Title: Improvements in or relating to metallic oxide rectifiers
IPC: H01L29/24
Filed: 1930-02-24
Abstract: 336,926. Siemens - Schuckertwerke Akt.-Ges. Feb. 27, 1929, [Convention date]. Electrodes. - Leads are attached to metallic oxide rectifiers in which the oxide is coated with a sprayed-on layer of metal by soldering. The oxide layer is coated with graphite and the graphite coating and the lead are smeared with soft solder in a pasty condition to which is added an acid-free deoxidizing agent, such as powdered colophony, to which may be added powdered salammoniac. Zinc is then sprayed on to the oxide layer so as to form a metallic coating and at the same time melt the solder and thus form a joint. The solder may consist of equal parts of tin and lead, or may also contain bismuth.

Title: Improvements relating to the decoration of glass and ceramic sheets, tiles and other products
IPC: C03C17/02
Filed: 1937-03-02
Abstract: 491,562. Enamelling and glazing. PARKINSON, F. D. March 2, 1937, No. 6220. [Class 56] A method of providing glass or ceramic sheets, tiles, or other articles with mottled, marbled, crinkled, or patterned surfaces consists in coating the whole or part of the article, which has been chemically cleaned, with a film of waxy, greasy, or resinous nature, and then applying a suspension of powdered enamel, glaze, glassy solids or stains in a liquid which is not miscible, or only slightly so, with the film so that drops of the liquid coalesce into patches or distribute themselves more or less evenly. The article is then fired to volatilize the film and fuse the suspensions. The film may consist of shellac, canada balsam, essential oil, or natural or artificial resins, all in appropriate solvents, or waxes emulsified in water, and it may be applied by brushing, stippling, spraying, or printing as by means of transfers. The suspension may be applied by brushing, pouring, or spraying. The effect produced may be altered in various ways, for example, by varying the extent to which the surface is coated by the film, variation of the particle size or fusibility of the powdered enamel or glaze, or variation of the volatility of the liquid in which the enamel is suspended. Repeated coatings and firing may be used to obtain a multi-colour effect, and the film may be applied in a pattern.

C. ; 4618, Lafayette Avenue, Merchantville, New Jersey, U.S.A.) Feb. 26, 1934, No. 6237. [Classes 39 (i) and 40 (v)] A valve comprises screening means screening the main anode from an auxiliary anode and from the control grid, and adapted upon variations of the potential of the screening means to vary the mutual conductance between the control grid and main anode whilst producing only a negligible change in the mutual conductance between the control grid and the auxiliary anode. The screening means may be located clear of the path between the cathode and the main anode. In one form, Fig. 1, a valve comprises a cathode 8, a control grid 10 and a main anode 13 and auxiliary anode 12. Either anode may be made of mesh or of sheet-metal. The screening means 19 comprises a grid structure 20, an outer screen structure 21 and a connecting perforated plate 22. The grid portion 20 is closed by a cap 23. The valve may be connected in circuit as shown in Fig. 2 in which a signal input circuit 32 is connected to the control grid 26, and an output circuit 33 to the main anode 27. The auxiliary anode 28 is connected to a circuit including a coupling coil 36 and a high resistance 38 maintaining constant current. The screen 29 is connected to a variable tap 39 so that its grid portion 30 alters the mutual conductance of the main anode circuit. In a modification, the input circuit is connected to a second control grid interposed between the screen portion 30 and the main anode ; a second screen is then interposed between this control grid and the main anode and is connected to the screen structure 29. Reference has been directed by the Comptroller to Specification 408,328.
Patent GB-740319-A (GB)
Title: Process for the direct resolution of dl-threonine
IPC: A61K31/195
Filed: 1954-03-03
Abstract: Threonine is resolved into its optically active forms by dissolving enough DL-threonine in water or aqueous alcohol at an elevated temperature to produce a solution which is supersaturated at room temperature, adding to the hot solution a small amount of one of the active forms and cooling to effect crystallization of the active form.  The mother liquor may be heated and further DL-threonine added, whereby the other active form crystallizes on cooling.  This process may be repeated indefinitely.  In a modification the DL-threonine is used in part as a soluble acid-addition salt such as the hydrochloride, the mixture of base and salt being obtained either by partial acidification of free threonine or partial addition of an inorganic or organic base to a threonine salt.  The amount of active form added to start the process may be 2-12 per cent by weight of racemic form.  The solution is preferably cooled through a range of 20-60 DEG  C., the crystallization temperature being 20 DEG  C. or below.  The crystallized threonine can be freed from any DL-form present by recrystallization.  The D(+)-form may, if desired, be converted into the more valuable L(-)-form.
