Abstract: 1404895 Discharging static electricity W SPENGLER 3 April 1973 [15 June 1972] 15878/73 Heading H1X In equipment for discharging an electrostatic potential from a surface of a material that is a poor conductor of electricity by passing the material through an electric corona discharge generated between a pair of electrodes extending between lateral bearing members 2<SP>1</SP> and 2, one electrode of the pair is a rigid conductor 4 having discrete discharge points 3 spaced therealong which is rigidly fixed to at least one of the bearing members, and the other electrode of the pair is a conductor 5 supported between the bearing members by resilient means 6 allowing relative movement between the conductor and at least one of the bearing members to ensure the maintenance of a substantially constant distance between the electrodes of the pair and between the electrode 5 and the surface of the material to be treated. To prevent distortion due to expansion of the electrodes 4 in the frame structure formed by the bearing members 2<SP>1</SP>, 2 and a connecting plate 1<SP>1</SP>, the electrodes 4 are fixed to the frame structure at one end only. The plate 1<SP>1</SP> may be omitted, in which case the electrodes 5 are defined by lengths of a single conductor formed in a succession of hair pins, and having an insulating coating which is protected by insulating sleeves 9 where the conductor passes through the bearing members 2<SP>1</SP> and 2. Alternatively the electrodes 5 may be separate conductors surface insulated in the zones confrotinng the electrodes 4. The conductor 5 is tensioned by compression springs 6 bearing on washers 7 and retainers 8 fixed to the conductor. Alternative cylindrical cage embodiments are described (Figs. 3 to 6, not shown) having the discharge points projecting inwardly for treating a cylinder or outwardly for treating a tube to act as a stationary or slowly moving deflecting device for a travelling web.

Title: Improvements relating to centrifugal separating machines
IPC: B04B1/08
Filed: 1939-05-30
Abstract: 529,348. Centrifugal separators. RAMESOHL & SCHMIDT AKT.-GES. May 30, 1939, No. 15904. Convention date, July 11, 1938. [Class 23] A centrifugal separator, particularly for the separation of cream from milk, has a sealed connection between the inlet pipe and the drum. An annular chamber 11 is disposed about the meeting place of the fixed inlet pipe 1 with the rotating inlet pipe 2. An annular member 12 projects into this chamber ; it is attached to the rotating pipe 2 and has a conical form ; it carries ribs or blades 14 facing an air gap 15a. The under-side of the top wall of the chamber 11 carries blades 13 opposite the gap 15 between the inlet pipes 1, 2. The entering liquid passes from the pipe 2 to the bowl from which the skim milk flows by the channels 4 and collector 6 to the outlet 7. The cream passes through the central chambers 8, 9 to the outlets 10 and the collector 17. When the supply valve is opened some of the entering liquid passes through the gap 15 and fills the chamber 11. The excess pressure produced by the ribs 14 over that produced by the ribs 13 on the liquid in the chamber 11 maintains a liquid seal across the gap between the feed pipes 1, 2. In the case of low pressure working one set of ribs suffices. Leakage liquid is collected by the chamber 16 and passed to the collector 17. The separating groove 18 between the pipe 2 and the bowl terminates in the chamber 19 which passes any escaping fluid by the channel 20 to the collector 17. De-aeration is effected by the channel 21 or by the pipe 22; a stop-cock 24 with ports of different sizes is fitted in the pipe 22 to prevent the outflow of liquid. In a modification the member 12 is stationary and the walls of the chamber 11 rotate. The inlet may be arranged at the bottom of the bowl, and the sealing device may be placed inside the drum. The inlet and outlet may be disposed axially one above the other.

Patent GB-361820-A (GB)
Title: Manufacture of aqueous solutions of silk fibroin
IPC: D01F4/00
Filed: 1931-06-02
Abstract: The process of the parent Specification is modified by avoiding high concentration of ammonia when the silk fibroin solution in liquid ammonia is diluted with water.  The rapid elimination of ammonia may be effected by bringing the anhydrous ammonia solution of fibroin on to the surface of the water in the form of a fine spray and removing, at the same time, the excess of ammonia by a strong air current directed on to the surface of the water, or by causing the liquids to act on each other in a sprayed condition, also while using a current of air.  The elimination of ammonia may be further assisted by strongly stirring the mixture and heating it.  After the mixture is complete, the residual ammonia may be eliminated in a vacuum.  In an example, raw silk waste, cocoons, or other material containing silk fibroin is degummed by boiling with soap solution and is then treated with hot dilute acetic or other weak acid.  The dried silk fibroin is dissolved in liquid ammonia at a temperature of -75 DEG  C.  The solution is filtered and then sucked through a pipe into a deep container connected with a vacuum pump.  The solution enters below the surface of a quantity of water in the container.  The mixture which is under high vacuum is continuously stirred, and the temperature is kept at 5-10 DEG  C. by a hot-water jacket, and by regulating the introduction of the cold ammoniacal solution.  In order to avoid formation of foam, a small quantity of octyl alcohol is added.  After all the fibroin solution has been added to the water, stirring is continued and the temperature may be raised to 20 DEG  C.
