Title: Improvements in methods of eliminating fluid impurities from gaseous mixtures containing the same
IPC: C07C7/148
Filed: 1960-07-18
Abstract: Impurities such as O2, CO, CO2 and H2O are eliminated from gaseous mixtures containing them by contacting the gaseous mixtures with at least one alkali metal amide in liquid ammonia at super-atmospheric pressure.  Specified alkali metal amides are NaNH2 and KNH2 and they may be used in solution or suspension in NH3.  To increase the solubility of NaNH2 in liquid NH3, NaCl may be added. Purification is preferably effected at -70 DEG  to + 100 DEG C. and at 50-500 atmospheres.  A porous plate of fritted metal may be used to ensure good gas/liquid contact.  Examples describe (1) the elimination of O2 and CO from C2H4 intended for polymerization and (2) elimination of O2, CO, CO2 and H2O from a mixture of H2 and N2 intended for NH3 synthesis.ALSO:Impurities such as O2, CO, CO2 and H2O are eliminated from gaseous mixtures containing them by contacting the gaseous mixtures with at least one alkali metal amide in liquid NH3 at super-atmospheric pressure.  In an example, O2 and CO are removed from C2H4 intended for polyethylene manufacture.  C2H4 from liquefaction of coke-oven gas and containing 18 p.p.m. O2 and 40 p.p.m.  CO is compressed to 500 kg./sq. cm. before contact with KNH2 in NH3 at -20 DEG C.  After treatment the O2 content was <0.5 p.p.m. and the CO content <1 p.p.m.  Entrained NH3 was removed from the C2H4 by passage over molten K at 150 DEG C.

Abstract: 951,326. Electromagnetic switches. COMPAGNIE ELECTRO-MECANIQUE. July 18, 1960 [July 17, 1959; Oct. 7, 1959], No. 24984/60. Heading H2B. A unitary assembly comprising the electrical and magnetic parts of an electromagnetic contactor is housed within a two-part casing comprising a part of box-like form with one open side and a part which is readily detachable from the first part and covers the open side to retain the unitary assembly within the casing. As shown in Fig. 1, a support 3 for the core 1 has a " half bearing " 4 secured thereon by projections 4a, 4b. The armature 5 has a semicylindrical projection 5a engaging in a corresponding recess in the bearing 4 between lateral abutments 4a. The armature also has a finger 5b with a rounded end engaged by the hooked end 6a of a tie 6 attached to one end of a tension spring 7 having'its other end secured to the support 3. The spring 7 urges the armature 5 against the bearing 4 and also biases the armature towards a stop 8, with a force which decreases as the armature approaches the core 1 on energization of the coil 2 (Figs. 2a, 2b, not shown). The spring 7 may be replaced by a compression spring in a tubular guide (Figs. 4 and 5, not shown). In Fig. 6 the contactor parts are mounted on an insulating support 58 with fixed contacts 63, each engaged under two studs 58b and held by a spring 64. A base 51 is provided with internal projections 51b having slots 51c and bevelled surfaces 51d which locate the support 3 in the base. Contact terminals 54 on the base 51 cooperate with the ends of the contacts 63 and are biased by springs 55. Moving contact bridges 68 are locked in position in a bar 66 coupled to the armature 5 and biased by a contact pressure spring 69. A cover 53 provided with " quenching " compartments fits over the contacts and is secured by screws 70 to hold the contactor within the housing 51, 53. The side of the base 51 may be slotted at 73 (Fig. 9) to receive lugs of auxiliary contact assemblies 71 which have operating push-members 74 positioned so as to be actuated by a T-shaped lever 75 which moves with the movable contacts.

Title: Improvements in or relating to electric ignition devices for projectiles
IPC: F42C11/04
Filed: 1954-08-30
Abstract: 752,737. Projectile fuzes. MOTHA TREUINSTITUT. Aug. 30, 1954 [Aug. 31, 1953; Jan. 5, 1954], No. 25092/.54. Class 9(1) An impact-operated electromagnet fuze comprising a, casing 2 housing a condenser 1 and an induction coil 6 wound on a support 7 and placed between permanent magnets 8, 9 is provided with a movable core' 10. The magnets 8, 9 are segments of a ring and their upper surfaces are of the same polarity, e.g. south, so that the magnetic field is a torus surrounding the coil. A disc 3 supporting the magnets and coil has a flanged aperture into which extends the core 10, the core being suspended from an apertured disc 5 by a copper strip 11 secured on an axial stem 13 of the core. On firing a projectile equipped with the fuze, the core 10, due to inertia, sets back bending the strip 11 and lodging in the flange 4. The resultant change in magnetic field induces an e.m.f. in the coil 6, which has an end 16 connected to the condenser. The other end 17 of the coil is connected to a blade 14 mounted on an insulating member 15 and earthed by contact with the stem 13. The second terminal of the condenser is earthed by a wire 18 attached to a screw 19 which secures the member 15 on the disc 5. On set-back of the core 10, the connection between the blade 14 and stem 13 is broken and the .coil 6 disconc nected from the condenser. The ends of the strip 11 engage the underside of the disc 5 to prevent return of the core. A safety device to delay discharge of the condenser 1 through a priming detonator comprises a toothed sector 20 of insulating material connected by a gear train 24, 25 to a pivoted mass 23. As the sector rotates; a contact 26, electrically connected to the condenser 1, is carried into engagement with a contact 27 depending from the cover 28 of the casing. A pin 29 projecting from the core prevents rotation of the sector 20 until set-back of the core after firing. Whereupon, the sector is driven by its spring 22, the motion being braked by the mass 23. When the contacts 26, 27. touch, the condenser 1 can be discharged through a detonator 36, Fig. 6, containing a detonating composition 37 in which are embedded the ends of conductors 30, 31 connected in series with the condenser and a key closed after a given time delay or on impact. The delay given by the safety device is adjusted by varying the mass 23 or the strength of the driving spring 22. The contact 14 may be replaced by a rectifier. The core 10 may be a permanent magnet and the magnets 8, 9 are then replaced by a sleeve of ferro-magnetic. material. In rotated projectiles, the driving spring 22 may be replaced by a, centrifugal mass. The core 10 may be lightened by an axial recess. An alternative arrangement is described in which the condenser before firing is connected in circuit with an impact-operated member. Should this member be actuated accidentally before the end of the safety period; the condenser is short-circuited and no discharge can take place through the primer.

Title: Improvements in or relating to the manufacture of ketones
IPC: C07C45/38
Filed: 1929-08-19
Abstract: Acetone and other ketones are prepared by subjecting the vapours of primary aliphatic alcohols containing at least two carbon atoms or of certain derivations thereof in admixture with oxygen or an oxygen-containing gas to the action of high temperatures in the presence of a catalyst.  The said derivatives comprise the aldehydes or organic acid esters of the alcohols, e.g. acetaldehyde and ethyl acetate.  The catalyst comprises (a) one or more metallic oxides, hydroxides, or carbonates other than alkali or alkaline earth oxides, hydroxides, or carbonates, or (b) mixtures of one or more of the metallic compounds of (a) with one or more alkali or alkaline earth oxides, hydroxides, or salts, especially salts of weak acids, e.g. carbonates, silicates, or borates.  Where the catalyst comprises a plurality of the compounds of (a) above, these compounds are employed in the form of mixtures and not as metallic metallates formed by interaction between these compounds, whether in the catalytic reaction or otherwise.  Examples of the catalysts used are mixtures of one or more oxides, hydroxides, or salts (e.g. carbonates, borates, or silicates) of calcium, barium, magnesium, or other alkaline earth metal with one or more of the following:-iron oxides, copper oxide, nickel oxide, cobalt oxide, manganese oxides, lead oxides, cerium oxides, uranium oxides.  The catalysts may be employed on filling or contact materials such as pumice, kieselguhr, or the like.  The reaction may be performed at temperatures between 200 DEG and 700 DEG  C., and especially at temperatures between 350 DEG  and 550 DEG  C., and at any desired pressure.  The reaction mixture may be treated in any convenient way.  For example it may be passed in a rapid stream through a tube or other apparatus (e.g. of copper, iron, a chromium nickel steel such as staybrite, earthenware, or the like) filled or provided with the catalyst and heated to the desired temperature.  The preferred proportions of the mixture are more than two molecules of oxygen to each molecule of alcohol or to two molecules of alcohol derivative, and larger proportions of oxygen e.g. 5 : 1 or 20 : 1, may be employed.  The process may be performed in the presence of aliphatic acid vapour.  In the examples a mixture of alcohol, oxygen, and acetic acid in the proportions 1 : 5 : 1 is passed through a copper tube filled with an equimolecular mixture of ferric oxide and calcium carbonate and maintained at 450-480 DEG  C. The crude acetone produced can be purified by fractional distillation.

Filed: 1923-10-10
Abstract: 210,739. Eclipse Machine Co., (Assignees of Whitney, M. P.). Feb. 3, 1923, [Convention date]. Turning-gear.-In an engine starter of the Bendix type, the driving member is disengaged from the engine fly-wheel, if the latter turns backwards, by means of two rotary elements which are separate from the transmission gear and come into co-operation with the fly-wheel and the driving member respectively. As shown, the driving member comprises a pinion 5 having a flange 13 in contact with a control member or nut 12, which is mounted on a screwed sleeve driven from the shaft 2 of an electric motor 1 through a spring 10. The nut 12 has teeth for engagement with a pinion 19 connected by a freewheel clutch to a pinion 18 slidable on a shaft 7 into engagement with the fly-wheel 6. The pinions 5 are normally held out of engagement with the fly-wheel by springs 14, 20. During normal starting, the pinion 5 is moved automatically into and out of engagement with the fly-wheel by the action of the nut 12 and spring 14. The nut 12 moves the pinions 19, 18 by engagement with a disc 27 on the pinion 19, and the pinions 18, 19 are driven in opposite directions by the fly-wheel 6 and the nut 12 respectively. If the fly-wheel turns backwards, the rotation of the pinion 18 is transmitted through the free-wheel clutch and tha pinion 19 to the nut 12, which is withdrawn along the screwed sleeve, so that the pinion 5 is no longer driven by the starting motor and is free to be returned by tha spring 14.

Abstract: 355,512. Weighing-apparatus for filling bottles, tins, &c. VAVERKA, A., 4, Rue Rollon, Rouen, France. Aug. 25, 1930, No. 25325. Convention date, Sept. 5, 1929. [Class 143.] An electrically-controlled semi-automatic weighing apparatus for filling receptacles with thick or viscous liquids, pasty or powdered materials comprises a cock 22 (fed either directly or from a reservoir 25 maintained at a constant head) opened by a hand-lever 24 and closed automatically by a counterweight 20 retained during the filling operation by a plunger 5 engaging a notch in a slide or bar 12 which is fitted into a flat formed on a rod 8 to prevent the same from rotating, two collars 10, 14 being provided on the rod to limit its sliding movement. The receptacle to be filled is placed on a scale pan 27, and the cock 22 is opened by raising the handle 24. The rise of the handle rocks a lever 18 and depresses the slidable rod 8 so as to close electric contacts 11, 13 in circuit with an electromagnet 45, and also allow the spring- pressed plunger 5 to enter the notch in the bar 12. The circuit however remains open at a lever contact 40 controlled by the scale beam 31 upon which the scale pan is supported by a ball 50. The scale pan is further supported by a ball-bearing collar 29. When the requisite weight has entered the receptacle,' the depression of the scale beam permits the lever contact 40 to close the circuit of the electromagnet 45 which then withdraws the plunger 5 and permits the weight 20 to close the feed cock. The position of the recess for receiving the plunger 5 may be adjusted to vary the feed opening of the cock. The weighing mechanism is protected by casings 30, 34 and may be adjusted vertically by raising or lowering its supporting tube 37.

Abstract: 464,078. Automatic volume control. SIEMENS & HALSKE AKT.-GES. Sept. 17, 1936, No. 25342. Convention date, Sept. 17, 1935. [Class 40 (iv)] . [Also in Group XL] An amplitude filter of the balanced-bridge or bridged-T type produces maximum attenuation at an amplitude other than zero. In the bridged-T circuit shown in Fig. 2 the arms R<1>, R<2> comprising dry-plate rectifiers in series and in parallel, or like non-linear resistances, have resistances which vary with voltage as shown in Fig. 4 as opposed to Fig. 3. The attenuation then reaches a maximum at a finite voltage U‹. The requisite values of the non- linear resistances R<1>, R<2> are obtained by varying the number of dry-plate rectifiers, by coupling the rectifiers through a transformer, Fig. 5 (not shown) or by shunting them by a resistance, Fig. 6 (not shown). A section corresponding to Fig. <3> may be connected in cascade with a section corresponding to Fig. 4. Fig. 7 shows the resulting attenuation (ordinate) plotted against input voltage (abscissa) at b<3>, the attenuation for the separate sections being shown at b<1> and b<2> respectively. An alternative arrangement having similar effects is shown in Fig. 9, where the rectifiers G<1>, G<2> are biassed by means of batteries B<1>, B<2> and resistances so that the bridge is balanced and consequently gives high attenuation at a suitable value of the input voltage. The non-linear elements may comprise dry-plate rectifiers, resistors with a high temperature coefficient, or thermionic valves. Specifications 415,173 and 457,236, [Group XL], are referred to.
