Patent GB-170060-A (GB)
Title: Manufacture of transparent soap
IPC: C11D15/00
Filed: 1920-07-02
Abstract: A transparent soap is made by saponifying a mixture of fats and resin.  According to one process, a mixture of coco-nut oil, cotton-seed, castor or other vegetable oil, edible tallow, and water-white resin is melted at 55 DEG  C., an alcoholic solution of caustic soda and potash added, and the whole heated to 80 DEG  C. for eight hours and allowed to stand for about fourteen hours.  If the soap is not quite transparent, hydrogen peroxide is added and stirred in at 60 DEG  C. and the alcohol then distilled off at 90 DEG  C. If the soap is transparent after standing, the alcohol is distilled off first and the hydrogen peroxide added afterwards. For harder soap other formulae are given in which Russian tallow replaces the edible tallow.  In this case the oils, fats, and resin are heated to 75 DEG C. and the alkali introduced in aqueous solution.  The mixture is heated to 80 DEG  C. for three hours. Alcohol is then added and the mixture heated to 80 DEG  for eighteen hours, being repeatedly stirred.  The mixture is then heated to 84 DEG  C. for six hours.  If a soap of a portwine colour is desired the soap is immediately filtered at 75 DEG  C., perfume being added if desired.  For an amber-coloured soap, hydrogen peroxide is added to the soap before filtering and the mixture heated to 65 DEG  for an hour and then filtered.  Apparatus such as described in Specification 170,781 may be used for stirring and filtering the soap, a linen cloth being used in the filter.

Abstract: 750,329. Davit gear. MAREPA TRUST, Ltd. July 5, 1954 [July 3, 1953 ; May 25, 1954; June 12, 1954], Nos. 18439/53, 15326/54 and 17333/54. Class 115. [Also in Group XXX] In a launching gear for a ship's lifeboat including two davits with associated wires or ropes for manipulation of the davit arms, a compensating device is provided whereby one or other of said wires or ropes can be wound or brought in further, even although its davit arm is in the fully inboard position, without being subjected to undue strain. In Fig. 2 the device comprises a bottle screw 16 to which the standing parts of the fall ropes 12, 13 of the two davits are connected. Plates 17 on the screw bear against buffers 18 slidable in brackets 19 fixed on a member 20 extending between the two davit frames (not shown). If one davit arm is brought fully inboard before the other, one or other of the sleeves 18 will slide against the force of the spring 21, this in effect drawing in the standing part of the lagging arm and paying out that of the other so that the lagging arm can be brought fully inboard by a further operation of the winch on which both fall ropes are wound without putting undue strain on the fall rope connected to the other arm. In Fig. 4 the device comprises a bracket 26 mounted on the ship's structures and having pivoted thereto a lever 27 to which the standing parts of the fall ropes 22, 23 are connected. If one arm arrives fully inboard before the other, the lever will tilt about its pivot to take up on the standing part of the lagging davit and pay out on the standing part of the other davit. To balance an uneven load, e.g. when raising a lifeboat with an engine aft, one arm of the lever may be longer than the other. In Fig. 6, the fall ropes 33 are led to the winch 34 via the device, i.e. over pulleys 36 on a lever 37 pivoted in a bracket 38 mounted on the ship's structure. The lever is free to swing so that more or less even tension is maintained in both fall ropes until both davit arms are in their fully inboard position.
