Patent GB-218034-A (GB)
Title: Improvements in the manufacture of phenol and phenolic bodies
IPC: C07C37/04
Filed: 1923-04-12
Abstract: In the manufacture of phenol or its homologues by fusing the corresponding sulphonate with caustic alkali, the fusion is effected with exclusion of air, at temperatures above 300 DEG  C., and with only a small excess of caustic alkali, say 2.2 molecules per molecule of sulphonate.  The air may be excluded by working in an atmosphere of nitrogen or hydrogen, or by completely filling a container with the mixture and closing it tightly, or by partly filling a rotary drum, provided with a small outlet for steam, with the mixture and heating it in an oven; the escaping steam expels the air, and when cooling the outlet is closed to prevent entry of air.  The reaction product may be worked up by extracting it with an amount of water insufficient to dissolve the sodium sulphite; the latter is filtered off and dried and used for converting benzenesulphonic acid into its sodium salt, the sulphur dioxide evolved being used for decomposing the extracted sodium phenate.

Title: Improvements in the manufacture of porous articles from polymeric resins
IPC: F25D23/08
Filed: 1955-04-07
Abstract: Porous shaped articles are produced from a polymeric resin by introducing into an enclosing mould a finely divided resin containing a volatile organic solvent having a boiling point lower than the softening point of the resin and heating to above the softening point to expand the resin and fill the mould which permits the escape of gases, but retains the resin, the solvent-containing resin being obtained by incomplete evaporation of the solvent from the solvent-resin solution. Specified resins are chlorinated polystyrene and poly-N-vinyl carbazole, preferably having a k-value of at least 30.  Specified solvents are benzene, toluene, p-xylene, methylene chloride and cyclononane for the carbazole and methylene chloride, chloroform, carbon tetrafluoride and ethylene chloride for the chlorinated polystyrene.  Pre-expanded particles of a solvent-containing resin may be used.  The process details are the same as those described in the parent Specification.

A pivoted knuckle coupler 3 mounts a transitional coupling 2 comprising a member 18 pivoted on a pin 19 beneath the coupler head, so that the coupling 2 may be brought to an operative position with a hook 6 by manually swinging the member 18 up into the throat of the coupler 3, the member 18 being held in the throat by rotation of a lock operating rotor 11 to hold the knuckle 14 closed. The member 18, which has an adjustable screw and nut connection for engagement with the hook 6, is provided with a depending ear 40 bearing a pivot 39 supporting a gravity swing latch 38, so that in the hook engaging position the end 41 of the latch prevents the rotor 11 from swinging fully upwardly to accidentally unlock the knuckle of the coupler 3. In the inoperative position of the hook coupling 2 the screw 25 is swung down and abuts the other limb 43 of the latch 38 and causes the latch to pivot out of the way of the rotor 11.

Straps 14, 15 for attachment to the legs of an airman are provided respectively with buckles 12, 13 through which passes freely a strap 7 secured at one end to the aircraft. by a pin and bracket connection 3, 4 and a forked fitting 5 which holds releasably a roller 6 to which strap 7 is secured, the roller being capable of withdrawal from fitting 5 upon application of a predetermined tension. Strap 7 is then passed through a snubbing box 10, arranged so that the strap may be drawn through the box downwardly but not upwardly, and it then passes through buckles 12 and 13 to a releasable fastening 20, 21 (see Group XXV). Upon ejection of the seat, strap 7 is drawn through snubbing box 10 by the connection to the aircraft and thereafter roller 6 is sprung out of fitting 5, the tensioned strap 7 and straps 14, 15 holding the airman's legs firmly against the seat. When the airman leaves the seat, automatically or voluntarily, the fastening 20, 21 is released by mechanism associated with release devices for the seat harness of the kind described in Specification 854,769. Two straps 7 may be used, one for each leg, each with a releasable fastening 20, 21. Specifications 583,257, 685,125, 711,234 and 761,508 also are referred to.

[Class 40 (ii)] In a magazine gramophone a pause mechanism for producing a time delay between playing of successive records consists of a smooth rod 1 moved step-by-step against a spring 2 by a driving member 7, which is oscillated by a continuously revolving eccentric cam 8, and grasps the rod 1 by mutually opposing edges at a certain angular displacement, the return of the rod 1 being prevented during the feeding process by a similar member 13, until the rod 1 trips a lever 25, whereby a clutch 22 couples the driving shaft 12 via pinions 20 and 19 to a pick-up control member 18. During playing of a record the curved part 16 of the member 18 supports the end 15 of the member 13, which is thereby rendered inoperative so that no feeding action of the rod 1 takes place. The amount of time delay may be preset by an eccentric disc 3, and the amount of movement of the rod 1 during each revolution of the eccentric cam 8 may be adjusted by means of the screw 5.
