Abstract: 251,984. Bellini, E. May 8, 1925, [Convention date]. Directive signalling; thermionic amplifiers and detectors. - In order to maintain symmetry in a loop aerial C tuned by a condenser B and earthed at its mid-point, the capacity and resistance of the gridfilament circuit of the receiving - valve H are balanced by the equal capacity and resistance of an auxiliary valve E, connected to the opposite side of the tuning-condenser. The auxiliary valve E may be idle or may have its output coil connected in series or in parallel with the output coil of the receiving-valve H. The auxiliary valve may be used for reacting by means of a coil D on a coil A connected across the tuning-condenser B. The coil A may be split and its two halves connected in the loop circuit on opposite sides of the condenser B. The reaction coil D mav be arranged to induce oscillations in the aerial for heterodyne reception. The valve filaments are earthed, and the mid-point of the loop is earthed through a resistance F. The Specification as open to inspection under Sect. 91 (3) (a) states that a condenser and a resistance may replace the auxiliary valve. This subject-matter does not appear in the Specification as accepted. Specification 217,585 is referred to.

Title: Mechanical scale translating device for spectrographs
IPC: G01J3/06
Filed: 1951-05-21
Abstract: 704,358. Indicating-apparatus. COMPAGNIE RADIO CINEMA. May 21, 1951 [May 25, 1950], No. 11789/51. Class 106 (4). [Also in Group XX] In a device for use with spectrographs and spectroscopes for enabling the distances between spectral lines which approximately follow a hyperbolic law to be read on a linear scale and which comprises a V-shaped member rotatable in its plane about its apex, one arm of said member being engaged by a first moving body which is constrained to move along a first straight path in such a manner that the displacements thereof are proportional to the distances separating the spectral lines, the second arm being engaged with a second moving body constrained to move along a second straight path parallel to the first path, and means connecting the second moving body with an element which moves over a linear wavelength scale, the first arm is substantially perpendicular to both paths when the first moving body is at its starting position and has a sinuous profile so that for each movement of the first moving body the V-shaped member is rocked to such an extent that the movement imparted to the second moving body by the second arm compensates for the discrepancies between said distances and said hyperbolic law and preferably also for mechanical imperfections in the various elements of the device. The device shown comprises interconnected rotatable screws 3, 4 of different pitch, on screw 4 of which is threaded a bush (not shown) connected to a scanning device (e.g., a photo-electric cell associated with a slit) movable across a spectrum while screw 3 has threaded thereon a bush 7. Rotation of the screws to move the scanning device into register with the different spectral lines thus causes a proportional displacement of the bush 7. This bush carries a bearing 8 which contacts one arm 2 of a V-shaped member pivoted at 6, this arm having a sinuous profile, so that movement of the bush 7 rocks the V-shaped member and the arm 1 thereof moves a bearing 10 on a rack 22. Movement of this rack rotates a pinion 15 and causes a pointer 17 to move over wavelength scale 18. A spring 16 urges pointer 17 in the direction 20 and this tends to move the rack in the direction 21 whereby contact is maintained between the bearings 10, 8 and the arms 1, 2.

Title: Vaccines comprising inactivated myxoviruses
Inventor: KANAREK ALEXANDER DAVID
IPC: C12N7/06
Filed: 1964-03-20
Abstract: A vaccine comprises antigens derived from myxoviruses inactivated by a process which comprises contacting the viruses in aqueous suspension at pH 6-8 in the presence of at least about 0.05% w/v. of a non-ionic hydrophilic surface active agent with a fully or partially chlorinated, or chlorinated and fluorinated C1-5 hydrocarbon, other than CHCl3, which is liquid at 15-25 DEG C. Specified myxoviruses are M. influenzae-A, B, and C, M. parainfluenzae-1, 2, 3, and 4, M. multiformae, M. pestigalli, M. parotidis, measles virus, distemper virus, rinder-pest virus, and respiratory syncytical virus.  The non-ionic surface active agent may be a polyoxyethylene sorbitan mono-oleate or another polyoxyalkylene ether of partial lauric, palmitic, stearic or oleic acid esters. Specified halogenated hydrocarbons are CCl4, CHCl= CCl2, CCl2=CCl2, CFCl2.CClF2, CCl3.CH2.CCl3 and Cl2.C=C.Cl-C.Cl=C.Cl2.  Any strain of the selected virus may be used.  The virus may be cultivated on chick embryo or monkey kidney tissue cultures, stable diploid cell line culture or, where appropriate, in embryonated hens' eggs.  The tissue culture fluid or harvested allantoic fluid is clarified and the virus therein is inactivated by contact with the above organic solvent. The organic solvent is subsequently removed, leaving an aqueous suspension containing inactivated fragmented virus particles, i.e. the primary vaccine.  Stabilizers, e.g. polyvinyl pyrrolidone or dextran, and protamine sulphate, may be added.  The primary vaccine may be purified or concentrated, e.g. by adsorbing the fragments of inactivated virus on to aluminium oxide or hydroxide or an aluminium salt (e.g. phosphate or alum) substantially isoluble at pH 6-8. Alternatively, a soluble aluminium salt may be added in solution to the primary vaccine and alum precipitated therefrom by the addition of an appropriate potassium salt and adjustment of pH to the required value.  The adsorbate may be separated and resuspended in a saline solution buffered to pH 6.0-8.0.  The purified or concentrated vaccine may be mixed with other vaccines, or the aluminium salt, oxide or hydroxide may be used to adsorb other materials having different antigenicity.
Patent GB-651882-A (GB)
Title: Improved process for the concentration of sulfuric acid
IPC: C01B17/88
Filed: 1948-04-30
Abstract: <PICT:0651882/III/1> <PICT:0651882/III/2> Spent sulphuric acid from an olefin-hydration process is concentrated by passing the spent acid through a series of compartments (e.g. a Simonson-Mantius concentrator) maintained at increasing temperatures, foaming being prevented by adding a petroleum oil boiling above 600 DEG  F. to the last compartment, and withdrawing concentrated acid from the last compartment.  High, non-fluctuating liquid-levels in the compartments are thereby obtained.  A small quantity of a fatty acid may also be added to the last compartment.  Spent sulphuric acid (45 per cent) is supplied through line 11 into the first compartment of concentrator 10, and is heated to 284 DEG  F.  The concentrator has four compartments each of which contains bayonet-type heaters supplied with a hot mixture of diphenyl and diphenyl oxide.  The acid flows through the second and third compartments, maintained at 293 DEG  and 309 DEG  F. respectively, by means of conduits 12 and 13. The acid then passes through conduit 14 into the fourth compartment which is maintained at 334 DEG  F.  A petroleum oil (boiling range 647-856 DEG F., degrees of specific gravity 28.2) containing 100 c.c. oleic acid per gallon is added to the fourth compartment through line 16; the amount added being 4 gallons each 8 hours during which time 224,000 pounds of acid (100 per cent basis) is handled.  Steam is withdrawn from all the compartments through conduit 17; and concentrated acid (70 per cent) is withdrawn from the last compartment through line 15. After the initial period of settling down, the rate of oil-oleic acid addition may be reduced to 1/2 gallon each 8 hours without occurrence of foaming.  Other fatty acids which may be used are stearic, palmitic, arachidic, erucic and rapinic.  The 70 per cent acid is preferably raised to 95 per cent by vacuum-concentration.

Patent GB-345129-A (GB)
Title: Apparatus for packing cigarettes or similar articles
IPC: B65B19/28
Filed: 1930-04-16
Abstract: 345,129. Packeting cigarettes. NENNINGER, F., 6, Shuttleworthstrasse, Vienna, and UNITED CIGARETTE MACHINE CO., AKT.-GES., 5, Junghansstrasse, Dresden, Germany. April 16, 1930, No. 12055. [Class 94 (i).] In a machine in which cigarettes and similar articles are forwarded from a supply hopper in layers towards a boxing device, incomplete layers are eliminated and the drive of the boxing and other subsequent devices is interrupted for the space of one cycle of operations. The cigarettes are contained in a hopper 1, Fig. 2, having sloping sides, and gravitate towards a number of vertical walls 2 forming guide channels. The walls are secured to spindles 2a, Fig. 5, on rails 3 supported by crank arms 4 from a rail 5 adapted to be horizontally displaced by a cam 8 on a vertically movable guiderod 9, so as to have a swinging movement. The cigarettes fall on to a guide track 10 formed with grooves 10a and are moved along to the right, Fig. 1, by rods 12 on chain wheels 12b, 12c. The grooves gradually become nearer as they approach the filling device. Above the guide track a series of filler rollers 14, Fig. 9, is mounted, one for each groove, and the passage of the cigarettes causes them to assume the position shown. If, however, no cigarette is present, the roller drops and the arm 15 engages a groove in a displaceable stop-rod 22, Figs. 8 and 9, and prevents it from making a transverse movement which, if not arrested, it makes intermittently under the action of a spring 24. A stop 33 is thus prevented from engaging with a bell-crank lever 29, and a plate 27, which is carrying the cigarettes, is allowed to swing downwards and eject the incomplete layer. Simultaneously, a double-armed lever 42, 42a is allowed to rotate so that the lower end pushes a stud 37, axially mounted in a disc 36, and causes it to project from the other side. On the further intermittent rotation of the disc, the projecting stud engages a slide 44 and causes the moving parts of the boxing apparatus to be held motionless for one cycle of operations. The boxing apparatus comprises a revolving table 60, Figs. 12 and 15, carrying containers 56 open at the top and sides and pivotally mounted on arms 59. The complete layers are carried on to a table 45, arranged to be progressively lowered until the requisite number of layers has been collected. The table forms the bottom of a collecting container having fixed sides 46, one end being constituted by a movable plunger 47. A plate 57 descends and presses down and aligns each layer of cigarettes. On the completion of the batch the plunger 47 forces it into the container 56. The table 60 moves through one step of its travel and an open-topped box is placed, upside-down, over the container and cigarettes. The container and box are subsequently inverted by the engagement of a rack with a toothed wheel on the axis, and a stamp 71 forces the box and contents on to a delivery conveyer 72.

Title: Improvements in and relating to the condensation of di-alkyl succinates
Inventor: INGRAM DONALD WILLIAM
IPC: C07F1/00
Filed: 1953-05-01
Abstract: A process for the production of dialkali metal derivatives of dialkyl cyclohexa-1,4-diene-2,5-diol-1,4-dicarboxylates comprises contacting a di-alkyl succinate with an alkali metal alkoxide in the presence of at least one organic diluent, which is a liquid under the reaction conditions and which is either a hydrocarbon or a dialkyl succinate, the total dialkyl succinate : alkoxide molar ratio when using an excess of dialkyl succinate as diluent being greater than 1 : 1.  The alkoxide may be employed alone or dissolved in a lower alcohol, conveniently that corresponding to the alkoxide.  Dimethyl and diethyl succinates and sodium methoxide and ethoxide are mentioned as suitable starting materials.  Alcohol employed as solvent for the alkoxide should be removed after the reaction.  The organic diluent may be a paraffinic hydrocarbon such as n-hexane, isooctane, an inert higher hydrocarbon fraction or an aromatic or alicyclic hydrocarbon such as decahydronaphthalene, tetrahydronaphthalene or a xylene fraction.  By use of a suitable diluent aliphatic alcohol present in the reaction mixture may be removed by distillation, e.g. azeotropic distillation.  The liquid diluent may be recycled. The reaction may be carried out batchwise or continuously.  In examples dimethyl disodiocyclohexa-1,4-diene-2,5-diol-1, 4-dicarboxylate-dimethanolate is obtained by reacting dimethyl succinate dissolved in decahydronaphthalene with sodium methoxide in a nitrogen atmosphere (1); in a similar process a large excess of dimethyl succinate is added to a mixture of sodium and methanol, methanol is distilled from the reacted mixture and the desired product filtered off and washed with ether (2); dimethyl succinate and sodium methoxide are reacted together in a nitrogen atmosphere in the presence of varying amounts of methanol (3). The Provisional Specification includes the use as starting materials of lower aliphatic esters of substituted succinic acids of the general formula ROOC.CH2CHR1COOR wherein R is an alkyl group and R1 is an alkyl, aryl or aralkyl group with the production of the correspondingly disubstituted cyclohexa-1,4-diene-2,5-diol-1,4-dicarboxylates.
