Abstract: 872,341. Spring assemblies. BENJAMIN, C. M. March 31, 1960 [April 8, 1959; May 8, 1959; June 30, 1959], Nos. 11881/59, 15910/59 and 22460/59. Class 52(4). A "spring edge" assembly is formed by a plurality of inclined spring elements 1 held at one end by a bar 3 and at the other end by a wire 4 to which are attached a plurality of elastic webs 9 and either elastic or non-elastic webs 11. The assembly may be used at the front of a seat (Fig. 1) or to form the side of a divan frame (Fig. 4) or may form the top edge also of a chair back (Fig. 6). The bar 3 may be channel-shaped or may have lugs to engage the ends of the spring elements 1 which may be V-shaped as in Fig. 9. The elements 1 may be connected by T-shaped clips instead of the bar 4 and the webbing may have claws to be hooked on to the spring elements.

Title: Manufacture of polymeric products from vinyl aromatic hydrocarbons
Inventor: HAWARD ROBERT NOBBS
IPC: C08F12/04
Filed: 1954-04-23
Abstract: Vinyl aromatic hydrocarbons e.g. styrene and vinyl toluene, are polymerized and simultaneously reacted with a partially alkylated aromatic hydrocarbon which is liquid under the conditions of the reaction and in which the vinyl compound is soluble, in the presence of an activated earth or clay catalyst, e.g. acid activated Florida earth, bentonite, montmorillonite and hydrosilicates by gradually adding the vinyl compound to the partially alkylated aromatic hydrocarbon containing the catalyst so that the concentration of unreacted monomer does not at any time exceed 1 percent by weight. The partially alkylated aromatic hydrocarbon contains at least one alkyl nuclear substituent group and at least one unsubstituted nuclear hydrogen atom, e.g. methyl and ethyl benzenes and naphthalenes.  Preferably the vinyl hydrocarbon is dissolved in the alkylated hydrocarbon and added to a suspension of the catalyst in a further quantity of alkylated hydrocarbon.  Examples describe the polymerization of styrene and m/p-xylene, using mineral acid activated montmorillonite clays contained in m/p-xylene by heating at 100 DEG C. under carbon dioxide or nitrogen.  The reaction mixture is filtered and distilled under vacuum to give products containing 9 to 50 percent of partially alkylated aromatic hydrocarbon in reacted form.  The liquid products may be used as plasticizers or extenders for vinyl plastic compositions, e.g. polystyrene, or as heat transfer media, and the solid products may be used for surface coatings or floor tiles.

Abstract: 271,072. Albert, A. May 15, 1926, [Convention date]. Thermostats. - An alarm device adapted to operate either on a sudden rise in temperature or at a predetermined temperature, comprises a lever 8, 9 pivoted near one end to a support 6<1> and also pivoted at its short end 8 to a metal rod 4 mounted on a plate 1 of material which is a poor conductor of heat and electricity. The long arm 9 of the lever has at its free end a contact point and a second rod 6 similar to the rod 4 and adjustably mounted on the plate 1 has at its free end a contact 10. The support 6<1> is carried by a rod 5 thicker than the rods 4 and 6 and it has a contact arm 16 adapted to engage a screw 15 in electrical connection with the rod 6. The rods 4 and 5 are in electrical connection, and the rods 4 and 6 have terminals 11, 13 in an electric circuit 12.

Abstract: 1370720 Gas turbine engines noise suppression GENERAL ELECTRIC CO 16 March 1972 [26 April 1971] 12359/72 Headings F1G and F1J The invention relates to a method of attenuating the noise in a gas turbine engine wherein an auxiliary sound source capable of generating sound energy in the ultrasonic frequency range is disposed within the engine such that the ultrasonic sound energy modulates the audible sound energy generated within the engine to produce new tones in the inaudible range. The engine shown is a gas turbine ducted fan engine the fan of which comprises rotor blades, 28, 30 and inlet and outlet stator blades 41. Ultrasonic sound generators 48 are disposed in the wall of the fan duct casing 34 as shown and generate an inaudible sound having a frequency of 25, 000 Hz while the blade passing frequency of the fan blading is 3, 000 Hz. The new tones generated have a frequency of 28, 000 Hz (the sum) and 22, 000 Hz (the difference). Thus the audible tone has been eliminated.

Abstract: 1315911 Moulding sliding clasp fasteners TEXTRON Inc 3 May 1971 [4 May 1970] 12706/71 Heading B5A [Also in Division E2] A method of manufacturing a slide fastener whereby top end stops are formed comprises the steps of passing each stringer tape 12, Fig. 7, through a slot 93, 93<SP>1</SP> in a block 78 until the end portion of the tape without elements 20 lies adjacent cavities 122, 122<SP>1</SP> whereupon pieces of stock fusible material 92, 92<SP>1</SP> are passed through bores 91, 91<SP>1</SP> until they abut wall 96. Fusing member 124 is lowered and pushes the block 78 against springs 110 so that the pieces of stock 92 are severed near their ends and are contained within cavities 122 by the legs 102, 104 of anvil 100 fixed in base 106. Ultrasonic energy is supplied to member 124 and this is transmitted via legs 130, 130<SP>1</SP> to the pieces of stock 92 so that they fuse to the shape of the cavities 122 and on to the tape ends to form the end stops 24, 26. Fusing member 129 is then retracted. Prior to this action the end elements 38-44, Fig. 2, may be deformed and reduced in size so as to accommodate the slider "diamond" 36 when in its uppermost position in order to prevent unsightly splaying of the tape ends. This is achieved by threading the tape ends into slots 50, Fig. 5, of block 46 and deforming the end elements 38-44 by means of an ultrasonic horn 64 having two sets of cavities, e.g. 74, 75 being pressed against the block 46.

Title: A method and an apparatus for glazing recessed articles of ceramic material

Abstract: 1,211,300. Glazing ceramic articles. H. SELTMANN, F. FALTISS and E. MULLER. 15 March, 1968 [15 March, 1967], No. 12843/68. Heading C1M. In a method of glazing recessed ceramic articles, e.g. drinking cups, the articles are supported on a travelling conveyer in point contact therewith and with their recesses facing upwards, and are continuously moved through at least two film-like curtains of liquid glazing material one of which wets the article from above and the other from below, surplus glazing medium collecting in the recesses being removed by a jet of air directed downwardly on to the upper surfaces of the articles, surplus glazing medium collecting on the lower portions of the article also being removed. Porcelain cups 1 with their recessed bases uppermost are carried on an upwardly inclined conveyer 3 in point contact with their rims 2 through three film-like curtains of glazing medium 5, 6, 7, curtains 5 and 7 falling and curtain 6 rising below the cups 1. The descending curtains are formed by glazing medium flowing from a container 17 over two sets of weirs 21, 22. Each of these weirs may be preceded by a further weir of weirs 23 to obviate any pressure variations in flow. The curtain 6 is formed from a slit nozzle 24 located beneath the conveyer 3 and between, curtains 5 and 7. After passing through all three glazing curtains excess glaze which has collected in the base recess of the cup is blown out by air from a nozzle 41 operated by a photoelectric device 42. The conveyer 3 comprises at least two parallel endless bands of, for example, circular or triangular cross-section and preferably immediately after passing the air nozzle 41 the articles are transferred to a second conveyer 3<SP>1</SP> also formed from at least two endless belts. This changes the point contact of the rims. On this second belt the articles pass over a suction device 26 which removes surplus glaze collecting around the article rims 2. The surplus glaze from the articles and from the coating curtains is collected in a bath 29 and returned to a feeder tank 31. Glaze from this tank is pumped to the slit nozzle 24 and the container 17. In an alternative embodiment the articles are retained during the whole of the operation on the conveyer 3, but after passing through the three glazing curtains the conveyer 3 runs over and in contact with a further endless belt. This second belt for part of its travel passes through a bath of the glaze and so ensures that the rim of the article is evenly coated excess glaze being removed by wetting as the conveyer 3 moves out of contact with this second belt.
