Filed: 1946-01-17
Abstract: 606,724. Securing reeds to mouthpieces. KING INSTRUMENT CO., Ltd., and DAVIS, L. Jan. 17, 1946, No. 1601. [Class 88 (ii)] A ligature 6 for attaching a reed 9 to the flat portion or table 2 of the mouthpiece 3 is channel shaped having the ends 7 of its legs turned in to engage a groove 5 in the mouthpiece. The groove 5 makes a small angle with the table 2 and the turned-in edges 7 of the legs make an equal angle with the web of the ligature so that on moving the ligature towards the mouthpiece its web moves towards but remains parallel to the table, the reed 9 being thus secured between the web and the table 2. The web may be lined interiorly with a suitable gripping material or may be ridged longitudinally so as to make line contact with the reed, Fig. 2 (not shown), or contact may be made by a plate inside the channel loosely supported by pins from the web, Figs. 3 and 4 (not shown).

Patent GB-647884-A (GB)
Title: Improvements in or relating to the purification of glycerol solutions
IPC: C11D19/00
Filed: 1947-01-20
Abstract: Alcoholic glycerol solutions containing soaps and esters resulting from the alcoholysis of glycerides are purified by splitting the soaps into fatty acids and extracting the resulting fatty acids and the esters by means of a selective solvent therefor such as aliphatic hydrocarbons (e.g. gasoline) and halogenated aliphatic hydrocarbons (e.g. trichlorethylene and carbon tetrachloride).  The splitting of the soaps is preferably carried out by sulphuric acid.  In cases where the alcoholic glycerol solution contains such a high proportion of soaps or esters as to cause the solvent to lose its selectivity, a proportion of the alcohol is evaporated after the solution has been treated with acid so as to increase the glycerol-alcohol ratio, whereby some of the esters and fatty acids become insoluble and settle out, after which the remainder of the esters and fatty acids are extracted by selective solvents as before. Specifications 587,523, 587,530, 587,532 and 587,533 are referred to.

Title: Continuous ionization injector for low pressure gas dis charge device
IPC: H01J17/30
Filed: 1976-01-20
Abstract: 1476293 Cold cathode tubes; ion pumps; ionization manometers HUGHES AIRCRAFT CO 20 Jan 1976 [14 April 1975] 02149/76 Heading H1D In a low pressure gas discharge device, e.g. a crossed-field switch tube, comprising a cathode and anode, an igniter 50 mounted on the tube comprises a separate chamber communicating with the chamber of the device, containing a thin wire anode 58 and cathode 66 to ionize the gas in the igniter which in turn provides ions and electrons to initiate a discharge in the main device when appropriate conditions are established. In a crossed-field switch tube (Fig. 1, not shown) the gap between concentric cylindrical cathode and anode is chosen so that at the operating pressure of the gas (e.g. H 2 , D 2 , He) the Paschen relationship inhibits initiation of a discharge, although voltage is applied, until the discharge is switched on by forming an axial magnetic field from a coil to lengthen the electron paths. The main anode may be a hollow gas reservoir. To provide initial ionization to reduce mean delay and jitter in firing, ions and electrons are supplied by a low voltage discharge in igniter 50, between axial thin wire anode 58 and the cylindrical wall cathode 66, screened from magnetic field by Fe or by eddy currents in a high conductivity sleeve 52, e.g. of Cu. The discharge current also serves to monitor gas pressure; sputtering from walls 66 to the less bombarded ends 53, 55 acts as a sputterion pump for active gas species.

In an apparatus for winding electrical condenser coils strips of conducting and insulating material are collected together, cut and passed to a coil winding position around pins or rollers to form loops during winding corresponding to desired relative final lengths. In one embodiment, three insulating strips 1, 2, 3, a conducting strip K and three insulating strips 4, 5, 6 are fed in between two halves 7, 8 of a gripping mandrel after an initial rotation of which an arm 12 with guide rollers 13, 14, 15, 16 is swung to the position shown in Fig. 6. Two further arms 20, 22 then close around fixed rollers 17, 18 to the positions shown in Fig. 7, while the strips 1 to 6, inclusive, and a further conductive strip B are wound on to the split mandrel. When sufficient winding has been effected, clamps 32, 33 hold the strips while being severed by a pair of cutter blades 31. At the same time a cutter blade 35 severs the conductive strip B. The winding is then completed and removed from the mandrel. To effect another winding the clamps 32 are slid to the position 32<SP>1</SP>, Fig. 8, to smooth out the ends of the strips, and both the clamps 32, 33 are then, in clamping engagement with the strips, moved from the dotted positions to the full line positions so that the ends of the strips are placed in position for the next winding. A further embodiment is described in which all the strips, including the second conductive strip, are all fed into the winding together, and are severed by the same cutter.
