Title: Slide fastener
IPC: A44B19/40
Filed: 1971-12-22
Abstract: 1316538 Slide fastener E BEITTER 22 Dec 1971 [22 Dec 1970] 59819/71 Heading E2S A sliding clasp fastener is formed of continuous filament coupling elements 2 attached by means of thread loops or of welds to carrier elements 1 consisting of a continuous, bend resistant wire in the form of a uniform sequence of meander portions or loops, which may take various forms e.g. the loops may overlap or be of figure of eight shape, and be interconnected by welds. The limbs of the carrier element may have recesses 16 in which lie loops of the fixing thread by means of which the fastener is attached to an article. To vary rigidity, thread or plastics wire may be fixed across the limbs of the carrier element. The loops may be bent either at right angles to, or in, the plane of the carrier elements. The fastener is produced by simultaneously securing the coupling elements of a row to the wire forming the carrier element, and banding this wire to its final shape. A carrier element may be attached to a strip of film material which is then sewn to the article, or the fastener may be attached to the article by means of fixing threads sewn across the carrier loops and parallel to the fastener element or of stitches near the rearward curved ends of the carrier element.

Abstract: 1,235,058. Ceramic pigments. TH. GOLDSCHMIDT A.G. 12 Dec., 1969 [25 Jan., 1969], No. 60828/69. Heading C1M.  A stanniferous ceramic pigment is produced by calcining stannous oxide and a mixture comprising compounds containing antimony and vanadium, said compounds being present in quantities that will provide up to 10% by weight of each of antimony and vanadium oxides in the pigment. The calcination is preferably in two steps and between 900 and 1400‹ C. The stannous oxide may be present in the starting material in an amount of 50-95% by weight. The antimony-containing compound may be Sb 2 O 3  or Sb 2 O 5  and the vanadium compound ammonium metavanadate (NH 4 VO 3 ). Silica and zirconia may also be present in the pigment. The pigments normally give a greyish colour after incorporation in a colourless glaze but chromium oxide may be added to give a green-grey colour.

Abstract: 1,253,321. Mercapto group protection. MERCK & CO. Inc. 15 Dec., 1969 [19 Dec., 1968], No. 61012/69. Heading C2C. [Also in Division C3] Mercapto groups of cysteine or cysteinecontaining peptides are protected by a R.CONHCH 2 - group (where R is alkyl or aryl) by reaction with an N-hydroxy-methylalkyl amide or an N-hydroxyarylamide in the presence of an anhydrous acid e.g. HF, F 3 C.COOH, Cl 3 C.COOH or Cl 2 CH.COOH. The blocked cysteine or cysteine containing peptide may be used as a reactant in a peptide synthesis e.g. in a synthesis of oxytocin.

Title: Channel identification apparatus useful in a sweep tuning system
IPC: H03J7/20
Filed: 1980-05-29
Abstract: A channel identification apparatus for a TV receiver includes a memory 37 for storing binary signals representing boundary voltages having magnitudes corresponding to magnitudes of the tuning voltage between tuning voltage ranges for respective adjacent channels. As the memory locations at 37 are addressed, the boundary voltages are compared 49, 55 to a tuning voltages. Control apparatus 41 causes the memory location associated with the next boundary voltage to be addressed and causes channel number apparatus 43, 45 to generate binary signals representing the next channel number when the magnitude of a predetermined one of the boundary voltage associated with an addressed one of the memory locations and the tuning voltage exceeds the magnitude of the other one. Display apparatus 59 such as LED's displays the channel number represented by the binary signals generated by the channel number apparatus. Because the boundary voltages are utilized, the channel identification apparatus described is particularly suited for use in a signal seeking or manual tuning system. <IMAGE>
