Filed: 1921-05-28
Abstract: 180,896. Schmidt'sche Heissdampf-Ges., and Hartmann, O. H. May 28, 1921. Superheating by steam.--In apparatus for superheating steam by means of a high-pressure medium, such as steam, at from 30 to 150 atmospheres, flowing through a tube system, around which the steam to be heated passes, the ends d, Fig. 1 of the tubes c which are disposed withiu a container A are closely packed together in the walls e of inlet and outlet chambers f in order to minimize the area on which the high pressure medium acts, and thus 'reduce the thickness of metal required. The tubes c are in the form of coils and are so arranged that the clear cross section for the passage of the steam to be superheated lies between one sixth and one half of the cross section of the container. The ccils c may be arranged in readily removable groups as in Fig. 4, each having its inlet and outlet chamber f<1>, f<3>. The coils may be wound in over-lapping right-and-left helices as shown in the central group in Fig. 4, or as shown in Fig. 1 where they are wound in helices one over the other. Steam to be superheated passes through the container A around the heating coils c in the direction indicated by the arrows. The coils c may be arranged so that each of them offers the same resistance to flow. In the arrangement shown in Fig. 1, a rod l holds the plstes e together and facilitates the ready removal of any coil of tubes. In the modification shown in Fig. 15, the inlet and outlet chambers f are arranged in a column s passing through the container and the heating medium is allowed to condense in situ, the condensate escaping by a valve controlled outlet. Specification 6308/11, [Class 64 (iii), Surface apparatus &c.], is referred to.

Patent GB-1133974-A (GB)
Title: Improvements in pneumatic control devices
IPC: B23B49/00
Filed: 1966-04-04
Abstract: 1,133,974. Winding webs. T. W. HAMILTON. 7 March, 1967 [4 April, 1966], No. 14911/66. Heading B6B. [Also in Divisions B3, G3 and H1] A device for producing a variable controlling air pressure comprises an air flow passage producing a Venturi effect and having an inlet 2 and an outlet 6 and an obstructor member 10 movable by a control mechanism in a direction transverse to the air stream between a position in which the flow through the passage is undisturbed and the Venturi effect produces a negative pressure in a control duct 9 and a position in which it extends at least partly across the air stream and causes the flow to become turbulent so that a positive pressure is produced in the control duct. The obstructor member is held out of the air stream by the air pressure acting on the underside of a piston 12 until the jet 35 between a pair of pipes 34, 36 is interrupted by an object 41. A change to positive pressure in the duct 9 permits a piston 18 and spool valve 20 to descend and supply air to a ram 32, which may set an automatic machine in motion to perform some operation on the object 41. Sintered bronze filters 4, 7 and 14, 15 are provided. The pipes 34, 36 may be connected to bores 52, 53 in a head 51 having a port 55 to detect the presence of webs of woven materials or molten metal levels. The device may be used to actuate a switch or a number of devices may be connected in parallel to detect the breakage of a drill or reamer in a fourspindle drilling machine. In a further application, two detector heads (35a, 35b, Fig. 7) serve the position of a web (74) being wound on to a roll (75) which is shifted axially by a motor (77) to maintain the web in the correct path. The heads (35a, 35b) and two devices (1a, 1b similar to that shown in Fig. 2 are connected to a common air supply (78) so that both inlet ports (79, 81) of the motor are vented to atmosphere when only the head (35a) is unobstructed. Movement of the web to cause both of the heads to become obstructed or unobstructed supplies air to the motor in the direction necessary to provide correction of the web position.

[Class 7 (ii)] [Also in Group XXXIII] In an aircraft or other engine comprising a circular group of cylinders 4, 5 with their axes parallel to that of the engine, a multi-stage turbo-compressor 18 is mounted on the end of a central air-inlet 1 remote from the inlet end thereof. The tube 1 constitutes the inlet for combustion air and may be non-rotating or may rotate and constitute the engine shaft. As shown diagrammatically, the cylinders are double-acting and,arranged in pairs in tandem. Combustible mixture is admitted by inlets 7, each common to an adjacent pair of cylinders, through slots 8 in the pistons 6 and through valve-controlled ports 9 in each piston to the combustion space at one or other end of the cylinder. Exhaust is through valved ports 10 into an exhaust pipe 11. The central inlet tube 1 is provided at the rear end with a Stromberg or other carburetter 12 having radially arranged fuel nozzles 13. A sleeve 14 slidable in the tube 1 carries a deflector 15 directing the mixture through slots 17 and an annular chamber 16 to the inlets 7 to the cylinders. Rotatably mounted on the rear end of the tube 1 is the multi-stage turbo-compressor 18, having four stages 18a .. 18d and driven by an exhaust turbine 20. The quantity of exhaust gas delivered to the turbine is adjusted by a regulating ring 21 adapted to by-pass part of the exhaust directly to an annular .chamber 22 having an outlet 23. Axial adjustment of the sleeve 14 brings the slots 17 into register in succession with the stages of the compressor 18, to determine the number of stages in use. Cooling air is admitted by pipes 25 to a chamber 24 around the compressor and passes through an annular chamber 26 to slots 27 in the air-inlet tube. The drive from the pistons may be transmitted to a propeller &c. by the means described in Specification 554,232.

Title: Continuous measurement of the fineness of a pulverulent material
IPC: G01N15/02
Filed: 1973-03-29
Abstract: 1390745 Measuring the fineness of pulverulent material CENTRE D'ETUDES ET DE RECHERCHES DE L'INDUSTRIE DES LIANTS HYDRAULIQUES 29 March 1973 [29 March 1972] 15086/73 Heading G1A In an apparatus for measuring the fineness of pulverulent material in the form of a homogeneous suspension 1 (Fig.1) a converging beam of radiation from a laser 2 is passed through the suspension and the diffraction pattern formed in the focal plane of the laser is investigated by photocells 5a, 5b at at least two points spaced from the focus of the laser beam. A ratio of the photo-cell output signals provides a measurement of the fineness of the pulverulent material. A suspension of the pulverulent material may be continuously formed in the laser beam path 24 Fig.2 by means of a compressed air conduit 7 discharging across one end of a further conduit 8 whose other end is immersed in the pulverulent material. Thus, the pulverulent material is drawn into an entrance chamber 6 of a convergent divergent nozzle 10 having a surrounding tube 11 for secondary air so that as the material passes through the nozzle it passes through a series of stationary supersonic shock waves which disperse and deflocculate the material. A blower 12 evacuates the suspension which has just passed across the laser beam path 24. Instead of sampling straight from a bed of the pulverulent material a small sample may be extracted from the material by a motorized screw and allowed to discharge into a funnel 15 (Fig.3) where some of it falls on a rotating disc 17 having an annular triangular cross-sectioned groove 21. As the disc rotates, the pulverulent material is' levelled out on the disc by scrapers 22 so that the parts of the disc emerging from the funnel 17 will only have the groove 21 filled with the pulverulent material. The pulverulent material in the groove 21 is then sucked out by a conduit 23 and dealt with as before.
