Title: Improvements in and relating to heating installations
Inventor: BARRAULT RENE LOUIS
IPC: F22B21/06
Filed: 1970-04-28
Abstract: 1,272,711. Water tube boilers. R. L. BARRAULT and R. E. J. WEBER. 28 April, 1970 [28 April, 1969], No. 20327/70. Heading F4A. A multitubular boiler is substantially symmetrical about an axis XY which is vertical as shown but may be up to 60 degrees from vertical. The top and bottom torroidal reservoirs 2, 1 are interconnected by three banks of vertical water tubes 3, 4, 5 which are bent at their ends to meet the reservoir surfaces perpendicularly. As indicated by arrows F1-F4 the hot gases from burner 8 pass down the centre of the boiler and are deflected around tubes 3, 4, 5 by a baffle 11 closing the reservoir 1 and annular baffles 6, 7 extending from the bottom reservoir 1 to near to the top reservoir 2 and vice versa. Finally the gases leave through bore 18 and flue 15. The water tubes may be replaced by annular water vessels having apertures for the hot gases to pass through. The boiler is enclosed by a removable insulation jacket 12 which may be surrounded by a water tank 16, 17 for preheating feedwater. Cleaning jets for steam or compressed air are provided in tubes 9, 10 for the removal of soot deposits. In hot water production cold feedwater rises through pipes 3, 4, 5 in parallel. In steam generation feedwater is introduced into the top reservoir 2 which is kept half full of water and after partly mixing with heated water descends through the cooler outer tubes 4 to reservoir 1 and returns through hotter tubes 3, 5 where steam is generated. In an alternative form for the production of both steam and hot water a third torroidal reservoir intercepts the tubes 3, 5 and thus rising hot water flows through it before entering upper reservoir 2. A further bank of tubes may be provided for superheating.

Title: Automatic cut-outs for dynamo-battery systems
Inventor: READ VICTOR JOHN
IPC: H02J7/22
Filed: 1956-07-02
Abstract: 803,599. Self-contained supply systems. C.A.V. Ltd. May 27, 1957 [July 2, 1956], No. 20373/56. Class 38 (4). Automatic cut-out apparatus of the kind used in dynamo-battery systems wherein a battery k is charged from a variable speed dynamo c, the field system h of the dynamo being controlled by an electromagneticallyoperated voltage regulator m, n comprises an electromagnet having a winding b responsive to the dynamo voltage for closing the cut-out contacts a, a dual switch having parts e, f which, when closed, short circuits, by means of the part e, a resistor g in the circuit of the dynamo field winding h and completes, by means of the part f, the circuit containing the winding b of the electromagnet, a second electromagnet being provided having normallyopposed current and voltage-responsive windings i, j respectively for opening the parts e, f of the dual switch when current flows from the battery k to the dynamo c. In operation, when the dynamo voltage reaches a predetermined value-at which value it is regulated by the voltage regulator m, n-the contacts a of the cut-out are closed, a series winding d being provided in the cut-out which supplements the action of the cut-out winding b. If the dynamo speed falls and the dynamo voltage drops below the battery voltage the current in the winding i reverses whereby the electromagnet operates to open switch parts e, f which deenergizes the cut-out winding b to open the contacts a promptly and to insert the resistor g in the circuit of the field winding h, thus causing a further sudden drop in the output voltage of the dynamo c to cause the electromagnet i, j to be de-energized sufficiently to allow the switch e, f to re-close and restore the initial conditions.

Title: Multiple effect evaporators
IPC: B01D1/26
Filed: 1971-04-19
Abstract: 1319553 Multiple-effect evaporators AEROJET-GENERAL CORP 19 April 1971 [10 Feb 1970] 20456/71 Heading B1B Multiple-effect evaporation of a liquor, e.g. brine, is carried out in a cylindrical housing 10 divided by barriers into effects 13..20 each containing a bundle 21, 22, 23 .. of vertical heat transfer tubes, the barriers being arranged so that the vapour flows perpendicular to the axis of the housing and in opposite directions in adjacent effects. Owing to the trapezoidal cross-section of the tube bundles, the vapour flow area decreases in the direction of vapour flow. Brine is introduced through conduit 30 to the interior of the tubes of bundle 21 of the first effect 13 and flows in film-form down the inner surface of the tubes. Steam is supplied through conduit 26 into chamber 27 of the first effect 13, and passes over the upper edge of wall 28 to condense on the outside surface of the tubes of bundle 21. A mixture of residual steam and non-condensible gas passes through apertures in wall 31, and is discharged through conduit 32. Steamcondensate is discharged through conduit 34. Some of the water evaporates from brine flowing down the tubes of bundle 21; and the vapour leaving the lower ends of the tubes flows, in a direction normal to the axis of the housing, into chamber 36 and the space surrunding the tubes of the next effect 14. Concentrated leaving the first effect through conduit 137 may be pumped to the tubes of the second effect via a chamber 29 where partial flash evaporation takes place due to pressure-decrease. The operation of the subsequent effects is similar to that already described, but the direction of vapour flow in each effect is opposite to that in the adjacent effect.

Title: Process and device for the manufacture of igniting cords
IPC: C06C5/08
Filed: 1934-07-13
Abstract: 420,285. Match-making machines. TIDEN, E. F., Reftele, Sweden. July 13, 1934, No. 20545. [Class 50] Igniting cords of twisted paper or fibre as of cotton or peat and successively impregnated with phosphoric acid and paraffin, are provided at intervals with ring-like friction igniting heads by applying the igniting material so that the applying member does not itself contact with the cord which is twisted at least one revolution whilst in contact with the material. Cord stock rollers 14 are pressed together on a shaft 15 by a spring, adjacent rollers being oppositely wound so that they brake each other as the cords unwind. The cords pass once round a crank-operated roller 18 to prevent slip and extend over an igniting material receptacle 1 between twisting appliances 22, 23, being secured at their ends to a truck 24 running on a horizontal track 26 and connected by a draw-line 28 to a weighted truck 30 on an incline 31. Another draw line 33 wound on a drum 34 serves to pull the truck 24 to the left by rotation of a crank 35. The twisting appliances each consist of two rails 37, 38, the upper ones being pressed by springs 38 against the cords and the lower ones being longitudinally displaceable on rollers as by means of a connecting handle. The receptacle 1 is placed in a heated water, &c., container 3 in which is disposed a frame 4 carrying applying plates 5 projecting through slots in the receptable 1. Frame-supporting rods 7 are raised by a pedal 12 to a point determined by contact of a ring 13 with packing brushes 8 in which position igniting material on the plates 5, but not the plates themselves contacts with the cords. The twisting appliances are then moved so as to rotate and drag the cords laterally through the material preferably once in both directions, the pedal then being released and the cords again rotated a few times to provide an even shape to the adhering material. After the bars 37 are raised by members (not shown), roller 18 is rotated once to provide another length of cord over the igniting receptacle.

Title: Improvements in or relating to telemetering systems
Inventor: WILSON, BERNARD T.
IPC: G06F17/40
Filed: 1963-05-23
Abstract: 1,051,132. Electric selective signalling. SHAND & JURS CO. May 23, 1963, No. 20646/63. Heading G4H. A central station in a telemetering system is normally in communication with alarm units via at least one field station, but the latter can change the communication to a control or data transducer when the transducer is selected by the central station. In the normal mode, a counter at the central station addresses the field stations in turn by sending for each a five-bit (binary) primary address followed by five ONES (to indicate that this is the normal mode)-sync. and end-ofcharacter bits are also provided. On recognizing its address, a field station returns the address to the central station for checking and scans two-state apparatus units connected to itself in turn (Fig. 10, not shown). Those units in a first state set corresponding flip-flops which cause associated permanent lash-ups of diodes to be scanned to provide the addresses of the units in 2-out-of-5-code, which are sent to the central station. The diodes associated with units not in the first state are skipped without delay. At the central station, if the returned primary address was valid and if the unit addresses are verified to have two ONE bits, lamps corresponding to the unit addresses are lit and punch-out occurs. Timing at central and field stations is started by sync. bits received each character time but if the expected signal from a field station does not arrive after a certain delay timing is restarted at the central station anyway. A control or data transducer can be selected by specifying its (binary) primary and secondary addresses, the former specifying the field station and the latter its location with respect to the field station. These addresses are transmitted, and returned for checking. If the check is good, a lamp corresponding to the address is lit at the central station, and data may be received from the field station or control signals transmitted thereto. If the selected transducer is a data transducer, data characters in 2-outof-5 coded form are sent from the field station, checked and displayed on character-shaped arrays of lights if correct. A character is also sent to indicate the type of data and all (correct) characters are punched out. A control or data mode cycle is followed by a normal cycle starting at the same field station, the address being forced into the addressing counter. End of message characters are used in transmissions, and when the central station receives one it retransmits it to all field stations. Application to the petroleum, chemical and electric power industries is envisaged.
