Title: Under-carriage for trailer assembly
IPC: B61J1/10
Filed: 1957-07-18
Abstract: 868,076. Transferring freight containers between vehicles. FELBURN, J. P. July 18, 1957 [July 27, 1956], No. 22765/57. Class 78(4). The body of a road trailer is transferred to a rail vehicle 128 by first backing one end so that a fifth wheel type coupling 62 on the body engages a king-pin 142 on the rail vehicle, and then turning the body, either by use of a mobile hoist or by wheeled rest-bars supporting the front end of the body until the body is in alignment with the rail vehicle. Two bodies may be supported on a single flat car in this way. The road trailer shown is connected to the tractor 20 by a fifth wheel coupling 46 and has a longitudinally sliding engagement with its undercarriage 70, which is independently carried from the tractor 20 through a drawbar 110 whose length may be adjusted. Thus in transferring the body from the trailer to the said car the trailer is first reversed until a portion 150 of the undercarriage abuts the side of the flat car and the coupling 110 is then released so that it can telescope as the body of the trailer is pushed on to the flat car. A hook 162 at the front end of the body can be engaged by a mobile crane which serves to swing the body on to the flat car.

Abstract: 600,820. Filters. BRITISH TANKER CO., Ltd., and McKINNON, J. V. Nov. 23. 1944, No. 23295. [Class 46] A filter for liquids comprises a helical filtering element mounted between two sleeves the distance apart of which is adjustable by means of a bolt or spindle extending through the filtering element, one at least of the sleeves being inwardly flanged to confine one end of the filter coil and being provided in a corresponding recess in the filter casing so as to be axially movable for the adjustment of the coil. As shown in Fig. 1, a filter casing a is provided with end covers a<SP>2</SP> recessed to receive flanged sleeves a<SP>4</SP> which confine the ends of a helical filter coil b. The coil is supported internally by an apertured cylindrical frame d. A bolt c screw-threaded to engage a hole in the lower sleeve a<SP>4</SP> extends through a guide a<SP>3</SP> in the upper cover a<SP>2</SP> and is screw-threaded at its upper end to engage a nut a<SP>21</SP>. A collar a<SP>10</SP> fits within a recess all on the guide a<SP>3</SP>, in the normal position of the bolt. The position shown is that in which the nut a<SP>21</SP> has been pressed down against the action of a spring e so that the turns of the helix b have been separated to facilitate cleaning thereof by reverse flow of liquid, or by compressed air. The openings between the turns may be adjusted by removing the bolt c from the filter casing and adjusting the position of the lower sleeve a<SP>4</SP> on the bolt. They may also be adjusted by turning the nut a<SP>21</SP> on the bolt. In a modification the spring e is dispensed with and the nut is rotatable but not slidable with respect to the upper cover a<SP>2</SP>. In a further modification the nut in addition to having screw-threads in the bore is also screw-threaded on its outer surface to engage a thread in a recess in the upper cover a<SP>2</SP>. The pitch of the outer screw-thread is different from that of the inner thread, and a small or large adjustment of the turns of the helix is obtainable according as the screw-threads are of the same or of opposite sense. In a further modification shown in Fig. 7, the adjustment of the turns of the helix is made by means of cams f pivotally connected to the bolt c, the cams being connected to a lever h the position of which can be adjusted by means of a screw i on a stirrup bracket j. For a quick extension of the helix the bracket j can be swung aside to release the lever h. In the arrangement shown in Fig. 3, the sleeve a<SP>4</SP> is slidable but not rotatable in the lower cover a<SP>2</SP> and its position is adjusted by turning the bolt c by a spanner engaged on the end c<SP>1</SP>.

Abstract: 691,489. Regulating. BRONZAVIA SOC. ANON. Sept. 25. 1950 [June 23. 1950], No. 23389/50. Class 7 (vi) [Also in Group XXIX] A device for modulating a controlled pressure as a function of variations in the pressure of a controlling fluid so that an increase in the. controlling fluid pressure causes a decrease in the controlled pressure and vice versa, comprises a hollow piston valve 6 slidable in a sleeve 2 and subjected to the spring-like action of a stack of evacuated capsules 13 in a chamber 11 in which exists the controlling pressure. The controlled pressure exists in the interior of the valve and a conduit 27 connected, e.g. to a servomotor utilizing said pressure. The controlled fluid is supplied by a line 28 through a restriction 29 and acts to move the valve against the spring force of capsules and open an exhaust aperture 26. The device is shown associated with the output regulator of a fuel injection pump device for internal-combustion engines, the controlling pressure being that of the combustion air and the controlled pressure being used to control the regulator piston 32 which is coupled to a sleeve 34 by a pin 35 and rotated by a shaft 38 in timed relationship to the engine. The piston has a groove 39 extending from a land 42 of varying width which closes a series of ports 45 as it rotates, there being the same number of ports as there are cylinders in the engine. Each port con-. nects with an injection pump for a particular cylinder, and the injection stroke of each pump lasts for the time in which the respective port is covered. Thus by moving the piston 32 and hence the land 42, this time period and hence the quantity of fuel injected per piston stroke can be varied. Fuel is supplied by a line 44 to the interior of the piston 32 whence it passes through apertures 43 to the groove 39, the ports 45 and the pumps. Thus, if the air pressure falls, the pressure in the line 27 increases and moves the piston 32 to the right to decrease the amount of .fuel injected, and vice versa. To prevent changes in the fuel pressure affecting the position of the piston 32, a capsule 47. subjected to the fuel pressure. acts on the capsules 13. Specification 689,706, [Group XXVIII], is referred to.
