Title: Process and apparatus for the separation of water and impurities from steam
IPC: B04C7/00
Filed: 1962-10-08
Abstract: 953,686. Centrifugal separators ; contacting gases with liquids. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Oct. 8, 1962 [Oct. 10, 1961], No. 38074/62. Headings B1R and B2P. Steam containing water and solid impurities, such as water-insoluble salts and metal oxides, is separated into dry steam, pure water and water containing impurities by supplying the steam, through a tangential inlet 2, to the interior of a centrifugal separator 1 where, after initial separation, the steam is passed through a liquid screen of purified water in which the remaining impurities and some of the remaining water are caught, the steam being then led through a cyclone 4 provided in the separator above the screen and from which dry purified steam is discharged overhead and water is discharged via a pipe 22 in the bottom of the separator 1 into a water zone 7 where separated water and water from the liquid screen are passed through a central passage inside an annular space 5 provided above the zone 7 and beneath the inlet 2 and in which separated impure water with the highest concentration of impurities is collected. The liquid screen is provided by the purified water being fed through a line 10 either into an annular channel 3 and overflowing therefrom or to a closed perforated circular pipe. The remaining water particles containing the remaining solid impurities are agglomerated to form larger drops in the liquid screen and, as they travel down the separator, are whirled round by the incoming steam and flung outwards against the wall of the separator where, together with the initially centrifugally separated water and impurities, they are collected in the annular channel 5. The impure water is removed from the channel 5 by a line 11 while water substantially free of impurities flows over the upper edge of the channel into the zone 7. The cyclone has a tangential inlet 14 and a steam discharge pipe 15, which may be surrounded by a water collecting baffle 16 and which opens into an additional water-separation chamber to which is connected the purified steam discharge line 9 and a water discharge pipe 24. Supported on the flat bottom of the cyclone is a catch pot 18. Baffles 20 are provided externally of the catch pot to counteract rotation of the gases while allowing separated water to flow freely down the cyclone wall. Particles of water entrained by the gases towards the centre of the cyclone pass into the catch pot where they are removed by a pipe 23 tangential to its flat bottom. The pipe 22, which is also tangential to the bottom of the cyclone, together with the pipes 23, 24 discharge either directly into the space 7 or, preferably, as shown, into a box 6 serving as a liquid seal. The pure water may be returned to a steam boiler to which the separator is connected.

Abstract: 1330547 Counting apparatus; credit accumulating NSM-APPARATEBAU GmbH KG 18 Aug 1971 [2 Sept 1970] 38733/71 Headings G4D and G4V A device for calculating and registering a credit balance, for example in a gaming or vending machine, has one or more number wheels 5 registering monetary values, each value on the wheel being associated with a memory device S 0 -S 0 , on the wheel, which can be energized by an adjacent fixed unit E responding to a designated value of coin being inserted in the machine, and an electric motor which is energized, on insertion of the coin, to drive the wheel until the so energized memory device S reaches a datum position beneath a viewing window 1. Thus if a 50 unit coin is inserted into a coin shoot (20) (Fig. 3, not shown) a contact (19) causes unit E 0 , 50  to energize the adjacent memory which is S 6  in the position shown and a relay (M) to energize the motor (18); the relay also closes self holding contacts (m) which are interrupted as the memory S 6  reaches the datum position where its detected and then erased by a pick-up 17; the wheel has thus rotated to indicate an increase of 50 units in the credit. By reversing the motor the credit is reduced. With several number wheels (Fig. 1, not shown) each may be driven as above, accommodating large denomination coins, or alternatively only the lowest denomination wheel is driven by the motor and the other wheels by suitable transfer mechanism.

Abstract: 369,970. Looms with automatic weft replenishing mechanism. PLATT BROS. & CO., Ltd., Hartford Works, Oldham, and TOYODA, K., Shirakabecho, Nagoya, Japan. Dec. 24, 1930, No. 38825. [Class 142 (iii).] Shuttle - changing mechanism.-In a loom wherein a fresh shuttle, forced from the magazine, passes between a front plate and a guide plate and pushes a spent shuttle from the shuttle box, the back plate l of the shuttle box is carried by the front plate whilst the latter and the guide plate k, are formed with oppositely curved surfaces, symmetrical in form and disposition, to prevent the shuttle from tilting about its longitudinal centre line during transfer. The front plate j and guide plate k are supported by pairs of arms n, q respectively, pivotally mounted on studs o secured in brackets q on the sley and are urged towards one another by independently mounted springs r, v, the former being coiled about the studs o and engaged by the arms n whilst the latter are located between bearing rollers s and adjusting screws w in tubular guides u carried by the sley. A spring influenced buffer z, in the form of a bar which extends longitudinally behind the shuttle box and carries a resilient pad 1, is pivotally mounted on studs y on the sley and is provided with projections 2 to bear against the inclined surface of stops 3 fixed upon the arms m which support the back plate. When the shaft 8 is rocked consequent upon weft failure and the transferrer is operated as a result of the bunter 12 engaging a raised arm 11, a shuttle x forces apart the front plate and the guide plate and raises the back plate l to allow the spent shuttle x<1> to be pushed out. As the back plate is raised however, the stops 3 are moved away from the studs 2 and the buffer z, under spring influence, turns in an anticlockwise direction to engage and, in co-operation with the shuttle x, to hold the ejected shuttle until the fresh shuttle is properly inserted in the box. When the shuttle x is correctly positioned the front and guide plates return to normal position and the back plate pushes away the ejected shuttle, the stops 3 again engaging the projections 2 to withdraw the buffer.

Title: Automated means for determining subsurface velocities from seismograms
IPC: G01V1/30
Filed: 1969-08-04
Abstract: 1282936 Seismic velocity determination MOBIL OIL CORP 4 Aug 1969 [14 Aug 1968 22 Oct 1968] 38947/69 Heading H4D An automated trace-searching procedure is used to determine the seismic velocity characteristic of the earth from a set of seismic traces. The traces may be derived from respective detection spaced along a survey line in either a common depth point or "end-on" shooting method. In the Fig. 3 example, traces 1 to 24 are searched for the presence of a seismic wavelet in a time window W 1  of duration corresponding to the anticipated wavelet duration. The window for trace n commences at a trace time t xn  displaced from a given vertical travel time T 0  (i.e. the time on the trace from a detector with zero source-to-detector offset) by an amount predicted using the known detector offset value X n  and an assumed velocity value V 1 . The searching is repeated for other windows W 2 , W 3  etc. using different assumed velocities V 2 , V 3  etc., and the value of V giving the maximum detection of wavelets is taken as the actual velocity. The searching steps are then repeated for other values of T 0 . Allowance may be made for possible dip of the subsurface when predicting the values of t xn , by repeating the above searching steps for each of several assumed dip values and taking as the most probable dip the value which gives maximum detection of wavelets. Wavelets may be detected either by summing the amplitudes of those trace portions appearing in a window, or by a zero-lag cross-correlation technique in which a function representing signal power is derived by multiplying each trace portion in the window by the window portion of all other traces and summing the resulting products. Signal power may be plotted as a function of assumed velocity for each of the time T 0  to give a set of curves (Fig. 5) the positions of whose peaks represent the actual velocity distribution in the earth. By plotting peak signal power as a function of T 0  for each of several assumed dip values (Fig. 6) the most probable dip can be determined. Details, including a programme, are given of a digital computing system for the trace-searching procedure.
