A fifth-wheel coupling for a vehicle, of the kind in which coupling may be effected automatically on backing the tractor beneath the trailer so that a king-pin projecting downwardly from a bearer plate fixed to the trailer is guided by a forked part of a lower bearer plate into engagement with a clutching device associated with the forked bearer plate which is carried by the tractor, comprises a turn-- table assembly adapted to be mounted on a tractor chassis and includes an upper turntable plate connected to a lower turntable plate for relative angular movement in relation thereto, the forked lower bearer plate being mounted on the upper turntable plate for rocking movement about a transverse horizontal axis, and means for locking the forked bearer plate against angular movement relative to the upper bearer plate fixed to the trailer so as to maintain the said transverse rocker axis parallel to the trailer axle during operation of the vehicle, the coupling being characterized in that means are provided for impcsitively latching the turntable plates together so as to position the forked bearer plate with the rocker axis thereof trans-- verse with respect to the longitudinal axis of the tractor so as to facilitate engagement of the king-pin with the clutching device. As shown a lower bearer plate 11 is pivotally mounted on a shaft 10 carried by an upper turntable plate 4. Means 15 are provided to lock the lower bearer plate to the upper bearer plate (not shown) carried by the trailer. An arm 26 is pivoted' at 25 to a lower turntable plate 3 and may be engaged at 30 with a bow spring 28. A projection 24 on the arm 26 is arranged to coact with a notch 23 in the lower turntable plate 3 whereby when the turntable is disposed as shown in Fig. 3, the forkedbearer plate is impositively locked with its rocker axis transverse to the tractor. After the tractor has been coupled to the trailer relative movement of the two portions cf the vehicle forces the end 30 of the lever 26 out of engagement with the spring 28 to allow relative rotation of the turntable plates about a pin 37 . According to a further feature of the invention the lateral stability of the vehicle is increased by so arranging the upper turntable plate 4 that it is displaced laterally when it rotates relatively to the lower plate due to the vehicle following a curved path. To this end the pin 37 is squared at 32 for engagement with the plate 4 and carries a spur wheel 33 which meshes with a rack 34 attached to the lower plate 3. Bushes 36 engage the pin 37 and slide within a lateral slot 35 in the plate 3. The relative angular movement of the plates 3, 4 is limited by stops 7, 8 thereon.

Title: Method for carrying out water forming reactions
IPC: B01D3/36
Filed: 1957-03-11
Abstract: <PICT:0835458/III/1> Water, formed in a chemical reaction, is continuously removed from the reaction vessel containing the boiling organic reactants, of which at least one is volatile at the reaction temperature, by distilling the mixture with a volatile entraining agent which produces a condensate forming two layers of different water-content; the vapours leaving the reaction vessel are condensed without prior fractionation, the condensate is passed to a separation vessel wherein the fresh condensate is first contacted with the layer of greater water content and the condensate-layer having the lesser water content is returned to the reaction vessel.  The separation can be further improved by providing Raschig rings in the separation vessel, or by stirring or vibrating the liquid therein.  In an example, aniline (1 equiv.) and acetic acid (1.2 equiv.) were heated in vessel 3, a mixture of equal parts of butyl acetate and petroleum ether being used as entraining agent.  The vapours are condensed in condenser 5; and the condensate is introduced into the base of vessel 7 where two liquid layers are formed, the water layer being the heavier.  The upper layer is returned to vessel 3 via U-tube 9. After 8 hours the volatiles were removed by heating to 200 DEG  C. The yield of acetanilide was 80% of theory.  Other examples relate to the preparation of diethyl oxalate and triacetin.ALSO:Water, formed in a chemical reaction, is continuously removed from the reaction vessel containing the boiling organic reactants, of which at least one is volatile at the reaction temperature, by distilling the mixture with a volatile entraining agent, which produces a condensate forming two layers of different water-content; the vapours leaving the reaction vessel are condensed without prior fractionation, the condensate is passed to a separation vessel wherein the fresh condensate is first contacted with the layer of greater water-content, and the condensate-layer having the lesser water content is returned to the reaction vessel.  In Example 1, diethyl oxalate is produced by boiling a mixture of oxalic acid dihydrate and ethanol in the presence of trichlorethylene.  The product is purified by vacuum distillation.  Example 2 relates to the preparation of acetanilide by boiling a mixture of aniline and acetic acid, using as entraining agent a mixture of equal parts of butyl acetate and petroleum ether. In Example 3, triacetin is produced by boiling a mixture of acetic acid and glycerol in the presence of chloroform.
