Abstract: 1,112,510. Processor stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. 28 Dec., 1966 [3 Jan., 1966], No. 57905/66. Headings G4A and G4C. A data processing system includes at least three storage units and addressing apparatus for addressing the locations of the storage units responsive to a continuous sequence of addresses and arranged to address at least two of the storage units on an individual wrap round basis. The system storage consists of up to four 32K high speed stores HSS and two or more large capacity stores LCS. The large capacity stores LCS may be of a 128K small-sized variety S LCS and/or a 256K large-sized variety L LCS. A single system address gives access to any location in any of the stores used, the HSSs having the lowest addresses and the other stores taking successive groups of higher addresses, except that two LCSs (either both large or both small) may operate in interleaved fashion INTLV, one taking the even addresses in a given range and the other the odd. Also one or more 128K gaps may be left, any attempt to address a location in a gap resulting in an error indication INV ADR. The right half of Fig. 10 shows three example configurations, using one, two and four HSS 8  respectively. Switches are set up in accordance with the storage configuration to cause the system address to be correctly decoded to select the appropriate store and route the appropriate portion of the address to the address register of the selected store to select a word therein. If n is the total number of words in the HSS 8  used, e.g. 32K, 64K or 128K in Fig. 10, the block of the lowest n addresses in each LCS is interchanged with the block of the remaining addresses (wrap round), e.g. in the lowest LCS in the right-most example in Fig. 10, viz. L LCS A, the internal addresses run from 128K to 256K-1 and then from 0 to 128K-1. It is mentioned that two systems with separate HSS 8  might share the same LCS 8 .

Abstract: 1329910 Thermosettable urethane resins MITSUBISHI CHEMICAL INDUSTRIES Ltd 29 Dec 1971 [29 Dec 1970 (2) 20 April 1971] 60569/71 Heading C3R [Also in Division C7] Thermosettable urethane resins are prepared by reacting a product (I), which is obtained by the reaction of one equivalent of an NCO- terminated polyurethane prepolymer and at least two equivalents of a tertiary amine having on average at least three OH groups per molecule with a product (II) which is obtained by the equimolar addition reaction of an organic diisocyanate and a monofunctional blocking agent, in such proportions that 20 to 80% of the OH groups of (I) are reacted with the NCO groups of (II). A resin which is water emulsifiable or water soluble may be prepared by reaction of the above urethane resins with an acid. The prepolymer may be prepared by reacting an organic diisocyanate with a glycol, polyether or polyester, suitably in a solvent. Suitable tertiary amines containing hydroxyl groups are triethanolamine and propylene oxide addition products of ammonia, ethylene diamine, diethylenetriamine and tris-(3-aminopropyl)- amine. The blocking agent used in the production of product (II) may be a phenol, lactam or tertiary alcohol. On reaction with an acid, e.g. acetic acid, cationic urethane resins are produced which may be used in the form of an aqueous solution or emulsion particularly in electrodeposition coating processes. In a typical example toluene diisocyanate is reacted with polypropylene glycol to form a prepolymer which is then reacted with triethanolamine in acetone to form product (I). Product (II) is formed by reaction of toluene diisocyanate and #-caprolactam and is added to product (I) and reacted. The reaction product is added to an aqueous solution of acetic acid to form a cationic urethane resin which is coated on a glass plate and cured by heating.

A device for measuring the angle of rolling contact of radial and end thrust ball-bearings comprises means for determining the travel of the centre of a bearing ball for a given angular movement of a race. The instrument described is particularly applicable to checking the end bearings for gyroscope shafts enabling them to be paired, and comprises a base-plate 11 on which is mounted a support axle 16 for a gyroscope shaft 20, the gyroscope wheel 21 being shown chain-dotted. A bearing 24 is mounted on the shaft 20 as under service conditions, being axially loaded by a cap 35 seated on the outer race 27. The cap 35 is steadied for rotation about the axis 16 by rollers 45 and its rotations are recorded by a counter 55. The cap 35 is lowered gently on to the race 27 by a screwed ring 52 previously raised to ensure that the cap would not initially contact the race. A member 85, having a pointer 86 secured to it, is engaged with the cage 26 of the bearing and rotates with it. In the absence of a cage the member 85 is designed to engage the bearing balls. The cap, and thus the race 27, is given a predetermined number of rotations, and the angle of rolling contact, being a function of the consequent revolutions of the cage 26, is read off from the pointer 86.
