Title: Stabilization of nuclear chlorostyrenes
IPC: C07C17/42
Filed: 1946-09-06
Abstract: The polymerization of polymerizable nuclear chlorinated (especially dichlorinated) styrenes during distillation is inhibited by conducting the distillation in the presence of an effective amount (i.e. from less than 0.01 per cent upwards, preferably about 0.1 per cent) of a nitrosophenol.  When distilling nuclear dichlorinated styrenes from reaction mixtures containing them, using a fractionating column or reflux condenser from which reflux condensate is returned to the distilling zone, it is advantageous to employ 1-nitroso-2-naphthol as inhibitor and to add it, preferably in solution in purified dichlorostyrenes, to the reflux condensate, an example being given of this procedure.  p-Nitrosophenol is also particularly effective as an inhibitor, and others specified are nitrosothymols, nitrosocresols, nitrosoresorcinols, nitrosocatechols, nitrosopyrogallols and halogen-substituted nitrosophenols.ALSO:The polymerization of polymerizable nuclear chlorinated (especially dichlorinated) styrenes is inhibited by incorporating therewith an effective amount (i.e. from less than 0.01 per cent upwards, preferably about 0.1 per cent) of a nitrosophenol.  In examples: (1) a mixture of crude dichlorostyrenes produced by dehydrochlorination of chloroethyldichlorobenzenes is distilled in the presence of 1-nitroso-2-naphthol; (2) p-nitrosophenol, 5-methyl-3-isopropyl-4-nitrosophenol and 1-nitroso-2-naphthol are added to separate portions of mixed nuclear dichlorostyrenes, and the products are tested for resistance to polymerization in a test tube immersed in boiling water; (3) a mixture of nuclear dichlorostyrenes containing 1-nitroso-2-naphthol is stored at 20 DEG  C.  Other inhibitors specified are: nitrosocresols, nitrosoresorcinol, nitrosocatechols, nitrosopyrogallols and halogen-substituted nitrosophenols.

Title: Secondary acyloxy compounds
IPC: A61K31/22
Filed: 1976-06-29
Abstract: There are prepared novel secondary acyloxyamines of the formula <IMAGE> in which Z1 represents hydrogen or acyl and Z2 represents acyl, where acyl denotes the radical of an aliphatic, cycloaliphatic, aromatic or araliphatic carboxylic acid, and R1 represents an optionally substituted aliphatic, cycloaliphatic or araliphatic hydrocarbon radical, or their salts. These compounds are obtained in a manner known per se by esterification of corresponding hydroxyamines. The novel compounds in particular have cardioselective  beta -receptor-stimulating actions of a long duration of action. The novel compounds thus have a positive chronotropic and in particular a positive inotropic action. These pharmacological activities characterise the novel compounds as cardiotonics, which can be used alone or in combination with other compounds having cardiovascular activity, e.g. cardiac glycosides, in the form of pharmaceutical preparations for the treatment of myocardial insufficiency.

Title: Door latch
IPC: E05F5/08
Filed: 1964-06-30
Abstract: 1,026,995. Door latches. H. NEVELING. June 30, 1964 [July 27, 1963], No. 27031/64. Heading E2A. A door latch comprises a pivotable latch bolt 15 coupled to a rotary cam 12 having an over centre position, and an energy storage means 6 including a rectilinearly guided driving member 8, 9 within which the cam is rotatable and which acts as a follow to the cam. The door latch comprises a damping cylinder 4 filled with oil and accommodating an axially movable piston 5 and a spring 6 which serves as an energy storage means. The spring surrounds a piston rod 8 one end of which projects into a sliding member 9. A pivot 10 supported in a lock case 2 passes through slots 11 in the sliding member to ensure rectilinear movement thereof and has an eccentric disc 12 rigidly mounted thereon. The pivot also carries a latch bolt 15, shown in the unlatched position in Fig. 4, the latch bolt being held in this position by the over-centring of the eccentric disc 12, the sliding member 9 being held in the lifted position. When the door is closed the latch bolt 15 strikes a nose on the locking plate (Fig. 5, not shown) and pivots the eccentric disc back from its over-centre position so that the sliding member under the action of the spring can further pivot the eccentric disc and thus the latch bolt 15. The closing movement of the door is damped by the piston 5.

Abstract: 854,157. Multifocal lenses. PITTSBURGH PLATE GLASS CO. Aug. 22, 1958 [Oct. 7, 1957], No. 27036/58. Class 97(1) [Also in Group XXIII] A method of forming fused trifocal lens blanks having a major portion with a countersink therein, an intermediate portion and a reading portion, comprises forming a countersink defined by two intersecting surfaces of different radii in a major portion blank, mounting said blank with its countersink upwards and pouring molten glass, having a different refractive index from that of the blank, into said countersink to fill it. In the method described, a countersink C (Fig. 1) defined by two surfaces I and R of different radii is formed in a major blank M of glass of one composition The blank is mounted in a support 12 (Fig. 7) with the countersink inclined to the horizontal; the blank is then heated and molten glass G of another composition is poured on top of the countersink so that it flows down, fills the countersink and overflows. The flow is then cut off by shears 13 and the lens blank is removed. Alternatively the maior blank may be mounted with the countersink horizontal (Fig. 11) and the support 12A moved transversely beneath the stream of molten glass G. The shear scars e.g. S<1> are arranged to be on that part of the lens blank which is subsequently ground to form the lens.

Rolling tubes; die-rolling.-Hollow bars, particularly for use as rock drills, are rolled while on their mandrels in profiled rolls 6 having wide entering grooves 9 to receive the shank end and grooves 12 of reduced or tapering section to form the stem portion of the drill. The mandrel, which is preferably of ductile metal, is withdrawn after the rolling operation. The stem may be formed of different section from the shank. The work is introduced along a grooved guidetable 13 so as to contact with an adjustably pivoted gauge 17 which yields against the resistance of a spring 18 when the work is fed by the action of the rolls. The grooves in the rolls may be formed to produce two rock drills which are subsequently parted.

Title: Glass ceramic bodies and method of making them
IPC: C03C3/062
Filed: 1963-07-15
Abstract: A thermally-crystallizable glass composition consists essentially of 10-20% Na2O, 1-20% BaO, 28-38% Al2O3, 30-55% SiO2 and 5-12% TiO2 by weight.  A glass-ceramic body may be made therefrom by exposing a glass of the above composition to 1000-1160 DEG  C. Preferably, a batch containing the requisite constituents is melted, then simultaneously shaped and cooled to below the point of transformation to an amorphous solid, then heated to about 780-800 DEG  C. for 1-5 hours to initiate nucleation, and then heated to 1060-1160 DEG  C. for 1-8 hours.  The transformation point is at about the annealing point, viz. 700-725 DEG  C.  During cooling and shaping, the body may be cooled to room temperature for inspection and decorating before the heat treatment.  The articles may be heated to the nucleation temperature at 5 DEG  C. per minute. Alternatively, the body may be heated at constant rate from room temperature or transition point to 1000-1160 DEG  C. for, e.g., 1-24 hours.  During the treatment at 1000-1160 DEG  C., crystallization of nepheline (Na2O. Al2O3.2SiO2) and celsian or hexacelsian (dimorphs of BaO.Al2O3.2SiO2) occurs.  A fining agent, e.g. As2O3, may be added to the glass batch; up to about 1% may be used.  The bodies have high modulus of rupture, high resistance to thermal shock, high resistance to abrasion, accept and retain a glaze, and are resistant to staining by foods and to the action of detergents. The melt may be shaped by conventional methods, e.g. pressing, blowing, casting, drawing, rolling or centrifugal casting. Specification 829,447 is referred to.
