In a charged particle phase-bunching apparatus, e.g. the injection system of a linear accelerator 2 comprising electron gun 5 and cavity resonators 8, 10 and drift tubes 9, 11, highfrequency power is supplied to the cavity resonator 8 via a coaxial cable 26 which over a portion of its length is wound around the iron core of a high-voltage pulse transformer 19 so that a pulse voltage is impressed on the cavity resonator in order to reduce the velocity of the beam at the point P1 and hence the length of the drift tube 9; the high-frequency power source 33 is coupled through the coaxial cable to the grounded side of the pulse transformer. Secondary windings 15, 16, 17 of the pulse transformer 19 are connected to the gun heater 7 and focusing electrode 6 while anode 4 is connected to secondary winding 18 and pulse transformer 20. Heater power source 23 and bias voltage sources 24, 25 are provided as shown. The primary of pulse transformer 19 is connected to pulse modulator 36 and pulse transformer 20 to pulse modulator 35. Pulse modulators 35, 36 and pulse source 34 for the high-frequency power source 33 are connected to a trigger generator 37. The transformer on which the coaxial cable 26 is wound need not be common with the high-voltage pulse transformer for the electron gun. The invention is also applicable to multi-resonator klystrons and to resnatrons.

Abstract: 288,746. Noel, F. A. G., and Baily, E. W. Jan. 24, 1927. Density separators; discharging. - A purified liquid is discharged, without aeration, from a centrifugal machine by means of a stationary collecting device which enters the bowl; a difference of pressure between the inside and outside of the collector induces an inward and upward flow of the liquid to the discharge pipe. The bowl 2 has a cover 3 secured by a ring 4 and is fed by a central tube 5 from a reservoir 6. The supporting framework 8 has hooks 10 engaging the casing 9, and also carries at its upper end a conical plate 12 to which the member 13 is attached. This member has two dependent sleeves 15, 19; the space between the sleeves forms the annular discharge passage, and at its upper end forms an annular chamber 22 communicating with the outlet 27. The lower ends of the sleeves are flanged and a duct 18 is provided between the sleeve 15 and the centre tube 5. Baffles may be arranged in the annular opening between the flanges. As the liquid passes through the apparatus, its discharge is assisted by the higher pressure in the chamber 21 in the rapidly-rotating drum cover and by the lower pressure in the chamber 22 in the stationary member 13. The duct 18 permits the escape of separated air or of excess liquid. Either or both of the sleeves 15, 19 may be made axially adjustable for the purpose of varying the discharge.

Title: Improved manufacture of cellulose compounds
IPC: C08B11/12
Filed: 1920-01-22
Abstract: A cellulose compound suitable for use in the manufacture of non-inflammable films and in the preparation of a substitute for gelatine, is prepared by treating ordinary or mercerized cellulose with a halogenized fatty acid such as chloracetic or chlorpropionic acid, in the presence of caustic alkali.  In an example, cellulose is mercerized in alcoholic soda lye, separated from the excess of soda lye, treated with mono-chloracetic acid, and the mixture left to stand; when the reaction is complete, water is added with stirring to form a clear thick paste which is neutralized and from which the compound is afterwards precipitated by the addition of alcohol.  The sodium salt so obtained dissolves readily in hot or cold water, forming clear viscous solutions; the free acid resembles cellulose; the copper, lead, and aluminium salts are insoluble in water.  The Specification as open to inspection under Sect. 91 (3) (a) included a second example, according to which mercerized cellulose is moistened with soda lye, kneaded with the sodium salt of monochloracetic acid suspended in alcohol; when perfect solubility in water is obtained, excess of liquid is removed and the product washed with dilute alcohol, and then neutralized.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,178,821. Capping bottles. AMERICAN FLANGE & MFG. CO. Inc. 16 Jan., 1968 [20 Oct., 1967], No. 2364/68. Heading B8T. The invention relates to a method of selectively applying standard fluted skirt crown caps and smooth skirt tear-off closures to containers through simple modifications to a bottle crowning machine. Fig. 1 (not shown). The machine includes a rotatable crowning turret (1), a plurality of axially reciprocating crowner plunger assemblies (5), an axially disposed work-imparting shaft 11 mounted within each assembly and a downwardly spring- biased crown cap 26 engaging spindle 24. The method comprises attaching a crowner platform 33 and throat 31 assembly to the lower end of the shaft 11, applying crown caps 40 to containers 41, detaching the crowner platform and throat assembly and attaching a tear-off closure applying head and applying tear-off closures 90 to containers. Fitment and removal of the assembly and head to flange 20 is by means of three screws 35. Application of crown caps.-A crown cap 40 is introduced through an entrance port 37 and held on the spindle 24 by a magnetized split portion 27. The plunger assembly 5 is then lowered and the cap is compressed against the bottle. The spindle 24 becomes stationary while the shaft 11 continues to move the crowner throat 31 downwardly against the resistance of a compression spring 26. The relative movement between the spindle 24 and the crowner throat 31 causes the throat inner surface 32 to engage the cap and fold the skirt under the lip of the bottle 41. Application of tear-off closures.-A bottle is supplied with a closure 90 loosely seated on it. As the plunger assembly is lowered a cap holddown member 69 bears against the cap top 91 compressing a spring 71 until a cap nest 67 compresses the cap against the underlying bottle lip and anvils 75 surround the cap skirt 92. Continued downward movement of the plunger assembly causes segments 74 to move relative to the vertically stationary spindle 60 with the result that jaws 72 are cammed radially inward against the cap skirt 92. The force required to compress the cap is supplied by the spring 26 and transmitted through both the spindles 24 and 60.
