Title: Improvements in or relating to the treatment of liquefied petroleum gas
IPC: C07C7/148
Filed: 1951-12-31
Abstract: Liquefied petroleum gas such as propane or butane or mixtures thereof containing more than 1 p.p.m. of free sulphur is purified by contact with a solution of alkali metal hydroxide containing a small amount, e.g. less than 5 per cent. by weight ethyl or methyl mercaptan.  An amount of 0.8 - 4 per cent. is satisfactory.  The temperature is generally about 40-120, e.g. 70-90 DEG F.  The hydroxide should in general be sufficient to give a pH above 8.5, 10 per cent. sodium hydroxide being suitable.  Potassium or lithium hydroxide is also of use, and the amount may range from 5-30 per cent. by volume of the liquefied gas.  The mercaptan may be extracted from the liquefied gas itself.

Title: Electronic telephone system
IPC: H04Q3/52
Filed: 1974-07-10
Abstract: 1471364 Automatic exchange systems STROMBERG-CARLSON CORP 10 July 1974 [9 Jan 1974] 30569/74 Heading H4K A telephone exchange comprises a plurality of input/output circuits, a plurality of junctor circuits, a switching matrix in the form of a rectangular array of horizontal and vertical lines and electronic switch means for selectively effecting interconnection between a horizontal and a vertical line at each crosspoint thereof in response to a control system, said control system being adapted to close two crosspoints associated with the same vertical to interconnect two input/output circuits. In the PABX shown the crosspoints of the matrix 10 are pairs of saturable transistors as described in U.S. Specification 3,789,151. Only speech, tone dialling, tone transmission and music distribution from a supply 82 are transmitted through the switch. Off-hook signals, dial pulses and ringing signals being conveyed to and from the common control via an external common bus from or to that line (line 1 to line 12) or register sender 1 to 5 which is being addressed by the matrix. The common control operates with 32 time slots associated one with each of 32 junctors such as 80 connected to the verticals of the matrix and two additional time slots used for signalling and in which one line per 34 slot frame is addressed. Tones such as dialling tone and music can be coupled to the junctors and thus to the subscribers via an additional matrix shown at the foot of the Figure. During each time slot the crosspoints associated with the corresponding junctor are all simultaneously addressed. Those which are to be or remain closed are also further enabled by a row marking any other crosspoints of the addressed column are automatically released. Thus any incorrectly operated crosspoint is corrected during the next cycle. Some subscribers have multi-frequency diallers and a class of service unit 47 indicates when such a subscriber initiates a call. The subscriber is connected to a tone receiver 40a to 40n which generates impulses over the common signalling wire. In the case of an outgoing call the local junctor initially taken into use is released and a trunk junctor connected into circuit. The operator equipment 60a to 60n, 65 and 70a which has a coupon facility 75 and a conference circuit 55 are connected on the subscriber side of the matrix and no line splits are required. Vague mentions of an intercept recorder 50, a code call circuit 25, dictation stations 20a to 20n, statistical recorders 17, and indicators to indicate the number of a called line so that another subscriber can answer the call are included.

A sealing device for preventing the passage of fluid under pressure through an opening 5, Fig. 1, in a wall 4 through which a rotary shaft 1 extends comprises an expansible annular bellows 11 which surrounds the shaft on the side of the wall remote from the fluid and has radial end walls 15, 16 connected at their outer edges by a flexible external wall 18, the arrangement being such that fluid passing through the opening to the bellows causes one or both end walls 15, 16 to move axially and so exert a sealing effect. The bellows shown in Fig. 1 has two corrugations formed by an encircling ring 19 and is supported between two rigid discs 24, 26. An axially-extending flange 20 on the end wall 15 has a lip 12 for engaging a shoulder 6 in the opening 5; a corrosion-resistant covering 7 is provided on the wall. The inner end of the disc 26 is formed to provide a sealing face 13 to co-operate with a carbon collar 14 which is clamped inside a Z-section deformable ring 31 itself clamped on the shaft. The shaft is centred in the opening 5 by a bush 21 having a clearance space 23 through which fluid passes to the interior of the bellows through apertures 30 in a ring 29 serving to prevent collapse of the bellows; the fluid pressure in the bellows moves both end walls 15, 16 so as to cause the lip 12 to seal against the shoulder 6 and the face 13 to seal against the collar 14; the axial flange 20 on the wall 15 is also urged radially so as to force the lip against the opening 5. In the embodiment shown in Fig. 2, the bellows 41 is secured by a band-clip 48 to the shaft 1 to rotate therewith and carries a carbon collar 44, secured by a band-clip 57, within an axial flange 53 of the bellows. The contact face 59 of the collar 44 bears on the face 60 of a wedge-shaped ring 43 which engages an O-ring 42 disposed in the operiing 5. Fluid passes to the interior of the bellows through a clearance 64 in the ring 43; grooves 52 are provided in the face of a stop flange 51 on the bellows to admit fluid to the latter in the event of this face being in contact with the opposite end wall of the bellows. In the embodiment shown in Fig. 3, the bellows 71 has an axial flange 77 held in sliding engagement with the opening 5 by a bush 81 having a conical face 82 which engages a lip 72 formed on the flange 77. A sealing ring 73 is secured within a recess in a second flange 88 of the bellows by a band-clip 89 and fluid pressure in the bellows moves it axially into sealing engagement with a ring 74 which is clamped on the shaft by a resilient Z-shaped member 92, secured to the shaft by a band clip 96. The sides 75, 76 of the bellows are reinforced by discs 78, 86, situated in grooves 79, 87 in the flanges 77, 88. In each embodiment, the parts exposed to contact with the fluid to be sealed are made of corrosion resistant material and the shaft 1 may be coated with similar material.
