Title: Improvements in or relating to the purification of gas from oxide of nitrogen
IPC: C10K1/32
Filed: 1937-05-19
Abstract: In the removal of nitric oxide from hydrogensulphide-containing gases by passing the gas over a metallic sulphide mixed with humous material, or over a naturally occurring humous-containing oxide such as bog iron ore, the complex sulphide-nitric oxide compound formed mixed with the humous material is regenerated by passing air over the mass in a purifier box.  Free sulphur is liberated in the latter and the same box is again used for purification of the gas followed by regeneration until sufficient sulphur is accumulated for its recovery.
Patent GB-753173-A (GB)
Title: Reconstitutable, aqueous polyvinyl acetate emulsion powders and process for manufacturing same
IPC: C08J3/16
Filed: 1954-05-13
Abstract: Dry polyvinyl acetate powders preponderantly of particle size less than 5 microns and reconstitutable to the original emulsion are prepared from aqueous polyvinyl acetate emulsions by atomizing and drying at a temperature such that the dried particles are maintained below their sintering temperature.  The atomizing is preferably effected by a stream of air of velocity high enough to form globules containing individual particles and the inlet temperature of the air may be from 160 DEG  to 250 DEG  F. with an outlet temperature of 115 DEG  to 125 DEG  F.  A suitable spray drier is described. Alternatively a freeze-stable emulsion is frozen in less than ten seconds, e.g. at or below -40 DEG  F., the water is evaporated under high vacuum while maintaining the frozen state and the resultant cake is powdered.  Either process may be carried out continuously instead of batchwise.  The original emulsions may contain 50 to 55 per cent solids or may be diluted to 15 to 35 per cent and can be prepared as described in Specifications 466,173 and 641,653.  The original emulsions are preferably free from plasticizers (such as dibutyl phthalate, butyl phthalyl butyl glycolate, dibutyl sebacate and tricresyl phosphate) as these cause a reduction in the sintering temperature, but they may be present in or added to the powder or the reconstituted emulsion, along with fillers and pigments.  The products are useful as additives to polyvinyl acetate emulsion adhesives containing plasticizers, and in making paints.  The powders may be sifted on to a fibrous base to give, on heating, bonded non-woven fabrics. In examples sintering temperatures given are 115 DEG  and 160 DEG  F. Specification 615,723 also is referred to.

In the modification shown, adsorber 1 is being charged, and exit gas is led by pipe 10 through adsorbers 2 and 3 undergoing drying and cooling respectively. Part of the gas is recycled by pipe 11 and part is discharged by pipe 13. By means of the automatic throttle 14 the fan 7 may be caused to create a. pressure gradient which draws the gas through adsorber 1 as well as effecting the recirculation.
Patent GB-461167-A (GB)
Title: Improvements in or relating to the guiding of filaments, threads or yarns
IPC: D01D10/04
Filed: 1936-05-19
Abstract: In a method of guiding filaments, threads, or yarns whilst conveyed with their successive convolutions in spaced relationship along rollers over which they are helically wound, the filaments, threads or the like are passed over a guide bar interposed between said rollers, the surface of which bar not only intersects the plane containing the axis of the rollers or a plane symmetrical thereto but also a plane at right angles thereto and parallel to each roller axis.  A thread or filament 1 passes from a source of supply over a guide bar 2 to rotating roller 3 and thence in spaced convolutions over fixed guide bar 4 and rotating rollers 3, 5.  The <PICT:0461167/IV/1> <PICT:0461167/IV/2> <PICT:0461167/IV/3> <PICT:0461167/IV/4> pitch of the successive convolutions becomes smaller as the thread passes along the rollers.  In a modification two fixed guide bars may be provided with a guide eye or hook to help the transfer of the filament from one to the other.  In a modification shown in Figs. 5, 6, skew rollers 11, 12 are provided with two guide bars 9, 10.  In this case the convolutions become nearer together at first due to the skew rollers and the guide bar 9 and then when the bar lies inside the rollers, the difference in pitch is due to the skew rollers only and finally the pitch again decreases as the thread comes on to bar 10.  Instead of a fixed bar a freely rotatable roller may be used.  Specification 448,774 is referred to.

Title: Improvements in or relating to spectroscopic devices
IPC: H05H1/00
Filed: 1962-04-12
Abstract: 1,008,361. Glow discharge lamps. LITTON SYSTEMS Inc. April 12, 1962 [April 14, 1961], No. 14199/62. Heading H1D. A method of producing the emission spectrum of a material comprises bombarding the material by the ions of a low pressure discharge to sputter atoms from the material, and exciting the sputtered atoms to higher energy levels. In the embodiment, the material to be examined, 122, 'is sputtered into the space above the magnet 59 by a discharge between anode 56 and mercury cathode 26. The magnetic field causes electrons in this space to spiral, and so increases the probability of exciting the emission spectrum of the sputtered material. The emission spectrum may be viewed either through a window normally protected by a shutter 112, which may be raised by an external magnet to the position 112a, or by observing a mirror inside the tube through a window protected by a shutter from direct deposition of material from the discharge space, Fig. 5 (not shown). The mercury pressure in the tube may be controlled by the temperature of the water jacket 22 surrounding the mercury cathode, or a rare gas may be admitted at the inlet 30, and mercury in the upper part of the tube removed by filling the cold thumb 39 with liquid N 2 , and evacuating at 15. The specimen to be examined may be replaced by removing the upper vessel 12 at the 0-ring coupling 36, and several specimens may be mounted on the plate 58, being sputtered in turn by suitable adjustment of the magnetic fields &c. An ignition electrode 52 may be provided, together with a molybdenum circular strip spot anchor 27, auxiliary anode 54 and graphite grid electrode 50. Specification 1,008,362 is referred to.

Title: Process for removing nicotine from tobacco
IPC: A24B15/26
Filed: 1925-05-29
Abstract: In the process set out in the parent Specification, the solvent employed for recovering the extracted nicotine dissolves also some of the ammonia gas, and, according to the present invention, the solvent is freed of ammonia, as by passing it upwards through water, preferably in streams or bubbles, or by bringing it into intimate contact with gas such as air.  The water may be saturated with a salt such as sodium chloride.  In treating the solvent with gas, the gas may be bubbled into it, or the solvent may be brought to a finely-divided state by falling in thin sheets or little drops, or it may be caused to flow over solid materials, such as pebbles, and a current of air passed over it; the ammonia led off by the gaseous current is recovered, for example, by contact with an acid.

Patent GB-1111121-A (GB)
Title: Improvements in and relating to pulse counting apparatus and to the measurement of radiation from radioactive materials using pulse counting apparatus
Inventor: FINCH HAROLD WILLIAM STUART
IPC: G01T7/08
Filed: 1964-04-07
Abstract: 1,111,121. Counters. ISOTOPE DEVELOPMENTS Ltd. 26 April, 1965 [7 April, 1964], No. 14253/64. Heading G4D. [Also in Division G1] In pulse counting apparatus for measuring the radiation from radioactive samples presented sequentially by an automatic sample changer, during any one timed counting interval of a number of intervals which make up a complete sample measurement count, pulses are first counted by a background scaler 7a or 7b until the number of pulses counted becomes equal to a periodically updated, stored background count, and then the rest of the pulses for the interval are fed to the main scaler 3 to obtain the count representing the wanted radiation from the material. After each measurement, a trend follower unit 31 is arranged to receive only background pulses, and it responds to any significant change in the average level of the background radiation impulse rate by preventing the presentation, by the sample changer, of a new sample, and by initiating a fresh measurement of the background. This measurement is recorded in one of the two background scalers 7a, 7b, in a time interval determined by the selector 25. The count previously stored in the scaler 7a or 7b is cancelled and the new count read in. Then a new sample can be presented for measurement. Now, the signals are supplied so that the scaler having the stored background count recorded is reduced to zero, while the scaler previously recording a zero count is made to count upwards. When the background count is attained in the background scaler counting upwards (and zero attained in the other), further pulses are diverted to the main counter 3 to record the radiation from the sample. During the next timing interval, the operation of the scalers 7a, 7b is reversed, the background count afterwards still being retained in one of them. This process is repeated for a number of intervals, as stated above, until a predetermined count or time is attained.

Title: Improvements in gas or vapour filled electric discharge devices and circuits therefor
IPC: H01J3/02
Filed: 1934-05-11
Abstract: 438,360. Thermionic valves; circuits. ROBINSON, J. A., 171, East Mosholu Parkway, North, Bronx, New York, U.S.A. May 11, 1934, No. 14299. Convention date, Dec. 29, 1933. [Classes 39 (i) and 40 (v)] A gas- or vapourfilled valve has a first grid surrounding the cathode charged to a positive potential less than the ionization potential of the filling, a second grid surrounding the first and oppositely charged, and an anode. In one form, a relay valve 1 has a cathode 2, a first grid 4 at six volts positive, a second grid 5 at thirty volts negative and an anode 6 at one hundred and twenty volts positive. The discharge is confined to the space inside the anode by mica members 8, 9 or by a transverse field. The valve 1 has a mercury amalgam filling and is supported by means of collars 10, 13 in an outer evacuated envelope 14. The grids 4, 5 may be slotted or perforated, and two or more amplifier units may be mounted in a single envelope. The relay is shown operated by a photo-cell 20 in the lead supplying the outer grid 5 with out-of-phase negative voltage. The inner grid is supplied with in-phase positive voltage from the potentiometer 23. With this arrangement, light incident on the cell causes an interruption in the discharge through the relay. If the photo-cell is placed in the lead to the inner grid, light incident on it initiates a discharge in the relay. The relay may be used for continuous control if the grids each comprise a large number of turns.

IPC: B21K1/58
Filed: 1969-03-19
Abstract: 1,201,884. Forging; extruding; making rivets. OLYMPIC SCREW & RIVET CORP. 19 March, 1969, No. 14365/69. Headings B3A, B3H and B3P. A four-blow header comprises four punches which co-operate with two or four dies to forge a rivet from a cylindrical blank, the rivet being headed and formed with a blind cavity at one end and with slots to define sectors on the shank by the first two punches and the cavity being extended to overlap the slots by one of the other punches. In a first embodiment with four punches (15)-18, Figs. 1, 2 (not shown), and four dies (20)-23, the first punch and die set head a cylindrical blank and a pin (42) slidable in the punch (15) forms a cavity in the head. The rivet blank (B) is then ejected and transported to the second punch and die set, Fig. 2 (not shown), wherein the cavity is enlarged and the rivet head formed into a countersunk head (67). At the third punch and die set 17, 22, Fig. 3, the shank is slotted by a piercing pin 75 with three radial flutes (77), Fig. 4 (not shown). The slotted rivet blank Bb is ejected by three pins 79 slidable through the piercing pin. The punch 18 at the fourth punch and die set 18, 23 floats in a casing 86 and is spring-biased forwards. A piercing pin 96 projects from the punch and forces the rivet blank R into the die 23 to pierce it. Since the blank is confined by the wall of the die bore 103 the rivet is extruded rearwards over the pin to force the punch 89 rearward against spring bias. The pin 96 also causes the slots 106 to close. In the second embodiment a set of four punches (25)-(28), Figs, 7-10 (not shown), co-operate with a pair of dies (31), (33) to forge the rivet. The punches are substantially identical with the four punches of the first embodiment. In this embodiment, however, the blank is slotted in the die (33) during the first heading blow.
