Abstract: 920,912. Electronic digital computors. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 21, 1961 [March 21, 1960], No. 10208/61. Class 106 (1). Where a number of data input/output facilities, such as transducer arms 10 to 12 of a multidisc random access store 41, 42, 44, are associated with a data processing machine, an instruction asking for any available facility causes (a) an examination of the state of reservation latches, one for each facility which if set indicates that its associated facility is busy, and (b) the entry in the instruction register 14 of the address of an available facility, or, when all are busy, the initiation of a new instruction cycle. The instruction may alternatively ask for a particular facility and if this is busy a new instruction cycle is started. In instruction register 14, digit 4 specifies one out of three transducer arms 10 to 12 associated with each set of storage discs 41, 42 and 44, digit 5 specifies a set of discs, digits 6 and 7 specify a disc and digits 8 and 9 specify a track of a disc.

Patent GB-755926-A (GB)
Title: Process for the purification of acrylic acid nitrile
Filed: 1952-04-23
Abstract: Acrylic acid nitrile, obtained as a dilute aqueous solution by absorption in water of the gaseous mixture issuing from the reaction tower used in the synthesis of acrylic acid nitrile from hydrogen cyanide and acetylene in the presence of an aqueous cuprous salt catalyst, is purified by a process comprising bringing it into contact with an organic solvent.  The dilute solution contains 1-2 per cent of acrylic acid nitrile and divinyl acetylene as impurity with or without other compounds. The solvent used is one for which the distribution coefficient of acrylonitrile in the solvent/water system is small and that of the divinyl acetylene is large.  Solvents which are suitable are those having no, or very slight, dipolar properties, e.g. benzine hydrocarbons; unitary hydrocarbons such as pentane, hexane and octane; mixtures of hydrocarbons such as petroleum ether or light benzine; halogenated hydrocarbons such as trichlorethylene, tetrachlorethane and tetrachlorethylene; aromatic hydrocarbons such as benzene, toluene and xylene; hydrogenated hydrocarbons of the benzene or naphthalene series such as cyclohexane, tetraline or decaline and halogenated hydrocarbons such as chlorbenzene and orthodichlorobenzene.  Further compounds such as ethers, esters and ketones may be used only if their dipolar character is weakened by large hydrocarbon residues.  Mixtures of these solvents may also be used.  The process may be carried out continuously or otherwise.  In the discontinuous process the aqueous acrylic acid nitrile solution containing impurities is agitated with the solvent, e.g. petroleum ether.  The impurities, e.g. divinylacetylene, chloroprene and cyanobutadiene, are dissolved in the petroleum ether.  The aqueous layer is separated and the acrylic acid nitrile may be obtained by azeotropic distillation.  The continuous process is carried out on the counter current principle and several contains connected in series may be used.  In the examples: an aqueous solution of acrylic acid nitrile obtained from the reaction between hydrogen cyanide and acetylene in the presence of an aqueous cuprous salt is purified by treating it with (a) hexane, (b) petroleum ether, (c) benzene, and (d) tetrachlorethylene.

Title: Improvements in hydraulic testing machines
IPC: G01N3/36
Filed: 1932-04-11
Abstract: 400,171. Testing physical qualities ; indicating-mechanism. AVERY, Ltd., W. & T. and COX, H. N., Soho Foundry, Birmingham. April 11, 1932, Nos. 10262, 10263, and 10264. [Classes 106 (ii) and 106 (iv).] A hydraulic testing-machine includes a differential ram responsive to the testing pressure and operating an indicator through a compound lever system. Means for automatically indicating the maximum pressure attained and for maintaining a constant pressure are also included. The pipes 14, Fig. 1, connecting an electric pump 15 to the cylinders 6 communicate with a differential ram 17 that operates a pointer 32 through a system of levers. The lever 21 has alternative fulcra 22, 24 brought into action by fixing or releasing by means of an arm 31 a lever 23 supporting the fulcra, thus varying the range of pressure, the dial 27 having two scales 27a, 27b, the pointer 32 co-operating with both. The pointer 32 carries a contact 32b, Fig. 3, which moves an auxiliary pointer 33 as the pressure increases. The contact 32b also closes an electric circuit to hold off a spring brake 39. When the pressure falls the contact opens and the brake 39 holds a disc 40 on the pointer 33 which is thus retained at the maximum reading until reset by a knob 36. At the rear of the dial 27 is a pointer arm 32a, Fig. 4, having contact pins normally working between contact blocks 43, 44 that are set manually to the desired maximum and minimum readings. When the circuit is closed through the maximum contact 43a, the pump motor is stopped and a relief valve opened. When the minimum contact is closed the valve is shut and the pump restarted. The contact head 32c is pivoted on the arm 32a. and counterweighted at 45, to allow it to yield when the pressure increases too rapidly. Specification 289,249, [Class 143, Weighing- apparatus], is referred to.

Abstract: 573,912. Harmonicas. MAGNUS, F. H. June 25, 1943, No. 10336. Convention date, June 25, 1942. [Class 88 (ii)] A harmonica comprising a reed plate, a plurality of pairs of reeds mounted on the plate, each pair comprising a blow reed and a draw reed, and a body having separate wind cells on one side of the,plate for each pair of reeds is characterized in that each pair of reeds comprises a blow reed and a draw reed arranged in longitudinal alignment with each other. In one construction the harmonica comprises a reed plate A, Fig. 6, which is secured between two body sections D and E, Figs. 7 and 5, by screws 5, Fig. 1, to which assembly is secured a sound chamber 10 and mouthpiece 8. To plate A are secured by rivets 4 pairs of reeds 1, 2, the pairs B being tuned to the notes of the diatonic scale and pairs C to the half tones. Each pair is disposed above one groove 6 or wind cell of section D and below a groove 7 of section E. Grooves C communicate with holes 9 in the mouth piece while grooves 7 communicate with the sound chamber 10. The holes 9 each register with two adjacent grooves 6 and the selection of the desired notes to be played is obtained by a spring-controlled apertured slide valve 16 formed with a fingerpiece or handle 19. In a modification, Fig. 14, two reed plates F, G, are provided on either side of a wind cell block or plate H and between upper and lower casing sections K, T. These sections have grooves 23, 22 forming sound cells leading to a common sound chamber L, and the block H has slots forming wind cells 20 each communicating with upper and lower pairs of reeds. The upper and lower reeds for each slot are in harmony. The harmonica is fitted with a valve, similar to the valve 16, and is also fitted in the sound chamber with a valve which can be moved to prevent the playing of the reeds of one plate. The Specification as open to inspection under Sect. 91 describes also a modification in which the reeds are not arranged end to end, the blow and draw reeds being arranged side by side and each having its own wind and sound cell. This subject-matter does not appear in the Specification as accepted.
