Title: Improvements in cavity resonators
IPC: H01P7/06
Filed: 1947-07-04
Abstract: 639,008. Electric resonators. WESTERN ELECTRIC CO., Inc. July 4, 1947, No. 17688. Convention date, Aug. 1, 1946. [Class 40 (viii)] A cavity. resonator has means located along a nodal plane of a desired mode of oscillation which dissipates energy of an undesired mode. As shown, a resonator 10 is provided with a tuning piston 18 and two discs 33 and 34 are supported in the resonator along nodal planes. The discs may comprise a sheet of dielectric material and the loss they cause to an undesired mode may be increased by providing them with a conducting coating. Asthe position of the nodal planes will change slightly with movement of the tuning piston 18, the discs 33 and 34 may be made adjustable by passing their supporting pins 38 through slots in the resonator wall and securing them by a clamping ring outside. Further discs 35 and 36 may be provided on other nodal planes. In an alternative construction slots may be cut in the resonator wall along a nodal plane to permit energy of an unwanted mode to leak out of the resonator.

Abstract: To separate ethylene from the gas obtained in the dry distillation of fuels, the gas is first freed from tar, ammonia, and benzene, and then passed at a temperature of 0 to -20 DEG  C. over substances having a large superficial area, for example absorbent carbon.  The fraction enriched with respect to ethylene is, if necessary, expelled, collected, and re-absorbed as before to obtain a further enrichment, and this process may be repeated.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the separation of the other constituents by a similar process, and to a process of selective absorption in which the gas is passed over a plurality of absorbent masses at different temperatures.  This subject-matter does not appear in the Specification as accepted.ALSO:Ethylene is separated from the gas obtained in the dry distillation of fuel, by passing the gas freed from tar, ammonia, and benzene, over substances having a large superficial area, for example, absorbent carbon, maintained at a temperature of 0 to -20 DEG  C.

Title: Monoazo dyestuffs of the benzene-azo-2-tetralol series and metal complexes thereof
IPC: C09B45/14
Filed: 1956-06-15
Abstract: The invention comprises dyes of formula <FORM:0836995/IV(c)/1> where X is H, Hlg, or SO2NR1R2, where R1 and R2 are H, alkyl, hydroxyalkyl or linked to form a heterocyclic ring with N, and their 1,2-metal complexes.  Chlorine is a preferred halogen.  Specified alkyl groups are methyl, ethyl, isopropyl, n-propyl, butyl, isobutyl and n-butyl. Specified hydroxyalkyl groups are hydroxyethyl, -propyl and -butyl. A sulphonmorpholide group is given as a heterocyclic containing R1 and R2.  The dyes are made in conventional fashion by coupling appropriate diazo compounds with 2-tetralol and metallizing if desired.  Metallization may be effected in substance, on a substratum or in situ.  Illustrative of diazo compounds which may be used are those derived from 4-nitro- and 4-nitro-6-chloro-, -sulphoanamido -, - N - hydroxyethylsulphamyl -, - N,N - dimethylsulphamyl - N,N - bishydroxyethylsulphamyl - and - N,N - diethylsulphamyl - 2 - aminophenol.  Indicated metals are those of atomic weights of 52-64 e.g. Cu, Ni, Fe, Cr and Co, the last two being preferred. The metal dyes colour silk, leather, cellulose esters and ethers, terephthalate polyesters and polyacrylonitriles but are especially of use for dyeing wool and nylon.  They also colour natural or synthetic resins, organic solvents, stains, varnishes and lacquers.  Dyeing is preferably effected by a dispersed-dye method.  Examples are provided of the preparation of the dyes and their use in dyeing processes. Specifications 404,413, 709,495 and 753,987 are referred to.

Title: Improvements relating to the construction of pressure vessels
IPC: B01J3/03
Filed: 1954-06-24
Abstract: 769,216. Doors for resisting fluid pressure. LEEDS & BRADFORD BOILER CO., Ltd., and PICKARD, H. M. H. June 22, 1955 [June 24, 1954], No. 18557/54. Class 123 (1). In a pressure vessel, such as a sterilizer or autoclave, a seal is effected between the door and the mouth of the vessel such that pressure in the vessel may be relieved via a safety or relief valve while ensuring that, when the vessel is under vacuum, the vacuum cannot be broken through the safety valve but only through a separate valve. The invention is shown applied to the door described in Specification 412,700 wherein a series of pivoted locking latches 12 disposed around a base ring 10 secured to the vessel rim by bolts 11 are adapted to be swung into and out of operative position by a surrounding rotatable ring 14. The door 22 has a double seal consisting of a flat ring 17 held in a recess in a flange 15 formed inside the base ring and engaged by the lower edge 24 of the door and a lip type sealing ring 21 held in a groove 20 in ring 10 and engaging the tapered outer periphery 25 of the door. Between the seals is an annular space 26 which is connected with the relief or safety valve, not shown, via a bore 27. When the vessel is put under pressure, the edge 24 lifts slightly from the ring 17 so that the vessel can be vented through the valve. When the vessel is under vacuum, the edge 24 is pressed on to the ring 17 cutting off the space 26 from the vessel interior, the space then being at atmospheric pressure since seal 21 is no longer effective. To break the vacuum a pipe leads from the vessel to a three-way valve 28 by means of which it may be placed in communication with atmosphere through a pipe 29. When the vessel is used as a sterilizer, air enters pipe 29 through a cup 30 containing a sterilizing agent. The three-way valve 28 also controls the application of pressure or vacuum from pipes 35, 36 and may be interlocked with the door mechanism in the manner described in Specification 667,929 to prevent the admission of steam until the door is properly closed and to prevent premature opening of the door.

Abstract: 315,980. Hepburn, D., and Whall, H. B. June 27, 1928. Receptacles, detachably securing to flat bases.-One end of a flexible member to be strained, which may be a strap 3 for securing a trunk &c. 1 to the luggage grid 2 of a car, is secured to a cranked lever 8 the pivot 9 of which is offset, so that, in straining the lever passes over a dead centre position and becomes held against further forward movement in a position defined by the engagement of a stop 12 in a notch 13 in the lever. The other end of the strap and the plate 10 to which the lever is pivoted are formed with hooks 5, 11 to engage the luggage grid. Means for adjusting the length of the strap and the point of attachment to the lever may be provided and instead of the pivot axis of the lever being parallel to the plane of the strap &c. it may be at right angles or other inclination thereto. Instead of the strap passing over the trunk, two short sections 18, 19, Fig. 2, each of which is secured to the trunk and connected to a cranked lever may be provided. A handle 14 may be fitted. The tension on the strap normally prevents reverse movement of the lever over the dead centre to release the tension, but positive locking means may be provided to prevent accidental displacement of the lever. In the modification shown in Fig. 3, the lever 8 and plate 10 are replaced by stiff wire members 20, 21. The apparatus may be applied to guy ropes for masts &c. or for holding down loads on lorries or railway waggons. Specification 139,467, [Class 44, Fastenings, Lock &c.], is referred to.
