Title: Process and apparatus for the desalination of water
IPC: C02F1/04
Filed: 1970-07-02
Abstract: 1279893 Desalination of water by distillation and reverse osmosis STONE & WEBSTER ENG CORP 2 July 1970 [17 Sept 1969] 32175/70 Headings B1B and B1X Saline water is desalinated by passing a stream of it to an evaporator and removing distillate therefrom, passing a second stream of the saline water into heat-exchange relation with vapours evolved in the evaporator and then, at elevated pressure, to a reverse osmosis system from which partially-desalinated water is withdrawn, and is combined with the distillate from the evaporator. The flow rates to the two desalination systems can be adjusted to obtain any desired salt content in the combined product. In the apparatus shown, sea water is pumped, via lines 10 and 16, through the condenser tubes 17 of the last stages of a multistage flash evaporator 18, and then divides into two streams. A minor stream 19 flows through deaerator 20 and then flows into the last flash chamber whence brine is pumped through condenser tubes and heat exchanger 112 into the first flash chamber of the evaporator. The major stream 21 is pumped to three-stage reverse osmosis system 38, 48, 80. The waste brine 54 from the first unit 38 drives a hydraulic turbine 56 connected to the pump 36 for feeding sea water to unit 38, the speed of the turbine being controlled to maintain a constant pressure (e.g. 900 psig) in the unit by means of controller 60. A major proportion of the partially desalinated water 40 produced by unit 38, the salinity of which water is automatically controlled, is pumped to the second unit 48, and the remainder flows to product sump 84. The partially desalinated product water 74 from unit 48 flows to sump 84; and the brine 76 is pumped to unit 80. The partially-desalinated product water 74 from unit 48 flows to sump 84; and the brine 76 is pumped to unit 80. The partially-desalinated product of unit 80 flows to sump 84; and the brine 88 is pumped back to unit 38 through line, 91. Some of the distilled water 22 produced by the evaporator is mixed with the product withdrawn from sump 84, and the remainder is passed to deaerator 118 and highpressure steam generator 26. Some of the pumps are driven by turbines 92, 94, 96, 98, 106 which are supplied with steam from generator 26 via line 99. A turbo generator 100 is also supplied with steam from line 99 and provides electric power for driving some of the pumps. Exhaust steam from the turbines and the turbo-generator 100 is supplied through line 103 to the heat-exchanger 112 of the evaporator. A multiple effect evaporator or long tube evaporator may be used in place of a multi-stage flash evaporator.

Title: Improvements in or relating to permanent moulds
IPC: B22C9/06
Filed: 1939-12-14
Abstract: 537,295. Casting-machines ; moulds. STONE & CO., Ltd., J., and LEWIS, E. C. Dec. 14, 1939, No. 32219. [Class 83 (i)] Casting processes ; casting composite articles.-In casting articles wherein considerable variations in section occur in permanent moulds, those parts of the mould or core producing thin sections are detachably mounted in such a way as to avoid loss of heat. A metal mould for casting a cylinder head 6 with fins 7 comprises two mould halves 1 which extend to form a runner 2, long enough to give a sufficient hydrostatic head, a chamber 3, large enough to hold all the molten metal required for mould and runner, and a support 1b for a plate 22 which carries core plates 10, Fig. 2, to produce the fins 7. The core plates are integral with mould sectors 9 with T-slots 11 which are engaged with inverted T-section rings 12, 13 each formed in, e.g. four, segments. The upwardly extending parts of these rings are thickened and engage segments of a dovetail ring 14 having bolt holes adapted to be engaged by bolts 18 of a carrier 16, a gap 19 being left to avoid loss of heat by the plates 10. The carrier has a hollow stem 20 in which is mounted a core 29 carrying a sand core 28 and which slides in the plate 22 This carries a shaft 26 and pinion 27 for withdrawing the core plates 10, after casting and detaching the sand core at 32, by engaging rack teeth 25 in the stem 20. The core 28 may have a metal socket 31 to engage its holding screw 30 and another 33 to support a machined part 34 to be cast into the body 6. To avoid damage to the fins by withdrawing all the plates 10 simultaneously alternate sectors 9 may have recesses 11<SP>1</SP>, Fig. 2, formed therein so that they only commence to move after the other plates 10 have been stripped. Pouring is effected by turning the device in a clockwise direction about trunnions 37 through 90 degrees and the position shown is reached. 38 is a mould-piece for forming a lug 39 on the casting. In a modification the mould remains stationary and the runner 2 and chamber 3, Fig. 3, are jointed at 50 to the mould gate and swing about the axis y to bring the runner into a horizontal position so that the chamber can be charged and then into the position shown for pouring. The joint 50 is kept tight by a spring s and the runner halves are turned about a pivot 43 to separate them after casting and are then withdrawn on a slide 49. An artificial head can be produced by applying pressure to the metal or a vacuum to the mould during and after casting.

Title: Method and device for adjusting the wall thickness of plastics articles
IPC: B29C48/92
Filed: 1972-07-11
Abstract: 1396538 Controlling extruded tube wall thickness INDUSTRIELE ONDERNEMING WAVIN NV 11 July 1972 [16 July 1971] 32432/72 Heading B5A [Also in Division G3] The wall thickness of an extruded plastics tube is controlled by selectively switching auxiliary heaters around the circumference of the extruder head in response to devices which sense the thickness at corresponding points around the tube. The sensors 10 comprise twelve equally spaced switches, each consisting of a flat metal plate guided in a plastics support and urged outwards against the extruded tube within a sizing die 9 by an air filled "balloon". Each plate has projections at both ends which complete a circuit through "fixed contacts" when the thickness is a desired minimum. Short term fluctuations are ignored because these influence the contacts at one end only of each plate at a time. The heaters are in the form of plugs 26 in the extruder casing 3 and/or wires embedded in slots in both the casing and the core 2, and each is turned off (by a relay) when its corresponding switch is opened. Opening of a switch also causes cooling air to pass through a corresponding channel 30 for a finite time, e.g. 10 seconds, determined by a single timer. This arrangement is to eliminate eccentricity, which results in a number of switches being opened in sequence; the single timer shuts all the air ducts off together and thus the sector whose switch opened first receives cooling air for the longest time. Four switches at 90 degrees to each other also control a motor drive (Fig. 8, not shown) which draws the extruded tube. Initially, this drive gradually decelerates, causing thickening of the tube wall; when this is detected by simultaneous opening of the four spaced switches a servomotor causes the drive to gradually accelerate until the four switches again close and the cycle is repeated.

Title: Improved diluent purification process
IPC: C07C7/10
Filed: 1959-09-24
Abstract: A hydrocarbon diluent used in a low pressure polymerisation and containing alkanol and a chelating agent is purified by separating from the alkanol by distillation, washing with aqueous caustic alkali and separating and then water and separating and drying by azeotropic distillation.  The azeotrope overhead from the azeotropic distillation is preferably returned to the separating step following the water washing.  The hydrocarbon may be isopentane, cyclohexane, heptane, benzene toluene or xylene and is contaminated with a C1-C8 alkanol and acetylacetone or diacetyl.  The caustic solution may be of 0,1-20% wt. strength and is used in amounts of 10-200% wt. based on the hydrocarbon.  Of the separated caustic solution, 50-99% is recycled.  Wash water is used in amounts of 5-100% wt. of the hydrocarbon.  Temperatures in the settling tanks may be 80 DEG -200 DEG  F.  The distillation tower is maintained at 200 DEG -350 DEG  F. and 1-50 p.s.i.g. using 10-25 bubble cap plates.

Title: Improved calculator
Inventor: OWEN CHARLES EDWARD
IPC: G06F3/08
Filed: 1964-08-11
Abstract: 1,085,528. Electric digital calculators. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 17, 1965 [Aug. 11, 1964], No. 32643/64. Heading G4A. In a calculator, corresponding-order digits of two operands are added in a full-adder, the result being modified or not in accordance with its value and the radix used and then fed back to the adder input via a delay line which together with the adder and modifier forms a calculation loop holding in series the digits of the operands and result. Fig. 2 shows a circuit for multiplying two binary-coded decimal operands A, B, applied serially by bit, to get a result C, by halving and doubling. The sum output of the adder 1 is passed to first and second four-bit shift registers 3, 4 to the latter 4 via a second fulladder 2 which adds the filler digit 6. Halving is done by shifting from the penultimate stage of the first register 3 to get three bits and taking the fourth bit from the carry output of the first adder 1. If the ignored bit in the first register 3 is 1, ten is added into the first adder 1. Doubling is done by applying the digit to both inputs of the first adder 1, the result being passed to the (magnetostrictive) delay line 13 from the first or second register 3, 4 depending on whether the first adder 1 produced a carry. The decimal digit distribution of the operands A, B and result C in the calculation loop is as follows: . . . CBCBCBAAA . . . A (early end) most significant A digit and least significant B and C digits first. A slight modification to perform sequential multiplication A x B = C, C x D = E, &c. is described briefly. Fig. 5 (not shown) shows means for inserting digits from punched cards into the appropriate positions of the calculation loop and printing out digits from the loop. A counter scans a matrix in synchronism with the loop circulation, the matrix gating pulses from the card reader into the loop at the appropriate times for read in, and actuating print drivers when the appropriate digits in the loop agree with digit identifying signals from the card mechanism for print out. Fig. 6 (not shown) shows an embodiment for performing calculations of the form on serial-by-bit signed binary-coded-decimal operands by halving and doubling and successive subtraction and addition. A delay line, with a digit distribution as follows: DB . . . DBDBACAC . . . AC (early end) least significant digits first, feeds a series combination of a first four bit shift register, a first adder/subtracter, a second register and a second adder/subtracter, the latter feeding the delay line. Provision is made for carry to/ borrow from the next decimal digit, and for addition of filler digit when there is a carry from the first adder or when a carry would be generated from the 8-bit of the first adder output by addition of the filler.

Abstract: 409,795. Safety razors. GILLETTE SAFETY RAZOR CO., 15, West lst Street, Boston, U.S.A. Nov. 18, 1932, No. 32668. Convention date, May 7. [Class 30.] In a safety razor having folding blade-clamping sections 15, pivoted about their longitudinal edges 16 to a blade-support 10, as described in Specification 400,621, quick-acting means are provided for folding the sections over the blade 35 followed up by slowacting means to clamp and flex the blade. The quick-acting means comprise arms 27, on a rotatable handle-sleeve 24, engaging helical cam-slots 17 in the edges 16 of the clamping sections. The slow-acting clamping-means comprise a headed stem 30 riveted to an endknob 25 which has a frictional fit on the enlarged end 22 of an intermediate sleeve 21, fixed to the blade-supporting plate 10, and forming a bearing for the rotatable handle sleeve 24. The member 22 is split so as to be resilient and carries a screw-pin 23 engaging a cam slot 26 in the knob 25. By holding the handle 24 in one hand and rotating the knob 25 with the other, the razor head is rotated about the handle, through the frictional connection between members 22 and 25, to fold the clamping-sections 15 rapidly over the blade. The increased resistance then encountered causes the knob 25 to slip over the member 22 whereupon the pin-and-slot connection 23, 26 acts to retract the stem 30 and clamp the blade. The edges 16 of the clamping-sections 15 are spaced by a slot 19 from the remainder, to allow the blade-edges to protrude, and are grooved on their upper surface to provide guard teeth. The stem has a guide-collar 32, and, in a modification, a screw-thread between this collar and the sleeve 21 replaces the pin-andslot connection 23, 26. The blade is located on the plate 10 by diamond-shaped pegs 12 and it is flexed by the outer edges of the clamping- sections over the fulcrum edges of the flat supporting-plate with a power-multiplying lever action.
