Title: Method and machine for weaving of fin-and-tube radiators
IPC: B21D53/08
Filed: 1961-07-24
Abstract: 936,167. Making radiators. SEPARATOR A.B. July 24, 1961 [July 22, 1960], No. 26703/61. Class 83 (2). A method of making fin-and-tube radiators comprises intermittently moving a number of parallel spaced fins with tube-receiving apertures through guide means and at each dwell period when the apertures are in alignment a tube is driven through guide means into the apertures. Fin strips 35, Fig. 4, with two rows of tube-receiving apertures 36 are fed between spaced vertical guide plates 57 in a fixture 1 by gripper means comprising fingers 33 and 34 depending from and upstanding from plates 31 and 32 respectively. The plates are actuated so that the fingers move towards each other to engage between tubes 37 previously inserted through the fins while the apertures were in alignment with slots 59 and 60 in the fixture 1 and then perform a feeding movement to draw the fins further through the fixture. The fingers then move apart and return to their starting positions. The tubes are loaded manually into a curved magazine 2, Fig. 3. A member 4 reciprocated on rollers 16, 17 between guides by a pneumatic cylinder assembly 3 carries members 14 and 15 for pushtubes through the fins apertures aligned with the slots in the fixture 1 and also carries a cam rail 5 co-operating with follower rolls 25, 26 to impart the feeding movement to the plates 31, 32 against the action of return springs 29, 30. The movement of the plates into and out of gripping engagement with the finned tubes is effected by pneumatic cylinder assemblies 9 and 10 which, together with the assembly 3 are actuated by a valve 42 controlled from a limit switch 43 as it abuts stops 44, 45. A modified apparatus, Figs. 7-9 (not shown), inserts three rows of tubes in correspondingly apertured strips. For continuous operation a number of fin strips are joined end to end, the joints of adjacent strips being staggered, and the completed fin and tube assembly is cut to the required length on emerging from the assembly machine.

Abstract: 281,448. Adsero, J. Oct. 26, 1926. Catch gear of mine-cage type. - Safety catch gear for mine-cages &c., of the kind in which guide grips are mounted on a carrier which is separable from the cage, has the grips connected to the cage by tapered ropes which by reason of the taper become gradually wedged between the guides and rollers or other abutments and so support the cage when the hoisting rope &c. breaks. The hoisting rope bolt 12 passes through the top of the cage 1, a spring 13 being fitted to the lower end of the bolt between a bearer plate 14 on the cage and a cross-plate, 15 on the bolt. Levers 16 pivoted to the cross-plate pass through eyeletted rods 17 depending from cross shafts 5 mounted in a carrier frame 4 separably mounted on the top of the cage by means of dowel pins 6. When the hoisting rope comes into action, the spring 13 is compressed, the levers 16 contact with fulcrum ribs 24 on the roof of the cage and by means of the eyelet rods 17 hold the carrier frame against the cage. When the hoisting rope breaks, guide gripping arms 8 mounted on shafts 7 are pressed against the guides 2 by springs, so detaching the carrier frame! from the cage and as the cage moves downwards it is gradually brought to rest by the increasing force exerted on tapered ropes 20 connected at their thin ends to the shafts 7 and passing between the guides 2 and rollers 21 or other abutments on the cage.

Title: Improvements in and relating to a process for the oxidation of organic compounds to carboxylic acids and other products
Inventor: GOFTON BERNARD FENWICK
IPC: C07C51/34
Filed: 1957-08-26
Abstract: In a process for the production of organic carboxylic acids by the oxidation of hydrocarbons and their oxygen and halogen derivatives, and of alkyl heterocyclic compounds of aromatic character, in the liquid phase by means of molecular oxygen or ozone in the presence of a catalyst comprising a bromide of a metal of variable valency, the oxidation is carried out in a reactor fabricated or lined with an alloy containing nickel as its main constituent and also comprising substantial amounts of molybdenum, chromium, tungsten and iron, whereby corrosion problems are obviated.  In Example 2, p-xylene, dissolved in acetic acid, containing a small proportion of manganese and cobalt bromides is subjected to oxidation in such a reactor, at a temperature of 150 DEG  C. and a pressure of 50 p.s.i.g., by means of oxygen, to give a 90% yield of terephthalic acid of good colour. The other examples relate to the preparation of ortho- or tere-phthalic acids, and describe comparative corrosion tests using other alloys. Other oxidation processes referred to are: the oxidation of cyclohexene, cyclohexane or cyclohexanone to obtain adipic acid, the oxidation of toluene, cumene, benzyl alcohol, benzaldehyde or acetophenone to obtain benzoic acid, the oxidation of the methylnaphthalenes and the methyl pyridines to obtain the naphthoic and pyridinic acids, respectively; the oxidation of methyl p-toluate to give methyl hydrogen terephthalate, the oxidation of mesitylene to give trimesic acid, the oxidation of the paraffins to yield butyric, propionic, acetic and formic acids, and the oxidation of beta-beta1-di-chloro-di-ethylether to yield beta-chlorethylchloracetate and chloracetic acid.  Specifications 804,612, 824,116 and 837,006 are referred to.

Abstract: 963,776. Granulating thermoplastics. IMPERIAL CHEMICAL INDUSTRIES Ltd. July 1, 1963 [July 13, 1962], No. 26998/62. Heading B5A. Thermoplastic polymers with melting points of above 100‹ C. are granulated by extruding the molten polymer through rod or threadforming orifices into a cooling liquid, and then cutting the extruded material transversely into granules whilst it is immersed in the liquid, before its complete solidification, the cooling liquid being at a temperature between 100‹ C. and the freezing point of the polymer in order to solidify at least the surface of the cut granules. Suitable polymers are polyamides, polyacetals and solid polymers of mono-α-olefines, especially isotactic polypropylene. Suitable cooling liquids are ethylene glycol or ethylene glycol/water mixtures. The temperature of the cooling liquid may be varied depending upon the polymer temperature and the extrusion rate. It is preferred that the cooling liquid density should not be less than that of the polymer in order to facilitate the latter's removal. An example of the granulation of polypropylene is given. Specifications 774,681, 829,152 and 918,609 are referred to.
