Title: Method of treatment of the higher phenols for germicidal purposes
IPC: A61K31/05
Filed: 1927-07-29
Abstract: 299,522. Leonard, V. July 29, 1927. Antiseptics; lotions; medicines for internal use. -An effective bactericidal solution of normal hexyl resorcinol, for sterilizing living tissue surfaces or objects such as surgical and dental instruments or false teeth, is prepared by dissolving the hexyl resorcinol in glycerol and adding water to obtain a clear solution having a very low surface tension. There is an optimum composition of glycerol and water at which the surface tension reaches a minimum value and the germicidal power reaches a maximum. Further addition of water does not precipitate the hexyl resorcinol and only raises the surface tension relatively slightly. As an example, one part of hexyl resorcinol is dissolved in 300 parts by weight of glycerol .and 700 parts of water are added. The clear solution obtained has a surface tension of 3'7 dynes per centimetre. Reference is made in the Specification to the known use of a solution of hexyl resorcinol in olive oil for internal administration. Specifications 9726/94 and 15931/08 are referred to. The Provisional Specification describes the application of the process to such of the higher phenols (such as hexyl resorcinol and its homologues) as are soluble in glycerol, or to mixtures of these higher phenols.

Title: Improvements in or relating to shoe upper trimming machines
IPC: A43D49/00
Filed: 1924-08-27
Abstract: 243,436. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Aug. 27, 1924. Trimming.-A rotary-cutter trimming-machine for trimming off the excess lining fabric projecting beyond the margin of a closed shoe upper, particularly the upper of a rubber boot or overshoe, is provided with improved means for feeding away the trimmedoff material and for presenting the work to the cutters, and with improved cutting and cutter guarding devices. Mounted in an arm 8 of the machine are two shafts 9, 11. A cutter 13, Fig. 2, in the form of a thin flexible steel disc is secured by a screw 25 to the shaft 9, which is connected to the shaft 27 of a motor 29. A cooperating shear member 15 with a frustro-conical work-support 17 is secured to the shaft 11, which is set at a slight angle to the shaft 9 and is connected by a universal joint to a shaft 111 driven by gears 33, 35 from the shaft 9. In order slightly to flex the cutter 13 against the member 15 the shaft 9 is urged to the right, in Fig. 1, by a spring 37 to an extent limited by an adjustable collar 41. Means for feeding away the trimmedoff lining material 200 comprise a grooved member 57, Fig. 2, mounted in rear of the member 15 and a cooperating member 63 which is mounted on the shaft 9 in rear of the cutter 13. The opening 81 in the roll 63 is of greater diameter than the shaft 9, and the roll 63 is retained in place on the one side by a washer 65 and on the other side by a spring-pressed member 77. This mounting allows the roll 63 a floating movement on the shaft 9 against the friction due to the member 77, causing the material 200 to be gripped yieldingly by the feed members. Means for guiding the work to the cutters without damage tq the upper material includes a guard 87, Fig. 3, adjustable horizontally and vertically of the cutter 15 and a guard 83, adjustable lengthwise of the shaft 9, for the cutter 13. The guard 83 has a segmental rib 95 slidable in a guideway in its holder 86 so that the guard 83 may be swung in a clockwise direction by a hand-lever 107, to an extent limited by stops, in order to increase the gap between the two guards for the passage of any thickened portion, for example a seam, on the lining material. The shape of the work-support 17 causes the work to be presented at an inclination to the cutters so that the lining is trimmed somewhat inside the margin of the upper. For work on boots the work-support shown in Fig. 6 may be attached to the arm 8 by means of the bracket 121. The support comprises a roll 139 on a rod 137 adjustable in a tube 133 pivoted to the bracket 121, the pivot lying vertically below the overlapping portions of the cutters. Lubricant is supplied to the cutter 13 from a cup 141 by means of a duct 143 and grooves 143<*>, Fig. 3.
