Title: Safety system for use in a subterranean well
Inventor: DRUMMOND GAVIN
IPC: E21B43/1185
Filed: 2006-11-23
Abstract: A safety system is disclosed for use in perforating operations whereby a firing head 20 may be isolated from a perforating gun 18 by means of a detonation transfer interrupter 22. The interrupter 22 maintains a sufficient separation between the detonation transfer components to prevent the transfer of detonation between the components. After installation of the perforating assembly 12 in a well, the interrupter separation is decreased to allow detonation to occur. The firing head 20 is positioned at a distal end of the perforating assembly 12. The interrupter 22 may additionally be used to detach the firing head 20 from the remainder of the perforating assembly 12, so that the perforating gun 18 can be retrieved from the well separate from the firing head 20.

Patent GB-400520-A (GB)
Title: A process for obtaining female sexual hormones
Filed: 1933-04-03
Abstract: Female sexual hormones are obtained in crystalline condition from crude products extracted from animal or human urine by treatment of the crude products in presence of water, but in absence of organic solvents, with a hydroxide or monoxide of a metal of the second periodic group until an easily disintegrated powder is obtained, filtering off the powder, acidifying the filtrate and aqueous washings of the powder, extracting with a solvent immiscible with water and purifying the extract in known manner.  According to one example, a butanol extract of the urine of a pregnant female is distilled to remove the solvent, and steam distilled to remove volatile impurities.  The residue is repeatedly kneaded with milk of lime, the clear liquid being decanted, until the resinous mass is broken down to powder.  The final suspension is filtered and the powder is ground with water containing calcium hydroxide and again filtered and extracted with water.  The united aqueous extracts are acidified and extracted with ether free from peroxide, or with benzene, ethyl acetate, butanol or chloroform.  The ether extract is washed, first with dilute sodium bicarbonate solution and then with dilute sodium carbonate solution, and evaporated to small volume. The crusts of crystallized hormone which form are mixed with ethyl acetate, kept for some time at -10 DEG  C., filtered off, dissolved in boiling alcohol and decolorized with animal charcoal.  The solution is filtered, evaporated in a water bath until crystallization begins, cooled to -10 DEG  C. and the crystals filtered off.  A hormone of melting point 272-276 DEG  C. is thus obtained.  A further crystalline hormone of M.P. 250 DEG  C. may be obtained from the residue on evaporation of the ethyl chloride mother liquor.  According to another example a somewhat similar process is employed, but the steam distilled residue of a butanol extract of urine is again steam distilled with milk of lime before treatment with milk of lime to obtain a powder, and the crystalline mixture of hormones remaining after evaporation of the ether extract, is extracted with 1 per cent caustic soda lye, the extract filtered, and the filtrate again extracted with ether.  The ether is evaporated to leave a resinous substance, which on addition of ethylacetate with or without petroleum ether yields crystals of composition C18H22O2 melting at 256 -258 DEG  C.  The caustic soda solution which has been extracted with ether is saturated with carbon dioxide and again extracted with ether.  This ether solution yields crystals of composition C18H24O3 melting at 276-277 DEG  C.  Other examples are given wherein milk of lime is replaced by a suspension of magnesia, barium hydroxide or zinc oxide, or the initial material to be treated is an ether extract of urine.  The urine of pregnant mares may be employed. The treatment of ovaries or placenta or extracts thereof with alkaline earth hydroxides is referred to as already known.

Title: Process for manufacturing from animal hoofs or horns, buttons similar to corozo buttons
IPC: B29D19/04
Filed: 1933-04-03
Abstract: The preparation of buttons similar in appearance to corozo from hoof or horn includes the successive steps of scouring, forming the buttons by mechanical operation, polishing the rough buttons, again scouring, colouring and again polishing.  The scouring is carried out in a rotary container with maize cob stripped of grains.  The plates are then ventilated for 48 hours, subjected to a turning operation on both faces, and mechanically pierced.  The polishing is carried out in a rotary container, first by means of chips of hard wood, which is then removed and a mixture of sawdust, powdered corozo and powdered pumice substituted, and finally the mixture is replaced by chips of hard wood to which a little plaster and oil are added.  Now the buttons are bleached by means of hydrogen peroxide or scoured with a white soap, and coloured black or, with the addition of zinc hydrate, in any tint. The buttons are allowed to dry with white corozo powder. Before the final polishing, hollow buttons are again scoured by means of a mechanically driven brush impregnated with water, powdered carbon and plaster.  The buttons are polished by means of a mixture of powdered corozo, wood powder and plaster, and then by means of small pieces of wood to which a burnishing agent, e.g. oil, may be added.

Title: Improvements in devices for measurement of stray-light, more particularly that due to turbidity
Inventor: LEITERER LOTHAR
IPC: G01N21/47
Filed: 1956-04-04
Abstract: 829,303. Turbidometers; photometers. ZEISS JENA, C. VEB. April 4, 1956, No. 10352/56. Classes 97(1) and 97(3) [Also in Group XL(b)] In a device for measuring stray light #x, more particularly that due to turbidity of a specimen 4 illuminated by a measuring beam of light #m, by comparison with stray light from a body 5 illuminated by .a reference light beam #v, the two beams originating from a common source 1, means 8, 9 10 are provided for deviating a portion of the measuring beam into the reference beam to compensate for stray light #s due to either undesired false stray light produced by the apparatus itself or the basic turbidity of the medium in which the specimen is placed. A shutter 3 occults the two beams alternately and the comparison is effected photo-electrically by means of cell 6 feeding an amplifier-indicator 7. A measuring instrument M in the form of a neutral grey wedge may be placed in either the measuring or reference beam and adjusted to balance the :lights reaching the photo-cell in known manner. 10 is a neutral grey wedge for adjusting the intensity of the compensating light. In an alternative way of carrying out the invention, where the measuring instrument is included in the reference beam, a suitable proportion of light is shunted round the instrument as indicated at C. In order that the compensation may be effective, not only for peak values of light when shutter 3 is fully open, but also during transitions, it is necessary that the reference and compensating light beams should coincide in size, position and orientation at the plane of the shutter. This involves an image-transposing optical system in the path of the compensating light between the measuring and reference light beams to compensate for the difference in length of the light paths, and means, such as a Dove prism, to introduce supplementary reflections where beam splitter 2 introduces one more reflection in the reference beam than the measuring beam. The application of the invention to a nephelometer for microbiological purposes is described.

Filed: 1928-04-05
Abstract: 316,907. MacCallum, A. E. G. April 5, 1928. Roller-and-breast mills. - In a grinding mill having a grinding bar or block e arranged longitudinally of a. grinding roll d, a feed hopper b disposed above the roll is provided with a partition element a, Fig. 1, or l, Fig. 3, so arranged as to remove material which has passed between the grinding roll and bar and allow it to accumulate until it overflows the partition on to the grinding roll for the purpose of a repeated grinding. The scraper a, Fig. 1, is mounted on a shaft c and is maintained in contact with the roll by a torsion spring f, Fig. 2 (not shown), and may be withheld from the roll by a latch i engaging a handle h. The material after passing between the bar e and roll d adheres to the surface of the roll and is carried round to the hopper b where it is removed by the scraper a, the material gradually accumulating between the scraper a and the wall of the hopper until it overflows and mixes with the material in the hopper from which it is reground. The hopper b in Fig. 3 is subdivided by a partition k, the space between the partition and roll being closed by the pivoted scraper l which may be mounted in a manner similar to that of the scraper a. The part m of the hopper is filled with material to be ground and a shallower layer is placed in the other division n on top of the grinding roll d. Clockwise rotation of the roll d carries the material under the bar e and round to the back of the machine into the space m whereby it is scraped off the roll by the blade l increasing thereby the contents in the space m and causing same to overflow into space n from which it is again ground. This process is repeated until the whole of the contents of the hopper b is sufficiently ground, the blade l is then pivoted to the position shown in broken lines and the contents collected by a scraper on the roll in known manner.

Title: Improvement in method of reducing the nicotine content of tobacco
IPC: A24B15/26
Filed: 1934-04-06
Abstract: The nicotine content of tobacco, whether in leaf or cut form, or in cigarettes or cigars, and also whether packaged or not, is reduced, and the quality improved, by subjecting it to the action of ethylene oxide in the presence of at least 8 per cent of moisture.  The ethylene oxide is preferably used in gaseous form, to the action of which the tobacco is subjected in an evacuated chamber.  The extent to which the nicotine is reduced may be varied by altering the concentration of the ethylene oxide gas, the duration of exposure thereto, the quantity of the charge of tobacco treated, and the moisture content.  Also the effect of the ethylene oxide gas may be reduced by the addition of carbon dioxide or air.  Homologues or derivatives of ethylene oxide may be used, e.g. propylene oxide. Also solutions in water may be used instead of gas.  The process reduces the acidity of the tobacco.
