Filed: 1926-07-07
Abstract: 273,896. Dunlop Rubber Co., Ltd., Truesdale, R., Smith, R. C., and Simpson, E. July 7. 1926. Machines for making. - In apparatus for making cords or strings suitable for substitutes for catgut and comprising a number of supply bobbins 2 carrying threads of silk, ramie, cotton, wool, &c. mounted on a rotating creel 3, an impregnating chamber 8, adapted to contain a viscous solution of cellulose or a solution of rubber, guttapercha or balata, and a twisting device for laying the threads into the cord or string, a vulcanizing chamber 16 is provided. Alternatively, a coagulating chamber and a drying chamber are provided. The vulcanizing chamber 16 may comprise a length of tubing heated either by maintaining a current of hot air therethrough or by enclosing the tubing in a spiral steam pipe or within a jacket; when a cellulose solution requiring coagulation is used, the chamber 16 may form the drying chamber. The coagulating chamber preferably has a pulley or pulleys arranged therein, around which the impregnated and twisted cord may be led. The twisting device is preferably arranged within the impregnating chamber 8 and comprises a guide-plate 9, Fig. 4, with slots 9<a> arranged circumferentially therein and having a conical extension 9b. The twisted threads pass out from the chamber 8 through a die 13, preferably of glass, which coats the cord with a thin film of solution. A coating chamber 14 wherein the cord may be coated to any desired thickness may be provided between the twisting device and the vulcanizing or coagulating chamber, a compacting and a smoothing die 15 being provided at its entrance and exit. The threads leaving the bobbins 2 may be tensioned by passing them through holes in a flange 5<a> on the upper frame 5 of the creel 3 or by passing them through loops 4<a> 4<b>, 4<c>, Fig. 6, arranged on the flange frame 5, this arrangement being specially adapted for cords wherein one thread is of different colour to the remainder, the coloured thread passing through two only of the loops and having less tension than the others, so tending always to twist to the surface of the cords. Alternatively, the threads may be tensioned by passing them between rollers held together by springs. The apparatus may be modified for making cords having cores formed in similar manner, an additional creel, impregnating chamber, twisting device and coating chamber being provided for forming the core.

Patent GB-978073-A (GB)
Title: Automatically operating sphygmomanometer
IPC: A61B5/022
Filed: 1963-04-30
Abstract: 978,073. Sphygmomanometers. SIEMENS-REINIGER-WERKE A.G. April 30, 1963 [May 5, 1962 (2)], No. 17034/63. Heading A5K. An automatically operating sphygmomanometer having means for increasing the pressure in a cuff above systolic pressure, after determination of the diastolic pressure, has control means for exhausting the cuff if no diastolic reading has been obtained and / or further control means for exhausting the cuff if no systolic pressure is recorded. Functioning of the equipment is controlled by a unit 11, initially switched on by a control button 12. This closes a switch 18 to energise a motor 19 which drives a compressor 20 and so, through a pressure accumulator 21, inflates a cuff 2 on the patient's arm 1. A microphone 3, receiving pulse sounds from the artery, passes its output through amplifiers 4, 6 to a pulse generator 8 which controls the circuit 11. The cuff pressure rises gradually until a pulse is detected at the diastolic pressure, whereupon a valve 13 is closed to record this pressure on a gauge 28. The pressure then continues to rise to a point above systolic, where the pump is switched off and the pressure is allowed to leak off slowly through a valve 35. When the pulse is subsequently detected, at systolic pressure, a further value 14 is closed to record the pressure on a second gauge 29. Both gauges may be connected to remote reading instruments. If the pressure rises above a predetermined point without a diastolic pressure having been recorded, a pressure-sensitive valve 24 releases a contact 26 to open a rapid discharge valve 17, which exhausts the conduit 23 to atmosphere. During normal use, however, this is overridden by a parallel switch 15 which is closed when the valve 13 is closed. A similar pressureresponsive valve 25, operating in the reverse direction, opens its contact to release the rapid discharge valve 17 if the pressure, during the decreasing portion of the cycle, falls below a predetermined minimum without a pulse having being detected at the systolic pressure. Again, under normal working conditions, it is overridden by a parallel switch 16 when the systolic pressure is recorded. Specification 792,875 is referred to.

Title: The photographic manufacture of master plates for offset printing
IPC: G03F7/016
Filed: 1959-05-20
Abstract: 867,264. Photolithographic printing plate production. GENERAL ANILINE & FILM CORPORATION. May 20, 1959 [June 9,1958], No. 17168/59. Class 98(2) An original is exposed in contact with a base having a surface of a water-soluble diazocontaining polymer to render exposed portions insoluble, such surface is contacted with the wet surface of a hydrophilic colloid on a second base and then removed, to leave the remaining, soluble portions of the exposed surface on the second base, and such soluble portions are decomposed whereby the hydrophilic colloid in contact therewith is tanned and becomes inkaccepting. The process may be effected in approximately 30 seconds. In an example a paper base calendered with insolubilised casein is coated with a dope comprising polyvinyl methyl ether maleic anhydride and cellulose :acetate, sensitised with p-diazo diphenyl amineformaldehyde condensation product, exposed in contact with a typewritten image on a translucent sheet of paper, and contacted with a similar calendered and doped paper but which bad been subjected to the action of hot moist ammonia fumes to render the surface hydrophilie and wetted with aqueous ethylene glycol; after which the so wetted paper is briefly reexposed and put on an offset press for printing. Other diazo compounds for use in the process are quoted with reference to foreign specifications, and gelatin, glue and water-soluble cellulose ether may be used as the hydrophilic colloid. The transferred diazo compound may be decomposed chemically or by heat instead of the re-exposure of the example.
