Title: Improvements in or relating to the distillation and cracking of tars, oils and like liquid hydrocarbons, and of fats
IPC: C10C1/04
Filed: 1936-02-24
Abstract: <PICT:0472541/III/1> Tars and other hydrocarbons and fats are dehydrated and distilled, with or without cracking, by first depriving the preheated starting material of part or all of its more volatile constituents by mixing it with hot already treated heavy non-volatile residue and then causing the mixture to circulate, at a speed independent of the through-put of the plant, through a single coil still whereby further volatile constituents are evolved, the constituents evolved at both stages being fractionated without intermediate condensation and the whole process being carried out in one operation and in a single plant.  Tar from a tank A is preheated in a heat-exchanger B and passed by pipe I to a thermostatically controlled valve K admitting it into a mixer column D in admixture with hot previously treated material escaping from a vapour box G by a pipe H.  The material collecting in the base of the mixer column is circulated by a pump E through a pipe still F into the vapour box G, from which it passes into the mixer column D by lower and upper entry pipes J and H respectively.  The thermostatic valve K is so adjusted that, when the plant is in steady operation, no tar is admitted unless the temperature of the treated material flowing through the pipe H is sufficiently high to ensure that all volatile constituents have been expelled.  When this is so, and a sufficient depth of material has accumulated in the base of the mixer column, finished pitch can be drawn off steadily through a valve L.  The volatile constituents passing off through pipes Z and M are fractionated in a column C, the lightest fractions being condensed in the heat-exchanger B and recycled in part to control the temperature of the top of the column by means of a thermostat N.  Condensates are taken off at suitable points T, U and so on.  A steam coil W and inlets V<1>, V and X for free steam may be used to assist the process.  The pitch leaving at L can be subsequently air-blown to harden it, or hot air may be introduced into the pitch at the top or bottom of column D.  By introducing bitumen, rosin &c. into the mixer column, products are obtained which can be emulsified directly with water in a high-speed mill.  The plant is particularly suited also for the revivification of wash oils. When cracking is desired, the pipe still or the mixer column and pipe still together, are placed under appropriate pressure by the application of check valves at the outlet, the pressure being released before the vapours reach the fractionating column. Catalysts may be placed in the mixer column. Specifications 307,577, 337,581, [both in Class 32], and 424,645 are referred to.

Corsets; gaiters.-In separable fasteners of the type wherein two flexible stringers are locked and unlocked by a sliding camdevice, the channels of the slider diverge at a small angle so that the fastener can be used for straight or curved edges, positive operation of the slider being necessary in each direction; the slider is provided with means for locking the fastener in the closed position; and the stringers are extended beyond the edges of the garment &c. to enable a wider opening to be obtained. The stringers 3 comprise tapes having corded edges 4 to which are clamped interlocking members 5 provided on opposite faces with rounded heads 44 and sockets 44'. The channels 10 of the slider are practically straight and diverge at a small angle, and the inner ends 42, Fig. 12, of the members 5 and the inturned edges 43 of the slider are shaped similarly to prevent distortion under heavy strain. The slider is moved in either direction by a plate 22 pivoted in a loop 23, this plate serving also as the locking means, being provided with spring arms 24, which, when the plate is turned down into the position shown in Fig. 1, engage with the ends of the slider channels and obstruct the passage of stop members attached to the stringers. Fig. 5 shows a slider without locking means suitable for closures requiring to be operated from either side; a loop 31 is attached to each side of the slider, and each loop carries a pull-ring 32. The extensions 11, Fig. 1, of the stringers may be provided with interlocking members 5, and are secured together by a stop member 12. By slitting one end of the securing strap 16 of a spat 15, Fig. 16, and securing the stringer extensions to the two parts, the spat can be opened sufficiently, by moving the slider to the lower end of the extensions, to permit removal of the spat without undoing the strap. The body 20 of a corset, Fig. 15, is provided with flexible extensions 21 to which the stringers are secured, so that the corset can be opened sufficiently to enable the wearer to step out.

Abstract: 1460412 Measuring blood pressure AMBITEX CORP and CENDEV CORP [trading as AMBITEX CO] 12 Feb 1975 [28 Feb 1974] 5933/75 Heading G1N (E) In a blood pressure measuring device such as that disclosed in Specification 1460413, gas from a reservoir 10 is pumped by a pump 14 into an inflatable cuff 13, the air being allowed (during measurement) to pass back via a valve 17 to the reservoir 10. The valve 17 is controlled by a feedback loop so that the rate of pressure decrease in the cuff is constant. The output from a pressure transducer 18 is supplied to a pressure display 23 and to a differentiating circuit 20 whose output is fed to a differential amplifier 21 which also receives a reference voltage. The differential amplifier 21's output is then used to control the valve 17 so that the reference voltage and the differentiating circuit outputs are equal and thereby maintaining the rate of the pressure decrease constant. The pump 14 is energized by depressing a switch SW1 which connects it to a power supply 16 that also operates a closure means 24 so that the valve 17 is closed when the pump is actuated to build up the pressure in the cuff 13. A stethoscope 24 is shown but the description indicates that automatic processing using an acoustic transducer is possible (see copending Application).
