Title: Process and apparatus for separating gaseous mixtures
IPC: B01D53/04
Filed: 1970-06-08
Abstract: 1311360 Separating gas mixtures PROCESS SERVICES Inc 8 June 1970 [17 June 1969] 27556/70 Heading B1L In a 3-bed process for the separation by adsorption from a gas stream of 2 or more components which have substantially different adsorption bond strengths, desorption is carried out in two successive stages, firstly by pressure swing regeneration and thereafter by thermal regeneration. Thus, natural gas from which CO 2  H 2 S and water vapour are to be removed are passed by line 6 to on-stream absorber A, purified effluent leaving through valve 13 and lines 14, 16. At the same time, adsorber B is being pressure desorbed by means of neutral gas, e.g. with N 2  or dry natural gas, introduced by line 20' through valve 19', the effluent being vented through valve 17'. When pressure regeneration of adsorber B is complete, B is brought on-stream and adsorber A is pressure regenerated. Meanwhile, during the period when adsorbers A and B are alternately coming on-stream and being pressure regenerated through a number of cycles, adsorber C is being thermally regenerated by means of a heat exchange fluid circulating through heating coil 22', purged effluent passing out through vent 17". At the end of this thermal regeneration period, adsorber B is taken out of the alternating cycle and subjected to thermal regeneration, while beds B and C alternate in the adsorptionpressure desorption functions. In another embodiment (see Fig. 2, not shown), pressure desorption is achieved by applying a vacuum, and thermal desorption is performed by heating a sidestream of the product effluent, backflushing the adsorbent bed with it, and passing the effluent stream back into the process supply line. The process may also be applied to the separation of mercaptans, alcohols and acetylenes from hydrocarbon mixtures; the separation of CO and CO 2  from combustion gases; SO 2  and H 2 S removed from process waste gas; removing CO 2 , HC1 and water from fluorocarbons; removing CO 2  and water vapour from steam reformer gas containing CO; and removing SO 2  and H 2 S from gas consisting chiefly of CO 2 . In the embodiments described above, the adsorbent is suitably a zeolite, but the process is also applicable to silica gel and activated charcoal adsorbents.

A roll of photographic film comprises a flexible support strip coated on one surface with a photographic emulsion, and provided with a series of perforations for engagement by a metering member in the camera, the other surface of the support strip having a backing strip attached thereto; the area of the backing strip adjacent each perforation has a plurality of slits, so disposed that the end of the metering member can extend therethrough without permanently impairing its light-protective function. Fig. 2 shows the support strip from the non-emulsion side, with 'the backing paper removed. On the emulsion side are a series of light sensitive areas 17, each in the same relative position to a respective metering perforation 18. The marginal area 32 is used for film identification. When the backing strip is in position, the part covering each metering perforation has a series of slits 24, as in Fig. 4 or Fig. 5. Further possible arrangements of slits are as in Figs. 6 and 7 (not shown). The metering pin can thus pass completely through both the perforation and the backing paper, temporarily distorting the backing paper without permanently impairing its light sealing function. Specification 965, 532 is referred to.

Title: Manufacture of convoluted tubing and bellows
IPC: B21D15/06
Filed: 1973-06-12
Abstract: 1418542 Corrugating tubes UNITED FLEXIBLE METALLIC TUBING CO Ltd 29 Aug 1974 [12 June 1973] 28025/73 Heading B3E Apparatus for corrugating tubing 1 comprises an arbor 5 having a free end mounting at least one roller 7, 8 for engaging inside the tube, and a mandrel 6 carrying the tubing and having a free end opposite that of the mandrel, wherein a chuck 14 is provided to rotate the tubing relative to the mandrel, and a support is provided at the free end of the mandrel offset from its axis and on the axis of the rollers, which detachably engages the free end of the arbor. Bending moments on the arbor are thus relieved. The mandrel and arbor may rotate, the tube being stationary, or as in Fig. 1, the arbor is held stationary on a tailstock 3 while the tube and chuck 14 are rotated in a headstock 2 through which the non-rotary mandrel 6 passes. The arbor 5 is slightly pivotable at the tailstock by a fluid pressure jack 48, and movable axially by jack 44. The whole tailstock can be pivoted with the arbor. The mandrel is movable axially in either direction by jack 32 through a lost motion connection 36, 38, 39, and can be urged towards the arbor by jack 31. The two rolls 7, 8, Fig. 2, are mounted on a shaft 49 located in the end of arbor 5 by a pin and slot coupling 50 and urged apart by spring 53. A head 51 on the shaft is engageable in a recess 52 in a plug 18 on the end of the mandrel. A sleeve 20 is located on the plug opposite chuck 14, the jaws of which are shaped to engage a partially corrugated tube 1, and which is releasable manually but engages itself automatically. The outer roller 9 on fixed shaft 57 is of snail cam shape, and has a cut out to clear the tube 1. In operation, the arbor and mandrel are disengaged by jack 32, and the arbor and tailstock are swung aside to allow a partially corrugated tube to be fed on to the mandrel, chuck 14 being manually held released. The chuck is then allowed to grip the tube on to sleeve 20. The arbor and mandrel are then swung back, and engaged by jack 32. The tube is rotated by chuck 14, and roller 9 turned by hand so that it engages the tube, whereafter it is driven by the tube, and forms a deepening corrugation in the tube. The two rollers 7 and 8 are moved towards each other meanwhile by jacks 44 and 31. Roller 9 stops when the cut out reaches the tube, then the arbor can be pivoted by jack 48 to clear the corrugation, so that the tube can be inclined forward for the next corrugation to be formed similarly. In the embodiment of Fig. 4, the tailstock 62, arbor 65 and inner rollers 67 are similar, but there are two outer rollers 72, 73 mounted on coaxial shafts 74, 75 on a cross-slide 69 movable tranversely to the axis of tube 60 by a cam drive 70. The required axial movement of roller 72 as it is moved radially to form a corrugation is obtained by lever 79 pivoted on slide 69, bearing on a fixed incline 81 at elbow 80 and bearing at its free end on a cap 82 to move the roller shaft 74 against spring 78.

Title: Improvements in electrical voltage regulating systems
IPC: H02H7/06
Filed: 1948-10-28
Abstract: 649,560. Automatic voltage control systems. GRAY, A. H., FENWICK, D. R., KUYSER, J. A., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Oct. 28, 1948, No. 28039. [Class 38 (iv)] An automatic voltage regulator, e.g. for an alternator, is disconnected if the voltage applied to the measuring coil falls due to a fault in the measuring apparatus, but is not disconnected if the fall in voltage is due to a fault on the system. Contacts 16a disconnecting the regulator 8 are opened by relay OC16 which is connected across an auxiliary supply in series with the normally closed contacts 13a, 14a, 15a of current responsive relays OC13, OC14, OC15 and the normally open contacts 12a of a voltage responsive relay OC12 connected across the measuring coil of the voltage regulator. If the measured voltage falls below a predetermined value, contacts 12a close and operate the disconnecting relay OC16. If, however, the fall in voltage is accompanied by a current surge in the main system, then one or more of the current relays operate to open the circuit of relay OC16 and prevent its operation. The current relays also energize holding in coils HC13, HC14, HC15, and a time delay relay OC19 which releases the holding coils after a suitable delay. In a modification, Fig. 2, (not shown), the time delay relay is omitted and a further pair of contacts on a field forcing contactor are arranged to delay the de-energization of the holding coils. In a further modification, an extra voltage sensitive relay replaces the contactor contacts.

Abstract: 482,803. Snap-action switches. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. Oct. 15, 1937, No. 28049. Convention date, Oct. 21, 1936. [Class 38 (v)] An electric switch with a number of contacts' 7 has a blade 11 which moves from one contact to the next with a snap action imparted to it by a spring 13, which, after being stressed by the operating means 15, detaches the blade from engagement in a latch plate 9 and causes it to rotate to the next contact. In Fig. 1 an insulating base 5 carries spaced contacts 7, in engagement with one of which is the switch blade 11. This blade 11 is located bv the spindle 31 which also carries the spring 13, but an elongated slot 53 allows it a limited longitudinal movement, and the spring ends 65 pressing on lugs 60 and 61 of the blade 11 cause a projection on the part 57 of the blade to engage in a notch 41 of the latch plate 9 which is fixed to the base 5 and carries a terminal 45. The operating member 15 shown in Fig. 3 is mounted on the spindle 31 and when rotated in a clockwise direction by a handle 79, the edge of a flange 75, engaging the top end 65 of the spring 13, pulls it round to stress the spring until it reaches that lug 60 on the blade which is nearer the contacts 7, when the blade is pulled from engagement with the latch plate 9 and is speedily rotated under the action of the spring until, when the blade engages the next contact 7, it also engages the next notch 41 in the latch plate. Operation in the reverse direction is effected similarly, a projection 77 on the operating member 15 engaging the lower end of the spring 13.
