Title: Improvements in bogies for railway vehicles
IPC: B61F5/44

Abstract: 464,379. Adjusting railway - vehicle axles on curves. V.R.L. COMPAGNIE INTERNATIONALE D'EXPLOITATION DES INVENTIONS LIECHTY POUR VEHICULES SUR RAILS. Aug. 17, 1936, No. 22575. Convention date, Aug. 17, 1935. [Class 79 (v)] [Also in Group XXXII] In a railway vehicle of the kind in which the body a is mounted upon bogies c equipped with radiating axles or stub-axles d, e, the setting of which on a curve is positively effected owing to the relative displacement between the body and bogie frames, the radiation of the axles is controlled by one or more devices, such as linkage systems, disposed laterally, i.e. non-centrally, in the bogie frame. In the construction shown in the Figure, the axles d, e are pivoted at their ends f, f<1> to the bogie frame, and the displacement of their other ends is effected by a system of pivoted links h, i, i<1>, i<2>, the pivots 5, 7 being fixed respectively in the bogie and body frames. The relative displacement of these pivots on a curve causes the links i<1>, i<2> to set the axles d, e in correct radial position: In a modification, the axles are pivoted to the bogie frame above their mid-points.. In other constructions individually mounted stubaxles are employed, the setting of which is controlled either by two independent laterallydisposed systems of links, or by two interconnected systems.

Title: Novel isomerisation process
IPC: C07D311/90
Filed: 1960-06-29
Abstract: Thioxanthenes of the formula <FORM:0899898/IV (b)/1> (wherein Y is a di-substituted amino group) are isomerized by treatment with oxalic acid and, if desired, the salt obtained is converted into the free base.  The process may be effected with aqueous or alcoholic oxalic acid at a temperature up to the boiling point of the mixture or by fusing the oxalate addition salt, preferably in the presence of excess oxalic acid.  The starting material is one isomer or a mixture of isomers containing one in excess over the other, and in the fusion process it may be mixed with the corresponding 9-hydroxy-9-(N,N-disubstituted-aminopropyl)-halogenated thioxanthene which is concomitantly dehydrated.  Advantageously a mixture of approximately equal proportions by weight of (a) a mixture of isomers of a thioxanthene of the above formula containing one isomer in excess over the other and (b) the corresponding 9 - hydroxy - 9 - (N,N - disubstituted - aminopropyl)-compound is fused in the presence of excess oxalic acid, one isomer is isolated (after conversion to the free base if desired), to the mother liquid is added a quantity of the said 9-hydroxy-compound equivalent on a weight basis to the quantity of the isomer which has been separated and the resulting mixture is subjected to a further acid treatment and isolation step. It is stated that this process results in approximately equal proportions of the two isomers and thus, if one isomer is separated, e.g. by fractional crystallization, and the residual isomer subjected to repeated isomerization, practically complete conversion to the desired isomer can be effected.  Examples describe the preparation of the higher melting isomer (designated the trans form) of 2-chloro-9-(o -dimethyl-amino-propylidene)-thioxanthene.  Also referred to are compounds in which Y in the above general formula represents any dialkylamino group or a piperidino, morpholino, piperazino or 4-(hydroxy-ethyl)-piperazino group.  Specification 829,763 is referred to.

[Class 87 (ii)] [See also Group X] Precast concrete or cement building-blocks are manufactured by separately moulding an outer face a under great pressure so that it is impervious to moisture and thereafter bonding the face a to a relatively weak porous body portion e by an intermediate layer b of concrete. The outer face may be formed with grooves or channels c<1> or with undercut or wedge-shaped frogs or projections and may have metal clips c partly embedded therein. The clips, Fig. 4, may be formed from wire bent to form two U-shaped loops in one plane with a third U-shaped loop at right angles thereto. The third loop is embedded in the outer face, preferably in the grooves c<1>, and the other loops are bent outward so that they may be embedded in the layer b. An aggregate of shingle, sand, ballast, stone chips or other impervious material may be used for the face a which may be white or tinted, and its external surface may be plain or patterned and may be wire-brushed or rubbed or ground to remove any adhering cement skin. It may be moulded in an hydraulic press with a pressure up to one ton per square inch exerted on the flat face or at the edge. The body portion may contain porous material such as broken brick or brick waste, pumice or well-burnt furnace clinker. When hard, the outer face is placed face downward in a mould, the layer b is poured in, wooden cores for cavities f may be positioned and the mould filled with the porous concrete and strickled or tamped. Plain, channeljointed, L-shaped corner, stanchion or stringer blocks may be produced. The Provisional Specification refers to Specifications 248,512, [Class 87 (i)], 292,425, [Class 87 (ii)], and 295,470, [Class 87 (i)].
