Title: Improvements in hot water feeding for boilers
IPC: F22D1/42
Filed: 1926-05-12
Abstract: 252,700. Auxiliaire des Chemins de Fer et de l'Industrie. May 29, 1925, [Convention date]. Feedwater, supplying and 'controlling; hotwater storage apparatus. - Feedwater heating, means using waste heat in a locomotive or other boiler plant provides a reserve supply of hot water which is exclusively utilized in feeding the boiler when the engine regulator is closed, communication between the cold water supply and the feedwater injecting means being cut off. When the regulator is open the reserve supply is formed; feed may simultaneously be supplied under these conditions since the output of the water-heating means is greater than the maximum output of the injecting means, so that excess is delivered to the hot-water tank. In a plant comprising a feedwater heater A of the type described in Specification 220,208, a hot-water tank B, open to the atmosphere through a pipe 13, hot and cold water pumps 6, 7, and valves C, D, when the regulator is open steam from the engine valve-box enters the respective valve chambers 19, 36, to maintain the valves in the position shown so that pump 7 withdraws water from the tender through a suction vessel E and pipes 44, 45, and delivers it to the heater A through pipe 11. A part descends the pipe 5 to the pump 6 and is then discharged through valve chamber 20 and pipe 15 to the hot-water tank B by reason of the boiler pressure at the inlet 33. The heater receives exhaust steam from the pump engine, and condensed steam from the valve chambers is also delivered to the heater through pipes 12, 12a. Should it be necessary to supply water with the regulator still open, a cock 35 is turned so as to cut off steam from chamber 19, thus causing the valve 22 to descend and cut off the hot-water tank. At the same time an opening past a valve 23, through which steam is passed to operate the pumps, is increased. Pump 7, of larger volume than pump 6, continues to supply the feedwater boiler from the tender, and the excess over that delivered into the boiler enters the hot-water tank through a pipe 4. When the tank is filled water circulates through a pipe 14 into the suction chamber E, rising to the level of the inlet of a pipe 9, is discharged into a drip pan 10 observable by the driver, who then closes a cock 30 to stop the pumps. When the regulator is closed, valves C, D descend and pump 7 is placed in communication with the hot-water tank B through pipes 16, 45, the cold-water supply being cut off by piston 39 of the valve D.

Title: A process for the calorific improvement of charcoal and other porous fuels
IPC: C10L9/06
Filed: 1930-04-23
Abstract: <PICT:0353929/III/1> The calorific value of charcoal or other porous fuels, such as brown coal, peat or coke, is increased by subjecting it in a dehydrated condition to a stream of dry air at a temperature of 70-73 DEG  C. and under a pressure of 4-6 kilogrammes per square centimetre for several hours; the hot air may be alternated with cool air at 5-10 DEG  C.  The dried charcoal &c., preheated to 70-73 DEG C., is contained in an iron cylinder 1 and supported by perforated trays 10.  Dry air heated to 70-73 DEG  C. is supplied to the cylinder 1 by pipes 4, 5 from a reservoir 12, a second reservoir 13 being furnished from which the cooler air is supplied alternately with the heated air.  Air escapes through pipes 8 perforated at 6 and provided with safety valves 9.  The gaseous flow is so controlled that a volume of air, measured at 760 millimetres and 0 DEG  C., equal to 150-200 times the volume of the cylinder passes per minute. After 5-6 hours the inlet and outlet valves are closed and the cylinder allowed to cool under pressure, the charcoal being stated to absorb 280 times its volume of oxygen.  After removal from the container, the charcoal is provided with a protective coating by immersion in organic materials such as paraffin, petroleum, glue, rubber, gelatine, oils, &c., or in alkalies.  In a modification, easily inflammable substances, such as gasolene, are sprayed from a container 14 by pipes 15 into the current of air which, in this case, is circulated in a closed circuit.

IPC: H02K19/36
Filed: 1962-04-02
Abstract: 1,031,720. Synchronous dynamo-electric machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 1, 1963 [April 2, 1962], No. 12590/62. Heading H2A. In a synchronous dynamo-electric machine, e.g. motor having in shunt with its field winding 1 an impedance path 5 and two mutually oppositely poled shunt connected rectifiers 6, 7 at least one of which is semi-conductor controlled, the trigger electrode of the latter is so electrically connected to the impedance path that the rectifier is rendered conductive during alternate half-cycles if an alternating e.m.f. exceeding a predetermined value is induced in the field winding; thus, during the starting period of the motor, the e.m.f. induced by the 3-ph. armature stator winding 3 in the field winding 1 is dissipated in the shunt circuits, but as the motor approaches synchronism the rectifier becomes non-conductive to minimize power loss during normal running. As shown, both rectifiers are semi-conductor controlled and are serially connected with a resistor 8, and the impedance path is formed by a highresistance tapped resistor, but alternatively the rectifiers may be shunted directly across the winding, the latter being D.C. supplied via slip rings. In another embodiment a brushless motor field winding is supplied by a rotating exciter winding via rectifying means which also provide one of the two shunting rectifiers. The trigger electrode may be protected by a Zener diode circuit, and the circuit in Specification 954,604 may be used to withhold excitation until synchronism is approached.

[Class 108 (ii).] Comprises spring suspension in which each wheel of each pair of wheels is mounted on an arm 7 .. 10 pivoted about a transverse axis 3 .. 6 and each pair of which is connected to the ends of a transverse spring 11 or 12, these springs being fixed on a common longitudinal shaft 13 free to rotate in frame bearings 14, 15. The arms 7, 8 of the front wheels are pivoted at their centres to the frame 1, the wheel axles being at one end and the spring 11 at the other end, while the arms 9, 10 of the rear wheels are pivoted at one end to the frame and are connected at their other ends to the wheel axle and the spring 12. Any tendency of the vehicle to tilt laterally is resisted since tilting would cause the two springs to rotate in opposite directions. It is stated that if a front wheel passes over an obstacle there is a lifting tendency also at the rear of the vehicle, and that the accelerations imparted to the suspended parts are about one-fourth of what they would be with independent springs.

Title: Improvements in methods and devices for creping webs of paper and other sheet material
IPC: B31F1/18
Filed: 1936-05-05
Abstract: 466,733. CrÛping paper &c. ZELLSTOFFABRIK WALDHOF, and HAAS, R. May 5, 1936, Nos. 12712 and 12713. Convention dates, May 6, 1935 and Sept. 6, 1935. [Class 141] [Also in Group XVI] A process for the longitudinal crÛping of webs c of paper, metal foil or other sheet material comprises passing the web around part of the periphery of a curved roller a, Fig. 1, or of a body shaped at such part like a curved roller, and exerting pressure against the web where it passes around the roller. The pressure device which may consist of a block h, Fig. 3, or of an endless band or endless cords, causes the web to follow the narrowing surface of the roller and thus become crÛped longitudinally. The roller a may be. formed by bending a solid rubber tube or inflated rubber tube or may consist of a rubber tube drawn over a series of discs assembled on a curved axis b. Various methods are described for preventing circumferential deformation of the surface of the roller which is liable to tear the material. In one arrangement Fig. 9, projections t on internal discs u engage slots on the inner surface of the rubber covering s or pins on the discs may engage holes in the covering. Further, wires or fabrics may be inserted in the covering to prevent the deformation. Another method which may be employed is to make the covering of a number of rings secured to discs or of a number of longitudinal strips fitting in grooves in the discs, and the separate rings or strips may be arranged to overlap to prevent the material being nipped between the parts. The covering may be formed by winding on the members u a fabric which is yieldable only in the direction of its width. The outer surface of the covering S may be slotted as shown at E, Fig. 9. Either the roller a or the cords or band co-operating with it may be driven, and where driven cords are employed, the roller may be replaced by a stationary member shaped like a roller but with its upper segment removed. The web of material may be crÛped transversely before being submitted to the longitudinal crÛping, and the apparatus may be included in a machine for calendering or cutting the web. Also, a number of crÛping elements may operate on the web in succession.

[Also in Divisions B6, B8 and F2]  In a sheet forming apparatus of the type in which a continuous sheet is intermittently fed by pairs of edge engaging belts through heating and forming stations, the formed articles are separated from the rest of the sheet at a blanking station located beyond the belts. The distance between the forming and blanking stations is such that the sheet cools to a sufficient extent to avoid warping during the blanking and successive articles are separated by transverse channels which channels provide narrow zones in which deformation can occur during the movement of the sheet from the forming to the blanking station. In the described embodiment, a sheet 32 drawn from a roll supported upon a moving belt 40 is first heated at station 33 and then formed into pairs of side-by-side egg cartons between cooled matched moulds at station 34. The heater side of each mould is provided with a cooled heat shield, the edges of the shields co-operating during each mould closure to form a transverse distortable channel which separates successive pairs of cartons. The cartons are then forwarded under a printer 36 and move from chains 45 and 46 along guides to clamping and blanking stations 37, 38. At these stations one pair of articles is clamped and perforated whilst the preceding pair perforated in the preceding operation is stripped from the sheet by suitable shaped co-operable cutting dies.  The perforation is effected by the apparatus shown in Fig. 15. The cover portion of each pair of containers is gripped between members 155 and 162 and is perforated by an hydraulically actuated punch 167 passing through cooperating sleeved holes 164 located in the members.
