Title: Device for producing a beam of monochromatic x-rays
IPC: G21K1/06
Filed: 1947-08-08
Abstract: 650,788. X-ray apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 8, 1947, No. 21909. Convention date, Aug. 8, 1945. [Class 98 (i)] A device for producing a monochromatic beam of X-rays comprises a holder having a concave surface which forms part of a circular cylinder and is covered with a layer of powdered crystalline material which reflects X-rays of a determined wavelength emanating from a source on the cylinder so as to bring them to a focus at a target on the cylinder. As shown, the surface of a holder 1 is part of a cylindrical surface at a point A on which lies a non-monochromatic source of X-rays, the width of the beam and the effective length of the source being restricted by a diaphragm 3. The ray from A striking the crystal surfaces at B is reflected at the Bragg angle and meets the cylindrical surface at C. From geometrical considerations, it is shown that a ray striking the surface at any other point, e.g. D, and reflected at the same Bragg angle passes through the same point C. A line drawn through C, perpendicular to the plane of the Figure, may therefore be regarded as a secondary source of monochromatic X-rays. The crystalline powder preferably consists of a substance forming crystals with one axis much longer than the others, such as acetates of heavy metals, e.g. silver or mercury, and may be mixed as a paste with a non-crystalline binding material, such as collodion, polyvinyl alcohol, or a solution of methylcellulose in water or of polystyrene in ether or alcohol, for application to the holder. The X-ray source may comprise an X-ray tube so arranged that the emitting anode surface extends parallel to the generatrices of the cylindrical surface and makes an angle less than 10 degrees with the line AE. Specification 637,744 is referred to.

Title: Method and apparatus for compressing and packaging material
IPC: B65B63/02
Filed: 1966-05-18
Abstract: 1,133,147. Packaging fibrous material. OWENS-CORNING FIBERGLAS CORP. 18 May, 1966 [18 May, 1965], No. 22043/66. Heading B8C. Fibrous material, e.g. glass fibre mats, is compressed by withdrawing air from it and then either wrapping or bagging it in the compressed state, the compression being augmented by mechanical means. In one embodiment, Fig. 2 (not shown), fibre mats resting on an apertured plate (40) withdrawing air, are further compressed by a ram (42) against an end plate (41). In an apparatus for bagging or banding fibre mats, stacks of the latter 54 are withdrawn from an infeed conveyer 50 by a horizontally reciprocating suction plate 60 and positioned between plates 51, 55 and on a suction platform 80, Fig. 4. A ram 70 assists the suction in compressing the stack against the platform which descends between the arms 91(a), 91(b) of a forked pusher 90. Additional stacks may be forced down on the platform to form a bale. When the platform is below the arms, the pusher moves forward, its arms applying suction to the stacks to retain them and the platform (80) which remains stationary, going over to air pressure to reduce friction with the base of the moving bale. The ram 70 may likewise be arranged to discharge air. The arms pass between guides 101, 102 of a bag or sleeve support 100, the bag or sleeve being clamped in position by means 104 and lying beneath a hinged plate 121, apertured to discharge pressure air. Beneath is a discharge conveyer belt 111 below which pressure air may be discharged by a plenum 113. As the pusher 90 withdraws, the arms 91a, 91b go over to air pressure so that they may move without retracting the bale. Finally, to assist discharge, air is blown from the plate 121 and plenum, and the belt 111 withdraws the finished package. A coil of fibre mat may be formed on a spindle between end plates having air-withdrawing suction apertures, Figs. 9, 10 (not shown), the mat being tensioned to compress it.

Abstract: 1316673 Casting processes SULZER BROS Ltd 7 May 1970 [8 May 1969] 22075/70 Heading B3F A method of casting comprises evacuating a mould cavity 33 admitting a gas other than air to the mould cavity, connecting the mould cavity to a melt 31 of the casting material, evacuating the mould cavity to cause the casting material to rise in the cavity, and disconnecting the cavity from the melt 31 while avoiding discharge of casting material from the cavity. The mould 2 may be mounted in a housing 1 which is evacuated through a pipe 14 and a regulating valve 18, the upper part 11 of the mould being made of porous material and provided with ducts 13. The gas is introduced into the housing 1 from storage vessels 24 and 40 and may be a protective gas, e.g. He, Ar, CO 2 , or a gas which reacts with the casting material, e.g. H 2 , CO or HCl. It may be heated before admission to the mould. The end of the inlet 6 is closed by a hood before connecting the mould cavity to the melt. The hood may be made of a material which will melt when immersed in the casting material 31. To prevent discharge of the casting material from the mould after the mould is separated from the melt, a gate or valve may be provided or the mould may be rotated so that centrifugal force causes the material to be retained on the walls of the mould cavity, or the air pressure acting on the metal in the opening 34 may be sufficient.

Title: Noise suppression in radio receivers
IPC: H03G3/26
Filed: 1933-08-08
Abstract: 423,194. Valve amplifying circuits. MURPHY RADIO, Ltd., ELLIS, H. D., and BAKER, G. B., 62, Brook Street, Hanover Square, London. Aug. 8, 1933, Nos. 22192/33 and 22089 /34. [Class 40 (v)] A method of suppressing noise in radio receivers having automatic volume control consists in positively biassing to a condition of low stage gain an amplifying-valve of the receiver, and superimposing a negative bias derived from rectification of the amplified signal. In the Figure an amplified high frequency signal is applied to circuit 38 of the rectifying diode 39, the resulting potential across the resistance 40 being applied to the control grid of triode 42 whose anode circuit includes resistance 43. When the received signals are below a certain intensity level, the grids of the high frequency amplifiers 23, 24 are positively biassed by the voltage drop across part 47 of the supply potentiometer, the control diode 44 being inoperative since the potential of point 48 is positive with respect to 49. As signal strength increases, 48 becomes negative with respect to 49, the diode 44 passes current and the resulting voltage drop across resistance 45 opposes that due to 47 thus reducing the positive bias on 23, 24 and increasing the gain; the effect is thus cumulative. The voltage determining the signal level at which the receiver becomes active is the difference between the potentials across part 46 of the potentiometer and resistance 43 with no signal.

[Class 46.] In a process for treating one liquid with another in which the liquids are mixed continuously in a definite proportion, kept in admixture for a definite period and then passed to a separator, the liquids are mixed on or before entering the treatment chamber but are not subjected to prolonged agitation therein and the speed of travel through the chamber is such that the treatment is completed therein each of the liquids passing once only through the chamber so that each portion of liquid receives the same treatment and the portions of liquid leave the chamber in substantially the same order as they enter. With apparatus as shown in Fig. 1, the liquids are delivered by passages 1, 2 to a chamber 3 and mixed by means of an atomizing nozzle 10. Perforated partitions 7 with baffles on the outlet side of the perforations are placed at intervals in the chamber 3. The mixed liquids pass to a separating vessel 4 with outlets 5, 6 for the lighter and heavier liquid respectively. Porous partitions may replace the perforated partitions 7 or the chamber may be packed with material in loose particles, or have stirring devices whose action is restricted to very short zones. Several of such sets of apparatus may be arranged to form a battery, the liquids being passed from set to set in countercurrent by means of pumps or under the influence of pneumatic pressure or suction and the flow being regulated by means of adjustable cocks. Fig. 7 shows a battery in which the chambers 3 are connected to a single suction line 17. Associated with each settling vessel 4 are tall narrow storage vessels 26, 27 receiving light and heavy liquid respectively. When the pipe 17 is connected to suction a valve 18 at the bottom of each chamber 3 is opened and heavy liquid is drawn from the vessel 27 of the preceding set through a nozzle 10 and light liquid is drawn from the vessel 26 of the succeeding set. The liquid in the chamber 3 rises from the level I to the level II. On releasing the suction valves 22 open and the mixed liquids pass to the settling vessels 4 until the liquid in the vessels 3 has fallen again to the level I.
