Title: Improvements in or relating to resins prepared from steam-cracked petroleum fractions
IPC: C08F240/00
Filed: 1953-07-24
Abstract: Resins are prepared by polymerizing at a temperature between -10 DEG and 70 DEG  C. in the presence of an aluminium halide catalyst a steam-cracked petroleum fraction boiling between 85 DEG  and 275 DEG C. (\sB10 DEG  C.), in which not more than 20 per cent boils below 130 DEG  C.  The fraction contains 10 to 20 per cent of diolefins and 20 to 60 per cent of cyclic and acyclic olefins.  The catalyst may be aluminium chloride in solid form, in solution in methyl or ethyl chloride or as a slurry in hexane or a solution of aluminium bromide in a hydrocarbon.  The catalyst is removed from the reaction mixture by settling out the sludge, washing with water and/or caustic or by precipitating with methanol and filtering. The resin solution is then purified by stripping off unreacted hydrocarbons and oily polymers, preferably followed by vacuum stripping to a bottoms temperature of 200 DEG  to 300 DEG  C. at 2 to 10 mm. Hg. or by steam stripping. The products have softening points between 90 DEG  and 120 DEG  C. and Wijs iodine numbers between 60 and 100.  They may be used in floor tile and rubber compositions.

[Also in Group XXIII] The tool-carrier 102 of a reciprocatory hand tool for filing, grinding, and like operations is reciprocated in a cylinder 103 by a crank mechanism 108 to which it is connected by a rod 107 and a hemispherical member 109 that allows free angular movement of the carrier about its own axis. A sleeve 115, which is rotatable on the cylinder 103 but is prevented from moving axially by a flange 117, is provided with a slot 106 which guides the tool reciprocations by the engagement in it of a boss 101 for a tool-clamping screw 104. A split collar 118 has a pair of handles 121 and 122, one of which serves as a clamping screw, and can be clamped on the sleeve 115, either in the rear position, as shown, in which a pin 123 on the casing engages a slot 124 in the collar and so locks the sleeve and tool-carrier in fixed angular position, or at a point along the sleeve within convenient reach of the operator's forefinger and middle finger so that he can vary the angular adjustment as required. If the clamping screw 121 is released, the tool-carrier is free to adjust itself about its own axis, according to the working plane. A spring 110 is fitted between the tool-carrier and a plunger 111 bearing on the conical end of the connecting-rod 112 and allows the tool to retract if undue resistance is encountered.

Filed: 1971-04-19
Abstract: 1333499 Temperature measurement; pH sensors PROTON A G 19 April 1971 [14 Dec 1970]  20798/71 Headings G1D and G1N A retractable sensor probe 7 for measuring a parameter such as the pH value, temperature, pressure or fluid level in a vessel 3 without affecting conditions in the vessel (i.e. releasing the pressure, lowering the temperature etc.) is slidably mounted in a guide member 6 fixed to the vessel and separated therefrom by a ball valve 5, the probe being slidable only when the valve 5 is open between an inoperative position as in Fig. 1 and a position in which the probe tip 8 projects through the valve into the vessel, co-operating box nuts 22, 23 locking the probe in this latter position. Superheated steam may be circulated through chamber 25 between inlet 26 and outlet 27 to sterilize the probe before insertion, and fluid (e.g. hydraulic oil) under pressure may be fed through inlet 29 behind a stop flange 21 to force the probe into the vessel if its contents are at high pressure. A safety arrangement consisting of a rotatable slotted disc member 30 and coupling rod 32, linked for movement with the valve handle 31, limits movement of a rod 34, rigidly connected to the probe, and thereby prevents the probe being pushed forward and damaged before the valve is opened and prevents the valve from being closed before the probe has been withdrawn. Unscrewing of the nut 22 from the member 6 allows withdrawal of the probe from the member 6, a movement which is prevented when the valve is open by a bar 36, coupled to handle 31, engaging stop 35.
