Abstract: 204,687. Junkers, H. Oct. 2, 1922, [Convention date]. Planes connecting to machine; fuselages; land wheels.-Large free spaces with lateral openings are formed in aeroplane fuselages and the bracing thus dispensed with is replaced by strongly constructed strutwork connecting the fuselage to the supporting surface so as to resist bending, shear, and torsional forces. The Figure shows an aeroplane having a. triangular longitudinal girder 10 along its base, and its front and rear portions resistant to torsion, points 5 on the front portion being connected by sets of tripod struts 7 to the central section 3 of the supporting-plane which is connected at the points 6 to the rear portion of the fuselage by triangular frames 8. One side 11 of the fuselage is continuous but the other has a door 12 with a beam 13 at its upper edge which can be secured when the door is shut to take compression or tension forces and serve as an additional member of the structure. The main undercarriage struts 16 may be secured at the points 5. Modifications are described in which the front and rear parts of the fuselage are hinged together at the base and connected to an upper plane at their upper parts by rigid strut work or fins having pivotal connections to one or other of the plane or fuselage parts. Or extensions on one of the fuselage parts may be connected to the other by struts extending in longitudinal vertical planes, and a supporting surface is secured to the structure at at least three points. Rigid joints may be substituted for true hinged joints. Multiplane constructions may be employed, and a biplane may be obtained by mounting a lower supporting-surface on the floor of the body.

Abstract: 1,063,296. Electrical digital calculators. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. May 25, 1964 [May 31, 1963], No. 21877/63. Heading G4A. A computer system includes data transfer means enabling any of a number of computers to call for connection to any other, or any peripheral unit, and means for selecting which of a number of such calls shall be taken next, according to a built-in system of priorities, and stored information on the availability and serviceability of the called units. The units are arranged in groups (of twelve, as described) with a common connection unit for each group, and each computer unit can send a transfer demand signal over its line (DM, Figs. 1A, 1B, not shown), to its connection unit and thence to a highway channel allocater over a line (M) (one for each unit) where a number designating the highest-priority calling unit is recorded. this is signalled via lines (A, E and 2) to all connection units to select the calling unit over lines (Y), which then sends its data-transfer instruction over lines (X, 1, and B) to the highway control unit. This instruction includes the designation of the called unit, which is checked in the compatability unit to ensure that the unit is not busy (if it is busy, and is not due to be released soon, the projected transfer is rejected), the message length (which is reduced as each block of data is transferred) and the address in the called unit and instructions therefor which are subsequently transferred via the divergence unit to the connection units to select and control the called unit. Data can then be routed between the units over a highway (3). A number of highways may be provided to allow more than one concurrent data transfer, and data may be stored to indicate the non-serviceability of units, and to enable the automatic selection of alternative units where appropriate. The units are illustrated schematically in Figs. 2-7 (not shown).

Title: Butadiene telomers and process for preparing same
IPC: C08F36/04
Filed: 1965-05-26
Abstract: Butadiene telomers are prepared by telomerizing butadiene in the presence of at least one free-radical forming compound as catalyst at at least 100 DEG  C. in at least one chan transferring solvent, the butadiene and catalyst being introduced into the reaction vessel initially containing only the solvent at a desired temperature and the rate of introduction of the butadiene being the same as its rate of consumption in the reaction.  The free radical forming compound is e.g. an organic peroxide such as ditertiary butyl peroxide, dilauroyl peroxide, dibenzoyl peroxide, cumene hydroperoxide and tertiary butyl hydroperoxide, or an azo compound e.g. azo bisisobutyronitrile. The solvent may be a saturated aliphatic hydrocarbon containing a tertiary carbon atom, a halogenated aliphatic hydrocarbon, a saturated aliphatic primary or secondary alcohol or a ketone.  The preferred solvents are aromatic hydrocarbons substituted by aliphatic groups containing at least one labile hydrogen atom, particularly those of general formula <FORM:1102233/C3/1> wherein R1 represents a benzene nucleus having 5-n hydrogen atoms, R2 and R3 are hydrogen atoms or alkyl, aryl or phenyl alkyl groups, X is a hydrogen or halogen atom or a nitro or hydroxyalkyl group and n is an integer in the range 1 to 4. Cumene and xylene are specified examples.  The telomers produced have a molecular weight of 300 to 3000, an iodine number of 280 to 450 and about 65% of their double bonds are trans and about 25% are in the form of vinyl groups.  In the examples the catalyst used is ditertiary butyl peroxide and the solvents are cumene, toluene, xylenes and n-butanol. The telomers can be used for preparing coatings, which can be hardened by oxidation or free radicals, and as plasticizers.
