Title: A tuning and indicating device for combined am and fm receivers
IPC: H03J5/00
Filed: 1952-10-31
Abstract: 714,029. Adjusting radio apparatus. STANDARD TELEPHONES & CABLES, Ltd. Oct. 31, 1952 [Nov: 10, 1951], No. 27443/52. Class 40 (5) In a receiver employing separate tuning and indicating means for two wave-ranges (e.g. in a combined frequency-modulation and amplitudemodulation receiver), the tuning over both ranges is carried out by means of the same driving shaft and the changeover from one range to the other is so performed by means of a wavechanging. switch, that the tuning and the indication for each range are unaffected by the changeover to the other. Rotation of the wave-changing shaft 18 causes the slide 14, which is coupled to the shaft 18 via pin 16 and member 17, to move in a direction perpendicular to the shaft 18 carrying the coupling member 9 with it. The coupling member is mounted upon a splined portion of the tuning shaft 1 and is thus free to move longitudinally along this shaft but fixed as regards rotation with respect thereto. A toggle action is provided by means of the member 13. In the position shown in Fig. 1 the coupling member 9 co-operates with a pulley member 6, mounted freely upon the tuning shaft 1, so that rotation of the shaft 1 causes rotation of the pulley member and drives the tuning condenser and indicating device 8 for the amplitude-modulation range of the receiver. In the other position of the member 9, Fig. 2, it co-operates with a toothed wheel 22 driving a shaft 19. The shaft 19 is screw-threaded and has mounted thereon a member 26 which moves longitudinally with respect to the shaft upon rotation thereof due to rotation of the shaft 1. The member 26 is connected by a cord 27 to the core of a tuning inductor 28 for the frequencymodulation range. A further cord 23 wound around the shaft 19 and passing over pulleys 24 drives the associated indicator 25.

Title: Improvements relating to the production of alkenyl aromatic compounds
IPC: C08G59/34
Filed: 1960-08-09
Abstract: Epoxy resins are obtained by reacting at least 2 mols of a conjugated diene (which may be cyclic or chlorinated) with 1 mol of an aromatic hydrocarbon in the presence of boron trifluoride or a complex thereof, epoxidising the ethylenically unsaturated aromatic compound obtained and curing, e.g. with phthalic anhydride.  In the Examples (1) benzene is reacted with butadiene to yield a product believed to contain compounds of the formula:  <FORM:0885872/IV (a)/1> which is epoxidized with peracetic acid and cured with 0,85 mol of phthalic anhydride per epoxide equivalent for 6 hours at 120 DEG  C. and 15 hours at 160 DEG C., (2) toluene is reacted with butadiene to yield a product comprising mono- and dibutenyl toluenes and compounds believed to be of the formula <FORM:0885872/IV (a)/2> which is epoxidized and can be similarly cured.ALSO:The reaction of a conjugated diene with an aromatic hydrocarbon to yield an olefinically unsaturated product is effected with a mol ratio of diene to aromatic hydrocarbon of at least 2:1 in the presence of boron trifluoride or a complex thereof.  The aromatic hydrocarbon may be benzene, toluene, xylene, naphthalene, alkylated naphthalene, diphenyl, diphenyl methane or anthracene and the diene butadiene, isoprene, piperylene, 2-methylpentadiene-1,3, pentadiene-1,3, cyclopentadiene, methyl-cyclopentadiene, hexadiene-1,3,1-chloro-2-methyl-butadiene-1,3 or chloroprene, the ratio of diene to aromatic being 2-8:1.  The temperature may be 0 DEG C.-30 DEG C.  In the examples (1) benzene is reacted with butadiene the main product of which is believed to be of the formula <FORM:0885872/IV (b)/1> (2) toluene is reacted with butadiene which is believed to result in <FORM:0885872/IV (b)/2> as well as mono- and di-butenyl toluenes.  Epoxides of the products of the above process are obtained by oxidation, e.g. with hydrogen peroxide in the presence of formic acid or with peracetic acid, perbenzoic acid or monoperphthalic acid, preferably in the presence of chloroform, ethyl ether, methlene chloride, benzene or ethyl acetate as solvent at -20 DEG C. to 100 DEG C.  The product of example (1) is epoxidised with 1.3 mols of peracetic acid for every equivalent of double bonds in the product and the product of example (2) is epoxidised with formic acid and hydrogen peroxide.

IPC: A61K39/02
Filed: 1926-11-10
Abstract: 262,080. Rõth, C. Nov. 24. 1925, [Convention date]. Vaccines and immunizing and like serums; bacteria, cultivating; medicines for internal use.- Chemical compounds of the pyridine or quinoline series capable of influencing the causative microorganisms of disease, as described in Specification 247,965, are caused to act in vitro on cultures of spirochaetae, trypanosomes, cocci, or the like instead of being injected into an animal in conjunction with the micro-organisms. Cultures may be treated with the chemicals or the organisms may be grown on media containing the chemicals. The treated organisms become non- virulent, and if necessary may be further weakened by other means such as heating. The preparations may be used directly for immunizing or curative treatment, or may be injected into an animal, either alone, or in combination with chemicals of the kind described, or with other attenuated or virulent cultures, for the production of immunizing materials which are recovered from the organs or blood of the animal. According to one example, nutrient broth containing a small proportion of the sodium salt of 2-oxy-5- iodopyridine is inoculated with a virulent culture of streptococci and allowed to stand, or the iodopyridine compound may be added 24 hours after inoculation of the nutrient fluid with the virulent culture. According to a second example, washed and centrifuged gonococci are suspended in salt solution and a solution of the iodopyridine compound is then added. The Specification as open to inspection under Sect. 91 (3) (a) relates also to the use, in connection with the present invention or with that of the Specification 247,965, of substances having structural or biological relationships with albumen or its fission products, or capable of developing substances having these properties in the animal organism. This subject-matter does not appear in the Specification as accepted.

Title: Process for resolving dispersions
IPC: C10G33/02
Filed: 1963-07-17
Abstract: Dispersions, for example oil-water dispersions, are resolved by contacting the dispersion with at least two different solids in divided form at the same time, at least two of the solids having under the prevailing conditions a relative electrode potential of at least 1 volt, the several phases being subsequently separated from the solids.  The solid particles may be in the form of a bed.  The particles may be in the form of at least two different classes of particles of which one may be a metal such as iron or aluminium or iron oxide, and another may be a non-metal such as carbon.  At least some of the particles may be such that the surface consists of at least two of the different solids, for example by impregnating one solid with another, or with a compound which will decompose to yield the other solid, for example, carbon impregnated with iron, which may be prepared by impregnating with ferric nitrate and reducing. Alternatively, they may be formed by electrolytically depositing one of the solids on to the surface of particles of one of the other solids, and then abrading so that both solids are exposed.  Thus, the particles may consist of copper and aluminium or iron.ALSO:Particles for resolving dispersions may be prepared by electrolytically depositing a solid on to particles of a different solid having a relative electrode potential of at least 1 volt, and then abrading so that both solids are exposed.  In an example, aluminium granules are plated with copper, using an aqueous solution comprising about 45 grams copper cyanide, 67.5 grams sodium cyanide, 60 grams Rochelle salt, and about 15 grams caustic potash per litre.  Reference is also made to abraded particles comprising iron plated with copper.ALSO:Dispersions, for example oil-water dispersions, are resolved by contacting the dispersion with at least two different solids in divided form at the same time, at least two of the solids having under the prevailing conditions a relative electrode potential of at least 1 volt, the several phases being subsequently separated from the solids.
