Filed: 1920-03-22
Abstract: 164,543. Joseph, G. F., and Cobbold, H. N. H. March 22, 1920. No Patent granted (Sealing fee not paid). Soldering-irons.-In an electrically heated soldering-iron, the heating-wire is wound on the reduced stem of the bit between the bit and an enlargement on the stem, which receives an insulator block carrying metal connections for the end of the wires and the main conductors, which pass through a handle tube secured to the bit by a cover tube. The enlargement 3 on the stem 2 is slotted to receive a porcelain or like insulator block 5 which is bored to receive tubular metal connections 9 in which the ends of the wire 10 and conductors 11, 11<x> are secured by screws 12. The conduclors pass through the handle tube 14, which is mounted in a flanged collar 15, held in a cover tube 16 screwed to the bit, by a screwed clamping-collar 18. Relative rotation between the collar 15 and enlargement 3 is prevented by dowel pins 17. The handle tube is secured in an insulating hollow handle which is provided with a removable end cap. The main conductors are secured to terminals at the end of the handle inside the cap, and the main leads pass through the end of the cap and are secured to the terminals. The heating-wire is coiled on a mica or other insulation 23 shellaced on the stem, and the return layer of wire is separated from the first layer by two sheets of mica or micanite 24 breaking joint. Sheets of mica or other insulating material are then bound thereon by wires &c., which are surrounded by asbestos sheets secured by bands of wire &c. The spaces behind the connections 9 are packed with asbestos sheet and wool.

Abstract: 140,771. Vallino, L. March 20, 1919, [Convention date]. Trolly heads and pulleys; devices for retaining collectors; controlling arrangements for collectors; conductors for electricity. - Two elevated conductors 10 are engaged by a collector comprising an H-shaped frame 0, Fig. 1, of insulating-material, having four tubular casings 1 which support tubes 2 carrying pins 3 for the wheels 4, which are in the same plane as the conductors. The wheels engaging one conductor are connected together and to one wire of the supply lead 13. The connecting-lead 12 is secured to the casings 1 or to brushes fixed to the pins 3 and engaging the wheels 4. The pins S slide in grooves 5 in the casings 1, and opposite pins are pressed either apart or together by springs 6. Guards 19, Fig. 2, are carried by the pins 3 to prevent displacement of the wheels, should the springs break, and in winter the guards may be replaced by elastic blades to sweep away snow and ice. At the supports, Fig. 5, each conductor is split into two branches 10' which are fixed to a clamp 15 having a stem 15' passing through either an insulator 16 and a wooden &c. arm 17 on the pole 14, or a stirrup 21, Fig. 6, secured to the arm 17. To prevent the lead 13 engaging the wheels 4, and also to prevent short-circuiting between the wheels due to jets of water, the frame 0 is provided with projections 20 of insulating- material. The grooves in the wheels 4, Fig. 2, are concave, and the shoulders differ in size.
Patent GB-766628-A (GB)
Title: New glucoside
IPC: C07H17/04
Filed: 1955-03-23
Abstract: The invention comprises a new glucoside ("ipecoside") extracted from ipecac, and its dimethyl, dimethyl-tetracetyl, and hexacetyl derivatives.  The ipecac is first extracted with a solvent for ipecoside, e.g. water or an alcohol of 6 or less carbon atoms or a mixture thereof with a halogenated aliphatic hydrocarbon.  The alkaloids and fatty matter are then removed from the extract by means of an organic solvent therefor, e.g. ether, chloroform, trichlorethylene and tetrachlorethane, preferably after concentrating the solution.  The ipecoside is recovered from the residue by filtering in the presence of a decolorizing agent, evaporating to dryness and recrystallizing from an aliphatic alcohol of 6 or less carbon atoms.  Ipecoside has the formula C27H35O12N and gives glucose and an aglucone on acid hydrolysis.  Examples show the extraction of ipecoside from ipecac, and the preparation of (1) the dimethyl derivative using diazomethane; (2) the tetracetyl derivative of (1); and (3) hexacetyl-ipecoside.  It is stated that ipecoside may be acylated with other organic acids, e.g. salicylic, acetylsalicylic, 2 : 3 : 5-trihydroxybenzoic or 2 : 3 : 5-triacetoxybenzoic.

The ends of the assembly are bonded to flanged thermo-plastic discs (one not shown), by bringing the respective disc and end into contact under slight pressure in the operative region of an induction coil and passing current through the coil, whereupon the metal-covered ends are heated, and upon application of further pressure become embedded in the discs. The strip 6 alternatively may be located on the outside only, or on the inside only, or both, or on the extreme edge only, or on the edge and one side, or it may be embedded at the edge within the thickness of the filter material. The metallic coating alternatively may be applied by spraying.
