Title: Improvements relating to road trailers
IPC: B60G5/06
Filed: 1959-02-10
Abstract: 859,289. Steering trailers. PRATOLONGO, M., and KEAN, C. Feb. 10, 1959, No. 4650/59. Class 79(5). [Also in Group XXXII] A trailer vehicle (front half only, shown in Fig. 1a) comprises a chassis frame Z supported on a series (as shown 5) of bogies Y, each bogie having steerable wheels operated by movements of a drawbar 207. Greater steering movements are given to the wheels at the ends of the trailer than to the intermediate bogies, as shown in Fig. 25. A cross-bar 205 rigid with the drawbar 207 is connected by rods 208 to a cross-bar 201. The latter is connected by rods 210 to respective steering boxes 83, for the leading bogie, and by rods 202, to similar steering boxes for the second bogie. The crossbar 201 is also connected by rods 204 to a further cross-bar 201 a, which is connected by diagonally disposed rods 209 to a corresponding cross-bar 201a on the other side of the transverse centre line of the trailer. The diagonal arrangements of the rods 209 reverses the direction of steering of the wheels on the trailing half of the trailer. Each steering gearbox 83 is connected to a respective transverselydisposed shaft 100 (see also Fig. 12) which is connected to a corresponding shaft 62 journalled in the bogie frame by means of a clutch mechanism 92. The clutch mechanism is arranged to be disengageable on operation of hooks 129 by which the chassis frame is connected to the bogie frame of the respective bogie to permit the frame to be lifted clear of the bogies when desired. The shaft 62 is coaxial with the journals of suspension arms 212 which carry the road wheels. The shaft 62 carries a pair of sprocket wheels 50 each of which is connected by a chain 152 to a sprocket 110 journalled in the corresponding arm 212. A shaft 103, rigid with the corresponding sprocket 110, is connected by a linkage 102, 36, to a steering arm 4 which is rigid with a king-pin 8 carrying a pair of road wheels at its lower end. The difference in steering angle between the wheels of respective bogies is determined by the different radial distance of the connections of the rods connected between the arms 201 and corresponding gear-boxes 83. The difference in steering angles between the two pairs of wheels mounted on the same side of each bogie is achieved by adjusting the length of the arm 101.

Patent GB-573763-A (GB)
Title: Improvements in or relating to the manufacture of halogenated organic acids
IPC: C07C51/25
Filed: 1941-04-10
Abstract: Unsaturated a -chlor acids are made by oxidation with molecular oxygen of a -chlor a -b -unsaturated aldehydes at temperatures below 100 DEG  C.  Preferably the aldehyde is in solution in a solvent and the quantity of aldehyde present in the solvent at any time should be small, which may be effected by adding the aldehyde intermittently in portions or continuously.  An oxygen-carrying catalyst such as a compound of copper, manganese, cobalt, nickel, vanadium, iron, chromium, uranium, tungsten or molybdenum may be employed.  If the solvent is an alcohol, the product is the corresponding ester.  Some hydrochloric acid is evolved in the reaction, and to prevent this adding on to the aldehyde, water may be added or the hydrochloric acid may be carried off by excess of the oxidizing gas, or the catalyst may be a carboxylate which reacts with hydrochloric acid. Examples describe the oxidation of a -chloracrolein and a -chlorcrotonaldehyde, in one case ethyl alcohol being present to produce ethyl a -chloracrylate.  Solvents specified in the examples are acetone and acetic acid, but in one case no solvent is used, the temperature being 10-20 DEG  C. Specifications 514,619, 560,166 and 573,723 are referred to.

Title: Process for the coagulation and precipitation of products such as asphaltic materials, resins and paraffins, with particular application of the said process to the elimination of asphalt from mixtures of hydrocarbons
IPC: C10G21/14
Filed: 1931-02-18
Abstract: In a process for removing asphalt and resins from hydrocarbons such as crude mineral oils or coal tar, the oil is treated with small amounts of dilute acid and a solvent.  For example, shale oil or lignite tar or oils obtained by extracting the corresponding raw materials with solvents, are dissolved in petroleum spirit, and the resulting solution is treated at slightly elevated temperature with a small amount of 5 to 30 per cent sulphuric acid.  The resulting precipitate of asphalt and resins is separated together with the dilute acid and the solution is cooled to precipitate the paraffin wax, which is then separated by filtration or by centrifuge.  The separated aqueous layer may be treated to recover the acid.  The treatment with dilute acid may precede the addition of solvent. French Specification 536,172 is referred to.

The fixed and moving contacts 2<SP>1</SP>, 3<SP>1</SP> of a circuit breaker are mounted on arms extending substantially parallel to one another so that, upon short circuit, electrodynamic repulsion between the arms 2, 3 separates the contacts sufficiently for a snap spring 7 to pass overcentre. The contacts are reclosed by a rod 14 and can be tripped open under less severe overload by thermal and electromagnetic devices acting to release the support 8 of the overcentre spring 7. In Figs. 4-10 (not shown) twin series connected movable contacts 23, 23<SP>1</SP> are pivoted on a slidable carrier 31 movable by a pivoted handle 54. A pin 37 slides in carrier 31 and supports overcentre springs 39 attached to each contact arm 23. A bar 41 is latched against a spring bias by an overload bimetal 56 which carries the tripping electromagnet. In closing handle 54 drives carrier 31 downwards pin 37 being held by a latch 66 until the springs pass overcentre when latch 66 is released by a projection 70. Upon overload bimetal 56 releases bar 41 to drive pin 37 downwards moving the springs overcentre. Upon short circuit electrodynamic repulsion separates the contacts, pin 37 moving down under the action of the overcentre springs. The latches are reset by moving the handle 54 to the off position. In Figs. 15-22 (not shown) a rectilinearly moving bridging contact 106 is slidable against spring bias 112 on a rod 111 normally latched to a carrier 122 but released therefrom by bimetal or electromagnetic trips or by electrodynamic repulsion of contact 106. In Fig. 23 (not shown) the contact arm 208 is pivoted on a latched arm 210 and connected by snap springs 215 to a handle 213. On overload the latch 218 is withdrawn to release the contacts in the usual fashion. On short circuit contacts 206, 209 are separated by electrodynamic repulsion but in this case it is necessary that the electromagnetic trip act sufficiently fast to release the arm 210 before the contacts can reclose.
