Abstract: <PICT:0730375/III/1> A heat exchanger comprises a casing through which a heating or cooling medium is caused to flow, the casing surrounding a tube assembly comprising superposed sections or bundles of fluid-tight graphite tubes through which flows a liquid to be heated or cooled or a liquid and a gas undergoing heat exchange and/or interaction one with the other, the liquid and/or gas having corrosive properties each tube bundle having at its upper end a horizontal floor (e.g. 4 or 5) with the tube ends projecting above the floor the individual tubes being closed at their upper ends (e.g. by closures 6) and having lateral slot-shaped openings 7 into which liquid can flow from the horizontal floor, the openings 7 being so disposed as to enable the inner walls of the tubes to be wetted uniformly by the liquid in the form of a thin film.  In the apparatus shown for the manufacture of hydrochloric acid, hydrochloric acid gas enters through a port 8 and flows upwardly through the tubes in direct contact with and in counter-current to water flowing downwardly through the tubes from an inlet 3.  The flow of gas and liquid may however be co-current.  Filling members e.g. Raschig rings or rods provided with ball-shaped enlargements (Fig. 4, not shown) may be provided in the last section or last two sections through which the gas passes before leaving the apparatus.  The spacing and/or cross-sectional area of the tubes may vary in different sections of the column.  The casing is composed of sections (e.g. 1 and 2) corresponding with the tube groups, cooling water flowing through each section from an inlet 9 to an outlet 10.  An inlet and an outlet may however be provided at both ends of a casing section. It is stated that the apparatus may be used for other processes in which a gas and liquid interact with evolution or absorption of heat. When used for heating liquids which react with gases, steam or hot liquid is passed through the casing sections.

Title: Braking systems
IPC: B60T8/74
Filed: 1971-05-05
Abstract: 1326347 Fluid pressure brakes; warning devices H GFELLER 5 May 1971 [12 May 1970 22 April 1971] 13181/71 Headings F2E and F2F A brake pressure regulator 13 for a spring applied fluid pressure applied released actuator 7 on a rail vehicle comprises a flywheel 19 which in normal braking rotates with a spindle 17 connected through gearing 16 to a wheel 14 but when the deceleration exceeds a predetermined value the flywheel 19 overruns the spindle 17 closing off the normal fluid pressure exhaust from the pressure chamber of the actuator through an inlet 29, passages 24, 25 in the spindle, and passages 27 in a valve body 26. The overrun of the flywheel is limited by a spiral spring 21 fixed at its end to flywheel 19 by a threaded pin 22, and to a disc 23 secured against rotation relative to the spindle. In the brake system shown oil is pumped to the inlet 7D of a hollow piston-rod 7A of brake cylinder 7 from a pump 1 through check valves 2, 5 provided in a conduit 1A, a brake valve member 6 normally being held closed by pressure in a branch line 1B. In the embodiment shown the brake cylinder is spring applied, fluid pressure released and to apply the brake a valve 8 is actuated, manually, by an emergency brake handle or automatically by the snapping of a cable in aerial cable vehicle system allowing pressure to be relieved on one side of valve member 6 and part of the oil to pass from cylinder outlet 7 to an accummulator 9 the oil pressure in which is opposed by a gas pressure which thereby determines the initial braking power, and the remainder of the oil to pass through regulator 13. At a predetermined deceleration the flywheel over-runs to prevent further escape of fluid through the regulator. In a further embodiment overrun of the flywheel causes axial movement of a valve piston 125, Fig. 6 (not shown), thereby cutting off communication between radial inlet and outlet ports (127, (128) in valve body (126), axial movement of the piston (125) taking place through pins (131) arranged to radially engage through a slot (132) in the spindle with a peripheral groove (135) in the piston (125). Axial movement of piston (125) operates a switch (140) to indicate whether the spring is broken. A magnetic device (144) may be used comprising magnets (143) fitted into one end face of the flywheel which moves past a magnetic switch (144) fitted in the regulator casing (118) as the flywheel rotates to give a check on the rotation thereof. The actuator 7 may be fluid pressure applied.

Abstract: 755,045. Cupola furnaces. STRIKFELDT, W. S. May 7, 1954 [May 23, 1953; Aug. 3, 1953 ; Jan. 7, 1954], No. 13395/54. Class 51(2). Wall temperatures in the melting zone of a cupola are regulated by forced circulation of water through cooling elements in the region of the melting zone, and maintaining the working pressure of the water at a constant level corresponding to the desired temperature of the water evaporated in the cooling elements. In the embodiment shown in Figs. 1 and 3, the cooling elements 1, arranged vertically in groups of three near the inner face of the cupola wall, are fed with water by a pump 9 through a conduit 3; a distributing ring 4 and valvecontrolled branch pipes 5. Return flow is to a steam and water drum 8 having a steam off-take 11 controlled by a valve 12 to adjust the pressure in the system. The circulating space in the cooling elements is restricted by baffles 2 and studs 7 are provided to which refractory material is applied. The cooling elements may be of round, square or rectangular section arranged on the outside of the cupola wall, Figs. 4-6 (not shown), or may comprise sinuous pipes which are also disposed between the tuyeres, Fig. 7 (not shown). The cooling system may also be applied to other parts of the cupola, as for instance in Fig. 9 wherein cooling elements 27, 28, 29 and 30 are applied to parts of a receiver 24 arranged out of axial alignment with the shaft and having a slag notch 25 and a metal discharge spout 26.

Abstract: 234,641. Littlewood, J. June 4, 1924. Stop-gear operated when driver releases a wheel; relay or power apparatus.-The steering- hand-wheel is made in four sections one of which is connected to controlling gear so that if the driver releases the wheel this section moves and shuts off the power supply and releases a weight which trips a catch and allows springs to apply the brakes. The first section 1 is fixed to the steering-shaft 5, the second section 2 is fixed on a long sleeve 6 having a cam disc 11 adapted to operate the controlling gear, the third section 3 carriers spring-pressed pins 9 which are pressed by the boss of the fourth section 4 into corresponding holes in the boss of the second section, thus locking the second section against independent rotation. When the wheel is released the pins 9 are withdrawn from the second section, and an eccentric weight on this section causes it to rotate and thereby, through the cam disc 11, operate the ignition or power switch 13 and release a weignt 15 to apply the brakes. This weight is held by a catch 14, and when released drops on a platform 17 which releases a catch 18 and allows springs 20 to act on a slide 19 and operate the brake levers 21. Other power means may be used to apply the brakes instead of the springs 20. The second section when released may be caused to rotate by other means than an eccentric weight. According to the Provisional Specification, the steering hand-wheel comprises three sections.

Filed: 1950-05-31
Abstract: 672,463. Cigar-making machines. NAAMLOOZE VENNOOTSCHAP VEREENIGDE TABAKSINDUSTRIEEN MIGNOT & DE BLOCK. May 31, 1950 [June 14, 1949], No. 13647/50. Class 130. Automatic delivery of the correct amount of scrap filler tobacco to a press 23 is effected by a charge sizer in the form of a pinned roller 1 rotated intermittently by a ratchet wheel 4 on the roller shaft 3 and driven by a pawl 5 on an arm 7 reciprocated through a preferably adjustable angle as by a driving link 8, the pawl 5 being lifted out of the wheel 7 for a part of its active stroke corresponding to the amount of tobacco already in the press 23 by a cam 10 co-acting with the pawl as through a roller 11 thereon and turnably mounted on the shaft 3 so as to be adjustable according to this amount. Tobacco received by the press 23 from the roller 1 via a chute 22 is periodically compressed by a plunger 24 reciprocated from a driving member 28 through a compression spring 26 housed in the member and acting on the plunger rod 25, individual cigar filler plugs being periodically cut off from the compressed tobacco by a knife 38. At the end of every compression stroke of the member 28 an abutment 36 thereon disengages a spring-engaged pawl 19 from a ratchet wheel 17 operatively connected to the cam 10 by a linkage 15, 13, 12, and allows a spring 18 to bring the cam 10 fully into the path of the pawl 5. During the following compression stroke of the member 28, another abutment 30 on an arm 31 pivoted to the member 28 co-acts with a slidable member 35 to rotate the wheel 17 through a link 16 thereon until, at a point depending on the amount of tobacco in the press 23, the resistance of the spring 26 is overcome sufficiently to bring a chamfer 32 on the arm 31 against a roller 33 on the rod 25 and lift the abutment 30 clear of the member 35. This leaves the cam 10 in a corresponding position relative to the pawl 5, which is then actuated before the member 28 reaches the end of its stroke.
Patent GB-378090-A (GB)
Title: Improvements relating to electric telegraph systems
IPC: H04L25/42
Filed: 1931-05-08
Abstract: 378,090. Code telegraphy. IMPERIAL & INTERNATIONAL COMMUNICATIONS, Ltd. and HIGGITT, H. V., Electra House, Finsbury Pavement, London. May 8, 1931, No. 13658. [Class 40 (iii).] Signals are stored in condensers which are charged and discharged by two independently driven distributers so as to produce a variable phase-lag, particularly in systems where two or more cables feed into a single multichannel cable or vice versa. Figs. 3 and 4 show a multichannel cable c fed by a high-speed cable a and a cable b working at half the speed of a, the cable code being employed. The relay system Xa Ya, Fig. 3, comprises a dot relay Xa, and dash relay Ya, Fig. 4. When a dash signal is received from cable a, armature xa applies a positive charge through brush Ax to one of the condensers K. Shortly afterwards this condenser is discharged through brush Fx and relay Xc, so that a positive or dot signal in the cable code is sent on to cable c. Similarly a negative or dash signal from cable a is effective to operate dash relay Ya, which through brush Ay applies a positive charge to a condenser K, a negative or dash impulse appearing in the cable c through brush Fy and relay Yc. In a similar manner the dot relay Xb and dash relay Yb pass on signals through the brushes Bx, By, condensers K and brushes Fx, Fy to the output relays Xc, Yc. The distributer ring Ga allotted to channel a has twice as many segments as ring Gb allotted to channel b, but the segments in each ring are evenly spaced. The output brushes Fx, Fy are driven by the same motor as one of the pairs of input brushes, such as Ax, Ay, which is synchronized with the signals in cable a. The remaining pair Bx, By, is synchronized with the signals in cable b, and small variable phase differences between the brushes do not impair the spacing of the outgoing signals. In the inverse arrangement, Figs. 5 and 6 (not shown), a multichannel cable feeds into two cables having different signal speeds. In another embodiment of the invention, Fig. 2 (not shown) and Fig. 1, the signals in the outgoing cable c are synchronized with those in one a of the incoming cables, while the signals in cable b, which are of equal speed with those in cable a, are variably retarded by a condenser-and-distributer system S. So long as the phase-difference between the a and b signals does not exceed a given limit, the signals are sent on to cable c in correct relation to one another. Should this limit be accidentally transgressed, resistances t prevent short-circuiting of the battery. The system may be adapted for Wheatstone morse signals, two brushes instead of two pairs of brushes being required in this case. Means for breaking up block signals may be provided. The invention may be applied to a triangle of three stations in which signals sent out by one station are repeated back to it through the other two.
