Abstract: 576,458. Stud fastenings. SMITH & SONS (ENGLAND), Ltd., S., and HURN, F. J. Sept. 1, 1944, No. 16736. [Class 44] In a rotatable stud fastener of the kind having notches on the stud to engage abutments, e.g., spring abutments, on the other element, a key is engaged with the head of the stud to turn it, and means are provided to allow the key to be engaged and withdrawn only when the stud is in the locking position. For example, the key 21 has a spade-shaped end 22 which passes through a slot in one of the elements 15 to be connected, and engages in a slot in the head of the stud 16 when the latter is in such a position that notches thereon engage spring tongues 13 on the other element 12. On turning the stud to the release position shown in Fig. 2, the key is retained, and can only be withdrawn on turning to the locking position. The invention is stated to be applicable to the fitting of a mask or panel over an instrument support on a motor vehicle, as described in Specification 555,909, [Group XIX]. Specification 507,249 also is referred to.

Title: Electromagnetic waveguide transmission devices
IPC: H01P1/213
Filed: 1972-04-12
Abstract: 1359939 Branching filters; waveguide constructions WESTERN ELECTRIC CO Inc 12 April 1972 [16 April 1971 (2)] 16808/72 Heading H1W A waveguide band-separation filter or mode transformer comprises a segmental circular waveguide for transmission of the circularelectric TE 01  mode and band-pass filters mounted on the chordal surface of the segmental guide. As shown, the waveguide 10 is of semi-circular cross-section and is coupled by a slot 16 on the centre line of the diametral surface 12 to the first cavity 50 of a band-pass filter. This comprises rectangular cavities 50, 53, tuned to a desired band and coupled to an output (or input) waveguide 26. A band-stop filter, tuned to the same band as the bandpass filter 20, comprises rectangular cavities 51, 52 coupled to the waveguide 10 by central slots 17 ,18 and resonant respectively in the H 101  and H 102  modes. Energy in bands outside the regime of filters 20 and 30 is transmitted without change between ports 1 and 3 of the waveguide 10. Modifications are described in which the axes of the cavities of the bandpass and band-stop filters lie perpendicular to the axis of the waveguide 10. Such cavities may have either a rectangular or a circular crosssection. When the arrangement is used as a mode transformer (see Fig. 5, not shown), the port 3 may be terminated by a piston and the band-stop filter omitted. The whole of the input energy then passes into the band-pass filter. In the multiplexing arrangement of Fig. 4, a wideband input at A is divided into sub-bands by diplexers 71 and low-pass filters 66. Each subband is further sub-divided by channel-dropping filters 70 connected to amplification or utilization devices 65. The channels may be recombined in an output arrangement which is identical to the input arrangement and it is apparent that the whole multiplexing arrangement operates reciprocally. The device of Fig. 3, may be made by an electroforming process using non-destructible stainless steel mandrels for the formation of cavities 50, 51, 52, 53 and waveguide 26. The electroform consists of two slabs with mating surfaces co-inciding with the common median plane of the cavities and the waveguide (see Fig. 6, not shown). The curved wall of waveguide 10 is provided by a further electroform and the chordal wall 12 by the undersurface of the lower of the two slabs providing the filters. The slabs are located by pin-and-slot, and a sealing gasket is located in a peripheral groove in the upper slab.

Abstract: Compounds of the general formula <FORM:0692413/IV (b)/1> where Ar is an ortho arylene radical, R is an alkylene group and n is an integer, for use as pickling inhibitors, are prepared by introducing into 2-mercaptoarylenethiazoles one or more hydroxyalkyl radicals.  The former may be 2-mercaptobenzothiazole, 2 - mercaptonaphthothiazole, 2 - mercapto - 4 - phenylbenzothiazole, 2 - mercaptochlorobenzothiazole or 2 - mercaptotolylthiazole and condensation may be effected with ethylene oxide, propylene oxide, glycide, epichlorhydrin, glycol, glycerine or polyglyamine or two such compounds may be caused to react consecutively.  Alkaline reacting agents or nickel sulphate may be employed as catalysts.  In an example, 2-mercaptobenzothiazole is dissolved in dioxane, absorptive carbon added and ethylene oxide passed into the solution at 96-105 DEG  C.; insoluble material is, when reaction ceases, filtered from the hot solution, solvent removed and the residue heated to 90 DEG  C. under 5 mm. pressure.  The product is then recrystallized from benzene.  Alternatively, monochlorobenzene, orthodichlorobenzene, tetrachlorobenzene or the diethyl ether of diethylene glycol may be used as solvent.  The reaction of mercaptobenzothiazole with ethylene oxide in varying ratios in the presence of caustic potash is also described to yield products in which n varies from 1-15.  Products may also be prepared as described in Specification 692,414.ALSO:Ferrous metals are pickled in a mineral acid solution containing a small proportion of a compound of the formula <FORM:0692413/II/1> where Ar is an ortho arylene group, R is an alkyline radical and n is an integer: R may be an ethylene group and n may be between 5 and 31.

Abstract: An olefin polymerization catalyst comprises the oxides of aluminium and silicon and one or more oxygen-containing compounds of a metal or metals of Group VA, the compound or at least one compound containing the metal in a valency state lower than 5. The proportion of Al2O3 in the Al2O3-SiO2 is preferabl 5-65, particularly 5-35, e.g. 12 or 25, wt. per cent.  The Group VA component may be introduced as a pentavalent compound and reduced with a gas such as hydrogen, carbon monoxide or a hydrocarbon at above 300 DEG  C., particularly below 650 DEG  C., especially 400-550 DEG  C., e.g. 500 DEG  C.; prior to impregnation, the Al2O3-SiO2 may be activated at 500-750 DEG  C., using air, other oxygen-containing gas or inert gas, preferably together with water vapour.  The catalyst is preferably employed in a liquid hydrocarbon medium, but in the absence thereof may be fluidized or used in a fixed or moving bed. The catalyst is reactivated, after cleansing with solvents (e.g. hydrocarbons or chlorinated hydrocarbons) by "conditioning," i.e. reducing the catalyst (as above), but at lower temperatures (e.g. below 300 DEG C., even below 100 DEG  C.), if necessary burning off combustible deposits prior to said "conditioning."  The catalyst may be in the form of cylinders, spheres, coarse grains or lumps, but preferably comprises microspheroidal grains of 10-200, e.g. 20-120, microns.ALSO:Olefines, including mixtures thereof, are polymerized by use of a catalyst comprising a lower valency Group Va oxygen-containing compound supported on Al2O3-SiO2; the olefins are aliphatic, preferably of 2-5 carbon atoms, e.g. ethylene and propylene.  The polymerization is preferably effected in an inert liquid hydrocarbon, particularly saturated aliphatic, such as iso-octane, but aromatic hydrocarbons are also mentioned, as is gas-phase polymerization.  The process may be continuous or carried out in batches, and preferably at 50-200 DEG  C.
