Title: Apparatus for stretching synthetic filaments
Inventor: BRANDI RICHARD A
IPC: D02J1/22
Filed: 1966-04-15
Abstract: 1,147,344. Filament stretching apparatus. HEPLON Inc. 15 April, 1966, No. 16636/66. Heading B5B. Apparatus for stretching a tow of synthetic filaments such as nylon a predetermined amount comprises a series of positively driven rolls for successive passage therearound by the tow and adapted for rotation at fixed peripheral speeds which increase in the direction of travel of the tow and a series of drag rolls each of which is freely rotatable and one or more of which is provided with means for individually locking it against rotation to impart additional stretch to the tow by controlled frictional drag. The drag rolls are so positioned that the tow travels in a sinuous path in contact with the peripheral surfaces of the drag rolls before it travels over the driven rolls. The drag rolls may be disposed between a creel support and the driven rolls. The latter may all be driven by a common constant speed motor. The tow after leaving the last of the series of driven rolls over which it has travelled in a sinuous path may pass through the nip of a pair of nip rolls driven at a peripheral speed higher than that of the last of the series of driven rolls. The nip rolls may be driven by the same motor as the series of driven rolls. One axle of each of the drag rolls may be provided with a longitudinally extending peripheral groove adapted to receive the end of a bolt threadably engaged with the bearing in which the axle is rotatably mounted. When the bolt is screwed into the bearing its end enters the groove and the drag roll is thereby locked to the frame of the stretching machine. When the bolt is unscrewed sufficiently far for its end to be withdrawn from the groove in the drag roll axle the roll is no longer locked to the frame and is freely rotatable. When all the drag rolls are thus unlocked, the tow is stretched by the driven rolls only. The extent of this stretch can be increased by locking one or more of the drag rolls when filaments of higher denier are to be stretched.

Title: Improvements in the heat radiation systems of oil insulated transformers
IPC: H01F27/12
Filed: 1928-06-08
Abstract: 316,378. Digby, W. P., and Fairthorne, R. B. June 8, 1928. Transformers. - In oil-immersed transformers in which the tank is provided with heat - dissipating surfaces such as tubes or corrugations, cooling is augmented by supplying an evaporative liquid to the hotter parts of the surfaces, excess liquid being led awav before it reaches parts where the temperature approaches that of the liquid. In one form, Figs. 2 and 6, fibrous material 2 is wrapped round the upper parts of the radiator tubes 1 of the oil tank and is kept moist by water supplied to the upper clamping collars 3, excess water being led away clear of the lower parts of the tubes either by drip wires or by pipes 5. The collars 3 are fcrmed with annular grooves 8 communicating with axial grooves 12 and with a channel 9 to which water is supplied through a drip cock 11 from supply pipe 10 encircling the upper parts of the tubes. A second section of wrapping may be placed below the first section of wrapping on the tubes, a fresh supply of water being introduced at the lower level. Where the tubes 1 communicate with headers, the wrappings may be arranged to project into a tray, to which water is supplied, at the upper ends of the tubes, a collecting tray being provided at the lower end. Where clamping collars are not employed, the fibrous material may be wrapped helically round the tube and secured in place by lacing or snap fasteners. Alternatively it may be in the form of woven sleeves placed in position on the tubes before they are built into the tank. Where the fibrous material is applied to the corrugated walls 18 of a tank, it may be secured in place by wooden wedges 21, Figs. 11 and 12, disposed between the corrugations. Means for indicating, and if desired regulating, the amount of moisture in the wrappings may be provided. These may comprise conducting collars 25, Fig. 13, spaced apart on the wrappings so that sections 26 of the wrappings may be connected either in series or in parallel and incorporated in a Wheatstone bridge circuit. Variations in resistance of the wrappings due to variations of moisture content may thus be caused to operate an indicator or a control device associated with the water supply. The collars should be of a material electropositive to that of the tubes. In an alternative arrangement, collars of dissimilar metals are provided on the wrappings so that galvanic cells are formed. These are connected in two series groups normally balancing each other end associated with a differential relay so that in the event of unbalance arising due to deficiency of moisture in certain tubes an indication or correction is made. Condensation of moisture on the terminals of the transformer from the rising air above the tubes 1 is prevented by the provision of ducts through which the air rises by natural draught or by forced draught controlled by load variations.

Title: Method of and apparatus for humidifying air
IPC: F24F3/14
Filed: 1924-07-11
Abstract: 219,021. British Arca Regulators, Ltd., (Aktiebolaget Area Regulatorer). July 11, 1924. Air, moistening.-In a process for humidifying air for use in workrooms, the amount of water admitted to sprayers is automatically controlled in relation to the degree of humidity of the air, by allowing the water to flow through an additional aperture the size of which is controlled by humidity sensitive means. The spraying devices comprises a disc b rotated by an electromotor a, water being supplied from a pipe d through a hollow shaft c. The motor current is supplied through wires e, f, and is shut on and off from a switch g. The water flows from a pipe k, and its pressure on a diaphragm n, controlling the spring p on the switch g, causes the current to be turned on, and the disc b to be rotated, before the water reaches the top of the pipe d. The amount of water supplied to the disc is controlled by the quantity of water allowed to escape through the opening m, partly closed by a spring- controlled member s. The distance of the latter from the opening m is regulated by threads t, the length of which alter with change of humidity of the surrounding air.

Title: Variable flow metering devices
Inventor: CURRAN JOHN PATRICK STEWART
IPC: F02K3/00
Filed: 1965-04-22
Abstract: 1,122,263. Valves. JOSEPH LUCAS (INDUSTRIES) Ltd. 14 July, 1966 [22 April, 1965], No. 16934/65. Heading F2V. [Also in Division F1] The invention relates to a variable flow fluid metering device such as used in gas turbine engine fuel systems. In the fuel metering device shown, a pair of axially spaced fixed sleeves 12, 13 are provided and an axially and rotatably movable tubular member 10 is disposed within the fixed sleeves. A movable sleeve 11 is mounted on the inner tubular member 10 between the fixed sleeves 12, 13 and defines therewith two axially-variable annular fuel metering orifices. The inner tubular member 10 is formed with two metering orifices 10a, 10b of triangular form, the base of the triangular orifice 10a being smaller than that of the orifice 10b. The triangular orifices 10a, 10b co-operate with the annular orifices between the sleeves 11, 12, 13 to form fuel metering orifices of variable area through which fuel flows into the space within the inner tubular member 10. The adjacent ends of the sleeves 12, 11 and 13 are chamfered such that the radial depth of the ends of the sleeves 11, 13 adjacent the triangular orifice 106 having the greater base length is less than the radial depth of the ends of the sleeves 12, 11 adjacent the triangular orifice 10a having the lesser base length. The arrangement is such that when the spaces between the movable sleeve and the respective fixed sleeves are equal, the relationship between the exposed areas of the openings and the radial depth of the sleeve ends tends to create a balance of the forces acting axially upon the movable sleeve at opposite ends thereof.

Title: Reaction propulsion engine and method of operation
IPC: F02C7/224
Filed: 1973-04-10
Abstract: 1392675 Ram jet propulsion units TEXACO DEVELOPMENT CORP 10 April 1973 17054/73 Heading F1J The invention relates to an air breathing reaction propulsion system in which a portion of the heat energy of the ram air is transferred to the fuel by indirect heat exchange between the ram air and the fuel, a portion at least of the heat transferred to the fuel being converted to useful work by direct expansion of at least a portion of the fuel. In Fig.1 the engine comprises a combustion chamber 10 to which ram air is supplied at 22, fuel from a container 14 being passed through a heat  exchanger 16 whereby the fuel is pre-heated. The pre-heated fuel discharges directly into the combustion chamber through an expansion nozzle 18 whereby the pressure of the ram air is increased by the injector action of the fuel expanding through the nozzle 18. The combustion gases discharge through a propulsion nozzle 12. In Fig.2 (not shown) only a portion of the pre-heated fuel is passed to an expansion nozzle (45) similar to nozzle 18 of Fig.1; the remaining portion of fuel passes to an expansion nozzle (50) where it is expanded directly to atmosphere. In Fig.3 the preheated fuel is passed through line 66 to a turbine 68 which drives an air compressor 70 in which the cooled ram air is further compressed and discharged through line 74 to the combustion chamber 72. The expanded fuel discharging from the turbine also passes into the combustion chamber, the resulting gases discharging through nozzle 78. In a similar system Fig.4 (not shown) part only of the pre-heated fuel passes to a turbine (88) driving the compressor (90), the remaining part of the fuel passing directly to the combustion chamber (98). The expanded fuel discharging from the turbine through line (92) discharges through an expansion nozzle (96) directly to atmosphere. In Fig.5 fuel pre-heated in the heat exchanger 124 disposed in the ram air intake duct 112 passes through line 134 to an annular combustion chamber 132 to which an oxidizer is passed through line 130, the resulting combustion gases being directed on to the turbine 140 which drives the compressor 142 in which the ram air is further compressed. The air from the compressor passes into the combustion chamber 144 together with the fuel-rich gases discharging from the turbine 140, the resulting gases discharging through propulsion nozzle 148. The engine is suitable for operation from static launch to velocities of Mach 10-12 at altitudes of 150,000 to 200,000 feet using hydrogen as fuel and, up to about Mach 3, liquid oxygen as the auxiliary oxidizer. Above Mach 3 auxiliary combustion in the chamber 132 is not required, so the supply of oxidizer through line 130 is shut-off, the fuel expanding directly through the turbine.
