Title: Arc Incandescent Lamp for Therapeutic and other purposes.
Inventor: GIMINGHAM EDWARD ALFRED
IPC: A61N5/06
Filed: 1916-07-26
Abstract: 104,350. Gimingham, E. A. July 26, 1916. Arc lamps for curative purposes and for sterilizing liquids or solids comprise tungsten or like electrodes in silica bulbs which contain nitrogen or other inert gas and can easily be opened for cleaning and for replacing the electrodes. In one arrangement, the bulb is made with a wide flange c, Fig. 1, which can be ground off. The leading- in wires, which are steadied by a silica frame i, Fig. 4, may he bent back at their ends to form eyes for the ends of the electrode stems and of a filament f, and are bound by clips j. Before insertion in the eyes, the ends of the electrode stems may be wound with a single layer of wire. Initially, the filament f is heated by current, and an are is established between it and the ball electrode e ; the arc may be transferred from the filament to a larger electrode d. The bulb may be spherical or may be tubular and of small diameter, to allow of insertion in the cavities of the body. A cylindrical bulb to be placed in a vessel of liquid may be fitted at its upper end in a sheath serving as a handle; in this lamp, the filament acts permanently as an electrode. Liquid to be sterilized may also be passed through a tube near the arc. A tubular bulb provided with a water jacket may have a wide mouth sealed by insulating-cement within a handle, from which it may be removed after unscrewing a ring placed between the bulb and handle. Specifications 2323/14 and 22437/14 are referred to.

Patent GB-672972-A (GB)
Title: Process for the recovery of protein from protein-containing material
Filed: 1949-01-21
Abstract: Artificially coagulated protein is recovered from a protein-bearing liquid in which at least a part of the protein is dissolved by the addition of solvent means, e.g. an alkali or acid-containing liquid, and undissolved substances are at least partly removed and the protein is precipitated in separable form by the addition of a precipitating agent, e.g. sulphuric acid, and sulphur dioxide, the protein-bearing liquid being, after the protein precipitation, concentrated in a centrifugal separator and the sludge thereby separated out is, whilst adding liquid, subjected to a further centrifugal separation in one or several stages for washing-out impurities contained in the sludge, and the whole quantity of the liquid component discharged from the separator at the first washing operation, or part of this quantity, is reintroduced into the process before that place where the dissolving means is added.  In modifications the liquid component discharged from the separator in the first washing is used, prior to being returned, for leaching the sludge separated at the filtration of the liquid containing dissolved proteins and the liquid obtained as a result of initial protein concentration is completely or in part removed from the process.  In an illustration ground protein is mixed with the dissolving liquid, the pH adjusted to above 7, solid removed, protein is precipitated from the liquid residue with sulphuric acid and concentrated in a centrifugal separator before washing with, e.g., pure water, and the wash liquid obtained on reconcentration is returned for use as dissolving liquid, optionally together with fluid from the concentration.  Other illustrations show a two-stage washing-out system, a system in which the filtrate from the first separator is again centrifuged and in which recovered wash liquid is used to leach out the residue from the first separator and a two-stage system for leaching out residue from the first separator.  In the last two cases the pH of the returned leaching liquid is adjusted to be equal to that of the protein-bearing liquid initially filtered.  Specification 670,261, [Group I], is referred to.
