Title: Musical Instrument
Inventor: JEFFERY ALBERT WILLIAM
IPC: G10D3/06
Filed: 1967-04-14
Abstract: 1,181,992. Electrophonic musical instruments. A. W. JEFFERY and E. H. ANDREWS. 12 July, 1968 [14 April, 1967], No. 17366/67. Heading G5J. A finger board 1 for a stringed musical instrument is equipped with a plurality of longitudinally extending slots 2 in its face presented towards the strings for the reception of electrical wiring and/or components. Laterally extending frets 3 are also provided, which may act as the electrical contacts for the strings. In this case the frets must be made from metal or plastics material capped with metal, and are put in place before slots 2 are cut and arranged so that the action of cutting separates the fret into electrically isolated sections, each disposed beneath one string. The wiring can be laid in slots 2, the slots then being plugged by strips of veneer and ground to lie flush with the top surface (Fig. 4, not shown). In a further embodiment (Fig. 5, not shown) a smaller number of deeper slots 2 is incorporated, the wiring for each string being stacked in the available slots, and insulated from one another by material such as plastic wood. Figures 6 to 20 (not shown) illustrate a method of manufacture of a finger board according to the invention and shows several ways of attaching the wiring and/or components to the string contacts on the upper surface. One by direct soldering (Fig. 11), one by welding a tinned metal strip to the contact and attaching the components thereto by soldering (Fig. 12) and one in which a soldered joint is made between two components, a blob of solder being left on the joint in such a position that it is sawn in two when the fret slots are cut, the fret section then being inserted between the two halves of the solder blob and heated to fuse the solder to the fret. As an alternative to using the fret as a string contact, T-shaped pieces of brass are inserted into slots 2, leaving sufficient space beneath the brass for wiring (Fig. 15). In this latter case, the fret may be made of any suitable material (not necessarily electrically conductive).

Abstract: 1446965 Treatment of legumes AGRICULTURAL PRODUCTION & VEGETABLE PRODUCTS Ltd 4 Feb 1975 [14 Feb 1974 19 April 1974] 6843/74 and 17373/74 Headings A2B and A2E [Also in Division C3]  A food product comprises legume material wherein at least some of the starch has been degraded, and is in the form of a bland waterdispersible powder containing up to 90% protein. In a preferred method of making the product, an aqueous slurry of ground or flaked legume material is treated at pH 8 or less with an amylolytic enzyme e.g. at 40-100‹C for 2- 120 mins., to liquify and hydrolyse the starch therein to dextrins. The legumes may be heat treated before the enzyme treatment to gelatinise the starch and inactivate toxins, and may be allowed to germinate to eliminate oligosaccharides. The aqueous liquid in the slurry may be whole, skim or separated milk, whey, or waste aqueous liquid from meat, fish, cereal or vegetable processing. The legume should contain at least 15% protein and 35-75% starch (dry basis) and may be of the genus Phaseolus, Pisuin, Lens, Cicer, Cajanus, Canavalia, Vigna, Dolichos, Lupinus, or Vicia. The enzyme may be α-amylase and/or amyloglucosidase. 4 to 90% of lipid material e.g. tallow, lard, poultry fat, marine oil, coconut palm, palm kernel, soybean, maize, arachis, sunflower seed, safflower seed, rape seed, cotton seed, or linseed oil, may be added. A sulphur containing amino acid e.g. methionine may also be added. A free flow agent or dessicant, an emulsifier, vitamins, minerals and aldehydes may also be included. The treated legume may be used in milk replacer compositions for young ruminants, infant foods, or dietatic foods. In a variation of the process a portion of the slurry may be separated out before amylolytic enzyme treatment, optionally subjected to proteolytic enzyme treatment, and then recombined after the amylolytic enzyme treatment. Cellulose, hemicellulose and/or pectinase may also be added to degrade cell wall materials and reduce the content of raffinoses and sucrose. Aldehyde may be added in order to combine with the protein to form a product soluble at pH less than 4 and insoluble at pH greater than 5.

Patent GB-674299-A (GB)
Title: Manufacture of compounds of the androstane series
IPC: C07J1/00
Filed: 1950-07-12
Abstract: Compounds of the androstane series are manufactured by treating a 3-hydroxy-20-ketopregane with an aromatic per-acid in the absence of an esterifying agent, and either in the absence of an acid catalyst at a temperature below about 30 DEG  C. or in the presence of an acid catalyst, and, if desired, subjecting the product to fractional separation or to further oxidation, or both. The starting materials may contain nuclear double bonds (e.g. in the 5 : 6 or 11 : 12 position), these preferably being temporarily protected (e.g. by the addition of halogen or hydrogen halide which are subsequently split off again).  Further substituents (e.g. a free or substituted hydroxy or keto group in the 11-position) may also be present.  The nature of the products obtained depends on the reaction conditions.  In the presence of an acid catalyst (e.g. sulphuric, perchloric or p-toluenesulphonic acid) the per-acid merely oxidizes the -COCH3 group in the 17-position to -OCOCH3, the 3-hydroxy group being, if desired, subsequently oxidized to a keto group (e.g. by means of a metal alcoholate or phenolate and a carbonyl compound, or chromium trioxide or permanganates).  In the absence of an acid catalyst, oxidation of the 3-hydroxy group is the main reaction, but some oxidation of the 17-acetyl group occurs as an alternative or concurrent reaction, giving a mixture of three products which may be separated into ketonic and non-ketonic fractions and the former further fractionated by hydrolysis, chromatography and crystallization.  In examples: (1) pregnenolone is brominated in carbon tetrachloride, oxidized with monoperphthalic acid in the presence of p-toluenesulphonic acid, and debrominated with zinc dust and glacial acetic acid, producing D 5-androstene - 3b  : 17b  - diol 17 - monoacetate; (2) the oxidation in (1) is effected with perbenzoic acid in the absence of a catalyst, and progesterone, and testosterone are isolated from the hydrolysis product of the ketonic portion and D 5 - androstene - 3b  : 17b  - diol 17 - monoacetate from the non-ketonic portion of the reaction product; (3) D 5 : 6-14-allo-17-isopregnene - 3b  - ol - 20 - one is brominated and oxidized as in (2), further oxidized with chromium trioxide in glacial acetic acid, and debrominated, giving D 4 : 5-3-keto-17a -acetoxy-14-alloandrostene (which is converted by the action of methanolic caustic potash to 14-allo-17-epitestosterone) and 14-allo-17-isoprogesterone.
