied and at the end of the interval (2 sees. normally but less if more than three lines are to be rung as indicated by B or B and C being up) they bring up TO to cut-off the supply of ringing by releasing RR and RF. If the called party does not reply within 6 sees., central control brings up RR, RF again at 6 sec. intervals until the party does reply (detected by ferrod scanner FSO) or the caller hangs up (ferrod scanner FS1). If the party replies during a ringing burst, ring trip relay RT operates to release the ringing control circuit (RTA falls back) and cut-off the ringing (RR, RF fall).

When the plunger is forced into the cylinder the air 16 is compressed. The damping means may comprise a piston 18 on the plunger in an oil chamber 17, and which is provided with oil flow holes or valves 19. The degree of damping may be dependent on the position of the piston in the cylinder, thus: (i) by provision of a further piston 22 having oil flow valves 23 and which acts as an additional damper only when it is inside the restricted portion 24 of the cylinder; (ii) by a similar arrangement wherein the oil flow is instead via a channel by-passing the piston and which connects the restricted and unrestricted portions; or (iii) by providing the cylinder with a wider portion (28, Fig. 3) at its top whereby no damping effect is obtained when the piston is in this portion. The valve 19 may be adjustable (Fig. 5) by means of an axially displaceable tapered valve body (35) operated from externally via a rod (37) in an axial bore of the plunger. As exemplified the spring is used in a door closing device (see Division E2).
