Filed: 1972-11-29
Abstract: 1413665 Overhead power conductor REYNOLDS METALS CO 20 Nov 1972 [9 Dec 1971] 55171/72 Heading H1A In an overhead power conductor comprising a steel core 12 and an aluminium or aluminium alloy component 14 around the core the aluminium component is at least partially annealed and has a yield strength below 8500 p.s.i. for 0À2 elongation. As shown the aluminium is preferably stranded about the steel core, the aluminium wires being annealed before stranding. The conductor is stressed above its normal working load before or during erection so that the aluminium component is inelastically stretched and so that most or all of the normal load will be borne by the steel core as opposed to prior conductors in which the aluminium component is hard tempered and bears a significant proportion of the tensile load. The conductor is thus less susceptible to creep, say, and loss of strength due to overheating and various modes of vibration. The aluminium preferably has a capacity for ductile inelastic extension of at least 5% in ten inches and a conductivity of at least 61% IACS. The steel core may be galvanized or aluminized and the aluminium component may be in the form of a seamless or welded tube or made up of sector-shaped component or of flat conductors having rounded edges.

Abstract: 1,253,987. Electroluminescence. T. G. KMITA, I. V. RYZHIKOV, V. I. RYKALIN, and V. I. PAVLICHENKO. 3 Dec., 1968, No. 57327/68. Heading C4S. [Also in Division H1] A diode pulse source of light consists of a silicon carbide crystal provided with a sharp PN junction, the N-type bulk having a donor concentration in the range 8À10<SP>17</SP>-5À10<SP>18</SP> atom. cm.<SP>-3</SP> and also having a luminescence activator (acceptor) in the concentration range 5À10<SP>17</SP>- 8À10<SP>17</SP> atom.cm.<SP>-3</SP>, non-significant impurities being kept below 2À10<SP>17</SP> atom.cm.<SP>-3</SP>. The embodiment described has a nitrogen and aluminium-doped crystal to which siliconaluminium is alloyed to form a P-type region and associated contact. A nickel-coated tungsten annulus is welded to the other face of the crystal to provide an ohmic contact. Rare earth metals (e.g. Gd, Dy &c.) may replace aluminium as the activator (and are also acceptors). Carbon-particle inclusions in the carbide act as emission localizing centres and give enhanced output. Though the diode is normally used with forward bias and emits at 450 mÁ. with Al and N, in the presence of carbon inclusions it may be operated under Zener breakdown to emit blue light. The quantum efficiency of the device varies with Al and N concentration and with the content of impurities such as Ti, Fe and Ni.

Title: Memory system
IPC: G11C29/00
Filed: 1968-12-05
Abstract: 1,207,560. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 5 Dec., 1968 [17 Jan., 1968], No. 67761/68. Heading G4C. In a memory system, a main and an auxiliary memory are simultaneously accessed, and the output of the auxiliary memory is scanned to determine if there is a bad bit in the word accessed from the main memory and provides the location of the bad bit and the corrected bit for the main memory word. An address having word and block portions (a block being 32 words) is used for accessing a word in main memory and the block portion is used to access, in an error control memory, a word corresponding to the block. This latter word contains sub-words and is inserted into an associative memory. Each sub-word specifies the word portion of the address of a main memory word in the corresponding block which contains a bad bit (faulty storage element), the address of the bad bit within the word, the value of the bit, and two flag bits. The word portion of the address used for accessing the main memory is matched associatively against the word portion, in each sub-word in the associative memory, and each sub-word giving agreement corrects the appropriate main memory bit in the main memory read-write register. Thus more than one bit can be corrected in each main memory word. A subword in the associative memory is only used if both its flag bits are 1 (this facility permitting the error control memory to contain bad bits)

Abstract: 1355587 Pipe couplings R & G SLOANE MFG CO Inc 22 Dec 1971 [20 Jan 1971 15 April 1971] 59626/71 Heading F2G [Also in Division C4] In a tell-tale arrangement for indicating failure to effect adhesive bonding between two surfaces, both surfaces are coated with material containing an adhesive and a separate colour precursor compound for each surface, so that a contrasting colour is produced, only when the surfaces are contacted with the or each adhesive coating in a bondable condition. The contrasting colour may be produced by a change of pH using an indicator such as phenolphthalein, thymol blue or nitramine. Alternatively, it may be produced by a colour generating reaction between components such as an amino acid and ninhydrin or between a diazo base and a phenolic coupler. Examples are given of joining P.V.C. pipe sections (the outer of which may be transparent and colourless) by means of a solvent cement solution of P.V.C. in tetrahydrofuran. Primer solutions contain, respectively, the diazo base and the phenolic coupler dissolved in tetrahydrofuran. Colour is developed within a minute of uniting the correctly primed surfaces by means of the cement. Besides the common diazo bases, the borofluoride or zinc chloride salts of the following may be used; 4-diazo-2,5-diethexyphenyl morpholine, 4-diazo phenyl morpholine and p-diazoo-chloro-N,N<SP>1</SP>-diethyl aniline (BF 4 , only). Phenolic couplers include 3,5-resorcylic acid ethanolamide and 4-bromo-3,5-resorcylic acid. An alkyl amine is added either to one of the primers or to the cement as an alkaline buffer.

Title: Multi-channel Sound Systems
IPC: H04H20/88
Filed: 1978-10-10
Abstract: In Multi-channel Sound systems for cinemas, left and right channel signals are conventionally matrixed with a surround signal to form two signals which are recorded on a stereo bilateral variable area sound track. On playback the original signals are recovered by a matrix decoder 12. The left and right signals LF and RF (and optionally a derived centre signal CF) are applied to respective loudspeakers. The surround signal feeds loudspeakers at the back of the cinema but is delayed (delay 22) by about 75% of the sound path length from front to rear of the auditorium. This suppresses perceived cross-talk from the left and right signals to the surround loudspeakers. <IMAGE>
