Patent GB-807546-A (GB)
Title: Flow mass meter
IPC: G01F1/80
Filed: 1955-04-18
Abstract: 807,546. Electric indicating systems. ROCKWELL MANUFACTURING CO. April 18, 1955 [May 4, 1954], No. 11064/55. Class 40 (1). [Also in Group XXIX] The energy used to impart a predetermined angular velocity to fluid passing through a meter, or the angular momentum acquired, is used to determine the mass flow rate. Fig. 1 shows an " energy-type " meter ; two rotating blade assemblies 75, 175 are driven independently at the same constant speed by electric motors, the radial vanes 74 of assemblies 75 ensuring that all fluid entering at 154, after passing through straightening vanes 56, is given the desired angular velocity. The energy taken by assembly 175 is subtracted from that taken by 75, in order to compensate for " secondary losses " of the motor, the nett energy used being measured by a watt or watthour meter indicating the mass flow rate or total mass passed through the meter. Fig. 3 shows a " momentum-type " meter ; the fluid entering at 254 is given a predetermined angular velocity by the vanes 274 of constant speed rotor 278, and then strikes radial blades 279 mounted on a rotatable hub 277, which reduce this angular velocity to zero, since the hub is restrained against rotation as indicated in Fig. 5. Ribs 284 on the fixed shaft 268 form polepieces coacting with polepieces 286 on hub 277; the couple on the hub is measured by a watt meter 257 which effectively multiplies the currents in the windings on the rotor 277 and stator 268. The current in the stator winding is controlled by a carbon pile 294 under control of magnets 296 and 295, so that only a small movement of the hub 277 is necessary to effect the force balance. In a modification, the radial blades imparting the angular velocity themselves constitute the armature of a constant speed synchronous motor. Specification 717,897 and U.S.A. Specification 2,602,330 are referred to.

Abstract: 599,068. Ground trainers for pilots. SPERRY GYROSCOPE CO., Inc. Aug. 10. 1942, No. 11200. Convention date, July 15, 1941. [Class 4] [Also in Group XX] The device described in Specification 849,331 is modified so that it may be used both for pilot trainers and on actual aircraft to indicate and record the simulated and actual ground speeds and directions permitting any change of wind conditions to be manually set and also to indicate and record the simulated or actual guide path during landing. The triangulation device shown in Fig. 1 is similar to that described in the aforesaid Specification except for the addition of a gear 11 mounted on the wind direction table 25 which gear operates, through a gear 13, a differential transmitter 15 which compensates for wind direction, the output of the transmitter 35 transmitting to a remote point the -simulated or actual ground speed according as the device is used on a trainer or actual aircraft, the wind speed being manually set on the device by the screw 29. The transmitter 15 has two polyphase-type windings, the transmitter 35 being connected directly to one of these windings while the output of the other winding is connected to a repeater motor which orients the wheel of the crab, the speed of the crab-wheels being controlled by a control circuit including a variable-frequency oscillator which may be similar to that described in the Specification. The true ground speed may be indicated by a scale and pointer 44, 46 or by a calibrated frequency meter included in the control circuit operating the speed of the crabwheels. When the device is used as a course indicator for actual aircraft, the shaft 17 is operated from a compass &c. so that the device responds to changes in the aircraft heading and the airspeed screw 21 is operated in accordance with the air speed indications by well-known means, while the wind speed and direction may be adjusted by the pilot in accordance with radio weather reports. Fig. 2 shows the recording equipment for aircraft landing, the upper part showing an elevation and the lower part a plan of the landing path and field. The crab 103 is slidable on a guide rod 107 movable on tracks 111. The recording pen 113 is moved by drive screw 117 which is actuated remotely by the altimeter. The chart 101 has indicated thereon or indicates the radio range 131, localizer beacon 133, marker beacons 135, 137, glide path 139, radio transmitter location 141, runways 143, field obstacles 144 and the recorded landing trace 145.

Patent GB-206171-A (GB)
Title: Improved method of and apparatus for generating the teeth of toothed gears
IPC: B23F5/14
Filed: 1922-04-21
Abstract: 206,171. Lewis, F. M. April 21, 1922. Gear-cutting; tools.-The teeth of straight or helical spur or bevel gears are generated by a process in which the blank is rotated when the generating movement between the cutter and the blank is substantially radial instead of as usual tangential to the blank. By this method indexing of the blank is eliminated. The blank a, Fig. 1, is carried on a spindle which is mounted on a slide k and which carries a worm wheel g driven through gearing from a wheel c on a shaft provided with a cam h co-operating with a fixed roller i. The radial feed and rotation of the blank are simultaneously operated by means of a ratchet rack n reciprocated by a pneumatic cylinder l driven from the power shaft which drives the reciprocating cutter b. The latter, which may be of substantially rack form, is positioned so that the gap between two cutting teeth is disposed radially of the blank, the cam h being so arranged that a complete radial generating reciprocation takes place while the blank rotates through one pitch. Alternative constructions for the cam wheel and ratchet drive are described and the generating reciprocatory movements may be imparted to the cutter instead of to the blank. For cutting bevel wheels the blank a<1>, Fig. 5, and cam wheel h<1> are mounted on a plate k<1> which is pivoted at a point k<2> approximately coinciding with the blank cone apex. In the application of the invention to helical gears either spur or bevel, a differential mechanism may connect the crossfeed of the blank and its rotation. According to the Provisional Specification the generated teeth are of involute form.

Title: Improvements in or relating to methods for operating a forced-flow once through boiler plant at low load
IPC: F01K7/40
Filed: 1956-04-13
Abstract: 801,019. Forced-flow steam boilers. SIEMENS-SCHUCKERTWERKE A.G. April 13, 1956 [April 16, 1955], No. 11310/56. Class 123(2) Flow instability in the tube system of the evaporating section 1 of a forcedflow, once-through boiler when operating at low load is avoided by passing a quantity of water which is several times greater ' than the steam output of the unit through the evaporating section thereof and recovering heat from the excess flow by preheating the feed water, the latter being drawn from a well 6 by a pump 5 which delivers it through heat exchangers 4, 3 into the section 1. The evaporating section is heated at such a rate as to produce wet' steam at a pressure not much in excess of the feed water pressure in the heater 3, the wet steam passing into a through-flow separator 10 e.g. a cyclone in which steam separates and flows through a superheater 2 to the H.P. stage 7 of a turbine, a reheater 9 being provided between that stage and the L.P. stage 8. Water from the separator flows serially through pressure relief devices 11, 12 in which its pressure is reduced in two stages, the steam liberated passing through lines 13, 14 into the heat exchangers 3, 4 respectively to heat the incoming feed water. The remaining water flows through a pipe 16 into the well 6. The wetness of the steam flowing to the superheater and hence the degree of superheat is controlled by a valve 15 regulating the water outflow from the separator 10 to the pressure-relief device 11.

Abstract: 957, 875. Washing machines; treating fabrics; vats. L. HALAUNBRENNER. March 26, 1962 [March 29, 1961], No. 11432/62. Headings D1A and D1L. A washing or dyeing machine includes a container for the material to be treated, the container having at least one deformable wall and at least one member adapted to deform said wall, the member and wall being set into relative movement by motor-driven transmission means. The deforming members are cylindrical rollers which are made to move over the deformable side wall(s) which are vertical coaxial circular cylinders thereby pressing in turn all the material in the container, either as in Fig. 3 by having the rollers 3 mounted on rods 4b spring-loaded in arms 4 fixed to a vertical motor-driven shaft 5, or by having one roller and no spring loading in an otherwise similar arrangement, or by using one or two stationary pairs of rollers, one roller being motor-driven to drive (by friction) the container about its axis between each pair. In the latter case, the container is supported either, as in Fig. 5 (not shown), by a horizontal flange 6c from one (rigid) wall resting on an annular roller bearing 5c, or, as in Fig. 7, from channelled sections 37 at the upper ends of the walls (both deformable) which rest in channelled sections of the outer casing. In the latter case, diametral stays 36 hold the upper parts of the two walls apart. Supports 18 of a pantograph type in a similar position are shown in Fig. 5 (not shown), in which also the rollers can be disconnected from their supports at one end and swung out about the other support for servicing etc. The container has a deformable bottom preferably with concentric circular pleats. Fig. 3 shows an intermediate rigid perforated wall 1b in the container, the material to be treated being confined between this wall and the inner deformable wall. Spring-loading, as in Fig. 3, of the supports of non-driving rollers can be done quite generally. A pump is provided to circulate the liquid.

IPC: A01J9/04
Abstract: 115,652. Robinson, P., (trading as Morton & Co., R.). March 7, 1917. Concentric or jacketed straight-tube apparatus; straight tubes between headers.-Relates to counter-current apparatus intended particularly for cooling milk, of the kind in which the cooling liquid flows in a zigzag course through a series of horizontal pipes connected by headers, and the milk flows through groups of small pipes inside the horizontal pipes. To prevent leakage of liquid through the pipe connexions in the headers, each group of internal pipes B is mounted in end collars 9, 10 secured by glands 14 in the headers. The gland at one end of a group of pipes presses an external flange 12 on the collar 10 against a dermatine or like packing-ring 15. At the other end, the collar may move longitudinally in the gland to allow the pipes to expand and contract. The hinged U-shaped tubular connexions E between the pairs of superposed headers bear against packing-rings 16 in the glands. Liquid leaking past the packing escapes through annular grooves 19 and radial holes in the glands. The hinge pins 27, Fig. 7, in a tubular connexion pass through lugs on the headers and through eye-bolts 28 secured to the connexion by nuts. Similar eyebolts engage with lugs 31 on the other side of the connexion.
