Title: Memory and buffer arrangement for digital computers
IPC: G06F12/08
Filed: 1975-04-01
Abstract: 1488980 Memory accessing XEROX CORP 1 April 1975 [1 April 1974] 13230/75 Heading G4A A computer includes a central processing unit 10, Fig. 1, a random access memory 11, a buffer 16 and a cache 12, the cache 12 having less storage space but higher access speed than the buffer 16 and the buffer 16 having less storage space but higher access speed than the memory 11, each word stored in cache 12 and buffer 16 being associated with the address of the word in memory 11; a read request from central processing unit 10 causes the address, in memory 11, of the requested word to be supplied to cache 12, buffer 16 and memory 11 in turn until the requested word is found and read out to unit 10, the word also being entered in the cache 12 or in the buffer 16 and cache 12 when it is found in buffer 16 or memory 11 respectively. A write request from unit 10 causes the respective word to be written in buffer 16 for subsequent transfer to memory 11 and also causes the cache 12 not to respond to the next read request for that word, so that the updated word from buffer 16 is read. Words may be transferred from the memory 11 to the buffer 16 and cache 12 and from the buffer 16 to the cache 12 in blocks each of four words. Each word is stored in the cache 12 in a location 20, Fig. 3, associated with the corressponding address stored at 21, 22, identity of the stored address and the address, from the central processing unit, of a desired word, being indicated by a compare circuit 24 to enable, in response to a read request on line 13R from the central processing unit, gates 25. Counters 30 and 31 determine which word location is written into every time a word is read from the buffer to the cache. The counter 30 is set to a predetermined count when a word is written in the corresponding word location and is decremented by one every time this word is read. When the count in counter 30 reaches zero the cache does not respond to the next read request for that word but forces a read request to the buffer in case the buffer has been updated by a separate processor 10a, Fig. 1, and to prevent the word being overwritten in the buffer, by updating a recency of usage counter therein. The counter 30 is also reset to zero if a write request is made for the corresponding word, the corresponding word location then being available for storage. If none of the counters 30 contains a count of zero the least recently used word location, as represented by the counts in counters 31, is used for storage. In the buffer 16 respective recency of usage counters (61, Fig. 4, not shown) determine which storage location is to be written into for any storage operation respective flip-flops (80) preventing overwriting of a word written into the buffer 16 from the central processing unit 10 until that word has been transferred to the memory 11.

Abstract: 904,342. Measuring electrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 31, 1960 [April 17, 1959], No. 13263/59. Class 40 (1). [Also in Group XL (c)] In an extensometer the two components 5 and 3, Fig. 1, of a coaxial line are attached by lugs 4 and 2 to the points between which it is required to measure the strain or extension. Relative movement of the coaxial line components changes the resonant frequency of the line which changes can be detected either by feeding a variable frequency signal into the line or loop 13 and finding the frequency at which the line absorbs the maximum power or alternatively making the line the frequency determining circuit of a squegging oscillator and receiving the output signal on a calibrated tunable receiver. In the latter case the oscillator may be built into an extension of the line casing as shown in Fig. 3 (see Group XL (c)).

Title: Improvements in or relating to the polymerization of olefins and catalysts therefor
IPC: C08F10/00
Filed: 1957-04-29
Abstract: Catalysts suitable for olefin polymerization reactions (see Group IV (a)), are prepared by depositing an oxide of titanium, zirconium, thorium or hafnium on alumina, in the absence of any compound of a metal of Group Va, VIa, VIIIa or VIII, and then contacting the deposited oxide with hydrogen at at least 500 DEG  C. The oxide is preferably deposited on the alumina by impregnating the alumina with a solution of the corresponding alkoxide in an organic solvent and then hydrolysing the alkoxide to form the oxide.  Other compounds yielding the oxide on hydrolysis may be used in place of the alkoxide, e.g. the metal chloride, nitrate, sulphate, acetate, or propionate.  Part, but not all, of the alumina may be replaced by an inert carrier, e.g. silica.  The hydrogen may be admixed with an inert diluent, e.g. helium or argon.  It may be used at atmospheric pressure for a period of 4 to 40 hours.ALSO:Olefines such as ethylene and propylene, their homologues, and styrene are polymerized in the presence of a catalyst (see Group III) obtained by depositing one or more Group IVa metal oxides on alumina, in the absence of any compound of a Group Va, VIa, VIIa or VIII metal and treating the product with hydrogen at at least 500 DEG  C.  Part of the alumina may be replaced by an inert carrier, e.g. silica.

Title: Manufacture of condensation products containing halogen
IPC: C07C37/20
Filed: 1930-05-03
Abstract: Compounds containing halogenmethyl groups are obtained by causing an aqueous formaldehyde solution saturated with gaseous hydrogen halide to react with phenol or a homologue thereof.  The products obtained may vary with the conditions, thus when phenol or a technical cresol mixture is added rapidly at a moderate temperature to a formaldehyde solution saturated with hydrogen chloride, resinous products which are probably mixtures of chlormethyl compounds are obtained, but if phenol is introduced slowly at a low temperature a crystalline compound having probably the following constitution <FORM:0347887/IV/1> is the principal product.  o- and p-cresol under similar conditions yield respectively 2-oxy-3 : 5-di-(chlormethyl)- and 4-oxy-3 : 5- di(chlormethyl)-toluene.  Examples of the preparation of chlormethyl derivatives from phenol, p-cresol, and the technical cresol mixture, are given.  The products are intermediates for the preparation of dyestuffs, synthetic resins, tanning materials and auxiliary products for use in dyeing.  They reset with phenols with elimination of hydrogen halide to yield resins, and yield basic substances when treated with secondary bases.  With pyridine water-soluble products, which are probably quaternary ammonium compounds, are obtained.  Specifications 17118/99 and 12421/01 [both in Class 2, Acids and salts, Organic &c.], are referred to.
