Patent GB-787231-A (GB)
Title: Stabilization of 3,4-dihydro-2-formyl-2h-pyran
IPC: C07D309/26
Filed: 1956-06-22
Abstract: The invention comprises an acrolein dimer (3,3 - dihydro - 2 - formyl - 2H - pyran) composition having improved stability on storage comprising substantially pure acrolein dimer and comminuted iron oxide intimately dispersed throughout the dimer. The iron oxides are ferrous oxide, ferrosoferric oxide, ferric oxide, iron rust, or any mixture of such oxides.  The iron oxide may be added in amounts of 0.01 to 5 per cent, preferably 0.1 to 2 per cent, based on the weight of acrolein dimer.  The dimer and oxides are thoroughly mixed before storage.  Pigment grade iron oxides having a particle size averaging less than 1 micron are particularly suitable, but stabilization can be obtained with particles whose size is not more than 0.833 mm. in diameter.  The stabilizer can be removed by filtration, distillation or centrifugation and in cases where the stabilizer will not interfere with the use of the dimer it is not necessary to remove it. Examples indicate the period of storage stability of various compositions at 25 DEG , 50 DEG  and 100 DEG  C., and a comparative composition using oxalic acid as stabilizer is also described. The iron oxide-stabilized acrolein dimer may be stored in glass containers, carbon steel drums, stainless steel drums, and metal drums lined or coated with epoxide resins, phenol-formaldehyde resins or amine modified phenol-formaldehyde resins.  The iron oxide-stabilized acrolein dimer when hydrolysed to 2-hydroxy adipaldehyde after storage in a glass container yields an easily filterable solution of the aldehyde containing less insoluble polymer than is found when no stabilizer is present, or when oxalic acid is used as a stabilizer.

Abstract: Phenols of formula <FORM:0787135/IV (b)/1> wherein X and Y are tertiary alkyl groups and R is an alkyl or substituted alkyl (e.g. benzyl) group are prepared by reacting a 3 : 5-di-tertiary-alkyl-4-hydroxy-benzaldehyde with hydrogen peroxide in the presence of an aqueous alkali metal hydroxide solution, but in the absence of air, to give the alkali metal derivative of a 2 : 6-di - tertiary - alkyl - hydroquinone and subsequently alkylating this alkali metal derivative or the corresponding free hydroquinone. Specified alkylating agents are alkyl halides and dialkyl sulphates. In the example, equimolar amounts of hydrogen peroxide and 3 : 5-di-tertiary - butyl - 4 - hydroxy - benzaldehyde were reacted in aqueous sodium hydroxide solution, in an atmosphere of nitrogen, to give 2 : 6-di-tertiary-butyl-hydroquinone on acidification with hydrochloric acid and the hydroquinone was reacted with dimethyl sulphate to give 2 : 6-di-tertiary-butyl-4-methoxy-phenol.

Spillage coke may be discharged from chamber 87 on to a conveyer 33, which also carries away the main charge after it has been reloaded on to the car 2 and discharged down a conventional ramp, Fig. 2 (not shown). In a modification, Fig. 3, the car 2 runs on to a turntable 91 from which it is pushed directly into the cooling chamber 4. The roof duct 56 is cranked and a flow-reversing cover 74 guides the gas into the coke. The car is held against the air duct 14 by a lever 89 operated by fluid cylinder 90. In a final modification, Fig. 4 (not shown), the coke container may be lifted off the car and pressed against a cooling chamber disposed above it by a system of fluid cylinder operated levers.

Abstract: 1,219,902. Shock absorbers. B.T.R. REINFORCED PLASTICS Ltd. 17 April, 1968 [29 April, 1967], No. 19851/67. Heading F2S. A shock absorber, e.g. for supporting heavy loads against shock during transport, includes an elastomeric (rubber or polyurethane) shockabsorbing member in combination with an hydraulic damper. The damper consists of two liquid-filled chambers 10, 13 interconnected by a constricted passage or neck 12, the chambers and the neck being bounded by a suitably shaped thin sheet 11 of elastically deformable material, the sheet not being thick enough to provide in itself a significant shock-absorbing effect. The shock-absorbing elastomeric material is constituted by the much thicker-walled members 1 and 5 surrounding the damper. When a force is applied to the plate 2, it deforms the elastomeric shock-absorbing member 1 and also transmits force through the member 5 to the damper, causing flow of liquid between its chambers 13 and 10 by way of the neck 12.

Abstract: 728,465. Winding and unwinding webs. FIRESTONE TIRE & RUBBER CO. Aug. 7, 1952 [Oct. 18, 1951], No. 19905/52. Class 100(1). [Also in Group XXXIV] An apparatus for winding and unwinding web material, such as tyre ply stock, comprises a housing including a pair of reels and a liner secured to the reels, an idler roller around which the liner passes while being unwound from one reel and rewound on another reel, a control device, responsive to the amount of liner rewound, for terminating the reel drive, a detector responsive to the absence of web material as it passes to the liner which controls the operation of the reel drive, and braking means associated with the reels for preventing overrunning thereof. As shown, a liner 24, Fig 1, has its ends secured to reels 21 and 22 within a housing 23, the liner being adapted to be unwound from the reel 21 and wound on the reel 22. While the liner is being wound on the reel 22, tyre ply material (not shown) is passed over a table 26 and wound up between the convolutions of the liner. The reel 22 is driven by a driving roll 70, Fig. 3, engaging a flange on the reel, the roll 70 being driven through a chain and sprocket 72 and a speed reducer 74 by a motor 73. The roll 70 is urged into contact with the flange by a spring. A roll 82 is mounted on a pivoted arm 83 and engages the roll wound on the reel 22, such that when the roll attains a predetermined size the motor 73 is stopped by the arm 83 operating a limit switch. A feeler gauge 86 in the table 26 causes actuation of a limit switch in the absence of tyre ply material. The reels 21 and 22 are prevented from overrunning by means of straps, not shown, passing around annular flanges on the reels. When the tyre ply material is to be fed to a tyre building drum 121, Fig. 10, a plurality of housings 23 each comprising reels 21 and 22 are mounted on a wheeled frame 120 having shelves 122. The reel 21 is driven counterclockwise by means (not shown) to rewind the liner material 24, while the tyre ply material 25 passes over a roll 64 and around rolls 128, 129, 131, the roll 129 being a floating roll which controls, by its position, the reeldriving means.
