Abstract: 966,966. Dynamo-electric machines. ELEKTRO-MOTOREN A.G.- Sept. 6, 1960 [Sept. 7, 1959], No. 30764/60. Heading H2A. [Also in Division H1] A planar air-gap, single or poly-phase A.C. machine has stator poles of bent-over sheet metal excited by an annular field coil. In the single-phase machine shown in Figs. 1 and 2, the rotor of the machine is mounted on a common axle 51, the width of the air-gap being adjusted by means of a screw 54. The stator field coil 40 is enclosed in a series of sheet-metal strips 41 bent round it and passing through holes in an insulating carrier disc 44 to form the interdigitated poles 45, 46. The rotor is a disc 52 carrying a ring-shaped armature 53 which is permanently magnetized.,to provide a number of zones of alternate polarity around its periphery to correspond with the stator poles 45, 46. The stator poles may project in groups from single trough-shaped members. In a modification (Figs. 11-15, not shown) the machine has two rotors, one on either side of the stator, this being provided with two non-magnetic carrier discs each carrying apertures through which iron strips are passed to form two opposite rows of interdigitating polepieces. Both rotors carry a ring of permanent magnets. The two rotors may have different pole-numbers. Starting may be facilitated by wedge-shaped poles on stator and rotor. Alternatively (Fig. 21, not shown), the rotor may be axially resilient for this purpose. Single-phase motoring may be achieved by the use of shaded poles. In another modification (Fig. 28, not shown) short, non- interdigitated poles lie radially opposite each other in the same radial plane and the rotor poles are correspondingly disposed. The polar surfaces may be curved. In a two-phase form, Fig. 31, the stator two concentric field coils 601, 602 bounded by stirrups 604, 605 whose attached polepieces are offset to lie on a disc 608 and opposite to the armature ring 53 of the rotor. Such a machine may have two rotors (Fig. 34, not shown). The polar axes may be skewed instead of radial. The machine may have rotors on either side, selectively brought into operation by a D.C. electromagnet.

Title: Vapor fraction analyzer
IPC: G01N30/20
Filed: 1960-09-12
Abstract: <PICT:0922425/III/1> <PICT:0922425/III/2> In chromatographic gas analysis involving comparison of the thermal characteristics of the carrier gas and the mixture of carrier gas and a component separated therefrom, the sample gas is injected by filling a chamber with the sample gas and transporting all or a predetermined proportion thereof into a stream of the carrier gas.  Fig. 2 illustrates a preferred apparatus in which the carrier gas passes to the column through lines 26, 30 and bore 34 in piston 22 while sample fluid passes through lines 28, 32, bore 36 (the sample chamber) and channel 42 to vent. For injection the piston is moved until bore 36 co-operates with lines 26, 30, in which position sample fluid is still able to flow to vent through channel 42.  In the preferred sampling device shown in Fig. 4, the bore 36 is replaced by an axial bore 52 opening, in the position of the piston corresponding to Fig. 2, into the channel 42, said bore being connected to the interior of a bellows 90 the opposite end of which is connected to vent 96 having a valve 98.  The piston is positioned by means of an actuator 24 which moves the whole assembly between supporting plates 66, 68 which are rigidly secured together by means of rods 64.  When the piston is in the sample taking position valve 98 is open.  The valve is then closed and the piston moved into the injection position.  The bellows is then compressed by means of a second actuator 76 which moves plate 74 supported on rods 70 and bearing the right hand end attachment 93 of the bellows.  This is moved until it bears upon bushing 86, the position of which thus determines the quantity of sample injected. The bellows could be replaced by a piston and cylinder and the actuators may be pneumatically or solenoid operated.

Title: Improvements in and relating to a process for manufacturing articles from siliceous raw materials
Inventor: FELDER JOHN LAWSON
IPC: C03B13/14
Filed: 1968-07-03
Abstract: 1,209,655. Glass manufacture; siliceous aggregates; granulating miscellaneous minerals. J. L. FELDER. 3 July, 1968, No. 31669/68. Headings C1A and C1M. A method of forming an article from a primary argillaceous and/or igneous material, comprises introducing the primary material, preferably in particulate form, into a rotating kiln, heating the material substantially to its wet fusion temperature, tumbling the heated material to achieve agglomeration, forming the agglomerate into a unified mass, coating the unified mass with a particulate refractory material having a liquid fusion temperature above that of the primary material, heating the coated mass to a temperature above the wet fusion temperature of the primary material but below the wet fusion temperature of the coating, and rolling the coated unified mass into a cylindrical configuration. The primary material is fed into the upper end of an inclined rotary kiln 20. Kiln 20 is divided by screen 70 into a primary heating zone 80, in which the material is heated to its wet fusion temperature (e.g. 2000-2300‹ F.), and a final heating zone 82 in which the material is coated and heated to a temperature 150‹ F. above that of the primary zone 80. Each zone has its own burners, the waste gases exhausting up through the primary material feed shoot. The particulate refractory material, e.g. sand, quartz. granite, bauxite or sandy loam, is fed into the lower end of the kiln through a screw feeder 84 which spreads the material over the inner surface of the kiln. As the kiln rotates the primary material in the final heating zone 82 agglomerates and picks up a refractory coating from the material spread on the kiln wall. The heated coated unified mass agglomerates and is formed into a log 112 by two rollers 92. Thrust rollers 108 on the downstream end of rollers 92 continuously pull the log 112 from the kiln and feed it between two pairs of shaping rollers 118, 120, 132, 124 where it is flattened to a sheet and formed into balls joined by a septum. This sheet is fed into a rotary annealing kiln 131 during which the balls separate and can finally be collected and graded to size. If so desired they can be glazed within kiln 131. The final product is light in weight and can be fully bloated and so is useful for forming into building blocks and tiles. Both rollers 92 and thrust rollers 108 may be water cooled. A number of suitable siliceous compositions are given together with examples illustrating the speed of press-moulding the coated products to form final articles. The particulate refractory coating has a liquid fusion temperature at least 150‹ F. above that of the primary material. With igneous material, oxidizing, neutral or reducing atmospheres may be used in the kilns to change characteristics.
