Title: Anti-vibration mountings for machines
IPC: F16M7/00
Filed: 1971-09-21
Abstract: 1368630 Machine supports G CHADWICK 20 Sept 1972 [21 Sept 1971] 43860/71 Heading F2X  An anti-vibration mounting for a machine, e.g. a compressor, is made by casting a number of plinths, e.g. plinth 20, in situ from reinforced concrete on a foundation 28. Bores 24 for receiving holding down bolts 26 for the machine are then drilled through the plinths and into the foundation 28 by means of a diamond tipped bit 25. A jig 1 in the form of a rectangular frame and provided with height adjusting means and location holes 2 extending through reinforcement pads 3 is levelled over the plinths with the holes 2 in alignment with the bores 24. Epoxy resin composition 29 is poured into the bores 24 for bonding bolts 26 in position over their lower portions and rubber sleeves 30 are placed over their upper portions and sealed with foam rubber 31. The jig 1 is then removed from the plinth, foot plates 11 attached by means of bolts screwed into threaded apertures 10 adjacent each pad 3, and the jig 1 again levelled over the plinths with the foot plates 11 suspended in prepared recesses 27 at the bolt locations. Epoxy resin composition 32 is poured into the recesses 27 so that the foot plates 11 are immersed in the composition, the bolts are removed from the apertures 10, and the jig 1 is removed leaving the foot plates 11 in situ. The installation has the advantage that the foot plates 11 are set in position when the machine 33 arrives for mounting and the bolts 26 are subject to a minimum of stress, shear stress caused, e.g. by lateral components of vibration being converted to a bending stress over the upper portions of the bolts. Foamed rubber 34 is inserted between the plinth 20, the resin composition 32 and the machine 33.

Title: An apparatus and method for longitudinally stretching continuous films of thermoplastic materials
Inventor: REST WILHELM
IPC: B29C55/06
Filed: 1966-09-30
Abstract: 1,126,693. Stretching films longitudinally. FARBENFABRIKEN BAYER A.G. 30 Sept., 1966, No. 43882/66. Heading B5B. An apparatus for stretching film webs longitudinally in a continuous manner comprises an internally heated feed roll 1 (Figs. 1 and 2) positively driven at a peripheral speed equal to the linear speed at which a film web 3 is delivered on to the roll in the unstretched condition, an internally heated draw roll 2 positively driven at a peripheral speed several times that of the feed roll 1. A wedge (shown in cross-section at 8) whose length in a direction normal to the plane of the drawing is not less than the width of the film is arranged in the space between the rolls 1 and 2 on the side of the gap 4 between the rolls at which the film enters the gap to ensure that the layer of hot air 7 carried along on the surface of the roll 2 is directed towards the gap 4. Stretching takes place in this gap between the line 5 where the unstretched film travelling into the gap 4 leaves the feed roll 1 and the line 6 where the stretched film first contacts the roll 2. The lines 5 and 6 extend in a direction normal to the plane of the drawing. In an embodiment of the process of the invention using the above apparatus an unstretched film web consisting of the polycarbonate of 4,4- dihydroxydiphenyl-2,2-propane, the film in the unstretched state having a softening temperature of about 150‹ C., is delivered on to the feed roll 1 which is maintained at a surface temperature of about 130‹ C. The polycarbonate film travels through the gap 4 and passes over the draw roll 2 the surface temperature of which is maintained at about 210‹ C., i.e. well below the softening point of the stretched film which is about 240‹ C. The film in travelling through the stretching zone between the lines 5 and 6 is raised in temperature to the required stretching temperature of about 180‹ C. by the layer of hot air 7 carried into the gap 4.

Title: Purification of aromatic acids
IPC: C08G63/181
Filed: 1961-12-14
Abstract: Aromatic acids, prepared by the known process of oxidising a lower alkyl aromatic compound in the presence of water and an oxidant comprising an inorganic sulphur compound containing sulphur in a reducible state to obtain a crude oxidation product, converting any acid values not already in the form of an alkali or alkalineearth metal salt to a solution of said salt, and thereafter acidifying the salt with a mineral acid to obtain the corresponding acid, are rendered free of coloured or colour-forming impurities by treating the salt solution, prepared as above, with an aqueous solution of hypochlorite ion in an amount of 1 to 20 mol per cent based on the acid values present in the mixture at a pH of 6 to 12 and a temperature from 50 to 90 DEG C. for 5 minutes to 6 hours prior to the acidification. The term "lower alkyl aromatic compound" is defined as an aromatic compound substituted with one or more alkyl groups, other than tertiary, containing from 1 to 6 carbon atoms. Lower alkyl aromatic compounds specified are lower alkyl benzenes, e.g. the xylenes and toluene, lower alkyl naphthalenes, and lower alkyl aromatic compounds having substituents other than the lower alkyl groups themselves, e.g. a carboxyl group.  The hypochlorite ion may be in the form of a water solution of an alkali or alkaline-earth metal hypochlorite, or may be generated in solution by passing chlorine through a basic aqueous solution of the crude acid solution having a pH of 7 to 11. The aromatic acid may be further purified by contacting the acid salt after the hypochlorite treatment with another oxidising agent selected from manganese compounds containing manganese at an oxidation state above +2, chromium compounds containing chromium at an oxidation state above +3 and peroxides, or by treatment with a decolourising agent, e.g. activated charcoal.

A method of controlling the operation of an electrically controlled pressure die-casting machine by the weight of a casting released from the mould consists in restricting movement of a pivoted weighing surface until cessation of oscillation due to a casting falling thereon, and then allowing the surface to deflect so that if the casting has its predetermined weight the surface tilts far enough to close a switch in an operation-controlling circuit and causes discharge of the casting thereon to permit the surface to return to its normal position where it actuates a further switch, the non-actuation of the first switch stopping the machine operation, with or without a signal that the machine is inoperative. The weighing apparatus includes a scale pan 5 on to which the casting is ejected. If the weight of the casting is as prescribed the scale beam 1 tilts, the mould closing movement is permitted and the casting is removed from the pan 5 by engagement of the pan supporting lever 6 with a stop 8, the casting falling on to a shoot 9.
